Description

Auxiliary punching equipment for mold parts processing

Technical Field

The invention relates to the technical field of mold parts processing, and in particular to an auxiliary punching device for mold parts processing.

Background technique

Mold parts processing is a process of converting raw materials into finished mold parts. It is one of the important links in the manufacturing industry. The processing of mold parts involves cutting, milling and drilling, among which drilling is a very important step in mold parts processing.

In order to obtain a specific aperture size, shape or position to meet specific manufacturing requirements and improve the efficiency and accuracy of the manufacturing process, the needle-shaped mold accessory is placed in an inclined state for punching, and two holes need to be punched symmetrically along the circumference of the needle-shaped mold accessory. At present, a punching device is used to punch holes in the needle-shaped mold accessory. When punching, the needle-shaped mold accessory is first placed in a mold accessory fixture, and the needle-shaped mold accessory is clamped by the mold accessory fixture. Then, the mold accessory fixture is tilted and placed on the workbench of the punching device, so that the needle-shaped mold accessory is in an inclined state for punching, and then the punching device is manually used to punch the holes. The clamp block on the punching device clamps and fixes the mold accessory fixture in an inclined state to ensure that the needle-shaped mold accessory remains in an inclined state for punching. After completing one punching, the clamp block on the punching device is manually used to loosen the mold accessory fixture, and the mold accessory fixture drives the needle-shaped mold accessory to rotate 180 degrees, so that the next position of the needle-shaped mold accessory that needs to be punched is rotated to align with the electric drill of the punching device, and then the mold accessory fixture is tilted again and the clamp block clamps and fixes the mold accessory fixture. This requires many and cumbersome manual operation steps, resulting in high labor intensity for workers and low punching efficiency.

The jacking assembly 10 includes two slide plates 101 that are symmetrically slidably connected to the rotating plate 7 through a slide groove and can move closer to and away from each other. The two slide plates 101 are hinged on the side where they are close to each other. The two The top plate 102 is hinged, a spring II 103 is connected between the slide plate 101 and the rotating plate 7, the two slide plates 101 are connected to the sides facing each other with wedge plates I 104, the side of the wedge plate I 104 facing away from the slide plate 101 is an inclined surface, a push plate II 11 is connected to the housing of the electric drill 4, the push plate II 11 can contact the inclined surface on the front wedge plate I 104 as the electric drill 4 moves downward, and squeeze the inclined surface on the front wedge plate I 104 to move the front slide plate 101 backward, an L-shaped positioning plate 12 is connected to the rear side of the top of the workbench 1, the L-shaped positioning plate 12 is located on the front side of the mounting plate 2, and the L-shaped positioning plate 1 2 is used to position the mold accessory fixture 5. The rotating plate 7 is provided with a clamping assembly 8. The clamping assembly 8 includes two clamping blocks 81 that are symmetrically connected to the rotating plate 7 in a sliding manner and can move closer to or away from each other. The clamping block 81 is located above the top plate 102. A spring Ⅰ82 is connected between the clamping block 81 and the rotating plate 7. The two clamping blocks 81 are connected to a wedge block 83 on the sides facing away from each other. The side of the wedge block 83 facing away from the clamping block 81 is an inclined surface. Two push plates Ⅰ9 are symmetrically connected to the housing of the electric drill 4. The height of the bottom of the push plate Ⅰ9 is higher than the height of the bottom of the push plate Ⅱ11. The two push plates Ⅰ9 move with the rotation of the top plate 102. The electric drill 4 moves downward and can contact the inclined surfaces on the two wedge blocks 83 respectively, and push the two wedge blocks 83 closer to each other. A driving assembly 13 for driving the rotating shaft 6 to drive the rotating plate 7 to rotate is provided on the top right side of the workbench 1. The driving assembly 13 includes a connecting plate 131 that is slidably connected to the top right side of the workbench 1 through a sliding groove and can move forward and backward. A ratchet bar 133 that can move left and right is slidably connected to the connecting plate 131 through a sliding rod Ⅰ132. A spring Ⅲ134 is connected between the ratchet bar 133 and the connecting plate 131. A ratchet 135 is connected to the rotating shaft 6, and the ratchet 135 is engaged with the ratchet bar 133.

Put the needle-shaped mold accessory that needs to be punched into the mold accessory fixture 5, and the mold accessory fixture 5 can clamp and fix the needle-shaped mold accessory. Then, place the mold accessory fixture 5 at the hinge of the two top plates 102, so that the needle-shaped mold accessory is directly below the electric drill 4, and control the telescopic rod of the electric push rod 3 to extend to push the electric drill 4 with the push plate Ⅰ9 and the push plate Ⅱ11 to move downward. The downward movement of the push plate Ⅱ11 can squeeze the inclined surface on the front wedge plate Ⅰ104, so that the front wedge plate Ⅰ104 moves backward, thereby pushing the front slide plate 101 to move backward, while the rear slide plate 101 is supported by the rotating plate 7 and cannot move backward. The front slide plate 101 moves backward, so the front top plate 102 cannot move backward. The front top plate 102 swings upward, pulling the rear top plate 102 upward, and then pulling the rear slide plate 101 forward. The springs II 103 on the front and rear sides are compressed accordingly. The upward swinging of the top plate 102 can lift the mold accessory fixture 5 upward to an inclined state, so that the needle-shaped mold accessory remains in an inclined state for punching. The mold accessory fixture 5 can be positioned by the L-shaped positioning plate 12 to prevent the mold accessory fixture 5 from sliding off the rear top plate 102 when it is tilted. Since the height of the bottom of the push plate I9 is higher than the height of the bottom of the push plate II11, after the top plate 102 lifts the mold accessory fixture 5 upward to an inclined state, the two push plates I9 move down to contact the inclined surfaces on the two wedge blocks 83 respectively, so that the two push plates I9 continue to move down to push the two wedge blocks 83 closer to each other, so that the two clamping blocks 81 approach each other to clamp and fix the mold accessory fixture 5 in an inclined state, and the spring I82 is stretched accordingly to ensure that the needle-shaped mold accessory remains in an inclined state for punching. After the clamping block 81 clamps and fixes the mold accessory fixture 5 in an inclined state, the drill bit on the electric drill 4 moves down to contact the needle-shaped mold accessory to punch the needle-shaped mold accessory. After completing one punching, the telescopic rod of the electric push rod 3 is controlled to shorten to pull the electric drill 4 to move up with the push plates Ⅰ9 and Ⅱ11. When the push plate Ⅰ9 moves up to disengage from the wedge block 83, under the reset action of the spring Ⅰ82, the two clamping blocks 81 move away from each other to release the mold accessory fixture 5. When the push plate Ⅱ11 moves up to disengage from the front wedge plate Ⅰ104, under the reset action of the spring Ⅱ103, the two slide plates 101 can move away from each other to pull the top plate 102 to swing downward to a horizontal state. The mold accessory fixture 5 swings down back to a horizontal state under the action of its own gravity, so that the needle-shaped mold accessory returns to a vertical state. Then, the connecting plate 131 is moved forward and backward to make the ratchet bar 133 move forward and backward. When the ratchet bar 133 moves forward, it is squeezed by the ratchet teeth on the ratchet wheel 135 to move to the right, and the spring III 134 is compressed accordingly. When the ratchet bar 133 moves forward and disengages from the ratchet wheel 135, under the reset action of the spring III 134, the ratchet bar 133 moves to the left and resets. The ratchet bar 133 moves backward to push the ratchet wheel 135 to rotate, so that the rotating shaft 6 drives the rotating plate 7 to rotate, and then the top plate 102 drives the mold accessory clamp 5 to rotate, so that the needle-shaped mold accessory rotates and turns over to align the next position to be punched with the electric drill 4, so as to adjust the punching position of the needle-shaped mold accessory. When the electric drill 4 moves down again to punch holes, the above operation can be repeated to lift the mold accessory clamp 5 upward to an inclined state again, and clamp and fix the mold accessory clamp 5 again. In this way, the device can automatically lift the mold accessory clamp 5 upward to an inclined state to keep the needle-shaped mold accessory in an inclined state for punching, and can automatically clamp the mold accessory clamp 5 to ensure that the needle-shaped mold accessory remains in an inclined state for punching, thereby reducing manual operation, reducing labor intensity, and thus improving punching efficiency.

Please refer to Figure 7. A pushing assembly is provided on the outer wall of the electric drill 4, and the pushing assembly includes a connecting rod 141 connected to the outer wall of the electric drill 4. The bottom end of the connecting rod 141 is connected to an inclined plate 142. The top of the connecting plate 131 is connected to a wedge plate II 143. The top of the wedge plate II 143 is an inclined surface. The inclined plate 142 moves downward to contact the inclined surface of the top of the wedge plate II 143. A spring IV 144 is connected between the connecting plate 131 and the workbench 1.

The electric drill 4 moves downward, drives the inclined plate 142 downward through the connecting rod 141 to contact the inclined surface at the top of the wedge plate II 143, and squeezes the inclined surface at the top of the wedge plate II 143 so that the wedge plate II 143 drives the connecting plate 131 to move forward, and the spring IV 144 is stretched accordingly. When the inclined plate 142 moves upward to disengage from the wedge plate II 143, the connecting plate 131 moves backward and resets under the resetting action of the spring IV 144. In this way, there is no need to manually make the connecting plate 131 drive the ratchet bar 133 to move forward and backward. After completing a punching operation, the needle-shaped mold accessory can be automatically turned over to automatically adjust the punching position of the needle-shaped mold accessory, thereby further reducing manual operation and further reducing labor intensity.

Please refer to Figure 7. A limit assembly is provided on the left side of the top of the workbench 1. The limit assembly includes a wedge-shaped block 153 that is slidably connected to the left side of the top of the workbench 1 through a slide rod Ⅱ151 and can move left and right. The wedge-shaped block 153 is located on the left side of the ratchet 135. The rear side of the wedge-shaped block 153 is an inclined surface. The ratchet 135 can rotate to contact the inclined surface on the rear side of the wedge-shaped block 153. A spring Ⅴ152 is connected between the wedge-shaped block 153 and the workbench 1.

When the ratchet 135 rotates, the ratchet teeth on it can contact the inclined surface on the rear side of the wedge-shaped block 153 and squeeze the inclined surface on the rear side of the wedge-shaped block 153 to move the wedge-shaped block 153 to the left, and the spring V152 is compressed accordingly. When the ratchet teeth on the ratchet 135 pass over the wedge-shaped block 153, under the resetting action of the spring V152, the wedge-shaped block 153 moves to the right and clamps the ratchet 135, which can prevent the ratchet 135 from rotating excessively and push the ratchet 135 to rotate in the opposite direction when the ratchet bar 133 moves forward, thereby ensuring that the needle-shaped mold accessory is turned over after completing a punching operation, thereby improving the accuracy of the punching.

Please refer to Figure 8. A liquid spraying mechanism is provided on the left side of the top of the workbench 1. The liquid spraying mechanism includes a liquid storage cylinder 161 connected to the left side of the top of the workbench 1. Two connecting plates 162 are connected to the outer wall of the liquid storage cylinder 161. The connecting plate 162 on the left side is connected to an infusion tube 163. The infusion tube 163 extends into the liquid storage cylinder 161. The connecting plate 162 on the right side is connected to a nozzle 164 for spraying coolant on the mold accessories. Both the nozzle 164 and the infusion tube 163 are provided with a one-way valve, and an air bag 165 is connected between the nozzle 164 and the infusion tube 163.

The coolant is injected into the liquid storage cylinder 161, and then the airbag 165 is manually squeezed to compress the airbag 165. The airbag 165 is released, and the airbag 165 expands under its own elasticity. When the airbag 165 expands, the coolant in the liquid storage cylinder 161 is drawn into the airbag 165 through the infusion tube 163. When the airbag 165 is compressed, the coolant in the airbag 165 is squeezed into the nozzle 164, and the nozzle 164 then sprays the coolant on the mold accessories to cool the mold accessories.

Please refer to Figure 8. An extrusion plate 17 is connected to the outer wall of the electric drill 4. The extrusion plate 17 can squeeze the airbag 165 as the electric drill 4 moves downward to squeeze the coolant in the airbag 165 into the nozzle 164. In this way, there is no need to manually squeeze the airbag 165 to spray the coolant, which can save labor.
