Refer to fig. 1 and 4. The intermittent reciprocating movement of the swinging cross plate 16 driven as described above is explained in detail below.
Firstly, through the transmission of the first shaft 3 and the second shaft 4, the first screw 23 and the second screw 24 can synchronously rotate, the thread directions of the first screw 23 and the second screw 24 are the same, but the first screw 23 and the second screw 24 can oppositely rotate due to the transmission meshing relationship of the first gear 5 and the second gear 6;
after the limiting guide rod 14 penetrates through the transmission plate 15, the motion track of the transmission plate 15 is limited, so that the transmission plate 15 can only move in the axial direction of the limiting guide rod 14;
similarly, the first rotating connecting plate 25, the second rotating connecting plate 26, the swinging transverse plate 16, the connecting column 27, the first guide column 28, the tension spring 29 and other structures on the transmission plate 15 can move in the axial direction.
Referring to fig. 4, under the influence of the elastic force of the tension spring 29, the first rotating connecting plate 25 and the second rotating connecting plate 26 are in a state of being in different straight lines in a natural state, that is, a certain included angle exists between the first rotating connecting plate 25 and the second rotating connecting plate 26, the first rotating connecting plate 25 is limited by the limiting column 30, the deflection angle is fixed, the transverse swinging plate 16 on the second rotating connecting plate 26 is influenced by the first screw 23 or the second screw 24, the rotation angle is also limited, and the transverse swinging plate 16 is alternatively matched with the external threads on the first screw 23 and the second screw 24 through the internal spiral groove 22 in the second clamping groove 21.
Referring to fig. 4, at this time, the inner spiral groove 22 corresponding to the second screw 24 on the swinging cross plate 16 is matched with the outer contour of the second screw 24, and since the movement track of the swinging cross plate 16 is limited as described above, the inner spiral groove 22 and the rotating second screw 24 generate relative movement, and the swinging cross plate 16 moves towards the direction away from the vertical plate 2 under the guidance of the outer contour track on the second screw 24.
In the process, the swing transverse plate 16 is deflected by the rotation connecting plate II 26, so that the rotating arm 17 on the swing transverse plate continuously finishes clamping and locking on the stainless steel slender rod 9 to be processed through the connecting frame 18 and the clamping block 19, and the axial movement of the stainless steel slender rod 9 to be processed can be smoothly realized along with the axial movement of the swing transverse plate 16, so that the feeding operation of the stainless steel slender rod 9 to be processed and the continuous and complete grinding operation of the grinding disc 8 on the stainless steel slender rod 9 to be processed can be realized.
In the moving process of the swing transverse plate 16, the rotating connecting plate one 25 moving synchronously with the swing transverse plate 16 is contacted with the inclined guide plate two 33 through the guide column one 28 on the guide transverse plate one and generates extrusion, and under the influence of the inclined placing angle on the inclined guide plate two 33, the guide column one 28 and the rotating connecting plate one 25 gradually rotate to the vertical state, under the cooperation of the tension spring 29, the rotating connecting plate one 25 and the rotating connecting plate two 26 are gradually positioned on the same straight line, and the tension spring 29 is stretched to the longest, and at this moment, the balance state is realized.
The balance state is broken along with the further axial movement of the first guide column 28, the elastic force of the tension spring 29 is released, so that the first rotating connecting plate 25 and the second rotating connecting plate 26 quickly deflect towards the direction close to the first screw 23, the swinging transverse plate 16 on the second rotating connecting plate 26 deflects along with the first rotating connecting plate, the swinging transverse plate 16 is separated from the contact with the second screw 24, and the clamping locking of the first clamping groove 20 on the thin stainless steel rod 9 to be processed is released along with the second rotating connecting plate 26;
and then the other inner spiral groove 22 of the swinging transverse plate 16 is contacted and matched with the outer thread sliding groove on the first screw rod 23; it is mentioned above that the screw threads of the first screw 23 and the second screw 24 are in the same direction but in opposite directions, so that the inner spiral groove 22 will carry a plurality of structures such as the transmission plate 15, the first rotating connecting plate 25, the second rotating connecting plate 26 and the like to axially move towards the vertical plate 2 by swinging the transverse plate 16 after completing the matching with the screw thread of the first screw 23;
similarly, referring to fig. 1, in the axial movement process towards the vertical plate 2, the second guide post 31 and the first inclined guide plate 32 are in contact and generate extrusion, so that the angle of the swinging transverse plate 16 deflects again, the inner spiral groove 22 corresponding to the second screw rod 24 on the swinging transverse plate 16 is matched with the second screw rod 24 again, and simultaneously along with the deflection of the swinging transverse plate 16, the rotating arm 17, the connecting frame 18 and the clamping block 19 on the swinging transverse plate can realize clamping and locking of the thin stainless steel rod 9 to be processed again, and then the thin stainless steel rod 9 to be processed is dragged along the axial direction, so that the continuous feeding process of the thin stainless steel rod 9 to be processed can be realized under the continuous operation.
Further, a cutting blade 34 is fixedly connected to the lower surface of the rotating arm 17, the cutting blade 34 is a right triangle blade, and a cutting edge on the cutting blade 34 is located at a hypotenuse of the right triangle blade, and the cutting edge faces the fixed transverse plate 11.
Referring to fig. 1 and 4, in the above process, when the transmission plate 15, the swinging cross plate 16 and other structures axially move towards the vertical plate 2, the swinging cross plate 16 and the rotating arm 17 are finally subjected to rapid angular deflection, the rotation deflects towards the fixed cross plate 11, and then the to-be-machined stainless steel thin rod 9 on the fixed cross plate 11 is cut off by the cutting blade 34 on the rotating arm 17, and since the distances of the swinging cross plate 16 carrying the cutting blade 34 to axially reciprocate are the same, the to-be-machined stainless steel thin rods 9 which are correspondingly cut are also equal in length, so that the distance cutting effect is realized, and after the cutting is finished, the to-be-machined stainless steel thin rods 9 continue to move towards the direction far away from the vertical plate 2, and the release of the to-be-machined stainless steel thin rods 9 is realized through the deflection of the swinging cross plate 16 and the rotating arm 17.
Cutting blade 34 is the right triangle blade, and the cutting edge on cutting blade 34 is in the hypotenuse department of right triangle blade, and this cutting edge is towards fixed diaphragm 11, through above-mentioned operation, can make cutting blade 34 smooth treat the cutting that the processing stainless steel slender pole 9 carried out the completion, can not blockked and blocked by fixed diaphragm 11.
Furthermore, the pressing rollers 35 are detachably mounted at the ends, far away from the vertical plate 2, of the first screw 23 and the second screw 24, and the two pressing rollers 35 are parallel to each other.
Through the rotation that two pressfitting rollers 35 are driven to screw rod 23 and screw rod two 24, can extrude the thin pole 9 of stainless steel of treating processing that is cut off and drops, make it flatten the shaping to satisfy the demand of in-service use, after accomplishing to flatten the shaping, carry out sharpening operation to the one end of treating processing thin pole 9 after flattening again, punch the operation through laser at the other end.
Furthermore, a blocking plate 36 supported and fixed by an external frame is arranged above the pressing roller 35, and an inclined sliding plate 37 for sliding and guiding the cut stainless steel slender rod 9 to be processed is fixedly connected to the bottom of the blocking plate 36.
