Description

A stamping jig with protective function

Technical Field

The utility model belongs to the technical field of stamping equipment, and particularly relates to a stamping jig with a protective function.

Background Art

Metal stamping is a manufacturing process that uses a metal stamping die or a series of metal stamping dies to form metal sheets into three-dimensional workpieces. The structural strength of the one-piece stamping workpiece is higher.

During the stamping process, impact force and vibration will be generated when the workpiece to be stamped contacts the jig. The existing stamping jig lacks a suitable buffer structure, which will cause the impact force to be directly transmitted to the jig, increasing the risk of wear and damage to the stamping tool. The lack of a buffer structure will also reduce the accuracy and stability of the stamping process. The unreasonable design of the jig's buffer structure will lead to the impact force cannot be effectively absorbed and dispersed, increasing the vibration and stress of the workpiece to be stamped and the jig, which may cause deformation, cracking and other problems of the workpiece. Therefore, we hope to design a stamping jig with a new structure to solve this problem.

The utility model provides a technical solution: a stamping jig with a protective function, comprising: a base 100, a buffer positioning assembly 200 and a stamping assembly 300. The left side, the right side and the rear side of the upper surface of the base 100 are respectively movably mounted with a buffer positioning assembly 200, and the stamping assembly 300 is mounted above the base 100;

The base 100 includes a bottom plate 110 and a support column 120. A support column 120 is fixed to each of the four corners of the upper surface of the bottom plate 110. A lower die 130 is movably installed in the middle of the upper surface of the bottom plate 110. The stamping assembly 300 includes a cylinder 310, a top plate 320 and a guide plate 330. The top plate 320 is fixed to the upper ends of the four support columns 120. The cylinder 310 is installed in the middle of the upper surface of the top plate 320. The guide plate 330 is movably installed on the lower side of the top plate 320 through the cylinder 310. The upper die 340 is movably installed in the middle of the lower surface of the guide plate 330.

The buffer positioning assembly 200 includes an adjustable bottom rod 210 , a buffer cylinder 220 and an abutment rod 240 . The buffer cylinder 220 is welded to the upper end of the adjustable bottom rod 210 , and the abutment rod 240 is movably mounted to the upper end of the buffer cylinder 220 .

Please refer to Figures 1 and 2. The lower end of the adjustable bottom rod 210 is fixedly connected to the base plate 110 through nuts and washers. A plurality of fixed through holes corresponding to the adjustable bottom rod 210 are formed downwardly on the upper surface of the base plate 110. The setting of the adjustable bottom rod 210 enables the user to adjust the height of the entire buffer positioning assembly 200 according to actual production conditions.

As the first embodiment of the utility model, by setting an adjustable bottom rod 210, in actual use, when it is necessary to adjust the overall height of the buffer positioning assembly 200 to meet the corresponding stamping descent height requirement, the nut on the lower side of the adjustable bottom rod 210 can be screwed to adjust the height of the adjustable bottom rod 210, and then the height of the adjustable bottom rod 210 can be adjusted, and the height of the entire buffer positioning assembly 200 can be further adjusted to meet the stamping use requirements.

Please refer to FIG. 1 , FIG. 3 , and FIG. 4 . An inner cylinder 224 is disposed inside the buffer cylinder 220 . An outer cavity 222 is disposed between the outer wall of the inner cylinder 224 and the inner wall of the buffer cylinder 220 . The upper end of the outer cavity 222 is sealed.

An inner cavity 221 is provided inside the inner cylinder 224 . The upper end of the inner cavity 221 is open, and a plurality of communication holes 223 are radially opened outward at the lower end of the inner cylinder 224 .

The lower end of the inner cavity 221 is connected to the outer cavity 222 through a plurality of connecting holes 223. A return spring 250 is movably installed at the bottom of the inner cavity 221 of the inner tube 224. The abutment rod 240 includes a telescopic rod 241 and a docking joint 242. The setting of the connecting holes 223 can enable the oil in the inner cavity 221 to quickly enter the outer cavity 222 after being pressurized, and compress the air in the outer cavity 222 to achieve the purpose of buffering.

The lower end of the telescopic rod 241 is slidingly sealed and installed on the upper side of the inner cavity 221. The outer wall of the lower end of the telescopic rod 241 is sleeved with multiple sealing rings. The upper end of the telescopic rod 241 is integrally provided with a docking joint 242. The upper surface of the docking joint 242 is compounded with a buffer pad 243, which is a rubber plate.

Oil 1 is injected into the bottom of the inner cavity 221, and oil 2 is injected into the bottom of the outer cavity 222. The liquid level of oil 1 is the same as the liquid level of oil 2.

As the second embodiment of the present invention, in actual use, when the stamping assembly 300 pushes the upper mold 340 to stamp the lower mold 130 on the base 100, the guide plate 330 on the stamping assembly 300 will first contact the buffer pad 243 at the upper end of the abutment rod 240 during the downward movement. During the continuous downward pressure process, the buffer pad 243 will transmit the downward pressure impact force to the docking head 242 and the telescopic rod 241, and the entire abutment rod 240 will move downward synchronously. The lower end of the telescopic rod 241 quickly enters the inner cavity 221 of the buffer cylinder 220, thereby squeezing the compressed air contained in the inner cavity 221 between the upper end surface of the oil and the lower end of the abutment rod 240, and the compressed air in the inner cavity 221 will be The oil 1 at the bottom is quickly pressed into the outer cavity 222 through the connecting hole 223, and the oil 2 in the outer cavity 222 moves upward to squeeze the compressed air inside it. After the lower end of the telescopic rod 241 continues to move downward and compresses the return spring 250 in the inner cylinder 224 for a period of time, the entire downward pressing process is completed. The oil 1 and the return spring 250 in the inner cylinder 224 cooperate with the oil 2 and the compressed air in the outer cavity 222 to provide a relatively stable and effective buffer for the downward movement of the abutment rod 240, thereby making the upper mold 340 relatively stable during the stamping process with the workpiece, reducing the vibration and stress of the workpiece to be stamped and the fixture, and effectively avoiding the deformation and cracking of the workpiece after stamping.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
