Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a self-lubricating stamping die. Background Art

[0002] A stamping die is a tool used for stamping metal sheets. It is usually composed of two parts, the upper and lower dies. The upper and lower dies move up and down through the punch press, applying a certain pressure to cause the metal sheet to deform under force, and finally completing the product of the desired shape.

[0003] When the upper mold reciprocates up and down to perform stamping work, the guide column can provide it with a certain degree of stability. However, the guide groove inside the guide column is prone to jamming due to repeated friction with the guide block, which causes the upper mold to shake slightly when moving up and down, thus affecting stability. Utility Model Content

[0004] The purpose of the utility model is to provide a self-lubricating stamping die. By installing guide columns on both sides of the upper die, the upper die will not deviate when pressure is applied from top to bottom, thereby ensuring its stability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-lubricating stamping die, comprising a workbench and a punching machine body, and also comprising guide columns and a buffer mechanism located on both sides of the upper end surface of the workbench, the punching machine body is fixedly connected to the upper end surface of the workbench, the guide columns and the buffer mechanism are fixedly connected to the upper end surface of the workbench, and a lower die is fixedly installed at the front end of the upper end surface of the workbench;

[0006] The front end surface of the punch body is connected with a connecting plate, the upper end surface of the connecting plate is installed with a hydraulic cylinder, the lower end of the connecting plate is provided with a mounting plate, the lower end surface of the mounting plate is fixedly installed with an upper mold, both sides of the mounting plate are fixedly connected with guide blocks, the upper end surface of the guide block is provided with an oil inlet, the side surface of the guide block is provided with a plurality of oil outlets, and a rubber bag is embedded in the guide block;

[0007] A guide groove is formed on the side surface of the guide column.

[0008] Preferably, the output end of the hydraulic cylinder passes through the connecting plate and is transmission-connected with the mounting plate.

[0009] Preferably, the guide block is slidably connected to the guide groove, and the mounting plate is slidably connected to the guide column via the guide block and the guide groove.

[0010] Preferably, a buffer block is fixedly mounted on the upper end surface of the buffer mechanism, and an extrusion block is fixedly connected to the upper end surface of the buffer block, and the size of the extrusion block corresponds to the size of the rubber bag.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] (1) The utility model provides a self-lubricating stamping die. When in use, when the mounting plate drives the upper die to move up and down, the guide blocks on both sides of the mounting plate slide synchronously with the upper die in the guide groove, thereby achieving a limiting effect, which can effectively prevent the upper die from moving up and down frequently and causing deviation, thereby increasing the overall practicality.

[0013] (2) The utility model provides a self-lubricating stamping die. When in use, when the lower die moves downward to the bottom, the extrusion block at the upper end of the buffer block will penetrate into the interior of the guide block and squeeze the rubber bag. The rubber bag is specifically made of a rubber material with a certain elasticity. After the rubber bag is subjected to the extrusion force, the lubricating oil inside it will spray from the oil outlet to the interior of the guide groove to lubricate the guide groove and the guide block, which can effectively avoid jamming of the mounting plate when it moves up and down, thereby preventing the lower die from shaking when it moves up and down, thereby ensuring the stability of the stamping movement.

[0014] (3) The utility model provides a self-lubricating stamping die. When in use, when the mounting plate drives the lower die to move downward to the bottom, the two sides of the lower surface of the mounting plate will touch the buffer block, thereby achieving a buffering effect, which can effectively prevent the lower die and the upper die from being too impacted and causing damage to the die, thereby increasing the overall practicality.

When the mounting plate 22 drives the lower mold 11 to move downward to the bottom, the two sides of the lower surface of the mounting plate 22 will touch the buffer block 41, thereby achieving a buffering effect, which can effectively prevent the lower mold 11 and the upper mold 221 from being damaged due to excessive impact. When in use, by setting the oil inlet 2221, it is convenient for the staff to inject lubricating oil into the rubber bag 2223, and the oil inlet 2221 is equipped with an end cover matching it, which can be closed after the oil filling is completed.

[0024] Furthermore, the output end of the hydraulic cylinder 211 passes through the connecting plate 21 and is transmission-connected with the mounting plate 22. When in use, by driving the hydraulic cylinder 211, the hydraulic cylinder 211 drives the mounting plate 22 and the upper mold 221 to apply pressure downward, thereby cooperating with the lower mold 11 to complete the stamping work.

[0025] Furthermore, the guide block 222 is slidably connected to the guide groove 31, and the mounting plate 22 is slidably connected to the guide column 3 through the guide block 222 and the guide groove 31. When the mounting plate 22 drives the upper mold 221 to move up and down, the guide blocks 222 on both sides of the mounting plate 22 slide synchronously with it inside the guide groove 31, thereby achieving a limiting effect, which can effectively prevent the upper mold 221 from frequently moving up and down and causing deviation.

[0026] Furthermore, a buffer block 41 is fixedly installed on the upper end surface of the buffer mechanism 4, and an extrusion block 42 is fixedly connected to the upper end surface of the buffer block 41. The size of the extrusion block 42 corresponds to the size of the rubber bag 2223. The buffer block 41 is specifically made of a rubber material with a certain elasticity. When the lower mold 11 moves downward to the bottom, the extrusion block 42 at the upper end of the buffer block 41 will penetrate into the interior of the guide block 222 and squeeze the rubber bag 2223. The rubber bag 2223 is specifically made of a rubber material with a certain elasticity. After the rubber bag 2223 is subjected to the extrusion force, the lubricating oil inside it will spray from the oil outlet 2222 to the interior of the guide groove 31 to lubricate the guide groove 31 and the guide block 222, thereby further increasing the stability of the up and down movement of the lower mold 11.

[0027] Working principle: The utility model is a self-lubricating stamping die. When in use, the hydraulic cylinder 211 first drives the mounting plate 22 and the upper die 221 to apply pressure downward, and cooperates with the lower die 11 to complete the stamping work. During the stamping process, the mounting plate 22 will be slidably connected with the guide column 3 through the guide block 222 and the guide groove 31, and then the mounting plate 22 and the upper die 221 can be limited to prevent deviation and increase the stability of their up and down movement. When the mounting plate 22 drives the lower die 11 to move downward to the bottom, The two sides of the lower surface of the mounting plate 22 will touch the buffer block 41, thereby achieving a buffering effect and preventing the mold from being damaged due to excessive impact force. At the same time, when the two sides of the lower surface of the mounting plate 22 touch the buffer block 41, the extrusion block 42 at the upper end of the buffer block 41 will penetrate into the interior of the guide block 222 and squeeze the rubber bag 2223. After the rubber bag 2223 is squeezed, the lubricating oil inside it will spray from the oil outlet 2222 to the interior of the guide groove 31 due to the extrusion force, which can further improve the stability of the up and down movement of the upper mold 221.
