Description

Technical Field

[0001] The utility model belongs to the field of stamping dies, and particularly relates to a stamping and shaping die. Background Art

[0002] A stamping and shaping die is a tool for metal stamping processing. Its main function is to process metal sheets into parts with specific shapes through stamping technology. It usually consists of two parts: the upper die and the lower die of the die.

[0003] When the existing stamping and shaping die is used for stamping and processing a metal raw material plate, a general stamping die uses multiple guide rails to limit and assist the upper die. However, a single guide rail structure often causes damage to the sliding grooves on the upper die after long-term use, thereby affecting the smoothness of the upper die during use. Moreover, when the upper die is driven by a hydraulic structure to reset and move upward, it is not only easy for the upper die to shake and wear slightly during the stamping process, thus affecting the service life of the device.

[0004] Therefore, aiming at the problem that when the above-mentioned stamping and shaping die is used for stamping and processing a metal raw material plate, a single limiting structure is often difficult to provide efficient anti - auxiliary for the die, and the die is prone to wear after long - term use, a stamping and shaping die is developed. By adding multiple limiting auxiliary structures, reset auxiliary structures and sliding auxiliary structures to the stamping and shaping die, the effect of the device in stamping and shaping a metal die plate can be greatly improved, and the wear of the upper and lower dies during stamping and forming processing can be reduced. Summary of the Utility Model

[0005] In order to overcome the problem that when the stamping and shaping die is used for stamping and processing a metal raw material plate, the effect of its limiting structure in limiting and assisting the die is not good.

The upper end of the base is fixedly connected with the bottom platform. The four - corner edges of the upper end of the bottom platform are fixedly connected with limiting columns. The upper ends of the limiting columns are fixedly connected with the top platform. The outer wall of the limiting column is provided with sliding grooves that are equidistantly distributed around the limiting column for one week. An auxiliary spring is arranged on the outer wall of the limiting column. A guide rail is installed between the bottom platform and the top platform. The center of the upper end of the bottom platform is fixedly connected with the lower die. The upper die is arranged between the bottom platform and the top platform.

Four groups of sliders that are equidistantly distributed around the limiting groove for one week are fixedly connected to the inner wall of the limiting groove. Through - holes that are symmetric left and right are penetrated and opened at the upper and lower ends of the upper die.

[0007] Preferably, the four corners of the upper die can be limited multiple times through the guide rail cooperating with the limit posts and the chutes thereon, thereby improving the stability of the upper die and the lower die during stamping processing. The auxiliary spring assists the upper die to return upward after stamping to improve the stamping effect of the device on the metal raw material plate and the service life of the die.

[0008] Preferably, the inner wall of the through hole fits with the outer wall of the guide rail, and the inner wall of the limit groove fits with the outer wall of the limit post. During use, the through hole cooperating with the guide rail can provide preliminary limit assistance for the upper die, and the limit post and the limit groove can further provide limit assistance for the upper die to greatly improve the stability of the upper die during stamping processing.

[0009] Preferably, the upper die is adapted to the lower die, and the chute is adapted to the slider. During use, the chute and the slider can improve the smoothness of the up and down sliding displacement of the upper die along the outer wall of the limit post.

[0010] Preferably, the lower end of the auxiliary spring is fixedly connected to the upper four corners of the bottom platform, and the upper end of the auxiliary spring is fixedly connected to the lower four corners of the top platform. During use, the auxiliary spring can assist the upper die to return elastically to reduce the wear between the upper die and the lower die.

The upper end of the hydraulic frame is provided with an installation groove, and the lower end of the hydraulic frame is provided with a second groove body.

The connecting block is installed at the center of the upper end of the upper die. During use, the first groove body and the second groove body can provide limit assistance for the piston rod of the hydraulic cylinder to improve the stability of the hydraulic cylinder driving the upper die for stamping processing.

[0013] Preferably, the outer walls of the connecting block and the piston rod of the hydraulic cylinder fit with the inner walls of the first groove body and the second groove body. During use, the hydraulic cylinder can drive the upper die to stamp the metal raw material plate on the lower die.

[0014] Advantages of the present utility model:

[0015] 1. The four corners of the upper die can be limited multiple times through the guide rail cooperating with the limit posts and the chutes thereon, thereby improving the stability of the upper die and the lower die during stamping processing to improve the stamping effect of the device on the metal raw material plate;
