Description

Technical Field

[0001] The utility model relates to the technical field of stamping of metal workpieces, in particular to a hydraulic die for a quadrangular pyramid-shaped stamping part. Background Art

[0002] Generally, a hydraulic drawing press can stamp metal plates into cylindrical and hemispherical shapes, but cannot stamp a quadrangular pyramid-shaped groove on the plate to manufacture a quadrangular pyramid-shaped workpiece to meet the needs of equipment production, so the practicability is relatively low. The quadrangular pyramid-shaped workpiece is shown in the attached specification Figure 6 , where label 20 is the raw material plate and label 21 is the quadrangular pyramid-shaped workpiece. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a hydraulic die for a quadrangular pyramid-shaped stamping part, which has the advantage of being convenient to stamp the plate into a quadrangular pyramid shape.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A hydraulic die for a quadrangular pyramid-shaped stamping part is provided with a hydraulic mechanism and a raw material plate. The hydraulic mechanism includes a workbench and a hydraulic punching plate. It is characterized in that it further includes a first mounting plate, the first mounting plate is fixed on the workbench surface, a punch is fixedly connected to the upper part of the first mounting plate, the periphery of the punch is of a quadrangular prism shape, the upper end of the punch is of a quadrangular pyramid shape, and the bottom surface of the punch is a rhombus. It further includes a bottom plate, the bottom plate is located above the first mounting plate, the bottom plate is provided with a first rhombus through hole, the punch is embedded in the first rhombus through hole of the bottom plate, and the punch is slidably connected with the bottom plate. An elastic member is arranged between the bottom plate and the first mounting plate. The hydraulic punching plate is fixedly connected with a second mounting plate, and the second mounting plate is fixedly connected with a template. The template is provided with a second rhombus through hole. Through the quadrangular pyramid-shaped end of the punch and the second rhombus through hole, a corresponding quadrangular pyramid-shaped workpiece can be pressed on the raw material plate.

[0006] By adopting the above technical solutions, the raw material plate is placed on the bottom plate to cover the opening of the bottom plate. The hydraulic punching plate drives the template to descend, the template presses the raw material plate, and the raw material plate drives the bottom plate to compress the elastic member, so that the raw material plate and the bottom plate descend, and a relative movement occurs between the bottom plate and the punch. The punch passes through the first rhombus through hole of the bottom plate and generates a force on the raw material plate. The template continues to descend, so that the punch and the raw material plate penetrate into the second rhombus through hole thereof, thereby pressing a quadrangular pyramid shape on the raw material plate for the manufacture of products and equipment, and increasing the practicability of the hydraulic drawing press.

[0007] Preferably, the first mounting plate and the second mounting plate are respectively fixed on the workbench and the hydraulic punching plate through a fixing mechanism. The fixing mechanism includes bolts, nuts, pressing blocks, screw rods, and a plurality of T-shaped grooves formed in the workbench and the hydraulic punching plate. There are two bolts, and the tails of the two bolts are respectively embedded in two T-shaped grooves of the hydraulic punching plate and are slidably connected to the hydraulic punching plate. There are two pressing blocks, each of which is provided with a sliding groove. The two bolts respectively pass through the sliding grooves of the two pressing blocks and are slidably connected to the pressing blocks. The nut is located below the pressing block and is threadedly connected to the bolt. The second mounting plate is located between the hydraulic punching plate and the pressing block and is in contact with the hydraulic punching plate and the pressing block.

[0008] With the above technical solution, tighten the nut to drive the pressing block to press the screw rod and the second mounting plate, thereby fixing the second mounting plate and the template on the hydraulic punching plate. Similarly, the bolt can be loosened to remove the template with a diamond hole and replace it with a mold of other shapes.

[0009] Preferably, the elastic member is a sponge pad. The sponge pad is located between the first mounting plate and the bottom plate. The upper and lower ends of the sponge pad are respectively fixedly connected to the bottom plate and the mounting plate.

[0010] With the above technical solution, the template presses the raw material plate, drives the bottom plate and the raw material plate to descend, compresses the sponge pad, and the bottom plate and the punch generate relative movement. The punch passes through the diamond through-hole one of the bottom plate and generates a force on the raw material plate. The template continues to descend, so that the punch and the raw material plate penetrate into its diamond through-hole two, thereby pressing out a quadrangular pyramid shape on the raw material plate. The template is separated from the bottom plate, and the sponge pad rebounds to drive the bottom plate to rise.

[0011] Preferably, two guide rods are fixedly connected to the first mounting plate and are respectively located on both sides of the punch. The two guide rods respectively pass through both sides of the bottom plate and are slidably connected to the bottom plate. The second mounting plate is provided with pin holes corresponding to the guide rods.

[0012] With the above technical solution, the template presses the bottom plate and drives the bottom plate to descend along the guide rods. At the same time, the guide rods penetrate into the pin holes to position the template and increase the stability of the movement of the bottom plate.

[0013] Preferably, the elastic member can also be a spring. The spring is located between the first mounting plate and the bottom plate. The upper and lower ends of the spring are respectively fixedly connected to the bottom plate and the mounting plate.

[0014] With the above technical solution,

[0015] Preferably, three cylindrical limiting blocks are integrally formed on the upper part of the bottom plate, and circular holes corresponding to the limiting blocks are formed on the template.

[0016] With the above technical solution, the raw material plate is placed on the bottom plate to cover the opening of the bottom plate. The edge of the raw material plate contacts the limit block, preventing the raw material plate from moving on the bottom plate and affecting stamping. When the template presses the bottom plate, the limit block moves in and out of the round hole, so that the template can press the raw material plate. Brief Description of the Drawings

A plurality of T-shaped grooves 10 are provided on the bottom surface of the hydraulic punching plate 2 and the tabletop of the workbench 1. The fixing mechanism includes bolts 11, pressing blocks 12 and screw rods 13. There are two bolts 11.
