Automatic waste material removal device for punched strip toothed mold

Abstract

This utility model relates to an automatic waste discharge device for a punching die with a tooth-removing mold, including a lower template and a movable seat. The lower template has a punching groove with an opening on its lower surface. The bottom of the punching groove has a through hole extending to the surface of the lower template. A boss is formed on the movable seat, which is located in the through hole. The movable seat is located in the punching groove and can move up and down, with a maximum downward distance that can be set. A discharge hole is formed on the movable seat, which passes through the boss and the movable seat vertically. During punching, the ejector rod is a punching die on the upper mold. A protrusion is also provided on the lower surface of the ejector rod, which is adapted to the discharge hole. The ejector rod abuts against the steel plate, causing the steel plate to deform and extend into the through hole. This causes the boss and the movable seat at the through hole to move down. After moving down to the maximum downward distance, the ejector rod continues to move, and the protrusion extends into the discharge hole. The protrusion and the discharge hole exert a shearing force on the steel plate, cutting the punched area of ​​the steel plate, and the waste is discharged from the discharge hole.

Description

Technical Field

[0001] This utility model belongs to the field of steel plate processing mold technology, specifically relating to an automatic waste discharge device for a punching mold with tooth extraction. Background Technology

[0002] Currently, punching dies and tooth-removing dies are operated separately. First, the steel plate is punched, and then the punched area is removed. This setup requires two sets of dies and has low production efficiency. Therefore, integrated punching and tooth-removing dies have emerged in the market. However, when using this new equipment, it was found that because the punching and tooth-removing processes are carried out simultaneously, the existing dies cannot remove waste material in time. Under prolonged operation, this may lead to tooth-removing failure. To solve this problem, this solution was developed. Utility Model Content

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, during punching, the ejector rod is a punching die on the upper mold, and a protrusion is provided on the lower surface of the ejector rod. The protrusion is adapted to the discharge hole. The ejector rod abuts against the steel plate, causing the steel plate to deform and extend into the through hole.

[0021] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0022] The mold mentioned in this solution also includes an ejector pin 4, the end of which is provided with a protrusion 41, and the edge of the end of the ejector pin 4 is formed with an arc-shaped chamfer.

[0023] like Figures 1-3 As shown, this embodiment provides an automatic waste removal device for a punching die with tooth extraction, including a lower template 1, a movable seat 5, a support partition 2, a lower die base 3, and a reset assembly 6.

[0024] The lower template 1, supporting partition 2, and lower mold base 3 are arranged sequentially from top to bottom. The lower template 1 has a stamping groove with the opening located on the lower surface of the lower template 1. The bottom of the stamping groove has a through hole extending to the surface of the lower template 1. A boss 53 is formed on the movable base 5, which is located in the through hole. The movable base 5 is located in the stamping groove. A discharge hole 531 is formed on the boss 53, which is adapted to the protrusion 41. Specifically, the movable base 5 includes a base body 51 and a forming post 52, with the boss 53 disposed on the upper surface of the forming post 52. The forming column 52 passes vertically through the base 51 and is engaged with the base 51. The base 51 has a mounting hole in the middle and two locking holes on the side wall. The two locking holes are located on both sides of the mounting hole and partially overlap the mounting hole in the projection of the vertical plane. The forming column 52 has locking notches on both sides. The forming column 52 is located in the mounting hole and is fixed by a locking block passing through the locking hole and the mounting hole and locking into the locking notch. This design allows the movable base 5 to be produced and assembled more easily.

[0025] The forming column 52 has a discharge hole 531 that runs vertically through it. The discharge hole 531 includes a vertical section 5311 and a tapered end 5312. The vertical section 5311 is located above the tapered section. The diameter of the tapered section increases from top to bottom. The support partition 2 and the lower mold base 3 have dropping holes corresponding to the discharge hole 531. With this top-small and bottom-large arrangement, waste material can be smoothly discharged from the discharge hole 531.

[0026] The support partition 2 is located below the lower mold plate 1. There is a moving space between the movable seat 5 and the support partition 2. The height of the moving space is the height of the tooth extraction. The reset assembly 6 is used to reset the movable seat 5. Specifically, the reset assembly 6 is installed on the lower mold base 3. The reset assembly 6 includes a reset rod 61 and a reset elastic body 62. The reset elastic body 62 is a spring. A contact plate is provided at the bottom of the reset rod 61. The support partition 2 forms a through hole. The contact plate is located below the through hole. The reset rod 61 passes through the through hole and abuts against the lower surface of the movable seat 5. The reset elastic body 62 is located below the contact plate. There are four reset rods 61. The four reset rods 61 are arranged in a ring at intervals along the axis of the protrusion 41. In this scheme, a single reset elastic body 62 drives the four reset rods 61 together.

[0027] A discharge channel 31 is provided below the lower mold base 3. The discharge channel 31 is connected to the discharge hole. Waste material in the discharge channel 31 can be discharged by manual cleaning, water flow or air blowing. The discharge channel 31 can be formed by raising the lower mold base 3 and surrounding it, or it can be opened directly below the lower mold base 3.

[0028] Preferably, a discharge conveyor belt 7 can also be provided for discharging materials. The discharge conveyor belt 7 is located below the discharge hole, and the waste material falls into the discharge conveyor belt 7 and is discharged directly.

[0029] In this scheme, during the tooth extraction process, the steel plate is pushed downward by the protruding post 41 on the push rod 4. The opening of the steel plate and the discharge hole 531 form a shearing force to cut the tooth extraction area of ​​the steel plate. The cut waste falls into the discharge hole 531 and is discharged.
