Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to an automatic positioning and guiding device for stamping dies. Background Technology

[0002] Stamping dies are tooling devices that use a press to apply pressure to sheet metal, causing it to separate or plastically deform, thereby obtaining the desired parts. Stamping dies are widely used in automobile manufacturing, electronics, home appliances, aerospace and other fields, and have an irreplaceable position in the entire manufacturing industry. Stamping dies are usually composed of an upper die and a lower die. The upper die is fixed on the slide of the press, and the lower die is fixed on the worktable. During operation, the material is fed between the dies. When the upper die descends, the material is stamped by the punch to form the required shape. When the upper die rises, the stamped part is ejected by the ejection mechanism, and the waste is removed by the unloading mechanism.

[0003] The following problems exist: conventional stamping dies only have processing functions. Operators need to constantly put their hands into the closed area of ​​the die in order to move materials, which poses a great safety hazard. At the same time, it is impossible to achieve continuous automatic entry and positioning of parts. Utility Model Content

[0008] A side plate is fixedly connected to one end of the top of the workbench, and an outer tube runs through the side plate. A forward and reverse motor is fixedly connected to one end of the inner wall of the outer tube.

[0009] As a further description of the above technical solution:

[0010] A wireless control module is fixedly connected to one end of the outer wall of the reversible motor, and a threaded rod is rotatably connected to the movable end of the reversible motor.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the threaded rod is threadedly connected to an inner tube, the outer wall of the inner tube is slidably connected to the inner wall of the outer tube, and one end face of the inner tube is fixedly connected to the center of one side of the outer wall of the push plate.

[0013] As a further description of the above technical solution:

[0014] The top of the workbench has a through square hole at the other end, and a hollow ring is fixedly connected to the bottom of the inner wall of the square hole.

[0015] As a further description of the above technical solution:

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: When the forward and reverse motor drives the threaded rod to rotate, the inner tube can move back and forth on the outer wall of the rotating threaded rod, and at the same time, the push plate will slide back and forth on the top surface of the worktable. During the sliding process of the push plate, not only can the inner tube be prevented from rotating, but the material plate can also be pushed. Therefore, the operator does not need to manually move the material to the stamping area. By setting a push spring, the baffle can be pushed upward. By setting a baffle, the material plate pushed to the bottom of the stamping block can be intercepted, thereby achieving the effect of automatic positioning. With the extrusion of the push plate, the material plate can be fixed, which not only improves the safety of the entire stamping die, but also improves the efficiency of the stamping work.
