Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a cutting die for stamping. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). A stamping die consists of a fixed part and a moving part. The fixed part is fastened to the press table using pressure plates, bolts, etc.; the moving part is generally fastened to the press slide. Types of stamping dies include blanking dies, drawing dies, bending dies, flanging dies, and hemming dies, and they are widely used in various fields, including automotive, electronics, and daily hardware.

[0003] When processing alloy cutters, stamping dies are required. However, existing cutter processing stamping dies make it inconvenient to change the cutter head, and the base of the stamping die cannot be adjusted, which limits its use.

[0004] Therefore, we propose a cutting tool for processing stamping dies. Utility Model Content

[0005] The main purpose of this utility model is to provide a cutting die for stamping. By designing a first punch and a second punch, the stamping die can select the first punch or the second punch to be used according to different processing requirements, so that the stamping die can meet different processing requirements. By using a slider located at the bottom of the die holder, the die holder can be moved on the upper surface of the base plate until the die holder is moved to the designated position, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A cutting die for stamping includes a stamping device, a frame, a stamping hydraulic cylinder, a die base, and a base plate. The stamping device is mounted on the upper surface of the base plate. The die base is slidably connected to one end of the upper surface of the base plate. The die base and the stamping device are arranged at a right angle. The top of the stamping device is movably connected to the frame. The top of the frame near the die base is fixedly connected to the stamping hydraulic cylinder. The bottom of the stamping hydraulic cylinder is connected to a first punch and a second punch respectively through a punch rod.

[0008] The top of the mold base is provided with a placement cavity for placing workpieces. Two opposing placement plates are fixedly connected to the inner wall of the placement cavity. A stamping channel is provided between the two placement plates. A push plate for defining the position of the workpiece is provided in the placement cavity. The two ends of the push plate are slidably connected to the inner walls on both sides of the placement cavity. The push plate is located on the upper end face of the placement plates. A lead screw is threaded to the upper part of one end of the mold base. A groove for picking up the workpiece is provided at the end of the mold base away from the lead screw. The groove communicates with the stamping channel.

[0009] By adopting the above technical solution, the design of the threaded column facilitates the installation and removal of the second punch on the mounting plate, allowing the second punch to be flexibly disassembled. The top of the first punch is threadedly connected to the bottom of the punch rod, allowing the first punch to be flexibly disassembled and replaced. Through the design of the first and second punches, the stamping die can select the first or second punch to be used according to different processing requirements, so that the stamping die can meet different processing needs.

[0010] Specifically, the bottom end of the punch rod is provided with a threaded groove, the top end of the first punch is threadedly connected to the bottom end of the punch rod, and the first punch is located directly above the mold base.

[0011] Specifically, two sets of the second punches are arranged in parallel. A limit plate is fixedly connected to the top of the second punch, and a threaded post is fixedly connected to the center of the top of the limit plate.

[0012] Specifically, the top of the threaded column passes through both ends of the mounting plate and is threadedly connected to the nut. A threaded mounting seat adapted to the bottom end of the punch is provided at the center of the upper surface of the mounting plate. The second punch is located above the die base.

[0013] Specifically, handles are fixedly connected to both ends of the mold base on the side away from the stamping device, and fixing ears are fixedly connected to the lower part of both ends of the mold base. The fixing ears are fixedly connected to the upper surface of the base plate by fixing bolts.

[0014] Specifically, a slide bar is fixedly connected to the bottom end of the mold base along the maximum length direction, and a slide groove adapted to the slide bar is provided on the upper surface of the base plate away from the stamping device.

[0015] The beneficial effects of this utility model are:

[0016] (1) The cutting die for stamping described in this utility model is designed with a threaded column to facilitate the installation and removal of the second punch on the mounting plate, so that the second punch can be flexibly removed. The top of the first punch is threadedly connected to the bottom of the punch rod, so that the first punch can be flexibly removed and replaced. With the design of the first punch and the second punch, the stamping die can select the first punch or the second punch to be used according to different processing requirements, so that the stamping die can meet different processing requirements. With the design of the cavity and push plate at the top of the die base, the die base can limit the position of different workpieces, further improving the practicality of the device.

[0017] (2) The cutting die for stamping described in this utility model places the workpiece to be processed in the placement cavity at the top of the die base, and turns the lead screw. Through the threaded engagement between the lead screw and the top of the die base, the lead screw can push the push plate towards the workpiece until the workpiece is fixed in the placement cavity. Through the slide bar at the bottom of the die base, the die base is moved on the upper surface of the base plate until the die base is moved to the designated position. This solves the problem that the base of the stamping die in the prior art cannot be adjusted. One end of the fixing bolt passes through the mounting ear and is threadedly connected to the base plate. The stamping hydraulic cylinder can push the first punch and the second punch downward through the punch rod. The purpose of stamping the workpiece can be achieved through the first punch or the second punch. With the cooperation of the above structure, it has the advantage of simple operation.
