Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] However, the existing stamping die uses a hydraulic rod to align the two dies, and the workpiece is pressurized and formed in the two dies. The formed workpiece does not fall off directly, but is attached to the surface of one of the fixtures, which is not conducive to demolding. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that a workpiece is press-formed in two dies, and the formed workpiece does not fall off directly but adheres to the surface of one of the clamps, which is not conducive to demoulding, and proposes a stamping die.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A stamping die comprises a bearing support, a fixed shell is fixedly connected to the bearing support, a support rod is sleeved in the fixed shell, a fixed plate is fixedly connected to the support rod, an electric push rod is fixedly connected in the fixed plate, an output end of the electric push rod is fixedly connected to a bracket, a screw is sleeved in the bracket, a push plate is fixedly connected to the screw, and a nut is threadedly connected in the screw.

[0007] Preferably, a positioning pin is threadedly connected in the fixing shell, and the positioning pin is threadedly connected to the supporting rod.

[0008] Preferably, a first mold is fixedly connected to the bearing support.

[0009] Preferably, a double-headed threaded rod is rotatably connected in the bearing support, a slider is threadedly connected to the double-headed threaded rod, the slider and the bearing support are sleeve-connected, a clamp is fixedly connected to the slider, and a motor is installed on the double-headed threaded rod.

[0010] Preferably, a transverse plate is fixedly connected to the bearing support.

[0011] Preferably, a right-angle plate is fixedly connected to the transverse plate, a hydraulic rod is installed in the right-angle plate, and the output end of the hydraulic rod is fixedly connected to the second mold.

[0012] Preferably, a guide rod is fixedly connected to the right-angle plate, and the guide rod is sleeve-connected to the second mold.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the support rod, fixed plate, electric push rod, bracket, screw, push plate and nut, when the first mold and the second mold complete the stamping of the workpiece, the electric push rod is started to drive the bracket to move, and the bracket drives the push plate to move horizontally through the screw, and the two push plates move horizontally and contact the first mold and the second mold respectively, so as to unload the molded workpiece attached to the first mold or the second mold. By changing the position of the screw in the bracket and using the nut to determine the use position of the screw, it is convenient for the push plate to fit the first mold or the second mold, so as to ensure the unloading effect of the molded workpiece;

[0015] 2. By setting up the double-headed threaded rod, slider, clamping plate and motor, start the motor to drive the double-headed threaded rod to rotate in the bearing support through the coupling. As the double-headed threaded rod rotates, the slider drives the two clamping plates to move toward each other along the top of the bearing support. The clamping plate pushes the workpiece to the middle position of the first mold, determines the stamping position of the workpiece, facilitates the stamping process on the workpiece, and ensures the forming effect of the workpiece.
