Technical Field

[0001] The utility model relates to the technical field of stamping of electric vehicle accessories, in particular to a stamping device for electric vehicle accessories. Background Art

[0002] Battery-powered scooters, also known as electric vehicles, are purely electric vehicles powered by batteries (DC, AC, series-excited, or externally excited). They have become widely popular in my country in recent years. The U-shaped lug is a key component in electric vehicle frames, connecting the frame to other components such as spring plates and shock absorbers. These lugs are often formed using a stamping press.

[0003] In the prior art, a stamping device generally punches the lug raw material into a U-shaped lug through the relative movement of a die and a punch. However, after the stamping is completed, the U-shaped lug often gets stuck on the outer wall of the punch, and it is necessary to use a tool to knock the U-shaped lug off. This makes it inconvenient to remove the material and easily causes product defects. Furthermore, the existing stamping device cannot locate the placement of the lug raw material, which easily causes the stamping position to deviate. Therefore, it is necessary to propose a stamping device for electric vehicle accessories to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a stamping device for electric vehicle accessories, which is convenient for taking out the formed U-shaped lifting ear and avoiding product defects, and is convenient for positioning the placement position of the lifting ear raw material to prevent deviation of the stamping position.

[0006] The upper end of the base plate is fixedly connected to a vertical plate, and a second electric telescopic rod is installed at the rear end of the vertical plate. The output end of the second electric telescopic rod passes through the vertical plate and is fixedly connected to a pusher frame located outside the punch. The front end of the pusher frame contacts the rear end of the lug raw material. The upper end of the base plate is fixedly connected to a collecting frame located at the connecting seat and the front end of the punch.

[0007] The upper end of the base plate is fixedly connected to a frame, and a hydraulic cylinder is installed on the upper end of the frame. The output end of the hydraulic cylinder passes through the upper end of the frame and is fixedly connected to a U-shaped die. The interior of the die is fixedly connected to a horizontal plate, and the lower end of the horizontal plate is fixedly connected to a compression spring. The lower end of the compression spring is fixedly connected to a push plate, and the upper end of the push plate is fixedly connected to a guide column that is sleeved inside the compression spring, passes through the push plate, and is slidably connected to the push plate.

[0008] In order to limit the downward movement of the push plate, as a preferred stamping device for electric vehicle accessories of the present invention, the outer wall of the guide column is fixedly connected with a limiting ring, the limiting ring abuts against the upper end of the horizontal plate, and the lower end of the push plate is in the same horizontal plane as the lower end of the die.

[0009] In order to improve the stability of the pusher frame movement, as a preferred punching device for electric vehicle accessories of the present invention, the left and right sides of the inner wall of the pusher frame are slidably connected to the left and right sides of the punch through sliders and slide grooves respectively.

[0010] In order to improve the stability of the push plate movement, as a preferred punching device for electric vehicle accessories of the present invention, the upper end of the push plate is fixedly connected to two sliding rods that penetrate the cross plate and are slidably connected thereto.

[0011] In order to prevent the die from shifting in the horizontal position, as a preferred punching device for electric vehicle accessories of the present invention, the upper end of the die is fixedly connected to two guide rods that penetrate the frame and are slidably connected to the frame.

[0012] In order to improve the stability of the positioning plate movement, as a preferred punching device for electric vehicle accessories of the present invention, the positioning plate is slidably connected to the upper end of the base plate through a slider and a slide groove.

[0013] In order to facilitate the installation and fixation of the device, as a preferred punching device for electric vehicle accessories of the present invention, both left and right ends of the base plate are fixedly connected with mounting plates.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The lug raw material is placed on the upper end surface of the punch, and the left end and rear end of the lug raw material are respectively in contact with the right end of the positioning plate and the front end of the push frame. Then, the positioning plate moves to the left for a certain distance, and the push frame moves backward for a certain distance, thereby positioning the lug raw material, and further achieving the purpose of preventing the deviation of the stamping position;

[0016] Then the hydraulic cylinder drives the die to move downward a certain distance, and then cooperates with the punch to stamp the ear raw material into a U-shaped ear, and the push plate will enter the inside of the die and compress the compression spring. After stamping, it moves upward to its original position through the die. In this process, the thrust of the compression spring on the push plate will exert downward pressure on the U-shaped ear, so that the U-shaped ear is always in contact with the punch until the die is located above the U-shaped ear, and then the U-shaped ear is pushed forward by the push frame until the front end of the push frame and the front end of the punch are in the same vertical plane. In this process, the U-shaped ear needs to be picked up by hand and then placed inside the collection frame, so as to facilitate the removal of the formed U-shaped ear and avoid product defects.
