Description

Technical Field

[0001] The present invention relates to the field of stamping technology, and specifically to a stamping device and a stamping method for the frame plates of electric bicycles. Background Art

[0002] Stamping is a forming process method that applies external forces to plates, strips, pipes, profiles, etc. by a press and a die, causing them to undergo plastic deformation or separation, so as to obtain workpieces with the required shapes and sizes. When processing the frame of an electric bicycle, it is necessary to perform stamping on the plates used for the frame.

[0003] For example, in the patent named: An Aluminum Alloy Precision Stamping and Forging Device Based on Bicycle Frame Processing, (Patent Application No.: CN202411089417.X), it is disclosed that a push die mechanism and a hydraulic rod are used to push the upper die downward, so that the upper die stamps an aluminum alloy plate on the lower die to form an aluminum alloy housing. When the upper die returns upward, the moving frame drives the lower die to move along the inside of the equipment base, causing the lower die to be misaligned with the upper die, facilitating the removal of the aluminum alloy housing. That is, when the upper die moves downward, the lower die can be reset. However, during the raw material feeding process, when the lower die and the raw material move to the bottom of the upper die, the position of the raw material is likely to change, and workers need to readjust the position of the raw material to perform the stamping work. Summary of the Invention

[0024] The present invention provides a stamping device and a stamping method for an electric bicycle frame plate. It has the following beneficial effects:

[0025] 1. For the stamping device and the stamping method for the electric bicycle frame plate, by setting a lifting mechanism and a protection mechanism, the feeding and protection of the plate are carried out. During the feeding process of the raw material of the existing stamping device, when the lower die and the raw material move to the bottom of the upper die, the position of the raw material is likely to change, and workers need to readjust the position of the raw material to carry out the stamping work. By using the lifting mechanism and the protection mechanism, the feeding work of the plate is completed outside the machine body, and the protection mechanism presses and escorts the plate to move under the upper die. During the feeding process of the plate, the plate is protected to prevent the situation that the position of the plate changes, so as to solve the above problems.

[0026] 2. For the stamping device and the stamping method for the electric bicycle frame plate, by setting a lifting mechanism, the height of the plate is controlled. By setting a bottom plate that can be lifted and moved outside the machine body, the lower die and the plate are placed, and the feeding area is set outside the machine body to increase the feeding space and facilitate the operation of workers. By setting a second backing plate that can be moved, it is convenient for workers to disassemble or install the lower die, so that workers can timely replace or clean the lower die. By setting the lifting rod to three different heights, the plate can be controlled to be at three different heights, and the feeding, stamping and discharging work of the plate can be completed in sequence.

[0027] 3. For the stamping device and the stamping method for the electric bicycle frame plate, by setting a protection mechanism, the plate is pressed and escorted. By adjusting the positions of the first adjusting column, the second adjusting column, the swivel joint and the cross plates, the three first adjusting columns are arranged staggeredly, and the strokes of the three first adjusting columns and the three second adjusting columns are adjusted, so that multiple cross plates contact the top of the plate, and the swivel joint deforms correspondingly, so as to press and fix the top of the special-shaped plate, avoid the situation that the position of the plate changes during the feeding process, and facilitate the position limitation of the plate with unconventional shape.

[0028] 4. The stamping equipment and stamping method for the frame plate of the electric bicycle complete the discharging work of the plate through the setting of the discharging mechanism. After the stamping work is completed, the special-shaped plate is large in size and irregular in shape, and it is difficult for workers to manually separate the plate from the lower die. By setting a plurality of card slots, according to the shape of the plate, the clamping rod is installed in the appropriate card slot, and the stroke of the clamping rod is adjusted so that the suction cup can contact the upper surface of the special-shaped plate, sucking and fixing the large-sized special-shaped plate after stamping, which is convenient for completing the discharging work of the plate.
