Description

Technical Field

[0001] The utility model relates to the field of punching dies, in particular to a punching die for bicycle accessories. Background Art

[0002] A bicycle, also known as a pedal bike or a bicycle, is usually a small two-wheeled vehicle for land travel. During the processing of bicycle accessories, it is necessary to punch holes on the surfaces of different accessories. Generally, a punching die is used to perform punching operations on the accessories so as to connect and fix multiple spare parts through through holes.

[0003] In the prior art, when punching general spare parts, it is necessary to put the accessories outside the supporting die with a corresponding shape to support the accessories, thereby preventing the accessories from deforming during punching. However, although the accessories are the same during processing, the punching positions are different. Since the hole positions of the supporting die are fixed, it cannot be used for punching operations at different positions. At this time, it is necessary to replace the supporting die. Frequent replacement will affect the processing efficiency and increase the processing cost. Therefore, it is necessary to improve a punching die for bicycle accessories to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the problem that the hole positions of the supporting die are fixed and it cannot be used for punching operations at different positions. At this time, it is necessary to replace the supporting die, and frequent replacement will affect the processing efficiency.

[0005] The technical solution of the utility model is: a punching die for bicycle accessories, including a fixed die base, and further including a threaded rod, a slider, a connecting block, a backing plate and a punching mechanism. The punching mechanism is arranged on the top of the fixed die base. The threaded rod is arranged on the top of the fixed die base. The slider is threadedly connected to the outside of the threaded rod. The top of the slider is fixedly connected to the connecting block. The top of the connecting block is fixedly connected to the backing plate. By rotating the threaded rod to drive the backing plate to adjust its position, the backing plate can be flexibly adjusted according to the punching position of the workpiece.

[0006] Preferably, put the accessories outside the cushion block, and the threaded rod drives the backing plate to move, thereby adjusting the position of the backing plate to meet the punching operations at different positions. Moreover, the backing plate and the connecting block can discharge the waste materials from punching. The hydraulic press drives the moving die base to descend, and is buffered by the spring. Then, the punch cooperates with the backing plate to perform punching, and the installation position of the mounting plate can be adjusted through the threaded hole of the moving die base.

[0007] As a preference, a material discharging groove is formed inside the connecting block, and a cutting hole is formed inside the backing plate, and the positions of the cutting hole and the material discharging groove correspond to each other, so that the waste materials from punching can fall into the inside of the cushion block through the cutting hole and the material discharging groove for subsequent cleaning.

[0008] Preferably, an installation block is fixedly connected to the top of the fixed mold base. A cushion block is movably connected inside the installation block. A first bolt is threadedly connected inside the installation block. The first bolt is movably connected inside the cushion block. A positioning plate is fixedly connected to the top of the cushion block. A limiting plate is fixedly connected inside the positioning plate. A hexagonal rotating block is rotatably connected inside the limiting plate. A threaded rod is rotatably connected between the cushion block and the limiting plate. The hexagonal rotating block is fixedly connected to the front of the threaded rod. A slider is slidably connected inside the limiting plate. A backing plate is slidably connected inside the cushion block. The position of the backing plate can be adjusted by the threaded rod to meet the punching requirements at different positions.

[0009] Preferably, a chute is provided at the corresponding position of the cushion block for the backing plate, and the backing plate slides inside the chute. The backing plate is limited by the chute to prevent it from detaching from the cushion block.

[0010] Preferably, a through hole is provided at the corresponding position of the cushion block for the first bolt, and the first bolt passes through the through hole. The cushion block is installed inside the installation block through the through hole of the cushion block, which is convenient for replacing the cushion block.

[0011] Preferably, the punching mechanism includes a column, which is fixedly connected to the top of the fixed mold base. A sliding sleeve is slidably connected to the outside of the column. A connecting ring is fixedly connected to the outside of the sliding sleeve. A spring is fixedly connected between the connecting ring and the fixed mold base. A moving mold base is fixedly connected to the top of the sliding sleeve. A second bolt is threadedly connected inside the moving mold base. The outside of the second bolt is movably connected to an installation plate. A punch is fixedly connected to the bottom of the installation plate. The moving mold base is driven to descend by a hydraulic press. While being buffered by the spring, the punch punches the fitting.

[0012] Preferably, ten threaded holes are provided inside the moving mold base, and the ten threaded holes are arranged in sequence from front to back inside the moving mold base. The position of the installation plate can be arbitrarily positioned through the threaded holes, which is convenient for processing at different positions.

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

[0014] 1. By rotating the threaded rod to adjust the position of the backing plate, the position of the backing plate can be adjusted according to the size and position of the punching required for the tool fitting. Thus, the fittings with the same size but different punching positions can be fixed by the cushion block, without the need to frequently replace the cushion block, effectively improving the work efficiency.

[0015] 2. The moving mold base is limited by the column and the sliding sleeve, so that the moving mold base moves linearly up and down without deviation. And it is buffered by the spring to prevent damage caused by large impact. Moreover, the position of the punch is adjusted through the threaded holes of the moving mold base, which is convenient for adjusting the punching position of the punch. Description of the Drawings
