Technical Field

[0001] The utility model relates to the technical field of bicycle processing, in particular to a punching machine for bicycle processing. Background Art

[0002] The bicycle hub needs to be drilled before use so that the spokes of the bicycle can be plugged and connected between the hub and the wheel hub to maintain the support of the wheel hub.

[0003] In the existing punching process of the bicycle hub, it is necessary to punch a hole at one end of the hub first, and then change the direction of the hub to punch a hole at the other end, so that the punching process of the hub needs to be completed twice, resulting in low processing efficiency.

[0004] The existing punching machine for processing bicycle hubs has the following drawbacks: during the punching process of the hub original, only one end of the hub original can be punched first, and then the hub original can be changed to punch the other end, which brings inconvenience, resulting in many processing steps and long processing time. To this end, we propose a punching machine for bicycle processing. Summary of the invention

[0005] The main purpose of the utility model is to provide a punching machine for bicycle processing, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

The die groove is penetrated through the punching platform of the punching machine, the fixed die is installed at one end in the die groove by bolts, and the movable die is located at the other end in the die groove. A hydraulic push rod is installed in the punching platform of the punching machine by bolts, and the output end of the hydraulic push rod is bolt-mounted and connected with the back bolt of the movable die. The covering parts of the fixed die and the movable die are both provided with corresponding hub cavities, and the top and bottom of the hub cavity are evenly spaced with punches, and the top and bottom of the hub cavity are respectively provided with corresponding punches, and the punches are provided with hole heads corresponding to the punches.

[0008] Furthermore, the top and bottom of the die groove are respectively provided with cylinders corresponding to multiple positions of the punches, the cylinder bodies of the cylinders are respectively mounted and connected to the frame of the punch press by bolts, and the output ends of the cylinders are respectively mounted and connected to the punches at corresponding positions.

[0009] Furthermore, guide rods are respectively installed on both sides of the back of the movable mold away from the hydraulic push rod through bolts, and the guide rods are inserted through the punching platform of the punching machine.

[0010] Furthermore, positioning rods are respectively welded to both sides of the covering end of the movable mold, and positioning holes corresponding to the positioning rods are respectively opened on both sides of the covering end of the fixed mold.

[0011] Compared with the prior art, the utility model has the following beneficial effects: through the components consisting of a punch press, a die groove, a fixed die and a movable die, a punch press structure is provided for the bicycle hub which can perform punching processing on both ends of the hub at the same time, so that both ends of the hub original component can be punched at the same time, which greatly improves the efficiency of hub processing and solves the inconvenience caused by the existing hub original component during the punching processing, that is, during the punching processing, only one end of the hub original component can be punched first, and then the direction of the hub original component is changed to punch the other end, resulting in the inefficiency of having many processing steps and a long processing time.
