Description

Bicycle chain wheel punching machine

Technical Field

The utility model belongs to the technical field of bicycle chain wheel punching, and particularly relates to a bicycle chain wheel punching machine.

Background

The bicycle is mainly characterized in that the bicycle is in a middle shaft shape, the middle shaft shape mainly comprises three shapes, namely a hollow shape, a spline shape and a square hole, wherein the spline shape is the best in connection strength, so most hollow crankshafts are actually connected in a spline connection mode, only shafts are integrated on the crankshafts, the weight is lighter than that of the splines, and the cost is high. The square hole is an old-fashioned linking mode, and has the defects that a bearing is small, bearing capacity is weak, weight is heavy, a crank is easy to deform, transmission is inferior to splines, and the advantage is low in price, for example, a bicycle chain wheel 100 shown in fig. 6 is a disc-shaped part, a hole arranged in the center of the bicycle chain wheel is often connected with a bicycle crank 104, a gear ring 101 arranged on one side of the circumference of the chain wheel 100 is used for being meshed with a bicycle chain to transmit power, large circular through holes 102 uniformly arranged in an annular shape on the chain wheel 100 are used for saving materials, the weight of the chain wheel 100 is reduced, the use strength of the chain wheel 100 can be ensured, and the water drop-shaped through holes 103 can further reduce the weight of the chain wheel 100 and save materials on the premise of ensuring the normal use of the chain wheel 100.

Because the kind of hole is more on the bicycle chain wheel, so the piercing press is when punching a hole to the bicycle chain wheel, because a chain wheel needs the hole of multiple shape, so the piercing press can leave a great deal of waste material that becomes certain shape after punching a hole to the chain wheel, this type of waste material all can be through dissolving and chemical treatment recovery and reuse again, but different punching hole shapes, the fashioned waste material size shape that leaves over is also different, this just causes very easily when dissolving the processing to the waste material, the waste material dissolving treatment's of equidimension speed is also different, can influence subsequent processing.

SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is: the bicycle chain wheel punching machine is capable of collecting and crushing waste generated by punching while punching, and the volume of the waste after crushing is smaller and the subsequent treatment is more convenient.

In order to achieve the technical purpose, the technical scheme adopted by the utility model is as follows:

a bicycle chain wheel punching machine comprises a punching machine body, wherein a punching working groove is formed in the middle of the punching machine body, an installation groove is formed in the lower side of the punching machine body, a workpiece fixing table is installed on the upper end face of the punching working groove, three blanking ports are uniformly arranged on the punching machine body and respectively penetrate through the punching working groove and the installation groove, three blanking through holes corresponding to the three blanking ports in position one to one are formed in the workpiece fixing table, a crushing box is installed inside the installation groove, openings matched with the three blanking ports are formed in the upper end face of the crushing box, two gear shafts are arranged inside the crushing box in parallel, one ends of the two gear shafts extend out of the crushing box and the punching machine body and are respectively fixedly provided with gears, the two gears are meshed with each other, and the parts of the two gear shafts, which do not extend out of the crushing box, are respectively provided with crushing gears, the two crushing gears assembled by the gear shafts are meshed with each other, the motor is installed on one side of the punching machine body, the output shaft of the motor is in transmission connection with one of the gears, and the waste collection assembly is installed on the lower side of the crushing box.

When using the piercing press, place the part on the work piece fixed station earlier, start the piercing press and carry out work after that, because the piercing press is when punching a hole, it leaves the clearance to need work piece and supporting part, so after finishing punching a hole, the waste material that produces of punching a hole also can fall down from the clearance that needs work piece and supporting part, so after finishing punching a hole the waste material can fall into among the broken case from the blanking through-hole, start motor when punching a hole, the motor drives two gear shafts in the broken case rotatory, a plurality of crushing component intermeshing of two gear shafts, carry out the breakage with the waste material.

The waste collection assembly includes a waste collection drawer slidably mounted to the crushing bin at a lower side of the two gear shafts and a handle mounted to a front face of the waste collection drawer. After the waste is crushed, the waste falls downwards and falls into the waste collection drawer, after the waste is accumulated to a certain degree, the handle is held by hands to pull outwards, the waste collection drawer can slide out of the crushing box, after the crushed waste is treated, the handle can be held by hands, and the waste collection drawer is inserted into the crushing box again.

A motor protection box matched with a motor is installed on one side of the punching machine body, and the motor protection box is hinged with a first sliding door. The motor protection box can play the effect of a protection for the motor, prevents to be destroyed by external force, and when wanting to adjust motor protection box inside, just need open first sliding door and just can accomplish, it can to close first sliding door again after the adjustment finishes.

Four supporting platforms are evenly installed on the lower end face of the punching machine body. The support platform can play a stable supporting role for the punching machine body.

A tool box is installed on one side of the punching machine body, and a second sliding door is hinged to the tool box. Because the punching machine may require the use of a large number of tools for adjusting the parameters of the punching machine during use, the installation of a tool box facilitates the storage of tools in the tool box or the like, which may be opened and closed by a second sliding door.

An observation window is arranged on the front side of the crushing box. The crushing condition inside the crushing box can be observed conveniently.

Two blanking guide plates are obliquely arranged on the upper side of the crushing box. Therefore, the fallen waste can be guided to the position where the crushing teeth are meshed and crushed in the crushing box through the blanking guide plate, so that the waste is prevented from falling to the corner position of the crushing box and cannot be crushed.

The waste material generated by the punching machine can be collected when the punching machine works, the collected waste material can be crushed when the punching machine works, the crushed waste material has smaller volume and saves loading space, and the size of the crushed waste material is almost the same because the volume of the crushed waste material is the volume after crushing when the crushed waste material is treated, so that the dissolving speed is almost the same during dissolving treatment, the working efficiency can be enhanced, and the working time can be saved.
