Description
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.
