In manufacturing specifications and schedule a lot of fine planer puncher, only reduce its schedule frequency, reduction ratio and improve transmission gear geometric series, and limit the fine longmen punch stamping tool to promote the efficiency of production, in order to promote this limit, only to structure to carry out the modification, fine and sale on the market at present large cargo capacity of longmen punch modification has the structure of the punching machine to complex and huge, led to the later period maintenance, the maintenance of the application of multifarious.

For the fine processing planer puncher itinerary at low frequency, structure and complex not easy maintenance difficulties, for large precise planer puncher chose the new structure, improved the new large cargo capacity of 65 t high speed punch the shell with big gear, engine crankshaft, connecting rod and the guide rail slider, support the big gear axle shaft pin is built on the shell, engine crankshaft and connecting rod fixed connection, connecting rod and the guide rail slider hinge, within the shell with a crank and rocker, on the big gear is equipped with a connecting rod pin, one end of the crank and connecting rod pin fixation, the other end of the crank and rocker according to place at the end of the pin is pick up, The other end of the swing rod is fixedly connected with the engine crankshaft.

Fine punch Longmen punch has great requirements in the field of mass production technology in China, especially in the field of wiring terminals, EI pieces, stator motor rotor and other hardware production and manufacturing has a very great future. The production process and structure of fine Longmen Punch also have improved interior space. High-speed precision Punch Factory will persevely carve and carve to ensure the technical strength and equipment quality of each fine Longmen Punch.
