Abstract

The utility model discloses a transmission mechanism for a four-point load punching machine, which is characterized by comprising two juxtaposedly and horizontally arranged crank type crank shafts with force application points at two ends; and a synchronous transmission device is arranged between the two crank shafts. Because the two juxtaposedly and horizontally arranged crank type crank shafts with the force application points at two ends replace the traditional eccentric gear structure, the transmission mechanism for the four-load punching machine has the advantages of simple structure, convenient processing, low cost and small structure and is suitable for middle and small-sized punching machines.

Description

A kind of transmission mechanism of four point load punch presses

Technical field

The utility model relates to a kind of transmission system of punch press, relates in particular to a kind of transmission mechanism of four point load punch presses.

Background technology

In recent years, along with the maximization of household appliances such as TV, refrigerator, the demand of the punch press of light load, large working area increased, and must guarantee the machining accuracy of the product made with large working area, therefore to the increase in demand of medium and small four point load punch presses.And because the transmission mechanism of present four point load punch presses generally all adopts the eccentric gear formula, its complex structure and maximization, the manufacturing cost height generally all is used on the large-scale punch press at present, and also can't popularize on medium and small punch press.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple in structure, low transmission mechanism that is suitable for use in four point load punch presses on the medium and small punch press of cost.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of transmission mechanism of four point load punch presses, comprise that two ends have two horizontally disposed side by side crank-type bent axles of the point of application, are provided with synchronous transmission device between described two bent axles.

Described synchronous transmission device comprises power transmission shaft, first transition axis and second transition axis, be set with drive on the described power transmission shaft, be set with the breast wheel and first idle pulley on described first transition axis, be set with second idle pulley on described second transition axis, described drive is meshed with described breast wheel, described first idle pulley and the described second idle pulley synchro-meshing, described first idle pulley is meshed with first driven pulley on fixedly installing therein a bent axle, described second idle pulley is meshed with second driven pulley on being fixedly installed on another root bent axle, and described first driven pulley equates with the number of teeth of described second driven pulley.

Compared with prior art, the utility model has the advantages that owing to have the alternative traditional eccentric gear formula structure of two horizontally disposed side by side crank-type bent axles of the point of application with two ends, make the whole transmission mechanism of four point load punch presses simple in structure, easy to process, cost reduces, and structure diminishes, and is adapted at using on the medium and small punch press.
