Abstract
The utility model relates to a bottom transmission press machine structure within the technical field of press machines, wherein the bottom transmission press machine structure is low in gravity, and stable and reliable in transmission. The bottom transmission press machine structure comprises a base, a bearing plate and a top plate. The bearing plate is fixed on the upper side of the base; the upper side of the bearing plate is fixed with the top plate; side plates are vertically placed on two sides of the base; two side plates are coaxially provided with supporting holes used for horizontally installing a bent axle; and a sliding block mechanism is placed on the upper portion of the bent axle and is connected with the bent axle in a transmission mode through a bottom connecting rod mechanism. In the prior press machine transmission mechanism, a crank connecting rod mechanism drives a sliding block to conduct stamping motion from the upper side of the sliding block. However, transmission components of a press machine of the bottom transmission press machine structure are mainly centralized on the base on the lower portion of a machine tool, and the gravity of the body of the integral machine is obviously reduced. Therefore, the bottom transmission press machine structure is balanced and reliable in transmission, high in transmission accuracy, good in vibration-proof performance and small in transmission noise, improves vertical stiffness of the whole machine, reduces energy consumed because of deformation of the body of the machine and improves energy usage ratio of the machine tool.
