The invention relates to a composite connecting system of a body cross beam and a supporting arm of a heavy numerically controlled screw press. The composite connecting system is characterized by comprising the body cross beam and a left supporting arm and a right supporting arm mounted on the body cross beam through a composite connecting mechanism; the composite connecting mechanism comprises aplurality of upper end cylindrical pins and a plurality of upper end flat keys mounted at the contact parts of the body cross beam and the upper end surfaces of the left supporting arm and the right supporting arm, a plurality of cross keys mounted at the contact parts of the body cross beam and the side faces of the left supporting arm and the right supporting arm, and a plurality of fastening bolts firmly connecting the body cross beam and the left supporting arm and the right supporting arm. The composite connecting system of the body cross beam and the supporting arm of the heavy numerically controlled screw press has multiple connections and is reliable to fix, and can be widely applied to the heavy numerically controlled screw press, in particular to a 125000 kN screw-slide block secondary balanced heavy numerically controlled screw press.
Description
technical field [0001] The invention relates to a composite connection system of a crossbeam and a support arm of a heavy-duty numerical control screw press machine body, which can be widely used in heavy-duty numerical control screw presses, especially in a 125000kN screw slider two-stage balanced heavy-duty numerical control screw press. Background technique [0002] The connection structure between the existing fuselage beam and the left support arm and the right support arm is only connected by bolts. In this connection mode, once the bolts and nuts are loose, the connecting parts will be loosened, resulting in the problem of cutting off the bolts, thus affecting the normal use of the equipment. Contents of the invention [0003] The object of the present invention is to provide a multi-connection, fixed and reliable heavy-duty numerical control screw press fuselage beam and support arm compound connection system. [0004] In order to achieve the above object, the hea...
