Adjustable tight pressing device for forming mill

Abstract

The invention relates to an adjustable tight pressing device for a forming mill. The adjustable tight pressing device for the forming mill is composed of a guide rail seat, a hinge assembly component, a hoop component, a tackle component and a hand wheel component, and the hinge assembly component comprises a right-hand thread supporting seat, a left-hand thread supporting seat, a screw tightening rod seat, a tight pressing rod seat and four chain rods, wherein the right-hand thread supporting seat and the left-hand thread supporting seat are correspondingly arranged in a front and back mode, the screw tightening rod seat and the tight pressing rod seat are correspondingly arranged in the longitudinal direction, and the four chain rods enable the left-hand thread supporting seat, the right-hand thread supporting seat, the screw tightening rod seat and the tight pressing rod seat to be hinged. A half screw rod is arranged between the left-hand thread supporting seat and the right-hand thread supporting seat in a penetrating mode, a screw tightening screw rod is connected at the outer end of the screw tightening rod seat, a tight pressing rod is connected at the outer end of the tight pressing rod seat, and the screw tightening screw rod, the tight pressing rod and the horizontal center line of an octagonal hinge assembly formed by the left-hand thread supporting seat, the right-hand thread supporting seat, the screw tightening rod seat, the tight pressing rod seat and the chain rods are coaxial. The hoop component is arranged on the half screw rod between the right-hand thread supporting seat and the left-hand thread supporting seat, the tackle component is arranged on the bottom of the hoop component, and the hand wheel component is fixed at one stretch-out end of the half screw rod. The adjustable tight pressing device for the forming mill is smooth in operation, reasonable in structure and capable of effectively improving the working efficiency of the forming mill.

Description

technical field [0001] The invention relates to auxiliary production equipment of a push-pull cold bending machine for large-diameter thick-walled pipes, in particular to an adjustable jacking device for a cold bending machine. Background technique [0002] In the current bending pipe tightening mechanism, one end of the tightening rod is fixed on the slider seat of the pipe bender, and the other end is set together with one end of the tightening screw, and the tightening screw is driven by external force to move the tightening rod and the slider seat. To the required position, so that the slider seat will not move when the force is applied. When the distance required to be adjusted is large, it is necessary to replace a longer or shorter jacking rod, and when replacing the jacking rod, it is necessary to disassemble the top plate arranged on the slider seat, which is labor-intensive, time-consuming and labor-intensive. Contents of the invention [0003] The object of the...
