Abstract

The invention relates to a tension control device and belongs to the technical field of mechanical control devices. The tension control device comprises a servo motor, a PLC, a linear module composed of a linear module support, a ball lead screw and a module sliding block, a sensor and a clamping mechanism composed of a movable plate support, a four-rod mechanism fixed support, a first rod, a first screw bolt, a second rod, a movable plate, a third rod, a screw, a second screw bolt, a fourth rod, a four-rod mechanism movable support, a left clamping block and a right clamping block. The motor, the sensor and the PLC are connected. The PLC controls the servo motor to rotate. The motor drives the ball lead screw to rotate so as to drive the module sliding block to conduct linear movement so that the clamping mechanism can conduct linear movement. The tension control device aims at solving the problem that the forming accuracy of a bent part is low due to the fact that tension on a bender, a stretch bender and other bending equipment cannot be controlled precisely.

Description

technical field [0001] The invention relates to a device for controlling tension, which belongs to the technical field of mechanical control devices. Background technique [0002] Bending is one of the more complicated processes in the forming process, which is often affected by factors such as material properties, mold shape, and loading path. In particular, profiles with complex cross-sections are often in a very complex stress state during bending. The inward movement of the stress neutral layer, the outer rupture, the inner wrinkling, residual stress and springback are all reasons that affect the performance and accuracy of the formed part. The pre-tensioning and control of tension can effectively restrict the influence of the above factors on the forming accuracy of bending parts. [0003] At present, there is no device for controlling tension in the existing pipe bending machines, including stretch bending machines and other equipment for processing bending parts, or...
