A swing arm sliding rail type vertical roll changing manipulator

Abstract

The invention discloses a roller exchanging mechanical arm for a swing arm slide rail type vertical roller. The roller exchanging mechanical arm for the swing arm slide rail type vertical roller comprises a swing arm pedestal, a roller exchanging hydraulic cylinder, a side seat is arranged at one side of the swing arm pedestal, the side seat is connected with a left swing arm and a right swing arm through a swing arm rotary shaft; the left swing arm and the right swing arm can rotate corresponding to the side seat; the structure of the right swing arm and the structure of the left swing arm are symmetrical; the left swing arm is provided with a swing arm slide rail; the swing arm pedestal is provided with a lift limit support block and a right limit support block, the outer sides of the lift limit support block and the right limit support block are respectively connected with the open groove pressing plate through the locking bolts; a jack-up small air cylinder is arranged on the swing arm pedestal; the roller exchanging hydraulic cylinder is arranged behind the side seat; the piston rod of the roller exchanging hydraulic cylinder is connected with the pull rod of the vertical roller box at front side of the side seat. The roller exchanging mechanical arm for the swing arm slide rail type vertical roller is simple, convenient and fast in operation, simple in structure, safe and reliable in use, the roller exchanging efficiency is raised, the continuous rolling production can be effectively guaranteed, the client cost of investment is reduced and the market competitiveness is raised.

Description

technical field [0001] The invention relates to the field of vertical roll changing equipment, in particular to a swing arm slide rail type vertical roll changing manipulator. Background technique [0002] Such as figure 1 As shown, the vertical roll box of the high-rigidity short-stress universal rolling mill is a built-in type. The existing vertical roll change manipulator mainly consists of a half frame 51, a vertical roll box 52, a lateral movement and turning mechanism 53, and a roll change hydraulic cylinder 54. , traversing hydraulic cylinder 55, turning hydraulic cylinder 56, inserting plate 57, clamping plate and tie rod 59, vertical roll box 510, etc., the roll changing operation process is as follows: 1. First, lift the half frame 51 with the horizontal roll removed Enter the frame seat of the vertical roll changing manipulator half-frame, and fix it with bolt locking; 2, then move the hydraulic cylinder 55 to move horizontally, so that the horizontal shift turni...

AI Technical Summary

Problems solved by technology

[0003] According to the above roll change process, it can be seen that the operation process of the existing vertical roll change manipulator is quite complicated, and during the operation process, the roll change hydraulic cylinder and the lateral movement hydraulic cylinder have a sequence of actions. According to the feedback from the site, it is easy Misoperations lead to equipment failure, which directly affects the efficiency of roll changing; the hydraulic cylinder has many actions, and the on-site roll changing process requires close operation between the worker and the equipment, too many actions, and the lower the safety; and the equipment contains many sub- Structure, complex structure, high processing requirements, high investment costs, insufficient competitiveness in the current environment of overcapacity steel rolling and micro-profit
