Flat steel straightening machine used for maintenance of civil defense door

Abstract

The invention discloses a flat steel straightening machine used for maintenance of a civil defense door. The flat steel straightening machine used for maintenance of the civil defense door comprises abase plate, supporting legs, a fixing frame, a guide plate, top rollers, a longitudinal push-rod motor, a fixed plate, a horizontal push-rod motor, a driving motor, a threaded rod, a movable plate, an adjustment motor, a rotary plate, a control panel, and a sliding block. The supporting legs are fixed to the four corners of the bottom of the base plate. The fixing frame and a mounting frame are mounted at the top of the base plate. The fixed plate is fixed to one end of the mounting frame. The driving motor is mounted in the fixed plate. The bottom rollers are mounted at the bottom of the mounting frame at equal intervals. According to the flat steel straightening machine used for maintenance of the civil defense door, the horizontal push-rod motor, the longitudinal push-rod motor, the movable plate and an adjustment plate are arranged to adjust the distance between the top rollers and the bottom rollers and to limit the flat steel machining width of the top rollers and the bottom rollers so that flat steel with different sizes can be better adjusted, the time for replacing the straightening machine is saved for people, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a straightening machine, in particular to a flat steel straightening machine used for overhauling civil air defense doors, and belongs to the technical field of overhauling and repairing civil air defense doors. Background technique [0002] Straightening machine, also called straightening machine, straightening and cutting machine, straightening and cutting machine. Straightening and breaking machine is a kind of straightening equipment. Straightening machine is one of the steel bar processing machines. It is used to straighten and cut steel bars with a diameter of less than 14mm. The cutting length can be customized according to customer requirements. It can straighten and cut stainless steel wires, aluminum wires, cold drawn wires, plastic-coated steel wires, etc., with neat cuts, small errors, and good performance. Some straightening machines are more difficult to straighten some larger flat steel. [0003] Existing pate...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of adjusting the movement of the flat steel when the straightening machine is working and the straightening machine cannot straighten flat steels of different sizes. By rotating the rotating plate, the rotating plate drives the threaded rod to rotate. The threaded rod is meshed with the internal thread provided in the side wall of the fixed frame, and the threaded rod is rotatably connected with the guide plate, so that the guide plate moves away from the rotating plate, the width of the flat steel is limited, and the moving plate is pushed by the horizontal push rod motor Move towards the direction away from the fixed plate, change the processing width between the movable plate and the end of the fixed frame away from the fixed plate, so that the width of the flat steel is better, and the longitudinal push rod motor pushes the two adjustment plates to move downward, so that the adjustment plate The height between the bottom plate and the bottom plate is changed, and at the same time, it drives the top roller to move downward, so that the distance between the top roller and the bottom roller is equal to the height of the flat steel
