A multi-roller CNC plate rolling machine and its control circuit

Abstract

The invention belongs to the technical field of curved plate production, and particularly relates to a multi-roller numerical control plate bending machine and a controlling circuit thereof. The machine comprises a base, two secondary rotary rollers and a driving roller; two vertically upwards hydraulic rods are fixed to both ends of the upper surface of the base respectively; the upper ends of the hydraulic rods are fixedly connected with shock absorbing devices; the two secondary rotary rollers are horizontally and parallely arranged; the two ends of the two secondary rotary rollers are rotatably connected with the upper ends of the corresponding shock-absorbing devices through rotary shafts; vertically arranged supporting plates are connected with the parts, located in the middles of the two hydraulic rods, of the two ends of the base respectively; the driving roller is arranged in the middle of the upper ends of the two secondary rotary rollers; the two ends of the driving roller are rotatably connected with the corresponding supporting plates respectively; a motor is fixedly connected with the face, away from the driving roller, of the left side supporting plate; a rotary shaft of the motor penetrates through the supporting plate to be fixedly connected with the driving roller; an electric control box is fixedly connected with the face, away from the driving roller, of theright side supporting plate.

Description

technical field [0001] The invention belongs to the technical field of coiling production, in particular to a multi-roller numerically controlled coiling machine and a control circuit thereof. Background technique [0002] The plate rolling machine is a shaping machine tool for continuous point bending of the plate. It has the function of rolling plates of different shapes such as O-shape, U-shape, and multi-section R. Three-roller plate rolling machine has mechanical type and hydraulic type: Mechanical three-roller plate rolling machine is divided into symmetrical and asymmetrical. The sheet metal can be rolled into circular, curved and conical workpieces within a certain range. [0003] There are also some technical solutions for plate rolling machines in the prior art, such as a Chinese patent with application number 2017202813176, a multi-roll plate rolling machine, including a plate rolling machine, a front baffle, a rear baffle, and a first hydraulic pusher , a secon...

AI Technical Summary

Problems solved by technology

[0004] This technical solution uses copper rollers to shape the plate, which can dissipate heat well, but the cost of copper products is too high to be suitable for mass production, and only cooling by air cannot reduce the temperature well, and it is still very difficult for the staff to collect materials. Trouble, air cooling has seasonal restrictions, for example, the high air temperature in summer cannot cool down the roller
