Description

technical field [0001] The invention relates to a bending machine, in particular to a numerical control fully automatic electromagnetic bending machine. Background technique [0002] Traditional bending machines mainly use manual bending. The workpiece to be folded is placed between the platen and the platform. It is necessary to manually operate the rise and fall of the platen, and then manually lift and flip the baffle for bending. The operation of the traditional bending machine is time-consuming and laborious. The range of bending angles is small, the bending accuracy of products varies greatly, multiple bending processes of a single workpiece cannot be automated, the efficiency is low, and the function is single. [0003] Among the existing bending technologies, there are mainly manual bending, pneumatic bending and hydraulic bending. Manual bending is mainly formed by manual lifting or pressing down, pneumatic bending is mainly completed by high-pressure gas-driven cy...

AI Technical Summary

Problems solved by technology

[0006] 1. Manual bending requires manpower to operate the ascending and descending of the pressing plate and manually push the flip baffle to bend, which is time-consuming and labor-intensive, and the operation process must be in the state of operating the machine;

[0007] 2. The existing pneumatic bending machine cannot achieve bending in a large angle range of 0 to 165 degrees due to institutional limitations;

[0008] 3. Manual bending and pneumatic bending cannot do one-time precise forming, and the bending angle needs to be tested repeatedly. After adjustment is in place, different angles need to be re-tested, and the free control of the bending angle cannot be realized.

Hydraulic bending requires the use of forming dies, and is also limited by its own structure. It can only be adjusted within a few angle ranges, and it is difficult to achieve free control of the bending angle;

[0009] 4. Manual bending and pneumatic bending can only do fixed-angle bending of a single workpiece, and cannot realize fully automatic CNC bending of a single workpiece with continuous multiple bending angles by editing multi-segment bending programs

In this utility model, the automatic lifting function of the pressure plate 21 cannot be realized between the electromagnetic plate 31 and the pressure plate 21; there is no joint mechanism that can rotate 180 degrees, the bending ability is poor, and the bending range is generally 0 to 90 degrees; if there is no foot Stepping on the dual-position switch assembly requires manual operation, and it is impossible to use a single foot to control the foot-operated dual-position switch assembly to realize the single-foot control of the weak magnetic start, strong magnetic start and bending start of the electromagnetic controller during the bending process. The new type can not liberate both hands to operate, nor can it realize human-computer interaction, and can not achieve continuous bending of multiple bending angles for a single workpiece by editing multi-segment bending programs
