Description
Technical field
The present invention relates to workpiece machining equipment fields, more particularly to a kind of safe and reliable bending machine.
Background technique
Bending machine is a kind of machine that bending can be carried out to thin plate, and structure mainly includes bracket, workbench and clamping
Plate, workbench are placed on bracket, and workbench is made of pedestal and pressing plate, and pedestal is connected by hinge with clamping plate, and pedestal is by seat
Shell, coil and cover board composition, coil are placed in the recess of seat shell, and recessed top is covered with cover board.Coil is led to by conducting wire when use
Electricity generates gravitation to pressing plate after energization, to realize the clamping to thin plate between pressing plate and pedestal.It is pressed from both sides due to using electromagnetic force
It holds, so that pressing plate can be made various workpieces requirement, and the workpiece for having side wall can be processed, it is also very simple in operation
Just.
During carrying out bending to thin slice, generally requires staff and thin slice is helped manually, and right
When one end of thin slice carries out bending, in order to cooperate its bending to work, the other end of thin slice then needs to approach at body, at this time
The staff helped thin slice will appear the case where touching with the body that is working, caused by security risk, meanwhile,
Bending Processing is carried out since thin slice is simply helped merely by staff, thin slice biggish for area is carrying out
When bending works, it is easy to it is unstable to thin slice displacement occur there is a phenomenon where helping, the essence of thin slice processing will be destroyed at this time
Accuracy reduces the qualification rate of work pieces process.
Summary of the invention
