Bending machine used for bending plates

Abstract

The invention discloses a bending machine used for bending plates and belongs to the technical field of machining. The bending machine comprises a rack, an upper bending part, a lower bending part and a feeding mechanism. The lower bending part is fixedly arranged, and the upper bending part is arranged in a vertical sliding mode. A material pressing plate is correspondingly arranged above the lower bending part. The material pressing plate is arranged in a vertical sliding mode. The upper bending part comprises an ejecting block and a sliding pressing plate. The ejecting block is arranged in a vertical sliding mode. The sliding pressing plate is located on the lower surface of the ejecting block and is arranged in a reciprocating sliding mode in the feeding direction. The sliding pressing plate is provided with a sliding driving device in a matched mode. A round corner is arranged on the side, matched with the lower bending part, of the sliding pressing plate. A bending gap is reserved between the sliding pressing plate and the lower bending part. The feeding mechanism comprises driving rollers and driven rollers located above the driving rollers, and the driven rollers are connected with a lifting driving device. The bending machine ensures the bending precision and is capable of improving efficiency, simple, practical and obvious in effect.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a bending machine for bending plates. Background technique [0002] In machining, bending is an important process. During the use of the existing bending machine, after the steel plate is bent by the upper and lower dies of the bending machine, due to the certain elastic recovery of the steel plate itself, after bending at 90 degrees, it is often greater than 90 degrees, which is difficult Once the required angle is formed, it needs to be adjusted again, which reduces the accuracy and work efficiency. Contents of the invention [0003] The object of the present invention is to provide a bending machine for bending plates to solve the above problems. [0004] In order to achieve the purpose of the present invention, the technical solution adopted is: a bending machine for bending plates, including a frame, an upper bending part, a lower bending part and a feeding...
