Description

A mechanical bending machine

Technical Field

The utility model belongs to the field of mechanical processing, and specifically relates to a mechanical processing bending machine.

Background Art

In the existing mechanical processing, metal plates or other plate parts need to be bent, and bending operations require the use of bending machines. Bending machines are divided into manual bending machines, hydraulic bending machines and CNC bending machines. Hydraulic bending machines are based on the principle of hydraulic transmission, with single and stable tasks, less impact, vibration and noise. The hydraulically driven pressing head squeezes the fold line to achieve bending.

The Chinese patent application number CN214639304U discloses a utility model. The utility model discloses an adjustable bending device for mechanical processing, including a chassis, a top plate connected to the top of the chassis by a supporting column, a pressing mechanism is provided on the side of the top plate close to the chassis, and a hydraulic driving part for driving the pressing mechanism is provided on the top plate. A first placing plate for placing a metal plate is provided on the side of the chassis close to the top plate, and the second placing plate is connected to the side where the two groups of first placing plates are close to each other. A sliding groove for sliding the second placing plate is provided in the first placing plate, and the side of the second placing plate away from the first placing plate is connected to a fixed seat, and a protective mechanism for protecting the metal plate during the bending operation is provided on the fixed seat. The utility model is designed according to existing needs. The distance between the two groups of fixed seats can be adjusted by pushing the assembly, thereby facilitating the adjustment of the bending angle of the metal plate and facilitating the use of the device. The pressing head in the pressing mechanism is easy to replace, so that the bending operation can be performed using pressing heads with different curvatures.

However, when processing the workpiece, this comparative document can adjust the distance between the placement plates to facilitate the adjustment of the bending angle of the metal plate. However, once the angle is adjusted, the external pressing head needs to be replaced back and forth, which is troublesome and affects production efficiency.

In view of this, the present utility model is proposed.
