Metal plate bending equipment

Abstract

The invention discloses metal plate bending equipment. A rack, a lower die, an upper die, a straightening rod, a detection device and a conveying device are specifically included. The output end of ahydraulic cylinder is connected with a rod sleeve in an inserted manner. Limiting rods are arranged on the left side and the right side of the bottom of the lower die. Limiting barrels are arranged atthe top ends of the limiting rods. The straightening rod is horizontally arranged between the upper die and the lower die. The conveying device is arranged on one sides of the upper die and the lowerdie. According to the metal plate bending equipment, a clamp is used for clamping a panel, then, a telescopic clamping rod is used for pushing the panel to the position between the upper die and thelower die, the panel is straightened under pushing of the straightening rod, the hydraulic cylinder is used for making the push rod drive the upper die to downwards conduct punching, and the effect ofbending is achieved; the clamp is used for clamping the panel, the telescopic clamping rod is used for pushing the panel into a detection barrel, and the panel is right placed in the detection barrel; and through stretching and contracting of a second telescopic rod, an inductor on the inner wall of the detection barrel makes contact with the panel, and whether the situations of cracking and damage exist in the panel or not is detected.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a metal plate bending equipment. Background technique [0002] Metal plate bending is under the pressure of the upper die or the lower die, first undergoes elastic deformation, and then enters plastic deformation. In the initial stage of plastic bending, the sheet is free to bend. Pressure is applied, and the sheet material and the inner surface of the V-shaped groove of the lower die are gradually closed, and the radius of curvature and the bending arm are also gradually reduced. Continue to pressurize until the stroke ends, so that the upper and lower dies are in full contact with the sheet at three points, so as to achieve bend. [0003] With the existing bending equipment, the plate cannot be aligned between the upper film and the lower film during bending, which makes it easy to be skewed when stamping the plate, thus affecting the normal processing of the pla...

Problems solved by technology

[0003] With the existing bending equipment, the plate cannot be aligned between the upper film and the lower film during bending, which makes it easy to be skewed when stamping the plate, thus affecting the normal processing of the plate. Considering the The needs of bending, for this reason, we propose a metal plate bending equipment
