Angle shearing machine capable of automatically adjusting blade gap

Abstract

The invention provides an angle shearing machine capable of automatically adjusting a blade gap according to conditions of sheet metal. The angle shearing machine comprises an upper blade, a lower blade, an upper shearing seat, a lower shearing seat, a guide pillar, a fixed gap adjusting device and a power device; the guide pillar is arranged on the lower shearing seat; the upper shearing seat can do up-down reciprocating motion relative to the lower shearing seat under the driving of the power device; especially, a slider and chute pair which can do linear motion on the horizontal direction is formed between the lower part of the guide pillar and the lower shearing seat, and the motion path of the slider and chute pair is coplanar with a symmetric line of the lower blade; and an automatic gap adjusting device which can press or draw the guide pillar to be close to the lower blade is formed between the lower part of the guide pillar and the lower shearing seat. The angle shearing machine has the advantages: (1) the step of manually moving a test panel is avoided under the condition that the panel thickness is changed little, materials are saved, and the cost is reduced; and (2) the gap amount between the upper blade and the lower blade can be automatically adjusted according to the conditions of sheet metal, and the service life of the blades are prolonged.

Description

technical field [0001] The invention relates to an angle shearing machine for punching out missing corners on a plate, in particular to an angle shearing machine with the function of automatic adjustment of blade gaps. Background technique [0002] The corner shearing machine is a machine that punches out corners on the edge of the sheet, which can be used in the production process of the air duct, so that the end of the sheet that has been punched out of the corner can be made into an air duct after being folded. flange department. [0003] The working principle of the angle shearing machine is similar to that of the punching machine. It includes a set of upper blades that can move up and down and a set of fixed lower blades. When the upper blade moves down and cooperates with the lower blade, it can A notch is punched on the edge of the sheet between the blade and the lower blade. And according to the difference of sheet material thickness, skilled worker needs to adjust...

Problems solved by technology

[0005] However, although the fixed gap adjusting device can adjust the gap value between the upper blade and the lower blade, the gap value remains unchanged during the production process

In the event of uneven thickness of the sheet or wrinkling of the edge of the sheet, the gap value between the upper blade and the lower blade will not change accordingly, which will affect the life of the upper blade and the lower blade, thereby affecting the processing quality and production efficiency

Moreover, in the existing angle shearing machines, technical workers need to adjust the shear gap value once for sheets of different thicknesses, which will take a long time for debugging and is not conducive to the guarantee of production efficiency.
