Description

Technical Field

[0001] The invention relates to the technical field of shearing machines, in particular to a shearing mechanism of a shearing machine. Background Art

[0002] A shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear a plate. It uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shearing force to metal plates of various thicknesses, so that the plates can be broken and separated according to the required size. The working principle of the shearing machine is based on the reasonable gap and shearing force between the blades to ensure that the plates can be broken and separated according to the predetermined size. For example, the Chinese invention application with publication number CN107186262A discloses a shearing machine, which includes a support seat, a support plate, a support frame and a cutting plate; the support frame is fixed to the support seat; the two ends of the cutting plate are slidably connected to the support frame, and the telescopic rod of the cylinder passes through the support frame and is connected to the cutting plate. The telescopic rod of the cylinder is telescopic in the vertical direction so that the cutting plate can move in the vertical direction; the support plate is fixed to the support seat; but the shearing mechanism of the current shearing machine has the following defects:

[0003] The shearing mechanism of the current shearing machine will press down the surface of the plate through the pressing mechanism when shearing, so as to prevent the plate from moving during shearing. However, in order to ensure that the bottom surface of the plate will not be scratched when passing through, the shearing machine will use a smooth material, or directly support the plate through ball bearings. In this way, it is very unreliable to fix the plate only by applying pressure from above. The pressure generated when the upper blade presses down can easily cause the bottom of the plate to slide, resulting in damage to the cut surface, affecting the shearing effect. In order to prevent the lower blade from scratching the plate, there will be a distance of several millimeters between the lower blade and the plate. Therefore, the cut surface after shearing will generally have a certain inclination and poor cut surface quality.

[0004] For this reason, we propose a shearing mechanism of a shearing machine to solve the above problems. Summary of the invention

[0047] See also Figure 1-10, which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. When the present invention is used, the lifting equipment lifts the plate onto the feeding table 21, and the second cylinders 28 on both sides drive the second push plates 29 to apply force on both sides of the plate to calibrate the position. Then the first push plate 26 pushes the plate into the shearing component 1 position, and stops after reaching the shearing position. The driving component 3 drives the pressure column 18 to press down, and at the same time drives the support column 112 to move up to fix the plate. At the same time, the knife seat 116 is driven to move by the small cylinder 137. After the lower knife 117 contacts the plate, the micro cylinder 147 drives the positioning block 148 to insert into the positioning port 149 to lock the position of the knife seat 116. Then the hydraulic cylinder 12 9 drives the upper knife 115 to press down to complete the shearing work; when the present invention is shearing, the pressure column 18 is used to press the surface of the plate, and the support column 112 at the bottom moves up, so that the support column 112 and the pressure column 18 clamp the top and bottom surfaces of the plate, so that the bottom of the plate can also form a good fixing effect, which is more reliable when shearing, and the plate will not move, thereby ensuring the shearing effect; the knife seat 116 is set in a vertical sliding manner, so that the lower knife 117 can move, and when the plate enters, the lower knife 117 moves down to avoid scratching the plate. After the plate is fixed, the lower knife 117 moves up to contact the plate at the same time, so that the lower knife 117 directly presses against the plate during shearing, and the cutting effect is better.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
