Description

Technical Field

[0001] The utility model relates to the technical field of blanking, in particular to a swing blanking structure of a numerically controlled plate shearing machine. Background Art

[0002] A shearing machine is a device used for cutting and trimming metal sheets. It is usually composed of a cutting head, a workbench and a control system. After cutting, the material is usually unloaded manually. For example, the fixed plate CNC shearing machine described in publication number CN220259668U includes a box, a cutter, a mounting block, a limit block and a mounting frame. The upper end of the box is provided with a mounting frame, the lower end of the mounting frame is provided with a cutter, a limit block is provided on one side of the cutter, and a limit rod is provided on one side of the limit block;

[0003] The above-mentioned device achieves a stable positioning effect of the plate before and after cutting by using a limit block and a stretchable telescopic rod, thereby ensuring the stability of cutting. It solves the problem that the existing plate shearing machine lacks the function of stably fixing the plate, which makes the plate easily deviate from the original track under rapid cutting and high-frequency vibration. However, manual unloading is required after cutting is completed, which increases the burden on the staff. Utility Model Content

[0004] The utility model aims to provide a swing blanking structure for a numerically controlled plate shearing machine to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The swing blanking structure of the CNC shearing machine includes a mounting frame installed on the front surface of the CNC shearing machine body, the side surface of the mounting frame is rotatably connected with a rotating shaft, the outer surface of the rotating shaft is fixedly connected with a worm gear, the outer surface of the mounting frame is fixedly connected with a stepping motor, the output end of the stepping motor is fixedly connected with a worm, both ends of the rotating shaft are fixedly connected with a limiting frame, the upper surface of one of the limiting frames is embedded with an insertion rod movably connected, one end of the insertion rod is rotatably connected with a negative pressure box, the upper surface of the CNC shearing machine body is threadedly connected with a sleeve, the inside of the sleeve is movably connected with a piston rod, the upper surface of the CNC shearing machine body is fixedly connected with a hydraulic rod, and the output end of the hydraulic rod is fixedly connected with a cutter.

[0007] Furthermore, the worm and the worm wheel are meshingly connected, and the lower end of the piston rod is fixedly connected to the upper surface of the cutter.

[0008] Furthermore, the other end of the rotating shaft is fixedly connected to an electric push rod, the output end of the electric push rod is fixedly connected to a fixing frame, the upper surface of the fixing frame is embedded with an insertion tube, the insertion tube is inserted into the interior of the limiting frame, and the insertion tube and the limiting frame are slidably connected.

[0009] Furthermore, a tracheal rotary joint is embedded and rotatably connected to the other side surface of the negative pressure box, and the insertion tube and the tracheal rotary joint are connected and conducted.

[0010] Furthermore, a metal hose is fixedly connected to the upper end of the sleeve, the other end of the metal hose is fixedly connected to the trachea rotary joint, the outer surfaces of the CNC shearing machine body and the limit frame are fixedly connected to limit rings, and the metal hose passes through the limit rings.

[0011] Furthermore, a suction cup is embedded and fixedly connected to the lower surface of the negative pressure box.

[0012] Furthermore, the upper end of the piston rod is fixedly connected with a piston head, and the piston head is slidably connected to the inner wall of the sleeve.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Through the set sleeve, when the hydraulic rod drives the cutter to move downward, the cutter drives the piston rod to move downward. At this time, the piston head moves downward, so that the sleeve cooperates with the metal hose to perform air extraction operation. The metal hose and the negative pressure box are connected. Therefore, when the cutter moves downward, the sleeve cooperates with the metal hose to evacuate the negative pressure box, so that the negative pressure box cooperates with the suction cup to suck the plate. The negative pressure box limits the plate on the main body of the CNC shearing machine to avoid the plate from shifting when the cutter is cutting.

[0015] 2. The negative pressure box is set up and can rotate freely. When the negative pressure box sucks the plate and the electric push rod drives the plate to rise, the plate is close to the main body of the CNC shearing machine under the action of gravity. When the rotating shaft drives the limit frame to swing, the plate is close to the ground. At this time, the hydraulic rod drives the cutter to rise, and the inside of the negative pressure box is in a normal pressure state, so that the suction cup can release the plate, which is convenient for unloading the plate on the main body of the CNC shearing machine.
