Compared with the prior art, the shearing mechanism is applied to shearing and processing of bar scrap 700, the shearing assembly is provided with the cutter withdrawing assembly, the shearing assembly drives the cutter 100 and the cutter withdrawing assembly to move downwards, after the bar is sheared, the cutter withdrawing assembly drives the cutter 100 to move along the horizontal direction to withdraw, a gap is formed between the cutter 100 and the bar, and then the shearing assembly drives the cutter in the cutter withdrawing state and the cutter withdrawing assembly to reset upwards. Therefore, the invention can completely avoid the cutter 100 dragging to the shearing surface of the bar and contacting with the shearing surface of the bar for the second time when resetting, thereby effectively improving the flatness of the shearing surface of the bar.
In one embodiment, the shear assembly comprises: a fixed frame 210; a cutting base 220 slidably connected to the fixing frame 210; the cutter 100 and the cutter withdrawing assembly are both arranged on the shearing seat 220; the shearing telescopic cylinder 230 is arranged on the fixed frame 210, a telescopic shaft of the shearing telescopic cylinder 230 is arranged along a vertical direction, and the shearing telescopic cylinder 230 is in driving connection with the shearing base 220, so that the shearing telescopic cylinder 230 drives the cutter 100 and the cutter withdrawing assembly on the shearing base 220 to reciprocate along the vertical direction.
Preferably, the shear cylinder 230 comprises a ram. Compared with the cylinder used as a driving source, the pressure provided by the oil cylinder is large enough, the operation is stable and quiet, the interference from the outside is small, and the cutting tool is more suitable for driving the cutter 100 to perform shearing work.
In one embodiment, the cutting block 220 is provided with a mounting cavity 221, and the tool retracting device comprises: a retracting telescopic cylinder 310 disposed on the mounting cavity 221; the telescopic shaft of the retracting telescopic cylinder 310 is arranged along the vertical direction; the connecting block 320 is in driving connection with the retracting telescopic cylinder 310; a cutter connecting base 330, which is connected with the connecting block 320 in a transverse sliding manner; the cutter connecting seat 330 is provided with an inclined guide rail 331; the inclined guide rail 331 is slidably connected with the shearing seat 220; the inclined guide rails 331 are arranged far away from the bar material in the top-down inclined direction; the cutter 100 is fixedly connected with the cutter connecting seat 330. In the invention, the telescopic shaft of the retracting telescopic cylinder 310 is arranged along the vertical direction, rather than transversely, so as to avoid that the retracting telescopic cylinder 310 is easily damaged when the transversely arranged telescopic shaft is subjected to the acting force in the vertical direction during shearing; after the telescopic shaft of the retracting telescopic cylinder 310 is arranged in the vertical direction, the direction of the shearing acting force is parallel to the direction of the telescopic shaft of the retracting telescopic cylinder 310, so that the service life of the retracting telescopic cylinder 310 is prolonged; because the telescopic shaft of the retracting telescopic cylinder 310 is vertically arranged, and the retracting telescopic cylinder 310 needs to drive the cutter 100 to transversely move, so that a transverse gap is formed between the cutter 100 and the shearing surface of the bar material, the cutter connecting seat 330 is transversely and slidably connected with the connecting block 320, and the inclined guide rail 331 is arranged on the cutter connecting seat 330, so that the cutter 100 can reciprocate along the inclined guide rail 331 under the driving of the retracting telescopic cylinder 310, and after the cutter 100 finishes shearing, the cutter 100 can perform an inclined transverse movement action, thereby avoiding secondary contact between the cutter 100 and the shearing surface of the bar material.
Preferably, the retracting telescopic cylinder 310 is connected with the connecting block 320 through an extension rod 340, and the extension rod 340 is arranged in the shearing seat 220 in a penetrating manner, so that the retracting assembly can drive the cutter 100 to move by using the retracting telescopic cylinder 310 with a short stroke, thereby reducing the manufacturing cost.
Preferably, the retracting and extending cylinder 310 comprises a pneumatic cylinder. The cylinder response speed is fast, saves the time that spare part removed to improve production efficiency.

After the cutter 100 shears the bar excess 700, a part of chips 800 are adhered to the back surface of the cutting edge of the cutter 100, and the chip removing telescopic cylinder 420 drives the material pushing rod 410 to move downwards to push out the chips 800 on the cutter 100, so that the effect of cutter shearing is prevented from being influenced by continuous accumulation of the chips 800.
Further, the middle parts of the cutter 100 and the cutter connecting seat 330 are provided with a clearance hole 500, the material pushing rod 410 is arranged in the clearance hole 500 in a penetrating manner, and a gap 600 is arranged between the clearance hole 500 and the material pushing rod 410, so that the material pushing rod 410 can smoothly perform reciprocating movement in the vertical direction.
Further, the value D of the gap 600 is larger than the traverse distance of the retracting blade. Thus, when the cutter 100 moves back for traversing, the clearance hole 500 does not contact with the material pushing rod 410, so that the movement of the cutter 100 is not affected when the material pushing rod 410 penetrates through the clearance hole 500.
The invention also provides extrusion processing equipment comprising the shearing mechanism.
As shown in fig. 5 to 10, the working principle of the shearing mechanism is as follows:
s1: the shearing telescopic cylinder 230, the retracting telescopic cylinder 310 and the scrap removing telescopic cylinder 420 are all in a contraction state;
s2: the shearing telescopic cylinder 230 drives the cutter withdrawing assembly and the cutter 100 to move downwards, so that the cutter 100 shears the bar discard 700;
s3: the scrap removal telescopic cylinder 420 drives the material pushing rod 410 to move downwards, and the scraps 800 on the cutter 100 are removed;
s4; the retracting telescopic cylinder 310 drives the cutter 100 to obliquely move away from the bar material, so that a transverse gap is formed between the cutter 100 and the shearing surface of the bar material;
s5: the shearing telescopic cylinder 230 is reset upwards;
s6: the scrap removing telescopic cylinder 420 is reset upwards, and the retracting telescopic cylinder 310 is reset upwards to complete one-time shearing work.
