The loading and unloading assembly further comprises a first sliding column 320 and a second sliding column 330, wherein the first sliding column 320 and the second sliding column 330 are vertically and fixedly connected to the inner wall of the bottom plate 120; the first sliding column 320 and the second sliding column 330 are respectively located at two sides of the second hydraulic cylinder 170, a first sliding hole (not shown) is vertically formed at a position of the second plate 380 close to the first plate 370, a second sliding hole (not shown) is vertically formed at a position of the second plate 380 close to the third plate 390, the first sliding column 320 is slidably arranged through the first sliding hole, and the second sliding column 330 is slidably arranged through the second sliding hole, so that the lifting frame 180 can only vertically move.

Through the technical scheme, automatic feeding and discharging of the H-shaped steel can be realized, when feeding is needed, a web plate of the H-shaped steel is placed on the upper surface of the main bearing plate 190, then the second hydraulic cylinder 170 is started, the lifting frame 180 is lifted, so that the first roller 480 is lifted and extends out of the first groove 510, the second roller 350 is lifted and extends out of the second groove 520, so that the first roller 480 and the second roller 350 are both contacted with the lower surface of the web plate of the H-shaped steel, the motor 420 is started to drive the third grooved wheel 450 to rotate, so that the first grooved wheel 340 and the second grooved wheel 360 are driven to rotate, so that the first roller 480 and the second roller 350 are driven to rotate (the fourth grooved wheel 470 and the idler wheel) so as to drive the H-shaped steel to move on the main bearing plate 190, so that feeding is realized, after the feeding is finished, the motor 420 is stopped, the second hydraulic cylinder 170 is restarted, so that the lifting frame 180 is lowered, thereby lowering the first roller 480 into the first groove 510 and lowering the second roller 350 into the second groove 520 to avoid interfering with the securing of the platen 220.

When blanking is needed, the pressing plate 220 is lifted by the first hydraulic cylinder 210, then the second hydraulic cylinder 170 is started, the lifting frame 180 is lifted again, so that the first roller 480 is lifted and extends out of the first groove 510, the second roller 350 is lifted and extends out of the second groove 520, the first roller 480 and the second roller 350 are both in contact with the lower surface of the web of the H-shaped steel, the motor 420 is started again, the third sheave 450 is driven to rotate, the first sheave 340 and the second sheave 360 are driven to rotate, the first roller 480 and the second roller 350 are driven to rotate, the H-shaped steel is driven to move on the main bearing plate 190, and blanking is achieved; and manual feeding and discharging are not needed, so that the device is more convenient and labor-saving.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
