[0002] Shearing machine is a machine that shears plates by reciprocating linear motion of one blade relative to another blade. It applies shearing force to metal plates of various thicknesses by using a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap, so that the plates are broken and separated according to the required size. Shearing machine is a kind of forging machine, and its main function is metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electricity, electrical appliances, decoration and other industries to provide the required special machinery and complete equipment. The existing shearing machine is a bevel blade shearing machine. Due to the shearing angle, the sheared part of the plate has bending stress, which will cause the sheared plate to bend and distort. The narrower the width of the material, the greater the degree of distortion.

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

An upper blade 4 is arranged above the shearing machine workbench 2, and support frames 5 are movably arranged inside the plurality of fixing seats 3, and anti-skid pads 6 are fixed on the top surfaces of the plurality of support frames 5, and two adjusting studs 7 are respectively arranged inside the plurality of support frames 5, and the two adjusting studs 7 respectively penetrate the interior of the support frames 5, and the outer walls of the two adjusting studs 7 are respectively surrounded by a plurality of compression springs 8, and the top ends of the two compression springs 8 at the uppermost ends are respectively fixedly connected to the bottom surfaces of the support frames 5, and the threaded ends of the two adjusting studs 7 are respectively threadedly connected to two nuts 9, and the two adjusting studs 7 are respectively fixed to the support frames 5 by the two nuts 9.

[0022] During use, the upper plane of the support frame 5 is flush with the upper plane of the lower blade 1. During shearing, the support frame 5 moves downward synchronously with the upper knife frame under the action of the upper blade 4. The upper blade 4 and the support frame 5 clamp the plate on the upper and lower surfaces of the sheared plate at the same time. The clamping force is generated by the compression spring 8. The anti-slip pad 6 can increase the anti-slip property, thereby improving the stability. By rotating the nut 9 to compress the compression spring 8 sleeved on the adjusting stud 7, the support frame 5 generates an upward supporting force when it contacts the plate. The size of the clamping force can be changed by adjusting the compression amount of the compression spring 8. The clamping force balances the twisting force of the sheared plate so that the sheared plate does not produce twisting and deformation. The fixed seat 3 bears lateral force and bending force. It is suitable for shearing narrow strips of long plates (shearing length 6-12 meters) with a full-length straightness of 2mm.

[0023] The clamping force can be changed by adjusting the compression amount of the compression spring 8 so that the sheared sheet material will not be twisted or deformed. The overall structure of the device is simple, easy to use, low in manufacturing cost, and high in reliability, thereby reducing equipment cost and maintenance cost.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, guide sleeves 10 are respectively provided between the plurality of fixing seats 3 and the plurality of supporting frames 5 .

[0025] During use, the fixing seat 3 secures the support frame 5 on the side wall of the shearing machine workbench 2 through the guide sleeve 10, reducing shaking, effectively enhancing the stability of the entire device, and improving work efficiency and shearing accuracy.

[0026] like Figure 1-Figure 3 As shown, the outer walls of the two adjusting studs 7 are respectively provided with a plurality of stabilizing sleeves 11, and the plurality of stabilizing sleeves 11 are respectively arranged between a plurality of compression springs 8 at intervals. A fixed bottom plate 12 is fixed to the bottom end of the adjusting stud 7, and the top surface of the fixed bottom plate 12 is fixedly connected to the bottom ends of the two compression springs 8 at the bottom.

[0027] In use, the stabilizing sleeve 11 is used to support the compression spring 8, and the stability of the compression spring 8 is maintained during the shearing process, ensuring the balance and durability of the clamping force. The fixing base plate 12 is used to provide support for the adjustment stud 7, increasing the contact area with the foundation, thereby enhancing the stability of the entire device and improving the safety and efficiency of the shearing operation.

[0028] like Figure 1-Figure 4 As shown, the internal threads of the fixed base plate 12 are connected with bolts 13, and the fixed base plate 12 is fixed to the foundation by the bolts 13, and the upper plane of the support frame 5 is an inclined plane.

[0029] During use, the bolts 13 are used to fix the fixed base plate 12 on the foundation, thereby improving the stability of the fixed base plate 12 and thus improving the stability of the device.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
