[0002] Shears are a type of mechanical equipment used to cut sheet metal and are widely used in industries such as metal processing, manufacturing, and construction. They can efficiently and accurately shear sheet metal into the desired size and shape.

[0003] Traditional shearing machines mostly rely on manual clamps or workers pushing the plates to cut the plates. This method not only makes it difficult to ensure cutting accuracy, but also greatly reduces cutting efficiency and poses certain safety hazards. Utility Model Content

[0004] In view of this, the utility model provides a limiting device that is convenient for fixing the plate. The plate can be firmly and stably clamped and fixed through the limiting mechanism, and the plate can be stably pushed forward through the pushing mechanism. In conjunction with the shearing machine, the plate can be cut quickly, efficiently and accurately, making the operation safer and more convenient.

[0006] The pushing mechanism includes a pair of fixed seats arranged on the outside of the workbench, each fixed seat is provided with a linear slide, and a connecting plate is provided between the sliders of the two linear slides. The linear slide is a linear slide in the prior art in which a motor drives a lead screw to rotate. The two linear slides move synchronously. The utility model can rotate the screw together with the rotation of the output shaft of the motor. Due to the guiding and limiting effect of the slide rail of the linear slide on the linear slide, and the threaded connection between the screw and the slider of the linear slide, the rotating screw can drive the slider of the linear slide to move along the slide rail of the linear slide with the connecting plate thereon.

[0007] The connecting plate is U-shaped, and the lower part of the connecting plate is fixedly arranged with the upper parts of the sliders of the two linear slides.

The limiting mechanism 400 includes a pair of clamping plates 401 arranged between the connecting plates 300, and a telescopic push rod 402 is provided on the outside of each clamping plate 401. The telescopic push rod 402 is an electric push rod or a hydraulic push rod. The utility model can realize the firm and stable clamping and fixing operation of the plate between the two clamping plates 401 by the extension of the output rod of the telescopic push rod 402, and can push the limiting mechanism 400 and the clamped and fixed plate on its upper part forward by the pushing mechanism 200, and cooperate with the shearing machine to realize the shearing operation of the packaging material, which is more convenient, stable, labor-saving, efficient and safe to operate.

[0023] According to one embodiment of the present invention, Figure 1-4 As shown, the pushing mechanism 200 includes a pair of fixed seats 201 arranged on the outside of the workbench 100, and each fixed seat 201 is provided with a linear slide 202, and the connecting plate 300 is arranged between the sliders of the two linear slides 202. The linear slide 202 is a linear slide 202 driven by a motor to rotate the lead screw in the prior art. The two linear slides 202 move synchronously. The utility model can rotate the screw together with the rotation of the output shaft of the motor. Due to the guiding and limiting effect of the slide rail of the linear slide 202 on the linear slide 202, and the threaded connection between the screw and the slider of the linear slide 202, the rotating screw can drive the slider of the linear slide 202 to move along the slide rail of the linear slide 202 with the connecting plate 300 thereon.

[0024] According to another embodiment of the present invention, Figure 1 and Figure 2 As shown, the connecting plate 300 is U-shaped, and the lower portion of the connecting plate 300 is fixed together with the upper portions of the sliders of the two linear slides 202 .

[0025] The clamping plate 401 is L-shaped, so as to facilitate the clamping and fixing of the side wall of the plate, thereby achieving a firm and stable clamping operation of the plate.

[0026] According to another embodiment of the present invention, Figure 1 and Figure 3 As shown, through holes are respectively provided on the side walls of the two vertical parts of the connecting plate 300, and the output rod of the telescopic push rod 402 passes through the through holes on the same side as the connecting plate 300, and mounting plates 403 are respectively provided on the outer side walls of the two vertical parts of the connecting plate 300, and the fixed end of the telescopic push rod 402 is provided on the mounting plate 403 on the same side as the connecting plate. The utility model can push the clamping plates 401 at the ends of the telescopic push rod 402 closer to and away from each other by extending and retracting the output rod of the telescopic push rod 402, thereby achieving a firm and stable clamping and fixing operation of the plate and can also be adapted to the clamping and fixing operation of plates of different width specifications, making the operation more convenient and efficient.

[0027] According to another embodiment of the present invention, Figure 1 and Figure 4 As shown, a protective pad 404 is provided on the inner wall of the clamping plate 401. The protective pad 404 should be made of a non-slip, wear-resistant and shock-resistant material. The purpose of this is to avoid pinching the plate on the one hand, and on the other hand, it has better protection and anti-slip effects, making operation more convenient.

[0028] The use method of this utility model:

[0029] First of all, it should be made clear that the limiting device involved in the present invention is mainly used for firmly and stably clamping and fixing the plate and pushing the cutting operation when the plate is sheared. The present invention takes the clamping and fixing of the plate in the cutting process as an example to explain its method of use in detail. When the plate needs to be cut, the output rod of the telescopic push rod 402 is first started to retract until the distance between the two clamping plates 401 is greater than the width of the plate to be cut. Then the operator places the plate to be cut on the pad between the two clamping plates 401. Then the operator starts the output rod of the telescopic push rod 402 to extend until the plate between the two clamping plates 401 is clamped and fixed. Then the operator starts the motor of the linear slide 202 to rotate. By the action of the linear slide 202, the connecting plate 300 and the plate that has completed the fixed clamping operation on the clamping mechanism on its upper part are pushed to move along the slide rail of the linear slide 202, and then the shearing machine is started to work, so that the plate clamped by the clamping plate 401 transmitted through the linear slide 202 can be efficiently, quickly and stably cut. The utility model can realize the firm and stable clamping and fixing operation of the plate between the two clamping plates 401 by the extension of the output rod of the telescopic push rod 402, and can push the limiting mechanism 400 and the clamped and fixed plate on its upper part forward through the pushing mechanism 200, and cooperate with the shearing machine to realize the shearing operation of the packaging material, which is more convenient, stable, labor-saving, efficient and safe to operate.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
