AI Technical Summary
The existing shearing machines lack clamping mechanism between the push plate and the thin plate, which causes the thin plate to easily deviate during the push or shearing process, resulting in the deviation of the size of the sheared thin plate.
A clamping mechanism including a base plate, a slide block, a screw block, a clamping plate assembly and a cylinder is designed. The plywood assembly consists of a lower plywood and an upper plywood. The upper plywood is driven by a cylinder to press down and clamp the thin plate, and the thin plate is further fixed through the clamping bar and the lower plywood.
Through the clamping mechanism of the upper and lower clamping plates and clamping bars, the deflection of the thin plate during the shearing process is effectively avoided, ensuring the accuracy of the size of the cut thin plate. The design of the clamping strip makes replacement and maintenance easier.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plate shears, in particular to a material clamping mechanism of the plate shears. Background Art
[0002] A shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear a plate. It uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shearing force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size. The metal sheet placed on the shearing machine platform needs to be pushed under the blade step by step. At present, most of them are driven by a motor to rotate the screw, and the screw drives the push plate that is screwed to the screw and slides along the slide rail to move. The push plate then pushes the thin plate on the platform step by step to the blade for shearing. However, there is only a pushing relationship between the push plate and the thin plate, and the thin plate is not clamped, so the thin plate will be offset during the pushing or shearing process, which will cause the size of the cut thin plate to deviate.

[0016] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.
[0017] See also Figures 1 to 5The utility model provides a clamping mechanism of a shearing machine, which is installed on the shearing machine and includes a bottom plate 1. Slide blocks 2 are symmetrically arranged on the front and rear sides of the lower end of the bottom plate 1. The slide blocks are slidably matched on the slide rails of the shearing machine. A screw block 3 is arranged in the middle of the lower end of the bottom plate 1. The screw block is screwed to the screw on the shearing machine. The motor drives the screw block and the bottom plate to move along the slide rail through the screw, so as to push the clamped thin plate forward. A clamping plate assembly is equidistantly arranged above the bottom plate 1 along its length direction. The clamping plate assembly includes a lower clamping plate 4 and an upper clamping plate 5. Side plates for hingedly connecting the upper clamping plate 5 are vertically and symmetrically arranged on the front and rear sides of the upper end of the lower clamping plate 4. The lower clamping plate 4 is connected to the bottom plate 1 through a connecting block 11. A cylinder 6 is arranged upward at the lower end of the lower clamping plate 4. The left side of the upper splint 5 abuts against the piston rod of the cylinder 6, and a clamping strip 7 cooperating with the lower splint 4 is installed on the lower side of the right end of the upper splint 5. The right side of the upper splint is pressed down with the clamping strip, and the thin plate is clamped by the clamping strip and the lower splint. The clamping strip is easy to disassemble and replace, and the mechanism moves to the right. The thin plate placed on the platform falls on the right opening of the upper and lower splints and abuts against the side plate. The cylinder pushes the left side of the upper splint, so that the upper splint rotates, and the right side of the upper splint is pressed down to clamp the thin plate. Then the mechanism moves right step by step with the thin plate, and the shearing machine cuts the thin plate into thin plates of the same width for subsequent processing. After shearing, the piston rod of the cylinder moves down and resets, the upper splint is released and reversed and reset (the center of gravity of the upper splint is on the left), and then the mechanism moves left and resets.
[0018] See also Figure 1 , Figure 2 The upper side of the right end of the lower clamping plate 4 is provided with an inclined surface 4.1. The inclined surface is provided so that the thin plate placed on the platform can be conveniently placed on the right opening of the upper clamping plate and the lower clamping plate.
[0019] The left and right positions of the lower clamping plate and its upper part are adjusted through the adjustment hole. An adjustment hole 4.2 is longitudinally opened on the left side of the upper end of the lower clamping plate 4. The lower clamping plate 4 is locked to the connecting block 11 by a locking bolt passing through the adjustment hole 4.2. Loosen the locking bolt, adjust the left and right positions of the lower clamping plate and its upper part, and then tighten the locking bolt to lock the lower clamping plate.
[0020] Stabilizing blocks 8 are symmetrically arranged on the front and rear sides of the lower clamping plate 4, and horizontally arranged limiting bolts 9 are arranged on the stabilizing blocks 8 so as to be adjustable left and right. The limiting bolts can be adjusted left and right. When the mechanism moves right, the thin plate on the platform enters the right opening of the upper clamping plate and the lower clamping plate and abuts against the limiting bolts on the left, thereby limiting the position of the thin plate.
[0021] The upper side of the left end of the upper clamping plate 5 is provided with a counterweight 10. The counterweight is provided to increase the weight of the left side of the upper clamping plate so that the upper clamping plate can stably abut against the piston rod of the cylinder.
[0022] The above is only 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 technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
