The first and second hold-

down plates

304, 3015 are each shaped to accommodate the shape of the work piece 4 to be cut and cold-formed.

Before the preparation work, the cold-bending forming workpiece 4 is firstly placed on the electric conveying belt 3, the shape of the cold-bending forming workpiece 4 to be sheared is shown in the figure I, then the electric conveying belt 3 is controlled to work when the electric conveying belt 3 starts to drive the cold-bending forming workpiece 4 to gradually move from right to left, so that the cold-bending forming workpiece 4 smoothly passes through a space between two adjacent first pressing plates 304 and a second pressing plate 3015, meanwhile, according to the length of the cold-bending forming workpiece 4 to be sheared, the motor 209 is controlled to start to work, the motor 209 drives the first bevel gear 2010 to rotate, the first bevel gear 2010 drives the second bevel gear 2011 to rotate, then the two-way screw rod 206 is driven to rotate by the second bevel gear 2011, the two second connecting plates 207 are driven to move oppositely on the two polish rods 205 by the two-way screw rod 206, namely, the two cutters 208 are driven to move oppositely by the two second connecting plates 207, the distance between the two cutters 208 is consistent with the length of the cold-bending formed workpiece 4 to be cut, so that double-line cutting is realized, the original cutting rate is doubled, after the distance between the two cutters 208 is adjusted, the two cylinders 202 are controlled to start working, the two cylinders 202 drive the connecting frame 203 to move, the two second connecting plates 207 are driven by the connecting frame 203 to move, the two cutters 208 are further driven by the two second connecting plates 207 to cut the cold-bending formed workpiece 4, the cutting position of the cold-bending formed workpiece 4 is subjected to bending deformation due to stress on the cutting position of the cold-bending formed workpiece 4 in the cutting process, namely the cutting position of the cut cold-bending formed workpiece 4 is subjected to bending deformation, therefore, the cutting position of the cold-bending formed workpiece 4 needs to be limited and deformation prevention in the cutting process, and the thicknesses of the cold-bending formed workpiece 4 are different, during shearing, the two cutters 208 apply different forces to the shearing part of the cold roll forming workpiece 4, and the thickness of the cold roll forming workpiece 4 is different, so that the hardness of the cold roll forming workpiece 4 is different, and therefore, in the shearing process, when the shearing part of the cold roll forming workpiece 4 is limited, the pressure to be applied to the shearing part is different, the force is applied according to the stress capacity of the cold roll forming workpiece 4, and the shearing part of the cold roll forming workpiece 4 is ensured to be limited to prevent deformation.

Therefore, when the two cutters 208 shear the cold roll-formed workpiece 4, the two second connecting plates 207 synchronously drive the four third connecting plates 302 and the four racks 308 to move downwards, and further drive the two first pressing plates 304 to move downwards through the four third connecting plates 302, when the four racks 308 move downwards, based on the view from right to left, the four racks 308 drive the four flat gears 3010 to rotate clockwise, and further drive the four transmission shafts 309 to rotate clockwise through the four flat gears 3010, and then drive the four winding rollers 3011 to rotate clockwise through the four transmission shafts 309, when the four winding rollers 3011 rotate clockwise, the four winding rollers 3011 are connected with the adjacent first L-shaped plates 3012 through sliding ropes, when the four winding rollers 3011 rotate clockwise, the four sliding ropes are wound synchronously, when the four sliding ropes are wound, the four first L-shaped plates 3012 are synchronously pulled to slide upwards on the adjacent first round bars 3013, meanwhile, according to the difference in thickness of the cold-roll formed workpiece 4, the two first compression plates 304 and the two second compression plates 3015 exert different pressures on the two shearing portions of the cold-roll formed workpiece 4, that is, when the thickness of the cold-roll formed workpiece 4 is small, the pressures exerted on the two shearing portions of the cold-roll formed workpiece 4 by the two first compression plates 304 and the two second compression plates 3015 are small, and when the thickness of the cold-roll formed workpiece 4 is large, the pressures exerted on the two shearing portions of the cold-roll formed workpiece 4 by the two first compression plates 304 and the two second compression plates 3015 are large, thereby ensuring that the two shearing parts of the cold roll forming workpiece 4 can not be deformed and damaged.

Meanwhile, when the distance between the two cutters 208 is adjusted to meet the shearing requirement of the cold roll forming workpiece 4, the two second connecting plates 207 synchronously drive the four translation plates 303 to move through the two second connecting plates 207 in the moving process, and then the four square frames 307 are pushed to move through the four translation plates 303, namely the four sliding blocks 306 are driven by the four square frames 307 to slide in the two sliding rails 305, and the distance between the two cutters 208 is adjusted while the four sliding blocks slide.

When the cold roll forming workpiece 4 is sheared and reset, all parts are synchronously brought back to the original position, so that the two parts of the cold roll forming workpiece 4 sheared off by the two first pressing plates 304 and the two second pressing plates 3015 are automatically loosened, after the parts are loosened, under the action of gravity, the parts of the two cold roll forming workpieces 4 sheared off automatically fall to the fixed mounting frame 1, the fixed mounting frame 1 is set to be in a slope shape gradually reduced from the middle to two sides, the fixed mounting frame 1 is provided with the electric transmission rollers 2, the parts of the two cold roll forming workpieces 4 sheared off are separately transmitted through the electric transmission rollers 2, and then the cold roll forming workpieces are prevented from being accumulated, or the arrangement is messy, the manual work is required to be continuously coded, and the shearing speed is slowed down.

The guide plate 409 is provided in a downward slope shape as viewed from left to right.

The two second pressing plates 3015 are respectively provided with a sliding slot for the two first L-shaped plates 3012 to slide.

When the cold-roll formed workpiece 4 is conveyed between the two first pressing plates 304 and the two second pressing plates 3015, if the thickness of the cold-roll formed workpiece 4 is small, the cold-roll formed workpiece 4 is in a continuous conveying state, and the length of the cold-roll formed workpiece 4 to be cut is large, because the distance between the left end of the cold-roll formed workpiece 4 and the electric conveyor belt 3 is long, the left end of the cold-roll formed workpiece 4 automatically sinks under the action of gravity, so that the cold-roll formed workpiece 4 cannot smoothly pass through the space between the first pressing plate 304 and the second pressing plate 3015 on the left side, the device cannot rapidly and effectively cut the cold-roll formed workpiece 4 continuously, therefore, when the thickness of the cold-roll formed workpiece 4 is small and the length to be cut is large, the left end of the cold-roll formed workpiece 4 is in contact with the guide plate 409, so that the guide plate 409 is arranged in a downward slope shape when viewed from left to right, and then the cold-roll formed workpiece 4 is gradually supported by the guide plate 409, so that the left end of the cold-roll formed workpiece 4 smoothly passes through the space between the first pressing plate 304 and the second pressing plate 3015 on the left side, and the cold-roll formed workpiece 4 is continuously and efficiently sheared.

Meanwhile, when the cold roll forming workpiece 4 is sheared, burrs are generated at the sheared part of the cold roll forming workpiece 4, namely, a small-range deformation is generated, the burrs exist, if trimming is not performed after shearing, the burrs are easy to scratch workers, and extra cost and manpower are consumed for later processing, so in order to save cost, the workers are prevented from being scratched by the burrs at the sheared part of the cold roll forming workpiece 4, at the shearing moment of the cutter 208, the two second pressing plates 3015 synchronously move upwards, when the two second pressing plates 3015 move upwards, the two third L-shaped plates 403 are synchronously driven to move upwards, the two second wedge blocks 404 are driven to move upwards by the two third L-shaped plates 403, when the two second wedge blocks 404 move upwards, the two second wedge blocks 404 are extruded by the two first wedge blocks 402, so that the two second wedge blocks 404 are displaced, and then, the two third L-shaped plates 403 are driven to displace by the two second wedge-shaped blocks 404, that is, the two second pressing plates 3015 are driven by the two third L-shaped plates 403 to displace, when the two second pressing plates 3015 displace, the two second pressing plates 3015 simultaneously rub and remove burrs at two shearing positions of the cold-bending formed workpiece 4, and simultaneously trim the shearing positions to realize micro-shaping, so as to ensure that micro-deformation of the two shearing positions of the cold-bending formed workpiece 4 is reset, meanwhile, when the two second pressing plates 3015 displace, the two adjacent second round rods 407 synchronously slide on and stretch the adjacent second elastic elements 408, and when the two cutters 208 shear and complete resetting, the two second pressing plates 3015 automatically recover to the original positions under the resilience force of the four second elastic elements 408, so as to realize continuous deburring.
