As an embodiment of the present invention, as shown in fig. 8, the limiting blocks 24 and the limiting grooves 26 are correspondingly matched with each other, the number of the limiting blocks is four, and the limiting blocks are distributed annularly and equidistantly with the center of the output shaft of the motor 22 as a midpoint, the length of the limiting blocks 24 is smaller than that of the limiting grooves 26, and an extension spring 28 is fixedly connected between the upper end of the inner surface of the extension groove 27 and the output shaft of the motor 22.

Through adopting above-mentioned technical scheme, receive when the work piece and strike and make extrusion piece 33 move down and force grip block 311 to accomplish the back of carrying out the centre gripping to the work piece, the downward movement can appear in the work piece, and at this moment, runner 25 moves down along stopper 24 through spacing groove 26 is synchronous to guarantee that the work piece is same horizontal line all the time, avoid the work piece because move down the condition emergence that the position skew appears, can improve the device autoloading's operation effect effectively through this technical scheme, runner 25 resumes initial condition under the spring action of expanding spring 28 after the punching press is accomplished.

The working principle is as follows: when a workpiece is stamped by external force, the workpiece forces two groups of squeezing blocks 33 to move downwards, and the clamping plates 311 move along the guide grooves 5 under the mutual matching of the squeezing blocks 33 and the moving block 35, so that the workpiece is tightened, the workpiece is prevented from shifting when being stamped, the precision of processing the workpiece is improved, the two groups of squeezing blocks 33 are connected through the connecting rods 34, so that the two groups of squeezing blocks 33 keep synchronous when moving downwards by the external force, the condition that the two groups of clamping plates 311 have uneven force due to uneven force is avoided, the squeezing blocks 33 move downwards along the sliding grooves 331, the inclined surfaces of the squeezing blocks 33 are in contact with the inclined surfaces of the moving block 35, and the moving block 35 is forced to bear horizontal acting force and move along the horizontal direction of the inclined surfaces of the squeezing blocks 33 because the angle of the inclined surfaces of the squeezing blocks 33 is complementary with the angle of the inclined surfaces of the moving block 35, the technical scheme is that the workpiece can be automatically clamped and fixed when being stamped by the technical scheme, so that the work piece is greatly improved in working efficiency, due to frequent stamping and shearing of the workpiece, scraps generated after stamping and shearing can be remained on the surface of the bearing table 3 and can enter the guide groove 5 to obstruct the movement of the clamping plate 311, when in work, the inner surface of the guide groove 5 is provided with the second groove 4, because the bearing table 3 is made of metal materials, the magnet 41 in the second groove 4 can be attracted with the scraps, the collecting frame 42 is movably connected with the guide groove 5 through the mutual matching of the magnet 41 and the groove II 4, meanwhile, the two ends of the collecting frame 42 are movably connected with the clamping plate 311 through the mutual matching of the clamping block 43 and the clamping groove 46, the collecting frame 42 can collect the surface debris into the collecting frame 42 due to the fact that the width of the collecting frame 42 is equal to the width of the guide groove 5, the debris is prevented from influencing the normal movement of the guide block 39, the traction spring 44 is fixedly connected between the two groups of collecting frames 42, the collecting frame 42 is folded towards the middle position when the clamping plate 311 clamps the workpiece, the collecting frame 42 with the splayed structure design is beneficial to the collection of the debris, the collected debris is collected to the two ends of the collecting frame 42, meanwhile, the gap generated when the two groups of collecting frames 42 are mutually closed is compensated through the elasticity of the rubber gasket 45, the probability that the debris enters the guide groove 5 is reduced, the clamping block 43 moves downwards along the clamping groove 46 when the two groups of collecting frame 42 are folded, when the collecting frame 42 needs to be cleaned, a user manually draws the collecting frame in and then takes out the collecting frame to clean the interior of the collecting frame, the fragments can be effectively collected through the technical scheme, the fragments are prevented from entering the guide groove 5, the user inserts the sheet-shaped workpiece into the guide frame 2 and contacts with the T-shaped end face of the rotating wheel 25 with the T-shaped structure design, the motor 22 drives the two groups of rotating wheels 25 to rotate through the output shaft so as to finish automatic feeding, the longitudinal section of the rotating wheel 25 is in the T-shaped structure design and is beneficial to placing of a punched workpiece, the rubber bump 29 arranged on the annular outer surface of the rotating wheel 25 can increase the friction force between the workpiece and the rotating wheel 25 so as to avoid the occurrence of slippage between the rotating wheel 25 and the workpiece, when the workpiece is impacted, the extrusion block 33 moves downwards to force the clamping plate 311 to clamp the workpiece, the workpiece can move downwards, and at the rotating wheel 25 synchronously moves downwards along the limiting block 24 through the limiting groove 26, therefore, the workpieces are always in the same horizontal line, the situation that the workpieces shift due to downward movement is avoided, the running effect of automatic feeding of the device can be effectively improved through the technical scheme, and the rotating wheel 25 is restored to the initial state under the elastic force of the telescopic spring 28 after punching is finished.
