Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2 and 4, in the present embodiment, a mechanical manufacturing stamping device is provided, which includes a base 1, a worktable 2 and a first motor 5 are fixed on the base 1, the first motor 5 is located at one side of the worktable 2, a chute is formed at the top of the worktable 2, an output shaft of the first motor 5 is fixedly connected to a first lead screw 6, and one end of the first lead screw 6, which is away from the first motor 5, penetrates through a carrying platform 7 and extends into the chute; and a hydraulic cylinder 3 and a feed hopper 4 are fixed above the workbench 2 through a frame, a pressing plate 14 is fixedly connected to the bottom of the hydraulic cylinder 3, and the hydraulic cylinder 3 and the feed hopper 4 are sequentially arranged along the moving direction of the carrier table 7.

The top of the carrier 7 is provided with a molding cavity, the bottom of the molding cavity is fixed with a spring 19, and the top of the spring 19 is fixed with a movable plate 11.

From the above, the stamping principle of the integral stamping device is as follows:

automatic discharging: treat that the work piece of punching press piles up and places in feeder hopper 4, when carrying out whole stamping device's feeding, start first motor 5, first motor 5 output shaft orders about first lead screw 6 and rotates to drive microscope carrier 7 along first lead screw 6 axial displacement, when microscope carrier 7 removed under feeder hopper 4, feeder hopper 4 carries out automatic blanking, make its inside work piece (the work piece of below) that piles up fall to on the fly leaf 11, first motor 5 of reversal then, move through the reseing of microscope carrier 7 and make the work piece transport under the pneumatic cylinder 3, accomplish autoloading.

Stamping: the hydraulic cylinder 3 is started, the pressing plate 14 fixedly connected with the bottom of the hydraulic cylinder 3 is driven to descend, so that a workpiece placed on the surface of the carrying platform 7 is punched, and a forming cavity is formed in the carrying platform 7, so that part of the workpiece is punched into the forming cavity by the pressing plate 14, and the punching deformation of the workpiece is realized; during this pressing, the depression of the presser plate 14 forces the movable plate 11 towards the bottom of the forming cavity and progressively compresses the spring 19.

Discharging: the hydraulic cylinder 3 drives the pressing plate 14 to move upwards, the spring 19 rebounds to drive the movable plate 11 to ascend, the workpiece ascends along with the movable plate, and therefore the punch-formed workpiece is automatically separated from the forming cavity, and discharging is completed.

Specifically, with respect to the automatic feeding, refer to fig. 3:

the mounting groove has been seted up to feeder hopper 4 bottom, and slidable mounting has baffle 12 in the mounting groove, and the one end fixedly connected with connecting rod 13 of baffle 12, and connecting rod 13 deviates from the one end fixed connection of baffle 12 on microscope carrier 7.

The size of the carrier 7 is larger than that of the feed hopper 4, one side of the baffle plate 12, which is far away from the connecting rod 13, horizontally extends above the carrier 7, and the baffle plate 12 is positioned on one side of the movable plate 11.

From the above, the principle of automatic feeding is as follows:

the carrier 7 moves towards the lower part of the feed hopper 4, so that the connecting rod 13 moves along with the carrier, the baffle plate 12 is driven to move synchronously, when the carrier 7 moves to the position under the feed hopper 4, the baffle plate 12 is completely retreated from the mounting groove of the feed hopper 4, a workpiece falls on the movable plate 11 along with the baffle plate, the first motor 5 is reversely rotated at the moment to drive the first lead screw 6 to reversely rotate, the carrier 7 moves towards the lower part of the hydraulic cylinder 3 along with the baffle plate 12, and meanwhile, the baffle plate 12 also moves back along with the baffle plate, so that automatic feeding is realized.

Further, while the automatic feeding is realized, the workpiece falling on the movable plate 11 is clamped by a clamping device mounted on the stage 7, and the clamping device is shown in fig. 4:

the second motors 8 are fixed on two sides of the carrier 7, two grooves are symmetrically formed in the top of the carrier 7, a second lead screw 9 is rotatably mounted in each groove, the second lead screws 9 are driven to rotate through the second motors 8, and the two second lead screws 9 are respectively in threaded connection with a first clamping plate 10 and a second clamping plate 15.

The one end of first splint 10 and second splint 15 all is fixed with third motor 17, and the guide slot has all been seted up to first splint 10 and second splint 15 inside, and all rotates in two guide slots and installs third lead screw 16, and third lead screw 16 passes through the drive of third motor 17 rotatory, and all is equipped with on every third lead screw 16 and revolves to two opposite screw thread portions, all closes L clamp plate 18 on two screw thread portions soon.

From the above, the principle of the clamping device is:

clamping workpiece

The second motors 8 on the two sides of the carrier 7 are started to drive the second lead screws 9 to rotate, so that the first clamping plates 10 and the second clamping plates 15 are driven to approach or separate from each other, and then the third motors 17 fixed at one ends of the first clamping plates 10 and the second clamping plates 15 are started to drive the third lead screws 16 to rotate, so that the two L-shaped clamping plates 18 on each third lead screw 16 are driven to move relatively. Taking the example of mutual approach, the first clamping plate 10 and the second clamping plate 15 approach each other and approach the surface of the workpiece, at this time, the four L-shaped clamping plates 18 approach each other and cling to the surface of the workpiece, and the first clamping plate 10 and the second clamping plate 15 continue to approach each other, so that both sides of the four L-shaped clamping plates 18 cling to the surface of the workpiece, thereby achieving the position fixing and clamping of the workpiece.

Loosening workpieces

The third motor 17 rotates reversely to drive the third lead screw 16 to rotate reversely, so as to drive the two L-shaped clamping plates 18 on each third lead screw 16 to be away from each other, and at the moment, the second motor 8 also rotates reversely to drive the second lead screw 9 to rotate reversely, so as to drive the first clamping plate 10 and the second clamping plate 15 to be away from each other, so that the two sides of the four L-shaped clamping plates 18 are away from the surface of the workpiece, and the workpiece is loosened.
