Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1-4, including the splint 9 that is used for installing mould 12 and the workstation 1 that is used for placing lower mould 13, be equipped with baffle 2 on workstation 1, set up conveyer on baffle 2, conveyer includes a plurality of hobbing 21 and a plurality of gyro wheel 3, hobbing 21 rotates to be connected on baffle 2 and for the meshing connection between the hobbing 21, sets up on alternate spaced hobbing 21 gyro wheel 3, conveyer sets up two sets of about at least workstation 1 one side.

Two baffle plates 2 are arranged on one side of a workbench 1, hobbing teeth 21 in a conveying device are rotatably connected to the baffle plates 2, in the embodiment, the number of the hobbing teeth 21 is 7, the hobbing teeth 21 with the odd number are provided with rollers 3, the other side of each roller 3 is rotatably arranged on the baffle plate 2 on the other side, the thickness of the hobbing teeth 21 with the even number is smaller than that of the hobbing teeth 21 with the odd number, namely, the hobbing teeth 21 with the even number do not contact with the rollers 3, at least two groups of conveying devices are arranged above and below the baffle plates 2, and the hobbing teeth 21 with the upper row and the lower row are respectively connected with a rotating motor, so long as the rotation directions of the idler wheel 3 on the upper side and the idler wheel 3 on the lower side are opposite.

A splint 9 for installing mould 12 passes through elastic component 11 and connects sand grip 10, sand grip 10 will set up the first rack 5 connection in workstation 1 both sides, first gear 4 is connected in first rack 5 meshing, first gear 5 sets up the inboard of baffle 2, and two sets of first gear 5 pass through connecting axle 14 and connect, and second gear 6 is also connected by connecting axle 14 the 2 outsides of baffle, and mesh in 6 below of two sets of second gear and connect second rack 7, second rack 7 sliding connection be in the 2 outsides of baffle.

One side of the second rack 7 is connected through a connecting rod 8, a brush 81 is arranged above the lower die 13 and below the connecting rod 8, the use method is that the rotating motor is started, the roller 3 is reversely rotated by the upper-row conveying device and the lower-row conveying device, the plate material moves to a workbench under the rotation of the roller 3 with high friction force, when the plate material moves to a required position, a punching part can downwards move the clamping plate 9 and the upper die 12 on the clamping plate with large force, the second rack 7 downwards moves under the driving of the clamping plate 9 to drive the first gear which is coaxially connected to rotate, the brush 81 is pushed to the left side of the workbench 1 by the first rack 5, when the first rack 5 props against the workbench 1, the upper die 12 continues to downwards under the action of the elastic piece 11, when the punching is completed, the upper die 12 rises, and the second rack 7 continues to upwards move when the elastic piece 11 is recovered, namely, the brush 81 moves rightwards to sweep away the waste residue remained on the lower die 13, and the number of turns of the rotation of the motor can be controlled effectively to control the feeding amount each time.
