Detailed Description

Make the technical problem, technical scheme and beneficial effect that the utility model solved are more clear and are understood, combine the embodiment below, it is right the utility model discloses further detailed description proceeds. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Examples

Shown in fig. 2 is a process for stamping 8 circular features in the ring side wall of fig. 1 in a continuous die, comprising an upper die bed 10, a lower die bed 20 and a synchronized sidepunch arrangement disposed between the two die beds. The device comprises an upper clamping plate 30, a stripper plate 40, a lower template 50 and a punching assembly, wherein the upper clamping plate is reversely locked at the bottom of an upper die base by adopting bolts, the upper clamping plate adopts a smaller-size template, and a nitrogen spring 60 which is arranged in the upper die base and drives the stripper plate to lift is positioned on the side surface of the upper clamping plate.

The punching assembly comprises a cylindrical fixing block 71, a punching female die 72, a driving block 73, a side sliding block 74 and a punch 75. The lower template is provided with a positioning part 51 and a plurality of sliding chutes 52 which are arrayed outside the positioning part at equal angles, the side sliding blocks are arranged in the sliding chutes, and springs 80 for resetting the side sliding blocks are arranged in the sliding chutes; one side of each side sliding block, which corresponds to the positioning part, is provided with a punch. Preferably, a through square hole is formed in the side surface of the side slider 74, and a cushion block 90 is arranged in the square hole in a penetrating manner to press the end portion of the punch head so as to fix the punch head in the side slider, so that the fixing manner does not occupy a large space, and the material of the cushion block can be selected according to the actual blanking force. The upper clamping plate is internally provided with driving blocks which correspond to the side sliding blocks one to one, the bottom of each driving block is an insertion rod, one side of each insertion rod is provided with a first inclined surface 731, and the slot of each side sliding block 74 is internally provided with a second inclined surface 741 matched with the first inclined surface. When the die is closed, the upper die moves downwards, and the inserted rod of the driving block is inserted into the slot of the side slide block in advance to complete the position guide between the driving block and the side slide block. And along with the descending continuation of the upper die, when the first inclined plane is completely attached to the second inclined plane, the side sliding block moves to a position close to the positioning part. When the mold is opened, the upper mold drives the driving block to move upwards, when the second inclined plane is completely separated from the first inclined plane, the pressure applied to the side sliding block disappears, and the side sliding block is reset under the action of the spring.

The cylindrical fixed block 71 is reversely locked in the stop plate 100 at the top of the stripper plate by equal-height screws, the side wall of the cylindrical fixed block is provided with chutes in one-to-one correspondence with the punches, each chute is internally provided with a punching die 72, the top of the punching die 72 is fixedly connected with the stripper plate 40, in a die opening state, the cylindrical fixed block 71 is positioned at the lowest position under the action of gravity, all the punching dies 72 are gathered towards the middle along the chutes, in a die closing state, the cylindrical fixed block receives thrust from the lower die plate 50, all the punching dies are outwards scattered along the chutes, and the profiling surface of the punching dies is attached to the inner wall of the ring-shaped piece. The punch is then moved into position, which cooperates with a corresponding punch cavity 72 to complete the die cut of the circular feature. Because the cylindrical fixed block is provided with a preset stroke, in the die opening process, the cylindrical fixed block moves upwards behind the punching female die, and therefore all the punching female dies after the die opening are still in an inward gathering state. Preferably, an elastic element is arranged between the cylindrical fixed block and the stop plate, and can assist the cylindrical fixed block to be at the lowest position in the mold opening state.

A plurality of sliding grooves and side sliding blocks are arranged in the lower template, and higher requirements are provided for the mountable space of the lower template. Because the side sliding block is internally provided with the slot, if the side sliding block is shorter, the slot is close to the edge, the strength of the side sliding block is possibly influenced to cause the local collapse of the side sliding block, and once the situation happens, the mould is very easy to explode, the normal production of products is influenced, and high mould maintenance cost is generated. Therefore, the implementation carries out reconstruction design on the structure of the side slide block on the basis of controlling the size of the side slide block. A reinforcing part is arranged on the inner wall of one side opposite to the punch 75 in the side slide block 74, and the bottom of the reinforcing part is connected with the inner wall of the side through a slope III 742; the driving block is provided with a position-giving part corresponding to the reinforcing part, and the bottom of the position-giving part is connected with the inserted rod through a four-inclined-surface 732. In a mold closing state, the three inclined surfaces 742 and the four inclined surfaces 732 keep a distance of 0.2-0.5mm, so that the inserted bar and the reinforcing part are not contacted all the time, the strength of the side sliding block corresponding to the slot is improved due to the arrangement of the reinforcing part, and the up-and-down movement of the inserted bar is not influenced. Preferably, the inclined angles of the first inclined plane, the second inclined plane, the third inclined plane and the fourth inclined plane are set to be consistent, so that the side sliding block can be conveniently machined.

What adopt between drive block and the side slider is inclined plane laminating structure, consequently at the beginning of mould examination mould, the adjustment is long required to the mounting height of drive block, sets up the hole of stepping down of the bolt department of corresponding fixed drive block in the upper die base, so under the condition of not dismantling the mould, alright completion drive block's debugging.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
