Embodiment Construction

[0015] The following will be further described in conjunction with the accompanying drawings, not to limit the scope of the present invention.

[0016] see figure 1 and figure 2 Shown, the present invention comprises upper formwork 3, punch and lower formwork 8, is fixed with mold handle 1, spring 2, punch fixed plate 4, binder plate 5 on upper formwork 3, fixes convex mold in described fixed plate Dies, on the lower template 8 are provided with a floating tip 6, a die 7 and a material guide plate 10, and on the die 7 are provided with an initial positioning pin 11, a side edge 12 and a step positioning block 13. The guide post guide sleeve 9 is arranged on the upper template 3. When working, put the workpiece between the two material guide plates 10 and push it forward to the initial positioning pin 11. When the upper mold is pressed in, the punching is completed; Push forward to the step distance positioning block 13, which is exactly one step distance. When the upper die...

Abstract

The invention relates to a continuous punching and hole flanging blanking die which comprises an upper die plate, a male die and a lower die plate. The continuous punching and hole flanging blanking die is characterized in that the upper die plate is fixedly connected with a male die fixing plate and a material pressing plate, the male die is pressed into the male die fixing plate, a spring is placed between the fixing plate and the material pressing plate, and a guide needle is arranged in the material pressing plate; the lower die plate is fixedly connected with a female die and material guiding plates, and the female die is provided with side edges, step locating blocks, floating pins, an initial locating pin and a punching and hole flanging blanking cavity. According to the die, common equipment is used for production, the cost of investment of the equipment is greatly lowered, the utilization rate of the equipment is improved, and working efficiency and product precision can be improved substantially.

Description

technical field [0001] The invention relates to a mold, in particular to a continuous mold for punching, reversing and blanking. Background technique [0002] At present, for the production of line cards in China, two sets of single dies for blanking and punching are generally used. The disadvantages are: 1) occupying equipment, low utilization rate of equipment, low efficiency, and high cost; 2) workpiece alignment, accuracy, etc. The requirements are high and it is difficult to meet the requirements; 3) An additional worker is required during operation, and the cycle of mold replacement and debugging is long. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and proposes a punching, reversing and blanking continuous mold, which can be used universally in the field of blanking and punching, has a small footprint, low mold cost, and high work efficiency; the product Good quality, stable angle and practical. [0004] The...
