Description

Deep drawing rotary cutting die

technical field

The utility model relates to a stamping die, in particular to a rotary cutting die for drawing parts.

Background technique

With the rapid development of science and technology, metal stamping parts are widely used in various industries, and the requirements for product quality and size are becoming more and more stringent. The traditional processing technology of some products can no longer meet the requirements. Among them, hardware stretching products are particularly prominent. During the stretching process, due to the anisotropy of the material, uneven thickness, inaccurate positioning or uneven gap between the drawing dies, the top of the drawn workpiece will be irregular. . For parts that require flat and beautiful ends, it is necessary to supplement the edge trimming process. The traditional simple trimming method (flashing of simple molds or trimming on lathes and spinning machines) cannot meet the tolerance requirements and the work efficiency is low. However, the desired effect can be achieved by using a rotary cutting mold with high processing precision.

Utility model content

The middle part of the rocker slider has a rectangular through groove, the four inner side walls of the through groove are guide rail surfaces, and its cross section is a trapezoidal sawtooth surface.

The left and right inner sidewalls of the through groove are opposite, and in the horizontal direction, the protrusions and depressions of the left inner sidewall are opposite to the depressions and protrusions of the right inner sidewall.

The front and rear inner sidewalls of the through groove are opposite, and in the horizontal direction, the protrusions and depressions in the front inner sidewall are opposite to the depressions and protrusions in the rear inner sidewall.

After the above scheme is adopted, since the utility model includes a rocker block and a rocker slider, the rocker block can move horizontally and vertically along the guide rails on the inner wall of the rectangular channel of the rocker slider, and the entire product can be realized in one stamping process. The shape is cut, the cut is smooth and beautiful, and the appearance of deep-drawing products is improved, and the production efficiency is high.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Detailed ways

As shown in Figures 1-3, the utility model is a rotary cutting die for drawing parts, including an upper template 1, an upper module 2, a punch 3, an upper imitation-shaped pressing plate 4, a limit column 5, and a die 6. Bottom imitation shaped binder plate 7, shaker block 8, shaker slider 9, lower module 10, lower template 11, ejector rod 12, top plate 13, rubber pad 14, splint 15, guide post 16, guide sleeve 17 .

The upper end surface of the upper module 2 is fixed on the upper template 1, the upper part of the punch 3 and the upper part of the limit column 5 are fixedly inserted in the upper module 2, and the upper imitation-shaped binder plate 4 is fixedly installed on the top of the punch 4.

The upper end of the die 6 is opposite to the punch 3 and cooperates with the punch 3, the lower end of the die 6 is fixedly connected with the rocker block 8, and the lower imitation-shaped binder plate 4 is set in the hole of the die. Among them, the top surface of the die 6 can be limited by abutting against the lower end of the limiting column 5, and the lower imitation-shaped clamping plate 4 and the upper imitation-shaped clamping plate 4 firmly clamp the product 100 together.

The rocker block 8 is movably nested in the rocker slider 9, and the rocker slider 9 is nested in the lower module 10 and fixedly installed on the lower template 11, and the lower end of the rocker block 8 is against the top of the push rod 12. . As shown in FIG. 3 , the middle part of the rocker slider 9 has a rectangular through groove 91 , the four inner side walls of the through groove 91 are guide rail surfaces, and its cross section is a trapezoidal sawtooth surface. The left and right inner sidewalls of the through groove 91 are opposite, and in the horizontal direction, the protrusion and depression of the left inner sidewall 911 are opposite to the depressions and protrusions of the right inner sidewall 912 . The front and rear inner sidewalls of the through groove 91 are opposite, and in the horizontal direction, the protrusions and depressions in the front inner sidewall 913 are opposite to the depressions and protrusions in the rear inner sidewall 914 .
