Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 5, a forming and blanking integrated die includes an upper die structure 1 and a lower die structure 2, where the upper die structure 1 and the lower die structure 2 can be separated from each other or pressed together, and a floating die 3 and a supporting beam 4 are disposed on a surface of the upper die structure 1;

the number of the two supporting beams 4 is two, the two supporting beams 4 penetrate through the other side of the upper die structure 1 from one side, an upper height limiting block 401 and a lower height limiting block 402 are arranged at two ends of each supporting beam 4, and a cylinder controls the upper height limiting block 401 and the lower height limiting block 402 to extend out or return, so that the supporting beams 4 are driven to float up and down. And the forming and punching are realized through mechanical linkage.

Go up high stopper 401 and when low height stopper 402 stretches out, it is spacing to supporting beam 4, supporting beam 4 traveles downwards, it is spacing to decurrent minimum with floating mould 3, it is big to recycle product face stress area when shaping, the principle that mould pressing pressure is little relatively, it is spacing to carry out the whole support to the 3 backs of floating mould 4, nitrogen spring receives the influence of pressure during the compound die, produce thrust down to supporting beam 4 and floating mould 3, make floating mould 3 compress tightly the shaping, realize first step product forming function.

Two nitrogen springs 403 arranged at intervals are arranged on each supporting cross beam 4, and the floating die 3 can be supported by the nitrogen springs 403.

When the upper die structure 1 and the lower die structure 2 are closed, the nitrogen spring 403 is stressed, so that the supporting beam 4 moves downwards to enable the floating die 3 to be pressed and molded through mechanical movement.

The nitrogen spring 402 is mounted to the supporting beam 4, the supporting beam 4 is positioned through the upper height limiting block 401 and the lower height limiting block 402, the stress of the nitrogen spring 402 is transmitted to the supporting beam 4 when the upper die structure 1 is pressed downwards, the supporting beam 4 floats downwards to press the floating die 3, at the moment, the floating die 3 is guided by the tight fit of the guide rod 201 and the guide sleeve hole, and when the upper die structure 1 descends to the right position, one-step forming is completed when die assembly is carried out;

the two supporting beams 4 are arranged at intervals.

A circulating track 301 is arranged inside the floating die 3, a water inlet is formed in one end of the circulating track 301, and a water outlet is formed in the other end of the circulating track 301.

The circulating rail 301 of the floating die 3 can play a cooling role, and can cool a die to be stamped.

The water inlet is connected with the cooling end of the equipment, and the water outlet is connected with the water outlet end of the equipment.

The upper height limiting block 401 and the lower height limiting block 402 are respectively arranged at the upper end and the lower end of the supporting beam 4.

The upper height limiting block 401 and the lower height limiting block 402 are arranged along the length direction of the upper die structure 1 and face opposite directions.

The surface of the upper die structure 1 is provided with a plurality of guide rods 201.

Punching principle:

the upper height limiting block 401 and the lower height limiting block 402 return, the floating die 3 returns to the original point, and blanking is performed through direct cutting.

After the shaping, the signal mould is given to equipment, go up high stopper 401 and lower high stopper 402 and return through cylinder control, go up mould structure 1 simultaneously and lift a little upwards, release nitrogen spring 403 pressure, make the unsteady mould 3 get back to the initial point (because of the hole site and when the required power of shearing of periphery is greater than the shaping, the original point state must be got back to the mould state, just can bear the maximum force), go up mould structure 1 rethread equipment and push down the signal, the direct downward travel once more of whole mould, cut product hole site and periphery, realize the second portion shear function.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
