SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a marine tank body elasticity festival mold processing of easily drawing of patterns.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a boats and ships jar body elastic joint mold processing of easy drawing of patterns, is including the last mould of the type of falling L, goes up the vertical section lower extreme of mould and is equipped with U type drift, is connected through the fillet between horizontal segment and the vertical section, the lower mould is equipped with the U type groove that matches with U type drift, and the front and back end of U type tank bottom portion is seted up flutedly, and U type groove open-ended both sides rigid coupling respectively has first, second cushion, and one side of first, the nearly U type groove end of second cushion aligns with U type groove opening, and first, second cushion upper portion is equipped with the chamfer that corresponds with the fillet, and second cushion top is provided with detachable third cushion. Before the punching press, install the third cushion in the top of second cushion, place processing plate on the lower mould, utilize last mould one-time stamping forming, after the punching press is accomplished, dismantle the third cushion, will go up the mould lifting, stretch into the recess of U type tank bottom portion with the crowbar, easily throw off the elastic joint from the mould, and simultaneously, in stamping process, processing plate easily bends and peels, the recess of U type tank bottom portion has the cushioning effect, in U type tank opening both sides rigid coupling cushion, because in the elastic joint course of working, U type tank opening both sides atress is the biggest, the cushion of rigid coupling high strength can prevent that the mould is impaired in the course of working.

Preferably, both side edges of the U-shaped punch head are internally contracted by 2-3 mm. The U-shaped punch is internally contracted at two sides to provide more deformation space for processing the plate.

Preferably, chamfers are arranged on the upper portion and the lower portion of one side, close to the U-shaped groove end, of the third cushion block. Set up the chamfer and prevent that the staff from by the edges and corners fish tail when the dismouting.

Preferably, the first cushion block and the second cushion block are made of P690 steel. The P690 steel has higher strength than the processed plate, can not deform when bearing stamping, and meets the production requirements of processing dies.

Preferably, symmetrical lifting lugs are arranged at the front end and the rear end of the upper die. The upper die can be conveniently hoisted in use.

Preferably, a C-shaped handle is fixedly connected to the top end of the third cushion block. The third cushion block is convenient to mount and dismount.

Compared with the prior art, the utility model, have following advantage:

the elastic section of the ship tank body can be produced in large batch, is simple to produce, simple to manufacture, easy and simple to operate and convenient to popularize and use, improves the efficiency of autonomous production and processing, needs not to adopt high-strength materials to the whole die by fixedly connecting cushion blocks on two sides of an opening of a lower die U-shaped groove, saves the production cost of the die, and reduces the expenditure of outsourcing and processing tools by using the die for production.
