Problems solved by technology
At present, in the processing of deep-drawing parts, because the material to be deep-drawn is relatively thin and soft, it is easy to be skewed and wrinkled during the drawing process, the positioning of continuous deep-drawing is inaccurate, and it is difficult for the punch to enter the product. There is a pressing problem in the deep-drawing process, and it is difficult to achieve the state of one deep-drawing operation, which reduces the product qualification rate, increases the cost of the enterprise, and is difficult to meet the market demand, which is not conducive to the development of the enterprise.

The invention relates to an integral type structure of location, pressing and discharging for deep-drawing moulds, which comprises an upper mould seat, a deep-drawing convex mould, a lower mould seat and a deep-drawing concave mould installed on the lower mould seat, wherein the deep-drawing convex mould and the lower mould seat are installed at the lower portion of the upper mould seat. A discharging plate is arranged between the deep-drawing convex mould and the deep-drawing concave mould, a first nitrogen spring is fixed on the upper mould seat, and a second nitrogen spring is fixed on the lower mould seat. A cantilever structure is further arranged between the first nitrogen spring and the second nitrogen spring and comprises a force transmission arm and a beam fixed at the upper end of the force transmission arm, and a location pressing cover is fixed on the beam. The integral type structure of location, pressing and discharging for deep-drawing moulds is simple in structure, can finish three procedures of location, pressing and discharging, has high working efficiency and finished product rate, greatly reduces production cost, and is convenient and reliable to use and long in service life.
Description
technical field [0001] The invention relates to a continuous die deep drawing process, in particular to an integrated structure of deep drawing die positioning, pressing and unloading. Background technique [0002] Deep drawing refers to the cold forming process that uses the movement of a punch to press a flat sheet into a mold cavity. At present, in the processing of deep-drawing parts, because the material to be deep-drawn is relatively thin and soft, it is easy to be skewed and wrinkled during the drawing process, the positioning of continuous deep-drawing is inaccurate, and it is difficult for the punch to enter the product. There is a pressing problem in the deep-drawing process, and it is difficult to achieve the state of completion of one-time deep-drawing operation, which reduces the product qualification rate, increases the cost of the enterprise, makes it difficult to meet the market demand, and is not conducive to the development of the enterprise. Therefore...
