Embodiment Construction

[0027] Examples see Figure 3-6 As shown, the mold for the stepped cylindrical part of the medium and thick plate is composed of three pairs of molds: the initial stretching die, the stretching shaping die and the punching die.

[0028] see image 3 , the primary stretching die is made up of stretching die upper die, stretching die lower die and stretching die stripping device, and described stretching die upper die comprises stretching die upper template 1 and is threadedly connected under the stretching die upper template The drawing die punch 3 on the surface, the drawing die lower die is connected on the drawing die die by the drawing die lower template 7, the drawing die die 2 that is threadedly connected on the drawing die lower template upper surface The positioning device is composed of, wherein the concave hole on the die die 2 of the drawing die is a straight hole.

[0029] The stretching die stripping device includes a stretching die stripping plate 4, a stretchin...

Abstract

The invention relates to a stepped cylindrical component die for a medium plate, which consists of a primary drawing die, a drawing dressing die and a punch die. The primary drawing die consists of an upper drawing die, a lower drawing die and a drawing die material returning device. The drawing dressing die consists of an upper dressing die, a lower dressing die and a dressing die material returning device. The punch die consists of an upper punch die, a lower punch die and a punch die guide pair. Only three sets of the stepped cylindrical component dies for the medium plate can press a die plate with middle thickness into a stepped cylindrical component. The three sets of dies have the advantages of simple structure, simple and easy manufacturing, convenient maintenance, reasonable layout, stable performance and long service life. The design standardization degree of the three sets of dies is high. Connecting bolts, material returning bolts, discharge rods and the like are all selected from standard components easily purchased on the market. The three sets of dies all adopt threaded connection and do not adopt the non-removable mode such as riveting, welding and the like so as to be convenient for later maintenance and convenient disassembling.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for pressing a mold plate into a stepped cylindrical shape. Background technique [0002] The process of manufacturing stepped cylindrical parts with medium and thick plates is relatively complicated, generally four or more steps are required, and four or more sets of molds are required, and each set of molds is very complicated, especially The punching pattern of the punching die used in the punching step is complicated, which affects the quality of the part and reduces the life of the die. In addition, the overall assembly of the existing mold is very difficult, the manufacturing and maintenance costs of the mold are high, but the production efficiency of the mold is very low, so it is urgent to improve. Contents of the invention [0003] The purpose of the present invention is to provide a mold for stepped cylindrical parts of medium and thick plates, which solves the technical problem that...
