Description

Progressive die series structure Technical Field The utility model relates to the field of machining, in particular to a serial structure of progressive dies. Background The body and shadow of the continuous die can be seen everywhere in the production of industries such as electronics, automobiles, household appliances and the like, and the continuous die participates in the production of various stamping parts with complex shapes. The working principle of the continuous die is that different forming stations are arranged in a set of die, blanks are fed into the die and are gradually stamped and deformed in sequence, and finally the required parts are obtained. The complicated condition of punching press zero portion is met, needs to design longer punching press deformation stroke, can lead to a template length not enough, needs the template to divide into the polylith, but uses adjacent two templates direct alignment, is difficult to guarantee the roughness and the uniformity that two templates are connected, influences the machining precision of punching press part. It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art. Disclosure of utility model Aiming at the defects of the prior art, the utility model discloses a serial structure of a progressive die. The technical scheme adopted by the utility model is as follows: The serial connection structure of the progressive die comprises a first connecting piece and a second connecting piece, wherein the first connecting piece and the second connecting piece are respectively arranged at the edges of the templates, when the two templates are connected, the first connecting piece and the second connecting piece are spliced into a whole, a first positioning groove is formed in the first connecting piece, a second positioning groove is formed in the second connecting piece, when the first connecting piece and the second connecting piece are spliced into a whole, the first positioning groove is communicated with the second positioning groove, and a connecting bolt is arranged between the first connecting piece and the second connecting piece and is positioned in the first positioning groove and the second positioning groove. Further, one end of the first positioning groove is provided with an accommodating cavity, and the head of the connecting bolt is clamped in the accommodating cavity. Further, the first connecting piece is provided with a plurality of first positioning screw holes, and the first positioning screw holes penetrate through the first connecting piece along the vertical direction. Further, a groove is formed in the side face of the first connecting piece. Further, the second connecting piece comprises a protruding portion and a step portion, the protruding portion and the step portion are integrally formed, and the locating groove is located on the protruding portion. Further, a plurality of positioning screw holes II which are arranged along the vertical direction are formed in the protruding portion. Further, a clamping block is arranged on the side face of the protruding portion and is matched with the groove, and when the first connecting piece is connected with the second connecting piece, the clamping block is inserted into the groove. Further, a plurality of positioning screw holes III are formed in the step portion, and the positioning screw holes III are arranged in the vertical direction. Further, one end of the connecting bolt far away from the head is in threaded connection with a nut, and the nut is abutted against the side face of the protruding portion. Further, the cross sections of the clamping blocks and the grooves are triangular. The beneficial effects of the utility model are as follows: 1. When two adjacent templates are butted, the first connecting piece and the second connecting piece are spliced, the first connecting piece and the second connecting piece are locked through the connecting bolt, and due to the limitation of the first connecting piece and the second connecting piece, the two templates are positioned in the same plane, so that the flatness and consistency of connection of the two templates are improved, the positioning error of the templates is reduced, and the part machining precision is improved. 2.
