SU737075A1 - Die set for making square boxes - Google Patents

Description

The invention relates to the processing of metals by pressure, in particular to the equipment for the manufacture of boxes. The stamp dg1 of the preparation of rectangular boxes is known, comprising a punch and a die secured respectively on the upper and lower plates l. Special execution of the corner sections of the punches and dies allows the production of boxes from the pie of a coal blank (with uncut corner sections), but with low sides. Known stamp in which they can. boxes with an unlimited height of sides, containing a bending punch and a die with sharp corners 2, are to be manufactured. However, the known stamp is intended for the manufacture of boxes from cuts with cut corners. In order to get a box with corner folds, you must first shape them, for example, on one of the well-known stamps. In such a case, labor productivity decreases, the number of equipment and production facilities required increases.

The stamp also contains the top plate 9, on which the bending punch 10 is fixed, in the bayonet grooves II of which, having horizontal sections 12, a rocker arm 13 is installed, which has its skid t on the screw working surfaces 8 of the lower cams 7, and turning at a certain angle, comes out of the horizontal sections 12 of the grooves 11. At the end of the mold the crochet is in the vertical section of the groove 11 and the spring 14, triggered, raises the punch 15 to the upper position relative to the punch 10. The press slider continues to move downward, and the punch 10 pushes the semi-fabric into the lower portion of the die 2. The corner folds of the box take on the final shape and the side walls become vertical. When the press crawl moves up, the pusher 9 feeds the box up, the working surfaces 8 of the upper cams b, affect the ends of the rocker arm 13, delaying the lifting of the punch 15 and at the end of the stroke of the ram push the ends of the rocker arm into the horizontal sections 12 of the grooves 11, thereby cooked. stamp to the next duty cycle. If the box remains on the punch 10, the punch 15 will act as a stripper. DETAILED DESCRIPTION A stamp for making rectangular boxes containing a bending punch and a die, which is also so that, in order to increase labor productivity, it is equipped with a punch for forming folds of corners, mounted telescopically on the bending punch, placed on both sides of the punches by paired cams with working surfaces facing each other and interacting with cams rocker rigidly connected with a punch for forming the folds of the corners installed in the bending uansone bayonet grooves and spring-loaded in the vertical direction.
