Description

(5) METHOD OF MANUFACTURING HOLES WITH HOLES

Claims (2)

  1. The invention relates to forging press manufacturing, in particular to the production of forgings with a hole, performed in linings on presses and hammers. A known method of manufacturing forgings with a sleeve-type hole with a flange or shoulder, including piercing the hole 1 from the flange side t. A disadvantage of the known method is that at the moment of the piercing of the piercing when making the hole djy | .g-0.5, a hub is obtained on the edge x holes as a result of the flow of the flange heated from the pins to the periphery. The closest in technical essence and effect achieved to the invention is a method for producing hollow parts with a flange or a flange t2. The disadvantage of this method is that it can only be used for parts with a blind hole. In addition, to make a hole in a part by stamping it is necessary to have a special shape corresponding to the external contour of the lanz, and an annular punch. The purpose of the invention is to reduce the labor intensity by reducing the machining allowances in forgings. This goal is achieved by the fact that the hole is pierced from the side of the hub with a diameter of more than 0.5 of the hub diameter. The drawing shows the sequence of operations in the implementation of the method. The method of making the hole in the sleeve type forgings with a flange or shoulder is carried out as follows. The heated billet 1 is inserted into the backing ring 2 and is deposited to a forging height H (see drawing). 39 Do not remove the ring 2, turn the workpiece 1 on. 180 ° with an anise flange and starting the flashing of the hole by stitching 3 from the hub side, while going deeper by 2/3 H in total workpiece 1 (Fig. 1b). Then, the workpiece 1 is returned to its original position, flanged up, and from the hub side, ring k is inserted for knocking 3 with another piercing (not shown) from the flange side (Fig. 1c). After that, the workpiece 1 is knocked out of the ring 2, is right in height, and a flange is rolled in diameter (Fig. 1g). The method for making holes in the forgings Tffna of the sleeve with a flange or shoulder makes it possible to reduce the pipe. % and reduce machining allowances by ZQkQ%. Formula of the Invention The method is made of forgings with a hub-type hole with a flange, including slugging of the forging and piercing of the hole, characterized in that in order to reduce the labor intensity of piercing the hole and reduce the allowances for machining, hole drilling is carried out from the side of the hub with a diameter of piercing, large noi half of the diameter of the hub.
