Abstract
The brake flat hole pin temperature die device comprises an upper-die portion and a lower-die portion which are matched with each other. Die-locking die-sinking blocks are arranged on both sides of the upper-die portion and die-locking die-sinking cams which are matched with the die-locking die-sinking blocks are arranged on the upper portion of the lower-die portion. Slots used for tightly locking the die-locking die-sinking blocks are arranged on circumference surface of the die-locking die-sinking cams. Flat hole pins are extended out downward and vertically from the middle of the upper-die portion. The lower-die portion is provided with a lower-die upper-locating plate and a lower-die lower-locating plate which are disposed in an up-down mode and in clearance fit with each other. Brake flat hole pin insert holes are formed between the lower-die upper-locating plate and the lower-die lower-locating plate. The brake flat hole pin insert holes are matched with the flat hole pins through a punching hole channel which penetrates through the lower-die upper-locating plate vertically. The lower-die upper-locating plate is connected with a base which is arranged on the bottom of the lower-die portion through springs in an elastic mode. The lower-die lower-locating plate is fixedly connected with the base. The brake flat hole pin temperature die device has the advantages of simple die-locking and die-sinking, convenient to punch holes, eligible products quality and high processing efficiency.
Description
Technical field
The utility model relates to the technical field of the flushing device for toilet in the daily necessities, and warm die set is sold in the flat hole of especially a kind of braking.
Background technology
The flat hole circle pin of railway brake is on the irony cylinder between φ 20-φ 65, to process square hole in diameter, and this difficulty is bigger.Past all processes with line cutting in the flat hole in processing, but process velocity is slow, and cost is high, and is with other technologies, like the circular hole of drilling earlier, again towards flat hole or use broaching tool again, also less desirable with these methods.Cost is also very high, and the flat hole of product workpiece directly processes with punch press, and product thickness is thick; Flat hole dimension is little, and flat Kong Chongzhen has broken towards pin once getting on, and the product workpiece is with heating Wen Chong; The hole is to have rushed out; But the product temperature towards the time product flat hole upper part four change and follow flat hole also to fall in, cylinder also has been out of shape, and does not reach the product technology requirement at all.Put the product cylinder in the round nib into again towards flat hole, expand but product dashes the inside, back, the product workpiece is difficult to unload down, and warm punch die tool separates with the upper and lower; But locked mode die sinking difficulty is very big, and the product workpiece is put in the mould and fixed with two screw bolt and nut, and die sinking locked mode speed is too slow like this; After product workpiece heating back time in mould lengthens, the annealing of mould easy deformation, patrix is with rubber locked mode and discharging; Dark because of the flat hole depth of product, punch press pressure also strengthens, and is unworkable at all.
