Abstract
The utility model discloses a tube port blanking die and relates to a stamping die. The tube port blanking die comprises an upper die seat, a lower die seat and a die shank. A male die fixed seat is disposed on the lower surface of the upper die seat. A horizontal male die is arranged on the male die fixed seat. An arc-shaped cutting edge is disposed on the lower portion of the end face of a free end of the male die. A tube to be machined can be sleeved on the male die. A female die is disposed in a position of the lower die seat corresponding to the male die. An arc-shaped groove matched with the tube is disposed on the female die. The female die is provided with a triangle reinforcing rib. The lower die seat is provided with a guide plate for guiding the male die. The male die fixed seat is positioned between the guide plate and the female die. The tube port blanking die is high in production efficiency in the process of machining tube ports, low in work intensity, safe, reliable, and stable in product quality, and has great practicality.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of pipe end blanking die.
Background technology
Use metal pipe material in the design of product complete machine structure, to be widely used; And structure often has specific (special) requirements to the port shape of tubing, is circular arc such as the end that requires tubing, in the prior art generally is to adopt Milling Process, grinding or turning processing; Operating personnel will constantly locate tubing or cutter when adopting above-mentioned processing method to process tubing; Working strength is high, workload big, inefficiency, unstable product quality, and very dangerous, is easy to generate accident.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of pipe end blanking die, and production efficiency is high during the processing pipe end, and working strength is low, and is safe and reliable, and constant product quality is very practical.
The technical scheme of the utility model is: a kind of pipe end blanking die, comprise upper bolster, die shoe and die shank, and the upper bolster lower surface is provided with the punch holder; The punch holder is provided with the punch of level; The free-ended end face of punch bottom is a curved edge, and tubing to be processed can be enclosed within on the punch, and position corresponding with punch on the die shoe is provided with die; Have deep-slotted chip breaker on the die with the tubing coupling; Die is provided with the triangle ribs, and die shoe is provided with the guide plate into the punch guiding, and the punch fixed seating is between guide plate and die.
As preferably, punch adopts the GCr15 steel to process, and punch is provided with boss away from an end of cutting edge, and punch holder sidewall is provided with the groove with the boss coupling, and boss is fixedly connected in the groove through screw, and boss is provided with the location nail.
As preferably, upper bolster and die shoe adopt the Q235 steel to process, and position corresponding with the punch holder on the die shoe has through hole, and the projected area of punch holder on the through hole cross section is less than the cross-sectional area of through hole.
The beneficial effect of the utility model is: when using the utility model processing tubing, that pipe end is die-cut at twice.When for the first time die-cut, tubing is enclosed within on the punch, with location nail fixed length, die-cut Lower Half circular arc.When for the second time die-cut, with 180 ° of tubing upsets, with the pipe port arc surface location that is washed into; Just can accomplish whole stamping-out process, production efficiency is high, and whole process operation personnel only need twice location of tubing; Working strength is little, and constant product quality is very practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As a kind of embodiment of the utility model, as shown in Figure 1, a kind of pipe end blanking die comprises upper bolster 4, die shoe 9 and die shank 5; Upper bolster 4 lower surfaces are provided with punch holder 3, and punch holder 3 is provided with the punch 2 of level, and punch 2 free-ended end face bottoms are curved edge, and tubing 7 to be processed can be enclosed within on the punch 2; In the present embodiment, as preferably, punch 2 adopts the GCr15 steel to process; Intensity is high, frangible not, long service life.Punch 2 is provided with boss away from an end of cutting edge, and punch holder 3 sidewalls are provided with the groove with the boss coupling, and boss is fixedly connected in the groove through screw, and boss is provided with location nail 6, makes things convenient for the location of tubing 7.
Be provided with die 8 with punch 2 corresponding positions on the die shoe 9, have the deep-slotted chip breaker that matees with tubing 7 on the die 8, die 8 is provided with the triangle ribs, has guaranteed the intensity and the positional precision of die 8, is difficult for being dashed partially.Die shoe 9 is provided with the guide plate 1 into punch 2 guiding, and punch holder 3 is between guide plate 1 and die 8.
Before the beginning stamping-out, should punch 2 be adjusted to die 8 deep-slotted chip breakers and leave a more slightly position of tubing 7 wall thickness, so that tubing 7 is enclosed within on the punch 2.During mold work, that tubing 7 ports are die-cut at twice.When for the first time die-cut, tubing 7 is enclosed within on the punch 2, with location nail 6 fixed length, die-cut Lower Half circular arc.When for the second time die-cut,,, just can accomplish whole stamping-out process with the pipe port arc surface location that is washed into 180 ° of tubing 7 upsets.
More than a kind of pipe end blanking die that the utility model provided has been carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.Change and improvement to the utility model will be possible, and can not exceed design and the scope that accessory claim can be stipulated.
