Abstract

The utility model provides a pipe fitting pipe end shaping self-centering flanging die. The die comprises a press machine, wherein an automatic centering head is sleeved at the top of the press machine through a nut, a conical flanging die head is connected with the front end of the conical flanging die head in a clamping mode movably, the corresponding conical flanging die head a positioning clamp is arranged corresponding to the conical flanging die head, an end port of the positioning clamp is a concave conical surface, and a conical shape of the conical flanging die head is matched with the concave conical surface of the end port of the positioning clamp; and the angle of the conical shape of the conical flanging die head and the concave conical surface of the end port of the positioning clamp ranges between 70 degrees and 90 degrees. The flanging die is suitable for pipe end flanging forming processing of pipe fittings of an engine, flanging can be achieved at an angle ranging between 70 degrees and 90 degrees, the conical flanging die head is matched with the concave conical surface of the end port of the positioning clamp, the flanging effect is achieved through automatic alignment, automatic centering and automatic adjustment, and the flanging die is simple in structure, economical and practical.

Description

Pipe fitting tube-end forming self-centering turned welt mould

Technical field

The utility model relates to automobile engine pipe fitting tube-end forming technology, specifically is the self-centering turned welt mould of pipe fitting tube-end forming.

Background technology

Usually adopt the standard pipe end shaper to cooperate high-precision mold to be shaped for engine pipe fitting pipe end turned welt shaping oil pipe at present, this process is simple, but higher to equipment and Mould Machining precision prescribed, ordinary disbursements is bigger.

Summary of the invention

The utility model makes the general precision hydraulic press cooperate mould in order to reduce cost, and realizes that the pipe fitting turned welt is shaped, a kind of pipe fitting tube-end forming self-centering turned welt mould of special proposition.

The technical scheme of the utility model does for this reason; Pipe fitting tube-end forming self-centering turned welt mould comprises a forcing press, and it is characterized in that: the top at forcing press is provided with the self-centering head through nut sleeve; The front end active card of self-centering head is connected to taper flanging die head; Corresponding taper flanging die head is provided with a positioning fixture, and the port of positioning fixture is the concave cone face, and the taper of taper flanging die head and the concave cone face of positioning fixture port cooperate.

Improvement to such scheme is: the angle of the taper of taper flanging die head and the concave cone face of positioning fixture port is 70 ° ~ 90 °.

Beneficial effect:

The processing that the utility model apply engine pipe fitting pipe end turned welt is shaped. can flange to 70 ° ~ 90 ° arbitrarily angled; Through taper flanging die head and the cooperation of positioning fixture port concave cone face; Automatic capturing, self-centering, the automatic effect that reaches flange of regulating, simple in structure economic and practical.

Description of drawings

Fig. 1 is the structural representation of the utility model.

1 is nut sleeve among the figure, the 2nd, and self-centering head, the 3rd, taper flanging die head, the 4th, positioning fixture, the 5th, concave cone face, the 6th, pipe fitting, the 7th, forcing press.

The specific embodiment

The utility model is as shown in Figure 1.

Pipe fitting tube-end forming self-centering turned welt mould; Comprise a forcing press 7; Be provided with self-centering 2 on the top of forcing press 7 through nut sleeve 1, the front end active card of self-centering 2 is connected to taper flanging die head 3, and corresponding taper flanging die head 3 is provided with a positioning fixture 4; The port of positioning fixture 4 is concave cone faces 5, and the concave cone face 5 of the taper of taper flanging die head 3 and positioning fixture 4 ports cooperates.

The angle of the concave cone face 5 of the taper of taper flanging die head 3 and positioning fixture 4 ports is 70 ° ~ 90 °.

During use pipe fitting 6 being put into positioning fixture 4 compresses; Starting pressure machine 7 makes nut sleeve 1 drive self-centering 2 and moves ahead; Taper flanging die head 3 is aimed at pipe fitting 6 self-centering flange, utilizes 5 self-centerings of concave cone face, automatic capturing, the automatic purpose that reaches turned welt of regulating. and turned welt is even. and good to neutrality. simple in structure. expense is lower.
