Description
Technical field
The present invention relates to a kind of pipe fitting pressure die and processing method thereof, belong to Machining Technology field.
Background technology
In modern industry, bend pipe fitting application widely, bending die and pressure die make pipe fitting brake forming.Pressure die normally makes elbow curvature shaping with the cooperation such as bending die, guiding module.If but at work installation mold time do not note, there is dislocation in bending die and pressure die profile, bend pipe circular arc also will become flat affects elbow curvature effect.Thus how pressure die ensures that the profile of upper and lower mould does not coaxially misplace and is and important.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of pipe fitting pressure die and processing method thereof, and this pipe fitting pressure die structure is simple, and technique is simple, and can be reached the required precision of drawing by this method, ensure that precision when pipe fitting bends after fastening.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of pipe fitting pressure die, comprise upper die and lower die, upper die and lower die are respectively equipped with plate face, vertical compression clamp is provided with below horizontally disposed plate face, the middle part compressing clamp is provided with semicircle pass compact type face, and the compression profile of upper die and lower die fastens the overall circle of rear formation one; Be provided with location-plate in the end in cope match-plate pattern face, location-plate is provided with locating hole; In the middle part of the end face in lower bolster face, be provided with positioning strip, positioning strip is also provided with locating hole, the locating hole on this locating hole and patrix is on same vertical line.
To the processing method of pipe fitting pressure die, comprise the following steps:
1) upper die and lower die are carried out blanking depending on as a whole;
2) utilize planing, grinder and pincers worker to process plate face, compression clamp, location-plate and positioning strip profile, overall length direction increases 1mm, and leaves 0.4-0.5mm surplus;
3) borer carries out bore hole to the compression profile compressed on clamp, and two distance of center circle compressing profile are from being 1mm;
4) drill the locating hole on patrix location-plate and counterdie positioning strip respectively, the distance of locating hole is that actual range increases 1mm;
5) part entirety is heat-treated, blast and the PROCESS FOR TREATMENT of turning blue
6) cut-off rule of centering Linear cut, utilizes wire cutting machine to split upper and lower mould;
7) profile place, location is carried out to the chamfering of 1 × 45 °.
The application adopts said method, not only ensure that the profile of the compression profile of upper die and lower die is complete, and profile and axis all there will not be dislocation, this ensures that theres operationally to compress profile and engage compression pipe fitting smoothly.This processing method greatly reduces the difficulty of processing, ensure that the quality of pressing pipe fitting.

Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of pipe fitting pressure die, comprise upper die and lower die, upper die and lower die are respectively equipped with plate face 1, vertical compression clamp 2 is provided with below horizontally disposed plate face 1, the middle part compressing clamp 2 is provided with semicircle pass compact type face 3, and the compression profile 3 of upper die and lower die fastens the overall circle of rear formation one; Be provided with location-plate 4 in the end in cope match-plate pattern face 1, location-plate 4 is provided with locating hole; In the middle part of the end face in lower bolster face 1, be provided with positioning strip 5, positioning strip 5 is also provided with locating hole, the locating hole on this locating hole and patrix is on same vertical line.
To the processing method of pipe fitting pressure die, comprise the following steps:
1) upper die and lower die are carried out blanking depending on as a whole;
2) utilize planing, grinder and pincers worker to process plate face, compression clamp, location-plate and positioning strip profile, overall length direction increases 1mm, and leaves 0.4-0.5mm surplus;
3) as shown in Figure 4, borer carries out bore hole to the compression profile compressed on clamp, and two distance of center circle compressing profile are from being 1mm;
4) drill the locating hole on patrix location-plate and counterdie positioning strip respectively, the distance of locating hole is that actual range increases 1mm;
5) part entirety is heat-treated, blast and the PROCESS FOR TREATMENT of turning blue
6) cut-off rule of centering Linear cut, utilizes wire cutting machine to split upper and lower mould;
7) profile place, location is carried out to the chamfering of 1 × 45 °.
