Abstract

The utility model provides a punch forming die for a special-shaped connection pipe, and relates to a processing method of the special-shaped connection pipe in pressure vessel products. The punch forming die overcomes the shortcomings that a traditional processing method adopting a forging machine is high in cost and long in manufacturing cycle, and structurally comprises a connection pipe female die 1, a stripper plate 2, a locating plate 3, a limiting block 4 and a connection pipe male die 5. The section of one end of the connection pipe female die 1 and the section of one end of the connection pipe male die 5 are of half-round shapes, the section of the other end of the connection pipe female die 1 and the section of the other end of the connection pipe male die 5 are of square shapes or half-oval shapes, and the two ends are connected in a tapered mode. The locating plate 3 is arranged in the middle of the connection pipe female die 1, and the limiting block 4 is arranged at the square or half-oval end of the connection pipe male die. The connection pipe female die 1 and the connection pipe male die 5 are made of materials good in lubrication performance. According to the punch forming die, punch forming and die releasing of the special-shaped connection pipe can be guaranteed easily, operation is convenient, the die universality is good, the applicable size range is large, the cost is greatly lowered, the efficiency is improved, and all performance indexes meet the relevant standard requirement.

Description

The punch-forming mold that a kind of abnormity is taken over
Technical field
The utility model relates to the punch-forming mold that in pressure vessel product, a kind of abnormity is taken over.
Background technology
At present, in equipment in Oil Refining, Coal Chemical Industry equipment and other pressure vessel, take over and connect two difform parts through conventional abnormity.Conventionally the thickness of pipe wall that abnormity is taken over, its structure one end section is circular, other end cross section is quadrangle or ellipse, taper connection between two ends, the processing method that tradition abnormity is taken over adopts the mach method of forging, to equipment require high, forging cost is high simultaneously, and the manufacturing cycle is long.
Summary of the invention
The technical problem that the utility model solves is to overcome the shortcoming that above-mentioned abnormity is taken over traditional diamond-making technique, raises the efficiency, and reduces costs.
The press forming die that the utility model provides a kind of abnormity to take over, comprising: take over die 1, stripper 2, location-plate 3, limited block 4, take over punch 5; Described adapter die 1, an end section of taking over punch 5 is semicircle, other end cross section is square or semiellipse type, taper connection between two ends; Described location-plate 3 is being taken over the middle part of die 1, and described limited block 4 is being taken over square or semiellipse type one end of punch.Adapter die 1, adapter punch 5 are selected the good material of self lubricity.
A key problem in technology difficult problem of the present utility model is to solve in the non-round surface bullet drop stamping of heavy wall sheet-metal press working, its structure is that an end section is circular, other end cross section is the sheet forming problem that quadrangle or oval-shaped abnormity are taken over, and in the time taking over punch, adapter Die Design, must consider the cooled amount of contraction of hot pressing workpieces; Location-plate will ensure that location rapidly, accurately on mould; Take over die 1 for this reason, to take over punch 5 material requirements self lubricities better.
The utility model compared with prior art has the following advantages:
1, be easy to ensure the hot press-formed and demoulding of abnormity adapter, easy to operate.
2, described adapter die, takes over punch and selects the material that self lubricity is good, and die profile and size can one-time-reach-places, and without carrying out machined moulding, mould highly versatile, greatly reduces cost, has improved efficiency again.
3, adopt the limb of the thick wall special-shaped adapter of this Mould Machining, the property indices such as apparent size, form and position tolerance, mechanical performance and physics and chemistry test all reach relevant criterion requirement.
4, this mould suitable dimensions scope is larger, height of nozzle≤1500mm, 10mm≤wall thickness≤60mm.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, the forming die structure that abnormity is taken over comprises: take over die 1, stripper 2, location-plate 3, limited block 4, take over punch 5; Described adapter die 1, an end section of taking over punch 5 is semicircle, other end cross section is square or semiellipse type, taper connection between two ends; Described location-plate 3 is being taken over the middle part of die 1, and described limited block 4 is being taken over square or semiellipse type one end of punch.Adapter die 1, adapter punch 5 are selected the good material of self lubricity.
When use, adapter punch 5 is arranged on forcing press central authorities slide block; Abnormity is taken over point symmetrical two lobe blankings, and every lobe is placed in respectively to be taken in die 1, and location-plate 3 is controlled the position that blank is placed, and takes over die 1 and is connected with press bench, takes over die 1 play while preventing work; Move downward by press equipment, take over punch 5 and slip into adapter die 1, limited block 4 is definite slips into position, completes the heat stamping and shaping of thick wall special-shaped adapter; Press equipment moves upward, and drives adapter punch 5 to move upward to depart from and takes over die 1, utilizes stripper 2 to complete the demoulding work that abnormity is taken over.
