Technical field
The invention belongs to steel processing technique field, more particularly to a kind of punch forming of steel pipe.
Background technology
Steel pipe is widely used in various structural steelworks as structural member, and the manufacture to steel pipe at present has a variety of sides
Formula, such as cast, turning shaping etc., but mostly shaping efficiency is relatively low, for the existing cold-rolling process of cold tube rolling and equipment matter
Measure uneven, and be molded fast, the good equipment of Forming Quality often involves great expense, complicated, it is difficult to promotes the use of.
The content of the invention
It is an object of the invention to provide a kind of special press machine, and the Special punching press-molding is efficient, Forming Quality is good,
Simple and ingenious structure, beneficial to promoting the use of.
Technical scheme is as follows：
A kind of special press machine, including base, the center of the base is equipped with a stepped groove along its vertical direction, described
Stepped groove is included the first groove, the second groove and the 3rd groove of isosceles trapezoid shape by its opening direction successively towards its slot bottom, the
Upward, small end connects the big end of one groove with the second groove；
Two die blocks not connected each other, the lower left corner of left die block are symmetrically equipped with first groove
It is respectively hinged at the lower right corner of right die block on the relevant position of the first groove front and rear sides wall, so that two die blocks can be with
Certain angle is freely rotated in the first groove；Two die blocks are each towards the side lower edge of the corresponding Yao Bi sides of the first groove
Equipped with the first rounded corner, the upper end-face edge of arc gap and the side is offered in the middle part of the side of Yao Bi sides equipped with oblique
Angle, arc transition is connected between the bevelling and the arc gap；Two die blocks are fixed in the first groove both sides waist respectively
The first spring in wall is pulled to fit with corresponding waist wall, so that the gap formed between side where the bevelling of two die blocks
Be enough to accommodate rolled steel pipe vertically through；
Backing plate is flatly equipped with second groove, the slot bottom of the 3rd groove and the bottom of second spring are fixedly linked,
The top of second spring is connected with stretching into the mandril of the 3rd groove slot bottom, and second spring is not exclusively sliding in natural length lower push rod
Go out the 3rd groove, so that in a non-operative state, mandril is passed through two die block tops after the backing plate to each recessed with first
The position that the corresponding waist wall of groove fits, and in the operating condition, the bottom face of two die blocks is gone on the backing plate top surface
When, two arc gaps are combined into a circular die cavity.
Further, first spring horizontal is set.
Further, the minimum level gap between two die block is located at the position below two arc gaps, and most
Small horizontal clearance is 3 with the circular die cavity diameter ratio:20.
Further, the angle between two waist walls of first groove is formed with face where the bevelling of two die blocks
The ratio between angle be 3:10.
Further, first groove and the second groove joint rounded corner are handled, and the second rounded corner poured out
The center of circle be located at two die blocks and the first groove front-rear side walls it is hinged when articulated shaft axis on, first falls described in rotation process
Fillet can be with the second rounded corner phase inscribe.
Further, the left and right sides wall of the base is respectively equipped with semicircular indentations.
Beneficial effects of the present invention：In the use of the present invention, under original state, two pressuring templates are by corresponding first bullet
Spring is pulled to the position that patch is thought with the first groove waist wall, and the gap of upper end becomes larger between two pressuring templates, accommodates the suitable of core rod and plate
Profit enters, and when plate is continued punching press by core rod downwards, plate is progressively convexly curved and is all introduced between two pressuring templates
Die cavity, when being placed in backing plate upper surface in pressuring template lower face, the respective arc gap of two pressuring templates is combined into required steel
Pipe formation die chamber, core rod is by plate stamping into steel pipe type this moment, and then core rod is retracted upwards, and mandril is made in the reset of second spring
With it is lower auxiliary the first spring together by two pressuring templates push up and cause two pressuring template upper end openings opening, become larger, steel pipe and mould
Core leaves, the demoulding separates.It can be seen from the above that the special press machine is progressively molded, Forming Quality is stablized, automatic demoulding, shaping efficiency
It is higher, it is simple and compact for structure and ingenious, it is easily fabricated, be conducive to promote the use of.
