Abstract

The utility model relates to a steel tube shaping and welding machine, which belongs to mechanism shaping equipment technical field, for solving the problem on current steel tube shaping and welding machine which is bad on the quality, low efficiency and high on the cost. The utility model comprises a frame, a roll stand and shaping rolls. The shaping rolls are four shaping rolls with circular arc concave revolution surface, which are positioned on a U-type roll stand separately. The frame is rectangle, and rectangle through holes for roll stand installation and orientation are arranged on the two vertical rims of the frame. The four shaping rolls are positioned alone the inside four sides as two rolls opposite with each other, and the shaping rolls stand is arranged between upper shaping roll and bottom roll. The corresponding circular arc bus of the four shaping rolls make up a circular, and two adjustment orientation devices are positioned on the upper roll stand and side roll stand separately, which can make the rough shaped steel tube through the shaping and welding machine achieve perfect shape in order to directly enter the welding line production, without previous expanding working procedure. The utility model has the advantages of saving time and workload, high efficiency, good quality on the produced steel tube and low production cost.

Description

The steel pipe linking machine

Technical field

The utility model relates to a kind of steel pipe linking machine, belongs to mechanical modular system technical field.

Background technology

In steel pipe industry manufacturing industry, during production, the blank of preliminary compression moulding further need be finalized the design by means of the steel pipe linking machine, for following one welding sequence prepared with steel plate compression moulding.Comprise framework, roller frame and cylinder setting roll in its formation of traditional steel pipe linking machine, setting roll is generally about seven, constitutes regular polygon, and vertical shaping steel tube blank through regular polygon is further finalized the design.Be bordering on polygon through its cross section of blank after finalizing the design like this, inconvenience enters into the welding sequence welding, also needs further finalize the design to blank by means of expanding machine, just can enter into down one welding sequence and carry out the weld seam operation.Adopt the said equipment and technology to make steel pipe, of poor quality, work efficiency is low, the cost of manufacture height.

Summary of the invention

The utility model purpose provides a kind of hole enlargement operation, steel pipe linking machine that the joint close work efficiency is high of saving, and improves the joint close pipe quality.

It is as follows to address the above problem the technical scheme that is adopted:

A kind of steel pipe linking machine, it comprises framework, roller frame and setting roll, said setting roll is 4 setting rolls with circular arc revolution concave curved surface, 4 setting rolls respectively are installed on " U " shape roller frame, framework is a rectangle, two stile frames of framework 6 are provided with the penetrating rectangular opening that the location is installed for the roller frame, 4 setting rolls in framework 6 along four limits positioned opposite in twos, and the roller frame 11 of being located at the setting roll 12 of both sides places between the roller frame 7 of setting roll 8 up and down, 4 relative arc generatrixs of setting roll constitute a circle, and top roll frame 7 and side roller frame 11 are equipped with the adjusting positioner.

Above-mentioned steel pipe linking machine, said adjusting positioner is that top roll frame 7 and both sides roller frame 11 are equipped with adjusting positioning screw 10, the adjusting positioning screw 10 of top roll frame 7 is threaded with the entablature of framework 6, the adjusting positioning screw 10 of side roller frame 11 is threaded with a location-plate 5, a lock-screw 2, nut 1 are respectively established in location-plate 5 two ends, and the head of screw 2 places in the slideway set on the framework 63.

Above-mentioned steel pipe linking machine, said top roll frame 7 two ends and 11 on both sides roller frame are provided with pressure buffer regulating spring 4.

Above-mentioned steel pipe linking machine, the institute setting roll of saying 8 middle parts are fixed with circular guide and limit plate 9 along circumference.

The utility model is the improvement on existing steel pipe linking machine basis, adopt four setting rolls to replace existing cylinder setting roll with circular arc revolution concave curved surface, and four relative arc generatrixs of setting roll constitute a circle, can make steel pipe moulded blank obtain desirable typing effect like this through this linking machine, carry out the weld seam operation thereby can directly enter into welding sequence, save former hole enlargement operation.Therefore, use the utility model carry out the steel pipe joint close save time, laborsaving, the effect height, the tube quality of processing and fabricating is good, cost of manufacture is low, the utility model is to be the crucial corollary equipment that blank is made steel pipe with the steel plate.

Description of drawings

Fig. 1 is that structural representation cuts open in the master office of looking of a kind of embodiment of the utility model;

Fig. 2 is the left view of Fig. 1;

The parts label is respectively in the accompanying drawing: 1-nut, 2-lock-screw, 3-slideway, 4-pressure buffer regulating spring, 5-location-plate, 6-rectangular frame, 7-upper and lower roll frame, the upper and lower setting roll of 8-, 9-guide and limit plate, 10-regulate positioning screw, 11-side roller frame, 12-side setting roll.

The specific embodiment

Below in conjunction with the embodiment accompanying drawing, the utility model is described in further detail:

Consult accompanying drawing.The steel pipe linking machine that illustrated embodiment provides is the corollary equipment of straight welded pipe production line.During use, be installed in after the steel pipe forming hydraulic press of production line, preferably select for use four to be one group, series connection at interval, about 1 meter of spacing distance is progressively finalized the design by joint close so that make through the shaping steel tube blank of this machine.For preventing that in the joint close process blank displacement that rotates influences the joint close quality, can the welding of setting roll 8 middle parts fix a circular guide and limit plate 9 on preceding two steel pipe linking machines.In process, the abutment joint that makes steel tube blank up, and it is mobile to go ahead, and so also is convenient to the operator and observes the joint close situation, so that the joint close unit is transferred to optimum Working.

Consult Fig. 1,2.When need were adjusted spacing between four setting rolls, the adjusting positioning screw 10 of the adjusting positioning screw 10 that can be by adjusting the roller frame 7 of going up setting roll 8 and the roller frame 11 of both sides setting roll 12 was realized, makes setting roll be in desirable operating position.

Before adjusting two side setting rolls 12, at first location-plate 5 is fixed on the upper and lower slideway 3 with screw 2, nut 1, and then adjusting screw(rod) 10, make screw rod 10 promote side roller 11 and produce relative motion, thereby reach the purpose that is adjusted to the forming roll spacing with framework 6.

For guaranteeing that unit is safe and reliable and the steel tube blank displacement is steady, can set up pressure buffer regulating spring 4 at top roll frame 7 two ends and two 11 on side roller framves.Spring 4 can adopt cylindroid helical-coil compression spring.
