Abstract

The utility model discloses a universal seaming machine, which comprises a framework (1) and a plurality of groups of rollers (2). The universal seaming machine is characterized in that a right-above roller (3) of each group of rollers (2) is connected onto a lifting stand (4), a lifting device (5) is connected above the lifting stand (4), two symmetrical upper slide rails (6) are arranged on the lifting stand (4) on two sides of the right-above roller (3),a lateral upper roller (7) is movably connected onto the upper slide rail (6), two symmetrical lower slide rails (8) are arranged on two sides of the center of the bottom end of the framework (1), and a lateral lower roller (9) is movably connected onto the lower slide rails (8). A small slide rail (10) is arranged between the lower ends of the two lower slide rails (8), and two symmetrical small rollers (11) are movably connected onto the small slide rail (10). When in use of the universal seaming machine, positions of the lifting device above the lifting stand and positions of the rollers on the upper slide rails, the lower slide rails and the small slide rail can be adjusted according to the diameter of steel pipes, so that the steel pipes can be surrounded by the rollers. Accordingly, the steel pipes in different specifications can be seamed, replacement of the rollers is omitted, positioning at a bottom line is realized and equipment and investment can be reduced.

Description

Omnipotent linking machine

Technical field

The utility model belongs to a kind of steel pipe process equipment, and concrete is a kind of linking machine of steel pipe.

Background technology

At present, steel pipes with straight needs to carry out the joint close butt joint through linking machine in process.Existing steel pipe linking machine comprises: some groups of rolls, roller regulating device, what this roller regulating device adopted is oil cylinder, regulates the position of roll through stretching of oil cylinder, to adapt to the steel pipe of different tube diameters.In addition, existing linking machine is taked the steel pipe centralized positioning, and just all rolls all will be gathered to the centre by oil cylinder control, hold the steel pipe that needs joint close tightly.The deficiency of its existence is: when regulating different tube diameters, the lead length of stretching out by oil cylinder realizes, still; The lead overhang is big more; The intensity of frame is more little, and the power that can bear is also less, causes the steel pipe joint close that existing linking machine can only be thin to the wall thickness wall thickness.In addition, all rollers are gathered to the centre during owing to adjusting, cause the frame of Delivery tube also will regulate height thereupon, and this brings very burden to operation.

Summary of the invention

The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved linking machine is provided, and it is rational in infrastructure, and is easy to operate,

For reaching above-mentioned purpose; The utility model is taked following technical scheme: the utility model comprises: frame, some groups of rolls is characterized in that: roll is connected on the crane directly over each group roll, and the crane top is connected with lowering or hoisting gear; The both sides and the frame of crane are slidingly connected; Directly over be provided with two on the crane of roll both sides the two just be " eight " font to being much of slide rail, be connected with roll above the side on the last slide rail through the leading screw activity; Be provided with the glidepath of two symmetries in the bottom center both sides of frame, the two is down " eight " font, on glidepath, is connected with the side-lower roll through the leading screw activity.Between two glidepath lower ends, be provided with little slide rail, be connected with the little roll of two symmetries on the little slide rail through the leading screw activity.

The utility model is taked technique scheme; Has following beneficial effect: when the utility model uses,, regulate the lowering or hoisting gear of crane top and go up the leading screw on slide rail, glidepath, the little slide rail according to the diameter of steel pipe; Thereby confirm roll location, make it surround steel pipe.Like this, can carry out joint close, need not to change roll, and realize the bottom line location, can reduce many equipment and investment the steel pipe of different size.It is bigger that each roller designs, and can adjust separately, can guarantee the stressed unanimous on the whole of each roller; And the stressed line of force of each roller is all pointed to the center of circle of steel pipe; Integral body adopts seven roller envelopes one week, makes one week of steel pipe integral stressed relatively good, can satisfy requirement of strength.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:

Fig. 1 is the structure diagram of the utility model embodiment.

Mark among the figure: roll, 4-crane, 5-lowering or hoisting gear, the last slide rail of 6-, 7-side top roll, 8-glidepath, 9-side-lower roll, the little slide rail of 10-, the little roll of 11-, 12-prerotation vane directly over 1-frame, 2-roll, the 3-.

The specific embodiment

By shown in Figure 1, the utility model includes: frame 1, roll 2, and roll 2 has some groups, and each group collar is around a circumference.Directly over roll 3 be connected on the crane 4; Crane 4 tops are connected with lowering or hoisting gear 5; The both sides of crane 4 and frame 1 are slidingly connected; Directly over be provided with two on the crane 4 of roll 3 both sides the two just be " eight " font to being much of slide rail 6, be connected with roll 7 above the side on the last slide rail 6 through the leading screw activity; Be provided with the glidepath 8 of two symmetries in the bottom center both sides of frame 1, the two is down " eight " font, on glidepath 8, is connected with side-lower roll 9 through the leading screw activity; Between two glidepath 8 lower ends, be provided with little slide rail 10, be connected with the little roll 11 of two symmetries on the little slide rail 10 through the leading screw activity.

The utility model adopts multimachine frame memorial archway formula structure, just corresponding to one group of roll one memorial archway open frame is set, and has guaranteed the requirement of strength and the required precision of equipment; Seven groups of rollers in each frame, every group of roller all slides on track separately, can adjust separately; The intensity that operates steadily is big; Its intensity and stationarity are far longer than the guiding pole structure, and because of roller reasonable in design, generally can the joint close wall thickness greater than 20mm less than the thick steel pipe of 30mm.

The utility model is provided with prerotation vane 12 to roll directly over preceding two on Roller Design, make steel pipe in walking, can guarantee all the time to advance along center line.In steel pipe when inlet,, the crane of the first memorial archway frame is mentioned with lowering or hoisting gear-oil cylinder, treats depress oil cylinder after first frame of steel pipe entering, and its excess-three frame is adjusted by the model of steel pipe by elevator drives.
