Abstract
The utility model relates to a pipe socket welding clamping device belonging to the mechanical field. The pipe socket welding clamping device provided by the utility model comprises a strip-shaped strake, wherein a limiting hole is formed in each of the two ends of the strake, the strake parts with the limiting holes keep flat, the middle part of the strake is bent to be circular, a screw passes through the limiting holes, one end of the screw is fixed on a base, and a nut is mounted at the other end of the screw. By adopting the clamping device provided by the utility model, the pipe and a flange root can be tightly pressed together to facilitate welding.
Description
Technical field
The utility model relates to a kind of tubing socket weld clamping device, belongs to mechanical field.
Background technology
PE tubing connects and belongs to mechanical connection, need take the mode of socket weld that tubing and flange root are coupled together, owing to inevitably have the gap between tubing and the flange root, tubing and flange root can produce and relatively move to its contact-making surface welding the time, the weld seam of cooling can be owing to the crack appears in relatively moving of tubing and flange root fully, even like this flange root finished of welding since the existence in crack also be easy to come off, influence product quality, even the personal safety that jeopardizes operating personnel, though the present closed-entry snap joint that has can step up flange root and tubing together, but cost is higher, and because the difference of closed-entry snap joint shrinkage factor easily causes the joint infiltration when temperature difference is big, the phenomenon that comes off.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the tubing socket weld that a kind of cost is low, quality is light clamping device is provided, tubing and flange root closely can be forced together, convenient welding.
Tubing socket weld clamping device described in the utility model comprises the hoop bar of strip, and spacing hole is established at hoop bar two ends respectively, the hoop bar that is provided with spacing hole partly keeps straight, and the intermediate portion bending is round shape, and screw rod passes spacing hole, screw rod one end is fixed on the base, and the other end is installed nut.
Operation principle and process:
After tubing inserted flange, tubing socket weld clamping device described in the utility model is enclosed within on the flange root, fastening nut, make the circular, hoop bar tightly wale the flange root, continue fastening nut, make flange root inner surface fully contact with pipe outer surface, exert pressure and make the molecule at flange root inner surface and pipe outer surface two interfaces tangle fully and combine together, after the enough time of pressurize, unclamp screw rod and remove clamping device, the deformation of flange root and tubing can not return to original shape, makes that two parts can not relatively move and influence welding quality when welding.
Establish fixing hole on the described base, fixing hole is convenient to fix tubing socket weld clamping device on the ground with screw rod.
Described hoop bar material is the 65Mn steel alloy, good springiness, and rebound velocity is fast.
The beneficial effect that the utility model compared with prior art has is:
Tubing socket weld clamping device described in the utility model, flange root inner surface is fully contacted with pipe outer surface, make the molecule at flange root inner surface and pipe outer surface two interfaces tangle fully and combine together, prevent from when welding, relatively moving, guarantee welding quality, prevented the generation of accident.
Description of drawings
Fig. 1 is the utility model embodiment schematic diagram.
Among the figure: 1, screw rod; 2, nut; 3, hoop bar; 4, spacing hole; 5, base; 6, fixing hole.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, tubing socket weld clamping device described in the utility model, the hoop bar 3 that comprises strip, spacing hole 4 is established at hoop bar 3 two ends respectively, and the hoop bar that is provided with spacing hole 4 partly keeps straight, the intermediate portion bending is round shape, screw rod 1 passes spacing hole 4, and screw rod 1 one ends are fixed on the base 5, and the other end is installed nut 2, establish fixing hole 6 on the described base 5, described hoop bar 3 materials are the 65Mn steel alloy.
After tubing inserted flange, tubing socket weld clamping device described in the utility model is enclosed within on the flange root, fastening nut 2, make circular, hoop bar 3 tightly wale the flange root, continue fastening nut 2, make flange root inner surface fully contact with pipe outer surface, exert pressure and make the molecule at flange root inner surface and pipe outer surface two interfaces tangle fully and combine together, after the enough time of pressurize, unclamp nut 2 and remove tubing socket weld clamping device, the deformation of flange root and tubing can not return to original shape, makes that two parts can not relatively move and influence welding quality when welding.
