Abstract
The utility model relates to a butt welding machine for a pipe external forming, which is characterized in that two detachable semicircular clamping plates of the butt welding machine are respectively fixed with three support plates which are respectively provided with a coining claw and a butt welding locating detent; the coining claw and the butt welding locating detent matched by nuts on a driving bolt and the support plate inward extends along the radial direction of the butt welding machine; between the driving bolt and the coining claw and the butt welding locating detent is a fastening type structure and is provided with balls. The utility model has the advantages of simple structure, convenient construction, which is portable and detachable, and the coating of the opening of the welded pipe can not be damaged because the coining claw and the butt welding locating detent just can do radial motion.
Description
The utility model is the shaping positioning fixture of pipeline counterpart welding, belongs to the welding specialty.
When pipeline welds in counterpart, the instrument of shaping fixed tube position need be arranged.In fact, existing diversified mouthpart is being used.No. 3952936 patents of the U.S. close " REFORMING PIPE CLAMP " (" rectifying pipe clamp " with the design, 1976), adopt two and half garden clevis plates, one side hinge, another side connects with the latch hinge, with the version of four folding formula shaping locating detents alive, can finish the function of shaping counterpart, and structure is comparatively simple.But one after the two clamping plates hinge connects, can not dismounting become two parts, uses and some inconvenience when transporting; Its two, when shaping was located, the shaping pawl rotatablely moved except that radial motion is arranged in addition.And rotatablely move, for majority the mouth of pipe of anticorrosive coat or other coatings being arranged, certainly will breakdown of coating to be fallen.So, coating layer workload be must increase, otherwise the performance and the life-span of pipe just influenced.
The utility model is exactly at the shaping that exists in the various bore pipe counterpart welding mouthpart to be used the problem of transporting inconvenience and damaging coating, designed a kind of new anchor clamps.
This shaping to mouthpart at above-mentioned deficiency, be designed to the hinge (5) between the two and half garden clamping plate (1) dismountable, and three gripper shoes (2) that are connected on each clamping plate, a shaping pawl (4) and a counterpart locating detent (10) respectively are set on gripper shoe, the shaping pawl is at the gripper shoe root, the counterpart locating detent is at the cantilever end of gripper shoe, and this two pawl is to be cooperated with screw on the gripper shoe by drive bolt (3), inwardly stretches along the footpath to mouthpart.Whole mouthpart is had six groups of shaping pawls and counterpart locating detent, be evenly distributed on the clamping plate.For stressed little in clamping plate hinge portion, the gripper shoe on the clamping plate is connected in the clamping plate center respectively and both sides are located for each 60 °.After the synthetic like this integral body, for every 60 ° of one group of pawls.Because the shaping pawl is stressed big, so be arranged on gripper shoe and the clamping plate place that is connected, the counterpart locating detent then is located at the cantilever end of gripper shoe.The mouthpart overall structure is seen for details Fig. 1.The counterpart locating detent is generally only made counterpart location usefulness, and is enough as gripper shoe intensity, but also the double as shaping is used.The cross section of clamping plate is a flute profile, in order to strengthen intensity, can add some stiffeners (6) at the clamping plate middle part.
The dismounting mode that two clamping plate connect hinge can be a pin plug formula, promptly hinge pin only one cap is arranged, and have chain to lead mutually, and the other end is tip (Fig. 2 (1)) with clamping plate; Also one of them hinge can be made hook-hang type, promptly bearing pin is fixed on the clamping plate, and the pan on another clamping plate is the half opening shape, with the hook bearing pin.Hinge openings hole (hook) can be single hook, also can be double hook.Single hook is the hook that weldering one steel plate curves in the clamping plate groove.Double hook be in clamping plate groove inboard or the outside each fix a sheet hook.These two kinds of structures see (2) and (3) among Fig. 2 for details.
The middle part of bolt is a screw thread.External end head in order to screw bolt with multiple instrument, is made the square toes of cross-perforating.Its inner end head is thinner slightly than threaded portion, and there is thin neck at the proximal head place, so that be connected with pawl, end face has hemisphere face shape ball nest.
The shaping pawl is identical with counterpart locating detent structure.It is the snap fastener that is connected at the outer middle part of a cambered surface, so that be connected with drive bolt.The structure of snap fastener is: the snap fastener profile is square or the garden body, in the garden cylindrical cavity is arranged, the accent internal diameter is identical with the bolt head external diameter, can hold bolt head and insert, be the conical surface at the bottom of the chamber, to hold ball.This kind structure is earlier packed ball into during assembling, places on the conical surface, and bolt head inserts, and hemisphere face is pressed on the ball, at last with mechanical means with accent close up (Fig. 1).In use, when pawl or ball have fault,, can be designed to detachable for ease of changing.One scheme is on above snap fastener cavity, and the cross-drilled hole of two symmetries is made a call at the thin neck of corresponding bolt place, and the hole pierces in the chamber, and each inserts one piece of pin (14) in the hole, passes from the thin neck of bolt, and bolt head is stuck in the snap fastener chamber, sees Fig. 3 (1) for details; Second kind of scheme is at above-mentioned cross-drilled hole place, processing twice translot, and penetrate cavity, in spring steel wire folder (15) card entry slot, equally also can make bolt head snap in (Fig. 3 (2)) in the snap fastener chamber.Just because of adopted this kind snap fastener formula combination between drive bolt and the pawl, and ball is arranged, so when shaping, because the rolling of ball, pawl moves without spin, so can protect the face coat of being joined two pipes together.
This kind anchor clamps can be designed to series of products according to the caliber size of butt joint pipe.Maximum ellipse garden degree that can shaping can design as required voluntarily, generally can reach about 5%.
In use, the two tubes of interface is to good, and suit is to mouthpart, pipe seam is in the middle of shaping pawl and the counterpart locating detent, tightens each counterpart locating detent and shaping pawl, and according to two pipe counterparts and distortion situation, adjust the shaping pawl, make two mouth of pipe complete matchings, can carry out weldering just.
This shaping is applicable to mouthpart and the counterpart welding of straight tube also is applicable to the counterpart welding of bend loss.
The utility model has the advantages that to the mouthpart easy accessibility each clamping plate weight of dismounting back is lighter, without lifting appliance, the transfer job site is very convenient during operation, and a people can move with a wet finger.Be applicable to the counterpart welding of straight tube and bend loss.Do not damage the coating of pipe when shaping, location, this brings certain benefit for the various cated pipes of welding.
