Abstract
The utility model provides a sheet straight reelpipe welding device. The sheet straight reelpipe welding device can effectively avoid influence of material springback on welding forming, and improves forming precision of parts. The core of the sheet straight reelpipe welding device is a mandrel which is used for welding positioning, the mandrel is similarly cylindrical, a positioning groove and a welding avoiding groove are formed in the mandrel in the length direction, and tangential sections are arranged on the mandrel in the length direction. When operation is carried out, the end of a part is bent to form a small bent edge, and is inserted into an opening of the positioning groove of the mandrel, the part is tightly clamped and is fixed on the mandrel through a pair of calipers, and the tangential sections on the two sides of the mandrel can play a role in space compensation.
Description
Technical field
The application relates to a kind of welding forming technology of tubing, and specifically the straight pipe crimping welding method of a kind of thin plate and device are particularly useful for the shaping of thin plate high strength, the straight pipe crimping of high resilient material (such as high strength steel, titanium alloy etc.) welding.
Background technology
At present, the straight pipe crimping of the welding of common materials is by the curling shaping of three beaming roller beds, woolen cloth is subjected to upwards support force and the central shaft downward pressure of two side shafts during shaping, simultaneously side shaft rotarily drive woolen cloth advance make its inboard everywhere pressurized produce crooked, welding opposite joint after being shaped.But because high strength steel, when titanium alloy etc materials is shaped resilience large, almost also be in dull and stereotyped state after the curling shaping of three beaming roller beds; Traditional manufacturing process can't satisfy high strength, high resilient material is shaped.
Summary of the invention
Can't satisfy high strength, the straight pipe crimping shaping of high resilient material in order to solve conventional method, the object of the present invention is to provide the straight pipe crimping welder of a kind of thin plate, can effectively avoid the material resilience on the impact of welding forming, improve the part forming precision.
The straight pipe crimping welder of thin plate, contain support and be used for the plug that welding is located, it is characterized in that described plug is that a class is cylindrical, the length direction of this plug is provided with locating slot and groove and tangential section are hidden in welding, be hinged with respectively the connector of hinge shape on the both ends of the surface of plug, this connector can be fixed on the rack body.
Technique scheme is to use the stent support plug, and plug is all left up and down notch; One of them notch is locating slot, is used for retaining element with respect to the plug position, prevents from deflecting when part stress is crooked; Another notch is to hide when groove is used for the welding opposite joint to hide.During operation the part tip bend gone out little crimp and insert the plug locating notch, then with clamp part is fixed clampingly on the plug; Weld and clamp are unclamped the taking-up part after complete.Because the plug both sides are effects that tangential section can play space compensation, prevent from welding the distortion of long tube generation large scale.Take out the tension force that the high resilience of material can produce radially behind the part and make it become regular pipe, and the larger material of resilience more easily processes, reach and both solve conventional way Form springback problem, solving again welding deformation affects precision problem.
The application's beneficial effect is: change the resilience of material conventional method processing in the shaping best factor, the material resilience is larger, and radially tension force was larger after welding was finished, and the pipe part after the shaping is more regular.The apparatus structure that adopts is simple, operation is very easy, handling ease, the plug of replacing different size and the product that clamp just can be processed different size, highly versatile.Below in conjunction with drawings and Examples to this novel further specifying.

Number description: notch, 6 tangential sections, 7 connectors, 8 supports, 9 alignment pins, 10 clamp, 11 fixtures, 12 weld seams are hidden in 1 sheet part, 2 little crimps, 3 plugs, 4 locating notches, 5 welding
The specific embodiment
Referring to accompanying drawing, before welding, at first process the little crimp 2 for the location for sheet part to be processed 1 at its dual-side middle part, little crimp 2 is about 90 degree with respect to plate material parts body angle of bend.Plug 3 is cylinders that there is tangential section 6 both sides, be respectively equipped with locating notch 4 and notch 5 is hidden in welding along the length direction of plug, the tangential section 6 that notch 5 and both sides are hidden in locating notch 4 and welding preferably distributes alternately around plug 3, support 8 is used for supporting and stationary core rod 3, also be provided with the hinged connector 7 of hinge in the two ends of plug 3, this connector 7 can with support on alignment pin 9 fixing.During use, the little crimp of sheet part 1 is plugged in the locating notch 4 of plug 3, as shown in Figure 1, along direction of arrow bending plate part 1, sheet part 1 and plug 3 are fitted, then twine sheet part 1 with thin wire, its objective is that notch 5 generation large-size deflections impact welding are hidden in sheet part 1 relative welding when preventing from clamping, with clamp 10 and fixture 11 sheet part 1 is fixed on the plug again, notch 5 places are hidden in the welding that makes the welding edge at sheet part 1 two ends just be positioned at plug, finish the location of sheet part 1 before the welding.Locate complete sheet part 1 and plug 3 are put into as shown in the figure support 8 along axle Rotate 180 degree on.Again the connector 7 at plug two ends is snapped onto the two ends of support alignment pin 9, plug 3 is fixed on the support 8, hide notch 5 along the welding of plug and implement welding job, form a uniform weld seam 12 at sheet part 1, sheet part 1 is welded into a tubular member; Exactly sheet part 1 is taken off from plug 3 at last, at first the connector 7 at plug two ends and the two ends of support alignment pin 9 are broken away from, both sides, two tangential sections, 6 position at plug 3 apply certain pressure to sheet part 1, because the chord length of plug tangential section 6 is less than tangential arc length, make the surface that can not be close to plug 3 after the sheet part 1 stressed generation slight deformation, can easily sheet part 1 be taken out.
