Abstract
The invention discloses a thin-plate straight reelpipe welding method and device, which can effectively avoid the influence of springback of materials to welding formation and improve the forming accuracy of parts. The core of the device is a core rod for welding and positioning, the core rod is similar to be cylindrical, and a positioning groove, a welding avoidance groove and tangential sections are formed in the length direction of the core rod. When the device is operated, end sockets of the parts are bent to form small bent sides and are inserted into a positioning notch of the core rod, calipers are utilized to clamp and fix the parts on the core rod, and the tangential sections of the two sides of the core rod can play a role in space compensation.
Description
Technical field
The application relates to a kind of welding forming technology of tubing, specifically a kind of Thin-plate straight reelpipe welding method and device, is particularly useful for thin plate high strength, shaping that high resilient material (as high strength steel, titanium alloy etc.) welds straight pipe crimping.
Background technology
At present, the straight pipe crimping of welding of common materials is by the curling shaping of three beaming roller beds, during shaping, woollen is by the upwards support force of two side shafts and central shaft downward pressure, and side shaft rotarily drives woollen and advances that its inboard locations pressurized is produced is bending simultaneously, welds opposite joint after shaping.But due to high strength steel, when titanium alloy etc materials is shaped, resilience is large, is almost also in flat condition after the curling shaping of three beaming roller beds; Traditional manufacturing process cannot meet high strength, high resilient material is shaped.
Summary of the invention
High strength cannot be met in order to solve conventional method, the straight pipe crimping of high resilient material is shaped, and the object of the present invention is to provide a kind of Thin-plate straight reelpipe welding method and device, can effectively avoid material rebounds on the impact of welding forming, improves part forming precision.
Thin-plate straight reelpipe welding method, is characterized in that comprising following steps:
1) the little crimp of about 90 degree is first processed respectively at the center, both sides of sheet material to be processed;
2) also have a columniform welding plug of class, the length direction of this plug is provided with locating slot and groove and tangential section are hidden in welding;
3) inserted in locating slot by the little crimp of sheet material described in step 1), the outside clamp then sheet material being rolled in plug are located,
4) implement welding at the groove place of hiding of plug, sheet material is formed and directly rolls up tubular member;
5) the part wall extruded outside plug tangential section takes out the tubular member welded.
Thin-plate straight reelpipe welder, containing support and the plug for welding location, 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, the both ends of the surface of plug are hinged with the connector of hinge shape respectively, and this connector can be fixed on rack body.
Technique scheme supports plug with support, and plug all outputs notch up and down; One of them notch is locating slot, for retaining element relative to plug position, deflects when preventing part stress from bending; Hide when another notch is and hides groove for welding opposite joint.During operation, part tip bend gone out little crimp and insert plug locating notch, then with clamp, part being fixed clampingly on plug; After welding, clamp are unclamped taking-up part.Because plug both sides are effects that tangential section can play space compensation, prevent the distortion of welding long tube generation large scale.The high resilience taking out material after part can become regular pipe by the tension force produced radially, and the larger material of resilience is more easily processed, and reach and both solve conventional methods Form springback problem, solution welding deformation affects precision problem again.
The beneficial effect of the application is: change the resilience that material conventional method is processed in shaping best factor, material rebounds is larger, and after having welded, tension force is radially larger, and the pipe part after shaping is more regular.The product that the apparatus structure adopted is simple, operation is very easy, the plug of handling ease, replacing different size and clamp just can process different size, highly versatile.Further illustrate originally novel below in conjunction with drawings and Examples.

Detailed description of the invention
See accompanying drawing, for sheet part 1 to be processed before welding, in the middle part of its dual-side, first process the little crimp 2 for locating, little crimp 2 is about 90 degree relative to plate material parts body angle of bend.Plug 3 is cylinders that there is tangential section 6 both sides, length direction along plug is respectively equipped with locating notch 4 and notch 5 is hidden in welding, the tangential section 6 that notch 5 and both sides are hidden in locating notch 4 and welding preferably distributes alternately around plug 2, support 8 is for supporting and stationary core rod 2, also be provided with the hinged connector 7 of hinge in the two ends of plug 2, this connector 7 can be fixed with the alignment pin 9 on support.During use, the little crimp of sheet part 1 is plugged in the locating notch 4 of plug 3, as shown in Figure 1, bending plate part 1 in the direction of the arrow, make sheet part 1 and plug 2 fit as far as possible, then sheet part 1 is wound around with thin wire, to its objective is when preventing clamping sheet part 1 relatively welding hide notch 5 large-size deflection impact welding occur, with clamp 10 and fixture 11, sheet part 1 is fixed on plug again, notch 5 place is hidden in the welding making the welding edge at sheet part 1 two ends just be positioned at plug, completes the location of the front sheet part 1 of welding.Locate and complete sheet part 1 and plug 2 to be revolved on the support 8 that turnback is put into as shown in the figure along axle.Again the connector 7 at plug two ends is snapped onto the two ends of support alignment pin 9, plug 2 is made to be fixed on support 8, welding along plug is hidden notch 5 and is implemented welding job, sheet part 1 forms a uniform weld seam 12, sheet part 1 is welded into a tubular member; Finally exactly sheet part 1 is taken off from plug 2, first the connector 7 at plug two ends is departed from the two ends of support alignment pin 9, in two both sides, tangential section 6 position of plug 2, certain pressure is applied to sheet part 1, chord length due to plug tangential section 6 is less than tangential arc length, the surface of plug 2 can not be close to after making the stressed generation slight deformation of sheet part 1, can easily sheet part 1 be taken out.
