Description

Technical Field

[0001] The utility model relates to the technical field of metal material welding, in particular to an internal support welding device for porous metal materials. Background Art

[0002] Metal porous materials are metal materials with a large number of directional or random holes dispersed inside. Due to different design requirements for holes, the holes in metal porous materials can be foam-shaped, lotus-shaped, honeycomb-shaped, etc. Metal porous materials can also be divided into independent hole type and continuous hole type according to the shape of their holes; among them, independent type materials have the characteristics of small specific gravity, good rigidity, specific strength, shock absorption, and sound absorption; in addition to the above characteristics, continuous type materials also have the characteristics of good permeability and air permeability. Because metal porous materials have the characteristics of structural materials and functional materials, they are widely used in aerospace, transportation, construction engineering, mechanical engineering, electrochemical engineering, environmental protection engineering and other fields.

[0003] At present, the traditional welding method for metal materials is external pressure. However, when using external pressure welding to weld metal porous materials, there will be scratches on the surface of the metal porous material during the process of extrusion and shaping of the metal porous material by the external mold. Surface scratches will cause uneven permeability of the metal porous material, thereby affecting product performance.

[0004] In the process of rolling and welding metal pipes with porous metal materials, the rolled materials cannot be perfectly round, which will lead to uneven welds during welding and make it impossible to directly perform straight seam welding. In addition, porous metal materials require a lot of heat dissipation during welding. If the heat dissipation is not good, the high temperature will easily cause the holes near the weld to melt and collapse, resulting in leakage points in the material that exceed the hole accuracy of the material.

[0036] The embodiment of the utility model provides an internally supported welding device for porous metal materials. The device performs straight seam welding of porous metal materials in an internally supported manner, which can not only avoid surface scratches of the porous metal materials during welding, but also solve the heat dissipation problem during the welding process.

[0037] like Figures 1 to 4 As shown, the metal porous material internal support welding device provided in the embodiment of the present invention includes: a support frame, a central axis, a three-petal split outer mold, a slide rail, a weld clamping module, a welding module and a circulating cooling module.

[0038] The central axis is vertically fixed on one side of the supporting frame.

[0039] In this embodiment, the support frame is a columnar body placed directly on the ground, and the central axis is a cylinder parallel to the ground and vertically fixed to one side of the support frame.

[0040] The three-petal split outer mold is coaxially sleeved on the outside of the central axis and is used to support the material sleeved on the outside of the three-petal split outer mold into a cylindrical shape.

[0041] The material is rolled from a metal porous material plate, and has a weld to be welded.

[0042] In this embodiment, the material is a cylindrical structure made of a metal porous material plate, and two side surfaces of the metal porous material plate that are close to each other need to be welded together.

[0043] The three-petal split outer mold is coaxially fixedly sleeved on the outside of the central axis. The three-petal split outer mold is supported into a circle by a three-petal mold lifting device arranged inside the three-petal split outer mold, thereby supporting the material sleeved outside the three-petal split outer mold to deform into a circle.

[0044] The slide rails are parallelly erected above the central axis, and the weld pressing module and the welding module are both slidably arranged on the slide rails.

[0045] In this embodiment, the slide rail can be directly fixed on the top of the support frame, and the slide rail can also be fixed above the central axis through other bases.

[0046] The weld pressing module faces the weld of the material and is used to press the weld during sliding along the slide rail.

[0047] In this embodiment, before controlling the three-petal split outer mold to round the material, it is necessary to adjust the position of the weld of the material so that the weld is directly opposite the weld pressing module and the welding module.

[0048] The welding module is used to perform straight seam welding on the weld after the weld is compressed.

[0049] Specifically, the direction and speed in which the weld pressing module and the welding module slide along the slide rail can be manually controlled by a worker, or automatically controlled by a driving motor.

[0050] The circulating cooling module is communicated with the three-petal split outer mold and is used for introducing cooling liquid into the interior of the three-petal split outer mold for circulating cooling.

[0051] In this embodiment, the coolant may be water.

[0052] Furthermore, the weld pressing module includes a pressing cylinder and a pressing roller.

[0054] The clamping roller is fixed on the piston end of the clamping cylinder, and the clamping roller rolls along the length direction of the weld.

[0055] In this embodiment, the ventilation controls the piston end of the clamping cylinder to extend, so that the bottom end of the clamping roller is close to the weld. At the same time, the clamping cylinder is controlled to drive the clamping roller to move from left to right to press the material in a rounded state, thereby realizing the clamping roller to level the weld during the straight seam welding process of the porous metal material.

[0056] Furthermore, it also includes a first motor drive mechanism, which is used to drive the clamping cylinder to reciprocate along the slide rail.

[0057] That is to say, in the embodiment of the present invention, the movement of the weld pressing module on the slide rail is automatically controlled by the motor drive mechanism.

[0058] Furthermore, the welding module is a laser welding gun slidably arranged on a slide rail;

[0059] The output end of the laser welding gun is arranged toward the central axis.

[0060] In the embodiment of the present invention, after the weld pressing module presses the weld, the laser welding gun is controlled to move in the same direction behind the weld pressing module, thereby realizing laser welding of the weld.

[0061] Furthermore, it also includes a second motor drive mechanism, which is used to drive the laser welding gun to reciprocate along the slide rail.

[0062] That is to say, in the embodiment of the present invention, the movement of the laser welding gun on the slide rail is automatically controlled by the motor drive mechanism.

[0063] Furthermore, the circulating cooling module includes a liquid inlet, a liquid outlet, a circulating pump, a liquid supply pipe and a liquid supply tank.

[0064] The liquid inlet and the liquid outlet are both connected and arranged on the three-petal split outer mold.

[0065] The liquid inlet, the liquid outlet and the liquid supply box are all connected with the circulation pump through the liquid supply pipe.

[0066] The supply tank is used to store coolant.

[0067] In this embodiment, during the welding process of the welding module, the circulation pump is turned on to transport the coolant in the liquid supply tank into the three-petal split outer mold through the liquid inlet for circulation cooling, and then the coolant is injected back into the liquid supply tank through the liquid outlet to form a cooling cycle.

[0068] Furthermore, it also includes a slide rail base, and the slide rail is mounted on the slide rail base.

[0069] In this embodiment, the slide rail is fixed above the central axis through a slide rail base, and the slide rail base is used to keep the slide rail in the same horizontal plane.

[0070] Furthermore, the slide rail base is a telescopic slide rail base with adjustable height.

[0071] When the metal porous material internal support welding device provided by the embodiment of the utility model is actually used, a cylindrical material rolled from a metal porous material plate is sleeved on the outside of a three-petal split outer mold, and the material sleeved on the outside is supported and rounded by the three-petal split outer mold so that the weld of the material faces upward; then the weld pressing module is controlled to slide along the slide rail to press the weld flat; finally, the welding module is controlled to slide along the slide rail to perform straight seam welding on the pressed flat weld; at the same time, in the process of the welding module welding the weld, a circulating cooling module is used to introduce coolant into the three-petal split outer mold.

[0072] The utility model uses an inner support method to perform straight seam welding of porous metal materials, which can not only avoid surface scratches of porous metal materials during welding, but also solve the heat dissipation problem during welding. The utility model also greatly improves the production efficiency of materials and improves the consistency of products.
