Technical Field

[0001] The invention relates to radiator welding equipment, in particular to a direct welding assembly device for a die-cast aluminum radiator. Background Art

[0002] A radiator refers to a device used for heating, which has a heat pipe and a heat sink. The heat sink is fixed on a heat plate to improve the heat dissipation efficiency. Radiators are widely used in various civil and public buildings such as residential, office, hotel, shopping mall, hospital, school, train carriages, mobile heating, simple mobile houses, etc.

[0003] A radiator generally includes a horizontal tube, a vertical tube and heat sinks arranged on the vertical tube. Currently, the horizontal tube and the vertical tube are generally arranged in an I-shape during manufacturing, and the heat sinks are located on the vertical tubes to form a radiator unit. The horizontal tubes of adjacent radiator units are generally connected in two ways. One is welding, and the other is fixed connection and communication with threaded connectors. The second method requires additional connectors to be manufactured, and the connectors may loosen and leak during use. Therefore, welding becomes the first choice, and there is no welding equipment for multiple radiator units on the market, so there is too much manual participation and low efficiency. In addition, since the heat sink spacing of the radiator unit is small, the traditional automatic welding device will be blocked and the horizontal tube of this type of radiator cannot be welded.

DETAILED DESCRIPTION

[0028] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0029] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0030] Example

[0031] This embodiment mainly describes the title of a die-cast aluminum radiator direct welding assembly device. The technical solution adopted by the present invention to solve the above technical problems is: a die-cast aluminum radiator direct welding assembly device, such as Figure 1-6 As shown, the radiator includes a plurality of radiator units 01, each radiator unit 01 has two transverse pipes 011 to be welded, which include:

[0032] Machine 10;

[0033] A supporting mechanism 20 , which is disposed on the machine platform 10 and is used to support the radiator unit 01 ;

[0034] The pressing mechanism 30 is arranged on the machine platform 10, and includes a front pressing device 301 and a rear pressing device 302 which are symmetrical in front and back, and each pressing device includes two pressing seats 303 which can slide relative to each other and are driven by a lifting cylinder to rise and fall simultaneously;

[0035] The heating and pushing mechanism 40 is arranged on the machine platform 10 and is located on the left side of the supporting mechanism 20. It includes a pushing device and two heating heads 401 arranged at the output end of the pushing device. The pushing device drives the two heating heads 401 to extend into the transverse tube 011 to heat the end of the transverse tube 011 so that the end of the transverse tube 011 expands due to the heat.

[0036] The abutment mechanism 50 is arranged on the machine 10 and is located on the opposite side of the pushing device. It is used to limit the position of the radiator unit 01 so that the heating head 401 squeezes the left transverse tube 011 and extends into the right transverse tube 011 that is heated and expanded. In this solution, the transverse tube 011 of the placed radiator unit 01 is expanded by heating, and the transverse tube 011 of the newly added radiator unit 01 is pressed into the expanded transverse tube 011. After cooling, an interference fit structure is formed between the two to form a seal. This solution does not require welding from the side, avoiding the problem of being blocked by the heat sink during welding, so that the efficiency and sealing effect are greatly improved; in addition, in order to further improve the sealing performance, an annular groove can be provided on the transverse tube 011 on the right side of each radiator unit 01, and a brazing material protruding out of the groove can be provided in the groove. When the transverse tube 011 is pressed in, the high temperature melts the brazing material, and when the transverse tubes 011 are interference-fitted, the molten brazing material cools to form a sealing layer to further improve the sealing performance.

[0037] Preferably, the pushing device comprises a pushing cylinder 402 and a pushing rack 403 disposed at the output end of the pushing cylinder 402 , and the two heating heads 401 are disposed on the pushing rack 403 . The pushing rack 403 is used to push the two heating heads 401 .

[0038] Preferably, the two heating heads 401 are electric heating columns, and the ends of the two heating heads 401 are step-shaped structures, and the ends of the step-shaped structures extend into the transverse tube 011, and the step surface of the step-shaped structures abuts against the ends of the transverse tube 011. The electric heating columns are normally open to ensure that they have a sufficient temperature, and the step-shaped structures can not only extend into the transverse tube 011 for heating, but also squeeze the transverse tube 011 to push the radiator unit 01 so that the transverse tube 011 is pressed in.

[0039] Preferably, the support mechanism 20 includes a support frame 201 and baffles 203 disposed on the front and rear sides of the support frame 201. The radiator unit 01 is disposed on the support frame 201 and the front and rear ends of the radiator unit 01 are restrained against the front and rear baffles 203. The baffles 203 are used to restrain the radiator unit 01 to ensure its front and rear position accuracy and avoid front and rear misalignment of the transverse pipe 011.

[0040] Preferably, the support mechanism 20 further includes a sliding guide post 204 disposed at the bottom of the support frame 201, the sliding guide post 204 slides through the machine 10 and a spring 202 is sleeved on the sliding guide post 204, the top and bottom ends of the spring 202 respectively abut against the top of the machine 10 and the bottom of the support frame 201 to apply an upward elastic force to the support frame 201. This solution allows the support mechanism 20 to have a height difference with the heating head 401, so that when manually adding the radiator unit 01, it is away from the heating head 401, thereby reducing the risk of being scalded.

[0041] Preferably, the machine 10 is provided with a support portion for the bottom of the support frame 201 to abut against. When the support frame 201 is pressed down to abut against the support portion, the heating head 401 is coaxial with the horizontal tube 011. When the support mechanism 20 is pressed down to the right position, the horizontal tube 011 is at the same height as the heating head 401. When the radiator unit 01 is added, the support frame 201 is lifted up by the spring 202.

[0042] Preferably, the pressing mechanism comprises a pressing cylinder 300 and a pressing seat 303 arranged at the output end of the pressing cylinder 300, a mounting groove is arranged at the bottom of the pressing seat 303, a horizontal guide column 304 in the left and right directions is arranged in the mounting groove, two pressing blocks 305, 306 are arranged on the horizontal guide column 304 at intervals and slidingly, and an adjusting spring 307 is sleeved on the horizontal guide column 304, and the two ends of the adjusting spring 307 are against the two pressing blocks 305, 306. When pressing down, the two pressing blocks 305, 306 press down two adjacent radiator units 01 respectively, and at this time, the cross tube 011 is in an uninserted state, so when the heating head 401 pushes the left radiator unit 01, the left radiator unit 01 needs to move a certain distance to the right, at this time, the pressing blocks 305, 306 slide on the horizontal guide column 304 to adjust the position, and when the pressing is finished, the adjusting spring 307 pushes the two pressing blocks 305, 306 to the left and right ends of the mounting groove.

[0043] Preferably, the bottom of the pressing blocks 305, 306 matches the top shape of the radiator unit 01. This solution is used to adapt to the radiator unit 01 to be welded and improve the degree of fit during pressing.

[0044] Preferably, the abutting mechanism 50 comprises an abutting cylinder 501 and an L-shaped abutting plate 502 arranged at the output end of the abutting cylinder 501. The abutting cylinder 501 is a multi-position cylinder. The abutting mechanism 50 is used to provide sufficient force to prevent the radiator unit 01 from sliding left and right when the cross pipe 011 is pressed in, so that the cross pipe 011 cannot be pressed in.

[0045] As a preferred embodiment, a material unloading mechanism 60 is further included, which includes a material pushing device arranged at the rear side of the machine platform 10 and a material receiving platform 70 arranged at the front side of the machine platform 10 and opposite to the material pushing device. The material pushing mechanism includes a material pushing cylinder 601 and a material pushing plate 602 arranged at the output end of the material pushing cylinder 601, and the baffle 203 extends to the left side of the material pushing plate 602. The material unloading mechanism 60 is used to automatically push out the welded radiator to reduce manual participation.

[0046] It should be noted that, in this embodiment, each cylinder can be replaced by a hydraulic cylinder.

[0047] The above is a detailed introduction to the title of a direct welding assembly device for a die-cast aluminum radiator provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the present invention and its core ideas.
