Description
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 is a device used for heating. It has heat pipes and heat sinks. The heat sinks are fixed to the heat plate to improve the heat dissipation efficiency. Radiators are widely used in various civil and public buildings such as residential buildings, offices, hotels, shopping malls, hospitals, schools, 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. At present, 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 tube 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 become loose and leak during use. Therefore, welding becomes the first choice. There is no welding equipment for multiple radiator units on the market, and manual participation is too much, which is inefficient. In addition, since the heat sink spacing of the radiator unit is small, the traditional automatic welding device will be blocked and the horizontal tubes of this type of radiator cannot be welded.

[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 like 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 type assembly device. The technical solution adopted by the present invention to solve the above technical problems is: a die-cast aluminum radiator direct welding type assembly device, such as Figure 1-6 As shown, the radiator includes several radiator units 01, each radiator unit 01 has two transverse pipes 011 to be welded, which include:
[0032] Machine 10;
[0033] A support mechanism 20 is provided on the machine platform 10 and is used to support the radiator unit 01;
[0034] The pressing mechanism 30 is provided on the machine platform 10 and includes a front pressing device 301 and a rear pressing device 302 that are symmetrical in front and back. Each pressing device includes two pressing seats 303 that can slide relative to each other and are driven by a lifting cylinder to simultaneously rise and fall.
[0035] The heating and pushing mechanism 40 is disposed on the machine 10 and is located to the left of the support mechanism 20. It includes a pushing device and two heating heads 401 disposed 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, causing the end of the transverse tube 011 to expand due to the heat.
[0036] The abutment mechanism 50 is provided 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 can squeeze the left transverse tube 011 and extend it into the right transverse tube 011 that has expanded due to heat. 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, which greatly improves the efficiency and sealing effect. 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 solder protruding from the groove can be provided in the groove. When the transverse tube 011 is pressed in, the high temperature causes the solder to melt. When the transverse tubes 011 are interference-fitted, the molten solder cools to form a sealing layer, further improving the sealing performance.
[0037] Preferably, the pushing device includes a pushing cylinder 402 and a pushing rack 403 provided at the output end of the pushing cylinder 402 , and the two heating heads 401 are provided 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 with stepped ends that extend into the transverse tube 011, with the stepped surface of the stepped structure resting against the end of the transverse tube 011. The electric heating columns are normally open to ensure a sufficient temperature, and the stepped structure not only extends into the transverse tube 011 for heating, but also squeezes the transverse tube 011, pushing the radiator unit 01 into the transverse tube 011.
[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, ensuring its front and rear position accuracy and preventing the cross pipe 011 from being misaligned.
[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 platform 10 and is sleeved with a spring 202. The top and bottom ends of the spring 202 respectively abut against the top of the machine platform 10 and the bottom of the support frame 201, exerting an upward spring force on the support frame 201. This arrangement creates a height difference between the support mechanism 20 and the heating head 401, allowing manual insertion of the radiator unit 01 away from the heating head 401, thereby reducing the risk of burns.
[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 and abuts against the support portion, the heating head 401 and the cross tube 011 are coaxial. Only when the support mechanism 20 is pressed down into place, the cross tube 011 and the heating head 401 are at the same height. When the radiator unit 01 is added, the support frame 201 is lifted up by the spring 202.
[0042] Preferably, the pressing mechanism includes a pressing cylinder 300 and a pressing seat 303 arranged at the output end of the pressing cylinder 300. The bottom of the pressing seat 303 is provided with a mounting groove, and a horizontal guide column 304 in a left and right direction is provided in the mounting groove. Two pressing blocks 305 and 306 are spaced and slidably provided on the horizontal guide column 304, and an adjusting spring 307 is sleeved on the horizontal guide column 304. The two ends of the adjusting spring 307 are against the two pressing blocks 305 and 306. When pressing down, the two pressing blocks 305 and 306 press down two adjacent radiator units 01 respectively. At this time, the cross tube 011 is in an uninserted state. Therefore, 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 and 306 slide on the horizontal guide column 304 to adjust the position. When the pressing is completed, the adjusting spring 307 pushes the two pressing blocks 305 and 306 to the left and right ends of the mounting groove.
[0043] Preferably, the bottom of the pressing blocks 305, 306 matches the shape of the top 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 abutment mechanism 50 includes an abutment cylinder 501 and an L-shaped abutment plate 502 disposed at the output end of the abutment cylinder 501. The abutment cylinder 501 is a multi-position cylinder. The abutment mechanism 50 is used to provide sufficient force when the cross tube 011 is pressed in to prevent the radiator unit 01 from sliding left or right, which would prevent the cross tube 011 from being pressed in.
[0045] Preferably, the machine further includes a blanking mechanism 60, which includes a pusher device disposed at the rear side of the machine 10 and a receiving platform 70 disposed at the front side of the machine 10 and opposite to the pusher device. The pusher mechanism includes a pusher cylinder 601 and a pusher plate 602 disposed at the output end of the pusher cylinder 601. The baffle 203 extends to the left side of the pusher plate 602. The blanking mechanism 60 is used to automatically push out the welded radiator, reducing manual intervention.
[0046] It should be noted that, in this embodiment, each air 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. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified. These improvements and modifications also fall within the scope of protection of the claims of the present invention.
