Description

Technical Field

[0001] The utility model is a copper diffusion welding machine, belonging to the technical field of diffusion welding. Background Technique

[0002] Diffusion welding is a special welding process, especially suitable for the connection between refractory metals, dissimilar metals and composite materials. During the diffusion welding process, under specific temperature and pressure conditions, through micro-plastic deformation or the generation of a small amount of liquid phase at the interface, the atoms of the materials to be welded are closely contacted, and atomic diffusion and penetration occur, thereby forming a strong metallurgical bond.

[0003] The copper diffusion welding machine adopts this diffusion welding technology to weld copper materials or components containing copper. However, at present, a copper platform is generally used in the copper diffusion welding machine for welding. During the welding process, since the copper platform is directly in contact with water and air, it is easily affected by oxidation, resulting in a decline in the performance of the platform. And the large current required during welding may exacerbate the electro-erosion phenomenon, causing serious damage to the platform, resulting in very frequent repair operations on the platform, thus affecting the production efficiency, and the manpower required for repair will increase the production cost.

Through the second lifting device, the movable frame 4 is driven to move up and down. The second lifting device can adopt the first hydraulic cylinder 2;

[0026] Symmetrically install two round rods 31 located behind the second lifting device on the upper end of the movable frame 4, so that the round rods 31 extending into the top frame 3 at the upper end are slidably connected to the top frame 3. The two round rods 31 are used in cooperation to guide the movement of the movable frame 4, and the bottom frame 8 located below the movable frame 4 is arranged on the lower side of the front end of the main body 1. Then, the fixed frame 7 located directly below the movable frame 4 is installed on the upper end of the bottom frame 8. Through the bottom frame 8, an installation carrier is provided for the fixed frame 7;

[0027] The first mounting plates with their two lower end faces coinciding with the lower end face of the chassis 8 are respectively installed on the left and right ends of the chassis 8.

And the second mounting plates with their two lower end faces coinciding with the lower end face of the main body 1 are respectively arranged on the left and right ends of the main body 1. Through the second mounting plates, a mounting carrier is provided for the second adjusting foot cups;

[0028] A plurality of first adjusting foot cups are equidistantly arranged on the lower end of the first mounting plate. The plurality of first adjusting foot cups cooperate to lift the chassis 8. And the second adjusting foot cups with their lower end faces coinciding with the lower end faces of the first adjusting foot cups are equidistantly installed on the lower end of the second mounting plate. The plurality of second adjusting foot cups cooperate to lift the main body 1. The first adjusting foot cups and the second adjusting foot cups cooperate to increase the stability of the placement of the main body 1;

[0029] The fixing frame 7 located directly below the movable frame 4 is installed on the upper end of the chassis 8. And the two graphite platforms 5 are respectively arranged on the lower end of the movable frame 4 and the upper end of the fixing frame 7. The movable frame 4 and the fixing frame 7 cooperate to provide a mounting carrier for the graphite platforms 5. Then the two relatively arranged graphite jigs 6 are respectively arranged on the inner ends of the two graphite platforms 5 facing each other. Through the graphite jigs 6, the copper products are positioned, and the graphite platforms 5 are used for welding operations.

[0030] Before use, first install the two graphite platforms 5 on the lower end of the movable frame 4 and the upper end of the fixing frame 7 respectively. Then select two suitable graphite jigs 6 and respectively arrange them on the inner ends of the two graphite platforms 5 facing each other;

[0031] During use, place the two copper products to be welded on the two graphite jigs 6 for positioning respectively. Then start the first hydraulic cylinder 2, which further drives the movable frame 4 to move downward, so that the upper graphite platform 5 and the upper graphite jig 6 located above move downward, and then the two placed copper products come into contact with each other. Then start the main body 1, and then perform a pressing and hot welding operation between the two mutually contacting copper products. By using the graphite platform 5 instead of the traditional copper platform, the service life is extended, the number of repair operations is effectively reduced, the production efficiency is improved, and the repair labor is saved, so that the cost can be effectively reduced.

[0032] As Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, on the left and right end faces of the graphite jig 6, inward depressions are formed to form card slots 63. Through the card slots 63, a card mounting space is provided for the card plates 61. The two card plates 61 extending into the card slots 63 are respectively installed on the left and right ends of the graphite jig 6. The two card plates 61 cooperate to restrict the installation of the graphite jig 6;

[0033] The two first plates 41 are respectively mounted on the left and right ends of the movable frame 4, and the second plates 71 are respectively mounted on the left and right ends of the fixed frame 7.

The annular plate 44 is installed on the inner end of the fixed part of the first lifting device whose movable part extends into the annular plate 44, and the annular plate 44 is attached to the outer end of the clamping plate 61. The first lifting device is restrictedly connected to the clamping plate 61 through the annular plate 44. The rod of the fastening bolt 43 whose cap is attached to the inner end of the clamping plate 61 penetrates the through groove 62 and is threadedly connected to the movable part of the first lifting device. The fastening bolt 43 is driven to move up and down through the first lifting device. The first lifting device can use the second hydraulic cylinder 42.

[0035] When the graphite jig 6 needs to be replaced, the second hydraulic cylinder 42 is first started to drive the fastening bolt 43 to move inward, thereby separating the cap of the fastening bolt 43 from the clamping plate 61, and then the clamping plate 61 is pulled outward to make the through slot 62 and the rod of the fastening bolt 43 move relative to each other, thereby separating the clamping plate 61 from the clamping slot 63, thereby releasing the restriction on the graphite jig 6, and then the graphite jig 6 is replaced;

[0036] After the graphite jig 6 is replaced, the clamping plate 61 is pushed inward so that the clamping plate 61 is clamped into the clamping groove 63, and then the second hydraulic cylinder 42 is used to squeeze the cap of the fastening bolt 43 and the clamping plate 61 to tighten and install the clamping plate 61, thereby restricting the installation of the graphite jig 6 and realizing quick disassembly and assembly of the graphite jig 6 for easy use.

[0037] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
