[0002] Diffusion welding is a solid-state welding method that applies pressure to the workpiece at high temperature without producing visible deformation or relative movement. In a diffusion welding machine, the workpiece is placed in the welding chamber, and a gas-liquid pressurization mechanism is used to provide pressure during the diffusion welding process, so that the workpiece fits tightly together.

[0003] For example, CN205904567U discloses a new type of energy-saving polymer diffusion welding machine, which includes a control box and an operation panel connected to the control box. The lower electrode and the transformer are respectively set on the left and right sides of the top of the control box. A cylinder is set on the top of the lower electrode, and a booster cylinder is connected to the cylinder. The upper electrode is connected to the output shaft of the cylinder. The lower electrode and the upper electrode are electrically connected to the two poles of the transformer through connecting pieces. The control box contains a controller, a frequency converter, a cooling system and a hydraulic system. The controller and the frequency converter are electrically connected.

[0004] In the prior art, when the gas-liquid pressurization mechanism drives the graphite to contact the workpiece, each welding will cause a certain amount of friction on the graphite surface. As the number of welding times increases, the graphite surface will gradually wear down. The worn graphite cannot conduct heat evenly, which will cause uneven heating during welding and affect the quality of the workpiece. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that as the number of welding cycles increases, the graphite surface will gradually wear down, and the worn graphite cannot conduct heat evenly, which will cause uneven heating during welding. Therefore, a gas-liquid pressurization mechanism for copper diffusion welding machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a gas-liquid boosting mechanism for a copper diffusion welding machine, comprising a boosting component, the boosting component comprising a cylinder, a boosting cylinder mounted on one side of the cylinder, a connecting shaft fixedly connected to one end of the cylinder, a support seat slidably connected to the outside of the connecting shaft, a guide rod slidably connected to one side of the support seat, a buffer mechanism mounted on one end of the connecting shaft, a replacement mechanism mounted on one side of the buffer mechanism, the replacement mechanism comprising a welding graphite block, insertion slots provided on both sides of the welding graphite block, a fixing plate inserted into the insertion slot, a first fixing bolt fixedly connected to one side of the fixing plate, a support plate connected to one side of the fixing plate via the first fixing bolt, a first slot provided at one end of the support plate, and a second fixing bolt installed inside the first slot.

[0007] Preferably, a second slot is provided on one side of the fixing plate, a sliding column is fixedly connected inside the second slot, a support frame is slidably connected outside the sliding column, and one end of the support frame is fixedly connected to one end of the support plate.

[0008] Preferably, a first spring is provided between the support frame and the second slot, and the first spring is sleeved on the outside of the sliding column.

[0009] Preferably, the buffer mechanism includes a first connecting plate, one side of which is fixedly connected to one end of a connecting shaft, and a pressure plate is fixedly connected to the other side of the first connecting plate. A pressure sensor is installed on one side of the pressure plate.

[0010] Preferably, each of the four corners of the first connecting plate is fixedly connected to a positioning rod, and the positioning rod is slidably connected to a second connecting plate.

[0011] Preferably, the positioning rod is sleeved with an elastic sheet, and the two ends of the elastic sheet are respectively installed on one side of the first connecting plate and one side of the second connecting plate.

[0012] Preferably, a pressure head is fixedly connected to the other side of the second connecting plate, a conductive electrode is installed on one side of the pressure head, and both sides of the pressure head are fixedly connected to the support plate by second fixing bolts.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by rotating the first fixing bolt, the support plate is separated from the fixing plate, the first spring in the extended state recovers its deformation, and drives the fixing plate to move to separate from the insertion slot, thereby removing and replacing the worn insertion slot, realizing the quick replacement of the insertion slot, and preventing the continued use of the worn insertion slot from causing uneven welding heat.

[0015] 2. In this utility model, the pressurizing component drives the welding graphite block to move until it contacts the workpiece. The pressure pushes the second connecting plate to slide on the positioning rod. The pressure acts on the elastic sheet, causing the elastic sheet to undergo elastic deformation.

At the same time, the pressure sensor inside the pressure plate can detect the pressure during the pressurizing process of the pressurizing component and adjust the working state of the pressurizing component to ensure welding quality.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a gas-liquid boosting mechanism for a copper diffusion welding machine, including a boosting component 1. The boosting component 1 includes a cylinder 11, a boosting cylinder 12 installed on one side of the cylinder 11, a connecting shaft 15 fixedly connected to one end of the cylinder 11, a support seat 13 slidably connected to the outside of the connecting shaft 15, a guide rod 14 slidably connected to one side of the support seat 13, a buffer mechanism 3 installed at one end of the connecting shaft 15, a replacement mechanism 2 installed on one side of the buffer mechanism 3, the replacement mechanism 2 includes a welding graphite block 21, and insertion slots 24 are provided on both sides of the welding graphite block 21. A fixing plate 22 is inserted into the insertion slot 24. A first fixing bolt 25 is fixedly connected to one side of the fixing plate 22. A support plate 27 is connected to one side of the fixing plate 22 via the first fixing bolt 25. A first slot 29 is opened at one end of the support plate 27, and a second fixing bolt 28 is installed inside the first slot 29. A second slot 211 is opened on one side of the fixing plate 22. A sliding column 210 is fixedly connected inside the second slot 211. A support frame 26 is slidably connected to the outside of the sliding column 210. One end of the support frame 26 is fixedly connected to one end of the support plate 27. A first spring 212 is provided between the support frame 26 and the second slot 211. The first spring 212 is sleeved on the outside of the sliding column 210.

[0024] The cylinder 11 and the booster cylinder 12 work together, and the pressure drives the connecting shaft 15 to move, which in turn moves the replacement mechanism 2 to apply pressure to the weldment, so that the weldment fits tightly at high temperature and the welding is achieved. The welding graphite block 21 wears during the pressing process. By rotating the first fixing bolt 25, the support plate 27 is separated from the fixing plate 22. The first spring 212, which is in an extended state, returns to its original shape and drives the support frame 26 to slide outside the sliding column 210. The fixing plate 22 moves to separate from the insertion groove 24, thereby removing and replacing the worn insertion groove 24. This allows for quick replacement of the insertion groove 24 and prevents the continued use of the worn insertion groove 24, which would cause uneven heating during welding.

[0025] Example 2: Figure 1 and Figure 3 As shown, the buffer mechanism 3 includes a first connecting plate 31, one side of which is fixedly connected to one end of the connecting shaft 15, and a pressure plate 36 is fixedly connected to the other side of the first connecting plate 31. A pressure sensor is installed on one side of the pressure plate 36. Positioning rods 34 are fixedly connected to the four corners of the first connecting plate 31, and a second connecting plate 32 is slidably connected to the outside of the positioning rods 34. An elastic sheet 35 is sleeved on the outside of the positioning rods 34, and the two ends of the elastic sheet 35 are respectively installed on one side of the first connecting plate 31 and one side of the second connecting plate 32. A pressure head 33 is fixedly connected to the other side of the second connecting plate 32. A conductive electrode 23 is installed on one side of the pressure head 33, and both sides of the pressure head 33 are fixedly connected to the support plate 27 by second fixing bolts 28.

[0026] The overall effect of this embodiment is that when the pressurizing component 1 works and drives the replacement mechanism 2 and the buffer mechanism 3 to move downward, the welding graphite block 21 moves to contact the workpiece, the pressure pushes the second connecting plate 32 to slide on the positioning rod 34, the pressure acts on the elastic sheet 35, causing the elastic sheet 35 to undergo elastic deformation, the elastic sheet 35 will generate an elastic force opposite to the direction of the pressure, thereby resisting the increase of pressure, slowing down the speed of pressure rise, and preventing the workpiece from being damaged by excessive instantaneous pressure. The pressure sensor installed inside the pressure plate 36 can detect the pressure during the pressurizing process of the pressurizing component 1, adjust the working state of the pressurizing component 1, and ensure the welding quality.

[0027] The device is used and operates as follows: The cylinder 11 and the booster cylinder 12 work, driving the connecting shaft 15 to move, which in turn moves the replacement mechanism 2 to apply pressure to the weldment, causing it to fit tightly together at high temperatures. When the booster assembly 1 moves the replacement mechanism 2 and the buffer mechanism 3 downwards, the welding graphite block 21 moves to contact the weldment. The pressure pushes the second connecting plate 32 to slide on the positioning rod 34. The pressure acts on the elastic sheet 35, causing it to deform elastically and slowing down the rate of pressure increase. The pressure sensor inside the pressure plate 36 can detect the pressure during the booster assembly 1's pressurization process. After welding is completed, by rotating the first fixing bolt 25, the support plate 27 is separated from the fixing plate 22. The first spring 212, which is in an extended state, returns to its original shape, and the fixing plate 22 moves to separate from the insertion slot 24, thereby removing and replacing the worn insertion slot 24.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
