Description

Technical Field

[0001] The invention relates to the technical field of cold-sprayed copper, in particular to a cold-sprayed copper device and a method for reinforcing a multi-point-connected copper-aluminum transition line clamp. Background Art

[0002] The copper-aluminum transition piece in the equipment wire clamp is a type of equipment wire clamp. It is an essential accessory for connecting the copper and aluminum materials of high and low voltage lines. The existing products are mainly manufactured through friction welding, brazing, flash welding and other technologies. In order to avoid defects such as bonding force deviation during welding, easy breakage under external force, and high-temperature oxides on the welding surface, cold copper spraying technology has begun to be applied to the connection of copper-aluminum transition wire clamps.

[0003] During use, cold spraying requires the use of a cold spray machine. When spraying, the cold spray machine's pipeline delivers air pressure and powdered raw materials into the spray gun, and the spray gun sprays out powdered raw materials that fall to the place where they need to be connected to complete the connection. When connecting the cold spray machine pipeline and the spray gun, the common methods are threaded or flange connections. When connecting the two methods, the sealing completely relies on the sealing ring, and both are fixed by threads. After multiple disassembly, the threads are greatly worn and are prone to loosening. In addition, high-pressure gas is sprayed out of the pipeline, which is prone to pressure release due to loose fixing, affecting the final copper spraying effect. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figure 1-2 , is the first embodiment of the present invention, which provides a cold copper spraying device, which can quickly achieve the effect of fixing the first flange 105 and the second flange 106, and includes a supporting component 100, including a supporting platform 101, a workpiece 102 to be processed arranged on the supporting platform 101, a cold spraying machine 103 arranged on the outer side of the supporting platform 101, a spray gun 104 arranged on the cold spraying machine 103, an air pipe arranged on the spray gun 104, a first flange 105 arranged on the spray gun 104, and a second flange 106 arranged on the air pipe; a fixing component 200, It includes a sealing component 201 arranged on the first flange 105, and a limiting component 202 arranged on the second flange 106; a sealing reinforcement component 300, including a pushing component 301 arranged in the limiting component 202, a transmission component 302 arranged on the pushing component 301, an anti-loosening component 303 arranged on the transmission component 302, and a clamping component 304 arranged on the first flange 105; a reinforcement component 400, including an air guide component 401 arranged on the anti-loosening component 303, and an anti-slipping component 402 arranged on the first flange 105.

[0030] Specifically, a clamp for clamping the workpiece 102 to be processed is provided on the support table 101, so that the workpiece 102 to be processed will not fall. The cold spray machine 103 is connected to the spray gun 104 through a pipe 301e. The pipe 301e is divided into two (the two pipes 301e are wrapped together), one provides air pressure for the spray gun 104, and the other provides copper powder for the spray gun 104. The air pressure allows the material to be sprayed onto the workpiece 102 to be processed at a high speed for cold spraying (copper). The copper spraying here refers to the spraying of copper powder, and not only copper can be sprayed here, but other metal powders can also be sprayed depending on the workpiece 102 to be processed. The support table 101, the cold spray machine 103 and the cold spraying of copper for the workpiece are all existing technologies and will not be elaborated here.

[0031] Furthermore, the sealing assembly 201 includes an annular groove 201a arranged on the first flange 105 and the second flange 106, and an annular sealing ring 201b is fixedly connected in the annular groove 201a; the limiting assembly 202 includes a plurality of mounting plates 202a fixedly connected to the second flange 106, the first flange 105 is provided with a plurality of sockets 202b cooperating with the mounting plates 202a, two mounting cavities 202c are provided in the mounting plate 202a, and the left and right ends of the mounting cavity 202c are provided with through openings 202d, the height of the through opening 202d is less than the height of the mounting cavity 202c, a slider 202e is penetrated and slidably connected in the through opening 202d, a top block 202f cooperating with the mounting cavity 202c is fixedly connected to the slider 202e, the slider 202e is elastically connected to the inner wall of the mounting cavity 202c through a first spring 202g, and a slope 202h is provided on the slider 202e.

[0032] It should be noted that the annular sealing ring 201b abuts against each other to achieve sealing between the first flange 105 and the second flange 106. Since the height of the through-hole 202d is smaller than the height of the installation cavity 202c, the top block 202f can abut against the inner wall of the installation cavity 202c to prevent the slider 202e from detaching from the installation cavity 202c.

[0033] During use, when the spray gun 104 needs to be fixed to the pipe 301e, it is only necessary to insert the mounting plate 202a on the second flange 106 into the socket 202b on the first flange 105. In this process, the inclined surface 202h on the slider 202e on the mounting plate 202a first abuts against the socket 202b, and the slider 202e moves toward the mounting cavity 202c and compresses the first spring 202g. When the slider 202e completely passes over the socket 202b, the slider 202e protrudes to the outside of the mounting cavity 202c under the action of the first spring 202g. At this time, the side wall of the slider 202e abuts against the side wall of the first flange 105 to prevent the mounting plate 202a from being separated from the socket 202b, thereby achieving the fixation between the first flange 105 and the second flange 106. The setting of the top block 202f prevents the slider 202e from completely protruding to the through-hole 202 d, when the first flange 105 and the second flange 106 are fixed, the annular sealing ring 201b realizes the sealing between the first flange 105 and the second flange 106. When the first flange 105 and the second flange 106 need to be disassembled, it is only necessary to press the slider 202e to move the slider 202e into the installation cavity 202c, and then pull the second flange 106. Of course, since there are multiple pairs of sliders 202e, an extrusion piece that always cooperates with the slider 202e can be set, so that multiple sliders 202e can be pressed into the installation cavity 202c at one time. The shape of the extrusion piece here is not fixed, as long as multiple sliders 202e can be pressed into the installation cavity 202c at the same time (for example, an extrusion piece composed of a circular ring and multiple wedge blocks, when in use, press the circular ring down to allow multiple wedge blocks to resist the slider 202e).

[0034] In summary, by setting the fixing component 200, when fixing the first flange 105 and the second flange 106, it is only necessary to insert the mounting plate 202a on the second flange 106 into the socket 202b on the first flange 105, so as to achieve the fixing of the first flange 105 and the second flange 106, which is easy to use.

[0035] Example 2, reference Figure 1 to Figure 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a sealing reinforcement component 300 of the cold copper spraying device, which solves the problem of how to strengthen the seal between the first flange 105 and the second flange 106. It includes a pushing component 301, including a circular cavity 301a arranged in the mounting plate 202a, a disc 301b is sealingly and slidably connected in the circular cavity 301a, and the disc 301b is elastically connected to the inner wall of the circular cavity 301a through a second spring 301c. An air inlet 301d is provided at the lower end of the circular cavity 301a, and a pipe 301e matching the air inlet 301d is provided on the second flange 106; the transmission component 302 includes an arc-shaped plate 302a fixedly connected to the disc 301b, an arc-shaped opening 302b is provided on the arc-shaped plate 302a, a connecting shaft 302c is slidably connected in the arc-shaped opening 302b, and a U-shaped plate 302d is fixedly connected to the connecting shaft 302c.

[0036] Specifically, the disc 301b is sealed and slidably connected to the inner wall of the circular cavity 301a, and the air inlet 301d is connected to the pipe 301e, so that part of the high-pressure gas during cold copper spraying will enter the air inlet 301d. The arc plates 302a here are arranged in pairs, and the arc ports 302b are symmetrically arranged.

[0037] Furthermore, the anti-loosening assembly 303 includes two mounting grooves 303a arranged on the mounting plate 202a, and a plug block 303b is slidably connected in the mounting groove 303a. A slot 303c cooperating with the plug block 303b is provided on the first flange 105. The mounting cavity 202c is provided with a strip-shaped opening 303d communicating with the circular cavity 301a. An L-shaped plate 303e cooperating with the strip opening 303d is fixedly connected to the U-shaped plate 302d, and the L-shaped plate 303e is fixedly connected to the plug block 303b. The clamping assembly 304 includes a An annular cavity 304a is disposed on the first flange 105, the annular cavity 304a is communicated with the inner end slot 303c, the outer end of the annular sealing ring 201b extends into the annular cavity 304a, a wedge ring 304b is fixedly connected to the annular sealing ring 201b, a guide groove 304c is provided at the top of the annular cavity 304a, a guide block 304d is slidably connected in the guide groove 304c, an arc-shaped pressure plate 304e is fixedly connected to the guide block 304d, and a cutting edge 304f is provided on the arc-shaped pressure plate 304e to cooperate with the wedge ring 304b.

[0038] It should be noted that the U-shaped plate 302d is slidably connected to the strip-shaped opening 303d, and the outer end of the annular sealing ring 201b extends into the annular cavity 304a, so that when the arc-shaped pressure plate 304e moves, it can also squeeze the annular sealing ring 201b, further preventing the loosening of the annular sealing ring 201b. Although the gas enters the pipe 301e and will be instantly divided into two pressures, the amount of gas required in the pipe 301e is small, and during cold spraying, the first step will be debugged (spray once to make sure it can continue spraying). At this time, the gas required by the pipe 301e has been provided, and will not affect the subsequent continuous spraying.

[0039] When in use, during cold copper spraying, due to the high-pressure gas in the pipe 301e, the gas also enters the air inlet 301d, causing the disc 301b to move upward, and the second spring 301c to compress. When the disc 301b moves upward, it can drive the arc plate 302a to move upward, causing the arc mouth 302b to move upward. When the arc mouth 302b moves upward, it can drive the connecting shaft 302c to move toward the slot 303c, so that the U-shaped plate 302d moves toward the slot 303c, causing the L-shaped plate 303e to move toward the slot 303c, driving the plug 303b to enter the slot 303c, further avoiding the square The arc plate becomes loose, making the fixation between the first flange 105 and the second flange 106 more stable. When the inner end plug 303b is inserted into the slot 303c, the arc pressure plate 304e can be pushed to move toward the wedge ring 304b, so that the cut edge 304f on the arc pressure plate 304e is against the cut edge 304f on the wedge ring 304b. At this time, the wedge ring 304b can be squeezed, making the wedge ring 304b tend to move downward, thereby squeezing the annular sealing ring 201b to prevent the annular sealing ring 201b from leaking. When the arc pressure plate 304e moves, the guide block 304d slides in the guide block 304d for guidance.

[0040] In summary, by providing the sealing reinforcement component 300, when the spray gun 104 is working, high-pressure gas can be allowed to enter the pipeline 301e, and the plug block 303b can be inserted into the slot 303c through transmission to reinforce the first flange 105 and the second flange 106. Moreover, by providing the clamping assembly 304, when the plug block 303b is inserted into the slot 303c, the annular sealing ring 201b can be reinforced to ensure the sealing effect between the first flange 105 and the second flange 106.

[0041] Example 3, reference Figure 1 to Figure 4, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a reinforcement component 400 of the cold spray copper device, which solves the problem of how to further prevent the first flange 105 and the second flange 106 from loosening. It includes an air guide component 401, including an air guide pipe 401a arranged in the outer end slot 303c, and two branch pipes 401b are arranged on the air guide pipe 401a. A sealing plate 401c is sealingly and slidably connected in the slot 303c, and the sealing plate 401c is connected through the third The spring 401d is elastically connected to the inner wall of the slot 303c; the anti-drop assembly 402 includes two first arc grooves 402a arranged on the first flange 105, and the slider 202e is provided with a second arc groove 402b that cooperates with the first arc groove 402a. An arc strip 402c is slidably connected in the first arc groove 402a, and the arc strip 402c is elastically connected to the inner wall of the first arc groove 402a through the fourth spring 402d, and the two branch pipes 401b are both connected to the first arc groove 402a.

[0042] Specifically, one branch pipe 401b is connected to the first arc groove 402a at the outer end, and the other branch pipe 401b bypasses the first arc groove 402a at the outer end and is connected to the first arc groove 402a at the inner end. The curvature of the first arc groove 402a and the second arc groove 402b here are both greater than 120° and less than 160°, so that when the arc strip 402c moves into the second arc groove 402b, the arc strip 402c and the second arc groove 402b can be prevented from being separated.

[0043] When in use, when the slider 202e protrudes to achieve the fixation between the first flange 105 and the second flange 106, the first arc groove 402a is directly opposite to the second arc groove 402b, and then when the outer end plug block 303b is inserted into the slot 303c, it can also push the sealing plate 401c to move, thereby pumping the gas at the outer end of the slot 303c into the air guide pipe 401a, and finally pumping it into the two first arc grooves 402a through the two branch pipes 401b, pushing the arc plate 302a to move, and the arc plate 302a moves into the second arc groove 402b, and the arc of movement in the second arc groove 402b is greater than 90°. At this time, the inner side wall of the arc groove is against the inner wall of the second arc groove 402b, so that the slider 202e will not move by itself, ensuring the stability of the slider 202e, thereby ensuring the stability of the fixation between the first flange 105 and the second flange 106.

[0044] In summary, by setting the reinforcement component 400, when the plug block 303b is inserted into the slot 303c, it can also push the sealing plate 401c to pump the gas at the outer end of the slot 303c into the first arc groove 402a, and push the arc plate 302a to move into the second arc groove 402b to prevent the slider 202e from moving, thereby ensuring the stability of the fixation between the first flange 105 and the second flange 106.

[0045] Embodiment 4 is the fourth embodiment of the present invention. Different from the previous embodiment, this embodiment provides a multi-point connection copper-aluminum transition line clamp reinforcement method, including placing the workpiece 102 to be processed on the support platform 101 and fixing it; selecting the spray gun 104 required; fixing the second flange 106 on the air pipe of the cold spray machine 103 and the first flange 105 on the spray gun 104; turning on the spray gun 104 and directing the spray gun 104 to perform multi-point spraying at the points that require cold spraying; and removing the workpiece 102 to be processed after spraying is completed.
