Description

Technical Field

[0001] This invention relates to the field of reaction mold technology for cable fusion welding, specifically to a reaction mold for fusion welding of universal copper-aluminum conductor cables. Background Technology

[0002] Cable fusion welding reaction molds, often called exothermic welding molds or hot melt welding molds, are special tools that use chemical reactions to generate high temperatures to achieve permanent connections between cables or metal components.

[0003] When using a cable fusion welding reaction mold, the cable is fixed after the mold is closed and welding flux is added for fusion welding. Existing molds mostly use fixed-size structures to fix the cable, which can only be used for single-specification cables. Copper cables and aluminum cables have different wire diameters, making it difficult to use the same mold universally. Molds need to be changed frequently during construction. Furthermore, during the fusion welding reaction, the high-temperature impact generated by the burning welding flux causes the copper and aluminum cables to expand due to heat. In addition, it is difficult to maintain precise alignment of the cable ends when the mold is closed. The cable joint is prone to axial movement or radial displacement, which prevents the molten metal from uniformly covering the cable ends. This results in quality problems such as incomplete weld joints, increased porosity, decreased strength, and increased resistance.

[0004] To address the aforementioned issues, we propose an adaptive reaction mold for melting and welding universal copper-aluminum conductor cables. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adaptive reaction mold for melting and welding universal copper-aluminum conductor cables. The device automatically clamps the cable by driving an arc-shaped extrusion plate through mold closing linkage, so that the clamping force is adaptively adjusted according to the wire diameter. This ensures that the ends of the copper-aluminum cable are always precisely aligned with the center of the solution encapsulation tank, effectively preventing axial movement of the cable joint due to thermal expansion or external disturbance during the melting and welding process. It also ensures that the high-temperature molten metal uniformly encapsulates the cable ends, thereby obtaining a high-quality welded joint with fewer pores, high strength, and low resistance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adaptive copper-aluminum conductor universal cable fusion welding reaction mold, comprising a fixing clamp, wherein a first module and a second module are respectively fixedly installed on the two clamps of the fixing clamp, and a material guide groove is provided on the top of the first module and the second module, and a wire fixing groove is provided on the lower surface of the first module and the second module perpendicular to the material guide groove. Two storage slots are embedded on opposite sides of the inner wall of the wire fixing slot in the first module. The wire fixing slot in the second module has an embedded slot on one side of each of the storage slots. Each of the storage slots is equipped with a compression adaptation component. The extrusion adaptation component includes two inclined trapezoidal grooves formed on one side of the inner wall of the storage tank block. Guide trapezoidal blocks are slidably installed on the inner walls of the two inclined trapezoidal grooves. A moving block is fixedly installed on the surface of the two guide trapezoidal blocks. An arc-shaped extrusion plate is fixedly installed on the side of the moving block surface near the guide groove. An extrusion groove is formed on the side of the moving block surface away from the arc-shaped extrusion plate. An extrusion rod is slidably installed inside the extrusion groove. A pulling component is provided on the side of the moving block surface away from the arc-shaped extrusion plate.

[0007] Furthermore, the material guide trough includes an upper conical storage trough section and a lower solution guide trough section. The solution guide trough section has a solution encapsulation trough section at the position of the linear fixing trough. The two material guide troughs can be combined to form a complete cavity.

[0008] Furthermore, a protective groove block is rotatably installed at the top edge of the first module. The protective groove block can cover the surfaces of the first and second modules, and the two line fixing grooves can be combined to form a hole for fixing the cable.

[0009] Furthermore, two storage troughs are respectively set on opposite sides of the guide trough, and an embedded groove is set on one side of the storage trough, with the embedded groove corresponding to the storage trough.

[0010] Furthermore, the inclination direction of both inclined trapezoidal grooves is towards the line fixing groove. With the limiting guidance of the inclined trapezoidal grooves and the guide trapezoidal block, the moving block moves towards the line fixing groove. The arc-shaped extrusion plate bends towards the line fixing groove, and the arc surface of the arc-shaped extrusion plate faces the inside of the storage groove block. The end of the arc-shaped extrusion plate is an arc head, which clamps and fixes the cable in the line fixing groove with an arc structure.

[0011] Furthermore, a stabilizing guide rod is fixedly installed inside the corresponding inclined trapezoidal groove. The wall of the stabilizing guide rod penetrates the surface of the guide trapezoidal block, causing the guide trapezoidal block to slide along the stabilizing guide rod. A reset spring is sleeved on the lower side of the stabilizing guide rod wall. The reset force of the reset spring keeps the moving block away from the fixed groove of the line body.

[0012] Furthermore, the extrusion chute is a trapezoidal trough when viewed from above, with its inclined surface close to the storage block. The extrusion rod is a rod with an inclined end, and its inclination direction and angle are the same as the inclined surface of the extrusion chute. A contact ball is embedded in the side of the extrusion rod close to the extrusion chute. The contact ball is used to reduce the friction between the extrusion rod and the extrusion chute. Under the action of the inclined surface of the extrusion chute, the extrusion rod, in conjunction with the moving block, tends to move towards the guide trough. This tendency, combined with the guiding effect of the inclined trapezoidal trough, causes the arc-shaped extrusion plate to produce a squeezing and pushing effect on the cable, thereby avoiding the impact on welding quality caused by the fixed displacement of the cable in the traditional welding process.

[0013] Furthermore, the pulling component includes a connecting groove formed on one side of the surface of the moving block, and a right-angled trapezoidal block is fixedly installed on the inner wall of the connecting groove near the extrusion groove. An L-shaped extrusion bar is slidably arranged on the inclined surface of the right-angled trapezoidal block. The L-shaped extrusion bar has a movable cavity inside, and a movable block is slidably installed inside the movable cavity. A connecting square rod is fixedly installed on the side of the movable block away from the storage tank block, while several tension springs are fixedly installed on the side of the movable block closer to the storage tank block.

[0014] Furthermore, the connecting groove is located at the corner of the moving block, and the side of the right-angled trapezoidal block closest to the storage tank block is inclined. The bending position of the L-shaped extrusion bar is inclined, and the inclined surface is in parallel contact with the inclined surface of the right-angled trapezoidal block. When the right-angled trapezoidal block approaches the line fixing groove, the extrusion force of the inclined surface drives the L-shaped extrusion bar to move closer to the interior of the storage tank block. Furthermore, one end of each of the tension springs is fixedly connected to one side of the inner wall of the movable cavity. The end of the connecting square rod and the extrusion inclined rod near the inner groove is integrally formed with a vertical anchor block. The anchor block is embedded inside the second module to ensure the stability of the connecting square rod and the extrusion inclined rod in use, and to avoid affecting the internal structure of the first module by utilizing the internal structure of the storage groove block.

[0015] Compared with the prior art, the present invention provides an adaptive copper-aluminum conductor universal cable fusion welding reaction mold, which has the following beneficial effects: 1. This device automatically clamps the cable by driving the arc-shaped extrusion plate through mold clamping linkage, so that the clamping force is adaptively adjusted according to the wire diameter, ensuring that the end of the copper and aluminum cable is always accurately positioned in the center of the solution wrapping tank. This effectively prevents the wire joint from axially moving due to thermal expansion or external disturbance during the molten welding process, and ensures that the high-temperature molten metal uniformly wraps the cable end, thereby obtaining a high-quality welded joint with fewer pores, high strength, and low resistance.

[0016] 2. This device utilizes the arc head of the arc-shaped extrusion plate and its own deformation to provide sufficient friction to prevent slippage when clamping copper and aluminum conductors, avoid local stress concentration that could damage the softer aluminum conductor surface, take into account the differences between copper and aluminum materials, and achieve non-destructive adaptive clamping.

[0017] 3. The device uses the inclined surfaces of the extrusion groove and the extrusion bar to cooperate, and the right-angled trapezoidal block and the L-shaped extrusion bar to extrude. After the mold is closed, it maintains a self-locking state under the locking force of the fixed clamp, so that the arc extrusion plate applies a continuous and stable radial clamping force to the cable throughout the process, avoiding the loosening of the clamping caused by the impact of welding reaction.

[0018] 4. The device is equipped with a reset spring in the inclined trapezoidal groove. After the welding is completed and the mold is opened, the inclined surface thrust disappears, and the reset spring pushes the moving block to slide in the opposite direction, so that the arc extrusion plate automatically retracts and releases the clamping. No manual prying is required, which avoids damage to the inner cavity of the mold and effectively extends the service life of the mold.

[0019] 5. The device integrates the extrusion adaptation component inside the storage tank block. The connecting square rod and the end of the extrusion inclined rod are integrally formed anchor blocks embedded in the second module. A rotating contact ball is embedded in one side of the extrusion inclined rod to reduce sliding friction, ensure smooth mold closing and opening, reduce wear, and ensure clamping accuracy and welding quality during long-term use.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 10 This embodiment of an adaptive copper-aluminum conductor universal cable melting welding reaction mold includes a fixing clamp 1. The two clamps of the fixing clamp 1 are respectively fixedly installed with a first module 2 and a second module 3. The top of the first module 2 and the second module 3 are both provided with a material guide groove 4. The material guide groove 4 includes an upper conical material storage groove section 401 and a lower solution material guide groove section 402. The solution material guide groove section 402 is provided with a solution wrapping groove section 403 at the position of the line fixing groove 5. The two material guide grooves 4 can be combined to form a complete cavity. The lower surface of the first module 2 and the second module 3 are both provided with a line fixing groove 5 perpendicular to the material guide groove 4. A protective groove block 201 is rotatably installed at the top edge of the first module 2. The protective groove block 201 can cover the surface of the first module 2 and the second module 3. The two line fixing grooves 5 can be combined to form a hole for fixing the cable.

[0024] Two storage slots 6 are embedded in the opposite sides of the inner wall of the wire fixing groove 5 in the first module 2. The wire fixing groove 5 in the second module 3 is provided with an embedded groove 7 on one side of several storage slots 6. The two storage slots 6 are respectively set on opposite sides of the guide groove 4. The embedded groove 7 is set on one side of the storage slot 6 and corresponds to the storage slot 6. The interior of several storage slots 6 is provided with a compression adaptation component 8.

[0025] The extrusion adaptation component 8 includes two inclined trapezoidal grooves 801 formed on one side of the inner wall of the storage tank block 6. Guide trapezoidal blocks 802 are slidably installed on the inner walls of the two inclined trapezoidal grooves 801. A moving block 803 is fixedly installed on the surface of the two guide trapezoidal blocks 802. An arc-shaped extrusion plate 804 is fixedly installed on the side of the moving block 803 near the guide groove 4. The inclination direction of the two inclined trapezoidal grooves 801 is towards the line fixing groove 5. With the limiting and guiding of the inclined trapezoidal grooves 801 and the guide trapezoidal blocks 802, the moving block 803 moves towards the line fixing groove 5. The arc-shaped extrusion plate 804 bends towards the side of the line fixing groove 5. The arc surface of the arc-shaped extrusion plate 804 faces the interior of the storage tank block 6. The end of the arc-shaped extrusion plate 804 is an arc head, which clamps and fixes the cable in the line fixing groove 5 with an arc structure.

[0026] A stabilizing guide rod 8011 is fixedly installed inside the corresponding inclined trapezoidal groove 801. The rod wall of the stabilizing guide rod 8011 penetrates the surface of the guide trapezoidal block 802, causing the guide trapezoidal block 802 to slide along the stabilizing guide rod 8011. A return spring 8012 is sleeved on the lower side of the rod wall of the stabilizing guide rod 8011. The return force of the return spring 8012 keeps the moving block 803 away from the line fixing groove 5.

[0027] An extrusion groove 805 is provided on the side of the moving block 803 away from the arc-shaped extrusion plate 804. An extrusion rod 806 is slidably installed inside the extrusion groove 805. The extrusion groove 805 is a trapezoidal groove when viewed from above, with its inclined surface close to the storage block 6. The extrusion rod 806 is a rod with an inclined end, and its inclination direction and angle are the same as the inclined surface of the extrusion groove 805. A contact ball 8061 is embedded and rotated on the side of the extrusion rod 806 close to the extrusion groove 805. The contact ball 8061 is used to reduce the friction between the extrusion rod 806 and the extrusion groove 805. Under the action of the inclined surface of the extrusion groove 805, the moving block 803 tends to move towards the guide groove 4 in conjunction with the extrusion rod 806. This tendency, combined with the guiding effect of the inclined trapezoidal groove 801, causes the arc-shaped extrusion plate 804 to produce an extrusion and pushing effect on the cable, thereby avoiding the impact on welding quality caused by the fixed displacement of the cable in the traditional welding process.

[0028] A pulling component 9 is provided on the side of the surface of the movable block 803 away from the arc-shaped extrusion plate 804. The pulling component 9 includes a connecting groove 901 opened on one side of the surface of the movable block 803. A right-angled trapezoidal block 902 is fixedly installed on the inner wall of the connecting groove 901 near the extrusion groove 805. An L-shaped extrusion bar 903 is slidably provided on the inclined surface of the right-angled trapezoidal block 902. The L-shaped extrusion bar 903 has an internal movable cavity 904, and a movable block 905 is slidably installed inside the movable cavity 904. A connecting square rod 906 is fixedly installed on the side of the movable block 905 away from the storage tank block 6, while several tension springs 907 are fixedly installed on the side of the movable block 905 close to the storage tank block 6. The connecting groove 901 is located at the corner of the moving block 803. The side of the right-angled trapezoidal block 902 close to the storage tank block 6 is inclined. The bending position of the L-shaped extrusion bar 903 is inclined, and the inclined surface is in parallel contact with the inclined surface of the right-angled trapezoidal block 902. When the right-angled trapezoidal block 902 approaches the line fixing groove 5, the extrusion force of the inclined surface drives the L-shaped extrusion bar 903 to move closer to the interior of the storage tank block 6.

[0029] One end of each of the tension springs 907 is fixedly connected to one side of the inner wall of the movable cavity 904. The connecting square rod 906 and the extrusion inclined rod 806 are integrally formed with vertical anchor blocks at the ends near the embedded groove 7. The anchor blocks are embedded inside the second module 3 to ensure the stability of the connecting square rod 906 and the extrusion inclined rod 806 in use, and to avoid affecting the internal structure of the first module 2 by utilizing the internal structure of the storage groove block 6.

[0030] The working principle of the above embodiments is as follows: When the device is in use, before the first module 2 and the second module 3 are closed, the reset spring 8012 is in its natural state, pushing the guide trapezoidal block 802 and the moving block 803, so that the moving block 803 is in a position away from the wire fixing groove 5. At this time, most of the arc extrusion plate 804 is retracted into the storage groove block 6. In this way, when the cable to be welded is placed into the wire fixing groove 5, the arc extrusion plate 804 will perform preliminary positioning. The operator places the cables to be welded into the wire fixing grooves 5 of the first module 2 and the second module 3 respectively, and aligns the cable ends with the solution encapsulation groove section 403 on the lower side of the guide groove 4. Then, when the first module 2 and the second module 3 are closed relative to each other, the extrusion slant bar 806 and the L-shaped extrusion slant bar 903 located on the inner wall of the second module 3 extend into the extrusion slant groove 805 and the connecting groove 901 of the storage block 6 in the first module 2, respectively. The inclined end face of the extrusion slant bar 806 cooperates with the inclined surface of the extrusion groove 805. As the mold closes deeper, the extrusion slant bar 806, pushed by the inclined surface, forces the moving block 803 to move in the direction of the guide groove 4. At the same time, the inclined bend of the L-shaped extrusion slant bar 903 contacts the inclined surface of the right-angled trapezoidal block 902. The right-angled trapezoidal block 902 slides relative to the L-shaped extrusion slant bar 903, generating a force toward the line fixing groove 5. Under the combined action of the two inclined surfaces, the moving block 803 overcomes the elastic force of the return spring 8012 and moves toward the line fixing groove 5 along the guiding direction of the stabilizing guide bar 8011 and the inclined trapezoidal groove 801. The moving block 803 drives the arc-shaped extrusion plate 804 to extend out of the storage slot block 6. Its arc-shaped end extrudes the cable placed in the line fixing slot 5 from both sides. Due to the arc surface structure and arc head design of the arc extrusion plate 804, the cable is evenly clamped and fixed in the center position of the line fixing slot 5. This device can ensure that the joint spacing of the cable is not too large during the welding process, thus adapting to the welding of universal copper and aluminum conductor cables and achieving reliable clamping of cables of different specifications. After the mold is closed, under the pressure of the fixed clamp 1 and the L-shaped extrusion bar 903 and the inclined surface of the right trapezoidal block 902, the first module 2 and the second module 3 can be stably fixed, thus preventing the moving block 803 from retracting. Therefore, a continuous clamping force is always applied to the cable during the welding process, effectively avoiding displacement caused by cable heating or external disturbance. After the welding reaction is completed and cooled, the mold is opened, the first module 2 and the second module 3 are separated, the extrusion bar 806 and the L-shaped extrusion bar 903 are withdrawn from the storage tank 6, and the inclined surface thrust is lost. The return spring 8012 releases its elastic force, pushing the guide trapezoidal block 802 and the moving block 803 to slide in the opposite direction along the stabilizing guide rod 8011, so that the arc-shaped extrusion plate 804 retracts into the storage tank 6, automatically releasing the clamp on the cable, making it easy to take out the welded joint. This device highlights the innovative structure, and the existing mature structures such as the first module 2, the second module 3, the fixing clamp 1 and the guide groove 4 will not be described in detail.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
