Description

Technical Field

[0001] This invention relates to the field of extrusion equipment technology, and in particular to an intelligent copper busbar extrusion device capable of continuous production. Background Technology

[0002] Copper busbars are key conductors in power transmission and distribution systems. They typically have a rectangular cross-section and are widely used in substations, switchgear, and new energy equipment. Continuous extrusion presses are revolutionary equipment for manufacturing high-quality copper busbars. Through the principle of frictional heat generation and continuous extrusion, they can efficiently transform room-temperature copper rods into copper busbars of unlimited length, with a dense structure and excellent conductivity in a single operation, greatly improving production efficiency, material utilization, and overall product performance.

[0003] For example, patent CN107321807A, entitled "A High-Efficiency Copper Material Extrusion Machine," with an authorization announcement date of November 7, 2017, includes an extrusion roller, an extrusion shoe, a plug, an extrusion port, a die, a sealing block, a pressure roller, and copper material. A worktable is provided at the bottom of the pressure roller, and the extrusion roller is mounted on the worktable via a frame. Support feet are provided at the bottom of the worktable, and a control box and a rotary motor are mounted on the worktable. The extrusion roller is connected to the rotary motor via a drive shaft, and a pressure roller is positioned above the extrusion roller. This invention uses an extrusion roller and an extrusion shoe on a worktable, controlled by a control box. The pressure roller feeds the copper material into the extrusion feed chamber of the extrusion roller, and then the extrusion roller drives the material to rotate, carrying it into the extrusion roller groove for extrusion. The material passes through the sealing block and enters the deformation chamber at the front of the die for deformation extrusion. It then enters the die for final extrusion before being discharged. This method features high speed and high efficiency, thereby improving product quality.

[0004] The shortcomings of the existing technology are that, since changing the mold block requires the material stop that is attached to one side of the extrusion wheel to be flattened by a hydraulic rod, the mold block must be disassembled and replaced manually, and it takes a long time to cool down before the mold block of different specifications can be replaced. After cleaning the blank material remaining in the cavity, the equipment must be preheated before it can be put back into use. This makes the process of changing the mold block cumbersome and has low automation, which affects production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent copper busbar extrusion device capable of continuous production. A second telescopic rod drives a stopper to move downwards, while a first telescopic rod drives a moving component to move the die block. During its movement, the die block cuts off the extruded copper busbar and moves to the end of the stopper. During the reset stroke, the moving component, driven by the first telescopic rod, quickly separates from the die block and moves directly below a pre-reserved die block, causing the pre-reserved die block to fall into the moving component. This achieves automatic filling of the pre-reserved die block, making the die replacement process more automated and avoiding the tedious process of changing dies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a continuously producing intelligent copper busbar extrusion device, comprising a support, an extrusion wheel mounted on the support, and a stopper at one end of the extrusion wheel; the stopper is movably mounted on the support, and a telescopic rod is provided at the bottom end of the stopper, which drives the stopper to move along the axis connecting the stopper and the support; the stopper has a sliding groove, and a moving part is slidably mounted in the sliding groove; a mold block is provided at one end of the moving part, and a telescopic rod is provided at the other end of the moving part, which drives the moving part to move along the sliding groove; when the stopper moves down, the telescopic rod drives the moving part to move the mold block and quickly separate it from the discharge end of the stopper; when the stopper stops, the telescopic rod drives the moving part to separate from the mold block and move back and forth to the placement slot to complete the replacement of the mold block;

[0008] The material stopper is provided with a guide plate at one end, a material stopper block at the bottom of the guide plate, and a cavity between the material stopper block and the guide plate. One end of the cavity is connected to a guide port, which is located on the material stopper.

[0014] The ring has symmetrically formed abutment grooves at one end, and symmetrically formed limit grooves inside the ring. A support column is provided inside the limit groove and is fixed to the limit plate. A locking block is fixedly connected to one end of the support column.

[0015] As a further description of the above technical solution:

[0016] A push rod is fixedly connected to one end of the U-shaped strip near the limiting plate, and the end of the push rod away from the U-shaped strip is movably connected to the telescopic rod.

[0024] It also includes a recycling rack, which is fixed to the material stop. The recycling rack has a protruding strip fixed inside, and the protruding strip is adapted to the abutment groove opened in the support ring. A stop bar is fixed at one end of the recycling rack.

[0025] This invention provides an intelligent copper busbar extrusion device capable of continuous production, which has the following advantages:

This achieves automatic filling of the reserved mold block, making the mold replacement process more automated and avoiding the tedious process of changing molds. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figure 1-9 A continuously producing intelligent copper busbar extrusion device includes a support 1, an extrusion wheel 2 mounted on the support 1, and a stop 3 at one end of the extrusion wheel 2. The stop 3 is movably mounted on the support 1, and a telescopic rod 9 is provided at the bottom of the stop 3. The telescopic rod 9 drives the stop 3 to move along the axis connecting the stop 3 and the support 1. The stop 3 has a sliding groove 311, and a moving part 4 is slidably mounted in the sliding groove 311. A mold block 5 is provided at one end of the moving part 4, and a telescopic rod 8 is provided at the other end of the moving part 4. The telescopic rod 8 drives the moving part 4 to move along the sliding groove 311. When the stop 3 moves down, the telescopic rod 8 drives the moving part 4 to move the mold block 5 and quickly separate it from the discharge end of the stop 3. When the stop 3 stops, the telescopic rod 8 drives the moving part 4 to separate from the mold block 5 and move back and forth to the placement groove 6 to complete the replacement of the mold block 5.

[0039] Specifically, the support 1 is symmetrically distributed at both ends of the extrusion roller 2. Both the extrusion roller 2 and the stop 3 are movably connected to the support 1. When the telescopic rod 9 drives the stop 3 to move along the axis connecting the stop 3 and the support 1, it comes into contact with the pressure roller to form a structure for processing the copper rod. The extrusion roller 2 drives the copper rod towards the stop 3, generating high temperatures through friction. Under these high temperatures, the copper rod becomes a malleable blank. The blank enters the forming groove 51 of the mold block 5 for extrusion molding. When it is necessary to change the mold block 5 to a different size, the telescopic rod 9... The second retraction rod 9 drives the stop 3 to move downwards. At the same time, the first telescopic rod 8 drives the moving part 4 to move the mold block 5. During the movement stroke, the mold block 5 cuts off the extruded copper busbar and moves to the end of the stop 3. During the reset stroke driven by the first telescopic rod 8, the moving part 4 quickly separates from the mold block 5 and moves to directly below the reserved mold block 5, so that the reserved mold block 5 falls into the moving part 4, realizing the automatic filling of the reserved mold block 5. This makes the mold replacement process more automated and avoids the tediousness of changing molds.

[0040] The material stopper 3 has a guide plate 31 at one end, a material stopper 32 at the bottom of the guide plate 31, and a cavity 33 between the material stopper 32 and the guide plate 31. One end of the cavity 33 is connected to a guide port 34, and the guide port 34 is opened on the material stopper. The sliding groove 311 is symmetrically provided with directional strips 35, and the top of the directional strips 35 is fixedly connected to a limit block.

[0041] Specifically, the guide plate 31 in the baffle 3 is used to guide the copper rod and rub it into a malleable state. The cavity 33 between the guide plate 31 and the bottom baffle block 32 is used to collect the malleable blank. The blank squeezed into the cavity 33 is squeezed into the mold through the guide port 34 on the guide, which facilitates the processing of the blank into copper busbars. The sliding groove 311 in the guide is used to limit the movement direction of the moving part 4. The directional strips 35 symmetrically fixed in the sliding groove 311 act on the stability of the movement of the moving part 4 and ensure that the mold block 5 driven by the moving part 4 fits more tightly with the guide, so as to avoid the mold block 5 from being misaligned during the movement and causing gaps, which would affect the yield of copper busbars.

[0042] The movable component 4 includes a U-shaped strip 41, with grooves 411 at both ends of the U-shaped strip 41, which are adapted to the directional strip 35. One end of the U-shaped strip 41 is fixedly connected to a limiting plate 42, and a supporting ring 43 is movably provided in the limiting plate 42. One end of the supporting ring 43 is symmetrically provided with abutment grooves 432, and a limiting groove 431 is symmetrically provided in the supporting ring 43. A support column 421 is provided in the limiting groove 431, and the support column 421 is fixed on the limiting plate 42. One end of the support column 421 is fixedly connected to a locking block 422. A push rod 44 is fixedly connected to the end of the U-shaped strip 41 near the limiting plate 42, and the end of the push rod 44 away from the U-shaped strip 41 is movably connected to the telescopic rod 8.

[0043] Specifically, the U-shaped strip 41 included in the movable component 4 is used to slide within the sliding groove 311. The sliding groove 411 of the U-shaped strip 41 is slidably adapted to the directional strip 35 and is movably connected to the telescopic rod 8 via the push rod 44. When the U-shaped strip 41 is driven to move by the telescopic rod 8, the U-shaped strip 41 first causes the mold block 5 to separate from the guide opening 34 of the communicating cavity 33, and cuts off the copper busbar extruded between the guide opening 34 and the mold block 5. The limiting plate 42 fixedly connected in the U-shaped strip 41 is movably provided with a support ring 43. When the mold block 5 moves to the guide opening 34 within the sliding groove 311, the lock fixedly connected in the limiting plate 42 is engaged. The stop block 422 limits the mold block 5 and, by squeezing the support ring 43, forms a sealed structure between the U-shaped strip 41 and the support ring 43, as well as between the mold block 5 and the guide opening 34. When the U-shaped strip 41 drives the mold block 5 to move towards the recycling rack 7, the protruding strip 71 fixed in the recycling rack 7 abuts against the abutting groove 432 opened in the support ring 43, so that the support ring 43 moves along the direction defined by the limiting plate 42 under the action of the protruding strip 71, that is, the support ring 43 moves towards the mold block 5, so that the support ring 43 lifts the mold block 5 and separates the locking block 422 that is fixedly connected to the limiting plate 42, so as to facilitate the rapid separation of the mold block 5 by the recycling rack 7.

[0044] A forming groove 51 is provided inside the mold block 5. Orientation grooves 52 are symmetrically provided at both ends of the mold block 5. A locking groove 53 is provided at the end of the mold block 5 near the discharge port of the forming groove 51, and the locking groove 53 is adapted to the locking block 422. A protruding rod is symmetrically provided in the placement groove 6, and the protruding rod is adapted to the orientation groove 52. One end of the placement groove 6 is connected to the installation groove 611. A baffle 61 is movably provided in the installation groove 611. A fixing ear 62 is fixedly connected to one end of the baffle 61, and a return spring 64 is fixedly connected to one end of the fixing ear 62. A dial 63 is rotatably provided at the other end of the baffle 61.

[0045] Specifically, the forming groove 51 of the mold block 5 is defined according to the requirements. The directional groove 52 of the mold block 5 is slidably connected to the protruding rod fixed in the placement groove 6, so that the mold block 5 can play a directional and limiting role when it moves towards the moving part 4. A baffle 61 is movably provided in the installation groove 611 of the guide part. The baffle 61 is used to limit the position of the reserved mold block 5 and prevent it from falling into the sliding groove 311 and causing blockage during the stroke of the moving frame moving the mold block 5 towards the recycling frame 7. When the telescopic rod 8 drives the moving part 4 to reset, the moving part 4 abuts against the dial wheel 63 and drives the baffle 61 to retract, so that the reserved mold block 5 limited by the baffle 61 can fall directly into the moving part 4, realizing the quick installation of the reserved mold block 5.

[0046] It also includes a recycling rack 7, which is fixed on the baffle 3. A protruding strip 71 is fixed inside the recycling rack 7, and the protruding strip 71 is adapted to the abutment groove 432 opened in the support ring 43. A stop bar 72 is fixed at one end of the recycling rack 7.

[0047] Specifically, the protruding strip 71 in the recycling rack 7 is used to abut against the support ring 43 to separate the mold block 5 from the locking block 422 in the limiting plate 42. The separated mold block 5 cannot move synchronously with the moving part 4 under the limit of the stop bar 72, so that the moving part 4, driven by the telescopic rod 8, can easily separate the mold block 5 during the reset stroke, so as to achieve the effect of separation and recycling, so as to facilitate the recycling of the mold block 5 and reduce the cumbersomeness of manually changing the mold after cooling in the prior art.

[0048] Working principle: The telescopic rod 29 drives the stop 3 to move along the axis connecting the material and the bracket 1, and merges with the pressure wheel to form a structure for processing copper rods. The extrusion wheel 2 drives the copper rod to move towards the stop 3 and generates high temperature through friction, so that the copper rod becomes a malleable blank under the action of high temperature. The blank enters the forming groove 51 of the mold block 5 for extrusion molding. When it is necessary to change the mold block 5 of different sizes, the telescopic rod 29 drives the stop 3 to move downward. At the same time, the telescopic rod 18 drives the moving part 4 to move the mold block 5. When the U-shaped strip 41 moves under the drive of the telescopic rod 18, the U-shaped strip 41 first drives the mold block 5 to separate from the guide port 34 of the connecting cavity 33, and cuts off the copper busbar extruded between the guide port 34 and the mold block 5. The limiting plate 42 fixedly connected in the U-shaped strip 41 is movably provided with a support ring 43. When the mold block 5 moves to the guide port 34 in the sliding groove 311, the limiting plate 42 is located in the guide port 34. The locking block 422, which is fixedly connected to the mold block 5, limits the mold block 5 and, by squeezing the support ring 43, forms a sealed structure between the U-shaped strip 41 and the support ring 43, as well as between the mold block 5 and the guide opening 34. When the U-shaped strip 41 drives the mold block 5 to move towards the recycling rack 7, the protruding strip 71 fixed in the recycling rack 7 abuts against the abutting groove 432 opened in the support ring 43, so that the support ring 43 moves along the direction limited by the limiting plate 42 under the action of the protruding strip 71, that is, the support ring 43 moves towards the mold block 5, so that the support ring 43 lifts the mold block 5 and separates the locking block 422, which is fixedly connected to the limiting plate 42, so that the recycling rack 7 can quickly separate the mold block 5. When the telescopic rod 8 drives the moving part 4 to return to its original position, the moving part 4 abuts against the dial wheel 63 and drives the baffle 61 to retract, so that the reserved mold block 5 limited by the baffle 61 can fall directly into the moving part 4, so as to realize the quick installation of the reserved mold block 5.
