Description

Technical Field

[0001] This invention belongs to the field of extrusion equipment technology, specifically a soft and hard copper and aluminum extrusion production equipment. Background Technology

[0002] Soft and hard copper-aluminum refer to two different hardness or strength grades of copper and aluminum alloy materials. For their forming process, extrusion is usually used. Extrusion molding is completed with extrusion equipment, followed by extrusion after heating and melting to achieve high-temperature extrusion and cooling solidification.

[0003] In existing soft and hard copper-aluminum extrusion production equipment, molten metal is typically fed into the extrusion cavity and extruded. However, during actual use, the gradually solidifying extruded metal product rubs against the inner wall of the extrusion cavity, making the surface of the formed product prone to scratches. Furthermore, after shutdown, some residual molten metal cools and solidifies in the forming cavity and is fixed on the inner wall, hindering subsequent extrusion and affecting the molding quality. In summary, current extrusion production equipment still suffers from surface scratches and residues hindering extrusion, resulting in low actual extrusion production quality.

[0004] Furthermore, during the extrusion molding and simultaneous cooling process of soft and hard copper and aluminum extrusion equipment, the cooling water itself is affected by the infiltration of air dust. When cooling and heat exchange occurs in the high-temperature range, the cooling water heats up significantly. Over long-term use, scale forms in the cooling chamber, increasing the heat exchange wall thickness, thereby reducing the subsequent heat exchange efficiency, affecting the extrusion molding and curing speed of metal products, and resulting in poor performance. Summary of the Invention

[0005] The purpose of this invention is to provide a soft and hard copper-aluminum extrusion production equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a soft and hard copper-aluminum extrusion production equipment, comprising an extrusion section, an extruder, and a sleeve hole opened inside the extrusion section. One end of the extrusion section is connected to the extruder. A forming inner cylinder assembly is rotatably fitted inside the sleeve hole. A surface treatment assembly is movably nested in the inner wall of the forming inner cylinder assembly. A rotating part is rotatably provided at the right end of the extrusion section. The outer end of the surface treatment assembly is movably installed on the front side of the surface treatment assembly. The rotating part drives the surface treatment assembly to rotate synchronously. The surface treatment assembly moves in and out of the inner wall of the forming inner cylinder assembly.

[0007] The molded inner cylinder assembly includes a rotating cylinder and a notch or groove formed inside the rotating cylinder;

[0008] The surface treatment assembly includes a scraper, a connecting crank, and a first electric push rod. The scraper is movably nested in a notch. One end of the connecting crank is fixedly connected to the scraper, and the other end is fixedly connected to the movable end of the first electric push rod.

[0009] The rotating part includes a gear disk and an assembly groove. The gear disk is rotatably installed at the right end of the extrusion part. The first electric push rod is fixed in the assembly groove. The assembly groove is used to realize the fixed assembly of the first electric push rod. A certain length is reserved inside the assembly groove to ensure the insertion of the connecting crank rod and to allow the connecting crank rod to move in the assembly groove, thus reserving space for driving the scraper rod to move.

[0010] Preferably, the molding inner cylinder assembly further includes a fixing ring and a cooling arc cavity. The fixing ring is fixedly sleeved on the outer surface of the rotating cylinder and rotatably sleeved inside the extrusion section. The fixing rings are symmetrically distributed on both sides of the outer surface of the rotating cylinder. The cooling arc cavity is opened on the outer surface of the rotating cylinder and located between the two sets of fixing rings.

[0011] Preferably, the rotating cylinder is rotatably sleeved in the sleeve hole, and the cooling arc cavity is located outside the notch groove.

[0012] Preferably, the top and bottom surfaces of the scraper are both arc-shaped. The top arc-shaped surface of the scraper is adapted to the arc-shaped surface of the inner wall of the rotating cylinder. The connecting curved rod is located on the outer side of the right end of the extrusion section. The scraper cleans the inner wall of the rotating cylinder, and the arc-shaped surface increases the contact area with the inner wall of the rotating cylinder, improving the scraping effect. In addition, the top arc-shaped surface is adapted to the arc-shaped surface of the inner wall of the rotating cylinder, ensuring that the inside of the rotating cylinder maintains a good circular inner cavity when nested.

[0013] Preferably, the right end of the extrusion section has an annular cavity, the gear disk is rotatably fitted in the annular cavity, the assembly groove is opened on the front side of the gear disk, one end of the connecting crank is slidably fitted in the assembly groove, the annular cavity is used to assemble the gear disk, the gear disk rotates to realize the independent rotation of the surface treatment component and the synchronous rotation of the surface treatment component and the forming inner cylinder component, which is controlled by whether the scraper is nested or not. The power unit provides rotational power, and the locking screw is used to fix the rotating cylinder, ensuring that the scraper will not drive the rotating cylinder to rotate when it rotates and rubs against the inner wall of the rotating cylinder, thus realizing cleaning under relative motion.

[0014] Preferably, a power unit is provided in the inner wall of the extrusion section, and the power unit drives the meshing gear disk to rotate through the drive gear on the output shaft.

[0015] Preferably, the extrusion section has an installation cavity and a reserved cavity respectively. The reserved cavity is symmetrically distributed on both sides of the cooling arc cavity. The installation cavity is located outside the reserved cavity. The two ends of the reserved cavity are respectively connected to the installation cavity and the sleeve hole. The installation cavity and the reserved cavity are provided with a descaling component.

[0016] Preferably, the descaling component includes:

[0017] The second electric push rod is installed in the mounting cavity;

[0018] The movable seat is fixedly connected to the movable end of the second electric push rod and is movably sleeved in the mounting cavity;

[0019] The cleaning part is a flexible cleaning brush, which is fixedly connected to the movable seat via a mounting plate, and the cleaning part is movably located in the reserved cavity.

[0020] Preferably, the top of the extrusion section is provided with a liquid outlet hole, and the bottom of the extrusion section is provided with a liquid inlet hole. Both the liquid outlet hole and the liquid inlet hole are connected to the sleeve hole and are located outside the cooling arc cavity.

[0021] Preferably, the top of the extrusion section is provided with a threaded hole, and a locking screw is threaded into the internal thread of the threaded hole. The locking screw is located above a corresponding fixing ring. The extruder is fixed at the left end of the extrusion section, and the extruder conveys the molten metal liquid to the forming inner cylinder assembly.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention utilizes the cooperation of a rotating part and a surface treatment component to achieve synchronous rotation when the surface treatment component is nested within the inner wall of the molding inner cylinder component. This allows molten metal to be dynamically extruded while remaining within the rotating cylinder, reducing adhesion between the cooled and solidified metal product and the inner wall of the rotating cylinder, thus improving the extrusion effect. On the other hand, when the surface treatment component moves out of the inner wall of the molding inner cylinder component and contacts the inner wall of the rotating cylinder, the rotating cylinder is fixed, causing the rotating part to drive the surface treatment component to rotate independently. This allows for rotational scraping and cleaning of the relatively stationary inner wall of the rotating cylinder, effectively removing residual solid metal fragments adhering to the inner wall. This further reduces the amount of solid particles remaining in the extrusion chamber, ensuring the quality of subsequent extrusion molding, and providing good anti-adhesion effects and thorough residue removal, thereby comprehensively improving the quality of extrusion molding.

[0024] 2. This invention utilizes the opening of a cooling arc cavity to store and pass in cooling water, along with a rotating cylinder that rotates, so that the outer surface of the rotating cylinder makes dynamic contact with the cooling water in the cooling arc cavity. During rotation, the heat exchange uniformity of the cooling water is improved. At the same time, the protruding position at the cooling arc cavity automatically agitates the cooling water, providing disturbance to the cooling water, improving the heat absorption effect of the cooling water, accelerating the cooling and molding speed, and resulting in good performance.

[0025] 3. This invention utilizes the rotation of the rotating cylinder, combined with the protrusion at the notch of the cooling arc cavity, to actively clean scale on the inner wall of the corresponding sleeve hole during the rotational cooling process. Simultaneously, with the arrangement of the descaling components, the elastic cleaning part gradually moves to the annular area of ​​the cooling arc cavity and contacts the rotating cylinder during the rotational cooling and molding process. Utilizing the frictional contact under the rotational effect, the scale on the inner wall of the cooling arc cavity is further cleaned. While using cooling water to cool the molten metal during extrusion molding, the cleaning of the inner wall of the cooling cavity is completed simultaneously, reducing scale residue, ensuring good cooling and heat exchange effects, preventing the accumulation of scale and increasing its thickness, resulting in excellent performance.

[0035] 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.

[0036] like Figures 1 to 8 As shown, this embodiment of the invention provides a soft and hard copper-aluminum extrusion production equipment, including an extrusion section 1, an extruder 2, and a sleeve hole 3 opened inside the extrusion section 1. One end of the extrusion section 1 is connected to the extruder 2. A forming inner cylinder assembly 5 is rotatably fitted inside the sleeve hole 3. A surface treatment assembly 6 is movably nested in the inner wall of the forming inner cylinder assembly 5. A rotating part 13 is rotatably provided at the right end of the extrusion section 1. The outer end of the surface treatment assembly 6 is movably installed on the front side of the surface treatment assembly 6. The rotating part 13 drives the surface treatment assembly 6 to rotate synchronously. The surface treatment assembly 6 moves in and out of the inner wall of the forming inner cylinder assembly 5.

[0037] The molded inner cylinder assembly 5 includes a rotating cylinder 51 and a notch 52 formed inside the rotating cylinder 51;

[0038] The surface treatment assembly 6 includes a scraper 61, a connecting crank 62, and a first electric push rod 63. The scraper 61 is movably nested in the notch 52. One end of the connecting crank 62 is fixedly connected to the scraper 61 and the other end is fixedly connected to the movable end of the first electric push rod 63.

[0039] The rotating part 13 includes a gear disk 131 and an assembly groove 132. The gear disk 131 is rotatably mounted at the right end of the extrusion part 1, and the first electric push rod 63 is fixed in the assembly groove 132.

[0040] The first electric push rod 63 is fixedly assembled using the assembly slot 132, and a certain length is reserved inside the assembly slot 63 to ensure the insertion of the connecting crank rod 62 and allow the connecting crank rod 62 to move in the assembly slot 132, leaving space for the movement of the scraper rod 61.

[0041] The molding inner cylinder assembly 5 also includes a fixing ring 53 and a cooling arc cavity 54. The fixing ring 53 is fixedly sleeved on the outer surface of the rotating cylinder 51 and rotatably sleeved inside the extrusion section 1. The fixing rings 53 are symmetrically distributed on both sides of the outer surface of the rotating cylinder 51. The cooling arc cavity 54 is opened on the outer surface of the rotating cylinder 51 and is located between the two sets of fixing rings 53. The rotating cylinder 51 is rotatably sleeved in the sleeve hole 3. The cooling arc cavity 54 is located outside the notch groove 52.

[0042] Molten metal is introduced into the rotating cylinder 51 and extruded outward under pressure. The cooling arc cavity 54 is filled with cooling water to increase the cooling and solidification speed during extrusion. The fixing ring 53 maintains the stable rotation of the rotating cylinder 51 and avoids axial displacement.

[0043] The top and bottom surfaces of the scraper 61 are both arc-shaped. The arc-shaped top surface of the scraper 61 is adapted to the arc-shaped inner wall surface of the rotating cylinder 51. The connecting rod 62 is located on the outer side of the right end of the extrusion section 1.

[0044] The scraper 61 cleans the inner wall of the rotating cylinder 51, and the arc-shaped surface increases the contact area with the inner wall of the rotating cylinder 51, improving the scraping effect. In addition, the top arc-shaped surface is adapted to the arc-shaped surface of the inner wall of the rotating cylinder 51, ensuring that the inside of the rotating cylinder 51 maintains a good circular cavity when nested.

[0045] The right end of the extrusion section 1 has an annular cavity 4, in which the gear disk 131 is rotatably sleeved. The assembly groove 132 is opened on the front of the gear disk 131, and one end of the connecting crank 62 is slidably sleeved in the assembly groove 132. The inner wall of the extrusion section 1 has a power unit 7, which drives the meshing gear disk 131 to rotate through the drive gear on the output shaft. The top of the extrusion section 1 has a threaded hole 11, and a locking screw 12 is threaded inside the threaded hole 11. The locking screw 12 is located above a fixed ring 53. The extruder 2 is fixed at the left end of the extrusion section 1, and the extruder 2 transports the molten metal liquid to the forming inner cylinder assembly 5.

[0046] The annular cavity 4 is used to assemble the gear disk 131. The gear disk 131 rotates to realize the independent rotation of the surface treatment component 6 and the synchronous rotation of the surface treatment component 6 and the forming inner cylinder component 5. The rotation is controlled by whether the scraper 61 is nested or not. The power unit 7 provides rotational power. The locking screw 12 is used to fix the rotating cylinder 51, ensuring that the scraper 61 will not drive the rotating cylinder 51 to rotate when it rotates and rubs against the inner wall of the rotating cylinder 51, thus realizing cleaning under relative motion.

[0047] Example 1: In use, as the extruder 2 feeds molten metal into the interior of the rotating cylinder 51, the power unit 7 is activated, driving the rotating unit 13 to rotate. The gear disk 131 drives the surface treatment assembly 6 to rotate. The scraper 61, nested in the notch groove 52, drives the rotating cylinder 51 to rotate synchronously. The molten metal in the rotating cylinder 51 cools and solidifies, and is extruded through the right end of the forming rotating cylinder 51. When it is necessary to clean the inner wall of the rotating cylinder 51, first screw the locking screw 12 up, so that the locking screw 12 rotates down along the threaded hole 11 and locks the fixing ring. 53. Clamp and fix the rotating cylinder 51, and start the first electric push rod 63 in the surface treatment assembly 6. The first electric push rod 63 located in the assembly groove 132 pushes the connecting crank rod 62 to move and drives the scraper 61 to move out of the notch groove 52. The arc-shaped end face of the scraper 61 contacts the inner wall of the rotating cylinder 51. Start the power unit 7 again and make the rotating unit 13 rotate. The surface treatment assembly 6 rotates independently in the rotating cylinder 51 and cleans and scrapes along the inner wall of the rotating cylinder 51 to remove residual solids.

[0048] First, by utilizing the cooperation of the rotating part 13 and the surface treatment component 6, synchronous rotation is achieved when the surface treatment component 6 is nested in the inner wall of the molding inner cylinder component 5. This allows the molten metal to be dynamically extruded while remaining in the rotating cylinder 51, reducing the adhesion of the cooled and solidified metal product to the inner wall of the rotating cylinder 51 and improving the extrusion effect. On the other hand, when the surface treatment component 6 moves out of the inner wall of the molding inner cylinder component 5 and contacts the inner wall of the rotating cylinder 51, the rotating cylinder 51 is fixed and the rotating part 13 drives the surface treatment component 6 to rotate independently. This allows for the rotation and scraping of the relatively stationary inner wall of the rotating cylinder 51, effectively removing residual solid metal fragments adhering to the inner wall. This further reduces the amount of solid particles remaining in the extrusion chamber, ensuring the quality of subsequent extrusion molding, and providing good anti-adhesion effect and thorough residue removal, thus comprehensively improving the quality of extrusion molding.

[0049] The extrusion section 1 has an installation cavity 8 and a reserved cavity 9. The reserved cavity 9 is symmetrically distributed on both sides of the cooling arc cavity 54. The installation cavity 8 is located outside the reserved cavity 9. The two ends of the reserved cavity 9 are connected to the installation cavity 8 and the sleeve hole 3, respectively. The installation cavity 8 and the reserved cavity 9 are equipped with a descaling component 10.

[0050] The descaling component 10 includes:

[0051] Electric push rod 101 is installed in mounting cavity 8;

[0052] Movable seat 102 is fixedly connected to the movable end of electric push rod 101 and is movably sleeved in mounting cavity 8;

[0053] The cleaning part 103 is a flexible cleaning brush. The cleaning part 103 is fixedly connected to the movable seat 102 through the mounting plate. The cleaning part 103 is movably located in the reserved cavity 9.

[0054] The flexible cleaning brush is deformable to avoid interfering with the rotation of the rotating cylinder 51, and the cleaning part 103 moves close to the inner wall of the cooling arc cavity 54 to complete the descaling of the inner wall of the cooling arc cavity 54.

[0055] The top of the extrusion section 1 is provided with a liquid outlet hole, and the bottom of the extrusion section 1 is provided with a liquid inlet hole. Both the liquid outlet hole and the liquid inlet hole are connected to the sleeve hole 3 and are located outside the cooling arc cavity 54.

[0056] The outlet and inlet ports are used to form the input and output of cooling water.

[0057] Example 2: During rotary extrusion, cooling water is continuously fed into the cooling arc cavity 54 through the inlet hole. As the rotating cylinder 51 rotates, the molten metal in the rotating cylinder 51 dynamically exchanges heat with the coolant on the outside through the thin-walled rotating cylinder 51, achieving rapid cooling. During the rotation process, the protruding position at the notch of the cooling arc cavity 54 slides along the inner wall of the sleeve hole 3, causing scale to detach from the inner wall of the sleeve hole 3. The second electric push rod 101 in the descaling assembly 10 is activated, causing the movable seat 102 to move the cleaning part 103, which moves into the cooling arc cavity 54. The mounting plate fixed at one end of the cleaning part 103 is always located in the reserved cavity 9, maintaining the rotation of the rotating cylinder 51. The rotating cylinder 51 comes into frictional contact with the elastic cleaning brush, completing the comprehensive descaling.

[0058] First, by utilizing the opening of the cooling arc cavity 54 to store and introduce cooling water, and in conjunction with the rotating cylinder 51, the outer surface of the rotating cylinder 51 is dynamically in contact with the cooling water in the cooling arc cavity 54. During the rotation, the heat exchange uniformity of the cooling water is improved. At the same time, in conjunction with the protruding position at the cooling arc cavity 54, the cooling water is automatically agitated, providing disturbance to the cooling water, improving the heat absorption effect of the cooling water, accelerating the cooling and molding speed, and achieving good results.

[0059] Furthermore, by utilizing the rotation of the rotating cylinder 51 again, and in conjunction with the protrusion at the notch of the cooling arc cavity 54, the cylinder also rotates along the inner wall of the corresponding area of ​​the sleeve hole 3 during the rotational cooling process, thereby actively cleaning the scale on the inner wall of the sleeve hole 3. Simultaneously, in conjunction with the arrangement of the descaling component 10, during the rotational cooling molding process, the elastic cleaning part 103 gradually moves to the annular area of ​​the cooling arc cavity 54 and contacts the rotating cylinder 51. Utilizing the frictional contact under the rotational effect, the scale on the inner wall of the cooling arc cavity 54 is further cleaned by friction. When using cooling water to cool the molten metal for extrusion molding, the cleaning of the inner wall of the cooling cavity is completed simultaneously, reducing scale residue, ensuring good cooling and heat exchange effect, avoiding the accumulation of scale and increasing its thickness, resulting in good performance.

[0060] The working principle and usage process of this invention are as follows: During use, as the extruder 2 inputs molten metal into the rotating cylinder 51, the power unit 7 is activated, driving the rotating unit 13 to rotate. The gear disk 131 drives the surface treatment assembly 6 to rotate. The scraper 61, nested in the notch groove 52, drives the rotating cylinder 51 to rotate synchronously. The molten metal in the rotating cylinder 51 cools and solidifies, and is extruded through the right end of the forming rotating cylinder 51. When it is necessary to clean the inner wall of the rotating cylinder 51, first screw the locking screw 12 upwards, causing it to rotate downwards along the threaded hole 11 and clamp the fixing ring 53, thus fixing the rotating cylinder 51. Then, activate the first electric push rod 63 in the surface treatment assembly 6, causing it to push the connecting crank rod 62 to move in the assembly groove 132, and causing the scraper 61 to move out of the notch groove 52, so that the arc-shaped end face of the scraper 61 contacts the inner wall of the rotating cylinder 51. Then, activate the power unit 7 again... The rotating part 13 rotates, causing the surface treatment component 6 to rotate independently within the rotating cylinder 51, cleaning and scraping along the inner wall of the rotating cylinder 51 to remove residual solids. During rotary extrusion, cooling water is continuously supplied to the cooling arc cavity 54 through the inlet hole. As the rotating cylinder 51 rotates, the molten metal in the rotating cylinder 51 dynamically exchanges heat with the coolant on the outside through the thin-walled rotating cylinder 51, achieving rapid cooling. During the rotation process, the protruding position at the notch of the rotating cylinder 51 slides along the inner wall of the sleeve hole 3, causing scale to detach from the inner wall of the sleeve hole 3. The second electric push rod 101 in the descaling component 10 is activated, causing the movable seat 102 to move the cleaning part 103, which moves into the cooling arc cavity 54. The mounting plate fixed at one end of the cleaning part 103 remains in the reserved cavity 9, maintaining the rotation of the rotating cylinder 51. The rotating cylinder 51 comes into frictional contact with the elastic cleaning brush, completing the comprehensive descaling.
