Description

Technical Field

[0001] The present invention relates to the field of extrusion molding, and particularly to an extruder.

Background Art

[0002] Copper tubes have a wide range of application scenarios. Currently, there are various ways to manufacture copper tubes. For example, they can be directly cast from molten copper or extruded from copper ingots. In the extrusion molding method, extrusion equipment and extrusion dies are used. The extrusion equipment extrudes the copper ingot towards the extrusion die. After passing through the extrusion die, the copper ingot can be formed into a rough tube blank. Some copper materials will remain on the extrusion die after extrusion. At this time, the extrusion die cannot be used to make tubes. It is necessary to remove the copper materials remaining on the extrusion die before it can be used again. Therefore, the extrusion die needs to be replaced. However, the replacement of the extrusion die is relatively complex and time-consuming, which will affect the production progress of the tubes.

Detailed implementation manners

[0047] The technical solutions of the embodiments of the present invention will be explained and illustrated below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0048] Words such as "exemplary" and "some embodiments" appearing hereinafter mean "serving as an example, an embodiment or an illustration". Any embodiment described as "exemplary" does not have to be construed as superior to or better than other embodiments. In order to better illustrate the present invention, numerous specific details are given in the following specific implementation manners. Those skilled in the art should understand that the present disclosure can also be implemented without some specific details.

[0049] Referring to Figures 1 to 10 , the present invention discloses an extruder, which includes a machine base 100. A die seat body 200 is provided on the machine base 100. An extrusion die 210 is provided on the die seat body 200. An extrusion device 120 and a discharging device 130 are provided on the machine base 100 on both sides of the die seat body 200 in the axial direction of the extrusion die 210. A die mounting groove 220 for mounting the extrusion die 210 is provided on the die seat body 200. There are two die mounting grooves 220. A translation device 300 for connecting the die seat body 200 is provided on the side of the machine base 100. After one extrusion is completed, the translation device 300 acts to drive the die seat body 200 to translate and change the die mounting groove 220 corresponding to the extrusion device 120.

[0050] During the process of tube material extrusion forming, a copper ingot is placed between the extrusion device 120 and the extrusion die 210. The extrusion device 120 extrudes the copper ingot towards the extrusion die 210, so that the copper ingot is pressed and passes through the extrusion die 210 to form a rough tube blank. The rough tube blank is removed from the discharging device 130. When the stroke of the extrusion device 120 reaches the maximum value, one round of tube material extrusion forming ends. At this time, part of the copper ingot still remains on the extrusion die 210. The extruder can cut the tube material to separate the tube material from the extrusion die 210. The translation device 300 can move the die seat body 200 after one extrusion is completed, so that another extrusion die 210 moves between the extrusion device 120 and the discharging device 130, and the extrusion die 210 with remaining material is removed from between the extrusion device 120 and the discharging device 130, so that the next round of extrusion forming can be immediately started, reducing the waiting process and improving the extrusion forming efficiency. During the extrusion forming process, the extrusion die 210 with remaining material can be removed from the die seat body 200 and a new extrusion die 210 can be replaced.

[0051] The extrusion device 120 includes a hydraulic cylinder 121 and an extrusion column 122 driven by the hydraulic cylinder 121. The hydraulic cylinder 121 can generate a large force, thereby driving the extrusion column 122 to move to extrude the copper ingot to produce a tube blank. The discharge device 130 includes a discharge port 131 and a sawing device arranged next to the discharge port 131. The sawing device cuts off the tube material after the tube material is formed to a certain length, or cuts off the tube material when the copper ingot cannot be further extruded and the extrusion device 120 needs to be reset.

[0052] The translation device 300 includes a translation push rod 310 and a translation machine base 320. The translation push rod 310 is arranged on the translation machine base 320 and connected to the mold base 200. The translation push rod 310 is telescopic relative to the translation machine base 320 to drive the mold base 200 to translate. The translation push rod 310 can perform telescopic movement to move synchronously with the mold base 200 during the movement. By setting the stroke of the translation push rod 310, the displacement distance of the mold base 200 can be adjusted so that the extrusion mold 210 can be aligned with the extrusion device 120 and the discharge device 130. The translation machine base 320 can maintain the position of the translation push rod 310 so that the translation push rod 310 moves in the horizontal direction. A device for providing power to the translation push rod 310 is also provided on the side of the base 100, for driving the translation push rod 310 to perform telescopic movement, wherein the telescopic movement of the translation push rod 310 means that the translation push rod 310 itself can be telescoped and change its own length; or, the translation push rod 310 can move relative to the translation base 320.

[0053] After the translation device 300 moves the die base 200, the extrusion die 210 needs to be replaced, and the replacement position is close to the extrusion device 120 and the discharge device 130. In order to reduce safety hazards, the extruder also includes a die disassembly device, which includes a toggle device 400 arranged on the side of the extrusion device 120. The toggle device 400 moves to push the extrusion die 210 to remove the extrusion die 210 from the die base 200. The toggle device 400 is used to remove the extrusion die 210 from the die base 200. In this way, the operator does not need to manually remove the extrusion die 210, so as to free up manpower and reduce safety hazards. The limiter cannot block the movement of the extrusion die 210 toward the extrusion device 120. The toggle device 400 can push the extrusion die 210 to make the extrusion die 210 move relative to the die base 200, thereby removing the extrusion die 210 from the die base 200.

[0054] A conveyor belt 110 for conveying the extrusion die 210 is provided on the side of the machine base 100. The conveyor belt 110 is arranged below the die base body 200. The die disassembly device also includes a clamping device 410 for clamping the extrusion die 210. The clamping device 410 is arranged between the shifting device 400 and the translation device 300. The shifting device 400 pushes the extrusion die 210 toward the clamping device 410 so that the extrusion die 210 is translated onto the clamping device 410. Since the conveyor belt 110 is located below the die base body 200, the shifting device 400 cannot directly push the extrusion die 210 from the die base body 200 to the conveyor belt 110. By providing the clamping device 410, the shifting device 400 can transfer the extrusion die 210 to the clamping device 410.

[0055] The toggle device 400 includes a retractable toggle rod 401, which has a columnar pusher 402 and a hook-shaped pusher 403. The columnar pusher 402 is used to push the extrusion die 210 on the die base 200 toward the clamping device 410, and the hook-shaped pusher 403 is arranged below the columnar pusher 402 and is used to push the extrusion die 210 on the clamping device 410 toward the conveyor belt 110. The toggle rod 401 can do telescopic movement to push the extrusion die 210. When the toggle rod 401 is extended, the columnar pusher 402 can push the extrusion die 210 to make the extrusion die 210 leave the die base 200. When the toggle rod 401 is retracted, the hook-shaped pusher 403 can push the extrusion die 210 to make the extrusion die 210 leave the clamping device 410 and move to the conveyor belt 110, so that the extrusion die 210 is conveyed by the conveyor belt 110.

[0056] The toggle device 400 further includes a toggle seat 404, on which a toggle rod 401 is rotatably disposed, and on which a push rod 405 is hingedly connected to the toggle rod 401, and the push rod 405 can be extended and retracted relative to the toggle rod 401 to drive the toggle rod 401 to rotate relative to the toggle seat 404. During the extension and retraction process, the push rod 405 can drive the wave lever to flip relative to the toggle seat 404, thereby avoiding the mold seat 200 that is translated to above the conveyor belt 110, and allowing the hook-shaped push head 403 to avoid the extrusion mold 210 located on the clamping device 410.

[0057] To prevent the extrusion die 210 from tipping over during extrusion and ensure that the residue stripping device can securely hold the extrusion die 210 to remove the residue, it is necessary to ensure that the movement of the extrusion die 210 is a translational movement during the process from the die seat 200 to the clamping device 410 and from the clamping device 410 to the conveyor belt 110. The clamping device 410 includes a clamping seat 411, a first clamping arm 412, and a second clamping arm 413. The first clamping arm 412 is fixedly connected to the clamping seat 411, and the second clamping arm 413 is rotatably connected to the clamping seat 411. At least three clamping supports 414 are provided on the first clamping arm 412 and the second clamping arm 413 and are distributed in the circumferential direction of the extrusion die 210. A driven roller 415 is rotatably mounted on the clamping support 414. The second clamping arm 413 can flip relative to the first clamping arm 412 to adjust the distance between the two to clamp the extrusion die 210 and maintain the stability of the extrusion die 210. By clamping and supporting the extrusion die 210 with at least three clamping supports 414, the stability of the extrusion die 210 during movement can be maintained, preventing the extrusion die 210 from tipping over and making it inconvenient to transfer the extrusion die 210 outwards from the conveyor belt 110. The driven roller 415 can be driven to rotate during the translational movement of the extrusion die 210, reducing the friction between the extrusion die 210 and the clamping support 414 and improving the smoothness of the movement of the extrusion die 210.

[0058] On the conveyor belt 110, there is also a loading platform 111 for carrying the extrusion die 210.

[0059] On the side of the machine base 100, there is a residue separation device 500 for stripping the residue on the extrusion die 210. After the die disassembly equipment disassembles the extrusion die 210 from the die seat 200, it places the extrusion die 210 on the conveyor belt 110 and conveys the extrusion die 210 to the residue separation device 500 through the conveyor belt 110. On the side of the residue separation device 500, there is a die pushing device 600 for pushing the extrusion die 210 towards the residue separation device 500. The conveyor belt 110 is located between the residue separation device 500 and the die pushing device 600.

[0060] The die disassembly equipment can disassemble the extrusion die 210 with residue from the die seat 200, place the disassembled extrusion die 210 on the conveyor belt 110, and convey it to the residue separation device 500 through the conveyor belt 110. When the extrusion die 210 is conveyed to the residue separation device 500, the residue separation device 500 automatically strips the residue. The die pushing device 600 can convey the extrusion die 210 on the conveyor belt 110 towards the residue separation device 500, enabling the extrusion die 210 with residue to move onto the residue separation device 500 for residue stripping treatment.

[0061] The surplus material separation device 500 includes a separation base body 510. A clamping mechanism 520 for clamping the extrusion die 210 and a surplus material cutting device 530 that moves in the height direction to cut the surplus material are provided on the separation base body 510. Surplus material peeling arms 540 for peeling the surplus material outward are further provided on both sides of the clamping mechanism 520. A surplus material push rod 550 corresponding to the center of the extrusion die 210 is further provided on one side of the clamping mechanism 520 in the axial direction of the extrusion die 210. The clamping mechanism 520 can clamp the extrusion die 210 during the process of peeling the surplus material, restricting the position change of the extrusion die 210 to prevent the extrusion die 210 from moving together with the surplus material. The surplus material cutting device 530 can cut the surplus material to generate a gap on the surplus material for the surplus material peeling arms 540 to latch onto the surplus material and peel it outward, so that the surplus material closely attached to the side of the extrusion die 210 can be separated from the extrusion die 210. At the same time, the surplus material push rod 550 can push the surplus material stuck in the middle of the extrusion die 210. Due to the action of the surplus material cutting device 530 and the surplus material peeling arms 540, the fit between the surplus material and the extrusion die 210 becomes loose. In this way, the surplus material push rod 550 can push the surplus material to separate the surplus material from the extrusion die 210.

[0062] The surplus material cutting device 530 includes a first surplus material extrusion cutting device 531 above the clamping mechanism 520 and a second surplus material extrusion cutting device 532 below the clamping mechanism 520. The first surplus material extrusion cutting device 531 includes a first cutting head 533 that can be lifted and lowered, and the second surplus material extrusion cutting device 532 includes a second cutting head 534 that can be lifted and lowered. The first surplus material extrusion cutting device 531 and the second surplus material extrusion cutting device 532 can simultaneously extrude the surplus material on both the upper and lower sides of the extrusion die 210 through the first cutting head 533 and the second cutting head 534 to cut the surplus material.

[0063] The first surplus material extrusion cutting device 531 includes a first extrusion push cylinder 535. The first extrusion push cylinder 535 drives the first cutting head 533 to press down on the surplus material on the extrusion die 210. The second surplus material extrusion cutting device 532 includes a second extrusion push cylinder 536. The second extrusion push cylinder 536 drives the second cutting head 534 to extrude the surplus material on the extrusion die 210 upward. The first extrusion push cylinder 535 can control the height position of the first cutting head 533, and the second extrusion push cylinder 536 can control the height position of the second cutting head 534. The first extrusion push cylinder 535 and the second extrusion push cylinder 536 are oil cylinders and can generate a great force, so as to be able to push and press the surplus material to make the surplus material undergo compressive deformation and generate a gap with the side of the extrusion die 210. The first surplus material extrusion cutting device 531 and the second surplus material extrusion cutting device 532 can act simultaneously to extrude the surplus material, reducing the force transmitted from the surplus material to the extrusion die 210 and reducing the load on the clamping mechanism 520.

[0064] The lower end of the first cutting head 533 is provided with a tapered extrusion end 537, and the upper end of the second cutting head 534 is provided with a recessed portion 538 corresponding to the extrusion end 537. The extrusion end 537 can generate extremely high pressure on the remaining material during the extrusion process of the remaining material, thereby cutting the remaining material. The second cutting head 534 only has an extrusion effect on the remaining material. The setting of the recessed portion 538 can ensure that the remaining material can be cut into two parts by the extrusion end 537. If the second cutting head 534 is also provided with the same structure as the extrusion end 537, it cannot be guaranteed that the ends of the two extrusion ends 537 can be aligned to cut the remaining material into two parts.

[0065] A plurality of remaining material discharge grooves 560 are provided around the second remaining material extrusion cutting device 532 on the separation seat body 510. The remaining material discharge grooves 560 can guide the transmission of the remaining material after the remaining material is peeled off, avoiding the remaining material remaining on the separation seat body 510 and affecting the position changes of the first remaining material extrusion cutting device 531, the second remaining material extrusion cutting device 532, the remaining material peeling arm 540, and the remaining material push rod 550.

[0066] The separation seat body 510 is further provided with a liftable lifting column 570. The clamping mechanism 520 is connected to the lifting column 570 to move synchronously with the lift. The remaining material peeling arm 540 is connected to the separation seat body 510. The remaining material peeling arm 540 includes a hook-shaped peeling portion 541 for peeling the remaining material. The lifting column 570 can adjust the height position of the clamping mechanism 520, thereby changing the relative position between the extrusion die 210 and the remaining material peeling arm 540, so that the remaining material peeling arm 540 can peel the remaining material downward.

[0067] The remaining material peeling arm 540 is hingedly installed on the separation seat body 510. The separation seat body 510 is further provided with an electric push rod 542 connected to the remaining material peeling arm 540. The electric push rod 542 is rotatably installed on the separation seat body 510. The electric push rod 542 can push the remaining material peeling arm 540 to make the two remaining material peeling arms 540 approach each other or move away from each other, thereby increasing the force exerted by the remaining material peeling arm 540 on the remaining material and improving the peeling efficiency. The two remaining material peeling arms 540 can act simultaneously to make the force acting on the remaining material close to balance, so as to reduce the force received by the clamping mechanism 520.

[0068] The hook-shaped peeling portion 541 extends from the end of the remaining material peeling arm 540. A material pushing portion 543 is formed between the hook-shaped peeling portion 541 and the end of the remaining material peeling arm 540. The action of the electric push rod 542 drives the material pushing portion 543 to push the remaining material towards the axis direction of the extrusion die 210. Under the action of the electric push rod 542, the material pushing portions 543 on the two remaining material peeling arms 540 can squeeze the remaining material inward, creating a gap between the remaining material and the side surface of the extrusion die 210.

[0069] During the waste material peeling process, the waste material peeling arm 540 first squeezes the waste material inward, causing the waste material attached to the side of the extrusion die 210 to gather and increase in thickness, creating a gap between the waste material and the side of the extrusion die 210. After the waste material is cut by the first waste material extrusion cutting device 531 and the second waste material extrusion cutting device 532, the waste material peeling arm 540 then peels the waste material outward.

[0070] The clamping mechanism 520 includes two die clamps 522 with arc-shaped grooves 521, a connecting rod 523 hinged to the die clamps 522, and a lifting cylinder 524 for driving the connecting rod 523. The die clamps 522 are hingedly installed on the separation seat body 510. The lifting cylinder 524 can drive the connecting rod 523 to act, and when the connecting rod 523 acts, it can drive the die clamps 522 to act. The two side die clamps 522 work together to approach or move away from each other to clamp or release the extrusion die 210. The arc-shaped grooves 521 can increase the contact area between the die clamps 522 and the extrusion die 210, improving the stability of the extrusion die 210 when clamped by the die clamps 522.

[0071] The die pushing device 600 includes a pushing seat body 610 and a die pushing ejector rod 620 that can telescopically move horizontally relative to the pushing seat body 610. The die pushing ejector rod 620 is correspondingly arranged with the clamping center of the clamping mechanism 520 for clamping the extrusion die 210. When the die pushing ejector rod 620 extends, it moves towards the waste material separation device 500 to push the extrusion die 210 to move. When the die pushing ejector rod 620 retracts, it resets to move away from the conveyor belt 110 to avoid affecting the conveyance of the extrusion die 210 on the conveyor belt 110.

[0072] The waste material push rod 550 is arranged on the push rod seat body. The push rod seat body is provided with a first electromagnet for adsorbing the sleeve ring 551. The waste material push rod 550 can telescopically move relative to the sleeve ring 551 to push the waste material remaining in the central part of the extrusion die 210. The waste material push rod 550 is also provided with a second electromagnet, which is activated after the waste material peeling is completed, for adsorbing the sleeve ring 551 to make the sleeve ring 551 move synchronously with the waste material push rod 550 to push the extrusion die 210 onto the conveyor belt 110. The first electromagnet can adsorb the sleeve ring 551 to enable the waste material push rod 550 to move relative to the sleeve ring 551. When the second electromagnet is powered on, the first electromagnet is powered off, so that the sleeve ring 551 can be adsorbed on the waste material push rod 550 and move together with the waste material push rod 550, thereby pushing the extrusion die 210 after waste material peeling from the clamping mechanism 520 onto the conveyor belt 110 to convey the extrusion die 210 through the conveyor belt 110.

[0073] The extruder further includes a die transfer device 700. The extrusion die 210 with waste material removed is conveyed from the conveyor belt 110 towards the die seat body 200, and the die transfer device 700 clamps and transports the extrusion die 210 to the die storage table 710 for waiting for assembly.

[0074] The mold storage table 710 is arranged on the side of the clamping device 410. When pushing the extrusion mold 210 onto the mold seat body 200, the mold transfer device 700 clamps the extrusion mold 210 on the mold storage table 710 to the clamping device 410. After the extrusion mold 210 with the remaining material removed is pushed onto the clamping device 410 by the columnar push head 402, the mold transfer device 700 then clamps the extrusion mold 210 to the mold storage table 710. When the extrusion mold 210 with the remaining material on the mold seat body 200 is disassembled, a new extrusion mold 210 needs to be installed on the mold seat body 200 for the next round of extrusion forming. The hook-shaped push head 403 can push the extrusion mold 210 in the direction of the conveyor belt 110. During the mold replacement process, the new extrusion mold 210 is clamped by the mold transfer device 700 to the clamping device 410 and remains stable without tipping under the action of the clamping device 410. Under the push of the hook-shaped push head 403, the extrusion mold 210 is pushed onto the mold seat body 200 to complete the assembly.

[0075] The mold transfer device 700 includes a transfer seat body 720 and a jaw assembly 730 that can translate in the length direction of the conveyor belt. The jaw assembly 730 includes a clamping lifting rod 740 that can lift relative to the transfer seat body 720 and jaws 750 arranged at the end of the clamping lifting rod 740. The jaw assembly 730 can move along the length direction of the conveyor belt to transfer the extrusion mold 210 between the clamping device 410 and the mold storage table. The clamping lifting rod 740 can adjust the height position of the jaws 750 and can lift and transfer the extrusion mold 210 after the jaws 750 clamp the extrusion mold 210.

Those skilled in the art should understand that the present invention includes not only the content described in the drawings and the above specific implementation manner.
