Description

[Technical field]

[0001] The invention relates to the field of extrusion molding, in particular to an extruder with an automatic mold disassembly function. [Background technology]

[0002] Copper tubes have a wide range of application scenarios. Currently, there are many ways to make copper tubes, such as directly casting them with molten copper or extruding copper ingots. In the extrusion molding method, extrusion equipment and extrusion dies are used. The extrusion equipment extrude the copper ingots toward the extrusion die. After passing through the extrusion die, the copper ingots 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. The copper materials remaining on the extrusion die need to be removed before they can be used again. Therefore, the extrusion die needs to be replaced, but the replacement of the extrusion die is more complicated and time-consuming, which will affect the production progress of the tube.

[0014] Beneficial effects of the present invention:

[0015] The extruder disclosed in the present invention has the following characteristics: during the tube material extrusion molding process, the copper ingot is placed between the extrusion device and the extrusion die, the extrusion device extrudes the copper ingot in the direction of the extrusion die so that the copper ingot is pressed and passes through the extrusion die to form a tube material blank, the tube material blank is moved out from the discharging device, and when the stroke of the extrusion device reaches the maximum value, one round of tube material extrusion molding is completed, at this time, some copper ingots are still left on the extrusion die, the extruder can cut off the tube material to separate the tube material from the extrusion die, the translation device can move the die base after one extrusion is completed, and move the extrusion die with the remaining material out from between the extrusion device and the discharging device, the die disassembly equipment can disassemble the extrusion die with the remaining material from the die base, and place the disassembled extrusion die on the conveyor belt, which is transferred outward by the conveyor belt, so that the extrusion die can be away from the extrusion device, so that even if the extrusion die is moved away from the conveyor belt by manual operation, the safety factor can be greatly improved.

[0016] Furthermore, the die base is provided with a stopper, which stops the extrusion die in the direction in which the extrusion device extrudes the raw material. The stopper can stop the extrusion die to ensure that the extrusion die will not be pushed by the extrusion device and change position during the extrusion molding process.

[0017] Furthermore, the die disassembly device includes a toggle device, which pushes the extrusion die to remove the extrusion die from the die base. The limiter cannot block the movement of the extrusion die toward the extrusion device, and the toggle device can push the extrusion die to move relative to the die base, thereby removing the extrusion die from the die base.

[0018] Furthermore, the conveyor belt is arranged below the mold base, and the mold disassembly device further comprises a clamping device for clamping the extrusion mold, the clamping device is arranged between the shifting device and the translation device, and the shifting device pushes the extrusion mold toward the clamping device so that the extrusion mold is translated onto the clamping device. Since the conveyor belt is located below the mold base, the shifting device cannot directly push the extrusion mold from the mold base onto the conveyor belt, and by providing the clamping device, the shifting device can transfer the extrusion mold to the clamping device.

[0019] Furthermore, the toggle device includes a retractable toggle rod, the toggle rod has a columnar pusher and a hook-shaped pusher, the columnar pusher is used to push the extrusion die on the die seat toward the clamping device, and the hook-shaped pusher is arranged below the columnar pusher and is used to push the extrusion die on the clamping device toward the conveyor belt. The toggle rod can perform telescopic movement to push the extrusion die. When the toggle rod is extended, the columnar pusher can push the extrusion die to leave the die seat, and when the toggle rod is retracted, the hook-shaped pusher can push the extrusion die to leave the clamping device and move it to the conveyor belt, thereby conveying the extrusion die through the conveyor belt.

[0020] Furthermore, the toggle device further comprises a toggle seat body, the toggle rod is rotatably arranged on the toggle seat body, the toggle seat body is provided with a push rod hinged to the toggle rod, the push rod can be extended and retracted relative to the toggle rod to drive the toggle rod to rotate relative to the toggle seat body. During the extension and retraction process, the push rod can drive the wave lever to flip relative to the toggle seat body, thereby avoiding the mold seat body that is translated above the conveyor belt, and allowing the hook-shaped push head to avoid the extrusion mold located on the clamping device.

[0021] Further, the clamping device includes a clamping seat body, a first clamping arm and a second clamping arm. The first clamping arm is fixedly connected to the clamping seat body, and the second clamping arm is rotatably connected to the clamping seat body. At least three clamping supports are provided on the first clamping arm and the second clamping arm and are distributed in the circumferential direction of the extrusion die. A driven roller is rotatably installed on the clamping support. The second clamping arm can be flipped relative to the first clamping arm to adjust the distance therebetween, so as to clamp the extrusion die and maintain the stability of the extrusion die. By clamping and supporting the extrusion die with at least three clamping supports, the stability of the extrusion die during movement can be maintained, and the extrusion die can be prevented from tipping over, which is not convenient for transporting the extrusion die out of the conveyor belt. The driven roller can be driven to rotate during the translation of the extrusion die, which can reduce the friction between the extrusion die and the clamping support and improve the smoothness of the extrusion die during movement.

[0022] Further, the translation device includes a translation push rod and a translation machine base. The translation push rod is arranged on the translation machine base and is connected to the die seat body. The translation push rod expands and contracts relative to the translation machine base to drive the die seat body to perform a translation movement. The translation push rod can perform an expansion and contraction movement to synchronously move the die seat body during the movement. By setting the stroke of the translation push rod, the displacement distance of the die seat body can be adjusted, so that the extrusion die can be aligned with the extrusion device and the discharging device. The translation machine base can maintain the position of the translation push rod, so that the translation push rod can move in the horizontal direction.

[0023] Further, the extrusion device includes a hydraulic cylinder and an extrusion column driven by the hydraulic cylinder. The hydraulic cylinder can generate a great force, thereby driving the extrusion column to move to extrude the copper ingot to produce a tube blank.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

Detailed implementation manners

[0041] The technical solutions of the embodiments of the present invention will be explained and described 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, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0042] Words such as "exemplary" and "some embodiments" that appear below mean "used as an example, embodiment or illustrative", and any embodiment described as "exemplary" does not have to be interpreted as superior to or better than other embodiments. In order to better illustrate the present invention, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present disclosure can also be implemented without some specific details.

[0043] Refer to Figures 1 to 6, the present invention discloses an extruder with an automatic die disassembly function, including a machine base 100, a die seat body 200 is provided on the machine base 100, an extrusion die 300 is provided on the die seat body 200, an extrusion device 400 and a discharge device 500 are provided on both sides of the die seat body 200 in the axial direction of the extrusion die 300 on the machine base 100, a translation device 600 for connecting the die seat body 200 is provided on the side of the machine base 100, and the translation device 600 is used to translate the die seat body 200 after the extrusion process ends. The machine base 100 is provided with a die disassembly device and a conveyor belt 110. The die disassembly device disassembles the extrusion die 300 from the die seat body 200 and places it on the conveyor belt 110, and conveys the extrusion die 300 outward through the conveyor belt 110.

[0044] In the extruder disclosed by the present invention, during the tube blank extrusion forming process, the copper ingot is placed between the extrusion device 400 and the extrusion die 300. The extrusion device 400 extrudes the copper ingot towards the extrusion die 300, so that the copper ingot is compressed and passes through the extrusion die 300 to form a tube blank rough. The tube blank rough is removed from the discharge device 500. When the stroke of the extrusion device 400 reaches the maximum value, one round of tube blank extrusion forming ends. At this time, there is still part of the copper ingot remaining on the extrusion die 300. The extruder can cut off the tube blank to separate the tube blank from the extrusion die 300. The translation device 600 can move the die seat body 200 after one extrusion, and move the extrusion die 300 with remaining material out from between the extrusion device 400 and the discharge device 500. The die disassembly device can disassemble the extrusion die 300 with remaining material from the die seat body 200, and place the disassembled extrusion die 300 on the conveyor belt 110, which is transmitted outward by the conveyor belt 110, so that the extrusion die 300 can be far away from the extrusion device 400. In this way, even if the extrusion die 300 is moved away from the conveyor belt 110 manually, the safety factor can be greatly improved.

[0045] The extruder further includes a remaining material stripping device. The conveyor belt conveys the extrusion die 300 with remaining material to the remaining material stripping device to remove the remaining material on the extrusion die 300 through the remaining material stripping device.

[0046] A limiting member is further provided on the die seat body 200. The limiting member stops the extrusion die 300 in the direction of the extrusion device 400 extruding the raw material. The limiting member can stop the extrusion die 300 to ensure that the extrusion die 300 will not be pushed by the extrusion device 400 and cause a position change during the extrusion forming process.

[0047] After the translation device 600 moves the die holder 200, the extrusion die 300 needs to be replaced, and the replacement position is relatively close to the extrusion device 400 and the discharging device 500. To reduce potential safety hazards, the die disassembling device includes a toggling device 700 provided on the side of the extrusion device 400. The toggling device 700 acts to push the extrusion die 300 to disassemble the extrusion die 300 from the die holder 200. The toggling device 700 is used to disassemble the extrusion die 300 from the die holder 200. In this way, the operator does not need to manually disassemble the extrusion die 300, thus liberating human labor and reducing potential safety hazards. The limiting member cannot block the movement of the extrusion die 300 in the direction towards the extrusion device 400. The toggling device 700 can push the extrusion die 300 to move the extrusion die 300 relative to the die holder 200, thereby removing the extrusion die 300 from the die holder 200.

[0048] The conveyor belt 110 is arranged below the die holder 200. The die disassembling device further includes a clamping device 800 for clamping the extrusion die 300. The clamping device 800 is arranged between the toggling device 700 and the translation device 600. The toggling device 700 pushes the extrusion die 300 towards the clamping device 800, causing the extrusion die 300 to translate onto the clamping device 800. Since the conveyor belt 110 is located below the die holder 200, the toggling device 700 cannot directly push the extrusion die 300 from the die holder 200 onto the conveyor belt 110. By providing the clamping device 800, the toggling device 700 can transfer the extrusion die 300 to the clamping device 800.

[0049] The toggling device 700 includes a telescopic toggling rod 710. The toggling rod 710 has a columnar push head 720 and a hook-shaped push head 730. The columnar push head 720 is used to push the extrusion die 300 on the die holder 200 towards the clamping device 800. The hook-shaped push head 730 is arranged below the columnar push head 720 and is used to push the extrusion die 300 on the clamping device 800 towards the conveyor belt 110. The toggling rod 710 can perform telescopic movement to be able to push the extrusion die 300. When the toggling rod 710 extends, it can push the extrusion die 300 through the columnar push head 720 to make the extrusion die 300 leave the die holder 200. When the toggling rod 710 retracts, it can push the extrusion die 300 through the hook-shaped push head 730 to make the extrusion die 300 leave the clamping device 800 and move onto the conveyor belt 110, thereby conveying the extrusion die 300 through the conveyor belt 110.

[0050] The toggle device 700 further includes a toggle seat 740, on which the toggle rod 710 is rotatably disposed, and on which the toggle seat 740 is disposed a push rod 750 hinged to the toggle rod 710, and the push rod 750 can be extended and retracted relative to the toggle rod 710 to drive the toggle rod 710 to rotate relative to the toggle seat 740. During the extension and retraction process, the push rod 750 can drive the wave lever to flip relative to the toggle seat 740, thereby avoiding the mold seat 200 that is translated to above the conveyor belt 110, and allowing the hook-shaped push head 730 to avoid the extrusion mold 300 located on the clamping device 800.

[0051] In order to prevent the extrusion die 300 from tipping over and enable the residual material stripping device to smoothly fix the extrusion die 300 to remove the residual material, it is necessary to ensure that the extrusion die 300 moves in a translational motion from the die base 200 to the clamping device 800 and from the clamping device 800 to the conveyor belt 110. The clamping device 800 includes a clamping base 810, a first clamping arm 820 and a second clamping arm 830. The first clamping arm 820 is fixedly connected to the clamping base 810, and the second clamping arm 830 is rotatably connected to the clamping base 810. The first clamping arm 820 and the second clamping arm 830 are provided with at least three clamping supports 840 distributed in the circumferential direction of the extrusion die 300, and the clamping supports 840 are rotatably mounted with driven rollers 850. The second clamping arm 830 can be flipped relative to the first clamping arm 820 to adjust the distance between the two to clamp the extrusion mold 300 and maintain the stability of the extrusion mold 300. The extrusion mold 300 is clamped and supported by at least three clamping supports 840, which can maintain the stability of the extrusion mold 300 during movement and prevent the extrusion mold 300 from tipping over, making it inconvenient to transport the extrusion mold 300 outward from the conveyor belt 110. The driven roller 850 can be driven to rotate during the translation of the extrusion mold 300, which can reduce the friction between the extrusion mold 300 and the clamping support 840 and improve the smoothness of the movement of the extrusion mold 300.

[0052] A loading platform 120 for carrying the extrusion die 300 is also provided on the conveyor belt 110 .

[0053] The translation device 600 includes a translation push rod 610 and a translation base 620. The translation push rod 610 is arranged on the translation base 620 and is connected to the mold base body 200. The translation push rod 610 expands and contracts relative to the translation base 620 to drive the mold base body 200 to move translationally. The translation push rod 610 can perform expansion and contraction movements to drive the mold base body 200 to move synchronously during the movement. By setting the stroke of the translation push rod 610, the displacement distance of the mold base body 200 can be adjusted so that the extrusion mold 300 can be aligned with the extrusion device 400 and the discharging device 500. The translation base 620 can maintain the position of the translation push rod 610 so that the translation push rod 610 can move in the horizontal direction. A device for providing power to the translation push rod 610 is also provided on the side of the base 100 to drive the translation push rod 610 to perform expansion and contraction movements. The expansion and contraction movement of the translation push rod 610 means that the translation push rod 610 itself can expand and contract and change its own length; or, the translation push rod 610 can move relative to the translation base 620.

[0054] The extrusion device 400 includes a hydraulic cylinder 410 and an extrusion column 420 driven by the hydraulic cylinder 410. The hydraulic cylinder 410 can generate a great force to drive the extrusion column 420 to move to extrude the copper ingot to produce the tube blank. The discharging device 500 includes a discharging port 510 and a sawing device arranged beside the discharging port 510. The sawing device cuts the tube material after the tube material is formed to a certain length, or cuts the tube material when the copper ingot cannot be extruded continuously and the extrusion device 400 needs to be reset.

[0055] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. 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. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
