Description

Technical field

[0001] The invention relates to the field of extrusion molding, in particular to an extruder with a residual material automatic stripping function. [Background Technology]

[0002] Copper tubes have a wide range of applications and are currently produced in a variety of ways, such as by direct casting of molten copper or by extruding copper ingots. Extrusion involves the use of extrusion equipment and a die. The extrusion equipment presses the copper ingot toward the die, where it is formed into a rough tube blank. However, some copper may remain in the die after extrusion, rendering the die incapable of forming the tube. This residual copper must be removed before it can be reused. Currently, stripping the remaining material from the die is a manual process, which is time-consuming, inefficient, and prone to damage. [Summary of the invention]

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and propose an extruder with an automatic residual material stripping function.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An extruder with an automatic residual material stripping function includes a machine base, a mold base body is provided on the machine base, an extrusion mold is provided on the mold base body, a residual material separation device for stripping residual material from the extrusion mold is provided on the side of the machine base, an extrusion device and a discharge device are provided on both sides of the mold base body in the axial direction of the extrusion mold on the machine base, the machine base is provided with a mold disassembly device and a conveyor belt, the mold disassembly device removes the extrusion mold from the mold base body and places it on the conveyor belt and conveys the extrusion mold to the residual material separation device via the conveyor belt, a mold pushing device is provided on the side of the residual material separation device for pushing the extrusion mold toward the residual material separation device, and the conveyor belt is located between the residual material separation device and the mold pushing device.

[0006] On the basis of the above scheme, the residual material separation device includes a separation seat body, on which is provided a clamping mechanism for clamping the extrusion mold and a residual material cutting device that moves in the height direction to cut the residual material. Residual material stripping arms for stripping the residual material outward are also provided on both sides of the clamping mechanism. The clamping mechanism is also provided on one side in the axial direction of the extrusion mold with a residual material push rod arranged corresponding to the center of the extrusion mold.

[0007] Based on the above scheme, the mold pushing device includes a pushing seat body and a mold pushing ejector rod that can be extended and retracted in the horizontal direction relative to the pushing seat body. The mold pushing ejector rod is arranged corresponding to the clamping center of the clamping mechanism for clamping the extrusion mold.

[0008] On the basis of the above scheme, the residual material push rod is arranged on the push rod base body, and the push rod base body is provided with a first electromagnet for adsorbing the ring. The residual material push rod can be extended and retracted relative to the ring to push the residual material remaining in the center of the extrusion mold. The residual material push rod is also provided with a second electromagnet, which is started after the residual material stripping is completed, and is used to adsorb the ring so that the ring moves synchronously with the residual material push rod to push the extrusion mold onto the conveyor belt.

[0009] On the basis of the above solution, a mold transfer device is further provided on the side of the conveyor belt, and the mold transfer device is used to move the extrusion mold with the excess material removed out of the conveyor belt.

[0010] On the basis of the above scheme, the separation seat body is also provided with a liftable lifting column, the clamping mechanism is connected to the lifting column to move synchronously with the lifting main body, the residual material stripping arm is connected to the separation seat body, and the residual material stripping arm includes a hook-shaped stripping part for stripping the residual material.

[0011] On the basis of the above solution, the residual material stripping arm is hingedly mounted on the separation seat body, and the separation seat body is further provided with an electric push rod connected to the residual material stripping arm, and the electric push rod is rotatably mounted on the separation seat body.

[0012] Based on the above scheme, the hook-shaped stripping part is extended from the end of the residual material stripping arm, and a pushing part is formed between the hook-shaped stripping part and the end of the residual material stripping arm. The electric push rod drives the pushing part to push the residual material toward the axis of the extrusion die.

[0013] On the basis of the above solution, a plurality of residual material discharge troughs are provided around the clamping mechanism.

[0014] Based on the above solution, a translation device connected to the mold base is provided on the side of the machine base. The translation device is used to translate the mold base after the extrusion process is completed. The mold disassembly equipment disassembles the extrusion mold after the mold base is translated.

[0015] Beneficial effects of the present invention:

[0016] The extruder disclosed in the present invention is such that during the tube extrusion molding process, a copper ingot is placed between an extrusion device and an extrusion die. The extrusion device squeezes the copper ingot toward the extrusion die so that the copper ingot is pressurized and passes through the extrusion die to form a tube blank. The tube blank is then removed from the discharge device. When the stroke of the extrusion device reaches its maximum value, a round of tube extrusion molding is completed. At this time, some copper ingots still remain on the extrusion die. The extruder can cut off the tube material to separate it from the extrusion die. The die disassembly device can disassemble the extrusion die with residual material from the die base, and place the disassembled extrusion die on a conveyor belt, which is then transported to a residual material separation device. After the extrusion die is transported to the residual material separation device, the residual material separation device automatically strips off the residual material. The die pushing device can transport the extrusion die on the conveyor belt toward the residual material separation device, so that the extrusion die with residual material can be moved to the residual material separation device for residual material stripping.

[0017] Furthermore, the excess material separation device includes a separation base, the separation base being provided with a clamping mechanism for clamping the extrusion die and an excess material cutting device movable in a height direction to cut the excess material. Excess material stripping arms are further provided on either side of the clamping mechanism for stripping the excess material outward. The clamping mechanism is further provided with an excess material pusher located on one side of the extrusion die in the axial direction, corresponding to the center of the extrusion die. The clamping mechanism is capable of clamping the extrusion die during the excess material stripping process, limiting the positional movement of the extrusion die to prevent the extrusion die from moving along with the excess material. The excess material cutting device is capable of cutting the excess material, creating a gap in the excess material that the excess material stripping arms can grasp and strip outward, thereby separating excess material tightly attached to the side of the extrusion die from the die. Simultaneously, the excess material pusher is capable of pushing excess material stuck in the middle of the extrusion die. Due to the action of the excess material cutting mechanism and the excess material stripping arms, the fit between the excess material and the extrusion die is loosened, allowing the excess material pusher to push the excess material and separate it from the die.

[0018] Furthermore, the mold pushing device includes a pushing base and a mold pushing ejector pin that is horizontally extendable relative to the pushing base. The mold pushing ejector pin is positioned corresponding to the clamping center of the clamping mechanism for clamping the extrusion die. When the mold pushing ejector pin is extended, it moves toward the excess material separation device to push the extrusion die. When the mold pushing ejector pin is retracted, it returns to its original position, moving away from the conveyor belt and preventing it from interfering with the extrusion die's transport along the conveyor belt.

[0019] Furthermore, the residual material push rod is arranged on a push rod base, and a first electromagnet for adsorbing a collar is provided on the push rod base. The residual material push rod can be extended and retracted relative to the collar to push the residual material remaining in the center of the extrusion die. The residual material push rod is also provided with a second electromagnet, which is activated after the residual material stripping is completed to adsorb the collar so that the collar moves synchronously with the residual material push rod to push the extrusion die onto the conveyor belt. The first electromagnet can adsorb the collar so that the residual material push rod can move relative to the collar. When the second electromagnet is energized, the first electromagnet is de-energized, so that the collar can be adsorbed on the residual material push rod and move with the residual material push rod, thereby pushing the extrusion die after the residual material stripping is completed from the clamping mechanism to the conveyor belt, so that the extrusion die can be transferred via the conveyor belt.

[0020] Furthermore, a mold transfer device is provided on the side of the conveyor belt, which is used to move the extrusion mold after the excess material is removed from the conveyor belt. The mold transfer device can transfer the extrusion mold sent back to the conveyor belt by the excess material push rod so that the extrusion mold can be reused for extrusion molding.

[0021] Furthermore, the separation base is provided with a liftable column. The clamping mechanism is connected to the column to move synchronously with the lift. The residual material stripping arm is connected to the separation base and includes a hook-shaped stripping portion for stripping residual material. The lifting column adjusts the height of the clamping mechanism, thereby changing the relative position between the extrusion die and the residual material stripping arm, allowing the residual material stripping arm to strip the residual material downward.

[0022] Furthermore, the residual material stripping arms are hingedly mounted on the separation base, and the separation base is also provided with an electric push rod connected to the residual material stripping arms, the electric push rod being rotatably mounted on the separation base. The electric push rod can push the residual material stripping arms, causing the two residual material stripping arms to move closer to or further away from each other, thereby increasing the force exerted by the residual material stripping arms on the residual material and improving stripping efficiency. The two residual material stripping arms can operate simultaneously to achieve a nearly balanced force on the residual material, thereby reducing the force acting on the clamping mechanism.

[0023] Furthermore, the hook-shaped stripping portion extends from the end of the residual material stripping arm, and a pushing portion is formed between the hook-shaped stripping portion and the end of the residual material stripping arm. The electric push rod drives the pushing portion to push the residual material toward the axis of the extrusion die. Under the action of the electric push rod, the pushing portions on the two residual material stripping arms can squeeze the residual material inward, creating a gap between the residual material and the side of the extrusion die.

[0024] Furthermore, a plurality of residual material discharge troughs are provided around the clamping mechanism, which can guide the residual material to be transported after being peeled off, thereby preventing the residual material from remaining on the separation base and affecting the movement of the clamping mechanism, the residual material cutting device, the residual material peeling arm and the residual material push rod.

[0025] Furthermore, a translation device connected to the die base is provided on the side of the machine base. The translation device is used to translate the die base after the extrusion process is completed. The die removal device removes the extrusion die after the die base has translated. The translation device can move the die base after an extrusion cycle is completed, removing the extrusion die with excess material from between the extrusion device and the discharge device, thereby avoiding limiting the space for the die removal device to move.

However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0044] When used herein, words such as "exemplary" and "some embodiments" mean "serving as an example, embodiment, or illustration." Any embodiment described as "exemplary" is not necessarily to be construed as superior or preferable to other embodiments. Numerous specific details are provided in the following detailed description to better illustrate the present invention. However, those skilled in the art will appreciate that the present disclosure may be practiced without these specific details.

[0045] Reference Figures 1 to 6 The present invention discloses an extruder with an automatic residual material stripping function, comprising a machine base 100, a mold base body 200 is provided on the machine base 100, an extrusion mold 300 is provided on the mold base body 200, a residual material separation device 600 for stripping residual material from the extrusion mold 300 is provided on the side of the machine base 100, an extrusion device 400 and a discharging device 500 are provided on both sides of the mold base body 200 in the axial direction of the extrusion mold 300 on the machine base 100, the machine base 100 is provided with a mold disassembly device and a conveyor belt 110, the mold disassembly device removes the extrusion mold 300 from the mold base body 200 and places it on the conveyor belt 110 and conveys the extrusion mold 300 to the residual material separation device 600 through the conveyor belt 110, a mold pushing device 700 for pushing the extrusion mold 300 toward the residual material separation device 600 is provided on the side of the residual material separation device 600, and the conveyor belt 110 is located between the residual material separation device 600 and the mold pushing device 700.

[0046] In the extruder disclosed in the present invention, during the tube extrusion molding process, a copper ingot is placed between an extrusion device 400 and an extrusion die 300. The extrusion device 400 squeezes the copper ingot toward the extrusion die 300, causing it to be pressed and pass through the extrusion die 300 to form a tube blank. The tube blank is then removed from the discharge device 500. When the stroke of the extrusion device 400 reaches its maximum value, a round of tube extrusion molding is completed. At this time, some copper ingots may still remain in the extrusion die 300. The extruder can cut the tube to separate it from the extrusion die 300. The die removal device can remove the extrusion die 300 with excess material from the die base 200 and place the removed extrusion die 300 on a conveyor belt 110. The conveyor belt 110 then transports the removed extrusion die 300 to a residual material separation device 600. After the extrusion die 300 is transported to the residual material separation device 600, the residual material separation device 600 automatically removes the excess material. The mold pushing device 700 can convey the extrusion mold 300 located on the conveyor belt 110 toward the residual material separation device 600, so that the extrusion mold 300 with residual material can be moved to the residual material separation device 600 for residual material stripping processing.

[0047] Due to the limited space between the extrusion device 400 and the discharge device 500, a translation device 800 connected to the mold base 200 is provided on the side of the machine base 100. The translation device 800 is used to translate the mold base 200 after the extrusion process is completed. The mold disassembly equipment disassembles the extrusion mold 300 after the mold base 200 is translated. The translation device 800 can move the mold base 200 after one extrusion is completed, and move the extrusion mold 300 with residual material out from between the extrusion device 400 and the discharge device 500 to avoid limited activity space for the mold disassembly equipment.

[0048] The residual material separation device 600 includes a separation base 610, which is equipped with a clamping mechanism 620 for clamping the extrusion die 300 and a residual material cutting device 630 that moves in the height direction to cut the residual material. Residual material stripping arms 640 for stripping the residual material outward are also provided on both sides of the clamping mechanism 620. The clamping mechanism 620 is also equipped with a residual material push rod 650 on one side of the extrusion die 300 in the axial direction, corresponding to the center of the extrusion die 300. The clamping mechanism 620 can clamp the extrusion die 300 during the residual material stripping process, limiting the position of the extrusion die 300 to prevent the extrusion die 300 from moving along with the residual material. The residual material cutting device 630 can cut the residual material, creating a gap on the residual material for the residual material stripping arm 640 to grasp the residual material and strip the residual material outward, so that the residual material tightly attached to the side of the extrusion mold 300 can be separated from the extrusion mold 300. At the same time, the residual material push rod 650 can push the residual material stuck in the middle of the extrusion mold 300. Due to the action of the residual material cutting device 630 and the residual material stripping arm 640, the fit between the residual material and the extrusion mold 300 is loosened, so that the residual material push rod 650 can push the residual material and separate the residual material from the extrusion mold 300.

[0049] The waste material cutting device 630 includes a first waste material extrusion and cutting device 631 above the clamping mechanism 620 and a second waste material extrusion and cutting device 632 below the clamping mechanism 620. The first waste material extrusion and cutting device 631 includes a first cutting head 633 that can be raised and lowered, and the second waste material extrusion and cutting device 632 includes a second cutting head 634 that can be raised and lowered. The first waste material extrusion and cutting device 631 and the second waste material extrusion and cutting device 632 can extrude the waste material on the upper and lower sides of the extrusion mold 300 at the same time through the first cutting head 633 and the second cutting head 634 so that the waste material is cut.

[0050] The first residual material extrusion and cutting device 631 includes a first extrusion push cylinder 635, which drives the first cutting head 633 to press downward on the residual material on the extrusion die 300. The second residual material extrusion and cutting device 632 includes a second extrusion push cylinder 636, which drives the second cutting head 634 to extrude the residual material on the extrusion die 300. The first extrusion push cylinder 635 controls the height of the first cutting head 633, while the second extrusion push cylinder 636 controls the height of the second cutting head 634. The first and second extrusion push cylinders 635 and 636 are hydraulic cylinders capable of generating significant force, thereby compressing the residual material, causing it to deform and create a gap between it and the side of the extrusion die 300. The first and second residual material extrusion and cutting devices 631 and 632 operate simultaneously to extrude the residual material, reducing the force applied to the extrusion die 300 and the load on the clamping mechanism 620.

[0051] The lower end of the first cutting head 633 is provided with a tapered extrusion end 637, and the upper end of the second cutting head 634 is provided with a recessed portion 638 corresponding to the extrusion end 637. The extrusion end 637 can generate a great deal of pressure on the residual material during the extrusion process, thereby cutting the residual material. The second cutting head 634 only has an extrusion effect on the residual material. The provision of the recessed portion 638 ensures that the residual material can be cut into two parts by the extrusion end 637. If the second cutting head 634 also has the same structure as the extrusion end 637, it cannot be guaranteed that the ends of the two extrusion ends 637 will align to cut the residual material into two parts.

[0052] The separation base 610 is provided with a plurality of waste material discharge chutes 660 around the second waste material extrusion and cutting device 632. The waste material discharge chutes 660 guide the waste material after it is stripped, preventing it from remaining on the separation base 610 and affecting the position changes of the first waste material extrusion and cutting device 631, the second waste material extrusion and cutting device 632, the waste material stripping arm 640, and the waste material push rod 650.

[0053] The separator body 610 is also equipped with a lift column 670 that can be raised and lowered. The clamping mechanism 620 is connected to the lift column 670 to move synchronously with the lift column. A residual material stripping arm 640 is also connected to the separator body 610. The residual material stripping arm 640 includes a hook-shaped stripping portion 641 for stripping residual material. The lift column 670 can adjust the height of the clamping mechanism 620, thereby changing the relative position between the extrusion die 300 and the residual material stripping arm 640, allowing the residual material stripping arm 640 to strip the residual material downward.

[0054] The residual material stripping arms 640 are hingedly mounted on the separation base 610. The separation base 610 is also provided with an electric push rod 642 connected to the residual material stripping arms 640. The electric push rod 642 is rotatably mounted on the separation base 610. The electric push rod 642 can push the residual material stripping arms 640, causing the two residual material stripping arms 640 to move closer to or further away from each other, thereby increasing the force exerted on the residual material by the residual material stripping arms 640 and improving stripping efficiency. The two residual material stripping arms 640 can operate simultaneously to achieve a nearly balanced force on the residual material, thereby reducing the force acting on the clamping mechanism 620.

[0055] A hook-shaped stripping portion 641 extends from the end of the residual material stripping arm 640. A pusher portion 643 is formed between the hook-shaped stripping portion 641 and the end of the residual material stripping arm 640. The electric push rod 642 drives the pusher portion 643 to push the residual material toward the axis of the extrusion die 300. Under the action of the electric push rod 642, the pushers 643 on the two residual material stripping arms 640 can squeeze the residual material inward, creating a gap between the residual material and the side of the extrusion die 300.

[0056] During the residual material stripping process, the residual material stripping arm 640 first squeezes the residual material inward, causing the residual material attached to the side of the extrusion mold 300 to shrink and increase the thickness, creating a gap between the residual material and the side of the extrusion mold 300. After the residual material is cut by the first residual material extrusion and cutting device 631 and the second residual material extrusion and cutting device 632, the residual material stripping arm 640 strips the residual material outward.

[0057] The clamping mechanism 620 includes two mold clamps 622 with arcuate grooves 621, a connecting rod 623 hingedly connected to the mold clamps 622, and a lifting cylinder 624 that drives the connecting rod 623. The mold clamps 622 are hingedly mounted on the separation base 610. The lifting cylinder 624 can drive the connecting rod 623 to move, and when the connecting rod 623 moves, the mold clamps 622 can move. The mold clamps 622 on both sides work together to move closer to or away from each other to clamp or release the extrusion die 300. The arcuate grooves 621 can increase the contact area between the mold clamps 622 and the extrusion die 300, thereby improving the stability of the extrusion die 300 when clamped by the mold clamps 622.

[0058] The mold pushing device 700 includes a pushing base 710 and a mold pushing pin 720 that can be extended and retracted horizontally relative to the pushing base 710. The mold pushing pin 720 is positioned corresponding to the clamping center of the clamping mechanism 620 for clamping the extrusion die 300. When extended, the mold pushing pin 720 moves toward the residual material separation device 600 to push the extrusion die 300. When retracted, the mold pushing pin 720 returns to its original position, removing it from the conveyor belt 110 and preventing it from interfering with the extrusion die 300's movement along the conveyor belt 110.

[0059] The residual material push rod 650 is disposed on a push rod base. A first electromagnet is provided on the push rod base for attracting a collar 651. The residual material push rod 650 can extend and retract relative to the collar 651 to push the residual material remaining in the center of the extrusion die 300. A second electromagnet is also provided on the residual material push rod 650. After the residual material is stripped, the second electromagnet is activated to attract the collar 651, causing the collar 651 to move synchronously with the residual material push rod 650 to push the extrusion die 300 onto the conveyor belt 110. The first electromagnet attracts the collar 651, allowing the residual material push rod 650 to move relative to the collar 651. When the second electromagnet is energized, the first electromagnet is de-energized, allowing the collar 651 to be attracted to the residual material push rod 650 and move with the residual material push rod 650, thereby pushing the extrusion die 300, after the residual material is stripped, from the clamping mechanism 620 onto the conveyor belt 110, for transfer of the extrusion die 300 via the conveyor belt 110.

[0060] A mold transfer device is also provided on the side of the conveyor belt 110, and the mold transfer device is used to move the extrusion mold 300 with the excess material removed out of the conveyor belt 110. The mold transfer device can transfer the extrusion mold 300 sent back to the conveyor belt 110 by the excess material push rod 650 so that the extrusion mold 300 can be reused for extrusion molding.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the drawings and the above specific embodiments.
