Description

Technical Field

[0001] The present invention relates to the field of extrusion molding, and particularly to a device for separating surplus materials from an extrusion die and 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, and the copper ingot can be formed into a rough tube blank after passing through the extrusion die. Some copper materials will remain on the extrusion die after extrusion. At this time, the extrusion die cannot be used to make tubes, and the copper materials remaining on the extrusion die need to be removed before it can be used again. Currently, the peeling of surplus materials on the extrusion die is all manual operation, which takes a long time, has low efficiency, and is prone to damage the extrusion die during the peeling process.

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 a device for separating surplus materials from an extrusion die, which solves the problem of low efficiency of manual peeling of surplus materials.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] A device for separating surplus materials from an extrusion die, including a separation seat body. A clamping mechanism for clamping the extrusion die is provided on the separation seat body. Above the clamping mechanism, there is a first surplus material extrusion and cutting device. Below the clamping mechanism, there is a second surplus material extrusion and cutting device. The first surplus material extrusion and cutting device includes a first cutting head that can be lifted and lowered. The second surplus material extrusion and cutting device includes a second cutting head that can be lifted and lowered. Surplus material peeling arms are also provided on both sides of the clamping mechanism, and the surplus material peeling arms are used to peel the surplus materials outwards. On one side of the clamping mechanism in the axial direction of the extrusion die, there is also a surplus material push rod corresponding to the center of the extrusion die.

[0006] Based on the above solution, the first surplus material extrusion and cutting device includes a first extrusion push cylinder, and the first extrusion push cylinder drives the first cutting head to press down on the surplus materials on the extrusion die. The second surplus material extrusion and cutting device includes a second extrusion push cylinder, and the second extrusion push cylinder drives the second cutting head to extrude the surplus materials on the extrusion die upwards.

[0007] Based on the above solution, the lower end of the first cutting head is provided with a tapered extrusion end, and the upper end of the second cutting head is provided with a recess corresponding to the extrusion end.

[0008] Based on the above solution, a plurality of surplus material discharge grooves are provided on the separation seat body around the second surplus material extrusion and cutting device.

[0009] Based on the above solution, a lift column that can be lifted is further provided on the separation seat body. The clamping mechanism is connected to the lift column to move synchronously with the lift column. The residue stripping arm is connected to the separation seat body, and the residue stripping arm includes a hook-shaped stripping portion for stripping the residue.

[0010] Based on the above solution, the residue stripping arm is hingedly installed on the separation seat body. An electric push rod for connecting the residue stripping arm is further provided on the separation seat body, and the electric push rod is rotatably installed on the separation seat body.

[0011] Based on the above solution, the hook-shaped stripping portion extends from the end of the residue stripping arm. A pushing portion is formed between the hook-shaped stripping portion and the end of the residue stripping arm. The electric push rod acts to drive the pushing portion to push the residue towards the axis of the extrusion die.

[0012] Based on the above solution, the clamping mechanism includes two die clamps with arc-shaped grooves, a connecting rod hinged to the die clamps, and a lifting cylinder for driving the connecting rod. The die clamps are hingedly installed on the separation seat body.

[0013] An extruder includes a machine base. A residue separation device for an extrusion die disclosed in any of the above technical solutions is provided on the side of the machine base. A die seat body is provided on the machine base, and the extrusion die is provided on the die seat body. An extrusion device and a discharging device are provided on both sides of the die seat body on the machine base in the axial direction of the extrusion die. The machine base is provided with a die dismounting device and a conveyor belt. The die dismounting device disassembles the extrusion die from the die seat body and places it on the conveyor belt, and conveys the extrusion die to the residue separation device for the extrusion die through the conveyor belt.

[0014] The beneficial effects of the present invention:

[0015] The present invention discloses a device for separating the surplus material of an extrusion die. The clamping mechanism can clamp the extrusion die during the process of peeling off the surplus material, restricting the position change of the extrusion die to prevent the extrusion die from moving together with the surplus material. The first surplus material extrusion and cutting device and the second surplus material extrusion and cutting device can simultaneously extrude the surplus material on the upper and lower sides of the extrusion die through the first cutting head and the second cutting head, so that the surplus material is cut. After the surplus material is cut, the surplus material peeling arms on both sides of the clamping mechanism peel off the surplus material outwards, so that the surplus material tightly attached to the side of the extrusion die can be separated from the extrusion die. At the same time, the surplus material push rod can push the surplus material stuck in the middle of the extrusion die. Due to the action of the first surplus material extrusion and cutting device, the second surplus material extrusion and cutting device and the surplus material peeling arms, the fit between the surplus material and the extrusion die becomes loose. In this way, the surplus material push rod can push the surplus material to separate it from the extrusion die. The device for separating the surplus material of the extrusion die can liberate manpower, and has a high surplus material peeling efficiency. The positions of the first surplus material extrusion and cutting device, the second surplus material extrusion and cutting device, the surplus material peeling arms and the surplus material push rod can be controlled by programs and sensors, which can reduce the damage to the extrusion die during the surplus material peeling process.

[0016] Further, the first surplus material extrusion and cutting device includes a first extrusion push cylinder, and the first extrusion push cylinder drives the first cutting head to press down on the surplus material on the extrusion die. The second surplus material extrusion and cutting device includes a second extrusion push cylinder, and the second extrusion push cylinder drives the second cutting head to extrude the surplus material on the extrusion die upwards. The first extrusion push cylinder can control the height position of the first cutting head, and the second extrusion push cylinder can control the height position of the second cutting head. The first extrusion push cylinder and the second extrusion push cylinder are hydraulic cylinders, which can generate great force, so as 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. The first surplus material extrusion and cutting device and the second surplus material extrusion and cutting device can act simultaneously to extrude the surplus material, reducing the force transmitted to the extrusion die by the surplus material and reducing the load of the clamping mechanism.

[0017] Further, the lower end of the first cutting head is provided with a tapered extrusion end, and the upper end of the second cutting head is provided with a recess corresponding to the extrusion end. The extrusion end can generate great pressure on the surplus material during the process of extruding the surplus material, so as to cut the surplus material. The second cutting head only has an extrusion effect on the surplus material. The setting of the recess can ensure that the surplus material can be cut into two parts by the extrusion end. If the second cutting head is also provided with the same structure as the extrusion end, it cannot be guaranteed that the ends of the two extrusion ends can be aligned to cut the surplus material into two parts.

[0018] Further, a plurality of surplus material discharging grooves are provided around the second surplus material extrusion cutting device on the separating seat body. The surplus material discharging grooves can guide the conveyance of the surplus material after the surplus material is peeled off, preventing the surplus material from remaining on the separating seat body and affecting the position changes of the first surplus material extrusion cutting device, the second surplus material extrusion cutting device, the surplus material peeling arm, and the surplus material push rod.

[0019] Further, a lift column that can be lifted is also provided on the separating seat body. The clamping mechanism is connected to the lift column to move synchronously with the lift column. The surplus material peeling arm is connected to the separating seat body. The surplus material peeling arm includes a hook-shaped material peeling portion for peeling the surplus material. The lift column can adjust the height position of the clamping mechanism, thereby changing the relative position between the extrusion die and the surplus material peeling arm, enabling the surplus material peeling arm to peel the surplus material downward.

[0020] Further, the surplus material peeling arm is hingedly installed on the separating seat body. An electric push rod connecting the surplus material peeling arm is also provided on the separating seat body. The electric push rod is rotatably installed on the separating seat body. The electric push rod can push the surplus material peeling arm, causing the two surplus material peeling arms to approach or move away from each other, thereby increasing the force exerted by the surplus material peeling arm on the surplus material and improving the peeling efficiency. The two surplus material peeling arms can act simultaneously to make the force acting on the surplus material approach balance, reducing the force exerted on the clamping mechanism.

[0021] Further, the hook-shaped material peeling portion extends from the end of the surplus material peeling arm. A material pushing portion is formed between the hook-shaped material peeling portion and the end of the surplus material peeling arm. The electric push rod acts to drive the material pushing portion to push the surplus material towards the axis of the extrusion die. Under the action of the electric push rod, the material pushing portions on the two surplus material peeling arms can squeeze the surplus material inward, creating a gap between the surplus material and the side surface of the extrusion die.

[0022] Further, the clamping mechanism includes two die clamps with arc-shaped grooves, a connecting rod hinged to the die clamps, and a lifting cylinder for driving the connecting rod. The die clamps are hingedly installed on the separating seat body. The lifting cylinder can drive the connecting rod to act. When the connecting rod acts, it can drive the die clamps to act. The two die clamps on both sides work together to approach or move away from each other to clamp or release the extrusion die. The arc-shaped grooves can increase the contact area between the die clamps and the extrusion die, improving the stability when the extrusion die is clamped by the die clamps.

[0023] The present invention also discloses an extruder, on which the extruded die residue separation device disclosed in any of the above technical solutions is used. During the process of tube material extrusion forming, a copper ingot is placed between the extrusion device and the extrusion die. The extrusion device extrudes the copper ingot towards the extrusion die, causing the copper ingot to be pressed and pass through the extrusion die to form a rough tube blank. The rough tube blank is removed from the discharging device. When the stroke of the extrusion device reaches the maximum value, one round of tube material extrusion forming ends. At this time, there is still part of the copper ingot remaining on the extrusion die. The extruder can cut the tube material to separate the tube material from the extrusion die. The die disassembly device can disassemble the extrusion die with residue from the die seat body and place the disassembled extrusion die on the conveyor belt, which conveys it to the extrusion die residue separation device. When the extrusion die is conveyed to the extrusion die residue separation device, the residue is automatically stripped by the extrusion die residue separation device. Thus, during the use of the extruder, the user does not need to manually transfer the extrusion die with residue.

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

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.

[0040] 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 or better than other embodiments. In order to better illustrate the present invention, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present disclosure can also be implemented without some specific details.

[0041] Refer to Figure 1 And Figure 2 As shown in and, the present invention discloses a device for separating remnants of an extrusion die, including a separating seat body 100. A clamping mechanism 200 for clamping an extrusion die 300 is provided on the separating seat body 100. Above the clamping mechanism 200, there is a first remnant extrusion and cutting device 400. Below the clamping mechanism 200, there is a second remnant extrusion and cutting device 410. The first remnant extrusion and cutting device 400 includes a liftable first cutting head 401. The second remnant extrusion and cutting device 410 includes a liftable second cutting head 411. Remnant stripping arms 500 are further provided on both sides of the clamping mechanism 200. The remnant stripping arms 500 are used to strip remnants outwards. On one side of the clamping mechanism 200 in the axial direction of the extrusion die 300, there is also a remnant push rod arranged corresponding to the center of the extrusion die 300.

[0042] The clamping mechanism 200 can clamp and extrude the extrusion die 300 during the process of stripping the surplus material, restricting the position change of the extrusion die 300 to prevent the extrusion die 300 from moving together with the surplus material. The first surplus material extrusion and cutting device 400 and the second surplus material extrusion and cutting device 410 can simultaneously extrude the surplus material on the upper and lower sides of the extrusion die 300 through the first cutting head 401 and the second cutting head 411, so that the surplus material is cut. After the surplus material is cut, the surplus material stripping arms 500 on both sides of the clamping mechanism 200 strip the surplus material outwards, so that the surplus material closely attached to the side surface of the extrusion die 300 can be separated from the extrusion die 300. At the same time, the surplus material push rod can push the surplus material stuck in the middle of the extrusion die 300. Due to the action of the first surplus material extrusion and cutting device 400, the second surplus material extrusion and cutting device 410 and the surplus material stripping arms 500, the fit between the surplus material and the extrusion die 300 becomes loose. In this way, the surplus material push rod can push the surplus material to separate the surplus material from the extrusion die 300. Through the surplus material separation device of the extrusion die 300, manual labor can be liberated, and the surplus material stripping efficiency is high. The positions of the first surplus material extrusion and cutting device 400, the second surplus material extrusion and cutting device 410, the surplus material stripping arms 500, and the surplus material push rod can be controlled by programs and sensors, which can reduce the damage to the extrusion die 300 during the surplus material stripping process.

[0043] The first surplus material extrusion and cutting device 400 includes a first extrusion push cylinder 402. The first extrusion push cylinder 402 drives the first cutting head 401 to press down on the surplus material on the extrusion die 300. The second surplus material extrusion and cutting device 410 includes a second extrusion push cylinder 412. The second extrusion push cylinder 412 drives the second cutting head 411 to extrude the surplus material on the extrusion die 300 upwards. The first extrusion push cylinder 402 can control the height position of the first cutting head 401, and the second extrusion push cylinder 412 can control the height position of the second cutting head 411. The first extrusion push cylinder 402 and the second extrusion push cylinder 412 are hydraulic cylinders, which can generate great force, so as to be able to push and press the surplus material to make the surplus material deformed under pressure and generate a gap with the side surface of the extrusion die 300. The first surplus material extrusion and cutting device 400 and the second surplus material extrusion and cutting device 410 can act simultaneously to extrude the surplus material, reducing the force transmitted to the extrusion die 300 by the surplus material and reducing the load of the clamping mechanism 200.

[0044] The lower end of the first cutting head 401 is provided with a tapered extrusion end 403, and the upper end of the second cutting head 411 is provided with a recessed part 413 corresponding to the extrusion end 403. The extrusion end 403 can generate great pressure on the surplus material during the process of extruding the surplus material, so as to cut the surplus material. The second cutting head 411 only has an extrusion effect on the surplus material. The setting of the recessed part 413 can ensure that the surplus material can be cut into two parts by the extrusion end 403. If the second cutting head 411 is also provided with the same structure as the extrusion end 403, it cannot be guaranteed that the ends of the two extrusion ends 403 can be aligned to cut the surplus material into two parts.

[0045] A plurality of waste material discharging grooves 600 are provided around the second waste material extrusion cutting device 410 on the separating seat body 100. The waste material discharging grooves 600 can guide the waste material to be conveyed after the waste material is peeled off, avoiding the waste material remaining on the separating seat body 100 and affecting the position changes of the first waste material extrusion cutting device 400, the second waste material extrusion cutting device 410, the waste material peeling arm 500, and the waste material push rod.

[0046] The separating seat body 100 is further provided with a liftable lift column 700. The clamping mechanism 200 is connected to the lift column 700 to move synchronously with the lift. The waste material peeling arm 500 is connected to the separating seat body 100. The waste material peeling arm 500 includes a hook-shaped material peeling portion 510 for peeling the waste material. The lift column 700 can adjust the height position of the clamping mechanism 200, thereby changing the relative position between the extrusion die 300 and the waste material peeling arm 500, so that the waste material peeling arm 500 can peel the waste material downward.

[0047] The waste material peeling arm 500 is hingedly installed on the separating seat body 100. The separating seat body 100 is further provided with an electric push rod 520 connected to the waste material peeling arm 500. The electric push rod 520 is rotationally installed on the separating seat body 100. The electric push rod 520 can push the waste material peeling arm 500, so that the two waste material peeling arms 500 approach each other or move away from each other, thereby increasing the acting force exerted by the waste material peeling arm 500 on the waste material and improving the peeling efficiency. The two waste material peeling arms 500 can act simultaneously to make the acting force on the waste material close to balance, so as to reduce the acting force received by the clamping mechanism 200.

[0048] The hook-shaped material peeling portion 510 extends from the end of the waste material peeling arm 500. A material pushing portion 530 is formed between the hook-shaped material peeling portion 510 and the end of the waste material peeling arm 500. The action of the electric push rod 520 drives the material pushing portion 530 to push the waste material toward the axis of the extrusion die 300. Under the action of the electric push rod 520, the material pushing portions 530 on the two waste material peeling arms 500 can squeeze the waste material inward, creating a gap between the waste material and the side surface of the extrusion die 300.

[0049] During the waste material peeling process, the waste material peeling arm 500 first squeezes the waste material inward, causing the waste material attached to the side surface of the extrusion die 300 to gather and increase in thickness, creating a gap between the waste material and the side surface of the extrusion die 300. After the waste material is cut by the first waste material extrusion cutting device 400 and the second waste material extrusion cutting device 410, the waste material peeling arm 500 then peels the waste material outward.

[0050] The clamping mechanism 200 includes two die clamps 220 with arc-shaped grooves 210, a connecting rod 230 hinged to the die clamps 220, and a lifting cylinder 240 for driving the connecting rod 230. The die clamps 220 are hingedly installed on the separation seat body 100. The lifting cylinder 240 can drive the connecting rod 230 to act. When the connecting rod 230 acts, it can drive the die clamps 220 to act. The two die clamps 220 on both sides work together to approach or move away from each other to clamp or release the extrusion die 300. The arc-shaped grooves 210 can increase the contact area between the die clamps 220 and the extrusion die 300, and improve the stability when the extrusion die 300 is clamped by the die clamps 220.

[0051] Referring Figure 3 and Figure 4 , the present invention also discloses an extruder, which includes a machine base 800. The side of the machine base 800 is provided with the excess material separation device for the extrusion die 300 disclosed in the above embodiment. The machine base 800 is provided with a die seat body 810, and the above-mentioned extrusion die 300 is arranged on the die seat body 810. The machine base 800 is provided with an extrusion device 820 and a discharging device 830 on both sides of the die seat body 810 in the axial direction of the extrusion die 300. The machine base 800 is provided with a die dismounting device and a conveyor belt 840. After the die dismounting device disassembles the extrusion die 300 from the die seat body 810, it places the extrusion die 300 on the conveyor belt 840 and conveys the extrusion die 300 to the excess material separation device for the extrusion die 300 through the conveyor belt 840.

[0052] During the tube material extrusion forming process, the copper ingot is placed between the extrusion device 820 and the extrusion die 300. The extrusion device 820 extrudes the copper ingot towards the extrusion die 300, so that the copper ingot is pressed and passes through the extrusion die 300 to form a rough tube blank. The rough tube blank is removed from the discharging device 830. When the stroke of the extrusion device 820 reaches the maximum value, one round of tube material extrusion forming is completed. At this time, there is still part of the copper ingot remaining on the extrusion die 300. The extruder can cut the tube material to separate the tube material from the extrusion die 300. The die dismounting device can disassemble the extrusion die 300 with excess material from the die seat body 810, and place the disassembled extrusion die 300 on the conveyor belt 840, and convey it to the excess material separation device for the extrusion die 300 through the conveyor belt 840. When the extrusion die 300 is conveyed to the excess material separation device for the extrusion die 300, the excess material separation device for the extrusion die 300 automatically strips the excess material. Therefore, during the use of the extruder, the user does not need to manually transfer the extrusion die 300 with excess material.

[0053] The above 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 but is not limited to 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.
