Aluminum alloy bar extrusion production equipment

Abstract

The present application discloses an extrusion production equipment for aluminum alloy bars, which avoids obstruction of the aluminum alloy bars extruded from the cavity by pushing the slider upward and driving the sleeve separated from the cavity upward. Then, when the bars are cut and taken away, the backward-moving extrusion rod drives the slider backward through the L-shaped connecting rod, so that the slider gradually separates from the inclined block. Driven by spring I, the slider drives the sleeve downward, so that the sleeve can enter the cavity again, so that the bristles on the sleeve brush the inner wall of the cavity in the process of reciprocating into the cavity, and the residual metal chips are taken away.

Description

Technical Field

[0001] The present application relates to the field of metal processing technology, and in particular to an extrusion production equipment for aluminum alloy bars. Background Art

[0002] In the process of aluminum alloy bar production and processing, aluminum and various alloy metals need to be put into the furnace for smelting and mixing first, and then the smelted metal liquid is poured into the mold for cooling and solidification to form the initial shape of the aluminum alloy bar. After that, the rough high-temperature aluminum alloy bar is cut into metal ingots and placed in the extruder. Through the action of the hydraulic extrusion head, the aluminum bar is extruded and deformed in the mold, and then placed in the stretching machine for further stretching deformation to obtain aluminum alloy bars with qualified appearance.

[0003] When extruding aluminum alloy bars, the operator needs to first place the metal ingot into the cavity of the mold, and then extrude the metal ingot through the extrusion head, so that the metal ingot is formed into a rod with a smaller diameter under the limitation of the extrusion force and the mold cavity, and then discharged from the outlet at the other end of the mold cavity, and continuously moved forward through the conveying mechanism, thereby forming a rod with increasing length. The rod is then cut from the appropriate position by a cutting machine, and the cut rod is transported away by the conveying mechanism. In this process, the cooling system is also required to cool the cut rod.

[0004] It is worth noting that after the extrusion is completed, a part of the metal often remains in the cavity. At this time, the extrusion head needs to be withdrawn, and the operator needs to take out the residual metal in the cavity and put in a new metal ingot before the next extrusion operation can be carried out, which is time-consuming and labor-intensive. At the same time, after the metal ingot is extruded and rubbed, it is easy for metal scraps to remain on the inner wall of the cavity. These residual metal scraps will increase the friction of the inner wall of the cavity, causing friction and wear on the extruded aluminum alloy bar. The large amount of accumulated scraps can also easily cause irregular deformation of the aluminum alloy bar when it is extruded, affecting the quality of the finished product. Summary of the invention

[0005] The present application proposes an extrusion production equipment for aluminum alloy bars, which is provided with a carrying ring to provide an area for placing metal ingots, a sleeve with a brush to clean the inner wall of the cavity, a slider and an inclined block to drive the sleeve to move up and down, and a push rod is pushed into the movable hole by converting the diameter value of the metal ingot that is reduced after being extruded and deformed into a forward speed, and the push rod is pushed by spring III to discharge the excess metal ingot in the cavity. The reciprocating motion of the push rod provides an impact airflow to the brush bristles for cleaning, so as to solve the problem of residual metal ingots and residual waste chips in the cavity of the existing extruder.

[0007] Preferably, the mold cavity presents three sections of holes with different diameters in the horizontal direction, and the three sections of holes include a large-diameter cylindrical hole, a conical hole connected to one end of the large-diameter cylindrical hole, and a small-diameter hole connected to the small-diameter end of the conical hole, for providing space for gradual deformation of the aluminum alloy ingot.

[0008] Preferably, a load-bearing ring is provided at one end of the mold base facing the hydraulic assembly for initially placing the metal ingot. The diameter value of the extrusion rod, the inner diameter value of the load-bearing ring and the diameter value of the hole of the large diameter value of the cavity are the same, and the center lines coincide, so as to ensure that the extrusion rod pushes the metal ingot into the cavity.

[0009] Preferably, a sliding groove is provided at one end of the positioning seat away from the L-shaped connecting rod, and symmetrical blocking blocks are provided on both sides of the top of one end of the sliding block facing the sliding groove. The blocking blocks are movably sleeved in the sliding groove to limit the movement of the sliding block, and a uniformly distributed spring I is connected between the top of the sliding block and the top of the sliding groove to provide power for resetting the sliding block.

[0010] Preferably, a support plate is provided at the bottom of the heat preservation seat, and a tilting block is provided at the top of the support plate. An inclined surface II is provided at one end of the tilting block facing the slider, and an inclined surface I is provided at one end of the slider facing the tilting block. The inclined surfaces I and II have the same inclination angle, which are used to provide power for the slider to lift up when moving forward.

[0011] Preferably, a movable hole is opened in the sleeve, a push rod is arranged in the movable hole, and a spring III is arranged between one end of the push rod located in the movable hole and the end of the movable hole away from the push rod, which is used to receive power provided by the metal bar and store energy to provide power for resetting the push rod.

[0012] Preferably, a magnet I is provided in the mold base, a sliding groove is provided on the sleeve, an insert block is sleeved in the sliding groove, a magnet II is connected to the top of the insert block, a spring II is provided between the top of the magnet II and the bottom of the sliding groove, the magnet II is located below the magnet I, the magnet I provides suction for the magnet II, and a slot is provided on the top of the push rod for limiting the position of the push rod.

[0013] Preferably, the width of the slot is greater than the width of the insert, so as to provide a buffered moving distance.

[0014] Preferably, a one-way valve I is provided at one end of the sleeve away from the push rod, and the movable hole is connected to the outside through the one-way valve I, and is used to absorb the outside air into the movable hole. An annular air distribution cavity is provided in the sleeve, and a one-way valve II is sleeved in the sleeve. The one-way valve II is close to the one-way valve I, and the movable hole is connected to the air distribution cavity through the one-way valve II, and is used to input the air in the movable hole into the air distribution cavity. Uniformly distributed air leakage holes are provided on the sleeve, and the air leakage holes are located between the uniformly distributed bristles. The air distribution cavity is connected to the outside through the air leakage holes, and is used to discharge the air in the air distribution cavity to clean the bristles.

[0015] The present application provides an extrusion production equipment for aluminum alloy bars. By setting a load ring with the same inner diameter value at the cavity opening of the die base, the operator only needs to place the aluminum alloy ingot on the load ring and then push the aluminum alloy ingot into the cavity through the extrusion rod for extrusion molding, thereby reducing the workload of the operator in inserting the aluminum alloy ingot into the cavity.

[0016] At the same time, when the extrusion rod moves forward, the slider will be driven forward through the L-shaped connecting rod, so that the slider contacts the inclined block, and under the extrusion of the inclined surface of the slider and the inclined surface of the inclined block, the slider is pushed upward and the sleeve that is separated from the cavity is driven upward to avoid obstruction of the aluminum alloy bar extruded from the cavity. Then, when the bar is cut and taken away, the backward extrusion rod will drive the slider to move backward through the L-shaped connecting rod, so that the slider gradually separates from the inclined block, and driven by spring I, the slider drives the sleeve to move downward, so that the sleeve can enter the cavity again, so that the bristles on the sleeve brush the inner wall of the cavity during the process of reciprocating into the cavity, and take away the residual metal chips.

[0017] At the same time, when the extrusion rod moves forward to extrude the metal ingot, due to the continuous reduction in the diameter of the cavity, the speed at which the deformed metal ingot advances is greater than the speed at which the sleeve moves away from the metal ingot, so that the deformed and advancing metal ingot pushes the push rod to move forward synchronously, causing relative displacement between the push rod and the sleeve, causing the push rod to continuously compress the spring II and continuously reduce the space of the movable hole, discharging the air in the movable hole to the air distribution cavity through the one-way valve II, and then discharging the air from the air vent, providing airflow impact between the bristles, flushing the waste debris between the bristles with airflow, and maintaining the cleanliness of the bristles.

[0018] At the same time, after magnet II on the sleeve moves away from magnet I, it will no longer obtain the upward attraction of magnet I, so that the compressed spring II can push the plug block downward. When the position of the slot on the moving push rod reaches the bottom of the plug block, spring II can drive the plug block to move downward and insert it into the slot. When the push rod follows the sleeve to move upward and separates from the aluminum alloy bar, the plug block can limit the push rod to reset through the slot, so that spring III maintains a compressed energy storage state. When the push rod enters the cavity again, magnet II moves to the position below magnet I, and magnet I will attract magnet II to drive the plug block to lift up, so that the compressed spring III pushes the push rod to quickly reset, so that the push rod provides impact force on the metal ingot remaining in the cavity, so that the remaining metal ingot is pushed out of the cavity, and separates from the carrying ring and falls to the bottom, thereby completing the purpose of automatic discharge.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Embodiment 1

[0030] See also Figures 1 to 3 , including a hydraulic assembly 1, in which an extrusion rod 2 is movably sleeved, so that the hydraulic assembly 1 can drive the extrusion rod 2 to reciprocate, so that the extrusion rod 2 enters the cavity 8 when moving forward, and the metal ingot in the extrusion cavity 8 is deformed to form an aluminum alloy bar that is extruded from the cavity 8. One end of the hydraulic assembly 1 is bolted with two symmetrical connecting columns 3, and the end of the connecting column 3 away from the hydraulic assembly 1 is fixedly connected with a heat preservation seat 4. A horizontally penetrating rectangular hole is opened in the center of the heat preservation seat 4, and a rectangular die seat 7 is fixedly sleeved in the rectangular hole by bolts, so that the heat preservation seat 4 can provide a fixed point position to the die seat 7, so that the metal ingot extruded in the die seat 7 will not drive the die seat 7 to move, resulting in extrusion failure. At the same time, according to the requirements of different aluminum alloy bar shapes, it is only necessary to replace the die seat 7 that meets the requirements.

[0031] See also Figure 3 A horizontally penetrating cavity 8 is provided at the center of the die base 7. The cavity 8 presents three sections of holes with different diameters in the horizontal direction. The hole close to the hydraulic assembly 1 has a large diameter, the hole in the middle of the three sections is truncated cone-shaped, and the hole far away from the hydraulic assembly 1 has a small diameter. The end of the middle hole with a large diameter is connected to the end of the hole close to the hydraulic assembly 1, and the end of the middle hole with a small diameter is connected to the end of the hole far away from the hydraulic assembly 1, so that the initial metal ingot can enter the large-diameter hole of the cavity 8, and then, under extrusion, it continuously deforms following the gradually changing diameter value of the middle hole, and finally enters the small-diameter hole to fix the shape after deformation to obtain a finished product.

[0032] See also Figures 2 to 3 A load ring 9 is welded to one end of the die base 7 facing the hydraulic assembly 1. The diameter value of the extrusion rod 2, the inner diameter value of the load ring 9 and the diameter value of the hole of the large diameter value of the cavity 8 are the same, and the axis lines coincide, so that the operator can directly place the metal ingot in the load ring 9 without inserting it into the cavity 8. At this time, only the extrusion rod 2 needs to be continuously advanced to push the metal ingot in the load ring 9 into the cavity 8 for extrusion deformation. Embodiment 2

[0033] See also Figures 1 to 4 On the basis of the first embodiment, an L-shaped connecting rod 10 is fixedly connected to the bottom of the extrusion rod 2, and a positioning seat 11 is fixedly connected to the end of the L-shaped connecting rod 10 away from the extrusion rod 2, so that when the extrusion rod 2 moves forward or backward, it can drive the positioning seat 11 to move synchronously through the L-shaped connecting rod 10, and a sliding groove 12 is provided at the end of the positioning seat 11 away from the L-shaped connecting rod 10, and a slider 13 is movably connected in the sliding groove 12. Symmetrical blocks 131 are arranged on both sides of the top of the end of the slider 13 facing the sliding groove 12, and the blocks 131 are movably sleeved in the sliding groove 12, so that the slider 13 can be restricted within the movable range of the sliding groove 12 through the blocks 131, and a uniformly distributed spring Ⅰ14 is fixedly connected between the top of the slider 13 and the top of the sliding groove 12, so that the slider 13 can compress the spring Ⅰ14 after moving up, and after the slider 13 loses the downward limiting force, the compressed spring Ⅰ14 can push the slider 13 to move down and reset.

[0034] See also Figures 1 to 3 , Figure 6 The top of the slider 13 is fixedly connected with a fixing plate 15, and the top of the fixing plate 15 is welded with a transition ring 16, so that when the slider 13 moves upward, it can drive the transition ring 16 to move upward through the fixing plate 15. At this time, the aluminum alloy bar extruded out of the cavity 8 can move through the transition ring 16. The top of the transition ring 16 is welded with a sleeve 17, and the sleeve 17 is inserted into the hole of the small diameter value of the cavity 8. The circumferential surface of the sleeve 17 is plugged with uniformly distributed bristles 30. The bristles 30 can be silicate brushes, metal wire brushes with moderate softness, etc. When the L-shaped connecting rod 10 moves forward, it can drive the slider 13 to move forward through the positioning seat 11, so that the slider 13 can drive the sleeve 17 to move forward through the fixing plate 15 and the transition ring 16, so that the sleeve 17 gradually separates from the cavity 8. At this time, the bristles 30 will brush the inner wall in contact with the cavity 8 once. When the L-shaped connecting rod 10 retreats and resets, it can drive the sleeve 17 to be inserted into the cavity 8 again, so that the bristles 30 brush the inner wall in contact with the cavity 8 for a second time. In this reciprocating manner, the metal chips remaining on the inner wall of the small diameter hole of the cavity 8 are reduced.

[0035] See also Figures 1 to 3The bottom of the heat preservation seat 4 is fixedly connected with a support plate 5, and the top of the support plate 5 is fixedly connected with an inclined block 6. An inclined surface II is provided at one end of the inclined block 6 facing the slider 13, and an inclined surface I is provided at one end of the slider 13 facing the inclined block 6. The inclined surface I and the inclined surface II have the same inclination angle, so that when the slider 13 moves forward, the inclined surface I on the slider 13 will contact the inclined surface II on the inclined block 6. At this time, the slider 13 that continues to move forward will squeeze the inclined block 6. Since the position of the inclined block 6 remains unchanged, the slider 13 will be gradually pushed upward due to the influence of the two inclined surfaces, so that the slider 13 drives the sleeve 17 that is separated from the cavity 8 to move upward, thereby preventing the sleeve 17 from affecting the extrusion of the aluminum alloy bar. Embodiment 3

[0036] See also Figure 3 , Figures 5 and 6 On the basis of the second embodiment, a movable hole 18 is opened in the sleeve 17, and a push rod 27 is movably sleeved in the movable hole 18. The end of the push rod 27 away from the sleeve 17 extends into the cavity 8. A spring III 29 is fixedly connected between the end of the push rod 27 located in the movable hole 18 and the end of the movable hole 18 away from the push rod 27. When the extrusion rod 2 moves forward to extrude the metal ingot, due to the continuous reduction in the diameter value of the cavity 8, the speed at which the deformed metal ingot advances is greater than the speed at which the sleeve 17 moves away from the metal ingot, so that the deformed and advancing metal ingot pushes the push rod 27 to move forward synchronously, so that the push rod 27 and the sleeve 17 are relatively displaced, so that the push rod 27 can continuously compress the spring III 29 and reduce the space of the movable hole 18.

[0037] See also Figure 6 to Figure 7A magnet I71 is fixedly sleeved in the mold base 7, a sliding groove 21 is opened on the sleeve 17, the sliding groove 21 is close to the opening of the movable hole 18, the slot of the sliding groove 21 is opposite to the push rod 27, an insert block 24 is movably sleeved in the sliding groove 21, a magnet II 23 is fixedly connected to the top of the insert block 24, a spring II 22 is fixedly connected between the top of the magnet II 23 and the bottom of the sliding groove 21, the magnet II 23 is located below the magnet I71, the magnet I71 provides suction for the magnet II 23, the magnet I71 and the magnet II 23 are high temperature resistant magnets. A slot 28 is provided on the top of the push rod 27. The slot 28 is away from the opening of the movable hole 18. After the magnet II 23 on the sleeve 17 is away from the magnet I 71, it will no longer obtain the upward attraction of the magnet I 71, so that the compressed spring II 22 can push the plug block 24 to move downward. When the position of the slot 28 on the moving push rod 27 reaches the bottom of the plug block 24, the spring II 22 can drive the plug block 24 to move downward and insert into the slot 28. When the push rod 27 follows the sleeve 17 to move upward and is in contact with the aluminum alloy After the rod is detached, the insert block 24 can limit the reset of the push rod 27 through the slot 28, so that the spring III 29 maintains a compressed energy storage state. When the push rod 27 enters the cavity 8 again, the magnet II 23 moves to the position below the magnet I 71, and the magnet I 71 will attract the magnet II 23 to drive the insert block 24 to lift up. At this time, the spring II 22 is compressed, and at the same time, the compressed spring III 29 pushes the push rod 27 to reset quickly, so that the push rod 27 provides an impact force on the metal ingot remaining in the cavity 8, so that the remaining metal ingot is pushed out of the cavity 8, and falls below the load ring 9, thereby completing the purpose of automatic discharge. The width value of the slot 28 is greater than the width value of the insert block 24, so that after the insert block 24 is inserted into the slot 28, the moving aluminum alloy bar can still push the push rod 27 to move a distance. At this time, the extrusion rod 2 is still in a moving state, driving the sleeve 17 to be in a moving state, so that when the sleeve 17 is lifted up, it can still drive the push rod 27 to lift up synchronously, and does not hinder the continuous movement of the aluminum alloy bar. Embodiment 4

[0038] See also Figures 5 and 6 On the basis of the third embodiment, a one-way valve Ⅰ25 is fixedly sleeved on one end of the sleeve 17 away from the push rod 27, and the movable hole 18 is connected to the outside through the one-way valve Ⅰ25. When the spring Ⅲ29 pushes the push rod 27 to move and hits the remaining metal ingot, the effective space in the movable hole 18 will be increased. At this time, the increase in space will form a negative pressure, so that the outside air can enter the movable hole 18 through the one-way valve Ⅰ25.

[0039] See also Figure 6 to Figure 7An annular air distribution cavity 19 is provided in the sleeve 17, and a one-way valve II 26 is fixedly sleeved in the sleeve 17. The one-way valve II 26 is close to the one-way valve I 25. The movable hole 18 is connected with the air distribution cavity 19 through the one-way valve II 26, so that when the space of the movable hole 18 is continuously reduced, the air in the movable hole 18 can be squeezed into the air distribution cavity 19 through the one-way valve I 25. Uniformly distributed air leakage holes 20 are provided on the sleeve 17, and the air leakage holes 20 are located between the uniformly distributed bristles 30. The air distribution cavity 19 is connected with the outside world through the air leakage holes 20, so that the air squeezed into the air distribution cavity 19 is affected by the small space of the air distribution cavity 19 and the small gap of the air leakage holes 20, and can discharge a fast-flowing airflow through the air leakage holes 20, providing airflow impact to the bristles 30, flushing the waste debris between the bristles 30 with airflow, and maintaining the cleanliness of the bristles.
