The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0025] The present application will be described below in conjunction with Figures 1-6 An aluminum profile extruding machine is described.

[0026] As shown in Figure 1 and Figure 2 , in one embodiment, an aluminum profile extruding machine comprises a frame 1, a moving plate 2, a moving extruding seat 3, a crucible 4 and an extruding piece 5.

[0027] The frame 1 has an X-direction track plate 11.

[0028] The moving plate 2 is slidingly installed on the X-direction track plate 11.

[0029] The moving extruding seat 3 is installed on the moving plate 2.

[0030] The crucible 4 has an extruding cavity 41 (see Figure 6 ) and is slidingly installed on the X-direction track plate 11 for containing an aluminum bar to be extruded.

[0031] The extruding piece 5 has an extruding rod 51 and is slidingly installed on the moving extruding seat 3 for extruding the aluminum bar in the extruding cavity 41.

[0032] It should be noted that the moving extruding seat 3 comprises a Y-direction track plate, moving sliders and a backing plate, the Y-direction track plate is installed on the moving plate 2, the moving sliders are installed on the Y-direction track plate, and the backing plate is detachably installed between the moving sliders and the extruding piece 5. Preferably, the Y-direction track plate is locked and installed on the moving plate 2 in a bolted manner, the moving sliders are two groups, and the two groups of moving sliders are symmetrically arranged on both sides of the X-direction center line of the Y-direction track plate. Preferably, the backing plate is a copper plate.

[0033] It should be noted that one end of the extrusion rod 51 is detachably mounted on the extrusion member 5, and the other end of the extrusion rod 51 extends to the outside of the extrusion member 5 in the direction of the ingot containing cylinder 4, and the inner diameter of the extrusion cavity 41 matches the outer diameter of the outer side end of the extrusion rod 51.

[0034] The moving extrusion seat 3 comprises a driving source 31, a driving rack 32 and a universal head 33, one end of the driving rack 32 is in transmission connection with the driving source 31, and the other end is provided with the universal head 33; It should be noted that the driving source 31 comprises a servo motor, a speed reducer and a driving gear, the input end of the speed reducer is connected with the rotating rod of the servo motor, the rotating rod of the output end of the speed reducer is fixedly connected with the driving gear, and the driving gear is in meshing transmission with the driving rack 32.

[0035] The side wall of the extrusion member 5 adjacent to the driving source 31 has a connecting groove 52 (see Figure 3 ), the end of the universal head 33 away from the driving rack 32 is movably mounted in the connecting groove 52, a hard gasket 52-1 and a flexible gasket 52-2 are mounted in the connecting groove 52, one side surface of the flexible gasket 52-2 is in abutting connection with the inner wall of the connecting groove 52 opposite the slot, and the surface of the flexible gasket 52-2 opposite the slot of the connecting groove 52 is in abutting connection with the hard gasket 52-1.

[0036] Preferably, the hard gasket 52-1 is a steel plate, and the flexible gasket 52-2 is a cowhide plate.

[0037] Specifically, when adjusting the position of the extrusion member 5 along the Y direction, the servo motor drives the driving gear to rotate through the speed reducer, the driving gear drives the driving rack 32 to displace, the driving rack 32 drives the extrusion member 5 to move through the universal head 33, and in this process, the extrusion member 5 will exert a certain frictional force on the backing plate to drive the backing plate to displace.

[0038] And the frictional force exerted by the extrusion member 5 on the backing plate will cause the backing plate to wear with the increase of the number of uses, thereby causing the height of the extrusion member 5 to deviate.

[0039] When the extrusion member 5 is driven to move along the X direction to extrude the aluminum rod, the reaction force exerted by the aluminum rod on the extrusion member 5 will cause the extrusion member 5 to deviate backward along the X direction.

[0040] By using the universal head 33 to connect the driving rack 32 and the extrusion member 5, when the height of the extrusion member 5 deviates or deviates backward, the extrusion member 5 can swing relative to the universal head 33 along the height direction and the X direction, so as to avoid the end of the driving rack 32 from being deformed by being driven to displace by the extrusion member 5. And in the process of the extrusion member 5 swinging relative to the universal head 33, the hard gasket 52-1 is in hard connection with the universal head 33 to maintain the abutting effect on the universal head 33, and the flexible gasket 52-2 provides floating space for the universal head 33 to swing in the connecting groove 52.

[0041] like Figure 3 As shown, in one embodiment, the universal head 33 includes a ball head 33-1 and a transfer rod 33-2. The ball head 33-1 is installed in the connecting groove 52. One end of the transfer rod 33-2 is connected to the ball head 33-1, and the other end thereof extends to the outside of the connecting groove 52. The connecting groove 52 is cylindrical in shape, and the inner diameter of the connecting groove 52 matches the outer diameter of the ball head 33 - 1 .

[0042] In this embodiment, a pressure plate 53 is installed on the side wall of the extrusion member 5. The pressure plate 53 is detachable and is installed on the outside of the slot of the connecting slot 52. The pressure plate 53 is used to limit the universal head 33 in the connecting slot 52, and the pressure plate 53 and the hard gasket 52-1 together press the universal head 33 tightly.

[0043] In this embodiment, the surface of the pressure plate 53 corresponding to the connecting groove 52 has a through hole 53-1, and the inner diameter of the through hole 53-1 is larger than the outer diameter of the transfer rod 33-2, providing displacement space for the transfer rod 33-2 to swing relative to the pressure plate 53. The corner of the through hole 53-1 adjacent to the connecting groove 52 has an abutment portion 53-11, and the abutment portion 53-11 is an arc-shaped inner chamfer that matches the ball head 33-1.

[0044] Preferably, the extrusion member 5 is provided with threaded holes along the edge of the connection groove 52, and the pressing plate 53 is installed on the side wall of the extrusion member 5 in a bolted manner. The pressing plate 53 is disc-shaped.

[0045] Specifically, under the thrust of the flexible gasket 52 - 2 , the hard gasket 52 - 1 causes the ball head 33 - 1 to abut against the abutting portion 53 - 11 of the abutting plate 53 .

[0046] In this embodiment, the end of the adapter rod 33 - 2 facing away from the ball head 33 - 1 has a screw hole; One end of the driving rack 32 adjacent to the ball head 33 - 1 has a connecting screw 32 - 1 and a locking nut 32 - 2 . The connecting screw 32 - 1 is adapted to the screw hole, and the inner wall of the locking nut 32 - 2 has a threaded surface with the same rotation direction as the screw hole.

[0047] Specifically, when the ball head 33-1 is installed on the driving rack 32, first, the locking nut 32-2 is screwed onto the connecting screw 32-1 in the clockwise direction, then the adapter rod 33-2 is screwed onto the connecting screw 32-1 in the clockwise direction, and then the locking nut 32-2 is rotated counterclockwise to abut the locking nut 32-2 against the adapter rod 33-2. Since the locking nut 32-2 and the adapter rod 33-2 need to be rotated counterclockwise to be unscrewed from the connecting screw 32-1, and at this time the locking nut 32-2 and the adapter rod 33-2 abut and there is a friction force, thereby increasing the resistance of the adapter rod 33-2 to rotate counterclockwise, and further enhancing the locking effect of the adapter rod 33-2 and the threads on the connecting screw 32-1.

[0048] Since the extrusion rod 51 still has some aluminum scraps on the outer wall of the adhering end after separating from the aluminum rod after extrusion, when the extrusion rod 51 extrudes the aluminum rod again, the scraps remaining on the surface of the extrusion rod 51 will affect the flatness of the aluminum material after extrusion.

[0049] In the embodiment, the extrusion member 5 includes an extrusion plate 54 (see Figure 2 ), and the extrusion rod 51 is installed on the extrusion plate 54; As shown in Figure 4 and Figure 5 , in one embodiment, the extrusion rod 51 includes a driving rod 51-1 and an extrusion head 51-2, the driving rod 51-1 is detachably installed on the extrusion plate 54, and the extrusion head 51-2 is fixedly installed on the driving rod 51-1.

[0050] In the embodiment, the extrusion head 51-2 has a sliding cavity 51-22, the sliding cavity 51-22 has a connecting rod 51-23 adjacent to the inner wall of one end of the driving rod 51-1, and the cleaning member 55 is slidingly installed on the connecting rod 51-23. The connecting rod 51-23 has a translation slot 51-24 and a spiral slot 51-26, and the translation slot 51-24 and the spiral slot 51-26 are sequentially arranged and communicated along the direction from the driving rod 51-1 to the extrusion head 51-2.

[0051] In the embodiment, the cleaning member 55 includes a connecting sleeve 55-1 and a connecting chuck 55-2, the connecting sleeve 55-1 is slidingly sleeved on the connecting rod 51-23, the inner wall of the connecting sleeve 55-1 has a sliding column 55-11, and the connecting chuck 55-2 is detachably installed on one end of the connecting sleeve 55-1 away from the connecting rod 51-23. In the initial state, the end of the sliding column 55-11 away from the connecting sleeve 55-1 is slidingly installed in the spiral slot 51-26.

[0052] In the embodiment, the connecting chuck 55-2 comprises an outer circular plate 55-22 and an inner sleeve 55-24, one end of the inner sleeve 55-24 is detachably mounted at the end of the connecting sleeve 55-1 away from the connecting rod 51-23, and the other end is fixedly connected with the outer circular plate 55-22, and the axis of the inner sleeve 55-24 coincides with that of the outer circular plate 55-22; Preferably, the end of the connecting sleeve 55-1 away from the connecting rod 51-23 has an adapter rod with a connecting screw hole, and the inner sleeve 55-24 has a connecting hole, by sleeving the inner sleeve 55-24 on the adapter rod, aligning the connecting hole with the connecting screw hole, and screwing a screw through the connecting hole into the connecting screw hole, the inner sleeve 55-24 is fixed on the connecting sleeve 55-1 together with the circular plate. Through this connection mode, it is convenient to disassemble and replace the connecting chuck 55-2 subsequently.

[0053] The outer arc wall of the outer circular plate 55-22 has a plurality of scraping claws 55-21, which are circularly arrayed with the center of the outer circular plate 55-22 as the center, and the surface of the extrusion head 51-2 away from the driving rod 51-1 is provided with a plurality of retraction grooves 51-21, the shape and number of the retraction grooves 51-21 are matched with those of the scraping claws 55-21, and the retraction grooves 51-21 are circularly arrayed on the extrusion head 51-2.

[0054] Preferably, the spiral groove 51-26 is a one-third turn spiral, the scraping claws 55-21 are three groups, and the retraction grooves 51-21 are three groups. Alternatively, the spiral groove 51-26 is a one-fourth turn spiral, the scraping claws 55-21 are four groups, and the retraction grooves 51-21 are four groups.

[0055] Preferably, the scraping claw 55-21 comprises a scraping strip and a stop plate, the stop plate is fixedly installed at the end of the scraping strip away from the inner sleeve 55-24, and the stop plate is perpendicular to the scraping strip. By setting the stop plate, the contact surface of the extrusion head 51-2 and the aluminum bar when they first abut is increased, and the initial pressure on the aluminum bar when it is first extruded is reduced, thereby protecting the surface of the aluminum bar.

[0056] Specifically, when the extrusion rod 51 extrudes the aluminum bar in the crucible cylinder 4, the stop plate first abuts against the aluminum bar, then the driving rod 51-1 continuously displaces, while the outer circular plate 55-22, the inner sleeve 55-24, and the connecting sleeve 55-1 remain unchanged in position, so as to make the slide column 55-11 start to slide along the spiral groove 51-26, the slide column 55-11 drives the connecting sleeve 55-1 to synchronously displace, the connecting sleeve 55-1 drives the outer circular plate 55-22 and the scraping claw 55-21 to synchronously displace through the inner sleeve 55-24, so as to make the scraping claw 55-21 adhere to the aluminum bar and the outer circular plate 55-22 rotate, and clean the aluminum scraps adhered on the abutting surface of the aluminum bar and the outer circular plate 55-22.

[0057] When the slide 55-11 moves from the spiral groove 51-26 into the translation groove 51-24, the scraping claw 55-21 is turned to a position directly opposite the retraction groove 51-21, and as the slide 55-11 moves in the translation groove 51-24, the scraping claw 55-21 is moved into the retraction groove 51-21 until the outer wall of the extrusion head 51-2 is flush with the outer wall of the extrusion head 51-2, at which time the outer wall of the extrusion head 51-2 is also in abutment with the outer end of the aluminum bar, and the extrusion head 51-2, the scraping claw 55-21 and the outer circular plate 55-22 are pushed by the driving rod 51-1 to extrude the aluminum bar.

[0058] After the extrusion of the aluminum bar is completed, the driving rod 51-1 pulls the extrusion head 51-2 to move in the opposite direction, so that the extrusion head 51-2 is separated from the aluminum bar, and in this process, the slide 55-11 moves from the translation groove 51-24 back into the spiral groove 51-26, that is, the scraping claw 55-21 is first moved out of the retraction groove 51-21, and then is driven to rotate in the opposite direction to the extrusion head 51-2 and the aluminum bar, so that the residual debris on the extrusion head 51-2 is scraped off in time, and the outer end surface of the aluminum bar is also assisted to be scraped and shaped.

[0059] Considering that the aluminum profile extruder is used in low-temperature areas, there is a lot of heat loss in the process of taking the aluminum bar out of the heating furnace and moving it into the ingot holding cylinder 4, and the material of the surface of the aluminum bar after cooling down may change, which affects the extrusion effect.

[0060] As shown in Figure 6 In one embodiment, the ingot holding cylinder 4 has a plurality of heating grooves 42, and the heating grooves 42 are arranged in a circular array. A plurality of straight-insert type heating wires 42-1 are inserted into the heating grooves 42, and the plurality of straight-insert type heating wires 42-1 are arranged in a circular array along the edge of the extrusion cavity 41. A temperature control probe 43 is installed on the side wall of the ingot holding cylinder 4, and the temperature control probe 43 is used to detect the ambient temperature in the ingot holding cylinder 4.

[0061] Preferably, the temperature control probe 43 is a thermocouple or other temperature measuring sensor.

[0062] Specifically, the temperature control probe 43 monitors the ambient temperature in the ingot holding cylinder 4 in real time and feeds back the monitoring data to the PLC system. The PLC system adjusts the working state of the straight-insert type heating wire 42-1 in real time according to the feedback to ensure that the ambient temperature in the ingot holding cylinder 4 is within a specified temperature range, so as to heat and keep warm the aluminum bar in the ingot holding cylinder 4, so that the aluminum profile extruder can be used in low-temperature areas.

[0063] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present disclosure.
