Aluminum bar peeling device for seamless aluminum tube production

Abstract

The present invention discloses an aluminum rod peeling device for seamless aluminum tube production. The heated aluminum rod is placed on a support seat, and then the aluminum rod is pushed towards a circular cutter by a pushing member. When the aluminum rod passes through the circular cutter, the circular cutter peels off the oxide layer on the outer peripheral wall of the aluminum rod, and the peeled oxide layer adheres to the circular cutter. Then, the circular pushing plate is moved so that the circular pushing plate pushes off the aluminum rod oxide layer adhered to the circular cutter. At this time, the support seat is in the second working position, and at this time, the support seat does not block the material dropping port, so that after the aluminum rod oxide layer detaches from the circular cutter, it falls into the material dropping port and then drops into the storage basket. The present invention can automatically push off the aluminum rod oxide layer adhered to the circular cutter and collect it into the storage basket, thereby reducing the workload of operators, shortening the waiting time for aluminum rod peeling, and improving the efficiency of aluminum rod peeling.

Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile processing, and specifically to an aluminum bar peeling device for seamless aluminum tube production. Background Art

[0002] When producing seamless aluminum tubes, generally, the aluminum bar is first heated to the required temperature, and then the aluminum bar is formed into a seamless aluminum tube by backward extrusion. Since an oxide layer is easily formed on the surface of the seamless aluminum tube during heating, a peeling device is required to remove the oxide layer on the surface of the aluminum bar before backward extrusion of the aluminum bar.

[0003] However, after the oxide layer on the surface of the aluminum bar is peeled off by a tool in the current aluminum bar peeling device, the oxide layer of the aluminum bar is easily adhered to the tool. This requires the operator to manually remove the oxide layer of the aluminum bar on the tool each time, which greatly increases the labor amount of the operator, resulting in a long waiting time for aluminum bar peeling and low efficiency of aluminum bar peeling. Summary of the Invention

[0004] The present application provides an aluminum bar peeling device for seamless aluminum tube production, which can automatically push down the oxide layer of the aluminum bar adhered to the annular tool and collect it into the storage basket, thereby reducing the workload of the operator, shortening the waiting time for aluminum bar peeling, and improving the efficiency of aluminum bar peeling.

[0012] A first driving mechanism, used to drive the support seat to slide along the first guiding component so that the support seat switches between a first working position and a second working position;

[0013] A pushing member, slidably arranged on the second guiding component;

[0014] A second driving mechanism is used to drive the pushing member to slide along the second guiding component, so that the pushing member approaches or moves away from the annular cutter. When the pushing member approaches the annular cutter, the pushing member pushes the aluminum rod on the supporting seat towards the annular cutter. When the aluminum rod passes through the annular cutter, the oxide layer on the outer peripheral wall of the aluminum rod is peeled off by the annular cutter, and the peeled oxide layer adheres to the annular cutter;

[0015] A third driving mechanism is used to drive the annular pushing plate to move, so that the annular pushing plate pushes off the aluminum rod oxide layer adhered to the annular cutter. After the aluminum rod oxide layer detaches from the annular cutter, it falls to the blanking port and then drops into the storage basket;

[0016] When the pushing member pushes the aluminum rod on the supporting seat towards the annular cutter, the supporting seat is in the first working position. At this time, the supporting seat is close to the annular cutter, and the supporting seat blocks the blanking port; when the annular pushing plate pushes off the aluminum rod oxide layer adhered to the annular cutter, the supporting seat is in the second working position. At this time, the supporting seat is far away from the annular cutter, and the supporting seat does not block the blanking port.

[0017] Preferably, a positioning groove for placing the aluminum rod is provided on the upper surface of the supporting seat. The positioning groove extends along the direction towards the annular cutter. A plurality of rotatable roller shafts are provided on both side walls of the positioning groove at intervals along the extending direction of the positioning groove. When the aluminum rod is in the positioning groove and moves towards the annular cutter, both sides of the aluminum rod are in rolling contact with the roller shafts on both sides of the positioning groove respectively.

[0018] Preferably, the cross-section of the positioning groove is trapezoidal in reverse. Grooves are provided on both side walls of the positioning groove, and the roller shafts are all arranged in the grooves. The roller shafts on both sides of the positioning groove are respectively parallel to the two side walls of the positioning groove.

[0019] Preferably, the annular cutter includes an annular cutter body. One end of the annular cutter body facing the pushing member is an annular cutting edge. A plurality of cutters are provided on the outer peripheral wall of the annular cutter body. The plurality of cutters are circumferentially spaced apart around the axis of the annular cutter body. The cutting edge of each cutter faces the pushing member, the cutting edge of each cutter extends along the radial direction of the annular cutter body, and the cutting edge of each cutter is flush with the cutting edge;

[0020] The annular pushing plate is movably sleeved on the annular cutter. A plurality of first notches are provided on the inner peripheral edge of the annular pushing plate. The plurality of first notches are circumferentially spaced apart around the axis of the annular pushing plate. The first notches are arranged in one-to-one correspondence with the cutters. In the moving direction of the annular pushing plate, each first notch is directly opposite to the corresponding cutter, so that each cutter can pass through the corresponding first notch and pass through the annular pushing plate when the annular pushing plate moves.

[0021] Preferably, a stop block is provided between any two adjacent cutters along the circumferential direction of the annular cutter body;

[0022] A plurality of second notches are provided on the inner peripheral edge of the annular pushing plate. The plurality of second notches are circumferentially spaced around the axis of the annular pushing plate. The second notches are arranged in one-to-one correspondence with the stoppers. In the moving direction of the annular pushing plate, each second notch is directly opposite to the corresponding stopper, so that each stopper can pass through the corresponding second notch and pass through the annular pushing plate when the annular pushing plate moves.

[0023] Preferably, one surface of each stopper facing the pusher is an arc-shaped concave surface, so that when the oxide layer of the aluminum rod is peeled off, it can be blocked and guided by the arc-shaped concave surface and rolled up;

[0024] A support plate is rotatably arranged in the blanking port. A motor for driving the support plate to rotate is arranged on the base. An installation groove is arranged on the side wall of the blanking port. A pressing plate and a hydraulic push rod for driving the pressing plate to move horizontally are arranged in the installation groove. The pressing plate is arranged vertically;

[0025] When the annular pushing plate pushes the oxide layer of the aluminum rod adhered to the annular cutting tool into the blanking port, the support plate is in a state of blocking the lower end of the blanking port. The oxide layer of the aluminum rod falls onto the support plate. At this time, the hydraulic push rod drives the pressing plate to move so that the pressing plate pushes the oxide layer of the aluminum rod on the support plate towards the side wall of the blanking port, thereby flattening the oxide layer of the aluminum rod on the support plate. Then the motor drives the support plate to rotate to open the lower end of the blanking port, so that the flattened oxide layer of the aluminum rod on the support plate falls into the storage basket.

[0026] Preferably, a convex portion protruding towards the direction where the pusher is located is provided between any adjacent first notch and second notch along the circumferential direction of the annular pushing plate.

[0027] Preferably, the annular pushing plate is detachably installed on a bottom plate, the bottom plate is movably installed on the frame, and the third driving mechanism drives the annular pushing plate to move by driving the bottom plate to move.

[0028] Preferably, a bushing is provided on the inner wall of the through hole of the frame, and the annular cutting tool is fixedly connected to the bushing.

[0029] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0030] When the aluminum rod peeling device of the present application peels an aluminum rod, the heated aluminum rod is placed on the support base, and then the aluminum rod is pushed towards the annular cutter by the pusher. When the aluminum rod passes through the annular cutter, the annular cutter peels off the oxide layer on the outer peripheral wall of the aluminum rod, and the peeled oxide layer adheres to the annular cutter. Then, the annular pushing plate is moved so that the annular pushing plate pushes off the aluminum rod oxide layer adhered to the annular cutter. At this time, the support base is in the second working position, and at this time, the support base does not block the material dropping port, so that the aluminum rod oxide layer falls into the material dropping port after separating from the annular cutter and then falls into the storage basket. In this way, the aluminum rod peeling device of the present application can automatically push off the aluminum rod oxide layer adhered to the annular cutter and collect it into the storage basket, without the need for manual cleaning of the aluminum rod oxide layer adhered to the annular cutter, shortening the waiting time for aluminum rod peeling. The aluminum rod peeling device can continuously perform peeling operations without waiting, improving the efficiency of aluminum rod peeling, so that the peeled aluminum rod can be quickly supplied to the extrusion equipment, thereby improving the production efficiency of seamless aluminum tubes.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or server comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or modules that are not clearly listed or are inherent to these processes, methods, products or devices.

[0042] As Figures 1 to 8 shown, the aluminum rod peeling device for seamless aluminum tube production in this embodiment includes a base 10, a frame 20, a circular cutter 30, a circular pushing plate 40, a first guiding assembly, a second guiding assembly, a support seat 50, a first driving mechanism, a pushing member 60, a second driving mechanism, and a third driving mechanism.

[0043] A blanking port 11 is provided on the upper surface of the base 10, and a storage basket 12 is placed below the blanking port 11. The storage basket 12 is open at the upper part, so that the aluminum rod oxide layer can fall into the storage basket 12 through the blanking port 11.

[0044] The frame 20 is arranged above the base 10, and the frame 20 is fixedly connected to the upper surface of the base 10. The frame 20 is vertically arranged, and a through hole is provided on the frame 20. The through hole is horizontally arranged and horizontally penetrates the left and right surfaces of the frame 20.

[0045] The circular cutter 30 is fixedly arranged on one side of the frame 20. The circular cutter 30 is coaxially arranged with the through hole. The circular cutter 30 is located directly above the blanking port 11. In this way, when the aluminum rod passes through the circular cutter 30, the circular cutter 30 can peel off the oxide layer on the outer peripheral wall of the aluminum rod. The aluminum rod after removing the oxide layer passes through the through hole and falls onto the carrier table 18. A concave portion 181 for accommodating the aluminum rod after removing the oxide layer is provided on the carrier table 18.

[0046] The annular pushing plate 40 is movably arranged between the frame 20 and the annular cutter 30. The annular pushing plate 40 can move to a state where it is sleeved with the annular cutter 30. At this time, the annular pushing plate 40 and the annular cutter 30 are nested with each other, and the annular pushing plate 40 can push off the aluminum rod oxide layer adhered to the annular cutter 30.

[0047] Specifically, the annular pushing plate 40 is detachably installed on a bottom plate 21 through bolts. The bottom plate 21 is movably installed on the frame 20. The third driving mechanism drives the annular pushing plate 40 to move by driving the bottom plate 21 to move. In this way, the annular pushing plate 40 can be removed from the bottom plate 21 for replacement, which is convenient for the maintenance and repair of the equipment.

[0048] Both the first guiding assembly and the second guiding assembly are arranged on the frame 20. The first guiding assembly includes two horizontally arranged and parallel first guiding rods 101. The second guiding assembly includes two horizontally arranged and parallel second guiding rods 102. The first guiding rods 101 and the second guiding rods 102 are parallel to each other. The first guiding rods 101 and the second guiding rods 102 are both perpendicular to the bottom plate 21. The first guiding rods 101 and the second guiding rods 102 penetrate through the bottom plate 21 and are connected to the frame 20. The bottom plate 21 can slide along the first guiding rods 101 and the second guiding rods 102.

[0049] The supporting seat 50 is slidably sleeved on the two first guiding rods 101, so that the supporting seat 50 can slide along the first guiding rods 101. The upper surface of the supporting seat 50 is used to place the aluminum rod to be skinned. When the aluminum rod is placed on the supporting seat 50, one end of the aluminum rod is aligned with the annular cutter 30.

[0050] The first driving mechanism includes a hydraulic power device and a first connecting rod 103. The first driving mechanism is used to drive the supporting seat 50 to slide along the first guiding rods 101. That is to say, the hydraulic power device can push and pull the supporting seat 50 through the first connecting rod 103, so that the supporting seat 50 can move forward or backward, thereby enabling the supporting seat 50 to switch between the first working position and the second working position.

[0051] A connecting portion 61 is integrally formed on the pushing member 60. The connecting portion 61 is slidably sleeved on the two second guiding rods 102, so that the pushing member 60 can slide along the second guiding rods 102.

[0052] The second driving mechanism includes a hydraulic power device and a second connecting rod 105. The second driving mechanism is used to drive the pushing member 60 to slide along the second guiding rod 102. That is to say, the hydraulic power device can push and pull the pushing member 60 through the second connecting rod 105, so that the pushing member 60 can move forward or backward, thereby making the pushing member 60 approach or move away from the annular cutter 30. When the pushing member 60 approaches the annular cutter 30, the pushing member 60 pushes the aluminum rod on the support seat 50 towards the annular cutter 30. When the aluminum rod passes through the annular cutter 30, the oxide layer on the outer peripheral wall of the aluminum rod is peeled off by the annular cutter 30, and the peeled oxide layer adheres to the annular cutter 30.

[0053] The third driving mechanism includes a hydraulic power device and a third connecting rod 104. The third driving mechanism is used to drive the annular pushing plate 40 to move. That is to say, the hydraulic power device can push and pull the bottom plate 21 through the third connecting rod 104, so that the bottom plate 21 can move forward or backward. The annular pushing plate 40 is installed on the bottom plate 21 through bolts, so that the annular pushing plate 40 moves synchronously with the bottom plate 21. When the annular pushing plate 40 moves, it can push off the aluminum rod oxide layer adhering to the annular cutter 30. After the aluminum rod oxide layer detaches from the annular cutter 30, it falls to the material discharge port 11 and then drops into the storage basket 12.

[0054] When the pushing member 60 pushes the aluminum rod on the support seat 50 towards the annular cutter 30, the support seat 50 is in the first working position. At this time, the support seat 50 is close to the annular cutter 30, so that the distance between the aluminum rod and the annular cutter 30 is relatively close at this time, so as to shorten the forward movement stroke of the aluminum rod. And at this time, the support seat 50 blocks the material discharge port 11, because the material discharge port 11 is located below the annular cutter 30.

[0055] When the annular pushing plate 40 pushes off the aluminum rod oxide layer adhering to the annular cutter 30, the support seat 50 is in the second working position. At this time, the support seat 50 is far away from the annular cutter 30, and the support seat 50 does not block the material discharge port 11. Then, when the aluminum rod oxide layer falls off from the annular cutter 30 at this time, it will fall into the storage basket 12 from the material discharge port 11.

[0056] A positioning groove 51 for placing the aluminum rod is provided on the upper surface of the support seat 50. The positioning groove 51 extends along the direction towards the annular cutter 30. When the aluminum rod is placed on the support seat 50, the positioning groove 51 can limit the position and direction of the aluminum rod, so that the aluminum rod can be aligned with the center of the annular cutter 30. A plurality of rotatable roller shafts 52 are provided on both side walls of the positioning groove 51 at intervals along the extending direction of the positioning groove 51. When the aluminum rod is in the positioning groove 51 and moves towards the annular cutter 30, both sides of the aluminum rod are in rolling contact with the roller shafts 52 on both sides of the positioning groove 51 respectively, which can reduce the friction force when the aluminum rod moves forward in the positioning groove 51.

[0057] The cross-section of the positioning groove 51 is trapezoidal in reverse, and grooves 511 are provided on both side walls of the positioning groove 51. The roller shafts 52 on both sides of the positioning groove 51 are respectively arranged in the grooves 511 on both sides of the positioning groove 51, and the roller shafts 52 on both sides of the positioning groove 51 are respectively parallel to the two side walls of the positioning groove 51. In this way, the positioning groove 51 has a structure that is larger at the top and smaller at the bottom, which is convenient for placing the aluminum rod into the positioning groove 51.

[0058] The annular cutting tool 30 includes an annular tool body 31. One end of the annular tool body 31 facing the pushing member 60 is an annular cutting edge 311, and the diameter of the cutting edge 311 is slightly smaller than the diameter of the aluminum rod. Thus, when the aluminum rod passes through the annular cutting tool 30, the cutting edge 311 can cut the outer peripheral wall of the aluminum rod to peel off the oxide layer on the outer peripheral wall of the aluminum rod. A plurality of cutting tools 32 are provided on the outer peripheral wall of the annular tool body 31, and the plurality of cutting tools 32 are circumferentially spaced apart around the axis of the annular tool body 31. The cutting edge of each cutting tool 32 faces the pushing member 60, the cutting edge of each cutting tool 32 extends along the radial direction of the annular tool body 31, and the cutting edge of each cutting tool 32 is flush with the cutting edge 311. In this way, when the aluminum rod passes through the annular cutting tool 30, the cutting edge 311 cuts the outer peripheral wall of the aluminum rod, and at the same time, the plurality of cutting tools 32 cut the oxide layer on the outer peripheral wall of the aluminum rod along the axial direction of the aluminum rod to divide the oxide layer on the outer peripheral wall of the aluminum rod into a plurality of small pieces, so as to facilitate the collection of the aluminum rod oxide layer.

[0059] Moreover, along the circumferential direction of the annular tool body 31, a blocking block 33 is provided between any two adjacent cutting tools 32. When the aluminum rod passes through the annular cutting tool 30, the aluminum rod oxide layer divided into small pieces between the two cutting tools 32 can be blocked by the blocking block 33, so as to prevent the aluminum rod oxide layer divided into small pieces from contacting the bottom plate 21 and the frame 20 as the aluminum rod moves forward, and to prevent the aluminum rod oxide layer from adhering to the bottom plate 21 and the frame 20.

[0060] The annular pushing plate 40 is movably sleeved on the annular cutting tool 30. A plurality of first notches 42 and a plurality of second notches 43 are provided on the inner peripheral edge of the annular pushing plate 40. The plurality of first notches 42 are circumferentially spaced apart around the axis of the annular pushing plate 40, and the first notches 42 are arranged in one-to-one correspondence with the cutting tools 32. In the moving direction of the annular pushing plate 40, each first notch 42 is directly opposite to the corresponding cutting tool 32, so that each cutting tool 32 can pass through the annular pushing plate 40 through the corresponding first notch 42 when the annular pushing plate 40 moves.

[0061] A plurality of second notches 43 are circumferentially spaced around the axis of the annular pushing plate 40. The first notch 42 and the second notches 43 are alternately arranged along the circumferential direction of the annular pushing plate 40. The second notches 43 are arranged in one-to-one correspondence with the stoppers 33. In the moving direction of the annular pushing plate 40, each second notch 43 is directly opposite to the corresponding stopper 33, so that when the annular pushing plate 40 moves, each stopper 33 can pass through the corresponding second notch 43 and pass through the annular pushing plate 40. In this way, when the annular pushing plate 40 moves, the tool 32 and the stoppers 33 do not block the annular pushing plate 40, and it also makes the cooperation between the annular pushing plate 40 and the annular tool 30 tight, so that the annular pushing plate 40 can remove the aluminum rod oxide layer adhered to the annular tool 30 relatively cleanly.

[0062] One surface of each stopper 33 facing the pushing member 60 is an arc-shaped concave surface 331. In this way, the aluminum rod oxide layer divided into small pieces by the tool 32 will be blocked and guided by the arc-shaped concave surface 331 and rolled up when moving forward with the aluminum rod.

[0063] A support plate 13 is rotatably arranged in the blanking port 11. A motor 14 for driving the support plate 13 to rotate is arranged on the base 10. An installation groove 15 is arranged on the side wall of the blanking port 11. A pressing plate 16 and a hydraulic push rod 17 for driving the pressing plate 16 to move horizontally are arranged in the installation groove 15. The pressing plate 16 is arranged vertically.

[0064] When the annular pushing plate 40 pushes the aluminum rod oxide layer adhered to the annular tool 30 into the blanking port 11, the support plate 13 is arranged horizontally, and the support plate 13 blocks the lower end of the blanking port 11. The aluminum rod oxide layer falls onto the support plate 13. These aluminum rod oxide layers are all small pieces and they are all wound into a roll shape under the guidance of the arc-shaped concave surface 331 of the stopper 33. At this time, the hydraulic push rod 17 drives the pressing plate 16 to move so that the pressing plate 16 pushes the aluminum rod oxide layer on the support plate 13 towards the side wall of the blanking port 11, thereby flattening the aluminum rod oxide layer on the support plate 13. Since these aluminum rod oxide layers are all small pieces and they are all wound into a roll shape under the guidance of the arc-shaped concave surface 331 of the stopper 33, after the pressing plate 16 flattens these aluminum rod oxide layers, they can be made into very small pieces, occupying a small space, so that the storage basket 12 can store as many flattened aluminum rod oxide layers as possible. Then the motor 14 drives the support plate 13 to rotate so that the support plate 13 is inclined, thereby opening the lower end of the blanking port 11, so that the flattened aluminum rod oxide layer on the support plate 13 falls into the storage basket 12.

[0065] In the circumferential direction of the annular pushing plate 40, a convex portion 41 protruding towards the direction where the pushing member 60 is located is provided between any adjacent first notch 42 and second notch 43. In this way, when the annular pushing plate 40 pushes off the aluminum rod oxide layer adhered to the annular cutter 30, the convex portion 41 moves synchronously with the annular pushing plate 40, so that the convex portion 41 can push against the aluminum rod oxide layer adhered to the annular cutter 30, making it easier for the aluminum rod oxide layer to break away from the annular cutter 30.

[0066] A bushing 22 is provided on the inner wall of the through hole of the frame 20. The inner peripheral wall of the bushing 22 is relatively smooth, so that the skinned aluminum rod can more easily pass through the through hole from within the bushing 22. The annular cutter 30 is fixedly connected to the bushing 22.

[0067] When the aluminum rod peeling device of this embodiment peels an aluminum rod, the heated aluminum rod is placed on the support base 50, and then the aluminum rod is pushed towards the annular cutter 30 by the pushing member 60. When the aluminum rod passes through the annular cutter 30, the cutting edge 311 cuts off the aluminum rod oxide layer on the outer wall of the aluminum rod. At the same time, multiple cutters 32 divide the aluminum rod oxide layer into multiple small pieces, and the small pieces of the divided aluminum rod oxide layer are wound into a roll under the guidance of the arc-shaped concave surface 331 of the stopper 33. These peeled aluminum rod oxide layers adhere to the annular cutter 30, and then the annular pushing plate 40 is moved so that the annular pushing plate 40 pushes off the small pieces of the aluminum rod oxide layer wound into a roll and adhered to the annular cutter 30. At this time, the support base 50 is in the second working position, and at this time the support base 50 does not block the material dropping port 11, so that the small pieces of the aluminum rod oxide layer wound into a roll fall into the material dropping port 11 after breaking away from the annular cutter 30. The pressing plate 16 flattens these small pieces of the aluminum rod oxide layer wound into a roll and then drops them into the storage basket 12. The skinned aluminum rod passes through the frame 20 and drops onto the loading platform 18, and then the skinned aluminum rod is placed on an inverse extrusion machine to be extruded into a seamless aluminum tube.
