Description

Technical Field

[0001] This invention relates to the field of aluminum profile extrusion technology, and more specifically, to an extrusion apparatus for processing aluminum profiles. Background Technology

[0002] Existing aluminum profile extrusion equipment generally includes a heating device, an extrusion press, and a conveying and cutting device. The production process is as follows: the heating device heats the aluminum billet, cuts it into small segments, and then conveys the cut aluminum billet to the extrusion station of the extrusion press to be extruded into long strip profiles. The extruded profiles are then conveyed and cut by the conveying and cutting device to form finished profiles.

[0003] However, traditional aluminum profile extrusion equipment lacks a structure to adjust the aluminum billet when feeding it into the extrusion press. In other words, the existing technology lacks a structure to center-align the aluminum billet with the extrusion press. Consequently, it cannot be guaranteed that the aluminum billet will be centered with the center of the extrusion press when it enters the extrusion press, resulting in misalignment due to the offset of the aluminum billet's center position. Meanwhile, the existing technology does not have the effect of continuously cleaning the outer wall of the aluminum billet. That is, before the aluminum billet enters the extrusion equipment, the impurities adsorbed on the outer surface of the aluminum billet will affect the extrusion effect of the aluminum billet and affect the final finished profile.

[0004] To address the aforementioned technical shortcomings, a solution is provided. Summary of the Invention

[0005] The present invention provides an extrusion apparatus for aluminum profile processing to solve the technical problems mentioned in the background art, namely, the lack of a structure for extrusion equipment capable of center-aligning aluminum billets and the lack of a continuous cleaning effect on the outer wall of aluminum billets.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an extrusion device for aluminum profile processing, comprising a feeding platform, an inlet provided inside the feeding platform, an extruder body provided on one side of the feeding platform, a ring clamping mechanism and a pressure regulating mechanism provided on one side of the feeding platform, the ring clamping mechanism and the pressure regulating mechanism can convert the pressure of the aluminum billet entering into a ring-shaped clamping pressure on one side of the inlet, so that the ring clamping can uniformly and synchronously extrude and clamp the outer surface of the aluminum billet, pushing the center of the aluminum billet to align, and a sweeping mechanism provided on one side of the feeding platform, the sweeping mechanism can continuously clean the surface of the aluminum billet when the aluminum billet enters the inlet and moves forward.

[0007] In a preferred embodiment, the ring clamping mechanism includes two fixed locking plates fixedly installed on one side of the feeding platform. The two fixed locking plates are arranged symmetrically to each other. A ring frame is rotatably installed on one side of both fixed locking plates. The ring frame is arranged in a vertical state and is centrally aligned with the feeding port.

[0008] In a preferred embodiment, a plurality of retaining plates are fixedly installed on the inner wall of the ring frame. The plurality of retaining plates are arranged in a ring at equal intervals on the inner wall of the ring frame. A push spring is fixedly installed on one side of each of the plurality of retaining plates. A sliding push plate is fixedly installed on one side of each of the plurality of push springs. The plurality of sliding push plates are slidably installed on the inner wall of the ring frame.

[0009] In a preferred embodiment, one side of each of the plurality of sliding push plates is hinged to an extrusion plate, the plurality of extrusion plates are inclined upwards, and the top of each of the plurality of extrusion plates is hinged to a positioning plate. The plurality of positioning plates are arranged in a ring at equal intervals around the inner wall of the ring frame, and the other end of the plurality of positioning plates is rotatably mounted with a rotating shaft, the rotating shaft being fixedly mounted on the outer wall of the feeding table.

[0010] In a preferred embodiment, the pressure regulating mechanism includes a pressure plate slidably mounted on the outer wall of the feeding platform. The pressure plate is vertically arranged, with its top sloped. A support spring is fixedly mounted on the bottom of the pressure plate, and the support spring is fixedly mounted on the outer wall of the feeding platform.

[0011] In a preferred embodiment, a toothed plate is fixedly installed on one outer wall of the pressure plate, a gear is meshed on one side of the toothed plate, the gear is rotatably installed on the outer wall of the feeding table, the width of the toothed plate is smaller than the width of the gear, a toothed ring is meshed at the bottom of the gear, the toothed ring is fixedly installed on the outer wall of the ring frame, and the width of the toothed ring is smaller than the width of the gear.

[0012] In a preferred embodiment, the rotating sweeping mechanism includes a rotating rod rotatably mounted on the inner wall of the positioning plate, a rubber roller fixedly mounted on the outer wall of the rotating rod, the rubber roller being located at the center of the positioning plate, and the outer wall of the rubber roller penetrating through the outer wall of the positioning plate.

[0013] In a preferred embodiment, a first pulley is fixedly installed on one side of the rotating rod, a timing belt is rotatably installed on the outer wall of the first pulley, a second pulley is rotatably installed on one side of the timing belt, the second pulley is fixedly installed on the outer wall of the positioning plate, and a rotating brush is fixedly installed on one side of the outer wall of the second pulley, the rotating brush being arranged parallel to the positioning plate.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention, by setting up a ring clamping mechanism and a constant pressure mechanism, firstly, when the aluminum billet moves forward, the pressing plate driven by the extrusion causes the ring frame to rotate. The pressure generated by the rotation of the ring frame causes multiple clamping plates to deflect. The multiple clamping plates converge towards the center position in a ring structure and clamp the outer surface of the aluminum billet synchronously. This ensures that the outer surface of the aluminum billet is uniformly subjected to pressure and aligned with the center position of the extrusion press body, avoiding the problem of misalignment caused by the center position of the aluminum billet shifting.

[0015] 2. The rotating sweeping mechanism is set up at the same time. When the clamping plate holds and adheres to the outer wall of the aluminum billet, the forward-moving aluminum billet squeezes and pushes the rubber roller to rotate. That is, the rubber roller drives the rotating sweeping brush on the outer wall of the clamping plate to rotate synchronously. At this time, the rotating sweeping brush contacts the outer wall of the aluminum billet, thereby continuously cleaning the outer wall of the aluminum billet and removing the impurities adsorbed on the outer surface of the aluminum billet.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0025] Existing technologies lack structures for extrusion presses capable of center-aligning aluminum billets. Consequently, when the aluminum billet enters the extrusion press, it cannot be guaranteed that its center will be directly aligned with the center of the extrusion press, resulting in misalignment due to center displacement of the aluminum billet. To address this issue, the following technical solution is proposed: Refer to the instruction manual appendix Figures 1-7 An extrusion apparatus for processing aluminum profiles, such as Figure 1 and Figure 2 As shown, the device includes a feeding platform 1, with a feeding port 2 inside the feeding platform 1. An extruder body 3 is located on one side of the feeding platform 1. A ring clamping mechanism 4 and a constant pressure mechanism 5 are located on one side of the feeding platform 1. The ring clamping mechanism 4 and the constant pressure mechanism 5 can convert the pressure of the aluminum billet entering into the feeding port 2 into a ring-shaped clamping pressure, so that the ring clamping can uniformly and synchronously extrude and clamp the outer surface of the aluminum billet, pushing the center of the aluminum billet to align. A rotating sweeping mechanism 6 is located on one side of the feeding platform 1. The rotating sweeping mechanism 6 can continuously clean the surface of the aluminum billet when the aluminum billet enters the feeding port 2 and moves forward.

[0026] like Figure 1 and Figure 2 As shown, the ring clamping mechanism 4 includes two fixed locking plates 41 fixedly installed on one side of the feeding platform 1. The two fixed locking plates 41 are arranged symmetrically to each other. A ring frame 42 is rotatably installed on one side of the two fixed locking plates 41. The ring frame 42 is arranged in a vertical state and is aligned with the center of the feeding port 2. The ring frame 42 can align the aluminum billet located in the center with the center position of the feed inlet 2.

[0027] like Figure 3 and Figure 4 As shown, multiple retaining plates 43 are fixedly installed on the inner wall of the ring frame 42. The multiple retaining plates 43 are arranged in a ring at equal intervals on the inner wall of the ring frame 42. A push spring 44 is fixedly installed on one side of each of the multiple retaining plates 43. A sliding push plate 45 is fixedly installed on one side of each of the multiple push springs 44. The multiple sliding push plates 45 are slidably installed on the inner wall of the ring frame 42. When the ring frame 42 rotates, it drives multiple retaining plates 43 to rotate synchronously. The multiple retaining plates 43 squeeze multiple push springs 44 and push the sliding push plate 45.

[0028] like Figure 3 and Figure 4 As shown, a plurality of sliding push plates 45 are hinged to one side of an extrusion plate 46. The plurality of extrusion plates 46 are inclined upwards. A locking plate 47 is hinged to the top of each of the plurality of extrusion plates 46. The plurality of locking plates 47 are arranged in a ring at equal intervals around the inner wall of the ring frame 42. A rotating shaft 48 is rotatably installed at the other end of the plurality of locking plates 47. The rotating shaft 48 is fixedly installed on the outer wall of the feeding table 1. Multiple sliding push plates 45 press and push the extrusion plate 46, and the extrusion plate 46 causes multiple clamping plates 47 to be deflected under the limit of the rotating shaft 48. Then, the multiple clamping plates 47 synchronously gather towards the center position to clamp the outer surface of the aluminum billet.

[0029] like Figure 2 and Figure 5 As shown, the constant pressure mechanism 5 includes a pressure plate 51 that is slidably installed on the outer wall of the feeding table 1. The pressure plate 51 is set in a vertical state, the top of the pressure plate 51 is set in a sloping state, and a support spring 52 is fixedly installed at the bottom of the pressure plate 51. The support spring 52 is fixedly installed on the outer wall of the feeding table 1. When the aluminum billet moves forward, it can approach and push the pressure plate 51. Then the pressure plate 51 passes through the inclined surface and is squeezed and moves downward. The downward movement of the pressure plate 51 compresses the support spring 52.

[0030] like Figure 5 As shown, a toothed plate 53 is fixedly installed on one side of the outer wall of the pressure plate 51, and a gear 54 is meshed on one side of the toothed plate 53. The gear 54 is rotatably installed on the outer wall of the feed table 1. The width of the toothed plate 53 is smaller than the width of the gear 54. A toothed ring 55 is meshed at the bottom of the gear 54. The toothed ring 55 is fixedly installed on the outer wall of the ring frame 42. The width of the toothed ring 55 is smaller than the width of the gear 54. The downward movement of the pressure plate 51 causes the toothed plate 53 to move downward simultaneously and pushes the gear 54 to rotate. The gear 54 then drives the toothed ring 55 to rotate, that is, the position of the deflection of the toothed ring 55 drives the ring frame 42 to rotate.

[0031] In specific implementation, when the aluminum billet moves forward, it can approach and push the pressure plate 51. The pressure plate 51 then moves downward through the inclined surface and is squeezed. The downward movement of the pressure plate 51 compresses the support spring 52. The downward movement of the pressure plate 51 drives the toothed plate 53 to move downward simultaneously and pushes the gear 54 to rotate. The gear 54 drives the toothed ring 55 to rotate. That is, the position of the deflection of the toothed ring 55 drives the ring frame 42 to rotate. When the ring frame 42 rotates, it drives multiple fixing plates 43 to rotate synchronously. The multiple fixing plates 43 squeeze multiple extrusion springs 44 and push the sliding push plate 45. The multiple sliding push plates 45 squeeze and push the extrusion strip plate 46. The extrusion strip plate 46 causes multiple clamping plates 47 to be deflected under the limit of the rotating shaft 48. Then, the multiple clamping plates 47 synchronously converge towards the center position to clamp the outer surface of the aluminum billet. After the multiple clamping plates 47 clamp the aluminum billet, the pressure of the fixing plates 43 squeezed by the rotating ring frame 42 can be directly pushed out through the multiple clamping plates 47, improving the extrusion clamping effect. Moreover, the multiple clamping plates 47 squeeze the aluminum billet together in a ring structure, so that the outer surface of the aluminum billet is uniformly subjected to pressure and aligned with the center position of the extrusion machine body 3, avoiding the problem of misalignment caused by the center position of the aluminum billet shifting. Example 2

[0032] Existing technologies lack the ability to continuously clean the outer wall of aluminum billets. This means that impurities adsorbed on the outer surface of the aluminum billet before it enters the extrusion press can affect the extrusion effect and ultimately the final product profile. To address this problem, the following technical solution is proposed: like Figure 6 and Figure 7 As shown, the rotary sweeping mechanism 6 includes a rotating rod 61 rotatably installed on the inner wall of the positioning plate 47, and a rubber roller 62 fixedly installed on the outer wall of the rotating rod 61. The rubber roller 62 is located at the center of the positioning plate 47, and the outer wall of the rubber roller 62 penetrates the outer wall of the positioning plate 47. When the clamping plate 47 holds and adheres to the outer wall of the aluminum billet, the forward-moving aluminum billet squeezes and pushes the rubber roller 62 to rotate, that is, the rubber roller 62 drives the rotating rod 61 to rotate.

[0033] like Figure 6 and Figure 7 As shown, a first pulley 63 is fixedly installed on one side of the rotating rod 61, a synchronous belt 64 is rotatably installed on the outer wall of the first pulley 63, a second pulley 65 is rotatably installed on one side of the synchronous belt 64, the second pulley 65 is fixedly installed on the outer wall of the positioning plate 47, and a rotating brush 66 is fixedly installed on one side of the outer wall of the second pulley 65. The rotating brush 66 and the positioning plate 47 are arranged parallel to each other. The rotating rod 61 drives the first pulley 63 to rotate synchronously. The first pulley 63 then drives the second pulley 65 to rotate via the synchronous belt 64. The second pulley 65 drives the rotating brush 66 to rotate synchronously. At this time, the rotating brush 66 contacts the outer wall of the aluminum billet, thereby continuously cleaning the outer wall of the aluminum billet.

[0034] In practice, when the clamping plate 47 holds and adheres to the outer wall of the aluminum billet, the forward-moving aluminum billet squeezes and pushes the rubber roller 62 to rotate. That is, the rubber roller 62 drives the rotating rod 61 to rotate, and the rotating rod 61 drives the first pulley 63 to rotate synchronously. The first pulley 63 then drives the second pulley 65 to rotate through the synchronous belt 64. The second pulley 65 drives the rotating brush 66 to rotate synchronously. At this time, the rotating brush 66 contacts the outer wall of the aluminum billet, thereby continuously cleaning the outer wall of the aluminum billet and removing the impurities adsorbed on the outer surface of the aluminum billet.
