Description

Technical Field

[0001] This invention relates to the field of extrusion molding equipment technology, and in particular to an extrusion molding equipment for processing aluminum alloy profiles. Background Technology

[0002] Extrusion forming equipment for aluminum alloy profile processing is mainly used to extrude aluminum alloy bars into profiles of specific shapes, especially for the production of H-shaped aluminum alloy profiles. This equipment typically consists of the following parts: an extruder, a die, a heating system, a cooling system, a drawing device, and a cutting system. After the aluminum alloy bar is heated to a certain temperature by the heating system, it enters the extruder and, under high temperature and pressure, passes through a die with an H-shaped cross-section, undergoing plastic deformation to form the desired aluminum alloy profile. In this process, the forming of the aluminum alloy profile involves forcibly pushing the metal material into the die, thereby forming a predetermined cross-section in the shape of the die.

[0003] Throughout the production process, the extrusion molding unit ensures the dimensional accuracy, surface quality, and stable mechanical properties of the aluminum alloy profiles by precisely controlling parameters such as temperature, pressure, die design, and extrusion speed. Finally, the extruded aluminum alloy profiles undergo cooling and drawing processes to facilitate subsequent cutting and further processing, ensuring the products meet the requirements of various applications.

[0004] However, existing technologies still face some technical bottlenecks in the extrusion process of aluminum alloy profiles. Firstly, aluminum alloy bars typically cannot undergo effective pre-forming treatment before entering the extruder. Pre-forming treatments, such as pre-extrusion forming of the bars, can effectively improve the quality of the extruded product and reduce defects. Aluminum alloy bars that have not undergone pre-treatment may develop cracks and porosity during extrusion, affecting the mechanical properties and appearance of the final product.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1, as Figure 1As shown, an extrusion forming device for processing aluminum alloy profiles includes a mounting platform 1. Three support legs 2 are fixedly connected to the lower left and lower right sides of the mounting platform 1. A hydraulic cylinder 3 is fixedly connected to the middle of the upper rear side of the mounting platform 1. An extrusion assembly 4 is fixedly connected to the middle of the upper side of the mounting platform 1. A scrap material removal assembly 5 is fixedly installed at the front end of the mounting platform 1. A dividing assembly 6 is fixedly installed on the front side of the outer surface of the scrap material removal assembly 5. A receiving assembly 7 is fixedly installed at the lower front end of the mounting platform 1.

[0033] In this process, the heated aluminum alloy bar is placed on the surface of the extrusion assembly 4. Then, by controlling the hydraulic cylinder 3, the hydraulic cylinder 3 pushes the structure inside the extrusion assembly 4 to push the aluminum alloy bar forward. As the aluminum alloy bar moves forward inside the extrusion assembly 4, the extrusion assembly 4 can pre-cut the aluminum alloy bar into the shape to be extruded. The extrusion assembly 4 and the scrap removal assembly 5 work together to cut the scrap in multiple directions, so as to facilitate the subsequent recycling and reuse of the scrap. At the same time, the dividing assembly 6 can assist in guiding the extruded finished material. When the scrap is pushed out from the scrap removal assembly 5, it can fall onto the surface of the receiving assembly 7 and then into the inner cavity of the receiving assembly 7 for storage, so as to facilitate the unified processing of the scrap in the future.

[0034] The device used in the process of placing the heated aluminum alloy bar on the surface of the extrusion assembly 4 is a conventional setup in the prior art. In this solution, it is only necessary to heat the aluminum alloy bar and grab and place the bar on the surface of the extrusion assembly 4. The specific installation method, circuit connection method and control method are all conventional designs and can be adjusted according to actual production needs. Therefore, this solution will not elaborate on them in detail.

[0035] Example 2, as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, the extrusion assembly 4 includes three support plates 41 fixedly connected to the left and right sides of the upper middle part of the mounting platform 1. An arc-shaped plate 42 is fixedly connected to the upper ends of the three support plates 41 on the left and the three support plates 41 on the right. An extrusion block 43 is fixedly connected to the output end of the hydraulic cylinder 3 through a piston rod. Several support plates 44 are fixedly connected to the middle of the front side of the upper end of the mounting platform 1. A feed cylinder 45 is fixedly connected to the upper ends of the several support plates 44. The feed cylinder 45 is located in front of the arc-shaped plate 42. A material distribution assembly 46 is fixedly installed in the inner cavity of the feed cylinder 45.

[0036] Furthermore, the inner diameter of the feed cylinder 45 is equal to the inner diameter of the arc plate 42, and the rear end of the feed cylinder 45 is in contact with the front end of the arc plate 42.

[0037] Furthermore, the material distribution assembly 46 includes an H-shaped plate 461 fixedly connected to the front side of the inner surface of the feed cylinder 45. An inner liner 462 is fixedly connected to the front side of the top wall and the front side of the bottom wall of the H-shaped plate 461. Support rods 463 are fixedly connected to the corners of the inner surface of the inner liner 462. A flow divider 464 is fixedly connected to one end of the four support rods 463 that are close to each other. A guide block 465 is fixedly connected to the front end of the flow divider 464.

[0038] Furthermore, the rear edge of the H-shaped plate 461 is inclined.

[0039] Furthermore, the scrap removal assembly 5 includes a mounting plate 51 fixedly connected to the front end of the mounting platform 1. Rectangular blocks 52 are fixedly connected to the upper left and upper right sides of the mounting plate 51. A triangular platform 53 is fixedly connected to the lower left side of the mounting plate 51. A servo motor 54 is fixedly connected to the upper end of the triangular platform 53. A transmission rod 55 is rotatably connected to the ends of the two rectangular blocks 52 that are close to each other. Mounting grooves 56 are opened in the middle of the left side and the middle of the right side of the front end of the mounting plate 51. Threaded rods 57 are rotatably connected to the left and right walls of the inner surfaces of the two mounting grooves 56. The left and right ends of the transmission rod 55 pass through the rectangular blocks 52 on the same side and extend to the outside. The ends of the two threaded rods 57 that are far apart from each other pass through the mounting grooves 56 on the same side and extend to the outside. Pulleys 58 are fixedly connected to the outer surfaces of the transmission rods 55 and the two threaded rods 57 that are far apart from each other. The outer surfaces of the two pulleys 58 on the same side are connected by belt drive. The output end of the servo motor 54 is fixedly connected to the pulleys 58 on the same side through a coupling.

[0040] Furthermore, the mounting plate 51 has a finished product outlet 591 at the middle of its front end, and two excess material outlets 592 on the upper and lower sides of the front end of the mounting plate 51, and two excess material outlets 593 on the left and right sides of the front end of the mounting plate 51.

[0041] Furthermore, sliders 594 are slidably connected to the inner surfaces of the two mounting slots 56. The inner surfaces of the two sliders 594 are threadedly connected to the outer surfaces of the two threaded rods 57 respectively. Push plates 595 are fixedly connected to the front ends of the two sliders 594. Cutting plates 596 are fixedly connected to the ends of the two push plates 595 that are close to each other. Cutting grooves 597 are opened at the ends of the two cutting plates 596 that are close to each other.

[0042] Furthermore, the segmentation component 6 includes an H-shaped cavity plate 61 fixedly connected to the middle of the front end of the mounting plate 51, a first material distribution plate 62 fixedly connected to the middle of the upper end and the middle of the lower end of the H-shaped cavity plate 61, and a second material distribution plate 63 fixedly connected to the middle of the left end and the middle of the right end of the H-shaped cavity plate 61.

[0043] Furthermore, the receiving assembly 7 includes a connecting plate 71 fixedly connected to the lower front end of the mounting plate 51. A trapezoidal receiving box 72 is fixedly connected to the front end of the connecting plate 71. Extension blocks 73 are fixedly connected to the left and right rear ends of the trapezoidal receiving box 72. The rear ends of the two extension blocks 73 are fixedly connected to the front ends of the support legs 2 on the same side. A first material drop groove 74 is provided in the middle of the upper end of the trapezoidal receiving box 72. A second material drop groove 75 is provided on the upper left inclined surface and the upper right inclined surface of the trapezoidal receiving box 72.

[0044] During use, the heated aluminum alloy bar is first placed on the upper side of the arc plate 42. Then, by starting the hydraulic cylinder 3, the output end of the hydraulic cylinder 3 drives the extrusion block 43, which is fixedly connected to it, to move forward through the piston rod. When the extrusion block 43 moves forward, it can push the aluminum alloy bar in front of it forward. Since the front end of the arc plate 42 is in contact with the rear end of the feed cylinder 45, and the inner diameter of the feed cylinder 45 is the same as the inner diameter of the arc plate 42, the aluminum alloy bar can be pushed into the feed cylinder 45 by the extrusion block 43.

[0045] When the aluminum alloy bar is pushed into the inner cavity of the feed cylinder 45, it is continuously squeezed forward by the extrusion block 43. Because the rear edge of the H-shaped plate 461 is inclined, the front end of the aluminum alloy bar will be squeezed and cut at the rear end of the H-shaped plate 461. This causes the excess material to be squeezed forward from the upper and lower sides of the H-shaped plate 461 and the left and right sides of the inner liner plate 462. The pre-cut pre-finished material is squeezed into the inner cavity of the inner liner plate 462. Since support rods 463 are fixedly connected to the corners of the inner surface of the inner liner plate 462, and the four support rods 463 are mutually... The two ends are fixedly connected to a diversion block 464. Therefore, when the pre-finished material is squeezed forward in the inner liner plate 462, the middle of the pre-finished material will be squeezed into a hollow shape by the rear side of the diversion block 464. The outer surface of the finished material has the same shape as the cavity formed between the inner liner plate 462 and the diversion block 464. This shape is similar to a horizontally placed H-shape. When the finished material continues to move forward, since the rear end of the mounting plate 51 is in contact with the front end of the H-shaped plate 461, the finished material can enter the inner cavity of the finished material inlet 591 and then be squeezed into the inner cavity of the H-shaped cavity plate 61.

[0046] During the extrusion process, the excess material will first be extruded and moved forward from the cavity formed between the upper and lower sides of the outer surface of the H-shaped plate 461 and the feed cylinder 45, and the cavity formed between the left and right sides of the outer surface of the inner liner plate 462 and the feed cylinder 45. As the excess material is extruded forward from the inner cavity of the excess material port 1 592 and the excess material port 2 593 on the same side, since the rear end of the H-shaped cavity plate 61 is fixedly connected to the middle of the front end of the mounting plate 51, and the material distribution plate 1 62 and the material distribution plate 2 63 on the same side are located in the inner cavity of the excess material port 1 592 and the excess material port 2 593 on the same side, the extruded excess material will be extruded and cut from the middle position by the material distribution plate 1 62 and the material distribution plate 2 63.

[0047] Simultaneously, by activating the servo motor 54, the output end of the servo motor 54 drives the pulley 58 fixedly connected to it to rotate via the coupling. Since the outer surfaces of the two pulleys 58 on the same side are connected by belt drive, and under the action of the transmission rod 55, the threaded rods 57 on both sides can rotate simultaneously. When the threaded rods 57 on both sides rotate, since the sliders 594 on both sides are slidably connected to the inner surface of the mounting groove 56 on the same side, and the inner surface of the sliders 594 on the same side is threadedly connected to the outer surface of the threaded rods 57 on the same side, The sliders 594 on both sides can drive the push plates 595 fixedly connected to them to move inward simultaneously. During the process of the push plates 595 moving inward, the cutting grooves 597 opened on the outer surface of the two cutting plates 596, together with the H-shaped cavity plate 61, the first material distribution plate 62 and the second material distribution plate 63, match each other. Therefore, when the two cutting plates 596 move inward simultaneously, the excess material can be clamped off. Under the reciprocating drive of the servo motor 54, the two cutting plates 596 can reciprocate to clamp off the extruded excess material.

[0048] The remaining material after being clamped will fall from the first material drop trough 74 at the top of the trapezoidal receiving box 72 into the inner cavity of the trapezoidal receiving box 72. The remaining material on both sides will slide down along the inclined surface on the upper side of the trapezoidal receiving box 72 and fall from the second material drop trough 75 on both sides into the inner cavity of the trapezoidal receiving box 72 for storage. By storing the remaining material in a unified manner, it is convenient to recycle and reuse the remaining material in the future.

[0049] The servo motor 54 mentioned above is a conventional configuration in the prior art, and its specific working principle is as follows:

[0050] The servo motor 54 achieves reciprocating drive, which relies on the coordinated regulation of the servo driver and position control program to accurately switch between forward and reverse rotation and stroke, thus completing periodic reciprocating motion.

[0051] First, the control system sends pulse and direction signals to the servo driver. The number of pulses controls the rotation angle, the frequency adjusts the speed, and the direction signal determines whether the motor rotates forward or backward. The motor's built-in encoder collects position and speed data in real time and feeds it back to the driver to form a closed loop, eliminating errors and ensuring motion accuracy.

[0052] When the equipment is running, two limit position parameters are set in advance: after the motor runs forward to the set travel limit, the control system automatically switches the direction signal, the motor decelerates, reverses and runs in reverse; when it runs in reverse to the limit position on the other side, the reversing command is triggered again.

[0053] By combining a reducer, lead screw, rack and pinion transmission mechanism, the rotary motion of the motor can be converted into linear reciprocating motion. The driver avoids commutation shock through acceleration and deceleration buffer control, and with the continuous cyclic position logic command, it ultimately achieves stable, continuous, and adjustable speed and stroke reciprocating drive action.

[0054] Therefore, the servo motor 54 mentioned above is a conventional design in the prior art, and this solution will not elaborate on it further.

[0055] It should be noted that the specific installation method, circuit connection method, and control method of the hydraulic cylinder 3 and servo motor 54 used in this invention are all conventional designs, and will not be described in detail in this invention.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
