Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profiles, in particular to a polishing device for an aluminum profile extrusion die. Background Art

[0002] Aluminum profile refers to aluminum alloy profile, which is mainly used in the construction industry and industrial industry. It has the characteristics of high corrosion resistance, excellent electrical conductivity, high thermal conductivity and strong plasticity. The use of aluminum profile is very wide, including assembly lines, guide rail profiles, U-shaped groove profiles, guardrail profiles, fence profile frames and the like. Aluminum profiles are divided into two specifications: national standard and European standard. Relatively speaking, the market share of national standard is higher. There are many types of industrial aluminum profiles on the market, so in the process of manufacturing aluminum profiles, different types of aluminum profiles have very different surface treatment methods. Different aluminum profiles have different surface treatment methods. For example, the surface of frosted profile is very delicate and soft. In the process of manufacturing aluminum profiles, the aluminum profile needs to be polished and ground. There are different ways of polishing, including manual polishing, mechanical polishing, chemical polishing, electrolytic polishing, ultrasonic polishing and so on.

[0003] However, the prior art still has the following problems:

[0004] First of all, the current frosted profiles must overcome the uneven surface sand grains and need to be properly polished. Manual polishing is time-consuming, labor-intensive, and inefficient. In addition, it is impossible to fix the aluminum profile while polishing aluminum profiles of different sizes, and it is impossible to locate and measure the midpoint of aluminum profiles that require special processing requirements.

[0005] Secondly, most grinding devices have a single fixed grinding method and a small grinding area. They cannot perform repeated grinding operations on the end faces of aluminum profiles at locations with higher defects. The grinding accuracy is low and the effect is poor, which increases the cost and time of grinding.

[0006] In view of the above problems, the inventor proposes a polishing device for an aluminum profile extrusion die to solve the above problems. Utility Model Content

[0020] By adopting the above technical solution, the extruded aluminum profile is conveyed to the bottom of the polishing device 5 through the conveyor belt 6, and the first motor 55 is started. The output end of the first motor 55 drives the threaded rod 54 to rotate, thereby driving the clamping plate 53 to move horizontally on the outer surface of the fixed plate 51 through the slide groove 52. The second motors 531 at both ends of the clamping plate 53 and the four second motors 531 at the top of the two fixed plates 511 are started together, thereby driving the four grinding heads 58 to rotate and grind. Through the movement of the clamping plate 53, the grinding heads 58 at both ends of the clamping plate 53 clamp the two ends of the aluminum profile. At the same time, the two end surfaces are polished through four fixing plates 511. The first connecting rod 56 connected to the clamping plate 53 and the second connecting rod 57 connected to the third rotating shaft 571 are rotatably connected through the second rotating shaft 562. The third rotating shaft 571, the second rotating shaft 562, and the first rotating shaft 561 form an isosceles triangle. Therefore, when the clamping plate 53 clamps aluminum plates of different widths, the second rotating shaft 562 is located at the midpoint of the third rotating shaft 571 and the first rotating shaft 561. The polishing device 5 adjusts the height through the telescopic rod 3 at the lower end of the connecting plate 2, thereby achieving the purpose of central clamping and polishing.

[0025] The inner surfaces of the two limiting plates 12 are slidably fitted with both ends of the sliding frame 41, and the sliding frame 41 is rectangular.

[0030] By adopting the above technical solution, it plays a role in facilitating the fixing of two of the second motors 531.

[0031] Embodiment 2: As Figure 3As shown, the circulation mechanism 4 includes a sliding frame 41, and racks 42 are fixedly provided on the inner walls of both sides of the sliding frame 41. A third motor 43 is fixedly provided on the outer surface of one end of the support frame 1. The output end of the third motor 43 passes through the support frame 1 and is fixedly connected to a rotating plate 44. Four rotating pins 45 are fixedly provided on the end of the rotating plate 44 facing the rack 42. The four rotating pins 45 are meshed and connected with the rack 42. The third motor 43 is started, and the output end of the third motor 43 passes through the support frame 1 to rotate the rotating plate 44 clockwise, so that the four rotating pins 45 in the rotating plate 44 pass through the tooth grooves of the rack 42 at the lower end in sequence. The rotational force causes the rotating pin 45 to drive the sliding frame 41 to move horizontally to the left. When the rotating pin 45 no longer passes through the rack 42 at the lower end, the rotating pin 45 is connected to the upper rack 42 by rotation. The rotational force causes the rotating pin 45 to pass through the tooth groove of the upper rack 42, thereby causing the rotating pin 45 to move horizontally to the right, thereby driving the circulating mechanism 4 to reciprocate between the two limit plates 12, so that the connecting plate 2 slides synchronously through the pulley 21 between the slide rails 11, thereby driving the polishing device 5 to perform repeated grinding, thereby achieving the purpose of reciprocating grinding and polishing.

[0032] By adopting the above technical solution, the structure of the entire device is made more reasonable.

[0033] The two racks 42 are distributed in a mirror image, the four rotating pins 45 and the rotating plate 44 are both circular, and the four rotating pins 45 are distributed in a ring array on one side of one end of the rotating plate 44 .

[0034] The above technical solution is adopted to facilitate the four rotating pins 45 to drive the sliding frame 41 to realize reciprocating motion through the upper and lower racks 42 and the rotation force.

[0035] Working principle: The extruded aluminum profile is conveyed to the bottom of the polishing device 5 via the conveyor belt 6, and the first motor 55 is started. The output end of the first motor 55 drives the threaded rod 54 to rotate, thereby driving the clamping plate 53 to move horizontally on the outer surface of the fixed plate 51 through the slide groove 52. The second motors 531 at both ends of the clamping plate 53 and the four second motors 531 at the top of the two fixed plates 511 are started together, thereby driving the four grinding heads 58 to rotate and grind. The movement of the clamping plate 53 makes the clamping plate 5 The grinding heads 58 at both ends clamp the two ends of the aluminum profile, and at the same time, the two end faces are ground through the four fixing plates 511. The first connecting rod 56 connected to the clamping plate 53 and the second connecting rod 57 connected to the third rotating shaft 571 are rotatably connected through the second rotating shaft 562. The third rotating shaft 571, the second rotating shaft 562, and the first rotating shaft 561 form an isosceles triangle. Therefore, when the clamping plate 53 clamps aluminum profiles of different widths, the second rotating shaft 562 is located between the third rotating shaft 571 and the first rotating shaft 561. The polishing device 5 is at the midpoint position of a rotating shaft 561, and the polishing device 5 is height-adjusted by the telescopic rod 3 at the lower end of the connecting plate 2, so as to achieve the purpose of centering clamping and grinding. The two ends of the connecting plate 2 are respectively connected to the pulley 21 and the circulating mechanism 4, and the third motor 43 is started. The output end of the third motor 43 passes through the supporting frame 1 and rotates the rotating plate 44 clockwise, so that the four rotating pins 45 in the rotating plate 44 pass through the tooth grooves of the rack 42 at the lower end in sequence, and the rotation force causes the rotating pin 45 to drive the sliding frame 41 to move horizontally to the left. When the rotating pin 45 no longer passes through the rack 42 at the lower end, the rotating pin 45 is connected to the upper rack 42 by rotation, and the rotation force causes the rotating pin 45 to pass through the tooth grooves of the upper rack 42, so that the rotating pin 45 moves horizontally to the right, thereby driving the circulating mechanism 4 to reciprocate between the two limit plates 12, so that the connecting plate 2 slides synchronously through the pulley 21 between the slide rails 11, thereby driving the polishing device 5 to perform repeated grinding, thereby achieving the purpose of reciprocating grinding and polishing.
