Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile processing technology, and in particular to a dual-station automatic traction and clamping mechanism for aluminum alloy profile extrusion lines. Background Technology

[0002] Aluminum alloy profile extrusion is a crucial step in aluminum alloy profile processing. It's a plastic forming method that forces heated aluminum alloy billets (cast rods) into profiles using a die, and it's widely used in construction, transportation, electronics, aerospace, and other fields. This process features high efficiency, high precision, and the ability to produce complex cross-sections. The dual-station automatic traction and clamping mechanism is a key piece of equipment in the aluminum alloy profile extrusion production line, enabling efficient and continuous production. It primarily stabilizes the profiles during the extrusion process and ensures their straightness and surface quality.

[0003] The dual-station automatic traction trolley consists of two independent traction and clamping mechanisms (station A and station B) integrated on the same mobile platform. Driven by servo motors or hydraulics, it reciprocates on the track, alternately clamping, traction, and release of profiles, achieving seamless production. The clamping mechanism uses high-friction pads (such as high-temperature resistant polyurethane or ceramic) to clamp the profiles, avoiding surface damage.

[0004] Traditional clamping mechanisms typically employ servo motors or hydraulic drives to open and close, thereby clamping or releasing aluminum alloy profiles. However, the additional use of servo motors or hydraulic drives not only increases costs but also consumes energy during operation, which is detrimental to energy conservation and environmental protection. Utility Model Content

[0005] The main purpose of this invention is to provide a dual-station automatic traction and clamping mechanism for aluminum alloy profile extrusion lines, so as to solve the problems raised in related technologies.

[0006] To achieve the above objectives, according to one aspect of this utility model, a dual-station automatic traction and clamping mechanism for aluminum alloy profile extrusion lines is provided, including a traction trolley, a left clamping part, and a right clamping part. The left clamping part and the right clamping part are arranged crosswise on the traction trolley and can rotate relative to the traction trolley. When not subjected to external force, the left clamping part and the right clamping part are in an open state, allowing aluminum alloy profiles to be placed between them. After the aluminum alloy profiles are placed between them, the left clamping part and the right clamping part are pressed downwards, causing the left clamping part and the right clamping part to rotate towards each other and close, thus clamping the aluminum alloy profiles.

[0007] Furthermore, both the left and right clamping parts are composed of several clamping claws, and the bottom of each clamping claw is provided with a rotating block. The clamping claw rotates relative to the traction trolley through the rotating block.

[0008] Furthermore, the clamping teeth include a main connecting plate, one end of which is fixedly connected to a lower pressure plate, and the other end of which is fixedly connected to a clamping plate. The main connecting plate, the lower pressure plate, and the clamping plate are connected to form arc-shaped clamping teeth for clamping aluminum alloy profiles.

[0009] Furthermore, the upper surface of the main connecting plate is fixed with several protrusions to increase the friction coefficient of the main connecting plate, the upper surface of the lower pressure plate is fixed with several inclined blocks to reduce the friction coefficient of the lower pressure plate, and the inner surface of the clamping plate is fixed with several blocking blocks to restrict the upward movement of the aluminum alloy profile.

[0010] Furthermore, a spring is provided at the upper end of the outer surface of the main connecting plate, the top end of the spring being rotatably connected to the main connecting plate, and the bottom end being rotatably connected to the traction trolley.

[0011] Furthermore, the rotating block is arc-shaped, with the protruding part of the arc facing downwards and rotatably connected to the traction trolley. The upper end of the rotating block is fixedly connected to the main connecting plate.

[0012] Furthermore, the bottom of the traction trolley is equipped with several rollers that rotate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention clamps aluminum alloy profiles by using a cross-shaped left and right clamping part mounted on the top of a traction trolley. When the aluminum alloy profile is placed in, the lower pressure plate is pressed down, causing the clamping plates on both sides to rotate inward and clamp the aluminum alloy profile. When the aluminum alloy profile is lifted upward, the spring returns, pulling the clamping plates outward and releasing the aluminum alloy profile. This method eliminates the need for an additional servo motor or hydraulic drive to clamp and release the aluminum alloy profile, reducing costs and energy consumption, thus promoting energy conservation and environmental protection.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] This embodiment provides a dual-station automatic traction and clamping mechanism for aluminum alloy profile extrusion lines, such as... Figure 1 As shown, the device includes a traction trolley 1, a left clamping part 4, and a right clamping part 5. The left clamping part 4 and the right clamping part 5 are arranged crosswise on the traction trolley 1 and can rotate relative to the traction trolley 1. When not subjected to external force, the left clamping part 4 and the right clamping part 5 are in an open state under the tension of their respective springs 67, allowing the aluminum alloy profile 3 to be placed between them. After the aluminum alloy profile 3 is placed between them, the lower pressure plate 62 of the left clamping part 4 and the right clamping part 5 is pressed down, causing the left clamping part 4 and the right clamping part 5 to rotate towards each other and close, clamping the aluminum alloy profile 3.

[0018] Both the left clamping part 4 and the right clamping part 5 are composed of several clamping teeth 6, which are arranged in a straight line on the top of the traction trolley 1. The clamping teeth 6 are independent of each other, and damage to one will not affect the operation of the other clamping teeth 6. A rotating block 7 is provided at the bottom of each clamping tooth 6, allowing the clamping tooth 6 to rotate relative to the traction trolley 1. The rotating block 7 is arc-shaped, with its protruding part facing downwards, and is rotatably connected to the traction trolley 1. The upper end of the rotating block 7 is fixedly connected to the main connecting plate 61.

[0019] like Figure 4 As shown, the clamping jaws 6 include a main connecting plate 61, one end of which is fixedly connected to a lower pressure plate 62, and the other end is fixedly connected to a clamping plate 63. The main connecting plate 61, the lower pressure plate 62, and the clamping plate 63 are connected to form arc-shaped clamping teeth for clamping the aluminum alloy profile 3. A spring 67 is provided on the upper end of the outer surface of the main connecting plate 61. The top end of the spring 67 is rotatably connected to the main connecting plate 61, and the bottom end is rotatably connected to the traction trolley 1. When there is no external force, the lower pressure plate 62 is located inside the clamping plate 63, ensuring that the aluminum alloy profile 3 can be smoothly placed between the left clamping part 4 and the right clamping part 5, and contacts the lower pressure plate 62 first.

[0020] In its natural state, spring 67 pulls clamping plate 63 close to traction trolley 1, lower pressure plate 62 tilts up, and clamping claws 6 of left clamping part 4 and right clamping part 5 open, as... Figure 3 As shown, aluminum alloy profile 3 can be inserted. After aluminum alloy profile 3 contacts the lower pressure plate 62 and is pressed downward, the lower pressure plate 62 rotates downward with the rotating block 7, while the main connecting plate 61 drives the clamping plate 63 to rotate upward, and the spring 67 is stretched. When the lower pressure plate 62 rotates to the lowest position, the clamping plate 63 rotates to the highest position, as shown. Figure 2 As shown, the aluminum alloy profile 3 is clamped to prevent external impact, causing the aluminum alloy profile 3 to detach from the traction trolley 1.

[0021] When the aluminum alloy profile 3 is removed, the robotic arm clamps the parts of the aluminum alloy profile 3 exposed at both ends of the left clamping part 4 and the right clamping part 5 and lifts them upwards, so that the aluminum alloy profile 3 no longer presses against the lower pressure plate 62. The spring 67 rebounds, pulling the clamping plate 63 to rotate outwards and close to the traction trolley 1. The clamping plate 63 drives the lower pressure plate 62 to rotate synchronously through the main connecting plate 61. The lower pressure plate 62 tilts up and returns to its original shape. Figure 3 As shown.

[0022] To increase the friction between the main connecting plate 61 and the aluminum alloy profile 3, several protrusions 64 are fixedly provided on the upper surface of the main connecting plate 61. The protrusions 64 are made of rubber, are soft and elastic, and are used to increase the friction coefficient of the main connecting plate 61 while preventing the main connecting plate 61 from damaging the aluminum alloy profile 3. Several inclined blocks 65 are fixedly provided on the upper surface of the lower pressure plate 62. The inclined blocks 65 are tilted downward and are made of a soft polymer with a low coefficient of friction. They are used to reduce the friction between the lower pressure plate 62 and the aluminum alloy profile 3, making it easier for the aluminum alloy profile 3 to slide down the lower pressure plate 62. Several blocking blocks 66 are fixedly provided on the inner surface of the clamping plate 63. The blocking blocks 66 are made of rubber, are soft and elastic, and are used to increase the friction between the main connecting plate 61 and the aluminum alloy profile 3 while preventing the clamping plate 63 from damaging the aluminum alloy profile 3. The blocking blocks 66 are all tilted downward, pressing against the aluminum alloy profile 3 to prevent the aluminum alloy profile 3 from moving upward and to enhance the clamping force of the clamping plate 63.

[0023] The bottom of the traction trolley 1 is equipped with several rollers 2 that rotate. The traction trolley 1 is equipped with a motor for driving the rollers 2 to rotate. When the rollers 2 rotate, they drive the traction trolley 1 to move and transport the aluminum alloy profiles 3.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
