Description

Technical Field

[0001] This utility model relates to the field of aluminum profile traction machine technology, specifically an improved aluminum profile traction machine clamping device. Background Technology

[0002] The aluminum profile traction machine is a key piece of equipment used in the aluminum profile production process. It is mainly used to traction, guide and clamp the profile after it is extruded from the extruder, to ensure that the profile remains straight and undeformed during the traction process, and finally reaches the predetermined extrusion length.

[0003] The clamping force of the traction machine's clamping device varies at different stages of the profile's movement. In the initial stage of the profile being pulled from the extruder outlet, high-frequency vibrations or momentary shifts are prone to occur due to factors such as extrusion speed fluctuations and incomplete cooling and shaping of the profile head. High clamping force is required to ensure that the profile does not slip or twist. However, once the traction process enters a stable stage, the profile has formed a stable straight shape and its surface hardness has increased, at which point the required clamping force does not need to be too high. In existing technologies, some equipment achieves clamping force switching by manually adjusting the clamping system in stages, but the operation relies on experience and has a response delay, making it difficult to match the real-time requirements of high-speed production lines. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an improved aluminum profile traction machine clamping device to solve the technical problem that in the current technology, some equipment achieves clamping force switching by manually adjusting the clamping system in stages, but the operation depends on experience and the response is delayed.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: An improved aluminum profile traction machine clamping device is designed, comprising a slider, an upper clamping block, and an upper pressure block. A base frame is fixedly connected to the bottom of the slider. A swing rod is rotatably connected between the inner side walls of the base frame. A connecting rod is rotatably connected between the side wall of the swing rod and a pull rod via a hinge seat. The pull rod passes laterally through a through groove opened in the side wall of the pressure block. A vertical groove and a horizontal groove are opened on the inner side of the upper clamping block. A spring is fixedly connected between the pressure block and the inner wall of the vertical groove. The pull rod is laterally slidably connected inside the horizontal groove, and the pressure block is vertically slidably connected inside the vertical groove.

[0006] In this solution, when traction begins after clamping the aluminum profile, the swing arm swings due to inertia, pulling the first connecting rod and the tie rod, pushing the pressure block downward, so that the pressure block applies pressure to the surface of the aluminum profile, compensating for the total clamping force in the initial stage, ensuring that the clamping does not slip to the greatest extent, improving the stability of the clamping, realizing real-time matching of clamping force and working conditions, and greatly improving the response speed.

[0007] Preferably, the upper pressure block is fixedly connected to the bottom surface of one end of the crossbar, the other end of the crossbar is fixedly connected to the side wall surface of the slider, the slider is located on the surface of the slide rod and is slidably connected to the slide rod, the slide rod is fixedly connected between the upper and lower inner walls of the outer frame, and a limit strip is fixedly connected to the outer wall of the slide rod.

[0008] In practical applications, the slider slides up and down on the surface of the slider rod, ensuring the stability of the slider during movement. The limit bar can prevent the slider from rotating, thus preventing damage to the electric actuator rod.

[0009] Preferably, an electric actuator is fixedly connected to the top of the outer frame, and the telescopic end of the electric actuator passes through the top surface of the outer frame and is fixedly connected to the slider.

[0010] In practical applications, the electric actuator drives the slider and the upper clamping block to descend, applying a constant clamping force to the aluminum profile. This clamping force is the clamping force required for smooth traction, while the clamping force compensation at the start of operation is implemented by the pressure block.

[0011] Preferably, a lower clamping block is fixedly connected to the lower edge of the side wall of the outer frame, and the lower clamping block is located directly below the upper clamping block.

[0012] In practical applications, the lower clamping block and the upper clamping block work together to clamp the aluminum profile, and both of them are covered with anti-slip material to increase friction and facilitate clamping.

[0013] Preferably, a support frame is fixedly connected to the side wall of the base frame, and an inner clamping block is fixedly connected to the other end of the support frame. The inner clamping block is located below the upper clamping block, and a stop block is slidably connected to the inner side of the inner clamping block. A second connecting rod is rotatably connected between the stop block and the side wall of the swing arm through a hinge seat.

[0014] In practical applications, the inner clamping block can extend into the inside of the aluminum profile, and the abutment block can be raised to provide support from below, reducing the impact of the pressure block on the surface of the aluminum profile.

[0015] Preferably, a counterweight is fixedly connected to the lower end of the swing arm, and a buffer plate is fixedly connected to the inner side wall of the base frame on one side of the swing arm.

[0016] In practical applications, the counterweight can amplify the effect of inertia, causing the bottom of the pendulum to swing to the left, while the buffer plate can absorb the impact force when the pendulum returns to its original position, reducing the swaying of the pendulum and allowing it to quickly and smoothly return to its original position.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, by setting a swing arm, when the aluminum profile is clamped and traction begins, the swing arm will swing due to inertia, pulling the first connecting rod and the pull rod, pushing the pressure block downward, so that the pressure block applies pressure to the surface of the aluminum profile, compensating for the total clamping force in the initial stage, ensuring that the clamping does not slip to the greatest extent, improving the stability of the clamping, realizing real-time matching of clamping force and working conditions, eliminating the need for manual adjustment, and greatly improving the response speed.

[0019] 2. This utility model provides an inner clamping block below the lower pressure block. When the swing arm swings, it pushes the second connecting rod and the stop block, allowing the stop block to extend and contact the inner surface of the aluminum profile. This provides a simple support effect from below, reducing the impact of the pressure block's compressive stress on the aluminum profile surface and ensuring the stability and integrity of the aluminum profile during the traction process.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: See Figures 1 to 4An improved aluminum profile traction machine clamping device includes a slider 4, an upper clamping block 6, and an upper pressure block 7. A base frame 401 is fixedly connected to the bottom of the slider 4. A swing rod 9 is rotatably connected between the inner walls of the base frame 401. A counterweight 901 is fixedly connected to the lower end of the swing rod 9. A buffer plate 15 is fixedly connected to the inner wall of the base frame 401 on one side of the swing rod 9. The swing rod 9 contacts the buffer plate 15 when it is not swinging. The surface of the buffer plate 15 is provided with a buffer material, such as sponge or silicone pad, which can absorb and buffer the impact force of the swing rod 9 when it swings back and forth, avoiding hard impact that causes the swing rod 9 to swing back and forth. The swing rod 9 has the ability to rotate. When the outer frame 1 moves to the right, the swing rod 9 will swing to the left due to inertia. The counterweight 901 at its bottom can amplify this inertial effect, making the swing angle of the swing rod 9 larger and increasing the subsequent pulling distance.

[0027] Next, a connecting rod 10 is rotatably connected between the side wall of the swing rod 9 and the pull rod 8 via a hinge seat. The pull rod 8 passes laterally through the through slot 701 opened in the side wall of the pressure block 7. The inner side of the upper clamping block 6 is provided with a vertical slot 601 and a horizontal slot 602. A spring 702 is fixedly connected between the pressure block 7 and the inner wall of the vertical slot 601. The spring 702 can assist the pressure block 7 in resetting. The pull rod 8 is laterally slidably connected in the inner side of the horizontal slot 602, and the pressure block 7 is vertically slidably connected in the inner side of the vertical slot 601. When the swing rod 9 swings, its top end will move to the right, thereby pulling the connecting rod 10. The connecting rod 10 is connected to the pull rod 8, so it will pull the pull rod 8 out of the horizontal slot 602 of the upper clamping block 6. During the lateral movement of the pull rod 8, it will push the pressure block 7 to move downward. During the downward movement, it will apply pressure to the surface of the aluminum profile, compensate for the total clamping force in the initial stage, and ensure that the clamping does not slip to the greatest extent and improve the stability of the clamping.

[0028] Specifically, such as Figure 1 As shown, an electric push rod 3 is fixedly connected to the top of the outer frame 1. The telescopic end of the electric push rod 3 passes through the top surface of the outer frame 1 and is fixedly connected to the slider 4. The upper pressure block 7 is fixedly connected to the bottom surface of one end of the crossbar 5. The other end of the crossbar 5 is fixedly connected to the side wall surface of the slider 4. The slider 4 is located on the surface of the slide bar 2 and is slidably connected to the slide bar 2. The slide bar 2 is fixedly connected between the upper and lower inner walls of the outer frame 1. When clamping, the electric push rod 3 starts to extend, driving the slider 4 to move downward along the slide bar 2, so that the upper clamping block 6 contacts the surface of the aluminum profile, and clamps the aluminum profile with constant pressure. The subsequent supplementary pressure is implemented by the pressure block 7. The outer wall of the slide bar 2 is fixedly connected to a limit strip 201. The inner wall of the slider 4 is also provided with a groove through which the limit strip 201 can pass. The inner wall of the slider 4 fits against the outer surface of the slide bar 2, thereby ensuring the stability of the slider 4 when sliding.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, a support frame 131 is fixedly connected to the side wall of the base frame 401, and an inner clamping block 13 is fixedly connected to the other end of the support frame 131. The inner clamping block 13 is located below the upper clamping block 6, and there is a certain gap between the inner clamping block 13 and the upper clamping block 6, so that the inner clamping block 13 can easily extend into the inner side of the aluminum profile. When clamping, the inner clamping block 13 is first extended in, and then the electric push rod 3 is activated to drive the upper clamping block 6 to descend and clamp the aluminum profile. Furthermore, a stop block 12 is slidably connected to the inner side of the inner clamping block 13. A second connecting rod 11 is rotatably connected between the abutment block 12 and the side wall of the swing rod 9 via a hinge seat. When the swing rod 9 swings and pulls the upper connecting rod, it also pushes the lower connecting rod. The second connecting rod 11 will push the abutment block 12 toward the top of the inner clamping block 13, so that the abutment block 12 extends and contacts the inner surface of the aluminum profile, which plays a simple supporting role from below, reduces the impact of the compressive stress of the pressure block 7 on the surface of the aluminum profile, and ensures the stability and integrity of the aluminum profile during the traction process.

[0030] It should be noted that the positions where the first connecting rod 10 and the second connecting rod 11 are connected to the swing rod 9 are located on the upper and lower sides of the swing rod 9's rotation point, respectively, so that the first connecting rod 10 can be pulled and the second connecting rod 11 can be pushed. The top of the abutment block 12 is also provided with a cushioning material such as rubber. Generally, the upper pressure block 7 contacts the aluminum profile first, and then the rubber on the top of the abutment block 12 contacts the inner wall of the aluminum profile. The rubber has a certain cushioning effect and can deform after contacting the inner wall of the aluminum profile, preventing the abutment block 12 from directly contacting and scratching the aluminum profile.

[0031] It is worth noting that, such as Figure 1 As shown, a lower clamping block 14 is fixedly connected to the lower edge of the side wall of the outer frame 1. The lower clamping block 14 is located directly below the upper clamping block 6. When clamping, the lower clamping block 14 contacts the bottom of the aluminum profile and works with the upper clamping block 6 to clamp the aluminum profile. Then, the aluminum profile is clamped and pulled. When clamping and pulling the aluminum profile, in order to increase friction and avoid damaging the surface of the aluminum profile, rubber material can be set on the surface of the lower clamping block 14 and the upper clamping block 6. For example, clamping pads made of nitrile rubber or EPDM rubber can be used. These pads not only have a high coefficient of friction, which can effectively increase the clamping force and ensure that the aluminum profile is stable and does not slip during the pulling process, but their soft texture and good elasticity can also avoid scratches or indentations on the surface of the aluminum profile.

[0032] It should be noted that this device is an improvement and design for the clamping part. The outer frame 1 is connected by a traction mechanism, such as an electric slide rail or an electric telescopic device, which drives the outer frame 1 and the entire mechanism to move laterally, thereby completing the traction of the aluminum profile. The outer side of the outer frame 1 is provided with a part connected to the traction mechanism. Since the traction mechanism technology is relatively mature and is not a technical solution that needs to be protected by this utility model, its specific structure and operating principle will not be described in detail.

[0033] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0034] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
