Description

Technical Field

[0001] This invention relates to the field of aluminum alloy profile extrusion forming equipment technology, and in particular to a tension adaptive adjustable aluminum alloy profile traction machine. Background Technology

[0002] Aluminum alloy profiles, with their advantages of being lightweight, high-strength, corrosion-resistant, and easy to process, are widely used in construction, rail transportation, new energy equipment, aerospace, and other fields. In the hot extrusion production process of aluminum profiles, the traction machine, as a core supporting equipment, plays a crucial role in applying stable traction force to the high-temperature profiles in the extrusion die, ensuring uniform profile output, maintaining cross-sectional dimensional accuracy and straightness, and preventing bending, twisting, and surface scratches. The stability of its traction tension directly determines the profile yield, surface quality, and production efficiency.

[0003] Existing aluminum profile traction machines mostly adopt open-loop speed control or fixed tension preset mode, and are mainly composed of traction frame, clamping mechanism, transmission mechanism and conventional frequency conversion / servo drive unit. The following common technical defects exist in actual production.

[0004] The speed of the extrusion master cylinder fluctuates microscopically, the cross-section of the profile changes, the temperature is uneven, and the frictional resistance changes dynamically. Traditional traction machines cannot sense and respond quickly to tension deviations in real time. This can easily lead to excessive tension causing the profile to stretch and become thinner, resulting in dimensional deviations, or insufficient tension causing the profile to accumulate and bend. This is especially true for thin-walled, high-precision, and complex cross-section profiles. Tension adjustment relies on manually preset parameters or delayed feedback correction, resulting in a large response delay. This makes it difficult to match the dynamic working conditions of high-speed extrusion production lines, leading to uneven stress on the profiles before cooling and shaping, causing quality problems such as residual internal stress, poor straightness, and twisting.

[0005] Traditional traction machines lack adaptive buffering and tension closed-loop adjustment mechanisms, resulting in large transmission impacts, easy clamping slippage and surface damage, high equipment failure rate, increased maintenance costs, and difficulty in meeting the continuous and stable production needs of high-end aluminum profiles. Summary of the Invention

The inner wall of the hollow transmission wheel is connected to the profile support rod through a traction spring.

Detailed Implementation

[0030] The technical solution provided by the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-12 As shown, a tension adaptive adjustable aluminum alloy profile traction machine includes a traction bracket 1. The traction bracket 1 includes a bracket base 101, and a sliding bracket 102 is fixedly installed on the bracket base 101. A pair of traction clamps 2 are laterally slidably installed on the top of the sliding bracket 102. The traction clamps 2 include clamp bases 201, which are laterally slidably installed inside the sliding bracket 102. A clamp support frame 202 is laterally slidably installed on the bottom of the clamp base 201. A clamp sliding base 204 is longitudinally slidably installed on the clamp support frame 202. A clamp support plate 205 is laterally slidably installed at the front end of the clamp sliding base 204. A bottom clamp is fixedly installed at the bottom of the clamp support plate 205. The bracket 206 has a bottom clamping plate 207 that is longitudinally slidably mounted on it. A compression spring is fixedly installed between the bottom clamping plate 207 and the bottom clamping bracket 206. An arc-shaped plate is laterally rotatably mounted on the top of the bottom clamping plate 207. A torsion spring is fixedly installed between the arc-shaped plate and the bottom clamping plate 207. The bottom clamping plate 207 is used to fit tightly against the bottom of the profile. By sliding the bottom clamping plate 207 on the bottom clamping bracket 206, it can adapt to profiles of different shapes. The arc-shaped plate at the top of the bottom clamping plate 207 can increase the contact area with the profile and avoid the pressure concentration during dragging and pulling, which would cause the bottom clamping plate 207 to leave a dent on the profile and result in scrap.

[0032] like Figures 1-12 As shown, a top clamping bracket 211 is fixedly installed on the top of the clamping support plate 205. A clamping support rod 224 is rotatably installed on the top clamping bracket 211. Multiple top clamping plates 208 are rotatably installed on the clamping support rod 224. A telescopic friction plate 217 is radially slidably installed on the bottom of the top clamping plate 208. A compression spring is fixedly installed between the telescopic friction plate 217 and the top clamping plate 208. The top clamping plate 208 is used to fit against the top of the profile. By fitting the telescopic friction plate 217 against the top of the profile, the friction between the top clamping plate 208 and the profile can be increased, while protecting the surface of the profile and preventing dents.

[0033] like Figures 1-12As shown, a clamping transmission rod 210 is laterally rotatably mounted on the top clamping bracket 211. A drive motor is fixedly mounted on the top clamping bracket 211 and is fixedly connected to the clamping transmission rod 210. Multiple transmission gears 209 are laterally rotatably mounted on the clamping transmission rod 210. A torsion spring is fixedly mounted between the transmission gears 209 and the clamping transmission rod 210. Multiple transmission racks 215 are laterally slidably mounted inside the top of the top clamping bracket 211. The transmission racks 215 mesh with the transmission gears 209. Gears are fixedly mounted on the top clamping plate 208. The gears on the top clamping plate 208 mesh with the transmission racks 215. By starting the drive motor, the clamping transmission rod 210 is driven to rotate. During rotation, the transmission gear 209 is driven to rotate by adjusting the spring coil 216. The rotation of the transmission gear 209 causes the transmission rack 215 to slide laterally within the top clamping bracket 211. When the transmission rack 215 slides, it causes the top clamping plate 208 to rotate on the clamping support rod 224 and come into contact with the surface of the top of the profile. When the top clamping plate 208 comes into contact with the surface of the profile, it can no longer rotate due to resistance. At this time, the transmission gear 209 connected by the adjusting spring coil 216 can rotate in the opposite direction on the clamping transmission rod 210, so that other top clamping plates 208 that are not in contact with the profile can continue to rotate. This ensures that each top clamping plate 208 has a certain pressure with the profile, giving it sufficient friction to drag and pull the profile and prevent slippage.

[0034] like Figures 1-12As shown, a buffer cylinder support plate 219 is laterally slidably installed inside the clamp sliding base 204. A third adjusting motor 220 is fixedly installed on the clamp sliding base 204, and a screw is fixedly installed on the third adjusting motor 220. The screw on the third adjusting motor 220 cooperates with the lead screw of the buffer cylinder support plate 219. A pair of buffer inner cylinders 218 are fixedly installed on the buffer cylinder support plate 219, and a buffer outer cylinder 223 is fixedly installed on the clamp support plate 205. The buffer outer cylinder 223 is slidably engaged with the buffer inner cylinders 218. High-pressure gas is stored between the buffer outer cylinder 223 and the buffer inner cylinders 218. Utilizing the compressibility of air, when the profile encounters a sudden change in traction force during the traction process, the buffer outer cylinder 223 can slide on the buffer inner cylinders 218 to buffer and self-adjust the suddenly increased or decreased traction force, preventing the profile from being damaged due to a sudden increase in traction force. If the clamp breaks or becomes loose and bent due to a sudden decrease in traction force, the clamp sliding base 204 is connected to an external air pump through a pipe to deliver gas into the buffer inner cylinder 218. This is used to adjust the air pressure between the buffer outer cylinder 223 and the buffer inner cylinder 218 according to different profile structures, or to adjust the air pressure according to changes in traction force to change the tension during traction. Temperature transmission plates 222 are fixedly installed on the upper and lower sides of the buffer outer cylinder 223, and a temperature control component 221 is fixedly installed inside the clamp sliding base 204. The temperature control component 221 is used to cooperate with the temperature transmission plates 222 to control the temperature of the air in the buffer inner cylinder 218, keeping it at a constant temperature to maintain gas pressure. At the same time, the air pressure in the buffer inner cylinder 218 can be controlled by changing the air temperature as needed, which facilitates the adjustment of air pressure according to the traction force required for profiles of different thicknesses and materials.

[0035] like Figures 1-12 As shown, sliding monitoring devices are fixedly installed on the upper and lower sides of the inner buffer cylinder 218 to monitor the sliding distance of the outer buffer cylinder 223 on the inner buffer cylinder 218, thereby detecting the change in traction force between the equipment and the profile, so as to adjust the traction speed of the traction clamp 2 in a timely manner.

[0036] like Figures 1-12 As shown, a traction motor 103 is fixedly installed on the top of the sliding bracket 102, and a traction screw 104 is fixedly installed on the traction motor 103. The traction screw 104 cooperates with the lead screw of the clamp base 201. By starting the traction motor 103, the traction screw 104 is driven to rotate laterally. The traction screw 104 can drive the corresponding traction clamp 2 to slide laterally on the sliding bracket 102 to pull the profile.

[0037] like Figures 1-12As shown, a second adjusting motor 213 is fixedly mounted on the fixture sliding base 204, and an adjusting screw 214 is fixedly mounted on the second adjusting motor 213. The adjusting screw 214 engages with the lead screw of the fixture sliding base 204. A first adjusting motor 212 is fixedly mounted on the fixture support frame 202, and a screw is fixedly mounted on the first adjusting motor 212. The screw on the first adjusting motor 212 engages with the lead screw of the fixture base 201. By starting the second adjusting motor 213, the adjusting screw 214 is driven to rotate. When the adjusting screw 214 rotates, it drives the fixture sliding base 204 to rotate. 4. The clamp supports 202 slides longitudinally on the clamp support frame 202. At the same time, the first adjusting motor 212 is started to drive the screw to rotate. When the screw rotates, it drives the clamp support frame 202 to slide laterally on the bottom of the clamp base 201. The lateral sliding positions of the bottom clamping bracket 206 and the top clamping bracket 211 are adjusted to disengage them from the profile. Then, the traction motor 103 is started to rotate in the opposite direction to drive the traction clamp 2 to slide backward on the sliding bracket 102, so that the traction clamp 2 can return to its original position smoothly. Through the alternating cycle of the two traction clamps 2, the profile can be continuously tractioned.

[0038] like Figures 1-12As shown, multiple profile support rods 105 are laterally slidably mounted on the support base 101. Support rollers are laterally rotatably mounted on each profile support rod 105. An arc-shaped compression spring 111 is fixedly mounted between the profile support rod 105 and the support base 101. Hollow transmission wheels 106 are laterally rotatably mounted at both ends of the profile support rod 105. The inner wall of the hollow transmission wheel 106 is connected to the profile support rod 105 via a traction spring 107. Hollow rollers 110 are laterally rotatably mounted on the outer ring of the hollow transmission wheel 106. A transmission rod 10 is fixedly mounted on the inner wall of the hollow roller 110. 9. Multiple pairs of limiting roller rods 108 are fixedly installed on the outer ring of the hollow transmission wheel 106. A torsion spring is fixedly installed between the limiting roller rod 108 and the hollow transmission wheel 106 to limit and control the mutual cooperation of each pair of limiting roller rods 108 to clamp in a V-shape. The limiting roller rod 108 is in sliding cooperation with the transmission round rod 109. The transmission round rod 109 is located at the tip of each pair of limiting roller rods 108 to limit the unidirectional rotation of the hollow roller 110 on the hollow transmission wheel 106. A clamp transmission plate 203 is fixedly installed at the bottom of the clamp support frame 202. The clamp transmission plate 203 and the clamp transmission plate 203 are fixedly installed with the hollow transmission wheel 106 to limit the unidirectional rotation of the hollow roller 110 on the hollow transmission wheel 106. Hollow rollers 110 roll in a rolling engagement. When the traction clamp 2 pulls the profile, the lateral sliding of the clamp transmission plate 203 drives the hollow rollers 110 to rotate on the hollow transmission wheel 106. During the rotation of the hollow rollers 110, the transmission rod 109 contacts the tip of the limiting roller rod 108. The unidirectional rotation of the limiting roller rod 108 drives the hollow transmission wheel 106 to rotate synchronously. When the hollow transmission wheel 106 rotates, the traction spring 107 pulls the profile support rod 105 to rotate together, causing the profile support rod 105 in the traction direction of the traction clamp 2 to rotate downwards. The rotation avoids the support rollers on the profile support rod 105 from obstructing the bottom clamping bracket 206. After the clamp transmission plate 203 passes, the profile support rod 105 is driven to rotate in the opposite direction back to the original angle by the arc compression spring 111 to support the profile. When the traction clamp 2 returns, it drives the hollow roller 110 to rotate in the opposite direction through the clamp transmission plate 203. The transmission rod 109 slides from the rear end to the front end through the two pairs of limit roller rods 108, so that the hollow roller 110 rotates in the opposite direction on the hollow transmission wheel 106 without affecting the rotation angle of the profile support rod 105.
