Description

Technical Field

[0001] This utility model relates to a tooling for conveying, clamping, and correcting the deviation of aluminum tubes produced by a PTC auxiliary electric heater. Background Technology

[0002] The aluminum tubes for PTC auxiliary electric heaters need to go through multiple continuous processes on the production line, including straightening, length setting, grooving, and flattening.

[0003] The existing conveying section generally adopts a simple limiting method of "V-shaped rollers and side rollers". However, the aluminum tube wall is relatively thin. During high-speed conveying, slight bending or local warping will cause rigid collision with the rollers, resulting in dents and scratches on the tube wall and a decrease in the pass rate. Moreover, it cannot compensate for fluctuations in pipe diameter in real time, causing the aluminum tube to shift laterally during subsequent flattening and grooving processes, resulting in a high scrap rate. Meanwhile, when the aluminum tube is upturned, the top is unrestrained, which can easily interfere with subsequent molds, causing tube jamming and machine shutdown.

[0004] Therefore, a PTC-assisted electric heater is proposed as a tooling for conveying, clamping, and correcting the deviation of aluminum tubes during production. Utility Model Content

[0005] The purpose of this invention is to provide a tooling for clamping and correcting the conveying of aluminum tubes in the production of PTC auxiliary electric heaters, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a PTC auxiliary electric heater production aluminum tube conveying clamping and correction tooling, comprising: The support frame is installed on the aluminum tube conveyor line of the PTC auxiliary electric heater; A support plate is fixed to the bottom of the support frame; The clamping and correction assembly is installed on the support frame and located above the support plate, together with the support plate defining a guiding and conveying area for the aluminum tube to pass through in a straight line; The clamping and correction assembly includes a shaft horizontally positioned above the guide conveying area and several clamping guide plates. The several clamping guide plates are suspended side by side along the axial direction on the outer periphery of the shaft. Each clamping guide plate can swing independently and hang down naturally due to its own weight. Adjacent clamping guide plates fit together to form a curtain-like structure that can be passively opened. A top limiting member is provided above the clamping guide plate to apply a reverse pressing force to the plate that has been pushed upward by the aluminum tube; When the aluminum tube moves along the guide conveying area, the aluminum tube push-up part clamps the guide plate to form a channel, while the remaining clamping guide plates remain drooping to laterally limit the aluminum tube. At the same time, the top limiting component inhibits the clamping guide plate from being raised excessively, thereby achieving top deviation correction of the aluminum tube.

[0007] Preferably, a limiting bushing is provided on the outer periphery of the shaft, and the limiting bushing is driven to rotate by a motor fixed to the support frame, so that the motor drives the limiting bushing to control the lifting of the clamping guide plate.

[0008] Preferably, the top limiting member includes a pressure roller, the two ends of which are supported by connecting plates at both ends of the shaft and are parallel to the shaft.

[0009] Preferably, the clamping guide plate is an arc-shaped plate with several toothed grooves on its lower surface to increase frictional damping with the surface of the aluminum tube.

[0010] Preferably, the upper part of the clamping guide plate has a through hole, which is clearance-fitted with the shaft, so that the clamping guide plate is suspended from the shaft and can rotate independently.

[0011] Preferably, the thickness of the clamping guide plate is less than the wall thickness of the aluminum tube. When the aluminum tube passes through, the aluminum tube simultaneously lifts multiple sets of clamping guide plates at the corresponding positions. The gap between the clamping guide plates on both sides that are not lifted and the aluminum tube provides lateral restraint for the aluminum tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model adopts a clamping guide plate that can swing independently and hangs down naturally due to its own weight. During the conveying process, the aluminum tube can flexibly push the guide plate, avoiding the rigid collision caused by the traditional V-shaped roller and side roller, effectively preventing dents or scratches on the surface of the aluminum tube, and significantly improving the surface quality of the aluminum tube.

[0013] The curtain-type structure design of the clamping guide plate allows it to be dynamically adjusted according to the actual diameter and shape of the aluminum tube. It is especially suitable for situations where the tube diameter fluctuates within a certain range, eliminating the need for frequent manual adjustments to the equipment and greatly improving production efficiency and equipment versatility.

[0014] The top limiting component can apply reverse pressure to the clamping guide plate that is pushed and lifted by the aluminum tube, effectively suppressing the phenomenon of the aluminum tube tilting upwards, avoiding interference with subsequent molds, thereby reducing the risk of tube jamming and machine shutdown, and ensuring the continuity of the production line.

[0015] The thickness of the clamping guide plate is designed to be less than the wall thickness of the aluminum tube, so that when the aluminum tube passes through, only the guide plate at the corresponding position is lifted, while the other guide plates remain in a drooping state and form a small gap with the side of the aluminum tube. This achieves flexible lateral restraint of the aluminum tube, reduces the lateral displacement of the aluminum tube in subsequent processes, and lowers the scrap rate.

[0016] The toothed grooves on the lower surface of the clamping guide plate can significantly increase the friction with the surface of the aluminum tube, preventing the aluminum tube from slipping or shifting position during transportation, and further improving the stability and accuracy of transportation.

[0019] To facilitate the resolution of existing problems, this utility model provides a PTC auxiliary electric heater manufacturing aluminum tube conveying clamping and correction fixture. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Please see Figure 1-5 This utility model provides a package including: Support frame 1 is installed on the aluminum tube conveying line of the PTC auxiliary electric heater; The support plate 2 is fixed to the bottom of the support frame 1; The clamping and correction component 3 is installed on the support frame 1 and located above the support plate 2, together with the support plate 2, defining a guiding and conveying area for the aluminum tube to pass through in a straight line; The clamping and correction assembly 3 includes a shaft 31 horizontally positioned above the guiding and conveying area and several clamping guide plates 32. The clamping guide plates 32 are axially arranged side-by-side and suspended on the outer periphery of the shaft 31. Each clamping guide plate 32 can swing independently and naturally droop due to its own weight. Adjacent clamping guide plates 32 are fitted together to form a passively openable curtain-like structure. A limiting bushing 4 is provided on the outer periphery of the shaft 31, and the limiting bushing 4 is driven to rotate by a motor 5 fixed to the support frame 1, so that the motor 5 drives the limiting bushing 4 to control the lifting of the clamping guide plates 32. The clamping guide plate 32 is an arc-shaped plate with several grooves 321 on its lower surface to increase frictional damping with the aluminum tube surface. A through hole 322 is provided in the upper part of the clamping guide plate 32, and the through hole 322 is clearance-fitted with the shaft 31, allowing the clamping guide plate 32 to be suspended from the shaft 31 and to swing independently. The thickness of the clamping guide plate 32 is less than the wall thickness of the aluminum tube. When the aluminum tube passes through, the aluminum tube will simultaneously lift the multiple sets of clamping guide plates 32 at the corresponding positions. The gap between the clamping guide plates 32 on both sides that are not lifted and the aluminum tube will limit the aluminum tube from the side.

[0021] A top limiting member 33 is provided above the clamping guide plate 32 to apply a reverse pressing force to the plate that has been pushed upward by the aluminum tube; the top limiting member 33 includes a pressure roller 331, the two ends of which are supported by the connecting plate 332 at both ends of the shaft 31 and are parallel to the shaft 31.

[0022] When the aluminum tube moves along the guide conveying area, the aluminum tube push-up part clamps the guide plate 32 to form a channel, while the remaining clamping guide plates 32 remain hanging down to laterally limit the aluminum tube. At the same time, the top limiting member 33 inhibits the clamping guide plate 32 from being raised excessively, thereby achieving top correction of the aluminum tube.

[0023] The working principle of the PTC auxiliary electric heater production aluminum tube conveying clamping and correction tool provided by this utility model is as follows: fix the tooling at a suitable position on the aluminum tube conveying line, connect the motor power supply, and ensure that all components are in the initial state to prepare for aluminum tube conveying.

[0024] Turn on the motor to drive the limit bushing to rotate, so that the clamping guide plate swings to a suitable initial angle, and the clamping guide plate rotates onto the aluminum tube and is pushed by the aluminum tube.

[0025] The aluminum tube moves along the guide conveying area under the action of the conveying power. It is lifted upward by the push guide plate to form a channel. The two sides are not pushed by the push guide plate and remain vertically hanging down, which limits the aluminum tube laterally and prevents it from deviating laterally.

[0026] The top limiting component applies a reverse pressing force to the clamping guide plate that is pushed up, and inhibits the aluminum tube from tilting upward through mechanical transmission, ensuring that the top of the aluminum tube is flat, avoiding interference with subsequent molds, and reducing the risk of tube jamming and machine shutdown.

[0027] Because the thickness of the clamping guide plate is less than that of the aluminum tube wall, the aluminum tube only pushes against the corresponding guide plate when it passes through. The guide plates on both sides that are not pushed form a small gap with the side of the aluminum tube, achieving flexible lateral limiting. It can also automatically adapt to small fluctuations in the diameter of the aluminum tube, eliminating the need for frequent manual adjustments and improving production efficiency.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
