Description

Technical Field

[0001] This utility model relates to a tooling for preventing deviation in the conveying of aluminum tubes for PTC auxiliary electric heaters. Background Technology

[0002] The PTC auxiliary electric heater aluminum tube is a rectangular flat tube with a groove punched along its entire length on the upper wall. During assembly, the elastic rebound of this groove is used to press and fix the PTC ceramic element and electrode sheet, thus forming a self-clamping electric heating assembly. Due to the large long side dimension and thin wall (0.4 mm to 0.8 mm) of the rectangular cross-section, it is more prone to lateral tipping during transportation.

[0003] Existing technologies typically employ fixed side baffles for anti-deviation measures, with rigid baffles installed on both sides of the conveyor line, forcing the aluminum tubes to straighten after impact. This method exerts a large impact force on the sidewalls of the aluminum tubes, easily causing dents and scratches; moreover, the fixed spacing of the baffles requires complete disassembly and assembly during model changes, resulting in a long debugging time.

[0004] Alternatively, a single-sided elastic scraper can be used, employing a sponge or rubber scraper to elastically hold the aluminum tube in place. While this reduces the impact force, the scraper wears out quickly, is prone to aging under high temperatures, and can only limit movement on one side, offering limited effectiveness in suppressing bidirectional swaying.

[0005] Therefore, a tooling for preventing deviation in the conveying of aluminum tubes for PTC auxiliary electric heaters is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a tooling for preventing deviation in the conveying of aluminum tubes for PTC auxiliary electric heaters, so as to solve the problems mentioned in the background art.

The lower edge of the anti-deviation plate is lower than the upper surface of the aluminum tube during the conveying process, and each anti-deviation plate hangs down naturally under its own weight to form a lateral limiting surface to prevent the aluminum tube from tilting laterally during the conveying process.

[0008] Preferably, the lower part of the anti-deviation plate extends in a fan shape, the back side of the anti-deviation plate is provided with an arc-shaped surface, and anti-slip teeth are provided on the lower surface of the anti-deviation plate to increase the frictional resistance with the surface of the aluminum tube.

[0009] Preferably, the front end of the anti-deviation rod is provided with a limiting protrusion, and the front end of the through groove is provided with a corresponding positioning groove.

[0010] Preferably, the anti-deviation rod has a threaded hole at its tail end, and the bearing plate has a countersunk hole. An internal hex screw passes through the countersunk hole and connects with the threaded hole, thereby axially fixing the anti-deviation rod to the bearing plate.

[0011] Preferably, a limiting baffle is fixed to the back of the bearing plate by a bolt, and the lower edge of the limiting baffle is arc-shaped and abuts against the back side of the anti-deviation plate to limit the maximum backward tilt angle of the anti-deviation plate.

[0012] Preferably, a concave groove is provided below the through groove, and the width of the concave groove is greater than the thickness of the anti-deviation plate, so as to provide swing space for the anti-deviation plate.

[0013] Preferably, the thickness of the anti-deviation plate is greater than the thickness of the aluminum tube, so as to ensure that the aluminum tube can be slightly deviated below the anti-deviation plate and be corrected in time.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention, through its curtain-like structure, anti-deviation plate, and arc-shaped surface, effectively prevents the aluminum tube from tilting laterally during transport, thus improving the stability of the transport process.

[0015] Compared with traditional fixed side guards, the new tooling adopts a flexible contact method, which avoids rigid impact on the side wall of the aluminum tube and reduces the risk of dents and scratches on the surface of the aluminum tube.

[0016] It can also adapt to aluminum tubes of different outer diameters and lengths, and has good versatility, reducing the adjustment work caused by changes in aluminum tube specifications.

[0017] The tooling has a simple structure, is resistant to high temperatures, meets the needs of long-term use, reduces maintenance costs, and improves overall durability.

[0018] With its simple structure, few parts, and no need for additional power, sensors, or control systems, it reduces the cost per unit and offers good economic benefits. Attached Figure Description

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, and 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.

[0022] Please see Figure 1-5 This utility model provides a tooling for preventing deviation in the conveying of aluminum tubes for PTC auxiliary electric heaters, comprising: The support plate 1 extends along the conveying direction of the aluminum tube, and a through groove 11 is provided at the lower part of the support plate 1; a limit baffle 6 is fixed to the back of the support plate 1 by a bolt 5, and the lower edge of the limit baffle 6 is arc-shaped and abuts against the back side of the anti-deviation plate 3 to limit the maximum backward tilt angle of the anti-deviation plate 3.

[0023] A concave groove 14 is provided below the through groove 11. The width of the concave groove 14 is greater than the thickness of the anti-deviation plate 3, providing swing space for the anti-deviation plate 3.

[0024] An anti-deviation rod 2 is detachably inserted laterally through the through groove 11, and the axis of the anti-deviation rod 2 is perpendicular to the aluminum tube conveying direction. A limiting protrusion 21 is provided at the front end of the anti-deviation rod 2, and a corresponding positioning groove 12 is provided at the front end of the through groove 11. The limiting protrusion 21 and the positioning groove 12 are shape-coupled to prevent the anti-deviation rod 2 from rotating relative to the support plate 1. A threaded hole 22 is provided at the rear end of the anti-deviation rod 2, and a countersunk hole 13 is provided on the support plate 1. An internal hexagon screw 4 passes through the countersunk hole 13 and connects to the threaded hole 22, thereby axially fixing the anti-deviation rod 2 to the support plate 1.

[0025] Several anti-deviation plates 3 are sequentially sleeved on the anti-deviation rod 2 to form a continuous curtain-like structure, and each anti-deviation plate 3 can rotate independently around the anti-deviation rod 2; The lower edge of the anti-deviation plate 3 is lower than the upper surface of the aluminum tube during the conveying process, and each anti-deviation plate 3 hangs down naturally under its own weight to form a lateral limiting surface to prevent the aluminum tube from tilting laterally during the conveying process.

[0026] The lower part of the anti-deviation plate 3 extends in a fan shape. The back side of the anti-deviation plate 3 is provided with an arc-shaped surface 31, and anti-slip teeth 32 are provided on the lower surface of the anti-deviation plate 3 to increase the frictional resistance with the surface of the aluminum tube.

[0027] The thickness of the anti-deviation plate 3 is greater than the thickness of the aluminum tube, so as to ensure that the aluminum tube can be slightly deviated below the anti-deviation plate 3 and be corrected in time.

[0028] The working principle of the PTC auxiliary electric heater aluminum tube conveying anti-deviation tooling provided by this utility model is as follows: Start the conveying equipment, and the aluminum tube enters the anti-deviation fixture along the conveying direction. The lower edge of the initial end of the anti-deviation plate 3 is lower than the upper surface of the aluminum tube, so that when the aluminum tube is conveyed, the arranged curtain-shaped anti-deviation plates 3 are pushed open in the moving direction. At this time, the anti-deviation plates 3 naturally droop under their own weight. At the same time, the gap created by the pushed-open anti-deviation plates 3 is used for the conveying and moving of the aluminum tube. The anti-deviation plates 3 located on both sides of the aluminum tube perform anti-deviation treatment on the aluminum tube, form a lateral limit on the aluminum tube, and prevent the aluminum tube from tilting laterally during the conveying process.

[0029] Meanwhile, the anti-slip teeth 32 on the lower surface of the anti-deviation plate 3 increase the frictional resistance with the surface of the aluminum tube, further stabilizing the conveying of the aluminum tube.

[0030] Once the aluminum tube returns to its normal conveying path, the anti-deviation plate 3 automatically resets under its own weight and naturally droops to the upper surface of the aluminum tube to re-form a limiting surface, ready to guide and straighten any aluminum tubes that may subsequently deviate.

[0031] 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.
