Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gas cylinder pipe processing equipment, specifically relating to a widened, closely toothed clamp. Background Technology
[0002] Gas cylinders are required for high-pressure hydrogen storage. Currently, the inner liner of gas cylinders is mainly made of thin-walled aluminum alloy tubes. These tubes are primarily manufactured using a cold-drawing process. During the cold-drawing process, clamps are needed to clamp the ends of the thin-walled tubes. Because the aluminum alloy tubes have thin walls, the clamping area is relatively small when using traditional steel pipe clamps to hold them, which can easily cause the clamps to break during cold drawing, resulting in significant waste of raw materials. Utility Model Content
[0003] The purpose of this utility model is to provide a widened, closely spaced toothed clamp. This clamp is an improvement on the original structure of the steel pipe clamp, which enables reliable clamping of the clamp part during the cold drawing process of aluminum alloy thin-walled tubes, effectively preventing the breakage of the clamp part and reducing the loss of raw materials.
[0004] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: a widened, closely spaced toothed clamp includes an original clamp with multiple first-step holes machined on it. A wide clamp is fixedly installed on the inner side of the original clamp, and a second-step hole is machined on the wide clamp. The positions of the first-step holes and the second-step holes correspond to each other. The wide clamp and the original clamp are fixedly connected by bolts. The bolts pass through the second-step holes and the first-step holes in sequence and are fixedly connected to the clamp mounting base. The clamp mounting base is machined with threaded holes for fixed connection with the bolts. The inner wall of the wide clamp is machined with closely spaced teeth.
[0005] The original clamp has original clamp teeth on its inner sidewall, and the original clamp teeth contact and engage with the outer wall of the wide clamp.
[0006] The large end face of the original clamp is machined with bolt holes.
[0007] The clamp teeth are used to engage with the outer wall of the aluminum alloy tube to be clamped.
[0008] The depth of the clamp teeth is less than the depth of the original clamp teeth.
[0009] The central angle corresponding to the wide clamp is greater than the central angle corresponding to the original clamp.
[0010] The wide clamp consists of three parts, which are divided into four segments by a single round steel pipe, with one segment discarded.
[0011] The present invention has the following beneficial effects:
[0012] 1. This clamp is an improvement on the original structure of the steel pipe clamp, which enables reliable clamping of the clamp part during the cold drawing process of aluminum alloy thin-walled tubes, effectively preventing the breakage of the clamp part and reducing the loss of raw materials.
[0013] 2. The original clamp teeth mentioned above can reliably fix the wide clamp, increase the friction, and prevent relative displacement during the subsequent pulling process.
[0014] 3. The bolt holes mentioned above facilitate the fixed installation of the original clamps.
[0015] 4. The tooth depth of the clamp is about half that of a conventional clamp, which increases the tooth density to ensure reliable clamping and fixing of the aluminum alloy tube.
[0016] 5. The aforementioned width dimensions increase the contact area between the wide clamp and the aluminum alloy tube, thereby increasing the friction to ensure reliable clamping of the aluminum alloy tube and prevent it from falling off. Attached Figure Description

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0024] like Figure 1-4As shown, a widened, closely spaced toothed clamp includes an original clamp 1 with multiple first-step holes 2 machined on it. A wide clamp 7 is fixedly mounted on the inner side of the original clamp 1, and a second-step hole 8 is machined on the wide clamp 7. The positions of the first-step holes 2 and the second-step holes 8 correspond to each other. The wide clamp 7 and the original clamp 1 are fixedly connected by bolts 4. The bolts 4 pass through the second-step holes 8 and the first-step holes 2 in sequence and are fixedly connected to the clamp mounting base 3. The clamp mounting base 3 has threaded holes 5 for fixed connection with the bolts 4. The inner wall of the wide clamp 7 is machined with closely spaced teeth 9. This clamp is an improvement on the original structure of the steel pipe clamp, which enables reliable clamping of the chuck part during the cold drawing process of aluminum alloy thin-walled tubes, effectively preventing breakage of the chuck part and reducing the loss of raw materials. In practical use, the wide clamp 7 cooperates with the outer wall of the aluminum alloy tube 11 to reliably clamp the end of the aluminum alloy tube 11, thereby ensuring reliable cold drawing in the future.
[0025] Furthermore, the inner wall of the original clamp 1 is provided with original clamp teeth 6, which contact and engage with the outer wall of the wide clamp 7. The original clamp teeth 6 reliably fix the wide clamp 7, increase the friction, and prevent relative displacement during subsequent pulling.
[0026] Furthermore, the large end face of the original clamp 1 is machined with bolt holes 10. The bolt holes 10 facilitate the fixed installation of the original clamp 1.
[0027] Furthermore, the clamp teeth 9 are used to engage with the outer wall of the aluminum alloy tube 11 to be clamped. The engagement between the clamp teeth 9 and the aluminum alloy tube 11 increases the friction between the tube and the clamp, ensuring the reliability of clamping during the drawing process.
[0028] Furthermore, the depth of the clamp teeth 9 is less than the depth of the original clamp teeth 6. The depth of the clamp teeth 9 is about half that of the conventional clamp teeth, thereby increasing the tooth density to ensure reliable clamping and fixing of the aluminum alloy tube 11.
[0029] Furthermore, the central angle corresponding to the wide clamp 7 is greater than that corresponding to the original clamp 1. This increased width increases the contact area between the wide clamp 7 and the aluminum alloy tube, thereby increasing friction and ensuring reliable clamping of the aluminum alloy tube to prevent it from slipping off.
[0030] Furthermore, the wide clamp 7 consists of three parts, each divided into four segments by a single round steel pipe 12, with one segment discarded. This processing method simplifies the manufacturing process and reduces costs.
[0031] The working process and principle of this utility model:
[0032] In practical use, the widened, closely spaced toothed clamp described above is used to securely clamp and fix the aluminum alloy tube clamp by fixing the wide clamp 7 inside the original clamp 1.
