Description

Technical Field

[0001] This utility model belongs to the field of stainless steel pipe punching technology, specifically relating to a punching device for external thread cutting of stainless steel pipes. Background Technology

[0002] When connecting existing stainless steel pipes, a tapered sleeve with external threads is usually installed on the stainless steel pipe. Then, a slit is made in the tapered sleeve. After the round bar is placed inside the tapered sleeve, the tapered sleeve contracts inward after the nut is tightened, thus holding the round bar tightly so that it does not slip with the round bar and is easy to disassemble.

[0003] The existing tapered sleeves are usually made using milling cutters, cutting tools, and wire cutting processes. All of these processes use the principle of friction cutting, which can easily produce burrs and cause heat during processing, affecting the external threads. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a punching device for the external thread of stainless steel pipes, which can directly punch without burrs or damage to the threads.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stainless steel pipe external thread cutting device, including a worktable, a support base, a support inner column, and a cutting head. The support base is installed on the worktable, the support inner column is set on the support base, and a gap is provided between the outer wall of the support inner column and the support base for the stainless steel pipe wall to extend into. The diameter of the support inner column is adapted to the inner diameter of the stainless steel pipe. A punch is provided on one side of the worktable on the support base, and the cutting head is installed on the punching end of the punch. The side of the support inner column facing the cutting head is recessed with a groove.

[0006] The thickness of the punching head is less than the width of the groove.

[0007] The worktable has a positioning component on the side away from the support.

[0008] The positioning component includes a positioning seat and a positioning tube. The positioning seat is fixedly installed on the workbench, and the positioning tube is fixedly installed on the positioning seat. A nut is threaded onto the stainless steel tube, and the nut is adapted to the inner diameter of the positioning tube.

[0009] The inner wall of the positioning tube is provided with four fixing grooves at equal intervals, and the nut is screwed with a positioning post that matches the fixing groove.

[0010] The bottom of the positioning seat is provided with two connecting posts, and the worktable is provided with connecting holes that cooperate with the two connecting posts. The connecting posts are iron posts, and magnets are provided in the connecting holes.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a stainless steel pipe external thread cutting and punching device. When cutting, the stainless steel pipe is sleeved on the inner support column and placed on the support seat. Then, the punching head is driven by the punch to punch. The punch, in conjunction with the groove, punches away the groove to be cut in the stainless steel pipe. There are no burrs and the threads are not damaged. It is faster than the friction cutting process of the original milling cutter, cutting tool and wire cutting, and the produced products are more stable, more environmentally friendly and lower in cost.

[0014] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0015] like Figures 1-5As shown, this embodiment provides a stainless steel pipe external thread cutting device, including a worktable 1, a support base 2, a support inner column 3, and a cutting head 4. The support base 2 is mounted on the worktable 1, and the support inner column 3 is disposed on the support base 2. A gap is provided between the outer wall of the support inner column 3 and the support base 2 for the stainless steel pipe 10 wall to extend into. The diameter of the support inner column 3 is adapted to the inner diameter of the stainless steel pipe 10. A punch 5 is provided on one side of the support base 2 on the worktable 1, and the cutting head 4 is mounted on the punching end of the punch 5. A groove 6 is recessed on the side of the support inner column 3 facing the cutting head 4. Specifically, the thickness of the cutting head 4 is less than the width of the groove 6. When performing the cutting process, the stainless steel tube 10 is sleeved on the inner support column 3 and placed on the support seat 2. Then, the punch 5 drives the punching head 4 to punch. The punch, in conjunction with the groove 6, punches away the groove that needs to be cut in the stainless steel tube 10. There are no burrs and the threads are not damaged. This process is faster than the friction cutting process using milling cutters, cutting tools and wire cutting. The produced products are more stable, more environmentally friendly and lower in cost.

[0016] Furthermore, the workbench 1 has a positioning component 7 on the side away from the support base 2. Specifically, the positioning component 7 includes a positioning seat 8 and a positioning tube 9. The positioning seat 8 is fixedly installed on the workbench 1, and the positioning tube 9 is fixedly installed on the positioning seat 8. A nut 11 is threaded onto the stainless steel tube 10, and the nut 11 is adapted to the inner diameter of the positioning tube 9. By placing the nut 11 on the positioning tube 9, the stainless steel tube 10 is further fixed, ensuring greater stability of the stainless steel tube 10 during punching.

[0017] Furthermore, the inner wall of the positioning tube 9 is provided with four equally spaced fixing grooves 12, and a positioning post 13 adapted to the fixing groove 12 is screwed onto the nut 11. When a second, third, or fourth cut is needed after one cut is completed, the stainless steel tube 10 can be pulled out to allow the nut 11 to exit the positioning tube 9, thereby rotating the stainless steel tube 10 to drive the nut 11 to rotate, so that the positioning post 13 is positioned facing different fixing grooves 12. Pushing the stainless steel tube 10 drives the nut 11 to be placed inside the positioning tube 9, and the positioning post 13 is placed in the corresponding fixing groove 12 to form a fixation, ensuring that when cutting four cuts, the cuts can be equally spaced on the stainless steel tube 10.

[0018] Furthermore, the bottom of the positioning seat 8 is provided with two connecting posts 16, and the worktable 1 is provided with connecting holes 14 that mate with the two connecting posts 16. The connecting posts 16 are iron posts, and magnets 15 are provided in the connecting holes 14. Through the magnetic attraction between the iron posts and the magnets 15, the positioning seat 8 is stably placed on the worktable 1. The positioning seat 8 can also be removed and replaced to accommodate nuts 11 with different outer diameters.

[0019] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
