Description

Technical Field

[0001] This utility model relates to the field of steel pipe cutting technology, specifically to a stainless steel pipe fitting production cutting equipment. Background Technology

[0002] The appropriate method for cutting stainless steel pipes should be selected based on the pipe diameter, thickness, precision, and budget. For small diameter pipes, manual pipe cutters can be used, which are flexible and suitable for simple processing. Band saws and other mechanical cutting methods are suitable for medium and thick pipes, with fast cutting speeds but require fixing the pipe and may result in burrs on the cut. Abrasive wheel cutting is low-cost but easily leaves burrs, requiring subsequent grinding. Laser cutting has high precision and smooth cuts, making it suitable for complex shapes or mass production, but the equipment cost is high. Plasma cutting is fast and can cut thick pipes, but the cut surface may oxidize and discolor.

[0003] During mass production, considering production costs and equipment upgrade costs, we continue to use abrasive wheel cutting, followed by burr removal, which effectively controls costs. However, the following problems easily occur during the cutting process: the abrasive wheel feed can easily flatten or turn the stainless steel pipe end into an oval shape, affecting subsequent welding or splicing; deformation during the cutting process can cause the cut surface to be non-perpendicular to the axis of the stainless steel pipe, resulting in a tilted cut surface, which urgently needs improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stainless steel pipe cutting device to solve the problem of inclined stainless steel pipe ends and cut surfaces that are easily caused by cutting stainless steel pipes with a feed grinding wheel.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A stainless steel pipe cutting production equipment includes a main unit, a lifting head mounted on the main unit, a cutting grinding wheel below the lifting head, a widening equipment platform at the bottom of the main unit, a support roller for supporting the stainless steel pipe on the widening equipment platform, and a fixed stop block located on one side of the support roller and the stainless steel pipe on the widening equipment platform.

[0007] A fixed base is vertically fixed on the side of the fixed block away from the stainless steel pipe on the widening equipment platform. A support rod and a guide rod are movably inserted into the fixed base. A support cylinder that can be movably inserted into the stainless steel pipe is rotatably connected to one end of the support rod corresponding to one end of the stainless steel pipe. The other end of the support rod is fixedly connected to the guide rod through a connecting frame. A translation push rod with the front end of the piston rod fixedly connected to the connecting frame is also fixed on the fixed base.

[0008] Preferably, the supporting rotating cylinder is coaxially arranged with the stainless steel pipe, and the outer diameter of the supporting rotating cylinder is adapted to the inner diameter of the stainless steel pipe.

[0009] Preferably, the end of the supporting rotating cylinder corresponding to the stainless steel tube has a guide cone structure. The supporting rotating cylinder is rotatably connected to the supporting rod through a rotating bushing. A fixed retaining ring is fixedly sleeved on the supporting rod at one end of the supporting rotating cylinder corresponding to the fixed seat. A limiting plate supporting the end of the supporting rod opposite to the fixed seat is threadedly installed on the end of the supporting rotating cylinder opposite to the fixed seat.

[0010] Preferably, the support rod has a hollow structure, and both the support rod and the guide rod are slidably connected to the fixed seat through sliding sleeves.

[0011] Preferably, there are at least two guide rods symmetrically arranged around the translation push rod.

[0012] Preferably, the translation push rod and the guide rod are both located above the stainless steel tube, and the fixed stop is located below the support rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features a retractable, adjustable support cylinder that can be inserted into the stainless steel pipe for cutting support. During the cutting process, the synchronously rotating support cylinder provides internal support, ensuring the stability of the stainless steel pipe's position and preventing axial deviation. It also provides support to the inner wall of the stainless steel pipe, preventing deformation caused by the feed cutting wheel and ensuring the verticality of the cut end. This improves the quality of the stainless steel pipe fittings and solves the problem of tilted pipe ends and cut surfaces that easily occur when cutting stainless steel pipes with a feed grinding wheel.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-3 As shown, this utility model provides a technical solution: a stainless steel pipe cutting production equipment, including a main unit 1, a lifting head 2 installed on the main unit 1, a cutting grinding wheel 3 arranged below the lifting head 2, a widened equipment platform 4 arranged at the bottom of the main unit 1, a support roller 6 for supporting stainless steel pipe 5 arranged on the widened equipment platform 4, and a fixed stop block 7 fixed on the widened equipment platform 4 located on one side of the support roller 6 and the stainless steel pipe 5.

[0021] A fixed base 8 is vertically fixed on the side of the fixed block 7 away from the stainless steel pipe 5 on the widened equipment platform 4. A support rod 9 and a guide rod 10 are movably inserted into the fixed base 8. A support cylinder 11 that can be movably inserted into the stainless steel pipe 5 is rotatably connected to one end surface of the support rod 9. The support cylinder 11 is coaxial with the stainless steel pipe 5, and the outer diameter of the support cylinder 11 is adapted to the inner diameter of the stainless steel pipe 5.

[0022] The supporting rotating cylinder 11 has a guide cone structure at one end corresponding to the stainless steel tube 5. The supporting rotating cylinder 11 is rotatably connected to the supporting rod 9 through the rotating bushing 17. A fixed retaining ring 14 is fixedly sleeved on the supporting rod 9 at one end of the supporting rotating cylinder 11 corresponding to the fixed seat 8. A limiting plate 15 is threadedly installed at the end of the supporting rod 9 away from the fixed seat 8, which is supported at the end of the supporting rotating cylinder 11 away from the fixed seat 8.

[0023] The support rod 9 has a hollow structure. Both the support rod 9 and the guide rod 10 are slidably connected to the fixed seat 8 through the sliding sleeve 16. The other end of the support rod 9 is fixedly connected to the guide rod 10 through the connecting frame 12. The fixed seat 8 is also fixed with a translation push rod 13 whose front end of the piston rod is fixedly connected to the connecting frame 12. There are at least two guide rods 10 and they are symmetrically arranged around the translation push rod 13. The translation push rod 13 and the guide rod 10 are both located above the stainless steel tube 5. The fixed stop block 7 is located below the support rod 9.

[0024] Working principle:

[0025] Before cutting, the translation push rod 13 drives the support rotating cylinder 11 to move horizontally to the left through the connecting frame 12 and the support rod 9, inserting it into the stainless steel pipe 5. The support rotating cylinder 11 is rotatably connected to the support rod 9. When the cutting abrasive wheel 3 moves downward to feed and rotates to cut the stainless steel pipe 5, the support rotating cylinder 11 can rotate with the stainless steel pipe 5, while supporting the inner wall of the stainless steel pipe 5 to ensure that the stainless steel pipe 5 is stable in position and does not deviate from its axis, avoiding deformation by the feed cutting abrasive wheel 3, and ensuring that the cut end face is vertical. After cutting, the translation push rod 13 drives the support rotating cylinder 11 to move horizontally to the right through the connecting frame 12 and the support rod 9. During the movement, the cut stainless steel pipe is separated from the support rotating cylinder 11 by the blocking of the fixed stop 7. This process is repeated to ensure that the stainless steel pipe end is full and the cut surface is vertical, thus improving the quality.
