[0002] Stainless steel pipe fittings are a general term for various stainless steel pipe connection parts. They can be divided into different categories according to shape, use, connection method, etc. They are characterized by easy installation, high performance, and durability. They are widely used in various pipeline construction and installation, including stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel pipe caps, etc. They need to be cut during processing and use.

[0003] When existing cutting equipment cuts stainless steel pipes, the cut pipes fall to various places on the processing table or even roll to the ground, making it time-consuming and laborious for workers to collect the cut pipes later. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stainless steel pipe cutting device to solve the problems in the background art.

[0005] This utility model provides the following technical solution: a stainless steel pipe cutting device, including a worktable, a triangular chuck, and a fixing rod.

A power assembly for horizontally moving the fixing rod is provided on the top of the worktable. The limiting assembly and the cutting assembly are symmetrically arranged and located between the drive assembly and the power assembly. A feeding assembly is provided between the cutting assembly and the power assembly. The feeding assembly is fixedly connected to the top of the worktable. The fixing rod passes through the feeding assembly and slides with it. The fixing rod is connected to the power assembly.

[0006] Furthermore, the drive assembly includes a fixed plate, a motor, a main gear, a secondary gear, and a drive rod. The drive rod is hollow. The fixed plate is fixedly installed on the top of the worktable. One end of the drive rod passes through the fixed plate and is rotatably connected to the fixed plate. A triangular chuck is fixedly connected to the end of the drive rod that passes through the fixed plate. The secondary gear is fixedly sleeved on the other end of the drive rod. The main gear is rotatably connected to the fixed plate and meshes with the secondary gear. The motor is fixedly installed on the fixed plate, and the output end of the motor is fixedly connected to the main gear.

[0007] Furthermore, the power assembly includes a support plate and a first electric push rod. The support plate is fixedly installed on the top of the worktable, and the first electric push rod is fixedly installed on the support plate. The output end of the first motor passes through the support plate and slides with it. The fixed rod is fixedly connected to the output end of the first electric push rod.

[0008] Furthermore, the limiting assembly includes a fixed block, a second electric push rod, a slot, a connecting block, and two rotating shafts. The second electric push rod is fixedly installed on the top of the worktable. The fixed block is located on the top of the worktable and is fixedly connected to the output end of the second electric push rod. The fixed block is slidably engaged with the top of the worktable.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This invention uses a triangular chuck to fix the pipe fitting, and a drive assembly to rotate the triangular chuck and the fixed pipe fitting. A power assembly causes a fixing rod to extend into the fixed pipe fitting, and a cutting assembly cuts the fixed pipe fitting, causing the cut pipe fitting to fall onto the fixing rod. The power assembly then moves the fixed rod, which in turn moves the pipe fitting that has fallen onto the fixing rod. When the pipe fitting reaches the second baffle, it contacts and blocks the second baffle. When the fixing rod is no longer in contact with the second baffle, the cut pipe fitting falls onto the feed plate and rolls along the inclined feed plate into a pre-prepared collection box. This automatic collection of the cut pipe fitting eliminates the need for manual collection. Attached Figure Description

[0018] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0019] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 4 The present invention will be further described below.

[0020] This utility model discloses a stainless steel pipe cutting device, including a worktable 1, a triangular chuck 2, and a fixing rod 3. A drive assembly 4 is provided on the top of the worktable 1 to drive the triangular chuck 2 to rotate. The triangular chuck 2 is connected to the drive assembly 4. A cutting assembly 5 and a limiting assembly 6 are provided on the top of the worktable 1 to move horizontally along the top of the worktable 1. A power assembly 7 is provided on the top of the worktable 1 to drive the fixing rod 3 to move horizontally. The limiting assembly 6 and the cutting assembly 5 are symmetrically arranged and located between the drive assembly 4 and the power assembly 7. A feeding assembly 8 is provided between the cutting assembly 5 and the power assembly 7. The feeding assembly 8 is fixedly connected to the top of the worktable 1. The fixing rod 3 passes through the feeding assembly 8 and slides with the feeding assembly 8. The fixing rod 3 is connected to the power assembly 7.

[0021] In this implementation scheme, during use, the operator passes the circular pipe through the drive assembly 4 and the triangular chuck 2, and fixes the pipe using the triangular chuck 2. The drive assembly 4 then rotates the triangular chuck 2 and the fixed pipe. At this time, the power assembly 7 moves the fixing rod 3 towards the pipe, causing the fixing rod 3 to extend into the pipe without contacting the inner wall of the pipe. Simultaneously, the limiting assembly 6 moves along the top of the worktable 1 and contacts the rotating pipe. At the same time, the cutting assembly 5 moves along the top of the worktable 1 towards the pipe and contacts the rotating... The pipe fitting is cut, and the cut pipe fitting falls onto the fixed rod 3. At this time, the cutting component 5 and the limiting component 6 return to the initial position. The driving component 4 drives the triangular chuck 2 and the fixed pipe fitting to stop rotating. At this time, the power component 7 drives the fixed rod 3 and the pipe fitting that fell on the fixed rod 3 away from the triangular chuck 2 and return to the initial position. During the movement, the pipe fitting that fell on the fixed rod 3 comes into contact with the feeding component 8 and is blocked by the feeding component 8. The pipe fitting on the fixed rod 3 will slide down the fixed rod 3 and into the feeding component 8.

[0022] Specifically, the drive assembly 4 includes a fixed plate 401, a motor 402, a main gear 403, a secondary gear 404, and a drive rod 405. The drive rod 405 is hollow. The fixed plate 401 is fixedly installed on the top of the workbench 1. One end of the drive rod 405 passes through the fixed plate 401 and is rotatably connected to the fixed plate 401. The triangular chuck 2 is fixedly connected to the end of the drive rod 405 that passes through the fixed plate 401. The secondary gear 404 is fixedly sleeved on the other end of the drive rod 405. The main gear 403 is rotatably connected to the fixed plate 401 and meshes with the secondary gear 404. The motor 402 is fixedly installed on the fixed plate 401, and the output end of the motor 402 is fixedly connected to the main gear 403.

[0023] In this implementation scheme, during use, the worker passes the pipe through the inside of the power rod 405 and the triangular chuck 2, and clamps and fixes the pipe using the triangular chuck 2. The triangular chuck 2 is an existing device and will not be explained here. This allows the part of the pipe to be cut to extend to the cutting assembly 5. When it is necessary to cut the pipe, the motor 402 drives the main gear 403 to rotate, the main gear 403 drives the secondary gear 404 to rotate, the secondary gear 404 drives the power rod 405 to rotate, and the power rod 405 drives the triangular chuck 2 to rotate. The fixed pipe is rotated through the triangular chuck 2. When the cutting is completed, the motor 402 stops working.

[0024] Specifically, the power assembly 7 includes a support plate 701 and a first electric push rod 702. The support plate 701 is fixedly installed on the top of the workbench 1, and the first electric push rod 702 is fixedly installed on the support plate 701. The output end of the first motor 402 passes through the support plate 701 and slides with the support plate 701. The fixed rod 3 is fixedly connected to the output end of the first electric push rod 702.

[0025] In this embodiment, once the pipe fitting is fixed, the first electric push rod 702 pushes the fixing rod 3 towards the pipe fitting, causing the fixing rod 3 to extend into the pipe fitting. When the cut pipe fitting falls onto the fixing rod 3, the first electric push rod 702 moves the fixing rod 3 and the pipe fitting on the fixing rod 3 away from the triangular chuck 2 and back to the initial position. The first electric push rod 702 has a multi-section structure.

[0026] Specifically, the limiting component 6 includes a fixing block 601, a second electric push rod 602, a slot 603, a connecting block 604, and two rotating shafts 605. The second electric push rod 602 is fixedly installed on the top of the worktable 1. The fixing block 601 is located on the top of the worktable 1 and is fixedly connected to the output end of the second electric push rod 602. The fixing block 601 is slidably engaged with the top of the worktable 1. The slot 603 is opened on the fixing block 601. The connecting block 604 is slidably disposed in the slot 603 and is fixed to the fixing block 601 by bolts. The two rotating shafts 605 are symmetrically arranged on the connecting block 604.

[0027] In this embodiment, when the pipe fitting is fixed, the second electric push rod 602 drives the fixing block 601 to move along the top of the workbench 1 toward the fixed pipe fitting. The movement of the fixing block 601 drives the connecting block 604 and the two rotating shafts 605 to move, so that the two rotating shafts 605 contact the fixed pipe fitting. The fixed pipe fitting is located between the two rotating shafts 605. When the fixed pipe fitting rotates and is cut, the rotating pipe fitting drives the two rotating shafts 605 to rotate. The two rotating shafts 605 ensure that the pipe fitting is not misaligned when it is cut. When the cutting is completed, the second electric push rod 602 drives the connecting block 604 and the two rotating shafts 605 to move, so that the pipe fitting is not misaligned when it is cut. When the cutting is completed, the second electric push rod 602 drives the connecting block 604 to move along the top of the workbench 1 toward the fixed pipe fitting. The push rod 602 drives the fixed block 601 away from the triangular chuck 2. The fixed block 601 drives the two rotating shafts 605 to move synchronously. When encountering pipes with different diameters, the bolt connection between the connecting block 604 and the fixed block 601 is loosened, and the connecting block 604 is pulled out from the slot 603. The connecting block 604 drives the two rotating shafts 605 to move synchronously. At this time, the operator replaces the rotating shaft 605 with a new one that is compatible with the new one. The operator then inserts the new connecting block 604 into the slot 603 and connects the connecting block 604 to the fixed block 601 with bolts.

[0028] Specifically, the cutting assembly 5 includes a cutting tool 501 and a third electric push rod 502. The cutting tool 501 is slidably disposed on the top of the worktable 1, and the third electric push rod 502 is fixedly installed on the top of the worktable 1. The output end of the third electric push rod 502 is fixedly connected to the cutting tool 501.

[0029] In this embodiment, when the fixed pipe rotates, the third electric push rod 502 pushes the cutting tool 501 to move toward the rotating pipe, so that the cutting tool 501 contacts the surface of the pipe and cuts the pipe. The cutting tool 501 will not contact the fixed rod 3. When the cutting is completed, the third electric push rod 502 drives the cutting tool 501 away from the pipe and returns to the initial state.

[0030] Specifically, the feeding assembly 8 includes a feeding plate 801, a first baffle 802, and a second baffle 803. The feeding plate 801 is fixedly installed on the workbench 1 and is inclined. The first baffle 802 and the second baffle 803 are symmetrically fixedly installed on the top of the feeding plate 801. The fixing rod 3 passes through the second baffle 803 and slides with the second baffle 803.

[0031] In this embodiment, when the fixing rod 3 moves the pipe fitting that has fallen on the fixing rod 3, when it moves to the second baffle 803, the cut pipe fitting contacts the second baffle 803 and blocks the second baffle 803. When the fixing rod 3 no longer contacts the second baffle 803, the cut pipe fitting falls onto the feeding plate 801 and rolls along the inclined feeding plate 801 into the pre-prepared collection box. The cut pipe fitting can be automatically collected without manual collection.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
