Description

Technical Field

[0001] This utility model belongs to the field of stainless steel composite pipe processing technology, and in particular relates to a cutting device for large-diameter thin-walled stainless steel composite pipes. Background Technology

[0002] Patent CN203781328U discloses an automatic feeding device in a steel pipe cutting machine. The device uses a cylinder to push the steel pipe, causing it to roll along a guide plate into a holding frame, thus completing the automatic feeding of the steel pipe.

[0003] However, for large-diameter thin-walled stainless steel composite pipes, their large diameter and thin walls result in relatively weak resistance to external pressure. When using the aforementioned feeding device, the rapid sliding of the stainless steel composite pipe generates significant kinetic energy, causing a large impact force when the pipes come into contact, which makes the pipes prone to deformation.

[0004] Therefore, it is necessary to improve the existing stainless steel composite pipe cutting equipment. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a cutting device for large-diameter thin-walled stainless steel composite pipes, which reduces the probability of deformation during the pipe cutting process.

[0006] To achieve the above objectives, the specific technical solution of the large-diameter thin-walled stainless steel composite pipe cutting equipment of this utility model is as follows:

[0007] A cutting device for large-diameter thin-walled stainless steel composite pipes includes a cutting table, a support is provided on one side of the cutting table, the top surface of the cutting table is an inclined surface, the top surface of the support is a horizontal surface and smoothly transitions to the bottom end of the inclined surface, and multiple elastic buffer strips are suspended directly above the support.

[0008] Preferably, the top surface of the cutting table is provided with a vertical lifting channel, a lifting seat is slidably fitted in the lifting channel, and a support wheel is provided on the top surface of the lifting seat.

[0009] Preferably, multiple lifting channels are arranged along the length of the cutting table, and each lifting channel is slidably provided with a lifting seat.

[0010] Preferably, the height of the inclined surface gradually decreases along the width direction of the cutting table, and multiple buffer strips are arranged along the width direction of the cutting table.

[0011] Preferably, the support includes a top beam extending horizontally along the width direction of the cutting table, one end of the top beam being fixedly connected to the cutting table, and the other end of the top beam being fixedly connected to a vertically extending support rod.

[0012] Preferably, the inclined surface is covered with an adhesive layer.

[0013] Preferably, a buffer pad is provided on the top surface of the top beam.

[0014] Preferably, a hanging bracket is provided directly above the top beam, the hanging bracket is parallel to the top beam, and multiple openings are equally spaced on the hanging bracket along its own extension direction. The top of the buffer strip is fixedly connected to a hook that matches the opening.

[0015] Preferably, the support rod is a hollow tubular structure, and a plug rod is vertically slidably arranged on the inner side of the support rod. The top end of the plug rod is fixedly connected to one end of the bracket, and the support rod is provided with a locking element.

[0016] The large-diameter thin-walled stainless steel composite pipe cutting equipment of this utility model has the following advantages: the cut pipe rolls down the inclined surface onto the support, and the resistance generated by the buffer strips suspended above the support slows down the pipe, thereby reducing the impact force on the pipe and reducing the probability of pipe deformation; at the same time, the hanging buffer strips can also be distributed between two adjacent pipes to isolate and buffer the two pipes, reducing mutual wear between the pipes.

Detailed Implementation

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the cutting equipment and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0026] like Figure 1 and 2 As shown, a cutting device for large-diameter thin-walled stainless steel composite pipes includes a cutting table 3, a support 4 on one side of the cutting table 3, the top surface of the cutting table 3 is an inclined surface 301, the top surface of the support 4 is a horizontal surface and smoothly transitions to the bottom end of the inclined surface 301, and multiple elastic buffer strips 6 are suspended directly above the support 4.

[0027] The aforementioned cutting equipment is suitable for cutting stainless steel composite pipes. It can buffer and protect the pipes during the cutting process, reducing the impact force and the probability of deformation and wear. The cutting equipment includes a conveying device 1, a cutting device 2, and a cutting table arranged sequentially along the pipe conveying direction. The conveying device 1 is used to convey the pipes and includes clamping components and translational / rotating components. The clamping components clamp and fix the pipes, while the translational / rotating components push the pipes forward for conveying and rotation. When the pipes are conveyed to the cutting table 3, the cutting device 2 cuts them. The cutting device 2 is a laser cutter equipped with a three-axis moving platform. The cut pipes roll down the inclined surface 301 onto the support 4 for further processing. Temporarily stored; the buffer strip 6 can be a rubber strip. The rubber buffer strip 6 has a large coefficient of friction, good elasticity and softness. The top of the buffer strip 6 is suspended and allowed to hang naturally. The buffer strip 6 is distributed on the rolling path of the pipe. When the two come into contact, the friction between the buffer strip 6 and the pipe can decelerate the pipe, thereby reducing the impact force on the pipe and reducing the probability of pipe deformation. When the pipe is stationary on the support 4, the hanging buffer strip 6 is distributed on both sides of the pipe. When the subsequent pipe rolls down, the buffer strip 6 is located between the two adjacent pipes and plays a separating role. While playing a buffering role, it can also reduce the mutual wear between the two pipes, thereby improving the quality of the pipe cut by the cutting equipment.

[0028] Further improvements include, for example Figure 3 and 6As shown, the top surface of the cutting table 3 is provided with a vertical lifting channel 302, and a lifting seat 701 is slidably fitted inside the lifting channel 302. The top surface of the lifting seat 701 is provided with a support wheel 7. Multiple lifting channels 302 are arranged along the length of the cutting table 3, and a lifting seat 701 is slidably installed inside each lifting channel 302. In this cutting equipment, the conveying direction of the stainless steel composite pipe is consistent with the length direction of the cutting table 3. A hydraulic cylinder is installed inside the lifting channel 302, which pushes the lifting seat 701 to rise and fall inside the lifting channel 302. When the conveying device 1 delivers the front end of the pipe to the top of the cutting table 3, the lifting seat 701 rises, so that the two support wheels 7 on the lifting seat 701 are rolled and connected to the pipe, thereby achieving the support function for the pipe. Furthermore, by setting multiple lifting seats 701 for independent lifting, the pipe can be supported at multiple points from different parts of the pipe, improving the stability of the pipe during cutting and reducing the probability of pipe deformation. During the rotation of the pipe, the support wheels 7 can reduce the resistance of the pipe and improve its rotation smoothness. Finally, the cut pipe is stably held above the cutting table 3 under the support of the support wheels 7. As the lifting seat 701 slowly descends and is retracted into the lifting channel 302, the pipe is transferred to the inclined surface 301 and rolls down along the inclined surface 301.

[0029] Further improvements include, for example Figure 2 As shown, the height of the inclined surface 301 gradually decreases along the width direction of the cutting table 3, and multiple buffer strips 6 are arranged along the width direction of the cutting table 3. The multiple buffer strips 6 are distributed along the rolling path of the pipe, which can achieve multiple decelerations of the pipe, improve the deceleration effect, reduce the impact force on the pipe, and reduce the probability of pipe deformation. Furthermore, after the pipe stops rolling, buffer strips 6 are distributed on both the front and rear sides of the rolling direction, thereby isolating adjacent pipes and reducing wear between them.

[0030] Further improvements include, for example Figure 3 As shown, the support 4 includes a top beam 401 extending horizontally along the width direction of the cutting table 3. One end of the top beam 401 is fixedly connected to the cutting table 3, and the other end of the top beam 401 is fixedly connected to a vertically extending support rod 402. Multiple supports 4 are distributed at intervals along the length direction of the cutting table 3. By supporting the pipes with multiple supports 4, the stability between the pipes can be improved, and the spacing between the supports 4 facilitates the hoisting of the pipes, improving the convenience of pipe transfer.

[0031] Further improvements include, for example Figure 3As shown, the inclined surface 301 is covered with an adhesive layer 303. The adhesive layer 303 is silicone tape. The adhesive layer 303 protects the rolling pipe, reduces surface wear, and absorbs impurities from the pipe surface, thus cleaning it. Furthermore, the adhesiveness of the adhesive layer 303 provides resistance to the rolling pipe, controlling its speed. The selected silicone tape is soft, protecting the pipe and reducing wear, and adheres better to the pipe surface, improving cleaning effectiveness. The adhesiveness of the silicone tape is achieved through the physical adsorption between silicone molecules and dirt molecules. This adhesiveness is relatively mild; it picks up dirt without creating strong adhesion to the workpiece surface, thus leaving no glue residue when removing the tape, maintaining the cleanliness of the pipe surface.

[0032] Further improvements include, for example Figure 3 As shown, a buffer pad 404 is provided on the top surface of the top beam 401. The buffer pad 404 is a rubber pad, which allows the buffer pad 404 to play a good buffering role on the pipe and reduce the wear of the pipe.

[0033] Further improvements include, for example Figure 3 and 4 As shown, a bracket 5 is installed directly above the top beam 401. The bracket 5 is parallel to the top beam 401. Multiple openings 501 are evenly spaced along the extension direction of the bracket 5. The top of the buffer strip 6 is fixedly connected to a hook 601 that matches the opening 501. The support rod 402 is a hollow tubular structure. A plug rod 502 is vertically slidably installed on the inner side of the support rod 402. The top of the plug rod 502 is fixedly connected to one end of the bracket 5. The support rod 402 is equipped with a locking element 403. In this cutting equipment, multiple hangers 5 can be installed, allowing for multiple sets of buffer bars 6. By having multiple sets of buffer bars 6 contact different parts of the pipe, the deceleration and buffering effect can be improved. The locking element 403 is a bolt, which allows for the locking and unlocking of the support rod 402 and the insertion rod 502. This allows for adjustment of the height of the insertion rod 502. Height adjustment ensures that the distance between the bottom end of the buffer bar 6 and the top surface of the bracket 4 is less than the radius of the pipe, thus guaranteeing reliable contact between the buffer bar 6 and the pipe and improving the deceleration effect of the buffer bar 6 on the pipe. Furthermore, it ensures... The buffer strip 6 can hang down between two adjacent pipes, thereby separating the two pipes and reducing mutual wear between them. The opening 501 and the hook 601 cooperate to realize the quick installation and removal of the buffer strip 6. By setting the buffer strip 6 in different openings 501, the spacing between the buffer strips 6 and the number of buffer strips 6 can be adjusted. The smaller the spacing and the more buffer strips 6, the greater the resistance to the pipe. However, too much resistance will affect the rolling distance of the pipe. Therefore, it is necessary to reasonably set the number and spacing of the buffer strips 6 to ensure the deceleration effect on the pipe and ensure that the pipe can roll into place.
