Description

Technical Field

[0001] This utility model relates to the field of gas pipeline processing technology, and in particular to a bending device for processing gas metal-clad pipes. Background Technology

[0002] Gas metal-coated hoses are special hoses used to connect indoor gas pipelines to gas appliances such as stoves and water heaters. The full name is metal-coated hose for gas appliance connection. It adopts a three-layer structure design. The inner layer is made of corrosion-resistant rubber or plastic material, which serves as the main channel for gas transmission. The middle layer is a metal sheath made of stainless steel wire mesh or armored steel strip, which plays a role in pressure resistance and rodent protection. The outer layer is a flame-retardant PVC or PE coating layer, which protects the pipeline from corrosive substances in kitchen fumes.

[0003] In gas supply equipment, metal-clad pipes are widely used in gas transmission pipelines due to their excellent corrosion resistance, pressure resistance, and sealing properties. During gas pipeline laying and installation projects, it is often necessary to bend the metal-clad pipes according to the specific installation environment and spatial layout to meet the requirements of the pipeline route. However, existing bending methods for clad pipes usually involve using pipe wrenches and pipe benders. This method makes it difficult to guarantee the bending quality of the clad pipes, resulting in problems such as pipe deformation, wrinkles, and cracks, which affect the service life and safety of the pipeline. At the same time, existing bending equipment can only bend clad pipes of specific specifications and cannot be flexibly adjusted according to clad pipes of different specifications and processing requirements, resulting in poor equipment versatility.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1:

[0029] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a bending device for processing gas metal-coated pipes, including a base plate 1, a vertical plate frame 2 fixed on the top of the base plate 1, a fixing frame 3 provided on one side of the vertical plate frame 2, a placement block 4 installed on one side of the fixing frame 3, and a U-shaped groove opened on the top of the placement block 4. The coated pipe body 5 is provided on the top of the placement block 4, and a fixing member 6 is provided on the top of the fixing frame 3.

[0030] The base plate 1 serves as the foundation of the entire equipment, providing stable support and a solid foundation for other components, ensuring the stability and integrity of the equipment during operation. The upright frame 2 provides an installation position for the mounting frame 17 and is an important component of the overall equipment structure, maintaining the frame structure. The fixing frame 3 serves as the mounting carrier for the placement block 4 and the fixing component 6, providing a support platform for the placement, fixing, and bending operations of the coated pipe body 5. The placement block 4 is used to place the coated pipe body 5, providing initial positioning and placement for the coated pipe body 5, facilitating subsequent bending operations. The coated pipe body 5 is the object processed by the equipment, and the bending process is completed through a series of operations to meet the usage requirements of the gas pipeline. The fixing component 6 is used to fix the coated pipe body 5 placed on the placement block 4, preventing it from moving during the bending process and ensuring the quality of processing.

[0031] A mounting plate 7 is installed on one side of the placement block 4. A pressure rod frame 8 is rotatably connected to one side of the mounting plate 7. A cylinder 24 is rotatably connected to the top of the base plate 1. The piston rod of the cylinder 24 is rotatably connected to the inner wall of the pressure rod frame 8 through a connecting rod. A limit roller 9 and a pressure roller 10 are respectively installed on the inner wall of the pressure rod frame 8 through mounting bolts. The outer side of the pressure roller 10 is slidably connected to the inner wall of the pressure rod frame 8. An adjustment component 11 is provided on one side of the pressure rod frame 8.

[0032] The mounting plate 7 provides a rotatable support point for the pressure rod frame 8, allowing it to rotate around the mounting plate 7. This rotation drives the limiting roller 9 and pressure roller 10 to bend the coated tube body 5. The pressure rod frame 8 is the main actuator for the bending operation. Its rotation causes the limiting roller 9 and pressure roller 10 to apply pressure to the coated tube body 5, thus achieving the bending process. The cylinder 24, through the extension and retraction of its piston rod, drives the pressure rod frame 8 downwards. The limiting roller 9, in conjunction with the pressure roller 10, limits and guides the coated tube body 5 during bending, preventing it from shifting and ensuring bending quality. The adjusting component 11 is used to adjust the pressure roller. Position 10 allows for adjustment of different bending forces and angles of the coated tube body 5 to adapt to coated tube bodies 5 with different specifications and processing requirements. It should be noted that the cylinder 24 is used in conjunction with an air compressor, an air tank, a filter pressure reducing valve, a directional control valve, and a flow control valve. During use, the air compressor compresses ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure, then delivers it to the control valve through an air pipe. The directional control valve switches the airflow channel according to an electrical signal to determine the extension and retraction direction of the cylinder 24. The flow control valve adjusts the airflow speed and controls the movement speed of the cylinder 24. Compressed air enters the rod chamber or rodless chamber of the cylinder 24, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion.

[0033] The adjustment assembly 11 includes a second limiting seat 111 installed on one side of the pressure rod frame 8. The inner wall of the second limiting seat 111 is rotatably connected to a push block 112 and a handle 113, and the inner wall of the push block 112 is rotatably connected to the outer side of the handle 113. The outer side of the push block 112 is rotatably connected to a top rod 114, and the other end of the top rod 114 is sleeved on the outer side of the pressure roller 10 through a collar.

[0034] The second limiting seat 111 is provided as a support point for the rotatable connection between the push block 112 and the handle 113, allowing the push block 112 and the handle 113 to rotate relative to each other. Since the push block 112 is rotatably connected to the handle 113, and a push rod 114 is rotatably connected to its outer side, the rotation of the handle 113 drives the push block 112 to move, which in turn pushes the push rod 114 to move, thus adjusting the position of the pressure roller 10. The handle 113 allows for convenient control of the movement of the push block 112, thereby enabling the adjustment of the pressure roller 10's position. The push rod 114, pushed by the push block 112, drives the pressure roller 10 to move, achieving position adjustment. When adjusting the position of the pressure roller 10, first loosen the mounting bolts used to fix the pressure roller 10, and then the operator manually... Rotating handle 113 causes the push block 112 to rotate, as its inner wall is rotatably connected to the outer side of handle 113 and its outer side is rotatably connected to the second limit seat 111. Rotating handle 113 drives push block 112 to rotate, which in turn pushes top rod 114. Top rod 114 pulls pressure roller 10 along the inner wall of pressure rod frame 8 via a collar, thus changing the distance between pressure roller 10 and limit roller 9. After the position of pressure roller 10 is adjusted, tighten the mounting bolts to fix it, enabling the equipment to adapt to the bending requirements of different specifications of the coated tube body 5. This ensures that pressure roller 10 can apply appropriate pressure to the coated tube body 5 during bending. Using adjustment component 11 to adjust the position of pressure roller 10 is more labor-saving than manually adjusting it directly.

[0035] Example 2:

[0036] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the fixing component 6 includes a first limiting seat 61 installed on the top of the fixing frame 3. The inner wall of the first limiting seat 61 is rotatably connected to a movable rod 62 and a handle 63, and the outer side of the movable rod 62 is rotatably connected to the inner wall of the handle 63. The inner wall of the movable rod 62 is slidably connected to a pressing block 64 for fixing the covering tube body 5.

[0038] The first limiting seat 61 is provided as a support point for the rotatable connection between the movable rod 62 and the handle 63, allowing the movable rod 62 and the handle 63 to rotate relative to each other. Since the movable rod 62 is rotatably connected to the handle 63, and its inner wall is slidably connected to the pressing block 64, the rotation and movement of the movable rod 62 drives the pressing block 64 to perform the fixing or loosening operation of the covered tube body 5. By operating the handle 63, the movement of the movable rod 62 can be easily controlled, thereby enabling the operation of the pressing block 64, thus facilitating the fixing and disassembly of the covered tube body 5. The pressing block 64 is designed to directly contact and press the covered tube body 5, achieving the fixing of the covered tube body 5. To prevent movement during processing, when it is necessary to fix the coated tube body 5, first place the coated tube body 5 in the U-shaped groove on the top of the placement block 4, and then the worker holds the handle 63 and rotates it. Since the outer side of the movable rod 62 is rotatably connected to the inner wall of the handle 63, and the inner wall of the movable rod 62 is slidably connected to the pressing block 64, the rotation of the handle 63 can drive the movable rod 62 to move, thereby causing the pressing block 64 to move downward under the action of the movable rod 62. When the pressing block 64 moves down to contact the coated tube body 5 and applies sufficient pressure, the coated tube body 5 is firmly fixed on the placement block 4, preventing displacement of the coated tube body 5 during bending.

[0039] Specifically, a scale plate 12 is fixed to the outer side of the fixing frame 3, and an L-shaped plate 13 is slidably connected to the inner wall of the fixing frame 3. A plug rod 14 is installed on one side of the L-shaped plate 13, and one end of the plug rod 14 is inserted into one end of the covering tube body 5.

[0040] The scale plate 12 is used to display the processing dimensions or position information of the coated tube body 5. The operator can control the bending position and length of the coated tube body 5 according to the scale on the scale plate 12, thereby improving the processing quality of the coated tube body 5. By sliding the L-shaped plate 13 on the inner wall of the fixing frame 3, the position of the insertion rod 14 can be adjusted, thereby positioning and fixing one end of the coated tube body 5, ensuring the stability and processing quality of the coated tube during the processing. The insertion rod 14 is used to fix one end of the coated tube body 5 to prevent the one end of the coated tube body 5 from moving during the bending process, ensuring the smooth progress of the processing.

[0041] Specifically, a mounting block 15 is bolted to one side of the fixing frame 3, and a limiting rod 16 for limiting the pressure rod frame 8 is slidably connected to the inner wall of the mounting block 15.

[0042] Mounting block 15 is bolted to one side of fixed frame 3 to provide an installation position for limit rod 16, so that limit rod 16 can be stably installed on the equipment. The limit rod 16 is set to limit the pressure rod frame 8 to prevent the pressure rod frame 8 from exceeding the set range during rotation, thus ensuring the safe operation of the equipment and the processing quality.

[0043] Example 3:

[0044] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, a mounting bracket 17 is installed on one side of the upright frame 2, and a slide rail 18 is installed on one side of the mounting bracket 17.

[0046] The mounting bracket 17 is provided to provide an installation position for the slide rail 18 and the first clamping block 19, and serves to connect and support the fixing frame 3. The slide rail 18 is provided to provide a sliding connection track for the second clamping block 20, so that the second clamping block 20 can slide on the slide rail 18, thereby realizing the clamping and releasing operation of the fixing plate 21, and facilitating the installation and adjustment of the fixing frame 3.

[0047] Specifically, a first clamping block 19 is fixed to one side of the mounting bracket 17, a second clamping block 20 is slidably connected to the outside of the slide rail 18, a fixing plate 21 is clamped and fixed between the first clamping block 19 and the second clamping block 20, and one side of the fixing plate 21 is fixedly connected to the back of the fixing bracket 3.

[0048] The first clamping block 19, in conjunction with the second clamping block 20, is used to clamp the fixing plate 21. Through the combined action of the first clamping block 20 and the second clamping block 20, the fixing frame 3 is fixed to the equipment, ensuring the stability of the fixing frame 3. The second clamping block 20 slides on the slide rail 18, and can move closer to or further away from the first clamping block 19 to achieve clamping and releasing operations on the fixing plate 21. The fixing plate 21 serves to connect the fixing frame 3 and the mounting bracket 17, and stably installs the fixing frame 3 on the equipment.

[0049] Specifically, a screw 22 is rotatably connected to the inner wall of the slide rail 18, and the outer side of the screw 22 is threadedly connected to the inner wall of the second clamping block 20. A rocker arm 23 is fixed to the other end of the screw 22.

[0050] By rotating the screw 22, the second clamping block 20 can be driven to slide on the slide rail 18, thereby adjusting the position of the second clamping block 20. This facilitates clamping and releasing operations on the fixed plate 21. The rocker arm 23 allows for easy rotation of the screw 22, thereby adjusting the position of the second clamping block 20. The operation is simple and convenient, improving the operability and work efficiency of the equipment. It should be noted that the rocker arm 23 will not touch the cylinder 24 during rotation, thus affecting the normal operation of the cylinder 24.

[0051] Working principle: When this bending equipment for processing gas metal-coated pipes is in operation, first, the bending equipment is installed. The fixing plate 21 on one side of the fixing frame 3 is placed between the first clamping block 19 and the second clamping block 20. Then, the rocker arm 23 is manually rotated. The rocker arm 23 drives the screw 22 to rotate. The screw 22 drives the second clamping block 20 to slide on the slide rail 18 and approach the first clamping block 19, clamping the fixing plate 21, thereby ensuring the stability of the bending equipment. Then, the coated pipe body 5 to be processed is placed in the U-shaped groove on the top of the placement block 4. At this time, the scale plate 12 is observed, and the processing requirements are adjusted accordingly. Determine the bending position and length of the coated tube body 5, then slide the L-shaped plate 13 to insert the insertion rod 14 into one end of the coated tube body 5. After adjusting the position of the coated tube body 5, fix it by tightening the bolts inside the L-shaped plate 13, thereby positioning and fixing the coated tube body 5 to prevent one end from moving during processing. Next, operate the fixing part 6 to fix the coated tube body 5. The worker holds the handle 63 and rotates it. Because the outer side of the movable rod 62 is rotatably connected to the inner wall of the handle 63, and the inner wall of the movable rod 62 is slidably connected to the pressing block 64, the handle 63... Rotation drives the movable rod 62 to move, thereby causing the pressing block 64 to move downwards. When the pressing block 64 moves down to contact the coating tube body 5 and applies sufficient pressure, the coating tube body 5 is firmly fixed on the placement block 4, preventing displacement of the coating tube body 5 during bending. Then, according to the specifications and processing requirements of the coating tube body 5, when adjusting the position of the pressure roller 10, first loosen the mounting bolts used to fix the pressure roller 10, and then manually rotate the handle 113. Because the inner wall of the push block 112 is rotatably connected to the outer side of the handle 113, and the push block 112 is connected to the second limit seat... 111 is rotated. Rotating handle 113 drives push block 112 to rotate. Push block 112 rotates and pushes top rod 114. Top rod 114 pulls pressure roller 10 to slide on the inner wall of pressure rod frame 8 through collar, thereby changing the distance between pressure roller 10 and limit roller 9. After adjustment, tighten the mounting bolts to fix pressure roller 10. Finally, start cylinder 24. Cylinder 24 drives pressure rod frame 8 to press down. At this time, pressure rod frame 8 drives limit roller 9 to rotate along the axis of pressure roller 10, applying pressure to the coated tube body 5, thereby realizing the bending work of coated tube body 5.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
