Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to a cutting device for welding pipe processing. Background Art

[0002] A cutting device is a mechanical device used to separate materials. It is widely used in industrial production and processing to cut workpieces or materials into the desired size and shape. The following will discuss the various types of cutting devices and their characteristics in detail: Laser cutting machines are known for their high efficiency and high precision. This type of cutting device uses a high-power density laser beam to irradiate the surface of the workpiece to reach the melting point or boiling point, and high-pressure gas then blows away the molten metal to complete the cutting process. Plasma cutting machines use high-temperature plasma arcs to penetrate metals to achieve rapid cutting. Mechanical cutting equipment such as shears and saws rely on physical tools to apply force to the material to achieve cutting. This type of equipment is simple to operate and low-cost, but there are certain limitations on cutting thickness and quality.

[0003] The cutting device for welded pipe processing is a device specially used for welding pipe cutting, which aims to improve cutting efficiency and precision while solving the various limitations and challenges in traditional cutting methods. In the production process of welded pipes, since the welded pipes after forming are generally long, they need to be accurately cut to meet different usage requirements. However, traditional cutting devices have many limitations, such as the inability to effectively fix welded pipes of different diameters, the need to measure and mark in advance, and the inability to cut in batches. These problems seriously affect production efficiency and product quality.

[0004] For example, the invention patent with the announcement number CN113579309A provides a pressurized pipeline drilling device, which realizes pipeline drilling and diversion without stopping the water supply through the water diversion seat, ball valve, sealing connection assembly and drilling mechanism. However, when drilling a pipeline, the drilling mechanism is likely to push the pipeline, causing the pipeline to deform, and when drilling a thin pipeline, the pipeline is easily deformed by the cutting force, which leads to inaccurate cutting size.

[0071] The first sliding rod 170 and the second sliding rod are both vertically arranged, and the first sliding rod 170 and the second sliding rod are respectively arranged at the two ends of the bidirectional threaded rod 114, and the first sliding rod 170 and the second sliding rod are both threadedly matched with the bidirectional threaded rod 114. The first clamping plate 115 is fixedly arranged on the first sliding rod 170, and the second clamping plate 116 is fixedly arranged on the second sliding rod.

[0072] The clamping handle 1111 is rotated forward, and the clamping handle 1111 drives the second gear 112 to rotate, and the second gear 112 drives the third gear 113 to rotate, and the third gear 113 drives the bidirectional threaded rod 114 to rotate synchronously, and the bidirectional threaded rod 114 drives the first sliding rod 170 and the second sliding rod to move when rotating, and the first sliding rod 170 and the second sliding rod drive the first clamping plate 115 and the second clamping plate 116 to move synchronously, and the first clamping plate 115 and the second clamping plate 116 move away from each other. The welding pipe 103 is placed between the first clamping plate 115 and the second clamping plate 116. The clamping handle 1111 is rotated backward, so that the first clamping plate 115 and the second clamping plate 116 are close to each other and clamp the welding pipe 103.

[0073] In this embodiment, a measuring disc 102 is fixedly disposed on the support frame 101. As required, the support plate 104 is rotated, the measuring disc 102 is observed, and the angle required for deflection is determined.

[0074] Working process: forward rotation of the clamping handle 1111, the clamping handle 1111 drives the second gear 112 to rotate, the second gear 112 drives the third gear 113 to rotate, the third gear 113 drives the bidirectional threaded rod 114 to rotate synchronously, the bidirectional threaded rod 114 drives the first sliding rod 170 and the second sliding rod to move when rotating, the first sliding rod 170 and the second sliding rod drive the first clamping plate 115 and the second clamping plate 116 to move synchronously, and the first clamping plate 115 and the second clamping plate 116 move away from each other. Place the welding pipe 103 between the first clamping plate 115 and the second clamping plate 116. Reverse rotation of the clamping handle 1111 makes the first clamping plate 115 and the second clamping plate 116 approach each other and clamp the welding pipe 103.

[0075] As required, the support plate 104 is rotated, and the measuring disk 102 is observed to determine the angle required for deflection.

[0076] According to the diameter of the welding pipe 103, the first adjusting ring 118 is manually rotated, and the first adjusting ring 118 rotates relative to the first rotating disk 117. Under the mutual cooperation of the first slide groove 1171 and the second slide groove 120 where each first connecting rod 1212 is located, the first adjusting ring 118 pushes the first tool 121 to move in the direction away from the axis of the first rotating disk 117, thereby increasing the area of ​​the circle surrounded by multiple first tools 121, so that the first tool 121 cuts a suitable notch.

[0077] When the first adjusting ring 118 rotates relative to the first rotating disk 117, since the first rotating disk 117 can only rotate relative to the first mounting tube 150 and cannot move, the first adjusting ring 118 can also only rotate relative to the first rotating disk 117 and cannot move. Moreover, since the first protrusion 1181 on the first adjusting ring 118 is arranged in the spiral groove in the positioning drill bit 122, when the first adjusting ring 118 rotates, it drives the positioning drill bit 122 to move a distance toward the direction close to the welding pipe 103.

[0078] The motor is started, and the motor drives the positioning drill bit 122 to rotate through the first transmission shaft 1091, and the positioning drill bit 122 drives the first rotating disk 117 to rotate synchronously. At the same time, due to the first protrusion 1181 being arranged in the spiral groove and the action of the first connecting rod 1212, the first adjusting ring 118 and the first rotating disk 117 rotate synchronously. The push rod 110 is pushed to gradually approach the welding pipe 103, and the push rod 110 drives the first base 106 to gradually approach the welding pipe 103. Due to the meshing of the first rack 107, the second rack and the first gear 105, the second base 140 is driven to gradually approach the welding pipe 103.

[0079] The square drill 1221 first passes through the two walls of the welding pipe 103, and at this time, the first tool 121 has not yet contacted the welding pipe 103. After the square drill 1221 passes through the two walls of the welding pipe 103, the motor is manually controlled to decelerate, the square drill 1221 contacts the square hole rod 136, and is inserted into the square hole 1361. After the square drill 1221 is inserted into the square hole 1361, the motor is manually controlled to accelerate so that the square drill 1221 is inserted into the square hole 1361.

[0080] The square drill bit 1221 drives the square hole rod 136 to rotate synchronously, and there is axial movement between the square drill bit 1221 and the square hole rod 136. When the square hole rod 136 rotates, it drives the second bevel gear 135 to rotate synchronously, and the second bevel gear 135 drives the first bevel gear 133 to rotate through the third bevel gear 137, and the rotation directions of the first bevel gear 133 and the second bevel gear 135 are opposite. The first bevel gear 133 drives the second rotating disk 125 to rotate synchronously, and the second rotating disk 125 drives the second tool 127 and the second adjustment ring 124 to rotate synchronously. And under the action of multiple support rods 1331, the adjusting rotating tube 130 is driven to rotate synchronously, and when the adjusting rotating tube 130 rotates, it drives multiple second wedges 129 to rotate synchronously.

[0081] As the push rod 110 moves, the square drill bit 1221 continues to penetrate into the square hole 1361, and after contacting the adjusting sliding rod 131, pushes the adjusting sliding rod 131 to move in the direction away from the welding pipe 103. The adjusting sliding rod 131 pushes the adjusting rotating tube 130 to move synchronously through the spring 1311. Under the action of the first inclined surface on the first wedge block 128 and the second inclined surface on the second wedge block 129, the plurality of second cutters 127 move in the direction away from the center of the second rotating disk 125, and the area surrounded by the plurality of second cutters 127 is the same as the area surrounded by the plurality of first cutters 121. The greater the rotation angle of the first adjusting ring 118, the larger the area surrounded by the plurality of first cutters 121, the longer the distance the positioning drill bit 122 moves toward the welding pipe 103, and the more the positioning drill bit 122 pushes the adjusting sliding rod 131 to move in the direction away from the welding pipe 103, thereby making the area surrounded by the plurality of second cutters 127 larger. By adjusting the first tool 121, the area of ​​the circle enclosed by the second tool 127 and the first tool 121 is made the same, which saves costs and ensures that the area cut by the first tool 121 and the second tool 127 is the same, and the cutting accuracy is higher.

[0082] After that, the push rod 123 is rotated, and the cam 1231 pushes the second adjustment ring 124 to move toward the second rotating disk 125. The second adjustment ring 124 and the second rotating disk 125 clamp the third block on the second connecting rod to prevent the second cutter 127 from resetting. Finally, the push rod 110 continues to feed, and the first cutter 121 and the second cutter 127 simultaneously approach the welded pipe 103 and rotate in opposite directions. After the cutting is completed, the welded pipe 103 is removed, and the cutting device for the welded pipe processing is reset.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
