Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe production technology, and in particular to a fully automatic wax spraying device for stainless steel pipe production. Background Technology

[0002] In the production of stainless steel pipes, waxing is a crucial step in the polishing process. The wax acts as a lubricant and filler during polishing, ensuring more even contact between the polishing tools and the stainless steel pipe surface, reducing friction, and thus improving polishing efficiency and quality. Appropriate wax can also prevent excessive heat generated during polishing, avoiding surface damage. Currently, most waxing devices for stainless steel pipes on the market use a bracket to fix the wax block, and then a conveyor mechanism transports the stainless steel pipe through the wax block. The drawback of this device is that the fixed wax block can easily lead to uneven waxing, affecting the quality of the waxing process. Utility Model Content

[0003] The purpose of this utility model is to provide a fully automatic wax spraying device for stainless steel pipe production, which addresses the shortcomings of existing technologies. It integrates automatic feeding, automatic wax spraying, and automatic unloading, completely replacing manual operation and significantly improving overall work efficiency.

The power output end of the wax spraying head driving assembly drives and connects to the wax spraying head, and a wax tube is connected to the top of the wax spraying head.

[0005] A further improvement to the above scheme is that the steel pipe rotating assembly includes two parallel rotating steel pipe rollers mounted on the wax spraying machine frame, and a rotating roller drive device for driving the rotating steel pipe rollers to rotate. The power output end of the rotating roller drive device is connected to the rotating steel pipe rollers.

[0006] A further improvement to the above scheme is that the rotating roller drive device is a servo motor.

The plurality of transmission gears are connected to each other by chain transmission, and the power output end of the drive assembly drives and connects to the transmission gears.

[0010] A further improvement to the above solution is that the drive assembly includes a feeding drive motor fixedly mounted on the frame and a drive gear mounted on the power output end of the feeding drive motor. The drive gear and the transmission gear are connected by a chain drive, and the feeding drive motor is driven by the drive gear and the transmission gear.

[0011] A further improvement to the above scheme is that the feeding roller is provided with a limiting part with a gradually increasing radius extending from the middle to both ends.

[0020] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-5 As shown, this utility model provides a fully automatic wax spraying device for stainless steel pipe production, including a feeding mechanism 1 for feeding materials, a discharging mechanism 2 for discharging materials, and a wax spraying mechanism 3 for spraying wax onto the stainless steel pipes. The feeding mechanism 1 is located at the feeding end of the wax spraying mechanism 3, and the discharging mechanism 2 is located at the discharging end of the wax spraying mechanism 3. The feeding mechanism 1 and the discharging mechanism 2 have the same structure. The wax spraying mechanism 3 includes a wax spraying frame 31, a steel pipe rotating assembly 32 mounted on the wax spraying frame 31 for driving the steel pipe to rotate, and a wax spraying head 33 movably mounted above the wax spraying frame 31 along the X-axis and Z-axis directions for driving the wax spraying. The head 33 moves along the X-axis and Z-axis directions. The power output end of the head 34 drives the head 33. The top of the head 33 is connected to the wax tube 331. The steel pipe rotation assembly 32 drives the steel pipe to rotate, so that the head 33 can cover the entire circumference of the steel pipe relatively evenly. The head 33 can move on the X-axis and Z-axis, so that the head 33 can be accurately positioned and moved along the axial direction of the steel pipe to spray, ensuring uniform coverage along the length of the steel pipe. The coordinated movement in the X and Z directions can adapt to steel pipes of different diameters and lengths, achieving more comprehensive coverage.

[0021] In this embodiment, the wax spray head 33 can be set as a conventional air pump type wax spray head 33, which is connected to an external wax source through the wax tube 331. This is a conventional technical means, and this utility model will not elaborate on it.

[0022] In this embodiment, a controller can be set to control the feeding mechanism 1, the unloading mechanism 2, and the wax spraying mechanism 3 to work synchronously. The controller can be a common PLC industrial controller, used to set parameters, monitor operation, etc. This is a conventional technical means, and this utility model will not elaborate on it.

[0023] The steel pipe rotating assembly 32 of this utility model includes two parallel rotating steel pipe rollers 321 mounted on a wax spraying frame 31, and a rotating roller drive device 322 for driving the rotating steel pipe rollers 321 to rotate. The power output end of the rotating roller drive device 322 drives and connects to the rotating steel pipe rollers 321. The double roller design provides a stable support point for the steel pipe, ensuring that the steel pipe rotates smoothly without shaking. At the same time, rotating the steel pipe ensures that the surface of the steel pipe is evenly sprayed with wax.

[0024] The rotating roller drive device 322 of this utility model is a servo motor. The servo motor can precisely control the rotation speed of the rotating roller. The rotation speed can be optimized according to different pipe diameters, different wax liquid characteristics or different wax spraying process requirements to achieve the best wax spraying uniformity and efficiency.

[0025] The present invention relates to a wax spray head drive assembly 34, which includes a wax spray head support frame 341 mounted on a wax spray frame 31, an X-axis guide rail 342 mounted on the wax spray head support frame 341 along the X-axis direction, an X-axis slide block 343 slidably mounted on the X-axis guide rail 342, an X-axis drive device 344 mounted on the wax spray head support frame 341, a Z-axis support 345 mounted on the X-axis slide block 343, a wax spray head support 346 movably mounted on the side of the Z-axis support 345 along the Z-axis direction, and a device mounted on the Z-axis support 345 for driving the wax spray head support 34. The Z-axis drive device 347 and the X-axis drive device 344 are connected to the X-axis slide 343. The Z-axis drive device 347 is connected to the wax spray head support 346. The wax spray head 33 is fixedly mounted on the wax spray head support 346. The wax spray head drive assembly 34 drives the wax spray head 33 to move along the X-axis and Z-axis directions. It can quickly adapt to the surface height of steel pipes of different diameters, always maintain the optimal spraying distance, and ensure the uniformity of wax spraying on steel pipes of different specifications. At the same time, the wax spray head 33 can be raised to avoid obstacles when not in operation or when changing pipes.

[0026] Both the X-axis drive device 344 and the Z-axis drive device 347 of this utility model are cylinders. The cylinders drive the wax spray head 33 to move in the X-axis and Z-axis directions, which is fast and helps to improve the wax spraying efficiency.

[0027] Both the feeding mechanism 1 and the unloading mechanism 2 of this utility model include a frame 4, several feeding roller assemblies 5 evenly arranged on the frame 4, and a drive assembly 6 arranged on the frame 4 for driving the feeding roller assemblies 5. The feeding roller assembly 5 includes feeding roller support frames 51 respectively arranged on the left and right sides of the frame 4, feeding roller drive shafts 52 rotatably connected between the feeding roller support frames 51, feeding rollers 53 fixedly arranged on the feeding roller drive shafts 52, and transmission gears 54 fixedly arranged on the feeding roller drive shafts 52. Several transmission gears 54 are connected by chain transmission. The power output end of the drive assembly 6 drives the transmission gears 54. Multiple feeding rollers 53 achieve synchronous rotation through the gears connected by the chain, ensuring that the steel pipe moves smoothly and in a straight line during the conveying process, preventing the steel pipe from deviating or getting stuck, ensuring accurate positioning and smooth unloading of the steel pipe at the wax spraying station, realizing automated and continuous feeding and unloading of steel pipes, seamlessly connecting the wax spraying process, and greatly improving the overall operation efficiency.

[0028] The drive assembly 6 of this utility model includes a feeding drive motor 61 fixedly mounted on the frame 4 and a drive gear 62 mounted on the power output end of the feeding drive motor 61. The drive gear 62 and the transmission gear 54 are connected by a chain drive. The feeding drive motor 61 is driven by the drive gear 62 and the transmission gear 54. A single motor drives all the transmission gears 54 of the feeding rollers 53 to rotate synchronously through a drive gear 62 and a chain, ensuring that the rotation speed of all the feeding rollers 53 is strictly consistent, and further ensuring the stability and synchronization of the conveying.

[0029] The feeding roller 53 of this utility model has a limiting part 531 with a gradually increasing radius extending from the middle to both ends, which effectively prevents the steel pipe from deviating left or right during the conveying process, ensures that the steel pipe enters and leaves the wax spraying station in a straight line, and ensures accurate wax spraying position and smooth material feeding.

[0030] The surface of the feeding roller 53 of this utility model is provided with a rubber coating 532. The rubber coating layer significantly increases the friction between the feeding roller 53 and the surface of the steel pipe, preventing slippage and resulting poor conveying.

[0031] Working principle: When the feeding mechanism 1 is started, the feeding drive motor 61 runs, driving the drive gear 62 at its power output end to rotate. The drive gear 62 drives the transmission gear 54 on one of the feeding rollers 53 to rotate via a chain. Since the transmission gears 54 of all the feeding rollers 53 are also connected by chain transmission, all the feeding rollers 53 rotate synchronously. The stainless steel pipe is placed on the feeding roller 53 of the feeding mechanism 1. The rubber coating 532 on the surface of the feeding roller 53 provides friction, driving the steel pipe to move smoothly and linearly towards the wax spraying mechanism 3. After the steel pipe reaches the wax spraying mechanism 3, it is located on two parallel steel pipe rotating rollers 321. The X-axis drive device 344 drives the X-axis slide 343 to move along the X-axis guide rail 342, adjusting the wax spraying head support 346 and the wax spraying head 33 on it to the starting position in the length direction of the steel pipe. Z-axis drive device 347 drives the wax spray head support 346 to move along the side of Z-axis support 345, adjusting the wax spray head 33 to a suitable height. Wax liquid is supplied to the wax spray head 33 through wax tube 331, and the wax spray head 33 begins to spray wax mist, evenly covering the circumferential surface of the steel pipe below. After the waxing is completed, the coated steel pipe is sent out by the unloading mechanism 2. At the same time or after the unloading mechanism 2 transports the waxed steel pipe away, the loading mechanism 1 can transport the next steel pipe to be waxed to the position of the steel pipe rotating component 32 of the waxing mechanism 3. The above is repeated to realize continuous automated waxing operation and significantly improve the overall work efficiency.

[0032] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
