Description

Technical Field

[0001] This utility model relates to a fully automatic pipe cutting, grinding and drilling machine, belonging to the technical field of pipe processing equipment. Background Technology

[0002] High-alumina and silicon carbide tubes possess superior properties such as high strength, high hardness, good wear resistance, high temperature resistance, corrosion resistance, good thermal and shock resistance, high thermal conductivity, and good oxidation resistance. They are mainly used in medium-frequency forging, various heat treatment electric furnaces, metallurgy, chemical industry, and non-ferrous metal smelting, and are widely used in metallurgical sintering furnaces and medium-frequency heating forging furnaces. Lengths can be customized.

[0003] To achieve the designed length, high-alumina and silicon carbide tubes require cutting at both ends, followed by grinding of the outer circumference of both ends, and then slotting. Currently, in the production of high-alumina and silicon carbide tubes, this process involves manual processing at different workstations—three workstations and six people manually processing each end. This is not only inefficient and labor-intensive, but also makes it difficult to guarantee quality and precision, resulting in a high scrap rate. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a fully automatic pipe cutting, grinding and drilling machine with high processing accuracy and high production efficiency to solve the above problems.

[0005] The fully automatic pipe cutting, grinding, and drilling machine of this utility model includes a pipe cutting mechanism, a grinding mechanism, and a drilling mechanism arranged in sequence. A pipe material conveying device is provided between the mechanisms. The pipe cutting mechanism includes saw wheels arranged on both sides. The grinding mechanism includes a support wheel and a grinding wheel that can rotate and support the pipe material. A diamond grinding wheel is provided above the support wheel and the grinding wheel. The drilling mechanism includes a retainer, and drilling grinding wheels are provided above and below the retainer.

[0006] This equipment has three stations: cutting, grinding and chamfering, and pipe drilling. The pipe material passes through the cutting station, where the saw wheels on both sides cut off both ends of the pipe material. Then it passes through the grinding and chamfering station, where rotating grinding wheels grind both ends of the pipe material while diamond grinding wheels chamfer the end faces of the pipe material. After grinding, it enters the drilling station, where holes are drilled on the ground surfaces at both ends of the pipe material.

[0007] The saw wheel, diamond grinding wheel, and drilling grinding wheel can all be raised and lowered to accommodate pipes of different diameters.

[0008] In addition, the pipe cutting mechanism, grinding mechanism and drilling mechanism can move synchronously left and right, and can process pipes of different lengths.

[0009] Specifically, the tube cutting mechanism, grinding mechanism, and drilling mechanism are mounted on a movable base, which can move left and right via a ball screw device at the bottom.

[0010] The pipe conveying device of this utility model includes a feeding bracket, an intermediate bracket, and a discharging bracket arranged in sequence. The top support surfaces of the three brackets are all inclined forward, which allows the pipe to move forward automatically along the bracket. The lower end of the three brackets is provided with a pipe limiting structure. At the junction of the feeding bracket and the intermediate bracket, and at the junction of the intermediate bracket and the discharging bracket, there are two sets of liftable slides, one in front and one behind. The top support surface of the slide is also inclined forward, and the lower end of the slide is also provided with a pipe limiting structure.

[0011] The pipe material limiting structure is a limiting baffle.

[0012] To reduce dust and dissipate heat, water spray pipes are installed at the working positions of the pipe cutting mechanism, grinding mechanism, and drilling mechanism.

[0013] The advantages of this utility model compared with the prior art are:

[0014] The fully automatic pipe cutting, grinding, and drilling machine described in this utility model has a compact structure, reasonable layout, and small footprint. It can be fully automated through PLC control, and each station's feed is equipped with a servo motor, resulting in more precise processing accuracy, high processing efficiency, and high output. It is suitable for mass production, and is simple, fast, and safe to operate. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.

[0021] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.

[0022] like Figure 1 , 2 As shown, this embodiment is achieved through the following technical solution: it includes a fixed base 25, on which a pipe cutting mechanism, a grinding mechanism and a drilling mechanism are arranged in sequence on both sides. One of the mechanisms is equipped with a movable base 29. The movable base 29 can slide left and right along the guide rail 23 through the ball screw device 26 at the bottom, thereby changing the distance between the two mechanisms and processing pipes of different lengths.

[0023] A feeding bracket 6 is provided between the pipe cutting mechanism and the grinding mechanism, an intermediate bracket 15 is provided between the grinding mechanism and the drilling mechanism, and a discharging bracket 22 is provided after the grinding mechanism. The top support surfaces of the three brackets are all inclined forward, allowing the pipe 3 to move automatically forward along the brackets. The lower ends of the three brackets are provided with pipe limiting structures. The front end of the feeding bracket 6, the junction of the feeding bracket 6 and the intermediate bracket 15, and the junction of the intermediate bracket 15 and the discharging bracket 22 are each provided with two sets of liftable slides 27, one in front and one behind. The six slides 27 are driven by the feeding cylinder 1, the cutting cylinder 2, the grinding loading cylinder 11, the grinding unloading cylinder 12, the drilling loading cylinder 13, and the drilling unloading cylinder 14, respectively. The top support surface of the slide 27 is also inclined forward, and the lower end of the slide 27 is also provided with a pipe limiting structure. In this embodiment, the pipe limiting structure is a limiting baffle 28.

[0024] The pipe cutting mechanism includes saw wheels 4 on both sides; the grinding mechanism includes a support wheel 7 and a grinding wheel 10 that can rotate and support the pipe material 3; a diamond grinding wheel 9 is provided above the support wheel 7 and the grinding wheel 10; and the drilling mechanism includes a retainer 18, with drilling grinding wheels 20 provided above and below the retainer 18. The saw wheels 4, diamond grinding wheels 9, and drilling grinding wheels 20 can be raised and lowered by lead screw mechanisms driven by the saw wheel lifting motor 5, the grinding wheel lifting motor 8, the lower drilling lifting motor 17, and the upper drilling lifting motor 19, respectively.

[0025] The working positions of the pipe cutting mechanism, grinding mechanism and drilling mechanism are all equipped with water spray pipes, which draw water from water tank 24 to reduce dust and dissipate heat.

[0026] This utility model equipment measures 6.2m in length, 2.5m in width, and 1.8m in total height, with a working height of 1.1m. It can process tubes ranging from 2.5m to 5.2m in length and 40-70mm in diameter, with a high-alumina roller processing capacity of 23 seconds per tube. It features a compact structure, rational layout, and small footprint. Simultaneous processing at both ends significantly improves the coaxial precision of high-alumina roller products. The entire frame is made of 304 stainless steel, ensuring higher precision and a longer lifespan.

[0027] This utility model equipment utilizes CNC programming, touchscreen operation, and electronic sensing devices to achieve fully automated pipe cutting, grinding, chamfering, and drilling. It is suitable for mass production, offering high precision, long service life, speed, safety, and simple operation. Working principle: The feeding cylinder 1 rises, and the pipe material 3 (high-alumina or silicon carbide pipe) slides forward from the slide table 27 at the top of the feeding cylinder 1 to the feeding bracket 6. It is then blocked by the limiting baffle 28 at the top of the cutting cylinder 2, fixing it at the pipe cutting station. The saw wheel 4 descends to cut the pipe. After cutting, the cutting cylinder 2 descends, releasing the obstruction on the pipe material 3, which continues to roll forward along the feeding bracket 6 to the end.

[0028] The grinding loading cylinder 11 rises, lifting the tube 3 to the grinding station between the support wheel 7 and the grinding rubber wheel 10. The rotating grinding rubber wheel 10 grinds both ends of the tube simultaneously, while the diamond grinding wheel 9 chamfers the end face of the tube 3. After the grinding and chamfering are completed, the grinding unloading cylinder 12 rises, lifting the tube 3 away from the grinding station. The tube 3 rolls forward a distance along the slide table 27 at the top of the grinding unloading cylinder 12. The grinding unloading cylinder 12 descends, placing the tube 3 on the intermediate bracket 15. The tube 3 continues to roll forward along the intermediate bracket 15 to the end.

[0029] The punching and feeding cylinder 13 rises, lifting the tube 3 to the punching position of the holder 18. The lower punching motor 16 rises, and the upper punching motor 21 descends, causing the punching grinding wheel 20 to contact the tube 3 and punch holes on both ends of the tube 3. After punching is completed, the punching and unloading cylinder 14 rises, lifting the tube 3 away from the holder 18. The tube 3 rolls forward a distance along the slide 27 on the top of the punching and unloading cylinder 14. The punching and unloading cylinder 14 descends, placing the tube 3 on the discharge bracket 22. Finally, the tube 3 is sent out along the discharge bracket 22.
