Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a fully automatic pipe cutting and grinding machine that integrates pipe cutting and grinding functions. Background Technology

[0002] Special ceramic tubes such as high-alumina tubes and silicon carbide tubes are widely used in metallurgical, chemical, and heat treatment industries due to their excellent properties such as high strength, high hardness, high temperature resistance, and corrosion resistance. During the production process, these tubes require fixed-length cutting, end face grinding and chamfering, and grooving or drilling near the ends according to design requirements.

[0003] Currently, these processing steps are typically completed by workers on different independent machines. For example, a tube needs to be cut at both ends on a cutting machine, and then transferred to a grinding machine for grinding the outer circumference and chamfering of both ends. This multi-station, segmented processing mode not only requires operators for each station, resulting in high labor costs and high labor intensity, but also easily generates cumulative errors during the multiple transfers and repeated positioning of the tube, affecting the coaxiality and dimensional accuracy of the product, thus leading to a high scrap rate and making it difficult to meet the needs of large-scale production. Utility Model Content

[0004] The main purpose of this utility model is to overcome the shortcomings of the existing technology and provide a fully automatic tube cutting and grinding machine with a compact structure, high degree of automation, excellent processing accuracy and production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic pipe cutting and grinding integrated machine, comprising a frame, a pipe cutting mechanism and a grinding mechanism arranged sequentially along the length of the frame, and a pipe material conveying device disposed between the mechanisms. Each processing mechanism is symmetrically arranged on both sides of the pipe material to be processed. The pipe cutting mechanism includes pipe cutting saw wheels symmetrically arranged on both sides; the grinding mechanism includes a support wheel and a rotation drive wheel for supporting and driving the rotation of the pipe material, and an end-face chamfering grinding wheel located above the pipe material. Both the pipe cutting saw wheel and the end-face chamfering grinding wheel are equipped with independent lifting drive mechanisms to adapt to pipe materials of different specifications and perform processing actions.

[0006] In a preferred embodiment of this invention, the equipment may also integrate a drilling mechanism after the grinding mechanism to achieve one-stop fully automated processing of pipe cutting, grinding, and drilling. The drilling mechanism may include a V-shaped support frame for fixing the pipe material and drilling grinding heads located on its upper and lower sides.

[0007] As a further preferred technical solution, one of the processing mechanisms can move horizontally synchronously to flexibly adjust the processing distance between the two mechanisms, thus adapting to the processing of pipes of different lengths. Specifically, the processing mechanisms on one side can be mounted together on a movable base, which is driven by a ball screw device to achieve precise horizontal movement and positioning.

[0008] To achieve automated pipe material conveying, the pipe material conveying device may include sequentially arranged feeding brackets and intermediate brackets, with the bearing surfaces of all brackets inclined forward. Between adjacent brackets and at the feeding end, there are liftable conveying platforms, whose bearing surfaces are also inclined, and through pipe material limiting structures such as baffles on them, orderly conveying between workstations is achieved.

[0009] In addition, water spray pipes can be installed in the working areas of each processing unit to effectively cool down and remove dust during the processing.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. High integration and space saving: Multiple processes such as pipe cutting and grinding are integrated into one machine, which has a compact structure and reasonable layout, greatly reducing the machine's footprint.

[0011] 2. Fully automated and highly efficient: Controlled by a PLC system, the entire process from material loading and station switching to processing and unloading is fully automated. Both ends can process simultaneously, resulting in high production efficiency and making it suitable for mass production.

[0012] 3. Precise control and quality assurance: Each processing action is driven by precision components such as servo motors, ensuring precise positioning and effectively guaranteeing the dimensional accuracy and coaxiality of the product, thus reducing the scrap rate.

[0013] 4. Convenient and safe operation: The automated process reduces manual intervention, lowers the labor intensity and safety risks for operators, and is simple and quick to operate. Attached Figure Description

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] The description of this utility model is merely a structural or even functional description of the embodiments, and the scope of this utility model is not limited by the embodiments described herein.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description will be provided in conjunction with the appendix. Figures 1 to 5 A preferred embodiment of the present invention will be described in detail. This embodiment demonstrates a complete device integrating three workstations: pipe cutting, grinding, and drilling.

[0019] The equipment in this embodiment mainly includes a fixed base 25 and a movable base 29, which together constitute the equipment frame. Three sets of processing mechanisms are symmetrically mounted on the frame: a pipe cutting mechanism, a grinding mechanism, and a drilling mechanism. The processing mechanisms mounted on the movable base 29 can move horizontally left and right along the guide rail 23 via the ball screw device 26 at their bottom, thereby precisely adjusting the distance between the two processing mechanisms to accommodate the processing requirements of pipes 3 of different lengths.

[0020] The pipe conveying device runs through the entire equipment. 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 discharge bracket 22 is provided after the drilling mechanism. The top bearing surfaces of these three brackets are all inclined forward, so that the pipe 3 can roll forward automatically on them by gravity.

[0021] To ensure the orderly transfer of the pipe material 3 between various workstations, lifting conveyor platforms 27, driven by cylinders, are installed at the beginning of the feeding tray 6, at the junction of the feeding tray 6 and the intermediate tray 15, and at the junction of the intermediate tray 15 and the discharge tray 22. These lifting conveyor platforms 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 bearing surface of each lifting conveyor platform 27 is also inclined forward, and its lower end is equipped with a baffle plate 28 for controlling the movement of the pipe material 3.

[0022] The specific composition of each processing mechanism is as follows: Pipe cutting mechanism: mainly includes pipe cutting saw wheels 4 located on both sides of the pipe 3, whose lifting and lowering are controlled by a screw mechanism driven by a pipe cutting lifting motor 5.

[0023] Grinding mechanism: mainly includes a support wheel 7 for supporting the tube 3 and a rotary drive wheel 10 for driving the tube 3 to rotate. Above the tube 3, there is an end face chamfering grinding wheel 9 for chamfering the end face, and its lifting is driven by a chamfering grinding wheel lifting motor 8.

[0024] The drilling mechanism mainly includes a V-shaped support frame 18 for stabilizing and fixing the tube material 3 during processing, and drilling grinding heads 20 located on the upper and lower sides of the V-shaped support frame 18, respectively. The rotation of the upper and lower drilling grinding heads 20 is driven by the upper drilling motor 21 and the lower drilling motor 16, respectively, and their lifting is controlled by the upper grinding head lifting motor 19 and the lower grinding head lifting motor 17, respectively.

[0025] To cool down and remove dust during processing, all processing stations are equipped with water spray pipes, with the water source coming from the water tank 24 at the bottom of the equipment.

[0026] Work process: The complete workflow of this embodiment includes three stages: pipe cutting, grinding, and drilling.

[0027] 1. Loading and pipe cutting process Initially, the pipe material 3 to be processed is placed on the feeding tray 6, and its forward rolling is blocked by the baffle plate 28 on the lifting conveyor 27 controlled by the feeding cylinder 1. At the start of the processing cycle, the feeding cylinder 1 descends, causing the corresponding lifting conveyor 27 to descend synchronously, releasing the obstruction on the pipe material 3. The pipe material 3 then rolls forward along the inclined feeding tray 6 until it is stopped by the baffle plate 28 on the lifting conveyor 27 controlled by the cutting cylinder 2. At this point, the pipe material 3 is precisely positioned at the pipe cutting station. Subsequently, the pipe cutting saw wheels 4 on both sides descend under the drive of the pipe cutting lifting motor 5, simultaneously cutting both ends of the pipe material 3. After cutting, the cutting cylinder 2 descends, releasing the obstruction on the pipe material 3, allowing it to continue rolling forward along the feeding tray 6 to the end of the tray.

[0028] 2. Grinding and chamfering process When the tube 3 reaches the end of the feeding bracket 6, the grinding loading cylinder 11 drives its corresponding lifting conveyor 27 to rise, smoothly lifting the tube 3 from the bracket. The tube 3 rolls along the inclined surface of the lifting conveyor 27 to its front end, located above the support wheel 7 and the rotary drive wheel 10 of the grinding station. Then, the grinding loading cylinder 11 descends, and the tube 3 is smoothly placed on the support wheel 7 and the rotary drive wheel 10. At the grinding station, the rotary drive wheel 10 drives the tube 3 to rotate, while the upper end-face chamfering grinding wheel 9 descends under the drive of the chamfering grinding wheel lifting motor 8, grinding and chamfering both ends of the rotating tube 3. After this process is completed, the grinding unloading cylinder 12 rises, and the lifting conveyor 27 at its top lifts the tube 3 from the grinding station, and the tube 3 rolls forward a short distance along the lifting platform. Subsequently, the grinding unloading cylinder 12 descends, placing the tube 3 on the intermediate bracket 15, and the tube 3 continues to roll forward along the bracket to the end.

[0029] 3. Drilling process After the tube 3 reaches the end of the intermediate support 15, the punching and feeding cylinder 13 drives its corresponding lifting conveyor 27 to rise, lifting the tube 3 and sending it into the V-shaped support frame 18 of the punching station. After the tube 3 is stabilized in the V-shaped support frame 18, the upper grinding head lifting motor 19 and the lower grinding head lifting motor 17 drive the upper and lower punching grinding heads 20 to move toward the tube 3, respectively. The punching grinding heads 20, driven to rotate by the upper punching motor 21 and the lower punching motor 16, contact the surface of the tube 3 and punch holes (grooving) at designated positions at both ends.

[0030] 4. Discharge process After drilling is completed, the upper and lower drilling heads 20 are reset. The drilling and unloading cylinder 14 rises, lifting the processed tube 3 from the V-shaped support frame 18. After the tube 3 rolls forward a distance along the lifting conveyor table 27, the drilling and unloading cylinder 14 descends, unloading the finished tube 3 (e.g., ...) Figure 5 As shown in the diagram, the tube 3 is placed on the discharge tray 22. Finally, the tube 3 is sent out of the equipment along the discharge tray 22, and the entire automated processing flow ends.

[0031] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
