Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe processing equipment technology, and more specifically, to a milling head device for steel pipe processing. Background Technology
[0002] During the processing of steel pipes, steel coils need to be extruded into circular pipes using various forming molds. Then, the steel pipes are cut through processes such as welding and cutting. Since there are burrs at both ends of the steel pipe after cutting, the ends of the steel pipe need to be machined by turning.
[0003] In existing technology, the two ends of the steel pipe are generally milled by a milling machine. During milling, the steel pipe needs to be moved to the milling machine by a moving device. When moving, the steel pipe often needs to be lifted upwards first, then moved laterally, and then lowered down. The process is cumbersome and affects work efficiency. Utility Model Content
[0004] The purpose of this invention is to solve the problem of slow movement of steel pipes during milling, which affects work efficiency, and to design a milling head device for steel pipe processing.
[0005] To achieve the above objectives, the technical solution of this utility model is a milling head device for steel pipe processing, comprising two milling machines. The processing end of each milling machine is extendable. A hydraulic clamp is installed on each milling machine, and the hydraulic clamp can move up and down. A worktable is installed on the ground between the two milling machines. A rotating frame is installed on the worktable, which can hold the cut steel pipe and move the steel pipe to the position between the milling machines. Multiple feeding rollers are installed on one side of the upper end of the worktable, and multiple unloading rollers are installed on the other side of the upper end of the worktable. A positioning frame is installed on each milling machine, which can position the steel pipe.
[0006] Furthermore, the rotating frame includes a rotating shaft located above the worktable, on which multiple rolling bearings are mounted. The rolling bearings are mounted on the worktable via support rods. A fixed platform is mounted on one side of the upper end of the worktable, and a servo motor is mounted on the fixed platform. The rotating end of the servo motor is connected to the rotating shaft. Multiple holding rods are mounted on the rotating shaft, and a limit ring is mounted on one end of each holding rod, allowing the steel pipe to enter the limit ring.
[0007] Furthermore, the positioning frame includes a first electric telescopic rod located on both sides of the rotating shaft. The lower end of the first electric telescopic rod is mounted on the milling machine, and a second electric telescopic rod is mounted on the upper end of the first electric telescopic rod. A positioning plate is mounted on the telescopic end of the second electric telescopic rod.
[0008] Furthermore, ratchet wheels are installed at both ends of the rotating shaft, and a pawl is connected to one end of each ratchet wheel. The pawl is mounted on a support rod.
[0009] Furthermore, the feeding roller and the unloading roller are provided with arc-shaped grooves.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0017] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0018] This utility model provides, for example Figure 1-4 The milling head device for steel pipe processing shown includes two milling machines 1. The processing end of the milling machine 1 is telescopic. A hydraulic clamp 2 is installed on the milling machine 1. The hydraulic clamp 2 can move up and down. A worktable 3 is installed on the ground between the two milling machines 1. A rotating frame 4 is installed on the worktable 3. The rotating frame 4 can hold the cut steel pipe and can move the steel pipe to the position between the milling machines 1. Multiple feeding rollers 5 are installed on one side of the upper end of the worktable 3, and multiple unloading rollers 6 are installed on the other side of the upper end of the worktable 3. A positioning frame 7 is installed on the milling machine 1. The positioning frame 7 can position the steel pipe.
[0019] The process of milling steel pipes using this device is as follows: The forming and cutting devices allow the steel pipe to move and be cut. During the movement of the steel pipe, the feeding roller 5 supports the steel pipe and allows it to enter the rotating frame 4. After the steel pipe is cut, the rotating frame 4 moves the steel pipe to a position between the two milling machines 1, and the feeding roller 5 picks up a new steel pipe. The positioning frame 7 positions the steel pipe, and the hydraulic clamp 2 holds the steel pipe to prevent it from shaking. The milling machine 1 is started, and the milling machine 1 can mill both ends of the steel pipe by rotating and extending its processing end. After milling, the milling machine returns to its original position, and after the next steel pipe is cut, the rotating frame 4 is started to rotate again. The rotating frame 4 can move the milled steel pipe to the unloading roller 6. The rotation of the unloading roller 6 can unload the steel pipe, and the cut steel pipe is moved between the two milling machines 1 for easy processing.
[0020] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 4The rotating frame 4 includes a rotating shaft 8 located above the worktable 3. Multiple rolling bearings 9 are installed on the rotating shaft 8. The rolling bearings 9 are installed on the worktable 3 via support rods 10. A fixed platform 11 is installed on one side of the upper end of the worktable 3. A servo motor 12 is installed on the fixed platform 11. The rotating end of the servo motor 12 is connected to the rotating shaft 8. Multiple holding rods 13 are installed on the rotating shaft 8. A limit ring 14 is installed at one end of the holding rod 13. The steel pipe can enter the limit ring 14.
[0021] The process of rotating the steel pipe driven by the rotating frame 4 is as follows: Under normal conditions, a set of limiting rings 14 are located on one side of the feeding roller 5. When the steel pipe is fed, the lower end of the steel pipe can fall on the feeding roller 5. The feeding roller 5 can support the steel pipe, which makes it easier for the steel pipe to enter the limiting ring 14. After the steel pipe is cut, the servo motor 12 is started to rotate. The servo motor 12 can drive the rotating shaft 8 to rotate. The rotating shaft 8 can drive the steel pipe to rotate through the holding rod 13 and the limiting ring 14. After the steel pipe is milled, the rotating shaft 8 rotates again, which can move the steel pipe to the upper end of the unloading roller 6. Then the unloading roller 6 can unload the steel pipe.
[0022] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 The positioning frame 7 includes a first electric telescopic rod 15 located on both sides of the rotating shaft 8. The lower end of the first electric telescopic rod 15 is mounted on the milling machine 1, and a second electric telescopic rod 16 is mounted on the upper end of the first electric telescopic rod 15. A positioning plate 17 is mounted on the telescopic end of the second electric telescopic rod 16.
[0023] The positioning frame 7 positions the steel pipe as follows: After the steel pipe rotates between the two milling machines 1, the first electric telescopic rod 15 is extended, which allows the second electric telescopic rod 16 and the positioning plate 17 to move upward, thereby allowing the positioning plate 17 to move to one side of the steel pipe. Then, the second electric telescopic rod 16 is extended, which can drive the positioning plate 17 to move laterally, thereby pushing and positioning the steel pipe. After positioning, the steel pipe is clamped by the hydraulic clamp 2. Then, the first electric telescopic rod 15 and the second electric telescopic rod 16 are shortened, which allows the positioning plate 17 to return to its original position and avoid the processing end of the milling machine 1.
[0024] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The rotating shaft 8 is equipped with ratchet wheels 18 at both ends, and a pawl 19 is connected to one end of the ratchet wheel 18. The pawl 19 is mounted on the support rod 10. When the servo motor 12 drives the rotating shaft 8 to rotate, the ratchet wheel 18 can rotate. The pawl 19 will not obstruct the rotation of the rotating shaft 8 and the ratchet wheel 18. When the servo motor 12 is turned off, the pawl 19 can limit the ratchet wheel 18 and prevent the rotating shaft 8 from reversing.
[0025] Refer to the instruction manual appendix Figure 4The feeding roller 5 and the unloading roller 6 have arc-shaped grooves 20, which can limit the movement of the steel pipe and prevent it from shaking.
[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
