Description

Technical Field

[0001] This utility model relates to the field of sizing machine technology, and in particular to a sizing machine with an assembly roll positioning device. Background Technology

[0002] The sizing mill takes steel pipes rolled by the Pilger mill, reheats them in a walking beam furnace, and then sizing them to obtain a high-precision external dimension. The sizing roll profile can be adjusted individually or both rolls can be adjusted simultaneously. The sizing rolls of the sizing mill are the main tools for sizing. They are supported and rotated by bearings inside the sizing roll box, ensuring the correct position of the sizing rolls in the frame.

[0003] Traditional sizing machines have some drawbacks. In actual use, when the sizing machine installs the rolls, the position of the rolls needs to be manually observed by the workers to determine the installation distance and the gap between the rolls. In addition, the limitations of manual positioning operation result in low positioning accuracy, which ultimately affects the roll installation accuracy. Utility Model Content

[0004] The main purpose of this utility model is to provide a sizing machine with an assembly roll positioning device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The positioning auxiliary mechanism includes a fixed frame fixedly connected to the upper end of the frame. A slide rail is fixedly connected to one end of the fixed frame. A slide frame is slidably connected to the outer side of the slide rail. A connecting piece is fixedly connected to one end of the slide frame. A support frame is fixedly connected to one end of the connecting piece near the upper side of the slide frame. A movable frame is movably connected to the outer side of the support frame via a rotating shaft. A control groove is provided inside the movable frame. A positioning frame is movably connected to the outer side of the movable frame via a rotating shaft. A positioning frame is fixedly connected to one end of the positioning frame. A limiting ring is movably connected to the inner side of the control groove via a rotating shaft. A threaded rod is slidably connected to the inner side of the limiting ring. A nut is threadedly connected to the outer side of the threaded rod near the limiting ring. A spring is sleeved on the outer side of the threaded rod near the limiting ring.

[0007] Preferably, a support block is movably connected to the inner side of the support frame via a pivot, and a push rod is fixedly connected to the upper end of the support frame.

[0008] Preferably, the connector is U-shaped, the nut is in contact with the limiting ring, and one end of the spring is fixedly connected to one end of the limiting ring.

[0009] Preferably, one end of the support block is fixedly connected to one end of the threaded rod, and the other end of the spring is fixedly connected to one end of the support block near the outer side of the threaded rod.

[0010] Preferably, a first roll is movably connected to the inner side of the frame via a rotating shaft, and a second roll is movably connected to the inner side of the frame near the lower side of the first roll via a rotating shaft.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a sizing machine with a roll positioning device includes a frame 1. A positioning auxiliary mechanism 5 is provided at the upper end of the frame 1. The positioning auxiliary mechanism 5 includes a fixed frame 51 fixedly connected to the upper end of the frame 1. A slide rail 52 is fixedly connected to one end of the fixed frame 51. A slide carriage 53 is slidably connected to the outer side of the slide rail 52. A connecting member 54 is fixedly connected to one end of the slide carriage 53. A support frame 55 is fixedly connected to one end of the connecting member 54 near the upper side of the slide carriage 53. A movable support frame 55 is movably connected to the outer side of the support frame 55 via a rotating shaft. The movable frame 56 has a control groove 57 inside. The outer side of the movable frame 56 is movably connected to a positioning frame 58 via a rotating shaft. One end of the positioning frame 58 is fixedly connected to a positioning frame 59. The inner side of the control groove 57 is movably connected to a limiting ring 510 via a rotating shaft. The inner side of the limiting ring 510 is slidably connected to a threaded rod 511. The outer side of the threaded rod 511 near the limiting ring 510 is threaded with a nut 512. The outer side of the threaded rod 511 near the limiting ring 510 is sleeved with a spring 513.

[0021] In this embodiment, a support block 514 is movably connected to the inner side of the support frame 55 via a rotating shaft. A push rod 515 is fixedly connected to the upper end of the support frame 55. The connecting piece 54 is U-shaped. The nut 512 is in contact with the limiting ring 510. One end of the spring 513 is fixedly connected to one end of the limiting ring 510. One end of the support block 514 is fixedly connected to one end of the threaded rod 511. The other end of the spring 513 is fixedly connected to one end of the support block 514 near the outer side of the threaded rod 511.

[0022] Specifically, by turning the nut 512 away from the limiting ring 510, the spring 513 pushes the limiting ring 510 to slide along the threaded rod 511 under its elastic force, causing the threaded rod 511 to rotate within the control groove 57. This, in turn, causes the threaded rod 511 to rotate the support block 514, thereby pushing the movable frame 56. This changes the angle between the movable frame 56 and the support frame 55. Then, the angle between the positioning frame 58 and the movable frame 56 is adjusted. Finally, the nut 512 is turned in the opposite direction to bring it into contact with... By adjusting the limiting ring 510, the included angle between the movable frame 56 and the support frame 55 can be limited, which helps to position the No. 1 roll 2, No. 2 roll 3, and No. 3 roll 4. By turning the nut 512, the spring 513 pushes the limiting ring 510, and the limiting ring 510 drives the movable frame 56, thereby adjusting the included angle between the movable frame 56 and the support frame 55. This makes it easier to position the positioning frame 59 at a distance from the specified position of the frame 1, which helps to position the No. 1 roll 2, No. 2 roll 3, and No. 3 roll 4.

[0023] In this embodiment, a first roll 2 is movably connected to the inner side of the frame 1 via a rotating shaft. A second roll 3 is movably connected to the inner side of the frame 1 near the lower side of the first roll 2 via a rotating shaft. A third roll 4 is movably connected to the inner side of the frame 1 near the second roll 3 via a rotating shaft. The first roll 2, the second roll 3, and the third roll 4 are arranged in a triangular pattern.

[0024] Specifically, roll 2, roll 3, and roll 4 are placed inside the frame 1, and push rod 515 is pushed so that slide carriage 53 along slide rail 52, thereby aligning positioning frame 59 with the markings on roll 2, roll 3, and roll 4, which helps to position roll 2, roll 3, and roll 4.

[0025] Working principle:

[0026] In use, first, tighten nut 512 to move it away from the limiting ring 510. This causes spring 513 to push the limiting ring 510 along the threaded rod 511 under its elastic force, causing the threaded rod 511 to rotate within the control groove 57 and drive the support block 514 to rotate. This, in turn, pushes the movable frame 56, changing the angle between the movable frame 56 and the support frame 55. Then, adjust the angle between the positioning frame 58 and the movable frame 56. Ideally, tighten nut 512 in the opposite direction until it contacts the limiting ring 510, thus limiting the angle between the movable frame 56 and the support frame 55. Then, rolls 2, 3, and 4... The No. 4 roll is placed inside the frame 1, and the push rod 515 is pushed, causing the slide 53 to slide along the slide rail 52. This aligns the positioning frame 59 with the markings on the No. 1 roll 2, No. 2 roll 3, and No. 3 roll 4, thus facilitating the positioning of the No. 1 roll 2, No. 2 roll 3, and No. 3 roll 4. By turning the nut 512, the spring 513 pushes the limiting ring 510, which in turn drives the movable frame 56. This adjusts the angle between the movable frame 56 and the support frame 55, making it easier to position the positioning frame 59 at the specified distance from the frame 1, thereby facilitating the positioning of the No. 1 roll 2, No. 2 roll 3, and No. 3 roll 4.
