[0002] Steel pipe forming equipment uses multiple sets of extrusion rollers to sequentially extrude strip steel, shaping its cross-section into a specific form. The strip sections are then joined using a welding method to produce a product that meets standards. During installation, commissioning, and specification changes, the positions of the extrusion rollers in a steel pipe forming production line need to be adjusted to ensure all rollers are in their designated positions. The position of the extrusion rollers directly determines the quality of the formed steel pipe; therefore, high-precision adjustment and repeated positioning of the extrusion rollers directly determine the quality and grade of the products produced by the steel pipe forming equipment.

[0003] Currently, the adjustment of the extrusion rollers is generally driven by an electric motor or manually, requiring manual verification of the roller's position or distance. However, this method demands a high level of skill and experience from the adjuster, and is labor-intensive, inaccurate, inefficient, and time-consuming. Furthermore, it cannot achieve repeatable positioning, collect production technical parameters of the steel pipe forming equipment, diagnose equipment malfunctions, or provide adjustment suggestions, resulting in poor adaptability and practicality.

[0033] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] Please refer to the following: Figures 1 to 4 The present invention will now describe the extrusion roller precision measuring device. The extrusion roller precision measuring device includes a protective housing 10, a distance measuring mechanism 20, and a matching controller.

[0035] The protective housing 10 is fixed on the steel pipe forming equipment, and the protective housing 10 has a bearing cavity.

[0036] The ranging mechanism 20 is disposed in the bearing cavity. The ranging mechanism 20 has a horizontally disposed feedback part that slides horizontally. The feedback part can extend outward through the side wall of the protective housing 10 and abut against the bearing seat of the extrusion roller to be adjusted, for measuring the displacement of the extrusion roller.

[0037] The matching controller is electrically connected to the ranging mechanism 20 and is used to record the movement data of the feedback unit.

[0038] The extrusion roller precision measuring device provided in this embodiment, compared with the prior art, features a protective housing 10. A ranging mechanism 20 can be installed inside the protective housing 10. The ranging mechanism 20 extends outward through the side wall of the protective housing 10 via a horizontally sliding feedback section and abuts against the bearing seat of the extrusion roller to be adjusted, thereby measuring the displacement of the extrusion roller. A matching controller can be electrically connected to the ranging mechanism 20 and can record the movement data of the feedback section.

[0039] In some embodiments, the ranging mechanism 20 package described above can be adopted as follows: Figure 2 , Figure 4 The structure shown. See also Figure 2 , Figure 4 The direction in which the feedback unit extends is defined as the first direction, and the direction that is perpendicular to and horizontal to the first direction is defined as the second direction.

[0040] The ranging mechanism 20 includes a slide rail 21, a slider 22, a feedback rod 23, and a magnetic scale 24. The slide rail 21 is fixed within the protective housing 10 and is arranged along a first direction. The slider 22 is slidably mounted on the slide rail 21 along the first direction. The feedback rod 23 is fixed on the slider 22 and moves with the slider 22; the feedback rod 23 serves as the feedback mechanism. The magnetic scale 24 is disposed within the bearing cavity and has a sliding portion connected to the slider 22. The sliding portion slides along the first direction with the slider 22 and is used to measure the displacement of the feedback rod 23.

[0041] The protective housing 10 has an extension hole on its side wall for the feedback rod 23 to extend out.

[0042] The slide rail 21 can be fixedly mounted within the protective housing 10 along the first direction. The slider 22 can be slidably mounted on the slide rail 21 along the first direction. The feedback rod 23 can be fixed on the slider 22 and can move with the slider 22. The magnetic scale 24 can measure the displacement of the feedback rod 23.

The sliding part is the magnetic head 242.

[0044] The magnetic strip 241 can be fixed on the slide rail 21. The magnetic head 242 can be slidably disposed above the magnetic strip 241 along a first direction. The displacement of the magnetic head 242 on the magnetic strip 241 can be converted into an electrical signal.

[0045] The magnetic scale 24 is a sensor that uses electromagnetic properties and magnetic recording principle to measure displacement. The magnetic scale 24 reads the magnetization signal on the magnetic scale through the magnetic head 242 and converts the displacement into an electrical signal output, thereby realizing accurate position measurement. When the magnetic head 242 moves relative to the magnetic scale, the coil in the magnetic head 242 will induce an electrical signal corresponding to the change in the magnetic signal. After being processed by the detection circuit, these electrical signals can be converted into standard signals that can be used by subsequent equipment, such as digital signals or analog signals.

[0046] In some embodiments, the slide rail 21 may be adopted as follows: Figure 1 , Figure 2 , Figure 4 The structure shown. See also Figure 1 , Figure 2 , Figure 4 The slide rail 21 is equipped with multiple limit switches 211, which are spaced apart in the bearing cavity and used to measure the zero point and limit of the magnetic head 242.

[0047] Limit switch 211 can measure the zero point and limit of magnetic head 242.

[0048] Limit switch 211 is an electrical component used to detect and control the position of mechanical movement. Limit switch 211, also known as limit switch or position switch, is a commonly used low-current master control electrical appliance, mainly used to switch circuits according to the position changes of moving parts. Limit switch 211 is existing technology and will not be described in detail here.

One end of the reset spring is connected to the slider 22, and the other end of the reset spring is connected to the inner wall of the protective housing 10. The reset spring is used to ensure that the feedback rod 23 always tends to move outward from the bearing cavity.

[0050] The reset spring can make the feedback rod 23 always tend to move outward from the bearing cavity.

See also Figure 2 , Figure 4 The extrusion roller precision measuring device also includes an electrical connection structure 30, which is connected to the magnetic head 242 and the matching controller. The electrical connection structure 30 is a drag chain.

[0052] A cable chain is a device used to protect and pull cables, oil pipes, air pipes, etc. It consists of multiple unit links that can rotate freely, allowing the cable chain to move with the mechanical equipment without damaging the internal pipelines.

[0053] In some embodiments, the protective housing 10 may be adopted as follows: Figures 1 to 4 The structure shown. See also Figures 1 to 4 The protective housing 10 includes a housing body 11 and a cover plate 12. The top of the housing body 11 is open.
