Description

Technical Field

[0001] This utility model relates to the field of steel rolling technology, and in particular to a laser-assisted tool for coiling on a rolling mill coiler. Background Technology

[0002] In the production process of cold-rolled silicon steel sheet and strip, the coil feeding stage of a single-stand rolling mill is crucial. The coil shape directly affects the entire rolling process; if the coil shape does not meet the requirements, it may lead to a series of problems such as deviation and poor sheet shape in subsequent rolling. Among these, the condition that the center of the coil in the width direction is close to the rolling centerline is a key factor in ensuring rolling stability and product quality.

[0003] For the cold-rolling production of silicon steel, a special material, the steel coils need to be heated to approximately 90°C before being loaded onto the machine due to process requirements. Under such high temperatures, traditional measurement methods face significant challenges. Using a measuring tape for centering poses serious safety hazards; the high temperature can easily burn operators, severely impacting worker safety and work efficiency. Furthermore, there are currently no suitable external tools on the market that can accurately and safely assist in centering steel coils under these high-temperature conditions. This not only hinders efficient production but may also lead to decreased product quality due to inaccurate centering, increasing the defect rate, thereby increasing production costs and reducing enterprise profits.

[0004] This situation urgently requires a new measurement method or tool to solve the problem of centering measurement of high-temperature steel coils. Utility Model Content

[0005] This utility model provides a laser-assisted tool for winding on a rolling mill coiler, which solves the problems of safety hazards and product quality issues associated with traditional measurement methods.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A laser-assisted tool for winding on a rolling mill coiler includes a laser optical element, a telescopic rod, an operation display component, and a hand handle. The laser optical element is connected to the upper end of the telescopic rod, and a hand handle is provided at the lower end of the telescopic rod. An operation display component is provided at the lower part of the telescopic rod, and the laser optical element is electrically connected to the operation display component.

[0008] Furthermore, the laser optical element includes a first structural frame, in which a semiconductor laser emitter, an emitting lens, a receiving lens, and a photosensitive element are assembled and installed.

[0009] Furthermore, the telescopic rod comprises two stainless steel outer rods and one stainless steel inner rod, with the lower end of the first stainless steel outer rod threadedly connected to the upper end of the stainless steel inner rod, and the lower end of the stainless steel inner rod threadedly connected to the upper end of the second stainless steel outer rod.

[0010] Furthermore, the operation display component includes a second structural frame, on which a display screen, a level bead, and control buttons are disposed, and a control circuit board is disposed within the second structural frame, and the control circuit board is connected to the display screen, the level bead, and the control buttons.

[0011] Furthermore, the sum of the lengths of the first stainless steel outer rod and the second stainless steel outer rod is equal to the length of the stainless steel inner rod.

[0012] Furthermore, the hand handle is made of rubber.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model's auxiliary tool allows for direct inspection of whether the steel coil is centered after being loaded onto the machine, assisting in coil centering. The tool is simple to manufacture and has no complex structure. Its infrared ranging device has no technological barriers, and its measurement accuracy is within 1mm.

[0015] A laser-assisted tool for winding on a rolling mill coiler can meet multiple needs and optimize complex tools in actual production operations.

[0016] The infrared ranging device on the multi-functional folding ruler is used to compile measurement data so that the measured value directly corresponds to the width of the steel coil, accurately controlling the winding position and avoiding strip breakage caused by misalignment during winding, as well as burns caused by high positions.
