Description

Technical Field

[0001] This utility model relates to the field of cold rolling technology for sheet metal, and in particular to a sheet metal guiding device for cold rolling. Background Technology

[0002] In the production process of cold-rolled steel sheets, the guiding and positioning of the sheets is a crucial step. Cold-rolled steel sheets typically have high strength and good surface quality, but due to differences in their size and shape, as well as various deviations that may occur during production, the sheets are prone to offset and skewing during transportation and processing. This not only affects the quality and precision of the product, but may also lead to damage to the production equipment.

[0003] Traditional sheet metal guiding devices mostly use fixed guiding structures, which are difficult to adapt to sheets of different sizes and shapes, and cannot effectively fine-tune the sheets. When the sheet metal deviates during the conveying process, traditional guiding devices often cannot correct it in a timely and accurate manner, leading to errors in subsequent processing of the sheet metal. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems existing in the current cold-rolled sheet metal guiding device, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a guide device for cold-rolled sheet metal, which addresses the problem that traditional sheet metal guide devices mostly use fixed guide structures, making it difficult to adapt to sheet metal of different sizes and shapes, and also unable to effectively fine-tune the sheet metal. When the sheet metal deviates during the conveying process, traditional guide devices often cannot correct it in a timely and accurate manner, leading to errors in subsequent processing of the sheet metal.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a guide device for cold-rolled sheet metal, comprising:

[0008] A guide unit includes a support body, on which a worktable is provided, and a groove is formed on the worktable;

[0009] The fine-tuning unit includes symmetrically arranged sliders located inside a slide groove. A mounting plate is fixedly installed on the slider. A bracket is fixedly connected to one side of the two mounting plates that are close to each other. A connecting rod is rotatably connected to the bracket. Contact wheels are movably installed at both ends of the connecting rod. A trigger switch is installed on the side of the mounting plate near the connecting rod.

[0010] In a preferred embodiment of the cold-rolled sheet metal guiding device of this utility model, the fine-tuning unit further includes a mounting box, which is fixedly installed on the bottom of the workbench. A connecting shaft is provided inside the mounting box, the bottom end of which passes through the mounting box and extends to the bottom of the mounting box. A synchronizing rod is fixedly connected to the bottom end of the connecting shaft, and both ends of the synchronizing rod are rotatably connected to pull rods. The synchronizing rod and the slider are rotatably connected through the pull rods.

[0011] In a preferred embodiment of the cold-rolled sheet metal guiding device of this utility model, a spring is installed inside the mounting box, one end of the spring is connected to the connecting shaft, and the spring has a preload force that enables the connecting shaft to rotate circumferentially.

[0012] As a preferred embodiment of the cold-rolled sheet metal guiding device of this utility model, the guiding unit further includes a gantry frame, which is fixedly installed on the support body. A rotary motor is fixedly installed on the gantry frame, and two rotary motors are symmetrically arranged. A rotating shaft passes through the gantry frame, and the bottom end of the rotating shaft is rotatably connected to the support body. A universal coupling is used to drive the output end of the rotary motor and the rotating shaft. The control circuit of the rotary motor is connected to a trigger switch signal.

[0013] As a preferred embodiment of the cold-rolled sheet metal guiding device of this utility model, the rotating shaft is provided with a guide wheel, and the guide wheel is provided with a plurality of limiting grooves, the diameter of the limiting grooves decreasing from top to bottom.

[0014] In a preferred embodiment of the cold-rolled sheet metal guiding device of this utility model, a hydraulic rod is fixedly installed on the supporting body, the output direction of the hydraulic rod is upward, and the output end of the hydraulic rod is fixedly connected to the worktable.

[0015] The beneficial effects of this utility model are as follows: By setting a fine-tuning unit, when the trigger switch is triggered, a signal is sent to the control circuit of the rotary motor on the same side as the triggered trigger switch. The control rotary motor on one side starts, and the rotary motor drives the rotating shaft to rotate through the universal coupling, which in turn drives the guide wheel to rotate. This increases the conveying speed of the plate on one side, thereby straightening the plate and realizing automatic guidance and adjustment of the plate, which improves production efficiency.

[0026] Example

[0027] Reference Figures 1-4 This invention provides a guide device for cold-rolled sheet metal, comprising a guide unit 100 and a fine-tuning unit 200. The guide unit 100 includes a support body 101, on which a worktable 102 is mounted, and a groove 103 is formed on the worktable 102. The fine-tuning unit 200 includes symmetrically arranged sliders 201 located inside the groove 103. Mounting plates 202 are fixedly mounted on the sliders 201. A bracket 211 is fixedly connected to one side of the two mounting plates 202 that are close to each other. A connecting rod 203 is rotatably connected to the bracket 211. Contact wheels 204 are movably mounted at both ends of the connecting rod 203, and the contact wheels 204 are used to contact the sheet metal. A trigger switch 205 is mounted on the side of the mounting plate 202 near the connecting rod 203. When the sheet metal contacts the contact wheel 204 and pushes it to move, the trigger switch 205 is triggered.

[0028] The fine-tuning unit 200 also includes a mounting box 206, which is fixedly mounted on the bottom of the worktable 102. A connecting shaft 207 is disposed inside the mounting box 206. The bottom end of the connecting shaft 207 passes through the mounting box 206 and extends to the bottom of the mounting box 206. A synchronizing rod 208 is fixedly connected to the bottom end of the connecting shaft 207. Both ends of the synchronizing rod 208 are rotatably connected to pull rods 209. The synchronizing rod 208 and the slider 201 are rotatably connected via the pull rods 209. When the slider 201 moves within the slide groove 103, it drives the synchronizing rod 208 and the connecting shaft 207 to rotate via the pull rods 209. A spring 210 is installed inside the mounting box 206. One end of the spring 210 is connected to the connecting shaft 207. The spring 210 has a preload force capable of causing the connecting shaft 207 to rotate circumferentially, which is used to reset the slider 201 after it moves by the rebound force of the spring 210.

[0029] The guide unit 100 also includes a gantry frame 104, which is fixedly mounted on the support body 101. A rotary motor 105 is fixedly mounted on the gantry frame 104. Two rotary motors 105 are symmetrically arranged. A rotating shaft 106 passes through the gantry frame 104, and the bottom end of the rotating shaft 106 is rotatably connected to the support body 101. A universal coupling 107 is used for transmission between the output end of the rotary motor 105 and the rotating shaft 106. When the trigger switch 205 is triggered, a signal is sent to the control circuit of the rotary motor 105 to start the rotary motor 105, which then drives the rotating shaft 106 to rotate via the universal coupling 107. A guide wheel 108 is provided on the rotating shaft 106, and several limiting grooves 109 are formed on the guide wheel 108. The diameter of the limiting grooves 109 decreases from top to bottom, used for further guiding and limiting the material.

[0030] A hydraulic rod 110 is fixedly installed on the support body 101. The output direction of the hydraulic rod 110 is upward, and the output end of the hydraulic rod 110 is fixedly connected to the worktable 102. By adjusting the extension length of the hydraulic rod 110, the height of the worktable 102 can be adjusted to accommodate plates of different thicknesses.

[0031] During use, in the production of cold-rolled sheet metal, when the sheet metal enters the guiding device, it first contacts the contact wheel 204. Due to possible differences in the size and shape of the sheet metal, the contact wheel 204 moves along the slide groove 103 under the push of the sheet metal, and drives the synchronizing rod 208 and the connecting shaft 207 to rotate via the pull rod 209. At this time, the spring 210 is stretched and stores energy, and then passes between the two guide wheels 108, which guide and limit the sheet metal.

[0032] When the entire board tilts rather than shifts, the guide wheel 108 becomes inactive, causing the connecting rod 203 to change angle. When the trigger switch 205 is activated, a signal is sent to the control circuit of the rotary motor 105 on the same side as the activated switch 205, starting the rotary motor 105 on that side. The rotary motor 105 drives the shaft 106 to rotate via the universal coupling 107, which in turn drives the guide wheel 108 to rotate, thus increasing the conveying speed of the board on one side and straightening the board.

[0033] The limiting groove 109 on the guide wheel 108 further guides and limits the sheet material, ensuring its stability and accuracy during conveying and processing.

[0034] When the plate passes the contact wheel 204, the spring force of the spring 210 will reset the slider 201 and the contact wheel 204, preparing for the next fine adjustment.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
