Description

Technical fields:

[0001] This invention relates to a method for adjusting the pressing depth of a tensioning roller according to the thickness of the aluminum coil being fed into the machine. Background technology:

[0002] Aluminum coil rolling equipment is used to roll aluminum coils to achieve a certain thickness. During the rolling process, at least one aluminum coil tensioning mechanism is required to maintain tension on the aluminum coil. Different tension forces have a significant impact on the rolling quality of the aluminum coil, but how to adjust the appropriate tension force to ensure quality has always been a challenge in aluminum coil rolling. Since the tension force is the pulling force on the aluminum coil, and this pulling force cannot be measured during production, there is currently no definitive answer on what tension force is used for aluminum coils of different thicknesses.

[0003] Currently, a Chinese patent, "A Rolling Device and Rolling Method for Coil Materials," publication number CN116197268A, has been found. This rolling device includes a frame bottom roller mechanism, comprising a bottom roller and a drive assembly. The bottom roller is rotatably connected to the frame, and one end of the bottom roller is driven by the drive assembly to drive the bottom roller to rotate. A pressure roller mechanism includes a base and a pressure roller. The base is slidably fitted to the frame, and the pressure roller is positioned opposite the bottom roller, with the coil material passing through between them. The rotation of the bottom roller causes the relative movement of the pressure roller to roll the welded coil material. An adjustment mechanism, installed on the frame, is used to adjust the position of the pressure roller relative to the bottom roller to roll coil materials of different widths. However, it cannot guarantee the surface quality of the aluminum coil material during rolling.

[0004] In addition, Chinese patent CN117600227A, entitled "Rolling Device, Rolling Thickness Adjustment Method, Rolling Equipment," describes a rolling device comprising an upper roller head, a lower roller head forming a roller gap between the lower and upper roller heads, a heating component fixedly positioned at the front end of the roller gap in the material flow direction, the heating component including a heating element used to heat the material at the front end of the roller gap, and a thickness gauge positioned at the rear end of the roller gap in the material flow direction, used to detect the thickness of the heated and rolled material. A controller is connected to the thickness gauge and the heating component, respectively, and the controller is used to adjust the heating intensity of the heating element based on the thickness detected by the thickness gauge. However, it cannot adjust the tension based on the thickness of the coil (aluminum coil) detected by the thickness gauge to ensure the surface quality of the rolled material (aluminum coil). Summary of the Invention:

[0005] In view of this, the purpose of the present invention is to provide a method for adjusting the pressing depth of the tension roller according to the thickness of the aluminum coil. This method for adjusting the pressing depth of the tension roller according to the thickness of the aluminum coil is reasonably designed and is conducive to ensuring the processing quality of the aluminum coil.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The present invention relates to a method for adjusting the pressing depth of tensioning rollers based on the thickness of the infeed aluminum coil, characterized in that: it includes an aluminum coil tensioning mechanism located on the discharge side of the aluminum coil pressing equipment, the aluminum coil tensioning mechanism including two spaced lower tensioning rollers and an upper tensioning roller disposed between the two lower tensioning rollers, the aluminum coil passing through between the upper tensioning roller and the two lower tensioning rollers, a thickness gauge being provided at the infeed end of the aluminum coil tensioning mechanism, the upper tensioning roller being driven to rise and fall by a lifting drive mechanism, and the thickness gauge and the lifting drive mechanism being electrically connected to a controller;

[0008] The thickness of the aluminum coil at the inlet end is measured by a thickness gauge. The controller uses this thickness data to adjust the lifting and lowering value of the lifting drive mechanism. The specific pressing depth of the tension roller corresponding to different aluminum coil thicknesses is as follows:

[0009] Aluminum coil entry thickness H / mm Tensioning roller pressing depth (cm) H≥4.0 8 3.0≤H＜4.0 7 2.0≤H＜3.0 6 1.5≤H＜2.0 5 1.0≤H＜1.5 4 0.5≤H＜1.0 3 H＜0.5 2

[0010] Preferably, the lifting drive mechanism retracts after pressing down for 25-40 seconds.

[0011] Preferably, the above-mentioned lifting drive mechanism includes two vertically arranged guide rails on the machine body and a lifting seat slidably connected between the two guide rails. The end of the upper tension roller is connected to the lifting seat, and a lead screw is vertically threaded onto the lifting seat. The upper end of the lead screw is driven to rotate by a motor fixed on the machine body. Under the action of the motor, the lead screw rotates, driving the lifting seat and the upper tension roller thereon to move vertically up and down.

[0012] Preferably, the aluminum coil feed end is provided with a base and a slide cylinder mounted on the base. The slide cylinder has a thickness gauge fixedly connected to the slider for measuring the thickness of the rolled aluminum coil. When working, the thickness gauge is driven by the slide cylinder to move closer to or away from the rolled aluminum coil. The rear end of the base is provided with a tailstock, and a buffer spring is installed on the side of the tailstock facing the thickness gauge to buffer the vibration and impact when the thickness gauge retracts.

[0013] Preferably, the tailstock includes an angle iron block welded and fixed to the rear end of the base and a square steel section welded and mounted vertically on the angle iron block.

[0014] Preferably, the buffer spring is horizontally positioned and its end is welded and fixed to the square steel section.

[0015] Preferably, the thickness gauge is a horizontally arranged U-shape, and a laser emitter is provided on the inner wall of the slot of the U-shaped thickness gauge.

[0016] Preferably, a baffle is provided on the inner wall of the slot of the U-shaped thickness gauge, located next to the laser emitter, and the baffle is located on the side away from the buffer spring.

[0017] The working principle of the method for adjusting the pressing depth of the tension roller based on the thickness of the aluminum coil in the feed is as follows: The thickness of the aluminum coil at the inlet end is measured by a thickness gauge, and the controller controls and adjusts the lifting value of the lifting drive mechanism based on the thickness data, thereby ensuring the production quality of the aluminum coil; at the same time, the controller standardizes the pressing depth, reduces manual operation, lowers the probability of human error, standardizes operations, and ensures the stability of production.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] The present invention provides a method for adjusting the pressing depth of the tensioning roller according to the thickness of the aluminum coil material. The method includes an aluminum coil tensioning mechanism 2 located on the discharge side of the aluminum coil pressing equipment 1. The aluminum coil tensioning mechanism 2 includes two lower tensioning rollers 3 spaced apart and an upper tensioning roller 4 located between the two lower tensioning rollers. The aluminum coil material 5 passes through the upper tensioning roller 4 and the two lower tensioning rollers 3. A thickness gauge 6 is provided on the feed end of the aluminum coil tensioning mechanism 2. The upper tensioning roller 4 is driven to rise and fall by a lifting drive mechanism 7. The thickness gauge 6 and the lifting drive mechanism 7 are electrically connected to a controller 8.

[0027] The thickness of the aluminum coil at the inlet end (the inlet end of the aluminum coil tensioning mechanism 2) is measured by the thickness gauge 6. The controller 8 uses this thickness data to control and adjust the lifting and lowering value of the lifting drive mechanism 7. The specific pressing depth of the tensioning roller corresponding to different aluminum coil thicknesses is as follows:

[0028] Aluminum coil entry thickness H / mm Tensioning roller pressing depth (cm) H≥4.0 8 3.0≤H＜4.0 7 2.0≤H＜3.0 6 1.5≤H＜2.0 5 1.0≤H＜1.5 4 0.5≤H＜1.0 3 H＜0.5 2

[0029] The reference point for the pressing depth of the tension roll is the rolling line A1 (the rolling line is the line connecting the upper end of the lower tension roll 3). When the lower end of the upper tension roll 4 is flush with the rolling line, the pressing depth of the tension roll is 10cm. After the upper tension roll 4 continues to press down, the pressing depth of the tension roll is 9, 8, 7, 6, 5, 4, 3, and 2 cm respectively. Figure 6 In the diagram, A1 represents the rolling line, A2 represents the tension roll pressing depth of 8cm, A3 represents the tension roll pressing depth of 6cm, and A4 represents the tension roll pressing depth of 2cm.

[0030] To avoid damage to the drive mechanism caused by prolonged downward pressure, the lifting drive mechanism retracts after 25-40 seconds of downward pressure. That is, the upper tension roller 4 retracts after being pressed down for 25-40 seconds (meaning that the upper tension roller 4 rises 25-40 seconds after being pressed down to the designated position).

[0031] The specific lifting drive mechanism 7 includes two vertically arranged guide rails 9 on the machine body and a lifting seat 10 slidably connected between the two guide rails 9. The end of the upper tension roller 4 is connected to the lifting seat 10 (meaning that both ends of the upper tension roller 4 are connected to the two lifting seats 10 respectively). A lead screw 11 is vertically threaded on the lifting seat 10. The upper end of the lead screw 11 is driven to rotate by a motor 12 fixed on the machine body. Under the action of the motor, the lead screw rotates, driving the lifting seat 10 and the upper tension roller on it to move vertically up and down, thereby realizing the pressing of the aluminum coil by the upper tension roller 4.

[0032] In order to drive the thickness gauge 6 to extend and retract as needed (the thickness gauge 6 extends when measurement is required and retracts when not measuring), the aluminum coil feed end is provided with a base 13 mounted on the machine body and a slide cylinder 14 mounted on the base 13. The slide cylinder 14 has a slider 15 fixedly connected to the thickness gauge 6 (which can be a laser thickness gauge) for measuring the thickness of the rolled aluminum coil. When working, the thickness gauge 6 is driven by the slide cylinder to move closer to or away from the rolled aluminum coil (about to enter the aluminum coil tensioning mechanism 2). A tailstock 16 is installed at the rear end of the base 13. A buffer spring 17 is installed on the side of the tailstock 16 facing the thickness gauge to buffer the vibration and impact when the thickness gauge retracts.

[0033] When the slide cylinder drives the slider and the thickness gauge on it to retract (i.e. away from the aluminum material), the thickness gauge first contacts the buffer spring, thereby reducing shaking when retracting to the end point and preventing internal components from becoming loose or damaged.

[0034] The aforementioned tailstock 16 includes an angle iron block 18 welded and fixed to the rear end of the base and a square steel section 19 vertically welded and installed on the angle iron block; wherein the first side wall of the angle iron block 18 is vertically fixed on the rear end face of the base, the second side wall of the angle iron block 18 is horizontally set, and the square steel section 19 is vertically fixed on the second side wall of the angle iron block 18.

[0035] The aforementioned buffer spring 17 is horizontally positioned, and its end is welded and fixed to the square steel section 19.

[0036] Specifically, the thickness gauge is a horizontally arranged U-shape, and a laser emitter 20 is provided on the inner wall of the slot of the U-shaped thickness gauge (using the laser emitter 20 to measure thickness is existing technology and will not be described in detail here).

[0037] A baffle 21 is provided on the inner wall of the slot of the aforementioned U-shaped thickness gauge, next to the laser emitter 20. The baffle is located on the side away from the buffer spring. The baffle 21 can be a rectangular plate, but for ease of installation, it is preferable to use an angle iron block. One side of the angle iron block is horizontally set and fixedly connected to the inner wall of the slot of the U-shaped thickness gauge, while the other side of the angle iron block is vertically set and positioned in front of the laser emitter 20 (near the aluminum coil).

[0038] The working principle of the method for adjusting the pressing depth of the tension roller based on the thickness of the aluminum coil in the feed is as follows: The thickness of the aluminum coil at the inlet end is measured by a thickness gauge, and the controller controls and adjusts the lifting value of the lifting drive mechanism based on the thickness data, thereby ensuring the production quality of the aluminum coil; at the same time, the controller standardizes the pressing depth, reduces manual operation, lowers the probability of human error, standardizes operations, and ensures the stability of production.

[0039] The above-described preferred embodiments further illustrate the purpose, technical solutions, and advantages of the present invention. It should be understood that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
