Description

Technical Field

[0001] This utility model relates to the technical field of roll testing, and in particular to a device for testing the hardness of alloy steel rolls. Background Technology

[0002] The rolling mill is the main working component and tool that causes continuous plastic deformation of metal. Rolls are mainly composed of three parts: the roll body, the roll neck, and the shaft end. The roll body is the middle part of the roll that actually participates in rolling the metal; it has a smooth cylindrical or grooved surface. The roll neck is installed in a bearing and transmits the rolling force to the stand through the bearing housing and pressing device. The shaft end is connected to the gear housing via a connecting shaft, transmitting the torque of the motor to the roll. Hardness is the ability of a material to resist indentation by a harder object. During roll production, to ensure that the produced rolls meet the hardness requirements, hardness testing of the cast steel parts is necessary. Although many portable hardness testers are available, facilitating hardness testing, in the actual production process of rolls, considering the actual working environment and the operability of portable testers, the initial hardness testing of rolls on existing production lines still mainly relies on Vickers hardness testing or Rockwell hardness testing. This primarily depends on a diamond with a fixed apex angle being pressed into the surface of the material under a certain load, and the hardness of the material is determined by the indentation and depth.

[0003] The existing Chinese utility model patent with application number CN201921909360.8 relates to a roll hardness detection device, which includes a support frame, an infrared rangefinder, a clamping rod, a linear motor, a threaded rod, a hydraulic rod, and a horizontal sensor. It can calculate the depth of the indentation captured by a microscopic camera, thereby obtaining the hardness. It is easy to use and operate.

[0004] However, the above-mentioned device does not have the ability to quickly fix the steel roll in actual use. When fixing the clamp, the level of the steel roll needs to be adjusted to ensure the accuracy of the test data. In addition, dirt adhering to the surface of the steel roll will affect the test data. The above-mentioned device does not have the ability to clean the surface of the steel roll, which increases the labor intensity of the operators. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an alloy steel roll hardness testing device that uses a fixing device to horizontally support and fix the spatial position of the steel roll, while simultaneously loosening the edge of the steel roll to adjust the side detection area of ​​the steel roll, using a cleaning device to assist in cleaning the surface of the steel roll to reduce the influence of debris on the detection data, and using a transverse movement device to detect different horizontal positions on the steel roll, thereby improving the practicality of the device.

[0006] This utility model discloses a hardness testing device for alloy steel rolls. It includes a fixing device, a cleaning device, and a transverse movement device. The cleaning device and the transverse movement device are both mounted on the fixing device. The fixing device provides horizontal support and spatial fixation for the steel roll, while simultaneously loosening the edge of the steel roll to adjust the side testing area. The cleaning device assists in cleaning the surface of the steel roll, reducing the impact of surface debris on the testing data. The transverse movement device detects different horizontal positions on the steel roll, improving the device's practicality.

[0007] Preferably, the fixing device includes a frame, a first electric cylinder, a support frame, a second electric cylinder, and an arc-shaped pressure plate. A set of first electric cylinders is horizontally installed on each of the left and right sides of the frame. The moving end of the first electric cylinder extends through the outer side of the frame into the frame and connects to the support frame. A bearing groove is provided on the inner side of the support frame. A second electric cylinder is installed on the upper end of the support frame. The moving end of the second electric cylinder extends through the upper end of the support frame into the bearing groove of the support frame. An arc-shaped pressure plate is connected to the moving end of the second electric cylinder. By controlling the extension of the two sets of first electric cylinders, the position between the two sets of support frames is adjusted, enabling the equipment to provide support and position fixing for steel rolls of different lengths. The two ends of the steel roll are respectively placed into the bearing grooves of the two sets of support frames. By controlling the extension of the second electric cylinder, the arc-shaped pressure plate on the moving end of the second electric cylinder fixes the steel roll, preventing the vibration or rotation of the steel roll itself from affecting the test data during the testing process, thus improving the practicality of the device.

[0008] Preferably, it also includes support rollers and a rotating top plate. Multiple sets of support rollers are installed at the lower part of the bearing groove of the support frame, and a rotating top plate is installed on the vertical plane inside the bearing groove of the support frame through bearings. Multiple sets of support rollers provide auxiliary support for the steel roll, and the cooperation between multiple sets of support rollers and the rotating top plate facilitates the rotation of the steel roll itself, thereby enabling the equipment to quickly detect different areas on the steel roll and improving the practicality of the device.

[0009] Preferably, the cleaning device includes a brush cleaning roller and a geared motor. The brush cleaning roller is installed in the lower part of the frame, and the geared motor is installed on the right end face of the frame. The output end of the geared motor is connected to the brush cleaning roller. Turning on the geared motor transmits power to the brush cleaning roller, causing the brush cleaning roller to rotate. The rotating brush cleaning roller cleans the side of the steel roll. In conjunction with multiple sets of support rollers and a rotating top plate, the steel roll rotates and adjusts itself, improving the practicality of the device.

[0010] Preferably, the transverse movement device includes a cross-shaped limiting groove, a transverse platform, guide rods, lead screws, a dual-output reducer, and a motor. The upper part of the frame is provided with a cross-shaped limiting groove. The main body of the transverse platform is installed in the cross-shaped limiting groove, and the lower part of the transverse platform extends to the lower side of the cross-shaped limiting groove. A set of guide rods is provided on the left and right sides of the cross-shaped limiting groove, and a set of lead screws is provided on the left and right sides of the lower side of the cross-shaped limiting groove. A dual-output reducer is installed on the upper part of the right end face of the frame, and a motor is installed on the dual-output reducer. The two output ends of the dual-output reducer are connected to the two sets of lead screws respectively. The transverse movement of the transverse platform is limited by the cross-shaped limiting groove and the two sets of guide rods, reducing the vibration amplitude of the transverse platform during transverse movement. Turning on the motor transmits power to the two sets of lead screws through the dual-output reducer, causing the two sets of lead screws to rotate synchronously, thereby moving the transverse platform left and right within the cross-shaped limiting groove to select the detection area, improving the practicality of the device.

[0011] Preferably, the device also includes a hydraulic cylinder and a detection pressure head. The hydraulic cylinder is installed on the upper surface of the transverse platform, and the moving end of the hydraulic cylinder extends through the lower surface of the transverse platform to the lower side of the transverse platform. The detection pressure head is installed on the moving end of the hydraulic cylinder. By controlling the extension of the hydraulic cylinder, the detection pressure head is pressed against the surface of the steel roll, thereby squeezing the surface of the steel roll and leaving an indentation. The indentation data can then be detected, which improves the practicality of the device.

[0012] Preferably, the device also includes a collection frame, a discharge trough, spiral blades, and a rotating handle. A collection frame is located at the bottom of the frame, and a discharge trough is located at the bottom of the collection frame. Spiral blades are installed in the discharge trough, and a discharge port is located on the right end face of the discharge trough. The right side of the spiral blades extends through the discharge port of the cross-shaped limiting groove to the right side of the frame. A rotating handle is installed on the right end face of the spiral blades. The collection frame collects the debris generated during the brush cleaning roller cleaning process, causing the debris to fall into the discharge trough, reducing the impact on the operating environment. Rotating the rotating handle drives the spiral blades to rotate, thereby discharging impurities from the discharge trough, reducing the labor intensity of operators during maintenance and improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the steel roll is horizontally supported and its spatial position is fixed by the fixing device, while the side detection area of ​​the steel roll is adjusted by loosening the edge of the steel roll, the surface of the steel roll is cleaned by the cleaning device to reduce the influence of debris on the detection data, and the different horizontal positions on the steel roll are detected by the transverse movement device, which improves the practicality of the device.
