Description

Technical Field

[0001] This invention relates to a mounting device, and more particularly to a mounting device for arranging samples in a thermal simulation testing machine, belonging to the field of design and manufacturing technology of accessories for thermal testing equipment for metallic materials. Background Technology

[0002] Gleeble equipment is widely used in the global steel, welding, materials research, and aerospace industries, playing a vital role in understanding material properties, creating thermal processing method diagrams, improving productivity, reducing costs, and enhancing product quality. It is one of the most widely used pieces of equipment in new material development, serving as a pilot production line. This equipment can quickly and easily simulate the hot processing of materials, such as forging and rolling, and can also be used to test the high-temperature properties of materials. This equipment plays a crucial role in new material development, especially in steel research institutions, where it is one of the most frequently used large-scale pieces of equipment, handling a wide variety and large number of experiments, making it particularly important to improve experimental efficiency. Furthermore, some simulations and numerical simulations rely on thermal simulation testing machines to provide fundamental data, making the reliability of experimental results of paramount importance.

[0003] A crucial step in thermal simulation experiments is sample mounting before the experiment. The speed of sample mounting directly impacts experimental efficiency, while the appropriateness of the mounting position determines the accuracy and reliability of the results. Currently, thermal simulation experiments primarily involve three different sample shapes: cylindrical, rod-shaped, and cuboid. When samples are mounted between two compression shafts as required, their center points differ in both the vertical and horizontal directions. In daily work, this relies on manual and visual coordination by staff to find the center point for mounting, which is not only time-consuming but also inevitably results in deviations from the ideal center point. This centering deviation affects the material's rheological deformation; furthermore, if the centering is misaligned laterally, the processed area of ​​the sample will not be precisely centered, affecting the results of subsequent impact tests or the assessment of the material's thermal processing properties. Summary of the Invention

Finally, utilizing the composite position adjustment component's ability to arbitrarily adjust the three-dimensional spatial position of the test sample within a certain range, the test sample is installed at the specified position between the two compression axes of the simulation testing machine. This achieves both convenience in sample mounting operations and effectively improves the quality of sample mounting, ensuring that the test sample is always positioned precisely between the two compression axes of the thermal simulation testing machine, thus achieving the goal of accurate sample mounting. To improve the automation level of control, the mounting device described in this application further includes an automatic control component.

[0020] Furthermore, the horizontal position adjustment assembly of this application includes a sliding body 6, a support arm 7, and a caster wheel 8.

[0021] In summary, the technical solution provided in this application also has the following advantages: First, the electric control system of the mounting device automatically controls the left and right movement of the sliding body device, which makes it easier to find the horizontal center point and center the sample in the horizontal direction.

[0022] Secondly, the electric control system of the mounting device automatically controls the up and down movement of the lifting platform, making it easier to find the vertical center point of the sample and to center the sample in the vertical direction.

[0023] Third, by adjusting the angle between the two support plates, the problem of mounting experimental samples of various shapes was solved. The electric control system accurately locates the center point, saving time and effort, improving precision, and increasing work efficiency.

[0024] Fourth, the mounting device provided in this application is highly practical, meeting the needs of all precise sample mounting in thermal simulation experiments. It also boasts a high degree of automation, making sample mounting convenient and quick. The electric control device allows for precise displacement control in both horizontal and vertical directions, significantly improving work efficiency and reducing the workload for staff. Furthermore, it enhances the accuracy and reliability of experimental results.

[0025] The technical solution of this application will be further described below through specific embodiments: The mounting device designed in this application includes a solid right-angled trapezoidal base made of stainless steel. The base is designed in the shape of a right-angled trapezoid, with three right-angled sides and one inclined surface. The inclined surface of the trapezoid has an inclination angle of 30°, matching the bottom surface of the sample chamber on which the base rests. The angle between the bottom surface of the sample chamber and the horizontal plane is 30°. The purpose is to ensure that the upper surface of the base is horizontal when placed on the bottom surface of the sample chamber. The upper base of the trapezoid is a rectangle of 20×80mm, with two integrated legs on the left and right sides of this surface to facilitate locking the base into the grooves on the bottom surface of the sample chamber and prevent the base from sliding. The legs are 20mm high, 5mm wide, and 2mm thick. The largest right-angled face of the trapezoid is 80×160mm (the horizontal surface of the base), and the other surfaces of the trapezoid are automatically determined by the data given above.

[0026] Weld a 16mm diameter, 80mm long round bar to the bottom surface of the base (near the 20×80mm top surface), at a distance of 20mm from the 80mm side. The length of the round bar is parallel to the 80mm side length. The round bar is made of stainless steel and has a scale on it.

[0027] A sliding body with a semi-circular groove and omnidirectional casters rests on top of the round bar. The sliding body is a rectangular block made of stainless steel. Its upper surface is a 40×40mm square with a thickness of 10mm. A semi-circular groove with a radius of 8.2mm is located in the center of the bottom of the cuboid, and the groove's direction is parallel to the direction of the round bar. This groove fits snugly with the round bar mounted on the base. Support arms and omnidirectional casters are installed at the four corners of the sliding body, facilitating horizontal movement of the sliding body. The support arms are connected to the cuboid and the omnidirectional casters by screws. The height of the support arms and omnidirectional casters is 10mm. When the experimental sample needs to find its horizontal center point, the sliding body can be moved horizontally left and right using a PLC control device mounted on it. The controllable left and right movement range is 0-20mm, with a displacement control accuracy of 0.1mm.

[0028] A 20mm diameter, 2mm thick, stainless steel truncated cone is mounted and fixed to the center of the upper surface of the sliding body via screws, and is electrically controlled by a PLC for lifting. The lifting arm is made of 10×5×2mm stainless steel sheets. The stainless steel sheets are connected by 40CR QBQ pins. The inherent height of the lifting platform is 30mm, the controllable lifting range is 0-10mm, and the displacement control accuracy is 0.1mm.

[0029] An L-shaped bracket is mounted on the truncated cone. The bracket is a single piece made of stainless steel. It is connected and fixed to the center of the truncated cone of the lifting platform via screw holes. The bracket plate is 2mm thick and 10mm wide. The horizontal plate of the bracket is fixed to the truncated cone with a single screw. The horizontal plate of the L-shaped bracket is a 10×10mm square. The vertical plate of the bracket is a 10×34.3mm rectangle. A metal ring with M6 internal threads is welded to the center of each of the two sides of the vertical plate. On both sides of the top of the vertical plate, there are four ear-like structures perpendicular to the vertical plate. These ear-like structures are square, 10×10mm in size, and 2mm thick. The upper edge of each ear-like structure is 40mm from the horizontal plate. To accommodate the 90° angle formed by the adjustment of the two support plates, the right angle of the ear-like structure is cut off at the top of the vertical plate. The hypotenuse of this right-angled triangle is 4mm, and the right-angled triangle is an isosceles right triangle. There is a screw hole in the center of the square ear structure, which is used to insert and fix two stainless steel round bars with a diameter of 8mm. The ends of the round bars are threaded with an M6 thread size to match the screw hole on the ear structure.

[0030] Connected to the 8mm round bar is a top support plate. One end of the support plate has a coiled 8mm diameter cylinder that winds the support plate onto the round bar. There is one support plate on each side of the top of the vertical plate. The support plate serves as a mounting platform for the experimental sample. The cylinder at one end of the support plate allows it to rotate around the round bar, thus adjusting the angle between the two support plates. The parallel surface of the support plate is 10mm wide, 34.3mm long, and 2mm thick. A metal ring with an M6 internal thread is welded to the center of the bottom surface of each support plate.

[0031] In addition, two retractable circular stainless steel support rods (similar to retractable clothes hangers) are designed, with rings of the same specifications as the aforementioned internally threaded metal rings welded to both ends of the support rods. The rings at both ends of the support rods are stacked with the rings on the plates, and the rods are fixed to the plates with screws. After one end of the support rod is fixed to the metal ring of the vertical plate with screws, the length of the support rod is adjusted so that the included angle between the two support plates is 90°, and the other end of the support rod is fixed to the ring of the support plate with screws. At this point, the two support plates at a 90° angle are used to hold circular and cuboid samples. The length of the support rod is adjusted again so that the included angle between the two support plates is 180°, and the other end of the support rod is fixed to the support plate with screws. The two support plates at a 180° angle are used to hold flat plate samples, plane strain compression samples, and other experimental plate-shaped samples.

[0032] Example 1 Take a cylindrical high-temperature compression heat simulation test sample as an example. Sample dimensions: diameter 8mm, length 12mm.

[0033] Connect the No. 9 screw hole of the lifting platform to the No. 7 screw hole of the sliding body with screws to secure them. Connect the No. 14 screw hole of the "L"-shaped bracket to the No. 13 screw hole of the lifting platform with screws to secure them. At this point, the sliding body, the lifting platform, and the "L"-shaped bracket are integrated into one unit. Place the groove of the lifting platform and the sliding body on the round bar of the base, with the center of the sliding body coinciding with the midpoint of the round bar's length.

[0034] Connect one end of the support rod to the vertical plate with screws, adjust the length of the support rod so that the angle between the two support plates is 90°, connect the other end of the support rod to the metal ring of the support plate, and place the cylindrical sample between the two support plates.

[0035] The center point of the anvil is 100mm from the base platform. The inherent height of the lifting platform is 30mm, the inherent height of the "L" support frame is 34.3 + 2 = 36.3mm, and the height of the sliding body is 20mm. Based on the 90° angle of the support plate and the radius of the cylindrical sample, the distance from the center of the sample to the boundary line of the 90° angle of the support plate is calculated to be 5.7mm. To align the center of the sample with the center of the anvil, the automatic lifting platform is remotely controlled, causing the support frame to move upward by 100 - 30 - 36.3 - 20 - 5.7 = 8mm. At this point, the experimental sample mounted on the support frame is accurately centered in the vertical direction.

[0036] Adjust the horizontal position of the slider using the remote control so that the right end of the sample is flush against the surface of the right anvil. The initial positions of the slider's center and the support frame's center are at the middle of the 16mm round rod. The horizontal distance between the slider's center and the right fixed compression shaft is 18mm, the length of the anvil extending beyond the compression shaft is 10mm, the distance between the slider's center and the anvil surface is 18-10=8mm, and the horizontal distance between the sample's center and the anvil is 8-12÷2=2mm. Using the remote control, move the slider 2mm towards the right fixed compression shaft. At this point, the experimental sample mounted on the support frame is accurately positioned horizontally.
