Description

Technical Field

[0001] The invention relates to the technical field of plastic forming metal processing, and in particular to a high-temperature blank heating and automatic placing device based on a cupping test. Background Art

[0002] As an important material performance testing method, the cupping test is widely used in many fields such as metal material research, automobile manufacturing, aerospace, etc. It is used to evaluate key indicators such as the material's plastic deformation ability and crack resistance.

[0003] However, the traditional cupping test faces many challenges when dealing with high-temperature billets. During the stage of heating high-temperature billets, it is difficult for conventional heating devices to accurately maintain a specific high-temperature environment, and the temperature fluctuates greatly, making it impossible to ensure the uniformity of heating of the billet, which greatly reduces the reliability of the test data. In addition, there is a lack of effective connection between traditional heating equipment and cupping testers. During the process of transferring the billet from the heating device to the testing machine, heat is severely dissipated and the temperature drops sharply. This not only affects the actual performance of the material during the test, but may also cause changes in the internal structure of the material due to temperature changes, further interfering with the accuracy of the test results.

[0004] In the process of placing blanks, most of them rely on manual operation. Operators need to come into close contact with hot blanks in a high-temperature environment, which poses a great threat to personal safety and easily causes safety accidents such as burns. At the same time, manual operation is inefficient and difficult to meet the production needs of large-scale and rapid testing. In addition, the accuracy of manual placement is limited, and it is difficult to ensure the consistency of the blank placement position each time, which increases the uncertainty of test errors.

[0005] In addition, the traditional cupping test device has relatively independent parts, low automation integration, poor coordination between various links, and it is difficult to build a coherent and smooth test process. From heating to placement to test execution, the entire process is difficult to achieve seamless docking and precise control, which is not conducive to efficient, stable and accurate cupping tests, and cannot meet the increasing requirements of modern industry for material performance testing.

[0024] It can be understood that, by providing a furnace door 18 connected to the main frame 16, it is mainly responsible for heat preservation and heat insulation, ensuring the concentration and stability of heat in the furnace; by providing a furnace chamber 17 in the middle of the main frame 16, it is convenient to provide a heating space for the test blank 27; by providing a blank heating plate 21 located at a specific position in the furnace chamber 17 and having a groove design, the test blank 27 is centrally positioned during the heating process to ensure the uniformity of heating. At the same time, both sides of the blank heating plate 21 are adjacent to a high-temperature resistant ceramic conveying plate 28. When the test blank 27 is placed, both ends of the blank protrude from the blank heating plate 21 and can be overlapped on the conveying plate to facilitate subsequent transportation operations; A push rod group 19 consisting of two groups of parallel and symmetrical electric push rods 24 is provided, and the push rod group 19 is connected to the main frame 16 and the rear furnace door 20 at the same time, so that the rear furnace door 20 can be automatically opened and closed through the precise pushing and pulling action of the push rod group 19, providing a convenient transportation channel for the heated test blanks 27; a vacant area 22 is provided which fully considers the installation and operation requirements of the conveying mechanism 4 and the high-temperature blank placement mechanism 3, so as to ensure the efficient operation of the entire heating furnace; the special heating furnace 2 can also be used as a common heating furnace when the cupping test is not carried out through the multifunctional design, so as to meet the diverse needs of blank heating in daily experiments, and improve the use efficiency and flexibility of the equipment.

[0025] like Figure 5 , Figure 6 As shown, the high-temperature blank placement mechanism 3 includes a base plate 23, an electric push rod 24, a semicircular push plate 25, an opening and closing movement arm 26, a high-temperature resistant ceramic conveying plate 28, a transverse opening and closing bracket 29 and a transverse movement slide rail 30; two groups of parallel electric push rods 24 and two groups of transverse movement slide rails 30 are installed on the base plate 23; the front part of each group of electric push rods 24 is connected to one end of a semicircular push plate 25, and the other end of the semicircular push plate 25 is connected to one end of two symmetrical opening and closing movement arms 26; the other end of each opening and closing movement arm 26 is connected to a transverse opening and closing bracket 29, and the middle part of the transverse opening and closing bracket 29 is slidably matched with the transverse movement slide rail 30; a high-temperature resistant ceramic conveying plate 28 is connected to the upper part of the transverse opening and closing bracket 29, and the test blank 27 is supported and placed at both ends of the middle part of the two high-temperature resistant ceramic conveying plates 28.

The other end of each opening and closing motion arm 26 is connected to a transverse opening and closing bracket 29, and the middle part of the transverse opening and closing bracket 29 is assembled with the transverse motion slide rail 30 in a sliding fit, so that when the electric push rod 24 is pushed forward, the transverse opening and closing bracket 29 can smoothly realize the opening and closing movement. The upper part of each transverse opening and closing bracket 29 is connected to a high-temperature resistant ceramic conveying plate 28, and the two ends of the test blank 27 are supported and placed on the two high-temperature resistant ceramic conveying plates 28, and the opening and closing movement of the transverse opening and closing bracket 29 is transmitted to the high-temperature resistant ceramic conveying plate 28, so as to realize the precise placement operation of the test blank 27. At the same time, since the high temperature resistant ceramic conveying plate 28 has been heated, it can have a certain heat preservation effect on the test blank 27, thereby effectively reducing the temperature drop of the high temperature test blank 27 during the transportation process.

[0027] like Figure 7 As shown, the conveying mechanism 4 includes two sets of guide rails 31, two sets of lead screws 32, a slider 33 and a servo motor 34; the two sets of guide rails 31 are installed in parallel and symmetrically in the vacant area 22 of the special heating furnace 2, and each set of guide rails 31 is equipped with a set of lead screws 32, two sliders 33 and a servo motor 34.

By cooperating with the controller 40, the equipment parameters can be adjusted to achieve orderly coordination of various mechanisms during the test process.

[0030] When the high-temperature blank heating and automatic placement device based on the cupping test described in this embodiment is used, first, the test blank 27 that needs to be cupped is placed on the blank heating plate 21 in the special heating furnace 2, and the two ends of the test blank 27 are overlapped on the high-temperature ceramic conveying plate 28. After closing the furnace door 18, the heating program is started, and the heating temperature, time and other parameters are set by the control system 6. The heating plate of the special heating furnace 2 starts to work, so that the test blank 27 is evenly heated to the specified high temperature. After the heating is completed, the push rod group 19 pushes the rear furnace door 20 to open, and the servo motor 34 of the conveying mechanism 4 drives the screw rod 32 to rotate, driving the slider 33 to move on the guide rail 31, so that the high-temperature ceramic conveying plate 28 with the high-temperature blank is placed is conveyed from the vacant area 22 of the special heating furnace 2 to the high-temperature blank placement mechanism 3. Next, the electric push rod 24 of the high-temperature blank placement mechanism 3 is started, pushing the semicircular push plate 25 to move. The semicircular push plate 25 drives the transverse opening and closing bracket 29 to move on the transverse motion slide rail 30 with the help of the opening and closing motion support arm 26, so that the two high-temperature resistant ceramic conveying plates 28 are close to each other, and the high-temperature blank is accurately pushed to the stamping area between the upper pressure ring 12 and the lower pressure ring 14 of the cupping tester 1. At this time, the hydraulic device 10 of the cupping tester 1 starts to work, driving the die 13 to perform a stamping test on the high-temperature blank under the guidance of the stamping guide light rod 11. The whole process is monitored and controlled in real time by the control system 6 to ensure the precise operation and connection of each link. The test data can also be recorded and analyzed through the control system 6, and finally the high-temperature blank performance test based on the cupping test is completed efficiently and accurately, providing a reliable basis for material research and quality control in the field of plastic forming metal processing.

[0031] The high-temperature stock heating and automatic placement device based on the cupping test of the above-mentioned implementation scheme effectively achieves the automatic and precise control of the heating and placement of the high-temperature stock. In the heating stage, the special heating furnace 2, relying on its scientific structural layout and precise temperature control system, heats the test stock 27 to a precise high-temperature state according to the preset, effectively ensuring the accuracy and stability of the test starting temperature, and effectively overcoming the difficulties of significant temperature fluctuations and uneven heating in the traditional heating mode. In the process of transmission and placement, the transmission mechanism 4 is closely coordinated with the high-temperature stock placement mechanism 3, and the smooth transportation of the high-temperature stock between different stations and the precise placement in the cupping tester 1 are achieved through the orderly linkage of the guide rail 31, the screw rod 32, the electric push rod 24 and other components, which greatly improves the operating efficiency and placement accuracy, and avoids the instability and safety hazards of manual operation. At the same time, under the overall coordination of the control system 6, each part of the device realizes efficient information interaction and collaborative operation, and builds a complete, smooth and reliable working link from the setting of heating parameters to the final test data recording, which significantly enhances the overall quality and credibility of the cupping test.
