Description

Technical Field

[0001] The invention belongs to the technical field of molded product detection, and in particular relates to a product detection platform for MIM metal injection high-strength steel molding and a use method thereof. Background Art

[0002] MIM metal injection molding technology is a technology that mixes metal powder with a binder and then uses an injection molding process to make complex-shaped parts. After injection molding, the metal powder needs to go through multiple testing processes to detect whether its performance and quality meet the standard requirements. Existing devices generally place the product to be tested on the test bench to ensure that the product is stable and easy to test, check the operating status of each part of the test bench, and ensure that the measuring instruments, control systems, etc. are in normal working condition. After using the instrument for testing, a detailed test report will be generated based on the test results, recording the test process, measurement results and evaluation conclusions.

[0003] For MIM metal injection high-strength steel products with high oil content, if degreasing treatment is not performed before measurement, the high oil content may reduce the mechanical properties of the material, such as hardness, compressive strength, and yield strength. In addition, if the oil is not completely evaporated, pores or cracks will be formed, further weakening the mechanical properties of the material. On the other hand, density detection is an important means to evaluate the density and quality of materials. High oil content will cause the test results to deviate from the expected value.

[0027] In summary, a method for using a product testing table for MIM metal injection high-strength steel forming is also proposed, which is carried out using the above-mentioned device and includes the following steps: S1, putting the organic solvent and the finished product into the degreasing solvent cylinder 5 for soaking; S2, taking out the fully soaked finished product through the pushing assembly 7 and placing it on the moving slide 6; S3, moving the slide 6 to move the finished product to the pore detection assembly 8 to detect whether the finished product is foamed, and if it is foamed, it is judged to be unqualified; S4, after drying, the unfoamed finished product is placed in the overflow water tank 4, and the overflow water volume in the water collecting cover 12 is recorded and the density of the sample is calculated using the density formula; S5. Place the finished product on the upper end of the compression anti-deformation detection component 9 and test the anti-deformation degree of the finished product through compression test Working principle: Before use, first put organic solvent into the degreasing solvent cylinder 5. After controlling the clamping arm body 31 to clamp the finished product, start the stepping motor 24 above the fixed bracket 3 to drive the threaded rod 25 to rotate. The linear shaft 26 passes through and sleeves the socket support 27 to achieve the effect of restricting rotation. Under the cooperation of the internal thread groove 32 and the screw rod of the threaded rod 25, the clamping arm body 31 at the outermost side of the bottom positioning plate 28 is moved above the degreasing solvent cylinder 5. Then start the second hydraulic cylinder 29 to drive the clamped finished product to extend into the degreasing solvent cylinder 5 and move up and down repeatedly, so as to remove the oil stains on the surface of the finished product. Then lift the finished product, reverse start the stepping motor 24 and place the finished product on the moving slide 6. Then start the servo motor 34, and the synchronous belt 36 completes the transmission effect under the same-speed rotation of the two sets of pulleys 37. Cooperating with the meshing internal pressure seat 38, the upper moving slide 6 realizes the movement in the X-axis direction to the inside of the windproof chamber 21. Then turn on the ultrasonic bubble detection sensor 22. When there are bubbles in the finished product, due to the large acoustic impedance difference between the solid and the gas, this impedance mismatch will form an acoustic mirror between the solid and the gas, reflecting the ultrasonic wave back to the direction of the transmitter, thus prompting the existence of bubbles, and the product is judged as unqualified. On the other hand, the qualified product can be surface-dried by multiple groups of electric heating tubes 23. Before the sample enters the overflow water tank 4, weigh it, and then move the finished product into the overflow water tank 4 filled with water. After completely immersing the sample in water, record its mass in water. During this process, the overflowed water flows to the overflow trough and then into the water collecting cover 12 through the overflow pipe 11. The buoyancy force received by the sample in water is equal to the weight of the water in the water collecting cover 12. From this, the volume of the sample V_drain = (m_before - m_after) / ρ_water can be calculated. Then use the density formula ρ = m_before / V_drain to calculate the density of the sample. The operation is simple and economical. After the density detection is completed, the finished product can be clamped to the rotating turntable 16, and the first hydraulic cylinder 13 above is started to push the lower pressing plate 15 against the top surface of the finished product. As the pressure gradually rises to the rated value, then reverse start the first hydraulic cylinder 13 to separate the lower pressing plate 15 from the finished product. Then start the DC motor 18 to drive the rotating turntable 16 to rotate. The strain sensor 20 converts the deformation generated when the object is subjected to an external force into a measurable electrical signal output and feedbacks it to the control end, and cooperates with the rotating finished product to complete the comprehensive anti-deformation detection.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
