Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling devices, in particular to a cooling device for an upset forging sample. Background Art
[0002] The upset forging test method for metal materials involves applying pressure along the specimen's axis at room temperature or in a hot state to compress the specimen. The test examines the metal's ability to withstand plastic deformation during upset forging at a specified forging ratio and reveals surface defects. This method is primarily used to assess the quality of metal materials during mass production of die-cast parts. The earliest upset forging test standard was published in September 1963. After its first revision in July 1981, it became GB / 233-1982, now GB / T233-2000. The new standard is equivalent to GB / T8817-1982, "Methods for Upset Forging Tests of Metals." GB / T233 and GB / T8817 are essentially identical in content, with only minor differences: the former uses forging ratios rather than relative forging rates and adds requirements for height deviation of specimens after upset forging. GB / T233-2000 also specifies several types of testing equipment, but from 1963 until today, the original testing equipment used in the standard has remained the same.
[0003] When our company conducts hot upsetting tests, we first heat the specimens to 1050°C and keep them warm for 30 minutes. We then take them out of the furnace one by one for upsetting tests. After the test, we place the hot upsetting specimens on a cooling rack for cooling. After cooling, we observe whether there are any cracks or folds visible to the naked eye, and fill in the test results in the report. Placing the hot upsetting specimens on the cooling rack during cooling will cause temperature stress, structural stress, and residual stress, which may form cracks. In addition, the cooling rack currently used is a planar structure with a large contact area with the specimen, which may result in differences in cooling temperature between the upper and lower surfaces and the core of the specimen, thus affecting the accuracy of the test results. At the same time, the plate surfaces between the various layers of the cooling rack are solid structures, which hinder the sufficient cooling of the specimen. Secondly, the oxide scale that falls off the surface of the specimen will fall onto the cooling rack, which requires special cleaning after the test. For this reason, we have proposed a cooling device for upsetting specimens. Utility Model Content
