This standard replaces GB/T 14331-1993 "Automatic coil spring machine accuracy". This standard compared with GB/T 14331-1993, in addition to editorial changes to the main technical content changes are as follows. --- increase the normative reference documents; --- increase the inspection project; --- modified the accuracy of tolerance; --- modified the test method. This standard is proposed by the China Machinery Industry Federation. This standard by the National Forging Machinery Standardization Technical Committee (SAC/TC220) centralized. This standard is responsible for drafting unit. Shengzhou Golden Lion Spring Machinery Co., Ltd., Luoyang Machine Tool Co., Ltd., Shengzhou Machinery Industry association. The main drafters of this standard. Li Hongliang, Li Zhimin, Ding Ming, Xu Wei, Chang Yuejun, Wang Haiyan, building. This standard replaced the previous version of the standard release. --- GB/T 14331-1993. Automatic coil spring machine accuracy1 ScopeThis standard specifies the accuracy of the automatic coil spring machine. This standard applies to the automatic coil spring machine for cold roll.2 normative reference documentsThe following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. Cold - rolled cylindrical helical springs - Technical conditions - Part 1. Tension springs Cold - rolled cylindrical helical springs - Technical conditions - Part 2. Compression springs GB/T Cold - rolled cylindrical helical springs - Technical conditions - Part 3. Torsion springs GB/T Specification for small cylindrical helical springs GB/T Cold - drawn carbon spring steel wire GB/T Representation and Judgment of Numerical Correction Rule and Limit Value of GB/T 8170 General rules for precision testing of forging machinery GB/T Cast iron feet3 inspection requirements3.1 Accuracy inspection shall comply with the provisions of GB/T 10923. 3.2 Accuracy should be adjusted before the level of automatic coil spring machine, the level should not exceed 0.20/1000. 3.3 Automatic roll spring machine The front plane is the datum of the tests 4.1.2, 4.1.3, 4.1.4 and 4.1.5. Its flatness tolerance of 1000mm Length is not greater than 0.06mm. 3.4 The geometric accuracy of this standard can be tested in any order. 3.5 The accuracy of the accuracy of the automatic coil spring machine, according to the actual test length calculation, the calculation results according to GB/T 8170 repair to the micron digit. When the tolerance value is less than 0.01 mm, 3.6 cast iron footage accuracy should not be less than GB/T 24760-2009 level 1 accuracy.4 precision test4.1 Geometric accuracy test 4.1.1 The coincidence degree of the bearing surface of the lower feed shaft 4.1.1.1 Inspection method The flat surface of the work surface attached to the lower feed shaft shoulder bearing surface, in the distance L, with a ruler to measure the level of workpieces and the lower feed shaft The gap between the shoulder bearing surfaces (see Figure 1). The degree of coincidence error is calculated according to the maximum thickness of the insertable stopper. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 14331-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 14331-2017_English as soon as possible, and keep you informed of the progress.
