Guangdong Province announced the results of spot check on the product quality of general mechanical equipment and its parts

in accordance with the product quality law of the people's Republic of China, the measures for the administration of product quality supervision and spot check, the regulations of Guangdong Province on product quality supervision and other relevant laws and regulations, Guangdong Provincial Bureau of quality supervision Special supervision and spot check on product quality were carried out for 4 kinds of products including general mechanical equipment and its parts (forging machinery/Woodworking Machinery). The spot check results are hereby released

general machinery and equipment and their parts and components (forging machinery/Woodworking Machinery)

this time, 80 batches of general machinery and its parts and components (forging machinery/Woodworking Machinery) products produced by 80 enterprises in 6 cities (districts) including Guangzhou, Foshan, Dongguan, Zhongshan, Jiangmen and Shunde were spot checked. After inspection, 5 batches of products produced by 5 enterprises were found to be unqualified, and the discovery rate of unqualified products was 6.3%. The non-conforming items involve three items: basic design requirements of forging machinery, mechanical hazards in the work (or operation) danger zone (within the mold area), control and monitoring system; The starting, normal stopping, mechanical feeding and electrical equipment safety of woodworking machinery. (see the table below for details)

2016 Guangdong general machinery and its parts (forging machinery/Woodworking Machinery) product quality special supervision and spot check list of unqualified products and their manufacturers

the 80 production enterprises (80 batches) to be sampled this time include 3 large enterprises (3 batches), 5 medium enterprises (5 batches), 72 small enterprises (72 batches), large, medium The proportion of small enterprises in the total number of enterprises sampled was 3.75%, 6.25% and 90.0% respectively. Through random inspection, it was found that five batches of products produced by five enterprises were unqualified, all of which were small-scale key enterprises, scientific research institutions, colleges and universities, industrial alliances, associations and other enterprises. The discovery rate of unqualified products of small-scale enterprises was 6.9%

this spot check is based on GB 17120-2012 technical safety conditions for forging machinery, GB 27607-2011 technical safety requirements for mechanical presses, GB 26483-2011 noise limits for mechanical presses, GB 28241-2012 technical safety requirements for hydraulic presses, GB 26484-2011 noise limits for hydraulic presses, GB 28240-2012 technical safety requirements for plate shears, and GB 24389-2009 noise limits for shearing machinery GB 28243-2012 safety technical requirements for hydraulic sheet metal bending machines, GB 24388-2009 noise limits for bending machines, as well as the current effective enterprise product standards, product quality indicators and requirements that have been filed, the basic requirements for the design of forging machinery products (mechanical presses, hydraulic presses, plate shears, hydraulic sheet metal bending machines), and the mechanical hazards in the work (or operation) danger area (within the mold area) have been detected through a large number of experiments, The control and monitoring system, mold adjustment, stroke adjustment, maintenance and lubrication (operation mode), other mechanical hazards, slip, trip and fall hazards, measures to prevent other hazards (other hazards), signs, operation instructions and other 9 items were inspected; General requirements for other forging machinery products, transmission system, clutch and brake, balance device, overload protection device, control device, electrical system, hydraulic system, pneumatic system, lubrication system, noise, vibration, local lighting, radiation, materials and materials, ergonomics, safety protection device, fixed facilities for entering forging machinery, spring, clamping, clamping mechanism, parts loading and unloading, 22 items such as information were used for inspection. According to GB 12557-2010 general rules for safety of woodworking machine tools and the current effective enterprise product standards and product quality indicators and requirements that have been filed, the starting, normal stopping, emergency stopping, mechanical feeding of woodworking machine products are generally made. The distance from the bottom of the oil tank of the hydraulic pump of the carton pressure tester to the outside diameter of the pipe is 2 times of the dynamic system, the obstacles entering the moving parts of the machine tool, the requirements for safety protection devices, wood chips Dust and harmful gas emission, noise, electrical equipment safety and other 10 items were inspected

with regard to the unqualified production enterprises in this spot check, the Guangdong Provincial Bureau of quality supervision has instructed the relevant local and municipal quality supervision departments to issue a notice of rectification in accordance with the product quality law of the people's Republic of China and the measures for the administration of product quality supervision and spot check, order the enterprises to stop producing and selling unqualified products, make rectification within a time limit and organize reexamination according to law; The production enterprises with serious quality problems shall be investigated and dealt with according to law
