Accident appraisal of stamping machine tool

At present, most small and medium-sized enterprises still use manual work methods. In the stamping production of continuous and repeated operations, the high-speed and high-productivity environment causes operators to consume a lot of physical energy when repeatedly picking up and feeding materials by hand thousands of times. Over time, it is easy to make mistakes and cause accidents. Moreover, accidents are prone to occur if managers do not pay attention to production safety and if rules and regulations are not strict.
punch equipment itself has defects, lack of safety protection devices, clutches and brakes that are not flexible and reliable enough, the electrical control structure suddenly loses control and causes continuous punching, and accessory tools are defective, etc., all of which may lead to major accidents.
Zhongke Testing and Appraisal Institute can provide stamping machine tool accident identification services and make accurate identifications of trace evidence analysis and accident cause analysis in various stamping machine tool accidents.

1. Human reasons. At present, most small and medium-sized enterprises still use manual work methods. In the stamping production with continuous and repeated operations, the high-speed and high-productivity environment causes operators to consume a lot of physical energy when repeatedly picking up and feeding materials by hand thousands of times. Over time, it is easy to make mistakes and cause accidents. In addition, accidents are prone to occur if managers do not pay attention to production safety and if rules and regulations are not strict.
2. Device security. For example, there may be defects in the punching equipment itself, lack of safety protection devices, insufficient flexibility and reliability of clutches and brakes, sudden loss of control of the electrical control structure resulting in continuous punching, defective accessory tools, etc., all of which may result in major operational accidents.
3. Unsafe state of mold. The unsafe state of the mold is directly related to the personal safety of operators and the normal progress of stamping production. It is important to design the mold scientifically and safely.
4. Stamping environment. Some stamping workshops have messy stacks of materials, small spaces, insufficient lighting, ventilation and other conditions, and poor working environments such as excessive noise can also cause accidents.

A stamping machine tool injured someone in a company. Our company was entrusted by the court to conduct a technical appraisal of the "stamping machine tool" accident and find out the cause of the accident. .
appraisal analysis results:
Our appraisers went to the site of the incident to conduct an inspection, and representatives of the company involved cooperated and made detailed statements. Based on what was learned during the on-site inspection, the analysis of the causes of the injury incident involving the "stamping machine tool" is as follows:
First of all, our company's personnel did not find any abnormal readings on the clutch brake pressure gauge of the "stamping machine tool" involved during the inspection, and no abnormal braking conditions or abnormal alarms on the touch screen were found during on-site operations. It can be seen that the clutch brake of the "stamping machine tool" involved has normal braking performance.
Secondly, our company’s personnel conducted an on-site inspection and found that the photoelectric protection device of the “stamping machine tool” involved had a “blind spot”.
Finally, when operating the "stamping machine tool" involved, the employee involved failed to operate in accordance with the operating instructions and warning regulations.
