Pneumatic hammer quality appraisal

pneumatic hammer uses compressed air as its power core and plays a key role in workpiece forging, riveting, stamping and other processing. In the field of automobile manufacturing, it accurately completes the tapping and forming of parts; in the aviation industry, it assists in the assembly of high-precision components; in metal processing scenarios, it takes on the important task of material shaping. Compared with pneumatic hammers, hydraulic hammers and electric hammers, pneumatic hammers occupy a unique position in the industrial production chain due to their stable power output and adaptability to complex working conditions. They not only improve processing efficiency, but also ensure processing accuracy, making them indispensable equipment in modern industry.

In industrial production, pneumatic hammer quality disputes occur frequently. Judicial disputes focus on multiple dimensions: whether the equipment complies with the contract or national standards, whether there are safety hazards, the definition of losses caused by quality problems, etc. At this time, the quality appraisal of pneumatic hammers has become the key. It analyzes the quality of equipment through scientific and technical means, provides a basis for court judgments, resolves disputes, and maintains judicial fairness and market order. The conclusion of the quality appraisal of the pneumatic hammer has a direct impact on the judgment of the case and can provide evidence support for the court. The identification results may also influence the formulation of industry norms and standards and promote the healthy development of the industry.

Zhongke Testing is a product quality appraisal service organization registered with the court. It can provide pneumatic hammer quality appraisal services. It has a professional appraisal team and advanced instruments and equipment to provide fair and accurate appraisal results for pneumatic hammer quality appraisal.

pneumatic hammer quality appraisal technical methods include:

1. Appearance inspection: comprehensively inspect the appearance integrity of the equipment, measure whether the dimensions comply with the design specifications, detect surface quality (such as coating uniformity, material finish), and check whether the nameplate information (model, parameters, production identification, etc.) is complete and accurate.

2. Functional test: simulate operating conditions and apply specified pressure, conduct practical inspections on the equipment's start, run, stop, brake and other functions, and observe whether each function responds normally and operates stably.

3. Pressure test: Use professional instruments to measure the actual working pressure of the equipment, compare the obtained data with the pressure indicators required by the design, and verify whether the power system meets the design standards.

4. Noise test: When the equipment is running, the noise detection instrument is used to collect the operating noise value, and based on the environmental protection standards, it is judged whether the noise level meets the compliance requirements.

Applicant Company A signed a purchase contract with Respondent Company B for "a batch of pneumatic hammers". After receiving the goods and using them for a period of time, the Applicant discovered that some of the pneumatic hammers manufactured by the Respondent were damaged. Company A believed that the pneumatic hammer had quality problems and required Company B to compensate for the losses, while Company B claimed that the damage was caused by Company A's improper use. The two parties could not reach an agreement and went to court, which entrusted a third-party appraisal agency to conduct appraisal.

Identification analysis results:

The quality analysis expert group discussed and comprehensively analyzed the relevant information of the "Pneumatic Hammer", contract technical agreement, on-site investigation case materials and other data, and made the following quality analysis opinions:

1, the air motor blade of the pneumatic hammer involved in the case has insufficient hardness, causing scratches or fractures when running at high speed;

2, the hammer head of the pneumatic hammer involved in the case has a defective heat treatment process, and the surface hardness does not meet the HRC58-62 standard, resulting in pits and deformation on the working surface.
