How to Prevent Scratches and Deformations of Steel Sheets and Ensure Material Surface Quality During Reinforcement Steel Sheet Picking Machine Operation?

Publish Time: 2025-11-03

In the actual operation of reinforcement steel sheet picking machines, ensuring material surface quality is a crucial step in ensuring subsequent processing accuracy and finished product quality. Scratches or deformation on the steel sheet surface not only affect its appearance but may also reduce its mechanical properties and service life. Therefore, effectively preventing scratches and deformation of steel sheets during the picking process has become a key issue in production management. This article will systematically elaborate on effective measures to ensure steel sheet surface quality from four aspects: equipment design, operating procedures, material protection, and daily maintenance.

1. Optimize Equipment Design and Reduce Physical Contact

The core function of a steel sheet picking machine is to achieve efficient and accurate material sorting, but direct contact between the equipment and the steel sheet is often the main cause of scratches and deformation. Therefore, optimizing equipment design is paramount. First, non-contact or low-contact design concepts should be adopted as much as possible, such as using pneumatic or magnetic conveying devices instead of traditional mechanical clamping or roller conveying. Air cushion conveying technology can effectively reduce friction between the steel sheet and the equipment surface, avoiding scratches caused by friction. Secondly, in areas requiring physical contact, such as grippers, guide rails, and support frames, highly wear-resistant, low-friction materials should be selected, such as polyurethane, nylon, or Teflon coatings. These materials provide sufficient friction to ensure stable conveying while effectively protecting the steel plate surface. Furthermore, all edges of components in contact with the steel plate should be chamfered or rounded to prevent sharp edges from scratching the plate.

2. Standardize Operating Procedures and Control Operating Parameters

Even with a well-designed equipment, improper operation can still damage the steel plate. Therefore, establishing and strictly adhering to standardized operating procedures is crucial. Before starting the picking machine, operators should check the equipment's operating status to ensure the conveyor belt, gripping devices, and positioning system are in good working order. During steel plate loading, handle with care to avoid localized dents or edge curling caused by throwing or impact. Simultaneously, the picking machine's operating speed, gripping force, and acceleration should be appropriately set according to the steel plate's thickness, width, and material. Excessive operating speed increases inertial impact, making steel plates prone to slipping and colliding when turning or stopping; excessive clamping force may damage the steel plate surface, especially for thin materials. It is recommended to set multi-level parameter presets in the equipment control system, calling appropriate operating modes for different specifications of steel plates to achieve refined control.

3. Strengthen material protection and use isolation measures

Adding a physical isolation layer between the steel plate and the equipment is a direct and effective way to prevent scratches. Soft rubber pads or felt layers can be laid on the conveyor belt surface, which can both prevent slipping and cushion impacts. For steel plates with high surface quality requirements, such as stainless steel or coated plates, it is recommended to pre-cover the steel plate surface with a protective film or use special anti-scratch pads. In addition, during the stacking or transfer of steel plates, partitions should be inserted between each layer of steel plates to prevent interlayer friction and indentation. In the picking process, if multiple steel plates need to be processed simultaneously, ensure sufficient spacing between them to avoid collisions. For steel plates with sharp edges, special attention should be paid to their placement orientation to avoid scratching adjacent steel plates or equipment components.

4. Regular Maintenance to Ensure Equipment Accuracy

Long-term stable operation of the equipment is fundamental to ensuring the surface quality of the steel plates. Regular maintenance not only extends the equipment's lifespan but also allows for the timely detection of potential problems, preventing material damage caused by equipment malfunctions. A comprehensive equipment inspection system should be established, regularly checking the flatness of the conveyor belt, the rotational flexibility of the rollers, the synchronization of the clamping device, and the sensitivity of the sensors. If roller wear, conveyor belt misalignment, or loose clamping mechanisms are found, the machine should be stopped immediately for repair. Simultaneously, the equipment should be kept clean, promptly removing metal shavings, dust, and oil stains from the conveying path. These debris, if trapped between the steel plate and the equipment, can easily cause scratches. Furthermore, it is recommended to regularly calibrate the equipment to ensure coordinated operation of all actuators, preventing steel plate twisting or deformation due to misalignment or asynchrony.

Scratches and deformations during the reinforcement steel sheet picking machine process require a coordinated approach from four dimensions: equipment, operation, materials, and maintenance. Through scientific design, standardized operation, effective protection, and meticulous maintenance, the surface quality of steel plates can be significantly improved, the scrap rate reduced, and production efficiency and product competitiveness enhanced.
