Some tips for medical sheet metal processing:

1. In order to prevent debris damage, the transparent baffle should be installed in the appropriate position.

2. When the surface of the workpiece needs to be polished with gauze, the tool should be moved to a safe place, taking care not to let hands and clothes touch the surface of the workpiece. When polishing the inner hole, do not use fingers to hold the gauze, use a stick instead. At the same time, not too fast.

3. Do not place tools, fixtures or workpieces on lathes and spindle gearboxes. Concentrate on your thoughts while you work. No fatigue, chatting, multi-person operation, drinking and smoking.

4. Keep machine tools, tools and working environment clean and handover. When cleaning, the staff should cut off the power supply and put all kinds of material rods in a safe position.

5. When turning irregular workpieces, a counterweight should be installed and then cut.

6. The tool clamping should be firm, and the protruding part of the cutter should not exceed 1.5 times the height of the cutter body. The shape and size of the bottom gasket of the precision stainless steel sheet metal processing knife should conform to the shape and size of the knife body, and the gasket should be as little and flat as possible.

7. In addition to the automatic measuring tools installed on the lathe, the tool holder should be moved to a safe position before measuring the workpiece.

8. The saw blade and long spiral chips generated in the cutting process should be removed with the hook in time, and it is strictly prohibited to pull by hand.

9. Wear work clothes, tight cuffs and protective glasses before going to work. Female employees should wear hats. Hair caps are issued on a permanent basis. No gloves allowed.

10. The chuck should be loaded and unloaded on the spindle of the lathe, and it should be stopped to be taken out by the power of the motor. 

11. The protruding part of the fixture, dial and chicken core clip should be protected to avoid strangling clothes and other parts of the body when the sheet metal of the distribution cabinet is processed. If there is no shield, keep some distance.

12. When using the fixture workpiece, it should be noted that the center and the center hole of the spindle should be completely consistent, and the damaged or twisted can not be used. The top and middle holes should be cleaned before use, and the top of the tail seat should be firm.

13. When turning slender workpieces, in order to ensure operation safety and processing quality, the tool holder or intermediate frame should be used. Removable protective covers and safety signs should be provided outside the machined parts of the machine.

Precision sheet metal machining

How to improve the customization accuracy of medical sheet metal processing?

Errors are inevitable in the processing of medical sheet metal. To ensure efficiency, reduce material waste and labor, it is necessary to ensure and improve processing accuracy. So, what methods can improve the processing accuracy?

Original error reduction method: If there are errors in production, first find out the main factors affecting the processing error, and then try to eliminate or reduce these factors. For example, the processing of parts with shaped surfaces is mainly to reduce the shape error of the forming tool and the installation error of the tool.

 

Original error compensation method: Artificially create a new error to offset the original error in the process system. When the original error is negative, the human error is positive, otherwise it is negative, trying to make the two dimensions equal. The original error transfer method: the original error of the machining system is transferred to the direction that the machining error is not sensitive or other aspects that do not affect the machining accuracy under certain conditions. For example, when the accuracy of the machine tool can not meet the requirements of parts processing, conditions can be created on the processing or fixture, so that the geometric error of the machine tool is transferred to the aspect that does not affect the precision sheet metal processing accuracy of the chassis.

Original error equalization method: If the positioning error is large, the difference method can be used. That is, the original error is divided into n groups according to its size, and the error range of each group is reduced to the original 1/n, and then adjusted according to each group.

Original error homogenization method: For parts with high machining accuracy, homogenization method can be used. It identifies differences by comparing closely related surfaces and then modifies or benchmarks each other, thereby reducing and equalizing errors on workpiece surfaces. In machining, machining accuracy error is inevitable.

Only by analyzing the factors affecting the error, can corresponding preventive measures be taken to reduce the processing error of high-precision plate and improve the processing efficiency.

Production mode of medical sheet metal frabricating plant 2024年05月14日
Production mode of medical sheet metal processing plant Medical sheet metal frabricating operations are carried out in many areas of work, including various processing steps, such as stamping and material bending. in the process of performing these processing procedures, the operator must pay attention to whether the parameters are accurate and whether the application method meets the requirements. In addition, what exactly is the production model of large-scale sheet metal processing? Let's take a look!   Production mode of medical sheet metal frabricating: 1. The manipulator is equipped with a suction cup to suck up the steel plate and automatically identify the thickness (thickness measuring equipment with rollers). The thickness of the steel plate must meets the requirements of the procedure before it can enter the next process. 2. Put the steel plate on the CNC machine tool for hole punching and blanking, the brush on it will maintain it from being scratched, when the steel plate is moved to this position, the mold will automatically punch the hole, complete the sheet metal blanking process. The CNC machine has the function of automatically modifying and supporting the plates, which greatly improves the utilization rate of wood. 3. Move it to the automatic folding machine and bend the steel plate according to the program. After the parts are completed, the whole process of sheet metal frabrication from steel plate to finished sheet metal does not need manual control and will not cause human deviation, so that the product consistency is very good, not only the pass rate and efficiency are extremaliy high, but also the plate utilization rate is very impressive  However, it should be noted that during sheet metal processing, if the investment is to be reduced, the staff needs to complete the workflow in strict accordance with the production specifications. Therefore, before each application, we need to review the application status of the materials, and if the review is not passed, we cannot handle it casually. Six points that should be paid attention to in medical sheet metal frabrication The application of aluminum shell is also very extensive, I have to say, this is also one of the very common manufacturing processes in professional medical sheet metal frabricating customization, so what matters need to be paid attention to in medical sheet metal processing aluminum shell? Let's take a look 1. Do not use the measuring claw tip of the caliper as a marking needle, compass or other tools, do not manually shake the two PAWS or use the measuring tool as a splint; 2. Do not use oil stone and sandpaper to polish the measuring surface, measuring surface and marking part, unless it is the measurement maintenance personnel, it is prohibited to disassemble, modify and repair the measuring tool. 3. When the surface of the workpiece has burrs, the burrs must be removed before measurement, otherwise the measuring tool will be damaged and the accuracy of the measurement results will be affected; 4. Do not touch the measuring surface of the measuring tool with your hand, because the wet and cold dirt such as sweat on your hand will pollute the measuring surface and make it rusty. Do not mix the measuring tool with other tools and metal substances to prevent damage to the measuring tool; 5. The storage place of measuring tools should be kept clean, dry, free of vibration and corrosive substances, and away from places with large temperature changes or areas with magnetic fields. The measuring tools stored in the measuring box should be clean and dry, and no other debris should be stored; 6. After the measuring tool is used, clean the dirt and aluminum chips on the surface, loosen the fastening device, and apply anti-rust agent on the measuring surface when it is not used for a long time. It is recommended that full-time personnel be responsible for keeping the annual inspection records of measuring tools detected by authoritative enterprises.
