The usage conditions and standards of 3D flexible welding platform

The casting method of 3D flexible welding platform should be adapted to the production batch,such as sand casting.Factories that produce in large quantities should create conditions to adopt technological modeling and core making methods.The productivity of old-fashioned shock-absorbing or shock-absorbing molding machine production lines is not high enough,the labor intensity of workers is high,the noise is loud,and they are not suitable for the requirements of large-scale production.Therefore,they should be gradually transformed.For small castings,a boxless high-pressure molding machine production line with horizontal or vertical parting can be used.The production speed of solid molding is high and the footprint is small;For intermediate parts,various high-pressure molding machine production lines and air impact molding lines can be used to meet the requirements of fast and molding production lines.Core making methods can be selected,such as cold core box,hot core box,shell core,etc.For medium batch large castings,resin self hardening sand molding and core making can be considered.

Next,let's talk about the preparation work before the calibration of the 3D flexible welding platform:

1、Check if the certificates of conformity for the inspection tools and main supporting equipment are within the validity period.If they are not within the validity period,they are not allowed to be used.Contact the maintenance personnel in a timely manner to check if the inspection tools are still qualified.

2、Does the temperature at the calibration site of the 3D flexible welding platform meet the requirements of the calibration regulations(20±5℃)?If not,an air conditioner should be used to adjust the temperature at the calibration site to meet the requirements.

3、Clean the surface of the inspected 3D flexible welding platform and wipe it clean with 120#solvent gasoline.

4、The time for the 3D flexible welding platform calibration tool to balance the temperature at the calibration site should not be less than four hours.

The 3D flexible welding platform is suitable for various large workpieces,casting inspection work,and reference planes used for measurement;Used as a benchmark for mechanical inspection and measurement of machine tools;Checking the dimensional accuracy or shape deviation of parts and making tight lines is also an essential basic tool in mechanical manufacturing.Generally,a single platform can achieve the inspection,marking,and other work of normal size workpieces.However,when encountering large castings or workpieces,such as the shipbuilding industry,a single platform cannot meet the requirements of inspection,marking,and other work.In this case,several or even more than ten platforms need to be spliced together to form a larger composite platform.The splicing platform then performs inspection,marking,assembly,and other work on large castings and workpieces.

Next,let's talk about the usage conditions and standards of the 3D flexible welding platform:

1、Facilitating the loading and unloading of welded components.When operating,it should be considered that the product can be smoothly removed from the fixture after assembly positioning welding or welding,and the product should also be flipped or lifted to avoid damage.

2、The fixture should have sufficient strength and rigidity.When fixtures are put into use in production,they must withstand various forces,so fixtures should have sufficient strength and rigidity.

3、Flexibility in welding operations.Sufficient welding space should be determined when using fixtures for production,so that operators have a good view and operating environment,and the entire welding production process is in a stable working state.

4、Good craftsmanship.The designed fixtures should be easy to manufacture,install,and operate,as well as facilitate inspection,maintenance,and replacement of vulnerable parts.When designing,factors such as the existing clamping power source,lifting capacity,and installation site in the workshop should also be considered to reduce the manufacturing cost of fixtures.

5、Clamping properties.During clamping,the positioning position of the workpiece must not be damaged,and the shape and size of the product must be determined to meet the requirements of the drawing.It is not allowed for the workpiece to loosen or slip,and the constraint on the workpiece should not be too large,resulting in significant constraint stress.

The 3D flexible welding platform is the main reference tool for marking lines.Its placement should be stable,and the top should be kept horizontal.The flat surface of the 3D flexible welding platform should be evenly used to avoid local wear and indentation.Its surface should not be collided or knocked,and it should be kept clean regularly.The three-dimensional flexible welding platform is made into ribbed plate and box type.The working surface of the cast iron platform can be rectangular,square or circular,with materials HT200-300,QT400-600,ZG15-45.The working surface of the three-dimensional flexible welding platform adopts scraping and grinding technology,and can process V-shaped,T-shaped,U-shaped grooves,dovetail grooves,circular holes,long holes,etc.
