blow line fixture, German blow line model, blow line price

blow line fixtures are devices used in the manufacturing process to secure workpieces in the correct position for machining or inspection, also known as jigs. Broadly speaking, any device used to quickly, conveniently, and safely install workpieces during any step of a process can be called a fixture. Fixtures typically consist of locating elements (to determine the correct position of the workpiece within the fixture), clamping devices, tool-setting guide elements (to determine the relative position of the tool and workpiece or guide the tool direction), indexing devices (enabling the workpiece to complete machining at several stations in a single setup, including rotary indexing devices and linear indexing devices), connecting elements, and fixture bodies (fixture bases). Examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures, with machine tool fixtures being the most common, often referred to simply as fixtures. When machining workpieces on machine tools, to ensure that the workpiece surface meets technical requirements such as dimensions, geometric shape, and mutual positional accuracy with other surfaces as specified in drawings, the workpiece must be properly located and securely clamped before machining.

blow line fixture types

1) Standard rectangular electromagnetic chuck Application: Surface grinding machines with rectangular tables. 2) High-power electromagnetic chuck Application: Milling machines, planers, machining centers. 3) Fine-pole electromagnetic chuck Application: Surface grinding machines with rectangular tables, milling machines. 4) Multi-function high-power electromagnetic chuck Application: Surface grinding machines with rectangular tables. 5) Rotary electromagnetic chuck Application: Various surface grinding machines. 6) Electromagnetic chuck for tool grinding Application: Tool grinding machines. 7) Circular electromagnetic chuck (concentric type) Application: Surface grinding machines with circular tables. 8) Circular electromagnetic chuck (radial pole type) Application: Surface grinding machines with circular tables. 9) Circular electromagnetic chuck (plum blossom pole type) Application: Surface grinding machines with circular tables. An electromagnetic chuck is an electromagnetic fixture that secures the workpiece using the magnetic force generated by the chuck body when the electromagnetic coil is energized. The electromagnetic chuck consists of an iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck.

blow line fixture features

Workpieces for small-batch, high-variety production account for approximately 85% of the total number of workpiece types. Modern production requires companies to frequently update their product varieties to meet market demands and competition. However, most companies are still accustomed to extensively using traditional dedicated fixtures. In factories with medium production capacity, there are typically thousands to nearly ten thousand sets of dedicated fixtures. On the other hand, in companies with high-variety production, approximately 50~80% of dedicated fixtures need to be updated every 3~4 years, while the actual wear of the fixtures is only about 10~20%. To meet the application of new machining technologies such as CNC machine tools, machining centers, group technology, and Flexible Manufacturing Systems (FMS), machine tool fixtures have the following characteristics: 1) They can quickly and conveniently equip new products for production, shortening the production preparation cycle and reducing production costs; 2) They can clamp a group of workpieces with similar characteristics; 3) They are high-precision machine tool fixtures suitable for precision machining; 4) They are new types of machine tool fixtures suitable for various modern manufacturing technologies; 5) They adopt efficient clamping devices powered by hydraulic stations and other power sources to further reduce labor intensity and improve labor productivity; 6) They improve the standardization level of machine tool fixtures. This is mainly reflected in four aspects: standardization, precision, efficiency, and flexibility.

blow line fixture selection and use

With the continuous development of China's industry, electromagnetic chucks are increasingly widely used in industrial production. The most important aspect of an electromagnetic chuck is its parameters. Among the performance parameters of electromagnetic chucks, the lifting capacity and its working class are the most critical. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight of objects allowed to be lifted under specified working conditions, also known as the rated lifting capacity. Generally, the lifting capacity of cranes equipped with electromagnetic chucks should include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting screw holes on both sides. During installation, T-shaped screws can be screwed in for lifting, and T-shaped blocks and screws are used to fix them on the workbench. Connect the DC power supply and ground wire from the machine tool, then precisely grind the upper surface of the chuck once to ensure the parallelism between the upper surface and the bottom surface. When adsorbing workpieces, sufficient positioning suction force can be obtained by bridging two adjacent magnetic poles, allowing grinding operations to proceed. Through the machine tool buttons, magnetization and demagnetization of the workpiece can be achieved.
