Domestic quick Single Fixtures market material problems
Fast Single Fixtures include a wide range of materials from general carbon structural steel, alloy structural steel, carbon tool steel, alloy tool steel, high speed tool steel, stainless steel, martensitic aging steel to hard alloy, insoluble alloy, , Non-ferrous metals, etc. can be used, mainly alloy steel tool steel. With the development of Single Fixtures industry in China, Single Fixtures material market, quality, variety and performance have a higher demand, Single Fixtures materials market has also been rapid development.
China's fast Single Fixtures material trial production behind the Single Fixtures industry needs, mainly in several areas:
⑴ sales channels are not smooth.
⑵, black round bar, flat steel, concentrate, pre-hardened materials and products, less standard parts. China's Single Fixtures steel market accounts for about 80% of the black round bar, the user for their own after the reorganization of the material obtained, the material utilization is low, the production cycle is long, can not meet the Single Fixtures manufacturing needs.
⑶, Single Fixtures steel general quality, high quality Single Fixtures steel, a considerable part of the requirements of high Single Fixtures steel need to go through vacuum refining and electroslag remelting, some foreign companies more than 150mm cross-section of Single Fixtures steel to ensure that the high Purity, high density, high isotropy and China's share of electroless remelted steel Single Fixtures is very small.
For the use of fast Single Fixtures know-how, have a set of methods, want to learn how to use it? The following look at the benefits of his use, and its maintenance methods.
Maintain the method of the Single Single Fixtures:
1, after use need to apply anti-rust oil to prevent rust, so you can also extend the life of the Cross Single Fixtures.
2, before the use of the limit size check whether to maintain the correct position of the single Single Fixtures, if not please adjust to the correct location.
3, if the block wear wear out of range, can be polished for repair; if the baffle, bolt, positioning cone pin wear serious and beyond the allowable error range, you can reassemble, staggered wear parts and then use to prevent errors.
Benefits of using Single Fixtures:
1. Use Single Fixtures to ensure and stabilize the machining accuracy to ensure the quality of the workpiece being machined. During the machining process, the correct use of Single Fixtures ensures that the relative position of the workpiece and the tool is properly fixed and is not affected by various subjective factors so that the machining accuracy of the workpiece can be stabilized. Here to share an article "the concept of fixture and its application areas" 2.Single Fixtures in the use of the process can shorten the auxiliary time to improve labor productivity. The use of Single Fixtures generally includes two processes: one is the Single Fixtures itself in the machine installation and adjustment, this process is mainly rely on Single Fixtures own directional keys, the tool to quickly achieve, or by looking for, Method to achieve, but the speed is slower; the second is the workpiece in the Single Fixtures in the installation process,
Quick Single Fixtures is based on the plane four-bar mechanism in the double rocker mechanism of the mechanical principle to design, the basic structure is composed of connecting rod, rack and two-bar and other four components.
When the connecting rod and the connecting rod of the two hinge joints and a series of rods and the articulation of the rack, three points in a straight line, the mechanism is in the dead position. At this time, the workpiece is pressed, no matter how much reaction (in addition to destructive reaction), can not make the pressure head to release, this is the mechanics of the dead point clamping principle.
In order to avoid in use, due to external load changes and mechanical vibration effects, the design, the middle hinge point, slightly biased in the other two hinge connection on the inside to ensure that the maximum tightening force in the case, always keep Single The Fixtures mechanism is locked in a steady state without loosening.
