How to carry out Single Chain Drawbench parts of the inspection
Single chain drawing machine is mainly used for shafting products in the heat treatment, transportation and rolling, drawing and other molding process after the bending design of the finishing equipment. The main principle is through the straightening roller on the bar and so on to make it to change the straightness.
Before the Single Chain Drawbench operation, we should check the main parts to prevent the operation of the mechanical failure and affect the operation process.
1, first confirm the hydraulic system is normal, check the oil and gas systems, cooling system with or without input, check the main drive conditions are met, must ensure a good running state, the various parts of the screw shall not be broken and loose phenomenon, to ensure that the cooling system is running well.
2, check the empty operation, requiring the support roller and work roll close contact, all rotation.
3, the material before straightening, should ensure that the surface and the table without foreign body.
4, check the single-stranded drawing machine work roll, before and after the roller and front and rear panels, can not scratch the steel plate of the metal, burrs and other debris, or should take immediate measures to clear.
5, sometimes also need to be based on different material thickness, adjust the single-chain pull machine roll gap.
The following is for the Single Chain Drawbench fixture design requirements of the four points:
1, space requirements: single-chain drawing function - the installation of multiple surfaces, so the fixture in the space to meet the tool may be close to all the holding surface. In addition, the fixture pallet has a movement, care, sinking and rotation and other actions, so the fixture should not have any interference with the machine.
2, fast re-adjustment requirements: CNC machining can be quickly replaced by the processing program to transform the processing object, in order to reduce the replacement tooling auxiliary time and valuable equipment waiting for idle time, in the replacement of the workpiece, the fixture requires a quick re-adjustment or replacement positioning clip Tight function of the device.
3, fixed point requirements: the workpiece should be fully positioned in the fixture, and the base of the workpiece relative to the machine tool origin should have a strict location to meet in the machine coordinate system to achieve the workpiece and tool relative movement requirements. At the same time, the fixture should be fully positioned on the machine tool. Each positioning surface on the fixture should have precise coordinate size to meet the requirements of positioning and installation in CNC machining.
4, precision requirements: As a single chain drawing machine with continuous multi-profile automatic processing features, so the requirements of single-stranded drawing machine fixture than the average machine tool fixture precision and stiffness are high, this can reduce the workpiece in the The positioning error in the fixture, the clamping error and the deformation error in the roughing.
