A large number of water-cooled components are used. The upper and lower beams, the tie rods and the rollers are all cooled by internal water, and the transmission system is also protected against heat.
The pressing device consists of a frame that can be swung around a fixed axis and a hydraulic cylinder fixed at the top of the frame. The pressure is divided into two types: cold pressure and hot pressure. It has been proved that the use of oil and gas lubrication can increase the service life of the bearing by at least 5-10. Double, greatly improving the operating rate.
The characteristics of the tensioning machine (1) adopts the international advanced clamp structure, light weight, convenient to use, adjust and maintain.
(2) The main drive reducer of the tension leveler adopts a spiral bevel gear planetary reducer, adopting a new process of simultaneous cooling of the outer casing and the interior to adapt to the high temperature and dusty working environment.
(3) Three-point straightening, after the casting blank passes through the tension leveler, no surface cracks and internal cracks will occur.
(4) The German Lebes oil and gas lubrication technology was selected to reduce the failure rate of the equipment and greatly improve the service life of the bearing.
(5) The main drive system adopts vertical installation motor and heat-proof measures, which are full of new ideas, reasonable and effective.
(6) The rack layout is convenient to install, easy to repair, and accurate to the arc.
When replacing the spare parts, it is only necessary to punch the positioning pin shaft and disassemble the quick-change joint, which improves the working rate and reduces the labor intensity of the workers.
(7) The lowest point of the cooling water system is to set the drain valve and air purge, as well as the insulation and antifreeze of the cooling pipeline, further making the machine reach perfection.
The tension leveler works smoothly and reliably. The design of the tension leveler can achieve the performance of similar products imported from abroad in terms of structure and performance. It is the only domestically produced billet tension leveler to save foreign exchange for the country.
