Abstract
The utility model relates to a dephospherizing unit for a plate spring mill with a variable cross-section, comprising an upper roll, a lower roll and a rear vertical roller. The utility model is characterized in that two high pressure air nozzles are arranged among the rear vertical roll, the upper roll and the lower roll of the plate spring mill with a variable cross-section; the nozzles of the central line of rolling pieces form angles of 30-90 DEG; thereby, the purposes of high efficiency dephosphorization and the avoidance of lowering the surface temperatures of rolling pieces are achieved.
Description
The utility model relates to a kind of variable cross-section milling train rolled piece dephosphorization apparatus.
At present, in producing automobile changeable section plate spring process, still do not have effective dephosphorization apparatus, can obviously influence leaf spring service life when rolling oxide skin is pressed into the rolled piece surface.For improving the anti-fatigue life of leaf spring, the employing rolling on edge (as Germany) that has, what have is to remove the rolled piece surface scale, and a dephosphorization case is installed on charging roller before rolling, make the blank that heats by the dephosphorization case earlier, to reach the purpose of removing the blank surface scale.This device not only is not suitable for rolling long awl rolled piece, and structure is huge, complicated, obviously increases equipment cost, and phosphor-removing effect is unsatisfactory, on the other hand, has accelerated the rolled piece temperature drop, has increased the operation before rolling, thereby has reduced rolling efficiency.
The purpose of this utility model provides a kind of change section flat spring mill descaling device, and it can improve phosphor-removing effect, avoids reducing the rolled piece surface temperature simultaneously.
The purpose of this utility model is real like this sight: install following two pressure-air nozzles (abbreviation nozzle) between edger roll behind the change section flat spring mill and upper and lower roll, nozzle becomes the 30-90 degree with the rolled piece center line.It is rolling that edger roll carries out side after the blank elder generation warp of heating, at this moment because metamorphosis, the oxide skin on rolled piece surface is wrinkling and loose, two pressure-air nozzles that are installed in edger roll exit, back blow away iron scale in time, rolled piece its surface scale before entering upper and lower roll is removed like this, thereby realizes the purpose of efficient dephosphorization.
The utility model is because only need to install the pressure-air nozzle between edger roll behind the variable cross-section milling train and upper and lower roll, so, can save the dephosphorization case, improve phosphor-removing effect, realize the service life of upper and lower roll and the surface quality of leaf spring, can avoid obviously reducing simultaneously the rolled piece surface temperature.
Below in conjunction with drawings and Examples utility model is specified:
The milling train dephosphorization apparatus profile that Fig. 1 the utility model proposes for basis
Fig. 2 is the work schematic diagram
This device comprises topping roll (1), bottom roll (5), back edger roll (4), top nozzle (2) and following nozzle (3), and top nozzle (2) and top nozzle (3) are installed between upper and lower roll and the back edger roll, and becomes the 30-90 degree with rolled piece leaf spring blank center line.
When the heating leaf spring blank (6) by the time by the dolly clamper deliver to the back edger roll (4), back edger roll (4) is clamped blank by hydraulic control, and it is rolling to carry out side, at this moment at back edger roll (4) and last, between bottom roll (1) and (5) because the plastic deformation effect, the oxide skin of rolled piece upper and lower surface produces wrinkling loose, utilization is installed in back edger roll (4) with last, top nozzle (2) between bottom roll (1) and (5) becomes the direction of 30-90 degree to blow away with the rolled piece center line on the oxide skin edge with following nozzle (3), and leaf spring blank (6) advances to and carries out the rolling of thickness direction between topping roll and the bottom roll.The starting of upper and lower nozzle (2) and (3) and to stop be to realize automatic switch by electric-control system by the control air-operated solenoid valve, and carry out synchronously with milling train control.
Because the pressure-air nozzle is tiltedly to blow leaf spring blank surface from the side, the iron scale on leaf spring blank surface is very easily blown off, simultaneously can not make iron scale enter the flat rolling deformed area, whole device is extremely simple, its phosphor-removing effect is very good, has guaranteed leaf spring surface quality and surface temperature.
Claims (1)
1. change section flat spring mill dephosphorization apparatus, comprise upper and lower roll (1) and (5), back edger roll (4), it is characterized in that between the back edger roll (4) of change section flat spring mill and upper and lower roll (1), (5) upper and lower two pressure-air nozzles (2) and (3) being installed, nozzle becomes the 30-90 degree with the rolled piece center line.
