SU28095A1 - Machine for bending and immersion of spring leaves into the coolant - Google Patents

Description

The proposed rates for bending and immersing IB coolant spring leaves, equipped with a distribution mechanism consisting of an eccentric and roller pushers, have sleeves with inserts for moving dies mounted on two rotating disks-x.

In the schematic drawing, FIG. 1 shows a side view of the machine with discs in section; FIG. 2 - lap cutter machine.

The machine consists of two rotating disks J and P which freely rotate on axis 5 and carry cages 4, each of which is provided with a detachable movable 5, which serves to bend the spring sheet and bring it to quench. The mobile part of the strand; pa 5 can move in the radial direction in its guides 15, which are located in the disks 1 & 2. In order to move, serve are the clamping rollers 6, located on the fist washer 7 fixedly fixed on the axis 3. Pressing the rollers to the washer 7 is scraped by springs acting on the ends of the movable parts of the dies. The degree of curvature of the stamps is different and is made in accordance with the different curvature of the spring leaves, and the number of stamps corresponds to the numbers} of sheets in the spring. The size of the gap between the parts of the dies, and, consequently, the clamping force of the spring leaves is adjusted by the pads laid by the boat support part 8,

carrier roller 6. Instead of one roller 6, acting on the movable part of the stamp 5, you can arrange two, placing them but the ends, the stamp. In this case, two punching washers 7 should be placed on the axis 5. The entire device for arching the springs is placed in a tank 9 filled with quenching liquid and equipped with 1: conveyor 10 for finished products. By any known device, the drum and the conveyor 10 can be obtained periodically with turns in such a way that while the drum is rotated by an angle equal to the angle formed by two adjacent dies, the conveyor Yu moves by the amount of one stzpeii or one face of its leading sprocket.

In operation, each successive leaf of the spring is taken from the furnace and is inserted into the corresponding strain, which at this moment will take the last position before immersion in the liquid. With further rolling of the drum, the roller goes to the elevation of the fist washer 7 and, even before immersion in the liquid, firmly clamps the sheet in the stamp. Dale is hardened and simultaneously laying a new sheet into the next stamp, etc. When the stamp approaches the last position before it leaves the liquid, roller 6 comes off the raised fist washer and the springs retract the moving part of the stamp towards the axis of the drum. and the sheet falls on the step of the conveyor 10.

 The subject of the invention and.

Machine for HsrHCaHHa for: immersing the spring sheet in the coolant using a distribution mechanism consisting of an eccentric and pushers with rollers, differing in the use of 1-2 1-2 fixed sleeves 4-4 with guides 15-15, in which 5-5 moving dies under the action of the distribution mechanism.
