Detailed Description

The utility model discloses the implementation explains below combining the description drawing, in superplastic complex panel spare forming process, because equipment shuttle business turn over speed leads to the sheet material performance to receive the influence and go up the mould physiosis and form behind the die sinking forming part natural cooling drawing of patterns and drop down lower mould or table surface and cause the problem of work piece fish tail, in order to solve above problem, the utility model provides a quick pay-off pick-off mechanism, side view and plan view are shown as figure 1 figure 2, and this quick pay-off pick-off mechanism includes main support 4, last track 6, upper bracket 10, holds in the palm flitch 12, and the equipment is accomplished as shown in figure 4 assembly schematic diagram.

Lower track gyro wheel 1 is installed in main support 4 bottom through lower gyro wheel support 3, the main part mechanism is placed on the track that is on a parallel with thermoforming machine shuttle car track, go up track 6 and lean on the screw to install on main support 4 upper portion, it has spacing 8 to install at last track 6 front end and rear end, upper bracket 10 is installed on last track 6 through upper bracket connecting piece 11 and last track slider 7, the concrete structure is shown as local perspective, the location can be adjusted as required through the locating hole cooperation actual production on last track 6 to spacing around going up track 6, material supporting plate 12 is installed to upper bracket 10 front end, material supporting plate 12 coats and is stamped one deck ceramic fiber cloth, upper bracket 10 rear end is installed hanging hole 13.

In the superplastic forming process, because the working table top of the thermoforming machine is in a high-temperature state, the plate is placed on a lower die in the past, the lower platform shuttle car of the thermoforming machine needs to be driven out of a heating chamber, then the lower platform shuttle car is driven back to the heating chamber for superplastic gas bulging forming, the period of time is long, the period of time during which the heating chamber is opened can cause a large amount of heat loss, so that the internal temperature of the heating chamber is lower than the forming process temperature, the heating chamber is heated for a long time after the heating chamber is closed to increase the temperature of the heating chamber to the forming process temperature, at the moment, the plate is stored in the heating chamber for a long time in a high-temperature state, the material performance of the plate in the superplastic forming process can be greatly influenced, the workpiece can be cracked in the forming process, and meanwhile, in order to solve the problem of difficult demoulding, the upper, however, the workers in the high-temperature environment are difficult to catch the workpiece in a close range or may fall on the lower platform and the lower die to cause collision deformation and damage, the temperature of the workpiece is high at the moment, the texture is soft, and the workers can generate large deformation in the air cooling process by clamping. For solving these problems that exist in the upper die gas bulging superplastic forming process, the utility model discloses can greatly compress the pay-off and get a time and guarantee work piece forming quality. When a workpiece is sent, a plate material is placed on a material supporting plate 12, after a furnace door of a heating chamber is opened, an operator pushes a main support 4 to move forwards to the front of a lower platform, pushes an upper support 10 to extend forwards to convey a workpiece on the material supporting plate 12 to the upper side of a lower die, other operators control the workpiece to slide down to the lower die from the material supporting plate 12 and adjust the workpiece to a processing position while recovering the upper support 10 to the upper limit 8 of an upper rail 6 and continue to pull backwards through a hanging hole 13, the whole mechanism quickly moves backwards along the rail, a feeding process is quickly completed, and the furnace door is closed for later superplastic forming. When the gas expansion superplastic forming in the furnace is finished, the furnace door of the heating furnace is opened, the upper moving die of the press sliding block is opened, because the upper die is formed, the workpiece is attached to the surface of the upper die at the moment, the quick pushing mechanism is forward, the upper bracket 10 is forward extended, the material supporting plate 12 is arranged right below the workpiece, the temperature of the workpiece is reduced along with the temperature in the furnace, the workpiece is shrunk in volume, the workpiece is automatically demoulded by gravity in a short time and falls on the material supporting plate 12, the mechanism and the workpiece are quickly recovered through the hanging hole 13 again, and the closed furnace door is heated to the required temperature for carrying. The mechanism can greatly shorten the workpiece sending and taking time, ensure the processing performance of the plate, simultaneously enable the height of the retainer plate 12 to be closer to the upper die and the surface to be smooth, so that the workpiece can not generate large harmful deformation when being demoulded and being discharged from the furnace for air cooling, reduce the rejection rate, and obviously improve the production efficiency from the two aspects of reducing the production period of single workpieces and reducing the rejection rate.
