Description

Reversible stretching pad structure for press machine
Technical Field
The invention belongs to the technical field of stretching pad control, and particularly relates to a reversible stretching pad structure for a press machine.
Background
The medium and large-sized mechanical presses generally need to adopt pure gas type stretching cushions, and the application range of the presses can be expanded after the mechanical presses are provided with the stretching cushions. The stretching pad has two main functions: on one hand, the edge of the plate is compressed in the drawing process, so that the workpiece is not wrinkled in the drawing process; on the other hand, after the slide block returns, the workpiece can be ejected out of the lower die for material returning.
The common pure air type stretching cushion mounting mode is mounted on the lower bottom plane of the base, so that the foundation is required to have enough space for the stretching cushion to be mounted and maintained. If the machine tool only needs to be provided with a small-tonnage ejecting force stretching pad, the corresponding stretching pad is small in size, and if the installation mode of installing the stretching pad on the lower bottom plane of the base is still adopted, on one hand, a customer still needs to dig a foundation with enough space, so that the production cost of the customer is increased; on the other hand, in order to match the total height of the base and the requirement of a customer on the ejection stroke, the total height of the stretching pad needs to be correspondingly increased, so that the total weight of the stretching pad is invisibly increased, and the manufacturing cost of an enterprise and the purchase cost of a customer are correspondingly increased. The upward jacking motion of the general pure air type stretching cushion is realized by the air pressure of an air supply source, and the falling motion is realized by discharging the air in the stretching cushion through the descending weight of the sliding block. If the sliding block fails and cannot move downwards, the stretching pad cannot smoothly fall and return, and the gas in the stretching pad is discharged and decompressed by manual operation, so that the stretching pad falls under the self weight. Such stretching pad jack-up and fall motion do not realize full automatic intelligent control, relatively later.
