Quick automatic punching equipment for sealing member processing
Technical Field
The invention relates to the field of flange gasket punching equipment, in particular to quick automatic punching equipment for processing sealing elements.
Background
The flange gasket is an elastic/rigid element clamped between two flange sealing surfaces when a pipeline and equipment are in flange connection, and common types include soft gaskets such as rubber gaskets (nitrile rubber and fluororubber), asbestos gaskets (phase-out) and graphite composite gaskets, semi-metal gaskets such as metal cladding gaskets (metal shell and nonmetal core material) and corrugated composite gaskets, and metal gaskets such as copper gaskets, stainless steel gaskets and lens gaskets (suitable for high-pressure and high-temperature working conditions such as chemical and power equipment).
The soft gasket is mainly formed by compression molding, a pretreated blank is placed into a custom mold (the mold cavity is consistent with the shape of a finished gasket product), pressure (5-20 MPa) is applied by a hydraulic press, meanwhile, the temperature (such as a rubber pad needs to be heated and vulcanized, and the temperature is 150-200 ℃) is controlled, so that the blank is attached to the mold to be formed, a main body sealing surface of the gasket is formed, after the gasket main body is formed, bolt holes (namely 'punching') are processed by special equipment according to parameters of flange bolt holes, so that the bolts can penetrate through the gasket fixing flange, and common punching equipment comprises a manual punching machine (a manual rocker, a punch and a positioning tool);
For some manual punching machines/small-batch semiautomatic devices, a worker usually manually places a gasket blank on a positioning tool of the punching machine (the tool is provided with a concave tool groove which is matched with an inner hole/an outer circle of the gasket to ensure that the center of the blank is aligned with the center of a punch), then lightly presses the gasket manually/by using a pressing disc (the soft gasket needs to control pressure, deformation is avoided, a metal gasket can be slightly hard to prevent displacement during punching), manually pulls a rocker or starts the device during punching, completes punching of one hole (a part of semiautomatic devices can simultaneously punch a plurality of holes), rotates the gasket (the angle is equally divided by the number of bolt holes through the indexing disc of the tool, for example, every 90 degrees is rotated for 4 holes), repeatedly completes the processing of all holes, and finally manually takes the punched gasket out of the concave tool groove by the worker.
The positioning fixture is a core component of a positioning gasket blank and is used for ensuring the punching precision of the blank, the soft gasket is required to control pressure when being fixed, deformation is avoided, therefore, the positioning fixture of the soft gasket is usually a groove fixture (a metal gasket can be clamped by the positioning fixture), when the concave positioning fixture is used, a worker needs to correct the blank while placing the blank, the blank can be perfectly embedded into a fixture groove, if the blank is placed unevenly to cause punching deviation, after the blank is punched, the worker still manually takes out the gasket from the concave fixture groove, the fixture groove is usually provided with a through hole larger than the center hole of the gasket, namely the center hole of the gasket is often smaller than the through hole of the fixture groove, the edge of the center hole of the gasket is a protruding part compared with the through hole of the fixture groove, and the worker can take out the gasket through buckling the protruding part.
