Description

Automatic-extrusion overlay film former
Technical field
The utility model relates to a kind of overlay film former, particularly relates to a kind of automatic-extrusion overlay film former of the chip for the manufacture of self-recovering type fuse.
Background technology
Self-recovering type overcurrent protection components and parts (self-recovering type fuse) are by high molecular polymer and electric conductor composite molding and overlay film forms the main chip of these components and parts, and the manufacture method of this chip mainly contains the following two kinds at present: (1) shaping first as required chip size makes stainless steel frame and upper and lower corrosion resistant plate; Lower corrosion resistant plate to be lain on work top and stainless steel frame is kept flat in the above; Then in stainless steel frame tiling on one with the upper film (be generally Copper Foil) of stainless steel frame with size; The particle of high molecular polymer and electric conductor composite molding is claimed to divide in stainless steel frame by constant weight amount; To tile again a upper lower film (being generally Copper Foil); Cover corrosion resistant plate again; The corrosion resistant plate up and down of stacking good material is carefully put on the table top of vulcanizing press stably; Set between vulcanizing press temperature 150-200 DEG C, pressure setting is at 20-25Mpa, and hot pressing time is set in 250-350 second, and the dwell time is set in 550-650 second, and process parameter reaches started by press switch after requirement, the upper and lower corrosion resistant plate of taking-up after completing; Upper and lower corrosion resistant plate is opened, takes out stainless steel frame, the chip taking-up being attached to the composite molding of stainless steel frame is lain in desktop and naturally cools; The composite remained on stainless steel frame and corrosion resistant plate is cleaned out, prepares the shaping of next chip; (2) be first set between 200-260 DEG C by each for extrusion shaping machine warm area, design extrusion screw rod rotating speed, at 10-250rpm, will adjust die openings size to the chip thickness needed; The particle of high molecular polymer and electric conductor composite molding is put upside down in the blanking tube of extrusion shaping machine; Start extrusion shaping machine; After observation composite is evenly extruded from die openings stably; Between the upper and lower pressure roller being cut into calender of the material horizontal extruded, after setting the rotating speed of upper and lower pressure roller, start calender, composite forms smooth sheet material after upper and lower pressure roller pressure; Be put on work top by smooth for corrosion resistant plate, again stainless steel frame is put on stainless steel, tile a lower film (being generally Copper Foil) in stainless steel frame, again smooth composite board good for roll extrusion is placed on the copper film in stainless steel frame, an other upper film (being generally Copper Foil) in covering, and cover corrosion resistant plate; The corrosion resistant plate completing composite is put in the table top of vacuum press; Set between temperature 150-200 DEG C, pressure setting is at 20-25Mpa, and hot pressing time is set in 250-350 second, and the dwell time is set in 550-650 second, and below vacuum 1Mpa; Process parameter reaches started by press switch after requirement, the upper and lower corrosion resistant plate of taking-up after completing; Upper and lower corrosion resistant plate is opened, takes out stainless steel frame, the chip taking-up being attached to the composite molding of stainless steel frame is lain in desktop and naturally cools; The composite remained on stainless steel frame and stainless steel is cleaned out, prepares the shaping of next chip.
