The screw thread roughness is brought up to
On, having overcome the phenomenon that cracks behind the crimping service life of having improved sealing ring, productivity effect improves more than 6 times.
Purpose of the present invention can reach by following measure:
A kind of new technology of packaging container steel bucket sealer helicoidal processing, this technology comprises that blanking draws, cut upper port cover, smoothing flange and upper end internal orifice surface chamfer, extruding crimping inner-diameter portion whose, it is characterized in that in the described extruding crimping inner-diameter portion whose technical process that flow on the crimping sidewall height the material of the required reaming internal diameter of bead portion redundance is counter, the internal diameter roughness reaches after the reaming
Make blanking draw highly and shorten, reduce blanking blank outside dimension, saved raw material; The chamfering that the wall upper-end inner diameter is drawn in utilization adds to Yin Layan to material and causes sidewall upper face outer wall fillet part, thereby guarantees that sidewall is vertical with flange; The rolling machining internal thread makes the threaded portion internal diameter narrow down to the thread size requirement.
The present invention has following advantage compared to existing technology:
1, production technology is simplified, and production efficiency improves.
(technology is that blanking draws to new technology by adopting the processing of a kind of steel bucket sealer helicoidal, cut upper end cover, smoothing flange and upper end internal orifice surface chamfer, extruding crimping inner-diameter portion whose, the rolling internal thread), now utilize the frock forcing press to produce to substitute cutting on the lathe, production efficiency improves (because the number of strokes of existing forcing press per minute kind is more than 3 times of lathe feed) more than 3 times, now utilize roller mill production to substitute the cutting of tapping machine, productivity effect improves (number of strokes of thread roller milling train is more than 4 times of tapping machine cutting) more than 4 times, and prior one side is to have avoided owing to different cutters are selected in every batch steel composition variation, the trouble that screw tap brought needs the different cutters of grinding repeatedly with operating personnel, the worry of screw tap shape.
2, improve the quality, reduce production costs.
By adopting a kind of new technology of steel bucket sealer helicoidal processing, cause original Yin Layan the roll out material of limit part wall thickness and the material that screw tap cuts of upper surface material that outer wall knuckle and flange out of plumb part car fall and car to fully utilize, make existing production material requested blank the spread material reduced 5mm, make it raw-material consumption aspect and saved 19.5%.Calculate at 5,000,000 as selling a steel bucket sealer helicoidal at present year by certain enterprise, can increase the benefit more than 600,000 yuan, simultaneously, because of adopting moulds of industrial equipment production, product size is stable, and especially the bead portion roughness is by original
On bring up to
Not having sealing ring when rubber seal and bead portion fitted seal scratches with the squeeze crack phenomenon and produces, avoided the in use tolerant leakage phenomenon of user fully, improved the service life of rubber seal, owing in the rolling threaded process flow harden effect is arranged, thereby improved the intensity of screw thread greatly, screw thread is fuller, and is better with cooperating between the plug screw screw thread.
