Abstract
A crimping die for a small insulation cylinder adopts the scheme that a positioning bearing, a male die and a positioning bracket are fixedly mounted on a baseplate; a female die is connected and fixed with a guide rod; the guide rod is sleeved into a guide hole of the positioning bracket; a screw rod is screwed in a threaded hole of the positioning bracket; a pull threaded rod is lapped between the top end of the positioning bearing and that of the positioning bracket or is opened; and a brush coating part of a rolling carton board is clamped between the male die and the female die. The crimping die can reduce the number of manufactured dies, reduce the production cost, improve the production efficiency, and has the advantages of convenient operation, long service life and good applicability.
Description
Technical field
The utility model relates to the power transformer technical field, specifically is meant a kind of little insulating cylinder pressure welding mold, is applicable to the crimping of the little insulating cylinder of power transformer.
Background technology
Because the little insulating cylinder of φ 240-φ 400mm can not crimping on the insulating cylinder press-connection machine of routine, need make different moulds according to the size of insulating cylinder diameter and carry out crimping, traditional moulds is a cylinder, compression bonding method is: the cardboard that blanking is finished respectively mills 30-50mm at two ends slope, carry out round as a ballly then, behind round as a ball the finishing, cardboard is trapped among on the ready cylinder mold, brush PVA glue on the slope, tighten up up to adhesive curing with bandage then.Its shortcoming is: the insulating cylinder of crimping different-diameter, and needs are made the mould of different-diameter, and the die production time is longer, and the mould recycling rate of waterused is low, causes production cost higher, and the production time is long partially.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and a kind of little insulating cylinder pressure welding mold is provided, reduce the quantity of making mould, reduce production costs, enhance productivity, and easy to operate, long service life, applicability is good.
The technical solution adopted in the utility model is: be mounted with positioning support, punch, locating support on base plate, die is connected and fixed guide rod, guide rod is inserted in the guide hole of locating support, other has screw mandrel to be screwed into the silk hole of locating support, draw screw rod overlap joint between positioning support top and the locating support top or open, clamp the brush coating position of round as a ball cardboard between punch and the die.
In the technique scheme, the bearing of positioning support and locating support and base plate is welded with the reinforcement set square.
In the technique scheme, screw mandrel one end has Hough.
The utility model is reliable for little insulating cylinder crimping, and versatility is good, can greatly reduce the quantity of making mould, reduces production costs, enhance productivity, and also easy to operate, long service life.

Embodiment:
Referring to Fig. 1, Fig. 2, little insulating cylinder pressure welding mold of the present utility model, comprise positioning support 1, pin 2, draw screw rod 3, packing ring 4, nut 5, guide rod 6, screw mandrel 7, set square 8, Hough 9, punch connecting bolt 10, punch 11, die 12, die connecting bolt 13, locating support 14, base plate 15, earlier with positioning support 1, set square 8, punch 11, locating support 14 is welded into an integral body with base plate 15, then guide rod 6 and die 12 are welded together, and this integral body is packed in the guide hole of locating support 14 by guide rod 6, again screw mandrel is screwed in the silk hole of locating support 14, when using, earlier cardboard is pressed drawing and launched long blanking, the barefoot groove is also round as a ball then, behind round as a ball the finishing, open and draw screw rod 3, cardboard is inserted between die and the punch, brush PVA glue on the slope of cardboard, clamp the brush coating position with die and punch, shut and draw screw rod 3, tighten screw mandrel 7 again, die and punch are fitted closely, after waiting glue to do at last, will draw screw rod to open again, paper web takes out stand-by.
This mould can be fit to diameter at φ 240-φ 400mm, height is less than the crimping of all the little insulating cylinders in the 1m scope, do not need to make the mould of different-diameter according to the insulating cylinder diameter, thereby shortened whole insulating cylinder and made the production cycle that finishes from expecting down, reduce production cost, improved production efficiency.
Claims (3)
1. one kind little insulating cylinder pressure welding mold, it is characterized in that on base plate, being mounted with positioning support, punch, locating support, die is connected and fixed guide rod, guide rod is inserted in the guide hole of locating support, other has screw mandrel to be screwed into the silk hole of locating support, draw screw rod overlap joint between positioning support top and the locating support top or open, clamp the brush coating position of round as a ball cardboard between punch and the die.
2. little insulating cylinder pressure welding mold according to claim 1 is characterized in that the bearing of positioning support and locating support and base plate is welded with the reinforcement set square.
