Abstract

The utility model provides a roller used for manufacturing a flux-cored wire with the diameter bigger than 2.0. The roller used for manufacturing the flux-cored wire with the diameter bigger than 2.0 comprises eight groups of rollers, wherein each group of rollers of the eight groups of rollers comprises two rollers arranged in an opposite up-and-down mode, an upper roller and a lower roller of the each group of rollers are provided with a matching grinding hole, the grinding hole is formed by a groove arranged on each of the lower roller of the each group of rollers and a protrusion arranged on each of the upper roller of the each group of rollers matched with the groove, a radian of the groove and a radian of the protrusion are arranged sequentially smaller from a first group of rollers and an eight group of rollers, the protrusions of the upper rollers of the front four groups of rollers protrude downwards, the protrusions of the upper rollers of the back four groups of rollers protrude upwards, and the protrusion of the upper roller of a fifth group of rollers is in a M shape. The roller used for manufacturing the flux-cored wire with the diameter bigger than 2.0 has the advantages that due to the fact that the cross-section shape of the outer surface steel band of the flux-cored wire grinded by the eight groups of rollers is complex, melting speed of the improved outer surface steel band and powder is slow, and thus the performance and the quality of the flux-cored wire are improved. The roller used for manufacturing the flux-cored wire with the diameter bigger than 2.0 comprises eight groups of rollers has the advantages of simple structure, high working efficiency, cost saving and the like.

Description

A kind of roll for the production of diameter 2.0 above flux-cored wires

Technical field

The utility model belongs to flux-cored wire milling equipment field, especially relates to a kind of roll for the production of diameter 2.0 above flux-cored wires.

Background technology

In flux-cored wire is produced; roll is the critical piece of flux-cored wire crust steel band brake forming; the main outer skin steel band of electric current of flux-cored wire welding conducts; because the cross sectional shape of at present domestic manufacturer's production flux-cored wire mostly is as shown in Figure 1 the docking of " o " shape or the overlap joint of " o " shape as shown in Figure 2; cross sectional shape is simple; fast than medicinal powder fusing of crust steel band when causing welding; weakened the Combined Protection of slag-gas to motlten metal; cause easily the weld metal slag inclusion, reduced the Performance and quality of flux-cored wire.

Summary of the invention

Problem to be solved in the utility model provides a kind of crust steel band of flux-cored wire can being bent to

Shape is improved the thawing speed difference of crust steel band and medicinal powder, improves a kind of roll for the production of diameter 2.0 above flux-cored wires of flux-cored wire performance, quality, especially is fit to the roll of the crust steel band of production complex section shape flux-cored wire.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of roll for the production of diameter 2.0 above flux-cored wires, comprise eight groups of rolls, and every group of roll comprises upper and lower two rolls staggered relatively; The topping roll of every group of roll and bottom roll are provided with the hole of rolling of matching; The described hole of rolling is equipped with the projection that matches with described groove for the bottom roll at every group of roll is equipped with groove on the topping roll, the radian of the described groove of eight groups of rolls of first group of roll to the and projection all diminishes in turn; The projection of the topping roll of front four groups of rolls is to lower convexity, and the projection of the topping roll of rear four groups of rolls is for raising up, and the projection of the topping roll of the 5th group of roll is M shape.

Match with the cross section of the crust steel belt molding of flux-cored wire in the described hole of rolling.

The final cross sectional shape of described crust steel band by eight groups of rolls by rolling progressively roller-compaction of hole.

Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, because the cross sectional shape of the crust steel band of the flux-cored wire that employing eight groups of rolls of the present utility model roll out is complicated, so improve the thawing speed difference of crust steel band and medicinal powder, improved the Performance and quality of flux-cored wire; Have the advantages such as simple in structure, high efficiency, saving cost.

The specific embodiment

As shown in Figure 4, a kind of roll for the production of diameter 2.0 above flux-cored wires of the utility model comprises eight groups of rolls, and every group of roll comprises upper and lower two rolls staggered relatively; The topping roll 1 of every group of roll and bottom roll 2 are provided with the hole of rolling of matching; The described hole of rolling is equipped with 4, the first groups of rolls 5 of projection to the described groove 3 of the 8th group of roll 12 and the radian of projection 4 that matches with described groove 3 and all diminishes in turn for the bottom roll 2 at every group of roll is equipped with groove 3 on the topping roll 1; The projection 4 of the topping roll 1 of front four groups of rolls is to lower convexity, and the projection 4 of the topping roll 1 of rear four groups of rolls is for raising up, and the projection 4 of the topping roll 1 of the 5th group of roll 9 is M shape.

Match with the cross section of crust steel band 13 moulding of flux-cored wire in the described hole of rolling.

The final cross sectional shape of described crust steel band 13 by eight groups of rolls by rolling progressively roller-compaction of hole.

The course of work of this example: utilize eight groups of rolls of the present utility model to roll crust steel band 13, as shown in Figure 3, be crust steel band 13 cross section shaping schematic views.

More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
