Description

The pre-descaling device of a kind of Mechanical Crushing

Technical field

The utility model belongs to hot-rolled steel section technical field, and particularly, the utility model relates to the pre-descaling device of a kind of Mechanical Crushing.

Background technology

At present, along with the development of domestic steel building industry, shaped steel is progressively becoming one of important former material of this field steel.But due to the complexity in shaped steel cross section, finished surface is second-rate, and especially, after shot-peening or sandblast, its surface often exists pit or pockmark problem in various degree, must after necessary repairing, just can spray paint, otherwise can have a strong impact on the aesthetic property of integrated steel-structure.For improving shaped steel surface quality, common way is improve the de-scaling water pressure of a high pressure water descaling device, the water yield or increase secondary descaling steel device, but this class methods equipment investment is huge, and can significantly increase de-scaling water consumption, be the larger load of production line water treatment increase.

Utility model content

The purpose of this utility model is, provides a kind of Mechanical Crushing pre-descaling device, and that this device has is simple in structure, equipment investment is little, without auxiliary equipment, the feature such as stable, is particularly suitable for the production line that place, workshop is little, water treatment capacity has reached the upper limit.

For achieving the above object, the technical solution adopted in the utility model is as follows:

The pre-descaling device of a kind of Mechanical Crushing, described device comprises outer cover 4 and is arranged at the some de-scaling parts in outer cover 4, in the middle of described some de-scaling parts are trapped among strand 5; Described arbitrary de-scaling parts comprise backstay 3 and several S shape mechanical arms 1, and the two ends of described backstay 3 are fixed on outer cover 4; On described arbitrary S shape mechanical arm 1, through hole 6 is set, the interior activity of described through hole 6 wears backstay 3; On described arbitrary S shape mechanical arm 1, extensible member 2 is also set, S shape mechanical arm 1 is fixed in described extensible member 2 one end, and the other end is fixed on the inwall of outer cover 4.

Preferably, the quantity of described de-scaling parts is four.Those skilled in the art can also select the de-scaling parts of other quantity as required, such as six etc.

Preferably, described arbitrary de-scaling parts comprise three S shape mechanical arms 1.Those skilled in the art can also select the S shape mechanical arm of other quantity as required, such as four, five etc.

Preferably, in the bending of described S shape mechanical arm 1, angle θ is 100～160 °.

Preferably, the thickness of described S shape mechanical arm 1 is 20～40mm.

Preferably, the making material of described S shape mechanical arm 1 is cast iron.Those skilled in the art can also select other softer metal materials as required.

Preferably, described extensible member 2 is spring.Those skilled in the art can also select other forms of extensible member as required.

Preferably, described outer cover 4 be shaped as square box.Those skilled in the art can also select the outer cover of other shapes as required.

The utility model drives backstay to make axis and rotate separately by driving mechanism, and then drives S shape mechanical arm to beat casting billet surface, thereby the raw iron scale of the stove of broken casting billet surface can effectively solve the problem that high-pressure water descaling is difficult to remove the raw iron scale of stove.Meanwhile, the S shape mechanical arm contacting with strand adopts the softer metal materials such as cast iron to make, and has avoided the scuffing problem to strand in Mechanical Crushing process.

The utility model can be arranged on before a water under high pressure treating apparatus, the raw iron scale of the stove of broken strand mechanically, can effectively improve high pressure water descaling device removing effect to oxidized iron sheets on surface of casting blank, lay the foundation for follow-up finished surface quality improves.

The beneficial effects of the utility model are:

1. the utility model is simple in structure, and the difficulty of processing of device own is low, does not need the equipment such as newly-increased high-pressure hydraulic pump, motor simultaneously, has advantages of small investment.

2. the utility model is frame for movement, does not need relevant auxiliary equipment, has stablely, changes advantage easily.

3. the utility model is by beaing casting billet surface, with the raw iron scale of stove of broken casting billet surface, can effectively solve the problem that high-pressure water descaling is difficult to remove the raw iron scale of stove, can significantly improve product surface quality.
