JY100Z Straightening Machine

The WXC series of center-less lathe and JY series of straightening machines are high -level new equipment with independent intellectual property rights on the basis of absorbing and digesting foreign advanced technology, making adventurous innovation, and research&development take into consideration of actual situation of domestic companies. Our technology reaches the domestic advanced level in reliability and quality while keeps a relatively lower price, with its efficiency more several times than the conventional process. Our products are suitable to process different kinds of metal material, for instance, black metal material such as structural steel, alloy steel, spring steel, bearing steel,tool steel, copper and copper alloy, aluminum and aluminum alloy, magnesium alloy, titanium and titanium alloy and other non-ferrous metal materials. WXC series of centerless lathe is high-efficient specialized lathe to make a rough or fine machining to the surface of bar material such as slender shaft and other bars. It is able to not only get rid of the imperfection on the bar surface , de-carburized layer, crack etc, but also to guarantee relatively high accuracy. It is especially suitable to process extra long bar and bar with large machining allowance.

Machine Introduction

Series JY straightening and calendering machine adopted special curve between upper concave and the lower convex roller, The technology reaches the domestic advanced level in reliability and quality and its efficiency is several times more than the conventional process.Reliable performance, high quality and low price.

The products are suitable to process different kinds of metal material, for instance, ferrous material such as structural steel, alloy steel, spring steel, bearing steel,tool steel; non-ferrous metal like copper and copper alloy, aluminum and aluminum alloy, magnesium alloy, titanium and titanium alloy and other metal materials.

The machine is mainly used for the precision straightening and calendering of the metal bar after peeling or grinding. In addition, the machine can also be equipped with hydraulic protection device which used for the straightening of black bar and the straightening of precision forged round bar. Because its calendering and straightening is completed at one time, so the work efficiency is high.

Main Parameters:

model		JY100ZY
Input bar	straightening(mm)(non-drawing material)	Tensile strength σ_b≤450(Mpa)	Φ25≤d≤Φ100(2000≤L≤ ≥6000)
		Tensile strengthσb≤600(Mpa)	Φ25≤d≤Φ90(2000≤L≤ ≥6000)
	Surface hardness	≤HB320±10
	straightness(mm/m)	Black bar：≤5,whole length of 6 meters≤20mm/m
	Diameter tolerance	Black bar：h11
	Ovality tolerance	≤0.3mm(thesmaller the dia, the smaller the ovality)
	Surface roughness(Ra)	≤6.3～12.5mm
	Both ends	No hook bend,if it is there any,shall to be cut
Output bar	straightness(mm/m)	≤1mm/mtrs non-cumulative over the full length of the bar. However the above strightness shall be the measured value minus ovality ,and shall not be aplicable up to 100mm at both ends
	measurement	Feeler gauge
	Diameter tolerance	Black bar:better than input bar
	Surface roughness(Ra)	Black bar:better than input bar
Quantity of straighten roller		2
Diameter of straightening roller(mm)		Φ380
Straightening speed(CVT)		2~10(m/min)
Main motor power(kW)		75X2
Lifting motor power(kW)		4
Outline dimension(m)(reference)		Main machine 8.1X3.1X3.6
weight(t)(reference)		Main machine 27
Total capacity(kW)(reference)		180
Compressed air source(user prepare)		0.5~0.8MPa.1.8m³/min.with 2-level oil-water separator

Note：①The hardness of raw material should be uniform,the difference of HB hardness values in the same bar material should≤±10(difference of HRC hardness values≤±1).The straightness of Input material shall meet the requirement in this agreement,otherwise automatic feeding can not be realized.Both of the material ends must be chamfered before straightened.When the material is titanium alloy,it needs to be heating straightened.Tolerance overrun and material length is too short and overrun need manual feeding;Bars with large diameter, high strength, high hardness and poor straightness need to be used at lower speed.

Note ②: Due to the difference of material performance, the head and end of the finished product has a certain length, and the straightness of the black bar material is about 1.5mm/m.
