finest finishing equipement for bright bar production

straighteningmachine

JY Series of straightening machine can realized precise straightening and polishing on the after peeling or grinding metal bar surface utilizing the special curves and angles between the top and bottom two rollers. It can be used in black bar material straightening as well.
There are 3 types of structure in straightening machine, two beam four column structure, prestressed structure and frame structure.The straightness can be up to 0.15——0.4mm/m , and the roughness Ra<1μm after straightening.

straightening roller:

For two-rolls straightening machine, the bending moment of raw material is realized by concave roll. Another advantage is that the angle between rolls angle and rod axis is small, whiche is 15^°. So the screw pitch of envelop line is shorter, and its straightness accuracy is higher.

Application: It could be used for bright bar , and black bar with suitable bending and surface hardness .Its straightening speed is slower than multi-rolls straightener, but its straightness accuracy is higher ,and its cost is lower.

Straightening machine:

Series JY straightening machine is mainly used forprecision straightening for the metal bar after peelingor granding and pre-straightening for the metal bar.

The machine adopted special curve between upper concave and the lower convex two straightening rolls to realize calendering and straightening at the same time,which greatly improved the working efficiency. Series JY two-rolls Straightening Machine consists of two-beams and four-columns structure,prestressed structure and frame structure.

Characteristics

1,fast feeding and straightening speed,which can reach 10-30m/min.

2,with special carves ,it can straighten and calender materials at the same time.

3,highe precision.straighteness can be 0.15-0.4mm/m,surface roughness Ra≤0.8μm.

The most vital part of a straightener is the two

straightening rollers, which desigined by our qualified engineers.The up roller is concaveand the lower one is convex,which formed a special curve to press strongly onto thematerials to realize straightening,as well as straightening.

Main Machine

The upper and lower body respectively

install a straightening roller,the upper roller is concave ,the lower roller is convex.

According to the diameter and the material properties of the bar,respectively to adjust upper and lower straightening roller angle,electric lift part adjust the gap between the two straightening rolls,start the cooling lubrication system,driven by main motor,to complete calendering and straightening at the same time. Frequency conversion stepless speed,realtime display the gap between upper roll and lower roll.Guide sleeves are installed in the inlet and outlet.Its location can be adjusted,playing guide and support role.During processing,the bar can accurately enter and leace the straightening rolls.

CHARACTER:

♦ Optimum straightening effect, even with high strength materials
♦Straightener roll from alloyed and hardened chrome steel

♦ Two-roll principle with concave upper roller and convex bottom roller to ensure that the ends are straightened

♦Lateral guidance of the bar to be straightened between the straightener rolls by special guide ledges

♦Long striaghtening roller life due to coolant lubrication

peeling machine

WXC Series Centerless Lathe(commonly known as peeling machine)is a new generation high-efficiency lathe machine which is specialized in processing of metal bar surface such as slender shaft. It can not only quickly remove defects on the surface of round steel such as decarburization layer and cracks, but also realize relatively high precision and roughness. It is especially suitable for processing of super long round steel bar, with working efficiency several times of the traditional processing technology.
This machine is mainly applied in the production of bright material and bright steel bar, and in the field of machinery manufacturing, auto parts, bearing production, spring manufacturing, military enterprises, the production and processing of slender shaft, titanium bar, copper bar, aluminum bar, magnesium bar and other non-ferrous metal bar or tube, and in the field of other machinery equipment manufacturing for material preparation.

WXC series of centerless lathe includes CNC type and semi - automatic type.Semi automatic type is operated both hydraulically and manually. For example, tool is adjusted manually, feeding and extracting are realized with hydraulic controlled clamping device, and auto material loading and unloading are finished with pneumatic and electric controlled device. Operated with ease, high in cost performance, this machine is quite suitable for small or medium enterprises which requires lower degree of automation.

Advantages compared with ordinary lathe

1.When processing over-length bar,Centerless Lathe has incomparable advantages.Ordinary lathe is good at processing short bar.But there is great restriction for processing long shaft.In theory,Centerless Lathe can process the bar of infinite length.

2.Centerless Lathe is not only processing bar,also wire rod.Including from wire rod to wire rod and from wire rod to bar that ordinary lathe can't do it.

3.Processing speed 1-12m/min,the working efficiency of Centerless Lathe is dozens of times of the ordinary lathe.

4.High precision,after peeling,tolerance of diameter reach≤IT9,surface roughness Ra≤6.3μm.But after peeling,Ra≤0.8μm.

Finished Products

Our machines has been used in the preparation procedure of the following mechanical equipments manufacturing,such as slender shaft, hydraulic pneumatic components, bearings, springs, auto parts, textile machinery, cold forging material processing, instrumentation, steel pipe, cutting tools, engineering machinery, sports equipment etc.. They can also be widely used in copper, titanium, aluminum, magnesium industry, petroleum, electric power, Bridges and other industries, for example, piston rod, optical axis, bolt, spring, gear rack, toothed bar, stainless steel bars, copper bars, titanium bars, aluminum bars, magnesium bars, bearing ring, tiebar roller pin, pin , light bars, screw, mandrel, petroleum- drill pipe, steel cable, pipe billet, etc.
