Description

A kind of tuber

Technical field

The utility model relates to the equipment of producing electrothermal tube, mainly is a kind of tuber.

Background technology

Tuber ubiquity automaticity in the market is low, operation is inconvenient, problems such as fault rate is high, production efficiency is low, tubulation quality instability.Each roll of traditional tuber adopts a motor to realize by gear drive, though this driving mechanism also can satisfy the tubulation requirement.But during to the tubing of different-diameter, wall thickness, because of the difference of the extruding elongation property of material in the tubulation process, and speed of welding is also different.Because each king roller can not be adjusted rotating speed separately, thereby quality instability.Traditional cutting knife technology is the vertical cutting knife method that adopts cylinder to be used as power, and topmost shortcoming is the otch out-of-flatness, and depression is arranged.In the tubing use, must the excision of mouth of pipe section both have been wasted tubing, and increased the workload of pipe cutting mouth, in batch process, caused very big waste.

Summary of the invention

The utility model will solve above-mentioned existing shortcoming, and a kind of tuber is provided, and this equipment has characteristics such as rational in infrastructure, easy to operate, that production efficiency is high, automaticity is high, quality of item is stable.

The utility model solves the technical scheme that its technical problem adopts: this tuber, mainly comprise lathe bed, on lathe bed, be provided with leveling frame, several roller framves, concora crush wheel, weld assembly, coalignment and cooling package successively from being fed to discharging, each roller frame adopts drive, and promptly each lower roll wheel shaft all is connected with adjustable frequency motor by elastic coupling, reductor; The top roll wheel shaft is installed in roller frame bearing block, is between roller frame bearing block and adjustment screw, the adjustment disk and can regulates fit structure.

Also be provided with edger roll seat and electric appliance box assembly on the described lathe bed.

Position before the described coalignment is provided with horizontal metroscope.

The effect that the utility model is useful is: 1, adopt alternating-current variable frequency motor stepless speed regulation, and drive, each road roll makes pipe fitting to be processed have forward rational tractive force and hauling speed all the time in the tubulation process, improves the product quality of pipe fitting.2, compare with existing tuber, production efficiency improves more than 1.5 times, and maximum tubulation speed reaches 13m/min.Overcome tubulation quality instability and comprise the phenomenon of leaking weldering, undercut etc., to improve the quality of products.3, adopt horizontal metroscope, blanking length precision reaches ± 5mm, and realizes that chipless cuts off.4, improve the automaticity of tuber.With multiple working procedure collection such as the cleaning of stainless steel band material, smoothing, roll-in, tubulation, pipe seam welding, school circle, alignment, automatic cut-to-length, cut-outs is one, the drawback that operation is disperseed before overcoming, thus improved automaticity.

Description of reference numerals: lathe bed 1, adjustable frequency motor 2, leveling frame 3, roller frame 4, concora crush wheel 5, edger roll seat 6, weld assembly 7, gun rack 8, coalignment 9, cooling package 10, horizontal metroscope 11, electric appliance box assembly 12, reductor 13, adjustment screw 14, adjustment disk 15, roller frame bearing block 16, top roll wheel shaft 17, running roller 18, lower roll wheel shaft 19, roller frame base 20, work top 21, elastic coupling 22.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As shown in Figure 1, 2, this tuber, mainly comprise lathe bed 1, on lathe bed 1, be provided with leveling frame 3, several roller framves 4, concora crush wheel 5, weld assembly 7, coalignment 9, cooling package 10, edger roll seat 6 and electric appliance box assembly 12 successively from being fed to discharging, position before the coalignment 9 is provided with horizontal metroscope 11, and weld assembly 7 is provided with gun rack 8.Each roller frame 4 adopts drive, and can adjust separately, keeps in repair and change.Thereby Products Quality and efficiency of equipment have been improved.Each roller frame 4 is installed on the roller frame base 20, and fixedlys connected with work top 21 by securing member.Each lower roll wheel shaft 19 all is connected with adjustable frequency motor 2 by elastic coupling 22, reductor 13; Top roll wheel shaft 17 is installed on the roller frame bearing block 16, and running roller 18[is installed on top roll wheel shaft 17 and the lower roll wheel shaft 19, is between roller frame bearing block 16 and adjustment screw 14, the adjustment disk 15 and can regulates fit structure, puts according to welded tube center line fine setting roller chord position during assembling.

The utility model adopts each king roller drive, changes the alternating-current variable frequency motor speed governing into by DC motor speed-regulating, and all installations separately of each road roller frame, and this measure has obtained good effect.Each running roller can be realized independent speed governing, at different diameters, wall thickness, during the pipe fitting of material, adjust the rotating speed of each running roller respectively, make each road roll in the tubulation process, make pipe fitting to be processed have forward rational tractive force and hauling speed all the time, thereby make the tubulation quality more stable.After each roller frame is installed separately simultaneously, bring great convenience for the maintenance of changing running roller and equipment.

Home roll wheel of the present utility model adopts simulation streamline forming characteristic to design and make, thereby has improved the quality and the welding quality that are shaped.In the design of roller set, effectively utilized this characteristic.Pipe fitting carries out rolling formation with after the stainless steel band material is in smoothing, school by elementary running roller, is configured as circle by secondary running roller again, is cydariform at the soldered place and protrudes, so that welding is carried out school circle and alignment by school circle running roller at last.

The utility model adopts the rotary cutter technology, replaces common vertical-type cutting knife, and it is to adopt the driven by motor blade to be rotated squash type to cut off, make smooth, the smooth nothing depression of pipe fitting end face, improved the kerf quality of product, and realize that chipless cuts off, reduce raw-material consumption, reduce cost.

For controlling blanking length better, the utility model increases newly has installed automatic horizontal metroscope mechanism.Because of concrete use occasion difference, require to have the tubing of different length specification, we have designed horizontal metroscope 11 in the tubulation apparatus, adopt digital encoder to count control, and blanking length can be set, and precision can reach ± 5mm.Thereby improved automaticity, saved tubing, reduced production costs.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
