Abstract
A kind of rotary hub type straightener that is used for slender metal pipe bar total length aligning, this machine principal character are two rollers commentaries on classics hubs with the coaxial reverse rotation of rolling mould commentaries on classics hub on connect between rolling mould changes hub and citation roller.Can improve working (machining) efficiency.
Description
This invention is a kind of rotary hub type straightener that is used for slender metal pipe bar total length aligning.
Growing along with industry, requirement to metal tube bar glacing flatness also all the more improves, and the aligning of elongated tubular bar is continued to use the requirement that cross-roll straightening machine in the past can not reach straightening quality again, therefore people are seeking to adopt a kind of novel equipment for straightening to align, and this novel device is rotary hub type straightener.Existing rotary hub type straightener comprises slide block rotary hub type, parallel rollers rotary hub type, cross roll rotary hub type, rolling mould rotary hub type, and five types of two roller rotary hub types etc., wherein preceding four kinds all belong to thick straightening equipment, precision is lower; And the 5th kind of straightener belongs to smart straightening equipment, but speed is slower.Above-mentioned five kinds of rotary hub type straighteners common feature structurally is have single commentaries on classics hub, so their common drawback to be:
1. purposes is comparatively single, and thick, smart aligning is difficult to take into account;
2. pipe bar in aligning process very big with torque;
3. the one-directional rotation of changeing hub causes vibration and noise easily;
4. hole shape and roll forming adapt to inadequately to the aligning of alloy steel products.
In order to overcome above-mentioned shortcoming, this research spy designs a kind of novel straightener, the essential characteristic of this straightener is that two of employing switched in opposite change hubs, the first commentaries on classics hub is that rolling mould changes hub, finish managing the thick strong work of bar by this commentaries on classics hub, the second commentaries on classics hub is that two rollers change hub, this commentaries on classics hub is responsible for managing the strong work of essence of bar, so claim that newly-designed rotary hub type straightener is a composite rotary hub type straightener.
The agent structure of composite rotary hub type straightener as shown in drawings.Main parts size has, feeding roller 1, preceding transmission device 3, rolling mould change hub 3, rolling mould 4, two rollers commentaries on classics hub 5, spill roller 6, back transmission device 7, citation roller 8, gear drive 9, motor speed-changing device 10, change hub motor 11 etc., and 12 in the accompanying drawing is the aligning part.Cooperation between the straightener parts is such with connecting: feeding roller 1 drives with the motor deceleration device respectively with citation roller 8, the top roll of feeding roller and citation roller and lower roll are symmetrically arranged in the both sides up and down of the central axis that passes through of aligning part 12, rolling mould changes hub 3 and is turned clockwise by preceding transmission device 2 drives, be provided with four rolling moulds 4 in the rolling mould commentaries on classics hub, rolling mould changes coaxial one two roller of connecting in hub back and changes hub 5, two rollers change hub and are rotated counterclockwise under the drive of back transmission device 7, be provided with two smoothing rolls in the two rollers commentaries on classics hub, rolling mould changes hub and two rollers commentaries on classics hub drives by independent motor 11.
Use this kind straightener, the aligning process of aligning part 12 is: under the carrying secretly of feeding roller 1, aligning part 12 is fed to first to be changeed in the hub 3, by the press-bending that interlocks of 4 pairs of four rolling moulds pipe bar, carry out slightly rectifying, pipe bar after thick the rectifying enters into first to be changeed in the hub 5, is finished by the formed curve roll gap of two spill rollers in first commentaries on classics hub the essence of pipe bar is rectified, and will align part by citation roller 8 at last and pull out.
On the agent structure of straightener, the something in common of newly-designed composite rotary hub type straightener and rolling mould rotary hub type straightener in the past is all to be provided with feeding roller, citation roller and the middle commentaries on classics hub that rolling mould is housed, and difference be change connect again between hub and the citation roller on an energy change hub with two rollers that rolling mould changes the coaxial rotation of hub, it is just in time opposite that two rollers change turning to of turning to of hub and rolling mould commentaries on classics hub;
In order to improve the flattening precision of straightener, two rollers can be changeed two smoothing rolls of hub and all make concavity.Simultaneously, give, citation roller can by tradition each 4 groups be reduced to each 2 groups.
The advantage of new straightener is:
1. thick, smart aligning can be finished on an equipment, and about aligning velocity ratio two roller rotary hub type straighteners double.
2. the original curved of pipe bar is not had strict restriction, the quality behind the aligning surpasses international related standards.
3. being rectified part changes can cancel each other with torque in the hubs at two, total and can eliminate the coincidence of each straightening force helical trajectory;
4. vibrate for a short time, noise is low.
The composite rotary hub type straightener of this design practices under confidential state, and what two rollers in the straightener of enforcement changeed the interior smoothing roll employing of hub is exactly one dark one shallow spill roller, concrete structure and shown in the drawings basic identical.
Claims (3)
1, a kind of rotary hub type straightener that is used for slender metal pipe bar total length aligning, this straightener is provided with feeding roller, citation roller and rolling mould changes hub, and energy and rolling mould change the two rollers commentaries on classics hub of the coaxial rotation of hub on it is characterized in that connect between rolling mould changes hub and citation roller again;
2,, it is characterized in that the rolling mould commentaries on classics hub of straightener is just in time opposite with the direction of rotation that two rollers change hub according to the said straightener of claim 1;
3, according to the said straightener of claim 1, two smoothing rolls that it is characterized in that being connected on the straightener rolling mould and change two rollers behind the hub and change hub are one dark one shallow spill roller.
