So for can down into dishes of minimum person who cut that process allow or guarantee through accurate alignment work piece reach strict final design public errand require, alignment plane become work piece hot treated indispensable key equipment. And automatic alignment is a kind of advanced production manufacturing engineering , with the improvement of industry's whole engineering level of our country and specification requirement in recent years, this craft is more and more applied to machinery , automobile , electrical machinery , etc. in the trade widely. But our country has been depending on importing abroad all the time in the field of automatic alignment machine for a long time, there is no one's own professional manufacturer and research and develop the organization, it costs the huge foreign currency on this project every year to cause, import equipment expensive price and maintenance expenses make a lot of enterprise hope and revitalize and sigh often at the same time, have fettered the improvement of these enterprise products technological level and enlargement of the production scale seriously. Main character: measuring system of high reliability and high accuracy; self-adapting and adjusting system of correction data; concise dependent equipment of workpiece, the user can adjust the workpiece quickly; friendly interface between people and machine; necessary safety and guarding measures; more options: device to detect cracked parts via sound; automatic conveyor; up to 30-180 pieces/h. high working efficiency, the actual results are workpiece dependent. 二、The main technical specification of the ASC –II series straightene ASC –II series straightener can divide into for door type and l C type as regards form of the frame, the concrete technical specification as following form: Model Item ASC-10CM-**-Ⅱ ※ASC-10 CM-**L-Ⅱ ASC-30CM-**-Ⅱ ※ASC-30 CM-**L-Ⅱ ASC-50CM-**-Ⅱ ※ASC-50 CM-**L-Ⅱ ASC-80CM-**-Ⅱ ※ASC-80 CM-**L-Ⅱ Type of Main frame C type Outer diameter of shaft(mm) ☆φ10～φ30 ☆φ30～φ50 ☆φ40～φ70 ☆φ40～φ70 Straightened Length of shaft ≤500 ≥500 ≤500 ≥500 ≤500 ≥500 ≤500 ≥500 Number of correction point ≤3 ≤5 ≤3 ≤5 ≤3 ≤5 ≤3 ≤5 Number of measuring point ≤3 ≤5 ≤3 ≤5 ≤3 ≤5 ≤3 ≤5 Accuracy of measurement ☆±5mm Measuring way Round pole surrounding measurement slice standard gear revolution speed of workpiece 30 – 120 r.p.m Orienting way of workpiece Two center holes of workpiece or base of outer circle Controlling system CPU (mearuring unit) PLC (controlling unit) Max. loading strength 100kN 300kN 500kN 800kN Power supply Three-phase 380V 15KVA Weight of main frame 1.6T 1.8T 2.2T 2.4T 2.5T 2.8T 2.9T 3.2T Model Item ※ASC-10CM-**-Ⅱ ※ASC-20M-**-Ⅱ ※ASC-30M-**-Ⅱ ※ASC-40M-**-Ⅱ Type of Main frame door type Outer diameter of shaft(mm) ☆φ10～φ30 ☆φ20～φ40 ☆φ30～φ50 ☆φ30～φ55 Straightened Length of shaft ☆≤800 Number of correction point ≤5 Number of measuring point ≤5 Accuracy of measurement ☆±5mm Measuring way Round pole surrounding measurement slice standard gear revolution speed of workpiece 30 – 120 r.p.m Orienting way of workpiece center hole in two ends of workpiece or base of outer circle Controlling system CPU (mearuring unit) PLC (controlling unit) Max. loading strength 100kN 200kN 300kN 400kN Power supply Three-phase 380V 15KVA Weight of main frame 2.1T 2.3T 2.7T 2.8T 三、Introduction of main part Intelligent analysis measuring system, programme-controlled electrical motor, electric, the machinery , hydraulic pressure , pneumatic control system make it become the complicated technological product of more than one technological class .Its abundant and ocular man-machine interface and open technological condition to users, creating great convenience for the working efficiency of improving the complete machine, the matching organically of every main part makes the globality of the equipment can be transcendent. (一)、bearing frame Automatic straightener machine can divide into C-frame and door-frame according to frame structure form. The former is open structure, have of simple structure, easy to manufacture , rigidity bad, only fine to overlengthy shaft kind of workpiece etc. characteristic, generally used overlengthy workpiece artificial upper and lower semi-automatic straightener. The latter is closed structure, have appearance well-balanced , structure compactness , rigidity fine , little easy to be installed on automatic assembly line ,etc. characteristic, selecting the automatic upper and lower material organization for use can realize full-automatic. （二）、hydraulic pressure control system Pump stand, hydraulic pressure valve group, carry-out oil jar, hydraulic pressure control loop,etc. form the hydraulic pressure systems of straightener. Because what the key part of the hydraulic pressure system is adopted is the products of world-famous companies, such as Japanese YUKEN, Italian ATOS, Taiwan NORTHMAN,etc, have guaranteed the hydraulic pressure accuracy, stability, dependability of the work systematically. In straightener await the opportune moment when working, special energy-conservation unload design is more suitable for our country wide regional weather differences, Have guaranteed that automatic straightener can run in succession with relatively suitable temperature in any area. （三）、pneumatic control unit Pneumatic control loops including Unite one, pressure relay, valve group and air cylinder form the pneumatic unit of the straightener. It mainly control and carry out the workpiece movement of inserting urgent, localization, sorting and transport etc. In each air cylinder have position measure switch to feedback movement implementation to system, so as to control movement flow, diagnose and arrange checking in trouble. Pneumatic components mainly select the products of world-famous companies for use, such as Japan SMC, Germany FESTO and Taiwan SHAKO etc, It is reliable that the movement is sensitive , the life-span is long. （四）、runout measuring unit of workpiece The measurement amplify organization of the mechanical lever type, high accuracy displacement and angle sensor, accurate speed control motor and measurement probe form runout measuring unit of workpiece. The probe can adopt many kinds of way, such as exceed hard round pole, all-surrounding or half- surrounding measuring slice and high accuracy standard gear etc. It can measure runout in round and D shape cross-section of shaft etc. （五）、PLC PLC is key part of straighting machine. The miscellaneous and orderly movements of straighting machine are all carried out and finished under its procedure controls. PLC communicate with computer and orderly control action of part to clamp, measure, alignment position choose, pressurize to revise etc. （六）、Process system of the computer high-accuracy data collecting system, safe and reliable input and output system , integrated work station of industry with colored LCD of large screen, software package of high professional level, the human-computer interaction interface of the whole Chinese, the rich and colorful picture and text showing, the data statistics exported (can be typed) etc. formed the computer process system of the straightener. - 4 -
