1,Application Instruction
GS-100 high speed thread rolling machine is a kind of high efficiency thread processing equipment which successfully produced by our factory on the basis of widely absorbing domestic and abroad advantages,and under the help of Mechanical Science Research Institute of the Ministry of machinery and electronics industry,and go through many years research. The machine is equipped with many kinds of special mold which could produce many kinds of special-shaped nails,especially used for anti loose screw shank nail ,ring nail and some new style nail. Meanwhile our factory still work on develop various standard special-use mold , more widely use.
GS-100 high speed thread rolling machine is fourth successfully generation new type machine of our factory ,it apply unit feeding, section plate slide, timing feeder and Dynamic, static, touch combination. Compare with traditional thread rolling machine, this machine has high production efficiency ( around 5-10 times than the traditional one), simple structure, convenient and reliable operation,it's a equipment suitable for various diameter,length and screw,ring shank producing
2,Basic structure and working principle
The machine is composed of single vibration type feeding system, rolling forming system, timing feeder systems and electrical control system (Details see attachment)
Electromagnetic vibration hopper is a new type of high speed feed system,The loose nail finish arrangement in the hopper and fed into rail,Then it was sent to the rolling and forming system for processing by feeder, When the blanks supply and demand imbalance,the approach ,time delay circulate line automatic controller action,and stop feeding.The rolling forming system consist of movable mold ,Static mold and timing feeder . the blanks filling from feeder. ,And continuous filling to the mold at a certain speed ,The workpiece complete thread processing between the movable mold and static mold working .
Power drive worm gear reducer and main shaft through Variable frequency speed regulating motors ,main shaft drive movable mold octagonal wheel as rotary motion. It has advantages of high transmission rate ,low noise,stability transmission ,compact structure and so on .
GS-100 type high speed thread rolling machine has the advantages of compact structure, convenient installation, high degree of automation and so on

4,Machine's debugging and operation
1,After the machine installing and positioned ,turn on electricity and check all electrical system
2,Check the main drive system, whether have friction, collision and other abnormal sound or vibration, if have problem, should stop running machine and inspect it, meanwhile remove trouble in time.
3,Adjust the gap between the electromagnet Vibrator and scale iron of vibratory hopper keep the gap between 0.6-1.00mm, to ensure the hopper can meet the normal working requirements of timing feeder
4,Adjust working stroke of hopper, rail, timing feeder, to make sure no clamping stagnation, no blocking phenomenon except broken nail.
5,Debugging of rolling die , according to the product requirements ,need to adjust the rolling die , for thread rolling system details,please check the second attachment (Diagram of Mold fitting structure ) this part consists of dynamic moldl, static mold, timing feeder etc. Before adjust the gap of the dynamic and static mold ,firstly loosen the press plate of static mold and the pressed nut(5), And then by adjustive bolt (4), tighten the bolts(4) in the same equal force, it could make the gap between static and dynamic mold smaller , until the threaded nail can reach the requirement, After adjusting the gap,make the pressure plate of static mold and nut (5) tightened , so that the static don't move during work.
On the contrary, by adjusting the bolt (4) and (5) could make the gap between the movable and static mold bigger in order to satisfied any producing requirements
If need to process long nail, could be adjusted by raising the height of rail and hopper , to expand the processing length range.
6, timing feeder system consist of the octagonal wheel , transmission fork, slider, spring pull rod, feeder working mainly by adjusting the telescopic stroke , and the feeding direction to movable mold .
7, according to different nail specifications, molds also different, Just loosen spindle nut,octagonal wheel and tapered block when replacing the dynamic mold, then you can move out the dynamic mold, but must readjust the gap of static mold and dynamic mold.
8, When replace the dynamic mold, you need to adjust tapered block,until the center of dynamic mold could get to the optimum position.
9, Adjust the magnet plate,nail pushing plate to the best position (choose the suitable nail pushing plate according to nail diameter )
5,Electrical schematic diagram
Thread roller's electrical mainly control the speed of spindle speed rolling , vibration feeding device part , require inching operation when debugging, During working, it's continuous unidirectional operation , vibration supply, electromagnet brings vibration force, meanwhile required that it could automatically stop electromagnet if feeding too much, could recover feeding when feed reduced.
According to the above requirements, It configure the controlling circuit as display in the electrical schematic diagram,read carefully when do maintenance.
6,Precautions for use and maintenance
1,Vibration hopper, the tightening bolt of the rail need frequently check its tightening condition,ensure the equipment working condition.
2,The machine use HP high temperature grease lubricating oil and number 32 machine oil, with full immersion sealing lubrication and refuel high-temperature grease to the machine's spindle once every 15 days, the main lubrication parts are Spiral worm gear speed reducer, bearing, when spindle running until 2000 hours, need to replace the machine oil.
3,During operation, You must eliminate the broken nails in the nail blanks, so as to avoid the phenomenon of stuck at work.
4,If there is a broken nail stuck in the rail, it should be removed immediately.
5,All nail cap size should be consistent. Partial cap, small cap, crack cap , nail tip hanging ears, bending nail should be removed as broken nail
6,Rolling machine adopts three-phase four wire power supply, the line voltage is 380 + 5%, when use, zero line and grounding protection line must be connected well, and keep the voltage in the allowable range. Otherwise,it may damage the electrical equipment or incur the whole machine can not work properly.
7,This machine uses the frequency conversion motor, when the machine stopped, be sure to reset the speed into zero, and then turn off the power supply, otherwise it will damage the motor.
8,Rolling machine is equipped with proximity time-delay circuit,when hopper supply feeding rail full,proximity switch act. vibrating hopper could stop feeding automatically. When slider feeding less,and could start vibrator supply automatic .
9,Before turn off the machine, you should firstly adjust the Vibration plate shake to the minimum by its switch, and then cut off the power supply ,so that to avoid a big attack to feeding hopper when open the machine next time.
10,Try inching operation as less as possible, because the fuse is easy to disconnect.
11,If met with any other major fault, please feel free contact us.
