Main Specification
Diameter of capstan is Φ560mm and the number of capstans is 8 pieces.
Inlet diameter is Φ7mm, outlet diameter is Φ3mm.
Max drawing speed: 8m/s.
Total power: about 251KW.
Dimension18000mm(length)*2500mm(width)*2200mm(height)
Unit Performance
The unit is controlled by PLC, man-machine interface and inverter to realize skips of any capstan.
In the process of wire feed, any capstan can be operated in combination.
With the application of touch screen, as the operating panel of drawing parameters input and operation data display, it can monitor the drawing parameters and operation data of the equipment instantly.
The process has functions of automatic computing of the reduction, reaching the set weight automatically stop, wire broken stop, security protection, operation helps and fault query.
It can start at low speed, automatic acceleration to the set speed.
It has the function of measuring the velocity and the length. When the weight winded is close to the preset weight, the machine will automatically decelerate and stop.
Equipped with remote program updates and fault diagnosis functions.
Equipment Introduction
Pay off machine
Outside diameter of bobbin in the spooling machine: Φ800mm. We can also design according to customer requirements.
Mechanical permanent damping release, manual adjustment of release tension, simple structure and convenient maintenance.
Clamping bobbin by cylinder and there is a check valve to avoid the bobbin coming off when the air pressure suddenly reduced.
Drawing machine
The foot switch, the control buttons and the separated operating panel is equipped at each block to achieve simple and convenient operation
Each block has a separate pressure regulating valve to ensure the tension can be adjusted and stability.
The motor is equipped with brake disc. which can be controlled by the computer to ensure the machine to stop accurately, quickly and steadily.
The working surface of the wire drawing drum is sprayed with tungsten carbide, and the surface is mirror polished with a hardness of HRC ≥ 60.
It is not only hard and wear-resistant, but also does not damage the surface of the welding wire.
The inside of capstan is directly water-cooled with copper pipes.
The inner surface of the capstan is treated with hot spray zinc to effectively prevent scaling and prolong maintenance and cleaning cycles.
The shaft of capstan adopts human centered (C&U) bearings.
The lower oil hole is led out to the outside, making it convenient to add grease and effectively extending the service life of the bearings.
The drawing die box is divided into two parts: cooling and lubrication.
The mold cooling adopts indirect water cooling; Lubrication adopts oil lubrication, manually adding lubricating oil and reserving oil drain port.
The arrangement of the upper and lower pipes for the cooling water of the drum and mold box is reasonable, making maintenance convenient.
Each block is equipped with some control buttons, such as Single/Multi, JOG forward/JOG back, Start, Stop and so on.
The last capstan of the machine has a wire tension mechanism, and the tension comes from the cylinder. Tensioning wheel diameter Φ 500mm, made of nylon.
The tuning roller balance adopts a cylinder, and the detection adopts a non-contact displacement sensor.
1 # -6 # adopts a reducer and narrow V-belt transmission, and #7-#8 adopts a two-stage narrow V-belt transmission.
The belt adopts SPA/SPB narrow V-belt, which has high transmission efficiency and long service life.
Motor Power: #1-#8 all 30kw AC Motor.
Take-up Machine
Outside diameter of bobbin in the take up machine can be designed according to customer requirements.
Constant tension while winding, equipped with tension sensor set in the dancer to maintain the constant winding tension.
Bobbin clamping by cylinder, and have a check valve to avoid the bobbin is falling off when the air pressure suddenly reduced.
Wire arrangement is driven by an independent motor to drive the timing belt to adjust spacing of wire easily and prevent the surface of wire from scratch by friction.
Motor Power: 11KW AC motor.
Safety Protection
The whole machine will brake and stop immediately if the wire is broken.
Every capstan respectively has shield switch. When the machine is running, if open the shield, the machine will deceleration and stop. While if the switch of ‘Ignore wire breakage’ is on, it has no such function.
Functions above referred can be manually turned off from touch screen for easy wire feeding.
The front of the machine is equipped with a rope emergency stop device.
Emergency stop buttons are installed on the control panel, wire release rack, and wire collection machine to facilitate quick parking in emergency situations.
Automatic alarm when the air pressure is insufficient.
