05 Shell barrel welding, threading machine process of electrostatic spraying coating line
The shell edging machine production line is a professional automatic production line for water heaters. The production line mainly consists of stacking materials → coiling → resistance straight seam welding → vertical barrel conveying → pre-rolling → rolling station → rotary side → turning head conveying → pre-spinning → rolling work Position → edging → conveyor line, horizontal barrel conveyor → inclined platform downhill connection. The equipment is connected by conveyor belts, the workpieces are transferred in one direction between the equipments, and the production process is fully automated. The whole line structure is composed of servo motor, PLC program, pneumatic component assist, man-machine interface operation, hand automatic switching mode, parameter modification, saving, and adjustment, integral line integrated program control, multi-level station connection, protection Run to achieve automated control of production.
The stacking machine mainly divides the cut palletizing sheets into the rounding machine. The sheeting method sucks the sheet with a suction cup, and at the same time, identifies and divides the sheet by the double sheet detector, and then ensures that a single sheet is fed into the reeling machine. The separating mechanism changes the traditional plane suction method, and achieves the purpose of splitting by the double sheet detection and the double-sided stretching method.
The reeling machine adopts a high-speed feeding platform and a high-speed sheet material to reel, and can continuously form a coil at a high speed, and the cylinder is quickly pushed into a straight seam resistance welding machine for welding.
3. Resistance straight sewing machine
4. Stand Bucket
The workpiece exits the seam welding and passes through the conveyor belt through the vertical drum device to erect the bucket and then enters the next process. The vertical barrel adopts a geared motor to drive the cross rotation, and the horizontal barrel body is changed into a standing type, which is advantageous for the barrel movement and the vertical rotation method.
5. Resist Bucket
The position of the can is determined according to the size of the barrel and the diameter, but the position of the bucket should be simply adjusted. The bucket utilizes a cylinder to simply block the bucket and separate the barrel that is continuously abutting.
According to the barrel body and the size of the diameter, the position is manually adjusted. The workpiece is moved to the bucket station by the bucket hand device. After the bucket is swollen, the main body starts to rotate, and then the roller is pressed down to the predetermined position to return to the position, and the host stops, then The body is reset and the bucket is reset. The whole movement is realized by the servo system to realize the barrel change, the barrel and the pre-scrolling; the cylinder is clamped and the top expansion mold is used to achieve the integrated barrel pre-rolling. The control part is divided into manual and automatic control programs, touch screen parameterized input and adjustment and saving.
According to the barrel body and the diameter, the position is manually adjusted. The workpiece is moved to the canning station by the can holder. After the material is swollen, the main body starts to rotate, and then the inner and outer rollers are pressed and formed, the roller is opened and stopped, and then the body is reset. The material is reset. The roller drive is precisely controlled by a servo plus precision reducer to accommodate different material adjustments. The control part is divided into manual and automatic control programs, touch screen parameterized input and adjustment and saving.
The bucket is controlled by servo motor, gear, rack drive, linear bearing, guide post positioning, and the principle of rotation when the tray is working. PLC program control, precise bucket positioning, precise control and random adjustment for control roll forming, and preservation of various specifications of product parameters.
The center of the turning head is adjusted according to the height of the barrel body, and the height adjustment is controlled by a manual button to control the motor, and the barrel body is conveyed to the heading block magnetic block by the conveyor belt, and is rotated by 180 degrees after induction, and automatically demagnetized.
It is made of aluminum profile, plastic steel and polyurethane. The cylinder is operated and the barrel is manually adjusted. The back and forth movement adopts servo gear transmission to the ball screw and linear bearing movement, which is light and flexible.
