Automatic stamping connection by press and automation system, complete the work of the workpiece stamping presses, stamping automation system to complete the material piece unstacking, automatic transmission line, tail discharging work, usually contain unstacking system, automatic transmission system and tail discharging system.
Composition frame of punching automatic line
At present, the domestic stamping line is mainly based on the manual line, and the line is facing the following problems:
Multi layout, single operation, manual transmission, low production efficiency;
There are many man-made factors, and the bad products are high;
High energy consumption and high production cost;
The stamping site management complex, prone to accidents;
The labor cost is increasing year by year.
Based on the above problems, the automatic stamping line has become the inevitable trend of replacing the manual line:
The stamping production line is divided into multi machine line stamping production line and multi station press production line.
1, multi machine line stamping production line
Is the machine arranged side-by-side together, press between the manipulator or robot reclaimer, feeding, the production line can be configured according to the requirements of both single and double station wagon, robot baiting.
The common multi - wire connection stamping manipulator is divided into four categories:
A structure: rail type manipulator, under the direction of movement about both servo motor drive; the left and right transmission drive shaft driven by a servo gear motor, drive rod (special aluminum material), in order to achieve the purpose of transferring about; upper and lower transmission driven by servo drive shaft turbine reducer shaft operation special. In order to achieve the lifting; suction arm is fixed on the cross bar, by vacuum suction or electromagnet or pneumatic gripper, the main choice is the product according to the work.
B features: due to the limitation of the bar material, so that the arm grab single product weight, basically each arm maximum load is 5Kg, if the machine line over 10 presses above, each arm maximum load is less than 3Kg. This manipulator has the advantages of low cost, and with the open pressure unit production line, the whole line of low cost, because the rail rigidity limit line span is not too long, and the speed is not too fast, the transmission efficiency in general 6~12 / min, suitable for open single and double machine lighter workpiece (small). Transfer.
Independent mechanical hand
A structure: independent mechanical hand, driving up and down both the left and right transmission servo motor; the servo motor drives the synchronous belt, the synchronous belt is fixed at both ends of the section, so when the synchronous belt, then the profile followed the movement, which is fixed on the profile arm is in motion, so as to achieve about the purpose of transfer; up and down is driving the servo motor drives the turbine speed reducer and the auxiliary connecting rod special to arm.
B features: the manipulator support structure is mainly C type structure, so it absorbs the monolithic material piece a maximum weight of not more than 10KG, and each section is fixed with two arms, so a single section bearing no more than 20KG; the middle position is a transitional positioning device, to guarantee the precision and transferred to the auxiliary intermediate station the. The mechanical hand is suitable for multi machine between large and heavy parts delivery, generally with punch for the Longmen type single and double point press, reclaimer direction basically from punch side opening position, flexible layout, stable operation, the entire line of production efficiency can reach 10~15 / min.
A structure: the current mainstream translational manipulator is five axis manipulator, the spindle and the end manipulator with rotational degrees of freedom, the axis is translational degrees of freedom, each equipment shaft adopts servo motor + reducer drive manipulator, the main body is composed of high strength aluminum with fine line type slideway, the end is equipped with the vacuum suction air or electromagnetic sucker.
B features: the original intention of the birth of the robot manipulator is to liberate the press, the essence of a machine with the work of the press on the plane, flexible layout, small footprint;
Disadvantages: poor reliability, short life, low load capacity, production efficiency is not high;
Application conditions: machine reclaimer height can be inconsistent, suitable for the transformation of the old line machine, the customer does not need to redo the mold.
C applicable condition:
4, robot arm production line
Application: for automatic stamping production line handling and palletizing.
A wide working range
According to the different stroke, the range of the arm is enlarged, and the possible range of motion of the robot is extended.
B good adaptation to environment
The joint with double seal structure and waterproof socket, the protection level of the wrist part reached IP67, the axis protection grade reaches IP65.
C high scalability
In the optional parts equipped with built-in valve and cable detection. A variety of peripherals to achieve the application and handling easier. In each arm of the shaft are equipped with a mounting screw hole for cable bracket, easy additional wiring and piping.
2, single machine multi station stamping production line
Multi station stamping production line is working in a continuous stroke, instead of single mode single machine automation line, improve the production efficiency; high automation multi station press to further improve the surface quality of the workpiece, reduces the failure rate, reduce the operating personnel and the work site, helps to reduce the cost;
