QA35-12 is a new type punching machine, punching machine series of products.
The machine has the advantages of novel design, reasonable structure, beautiful appearance, and convenient installation. Compared with similar products with low energy consumption, power efficiency of large 'processing range, etc. An ideal machine for multi - position shear punching of sheet metal.

 We went all over the world participate in the exhibitions. 
And We have customer cases in Malaysia, New Zealand, Dubai, Saudi Arabia, India etc,more than 56 countries!

Performance of machine:
This machine is suitable for punching low-carbon composition tensile strength <450MPa cold steel, angle steel, flat steel and steel plate, also can free steel and steel plate, profiled processing and punching, similar shape of non-ferrous metal products can also be for the processing - especially in machinery, electric power, construction, light industry and other factories, industry of steel material. The machine has the advantages of power consumption province, high power, small volume, light weight, compact structure, flexible operation, convenient repair and maintenance.

Technical specifications:
Stroke per minute - 30 bpm.
Electric machine - 4kw. 380V
Dimensions (mm) 1100 X 600 X 1450 (length * width * height)
Quality: 1000kg

This machine is made up of electric motor, fuselage, and transmission system, operating clutch system and working part. Motor 2 is fixed on the base seat 3. The motor belt pulley 4 is transmitted to the belt pulley 7 by the triangle belt 7. The large belt wheel 9 is connected with the helical gear shaft 1. And the helical gear shaft, the other helical gear 9 is engaged in 10, through the straight gear shaft and gear 13, and the clutch 14 will power to the eccentric shaft 12. For eccentric action of the eccentric shaft, connecting rod (on the eccentric shaft) driven movable knife seat 5 within the body to do up and down movement, is arranged on the movable knife seat is movable blade 6, blade 21 and punch 15. Corresponding - fixed blade are respectively arranged on the fuselage, knife edge 22 and a die seat 16, for moving knife holder up and down reciprocating motion, in a moving cutter plate and the fixed cutter plate between a variety of shear type village, in the upper and lower edges can shear plate and flat bar, between the punch and the die can be punched.
Eccentric axis distance is equal to 18 mm, the shear cutter stroke for 34 mm, when the eccentric shaft transferred every 30 minutes to the rotating speed of the motor, knives are with the same number of up and down reciprocating motion, i.e. per minute maximum punching number is 30.
Moving knife holder of the reciprocating motion is controlled by the clutch, step on the pedal switch 20, metal flexible shaft drives the operation rod 17 out of turn key thugs 18, turnkey in the clutch of the spring, roll out with the gear is engaged, a gear 13 drives the eccentric shaft 12, the movable knife holder to complete the up and down reciprocating motion, unclamp footswitch, the operation rod counter rotating key thugs. Convert health back to the top clutch gear and the eccentric shaft is away from the, knife seat along with stop motion.

 Machine lubrication and maintenance:
(1) maintenance of machine:
A, the machine is installed in place, should be the first wipe clean, and painted with a new lubricant, until the machine is fully lubricated, square
Can be officially opened.
B, the machine is in operation, should pay attention to the heating sleeve, bearing and motor temperature is too high, should stop using.
C, should be promptly cleaned up all the work of the tool and tool around the debris.
D, at the end of each shift, the machine must be clean, oil, to rust, long time should not remove the motor
Next, store in a dry place.
(2) lubrication of machine:
Good lubrication and correct oil, can ensure the normal operation of the machine, and can prolong its service life, so must pay attention to the lubrication of the machine. This machine all the oil cup are required to refuel, please use the lithium or calcium base lubricating oil.
A, the machine should be in accordance with the lubrication of each class 3 times, quantitative injection of qualified lubricating oil (grease).
B, lubricating oil should be stored in a closed container, often kept clean.
C, the machine is often unused, must be in the sliding rail at the lubrication oil (grease).
Installation and usage of the machine:
(1) The installation of a machine
Before using the machine to be fixed on the anchor bolt ruthenium, before installation should be according to the position shown lay the concrete foundation, do to be solid foundation, the machine is adjusted to the horizontal position and fasten: after before the test run. (shown below)
(2) Preparation for use
A.The hand turns the big belt wheel (or the flywheel), observe whether the gear meshing is correct.
B.Check the fastening parts, and the loosening of the screws tightened, check that the cover is reliable and there is no obstacle.
C.Electric circuit, motor must be in accordance with the provisions of the wiring, wire contact to be strong.
D.The lubrication of the machine must be in accordance with the lubrication requirements
E.For trial test, when found to have abnormal noise should stop immediately, check the cause and time to repair.
(3) Note in the use of machinery
A.After the machine starts, check whether the flywheel is correct, the use of the machine should be banned if it is not in the correct position.
B.Batch cutting, the use of the baffle positioning for continuous feeding.
1.A movable blade, fixed blade angle steel, round steel shear.
2.The last, the knife edge shear plate, flat and diameter less than 11 mm round.
3.The various knife and punch cannot be mixed or work at the same time.
D.Between the moving cutter plate and fixed cutter plate shear angle (round), through the height adjusting rack disk can solve the angle steel, round steel) at the incision of the horseshoe shaped.
E.After repairing the upper and lower knives, with the top wire to board flat on top and then cut, otherwise it will damage very quickly on the edge.
F.the blade clearance, punch
1.On the blade, knife edge wear or after repair, the gap on both sides of the surface should be adjusted uniformly, adjust the gap to cut 3% thick plate.
2.The special angle and angle shaped punch bottom cutter is used, the gap should be adjusted to the shear angle thickness of 1/10.
In order to use the screw to adjust the die and punch the concentric position.
Punching hole should be unloaded slot die, - the Kong Moan on the die seat and fixed by screws, then the die base is fixed on the machine body, punch and die gap around the uniform adjustment can be blanking.
