What are the differences between electric and manual steel bar machines?
LY-3 electric steel bar machine working principle <br>It adopts the vertical pressing method, which is driven by the motor to rotate a shaft with a spiral belt by 360°, and raises the punch vertically at different angles. The elastic impact is struck, and the motor drive screw shaft is linearly arranged on the sample at a distance of 10 mm × 31 points = 300 mm. By moving the positioning device, the second hitting gauge length is 5 mm x 62 dots = 305 mm.
The electric continuous dot-punching machine is a special equipment for the metal tension gauge length (LO).
First, the main technical indicators
1. Standard range: LO=10-350MM;
2, punctuation spacing: 10mm
3, gauge length accuracy: ≤ ± 1% LO (refer to GB228)
4, dot rate: 45 grid / sec
5, motor power: 50W;
6, voltage: 220V;
Second, the structure of the machine host consists of the base, bracket, sample support table, knob, punch, operating lever, assist handwheel, motor, electric controller, action switch, speed setting knob.
Third, the operating procedures
1, adjust the speed of the dot
A. Plug in the power and the indicator of the electric controller lights up.
B. Open the action switch and adjust the rotation speed setting knob from “0†to the appropriate striking speed. At this point, the county hand wheel should turn counterclockwise.
2, sample gauge distance management
A. Push the lever first;
B. placing the tensile test sample into the support table;
C. Adjust the position of the sample support table so that the sample axis corresponds to the dot axis, and then lock the support table.
D. Pull the lever to make the punch contact the surface of the specimen.
E. Open the action switch to cause the punch to impact the sample surface leaving the gauge punctuation.
3, electrical control notes:
A. Please ground the equipment;
B. When the action switch is turned on and the direction of rotation is wrong, the action switch should be turned off immediately. The wiring on the controller terminal should be adjusted.
1. Select COM and CW to short-circuit, then the motor rotates clockwise;
2. Select COM to short the CCW, then the motor rotates counterclockwise.
C. The action switch only controls the motor to operate and stop. It is not used as a power interruption. If it is not used for a long time, please disconnect the power plug from the power supply.
LB-40 steel bar machine is independently developed and manufactured by Shanghai Leiyun Test Instrument Manufacturing Co., Ltd. according to the new standard of Zui. It is also called continuous punctuation machine. It has two types: manual type and electric type. It is used for marking marks of garden steel, flat steel, steel pipe, section steel and other non-ferrous metal materials for tensile specimens.
LB-40 steel bar machine (rebar gauge) [Technical requirements]
Each time you shake it, you can score 41 punctuation.
The distance between the punctuation is 10m/m, the error is not more than ±0.15m/m, and the total length is 300m/m and 400m/m. The tip of the punctuation is made of ball bearing round steel with a hardness of not less than RC55 degrees.
LB-40 steel bar machine [advantages]
The structure is precise, easy to use, high in efficiency, accurate in operation, and easy to inspect and repair.
LB-40 manual steel bar machine [Usage]
Print 10mm pitch
When using, put the sample material into the (sample holder) slot, adjust the silk base according to the length of the sample material, adjust the length of the wire sample and the diameter of the circular material to adjust the sample holder, and unscrew the sample holder. The upper fixing screw can move the sample holder back and forth. According to the requirements of the material, align the center of the diameter and then shake it with your left hand. Pull the handle down until the tip of the punctuation touches the sample material, and tighten it slightly. Shake the handle with your right hand and turn it clockwise (clockwise).
Print 5mm pitch
To print a 5mm pitch, first print a 10mm pitch, then use your left hand to gently push the screw to shake the hand to shift the sample by 5mm. Continue to print once, after printing, take the sample
