Product Introduction

Price of impact test sample gap pulling machine

1、Main purpose and scope of application
We have developed an impact specimen notch hydraulic lathe based on various advanced experiences in this field both domestically and internationally. This lathe is a V and U double blade hydraulic lathe, which has the characteristics of high precision, strong durability, low noise, and beautiful appearance. It is suitable for enterprises in the metallurgical industry, military industry, shipbuilding, mechanical manufacturing industry, and colleges with a large number of impact notch specimens, as well as teaching and practical tools. This device meets the requirements of GB/T229-2007 "Metallic Charpy notch impact test method" for notch accuracy of impact specimens.
The standard configuration of this machine includes one V-U knife each, and the applicable range for cutting materials is 40Cr, 45Cr, 40Ni, 40CrNi, and 50CrNi. When cutting other materials, please contact our company to customize cutting tools. We are dedicated to serving you.
2、Main technical parameters
3Working conditions

1. This machine should be installed in an environment free of vibration and corrosive media. The machine should be installed horizontally on a cement stable foundation with a working face, and the horizontal error should not exceed 5mm/m.
2. Before using this machine, the side door should be opened to inject hydraulic oil (46 anti-wear hydraulic oil) into the bottom of the tank through the buried filter oil mesh to the bottom of the oil cylinder.
3. Using an AC 380V, 50HZ three-phase four wire power supply, the voltage variation should not exceed ± 10% of the rated voltage. There is a power supply wiring at the back of the machine, which is a three-phase four wire system with markingsNThe neutral wire is connected to the power supply neutral wire.

4Structural characteristics and working principle
This machine consists of a knife box, hydraulic cylinder, lubrication mechanism, electrical control, and other parts.
4.1 Start the oil pump and lubrication mechanism to supply oil, press the up or down button, and the puller will run up and down to achieve the purpose of cutting the sample.
4.2 Electrical part: It consists of a leakage protector as the main power supply for the switch, power/off/start buttons, up/down buttons, limit switches, etc.
4.3 After installing the machine, connect the power supply at the back of the chassis(Note: The N line is the neutral line)Power on, the power indicator light is on (red), press the start button, and then press the up or down button. The knife box should be able to rise or fall, otherwise it will cause damage to the three-phase systemLTwo of the wires should be interchanged and connected, and then the knife box should be able to rise or fall by pressing the up or down button, and the machine should enter normal working state(Note: Before working in winter, the machine should be idle for 10-20 minutes).
4.4 Raise the puller to the upper limit position, place the sample into the clamping seat and tighten the sample (the limit block has been set to 27.5mm), press the descent button, and the tool descends to pull the sample. The precision of the sample notch should comply with the provisions of GB/T229-2007.
be careful:
1After each cutting of the sample, the sample should be taken out first before lifting the cutting tool to avoid tool damage.
2After each cutting of the sample, the puller should be cleaned with a brush to maintain the accuracy of the cutting sample gap.

5.1. For repeated or prolonged use, the start button should be pressed before cutting to fully lubricate the guide rail and reduce rail wear.
5.2 After each cutting is completed, the iron cutting in the slot of the cutting tool should be cleaned thoroughly to prevent the iron cutting from squeezing into the machining surface and damaging the workpiece.
5.3 After cutting each day, open the small door at the back to clean the surface of the oil box, remove the filter from the oil box, clean it, and put it back in its original place. To avoid clogging of the oil filter or damage to the machinery caused by overflow of iron chips.
Update hydraulic oil every six months.
