Main Structure and Characteristics of Shearing Machine

Mar. 06, 2020

Shearing machine is equipped with a protective grid to play a role of safety protection. The adjustment of the stopper interval is driven by a motor, and is transmitted to the left and right screw rods through a transmission shaft and a pair of sprocket pairs, which drives the stopper frame to move forward and backward along the guide rod. The two button operations are the forward and backward coarse adjustment buttons. When you press and hold the buttons, the back gauge moves forward and backward quickly.

1. The tool holder adopts steel structural parts. Under the action of the thrust of the oil cylinders on both sides, it can swing around the fixed pin to complete the cutting action without the need for a guide rail system.

2. The frame adopts steel structural parts, the left and right vertical plates, the workbench and the blanking plate are welded into an integrated structure, and the internal stress is eliminated by tempering after welding, so the overall rigidity is good and the chaos is high. The system pressure is supplied by the oil pump. Under the control of the electro-hydraulic system, each valve can realize the sequential action of the presser foot and the knife holder and the shearing of the knife holder, and other operation specifications. Shears-the main structure and characteristics of the machine.

3. The flat steel shearing machine is installed on the end face of the fuel tank, and the fuel tank is fixed on the beam of the rack, which is convenient for cleaning and disassembly.

4. The back gauge is installed on the tool post and swings with the tool post. It has a mechanism for quickly adjusting the blade gap, and the scale value is displayed on the scale.

5. Shearing machine This machine uses three-phase system power (380V) for power supply. The control circuit voltage (220V) is provided by the control transformer. The DC power (+ 24V) required for the solenoid valve of the execution circuit is provided by the transformer and silicon rectifier. The device is mainly composed of a set of pressure cylinders. Before the tool post goes down, the plunger of the pressure cylinder overcomes the action of the spring to press down the sheet. After the shearing is completed, it is reset under the action of the spring. At the end of the cutting, the tool post quickly returns automatically under the action of the return cylinder. There is an adjusting hand wheel on the button box to fine-tune the positioning, and a mechanical digital display on the button box shows the interval of the back block.

Maintenance method of plate shearing machine

1. Operate strictly in accordance with the operating regulations.

2. Add lubricating oil regularly, fixedly and quantitatively according to the requirements of the lubrication chart before each start-up. The oil should be clean without sedimentation.

3, the machine must always be kept clean, unpainted departments anti-rust grease.

4. The lubricating oil in the electric bearing should be replaced and refilled on schedule, and the electrical department is often checked for normal, safe and reliable work.

5. Check whether the V-belt, handle, knob, and button are damaged on time. Replace them if they are severely worn, and report for replacement.

6. Check and repair the switches, insurances and handles on schedule to ensure their reliable operation.

7. Lubricate the machine tool and clean the machine tool 10 minutes every day before leaving work.

8. It is strictly forbidden for non-designated staff to operate this equipment. It is usually necessary for people to leave the machine and stop it. industry.
