Zhejiang Deli machine Manufacture Co., Ltd.(http://en.zjdljc.com/) <![CDATA[Working Principle of Sawing Machine]]> http://en.zjdljc.com/en/news/41.htm 2023-06-28T14:02:00Z 2023-06-28T14:02:00Z The hydraulic transmission system consists of a hydraulic circuit composed of components such as pumps, valves, oil cylinders, oil tanks, pipelines, etc. It completes the lifting of the saw beam and the clamping of the workpiece under electrical control. Through the speed control valve, stepless speed control of the feed rate can be implemented to meet the needs of sawing different materials of workpieces. The electrical control system consists of a control circuit consisting of an electrical box, control box, junction box, travel switch, electromagnet, etc., used to control the rotation of the saw blade, lifting of the saw beam, clamping of the workpiece, etc., to achieve normal cutting cycles according to a certain working program.
Before starting the lubrication system, oil must be added according to the requirements of the lubrication parts of the machine tool (wire brush shaft, worm gear box, active bearing seat, worm bearing, upper and lower shafts of the lifting oil cylinder, and clamping screw of the sliding surface of the movable vice). The worm gear and worm in the worm gear box are lubricated by a 30 # engine oil bath, which is injected through the oil plug hole in the upper part of the worm gear box. The box surface is equipped with an oil mark. When the saw beam is in the lowest position, the oil level should be between the upper and lower limits of the oil mark. After one month of trial use, the oil should be changed. Afterwards, the oil should be changed every 3-6 months. There is an oil drain plug at the bottom of the worm gear box.
The saw blade drive is installed on the worm gear box, and the electric motor drives the worm and worm gear inside the worm gear box through a belt pulley and triangular tape, driving the driving wheel to rotate, and then driving the saw blade around the active/passive wheel rim for cutting and rotating motion. The feed motion of the saw blade is controlled by a hydraulic circulation system composed of a lifting oil cylinder and a speed regulating valve, which controls the lowering speed of the saw beam and thus controls the feed (stepless speed regulation) motion of the saw blade. The saw brush rotates at the place where the saw blade produces chips and rotates in the direction of the saw blade. The cooling pump provides coolant for cleaning and removes chips from the teeth. The coolant is located in the cutting fluid tank on the right side of the base, directly driven by a water pump to supply the coolant.
Press the emergency stop (stop) button, rotate clockwise, the oil pump motor works, the gear pump works, and the oil enters the pipeline through the filter screen. Adjust the overflow valve to ensure that the system working pressure meets the requirements. On the contrary, if the button is pressed inward, all motors will stop working. Press the clamp button to clamp the workpiece, the electromagnetic valve operates, and hydraulic oil enters the left side of the clamp cylinder. The right hydraulic oil returns to the oil tank, and the left clamp clamps the workpiece.
When the saw beam descends, press the working clamp, and hydraulic oil enters the rod chamber of the lifting cylinder through the electromagnetic valve; The hydraulic oil in the rodless chamber returns to the oil tank through a solenoid valve and a one-way speed control valve. Press the lowering button for the quick lowering of the saw beam, and the hydraulic pressure works through the solenoid valve. The oil enters the rod chamber of the lifting cylinder, while the oil without the rod chamber returns to the oil tank through the solenoid valve. Press the up button when the saw beam rises, and hydraulic oil enters the rodless chamber of the lifting cylinder through the electromagnetic valve; The oil in the rod chamber returns to the tank through the solenoid valve. Press the clamp release button to release the workpiece, and hydraulic oil enters the right side of the clamping cylinder through the electromagnetic valve; The left hydraulic oil can return to the oil tank through the solenoid valve, and the left jaw moves to the left to release the workpiece.
The analog input and output module of the system makes the monitoring of the sawing process widely meaningful. For example, as long as the feedback of saw blade deformation is added to the sawing machine, the sawing speed can be adaptively adjusted. By adding a servo valve, the speed and position control of the sawing process can be optimized. The management function of the system makes the management of materials and workpieces more convenient. The Chinese interface of the system and real-time graphical status display make the operation more user-friendly and intuitive.

Circular saw machine, also known as circular saw machine, is divided into fully automatic and semi-automatic. The circular saw blade undergoes a rotating cutting motion while also following the feed motion of the saw blade box (see figure). Circular saw machines are divided into three types according to the feed direction of the saw blade: horizontal (horizontal feed), vertical (vertical feed), and pendulum (swing feed around a pivot point). In addition, there are various specialized circular sawing machines, such as the shaking head sawing machine used for cutting large casting sprues and risers; Saw and drill joint machine tool for rail cutting and drilling.
Band saw machine
The circular saw belt is tensioned on two saw wheels and is driven by the saw wheel for cutting. There are two main types of band sawing machines: vertical and horizontal. The saw frame of a vertical band saw machine is vertically set, and the workpiece moves during cutting to cut the curve contour of the sheet metal and formed parts. The saw belt can also be replaced with a file chain or sand belt for filing or polishing. The saw frame of a horizontal band saw machine is arranged horizontally or obliquely, feeding in a vertical direction or swinging around a pivot point. The saw band is generally twisted 40 ° to maintain the saw teeth perpendicular to the workpiece. Horizontal sawing machines can be divided into scissor type, double column type, and single column type; According to usage, it can be divided into manual type (economical manual feeding and manual cutting of materials) and automatic type; According to the automation program using the controller, it can be divided into manual type (semi-automatic manual feeding) and fully automatic type (automatic feeding and automatic cutting)
Hacksaw machine
The saw bow equipped with a saw blade moves back and forth, feeding by swinging the saw frame around a pivot point. The machine tool has a simple structure, small volume, but low efficiency. There are two types of motion trajectories for the saw blade of a hacksaw machine: straight and curved. When moving in an arc, the saw bow swings around a pivot point for a small angle, and each tooth has a larger cutting amount, which makes it easy to remove debris and has higher efficiency. This method is mostly used in modern hacksaw machines.
