Embodiment 1

[0025] The driving device includes a controller 4-1, a solenoid valve 4-2, a throttle valve 4-3 and a telescopic rocking cylinder 4-4; the piston rod of the telescopic rocking cylinder 4-4 is hinged with the support of the rocking table 4-9, which is The cylinder barrel is hinged on the base bracket 4-10; the controller 4-1 controls the reversal of the solenoid valve 4-2, and controls the flow and pressure of the throttle valve 4-3; the solenoid valve 4-2 controls the telescopic rocking cylinder 4- 4, the throttle valve 4-3 controls the movement speed and stroke of the telescopic rocking cylinder 4-4;

Embodiment 2

[0027] The driving device includes a controller 4-1, a motor and a cam; the controller 4-1 controls the motor; the cam is fixed on the output shaft of the motor, and forms a cam pair with the bottom of the rocking table 4-9.

[0028] like figure 2 , 3-1 As shown in and 3-2, the band sawing machine swing type sawing feeding device 4 in the embodiment 1 realizes the method for sawing, and the specific steps are as follows:

[0029] Step 1. The base bracket 4-10 is fixed on the working table of the sawing machine by the hexagon socket head screw; the oil pump drives the clamping hydraulic cylinder 4-6 to push the movable end of the clamp, and the workpiece is clamped on the swing table 4-9; the clamping hydraulic pressure Pressure sensors on the cylinders transmit pressure data to the controller in real time.

[0030] Step 2: The oil pump drives the telescopic rocking cylinders 4-4 to telescopically move, so that the rocking table swings around the base bracket, thereby causin...

Abstract

The invention discloses a swing-type sawing feeding method of a band sawing machine. In order to improve the sawing efficiency and precision of the existing band sawing machine and reduce the sawing load, it is necessary to develop a swing sawing method. The driving device of the band saw machine swing type sawing feeding device adopted in the present invention drives the swing table; the swing table is fixed on the support shaft, and the clamping hydraulic cylinder and the clamp are installed on it; the encoder measures the swing angle and the swing angular velocity of the swing table; The clamping hydraulic cylinder is equipped with a pressure sensor. The sawing method of the present invention: the base support is fixed on the working table of the sawing machine; the movable end of the clamp is clamped by the hydraulic cylinder to clamp the workpiece on the swing table; the driving device drives the swing table to swing around the base support; the band saw machine saws the workpiece Cutting; the workpiece swings under the drive of the swing table, so that the direction and angle of the saw blade sawing the workpiece change constantly, so as to realize the swing sawing of the workpiece. The invention realizes the oscillating sawing of the workpiece, reduces the cutting load, protects the saw blade, and reduces power consumption.

Description

technical field [0001] The invention belongs to the field of sawing machine tools, in particular to a swing type sawing feeding method for a band sawing machine. Background technique [0002] Band sawing machine is the basic means of production in the equipment manufacturing industry and one of the main equipment for material processing. Band sawing machines are widely used in various fields such as steel, machinery, automobiles, shipbuilding and aerospace due to their high machining accuracy, less material loss and high productivity. Swing sawing refers to adding a continuous, controllable and regular swinging motion to the saw blade frame or workpiece during the sawing process, so as to change the cutting method of changing the sawing direction at all times. With the continuous development of science and industry, swing sawing technology has been more and more widely researched and applied due to its advantages of reducing cutting force and power consumption, prolonging t...
