Description

Wire sawing machine with swing mechanism

technical field

The utility model relates to a wire sawing machine with a swing mechanism.

Background technique

In traditional wire sawing machines, the feed movement is generally a linear movement of the workpiece relative to the wire saw wire. When cutting round bar material, the contact length between the wire saw wire and the workpiece changes continuously, which causes changes in the sawing force, deformation of the saw wire, etc., causing vibration of the process system and reducing the shape accuracy of the cutting surface. If the wire saw wire additionally swings during the sawing process, that is, increase the swing motion on the one-way continuous motion sawing machine to keep the contact length between the wire saw and the workpiece constant or shortest, which is beneficial to reduce the change of the sawing force and reduce the wire saw wire. amplitude. Improve cut surface quality.

Utility model content

The purpose of this utility model is to solve the above problems and provide a wire sawing machine with a swing mechanism, which uses a ring-shaped diamond wire saw wire as a cutting tool, and the saw wire moves continuously in one direction, eliminating the impact of cutting speed changes on the roughness and surface Influenced by the damaged layer, it also has the advantages of high cutting speed and high efficiency, and is mainly used for cutting experiments of hard and brittle materials.

In order to achieve the above object, the utility model adopts the following technical solutions:

A wire sawing machine with a swing mechanism, which includes a sawing machine frame, on which a feed servo motor is installed, the feed servo motor drives a sliding plate to move up and down, and a swinging device is installed on the sliding plate in a swinging manner. The guide wheel set, the circular saw wire is installed on the guide wheel set, and an electric spindle is installed on any one of the guide wheel sets.

The oscillating device is a swing saw bow, and the guide wheel set has four guide wheels, which are respectively installed at the four corners of the swing saw bow; the circular saw wire is installed on the four guide wheels; on the swing saw bow, the center point of the circular saw wire is There are two concentric circular arcs in the center of the circle as the rotary guide rails, rolling bearings are installed at the ends of the two supporting shafts I, and the rolling bearings are matched with the upper rotary guide rails; the vertically adjustable support shaft II is matched with the lower rotary guide rails; the oscillating saw The bow is connected with the reversible pinion through the sector gear, and the pinion is connected with the swing servo motor; the two support shafts I and II install the swing saw bow on the lower plate, and the lower plate is driven by the feed servo through the ball screw mechanism. The motor drives the up and down movement.

The working principle of the utility model is: the seamless circular saw wire is wound on four guide wheels, the saw wire is tightened by the adjusting device, and the electric spindle drives the circular saw wire to move in one direction. The feed servo motor drives the ball screw mechanism to drive the feed movement of the lower plate, and the feed speed can be automatically adjusted. In order to ensure that the contact length between the saw wire and the workpiece remains constant or the shortest, a swing device is added to swing the saw bow. The saw wire needs to swing left and right in the cutting plane around the middle point of the saw wire. This point is inside the workpiece to be processed, and the installation of the rotating shaft will interfere with the workpiece. Actually utilize two concentric circular arcs with the midpoint of the saw wire as the center of the circle as the rotary guide rails, the ends of the two support shafts I are equipped with rolling bearings, and the rolling bearings cooperate with the upper rotary guide rails to reduce friction. The supporting shaft II can move up and down and be fixed, and it cooperates with the lower rotary guide rail to eliminate the track gap. When the pinion at the shaft end of the swing servo motor rotates forward and reverse, it drives the sector gear, and the sector gear is fixed with the swing saw bow to drive the swing saw bow to rotate around the center point of the arc.

The beneficial effects of the utility model are:

1. A swing mechanism is added to the sawing machine. During the sawing process, ensure that the contact length between the saw wire and the circular workpiece is constant or shortest;

2. Two concentric circular arcs centered on the midpoint of the saw wire are used as the rotating guide rail to avoid interference between the rotating shaft and the workpiece.
