Description

Multi-wire cutting machine swing contact table

technical field

The invention relates to a reciprocating rocking structure of a workbench of a multi-wire cutting machine. A workpiece is bonded to the workbench, and together with the workbench performs circular arc swing motion, which has remarkable cutting performance for processing high-hardness materials.

Background technique

The general cutting principle of multi-wire cutting machine is that the cutting wire net is wound between two or more grooved wheels, and the motor drives the grooved wheels to perform high-speed reciprocating motion. At the same time, according to the cutting speed, the feed speed of the worktable is adjusted to ensure Pressing force between workpiece and wire mesh until it is cut into multiple sheets. Multi-wire wire cutting machines generally use two types of free abrasives and fixed abrasives. Free abrasives are the cutting method of sandblasting mortar on the surface of the cutting wire mesh, and fixed abrasive cutting is the method of directly using diamond wires and blasting cutting fluid at the same time. However, general cutting methods cannot process high-hardness materials, especially materials with a Mohs hardness above 8, and general cutting methods cannot process them into sheets.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Referring to the accompanying drawings, this embodiment includes a swing assembly 2, a sliding seat 3, a fixed seat 4, a ball screw 5, a linear slider 6, a servo reducer I7, a servo motor I8, an angular contact ball bearing 9, a timing belt 10, Pulley 11, servo reducer II12, servo motor II13; the fixed seat 4 is fixed on the cutting chamber of the multi-wire cutting machine, connected with the sliding seat 3 through the linear slider 6, the servo motor I8 and the servo reducer I7 The servo reducer I7 is connected with the ball screw 5, the ball screw 5 is fixed on the fixed seat 4, and the ball screw 5 is connected with the sliding seat 3; the servo motor II13, the servo reducer II12 is installed on the sliding seat 4, the servo motor II13 is connected with the servo reducer II12, the servo reducer II12 is connected with the pulley 11, the synchronous belt 10 is installed on the pulley 11, and the synchronous belt The two ends of 10 are fixed on the rocking assembly 2, and the synchronous belt 10 is tensioned by angular contact ball bearing 9.

In this embodiment, the oscillating assembly 2 is bonded with a processed part 1 .

There are two main actions when the swing contact worktable is working, the downward movement of the worktable in the feed direction and the swing movement of the swing assembly. Generally, wire cutting only has the downward movement of the worktable in the feed direction; the servo motor Ⅰ8 and the servo deceleration Machine Ⅰ7 drives the ball screw 5 to rotate, thereby driving the sliding seat 3 to move up and down. In the working state, the sliding seat 3 moves downward, and the workpiece 1 also moves downward accordingly, forming a pressing force between the workpiece 1 and the cutting line mesh 14 During the high-speed reciprocating motion of the cutting wire mesh 14, the cutting wire slowly cuts the processed material into sheets, and the controller controls the servo motor Ⅰ8 and the servo reducer Ⅰ7 to precisely control the feed speed of the workbench to avoid wire bow overshoot. Cause disconnection.

During the cutting process, the swing accuracy of the workpiece 1 directly affects the slice quality. In order to ensure the running accuracy of the swing assembly 2, the swing assembly 2 is connected to the worktable through an arc-shaped slider. In order to ensure that the position of the swing assembly 2 is accurate and controllable, The drive swing assembly 2 adopts a synchronous belt to drive the swing assembly to move. The two ends of the timing belt 10 are fixed on the swing assembly 2, and the timing belt is tensioned through the angular contact ball bearing 9. The timing belt 10 is installed on the pulley 11. According to the position of the swing assembly, the controller controls the movement of the servo motor Ⅱ13, and then passes The servo reducer II 12 drives the pulley 11 to rotate back and forth. After the timing belt 10 moves to the limit position, the controller controls the servo motor II 13 to reverse direction, thereby driving the rocking assembly 2 to perform rocking motion.

When the swing contact workbench is working, the feed direction of the workbench and the swing direction of the swing assembly are shown in Figure 3.
