Radial balance mechanism for automatic wire arranging device of multi-wire cutting machine

Abstract

The invention discloses a radial balance mechanism for an automatic wire arranging device of a multi-wire cutting machine, which is used for ensuring that cutting metal wires on a coiling and uncoiling wheel are arranged sequentially. The radial balance mechanism comprises a frame, wherein cutting metal wires (15) are guided and arranged on a coiling and uncoiling wheel (16) through a wire guide pulley (1) and a tension control pulley (9). The radial balance mechanism is characterized in that: the frame is provided with a slide block (4) which can move along the axial direction of the coiling and uncoiling wheel (16); the slide block (4) is provided with a swinging wire guide pulley (11) which can swing along the radial direction of the coiling and uncoiling wheel (16); and the cutting metal wires (15) are guided and arranged on the coiling and uncoiling wheel (16) through the wire guide pulley (1), the tension control pulley (9) and the swinging wire guide pulley (11). The radial balance mechanism has a simple structure, can automatically balance tension and direction during coiling and uncoiling and always keeps tangential with the coiling and uncoiling wheel and vertical coiling and uncoiling, so that the uniformity of wire arrangement and constant stress are ensured, a cutting effect is ensured and the quality of a cutting product is greatly enhanced.

Description

technical field [0001] The invention relates to a multi-wire cutting machine, in particular to an automatic wire arranging device for a multi-wire cutting machine, in particular to a radial balance mechanism of the automatic wire arranging device for a multi-wire cutting machine. Background technique [0002] Multi-wire cutting is a new cutting method that brings abrasives into the workpiece processing area for grinding through high-speed reciprocating motion of metal wires, and cuts hard and brittle materials into hundreds of thin slices at a time. At present, the metal wire of the multi-wire cutting machine is usually guided by multiple pulleys to be transmitted to the take-up and pay-off reels, some as many as 20, although it can achieve the role of guidance, but there are too many pulleys and no automatic balancing device, especially in There is no automatic balancing device in the radial direction of the take-up and take-up reel, which may easily cause the metal wire to...

Problems solved by technology

At present, the metal wire of the multi-wire cutting machine is usually guided by multiple pulleys to be transmitted to the take-up and pay-off reels, some as many as 20, although it can achieve the role of guidance, but there are too many pulleys and no automatic balancing device, especially in There is no automatic balancing device in the radial direction of the take-up and take-up reel, which may easily cause the metal wire to be unable to maintain a tangential and perpendicular take-up and take-up line with the take-up and take-up reel at the same time, so that the metal wires cannot be wound in an orderly manner. reel

In this way, when the metal wire runs and cuts repeatedly, it is easy to cause excessive changes in the tension of the metal wire

Especially in high-speed cutting, excessive tension changes will easily lead to the signs of wire saws on the cut products, and even the possibility of wire breakage, resulting in adverse consequences
