Pull pin type diamond rope saw and manufacturing method

Abstract

The invention discloses a pull pin type diamond rope saw and a manufacturing method. The pull pin type diamond rope saw comprises a steel wire rope and a plurality of diamond string beads, wherein the steel wire rope is sleeved with the diamond string beads; the string beads are formed by sintering a matrix pipe and a diamond working layer; at least one group of holes are radially formed in the matrix pipe; pull pins penetrate through the steel wire rope in the matrix pipe and the holes on the two sides of the matrix pipe; the string beads are stringed by the steel wire rope, and subjected to injection molding to form an anti-rotation diamond rope saw with the diameter of 3-5.5mm; and an injection molding material is infused into the string beads in a direction of the steel wire rope, and filled to the peripheries of the pull pins, and the diamond string beads are clamped, so that the string beads are prevented from rotating relative to the steel wire rope in a cutting process.

Description

technical field [0001] The invention discloses a pin-pull diamond wire saw and a manufacturing method thereof, belongs to the technical field of diamond wire saws or wire saws according to the International Patent Classification (IPC), and particularly relates to a diamond wire saw with a diameter of Φ3-Φ5.5mm in cutting During the process, the relative rotation of the beads and the wire rope. Background technique [0002] Most of the existing diamond wire saw diameters are above 7.2mm, such as figure 1 As shown, it is mainly composed of a number of diamond beads a, steel wire rope b and rubber-plastic spacer c. After the diamond beads are strung into the steel wire rope, it is put into the injection molding machine to inject the plastic layer or heat-press the rubber layer in the vulcanizer to form Rubber or plastic spacer sleeves to make diamond wire saws. Diamond beads are composed of a cylindrical base and a cylindrical working layer sintered on the cylindrical base. T...

Problems solved by technology

[0003] However, the minimum outer diameter of the traditional diamond wire saw is about 7mm, the largest is about 11mm, and the outer diameter of the inner core wire rope is about 4mm, so there are the following disadvantages when cutting stone: First, the cost of manufacturing materials is high, such as the cost of high-quality steel wire rope, The cost of the diamond working layer; second, because of the large diameter, the size and power requirements of the corresponding matching wire saw cutting machine are large, thereby increasing the investment in equipment costs; When cutting stone, the kerf becomes larger. Taking a Φ7.2mm diamond wire saw as an example, the kerf will reach about 9mm

However, through our tests, this measure cannot avoid the rotation of the diamond beads during cutting. The reason is that the rubber-plastic material in the hole is thinner than the surrounding rubber-plastic material layer and cannot resist a large cutting torque. The layer of rubber and plastic material in the hole will be sheared to make the diamond bead rotate
