Title of Invention : Horizontal Multi Diamond Wire Saw

Cutting Machine

[1]

Technical Field

The present invention relates to designing a machine for cutting stones using diamond wire saws in horizontal array in close loop and, more particularly, multiple diamond wires running in coaxial motion with an Improved structure capable of cutting various rigid or super rigid materials.

[2]

Background Art

Multi wire saw Machine are identical design too, they are composed of ail mentioned components above except that several rings of DW run by single drive wheel (drum) and two drums of guide wheels positioning precise in-out motion, separate pulleys with adjustable tension for each wire.

Multi wire saw machine design made of different constructions to meet the cutting dimension of Maximum standard stone blocks with size of 3.2mx2mx2m, Construction made of 2/4 columns with high of about 6-7m , 13-14 m in length and width varies according to the No wires it handle.

DW tension Is operated independently because of separate DW rings. Machine suppliers keep on developing their product to meet the high performance and they meet required efficiency in operation. The only limitation is the complexity In design and high investment on making the construction design which to raise cost on machine user on the initial investment and maintenance cost, a wire saw composed of sintered metal bonded diamond beads, wherein countless such diamond beads, each formed with a through hole, are stringed together by a pliable yet strong cord. This type of wire saw is disadvantaged by its relatively large cord diameter, which leads to a kerf typically more than 1 mm in width. In addition, this type of wire saw is also unmanageable when operated along curved cutting paths with small radii of curvature and Incurs a considerable production cost.

Summary of Invention

In view that the shortcomings ot the prior art require immediate improvement, the inventor of the present invention, based on more than 10 years of experience in the related industry, strived to figure out ways to make a wire saw machine for cutting stones of different types which is giving more production capacity with less maintenance down time, incurs a low manufacturing cost. Which reduces the material wastage and ease of performing operation with Improved safety. After repeated experiments and extensive research, the inventor finally succeeded in designing and developing a Multi diamond wire saw machine with an improved structure.

The disclosed Diamond wire saw machine features ,

1. Mini Portable multi-wire saw plant for cutting natural stone or semi products.

2. Mini plant would use the available stone quarry machines/ facilities.

3. New small, simple design structure and easy in operation.

4. Multi section cutting in horizontal motion by one close loop DW/several closed loops DW. 5. One DW tension system to run the machine.

6. DW running in horizontal cutting motion by two drive wheels sets.

7. DW running in coaxial motion.

8. Each dive wheel contains a sprag clutch (one way bearing for one closed loop DW model).

9. Easy change of DW since it is a single wire (for one spiral closed loop DW).

All above allow simple structure design or possibility to make portable cutting machine beside stone mines to cut off transportation cost as stone block.

[4]

Technical Problem

Existing vertical DW cutting machines produce a large amount of material wastage and the bottom layer of the stone block cannot be recovered and extreamly difficult and unsafe to unload the cut out slabs. Without individual tensioning mechanism the cutting quality is being affected unreasonably.

Consequently, setting up plant away from the quarry tend to higher mobilization cost, since around (25-35) % of the material turned to waste powder form by sawing meaning. In addition, loading / unloading by meaning of gantry crane, water reclamation plant and factory construction civil work cost is additional cost to any natural stone project to make at least unpolished slabs products.

[5]

Solution to Problem

Machine with a new design to allow one DW in a closed loop running in a coaxial motion toward stone blocks allowing a cutting force direction to each other, the cutting direction of DW is in horizontal motion -whether stone blocks toward machine or machine running toward blocks- and tension system made of one tension pulley because of one DW running within machine ,in addition the running of DW is by several drive wheels , set of drive wheels run by one shaft in clockwise motion, another set run by another shaft in counter clockwise motion. Each drive wheel supported by sprag clutch (one way bearing) which allow pulling DW for the cutting speed and allow DW to be tensioned in all drive wheels by one tensioned pulley which is tightened by mean of linear stroke by a jack (hydraulic, mechanic, pneumatic) with a set value of tension kg unit. In addition, a way of portable machine to be hold within block and execution of cutting to be done.

Advantageous Effects of Invention

Here the invention is the new machine designed by the inventor.A study has been conducted by the inventor comparing salient features of our WSM design and other existing machines in market. First of all , the no of machines , which are using multiwires in horizontal cutting is very few ,as of this concept and idea is very fresh to be implemented. Apart from vertical cutting there are a lot of advantages are there in horizontal cutting like, reduced material wastage safer operations and easy material handling after production, etc.

This Horizontal Multi-wire saw machine has following features which stands out from the other manufacturers,

The Machine is designed as a portable machine, to be used in quarry or workshops , where it can be moved from one site to another with very limited change over time

This machine has been designed with individual wire tensioning; most of the other machines in market are having mono tensioning system.

We have been checking with existing manufacturer like SKYSTONE, PEDRINI,GASPARI-MENOTTI, UNIVERSO,BIDESE, PELLEGRINI and we have been convinced as our designs meets all the necessary features that all the similar machines have.

Based on the concept of maximizing the wires performance, the new design optimizes wires performance and reduces comprehensive cost. Repair and maintenance cost: outstanding structure design allows customers get quick and easy maintenance. Additionally our excellent protection design and practice have proved that we can bring lowest cost in maintenance to our clients

Set-up: very easy and fast. Within 1 day of set-up, machine can start operation
