Description

Tension balancing device of cutting line for single-line slicing machine

Technical Field

The utility model relates to a wire-electrode cutting technical field specifically indicates a tension balancing unit of line of cut for single line slicer.

Background

The machine tool is used for machining parts and relates to two fields, namely plastic materials and hard and brittle materials. The machine tool for processing the plastic material, namely a metal cutting and processing universal machine tool, has wide performance range; the machine tool for machining the hard and brittle material parts is a special machine tool (except an electric machine tool) for machining a diamond tool, and the machine tool is also a special machine tool for machining the hard and brittle material parts by using a diamond wire tool with a slicing function.

The cutting range of the machine tool with the slicing function comprises hard and brittle materials such as neodymium iron boron magnetic materials, ferrite magnetic materials, ceramics, crystals, semiconductors, gems, quartz, glass, crystals, precious stones, hard alloys and the like, and the development conditions are as follows:

1. the initial slicer is an outside-garden slicer (including a multi-blade slicer) appearing in the fifties of the nineteenth century, and the blade is thick, so that the processing effect is poor, and the cut material needs to be processed for the second time, so that the processing cost is high, and the material waste rate is high;

2. due to the fact that the saw-bow-shaped slicing machine for the multi-strip steel bars uses particle sticky frosting, cutting efficiency is low, clamping precision of the strip steel bars is high, difficulty is high, and labor is wasted;

3. the Japan inner circle slicer is introduced in the seventies, the processing effect and the efficiency are greatly improved, but one operator can only operate 2-3 machine tools, and the integrated processing belongs to the labor-intensive industry, and the machine tools adopt rough open processing, so the environmental pollution is great;

4. since the twentieth century, full-automatic slicing machines began to be put into the domestic market for full-closed processing, thereby solving the environmental problem of three wastes; in addition, one operator can operate 20-30 machine tools, the integrated processing development of hard and brittle materials is promoted, and the full-automatic slicing machine with more than ten thousand tables in China is used up to now;

5. the multi-line slicing machine for the mortar steel wire is basically used for processing solar single-product silicon, and is withdrawn from the market due to the problems of environmental pollution, low efficiency, high investment cost and the like;

6. a diamond wire multi-wire slicer appeared. Due to the breakthrough of the high-tech technology for coating the micro-particle diamond, the diamond wire multi-line slicing machine quickly enters the field of processing of hard and brittle material parts. Its greatest advantage is the processing of large-volume products, which are currently in saturation in the market. Because the machine tool is large, complex and high in investment cost, the corresponding cutting roller (commonly called as a roller) must be processed for processing the specification of each product, and the cutting roller has high processing precision and high daily use cost. Therefore, the product is difficult to popularize for medium and small batch processing and medium and small enterprises.

7. Diamond wire single line slicer. This microtome technology is also currently on the market as a multi-line microtome. The investment cost and the use cost are difficult to be reduced to the state that medium and small enterprises can be popularized.

(1) The structure of taking up and paying off adopts two independent diamond wires to take up and pay off synchronously, so the structure is complex, and meanwhile, steel parts of a take-up and paying-off cylinder need to be customized, and the diamond wires need to be processed by diamond wire production enterprises when being wound on the cylinder, so the use is inconvenient; each line is about 30 kilograms in weight, the rotation inertia is large, and the no-load loss of a matched driving motor is large;

(2) the cutting diamond wire processing adopts a cutting roller process, the structure is complex, and the cutting roller must be replaced when one product specification is processed. A special hydraulic tool is matched for replacing the cutting roller, and an operator needs to be trained to a qualified level, so that the use requirement is high, and the operation is inconvenient;

(3) because the rotation inertia of the take-up and pay-off drum is large, the tension control difficulty is large (the diameter of the diamond wire is small), and the control cost of the equipment is increased. Meanwhile, the tension is controlled by an open loop, so that the tension control precision is relatively low;

(4) the lifting structure of the working table adopts a rolling guide rail pair and a ball screw pair, is arranged at the position of the Z axis of the frame and is provided with an adjusting structure in the horizontal direction, so the structure is complex, and the difficulty is caused by the matching of the three wastes treatment of the shield;

(5) if winding and wiring are carried out on the cutting roller or in the case of wire breakage, a manual method of operating personnel (which must be trained to be qualified) is adopted, so that the difficulty is high, and the labor and the time are wasted.

In a wire cutting device, the tightness of the diamond wire tension and the tension change degree directly influence the cutting efficiency and quality of a processing material, and the tightness of the diamond wire cannot be changed in the cutting process once the current tightness is set, but the tightness change is large when the diamond wire is reversed, so that the problem that the diamond wire is excessively tightened and broken easily occurs; in addition, in the cutting process, the tension of the diamond wire can also change to a certain degree, and if the tension cannot be balanced in time, the tension control precision of the diamond wire is poor, so that the cutting effect is easily influenced.
