Operating procedures for portable stone cutting machines

The stone cutting machine is composed of a cutting knife group, a stone conveying platform, a positioning guide plate and a frame. The stone cutting machine is made of iron and is suitable for dry cutting and wet cutting of various types of stone, building materials, tiles, granite, marble, cement board, red brick, refractory brick, etc. It is an essential tool for home decoration.

The stone cutting machine can cut stones at different depths and process stones less than 1m3. It can turn waste into treasure, greatly save stone resources, and is also beneficial to environmental protection. It can perform mechanical cutting on various types of stones with high processing efficiency. In addition, it effectively utilizes small stones to reduce production costs.

A multi-knife multi-stage stone cutting machine composed of a cutting knife group, a stone conveying platform, a positioning guide plate and a frame. The cutting knife group is placed on the upper part of the stone conveying platform and on the frame, and the positioning guide plate is fixed between the cutting knife groups; the cutting knife group is composed of a motor, a belt, a knife wheel shaft, and a cutting tool, and the cutting tool is fixed on the knife wheel shaft. This stone cutting machine can cut stones at different depths and process stones less than 1m3. It can turn waste into treasure, greatly save stone resources, and is also beneficial to environmental protection. It can mechanically cut various types of stones with high processing efficiency. In addition, it effectively utilizes small stones to reduce production costs.

Since the linear motor drive and the spindle of the portable stone cutting machine are the same part, there is no lead screw connection, no backlash, and accurate movement. The portable stone cutting machine achieves high response and high tracking, as well as high-precision position control, prevents wire breakage, and can maintain stable processing in the best discharge state, improves the discharge efficiency and processing accuracy of the portable stone cutting machine, and overcomes the surface stripes in wire cutting.

The portable stone cutting machine uses linear motor drive technology. Sodick, a Japanese company, first used linear motor drive on portable stone cutting machine tools. At the 7th Beijing International Portable Stone Cutting Machine Tool Exhibition in 2001, it launched the AQ550L linear motor driven portable stone cutting machine.

The CAD/CAM technology of the cutting process of the portable stone cutting machine has been further improved. After years of development and research, the cutting process of the portable stone cutting machine can use computers to draw pixel images of parts, automatically program, and control the processing trajectory. In recent years, the portable stone cutting machine has integrated the CAD and CAM modules to form a CAD/CAM system from pixel graphics input to processing process control. Some portable stone cutting machines have also developed a relatively complete CAD/CAM system including process parameter optimization selection on the basis of establishing a process database.

Operation procedures

I. Before work

1. Wear work clothes and goggles. Female workers with long hair should put their hair up and wear work hats.

2. Check the power switch, the tightness of the saw blade, the saw blade guard or the safety baffle in detail. The operating table must be stable and there should be sufficient lighting for night operations.

3. Turn on the main switch and test it for a few turns without load. It is allowed to start only after confirming safety.

II. During work

1. It is strictly forbidden to operate with gloves. Wear a mask or face shield if dust is generated during operation.

2. Do not attempt to cut small workpieces that are not clamped.

4. This cutting machine is only allowed to cut profiles.

5. Do not perform strong sawing operations, and the motor must reach full speed before cutting.

6. No one is allowed to stand behind the saw.

7. Do not lean over or around the saw machine, and do not release any hand or raise the arm from the saw or workpiece when the saw blade has not stopped.

8. Do not operate when the guard is not in place, and do not put your hand within 15 cm of the saw blade.

9. Before repairing or replacing accessories, you must cut off the power supply and wait for the saw blade to stop completely.

10. If you find any abnormal sound, you should stop and check immediately.

Three. After work

1. Turn off the main power

2. Clean and tidy up the workbench and site

The double-piece table stone cutting machine has a circumferential spring staggered tooth clearance elimination structure. Two thin table stone cutting machines are set together. Each table stone cutting machine has two circumferential through grooves. A short column is installed on the end face of the table stone cutting machine to install the spring. When assembling, the spring has sufficient tension so that the left and right sides of the two thin table stone cutting machines are respectively close to the left and right sides of the wide table stone cutting machine to eliminate the gap on the tooth side.

There are two ways to support the ball screw pair of the table stone cutting machine on the workbench. One is the single support form; the other is the two-end support form. The table stone cutting machine clamps the outer ring of a pair of tapered roller bearings and pre-tightens them, improves the rotation accuracy of the bearings, increases the rigidity of the bearing device, and reduces the vibration of the bearings when the machine is working. The functions of the main pins are as follows:

① Control line - the selection end of the device. Although there is 4K FLASH in 89C51, in order to facilitate wiring and storage of various programs, the internal program memory is not used. In this way, it is grounded and reads instructions from the external program memory. Stone

② - The selection end of the desktop stone cutting machine to distinguish the reading of the external data memory.

④RESET - reset end. When the input reset signal continues to be high for more than two cycles, the desktop stone cutting machine completes the reset initialization operation.

③ALE - address latch control end. When the system is expanded, ALE controls the low eight-bit address output by the P0 port to be sent to the latch for storage to achieve data and address isolation. In addition, ALE outputs positive pulses at a fixed frequency of l/6 crystal oscillator, which can be used as an external clock or timing pulse.
