1, according to the transmission form:
A, mechanical transmission cutting machine: it is A relatively old machine.
B, Hydraulic transmission cutting machine: it is a modern common cutting machine, according to the age can be divided into the first generation of plane guide rail hydraulic cutting machine, the second generation of ordinary four-column hydraulic cutting machine, the third generation of precision four-column hydraulic cutting machine and gantry mobile hydraulic cutting machine.
C, automatic rolling cutting machine: processing the whole piece of leather or textiles, etc.
D, computer control water beam cutting machine: is a modern more advanced cutting machine, do not need to use the knife mold, according to the input program for cutting. The cutting source is the high pressure beam generator.
E. Computer controlled ultrasonic cutting machine: the control form is similar to the water beam cutting machine, and the cutting source is ultrasonic generator.
2. According to the structure mode:
A, rocker arm cutting machine: the cutting parts can be swung of the rocker arm, suitable for leather, natural materials and artificial leather and other non-metal materials.
B. Longmen moving cutting machine: the cutting parts are the cutting head that can be moved along the side of the beam. The knife mold can be fixed on the cutting head or placed on the processed material. The large, computer-controlled gantry cutting machine is equipped with a rotating tool die frame, which can be selected according to the program typesetting; of course, an automatic feeding mechanism shall be provided accordingly.
1, the oil pressure cutting machine hydraulic cylinder has a rod cavity and no rod chamber containing gas produced by low speed crawling, can be through repeated operation of the hydraulic cylinder to achieve the purpose of exhaust, if necessary in the pipeline or the hydraulic cylinder two cavity exhaust device, exhaust in the hydraulic system to work.
2. For low-speed crawling caused by the improper design gap of the hydraulic cylinder, the sliding coordination gap between the cylinder and the cylinder body, the piston rod and the guide sleeve is H9 / N or H9 / f8 and H8 / f8. According to the experience of the author, the cylinder diameter and rod diameter of the hydraulic cylinder are from small to large, so the coordination gap is designed according to this, for larger cylinder diameter (? The coordination clearance of 200mm) and rod diameter (140mm) appears to be too large. In the actual process, the phenomenon of hydraulic cylinder crawling is more with small cylinder diameter. The coordination clearance of the sliding surface of the hydraulic cylinder in foreign countries is generally designed as 0.05mm∽0.15mm. From the actual comparison results, the low speed crawling problem of the hydraulic cylinder is significantly improved. Therefore, this method is recommended for the hydraulic cylinder with a large cylinder diameter
3, cutting machine hydraulic cylinder guide element uneven friction of low speed crawling, it is recommended to use metal as a guide support, such as QT 500-7, ZQAL 9-4, such as non-metal support ring, it is recommended to choose the oil size stability, especially the thermal expansion coefficient should be small, and the support ring, must strictly control the thickness of size tolerance and thickness uniformity.
Cutting press machine manufacturers analyze the small knowledge of cutting machine and the construction of cutting machine
Cutting machine is an indispensable equipment in some light industries. The traditional concept is that the cutting machine is a machine that cuts and processes the material with the force of the machine movement. Some changes have taken place in the modern cutting machine, and advanced technologies such as high pressure beam and ultrasonic are used in leather cutting technology, but people still summarized these equipment in the equipment of cutting machine.
The cutting equipment with high degree of automation includes: computer-controlled moving head cutting machine, laser cutting machine (oscillation tool), high pressure water beam cutting machine and computer cutting machine, etc. In addition, Italian and British USM produce a projection cutting machine with oscillating tools and visual observation devices to scan the leather, or projection on the leather to guide the cutter to arrange the set of the cutting sample on the leather
At present, there are various models of cutting machines produced by different manufacturers in the Chinese market. Now, according to its product performance, we suggest that you compare and choose from the following aspects:
1. According to their transmission mode, structure and use:
1, according to the transmission form:
A, mechanical transmission cutting machine: it is A relatively old machine.
B, hydraulic transmission cutting machine: it is a modern and more common cutting machine.
C, automatic rolling cutting machine: processing the whole piece of leather or textiles, etc.
D, computer control water beam cutting machine: is a modern more advanced cutting machine, do not need to use the knife mold, according to the input program for cutting. The cutting source is the high pressure beam generator.
E. Computer control ultrasonic cutting machine cutting machine: the control form is similar to the water beam cutting machine, and the cutting source is ultrasonic generator.
2. According to the structure mode:
A, rocker type cutting machine: the cutting parts can rocker swing, suitable for the cutting of natural materials
B. Gantry cutting machine: the cutting parts are the cutting head that can move along the side of the beam. The knife mold can be fixed on the cutting head or can be placed on the processed material. The large, computer-controlled gantry cutting machine is equipped with a rotating knife die frame, which can be selected according to the program layout, and the automatic feeding mechanism shall be provided accordingly.
C, flat plate type cutting machine: the difference between it and the gantry type cutting machine is that the beam is directly cutting, there is no movable cutting head. Flat plate cutting machine is divided into: beam fixed or beam can be moved back and back and the platform skateboard can be moved front and back two categories.
D, four-column precision cutting machine: multiple cylinders drive the four-column automatic balance connecting rod structure, to ensure that each cutting point is the same force, to ensure the balance accuracy of the upper and lower working table.
3. According to the purpose of the processed parts:
A, special cutting machine: suitable for the blister processing of the suction plastic cutting machine.
B, horizontal cutting machine: suitable for processing tire materials.
The conventional cutting machine is composed of twelve parts, including power, transmission mechanism, hydraulic system, electrical system, knife mold setting mechanism, feeding mechanism, operating system, lubrication system, safety system, pressure head and fuselage.
According to different styles of models, there will also be its unique structure, such as: pressure head moving mechanism, automatic balance mechanism, cutting plate displacement mechanism, etc. Depending on the performance, sometimes other auxiliary devices are added.
