The cutting machine is an indispensable equipment for some light industry industries. The traditional idea is that the cutting machine is a machine which is pressed by the force of the motion of the machine to the cutting machine. Some changes have taken place in modern cutting machine, start the high pressure water bundle, ultrasound and other advanced technology used in leather cutting technology, but people still to conclude these devices in the class of cutting equipment. The high degree of automation of the cutting equipment includes: computer controlled movable head cutting machine, laser cutting machine, high pressure water beam cutting machine and computer cutting machine. In addition, Italy and Britain the unsharp mask a projection cutting machine production company, this kind of equipment on the blanking with oscillation type cutting tools and visual observation device, used for contour scanning was carried out on the leather, or in the leather on the projection model to guide the cutting work arrangements material on leather on the set of rows. At present in China, there are various models on the market at home and abroad by different manufacturer production cutting machine, now according to its product performance, we recommend that you compare to choose from the following several aspects: A, according to their transmission mode, structure and use classification is as follows: 1, according to the transmission form points: A, mechanical cutting machine: is the old type machine. B. Hydraulic transmission cutting machine: it is the more general cutting machine of modern times. C, full automatic roller compaction cutting machine: it is used to process the whole sheet of leather or textiles with the method of sandwich. D, computer control water beam cutting machine: it is modern and advanced cutting machine, without the use of knife die, according to the input procedure. The cutting source is high pressure water beam generator. E, computer control ultrasonic cutting machine: the control form is similar to the water beam cutting machine, the cutting source is the ultrasonic generator. 2. According to the structure way points: A, rocker arm type cutting machine: punching parts for can swing arm, suitable for leather, natural materials and cutting non-metallic materials such as leather. B, gantry cutting machine: the cutting part can be moved around the beam, the die can be fixed on the cutting head, or it can be put on the processed material. The large, computer-controlled dragon gate cutting machine is equipped with a rotating blade rack, which can be arranged according to the program and select the corresponding cutter. Of course, automatic feeding mechanism is required. C, plate type cutting machine: the difference between it and the gantry cutting machine is that the beam is directly cut, and there is no movable cutting head. Flat panel cutting machines are divided into two categories: beam fixation or crossbar movement and table skateboard movement. D, four-column precision cutting machine: double oil cylinder, four-column automatic balance connecting rod structure. 3, according to the processing unit USES points: A, the special cutting machine: is suitable for blister blister cutting machine processing. B, horizontal cutting machine: suitable for processing tire material. 2. Mechanical cutting machine: general mechanical transmission of the cutting machine is fast, stable running (after adjust stroke limit no change), blunt shear; The biggest drawback is that it is noisy. So since the 1960s, it has been gradually replaced by a hydraulic transmission cutting machine. Three, hydraulic cutting machine: judging function of hydraulic cutting machine is the main basis: size and punching shear velocity. The punching force is very large, but the cutting speed is very low, or the cutting speed is very high, but the machine that has a very small punching force cannot successfully complete the blanking task. For mechanical transmission, the cutting speed of the cutting machine is high, about 250 times. The cutting speed is variable value, the average cutting speed is: 200 mm/SEC. The speed of the hydraulic cutting machine is generally greater than 75mm/SEC. Cutting machine of mechanical transmission and hydraulic transmission of the cutting machine differences, mainly determined by the different characteristics of two types of transmission: mechanical transmission is rigid, and hydraulic transmission have certain flexibility. Hydraulic cutting machine is characterized by: when the cutting head by die cutter ACTS on the processing of instantaneous effect of the pressure inside the cylinder did not reach the rated pressure, pressure will contact (cut into the work) as time increases, until the electromagnetic directional valve receives the signal, the reversing valve reversing, cutting head start reset; At this time, the pressure in the cylinder may not meet the rated pressure due to the time limit of the pressure oil entering the cylinder. In other words, the system pressure failed to reach the design value, and the blanking has been completed. Four status, the cutting machine use: 1. Mechanical transmission of the cutting machine, although some manufacturers are continuing to produce, some small, individual manufacturers are still in use, but this form of cutting machine will be eliminated. 2. The hydraulic power cutting machine is still in the mainstream. In hydraulic cutting machines, a large number of them are used in the 8-20 ton swing arm cutting machine. The plate type and the longmen cutting machine are mostly used to compare large manufacturers, which are more suitable for the cutting of leather and artificial non-metallic materials. 3. The automatic cutting machine is already in use in our country. Due to the improvement of the modernization of the manufacturing industry, there may be a certain market in the near future. But in the near term it will not be possible to replace the hydraulic cutting machine.
