What is the difference between CNC shearing machine and mechanical shearing?

1. The transmission mode is different, the CNC shearing machine is hydraulic transmission, and the mechanical shearing machine is mechanical transmission.

2. The shearing principle is different, it is the pendulum type of the CNC shearing machine, and the mechanical shearing machine is the gate type.

Introduction to CNC shearing machine: CNC shearing machine refers to the technology of using digital instructions composed of numbers, words and symbols to realize the action control of one or more shearing machine equipment. CNC shearing machine generally uses a general or special computer to achieve digital program control, which usually controls mechanical quantities such as position, angle, speed and switching quantities related to the flow direction of mechanical energy.

The production of CNC shearing machine depends on the emergence of data carriers and binary form data operations.

Introduction of mechanical shearing machine: The mechanical shearing machine adopts the clutch structure in the form of resistance key and open gear transmission, and adopts more advanced electrical appliances (foot switch, manual switch) to operate, with low noise and easy operation and maintenance. It adopts all-steel welded structure, which is simple in structure, easy to operate, beautiful in appearance and low in energy consumption.

It is widely used in metallurgy, light industry, machinery, hardware, motors, electrical appliances, automobile maintenance, hardware manufacturing and other metal sheet processing industries.

CNC shearing machine is usually only hydraulic pendulum type, but it may also be a gate type, CNC and mechanical look at the word to know the difference is that one can control the backgauge material through the system to improve the accuracy of the shearing, and the other can only be manually adjusted, so satisfied?

The difference between the categories of shearing machines in this statement is not very clear, the numerical control is considered from the control mode, and the mechanical type is considered from the transmission principle, which is interspersed with each other. The CNC shearing machine can contain the CNC mechanical shearing machine, and the mechanical shearing machine can contain the CNC mechanical shearing machine.

Summary. Hello friends, the shearing coefficient of the CNC shearing machine is usually between to. If the shearing coefficient is too low, it means that the cutting capacity of the machine is insufficient to meet the requirements of the workpiece; If the shearing factor is too high, it will cause the machine to be overstressed, which will reduce the life and stability of the equipment.

In actual operation, it is necessary to determine the most suitable shearing coefficient according to the specific workpiece material and thickness, combined with the parameters and performance of the CNC shearing machine.

Hello friends, the shearing coefficient of the CNC shearing machine is usually between to. If the shearing coefficient is too low, it means that the cutting capacity of the machine is insufficient, and the Wushan fingering method meets the requirements of the workpiece; If the shearing factor is too high, it will cause the machine to be overstressed, which will reduce the life and stability of the equipment. In actual operation, it is necessary to determine the most suitable number of shearing systems according to the specific workpiece material and thickness, combined with the prudent parameters and performance of the CNC shearing machine.

Excuse me, but please go into more detail?

The shearing coefficient of the CNC shearing machine refers to the ratio between the required shearing pressure and the elastic modulus of the plate, the thickness of the plate, and the length of the cut when shearing the metal plate. The formula is: shearing coefficient = shear force (n) (elastic modulus of plate (n mm) plate thickness (mm) cut length (mm)).

The smaller the shear factor, the smaller the shear force required, the smaller the deformation and permanent deformation or dismantling caused by the cutting process, and the better the shear quality. The general value of the shearing coefficient on the left and right is the optimal value range for the CNC shearing machine to cut the metal plate. In the operation process of the CNC shearing machine, the shearing parameters should be adjusted according to the different materials and thicknesses of the shearing according to the needs, so that the shearing coefficient can be as close as possible to the optimal value, so as to achieve the best shearing effect.

At the same time, reasonable maintenance of CNC shearing machine to maintain the good condition of the blade also has an important impact on the quality of shearing.

1. The uses of all shearing machines are as follows:

1. Cold-formed forming line shearing machine: such as the special shearing machine configured on the production line of automobile longitudinal beam cold-forming line, carriage side baffle production line, color steel plate forming line, etc.;

2. Steel structure production line shearing machine: mostly used for angle steel, H-beam automatic production line to complete the shearing process;

3. Plate opening and leveling line shearing machine: used for plate uncoiling and leveling line, high-speed shearing machine designed to meet the fast shearing requirements of the production line, the thick plate line is mostly hydraulic high-speed shearing machine, and the thin plate line is mostly equipped with pneumatic shearing machine; The high-speed line is equipped with flying shear machine, continuous production, high efficiency.

Plate shears (English name: plate shears; Guillotine shear) is a machine that uses one blade to reciprocate in a linear motion relative to the other to cut a sheet. It is by means of the moving upper blade and the fixed lower blade, using a reasonable blade gap, to apply shear force to the metal sheet of various thicknesses, so that the plate is broken and separated according to the required size.

Shearing machine is one of the forging machinery, and its main role is in the metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment.

According to the different transmission methods, the shearing machine is divided into mechanical transmission type and hydraulic transmission type. The shearing machine with a shear thickness of less than 10mm is mostly mechanically driven, and the shearing thickness is more than 10mm is mostly hydraulically driven.

According to the position of the upper blade to the lower blade, the shearing machine can be divided into flat edge shearing and oblique edge shearing. When the flat edge is sheared, the sheet metal is in contact with the full length of the upper and lower cutting edges at the same time, and the shear force is large, the power consumption is large, and the vibration is also large. However, the shear quality is better, and the sheared sheet is relatively straight, without twisting and deformation.

The transmission mode of the flat blade shearing shearing machine is mostly mechanical transmission, which is mostly used for small shearing machine and thin plate blanking. Bevel edge shear is a gradual shear method, so the instantaneous shear size is less than the width of the sheet. The quality of the bevel edge shear is not as good as that of the flat edge shear, and there is distortion and deformation.

However, the shear force and energy consumption are smaller than that of the flat finch blade shear, so it is used in large and medium-sized shearing machines.

The shearing machine is divided into linear type and swing type according to the different movement methods of its knife holder. The linear structure is relatively simple (like a gate, so it is also called a gate), easy to manufacture, the blade cross-section is rectangular, and the four sides can be used as a blade, so it is more durable. The knife holder of the pendulum shearing machine swings around a fixed point when shearing, and the advantages are that the friction and wear between the upper and lower shear blades are small, the blade deformation is small, and the shearing accuracy is high.

However, the swinging knife Shenxiang morning frame bears forward and reverse alternating torque during the shearing process, so the width of the knife holder cannot be too large. Therefore, the pendulum structure is mainly used for shearing machines with a plate thickness of more than 6mm and a plate width of no more than 4 000mm.

Technical parameters of the shearing machine. The main parameters of the shearing machine are expressed in terms of shear thickness and shear sheet width. The main technical parameters of the shearing machine are: shearing thickness, shearing width, shearing angle and stroke times.

The common shearing machines on the market include flame cutting machines (shearing machines), plasma cutting machines, and typical shearing machines, but users find that they have many disadvantages in the process of use

1.Flame cutting machine, the use of gas oxygen distribution for cutting, there will be material loss in the cutting process, as well as environmental pollution. Generally, 30 kilograms will be lost after cutting a ton of steel, and if it is a large and medium-sized enterprise with an annual production value of more than one million tons, the loss will be huge.

2.Plasma cutting machine, mainly with the help of plasma cutting technology for cutting, local melting (and evaporation) of the cutting part, can accurately control the cutting length, easy to operate, but the risk factor is high, pollute the environment, and have a certain amount of material loss.

3.A typical shearing machine has high dimensional accuracy, low surface roughness of the shear surface, almost no material loss, but cannot be moved, and the cutting length is limited. If the sheet is too long and the machine does not reach the cutting length, the sheet will be wasted.

According to the needs of the market, the automatic mobile shearing machine developed by Jinhan Ruitu comes with a guide rail, which can avoid the problem of being limited by cutting equipment due to the length and thickness of the board; "Zero" loss in the cutting process, which is more suitable for large and medium-sized steel manufacturers with high annual production volume; In addition, the automatic mobile shearing machine is more intelligent, which can automatically feed and adjust the knife for cutting, which not only reduces labor costs, but also more effectively avoids safety accidents caused by feeding. What's more, the automatic mobile shearing machine conforms to the national policy on energy conservation and emission reduction, and is safe and environmentally friendly during operation.
