Mechanical shearing machine is a common metal cutting machine that is widely used in manufacturing, metalworking industry and sheet metal processing. It is powered by a mechanical drive system to cut sheet metal into the desired shape and size. In this article, we will introduce mechanical shearing machine specifically to help you better understand this important metal cutting equipment.
What You Need to Know About Shearing Metal
Shearing metal is the process of breaking or cutting a metal material into desired shapes and sizes by applying force. Shearing is usually done using shearing tools or machines, which can be manual or mechanically driven.
Cutting with the help of a machine is very convenient and easy to handle, so a machine for cutting metal is needed at this time, and a mechanical shearing machine allows us to greatly reduce labor costs and improve efficiency when cutting metal.
What is a Mechanical Shear
A mechanical shear is a common piece of metal cutting equipment used to cut sheet or sheet metal into desired shapes and sizes. It is a shearing device powered by a mechanical transmission system.
Mechanical shears usually consist of the following parts:
Knife Bed: Provides a platform for supporting and positioning sheet metal.
Upper knife and lower knife: realize the shearing of the metal sheet by moving up and down. A cutting area is formed between the upper knife and the lower knife, and the sheet metal passes through the cutting area to complete the cutting.
Transmission system: Usually a traditional mechanical transmission system, such as a crank linkage or gear transmission, is used to transmit the driving force to the cutter to realize the shearing action.
Control system: used to control the start, stop and speed adjustment of the shearing process.
Features of Mechanical Shearing Machine
- Simple structure
The mechanical shearing machine adopts a mechanical transmission system with a relatively simple structure consisting of a small number of transmission parts, which is easy to operate and maintain.
- Low cost
Compared with other types of shearing equipment such as hydraulic shears, the cost of mechanical shears is low, and it is suitable for occasions with limited budgets.
- Fast shearing speed
Mechanical shears usually have a high shearing speed, which can quickly complete the cutting task of sheet metal.
- Wide range of applications
Mechanical shears can be used to cut various metal materials, such as steel, aluminum, copper, etc., and are widely used in manufacturing, metal processing industries and sheet metal processing fields.
- Easy maintenance
Due to the relatively simple structure of the mechanical shearing machine, the maintenance and maintenance are relatively simple. Routine maintenance measures such as regularly lubricating transmission parts, checking knife wear, and adjusting cutting accuracy can keep mechanical shears running smoothly.
- Limited cutting force and precision
Mechanical shears typically have lower cutting force and precision than hydraulic shears or other advanced shearing equipment. It is suitable for cutting tasks that are generally not too demanding, and may have limitations for thicker or harder metal materials.
Advantages and disadvantages of mechanical shears
Besides reliability and price, your first concern with any shearer should be accuracy. Mechanical shears are manually operated while hydraulic shears have CNC functions.
It is worth noting that mechanical shears have more safety hazards than hydraulic shears. That said, mechanical shears can cut very quickly, but should not be operated continuously for extended periods of time. The machine needs to rest and you need to take the time to adjust the blade clearance.
Mechanical shears are shock-resistant, simple, easy to maintain, and environmentally friendly. Since mechanical shears do not require any hydraulic oil, there is no hydraulic waste. Unlike hydraulic shears, which require cooling, mechanical shears don’t waste much energy.
How Mechanical Shears Work
First, the metal sheet to be cut is placed on the knife bed of the mechanical shearing machine, and positioned and fixed. Then, start the mechanical shearing machine through the operation control system, so that the upper knife and the lower knife start to move.
The upper knife and the lower knife contact each other at a predetermined speed and pressure, forming a shear force in the cutting area, and shearing the metal sheet into the desired shape. During the shearing process, the transmission system of the mechanical shearing machine transmits power to the cutter, allowing it to apply sufficient force to the sheet metal to achieve the cutting operation.
After the cutting is completed, the mechanical shearing machine stops, and the metal sheet to be cut is taken out. During the whole work process, it is necessary to pay attention to the safety operation rules and wear appropriate personal protective equipment to ensure the safety of the operator.
The main purpose of mechanical shears
Manufacturing: Mechanical shears are commonly used in metalworking processes in manufacturing to cut sheet metal, sheet metal, and sheet metal material to make parts, components, and assemblies.
Sheet metal processing: Mechanical shears are important equipment in sheet metal processing. They are used to cut metal sheets into required shapes and sizes, and to make sheet metal products, such as chassis, cabinets, and shields.
Metal processing industry: In the metal processing industry, mechanical shears are widely used to cut metal materials such as steel, aluminum, copper, etc., and are used to make metal components, structural parts and parts.
Building and building materials: Mechanical shears can be used to cut metal materials for the manufacture of building and building materials such as roofing panels, wall panels, screens, door and window frames, etc.
Automotive Industry: Mechanical shears play an important role in the automotive manufacturing and repair industry for cutting automotive parts and body panels such as doors, hoods, roofs, etc.
Electrical and electronic manufacturing: Mechanical shears can be used to cut metal materials and make housings, brackets and heat sinks for electrical and electronic products.
Factors to consider when choosing the right mechanical shears
There are several factors that need to be considered when choosing the right mechanical shears. First of all, it is necessary to determine the type, thickness and size range of the metal material to be cut to determine the cutting capacity of the mechanical shearing machine. Secondly, consider the cutting precision requirements and production volume, and choose the appropriate model.
At the same time, pay attention to the reliability, durability and safety performance of the mechanical shearing machine, and choose a brand and manufacturer with a good reputation. Also consider ease of operation and maintenance, and mechanical shear options within your budget. By comprehensively evaluating and comparing these factors, you can choose the mechanical shearing machine that best suits your needs and improves work efficiency.
Shearing machine manufacturer selection advice
When choosing a shearing machine manufacturer, be sure to check their reputation, it will be easy to work with a reputable manufacturer. Of course, it also depends on their technical ability. If they are not professional in technical ability, they will encounter many problems when cutting metal. Also, you need to know how their after-sales service is, so that you can have after-sales protection when you encounter machine problems.
Conclusion
When you choose a mechanical shearing machine, you need to consider factors such as cutting needs, precision requirements, production volume, reliability, safety, operation and maintenance, and budget. By comprehensively considering these factors, choosing a suitable mechanical shear and a reliable manufacturer can meet the needs of metal cutting, improve work efficiency, and achieve a more precise and efficient metal processing process.
