stainless steel mesh weaving machine manufacturers: mechanical processing industry knowledge

In order to let customers know more about the machinery manufacturing industry, I would like to give you a detailed introduction of various production equipment and machinery manufacturing industry knowledge.

Stainless steel mesh weaving machine manufacturer: machine tool is a machine that processes metal blanks into machine parts. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are casting, forging, welding, stamping, extrusion and so on. However, all parts with high precision and small surface roughness generally need to be machined on the machine tool. In general machinery manufacturing, the processing workload of machine tools accounts for 40%-60% of the total manufacturing workload of machines. Machine tools play an important role in the modernization of the national economy. Machine tools are mainly classified according to processing methods and tools used. According to the preparation method of machine tool models formulated by the state, machine tools are divided into 11 categories: lathes, drilling machines, boring machines, grinders, gear processing machines, thread processing machines, milling machines, planers, broaching machines, sawing machines and other machine tools. In each type of machine tool, it is divided into several groups according to the process range, layout type and structural performance, and each group is divided into several series. Here are some simple lathes.

　　Stainless steel mesh weaving machine manufacturer: today we first introduce the lathe.

A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. The lathe is mainly used for machining shaft, plate, sleeve and other workpiece with rotary surface, is widely used in machinery manufacturing and repair shop.

1. Ancient people invented the technology of rotating wood around the central axis with a knife. At first, people used two stumps as supports to support the wood to be rotated, used the elasticity of the branches to roll the rope around the wood, pulled the rope with their hands or feet to rotate the wood, and held a knife in their hands to cut the wood. This ancient method gradually evolved and developed into a kind of "bow lathe". A rope is wound around a pulley two or three times, the rope is placed on an elastic rod bent into an arch, and the to-be-processed is rotated by pushing and pulling the bow back and forth. object.

In the middle of the 2.16 century, a French designer named Besson designed a lathe with a screw to turn the screw and make the tool slide. Use the pedal to drive the crankshaft to rotate, drive the flywheel, and then transmit it to the main shaft to make it rotate. Unfortunately, this lathe is not widely used.

In the 3.18 century, headstock and chuck were born. In the 18th century, someone designed a lathe that uses pedals and connecting rods to rotate the crankshaft, which can store the rotational kinetic energy on the flywheel, and develop from directly rotating the workpiece to rotating the spindle box. The headstock is a chuck for clamping the workpiece.

In 4.1797, the British Maudsley invented an epoch-making tool-rest lathe, which has a lead screw and interchangeable gears.

5. The birth of various special lathes In order to improve the degree of mechanization and automation, due to the invention of tool steel and the application of motors, the lathe has been continuously improved, reaching the level of modern high-speed and high-precision.

　　Stainless steel mesh weaving machine manufacturers: lathes can be divided into many types according to uses and functions

Ordinary lathe has a wide range of processing objects, a large adjustment range of spindle speed and feed speed, and can process the inner and outer surfaces, end faces and inner and outer threads of the workpiece. The lathe is mainly operated manually by workers, with low production efficiency, and is suitable for single-piece, small-batch production and maintenance workshops.

The rotary lathe has a turret tool holder that can accommodate many tools. Workers can use different tools to complete a variety of processes in a clamping workpiece, suitable for mass production. The automatic lathe can automatically complete the multi-process processing of small and medium-sized workpieces according to a certain program, and can automatically load and unload and repeatedly process a batch of the same workpieces, which is suitable for mass production.

Multi-tool semi-automatic lathes can be divided into single-axis, multi-axis, horizontal and vertical. The layout of a single-axis horizontal lathe is similar to that of an ordinary lathe, but two sets of tool holders are installed before, after, on and under the main shaft, which are used for processing discs, rings, and shaft workpieces. Its productivity is 3 to 5 times higher than that of an ordinary lathe.

The copying lathe can automatically complete the processing cycle of the workpiece by imitating the shape and size of the template or sample. It is suitable for small batch and mass production of workpieces with complex shapes, and the productivity is 10 to 15 times higher than that of ordinary lathes. There are multi-tool holder, multi-axis, chuck type, vertical type, etc.
