Process steps of deep processing of drive shaft

The shaft is an important part of the mechanical structure. It supports the rotation of other rotating parts (such as gears, pulleys, etc.) and transmits motion and power. At the same time, it is connected to the machine channel through bearings (rolling bearings and sliding bearings). All parts of the shaft 1 are rotated about the shaft, thereby forming a shaft-based assembled shaft assembly. In the design of the shaft, not only the shaft itself, but also the entire structure of the shaft system components must be tightly connected.

The drive shaft is a rotating body with high speed and little support, so its dynamic balance is very important. Usually, the drive shaft processing plant must undergo a dynamic balance test and adjust it on a balancing machine.Deep processing of drive shaftProcess steps:

1. First, drill a center hole at both ends of the forging blank, and use a few steps to rough the outer circle.

2. For tempering;

3. For each step of the semi-finished car, there is a margin for the outer circle and length, and then the middle frame car is taken to the total length;

4. The through hole on the drill pipe shaft on the center frame;

5.Deep processing of drive shaftDrill tapered holes at both ends, insert partitions at both ends, and drill holes in the center hole to prepare for polishing;

6. Fine turning the outer circle and step surface of each gear, plus grinding allowance, and cutting grooves and chamfering on the outer circle of the car;

7. Grind the outer circle and step plane of each gear to the appropriate size;

8. Machining each thread on this lathe after assembly.

Deep processing of drive shaftIncluding the following steps: forging, normalizing, rough turning, fine turning, deep hole drilling, hobbing, oil drilling, then pre-degreasing, degreasing, hot water cleaning, cold water cleaning, activation treatment, ultrasonic rinsing, chemical cleaning and drying a series of cleaning work.

If the quality of the drive shaft is not good, the serious consequence is that it will cause the drive shaft to break, making the car unable to drive, and directly causing serious problems. Therefore,Deep processing of drive shaftBe sure to pay attention to quality.

Automatic weaving machine how to install and maintain

Fully automatic weaving machine is a kind of large-scale industrial equipment, which needs regular maintenance to ensure the normal operation of the machine and help to extend the service life of the machine. The maintenance failure of the machine will affect the normal operation of the machine, the machine parts will be damaged, and the service life of the equipment will be affected over time.

Strengthening Personnel Management and Improving Overall Quality

Jinglian Machinery Company issued a preliminary plan in 2019 to strengthen labor discipline and on-site management, so that employees can develop a good working habit and create a good working environment. Since February this year, the plan has been officially implemented. Starting from labor discipline, gfd, site environment and living environment. Continuously strengthen daily inspections and impose corresponding penalties on those who do not comply with the management system. In a short period of one month, the whole factory area has taken on a new look. In the past, cigarette butts were everywhere. Now it is difficult to find one. The working environment of the workshop has changed more. The whole workshop is clearly planned. The materials and workpieces are placed in an integrated way. The clothing of employees is worn.

Various updates and improvements bring new features to Beijing Union

Since the beginning of 2019, Jinglian Machinery Manufacturing Co., Ltd. has continuously made various improvements within the company, and the factory regulations, labor discipline, gfd, work and production environment, staff catering and other aspects have grown. The standardized operation of the production workshop and the inspection and inspection of each process are even more strict and strict. At present, the internal quality inspection basically realizes no leakage, no loss and perfect and clear records.

Machining industry knowledge

In order to let customers know more about our company and the machinery manufacturing industry, I will give you a detailed introduction to our company's various production equipment and machinery manufacturing industry knowledge. Machine tool is a machine that processes metal blanks into machine parts. It is a machine that makes machines, so it is also called "working machine" or "machine tool". It is customary to refer to machine tools for short. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc., but all parts with high precision requirements and surface roughness requirements are generally required to be cut on the machine tool.

Mechanical processing industry knowledge-boring machine

Today we introduce some historical stories about boring machines and some related knowledge. 1, the earliest boring machine designer-Da Vinci boring machine is called "the mother of machinery". Speaking of boring machine, we have to talk about Leonardo da Vinci first. This legendary figure may have been the first designer of a boring machine for metal processing. The boring machine he designed is powered by water or foot pedals. The boring tool rotates close to the workpiece, which is fixed on a moving table driven by a crane. In 1540, another painter drew a picture of "fire engineering" with the same boring machine. At that time, the boring machine was specially used for fine addition of hollow castings.
