What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

Application of micro lubrication processing in gear processing

Quasi-dry machining is a new type of machining method that replaces traditional lubrication and cooling methods with micro-lubrication.It has been applied in some enterprises.Under quasi-dry cutting conditions, the cutting process is different from traditional wet cutting. For example, the feed speed, cutting depth and cutting speed are different from traditional cutting, which is mainly manifested in the cutting edge of the cutting tool generally using negative chamfering to protect the cutting edge. ; The cutting principle involves a wider range of factors.At present, the theoretical basis of quasi-dry cutting is far less mature than the traditional metal cutting theory, and it is difficult to use a theory to analyze the processing mechanism of quasi-dry cutting.

Hobbing has a certain particularity to its cutting motion, but it has something in common with regard to dry cutting processing theory and cutting mechanism.Its cutting theories include: green cutting theory, metal softening theory during cutting, low temperature brittleness and improved cutting cooling.The specific contents include: (1) Theoretical analysis of cutting force when the cutting tool edge is worn and when it is not worn; (2) The reason for the generation of sawtooth chips; (3) The effect of metal softening; (4) The roughness quality of the machined surface ; (5) MQL cooling and lubricating effect.Surrounding these theories and specific content can guide us to better apply quasi-dry machining to gear hobbing, so as to achieve a good machining effect, a longer cutting tool life, and a clean machining environment.

In order to achieve a good machining effect, the general idea of ​​using quasi-dry cutting in gear hobbing is to increase the cutting speed, shorten the contact time between the cutting tool and the workpiece, and allow the chips to take away a large amount of cutting heat; supplemented by low-temperature cold air And micro lubrication technology.Adopting this kind of thinking is mainly based on the fact that most of the cutting energy will be converted into heat energy, and it is expected that the heat will be quickly taken away by the chips, and the heat conducted to the cutting tool and the workpiece will be minimized.In this way, it is beneficial to extend the life of the cutting tool and reduce the thermal expansion of the workpiece.During high-speed gear hobbing, even under ideal conditions, a small amount of cutting heat is absorbed by the cutting tool. In the current application, the cutting heat of the cutting tool is cooled by compressed air, and the heat dissipation effect is obvious. If it is combined with low-temperature cold air, Will achieve better processing results.
