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

Analysis of Machining, Technologies and Structural Materials for Shaft Parts

1. Analysis of the structure, material and process of shaft parts

(1.)Function and structure of shaft parts

Shafts are used to support transmission parts and transmit torque or movement. The shaft needs to bear the load during work to ensure a certain degree of rotation accuracy. The machining surface of shaft parts usually has inner and outer cylindrical surfaces, inner and outer conical surfaces, step planes and end planes, as well as threads, splines, keyways and grooves.

 

(2. )Materials and blanks of shaft parts

The materials of shaft parts generally include carbon structural steel and alloy structural steel

The blanks of shaft parts include round bars, forgings, and steel castings.

 

(3.) Analysis on the processing technology of shaft parts

①The common axis is the radial design benchmark for each rotating surface. For shafts with high accuracy requirements, the axis of the center holes at both ends can be used as the radial machining datum; for shafts with low accuracy requirements and for rough machining, the outer circular surface can be used as the machining datum

 

②Machining in the order of rough turning→semi-finishing turning→finishing turning, the shafts with high precision requirements should be arranged for grinding.

 

③The spline, keyway, and thread processing on the shaft are arranged after turning and before cutting; for the shaft that needs to be quenched, the thread processing is placed after surface quenching

 

④When the shaft blanks are forgings, normalizing treatment should be arranged, and important shaft parts should undergo multiple heat treatments

 

Typical process of shaft parts

2.Analysis of gear shaft processing technology

(1.)Analysis of parts

 

(2.)Blank selection

 

(3.)Division of processing stages: divided into three stages: roughing, semi-finishing, and finishing

<1>Roughing stage: flush the end face, punch the center hole, and rough the outer circle

<2>Semi-finishing stage: semi-finishing turning, finishing each external circle, threading, keyway milling, gear milling

<3>Finishing stage: study the center hole, rough/finish two outer circles of 20, taper 1:10 truncated cone/30 gear top circle

 

(4.)Benchmark selection: rough turning adopts the outer surface and the center hole as positioning benchmarks, and adopts "one clamp and one top" turning,Two center holes are used as positioning reference when finishing turning and grinding

 

(5.)Heat treatment process: the quenching and tempering process is placed after the rough turning process and before the semi-finishing process; the gear quenching is before the grinding process

 

(6.)The processing process of single-piece and small-batch production
