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

Introduction to the Production Process of Precision Small Screws – China Hardware

There are many accessories that we are ignored,small to glasses,bag to airplanes.In these machines and the great human dream behind are inseparable from a small thing–screw.And a good screw can't be separated from a good processing methods,such as small the 1.0 precision screw be used in precision instruments to the large extra-long screw be used in wind turbines and even aircraft.So,what kind of the production techniques are there for precision screws?

Precision electronic screw have to be electroplated before they can be used,as we know,electronic screws are precise and small,so it is difficult to electroplate them.In the case of a small number of electroplating factories will choose to mix different specifications of precision screws together for plating,but will cause uneven electroplating of screws resulting in product scrap. Therefore,we must clean the precision electronic screws before electroplating and then cooperate with excellent electroplating of the screws.

When electroplating that the electronic small screws shouldn't be matched with hard parts to affect the quality of the screw products.

Firstly:It is difficult to meet the quality requirements of different screws electroplating under the conventional electroplating process.

Second:The specification of hardware screw is too close,so will choose electroplating the large size and external hexagon bolts to electroplate separately when plating,otherwise it is difficult to distinguish after the completion of electroplating.

Thirdly:The heavier screws and the lighter screws are electroplated separately,and and the smaller screws and the larger screws are electroplated separately.Otherwise the two kinds of screws may be bruised and damaged in the electroplating process.

Fourth: the two types of screws that are easy to get stuck together should be electroplated separately. Otherwise, the screws of two different specifications and models will get stuck together and form a ball during electroplating, which will easily lead to failure in electroplating. Even after the screws are electroplated, it is difficult to separate the two types of screws.

Thread cutting: generally refers to the method of machining the threads with a forming cutting tool or grinding, mainly including turning, milling, tapping, threading, grinding, polishing and thread whirling. When turning, milling and grinding threads, the transmission chain of the machine tool ensures that the turning tool, milling cutter or grinding wheel moves along the axis of the workpiece accurately and uniformly for each revolution of the workpiece. When tapping or threading, the tool (tap or die) rotates relative to the workpiece, and the first formed thread groove guides the tool (or workpiece) to move axially.

Thread rolling: The processing method of plastically deforming the workpiece to obtain the thread with a forming rolling die is also commonly referred to in the industry as cold heading. The machines used in this production method are generally single-die machines, multi-station machines, and Clamping machines, etc. It is more faster producing time and lower cost by this method, but compared with the cutting process, the head and tail of the screw produced by this process are naturally formed, and the appearance is relatively round. It is not as angular as the cutting process with the beautiful appearance .

Each method has its advantages. Although the speed of the cutting is not as fast as cold heading, its accuracy is higher than the cold heading. The cold heading process produces more quantity and faster speed, and lower cost, especially for the precision small screws, the cold heading process is more cost-effective than cutting process.
