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

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

Processing and repairing plastic molds need to know the relevant machine operating skills

Processing and repairing plastic molds need to know the relevant machine operating skills

 

1. Grinding machine processing

After the mold is damaged, some small parts need to be repaired by welding, and the welding to the mold core or the surface of the subsurface can be ground by a grinder (including the actual matching of new parts, and the outer size is large). When the welding volume is small, grinding is definitely the quickest way.

 

Familiar with the knowledge and operation related to the grinding machine, how to load and unload the grinding wheel, the tool setting and feeding method of the grinding wheel, the applicable scope of the grinding wheel, the balance correction of the grinding wheel, the clamping and fixing of the workpiece, etc. As for the adjustment of the balance of the grinding wheel, some companies often do not pay attention to it and do not have this requirement. In fact, this is very irregular.

 

2. Operation of dust collecting grinder

Dust-collecting grinder for rough grinding of parts. For example, after argon welding, the surface of the part is too large, and the shape of the part can be roughly polished by hand.

   

3. Milling machine or rotary arm drilling machine processing

Simpler operation, if a screw is broken on the mold. Drill a hole again on the original foundation and take out the broken screw. For example: the lack of a detector on the mold for induction fixation, and plastic machining of two threaded holes. On the three-plate mold, the through hole of the grab pin of the stripper plate is worn out, and the hole is reamed after increasing the through hole.

 Familiar with the knowledge and operation of related milling machines or rotary drill presses, the selection of drill bits and taps, the selection of rotation speed, the clamping and fixing of workpieces, etc.



 

4. Electrical discharge machining

After the mold is damaged, electric discharge machining will be used after welding repair. Use electrodes to perform electrical discharge machining on the welded parts of the mold. (Repair parts that cannot be repaired manually, such as deep narrow grooves or curved surfaces)

 

5. Precision cutting machine thimble processing

The thimble on the mold is broken or worn, and it needs to be replaced and processed with a new thimble of the same specification, and a precision cutting machine will be used. Processing the length of a thimble should be the easiest thing.

 

Without a precision cutting machine, grinders and grinders or fast wire plastic machining may be used. Familiar with the disassembly and replacement of related grinding wheel cutting discs, the clamping of thimble, the use of jigs, etc.

 

6. Polishing and grinding machine operation

Some parts of the mold cavity have a large welding repair amount. You can first use a polishing machine to hold the grinding rod to rough repair the points, and then use electrode discharge machining or without electrodes and no graphics, some can only rely on polishing and grinding machines manually repair.

 

7. Punch forming machine processing

The punch forming machine is used to grind the outer shape of cylindrical parts. If the grab pin of the three-plate mold on the mold is broken or the forming pin is deformed, this punch forming machine can be used.

 

8. Argon welding or laser welding repair

The damage of mold parts is nothing more than welding repair, inserting, re-preparation treatment, argon welding and laser welding repair have their own advantages. Many mold repairs will be equipped with argon welding machines, and there are fewer laser welding repair machines. If the mold repairs can be repaired by argon welding or laser welding, there is no need to go out for argon welding or laser welding, which can greatly shorten the time for mold repairs. And cost.

 

9. Manual polishing

Some small barbs or crushing of the mold cause scratches or strains on the appearance of the product. Or there are bad marks and rust spots on the mold, which affect the defects of the product surface. Then, the series of polishing actions such as diamond paste, sandpaper, and oil stone must be mastered by mold repairers.

 

Sometimes a file may be used. The file depends on the skill of the hand. It is difficult to master the skill of repairing the mold with the file without a certain time of tempering. Without sufficient equipment and conditions, sometimes only relying on manual skills to make up for it.

 

10. Mold maintenance

After the mold is produced or in production, it is indispensable to clean and wipe the parting surface, apply oil on the guide post and the sliding block, and a series of cleaning and inspection actions. Mold maintenance is the basic skill of mold repair personnel, simple disassembly and cleaning, oiling and maintenance.

 

11. Some tips related to molds

How to quickly and effectively remove broken screws, broken water pipe joints, how to use jigs or fixtures to process some small parts on the mold, how to remove the mold more convenient, etc.

   

The more skills and knowledge a mold repairer masters, the more it is conducive to the rapid development of mold repair work, the more handy it can greatly shorten the mold repair time, so the corresponding requirements for mold repair personnel are higher. Some people may say that lathe processing, CNC machining center, wire cutting, etc. are all available. Isn't it more conducive to mold repair? Of course, "many skills do not overwhelm you", mold repair has the characteristics of mold repair, to a certain extent, it is different from mold opening.

 

Processing and maintenance skills are on the one hand, on the other hand, processing and maintenance personnel need to have the ability to find problems and think independently, and solve them independently. This will be more conducive to personal growth and reflect personal value.
