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 advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

The main shortcomings of the four-roll calendering method in the production of inner lining

At the same time, the airtight layer film to be used on the guiding device is guided and enters the centering compound platform through the film conveyor belt. On the centering compound platform, the airtight layer film and the transition layer film are combined to form an inner lining. . The composite inner lining layer enters the winding device through the film conveyor belt for winding, and the hard polyester film is put on the winding. Similarly, the winding temperature is lower than 40 ℃, and the inner lining film is rolled on an I-shaped reel. At this point, the inner liner is produced and enters the forming process for use. Main technical parameters The main technical parameters of the four-roll calendering method for the production of inner lining are as follows; calender power 4×40kW; single-layer film thickness 0.4~3.0mm; film width composite centering error ≤ 2mm; film winding uniformity error. Main advantages and disadvantages The advantages of the four-roll calendering method to produce the lining layer are mainly manifested in the following aspects: (1) faster production speed; (2) better surface quality of the produced film; (3) lower temperature of the rubber compound; ( 4) Lower equipment investment.

The four-roll calendering method mainly has the following shortcomings in the production of inner lining: (1) Since the rubber material fed into the roller gap of the calender is a reciprocating rubber strip, the rubber material has a certain amount of accumulation on the roller gap. The accumulated rubber is rolled into the nip for several times before being rolled, so it is easy to entrap air and make the rolled film contain air bubbles. (2) Because it is easy to form bubbles, the calendering method is only suitable for calendering to produce films that are not too thick. Generally, the thickness of the calendered film is not more than 3mm. For thick products (such as transition layer film), only the pasting method can be used. Production. (3) Since the roller of the four-roll calender is of no belt type and adopts the layered method, the cross-sectional shape of the inner lining produced by the calendering method can only approximately meet the structural design requirements. (4) The thickness error of the film is affected by the amount of accumulated glue. Therefore, the feeding should be carried out continuously and evenly to keep the amount of accumulated glue constant.
