Manual slitting machine Common problems and solutions

Quality or equipment problems encountered in Manual slitting machine cutting are more difficult to identify and deal with than original volume defects. Traders are inexperienced in this area. They often go around looking for someone to negotiate with, but may not be able to solve the problem.

　　The common problems in the shearing process are divided into longitudinal shearing series, transverse shearing series, blanking series and equipment maintenance series.

　　Analysis of common problems in slitting processing

　　In the longitudinal shearing process of steel, many machining centers (regardless of equipment) have some similar common problems. For example, burrs, sickle bending, staggered winding, uneven winding of multiple strips, edge waves after longitudinal shear, etc. Common is the burr and sickle bend.

　　1. What are Burrs and Sickles

　　If such a problem arises, the first thing to consider is to query the omcc mini program or application, which can quickly query the burr and sickle bend of the sheet:

　　The burrs and sickle bends in the shearing process are similar to, but slightly different from, the defects in the main lines of steel mills (continuous annealing, hot rolling, etc.).

　　When the coil is unrolled, it will be found that the cross section of the strip edge is inconsistent. One section is the cutting section and the other is the tearing surface, which occurs alternately. The burr of the whole strip section is also large, and the width tolerance changes greatly. In essence, it is also a form of sickle bending.

　　Similar fluctuations and changes in cutting section and width will not affect the use of low-demand users, but will have an adverse impact on high-precision, high-quality subsequent processing (such as shelves with high requirements for sickle bending, stamping burr loss will lead to pits, etc.), not to mention the production of products with shearing accuracy of more than 0.1mm.

　　Longitudinal cutting burr and sickle bending defect analysis

　　The elimination and improvement of the two major defects of longitudinal burr and sickle bending mainly focus on the longitudinal cutting blade and its auxiliary equipment. We can check and control some key parameters.

　　Situation: After installing the blade, measure the clearance at different angles of the same cutting edge. Blade clearance is measured every 90°. The structure shows that the difference between the four measuring points is 0.12mm.

　　Conclusion: The inconsistent blade clearance will not only affect the stress distribution of the blade during shearing, but also affect the long-term stability of the blade. During the shearing process, the cutting edge is in the state of spade bending, which will not only produce burrs and sickles bending, but also produce edge waves when it is serious.

　　Cause analysis: The reasons for inaccurate positioning are as follows:

　　1. The working face of the longitudinal shear gasket is damaged

　　The parallel tolerance of both ends of the longitudinal shear gasket is plus or minus 0.002mm. The convex spot error that can be detected by the naked eye is greater than 0.1mm. If there is an ordinary bump on the gasket, basically once there is a bump, the accuracy cannot be guaranteed, which directly affects the accuracy and quality of the product after shearing.

　　Typical pattern of gasket damage

　　The main cause of gasket damage is operation and maintenance. For example, workers do not develop the habit of careful handling, or may fall or be injured during lifting or handling.

　　In addition, the material and surface hardness of the gasket are also very important. The reason why some small processing plants cannot achieve cutting accuracy is that they save costs where they should not. This makes it easy for even minor collisions to lead to such problems, which requires special attention when selecting and purchasing spacer materials.

　　2. The locking problem of the blade and spacer on the knife shaft

　　In order to ensure product size, the tool shaft and blade are usually combined to form a complete whole. Once all the blades and gaskets on the entire tool shaft are unlocked, they will change under the external force of the strip s reaction force

The correct installation of the Slitting machine blade

What is the correct way to install the Slitting machine blade? Next, the slitting machine manufacturer to explain to you.

　　The meaning of the slitting actually refers to the longitudinal cutting of the steel plate, so that the width of the steel plate changes, such as: the width of the steel plate is 100 mm cut into two plates with a width of 50 mm. At this time, you need to use the slitter equipment. In this equipment, it is clear that the blade plays a crucial role.

　　The blade of the slitter equipment also needs to have good toughness to minimize the occurrence of the chipping phenomenon, and the surface finish of the blade is high, usually requiring fine grinding to achieve. Of course, these are comprehensive considerations in terms of cost, efficiency and quality. The most ideal state is to further improve the quality and service life of the blade without increasing the cost.

　　If the thickness of the plate processed is between 3 mm and 7 mm, and the daily processing amount is relatively large, then the blade quality requirements for the slitter equipment are relatively high. In general, the hardness requirements for the blade should be above 65HRC. Secondly, it has good wear resistance, otherwise frequent tool changes will be required in production. This will inevitably affect the production quality and production efficiency.

　　If it is found that there are more obvious burrs on the cut of the plate after cutting, it means that the tool has appeared a large wear, which has affected the quality of the cut. In view of this situation, the user needs to replace the new qualified Slitting machine blade in time. When installing the blade, it should be carried out according to the actual size needed.

　　It is necessary to consider whether the gap between the upper and lower cutting tools of the slitter equipment is reasonable to prevent the use of influence. Of course, during the use of the slitter equipment, we regularly need to carefully maintain the blade to extend its service life as much as possible.
