The automatic uncoiling and blanking line is getting better and better as the automobile industry develops, demands for the surface quality of the car increase, and automation levels rise.
A automobile has to have about 70% of its metal components stamped and molded. The automatic uncoiling and blanking line is getting better and better as the automobile industry develops, demands for the surface quality of the car increase, and automation levels rise. This allows for less waste or scrap-free layout. This will directly assist the auto industry by increasing productivity, lowering prices, and raising quality.
The uncoiler, a shearing machine, a metal straightener, a servo feeder, a press, and stacking parts make up the majority of the typical uncoiler blanking line.
The uncoiling press in the majority of produced blanking dies only requires one stroke to produce a blanking sheet. The most important components of this group of equipment are the leveling device, the press, and the stacking component, and how well they function directly affects the caliber of the processed goods. In order to achieve the goals of straightening and leveling the plate and producing a high-quality flat plate for the following stamping process, the leveling machine continuously changes the bending direction of the strip. This unloads the internal stress of the plate through numerous positive and negative bending corrections of the strip.
The mold is the hub of the entire manufacturing process, and the quality of the end product is directly influenced by the mold's numerous components. During manufacturing, the press drives the die's punching action, and its parameters control the die's processing speed and capacity to shear metal. The stacking step is the final step in the entire production line, and it is in charge of neatly stacking the output plates so that the products are stacked in an organized and neat manner. The quality of the completed sheet is significantly influenced by each beater's position, strength, and frequency of beating.
Improve the use of materials
An uncoiling blanking die can be created, and a practical layout can increase material use. For instance, the material utilization rate for the manual blanking of a given model's front wing is 31.38%, but the material utilization rate for the uncoiling of blanking molds increases by 7.79% to 39.17%.

Enhance product quality and lessen scratches and dings
The automatic uncoiling blanking line can eliminate the bumps and scratches brought on by manual blanking by around 30%. The manual blanking operation will bring about some scratches to the completed product. The blanking piece is easily likely to collide with the mold positioning device during the reclaiming process, which is the primary cause of the scratches on the sheet's surface that result from hand blanking. The blanking sheet is jostled and scratched while being blanked.
Become less labor-intensive while increasing output effectiveness
The blanking method is used to make the majority of automotive cover parts. For instance, when the uncoiling blanking line is not utilized, the upper and lower parts of a given model's side wall production are manually blanked. The surface quality cannot be assured, the labor intensity is quite high, and the manufacturing efficiency is very low. Uncoiling plus blanking is now in use, which significantly raises product quality and manufacturing effectiveness.
lessen operator scrubbing mishaps
When using manual blanking due to the car cover's huge size, such as its side wall measuring 1700 mm 3210 mm, the operator may easily graze their wrists throughout the operation of the top and lower portions (if the labor insurance is fully worn). According to data, practically every production batch of large covering components, such as side walls, has some type of wrist scratch mishap every year, especially in the summer, before a certain plant installed an automatic uncoiler line. When the automatic uncoiler line is employed, there are no more safety accidents due to blanking.
