The function of the trimming stamping die is to cut the stretched sheet metal along the process curve to obtain the required edge size. The trimming die should be made in place during the manufacturing process, and if the sheet metal is not properly ground, various problems such as sheet metal rebound and deformation may occur.

Praecipientia molarum fermentorum sunt:

1. Burr: Refers to the sharp corners left on the cross-section of the stamped product during sheet metal cutting. Burrs are inevitable when the sheet metal is separated and can not be eliminated, but can only be reduced. Therefore, there is a certain acceptance principle for the disadvantage of burns in stamped parts, i.e. the length should not exceed 1/3 of the material thickness, and it should not affect the safety of this process, the next process, and the end user. Reage ad occurrentiam flammae: colligendum flammae flammae; Inter convexum et concavem angulos morientur magnus est Parva distancia inter convex et concave angulos conflatiles, etiam angulos verticalorum.

2. Edge trimming and punching deformation: This drawback manifests as edge trimming, warping after punching, hole deformation, etc. The main reasons are analyzed as follows: insufficient pressing force of the pressing core; Distancia inter angulum pulveris et angulum pulveris nimis magna est; Blade damage or unreasonable gaps. 3. Waste does not slide down: The treatment of edge trimming mold waste is very important, as it often leads to mold damage, low production power, and high safety hazards due to the inability and difficulty of discharging waste.

Reages for the above problems are mainly as follows: unreasonable design of waste knives; Lingua tabulae cursa parva est; Fuga deserta habet parvus rursum vacuum; Sequere cum ceteris componentibus molae, sicut si in directo transversae sunt fusilae.

4. Material slag damage: The problem of material slag damage is caused by the introduction of material slag in to the subsequent process during mold trimming, resulting in damage to the workpiece. The frequency of damage is high, which seriously affects the quality and production power of the workpiece. Severe damage requires sheet metal rework, causing great complaints from subsequent customers and increasing production costs, reducing the market competitiveness of the entire vehicle.

Prima causa est quod gapus inter angulum OP20 trimming nimis fortis est, resultat in material extrusion and slag during the trimming process; The cutting edge is inserted too deep, resulting in edge trimming and material residue; Longa labore pallii ad magnitudinem ducit, et percutit pulverem ad opus. Materiale resistentia metallis ipse pauper est, resultant in material slag.

Understanding the manifestations and mechanisms of the shortcomings of edge trimming stamping molds can to some extent guide on-site production. Nunc per controllum omnem proceduram ut qualitatem partium clausum qualificatum esset, poterimus producere produktos cum qualificata qualitate et cognoscere clientes.
