DURMAPRESS winding machine is a common machine tool equipment in our daily life, is the company's trustworthy machine tool equipment, DURMAPRESS winding machine operation skills of the company is to understand, which the following four steps of winding machine operation steps, I hope you simply understand. 1, pre-bending. When the plate is rolled, a length at both ends of the plate does not bend due to contact with the upper roller, which is called the residual straight edge. The moment… Leer Más "The four steps of the operation of the DURMAPRESS winding machineare simply summarized

The system composition of the hydraulic four-roller plate winding machine: 1, steel structure frame all annealed to eliminate stress, and the welding strength meets the design stiffness requirements.   2, all rollers are forged from high strength steel, after heat treatment, the surface automatically induction hardening after rolling plate.   3, with coil cone equipment and hydraulic balance system.   4, rolling machine under the roller distance can be reconciled can not be adjusted two.   5. The side rollers… Leer Más "The system structure and technical characteristics of hydraulic four-roller plate winder are described

Improve the lubrication premise: the relationship between the forming quality of bending machine and lubricant is very important. Poor lubrication premise or improper selection of lubricant may lead to sheet cracking press brake machine hydraulic. Adjust drawbead parameters or blank holder force: the use of drawbead can prevent flange parts from folding, but its side effect is to increase the activity resistance of the material into the concave die, therefore, improper drawbead parameters may lead to bending machine activity resistance… Leer Más "Poor lubrication of the press brake machine hydraulic may lead to sheet cracking

Hydraulic bending machine is one of the common equipment in modern mold processing. Most CNC bending machine is the main way of working on the piston press, its driving force has characteristics, specific and bending machine mold production process has a great relationship. But it is undeniable that in normal use, the matters needing attention include the following: CNC bending machine is characterized by two parallel movement of the working hydraulic cylinder to form pressure, this pressure is vertical downward,… Leer Más "Hydraulic bending machine normal operation should pay attention to safety matters

When used, the wire is… Leer Más "The importance of the structure and components of the WC67K-100T3200 Hydraulic Press Brake machine

The CNC machine tool of CNC bending machine is used to operate power box, control board, parallel grating ruler and data hydraulic transmission system. The communication between them ensures the high quality characteristics and precise transmission system of the CNC bending machine. The two piston rods are arranged synchronously and controlled by analog signals to prevent the influence of other data signals. To a certain level and can reduce project budget, save the time of actual operation efficiency, from the… Leer Más "How to play the function of the bending machine well?

When out of the process bending process diagram, bending this step is very good to understand；  If you are a novice in bending, you should pay attention to the following points before using the bending machine: 1, distinguish between the first perspective or the third perspective, generally there are symbols in the picture box. The first Angle of view is commonly used in China, according to the law of projection; The third Angle of view is placed on the left… Leer Más "9 points for attention in mechanical drawing bending

WC67K series sheet bending machines lider repetition accuracy is ±0.0004 inches, forming * Angle must use such precision and good mold. The slider repetition accuracy of manual bending machine is ±0.002 inches, and it generally produces ±2~3° deviation under the condition of proper die. In addition, CNC bending machines are ready for quick molding, which is an unquestionable consideration when you need to bend many small batches of parts. Mainly using WC67K series sheet bending machine structure; Sds-3pb bending machine… Leer Más "WC67K series WC67K series sheet bending machine

160T3200 Bending machine folded out of the middle of the plate is bent R Angle, generally related to the thickness of the plate. If you exceed the technical requirements marked by the middle of the curve, the professional term is folded out of the product straightness does not meet the requirements. The following methods are for reference: 1. It may be caused by the uneven upper and lower knives, and the included Angle of the mold is offset, so the… Leer Más "160T3200 Bending machine folded out of the middle of the plate is bent R Angle, generally related to the thickness of the plate
