A CNC sheet metal bending machine with streamlined design, high speed, high precision, and high rigidity.
Electro hydraulic servo system, fully closed-loop control slider synchronization.
The hydraulic disturbance compensation and throat deformation compensation mechanism of the workbench ensures the bending depth and accuracy.
The rear material is driven by a digital AC servo motor and driven by a large lead precision ball screw.
The WE67K export electro-hydraulic synchronous hydraulic CNC bending machine adopts BoSH high-performance integrated servo control system for oil cylinder synchronization, combined with international standard grating ruler, to form a fully closed-loop control, improve the stability of machine tool operation, simplify pipelines, and prevent leakage.
The WE67K export electro-hydraulic synchronous hydraulic CNC bending machine adopts a hydraulic convex automatic deflection compensation mechanism to solve the influence of the deformation of the slider on the quality of the workpiece during the bending process. The compensation amount is automatically adjusted by the CNC system, which is convenient and accurate. Ensured the straightness and bending angle of the bent workpiece.

Numerical control bending machine is a machine tool with two-dimensional product graphic editing, which has better performance than ordinary hydraulic bending machine in the actual production process. The programming methods used are summarized as follows. UN: Select the corresponding lower mold from memory for processing material MA: Select the type of processing plate (1: steel; 5: other materials) Thickness TH: Processing plate thickness Length BL: Processing plate width Bending method BM: Bending method Bottom bending 10=Flattening bending 11=Flattening bottom bending) Correction: Ca=Correction of bending angle axis value (for a certain angle) Pressure: P=Programming position of the output tonnage rear material during bending Opening height: y=Opening height of the slider, height of speed conversion. Speed: S=bending speed Delay time: T=holding time at the bending point 2.2 Mold shape of CNC bending machine The mold shape of CNC bending machine is shown in Figure 2 (a) (b). The (a) and (b) in the middle are segmented cutting tools (upper and lower molds), which are suitable for processing various sheet metal parts and can handle complex parts with multiple bending surfaces that traditional bending tools cannot process. The segmented structure of the cutting tool is reasonable, easy to operate, low manufacturing cost, easy to disassemble and assemble during the processing, simple to maintain, safe and reliable. For the segmented tool base, 4 is the segmented tool positioning block, and 5 is the bending machine tool holder.
The working principle of CNC bending machine and the working process of CNC bending machine for machining parts are shown in the figure. (1) Write programs in the prescribed code program format based on the drawings and process plans of the processed parts. (2) The program is input into the numerical control device (CNC) of the machine tool. (3) After the numerical control device translates and calculates the program, the mold is replaced according to the programming. (4) Process qualified parts on the machine tool. 2.1 Numerical Control Bending Machine Programming Main Parameters NCP50-15DA65 Numerical Control Bending Machine is a metal sheet cold processing forming machine. The bed is made of all steel welded structure, with a nominal pressure of 500KN, a worktable length of 1550mm, a throat depth of 300mm, an opening height of 370mm, a slider stroke of 180mm 120mm/s, a slider stroke of 10mm/s, a slider return of 100mm/s, a main motor power of 4kw, and an oil tank capacity of 120L. 2.3 Sectional dimensions of segmented cutting tools for attached bending machines.
In modern times
CNC bendingThe reliability of CNC systems is increasing, and the failures of CNC systems themselves are also decreasing. External failures of CNC equipment can be divided into software failures and hardware failures caused by external hardware damage. Software failures refer to failures caused by improper operation, adjustment, and handling, which often occur in the early stages of equipment use or during the adjustment period of equipment users. However, deep maintenance of CNC machine tools occurs when the machine tool malfunctions. The maintenance work of enterprises not only considers the restoration of CNC machine tool functions, but also comprehensively considers the causes of the fault and the most economical maintenance plan for fault handling.
At present, there are three main forms of business in the domestic CNC bending machine maintenance and renovation industry, namely order based maintenance and renovation, equipment maintenance, and recycling of used machine tools for remanufacturing. Among these three business forms, the most common and widespread is order based maintenance and renovation.
