The specific structural characteristics and use of the bending machine play a role
The bending machine is widely used, and it can come in handy in many fields. The main reason for this is because the structural characteristics of the bending machine are relatively special, and the special structural characteristics lead to its many functions. Next, world press machine will lead you to take a brief look at the specific structural characteristics of the bending machine.
This kind of CNC bending machine for bending thin plates. The CNC bending machine includes a bracket, a worktable and a clamping plate. When in use, the coil is energized by the wire, and after the electricity is energized, the pressure plate is gravitationalized, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressing plate can be made into various workpiece requirements, and the workpiece with side walls can be processed, and the operation is also very simple.
To make a brief introduction according to the CNC bending machine processing Q235 sheet, the first is to turn on the power, turn on the switch on the control panel, and then start the oil pump, so that you can hear the rotation of the oil pump, and the machine does not move at this time. Stroke adjustment, you must pay attention to adjusting the stroke when using it, and you must test it before bending. When its upper die goes down to the bottom, there must be a gap of plate thickness. Otherwise, it will cause damage to the mold machine. The adjustment of the stroke is also electric quick adjustment.
For the selection of the bending notch, it is generally necessary to select a notch with a width of eight times the thickness of the plate. For bending 4mm sheet, you need to choose a notch of about 32. The rear gauge adjustment generally has electric quick adjustment and manual fine adjustment, the method is the same as that of the shearing machine.
Step on the foot switch to start bending, the CNC bending machine mold of Kuaiwei machine tool is different from the shearing machine, you can release it at any time. CNC bending machine, hemming machine, CNC bending machine mold, sheet bending Plastic sheet is directly bent, no splicing, no slotting, no welding rod, its corner appearance is beautiful and watertight, it will be welded by hand The transformation into fully automatic machine operation improves quality, improves labor efficiency, reduces labor costs, and greatly shortens the production cycle of products. Fully automatic plastic folding machine is a fully automatic mechanical equipment with electrical integration.
It is developed according to the principle of heating, softening, melting and welding of plastic plates. It is suitable for the corners of all thermoplastic materials. The speed is fast, the corners are treated with beautiful surface, and the strength is high. Hydraulic shears are divided into pendulum type and gate type. Because the pendulum activated carbon moves in an arc, and the arc blade is very difficult to make, it is usually compensated with a horn after the blade, so the obtained gap is not accurate, and the cut sheet is not very ideal.
Because of the arc motion, the blade cannot be made into a rectangle, but should be made into an acute angle, so the force of the blade is not ideal, and the blade damage is also severe. The domestic representatives of the pendulum shearing machine are Tianshui Machine Tool Factory and Chong. Shearing Machine Factory. The gate type hydraulic shearing machine has overcome all the above problems, but at present, there are not many domestic manufacturers that can make the gate type shearing machine.
Compared with the shearing machine, the technical content of the CNC bending machine is slightly higher. .At present, G-shaped and F-shaped are common in China. The F-shaped should be a traditional domestic product. It uses a built-in adjustable mechanical stop for positioning. Because it is a built-in type, its anti-eccentric load capacity is quite weak, so there are Huangshi has a balance valve in the early CNC bending machine mold, but due to the hydraulic pressure, it is too complicated, which brings serious problems to the later maintenance and stability.
The latter is the G-type after the improvement of the F-type model. It adopts the mechanical positioning of the outer slide plate. Compared with the F-type, it is simpler and more convenient to debug. Personnel shims solved the problem.
have manifold mechanical power press effects, ranging from automatic power press machine to automatic power press machine.
You can find a large selection of quality at World Press Machine. Go get your desired one.
There are so many factors that businesses have to weigh when producing mechanical power press, and we are not going to pretend to grasp all of them.
Equipping mechanical power press with innovative technology and updated processes will simplify daily compliance duties so that they can focus on attracting, retaining, and developing the most engaged workforce possible.
