In the purchase of 30t hydraulic press brake once improper choice, production costs will rise



The 30t hydraulic press brake comprises a bracket, a table and a clamping plate, the table is arranged on the bracket, the table is composed of a base and a pressure plate, the base is connected with the clamping plate through a hinge, the base is composed of a shell, a coil and a cover plate, the coil is placed in the depression of the shell, the top of the depression is covered with a cover plate. When used, the wire is energized to the coil, and after energized, the pressure plate produces gravity, so as to achieve the clamping between the pressure plate and the base plate. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece can be processed on the side wall.


hydraulic press brake Structure and characteristics


1. All steel welded structure, with sufficient strength and rigidity.

2. Hydraulic upward transmission, the cylinder at both ends of the machine tool is placed on the slide block, and directly drives the sliding work.

3. Slider synchronization mechanism adopts torsional shaft to force synchronization.

4. Mechanical block structure, stable and reliable.

5. Quick adjustment of slider stroke, manual fine tuning, counter display.

6. Oblique wedge deflection compensation mechanism to ensure higher bending accuracy


Method of use

 DA66T Press Brake 03

According to the ordinary hydraulic bending machine processing Q235 sheet to do a simple introduction:

1. First, switch on the power supply, open the key switch on the control panel, and then press the oil pump to start, so that you can hear the rotation sound of the oil pump. (The machine does not move at this time)

2, stroke adjustment, the use of bending machine must pay attention to adjust the stroke, must be tested before bending. Bending machine die down to the bottom must ensure that there is a plate thickness clearance. Otherwise, the mold and the machine will be damaged. Stroke adjustment is also electric quick adjustment and manual fine tuning.

3, bending notch selection, generally choose the plate thickness of 8 times the width of the notch. For bending 4mm sheet metal, choose about 32 notches.

4, the rear stopper adjustment generally has electric quick adjustment and manual fine tuning, the method is the same as the shearing machine.

5, step on the foot switch to start bending, bending machine and shearing machine is different, can be loosened at any time, loosen the foot bending machine will stop, continue to step down

Correct choose and buy

In the purchase of bending machine once the choice of improper, production costs will climb, bending machine can not be expected to recover costs. Therefore, several factors need to be weighed in decision making.

 

Fold the workpiece

The first important consideration is the parts you are going to produce. The point is to buy a machine that can complete the processing tasks with the shortest worktable and the smallest tonnage.

 

Carefully consider the material grade and the maximum machining thickness and length. If the bulk of the work is low carbon steel with a thickness of 16 gauge and a maximum length of 10 feet (3.048 m), the free bending force need not be greater than 50 tons. However, if you are doing a lot of concave die forming, you may want to consider a 160 tonnage machine.

 R axis

Assuming the thickest material is 1/4 inch, 200 tons is required for 10 ft free bending and at least 600 tons for bottom die bending (corrected bending). If most of the pieces are 5 feet or less, the tonnage is almost halved, greatly reducing acquisition costs. The length of the parts is very important in determining the specifications of the new machine.

 

Folding flexible change

Under the same load, the torsion of the table and slider of the 10-foot machine is 4 times that of the 5-foot machine. This means that shorter machines require less gasket adjustment to produce acceptable parts. Reducing gasket adjustment reduces preparation time.

 

Material grade is also a key factor. Compared with mild steel, stainless steel usually requires about 50% more load, and most grades of soft aluminum reduced about 50%. You can always get the machine tonnage table from the manufacturer of the bending machine. This table shows the estimated tonnage required per foot length for different thicknesses and materials.
