Description
Technical field
The invention belongs to mould and bending field, specifically, relate to a kind of bending machine die, more particularly, it relates to a kind of
The bending machine die of nine folding workpiece.
Background technology
Bending machine die is the bender instrument for machine-shaping plate, and this instrument is made up of various parts, different moulds
The part constituted is different.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.At bender
Make blank become by the guiding each other of upper die of bending machine and lower mold under the effect of pressure and have the workpiece of given shape and size.In reality
In the production process of border, enterprise can be according to shaping workpiece shape or the difference of size, the lower mold of differently configured FLUTE ANGLE.But with
Expanding economy, the shape of the workpiece of bending is more and more diversified, and the most different workpiece is accomplished by certain moduli tool
Processing, especially need variously-shaped workpiece in Electric Appliance Cabinet, the designer of present Electric Appliance Cabinet invention when designing workpiece has
The workpiece of a kind of shape needs especially, but the workpiece of this shape is given mould factory and added man-hour, and mould factory finds that difficulty of processing is big,
Especially not knowing how to use bender to process, designing although result in this workpiece, but the predicament that cannot process.
This workpiece is because there are nine sections, so referred to as nine folding workpiece, its shape as it is shown in figure 1, this workpiece is formed successively by a sheet metal bending,
According to the shape after bending, it is passed through and is divided into workpiece first paragraph 101, workpiece second segment 102, work by we
Part the 3rd section 103, workpiece the 4th section 104, workpiece the 5th section 105, workpiece the 6th section 106, workpiece the 7th section 107, workpiece the 8th
Section 108 and workpiece the 9th section 109.Angle between workpiece first paragraph 101 and workpiece second segment 102 is 0 °, workpiece second segment 102
With the angle between workpiece the 3rd section 103, workpiece the 3rd section 103 and workpiece the 4th section 104 is all 90 °, the 4th section of 104 Hes of workpiece
Angle between workpiece the 5th section 105 is 0 °, and the length that workpiece the 4th section 104 and workpiece are the 5th section 105 is identical, workpiece the 5th section
105 and workpiece the 6th section 106, workpiece the 6th section 106 and workpiece the 7th section 107, workpiece the 7th section 107 and workpiece the 8th section 108,
Angle between workpiece the 8th section 108 and workpiece the 9th section 109 is all 90 °；Wherein workpiece is close to workpiece the 3rd section for the 6th section 106
On 103, workpiece the 7th section 107 is parallel with workpiece second segment 102；Workpiece the 6th section 106 and the length sum etc. of workpiece the 8th section 108
In the length of workpiece the 3rd section 103, the length sum of workpiece the 7th section 107 and workpiece the 9th section 109 is equal to workpiece second segment 102
Length；Workpiece is sandwiched between workpiece first paragraph 101 and workpiece second segment 102 for the 9th section 109.For so complicated workpiece, general
Logical Bending Mould is difficult to accomplish whom the most first rolls over, whom rolls over afterwards？Their bending sequentially and is the most reasonably dodged, this
It it is all a problem allowing those skilled in the art have a headache.And existing bending machine die is all from considering that one angle of folding considers
Problem, seldom has and considers that the mould processing workpiece occurs from the overall situation.
