Description
Technical field
The present invention relates to mould and brake techniques field, more particularly, it relates to the processing method of a kind of doorjamb Bending Mould.
Background technology
Bending machine die is the bender instrument for machine-shaping plate, and this instrument is made up of various parts, and the part that different moulds is constituted is different, and it mainly realizes the processing of article profile by the change of institute's moulding material physical state.Blank is made to become the workpiece having given shape and size by upper die of bending machine and guiding each other of lower mold under the effect of bender pressure.In actual production process, enterprise can be according to shaping workpiece shape or the difference of size, the lower mold of differently configured FLUTE ANGLE.But being as expanding economy, the shape of the workpiece of bending is more and more diversified, the most different workpiece is accomplished by certain moduli tool and processes, and especially needs variously-shaped doorjamb in antitheft door.Present antitheft door is not merely to make an issue of on lockset, also it is necessary to have certain anti-pry open performance in the design of doorframe, so could meet security requirement.
Designer has invented a kind of security door frame shape when designing workpiece, this doorjamb is not only combined with door leaf tightly, and soundproof effect is good, but the workpiece of this shape is given mould factory and is added man-hour, mould factory finds that difficulty of processing is big, traditional compressing is not suitable for this workpiece, does not knows again how to use bender to be processed, although result in this workpiece to design, but the predicament that cannot process occurs.This doorjamb structure is as shown in Figure 1, this doorjamb is made up of multiple right angles section, flanging projection 1-5, the section of being folded flat 1-7 and changeover portion 1-7-1, its each right angle section forms the basic structure of doorjamb, its flanging projection 1-5 is used for making door leaf engage with doorjamb tightly, there is tamper-resistant function, its section of being folded flat 1-7 and changeover portion 1-7-1 then may further ensure that fitting tightly between the two, and soundproof effect is preferable.This doorjamb is it may appear that the simplest, but but there is great difficulty in its size Control and structure processing, the especially processing of the changeover portion 1-7-1 on flanging projection 1-5, the section of being folded flat 1-7, because the size of flanging projection 1-5 is less, it is in again the centre position of entirety, adds the impact being vulnerable to other limits man-hour；Same, single being folded flat is easy to processing, if to fold changeover portion 1-7-1 on the section of being folded flat 1-7 again, this has the biggest difficulty.In addition, the processing sequence of this doorjamb total the most just can accomplish reasonably to dodge, and how to ensure the uniformity of size, and these problems make enterprise more have a headache, being allowed to feel frustrated, envying that this doorjamb structure ingenious does not the most process can the mould of employing.Therefore it provides the development important in inhibiting that a set of effective processing scheme is to this doorjamb and this field.
Through retrieval, technical scheme about doorjamb bending is disclosed, such as: Chinese Patent Application No.: 200710112952.2, the applying date: on September 19th, 2007, invention and created name is: anti-theft gate rabbet, its manufacture method and particular manufacturing craft thereof, rabbet in this application case is integrally to be bent into inside to have the structure of L-type cavity by metallic plate, metallic plate includes the first frame, second frame, 3rd frame, 4th frame, 5th frame and the 6th frame six part, between adjacent frame, bending is arranged, connect between 6th frame and the first frame, its special Bending Mould is relatively common, simply conventional orthogonal Bending Mould is slightly modified, and rabbet is simple, either door rabbet or its processing mold all can not embody its creativeness.
