Description

A kind of processing method of doorjamb Bending Mould
Technical field
The present invention relates to mould and brake techniques field, more particularly, relate to a kind of processing method of doorjamb Bending Mould.
Background technology
Bending machine die is that bender is used for the instrument of machine-shaping plate, and this instrument is made up of various part, and the part that different moulds is formed is different, and it realizes the processing of article profile mainly through the change of institute's moulding material physical state.Under the effect of bender pressure, by the guiding each other of upper die of bending machine and counterdie, blank is become have the workpiece of given shape and size.In actual production process, enterprise according to the difference of shaping workpiece shape or size, can configure the counterdie of different FLUTE ANGLE.But along with expanding economy, want the shape of the workpiece of bending also more and more diversified, workpiece different so just needs certain moduli tool to process, and especially needs the doorjamb of various shape in antitheft door.Present antitheft door is not merely make an issue of on lockset, the design of doorframe also must have certain anti-ly pry open performance, could meet security requirement like this.
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 large, traditional is not compressingly suitable for this workpiece, does not know again how to use bender to process, although result in this workpiece to design, there is the predicament that cannot process.This doorjamb structure as shown in Figure 1, this doorjamb is made up of multiple right angles section, flanging protruding 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, the protruding 1-5 of its flanging is used for door leaf is engaged with doorjamb tightly, there is tamper-resistant function, its section of being folded flat 1-7 and changeover portion 1-7-1 then can ensure fitting tightly between the two further, and soundproof effect is better.This doorjamb may seem very simple, but its size Control and structure processing but there are great difficulty, the processing of the changeover portion 1-7-1 especially on flanging protruding 1-5, the section of being folded flat 1-7, because the size of the protruding 1-5 of flanging is less, be in again overall centre position, add the impact being vulnerable to other limits man-hour; Same, single being folded flat is easy to processing, if will fold changeover portion 1-7-1 again on the section of being folded flat 1-7, this has very large difficulty.In addition, how the processing sequence of this doorjamb total just can accomplish reasonably to dodge, and how to ensure the uniformity of size, these problems make enterprise comparatively have a headache, make it to feel frustrated, that envies this doorjamb structure does not ingeniously but have processing can the mould of employing.Therefore, provide a set of effective processing scheme to the development important in inhibiting in this doorjamb and this field.
Through retrieval, technical scheme about doorjamb bending is existing open, 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 bent into by metallic plate the structure that inside has L-type cavity, metallic plate comprises the first frame, second frame, 3rd frame, 4th frame, 5th frame and hexagon frame six part, between adjacent frame, bending is arranged, be connected between hexagon frame with the first frame, its special Bending Mould is comparatively common, just conventional orthogonal Bending Mould slightly improves, and rabbet is simple, that a rabbet or its processing mold all can not embody its creativeness.
