Description
Patent application of the present invention is to be for application number: the divisional application of 201410819761X, and the applying date of original application is:2014-12-24, invention and created name is: a kind of doorjamb, doorjamb Bending Mould and bending method.
Technical field
The present invention relates to mould and bending technical field, more particularly, relate to a kind of doorjamb bending method.
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 parts, different mouldsThe part difference forming, it mainly realizes the processing of article profile by the change of institute's moulding material physical state. At benderUnder the effect of pressure, by the guiding each other of upper die of bending machine and counterdie, blank is become and have the workpiece of given shape and size. In realityIn the production process of border, enterprise can, according to the difference of shaping workpiece shape or size, configure the counterdie of different groove angles. But withExpanding economy, the shape of the workpiece of the bending of is also more and more diversified, and different like this workpiece just needs special mouldProcess, especially in antitheft door, need the doorjamb of various shapes. Present antitheft door is not merely to make an issue of on lockset,In the design of doorframe, also must there is certain anti-performance of prying open, could meet like this security requirement.
Designer has invented a kind of security door frame shape in the time of design workpiece, and this doorjamb is not only combined with door leaf tightly,And soundproof effect is good, but the workpiece of this shape give mould factory and add man-hour, mould factory finds large, the traditional pressure of difficulty of processingThe type of making is not suitable for this workpiece, does not know again how to use bender to process, although cause this workpiece to design,But there is the predicament that cannot process. This doorjamb structure as shown in Figure 1, this doorjamb by multiple right angles section, flanging projection 1-5,The section of being folded flat 1-7 and changeover portion 1-7-1 composition, its each right angle section forms the basic structure of doorjamb, and its flanging projection 1-5 usesIn door leaf is engaged tightly with doorjamb, there is tamper-resistant function, its section of being folded flat 1-7 and changeover portion 1-7-1 can be furtherEnsure fitting tightly between the two, soundproof effect is better. It is very simple that this doorjamb may seem, but its size Control andIn structure processing, but there is great difficulty, the especially processing of the changeover portion 1-7-1 on flanging projection 1-5, the section of being folded flat 1-7, because ofFor the size of flanging projection 1-5 is less, again in overall centre position, add the impact that is vulnerable to other limits man-hour; Same,Single being folded flat is easy to processing, if fold changeover portion 1-7-1 on the section of being folded flat 1-7, this has very large difficulty again. ThisOutward, how the processing sequence of this doorjamb total just can accomplish is reasonably dodged, and how to ensure the uniformity of size, theseProblem makes enterprise comparatively have a headache, and makes it to feel frustrated, and envies that the ingenious of this doorjamb structure but do not have processing to adoptWith mould. Therefore, provide the development important in inhibiting of a set of effective processing scheme to this doorjamb and this field.
Through retrieval, existing open about the technical scheme of doorjamb bending, for example: 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 andIts particular manufacturing craft, the rabbet in this application case is the structure that is bent into inside and is had L-type cavity by metallic plate one, metallic plate bagDraw together the first frame, the second frame, the 3rd frame, the 4th frame, the 5th frame and hexagon frame six parts, adjacent frame itBetween bending arrange, between hexagon frame and the first frame, be connected, its special Bending Mould is comparatively common, is traditional right-angle bendingMould slightly improves, and rabbet is simple, is that a rabbet or its processing mold all can not embody its creativeness.
