Anti-theft gate rabbet, its production method and its special mould

Abstract

The utility model discloses a notch of an anti-burglary door, a manufacture method of the notch and a dedicated mould of the notch. The notch is made by bending a mental sheet in an integrated way and the inside of the notch is provided with an L-shaped cavity structure. The metal sheet comprises a first rim, a second rim, a third rim, a fourth rim, a fifth rim and a sixth rim. Every two neighboring rims are bent to make them arranged in a vertical way. The sixth rim and the first rim are connected in a fixing way. In order to manufacture the notch, the dedicated bending module is used for the utility model to make all rims forming the notch be bent and form in an integrated way. Thus, the processing procedures are reduced, the production efficiency is promoted, and the manufacture cost is reduced. Moreover, the structural intensity after the assembling is enhanced.

Description

technical field [0001] The invention relates to an anti-theft door, in particular to an anti-theft door cutout for the jointing of two anti-theft door panels. The invention also relates to a method for manufacturing the anti-theft door cutout and a special mold thereof. Background technique [0002] Rural houses generally have courtyards, and most of the courtyard walls are equipped with anti-theft doors. In the past, the iron doors were generally divided into two, and there was no occlusal part in the middle. At present, in order to prevent the anti-theft door from being damaged, some anti-theft door manufacturers have added a cut in the middle part of the two doors. If it is set up vertically, as shown in Figure 2, the sheet can only be folded into a vertical angle. If the sheet is to be made into a cutout, each part of the cutout can only be made separately, and finally welded together , the disadvantage is that there are many processes and cannot be integrally formed, w...

[0002] Rural houses generally have courtyards, and most of the courtyard walls are equipped with anti-theft doors. In the past, the iron doors were generally divided into two, and there was no occlusal part in the middle. At present, in order to prevent the anti-theft door from being damaged, some anti-theft door manufacturers have added a cut in the middle part of the two doors. If it is set up vertically, as shown in Figure 2, the sheet can only be folded into a vertical angle. If the sheet is to be made into a cutout, each part of the cutout can only be made separately, and finally welded together , the disadvantage is that there are many processes and cannot be integrally formed, which not only reduces the production efficiency, but also increases the production cost, and the structural strength after assembly is small. With the prolongation of use time, its connection parts are easy to break, rust, and even oxidize rot
