Abstract

A Combined bending mould, it is characterized in that it comprise fix a cutting tool, middle cutter mould, bottom tool mould, equipment bed die; Wherein said fixing a cutting tool is fixed on the upper fixture of bending equipment, can with upper fixture, move up and down individually, also can move up and down together with middle cutter mould two parts, also can move up and down together with middle cutter mould, bottom tool mould three parts; Its method of work is: start bending equipment, install cutter, middle cutter mould and bottom tool mould, process lamp bending fork and clap curved; Superiority is: simple in structure, practical, and simple process, production cost is low, and machining accuracy is higher, easy to use, and production efficiency improves greatly, will save suitable processing cost.

Description

A kind of Combined bending mould

(1) technical field:

The present invention relates to a kind of fire resistance steel door, Anti-theft door made of steel, common steel door and make the processing mold that door face board is used, it is a set of knockdown processing mold, can in process, remove frequent replacing cutter and counterdie from, disposablely simply labyrinth is shaped, enhance productivity significantly.

(2) background technology:

On the fire resistance steel door of selling in the market, Anti-theft door made of steel, common steel door leaf, be provided with for blocking the gear seam bar structure of crack between a door and its frame, when processing and fabricating gear seam bar structure, need frequently more mold exchange and cutter, under normal circumstances, shown in machining steel door shield seam bar (seeing Fig. 2), processing local 5 is pedaled fork and need to be changed when curved and fix a cutting tool for 2 times and 3 counterdies, lost time about 120min; Processing local 6 is clapped and need to be changed and fix a cutting tool for 2 times and 2 counterdies when curved, and lost time, about 80min, needed 200min lost time altogether, and suitable takes a lot of work.

The utility model-a kind of Combined bending mould has solved the time-consuming problem of above-mentioned existence preferably, install this set of Combined bending mould, need not change frequently again cutter and mould, disposable complicated gear seam bar is shaped, approximately need 40min lost time, be above-mentioned processing need lost time 1/5, shortened process time widely, improved production efficiency.

(3) summary of the invention:

The purpose of this utility model is to design a kind of Combined bending mould, it has solved the time-consuming problem of current existence preferably, install this set of Combined bending mould, need not change frequently again cutter and mould, disposable complicated gear seam bar is shaped, shorten process time widely, improved production efficiency.

The technical solution of the utility model: a kind of Combined bending mould, it is characterized in that it comprise fix a cutting tool, middle cutter mould, bottom tool mould, equipment bed die; Described fixing a cutting tool is directly fixed on the upper fixture of bending equipment; Respectively there are two screwed holes at described middle cutter mould two ends, load onto four bolts, can middle cutter mould be connected with equal-height position hook in fixture two ends on bending equipment with four isometric draw rings; Respectively there are two screwed holes at described bottom tool mould two ends, load onto four bolts, can bottom tool mould be connected with equal-height position hook in fixture two ends on bending equipment with four isometric draw rings; Described equipment bed die belongs to a part for bending equipment, plane and maintaining static.

Described fixing a cutting tool is fixed on the upper fixture of bending equipment, can with upper fixture, move up and down separately, also can move up and down together with middle cutter mould two parts, also can operation up and down together with middle cutter mould, bottom tool mould three parts.

With described, fix a cutting tool with middle cutter mould two parts as patrix, described bottom tool mould, as counterdie, once just can machine and pedal the curved left-half of fork; With described fixing a cutting tool as patrix, described middle cutter mould, as counterdie, once just can machine and pedal the curved right half part of fork; Then with described fixing a cutting tool as patrix, described middle cutter mould is as counterdie, the curved wedge angle that processes of first clapping; Then with described, fix a cutting tool with middle cutter mould, bottom tool mould three parts as patrix, described equipment bed die is as counterdie, curved the machining of clapping.

All above-mentioned content of operation, only need simply by the isometric draw ring dismounting of coupling type, operate suitable facility.

Work engineering of the present utility model is: (1) starts bending equipment, installs cutter; (2) middle cutter mould is placed on equipment bed die together with bottom tool mould, and adjusts position accurately, require the nose center line of fixing a cutting tool to overlap with the center line of groove under middle cutter mould; (3) with four isometric draw rings, middle cutter mould is connected with equal-height position hook in fixture two ends on bending equipment, sheet metal to be processed is placed between middle cutter mould and bottom tool mould, operation bending equipment, completes the left-half processing of lamp bending fork; (4) pull down four isometric draw rings, sheet metal to be processed be placed on fix a cutting tool and middle cutter mould between, operation bending equipment, completes the right half part processing of lamp bending fork; (5) sheet metal to be processed be placed on fix a cutting tool and middle cutter mould between, operation bending equipment, the curved wedge angle that processes of first clapping; (6) hang up isometric draw ring, sheet metal to be processed is placed between bottom tool mould and equipment bed die, operation bending equipment, completes the curved processing of clapping.

Superiority of the present utility model is: (1) this apparatus structure is simple, practical; (2) this device technique is easy, easily makes, and production cost is very low; (3) this device is only installed and is adjusted once, has avoided repeatedly installing and adjusting the mismachining tolerance producing, and relatively easy, machining accuracy is higher; 4) this device is easy to use, and production efficiency can improve greatly, will save sizable processing cost.
