Abstract
The invention discloses an assembly fixture for a magnetic yoke device of an electromagnetic lock. Forming grooves/groove are/is respectively formed in the bottom face of an upper die body and/or the top face of a lower die body; the wall face of each forming groove is a limiting circumferential face, and the bottom face of each forming groove is an extrusion forming face. When the assembly fixture is used, after the to-be-formed end of a to-be-assembled magnetic yoke device preassembled together is inserted into the forming grooves/groove, the upper die body and the lower die body are buckled and pressed; under the mutual extrusion action of the upper die body and the lower die body, the opening of the to-be-formed end at which a magnetic yoke sleeve is located is changed in pressure to enable the magnetic yoke sleeve to be compressed on the extrusion forming face; meanwhile, the peripheral face of the magnetic yoke sleeve located at the to-be-formed end is retrained by the limiting circumferential face, therefore, along with continuously pressing the upper die body and the lower die body, the magnetic yoke sleeve can be folded inwards on the extrusion forming face so as to form an edge covering structure at the to-be-formed end of the to-be-assembled magnetic yoke device to realize edge covering and pressing assembly on the magnetic yoke device, and therefore the assembly process of the magnetic yoke device is time-saving and labor-saving.

Detailed description of the invention
The embodiment of the assembly tooling of electromagnetic lock magnet yoke device in the present invention: as shown in Figures 3 to 6, this assembly tooling is the pressing and forming frock of a kind of electromagnetic lock yoke assembling, by upper die body 21, die sleeve 22 and lower mold body 23 are formed, upper die body 21 and lower mold body 23 are up-thin-low-thick cylinder of topping bar, the lower surface of upper die body 21 offers and is in geometric center position and the coaxial upper forming tank 211 arranged, the upper surface of lower mold body 23 offers and is in geometric center position and coaxially arranged compacted under groove 231, the trough wall surface of upper forming tank 211 and compacted under groove 231 is the external diameter spacing side face equal with the external diameter that the yoke of magnet yoke device is overlapped, the groove bottom of upper forming tank 211 and compacted under groove 231 is to draw in gradually along groove depth direction and to be squeezed into profile with coaxial conical of corresponding die body.
The outer peripheral face of upper die body 21 hypomere and the outer peripheral face of lower mold body 23 epimere are isometrical guiding side face, and this guiding side face is coaxially arranged with corresponding forming tank.Upper and lower section of intermediate location of lower mold body 23 is provided with the block shoulder 233 of projection on guiding side face periphery, and the transition portion of upper and lower section of upper die body 21 is provided with tapered frustum section from bottom to top.Die sleeve 2 is for having the hollow metal ring of certain internal-and external diameter and height, and can ensure the assembling of patrix, yoke and counterdie on the same axis, after ensureing assembling pressing, good looking appearance also meets technical requirement.
The hypomere of lower mold body 23 offers the wire hole 232 of the through groove bottom of compacted under groove 231 and the outer peripheral face of hypomere, this wire hole 232 define for lead-out wire pass from the hypomere of lower mold body 23 keep away line chamber, the aperture, two ends of wire hole 232 is in the hypomere outer peripheral face of lower mold body 23 and the groove bottom of forming tank respectively, and the trough wall surface interval of the aperture be in the groove bottom of forming tank and forming tank is arranged.
The epimere of upper die body 21 is the effort handle 212 coaxially arranged with hypomere, and effort handle 212 is the cylinder of upper downward-extension.
In the present embodiment, frock is the pre-pressing frock of the magnet yoke device be fitted together in advance being carried out to pressing, and the assembling of magnet yoke device needs pre-pressing frock and whole pressing tool successively to act on enforcement, the difference of the structure of whole pressing tool and the structure of pre-pressing frock is: the angle of inclination being squeezed into profile of whole pressing tool is less than the angle of inclination being squeezed into profile of pre-pressing frock.
In the present embodiment, the operation principle of frock is as follows: preformed press-fits the stage: first use preformed frock.Concrete using method is: be 1. vertically enclosed within the epimere periphery of lower mold body 23 by die sleeve 22; 2. yoke assembling is tentatively combined; 3. die sleeve 22 is put in the yoke assembling after preliminary combination, make it and be squeezed into profile and contact, attention pulls out lead-out wire from through wires hole; 4. upper die body 21 is put into the upper end of die sleeve 22, (being squeezed into profile contact yoke fit on edge of patrix); 5. pressure is applied to upper die body 21.By above-mentioned five steps, pre-pressing can be assembled to yoke, make the pre-flanging of yoke.This process, for can realize pre-pressing, can make yoke flanging to certain angle.
Final shaping unit press-fits the stage: after press-fiting in advance, recycles whole pressing tool.Concrete operation step is similar to pre-pressing, the assembling of electromagnetic lock yoke can be press fit into promising result after using final shaping unit frock like this.
In the above-described embodiments, in bonding processes, avoid lead-out wire to interfere the line chamber of keeping away of the edge turnover distortion of yoke cover to be wire hole, in other embodiments, the escape groove that this wire hole also can be arranged with the bottom land of forming tank is replaced, in addition, when not considering that the turnover of lead-out wire to yoke cover edge is out of shape, can this not being set on die body yet and keeping away line chamber.
In the above-described embodiments, the groove bottom of forming tank is the conical surface, and in other embodiments, the groove bottom of this forming tank also can be plane, the edge that yoke is overlapped directly can be turned down on the end face of magnet yoke device like this.
