Description
Technical field
The utility model belongs to mould applications, relates to the punch die auxiliary, specifically a kind of Wedge mechanism of forcing return facilities that has.
Background technology
Mould is the oblique motion that vertical moving up and down is converted into certain angle with Wedge mechanism; After accomplishing oblique processing tasks; The wedge slide block need rely on spring to make it get back to original position; Spring has certain service life, if spring failure, Wedge mechanism just can not be got back to the precalculated position after work is accomplished.
The assembly of present pressure backhaul mainly comprises two kinds of hook-shaped and plate shapes; These two kinds both sides of forcing the backhaul assembly to be installed on the wedge slide block; Can play certain pressure backhaul effect; But space hold is bigger in wedge slide block both sides owing to it, and mechanism is huge relatively, also influences the intensity of circumferential component simultaneously; In addition, force backhaul assembly buying expenseses higher as these two kinds, Installation and Debugging are complicated, and the contact area of itself and fixed block is little, and the assembly holding capacity is bigger.
The patent No. is 2010206847678 Chinese utility model patent, discloses a kind of " lifting wedge dual spring parallel connection Wedge mechanism ", and that's about the size of it for existing pressure backhaul element structure, and it mainly is made up of drive block, slide block, take-up housing; Slide block is installed on the take-up housing, and the side that slide block is installed cooperates the backhaul effect of forcing of playing with drive block.This constructed products element structure is complicated, process and assemble is difficult, and it is big to take up room, and is difficult for debugging.
The utility model content
The technical problem that the utility model will solve provides a kind of Wedge mechanism of forcing return facilities that has, and main dependence forces backhaul piece and fixed block to form the pressure return facilities; Wherein force the backhaul piece to be installed in wedge slide block rear side; Fixed block is installed on the mount pad, and both are bevel angle and cooperate, and the mating surface angle is consistent with wedge backhaul angle; Be convenient to equidirectional backhaul; Through the open and close movement up and down of wedge, change the angular movement of backhaul assembly into during work, and then accomplish the pressure backhaul of wedge.The side space that this product has been saved wedge than prior art, simple in structure, be convenient to processing and assembling.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of Wedge mechanism of forcing return facilities that has comprises wedge slide block, mount pad, has guide plate on the mount pad, has a left side right-oblique guiding surface down on the guide plate, and its special feature is: said pressure return facilities comprises forces backhaul piece, fixed block;
Corresponding to the place, below in return spring hole, have the in-line groove of level on the said wedge slide block rear end face;
The cross section of said pressure backhaul piece is similar z shape, and its left part is and 7 suitable fonts of wedge slide block rear end face bottom, and wherein i.e. left the convexity in the top of 7 fonts is stuck in the in-line groove; The bottom of its right part has forces backhaul piece inclined-plane, and this inclined-plane is a right bank under the last left side, on connect vertical plane;
Fixed block is fixed on the mount pad, and its lower left quarter has the fixed block inclined-plane, and this inclined-plane is a right bank under the last left side, on connect vertical plane;
Force backhaul piece inclined-plane to contact with the fixed block inclined-plane.
More than be the basic structure of the utility model; The wedge slide block is installed in upper bolster, follows press ram and does and move both vertically, and forces the backhaul piece to be installed in the rear side of wedge slide block; The wedge mount pad is installed on the die shoe of mould, and fixed block is installed in the rear side of mount pad.Wedge slide block and mount pad interact through guide plate, and when spring members lost efficacy, pressure backhaul piece can drive the wedge slide block and move upward along the inclined-plane of fixed block and break away from work fully until workpiece.The pressure backhaul piece of the utility model is installed on the slide block rear side, and volume own is little, has saved the space of both sides; It is simple in structure in addition, is convenient to processing, assembling and setting, and also contact area is big, and stressed good.
As a kind of optimization of the utility model, the slope on said guiding surface, pressure backhaul piece inclined-plane, fixed block inclined-plane is identical; Force backhaul piece inclined-plane and fixed block inclined-plane to be slidingly matched.
A kind of qualification as the utility model has the beveled guide block on the said guide plate, the lower left side of wedge slide block is the slipping block that is slidingly fitted with the beveled guide block.
Another kind as the utility model limits, and said wedge slide block is positioned upper mould, and its front lower ends has the die work parts; Holder is positioned lower mould.
Owing to adopted above-mentioned technical scheme, the acquisition of technology progress of the utility model institute is:
(1) satisfies the purpose of forcing backhaul, practice thrift the space, both sides;
(2) simple in structure, Installation and Debugging are easy, and processing mode and technology are simple
(3) contact area is big, and is stressed fine.
The utility model is applicable to various diels, when return spring lost efficacy, can realize forcing return.
The utility model below will combine Figure of description and specific embodiment to do further explain.
