Description
Technical field
The present invention relates to the hot stamping die technical field, specifically is a kind of nut hot stamping die.
Background technology
There is a kind of nut to be called as interior attaching nut at present; Should interior attaching nut belong to hex nut; The employing copper rod is raw material, adds need carry out operations such as blank, punching, cutting and fine finishining man-hour, and this processing mode is loaded down with trivial details, raw materials consumption is big, production efficiency is low; Processing is simple, raw material are economized, advantage of high production efficiency and the nut hot stamping die has, but do not see at present be useful on produce said in attaching nut's nut hot stamping die.
Summary of the invention
The technical problem that the present invention will solve is that a kind of nut hot stamping die that is used to produce interior attaching nut is provided.
Technical scheme of the present invention is; Nut hot stamping die of the present invention; It comprises die shank, cope match-plate pattern, upper die plate, upper mounted plate, rubber blanket, take off the backing strap plate, be provided with upper mold core upper mold core fixed head, lower bolster, counterdie backing plate, bottom plate, be provided with the lower die-sleeve of lower mold core; Said cope match-plate pattern, upper die plate, upper mounted plate, rubber blanket, take off backing strap plate, upper mold core fixed head and connect in regular turn from top to bottom; Said lower bolster, counterdie backing plate, bottom plate, lower die-sleeve connect from bottom to top in regular turn, and said upper mold core is provided with hexagonal hole; With punch on the said hexagonal hole sliding fit one; The upper end of last punch pass take off be arranged in the upper mounted plate setting behind backing strap plate, the rubber blanket be used for said first hole of going up punch of axial limiting; Said upper end and the said first hole sliding fit of going up punch; The end face of said upper end of going up punch can with one pass die shank, upper die plate offsets with the lower surface that gets into the knock-pin in said first hole; The second hole sliding fit that the said knock-pin of the confession that is provided with in said knock-pin and die shank, the upper die plate passes, the said punch lower end of going up is provided with pilot hole and first forming ends that is used for the first sphere end of moulding nut from top to bottom in regular turn; Said lower mold core is provided with second forming ends of the second sphere end that is used for the moulding nut, pass second forming ends of said lower mold core outer and with the coaxial counterdie positioning guide column of lower mold core by reference column be molded over the reference column top and can constitute with said pilot hole sliding fit and diameter lead less than reference column.
Operation principle of the present invention is, adopts copper pipe as raw material, said cope match-plate pattern, upper die plate, upper mounted plate, rubber blanket, takes off backing strap plate, upper mold core fixed head and is connected to form the part of the upper die from top to bottom in regular turn; Said lower bolster, counterdie backing plate, bottom plate, lower die-sleeve are connected to form the part of the lower die from bottom to top in regular turn, add man-hour, at first copper pipe are enclosed within the copper pipe bottom is dropped on second forming ends of lower mold core; Then, part of the upper die and part of the lower die matched moulds, the lead on counterdie positioning guide column top partly slides in the pilot hole; The copper pipe top is introduced into first forming ends of punch lower end and then promotes to go up punch and moves up to top dead centre; And rubber blanket is compressed in the matched moulds process, make take off the backing strap plate, the upper mold core fixed head can move upward in the matched moulds process always, last punch stop to move upward the back matched moulds will continue; Copper pipe also will be by further extruding; In the forming cavity that first forming ends, hexagonal hole, second forming ends, counterdie positioning guide column form, it is required form that copper pipe is extruded moulding like this, promptly interior attaching nut; After the die sinking; Knock-pin pushes punch, and last punch is got product, thereby accomplishes product stripping.
After adopting said structure; The present invention compared with prior art; Have the following advantages: combine technique scheme and operation principle to know; Attaching nut's drop stamping moulding in the mutual cooperation of each parts can realize, and the processing that is had except that the nut hot stamping die with prior art is simple, raw material are economized, the advantage of high production efficiency, also have compact conformation, simple and reliable advantage.
