Abstract
The utility model relates to a once-molding die for cutting an edge and reducing a rod for a main screw. The once-molding die comprises an upper die and a lower die. A solid die core is arranged at the bottom of the upper die, the lower die comprises a lower die casing, a pressing cover, an edge cutting die and an ejection block, wherein the edge cutting die and the ejection block are arranged in the lower die casting sequentially. The ejection block is connected with the bottom of the edge cutting die. A main screw head cavity and a rod straight end face cavity communicated with the main screw head cavity are arranged in the edge cutting die. A die releasing sleeve matched with the main screw is arranged in the ejection block. The ejection block is further provided with a hole protecting centre penetrating through the die releasing sleeve. The ejection block is connected onto the lower die casing through the pressing cover. The die releasing sleeve is connected with an ejection stick. The once-molding die saves raw materials, finishes die-stamping for straight-cutting end face and reducing rod at one time, and original four procedures are reduced to three. The once-molding die greatly improves labor production rate, saves labor and power and reduces device investment and abrasion.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to the female nail side cut of a kind of scissor body connecting screw, contracting bar one-time-shaped mould, belongs to the machine die technical field.
Background technology
The scissors that uses in the daily life comprises upper knife body, lower knife body, and upper knife body is connected the nut nail with lower knife body, the son nail connects.The processing of present this nut nail, the first step are done pre-upsetting and are processed at first with the cylindrical blank punching press; Second step is taken out centre bore; The 3rd step is by mould punching contracting bar; The 4th step is by the straight end face of the female nail of machined cutting bar section; Like this nut nail from former expect finished product, need finish through the machining operation processing of the straight end face of female nail bar section, machining has been wasted raw material on the one hand; On the other hand, this production technology takes a lot of work, time-consuming, increased again investment and the equipment cost of equipment.
Summary of the invention
The utility model purpose is that a kind of employing mould punching, the straight end face of the flat processing of bundle female nail bar section are provided in order to overcome the deficiencies in the prior art, and will contracting bar, cut the nut that straight end face two procedures is combined into a procedure and follow closely side cut, contracting bar one-time-shaped mould.
For achieving the above object, the technical solution adopted in the utility model is: a kind of nut nail is cut edge, contracting bar one-time-shaped mould, comprises upper die and lower die, and described patrix bottom is provided with solid die, described counterdie comprises lower formwork, gland and is successively set on the interior edger of lower formwork, jacking block; Described jacking block is connected to the bottom of edger; The bar section straight end face shape chamber that be provided with female nail head shape chamber in the described edger, communicates with female nail head shape chamber; Be provided with the ejection sleeve that is used in conjunction with mother's nail in the described jacking block; Also be provided with the guarantor hole thimble that passes ejection sleeve on the described jacking block; Described jacking block is connected on the lower formwork by gland; Connect a top rod on the described ejection sleeve.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The nut nail of the utility model scheme is cut edge, contracting bar one-time-shaped mould, adopts the straight end face of mould punching, the female nail of the flat processing of bundle bar section, makes it not produce any waste material, has saved raw material; To produce on the other hand the nut nail, just can finish with a punching machine mold and to cut straight end face and contracting bar and once finish, originally four procedures processing is reduced to three process can be finished, improve greatly labor productivity, saved manually electric power and the wearing and tearing that reduced equipment investment and equipment.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is a kind of nut pin structure schematic diagram of the present utility model;
Accompanying drawing 2 is a kind of nut nail face upwarding assumption diagram of the present utility model
Accompanying drawing 3 is that a kind of nut nail of the present utility model is cut edge, the structural representation of contracting bar one-time-shaped mould;
Wherein: 1, patrix; 2, counterdie; 3, lower formwork; 4, solid die; 5, edger; 6, jacking block; 7, gland; 8, female nail head shape chamber; 9, the straight end face shape of bar section chamber; 10, ejection sleeve; 11, protect the hole thimble; 12, top rod; 13, screw; 14, female nail.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As the described a kind of nut nail of accompanying drawing 1 cut edge, contracting bar one-time-shaped mould, comprise patrix 1, counterdie 2, described patrix 1 bottom is provided with solid die 4, described counterdie 2 comprises lower formwork 3, gland 7 and is successively set on the interior edger 5 of lower formwork 3, jacking block 6; Described jacking block 6 is connected to the bottom of edger 5, plays the effect of supporting edger; The bar section straight end face shape chamber 9 that be provided with female nail head shape chamber 8 in the described edger 5, communicates with female nail head shape chamber 8; Be provided with in the described jacking block 6 with mother and follow closely 14 ejection sleeve that are used in conjunction with 10; Also be provided with the guarantor hole thimble 11 that passes ejection sleeve 10 on the described jacking block 6; Described jacking block 6 is connected on the lower formwork 3 by screw 13 with gland 7; The afterbody of described ejection sleeve 10 connects a top rod 12.Add man-hour, mother is followed closely 14 put into the shape chamber, protect hole thimble 11 and insert in female nail 14 bottom centre holes, patrix 1 downward punching press, former cylindrical bar section restraints flat in straight end face shape chamber 9 by force, under the support of ejection sleeve 10 and jacking block 6, gland 7, finishes and cuts straight end face, contracting bar operation; After finishing, rear jacking rod 12 promotes ejection sleeve 10 the female nail 14 of its drive is deviate from from edger 5.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
