Abstract
The utility model discloses a floating mandrel forming buoyancy elastic ejection type blanking precision mould. The blanking precision mould comprises an upper mould seat (1), a fixing plate (2), a lower mould seat (8), a lower cushion plate (7), a concave template (6) and a middle template (4), and is characterized in that a floating block (9) is movably mounted in a position corresponding to the concave template (6) at the lower end of a blank punching head (3); the floating block (9) is movably mounted in a blanking concave mould (10) and is in threaded connection with a limiting screw (11); and a rectangular spring (12) with a strong force is mounted at the lower end of the limiting screw (11). The blanking precision mould is simple in structure and produced workpieces are high in planeness quality.
Description
Technical field
The utility model belongs to mould, particularly a kind of buoyancy bullet top formula blanking precision die that uses on the printer of producing.
Background technology
At present, because the workpiece profile that printer needs is larger and it is tight that flatness is required, adopt common Production of Stamping Die workpiece out, can't guarantee the flatness requirement of workpiece, processing difficulties, difficult quality guarantee.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of to increase powerful bullet top in the part die that falls, strip compresses the buoyancy bullet top formula blanking precision die that the planeness of workpiece quality is high by bullet top and blanking die all the time in the stamping-out process.
The technical scheme that the utility model technical solution problem adopts is: a kind of buoyancy bullet top formula blanking precision die, comprise upper bolster, fixed head, die shoe, lower bolster, concave template and middle template, it is characterized in that on fall part drift lower end and concave template opposite position, filling actively a rocker piece, rocker piece is contained in the blanking die actively, and be threaded with stop screw, the stop screw lower end fills the Rectangular Spring of a brute force.
The beneficial effects of the utility model are that this utility model is simple in structure, the planeness of workpiece quality height of production.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing
Fig. 1 is the front view of Shift spindle moulding buoyancy bullet top formula blanking precision die;
Fig. 2 is the A-A cutaway view of figure.
Among the figure: the 1-upper bolster; The 2-fixed head; The 3-part drift that falls; Template among the 4-; The 5-strip; The 6-concave template; 7-counterdie backing plate; The 8-die shoe; The 9-rocker piece; The 10-blanking die; The 11-stop screw; The 12-Rectangular Spring; The 13-plug screw; The 14-cover.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of buoyancy bullet top formula blanking precision die, comprise upper bolster 1, fixed head 2, die shoe 8, lower bolster 7, concave template 6 and middle template 4, it is characterized in that movablely on fall part drift 3 lower ends and concave template 6 opposite positions must filling a rocker piece 9, rocker piece 9 is contained in the blanking die 10 actively, and is threaded with stop screw 11, and stop screw 11 lower ends fill the Rectangular Spring 12 of a brute force.Fix a fixed head 2 below the upper bolster 1, fill the part drift 3 that falls in the middle of the fixed head 2, the middle template 4 of passing of part drift 3 activities that falls contacts with strip 5, being contained between middle template 4 and the concave template 6 of strip 5 activities, be connected with counterdie backing plate 7 below the concave template 6, cover 14 is housed on the counterdie backing plate 7 and links together with die shoe 8, plug screw 13 is equipped with in the lower ends, hole in the middle of the die shoe 8.
During production and processing, first buoyancy bullet top formula blanking precision die is installed on the working platform of punching machine, installs strip 5 and get final product downward punching press upper bolster 1, cause workpiece all the time by rocker piece 9(bullet top) compress with the part drift 3 that falls, guarantee that the work piece platform flatness is smooth.
