Abstract
The invention provides a crane oil shield blanking die structure. Through the invention, a large flaky waste material produced in the punch forming process of the parts of the crane oil shield can be primarily cut so that the flaky waste material falling into a waste material pool is small, the space is saved and possible cut of operators picking the material is avoided. The structure comprises two female dies and two male dies; the female dies are connected with the male dies through a connecting rod and a guide sleeve; and the structure is characterized in that: a cutter is arranged in a middle area between the two female dies, and the vertical height of the cutter is lower than that of the two female dies.
Description
Technical field
The present invention relates to make lifting machine oil cover part forming mould structure, be specially a kind of lifting machine oil cover blanking die structure.
Background technology
Oil cover part generally all adopts a kind of thin plate material as crane vehicle body vitals partly, goes out circular thin-wall part through punch process, carries out follow-up stretch process then; Consider the utilization rate of thin plate, during punching press, dash arranging of material and want rationally as far as possible; Circular piece normally with whole material in two, carries out punching press respectively; Like this, the every matched moulds of upper die and lower die once, the middle waste material that just cuts out similar I shape.If let this waste material directly fall into waste tank, not only take up room, manual remove waste material waste man-hour, and waste material is laminar easy incised wound operative employee.
Summary of the invention
There is above-mentioned defective to prior art; The invention provides a kind of lifting machine oil cover blanking die structure; Can the big sheet waste material that produce in the lifting machine oil cover part punching forming process tentatively be cut; Make that the sheet waste material profile fall into behind the waste tank is little, save the space, avoid manual work to pick up the phenomenon that material might cause the incised wound operative employee.
Its technical scheme is such:
It comprises die, punch; Said die and punch respectively have two; Said die is connected through guide rod, guide pin bushing with said punch, it is characterized in that: at said two die zone lines cutting knife is set, the vertical height of said cutting knife is lower than the vertical height of said two dies.
It is further characterized in that: said cutting knife is arranged along the linear position between two dies; Said die is installed on the die pedestal, and said punch is installed the punch pedestal; Said cutting knife is positioned at said two die zone lines, is installed on the said die pedestal.
The present invention adopts after the said structure; When the waste material blanking that produces in the lifting machine oil cover part punching forming process, waste material is fallen on the cutting knife that is positioned at two die zone lines, because the own wt effect is cut in half by cutting knife; Reduced the appearance and size of waste material; Thereby after waste material falls into waste tank, can save the space, avoid manual work to pick up the phenomenon that material might cause the incised wound operative employee.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is an A-A cutaway view of the present invention.
The specific embodiment
See Fig. 1, Fig. 2, die of the present invention 1, punch 2, die 1 respectively has two with punch 2; Die 1 is connected through guide rod 3, guide pin bushing 4 with punch 2; At two dies, 1 zone line 5 cutting knife 6 is set, the vertical height of cutting knife 6 is lower than the vertical height of die 1, and cutting knife 6 is arranged along the linear position between two dies 1; Die 1 is installed on die pedestal 7, and punch 2 is installed punch pedestal 8; Cutting knife 6 is positioned at two dies, 1 zone line 5, is installed on the die pedestal 7, and 9 is workpiece among the figure.
Below in conjunction with Fig. 1, Fig. 2 the course of work of the present invention is described:
When to the moulding of lifting machine oil cover part punching, workpiece 9 places on the die 1, and punch 2 is along guide rod 3 descending and die 1 matched moulds; Workpiece 9 moulding that is stamped, it is up that forming process finishes punch 2, sticks to workpiece waste material on the punch 2 simultaneously with blanking in the up process of punch 2; Waste material falls into two dies, 1 zone line 5; Because be cut off into two after own wt effect waste material is fallen on the cutting knife 6, the appearance and size of waste material reduces, such waste material places waste tank than saving the space in the past.
