Abstract
The utility model relates to a fine blanking die for a square hole of a moving iron core for an automobile starter switch. The traditional milling method adopted for processing the square hole in a square bar has the disadvantages that the processing efficiency is low, and the production cost is high. The fine blanking die for the square hole of the moving iron core for the automobile starter switch is characterized in that the fine blanking die comprises an upper die seat, an upper die backing plate, a punch needle fixing plate, a big punch needle, stripping plates, a small punch needle, an anti-warping baffle plate, a baffle plate, a baffle plate seat, a material frame, a female die, a lower die seat, guide columns and guide sleeves; the upper die backing plate and the punch needle fixing plate are fixed on the upper die seat; the two guide columns are arranged on the upper die seat; the stripping plates are sleeved on the two guide columns on the upper die seat; both the big punch needle and the small punch needle are spliced in the punch needle fixing plate; the anti-warping baffle plate is fixed on the punch needle fixing plate; the baffle plate seat, the material frame and the female die are fixed on the lower die seat; the baffle plate is movably connected with the baffle plate seat; the guide columns and the guide sleeves are respectively fixed on the lower die seat and the upper die seat; and both the big punch needle and the small punch needle are matched with the female die. The fine blanking die has the advantages of reasonable structural design, high processing efficiency and low production cost.
Description
Technical field
The utility model relates to a kind of mould, especially relates to the moving iron core square hole fine-edge blanking mould of a kind of automobile starter switch, is exclusively used in the moving iron core square hole of processing automobile starter motor switch.
Background technology
The moving iron core of automobile starter switch is the structure of cylinder band square bar, is provided with a square hole at the square bar place, and the common method for milling of common at present employing is processed the square hole in the square bar, and working (machining) efficiency is low, the production cost height.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and is easy to use, working (machining) efficiency height, the moving iron core square hole fine-edge blanking mould of the automobile starter switch that production cost is low.
The technical scheme in the invention for solving the above technical problem is: the characteristics of the moving iron core square hole fine-edge blanking mould of this automobile starter switch are: comprise upper bolster, upper die plate, towards the pin fixed head, the favourable opposition pin, stripper plate, little of pin, the anti-baffle plate that sticks up, baffle plate, apron block, material supporting rack, die, die shoe, guide pillar and the guide pin bushing that is complementary with guide pillar, described upper die plate and all be fixed on the upper bolster towards the pin fixed head, this upper die plate is towards between pin fixed head and the upper bolster, described upper bolster is provided with two leads, described stripper plate is sleeved on two leads of upper bolster, described favourable opposition pin and all be plugged in the pin fixed head towards pin for a short time describedly anti-ly sticks up baffle plate and is fixed on the pin fixed head; Described apron block, material supporting rack and die all are fixed on the die shoe, and described baffle plate is movably connected on the apron block; Described guide pillars and bushes is separately fixed on die shoe and the upper bolster, and this guide column sleeve is contained in the guide pin bushing, described favourable opposition pin and all be complementary with die towards pin for a short time.
Stripper plate described in the utility model and between the pin fixed head, be provided with elastic caoutchouc.
Upper die plate described in the utility model and be fixed on the upper bolster by screw towards the pin fixed head.
The utility model compared with prior art has the following advantages and effect: 1, baffle plate can be movable on apron block, adopts the structure of sideboard, can effectively control die-cut datum level, guarantees the positional precision of square hole.2, square hole and square bar length one-step punching are shaped, and guarantee relative position and dimensional accuracy height, the working (machining) efficiency height.3, adopt elastic blank holding punching structure, die-cut cross section quality height.4, mould adopts structures such as guide pillar guide pin bushing, guiding accuracy height.5, square hole adopts insert structure towards pin, changes soon, saves die cost.
Of the present utility model simple in structure, reasonable in design, easy to use, can effectively increase work efficiency, reduce production costs.
