Abstract
The utility model relates to a one-step forming die for a steel cap of a pin insulator. The die comprises an upper die plate and a lower die plate, and is characterized in that the upper die plate is equipped with a punch, the lower die plate is provided with a die holder, a left die and a right die are symmetrically arranged in the die holder, T-shaped slide block structures are arranged on the outer sides of both the left die and the right die, T-shaped guide grooves capable of being in embedded connection with the T-shaped slide blocks are formed on the die holder and obliquely and upwardly extend from the outside of the bottom of the die holder, the inner side surfaces of both the left die and the right die are respectively connected with a left die core and a right die core through bolts, and the left die core and the right die core are combined to form a cavity for the steel cap of the pin insulator. The punch and the left and the right die cores work together to achieve one-step punch forming of the steel cap of the pin insulator, the punch forming effect is good and the yield is high. During demoulding, a demoulding cylinder below jacks up the left die and the right die to enable the left and the right dies to open toward two sides under the action of the T-shaped slide blocks and the T-shaped guide grooves, so as to realize demoulding of the steel cap.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of pin insulator steel cap one-time-shaped mould.
Background technology
Pin insulator steel cap is used for rural power grids, net 20KV following tower bar in city connects with lead, and as shown in Figure 1, it is made up of cast pressure contact portion 10 and seat part 11.The mode of producing this kind pin insulator steel cap at present has two kinds: a kind of is the method moulding of adopting casting, and it exists shortcoming to be: interior tissue is loose, and defectives such as shrinkage cavity, crackle are arranged, and can't meet the quality requirement, and has bigger potential safety hazard, and scraps more.
Can also adopt the method for forging, it adopts dies cavity is the die cavity of pin insulator steel cap, be to realize discharging, and the pressure contact portion of steel cap is down, seat part up, through the drift punch forming.This kind shortcoming is: the steel cap pressure contact portion that forges very easily occurs causing scrapping of product towards the not enough phenomenon of shape, and power consumption is high, and yield rate is low, and cast pressure contact portion hole can not forge, and must just can make through machined, and manufacturing cost is very high.
Summary of the invention
The technical problem that the utility model will solve provides the pin insulator steel cap one-time-shaped mould that a kind of efficient is high, yield rate is high.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of pin insulator steel cap one-time-shaped mould comprises cope match-plate pattern, lower bolster; Its innovative point is: on the said cope match-plate pattern drift is installed; Lower bolster is provided with die holder, is arranged with left mould and right mould in the die holder, and said left mould and right mould arranged outside have T shape slide block structure; Die holder be provided with can chimeric T shape slide block T shape guide groove, extend this T shape guide groove oblique top outside the bottom of die holder; The medial surface of said left mould and right mould is connected with left die and right die through bolt respectively, and left die and right die constitute the die cavity of a pin insulator steel cap.
The advantage of the utility model is: fit into the one time punching molded of indicator type insulator steel cap through drift and left and right die, effective towards shape, yield rate is high.During the demoulding,, make left and right mould under the effect of T shape slide block and T shape guide groove, open, realize the demoulding of steel cap to both sides by the left and right mould of stripping tank jack-up of below.
Description of drawings
Fig. 1 is a pin insulator steel cap sketch map.
Fig. 2 is the utility model pin insulator steel cap one-time-shaped mould structural representation.
Fig. 3 is the vertical view of the utility model die holder and left mould, right mould.
The specific embodiment
Like Fig. 2, shown in 3, comprise cope match-plate pattern 1, drift 2, lower bolster 3, die holder 4, left mould 5, right mould 6, pilot hole 9, left die 7 and right die 8.
Through fixed head drift 2 is installed on the above-mentioned cope match-plate pattern 1; Lower bolster 3 is provided with die holder 4; Be arranged with left mould 5 and right mould 6 in the die holder 4; This left side mould 5 has T shape slide block structure with right mould 6 arranged outside, die holder 4 be provided with can chimeric T shape slide block T shape guide groove, this T shape guide groove is the extension of oblique top from the bottom of die holder outside.
Four jiaos of cope match-plate pattern 1 are equipped with lead, and four jiaos of die holder 4 are provided with the pilot hole corresponding with lead 9.
The medial surface of left side mould 5 and right mould 6 is connected with left die 7 and right die 8 through bolt respectively, and left die 7 and right die 8 constitute the die cavity of a pin insulator steel cap, and the top of this die cavity is cast pressure contact portion cylindrical die cavity, following position seat part profile die cavity.
During use, fit into the punch forming of indicator type insulator steel cap by drift and left and right die.
