Abstract
The utility model discloses a die used for manufacturing a thick-wall hemispherical end socket, and a punch and the hemispherical end socket are separated rapidly. The die comprises a lower die frame and an upper die frame located above the lower die frame, wherein the upper die frame is provided with the punch corresponding to the inner surface of the hemispherical end socket, the lower die frame is provided with a lower die with an annular section, the inner wall of the lower die is provided with an annular step, a pull ring is placed on the upper surface of the step, the inner diameter of the pull ring is equal to that of the step, at least two blanking bars which are evenly and roundly distributed are transversely arranged in the lower die in a sliding mode, and one end of each blanking bar is located in the step and can penetrates out of the inner surfaced of the step. The die has the advantages that due to the fact that the hemispherical end socket is blocked after the blanking bars stretch out of the step, the punch can be rapidly separated from the hemispherical end socket when rising again, and therefore production efficiency is increased.
Description
Technical field
The utility model relates to a kind of mould for the manufacture of spherical thick head.
Background technology
The mould of conventional manufacture spherical thick head comprises lower mold holder and is positioned at the top mold frame of lower mold holder top, is provided with the drift corresponding with the inner surface of segment seal head in top mold frame, is provided with little mould on die shoe.Particularity and wall thickness due to segment seal head material, wall thickness is at 135～196mm, before punching press, on blank, can be coated with one deck graphite, make after punching press completes, drift is easily extracted from segment seal head, but or can produce drift is embedded in situation about not departing from segment seal head, so just need workman that segment seal head is struck from drift, waste time and energy.
Utility model content
Technical problem to be solved in the utility model is: the mould for the manufacture of spherical thick head that provides a kind of drift and segment seal head to depart from fast.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of mould for the manufacture of spherical thick head, comprise lower mold holder and the top mold frame that is positioned at lower mold holder top, in top mold frame, be provided with the drift corresponding with the inner surface of segment seal head, on described lower mold holder, being provided with cross section is annular counterdie, on the inwall of counterdie, be provided with ring-shaped step, the upper surface rests of step is equipped with draw ring, the internal diameter of draw ring and the internal diameter of step equate, in counterdie, laterally slide and be provided with at least two rounded uniform blanking rods, one end of blanking rod is arranged in step and can passes from the inner surface of step.
Rounding between the upper surface of described draw ring and inwall, and radius of corner R=2.5 δ, the wall thickness that δ is segment seal head, δ is 135～196mm.
Under described drift, be provided with the oil cylinder that the good segment seal head of punching press is upwards pushed up.
The upper surface of described lower mold holder is provided with several alignment pins that blank is positioned.
The beneficial effects of the utility model are: after utilizing blanking rod to stretch out from step, by segment seal head bumping post, drift departs from fast with regard to energy and segment seal head when ging up, thereby enhances productivity.

The specific embodiment
Describe specific embodiments of the present utility model below in detail.
As shown in Figure 1, mould for the manufacture of spherical thick head described in the utility model, comprise lower mold holder 1 and the top mold frame 2 that is positioned at lower mold holder 1 top, in top mold frame 2, be provided with the drift corresponding with the inner surface of segment seal head 3, on described lower mold holder 1, being provided with cross section is annular counterdie 4, on the inwall of counterdie 4, be provided with ring-shaped step 5, the upper surface rests of step 5 is equipped with draw ring 6 (being convenient to the replacing of draw ring), the internal diameter of the internal diameter of draw ring 6 and step 5 equates, in counterdie 4, laterally slide and be provided with at least two rounded uniform blanking rods 7 (general uniform three blanking rods when actual production), one end of blanking rod 7 is arranged in step and can passes from the inner surface of step 5.For fear of segment seal head, in punching press, pull, and be more easily shaped, surface quality is good, qualification rate is high, rounding between the upper surface of described draw ring 6 and inwall, and radius of corner R=2.5 δ, the wall thickness that δ is segment seal head, δ is 135～196mm.For the ease of taking out segment seal head, under described drift 3, be provided with the oil cylinder 8 that the good segment seal head of punching press is upwards pushed up.In order to prevent blank off normal when placing, the upper surface of described lower mold holder 1 is provided with several alignment pins that blank 9 is positioned 10.
The course of work of the present utility model is: as shown in Figure 1, first blank 9 is placed on counterdie 4, by alignment pin 10, located, then drift 3 presses down, blank 9 is stamping, due to the fillet in draw ring 6 is reasonable in design, the lower surface that makes blank 9 can not pulled in the process of distortion, and be more easily shaped, surface quality is good.After segment seal head is shaped, blanking rod 7 is stretched out and is against the upper edge of segment seal head from the inwall of step 5, in the process that makes rising at drift 3, segment seal head has been hindered and cannot rise by blanking rod 7, thereby reaches drift 3 and the quick separated object of segment seal head.Finally regain blanking rod 7, utilize oil cylinder 8 that segment seal head is ejected from lower mold holder 1.Aforesaid operations process is simple, quick, greatly improved production efficiency, and the qualification rate of product is very high, and because segment seal head is all large-scale, and wall thickness is larger, and therefore high qualification rate can reduce the production cost of enterprise, thereby improves productivity effect.
Claims (4)
