Abstract

The utility model relates to a one-time forming die for a pin-type insulator steel cap, comprising an upper die plate and a lower die plate, and its innovative point is that: a punch is installed on the upper die plate, a die base is provided on the lower die plate, a left die and a right die are symmetrically provided in the die base, a T-shaped slider structure is provided on the outer side of the left die and the right die, a T-shaped guide groove which can be fitted with the T-shaped slider is provided on the die base, and the T-shaped guide groove extends obliquely upward from the bottom of the die base; the inner side surfaces of the left die and the right die are respectively connected with a left die core and a right die core by bolts, and the left die core and the right die core are combined to form a mold cavity of a pin-type insulator steel cap. The pin-type insulator steel cap is punched and formed once by the cooperation of the punch and the left and right die cores, and the punching effect is good and the yield rate is high. When demolding, the left and right dies are lifted up by the demolding cylinder below, so that the left and right dies are opened to both sides under the action of the T-shaped slider and the T-shaped guide groove, so as to realize the demolding of the steel cap.

Description

One-time forming mold for steel cap of pin type insulator

technical field

The utility model relates to a mold, in particular to a one-time forming mold for a pin-type insulator steel cap. the

Background technique

Pin type insulator steel caps are used for the connection between tower rods and wires below 20KV in rural power grids and urban power grids. At present, there are two ways to produce this kind of pin insulator steel cap: one is to adopt the method of casting to form, and its disadvantages are: the internal structure is loose, there are defects such as shrinkage cavities and cracks, the quality cannot meet the requirements, and there are large potential safety hazards, and more scrapped. the

The method of forging can also be adopted, and the inner cavity of the mold is the cavity of the pin-type insulator steel cap. In order to realize unloading, the crimping part of the steel cap is on the bottom, and the support part is on the top, and it is formed by punching. The disadvantages of this kind are: the crimping part of the forged steel cap is prone to insufficient punching, resulting in product scrapping, high energy consumption, low yield, and the hole of the tube-shaped crimping part cannot be forged, so it must be machined Only then can it be made, and the manufacturing cost is very high. the

Contents of the invention

The technical problem to be solved by the utility model is to provide a pin-type insulator steel cap one-time molding die with high efficiency and high yield. the

In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a one-time forming mold for steel caps of pin type insulators, including an upper template and a lower template. A mold base is provided, and a left mold and a right mold are arranged symmetrically inside the mold base, and a T-shaped slider structure is arranged on the outside of the left mold and the right mold, and a T-shaped guide groove that can be fitted with a T-shaped slider is provided on the mold base , the T-shaped guide groove extends obliquely upward from the bottom of the mold base; the inner surfaces of the left mold and the right mold are respectively connected with a left mold core and a right mold core by bolts, and the combination of the left mold core and the right mold core forms a pin type The cavity of the steel cap of the insulator. the

The utility model has the advantages that: through the cooperation of the punch and the left and right die cores, the steel cap of the pin type insulator is punched and formed at one time, the punching effect is good, and the yield is high. When demolding, the left and right molds are lifted by the demoulding cylinder below, so that the left and right molds are opened to both sides under the action of the T-shaped slider and the T-shaped guide groove, and the demoulding of the steel cap is realized. the

Detailed ways

As shown in Figures 2 and 3, it includes an upper template 1, a punch 2, a lower template 3, a mold base 4, a left mold 5, a right mold 6, a guide hole 9, a left mold core 7 and a right mold core 8. the

On the above-mentioned upper template 1, a punch 2 is installed through a fixed plate, and a mold base 4 is provided on the lower template 3, and a left mold 5 and a right mold 6 are symmetrically arranged in the mold base 4, and the left mold 5 and the right mold 6 are provided with a T-shaped slider structure, the mold base 4 is provided with a T-shaped guide groove that can be fitted with a T-shaped slider, and the T-shaped guide groove extends obliquely upward from the bottom of the mold base. the

The four corners of the upper formwork 1 are provided with guide posts, and the four corners of the mold base 4 are provided with guide holes 9 corresponding to the guide posts. the

The inner surfaces of the left mold 5 and the right mold 6 are respectively connected with a left mold core 7 and a right mold core 8 by bolts, and the left mold core 7 and the right mold core 8 are combined to form a cavity of a pin-type insulator steel cap. The upper part is the outer circular cavity of the tubular crimping part, and the lower part is the external cavity of the support part. the

When in use, the pin type insulator steel cap is stamped and formed by the cooperation of the punch and the left and right mold cores. the
