Abstract

The utility model discloses a three thimble structure of fundamental mode core activity, include: fundamental mode core and die, the die sets up in the top of fundamental mode core, a through -hole has been seted up to the bottom of fundamental mode core, be provided with the product thimble in the through -hole, the product thimble can remove in the through -hole, the outside of product thimble is provided with the round ejector sleeve, push away the external diameter that the bore of pipe is greater than the product thimble, the external diameter of ejector sleeve is greater than the maximum diameter of fundamental mode core bottom through -hole the below of fundamental mode core is provided with the spring, the quantity of spring is two at least the below of ejector sleeve is provided with at least three ejector sleeve thimble. In this way, the utility model discloses can solve have the product that the ring flange need punch again can't be with the problem of cold heading machine processing.

Description

Three thimble structures that main core rod is movable
Technical field
This utility model relates to cold upsetting die of car field, particularly relates to three thimble structures that a kind of main core rod is movable。
Background technology
Cold-heading is the forging method utilizing mould at normal temperatures metal bar material jumping-up (often for gathering stock) to be shaped。It is commonly used to manufacture the head of screw, bolt, rivet etc.。Can reduce or replace machining。
But, when run into have ring flange and also again need punching product time, simple three thimble structures can not meet production needs, if not changing ejecting mechanism, that product cannot punch, and product is necessary for the processing relying on follow-up lathe to complete hole, cause the waste of material, the increase of cost。
Utility model content
This utility model is mainly solving the technical problems that provide three thimble structures of a kind of main core rod activity, it is possible to solve to need again the product of punching cannot use the mach problem of cold-heading with ring flange。
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide three thimble structures that a kind of main core rod is movable, including: main core rod and punch die, described punch die is arranged at the top of main core rod, the bottom of described main core rod offers a through hole, it is provided with product thimble in described through hole, described product thimble can move in through hole, the outside of described product thimble is provided with a circle ejector sleeve, the internal diameter of described ejector sleeve is more than the external diameter of product thimble, the external diameter of described ejector sleeve is more than the maximum gauge of main core rod bottom through-hole, it is arranged below spring at described main core rod, the quantity at least two of described spring, it is arranged below at least three ejector sleeve thimble at described ejector sleeve。
Preferably, the quantity of described ejector sleeve thimble is three。
Preferably, punching rod it is provided with in described punch die。
The beneficial effects of the utility model are: this utility model after main core rod equipped with spring, after the bar of blank is completely into main core rod, punch die pushes main core rod to start blank is punched, solve and need again with ring flange the product of punching cannot use the mach problem of cold-heading, there is the advantages such as widely applicable, stock utilization is high, productivity ratio is higher, production cost is relatively low。
Accompanying drawing explanation
Fig. 1 is the structural representation of three thimble structure one preferred embodiments of the main core rod activity of this utility model;
In accompanying drawing, the labelling of each parts is as follows: 1, punch die, and 2, main core rod, 3, ejector sleeve, 4, spring, 5, product thimble, 6, ejector sleeve thimble, 7, blank, 8, punching rod。
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining。
Referring to Fig. 1, this utility model embodiment includes:
Three thimble structures that a kind of main core rod is movable, including: main core rod 2 and punch die 1, described punch die 1 is arranged at the top of main core rod 2, the bottom of described main core rod 2 offers a through hole, product thimble 5 it is provided with in described through hole, described product thimble 5 can move in through hole, the outside of described product thimble 5 is provided with a circle ejector sleeve 3, the internal diameter of described ejector sleeve 3 is more than the external diameter of product thimble 5, the external diameter of described ejector sleeve 3 is more than the maximum gauge of main core rod 2 bottom through-hole, it is arranged below spring 4 at described main core rod 2, the quantity of described spring 4 is two, it is arranged below at least three ejector sleeve thimble 6 at described ejector sleeve 3。
Main core rod 2 times is equipped with spring 4, and after the bar of blank 7 is completely into main core rod 2, punch die 1 pushes main core rod 2 to start blank 7 is punched, and main core rod 2 is resetted by rear spring of having punched 4, and product is ejected by ejector sleeve thimble 6。
As shown in Figure 1, after blank 7 thin rod portion is pushed completely into main core rod 2 by punch die 1, punching rod 8 continues to push blank 7 motion and starts punching, owing to main core rod 2 is presented herein below spring 4, so main core rod 2 can protect blank 7 and complete drill process, then punch die 1 resets, spring 4 pushes main core rod 2 and resets, ejecting mechanism pushes ejector sleeve thimble 6, and ejector sleeve thimble 6 pushes ejector sleeve 3, and ejector sleeve 3 is again by product ejection die。
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model。
