Abstract

The utility model relates to the technical field of machines, and in particular relates to a restriction orifice lower punch comprising a lower punch body. The restriction orifice lower punch is characterized in that the bottom of the lower punch body is connected with a two-stage step, wherein an upper-end step of the two-stage step has a diameter of 198 millimeters and a height of 60 millimeters; a lower-end step of the two-stage step has a diameter of 158 millimeters and a height of 65 millimeters; the bottom of the lower-end step of the two-stage step is connected with a threaded rod; the top of a lower punch body is connected with a punch. Compared with the prior art, the restriction orifice lower punch disclosed by the utility model is designed with the lower punch special for an orifice work-piece mold so as to ensure that the lower punch is matched with the orifice work-piece mold in the process that orifice work-pieces are processed by the lower punch, thus the processing efficiency and product quality of the orifice work-pieces can be improved; the restriction orifice lower punch has the characteristics of novel, simple and practical structure and convenient and fast use.

Description

A kind of restricting orifice low punch
Technical field
The utility model relates to field of mechanical technique, definite says a kind of restricting orifice low punch.
Background technology
At present, large-scale throttle orifice workpiece, in process, generally adopts die cast, then is manufactured needed shape by manufacturing process such as grindings, such manufacture, not only production efficiency is low, and the end properties producing differs greatly, therefore, in order to improve production efficiency and the product quality of large-scale throttle orifice workpiece, design specialized is in the die sleeve of throttle orifice workpiece, and in order to coordinate the use of die sleeve, need to design a kind of drift of processing throttle orifice workpiece.
Summary of the invention
The utility model, for overcoming the deficiencies in the prior art, designs a kind of low punch that can match with throttle orifice part mould.
For achieving the above object, design a kind of restricting orifice low punch, comprise low punch body, it is characterized in that: the bottom of described low punch body connects two stage steps, and the upper end step diameter of described two stage steps is 198 millimeters, is highly 60 millimeters, the lower end stepped diameters of two stage steps is 158 millimeters, be highly 65 millimeters, the bottom connecting thread bar of the lower end step of two stage steps, the top of described low punch body connects drift.
The cross section of described drift is circular, and the vertical cross-section of drift is short trapezoidal in long top, bottom.
The cross section of described low punch body is circular, and the vertical cross-section of low punch body is short trapezoidal in long top, bottom, is the inclination angle of 3.5 ° between the lateral surface of low punch body and vertical direction.
The lower surface of described drift is identical with the diameter of the upper surface of low punch body.
The middle part of the lower end step of described two stage steps is provided with through hole.
Described through hole level runs through the lower end step of two stage steps.
The utility model compared with the existing technology, designed the low punch that is exclusively used in throttle orifice part mould, make low punch in to the process of throttle orifice workpiece processing, match with throttle orifice part mould, thereby improved working (machining) efficiency and the product quality of throttle orifice workpiece; There is novel structure, simple, practical, convenient to use feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1, wherein, the 1st, drift, the 2nd, low punch body, the 3rd, two stage steps, the 4th, through hole, the 5th, threaded rod.
The specific embodiment
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1, bottom at low punch body 2 connects two stage steps 3, the upper end step diameter of two stage steps 3 is 198 millimeters, be highly 60 millimeters, the lower end stepped diameters of two stage steps 3 is 158 millimeters, is highly 65 millimeters, the bottom connecting thread bar 5 of the lower end step of two stage steps 3, the top of low punch body 2 connects drift 1, and wherein the cross section of drift 1 be circular, and the vertical cross-section of drift 1 is bottom and grows short trapezoidal in top.
The cross section of low punch body 2 is circular, and the vertical cross-section of low punch body 2 is short trapezoidal in long top, bottom, is the inclination angle of 3.5 ° between the lateral surface of low punch body 2 and vertical direction.The lower surface of drift 1 is identical with the diameter of the upper surface of low punch body 2.
The middle part of the lower end step of two stage steps 3 is provided with through hole 4, and through hole 4 levels run through the lower end step of two stage steps 3.
When the utility model is used, processing equipment and threaded rod 5 are interfixed, to put into throttle orifice part mould for rapidoprint, and rotate by the low punch body 2 that rotarily drives of threaded rod 5, make drift 1 rotation, and support the use with throttle orifice part mould, thereby obtain the effect of extrusion process, promoted the quality of working (machining) efficiency and product.
