Abstract
The utility model relates to the field of machines, in particular to a punching die sleeve for a long nut. The punching die sleeve comprises threaded holes, a vertical hole, a die sleeve body and horizontal column bodies; the middle of each of left and right sides of the die sleeve body is provided with one horizontal column body; each of left and right sides of the bottom of the die sleeve is provided with one threaded hole; and the vertical hole is formed in the middle of the die sleeve body. Compared with the prior art, the punching die sleeve has the advantages that the punching die sleeve special for the long nut is adopted, so that a die forging process for the long die sleeve is realized; and therefore, the mechanical property and yield of the long nut are improved, and production efficiency of metal machining is improved.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of perforation die sleeve of long nut.
Background technology
At present, long nut is in the flat-die forging operation stage.The long nut flat-die forging causes the waste of material more serious.But existing long nut can't be accomplished perforation because of the restriction of length in manufacturing process, and the loaded down with trivial details product that causes of long nut processing technology produces very big fringe cost.Therefore, design is a kind of can realize that the perforation Membrane cover of long nut die forging is vital.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of perforation Membrane cover that can realize the long nut die forging is provided.
In order to achieve the above object; The utility model comprises screwed hole, vertical hole, Membrane cover body and horizontal cylinder; It is characterized in that: the middle part of two sides respectively is provided with a horizontal cylinder about the Membrane cover body; Membrane cover body bottom each side be provided with a screwed hole, the middle part of Membrane cover body is provided with vertical hole.
The utility model is compared with prior art, adopts the perforation die sleeve structure that is exclusively used in long nut, makes the contour forging technique of long nut accomplished, thereby in mechanical performance that has improved long nut and qualification rate, has also improved the production efficiency of metalworking.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Referring to Fig. 1,1 is horizontal cylinder; 2 is the Membrane cover body; 3 is vertical hole; 4 is screwed hole.
The specific embodiment
Combine accompanying drawing that the utility model is done further describes at present.
Referring to Fig. 1, the utility model comprises screwed hole, vertical hole, Membrane cover body and horizontal cylinder.The middle part of about 2 two sides of Membrane cover body respectively is provided with a horizontal cylinder 1, Membrane cover body 2 bottoms each side be provided with a screwed hole 4, the middle part of Membrane cover body 2 is provided with vertical hole 3.
The utility model is when work, and material pushes and the punching step after implanting Membrane cover body 2 through the heating back simultaneously.In the time of semi-finished product profile basic forming after the completion, also accomplished the perforation of endoporus.So far, the utility model end-of-job.
