Abstract
The utility model provides a convex die fixing part, comprising a convex die fixed plate and a fixed component; the convex die fixed plate is provided with a convex die installation hole; wherein, the convex die fixed plate is provided with the installation structure of the fixed component which is communicated with the convex die installation hole; the fixed component tightly locks the convex die on the convex die fixed plate by the installation structure. The installation structure of the fixed component is arranged at one side of the convex die installation hole of the convex die fixed plate. The installation structure of the fixed component comprises a convex part with a through hole and slots which are arranged at two sides of the convex part; the slots close to one side of the convex die installation hole are communicated with the convex die installation hole. The convex die fixing part has simple structure and is easy to be processed; more importantly, the convex die fixing part avoids the disadvantageous situation that the strength of the convex die is reduced as a notch is arranged on the convex die; furthermore, as the front end surface of a fixed bolt and the convex die installation hole are closely matched with the side surface of the convex die, the match precision is increased, the strength of the fixed convex die is reinforced, and the application reliability is effectively ensured.
Description
[technical field]
The utility model relates to a kind of fixture of punch.
[background technology]
At present, in the mould of punching press class at home and abroad, punch adopts the fixed form of hanging platform usually.But some punch is complex-shaped, can't adopt Digit Control Machine Tool processing and employing line cutting processing.As everyone knows, the line cutting processing can't process step.For this class punch, can only adopt bolt that punch is fixed on the punch retainer.And if punch is small-sized, can't use bolting.This is the fixedly difficult problem of aspect of small-sized punch.For this difficult problem, the someone proposed such solution: the non-forming ends at punch mills out notch, uses the fixedly inserted sheet that cooperates with notch that punch is fixed in the ladder hole on the punch retainer.
This method has solved the fixedly difficult problem of aspect of small-sized punch to a certain extent.But diel mills out notch and will reduce its intensity the requirement of strength height of punch on small-sized punch, influenced the dependability and the life-span of punch.
[utility model content]
The purpose of this utility model is to overcome deficiency and the shortcoming of the middle-size and small-size punch of prior art aspect fixing, provides a kind of punch strength that guarantees, the punch retainer that dependability is high.
The utility model is by the following technical solutions: a kind of punch retainer, comprise punch retainer, fixation kit, described punch retainer is provided with the punch installing hole, it is characterized in that: described punch retainer is provided with the mounting structure of the fixation kit that is connected with the punch installing hole, and described fixation kit is locked at punch on the punch retainer by its mounting structure.
As further improvement in the technical proposal, the mounting structure of described fixation kit is arranged at a side of the punch installing hole of punch retainer.
As further improvement in the technical proposal, the mounting structure of described fixation kit comprises that one has the protuberance of through hole, and the short slot that is arranged at the protuberance both sides, and the short slot that approaches punch installing hole one side is connected with the punch installing hole.
As further improvement in the technical proposal, described through hole is unthreaded hole or screwed hole;
As further improvement in the technical proposal, described fixation kit comprise bolt and with the bolt thread nut engaged.
As further improvement in the technical proposal, the cross sectional shape of described punch installing hole matches with the cross sectional shape of punch.
As further improvement in the technical proposal, described bolt has and the suitable recess of punch side view.
As further improvement in the technical proposal, the center line of the center line of described through hole and punch installing hole is in same plane.
As further improvement in the technical proposal, leave an amount of installation surplus between the bolt head of described bolt and the protuberance of punch retainer.
Design of the present utility model is not only simple in structure, is easy to processing; The more important thing is and avoided on punch, opening the decline of notch being installed and causing punch strength, the rough sledding that reduce service life; And because closely cooperating of set bolt front end face and punch installing hole and punch side not only increased quality of fit, also strengthened the intensity of solid punch, effectively guaranteed the reliability of using.

[specific embodiment]
Following by specific embodiment and in conjunction with the accompanying drawings the utility model be described in further detail.Extremely shown in Figure 2 as Fig. 1, a kind of punch retainer, comprise punch retainer 1, fixation kit, described punch retainer 1 is provided with punch installing hole 3, wherein, described punch retainer 1 is provided with the mounting structure of the fixation kit that is connected with punch installing hole 3, and described fixation kit is locked at punch 2 on the punch retainer 1 by its mounting structure.The mounting structure of described fixation kit is arranged at a side of the punch installing hole 3 of punch retainer 1.The mounting structure of described fixation kit comprises that one has the protuberance 6 of through hole 4, and the short slot 5 and 7 that is arranged at protuberance 6 both sides, and the short slot 7 that approaches punch installing hole 3 one sides is connected with punch installing hole 3.The cross sectional shape of described punch installing hole 3 matches with the cross sectional shape of punch 2, finishes with the line cutting processing.And the center line of the center line of described through hole 4 and punch installing hole 3 is in same plane.
As one of them embodiment, described through hole 4 can be screwed hole, and described fixation kit is the nut 9 of bolt 8 and bolt 8 threaded engagement.During installation, bolt 8 cooperates with screwed hole 4, and swivel bolt 8 makes it move until with enough intensity punch 2 being fixed and fastening nuts 9 to punch 2 directions.
As embodiment more preferably, to shown in Figure 4, described through hole 4 can be unthreaded hole as Fig. 3; Described fixation kit comprise bolt 8 and with the nut 9 of bolt 8 threaded engagement, described bolt 8 has and the suitable recess of punch 2 side views, described recess can coat the part side of punch 2.In the installation process, punch 2 is cooperated with punch installing hole 3 on the punch retainer 1 to install earlier; Again bolt 8 is passed through hole 4 and make its front end face and work good in punch 2 sides with recess; Only rotate nut 9 and make bolt 8,, can improve the intensity of bolting punch more until punch 2 is fixing with enough intensity not rotatably to punch 2 direction translations.
In addition, for guaranteeing that bolt 4 has the enough amount of feeding, under installment state, leave an amount of installation surplus between the bolt head of bolt 4 and the protuberance of punch retainer 6.
The specific embodiment of the above is a better embodiment of the present utility model, is not to limit concrete practical range of the present utility model with this, and the equivalence that all shapes according to the utility model, structure are done changes all in protection domain of the present utility model.
