Description

It is a kind of that there is the squeeze riveter upper mold for keeping away bit function

Technical field

The utility model belongs in squeeze riveter component technology field, more particularly to it is a kind of have keep away on the squeeze riveter of bit function Mould.

Background technology

Squeeze riveter is a kind of new riveting equipment developed according to cold rolling principle, just refers to use rivet article riveting It picks up and carrys out mechanized equipment.The rivet having in the process that presses is close from convex closure or bending edges, can be damaged if pressing by force Original feature (convex closure hole, bending edges) etc., causes the damage of workpiece or scraps.

Utility model content

The purpose of this utility model is to solve problem above, and the utility model provides a kind of keep away on the squeeze riveter of bit function Mould.The technical solution of the utility model is achieved by the following way.

A kind of squeeze riveter upper mold for keeping away bit function, the head of squeeze riveter upper mold are that will be formed after a regular hexagon excision part It is polygonal, cut off formation side be notch；A part is that can realize the part for keeping away position；Position is kept away to avoid punch disfiguring workpiece Remaining position in addition to pressing.

Wherein, which is flat nick.

Wherein, which is arc incision, and the radian of the arc incision is 1/9 π.

There is the utility model the squeeze riveter upper mold for keeping away bit function to have the advantages that：

This squeeze riveter upper mold, design is simple, is skillfully constructed, at low cost, is capable of the function of the performance squeeze riveter of maximum possible, Satisfaction much has pressing for the special requirement that presses.

Description of the drawings

By reading the detailed description of hereafter preferred embodiment, it is various other the advantages of and benefit it is common for this field Technical staff will be apparent understanding.Attached drawing is only used for showing the purpose of preferred embodiment, and is not considered as to this practicality New limitation.And throughout the drawings, the same reference numbers will be used to refer to the same parts.In the accompanying drawings：

Fig. 1 shows the front view with the squeeze riveter upper mold for keeping away bit function according to the utility model embodiment.

Fig. 2 shows a kind of embodiment party with the squeeze riveter upper mold for keeping away bit function according to the utility model embodiment The bottom view of formula.

Fig. 3, which is shown, according to the utility model embodiment there is the another of the squeeze riveter upper mold for keeping away bit function to implement The bottom view of mode.

Specific embodiment

The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although this public affairs is shown in attached drawing The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here The mode of applying is limited.It is to be able to be best understood from the disclosure on the contrary, providing these embodiments, and can be by this public affairs The scope opened completely is communicated to those skilled in the art.

As shown in Figure 1, a kind of squeeze riveter upper mold for keeping away bit function, the head 10 of squeeze riveter upper mold 1 is to cut regular hexagon Polygonal except what is formed after a part, the side for cutting off formation is notch；A part is that can realize the part for keeping away position；Position is kept away to keep away Exempt from remaining position of punch disfiguring workpiece in addition to pressing.

As shown in Figures 2 and 3, to meet different use demands, which can be that flat nick or arc are cut Mouthful.Flat nick can to avoid when press be located proximate to bending edges when, the impact force to press impacts bending edges, arc incision Can to avoid when press be located proximate to convex closure hole when, the impact force to press impacts convex closure hole.When notch is arc, cut The radian of mouth is usually related to the distance in convex closure hole and the size in convex closure hole with the position that presses, in a specific embodiment In, the radian of arc incision is 1/9 π.

In addition, proved by many experiments, when the fixed bit of the jumper bar of trimming and upper mold and hexagon-head 10 is (in such as figure empty Shown in the delineation position of line) shortest straight line distance L be more than or equal to 0.4 centimetre when, will not to squeeze riveter press effect generate It influences, squeeze riveter can ensure the effect that normally presses.

It should be noted that this has the head shape and on-fixed for the squeeze riveter upper mold for keeping away bit function, or The various shapes such as circle, triangle, quadrangle.

To sum up, this squeeze riveter upper mold, design is simple, is skillfully constructed, at low cost, is capable of the performance squeeze riveter of maximum possible Function, satisfaction much have pressing for the special requirement that presses.

The above is only the preferable specific embodiment of the utility model, but the scope of protection of the utility model is not This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, can be readily occurred in Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with Subject to the scope of the claims.
