Abstract
A kind of novel broaching tool, belongs to metallic article process unit field.Existing on the panel of chain broaching tool there is complex operation step, the more high defect of production cost.The utility model comprises handle of a knife, handle of a knife upper end arranges the broaching tooth of multiple its outer peripheral face of annular spread, handle of a knife top is that upper end is little, lower end is large, the cross section at its top is in the polygon be at least made up of five limits, broaching tool is installed on after on pressing equipment, first the plate contact of handle of a knife top and chain realizes the punching of counter plate, and the broaching tooth counter plate then on handle of a knife is processed, thus realizes shaping required hole on panel.The top of broaching tool is arranged to that upper end is little by the utility model, lower end is large, and during work, broaching tool can first to the panel punching on chain, then by its broaching tooth, broaching tool work is carried out to hole, thus can procedure of processing be reduced, make the hole one-shot forming of panel, improve the production efficiency of broaching tool.
Description
Technical field
The utility model belongs to metallic article process unit field, especially relevant with the broaching tool in the hole on a kind of processing chain panel.
Background technology
Panel on chain needs to carry out punching to it, thus on panel, be processed to form required hole.Existing process of processing on panel is that first panel is carried out punching by pressing equipment by blind rivet, after blind rivet counter plate carries out punching, hole is not often conglobate, if directly installation shaft is behind this hole, due to axle and hole wall contact only some, such axle in the course of the work with hole wall discontinuity, axle is easily caused to damage, thus reduce the service life of axle, so need work hole being carried out again to broaching tool under normal circumstances, as shown in Figure 1, existing broaching tool is the broaching tooth 2 arranging multiple annular spread on the outer peripheral face of its handle of a knife 1, by the broaching of broaching tool to hole, hole is made to become deformation circle, but such processing mode is completed by two steps, indirectly add the production time of panel processing, reduce the working (machining) efficiency of broaching tool counter plate, and need to be equipped with blind rivet and broaching tool simultaneously, add the production cost of enterprise.
Utility model content
The purpose of this utility model is intended to overcome existing broaching tool exists on the panel of chain complex operation step, the more high defect of production cost, provides the novel broaching tool that a kind of time processing is shaping, production cost is lower.
For this reason, the utility model is by the following technical solutions: a kind of novel broaching tool, comprise handle of a knife, handle of a knife upper end arranges the broaching tooth of multiple its outer peripheral face of annular spread, and handle of a knife top is that upper end is little, lower end large, and the cross section at its top is in the polygon be at least made up of five limits, broaching tool is installed on after on pressing equipment, first the plate contact of handle of a knife top and chain realizes the punching of counter plate, and the broaching tooth counter plate then on handle of a knife is processed, thus realizes shaping required hole on panel.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristic.
Described broaching tool is provided with multiple on pressing equipment, and broaching tool is fixed on pressing equipment by installed part, thus can carry out porous processing by counter plate simultaneously.
The length of side on described polygonal every bar limit is equal.
The cross section at described handle of a knife top is pentagon.
Use the utility model can reach following beneficial effect: the top of broaching tool is arranged to that upper end is little, lower end is large by the utility model, during work, broaching tool can first to the panel punching on chain, then by its broaching tooth, broaching tool work is carried out to hole, thus can procedure of processing be reduced, make the hole one-shot forming of panel, improve the production efficiency of broaching tool.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing broaching tool.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is A-A place cross-sectional schematic in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Fig. 2-Fig. 3, the utility model comprises handle of a knife 1, and handle of a knife upper end arranges the broaching tooth 2 of multiple its outer peripheral face of annular spread, and handle of a knife top 3 is little in upper end, lower end is large, the cross section at handle of a knife top 3 is in the polygon be made up of five limits, and the length of side on polygonal every bar limit is equal; Broaching tool is provided with multiple on pressing equipment, broaching tool is fixed on pressing equipment by installed part, thus porous processing can be carried out by counter plate simultaneously, first handle of a knife top 3 and the plate contact of chain realize the punching of counter plate, then broaching tooth 2 counter plate on handle of a knife is processed, thus realizes shaping required hole on panel.
The top of broaching tool is arranged to that upper end is little by the utility model, lower end is large, and during work, broaching tool can first to the panel punching on chain, then by its broaching tooth, broaching tool work is carried out to hole, thus can procedure of processing be reduced, make the hole one-shot forming of panel, improve the production efficiency of broaching tool.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
