Abstract
The invention discloses a female die for a rivet installation die. The female die comprises a lower die holder, a female die body, a locating column and a spring, wherein the female die body is fixedly connected to the lower die holder through screws, the locating column is arranged in the female die body, and the upper end of the locating column is semicircular; the upper end of the spring is fixedly connected to the lower end surface of the locating column, and the other end of the spring is fixedly connected to the upper end surface of the lower die holder. The locating column moves up and down relative to the female die body under the action of the spring; when the spring is in an initial state, the semicircular portion of the locating column is higher than the upper end surface of the female die body, and an elastic material is arranged on the semicircular surface of the locating column. The female die for the rivet installation die is used for being installed on the rivet installation die of a ribbon retainer, and is simple in structure and reasonable in design, and riveting quality is effectively improved; due to the fact that the elastic material is arranged on the upper end surface of the locating column, the phenomenon that the ribbon retainer is pressed to deform in the working process can be avoided, production efficiency is improved, and quality of bearing products is guaranteed.
Description
Technical field
The present invention relates to a kind of master structure of binding mould, refer in particular to the binding mould master mold that a kind of riveted is effective, production efficiency is high.
Background technology
Deep groove ball bearing is made up of ribbon retainer, rolling element, inner ring and outer ring.Ribbon retainer through riveted, will make two halves retainer rivet securely and plays maintenance effect when assembling.Prior art is when assembling bearing, and need to be dialled by ball even after dress ball, buckle two halves retainer, then inserted one by one in the rivet hole of retainer by rivet, button upper rivet model, deliver to punching press in punch press, efficiency is low.The ribbon retainer of prior art, in process of production, often generation riveting is askew, riveting inclined and lack nail phenomenon, affects production efficiency and the product quality of bearing.Therefore be necessary to improve each parts of binding mould, solve that riveting is askew, riveting partially and lack the problems such as nail, raising assembly quality and end product quality.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of binding mould master mold.
Technical solution of the present invention is achieved in that a kind of binding mould master mold, comprises die shoe, die, locating dowel and spring; Described die is fixedly connected on die shoe by screw; Described locating dowel is arranged in die, and its upper end is semicircle shape; The upper end of described spring is fixedly connected on the lower surface of locating dowel, and the other end is fixedly connected on the upper surface of die shoe; Under the action of the spring, the relative die of described locating dowel moves up and down; When spring in a state of nature time, the semicircle shape part of described locating dowel exceeds the upper surface of die; The semicircle shape of described locating dowel is provided with elastomeric material on the surface.
Preferably, described elastomeric material is rubber, and its thickness is 1-2mm.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Binding mould master mold of the present invention, structure is simple, reasonable in design, for installing ribbon retainer binding mould, monolithic ribbon retainer compresses tight rivet, complete the ribbon retainer hole after binding and rivet forms interference fit, effectively prevent and lack nail phenomenon, decrease waste product, the upper surface of described locating dowel is semicircle shape, and upper surface is provided with elastomeric material, such design, effectively can prevent from adding man-hour ribbon retainer to be crushed out of shape, therefore improve deep groove ball bearing riveting quality and assembly work efficiency, save cost, improve production efficiency, ensure that bearing products quality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of binding mould master mold of the present invention;
Accompanying drawing 2 is with binding mould master mold working state schematic representation of the present invention;
Wherein: 1, die shoe; 2, die; 3, locating dowel; 4, spring; 5, elastomeric material; 6, patrix handle; 7, punch; 8, nail pressing bar; 9, backstay.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The structure of binding mould master mold of the present invention as shown in Figure 1, comprises die shoe 1, die 2, locating dowel 3 and spring 4; Described die 2 is fixedly connected on die shoe 1 by screw; Described locating dowel 3 is arranged in die 2, and its upper end is semicircle shape; The upper end of described spring 4 is fixedly connected on the lower surface of locating dowel 3, and the other end is fixedly connected on the upper surface of die shoe 1; Under the effect of spring 4, described locating dowel 3 relatively die 2 moves up and down; When spring 4 in a state of nature time, the semicircle shape part of described locating dowel 3 exceeds the upper surface of die 2; The semicircle shape of described locating dowel 3 is provided with elastomeric material 5 on the surface, prevents ribbon retainer to be crushed out of shape when being conducive to work.
Accompanying drawing 2 is that master mold of the present invention is mounted to the working state structure schematic diagram after binding mould with corresponding male model, the operation principle of its binding mould is: when upper, counterdie separately, monolithic ribbon retainer is placed on die 2, located by locating dowel 3, patrix 6 under the effect of power-equipment, punch 7 is driven to move down, rivet is pressed in the rivet hole of ribbon retainer, form interference fit, complete mono-sheet to mark closely, then patrix drives on punch 76 and moves, the monolithic ribbon retainer installing rivet is upspring by locating dowel 3 under the restoring force effect of spring 4, conveniently take off.
Further instruction, described elastomeric material 5 is rubber, and its thickness is 1-2mm, according to size and the rigidity of ribbon retainer product to be processed, designs suitable thickness.
Binding mould master mold of the present invention, structure is simple, reasonable in design, for installing ribbon retainer binding mould, monolithic ribbon retainer compresses tight rivet, complete the ribbon retainer hole after binding and rivet forms interference fit, effectively prevent and lack nail phenomenon, decrease waste product, the upper surface of described locating dowel is semicircle shape, and upper surface is provided with elastomeric material, such design, effectively can prevent from adding man-hour ribbon retainer to be crushed out of shape, therefore improve deep groove ball bearing riveting quality and assembly work efficiency, save cost, improve production efficiency, ensure that bearing products quality.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
