Abstract
The utility model relates to a prepressing lateral stress riveting fixture which comprises an upper die (1), a lower die (7), a guide sleeve (2) and a guide pin (5), the upper die (1) and the lower die (7) are columns with cavities inside, the guide sleeve (2) is sheathed in the cavity of the upper die (1) in a slide manner, the guide pin (5) is sheathed in the cavity of the lower die (7) in the slide manner, the guide sleeve (2) is sheathed on the guide pin (5), therefore, the main body of the prepressing lateral stress riveting fixture is formed. The prepressing lateral stress riveting fixture is characterized in that the external edge of a lower opening of the upper die (1) is provided with a circle of convex rings (9), a lower opening of the guide sleeve (2) is provided with a circle of bosses (8) matched with the pore diameter of a riveting piece, and an upper opening of the lower die (7) is provided with a groove (6) which is concentric with the guide pin (5). In riveting, a material is pressed down through the convex rings, and the riveted hole is supported outwards through an external support structure of the boss, so that metal material is fully led to move downwards so as to flow into a groove of a rivet nut.
Description
Technical field
This is practical newly to relate to a kind of prepressing type lateral stress riveting anchor clamps, belongs to the Machining Technology field.
Background technology
Common pressure-riveting process is exactly in the riveted joint process, is imposing under the ambient pressure situation, and the part that presses makes matrix material generation plastic deformation and clamp-ons in the pregroove marks ad hoc in self-clinching stud, the nut structure, thereby realizes the reliable connection of two parts.When for example adopting self-clinching stud, in use need on matrix, to open an aperture, the aperture is slightly larger than the diameter of thread; Self-clinching stud is put into hole; The employing equipment that presses is parallel uniformly at the head concora crush, because of the lower head of self-clinching stud is provided with the groove embossing, around the rivet that presses, produces distortion behind the matrix pressurized; With groove generation scuffing, be that self-clinching stud and matrix form annexation securely thereby make.
In the connection processing of sheet metal component, most of PEM standard riveting nut that adopts.But the use of PEM standard riveting nut has it restricted.It shows:
The first, like the hole of riveting nut at sheet metal component burr face (tearing zone face).The aperture of in general tearing zone face than the aperture of bright zone face come big, it is firm to cause riveting nut to press, the thrust test does not reach requirement, and the nut obscission in use often takes place.When tearing the aperture overgauge of zone face, press metal material flow behavior, there have not been enough metal materials to flow to the groove of nut root fully.
The second, if sheet metal component is a stainless steel material.This kind stainless steel sheet metal component material flowability can be limited, and it is not firm to use common die can cause riveting nut to press equally, and the thrust test does not reach requirement, and the nut obscission in use often takes place.Press stainless steel metal material flow behavior, riveting power strengthens and also can't make the stainless steel metal material flow to the groove of nut root.
Therefore, in the riveted joint process, guaranteeing that matrix generation plastic deformation has enough metal materials to flow in the preset groove of self-clinching nut root, is the key link that influences riveting quality, also is urgent problem in the production process.
Practical fresh content
This practical new purpose: be intended to propose a kind of prepressing type lateral stress riveting anchor clamps; It is simple in structure; Operation and maintenance is all very convenient, and the riveting nut that can make the hole of riveting nut tear zone face at sheet metal component is pressed into effectively securely, and reaches the requirement of nut thrust; Can flow in particular cases by effective firm riveting at the stainless steel metal material again.Effectively guarantee to press quality, can be applicable to the product of plurality of specifications and model simultaneously again.
This prepressing type lateral stress riveting anchor clamps; Comprise patrix 1, counterdie 7, guide pin bushing 2 and pilot pin 5, establish the cylinder of cavity in said patrix 1 is with counterdie 7, said guide pin bushing 2 slip caps are connected in patrix 1 cavity; Said pilot pin 5 slip caps are connected in counterdie 7 cavitys; Described guide pin bushing 2 is socketed on the pilot pin 5, constitutes the main body of prepressing type lateral stress riveting anchor clamps thus, it is characterized in that: described patrix 1 lower ending opening outer is provided with a circle protruding ring 9; Described guide pin bushing 2 lower ending opening places are provided with one and enclose the boss 8 that is complementary with the riveting parts aperture; Described counterdie 7 open upper end places are provided with the groove 6 concentric with pilot pin 5.
Can find out that through technique scheme the downward extrded material of protruding ring that is provided with by the patrix opening part in the riveting process outwards props up by riveted holes through the outer support formula structure that is arranged on the guide pin bushing convex platform; The lateral expansion that effectively suppresses base material; Fully the guide wire material moves downward in the groove that flows into self-clinching nut, in addition, has the guide pin bushing of different size boss through replacing; Can be applicable to the aperture of multiple sheet metal component; Effectively reduce the fraction defective of product, reduced the scrappage of doing over again, improved production efficiency.

The specific embodiment
Below we combine accompanying drawing and concrete instance to come this prepressing type lateral stress riveting anchor clamps are further specified, in the hope of set forth its structure and occupation mode more clearly.
This prepressing type lateral stress riveting anchor clamps as shown in the figure comprise patrix 1, counterdie 7, guide pin bushing 2 and pilot pin 5, establish the cylinder of cavity in said patrix 1 is with counterdie 7; Said guide pin bushing 2 slip caps are connected in patrix 1 cavity; Said pilot pin 5 slip caps are connected in counterdie 7 cavitys, and described guide pin bushing 2 is socketed on the pilot pin 5, constitute the main body of prepressing type lateral stress riveting anchor clamps thus; It is characterized in that: described patrix 1 lower ending opening outer is provided with a circle protruding ring 9, constitutes hold-down mechanism thus; Described guide pin bushing 2 lower ending opening places are provided with one and enclose the boss 8 that is complementary with the riveting parts aperture; The diameter of boss 8 is slightly less than by the aperture of riveting parts; Can make boss 8 stretch into, and fit tightly, constitute outer support mechanism thus with the perforate hole wall by in the perforate of riveting parts.
Described counterdie 7 open upper end places are provided with the groove 6 concentric with pilot pin 5.
The length of said pilot pin 5 is higher than the height of counterdie 7, and nut 4 all is socketed on the pilot pin 5 with guide pin bushing 2, plays positioning action.
In the riveting process; At first nut 4 is put into the groove 6 at counterdie 7 open upper end places through pilot pin 5; Secondly nut band odontoid upwards with the groove that is inserted in nut 4 by riveted holes after through pilot pin 5 of sheet metal component 3, is socketed in pilot pin 5 outsides with guide pin bushing 2 then; The boss 8 at guide pin bushing 2 lower ending opening places stretches into by in the riveted holes, at last patrix 1 is socketed in guide pin bushing 2 outsides and protruding ring 9 alignings that the patrix under shed goes out are carried out riveting operation by riveted holes.
Can find out that through technique scheme the protruding ring 9 downward extrded materials that are provided with by patrix 1 opening part in the riveting process outwards prop up by riveted holes through the outer support formula structure that is arranged on guide pin bushing 2 convex platforms 8; The lateral expansion that effectively suppresses base material; Fully the guide wire material moves downward in the groove that flows into self-clinching nut, in addition, has the guide pin bushing 2 of different size boss 8 through replacing; Can be applicable to the aperture of multiple sheet metal component; Effectively reduce the fraction defective of product, reduced the scrappage of doing over again, improved production efficiency.
