Abstract
The utility model relates to a riveting device without auxiliary materials, which comprises (1) an upper die and (2) a lower die, wherein the upper die comprises a fixing plate and a pressure plate which are fixedly connected as a whole, a bumper pad is arranged between the fixing plate and the pressure plate, the middle part of the whole is provided with a punching needle through hole in the vertical direction, and a punching needle is installed in the punching needle through hole; the lower die comprises a lower die plate, on which a base is fixed, the base is provided with a cylindrical lug boss, and a bottom core, of which the top surface is higher than the lug boss, is arranged corresponding to the lug boss. The part of the bottom core higher than the lug boss naturally forms a lower die hole corresponding to the punching needle, and the outer wall of the bottom core is sheathed with an elastic sleeve. The utility model has the advantages of simple structure and operational safety. The riveting device without auxiliary materials does not need auxiliary materials, can firmly rivet objects which need to be connected to a punch press by utilizing the objects and has low cost and high mass production effect.
Description
Technical field
The utility model relates to a kind of riveting set, particularly a kind of no auxiliary material riveting set.
Background technology
In the prior art,, generally be on the position of correspondence, to open riveted holes earlier, be that auxiliary material will be riveted each other with the rivet with riveting gun then, thereby make it to be fixed together for two or more objects of needs riveted joint.For example existing packaging for motorcar case liner support, being connected between its frame and frame, frame and the positions such as intermediate supports, just apply to above-mentioned connected mode in a large number, the packaging for motorcar case liner support that connects with this connected mode exists deficiency: 1. all will punch in the position that is connected of need riveted joints such as pair frame and frame, frame and intermediate supports, reduced the intensity of finished product self.2. the riveted joint process need carries out a large amount of drilling operations, and needs the people to measure rivet as auxiliary material, has increased cost greatly.3. should rivet operation and relevant operation thereof, and finish by operator's manual operations, it is low to produce effect in batches.
Summary of the invention
The purpose of this utility model just provides a kind of no auxiliary material riveting set, and it need not auxiliary material, and the object that needs each other to connect is riveted together.
The purpose of this utility model is to realize by such technical scheme, 1., patrix it includes:, it comprises fixed head and holding pad by an integral body of the affixed one-tenth of bolt, be provided with cushion pad between fixed head and the holding pad, this integral body middle part in the vertical direction is provided with towards the pin through hole, is equipped with towards pin in the pin through hole; 2., counterdie, it comprises lower bolster, base is fixed on the lower bolster, base is provided with a columniform boss, to being provided with the lower mold core that end face is higher than boss by boss, the part that lower mold core exceeds boss surround naturally with towards the corresponding nib down of pin, the outer wall of lower mold core is set with resilient sleeve.
To rivet two objects is that example illustrates use principle of the present utility model: at first with patrix and counterdie to be installed on the punch press towards the pin through hole mode relative with following nib, prepare to carry out riveted joint; Secondly among the two articles any one hole, to obtain riveted holes; Then two articles is placed respectively between patrix and the counterdie, wherein the object with riveted holes is in the below, and the riveted holes on it aligns with following nib; Start punch press at last, the object that does not bore riveted holes is impacted in drive towards pin, this object correspondence is being extruded generation deformation towards the position of pin under the effect of pin, deformation place extends to following nib on the boss along the riveted holes that is positioned at the bottom object, but boss is not had a deformability, and resilient sleeve has deformability, therefore this deformation place just pushes and promotes lower mold core to extending all around, form riveted joint, at this moment, be positioned at the deformation place of top object and be positioned at below object riveted joint.
Owing to adopted technique scheme, the utlity model has simple in structure, service-strong advantage, it need not auxiliary material, on punch press, utilizes object self will need firm being riveted together of object that connects each other, becomes originally low and produces the effect height in batches.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of patrix;
Fig. 3 is that Fig. 2 is along the cutaway view on the needle axis direction;
Fig. 4 is the structural representation of counterdie;
Fig. 5 is the cutaway view of A-A among Fig. 4.
Among the figure: 1. fixed head; 2. holding pad; 3. towards the pin through hole; 4. towards pin; 5. lower bolster; 6. base; 7. boss; 8. lower mold core; 9. descend nib; 10. resilient sleeve; 11. cushion pad.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is made further non-limiting description:
The utility model comprises by upper die and lower die: referring to accompanying drawing 1,2 or 3, patrix comprises fixed head 1 and the holding pad 2 by an integral body of the affixed one-tenth of bolt, be provided with cushion pad 11 between fixed head 1 and the holding pad 2, this integral body middle part in the vertical direction is provided with towards pin through hole 3, is equipped with towards pin 4 in the pin through hole; Participate in accompanying drawing 1,4 or 5, counterdie comprises lower bolster 5, base 6 is fixed on the lower bolster 5, base 6 is provided with a columniform boss 7, to being provided with the lower mold core 8 that end face is higher than boss by boss 7, the part that lower mold core 8 exceeds boss 7 surround naturally with towards pin 4 corresponding nibs 9 down, the outer wall of lower mold core 8 is set with resilient sleeve 10.
Referring to accompanying drawing 1,2 or 3, described number towards pin through hole 4 can be two, according to actual needs promptly, the number of the riveted joint of time processing moulding is set, and has reached the purpose that is riveted together that a plurality of objects are firm.
Referring to accompanying drawing 1,4 or 5, the number of described lower mold core 8 can be three, be beneficial between the lower mold core with one heart.Certainly, the number of lower mold core also can arbitrarily be set according to actual conditions.
Now in conjunction with the accompanying drawings 1,2,3,4 or 5, be that example illustrates use principle of the present utility model to rivet two objects: at first with patrix and counterdie to be installed on the punch press, to carry out the riveted joint preparation towards pin through hole 3 and following nib 9 relative modes; Secondly among the two articles any one hole, to obtain riveted holes; Then two articles is placed respectively between patrix and the counterdie, wherein the object with riveted holes is in the below, and the riveted holes on it aligns with following nib 9; Start punch press at last, drive is impacted the object that does not bore riveted holes towards pin 4, this object correspondence is being extruded generation deformation towards the position of pin under the effect of pin, deformation place extends to following nib 9 on the boss 7 along the riveted holes that is positioned at the bottom object, but boss 7 is not had a deformability, and resilient sleeve 10 has deformability, therefore this deformation place just pushes and promotes lower mold core 8 to extending all around, form riveted joint, at this moment, be positioned at the deformation place of top object and be positioned at below object riveted joint.
