Abstract
The invention relates to a rivet stem of a rivet specially used for riveting an electrical circuit board, a computer, aerospace, an integrated circuit and the like, in particular to a rivet stem of a non-fracture mute blind rivet. According to the technical scheme, the rivet stem of the non-fracture mute blind rivet is characterized in that a conical rivet stem head is integrally connected to the left end of a rivet stem rod, a small end of the rivet stem head is connected with the left end of the rivet stem rod, and a recess is arranged on a large end face of the rivet stem head at a position corresponding to the rivet stem rod. Both surfaces of a riveted workpiece can be smooth and can serve as front surfaces by the aid of the rivet stem, no rivet head drops out after riveting, and the rivet stem has the advantages of simplicity and convenience in operation, energy conservation, environmental protection, no noise, reliability in connection and the like.
Description
Technical field
The present invention relates to a kind of nail core that is used for riveting special purpose rivets such as electric appliance circuits plate, computer, Aero-Space and intergrated circuit, the nail core of the quiet pulling rivet of especially a kind of non-cracking.
Background technique
At special dimensions such as riveted joint electric appliance circuits plate, computer, Aero-Space, intergrated circuit.At present; Mostly what be used for realizing above-mentioned special riveted joint requirement is to adopt common self-plugging rivet and core rivet in midair; Core rivet complicated operation comes off the rubbish that causes electrical short-circuit or be difficult to clear up after the fracture of common self-plugging rivet nail core head easily in midair; And riveted joint back reverse side has the cydariform boss, and the two sides can not be equally bright and clean.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the existing technology, provide a kind of satisfy all bright and clean by riveted joint workpiece two sides, all can do that front, the no ailhead in riveted joint back drop out, easy and simple to handle, energy-conserving and environment-protective, noise free and connect the nail core of the quiet pulling rivet of reliable non-cracking.
According to technological scheme provided by the invention; The nail core of the quiet pulling rivet of said non-cracking; Left part at the nail core bar is connected with the nail core head; Said nail core head is a cone-shape, and the little head end of nail core head is connected with the left part of nail core bar, and the big end surface of following closely the nail core head of core bar position in correspondence offers depression.
Said nail core head is a cone shape, and the nail core head is coaxial setting with the nail core bar.
Said depression is a cone shape or spherical, and depression is coaxial setting with the nail core head.
The present invention rivets firmly, and it all is positive not staying nail core head, two sides after the staking, surface aesthetic, and energy-conserving and environment-protective, simple to operate, noise is low.Establish the riveted joint on the special dimensions such as being used for Aero-Space, computer circuit board especially.

Fig. 2 is the structural representation of the nail body that is used with nail core of the present invention.
Fig. 3 is nail core and the cooperating structure schematic representation of following closely body.
Fig. 4 is to use the phase diagram before the present invention rivets workpiece.
Fig. 5 is to use the phase diagram after the present invention rivets workpiece.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: the nail core of the quiet pulling rivet of this non-cracking; Be connected with nail core head 2.2 in the left part of nail core bar 2.1; Said nail core head 2.2 is a cone-shape; The little head end of nail core head 2.2 is connected with the left part of nail core bar 2.1, and the big end surface of following closely the nail core head 2.2 of core bar 2.1 positions in correspondence offers depression 2.3.
Said nail core head 2.2 is a cone shape, and nail core head 2.2 is coaxial setting with nail core bar 2.1.
Said depression 2.3 is a cone shape or spherical, and cave in 2.3 with follow closely core head 2.2 and be coaxial setting.
Nail core of the present invention in use; Need to cooperate and go up the nail body, said nail body comprises nail body body and nail body head, is connected with nail body head in an end of nail body body; Said nail body body is a hollow columnar; Nail body head is a cone-shape, and the vertex of a cone of nail body head is connected with nail body body, in nail body body and nail body head, has the nail core jack of integrated.
Described nail body body is a hollow cylindrical.Described nail body head is a cone shape.Said nail body body, nail body head are coaxial setting with nail core jack.
Said nail core jack comprises nail core jack left side section and the right section of nail core jack, and the right part of nail core jack left side section is connected with the left part of the right section of nail core jack; Nail core jack left side section is offered to the right along the axial direction of nail body body, and the right part of nail core jack left side section is positioned at the right side, left part of nail body head; The right section of nail core jack is conical, and the big opening end of the right section of nail core jack is towards the right side of nail body head.
Like Fig. 4, shown in Figure 5, when using the present invention to rivet, punching on first tabular body 3 to be riveted and second tabular body 4, the punching size on first, second tabular body is complementary with the size of nail body.The nail core bar 2.1 of nail core is followed closely in the nail core jack of body from the end insertion of nail body body, and made the nail core head 2.2 of following closely core be adjacent to the end face of nail body body, will follow closely core head 2.2 then and insert in the hole of first tabular body 3 and second tabular body 4 together with the nail body.The nail core is under the effect of riveting gun, and nail core head 2.2 compressing nail bodies make an end of nail body body expand into countersunk head shape, is adjacent on the counter sink of riveted plating, and nail core head 2.2 is owing to exist depression 2.3 to be out of shape to dwindle from follow closely the core jack and pull out.Riveted joint finishes, and simple to operate, energy-conserving and environment-protective, noise are low.
