Abstract
The present invention provides seamless riveted type corrugated sheet rivets, belong to rivet technology field.It solves the problems such as existing riveting shakiness of existing rivet is even with rear deformation or fracture.Originally seamless riveted type corrugated sheet rivet, including nail seat and nail rod, one end of the nail rod and nail seat integrally connected, the nail rod other end is equipped with the frustum of a cone formed by cold-heading processing, the nail rod sets gradually the first fastening part, connecting portion, the second fastening part of cylinder of cylinder from nail seat to frustum of a cone direction, and the diameter of section of first fastening part is more than the diameter of section of the second fastening part.The present invention has many advantages, such as the service life that riveting parts are close to, are improved to rivet, and improves the quality of product.
Description
Technical field
The invention belongs to rivet technology fields, refer in particular to a kind of seamless riveted type corrugated sheet rivet.
Background technology
At present, the corrugated sheet rivet used on clutch driven disk for automobile makes there is riveting shakiness or even in clutch
Phenomena such as with rear generation rivet deformation or fracture.Tracing it to its cause mainly has at 2 points:
1. corrugated sheet rivet is typically small, need to meet in its riveted friction plate and corrugated sheet into respective riveted holes, this
The aperture requirement of sample clearance fit is just bigger, and consequence is to make riveting region can not turgor the phenomenon that causing riveted unstable.
2. structure is all relatively simple in the corrugated sheet rivet used in the current country, swollen discontented in order to solve the problems, such as, setting
Timing rivet generally uses non-chamfering formula structure.Thus generate three hidden danger of quality:
One is if friction plate and the rivet bore dia of corrugated sheet reduce:Since corrugated sheet rivet is processed by cold-heading, it is molded
Rear rod portion can carry the burr of scissors blank, if converted products gauge diameter tolerance on the upper side, this can lead to not be put into riveting
Kong Zhong causes rivet to scrap.
If the second is friction plate and the increase of the rivet bore dia of corrugated sheet:Corrugated sheet rivet can be directly placed into riveted holes
In, it but if converted products gauge diameter tolerance on the lower side, can not just be solved the problems, such as after riveting swollen discontented, this can cause to rivet
Shakiness in addition after clutch use generate rivet deformation or fracture phenomena such as, clutch drived disk assy is caused to damage.
If the third is the diameter tolerance of rivet is reduced or reduces corrugated sheet and friction plate hole tolerance, processing
In can not fully achieve, part scrap rate is caused to increase.
The content of the invention
Solved the object of the present invention is to provide one kind riveted existing for corrugated sheet rivet it is unstable even with rear deformation or
Phenomena such as fracture, while rivet is avoided to scrap, realize the corrugated sheet rivet for saving production cost.
The object of the present invention is achieved like this:
Seamless riveted type corrugated sheet rivet, including nail seat and nail rod, one end and the nail seat integrally connected of the nail rod, feature
It is:The nail rod other end is equipped with the frustum of a cone formed by cold-heading processing, and the nail rod is from nail seat to the frustum of a cone
Direction sets gradually the first cylindrical fastening part, connecting portion, the second fastening part of cylinder, and first fastening part is cut
Face diameter is more than the diameter of section of the second fastening part.
The diameter of section of the first above-mentioned fastening part is d1, and the diameter of section of the second fastening part is d2, the ︱ d1 ︱-︱
D2 ︱ ≈ 0.1mm.
Above-mentioned connecting portion is the frustum of a cone, and the busbar of connecting portion and the angle of its bottom surface are acute angle.
Above-mentioned connecting portion is the frustum of a cone, and the busbar of connecting portion and the angle of its bottom surface are acute angle.
The axial length of the first above-mentioned fastening part is 0.8 ~ 1.2mm, the axial length of the second fastening part for 1.4 ~
1.8mm。
The present invention is prominent and beneficial compared with prior art to be had the technical effect that:
1st, the present invention can reduce the quality risk not being close to due to rivet caused by processing of generally taking the lead, so as to improve riveting
The service life of fitting, and improve the quality of product.
2nd, the present invention is final to realize so as to improve the angle of inclination of rivet bar portion by improving cold-heading product forming technique
Rivet can all be fited when pressing with riveted holes.
3rd, the present invention makes rivet first in the first mould using being molded twice during cold-heading molding by cone angle processing
The first one-step forming of bar portion, then passes through the squeezing action in the second mould so that rivet bar portion forms a size diameter and inclination
The region at angle.
Description of the drawings
Fig. 1 is the structure sectional view of the present invention.
Fig. 2 is the top view of the present invention.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig. 1-2:
Seamless riveted type corrugated sheet rivet, including nail seat 1 and nail rod 2, one end and the nail seat integrally connected of the nail rod, nail rod
The other end be equipped with by cold-heading processing formed the frustum of a cone 3, the nail rod from nail seat to frustum of a cone direction successively
The first cylindrical fastening part 4, connecting portion 5, the second cylindrical fastening part 6 are set, and the section of first fastening part is straight
Footpath is more than the diameter of section of the second fastening part.By cold-heading molding instead of machining, strength-weight ratio is also preferable.
The diameter of section of the first above-mentioned fastening part is d1, and the diameter of section of the second fastening part is d2, the ︱ d1 ︱-︱
D2 ︱ ≈ 0.1mm.
Above-mentioned connecting portion is the frustum of a cone, and the busbar 50 of connecting portion and the angle of its bottom surface 51 are acute angle.
The axial length of the first above-mentioned fastening part is 0.8 ~ 1.2mm, the axial length of the second fastening part for 1.4 ~
1.8mm。
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore:It is all according to
The equivalence changes that structure, shape, the principle of the present invention is done, should all be covered by within protection scope of the present invention.
