Abstract
The invention discloses a riveting method, which comprises the following steps of: pre-treating two metal elements to be riveted by using a traditional mechanical processing method of stamping or lathing, forming a clearance at riveting points of the two metal elements to be riveted, and applying pressure to the riveting points of the two metal elements to be riveted by combined stamping and riveting so as to mutually extrude the two metal elements and fill the clearance to form firm connection. The riveting method is a two-step method combining pre-treatment performed by adopting the traditional mechanical processing method and cavity angle-expansion filling, wherein the metal elements to be riveted are pre-treated with certain shapes by using the traditional mechanical processing method of stamping or lathing to form convenient riveting points, and then the two metal elements which have a cavity before combination are mutually extruded by combined stamping and riveting under the action of stamping to fill the cavity so as to form an inverted locking structure filled partially or fully, so the purpose of firm riveting is fulfilled.
Description
Technical field
The invention belongs to the Machining Technology field, be specifically related to the clinching method between the hardware of tool definite shape.
Background technology
For the permanent riveting process of metal that need satisfy outward appearance and fixing requirement simultaneously, always there is very high difficulty.Existing traditional handicraft adopts the riveting of rising of means of spot welds or straight shape, and not only complex technical process, production efficiency are low, and firm weak effect, electroplates riveted joint position, back appearance poor.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of firm and reliable connection, production efficiency height are provided, can effectively cut down the consumption of energy and the rise clinching method at angle of hole economical with materials, that be particularly suitable for loudspeaker rear plate manufacturing in the electron trade.
The objective of the invention is to be achieved through the following technical solutions:
A kind of clinching method is characterized in may further comprise the steps:
Utilize traditional machining process of punching press or machined into that two hardwares to be riveted are carried out preliminary treatment earlier, riveting point at two hardwares to be riveted forms the space, at this moment, described preliminary treatment is to adopt the method for car system to make boss in riveting point, metal cartridge to be riveted bottom and get out through hole therebetween, on metal base plate to be riveted, utilize again the cooperation of upper die and lower die stamp out up-small and down-big have subtended angle and with the corresponding flared hole of metal cartridge bottom boss; Exert pressure and make the extruding and fill the space and form firm connection mutually of two hardwares in the riveting point that is riveted on two hardwares to be riveted by combined pressing again, this moment exerts pressure and makes the extruding and fill the space to form firm connection be to utilize the cooperation of the boss of metal cartridge and metal base plate and flared hole both to be combined and put into mould to carry out knockdown punching press riveted joint mutually of two hardwares in the described riveting point that is riveted on two hardwares to be riveted by combined pressing, this moment, the boss of metal cartridge produced crimp because of pressurized, deformation direction is the center line that deviates from boss, this boss is subjected to the obstruction of metal base plate when crimp simultaneously, forces its deflection to be filled in the space between metal base plate flared hole and the metal cartridge boss and the reversal of the natural order of things locking structure that the formation gap is filled up or all filled up.
The present invention fills the clinching method of the two step method that combines owing to adopt traditional machining process to carry out preliminary treatment and the hole angle of rising, earlier the hardware that will rivet is mutually carried out the preliminary treatment of definite shape by the machining mode of utilizing traditional punching press or machined into, form behind the riveting point easily again and to make two hardwares that have the hole before the combination be subjected to punching press to influence mutual extrusion packing hole by the combined pressing riveted joint to form the reversal of the natural order of things locking structure that part is filled up or all filled up, reach the purpose of firm riveted joint.And processing and making process is simple, and whole process can realize automatic continuous production, the production efficiency height, and can effectively cut down the consumption of energy and economical with materials, directly reduced manufacturing cost, be particularly suitable for the making of loudspeaker rear plate in the electron trade.
Describe work implementation procedure of the present invention in detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the realization flow figure of embodiment of the present invention.
The specific embodiment
As shown in Figure 1, clinching method of the present invention may further comprise the steps: utilize traditional machining process of punching press or machined into that two hardwares to be riveted are carried out preliminary treatment earlier, form space 3 in the riveting point of two hardwares to be riveted, exert pressure and make the extruding and fill space 3 and form firmly and connect mutually of two hardwares in the riveting point that is riveted on two hardwares to be riveted by combined pressing again.Wherein according to the shape of hardware to be riveted and preliminary treatment that characteristic is carried out and the appearance performance requirement after the combination punching press riveted joint, the present invention includes but be not limited to following this embodiment, as shown in Figure 1, above-mentioned clinching method can be may further comprise the steps: adopt the method for car system or forge hot or cold forging to make boss 13 and get out through hole 14 therebetween earlier in riveting point, metal cartridge to be riveted 1 bottom, on metal base plate to be riveted 2, utilize again the cooperation of patrix 51 and counterdie 52 stamp out up-small and down-big have subtended angle and with metal cartridge 1 bottom boss 13 corresponding flared hole 23, utilize the cooperation of the boss 13 of metal cartridge 1 and metal base plate 2 and flared hole 23 both to be combined and put into mould then and carry out knockdown punching press riveted joint, this moment, the boss 13 of metal cartridge 1 produced crimp because of pressurized, deformation direction is the center line that deviates from boss 13, this boss 13 is subjected to the obstruction of metal base plate 2 when crimp simultaneously, forces its deflection to be filled in the space 3 between the boss 13 of metal base plate 1 flared hole 23 and metal cartridge 1 and the reversal of the natural order of things locking structure that formation space 3 parts are filled up or all filled up.
