Abstract
In a diffusion welding process for joining superimposed sheet metal parts by welding, part of the material of the metal sheets is locally upset at the weld by means of a stamp and a die, and forged perpendicularly to the plane of the metal sheets, causing the material of the sheet metal parts to join into a material flow. In order to achieve a sufficiently solid weld even when the parts to be joined are made of materials with a particular tendency to hardening or pre-hardened materials, the parts of the metal sheet surrounding the weld are pressed onto the die during welding with a force which is sufficient to prevent the material from yielding against the active direction of the stamp.
Description
The present invention relates to according to the diffusion welding process of the preamble of claim 1 and the device of the described method of enforcement of preamble according to Claim 8.
EP0,330, a kind of method and apparatus is disclosed among the 061B1, be used for the two-layer and more multi-layered planar metal sheet member that laminates mutually of engage pressure, wherein adopted the tool assembly that comprises drift and punch die, punch die have central anvil with respect to the vertical punch die spare that stretches out of anvil block working surface, punch die has therefrom shifted out and has defined and formed the chamber that engages therein in the side in the upsetting process.
In known engage pressure, the metal-sheet parts that connects is shifted and upsetting under situation about not heating subsequently simultaneously at the joint of selecting, exert pressure simultaneously and because the lateral flow of material, metal-sheet parts produces forward with the form of cup-shaped connector each other and interference fit is taken a seat.In this case, the volume that is positioned at the light sheet material of the joint under the punch die working face just has been shifted.For this reason, metallic sheet stock shifts out the plane of metal-sheet parts, the thickness of the roughly corresponding initial sheet metal of the basic thickness of the joint of generation.In further engage pressure process, the cup end of fastener, be clipped between drift working face and the anvil block by means of the lifting impulse force that increases, and realization has the upsetting operation of the material Radial Flow of bottom section, promptly so-called extension.Thickness at the bottom of the sheet metal reduces with respect to the thickness of initial sheet metal by upsetting, and this is essential so that produce necessary connection by extension.
In order to make this upsetting operation easier, the metal-sheet parts that engage can carry out local cutting along direction of displacement in the position that engages, therefore, in the upsetting operation, constraint for surplus material at the bottom of the fastener cup keeps the bigger free degree, and perhaps, this constraint reduces at least.Yet the cutting part that shortcoming is to engage in the operation has reduced the intensity at engage pressure place, and joint is not airtight, thereby not have the fastener of partial cut line be more desirable.
Up to now, for the metal-sheet parts of making by the stainless steel that is mainly austenite basic structure, adopt this engage pressure still not too economical.This point for other metal that in follow-up deformation processing, has especially tangible work hardening trend too, such as the very high stainless steel of alloy content, titanium or other prevulcanized metal such as high strength steel.Herein, the operating force that is caused by material that is used to engage in the metal forming has surpassed the joining tool load limit or has caused the latter to be lost efficacy after repeatedly engaging operation.
Yet, if the operating force that adopts is low excessively, the bearing capacity deficiency of joint.In addition, also can only in fastener, obtain not enough connection even it has been determined that the cold upsetting of maximum possible.Therefore the engage pressure of this metallic sheet stock only with metal-sheet parts cut line the time be only possible, and with relevant therewith shortcoming as cost, reduce to cause the remarkable increase of instrument access times by cutting operating force that line obtains.
First purpose of the present invention is to provide a kind of diffusion welding process of the universal class of mentioning during with beginning, even also can produce firm joint for comprising material with special work hardening trend or to be joined of prevulcanized material.
Second purpose of the present invention provides a kind of device that adopts this method.
First purpose of the present invention is that the feature by the characteristic of claim 1 realizes.
Second purpose of the present invention is that the feature by the characteristic of claim 8 realizes.
Whereby, by a kind of method is provided, realize the material that this method of effective connection is applied to have work hardening trend by using lower engaging force.Engage necessary power and reduce, thereby make instrument can bear this mechanical load.
According to the present invention, it has been determined that special in metallic sheet stock with serious work hardening because material material under compression is always attempted outwards to move and flow back to against the direction of drift action, so extension is difficult to carry out.In engaging operation, by pressurization on to be joined, can prevent this reverse flow, the extension that begins in this way, metallic sheet stock forces to form the connection fastener in the working region of punch die.For the material with special work hardening trend, this method also can form unprecedented good connection.
Because be positioned at bonding station metal-sheet parts on every side by certain defeating on punch die, this power no longer flows back to against the direction of drift action to the volume that material is pressed in the material that (to be punch die here) on the support to be joined greatly, and can realize so particularly: promptly the upset force that applies in early days in upsetting is used to form effective connection.Therefore, when considering the protection instrument, use less power and produce necessary degree of deformation, also can obtain enough bond strengths by advanced person's of the present invention mode at bonding station.Therefore, it is more economical that engage pressure becomes, and this is because the quantity of the contact of being finished by a joining tool increases significantly.
The pressure that acts on metal-sheet parts around bonding station is by power, and this power must be bigger than the adverse current power that engages the material of fastener in the operation.According to the present invention, determined that metal-sheet parts can not ftracture in engaging process if the size of pressure is set at least in the zone of drift, then pressure has surpassed adverse current power.
In addition, for example for smooth, even metal sheet member, the preferred value of pressure is approximately and only makes the fastener demoulding or prevent its 5 to 8 times in the crooked required power of displaced condition.
In addition, pressure preferably is applied on effective contact area of bonding station, and the size of this area is not left a trace on sheet metal for making applied pressure, and punch die spare can shift out when upsetting from the side.It is to be joined by the plastic deformation of folder that the pressure working face wants the enough big so that pressure load of gained can not cause, and as far as possible little again so that contact is in subtle position formation.
Have been found that metal forming can further be improved if metal-sheet parts engages under the temperature that is higher than environment temperature or tool temperature.In this case, suppose that 10 ℃ to the 50 ℃ temperature difference make the bearing capacity of contact improve for same engaging force.In the case, make fastener have the same bearer ability the time, engaging force will reduce nearly 15%.Such reason is reducing of work hardening, and this work hardening occurs in the situation of austenitic metal light sheet material especially.
Adopt press-bonding apparatus of the present invention, it is possible carrying out engage pressure for the metallic sheet stock with obvious work hardening trend, and the plastic deformation of drift and anvil block or the inefficacy of tool body can not take place.In this case, owing to prevented that crackle, the modular construction of drift and punch die from can make the bearing capacity of instrument higher.Therefore, set of tools can be born higher activating pressure.
For drift and the preferred high-strength material of anvil shaft is hard metal or high-strength ceramic.
In order to support drift and anvil shaft in the mode that is suitable for its pressure, they can be bearing on the flat support plate separately.
The shape of anvil block face is preferably the annular that is suitable for material and flows, flat chamfering, and can obtain outside light sheet material and the improved connection of same sheet metal bottom thickness.Simultaneously, this chamfering discharges the pressure at edge, thereby improved service life.
Drift and anvil shaft working face are star grinding pattern, and therefore, further raising and material flowed and improved their service life.
Further improvement of the present invention can obtain by following description and dependent claims.
