Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings:
High-strength aluminum alloy FSW tailor welded hot forming firing equipments designed by the present invention, including heating plate 1, material are pushed away
Send device 4, heating plate lowering or hoisting gear 5, temperature inspection and control module.Heater 2 and cooling water channel are provided with heating plate 1
3, cooling water channel 3 corresponds to the weld seam arrangement of required heated material, and heating plate is positioned opposite up and down at least provided with two pieces,
Material is clamped above and below in heating, by heat transfer heated material, thermal source is mainly provided by heater 2.The present invention's enters water
Mouth 6 is arranged on the bottom of whole equipment, and delivery port 7 is arranged on the top of whole equipment, and delivery port 7 and water inlet 6 are both connected to
Same water tank, water tank is connected with external source, and the replacing of cooling water can be carried out according to water temperature.Water inlet current are by pressurization
Reason, so the temperature that material commissure is pulled away can be calculated using below equation:Q=C1 × M × Δ T1=C2 × P ×
Δ T2, wherein, C1 is the specific heat capacity of material, and C2 is the specific heat capacity of water, and Δ T1 is the temperature difference of material and material commissure, Δ T2
It is the temperature difference of delivery port and water inlet, M is quality of material.Q is that current need the heat taken away in the unit interval.P is water quality
Measure flow, P=V × π d2/ 4, V are the speed of current, and d is cooling water channel diameter.Correspondence is calculated not by above-mentioned relational expression
Water velocity and temperature of the same material required under different solid solubility temperatures.Material pusher is by motor driven gear tooth
Bar transmission realization is moved forward and backward, and is promoted material to leave the segment distance of flat heated one, will so be facilitated crawl of the mechanical arm to material,
The startup of material pusher is determined by the temperature sensor in heater, the material when material, which is heated, to be completed
Pusher starts releases the gripping that the segment distance of heating platform one facilitates mechanical arm by material.And the mesh of heating plate lowering or hoisting gear
Be to clamp material when material is heated, after the completion of heating unclamp allow material pusher to release material, both controls
Signal processed both is from the temperature of material, both work compounds.Temperature inspection and control module mainly monitors the temperature of material, that is, controls
The temperature of heating rod processed makes temperature of charge grow steadily, while the temperature for obtaining material is used as material pusher and heating plate liter
The input signal of falling unit.
To increase the security of whole equipment operation process, the device external of the present invention is provided with the cover body with door,
Do not identified in accompanying drawing, the cover body with door had both facilitated material to pass in and out, be also prevented from the potential safety hazard that equipment is brought in high-temperature operation.
As shown in figure 1, it is 2024 aluminium alloy FSW tailor weldeds to be heated material, specific design of the present invention has three pieces of heating plates
1, formed two material interlayers, can thus heat simultaneously multi-sheets improve production efficiency, simultaneously because clamp up and down with
The mode of heat transfer will so make it that sheet material heating is more uniform, heats rapider to heat sheet material.
Water inlet 6 is connected in a large water tank with delivery port 7, and water inlet 6 has pressue device, and such current are in cooling water channel
It is middle to take away unnecessary temperature at a terrific speed.2024 aluminium alloy tailor weldeds are put into heating plate first when using the device
On, then start heating plate lowering or hoisting gear and be tightly clipped in sheet material between two pieces of heating plates 1, then heater starts rapid rise
Temperature heating sheet material, the optimal solid solubility temperature of 2024 aluminium alloys is 495 DEG C, and then the upper limit of design temperature is 495 DEG C, when temperature is arrived
Temperature is maintained 495 DEG C of insulation 40min up to heating is stopped at 495 DEG C, make the abundant solid solution of sheet material.Zero so processed
Part performance is just more excellent, however at this temperature the tissue of commissure will abnormal growth destroy its performance, and because
Heat around during transfer can be diffused into commissure, the temperature of commissure is raised to its deformation point, it is contemplated that in transfer
This period in increment, the temperature upper limit of commissure is set as 400 DEG C, but want the temperature of commissure reducing by 95
It is Q1 DEG C then to need the heat taken away, and Q1=C1 × M × (495-400), wherein Q1 is less than or equal to the heat Q2=C2 that current are taken away
× P × Δ T, and P=V × π d2/ 4, wherein C=0.88 × 1000J/ ﹙ Kg DEG C), the quality of weld seam is M=ρ V=2.7g/cm3
× 40mm × 10mm × 3mm=0.1324g, then Q1=C1 × M × 95=110.6864J.Then Q2 >=110.6864J but water tank
In water be 25 DEG C of normal temperature, the water temperature for measuring exit is 75 °, then Δ T=50.And C2=4.2 × 103J/ (kg DEG C), P=
V×πd2/ 4, wherein a diameter of 6cm of each water channel there are two again, suitable water velocity V=0.4m/s has been obtained by calculating,
Sheet material can keep 495 DEG C of progress solid solutions in such a state, and the temperature of commissure can be less than 400 DEG C again.In temperature sensor
When detecting sheet material temperature and having reached solid solubility temperature, control end obtains signal, maintains this temperature to heat always, and reaches predetermined
During time 40min, giving heating plate lowering or hoisting gear one signal, heating plate lowering or hoisting gear unclamps sheet material, while material pushes dress
Put and also have received the enabling signal from control end, material is released into the gripping that the segment distance of heating plate one facilitates mechanical arm, then
Gripped by mechanical arm to subsequent processing workbench.Whole cooling water pipe is all ceaselessly to flow and be connected to a large water tank,
Water in water tank is also not to be parked in replacing, is accumulated gradually decrease cooling-down effect to prevent water temperature.
The beneficial effect of generation of the present invention is:The present invention is due to consideration that weld seam under solid solubility temperature easily causes crystalline substance
Body abnormal growth influences its structure property, has installed cooling water channel additional in commissure to reduce the temperature at this, so as to ensure blank
Forming property and drip molding quality during following process.It is to be in close contact that the present invention, which uses sheet material and heating plate, again
, compared to traditional mode of heating, the heating of this mode of heating is rapider, heat it is more uniform, and energy utilization more
Fully.Due to the arrangement achieves the cooling of ad-hoc location, so as to realize the gradient-heated of sheet material.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these changes and conversion should all belong to the protection domain of appended claims of the present invention.
