Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments:
High-strength aluminum alloy FSW tailor welded hot forming heating equipment designed by the present invention, including heating plate 1, material push away
Send device 4, heating plate lifting device 5, temperature inspection and control module.Heating device 2 and cooling water channel are provided in heating plate 1
3, the weld seam that cooling water channel 3 corresponds to required heated material is arranged, heating plate is positioned opposite up and down at least provided with two pieces,
Clamp material up and down when heated, by heat transfer heated material, heat source is mainly provided by heating device 2.Of the invention enters water
The lower part of whole equipment is arranged in mouth 6, and the top of whole equipment is arranged in water outlet 7, and water outlet 7 and water inlet 6 are both connected to
Same water tank, water tank are connected to external source, and the replacement of cooling water can be carried out according to water temperature.Water inlet water, which flows through, is overpressurized place
Reason, is calculated so the temperature that material commissure is pulled away can use following formula: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 water outlet and water inlet, M is quality of material.Q is the heat that water flow needs to take away in the unit time.P is water quality
Measure flow, P=V × π d2/ 4, V are the speed of water flow, and d is cooling water channel diameter.It is calculated and is corresponded to not by above-mentioned relational expression
Same material required water velocity and temperature under different solid solubility temperatures.Material pusher is driven by a motor gear teeth
Item transmission, which is realized, to move forward and backward, and pushes material to leave flat heated a distance, will facilitate crawl of the mechanical arm to material in this way,
The starting of material pusher is determined by the temperature sensor in heating device, the material when material, which heats, to be completed
Material release heating platform a distance is facilitated the clamping of mechanical arm by driving means starting.And the mesh of heating plate lifting device
Be to clamp material in material heating, unclamped after the completion of heating and material pusher allowed to release material, the control of the two
Signal processed both is from the temperature of material, the two work compound.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 obtaining the temperature of material as material pusher and heating plate liter
The input signal of falling unit.
For the safety for increasing whole equipment operation process, device external of the invention is provided with the cover with door,
It is not identified in attached drawing, the cover with door had both facilitated material to pass in and out, and was also prevented from equipment bring security risk in high-temperature operation.
As shown in Figure 1, being heated material is 2024 aluminium alloy FSW tailor weldeds, the present invention, which specifically designs, three pieces of heating plates
1, form two material interlayers, can thus heat simultaneously multi-sheets improve production efficiency, simultaneously because up and down clamp with
The mode of heat transfer is incited somebody to action in this way to heat plate so that plate heating is more uniform, and heating is rapider.
Water inlet 6 is connected in a large water tank with water outlet 7, and water inlet 6 has pressurizing device, and such water flow is in cooling water channel
It is middle to take away extra 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 lifting device and be tightly clipped in plate between two pieces of heating plates 1, then heating device starting rises rapidly
Temperature heating plate, the best solid solubility temperature of 2024 aluminium alloys are 495 DEG C, and then the upper limit of set temperature is 495 DEG C, when temperature arrives
Stopping heating when up to 495 DEG C makes temperature maintain 495 DEG C of heat preservation 40min, is dissolved plate sufficiently.Zero processed in this way
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, so that the temperature of commissure is raised to its deformation point, it is contemplated that shifting
This period in increment, the temperature upper limit of commissure is set as 400 DEG C, however to the temperature of commissure is reduced by 95
DEG C then needing the heat taken away is Q1, Q1=C1 × M × (495-400), and wherein Q1 is less than or equal to the heat Q2=C2 that water flow is 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 however water tank
In water be 25 DEG C of room temperature, the water temperature for measuring exit is 75 °, then Δ T=50.C2=4.2 × 10 again3J/ (kg DEG C), P=
V×πd2/ 4, wherein each water channel diameter be 6cm again there are two, suitable water velocity V=0.4m/s has been obtained by calculation,
Plate is able to maintain 495 DEG C and is dissolved in such a state, and the temperature of commissure can be lower than 400 DEG C again.In temperature sensor
When detecting that plate temperature has reached solid solubility temperature, control terminal obtains signal, this temperature is maintained to heat always, and reaches predetermined
When time 40min, one signal of heating plate lifting device is being given, heating plate lifting device unclamps plate, while material push dress
It sets and also has received the enabling signal from control terminal, material release heating plate a distance is facilitated to the clamping of mechanical arm, then
It is clamped 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 replacement, accumulates gradually to prevent water temperature and weakens cooling effect.
The beneficial effect of generation of the invention is:The present invention is due to consideration that weld seam under solid solubility temperature be easy to cause crystalline substance
Body abnormal growth influences its structure property, has installed cooling water channel additional in commissure to reduce the temperature at this, to guarantee blank
Forming property and drip molding quality during following process.The present invention is to be in close contact using plate and heating plate again
, compared to traditional heating method, the heating of this heating method is rapider, and heating is more uniform, and the utilization of energy is more
Sufficiently.Since the arrangement achieves the coolings of specific position, to realize the gradient-heated of plate.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these changes and transformation should all belong to the protection domain of appended claims of the present invention.
