Wide contour successively squeezes out required part shape, has the advantages that no mould (or using simple mould) and low cost.For
The processing of the plates such as magnesium alloy, the titanium alloy of normal temperature hardly possible shaping must use hot progressive molding to realize.It is now right both at home and abroad
Temperature open-loop control method is mostly taken in the research of hot progressive molding, and to temperature, this forming parameter can not be controlled accurately.For reality
There is high cost, control complexity, deposit in the closed-loop control of existing temperature, it is necessary to temperature in use measurement apparatus, existing thermometry
The shortcomings of time delay.The present invention solves the problems, such as the temperature survey of hot progressive molding processing district, with simple in construction, cost
It is low, respond it is fast the advantages of.
【The content of the invention】
In order to overcome the above-mentioned technical difficulty that prior art is present, it is an object of the present invention to provide a kind of structure
Simply, the forming tool head easy to use with temperature measurement function, realizes the temperature scaling factor of hot progressive molding.
The present invention provides a kind of forming tool with temperature measurement function for progressive molding, and it includes forming tool
Handle, forming tool head, Infrared Thermocouple, collet and temperature controller；
The forming tool handle and forming tool head are equipped with endoporus；Forming tool handle and the endoporus phase of forming tool head
It is logical；The forming tool handle can be structure as a whole with forming tool head；The forming tool handle can be done with forming tool head
Into absolute construction, connected by welding or screw fixation method；If forming tool handle is not structure as a whole with forming tool head,
Forming tool head uses high temperature resistant, high-abrasive material such as hard alloy, and forming tool handle uses high intensity, high rigidity material such as bearing
Steel.
The forming tool handle is cylinder, is connected with machine tool chief axis, makes forming tool head keep fixing with machine tool chief axis
Position relationship；
The forming tool head is hemispherical or the cylinder with rounding, it is possible to achieve the light of forming tool head and plate
It is sliding to touch, improve the surface quality of formation of parts；
The Infrared Thermocouple be arranged on forming tool handle endoporus in, Infrared Thermocouple can through forming tool handle with into
The hole measuring plate temperature of shape tool heads；
The collet is arranged between forming tool handle and Infrared Thermocouple, and protection Infrared Thermocouple is not damaged by, every
The material of hot jacket can be with Ceramics, mica, glass fibre, asbestos, aerogel blanket；
The temperature controller is connected by wire with Infrared Thermocouple, and temperature controller gathers the data of Infrared Thermocouple
I.e. plate temperature, by contrasting the temperature of collection and the adjusted amount of processing temperature of setting and exporting to heater, is realized
Temperature scaling factor.
The present invention provides a kind of forming tool with temperature measurement function for progressive molding, the advantage is that structure letter
Single reasonable, cost is low；The Infrared Thermocouple can follow forming tool to move always, temperature near measurement plate deformed area,
Without additionally being controlled temperature measuring positions；The time delay that heat transfer is caused is not present using Infrared Thermocouple thermometric；
Direct measurement plate temperature, the error brought in the absence of equivalent measurement；Forming tool handle uses good rigidity, lower cost materials, into
Shape tool heads use high rigidity, resistant to elevated temperatures material, and performance is good, cost is low.
【Brief description of the drawings】
Fig. 1 is the overall structure diagram of one embodiment of the invention.
Label is described as follows in figure：
1. forming tool head；2. forming tool handle；3. Infrared Thermocouple；4. collet；5. wire；
6. temperature controller.
【Embodiment】
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following examples.
As shown in figure 1, a kind of forming tool with temperature measurement function for progressive molding of this example, including shaping
Tool heads 1, forming tool handle 2, Infrared Thermocouple 3, collet 4, wire 5 and temperature controller 6.The He of forming tool handle 2
Forming tool head 1 is equipped with endoporus；The forming tool handle 2 is made using low cost, high rigidity material, the forming tool head 1
With high rigidity, exotic material；The forming tool handle 2 and forming tool head 1 are by being welded to connect；The Infrared Thermocouple 3
In the hole of forming tool handle 2, the infrared ray that Infrared Thermocouple 3 is launched can pass through the endoporus of forming tool head 1；It is described every
Hot jacket 4 is arranged between Infrared Thermocouple 3 and forming tool handle 2, protects Infrared Thermocouple not by high temperature failure；
Forming tool is arranged on progressive molding machine tool chief axis, and plate is arranged on fixture for forming, starts lathe after processing
Main shaft drives the track of part contour mode of the forming tool along setting to move, and forming tool is constantly extruded plate.This hair
Forming tool in bright is applied in hot progressive molding, and plate is in integral high-temperature or deformed region localized hyperthermia, such as titanium alloy
Sheet Metal Processing temperature need to only measure deformed region temperature at 500 DEG C or so for temperature survey.It is red in forming tool of the present invention
Outer thermocouple can measure the local temperature of plate immediately below forming tool, measure the region of temperature and the distance of deformed region is
No more than the small distance of forming tool radius, the temperature equivalent deformation regional temperature measured can be used.Test Summary can be passed through
Go out the difference relationship of deformed region temperature and measured zone temperature, sheet metal deformation is obtained plus above-mentioned difference with measured zone temperature
The more accurate temperature in region.Temperature controller is obtained after deformed region temperature by contrasting the setting adjusted amount of processing temperature
And heater is sent to, heater adjusts temperature by adjusting heating power, finally realizes the closed-loop control of temperature.
