Machine for shrinking of the present utility model by draw unit head is heated, but makes the to be processed magnesia pipe that is in the main shaft content cavity be in best machining state.
In an embodiment of the present utility model, described heater comprises the hot oil inlet that is positioned at upper end, described draw unit head periphery, be positioned at the oil export of the peripheral lower end of described draw unit head, link to each other with hot oil inlet and oil is sprayed onto the nozzle of described draw unit head and wraps up the thermal insulation layer of described draw unit head.
In another embodiment of the present utility model, described heater comprises electric heating tube of being located in the described draw unit head and the thermal insulation layer that wraps up described draw unit head.
In another embodiment of the present utility model, described heater promptly comprises above-mentioned oily heating arrangement, also comprises above-mentioned electric heating tube structure.
Described heater also comprises the electrical heating coil of being located at described opening periphery.
This structure is processed preceding preheating can for magnesia pipe to be processed, thereby be improved working (machining) efficiency.
Described heater also comprises and is used for carrying out the cooling body of cooling processing to being exposed to that section main shaft outside the described thermal insulation layer.Described cooling body comprises the cooling water inlet that is arranged at upper end, described main shaft periphery, is positioned at the water out of the peripheral lower end of described main shaft and the nozzle that Jiang Shui is sprayed onto described main shaft, and described nozzle links to each other with cooling water inlet.
This structure can be guaranteed that the other parts of machine for shrinking are in normal operating temperature state, and avoid the negative effect that described heater brings.
Compare with prior art, machine for shrinking of the present utility model can satisfy the draw processing needs to magnesia pipe simply, conveniently and efficiently, and making the magnesia tubing that is out of shape be used for bicycle production becomes possibility.
Description of drawings
Fig. 1 is magnesia pipe before draw processing and the back profile effect schematic diagram of processing;
Fig. 2 is the positive cross-sectional schematic of machine for shrinking embodiment of the present utility model.
The specific embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in each accompanying drawing.
As shown in Figure 1, the structure of magnesia pipe 100, comprise first pipe shaft 101 and second pipe shaft 102, wherein second pipe shaft 102 adopts machine for shrinking embodiment of the present utility model to handle, as seen, its outline 102a before draw processing is identical with the outline of first pipe shaft 101 for second pipe shaft 102, and integral body is a straight tube, and presents the descending Taper Pipe shape that gradually changes at draw processing back its outline 102b.
Machine for shrinking embodiment of the present utility model as shown in Figure 2 comprises frame 1, table top 2, driving mechanism 3, main shaft 4, draw unit head 5, cooling water inlet 6, coolant outlet 7, be located at the pipe cavity volume 8 to be processed in the main shaft, hot oil inlet 9, oil export 10, Electrothermal ring 11 is located at electric heating tube 12 and the thermal insulation layer 13 grade structure members of parcel draw unit head in it in the draw unit head.Main shaft 4 is driven by driving mechanism 3 and rotates, thereby mechanical function is taken place and carries out draw processing in magnesia pipe and the draw unit head 5 that is held in the cavity volume 8, and in order to guarantee that magnesia pipe is in reasonable plastic state, to carry out suitable heating to processed magnesia pipe, make it be in best extended state.Except entering at magnesia pipe in the cavity volume 8, outside the porch of this cavity volume preheats by Electrothermal ring 11, be in work piece cavity volume 8 and when processed at magnesia pipe, then can be by the deep fat that is heated to design temperature by oil inlet 9 inputs, deep fat is sprayed onto on the draw unit head 5 of cavity volume 8 peripheries by nozzle, give cavity volume 8 and interior magnesia pipe heating thereof, and the oil under drenching is again via oil export 10, the returning to external oil piping system, can be entered once more by oil inlet 9 again after heating, heating circulates.When adopting the heating of circulating hot oil, can also adopt electric heating tube 12 to provide heating for magnesia pipe.And in order to save energy consumption, the relevant structure division of whole and magnesia pipe heating adopts thermal insulation layer 13 to stop heat-energy losses.So, draw unit head 5 might spread out heat via main shaft 4, so that influence the operate as normal of entire equipment, thereby, the thermal insulation layer 13 outer parts that are exposed to by 6 pairs of main shafts 4 of cooling water inlet are carried out the sprinkling of cooling water with cooling, water under drenching is again via water out 7, and returning to external cooling water channel system can be entered once more by cooling water inlet 6 again.
Certainly, the heating of above-mentioned circulating hot oil and the mode of heating of electric heating tube adopt except in the present embodiment the time, also can distinguish separately and adopt.
And, with cavity volume 8 and wherein the temperature of magnesia pipe be controlled at best processing temperature, such as about 220 ℃, prior art has a lot of Detection ﹠ Controling means, does not repeat them here.
The most preferred embodiment of the above is intended to specify thinking of the present utility model: make processed magnesia pipe can remain on the processing temperature of setting from structure.The enforcement of the utility model is not limited to the disclosed mode of above most preferred embodiment, and is all based on above-mentioned mentality of designing, simply deduces and replace, and the concrete machine for shrinking that obtains all belongs to enforcement of the present utility model.
