Among the figure: 1. base; 2. column; 3. positioning key; 4. lifting handwheel; 5. elevating screw; 6. bearing pin; 7. internal supporting block; 8. orienting sleeve.
Embodiment
Below in conjunction with the drawings and specific embodiments the adjustable interior support arrangement for heat treatment deformation control of the present invention is further described.
As depicted in figs. 1 and 2, a kind of adjustable interior support arrangement for heat treatment deformation control of the present invention mainly comprises base column 2, positioning key 3, lifting handwheel 4, elevating screw 5, bearing pin 6 and internal supporting block 7, orienting sleeve 8.
Wherein, the lower end of column 2 is fixed on base 1 top, and is fixedly connected by lower end and the base 1 of bolt with column 2, is made of the pedestal of whole interior support arrangement column 2 and base 1.Can fit with the bottom surface of the near closed hollow ring of workpiece in the bottom surface of base 1.
The upper end of column 2 is welded with orienting sleeve, positioning key 3 is fixed on the orienting sleeve 8 of column 2 upper ends, and lifting handwheel 4 is enclosed within orienting sleeve 8 inner and upper, and lifting handwheel 4 is threaded connection with elevating screw 5, by rotating lifting handwheel 4, drive elevating screw 5 and realize rising and descending.Orienting sleeve 8 is used for fixing positioning key 3 and lifting handwheel 4.Positioning key 3 be used for guaranteeing elevating screw 5 rise and the decline process in, keep translational motion and do not twist.
Internal supporting block 7 is arranged on elevating screw 5 tops, by bearing pin 6 internal supporting block 7 is connected with elevating screw 5.Internal supporting block 7 can be around the axis of bearing pin 6, in ± 10 ° of scopes, freely rotate, guarantee that internal supporting block 7 is when contacting with end face on the circular arc of the near closed hollow ring of workpiece, can pass through its rotation around bearing pin 6 axis, reach the purpose of the automatic alignment heart, the end face of internal supporting block 7 can be fitted with the upper end face of near closed hollow ring.
The height adjustment range L of above-mentioned interior support arrangement is relevant with effective adjustment length L 2 of column 2 effective working length L1 and elevating screw 5, height adjustment range L for support arrangement in improving as far as possible, make L1=L2 during design, interior like this support arrangement just can obtain the large height adjustment range of trying one's best in limited height design space.
During the stretching state, base 1 bottom surface contacts with profile under the near closed hollow ring, and profile match on internal supporting block 7 end faces and the near closed hollow ring circular arc reaches the internally purpose of stretching workpiece.Drive elevating screw 5 by lifting handwheel 4 and come the adjustment mechanism height.Adopt bearing pin 6 to connect elevating screw 5 and internal supporting block 7, internal supporting block 7 can freely rotate in the certain angle scope, realizes the function of the automatic alignment heart.
The use procedure of above-mentioned interior support arrangement is: (a) rotate lifting handwheel 4, interior support arrangement is foreshortened to the height of the near closed hollow ring of packing into; (b) interior support arrangement is positioned over die cavity bottom surface specified location, rotates lifting handwheel 4, drive elevating screw 5 and adjust height; (c) treat highly to rise to that end face rigidly connects when touching on internal supporting block 7 and the near closed hollow ring, continue the height that raises, until end face is fitted complete on internal supporting block 7 end faces and the near closed hollow ring circular arc.
