Description
Technical field
The present invention relates to a kind of vertical pipe expander.
Background technology
Electric tube expander is used to the numerous heat exchanger pipe fitting diameters be placed in fin to swell, and makes it to combine closely with fin, avoids producing loosening, and increases the heat conductivility of heat exchanger, carries out enlarging and flange in addition, be beneficial to carry out next procedure to pipe fitting end.
Existing vertical pipe expander comprises base, the frame be arranged on base, power seat, flare seat and move back die holder, expander roll is arranged on power seat, expander roll is through multiple gripper shoe and by gripper shoe fixed support, move back die holder generally to be driven by the screw body be arranged on support, the nut of screw body is directly fixed on and moves back on die holder, the movement of therefore moving back die holder relies on screw body completely, and translational speed is comparatively slow, and operating efficiency is lower.
Summary of the invention
Technical problem to be solved by this invention be overcome prior art above-mentioned defect and a kind of rapid die release mechanism of vertical pipe expansion machine is provided, movement can move back die holder fast.
The present invention solves the problems of the technologies described above adopted technical scheme:
Rapid die release mechanism of vertical pipe expansion machine; comprise and move back die holder, lower screw mandrel and nut, it is characterized in that: lower screw mandrel is erected at and moves back die holder both sides, and nut is installed in its upper end; move back mould cylinder in described installation on die holder two sides of moving back, the described piston rod moving back mould cylinder is connected with nut.
Above-mentioned mounting spring of moving back above die holder supports flare seat.
After frame, also arrange a cat ladder, be fixed on below described cat ladder on base, top is fixed in frame.
Compared with prior art, the invention has the advantages that:
1. by move back in template install move back mould cylinder, movement can move back die holder fast, increase work efficiency.
2. by installation cat ladder, operating maintenance is convenient on the one hand, also can strengthen the bending resistance of equipment simultaneously.
Accompanying drawing explanation
Fig. 1 is the stereogram that the embodiment of the present invention contains rapid die release mechanism of vertical pipe expansion machine.
Fig. 2 is the stereogram of embodiment of the present invention vertical pipe expander not with workbench.
Fig. 3 is that embodiment of the present invention vertical pipe expander is containing the partial perspective view moving back mold mechanism fast.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1, 2, 3, vertical pipe expander, comprises base 1, it installs portal frame 10, frame 10 2 leading flanks installs the line slideway 16 be parallel to each other separately, frame 10 2 medial surfaces install the inboard track 101 be parallel to each other separately.
Force transmission rack 8 is placed in frame 10, the roll wheel assembly frame installed by two sides is on frame inboard track 101, and can move up and down along frame inboard track 101, force transmission rack 8 lower end is connected with the nut of ball screw 3, ball screw 3 is arranged on the below base 1 in frame 10, and force transmission rack 8 upper side installs power seat 9.
Expander roll 14 is arranged on the expander roll locking device below power seat 9, and expander roll 14 is through multiple gripper shoe 7 and by multiple gripper shoe 7 fixed support.
The mold mechanism that moves back fast moving back die holder 4 is: lower screw mandrel 2 and drive unit 201 thereof are arranged on the base 1 that moves back below die holder 4; lower feed screw nut 17 is installed in lower screw mandrel 2 upper end; move back mould cylinder 18 and be fixed on the side moving back die holder, the piston rod and the lower feed screw nut 17 that move back mould cylinder 18 fix.
For making lower feed screw nut 17 stress equalization and better mobile, arrange guide rod 41 at the opposite side relatively moving back mould cylinder 18 piston rod of lower feed screw nut 17, guide rod 41 moves back on die holder 4 through the sidepiece being fixed on of lower feed screw nut 17, sees Fig. 3.
Above-mentioned to move back above die holder 4 also mounting spring support in flare seat 5(figure show draw).
As shown in Figure 1, 2, after frame, also arrange a cat ladder 20, be fixed on base 4 below described cat ladder 20, top is fixed in frame 1, makes operating maintenance become very convenient on the one hand, also enhances the bending resistance of equipment simultaneously.
During the work of the present embodiment rapid die release mechanism of vertical pipe expansion machine, first upper screw rod 6 is driven to rotate by the drive unit 601 of upper screw rod 6, thus changing the position of its upper screw rod nut 602 and the flare seat 5 fixing with upper screw rod nut 602, the position of upper screw rod nut 602 determines carries out the original position that pipe fitting expands cup-shaped recess and pipe end taper flange; By the drive unit 201 of lower screw mandrel 2, drive lower screw mandrel 2 to rotate, thus change the position of its lower feed screw nut 17, and then change the position of moving back die holder 4 and the position of moving back die holder 4 opposite piece 15 fixed with lower feed screw nut 17; By the position of ball screw 3 motivation of adjustment seat 9, the i.e. initial position of expander roll 14 opposite piece 15.
After adjustment, stacked rotary table install workpiece 15 and clamps, moving back mould cylinder 18 drive and move back die holder 4 to next segment distance workpiece pressing, just can start working.
Ball screw 3 drives force transmission rack 8, power seat 9, expander roll 14 to move downward beginning expand tube, encounter the upper screw rod nut 602 on upper screw rod 6 when power seat 9 after, drive flare seat 5 also to move downward just to start to expand cup-shaped recess and the action of pipe end taper flange, now expand tube action is still being carried out, Deng expansion cup-shaped recess and the release of pipe end taper flange, expand tube action also terminates simultaneously, power seat 9 drives expander roll 14 to return fast afterwards, move back mould cylinder 18 to drive and move back die holder 4 and to move up fast a segment distance, realize moving back mould fast.
Although what the present embodiment adopted is the electric tube expander of gate frame, moving back die holder is the required parts of this type of rapid die release mechanism of vertical pipe expansion machine, and therefore this moves back mold mechanism fast and is applicable to too in the rapid die release mechanism of vertical pipe expansion machine of other types.
