Description
Technical field
The utility model relates to a kind of vertical pipe expander.
Background technology
Electric tube expander is to be used for making it to combine closely with fin with placing the numerous heat exchanger pipe fitting diameters in the fin to swell, and avoids producing and becomes flexible, and increases the heat conductivility of heat exchanger, in addition pipe fitting end is carried out enlarging and flange, is beneficial to carry out next procedure.
Existing vertical pipe expander comprises base, is installed in frame, power seat, the enlarging seat on the base and moves back die holder; Expander roll is installed on the power seat, and expander roll passes a plurality of gripper shoes and by the gripper shoe fixed support, moves back die holder and generally driven by the screw body that is installed on the support; The nut of screw body directly is fixed on and moves back on the die holder; Therefore move back moving of die holder and rely on screw body fully, translational speed is slower, and operating efficiency is lower.
The utility model content
The utility model technical problem to be solved is to overcome the above-mentioned defective of prior art and a kind of vertical pipe expander that moves back mould fast is provided, and makes it fast moving move back die holder.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Move back the vertical pipe expander of mould fast; Comprise base, be installed in frame, power seat, the enlarging seat on the base and move back die holder, expander roll is installed on the power seat, and expander roll passes a plurality of gripper shoes and by the gripper shoe fixed support; It is characterized in that: following screw mandrel is erected at and moves back the die holder both sides; Nut is installed in its upper end, described move back to install on the die holder two sides move back the mould cylinder, the described piston rod that moves back the mould cylinder is connected with nut.
The above-mentioned die holder top mounting spring of moving back supports the enlarging seat.
Also in pedestal a cat ladder is set, described cat ladder below is fixed on the base, and upper fixed is on frame.
Compared with prior art, the advantage of the utility model is:
1. through moving back the mould cylinder moving back on the template to install, but fast moving is moved back die holder, increases work efficiency.
2. through a cat ladder is installed, operating maintenance is convenient on the one hand, but the also counter-bending ability of enhancement apparatus simultaneously.
Description of drawings
Fig. 1 moves back the stereogram of the vertical pipe expander of mould fast for the utility model embodiment.
Fig. 2 for the utility model embodiment vertical pipe expander not with the stereogram of workbench.
Fig. 3 for the utility model embodiment vertical pipe expander not with the part stereogram of workbench other direction.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Like Fig. 1,2, shown in 3; Move back the vertical pipe expander of mould fast, comprise base 1, portal frame 10 is installed on it; The line slideway 16 that is parallel to each other is installed on 10 2 leading flanks of frame separately, the interior side rails 101 that is parallel to each other is installed on 10 2 medial surfaces of frame separately.
Expander roll 14 is installed on the expander roll locking device 21 of power seat 9 belows, and expander roll 14 passes a plurality of gripper shoes 7 and by a plurality of gripper shoe 7 fixed supports.
Following screw mandrel 2 and drive unit 201 thereof are installed on the base 1 that moves back die holder 4 belows, and feed screw nut 17 is down installed in following screw mandrel 2 upper ends, moves back mould cylinder 18 and is fixed on the side that moves back die holder, move back the piston rod 181 of mould cylinder 18 and fix with following feed screw nut 17.
For making down feed screw nut's 17 stress equalizations and better moving, at the opposite side that moves back mould cylinder 18 piston rods 181 relatively that descends feed screw nut 17 guide rod 41 is set, guide rod 41 passes down feed screw nut 17 sidepiece and is fixed on and moves back on the die holder 4, sees Fig. 3.
Above-mentioned move back die holder 4 tops also mounting spring support 5 (show among the figure and draw) of enlarging seat.
Like Fig. 1, shown in 2, also a cat ladder 20 is set in pedestal, described cat ladder 20 belows are fixed on the base 4, and upper fixed makes operating maintenance become easily on frame 1 on the one hand, has also strengthened the counter-bending ability of equipment simultaneously.
When present embodiment moves back the vertical pipe expander work of mould fast; Drive unit 601 through upper screw rod 6 drives upper screw rod 6 rotations earlier; Thereby change its top nut 602 and with the position of the fixing enlarging seat 5 of top nut 602, the determining positions of nut 602 carry out the original position that pipe fitting expands cup-shaped recess and pipe end taper flange; Through the following drive unit 201 of screw mandrel 2, drive screw mandrel 2 rotations down, thereby change the position of its top nut 17, and then the position of moving back die holder 4 fixed of change and top nut 17 and the position of moving back die holder 4 relative workpiece 15; Through the position of ball screw 3 adjustment power seats 9, the i.e. initial position of expander roll 14 relative workpiece 15.
After adjusting finishes, on stacked rotary table, install workpiece 15 and clamping, move back 18 drives of mould cylinder and move back die holder 4, just can start working to next segment distance workpiece pressing.
Ball screw 3 drive force transmission racks 8, power seat 9, expander roll 14 move downward the beginning expand tube; After power seat 9 was run into the nut 602 on the upper screw rod 6, drive enlarging seat 5 also moved downward and just begins to expand cup-shaped recess and the action of pipe end taper flange, and this moment, the expand tube action was still carried out; Deng expansion cup-shaped recess and the release of pipe end taper flange; Expand tube action also finishes simultaneously, and power seat 9 drives expander rolls 14 and returns fast afterwards, moves back mould cylinder 18 and drives and move back die holder 4 segment distance that moves upward again.
Though what present embodiment adopted is an electric tube expander of type frame, moving back die holder is these type of essential parts of vertical pipe expander that move back mould fast, therefore originally moves back mold mechanism fast and is applicable to too in the vertical pipe expander that moves back mould fast of other types.
