The utility model content
Technical problem to be solved in the utility model is: provide a kind of boiler components to produce swan neck system with bending machine, this swan neck system stressed evenly against mould is difficult for deforming long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of boiler components is produced the swan neck system with bending machine, comprises frame; Rotation is installed on the main shaft on the frame; The bending pipe arm that is fixedly connected with main shaft; Be fixed in main shaft upper end and be positioned at the bending die of bending pipe arm top, this bending die is provided with for the die cavity that tubing is installed; Be installed on being used on the frame lean tubing in the bending die die cavity against mould, should be driven by power set against mould and lean or separate; Should comprise the mount pad that is slidingly mounted on the frame against mould, this mount pad drives with described power set and is connected; Die holder, this die holder is installed on the mount pad by connecting axle; Along the steel pipe throughput direction be slidingly installed on this die holder against mould body; Be used for the auxiliary fixedly fixture of die holder, this fixture is connected between die holder and the mount pad.
As a kind of preferred scheme, described fixture comprises first bearing in the downstream that is arranged on the mount pad; With the push rod that the first bearing is threaded, this push rod is in the downstream of tubing feeding with respect to connecting axle, and the end of described this push rod leans described die holder.
As a kind of preferred scheme, described fixture also comprises the pull bar that is fixedly connected on the die holder; Be fixedly installed in the second bearing of the upstream side on the mount pad, the second bearing is provided with installing hole, pull bar penetrating mounting holes and pass through fastening nuts.
After having adopted technique scheme, effect of the present utility model is: owing to be provided with the auxiliary fixedly fixture of die holder against mould, therefore, the phenomenon against the power inequality that in the time of can balanced tubing bend pipe die holder be caused, make it stressed evenly, avoid distortion, thereby improved the crooked precision of tubing, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment;
In the accompanying drawing: 1. frame; 2. main shaft; 3. bending die; 4. bending pipe arm; 5. against mould; 51. die holder; 52. against mould body; 53. connecting axle; 6. mount pad; 7. the first bearing; 8. push rod; 9. the second bearing; 10. pull bar; 11. upstream side; 12. downstream.
The specific embodiment
Below by specific embodiment the utility model is described in further detail.
The upstream side 11 of mentioning in the utility model and downstream 12 are orientation determinations of vertically carrying with tubing.The tubing first position of process is upstream side 11, after through be downstream 12.
As shown in Figure 1, a kind of boiler components is produced the swan neck system with bending machine, comprises frame 1; Rotation is installed on the main shaft 2 on the frame 1; This main shaft 2 is driven repeatedly by main shaft 2 drive units and rotates, its main shaft 2 drive units comprise that one drives cylinder, the driving chain that connects a sealing on the main shaft 2 of driving cylinder, link of this chain and main shaft 2 are fixing, thereby finish the repeatedly rotation of main shaft 2, the bending pipe arm 4 that is fixedly connected with main shaft 2 is during bend pipe, main shaft 2 drives bending pipe arms 4 and rotates, and is positioned at pressure die on the bend pipe wall and then compresses the tubing pipe die 3 of going for a stroll and rotate an angle; Be fixed in main shaft 2 upper ends and be positioned at the bending die 3 of bending pipe arm 4 tops, this bending die 3 is provided with for the die cavity that tubing is installed; Be installed on being used on the frame 1 lean tubing in bending die 3 die cavitys against mould 5, should be driven by power set against mould 5 and lean or separate, the same cylinder of all selecting of the power set of these power set and pressure die drives quadric chain; Should comprise the mount pad 6 that is slidingly mounted on the frame 1 against mould 5, this mount pad 6 drives with described power set and is connected; Die holder 51, this die holder 51 is installed on the mount pad 6 by connecting axle 53; Along the steel pipe throughput direction be slidingly installed on this die holder 51 against mould body 52; Be used for the auxiliary fixedly fixture of die holder 51, this fixture is connected between die holder and the mount pad 6.
