Technical field
A kind of Bundy tube former is the utility model is related to, specifically, relate to a kind of duplex bearing roll Bundy tube
Steady shaping mechanism.
Background technology
The shaping of Bundy tube is to push aside roller by the gradual roll off shaping of sheet material by one, and roll off is required to upper and lower two each time
Mutual cooperation between individual roll；Roll in traditional welded tube mill is driven using double roller, and topping roll passes through a universal joint shaft coupling
Device connects a power motor, and bottom roll connects a power motor also by a gimbal coupling, and when in use, bottom roll leads to
It is often fixed position, due to being driven by gimbal coupling, vibratory output is very big, while pipe fitting fill process is unstable, double
Under weight reason, cause the forming process of pipe fitting easily to offset, at this moment just need topping roll being designed as adjustable, can typically set
One of translot is counted, by adjusting position of the topping roll in translot, to balance the offset of pipe fitting.
On this basis, due to the structure problem of topping roll, the strength for causing the vibration of shaft coupling in running to push
Frame is passed to, the strength that frame vibration pushes passes to topping roll, causes the rotating shaft of whole topping roll to be in a kind of pressure-bearing shape
State, it is easy to damage, and then cause rolls damage, Bundy tube Forming Quality is poor, changes the frequent and higher system of grade one of replacement cost
Row problem.
In order to solve the problem present on, people are seeking a kind of preferable technical solution always.
The content of the invention
The purpose of this utility model is in view of the shortcomings of the prior art, so as to provide a kind of design science, simple in construction, raw
The production steady shaping mechanism of duplex bearing roll Bundy tube that cost is low, product quality is high.
To achieve these goals, technical scheme is used by the utility model：A kind of duplex bearing roll Bundy tube is put down
Steady shaping mechanism, including the first roll and second roll be arrangeding in parallel, the first roll outer peripheral face middle part are provided with arcuation
Projection, the corresponding arcuation projection in second roll outer peripheral face middle part are provided with arcuation groove, and the first roll is vertically
First through hole is offered, the second roll offers the second through hole, the both ends of the first roll and described second vertically
The both ends of roll offer bearing mounting hole respectively, are separately installed with bearing in each bearing mounting hole, in the bearing
Fixing axle is installed.
Based on above-mentioned, the internal diameter of the internal diameter of the first through hole and second through hole is respectively less than the bearing mounting hole
The internal diameter of internal diameter, the internal diameter of the first through hole and second through hole is all higher than the internal diameter of bearing, the first through hole both ends
Installation step is formed respectively with the second through hole both ends and the bearing mounting hole；The bearing is arranged on the installation step
On.
Based on above-mentioned, each bearing mounting hole outer end is provided with annular dust excluding plate, and the fixing axle is through described
It is arranged on after annular dust excluding plate on the bearing.
Based on above-mentioned, the annular dust excluding plate outer rim is provided with external screw thread, and the outer spiral shell is corresponded in the bearing mounting hole
Line is provided with internal thread.
The utility model has substantive distinguishing features and progress compared with the prior art, and specifically, the utility model is different from
Traditional Bundy tube molding roller, it realizes the first roll by the setting of the bearing mounting hole and the bearing
With freely rotating for the second roll, it is driven that traditional double roller type of drive is changed into double roller, drive mechanism is eliminated, carries
The high stability of roll rotation, and then improve product quality；It has design science, simple in construction, production cost is low, production
The advantages of quality is high.
Brief description of the drawings
Fig. 1 is the structural representation of the steady shaping mechanism of duplex bearing roll Bundy tube in the utility model.
In figure：1. first roll；2. second roll；3. arcuation is raised；4. arcuation groove；5. bearing mounting hole；6.
Bearing；7. fixing axle；8. first through hole；9. annular dust excluding plate；10. installation step；11. the second through hole.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in figure 1, a kind of steady shaping mechanism of duplex bearing roll Bundy tube, including the He of first roll 1 be arrangeding in parallel
Second roll 2, the outer peripheral face of first roll 1 middle part are provided with arcuation projection 3, arcuation projection 3 are corresponded in the middle part of the outer peripheral face of second roll 2
It is provided with arcuation groove 4；Sheet material roll off gap, arcuation projection 3 and arcuation groove 4 are formed between first roll 1 and second roll 2
Cooperate, so as to by sheet material roll off into corresponding arc.
In order that two rolls can be rotated freely, first roll 1 offers first through hole 8, the edge of second roll 2 vertically
The second through hole 11 axially is offered, the both sides of first roll 1 and the both sides of second roll 2 offer bearing mounting hole 5 respectively, often
Bearing 6 is separately installed with individual bearing mounting hole 5, fixing axle 7 is installed in bearing 6；Fixing axle 7 is set for being fixedly connected with tubulation
It is standby, two bearings 6 are respectively provided with the both sides of each roll, fixing axle 7 passes through through hole, and both sides are separately mounted on a bearing 6,
A roll is supported with two fixing axles 7, roll rotation is got up more steady fixed, more smooth；Meanwhile the He of first through hole 8
The setting of second through hole 11 simplifies the structure of roll, facilitates the processing to first roll 1 and second roll 2, reduces life
Produce cost；In use, by the motion of sheet material, two roll rotations can be driven, the setting of drive mechanism is eliminated, avoids and roll
The vibration of roller.
When specifically used, under the dropping of external equipment, the gap between first roll 1 and second roll 2 leads to sheet material
Cross, while sheet material is by roll off, sheet material drives first roll 1 and second roll 2 to rotate, and realizes the driven rotation side of double roller
Formula, complete the steady shaping of Bundy tube.
In order to facilitate the installation of bearing 6, the internal diameter of the internal diameter of first through hole 8 and the second through hole 11 is respectively less than bearing mounting hole
