Abstract
The utility model discloses a kind of composite (back-up) roll for rolling spiral grooved tube, including sheet roller knife, pad, roll mandrel and round nut.Sheet roller knife and pad are made hollow form and are sleeved on roll mandrel, are realized by key connecting circumferentially positioned, and axially position passes through the shaft shoulder and realized with the round nut on axle；Roller cutter shaft adjusts to spacing by spacer thickness size, forms the roller knife of different pitch；The shape of roller knife cutter head on chip can control the flute profile of heat exchanger tube；The blade unit that the width of whole roll is gradually increased using size forms, and ensures the gradual deformation of processing, prevents rupture and fold.The utility model is rational in infrastructure, easy for installation, and cost is low, and replaceability is good, has the versatility of height.
Description
Technical field
The utility model patent belongs to cutting-tool engineering field, and in particular to a kind of composite (back-up) roll for rolling spiral grooved tube.
Background technology
At present, integrated knife is usually used during the tubular object extruding such as spiral grooved tube, in actual use, integrated knife structure is answered
Miscellaneous, processing tool acquires a certain degree of difficulty, whole that roller knife can only be discarded if local damage occurs for cutter head, causes very big waste；Integrated knife needs
While meeting the performance requirement of roller knife and axle, the material requirements to integrated knife is very high；For the spiral grooved tube of different model, need to add
The different integrated knife of work, versatility are very poor.
Utility model content
The purpose of this utility model is a kind of composite (back-up) roll for rolling spiral grooved tube of design, solves conventional monolithic roll
Performance is bad, poor universality, the problem of being not easy to change after damage.
In order to solve the above problems, the technical solution of the utility model is：
A kind of composite (back-up) roll for rolling spiral grooved tube, including sheet roller knife and roll mandrel；The centre of the sheet roller knife
Hole is provided with, multi-disc sheet roller broach shell is provided with one or more pads, roll on roll mandrel between adjacent sheet roller knife
Axle both sides are respectively by the shaft shoulder and catch by the axial grip of sheet roller knife.
Preferably, in addition to woodruff key, woodruff key coordinate with the Woodruff key slots and keyways on sheet roller knife, realize that sheet roller knife is rolling
It is circumferentially positioned on roll shaft.
Preferably, axial spacing is adjusted by changing pad quantity between adjacent sheet roller knife, changes tubular pitch.
Preferably, catch is fixed on roll mandrel using round nut.
Preferably, the quantity of round nut is two, and pad is provided between two round nuts.
Preferably, the length of sheet roller knife is 95 ± 0.04cm
Preferably, sheet roller knife thickness all same, sheet roller knife top are fillet, the radius of fillet for 0.25 ±
0.02cm。
, can not also between adjacent sheet roller knife in the composite (back-up) roll as another embodiment of the present utility model
Pad is set.
Positive effect of the present utility model is：Realized by key connecting circumferentially positioned, axially position passes through the shaft shoulder
Realized with the round nut on axle；Roller cutter shaft on chip adjusts to spacing by spacer thickness size, forms the roller knife of different pitch；
The shape of roller knife cutter head on chip can control the flute profile of heat exchanger tube；The width of whole roll uses the set of blades that size gradually increases
Conjunction forms, and ensures the gradual deformation of processing, prevents rupture and fold.The composite (back-up) roll is rational in infrastructure, easy for installation, into
This is low, and replaceability is good, has the versatility of height.
Brief description of the drawings
By reference to the explanation below in conjunction with accompanying drawing, and with being more fully understood to of the present utility model, this practicality is new
The other purposes and result of type will be more apparent and should be readily appreciated that.In the accompanying drawings：
Fig. 1 is the structural representation of the utility model composite (back-up) roll；
Fig. 2 is another structural representation of the utility model composite (back-up) roll；
Fig. 3 is the structural representation of sheet roller knife；
Fig. 4 is the partial enlarged drawing of part A in Fig. 3.
Wherein：Roll mandrel 1, pad 2, sheet roller knife 3, round nut 4, the shaft shoulder 5, woodruff key 6, catch 7.
Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, complete description, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole realities
Example is applied, based on the embodiment in the utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figure 1-2, as shown in figure 1, opening circular hole, roller knife thickness all same in the middle part of sheet roller knife.Sheet roller knife-edge edge
Into certain taper, top is fillet, and the radius R of fillet is 0.25 ± 0.02cm.Sheet roller knife radius can with it is identical can not also
Identical, radius distance value is changing into hyperbola distribution.Composite (back-up) roll of the present utility model mainly includes sheet roller knife 3, roll mandrel
1st, pad 2 and round nut 4.Sheet roller knife 3 makes hollow structure, and multi-disc sheet roller knife 3 is sleeved on roll mandrel 1 together, leads to
The effect of the shaft shoulder 5, catch 7 and two round nuts 4 is crossed, realizes the axial grip of sheet roller knife 3, while realizes that sheet roller knife 3 exists
Axially position on roll mandrel 1；By the cooperation of the Woodruff key slots and keyways on woodruff key 6 and sheet roller knife 3, realize that sheet roller knife 3 exists
It is circumferentially positioned on roll mandrel 1；Some pads 2 can be increased between every sheet roller knife to change between two neighboring roller knife
Distance, realize the adjustment of pitch.
Above-described is only preferred embodiment of the present utility model, should be told, for the ordinary skill of this area
For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
