Abstract
The utility model relates to a bowl device, whose bolt diameter and lift angle can be adjusted. The utility model comprises a group of rolled thread wheels, each of which is provided with a thread teeth equably, each rolled thread wheel is arranged in a hole of the cover board of the engine base via an axletree, each axletree of the rolled wheel is distributed in the same angular of the cover board of the engine base equably, the hole for installing the axletree on the cover board of the engine base is oblate waist drum-shaped, the cover board is further provided with an adjusting screw which is connected with the thread of the axletree. The radial location of the axletree in the housing can be adjusted and the axis angle between the adjusting axletree and the working bolt can be adjusted to level with the lift angle of the thread via the adjusting screw. Adopting the adjusting device of the screw, the annular thread teeth of the rolled thread wheel can be adjusted to parallel with the thread teeth of the steel bar that is needed handling, thereby avoiding the intervention phenomenon. The utility model improves the accuracy of the thread handing, and further reduces the axial force of the rolled thread teeth, thereby prolonging the service life of the rolled thread teeth.
Description
Technical field
The utility model relates to a kind of metal-working plant, relates in particular to a kind of roll device of processing screw rod.
Background technology
Add man-hour carrying out the screw rod rolled thread, generally realize the adjustment of footpath size in the screw rod by turning round radial position that off-centre or cam mechanism change cylindrical die roll, its structure is complicated.During with annular cylindrical die roll rolling high precision screw rod, must make cylindrical die roll axial line and screw axis that the angle of cut is arranged and equate with the screw rod lift angle.Therefore, the manufacture process requirement to roll milling apparatus is very high.And the connecting screw rod not high to required precision, for example screw thread steel connects, and adopts the annular cylindrical die roll simple device parallel with screw axis to carry out rolled thread processing.But the cylindrical die roll thread and the screw rod thread of this structure exist interference, and the screw flight lift angle is big more, and interference degrees is just severe more.The thread profile of tooth, fineness and the pitch error that roll into like this are bigger, and because interference makes cylindrical die roll bear very big axial force, causing the destruction of cylindrical die roll annular thread nearly all is that thread axially fractures, and shorten service life greatly.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, adjust reliable, long service life, easily manufactured, screw diameter and the adjustable roll device of lift angle that can adjust synchronously at the variation of its diameter and lift angle the different size screw rod.
The utility model mainly comprises one group of cylindrical die roll, be evenly distributed with the screw thread teeth on each cylindrical die roll, each cylindrical die roll places in the hole of support cover plate by wheel shaft, each cylindrical die roll wheel shaft is evenly distributed on the same circumference of support cover plate, bearing is equipped with at the two ends of wheel shaft, its major technique is characterised in that: wheel shaft is installed in Kong Weibian waist fermented soya beans, salted or other wise shape hole on the support cover plate, on the cover board also is provided with adjustment screw, this screw is threaded with wheel shaft.By adjustment screw, can adjust the radial position of wheel shaft in foundation mass, and adjust wheel shaft and make it to equate with its lead angle with the axis angle of cut between the workpiece screw rod.Cylindrical die roll is located at the middle part of wheel shaft, and the cylindrical die roll two ends are with spheric washer respectively and adjust packing ring.Cylindrical die roll is made of cone and cylinder two parts.
Because the utility model has adopted the screw governor motion, can adjust cylindrical die roll annular thread and parallel, thereby avoid interference, not only improve the precision of screw thread processing with the screw rod tooth that it need be processed, also significantly reduce the axial force of cylindrical die roll thread, prolonged the service life of cylindrical die roll.Facts have proved that the utility model is used for rolling reinforcing bar thread head, can be enhanced about more than once the service life of cylindrical die roll.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the B of Fig. 1 is to view;
Fig. 3 is that the C-C of Fig. 2 is to the sectional structure schematic diagram.
The specific embodiment
The utility model includes one group of cylindrical die roll 2, and cylindrical die roll is located at the middle part of wheel shaft 3, and the quantity that has the wheel shaft 3 of cylindrical die roll is 2 to 4.Shown in the accompanying drawing is three wheel shafts, and the cylindrical die roll 2 on every wheel shaft is made up of cone 21 and cylinder 22 two parts.Be evenly equipped with the ring screw teeth on the cylindrical die roll 2, pitch is T, and the cross sectional shape of teeth can be a triangle, any in the trapezoidal or circular arc.Screw thread teeth on the cylindrical die roll are used for the machining screw workpiece as cutter.Wheel shaft 3 two ends are flat waist fermented soya beans, salted or other wise shape, match with the flat waist fermented soya beans, salted or other wise shape hole on being distributed on 1 liang of side cover plate of support, 6,7 circumference.The flat waist fermented soya beans, salted or other wise shape hole of the flat waist drum two ends of wheel shaft 3 and cover plate 6,7 is being slidingly matched of minim gap in the parallel surface direction, in the arc surface direction enough big space is arranged, to satisfy the coupling adjustment of straight warp of multiple screw rod and lift angle.On cover plate 6,7, also be respectively equipped with adjustment screw 9,10.Adjustment screw 9,10 is threaded with the two ends of wheel shaft 3 respectively.Turn adjustment screw 9,10 respectively, not only can adjust wheel shaft 3 radial position in engine housing 1, make it to equate with the axis angle of cut between the workpiece screw rod 8 with its lead angle λ but also can adjust wheel shaft 3.Position when the position when the solid line cylindrical die roll among Fig. 2 is processing minimum diameter workpiece, chain-dotted line cylindrical die roll are processing maximum gauge workpiece.The both sides of cylindrical die roll 2 are with spheric washer 41,42 respectively and adjust packing ring 5.Adjust packing ring 5 and can guarantee the pitch difference of the axial location of each cylindrical die roll to T/2 or T/3 or T/4.The two ends of support 1 cover with cover plate 6,7 respectively, are equipped with central through hole that screw rod 8 to be processed can pass and the flat waist fermented soya beans, salted or other wise shape hole that wheel shaft 3 is installed on the cover plate 6,7.
The utility model is placed on the special-purpose milling train, clamp the processing screw rod and it is passed the central through hole of roll, start milling train, make cylindrical die roll 2 do dextrorotation to rotating relative to screw rod 8, and axial feed, be rolling dextrorotation straight thread, after this make the roll counter-rotating, then cylindrical die roll withdraws from the screw rod 8 that is meshed with it automatically.Adjust the order of the alternate position spike (T/n) of cylindrical die roll 2 on wheel shaft 3, just can roll out left hand thread.Adjust and control cylindrical die roll 2 and the length that moves axially of processing screw rod 8, then rolling goes out pull bar, anchor pole, steel bar joint screw or high strength cold-rolled screw mandrel, cold-rolled threaded reinforcing steel etc. respectively.
