The pipe bender is characterized in that the pipe bender is further provided with a lead screw, a screw nut, a driving wheel and driven wheels, the lead screw is connected with the coupling, the screw nut is sleeved on the lead screw, the driving wheel is fixed on the screw nut, the lathe bed is equipped with slide grooves which have two and are symmetrically distributed on two sides of the lead screw, the driven wheelshave two, and sliding blocks are arranged on the driven wheels and mounted in the slide grooves. The pipe bender is reasonable in design, low in cost and convenient in operation and maintenance, and can be used for producing U-shaped stainless steel pipes of various types.

Description

Bending machine
Technical field
The utility model relates to a kind of bending machine, is mainly used in to make U type stainless steel tube.
Background technology
In the prior art, the bending machine structure that can make multiple model U type pipe is comparatively complicated, and maintenance and operation gets up very inconvenient, and price is also comparatively expensive simultaneously; Though and the bending machine of making single model U type pipe is simple in structure, low price, range of application is wideless, can only make a kind of U type pipe of model.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned shortcoming in the prior art, and a kind of reasonable in design, with low cost, the bending machine that can produce multiple model U type stainless steel tube are provided.
The technical scheme in the invention for solving the above technical problem is: a kind of bending machine, comprise motor, conveyer belt, decelerator, lathe bed and shaft coupling, motor is connected with conveyer belt, conveyer belt is connected with decelerator again, decelerator is connected with shaft coupling again, it is characterized in that: also be provided with screw mandrel, feed screw nut, driving wheel and follower; Described screw mandrel is connected with shaft coupling; Described feed screw nut is socketed on the screw mandrel; Described driving wheel is fixed on the feed screw nut; Described lathe bed is provided with chute, and chute is two, and it is symmetrically distributed in the screw mandrel both sides; Described follower is two, and it is provided with slide block, and slide block is installed in the described chute.
The wheel face of driving wheel described in the utility model and follower is provided with annular groove.
The center line of chute described in the utility model is perpendicular to the axis of described screw mandrel.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design; 2, with low cost, operation and maintenance convenience; 3, can produce the U type stainless steel tube of multiple model.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the wheel face schematic diagram of the utility model driving wheel and follower.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, the utility model comprises motor 1, conveyer belt 2, decelerator 3, shaft coupling 4, lathe bed 5, screw mandrel 6, feed screw nut 7, driving wheel 8 and follower 9.
Driving wheel 8 is provided with annular groove 11 with the wheel face of follower 9.
Motor 1 effect is as the power output source, because its rotating shaft can't be directly supporting with decelerator 3 power shafts, so be connected with conveyer belt 2 between motor 1 and decelerator 3, plays the effect of transferring power.Because the rotating shaft of motor 1 has than high rotational speed, and the rotating speed of screw mandrel 6 can not be too high in the utility model, so be provided with decelerator 3.
Be connected with shaft coupling 4 between decelerator 3 and the screw mandrel 6.Be connected with feed screw nut 7 on the screw mandrel 6, with bolting driving wheel 8 arranged on the feed screw nut 7.Because screw mandrel 6 is provided with helical thread, and also is provided with helical thread in the feed screw nut 7, so when screw mandrel 6 rotated, driving wheel 8 just can be along with feed screw nut 7 moves at the axis of screw mandrel 6 directions X.
Lathe bed 5 is provided with chute 10, and its quantity is two, is symmetrically distributed in screw mandrel 6 both sides, and its center line Y is perpendicular to the axis X of screw mandrel 6.Follower 9 quantity are two also, and it is provided with slide block, and slide block is installed in the chute 10, and available bolting.When needs are adjusted the position of follower 9, can turn on bolt, slide block can be moved in chute 10, after the position of follower 9 is adjusted, tight a bolt, make follower 9 fixing.
During use, the position of adjusting two followers 9 according to the U type stainless steel tube model that will produce, make it be symmetrically distributed in screw mandrel 6 both sides, then straight stainless steel tube A is placed between two followers 9 and the driving wheel 8, start motor 1, adjust screw mandrel 6 rotation directions, driving wheel 8 is moved to straight stainless steel tube direction, after driving wheel 8 touched straight stainless steel tube A, it continued to move forward.Because the thrust of driving wheel 8 is very big, along with the continuation of driving wheel 8 is moved, straight stainless steel tube A will be bent to U type stainless steel tube gradually.When the core wheel that moves to its core wheel and two followers 9 when driving wheel 8 was positioned at collinear position, straight stainless steel tube A was bent to qualified U type stainless steel tube just, at this moment can shut-down operation.
In addition, need to prove, allly conceive equivalence or the simple change that described structure, feature and principle are done, all should be included in the protection domain of the utility model patent according to the utility model patent.
