Abstract
The invention relates to a steel pipe shaping machine, in particular to a pipe bender, which comprises a horizontally positioned fixed base. A rotating base is arranged on the fixed base in a horizontally rotating manner; a driving wheel for bending pipes is arranged on a rotating shaft of the rotating base in a concentrically fixed manner; a driven wheel for bending the pipes is arranged on the rotating base in a horizontally rotating manner; a bending crack is formed between the driving wheel for bending the pipes and the driven wheel for bending the pipes; a locking assembly consisting of a fixed locking block and a movable locking block is further arranged on the rotating base; and a locking crack is formed between the fixed locking block and the movable locking block. The bending curve of a steel pipe is limited by means of matching of the driving wheel for bending the pipes and the driven wheel for bending the pipes, the steel pipe is locked by means of matching of the fixed locking block and the movable locking block, and the steel pipe is rotatably pulled, so that the steel pipe is accurately and efficiently bent.
Description
Technical field
The present invention relates to a kind of steel pipe typing machinery, relate in particular to a kind of bending machine.
Background technology
Evaporation tube is crucial parts in the refrigerator, and especially in the absorption-diffusion type refrigeration system, evaporation tube is being brought into play crucial effects.Evaporation tube is former to be manual bending, and stepping up of pipe also is to tighten up a screw through manual work to accomplish, and such processing mode at first very effort and efficient is extremely low, and the precision of bending is not high, often do not reach the technical indicator of evaporation tube requirement.
Summary of the invention
The invention provides a kind of bending machine, its bending that can efficiently accomplish steel pipe accurately is to satisfy the specification requirement of evaporation tube.In order to realize the foregoing invention purpose, the present invention has adopted following technological means:
A kind of bending machine comprises horizontally disposed fixed pedestal; Horizontally rotate on the said fixed pedestal and be provided with rotating basis; Be set with the bend pipe driving wheel on the rotating shaft of said rotating basis with one heart; Horizontally rotate on the said pedestal and be provided with the bend pipe follower; Form the bending crack between said bend pipe driving wheel and the bend pipe follower; Also be provided with the locking assembly of forming by fixedly lock dog and movable lock dog on the said rotating basis, form the locking crack between said fixedly lock dog and the movable lock dog.
Said fixedly lock dog is fixedly installed on the rotating basis, and its clamping face and bend pipe driving wheel are tangent;
Said bend pipe follower can horizontal linearity move;
Said rotating basis is rotated by motor-driven.
Beneficial effect of the present invention is: the cooperation through bend pipe driving wheel and bend pipe follower limits the bending curve of steel pipe, through fixedly lock dog and movable lock dog lock steel pipe, rotation traction traction steel pipe, thereby the accurate bending of accomplishing steel pipe efficiently; Fixedly lock dog clamping face and bend pipe driving wheel are tangent, make that the traction bending of steel pipe is more suitable sliding; The bend pipe follower can horizontal linearity move, thereby the width that can adjust the bending crack bends with the steel pipe that adapts to different thicknesses.
Description of drawings
Fig. 1 is the structural representation of a kind of bending machine of the present invention;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred implementation of a kind of bending machine of the present invention is made detailed description:
As shown in Figure 1, this bending machine comprises the fixed pedestal 1 that fixing horizontal is provided with, and rotates on the fixed pedestal 1 and is provided with rotating basis 2, and rotating basis 2 can horizontally rotate on fixed pedestal 1.Be provided with motor below the fixed pedestal 1, in order to 2 rotations of driven in rotation pedestal.
Rotating basis 2 is provided with bend pipe driving wheel 3, fixedly lock dog 4 and movable lock dog 6.The concentric bend pipe driving wheel 3 that fixedly installs on the rotating shaft of rotating basis 2 offers the semicircular bending groove 13 of a circle on the wheel face of bend pipe driving wheel 3.
The right of bend pipe driving wheel 3 fixedly installs a fixedly lock dog 4, and fixedly the lower surface of lock dog 4 is that the cross section is semicircular locking slot 14, locking slot 14 be about towards straight-line groove, and tangent with the lower end of bend pipe driving wheel 3.
Fixedly the below of lock dog 4 fixedly installs movable lock dog shell 8; In the movable lock dog shell 8 movable lock dog 6 is set; Movable lock dog 6 can move up and down and lock in movable lock dog shell 8; The upper surface of movable lock dog 6 also be the locking slot 14 of cross section semicircular in shape, and being separated by with the fixing locking slot 14 of lock dog 4 constitutes a locking crack 12, and fixedly lock dog 4 and movable lock dog 6 and movable lock dog shell 8 etc. constitute steel pipe jointly and lock assembly.
Fixedly install a follower shell 7 on the fixed pedestal 1; It is positioned at the below of bend pipe driving wheel 3; Be provided with a motion bar in the follower shell 7, this motion bar can move up and down and lock in follower shell 7, rotates on the upper end of motion bar and is provided with two bend pipe followers 5; These two bend pipe followers about 5 are arranged, and the bend pipe follower 5 on the right and bend pipe driving wheel 3 are up and down point-blank.Also offer the semicircular bending groove 13 of a circle on the wheel face of bend pipe follower 5, being separated by with the bending groove 13 of bend pipe driving wheel 3 constitutes a bending crack 11.Bending crack 11 is positioned on the straight line with locking crack 12 jointly.
Fixed installation electric cabinet 9 in the lower left of fixed pedestal 1 is provided with switch 10 on the electric cabinet 9, in order to the motor switch under the control fixed pedestal 1 with 2 rotations of driven in rotation pedestal or stop.
In the time of the work of this bending machine, earlier bend pipe follower 5 and movable lock dog 6 are moved down, bending crack 11 and locking crack 12 are opened, steel pipe is put into bend pipe crack 11 and locking crack 12; Upwards promote bend pipe follower 5, make bending groove 13 with the steel pipe chucking, lock bend pipe follower 5 then, the promotion activity lock dog 6 that makes progress again, matching and fixing lock dog 4 make locking slot 14 with steel pipe locking, locking activity lock dog 6 then; Open switch 10; Motor-driven rotating basis 2 is rotated counterclockwise; The stiff end of locking assembly traction steel pipe is rotated counterclockwise, and the movable end of steel pipe is limited point-blank by two bend pipe followers 5 all the time, under the effect of bend pipe driving wheel 3; Steel pipe is bent out circular bending accurately, thus the efficient accurate bending of accomplishing steel pipe.
