Abstract
The invention discloses a forming mechanism of an elliptical pipe machine. The forming mechanism comprises a roller mounting frame connected with a rack of the elliptical pipe machine; at least one roller group is mounted on the roller mounting frame; the roller group comprises two rollers with the same structure; the two rollers are tangent; a circumferential annular groove is arranged on the surface of each roller; the radial section of the annular groove is semi-elliptical; the annular grooves of the two rollers correspond to each other in position; and the two corresponding annular grooves are combined to form an elliptical forming hole. The annular grooves on the surfaces of the two rollers form the elliptical forming hole, thus the structure is simple; and when a round pipe passes through the forming hole, the friction force of the round pipe against the wall of the forming hole drives each roller to rotate, thus the abrasion of the annular grooves is reduced, the service life of the forming mechanism is prolonged, and the forming quality is improved.
Description
(1) technical field:
The present invention relates to a kind of process equipment of elliptical tube, be specially the shaping mechanism in Elliptical tube machine.
(2) background technology:
Existing Elliptical tube machine, comprises connecting gear and shaping mechanism, connecting gear clamping U-shaped pipe, the straight sections of U-shaped pipe is sent into the ellipse setting hole in shaping mechanism, is extruded, make straight sections become oval pipe by the hole wall in the hole that formalizes to U-shaped pipe.Described shaping mechanism comprises left intubate elliptical modes, middle intubate elliptical modes and right intubate elliptical modes, joint face between left intubate elliptical modes and middle intubate elliptical modes is provided with deep-slotted chip breaker accordingly, two deep-slotted chip breakers form oval forming hole, another oval setting hole is arranged between the joint face of middle intubate elliptical modes and right intubate elliptical modes, between left inclining tube elliptical modes and middle intubate elliptical modes, elastic recovery device is respectively equipped with between middle intubate elliptical modes and right inclining tube elliptical modes, the two ends of described shaping mechanism arrange one piece of pushing block respectively, two pushing blocks are connected with clamp driver.This shaping mechanism has following shortcoming: 1. complex structure, and during work, round tube produces larger radial pressure to the perisporium of deep-slotted chip breaker, and need elastic recovery device to overcome radial pressure, can say, molding effect depends on the quality of elastic recovery device; 2. round tube also also produces very large axial friction to deep-slotted chip breaker, and this frictional force is not single produces very galling to oval pipe, also makes shaping mechanism easily damage; Simultaneously in order to overcome this frictional force, the power of connecting gear also needs to increase.
(3) summary of the invention:
In order to overcome the deficiencies in the prior art, the object of this invention is to provide that a kind of structure is simple, efficiency is high, the shaping mechanism of good forming effect, non-damageable Elliptical tube machine.
The present invention is realized by following technical scheme:
A kind of shaping mechanism of Elliptical tube machine, comprise the roller installing rack be connected with the frame of Elliptical tube machine, roller installing rack is provided with at least one roller set, roller set comprises the identical roller of two structures, two rollers are tangent, the surface of roller is provided with the ring groove of circumference, the radial cross-sectional shape of ring groove is half elliptic, the annular groove position of two rollers is corresponding, two corresponding annular grooves are combined to form oval forming hole, described roller installing rack comprises mounting base, mounting base is provided with some columns, column is horizontally installed with two parallel upper rotating shafts and lower rotary shaft, two rollers of described roller set are arranged on rotating shaft and lower rotary shaft respectively, described upper rotating shaft for the upper rotating shaft described in eccentric shaft be eccentric shaft, described column is provided with and stretches into for instrument and described upper rotating shaft to be regulated to the adjustment hole of guaranteeing that each oval forming hole shape is consistent.
The width of ring groove described above is the minor axis length of oval forming hole, and the degree of depth of ring groove is the major semiaxis length of oval forming hole.
Roller surface described above is symmetrically distributed with the ring groove described in two.
Relative to prior art, the present invention has following advantage: form oval forming hole by the annular groove of two roller surface, structure is simple; When round tube is by shaped hole, the frictional force of round tube to forming hole hole wall makes roller rotate, thus decreases the wearing and tearing of annular groove, extends the service life of shaping mechanism, also improves Forming Quality; Because friction reduces, the power needed for feeding portion also reduces, and accomplishes energy-efficient.Two roller vertical directions arrangement of roller set, what make bottom annular groove is stressed average.A roller is provided with two annular grooves, can extrude the two ends of U-shaped round tube simultaneously, and an Elliptical tube machine can be provided with several roller set, and can carry out processing and forming to many round tubes, efficiency improves further simultaneously.
(4) accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of a roller set on column.
(5) detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is described in detail:
As Fig. 1, shown in Fig. 2, the present invention is arranged in the frame of Elliptical tube machine, comprise the roller installing rack be connected with frame, roller installing rack comprises mounting base 211, mounting base 211 is provided with some columns 212, column 212 is horizontally installed with two parallel upper rotating shafts 213 and lower rotary shaft 214, upper rotating shaft 213 is provided with upper roller 221, lower rotary shaft 214 is provided with bottom roller 222, upper roller 221 is identical with bottom roller 222 structure, tangent mutually, the surface of upper roller 221 and bottom roller 222 is provided with the ring groove 223 of circumference, the radial cross-sectional shape of ring groove 223 is half elliptic, upper roller 211 is corresponding with ring groove 223 position of bottom roller 212, two corresponding annular grooves 223 are combined to form oval forming hole 23.
The width of ring groove 223 is the minor axis length of oval forming hole 23, and the degree of depth of ring groove 223 is the major semiaxis length of oval forming hole 23.
Annular groove 223, roller set that upper roller 221 described above and bottom roller 222 surface are symmetrically distributed with described in two can extrude the two ends of U-shaped round tube simultaneously.
The present invention forms oval forming hole 23 by the annular groove 223 of two roller surface, and structure is simple; When round tube is by oval forming hole 23, the frictional force of round tube to oval forming hole 23 hole wall makes upper roller 221 and bottom roller 222 rotate, thus decrease the wearing and tearing of U-shaped pipe to annular groove 223, extend the service life of shaping mechanism, also improve Forming Quality; Because friction reduces, the power needed for feeding portion also reduces, and accomplishes energy-efficient.Upper roller 211 and the arrangement of bottom roller 212 vertical direction, what make bottom annular groove is stressed average.Mounting base 211 can be provided with several roller set, and can carry out processing and forming to many round tubes, efficiency improves further simultaneously.
