Abstract
The utility model 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 utility model relates to a kind of process equipment of elliptical tube, is specially the shaping mechanism in the elliptical tube machine.
(2) background technology:
Existing elliptical tube machine comprises connecting gear and shaping mechanism, and connecting gear clamps the U-shaped pipe, and the straight sections of U-shaped pipe is sent into the ellipse setting hole in the shaping mechanism, and the hole wall through the setting hole pushes the U-shaped pipe, makes straight sections become oval pipe.Described shaping mechanism comprises left intubate elliptical modes, middle intubate elliptical modes and right intubate elliptical modes; Be provided with deep-slotted chip breaker accordingly on the joint face between left side intubate elliptical modes and the middle intubate elliptical modes; Two deep-slotted chip breakers are formed oval moulding hole; Another oval setting hole is arranged between the joint face of middle intubate elliptical modes and right intubate elliptical modes; Between a left side oblique cutting pipe elliptical modes and the middle intubate elliptical modes, be respectively equipped with elastic recovery device between middle intubate elliptical modes and the right oblique cutting pipe elliptical modes, the two ends of said shaping mechanism are provided with a pushing block respectively, and two pushing blocks are connected with clamp driver.This shaping mechanism has following shortcoming: 1. complex structure, and round tube produces bigger radial pressure to the perisporium of deep-slotted chip breaker during work, and the elasticity of demand recovery device overcomes radial pressure, we can say, and molding effect depends on the quality of elastic recovery device; 2. round tube also also produces very big axial friction to deep-slotted chip breaker, and this frictional force is not single to produce very galling to oval pipe, and shaping mechanism is damaged easily; In order to overcome this frictional force, the power of connecting gear also needs to increase simultaneously.
(3) summary of the invention:
In order to overcome the deficiency of prior art, the purpose of the utility model provide a kind of simple in structure, efficient is high, the shaping mechanism of good forming effect, non-damageable elliptical tube machine.
The utility model is to realize through following technical scheme: a kind of shaping mechanism of elliptical tube machine; Comprise the roller installing rack that is connected with the frame of elliptical tube machine; At least one roller set is installed on the roller installing rack, and roller set comprises two rollers that structure is identical, and two rollers are tangent; The surface of roller is provided with circumferential ring groove; The radial section of ring groove is shaped as half elliptic, and the annular groove position of two rollers is corresponding, and corresponding two annular grooves are combined to form oval moulding hole.
The width of above-mentioned said ring groove is the minor axis length in oval moulding hole, and the degree of depth of ring groove is the major semiaxis length in oval moulding hole.
Above-mentioned described roller surface is symmetrically distributed with two described ring grooves.
Above-mentioned described roller installing rack comprises the installation base plate, installs on the base plate some columns are installed, and is horizontally installed with two parallel last rotating shaft and lower rotary shafts on the column, and two rollers of said roller set are installed in respectively on rotating shaft and the lower rotary shaft.Described upward rotating shaft is an eccentric shaft.
With respect to prior art, the utility model has following advantage: the annular groove through two roller surface forms oval moulding hole, and is simple in structure; When round tube passed through shaped hole, round tube rotated roller to the frictional force of moulding hole hole wall, thereby has reduced the wearing and tearing of annular groove, has prolonged the service life of shaping mechanism, has also improved Forming Quality; Because friction reduces, the required power of feeding portion also reduces, and accomplishes energy-efficient.Two roller vertical directions of roller set are arranged, and make the stressed average of annular groove bottom.A roller is provided with two annular grooves, can push simultaneously the two ends of U-shaped round tube, can be provided with several roller set on the elliptical tube machine, can carry out processing and forming to many round tubes simultaneously, and efficient further improves.
(4) description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of a roller set on the column.
(5) specific embodiment:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Like Fig. 1, shown in Figure 2, the utility model is installed on the frame of elliptical tube machine, comprises the roller installing rack that is connected with frame; The roller installing rack comprises installs base plate 211; Install on the base plate 211 some columns 212 are installed, be horizontally installed with two parallel last rotating shaft 213 and lower rotary shafts 214 on the column 212, in the last rotating shaft 213 upper roller 221 is installed; Bottom roller 222 is installed on the lower rotary shaft 214; Upper roller 221 is identical with bottom roller 222 structures, tangent mutually, and the surface of upper roller 221 and bottom roller 222 is provided with circumferential ring groove 223, and the radial section of ring groove 223 is shaped as half elliptic; Ring groove 223 positions of upper roller 211 and bottom roller 212 are corresponding, and corresponding two annular grooves 223 are combined to form oval moulding hole 23.
The width of ring groove 223 is the minor axis length in oval moulding hole 23, and the degree of depth of ring groove 223 is the major semiaxis length in oval moulding hole 23.
Above-mentioned described upper roller 221 is symmetrically distributed with 223, one roller set of two described annular grooves with bottom roller 222 surfaces and can pushes simultaneously the two ends of U-shaped round tube.
The utility model forms oval moulding hole 23 through the annular groove 223 of two roller surface, and is simple in structure; When round tube during through oval moulding hole 23; Round tube rotates upper roller 221 and bottom roller 222 to the frictional force of oval moulding hole 23 hole walls; Thereby reduced of the wearing and tearing of U-shaped pipe, prolonged the service life of shaping mechanism, also improved Forming Quality annular groove 223; Because friction reduces, the required power of feeding portion also reduces, and accomplishes energy-efficient.Upper roller 211 is arranged with bottom roller 212 vertical directions, makes the stressed average of annular groove bottom.Install on the base plate 211 and can be provided with several roller set, can carry out processing and forming to many round tubes simultaneously, efficient further improves.
Described upward rotating shaft 213 is an eccentric shaft.Described column 212 is provided with adjustment hole 215, and staff's tool stretches in the adjustment hole 215 last rotating shaft 213 is regulated.Guarantee that each oval moulding hole 23 shape is consistent.
The foregoing description is the preferred embodiments of the utility model; But the embodiment of the utility model is not limited thereto; Other are any not to deviate from change, the modification done under spirit and the principle of the utility model, substitute, combination, simplify; Be the substitute mode of equivalence, be included within the protection domain of the utility model.
