DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "indirectly connected" . Also, when an element is referred to as "comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a structural view, a cross-sectional view, and a perspective view of an apparatus for manufacturing a tube for a pneumo-hydraulic piping according to an embodiment of the present invention. Referring to FIG. 1, the apparatus for manufacturing a tube for pneumatic and hydraulic pipes according to an aspect of the present invention includes: a rolling unit 110 for rotating and discharging a tube at a predetermined angular velocity; And a winding unit including a housing (121) rotating at a predetermined angular velocity, a winding roll (122) provided inside the housing, and a bending roll (123) provided adjacent to an outer surface of the winding roll. A pipe manufacturing apparatus for a hydraulic and pneumatic piping is provided.

The rolled portion 110 may include a plurality of rolls that rotate in mutually opposite directions, and the plurality of rolls may be spaced apart from each other by a predetermined distance according to a required diameter at the time of rolling. The metal tube may be reduced in diameter while passing between a plurality of rolls provided in the rolling unit 110. At this time, the rolling unit 110 may rotate the metal tube around the shaft (not shown) to uniformly reduce the diameter of the metal tube. x) at a predetermined angular velocity around the center of rotation.

The winding unit includes a housing 121 that continuously rotates at a predetermined angular velocity, a winding roll 122 provided inside the housing, and a bending roll 123 provided adjacent to an outer surface of the winding roll, The metal tube discharged from the rolling unit 110 may be wound along an outer surface or an inner surface of the winding roll 122.

In particular, the metal tube may be bent along the inner surface of the winding roll 122, since the metal tube may be bent at a required curvature by the bending roll 123 before being wound. In this case, It may be in the form of an empty cylinder.

Conventionally, in order to utilize the space, a winding device is installed at the end of a wire manufacturing apparatus such as a wire, a pipe, a tube, or the like. However, this is designed to rotate only the winding roll along the discharge direction of the wire, There is a problem in that unnecessary load is applied to the wire rod during winding to lower the physical properties.

When the metal tube, which is discontinuously rotated and discharged from the rolling part 110, is wound on the winding roll 122, the housing 121 is rotated around the axis y in a direction parallel to the rotating direction of the metal tube So that the load applied to the metal tube can be reduced and canceled.

The housing 121 may be electrically and mechanically connected to the first driving unit 130 or a combination thereof and may be connected to the first driving unit 130 by a rotary power supplied from the first driving unit 130 to be equal to an average value of the discontinuous angular velocity of the tube. It can rotate continuously at an average angular velocity. That is, the tube and the housing 121 are rotated at the same average angular velocity as the parallel direction, and the respective planes including the axes x and y, which are the respective rotation axes, are mutually parallel, or the axes x and y are on the same plane Therefore, it is possible to prevent the tube, which is wound around the winding roll 122, from being warped or damaged.

Further, the bending roll 123 may be provided adjacent to the outer surface of the winding roll 122, and may include a pressing roll and at least one guide roll. The tube discharged from the rolling unit 110 can move to the outer surface or the inner surface of the winding roll 122 while passing between at least one guide roll and a pressing roll provided at the rear end of the guide roll presses the tube It can bend with a certain curvature. The pressing roll and the at least one guide roll may be rotationally powered from separate drive means, e.g., a motor, electrically, mechanically, or a combination thereof.

The metal tube discharged from the rolling unit 110 maintains a linear shape due to the hardness characteristics, so that it is difficult to wind the metal tube on the winding roll 122. The bending roll 123 bends the bending roll 123 uniformly in accordance with the curvature of the take-up roll 122 before the tube is wound to improve the adhesion to the outer surface or inner surface of the take-up roll 122 and the collection efficiency of the tube .

On the other hand, the winding unit may further include a tubular guide (not shown) that moves from one end to the other end of the winding roll 122 along the outer surface or the inner surface of the winding roll 122.

The tubular guide has a function of preventing the metal tube wound around the winding roll 122 from being sagged during the rotation of the housing 121 and fixing the metal tube.

Specifically, before the metal tube is wound, the tubular guide may be located at one end of the outer surface or inner surface of the take-up roll 122, and may be connected to the other end by an elastic member such as a spring. In this case, as the width or width of the wound metal tube increases, the tubular guide can passively move toward the other end, and the metal tube wound by the restoring force of the elastic member can be moved toward the other end of the winding roll 122 It can be pressed and fixed in the distal direction.

Also, before the metal tube is wound, the tubular guide may be located at one end of the outer surface or the inner surface of the winding roll 122, and may be connected to a separate hydraulic device or motor. In this case, as the width or width of the wound metal tube increases, the tubular guide can be automatically moved toward the other end by the hydraulic device or the motor, and the wound metal tube can be moved toward the other end of the winding roll 122 It can be pressed and fixed in the distal direction.

The passive or automatic movement of the tubular guide by the elastic member, the hydraulic device or the motor, and the fixing effect of the metal tube by the elastic member and the hydraulic device or the motor can be realized independently of each other.

2 is a block diagram of an apparatus for manufacturing a tube for pneumatic and hydraulic pipes according to another embodiment of the present invention. Referring to FIG. 2, the apparatus for manufacturing a tube for a pneumo-hydraulic pipe may further include a first synchronization unit 140 for synchronizing an average value of a discontinuous angular velocity of the tube with a continuous angular velocity of the housing 121. Specifically, the rolling unit 110 and the first driving unit 130 may be electrically connected through the first synchronizing unit 140.

The first synchronization unit 140 may be an electronic control unit such as a sensor or a controller and may synchronize the average rotation speed of the rolling unit 110 and the first driving unit 130, The initial angular velocity of the tube and the initial angular velocity of the housing 121 can be synchronized regardless of the operation time.

For example, when the angular speeds of the rolling unit 110 and the first driving unit 130 are set to 45 ° / sec at the start of the facility operation, a difference may occur between the two as the operating time increases, The load on the tube during tube winding can also be accumulated.

The sensor of the first synchronization unit 140 receives an electrical signal related to the angular velocity of the first driving unit 130 at a predetermined time interval or in real time and transmits the received electrical signal to the rolling unit 110, And the average angular velocity of the tube 121 and the tube 121 can be synchronized.

The sensor of the first synchronization unit 140 receives an electrical signal related to the average angular velocity of the rolling unit 110 at a predetermined time interval or in real time and the controller transmits the received electrical signal to the first driving unit 130, So that the average angular velocity of the tube 121 and the tube can be synchronized.

In addition, this synchronization method may be implemented in parallel by the first synchronization unit 140. That is, an initial value related to the angular velocity of the rolling unit 110 and the first driving unit 130 is set in the first synchronizing unit 140, and the electric signal about the angular velocity set by the controller is input at a predetermined time interval or in real time To the rolling unit 110 and the first driving unit 130, respectively, to synchronize the average angular velocity.

3 is a block diagram of an apparatus for manufacturing a tube for a hydraulic and pneumatic piping according to another embodiment of the present invention. 3, the pneumo-hydraulic pipe manufacturing apparatus may further include a second driving unit 150 for continuously rotating the winding roll 122 at a predetermined angular velocity. The continuous rotation speed of the winding roll 122, that is, the angular velocity can be synchronized with the average discharge speed of the tube discharged discontinuously from the rolling part 110. [

The winding roll 122 rotates about the axis z and can be manually rotated by an external force such as bending, contact, friction or the like of the discharged tube, and can be rotated with the second driving part 150 electrically, Or a combination thereof, and may be rotated at an average angular velocity that is equal to the discharge velocity of the tube by receiving the rotational power from the rotational power.

The rotation axis z of the winding roll 122 and the rotation axis y of the housing are perpendicular to each other and the rotation axis z of the winding roll 122 and the rotation axis x of the tube are mutually perpendicular The winding roll 122 can rotate in a direction parallel to the linear discharge direction of the tube and the rotational speed of the winding roll 122 can be synchronized with the average linear discharge speed of the tube. For example, when the average linear ejection speed of the tube is 0.5 m / sec and the diameter of the winding roll 122 is 1.0 m, the angular velocity of the winding roll 122 may be about 57.3 ° / sec.

Referring again to FIG. 3, the pneumo-hydraulic pipe manufacturing apparatus may further include a second synchronization unit 160 for synchronizing the average discharge speed of the tube with the angular velocity of the winding roll 122. In detail, the rolled portion 110 and the second driving portion 150 may be electrically connected through the second synchronizing portion 160.

The second synchronization unit 160 may be an electronic control unit such as a sensor or a controller and synchronously synchronizes the average tube discharge speed of the rolling unit 110 and the rotation speed of the second driving unit 150, The initial discharge speed of the tube and the initial angular speed of the winding roll 122 can be synchronized regardless of the operation time of the equipment.

For example, when the discharge speed of the rolling unit 110 and the angular speed of the second driving unit 150 are set to 0.5 m / sec and 57.3 deg / sec, respectively, at the start of facility operation, the operation time increases and the difference If these differences are accumulated, the tube discharge amount per unit time and the winding amount may be different, and the collection efficiency may be lowered.

The sensor of the second synchronization unit 160 receives an electrical signal related to the angular velocity of the second driving unit 150 at a predetermined time interval or in real time and transmits the received electrical signal to the rolling unit 110, To synchronize the average linear ejection speed of the tube with the angular velocity of the take-up roll 122.

On the contrary, the sensor of the second synchronizing unit 160 receives an electrical signal related to the average linear ejection speed of the rolling unit 110 at a predetermined time interval or in real time, and the controller outputs the received electrical signal to the second driving unit 150 to synchronize the angular velocity of the winding roll 122 with the average linear ejection velocity of the tube.

In addition, this synchronization method may be implemented in parallel by the second synchronization unit 160. That is, the second synchronizing unit 160 sets an initial discharge speed of the rolling unit 110 and an initial value of the angular velocity of the second driving unit 150, and the controller sets an initial value And may transmit them to the rolling unit 110 and the second driving unit 150 at a predetermined time interval or in real time to synchronize the angular velocity with the average discharge velocity.

Referring to FIG. 4, the apparatus for manufacturing a tube for a hydraulic and pneumatic pipe may further include a bearing part 170 provided at the front end and the end of the winding part. The bearing portion 170 can stabilize the rotational motion of the housing 121 by fixing the rotation axis y of the housing 121 and prevent the rotation of the winding roll 122 provided inside the housing 121. [ And the rotational behavior of the bending roll 123 can be further stabilized.

Meanwhile, the rotation drive of each of the above-described equipments can be performed by circulating the metal tube from the time when the metal tube starts to be wound along the inner surface or the outer surface of the winding roll to the time when the metal tube is wound around the entire surface and collect it , The rotation of the one cycle is stopped and the wound metal tube can be collected. After the collection, the rotation driving in the same manner as before can be resumed. The discharge speed of the metal tube and the rotation speed of each equipment may be set to the same value as that of the immediately preceding circulation and may be set differently as required.
