Problems solved by technology

[0005] Since each roller group is located on the periphery of the channel, it forms resistance to the copper pipes passing through the channel on the outside in different directions. Each roller of the same roller group is arranged in a straight line. If any roller in the roller group is not positioned accurately, it will Affects the straightening reliability of the copper pipe passing through the channel. For example, if the rollers deviate towards the center of the channel, it may form a certain degree of obstruction for the copper tube to pass through the channel. If the rollers deviate toward the direction away from the center of the channel, it may Affects the reliability of copper pipe straightening
[0006] However, the two ends of the axles of each roller of the axle pivot are respectively connected with a positioning element, and the adjacent positioning elements are combined and positioned by means of each axle. In this way, it is difficult for the rollers constituting the roller unit to be in a straight line in space. Arrangement

Embodiment 2

[0035] The second embodiment is obtained by changing the first embodiment, and the second embodiment has the same structure as the first embodiment, and will not be repeated; if Figure 4 As shown, the second embodiment includes four roller units 21 and a bunch of sleeves 22, wherein each of the roller units 21 is juxtaposed, and each of the roller units 21 is surrounded by a long straight channel, which is not shown in the figure, and the channel is used Not shown in the figure of providing the metal pipe, the harness 22 is sheathed on each of the roller units 21 , thereby constraining each of the roller units 21 .

[0036] The main difference between Embodiment 2 and Embodiment 1 lies in the number of roller units. The present invention can further change the number of roller units to five or six or more, and the change of the number of roller units is based on the description of the present invention. Easily imagined quantity options.

Embodiment 3

[0037] The third embodiment is obtained by changing the first embodiment, and the third embodiment has the same composition as the first embodiment, and will not be repeated; if Figure 5 and Figure 6 As shown, the third embodiment includes four roller units 31 and a bunch of sleeves 32, wherein each of the roller units 31 is juxtaposed, and each of the roller units 31 is surrounded by a long straight channel 33, and the channel 33 is used to provide The metal pipe is not shown in the figure, and each of the roller units 31 is sheathed in the bundle sleeve 32 , thereby constraining each of the roller units 31 .

[0038] The harness 32 forms a plurality of restricting portions 321 inwardly, and each restricting portion 321 is respectively formed between each of the roller units 31 , thereby laterally restricting each of the roller units 31 .

Embodiment 4

[0039] Embodiment 4 is obtained by changing Embodiment 1, and Embodiment 4 has the same composition as Embodiment 1, and will not be described repeatedly; if Figure 7 and Figure 8 As shown, embodiment four comprises four roller units 41 and a bunch of sleeves 42, wherein, each of these roller units 41 is juxtaposed, and each of these roller units 41 surrounds and forms a long and straight channel, not shown in the figure, and the channel is used Not shown in the figure of providing the metal pipe, the harness 42 is sheathed on each of the roller units 41 , thereby constraining each of the roller units 41 .

[0040] One end of the harness 42 is provided with a first cap 422, and the other end is provided with a second cap 423, and the first cap 422 and the second cap 423 are screwed with the harness 42 respectively, so that the first cap 422 and the The second cap 423 relatively restricts each of the roller units 41 to prevent each of the roller units 41 from slipping out of...

Abstract

The present invention provides a pipe straightener, which consists of three roller wheel units (11) and a restraining sleeve (12), wherein each of the roller wheel units (11) is juxtaposed, and the roller wheel units (11) enclose and are configured to form a long straight-formed passageway (13). The passageway (13) is used to enable metal pipes to pass therethrough. The restraining sleeve (12) encloses and covers each of the roller wheel units (11), thereby restraining each of the roller wheel units (11). Each of the roller wheel units (11) is mainly structured from a wheel carrier (111) and a plurality of roller wheels (112). One side of the wheel carrier is a first side (113), and the other side is a second side (114). The first side (113) is adjacent to the passageway (13), and the second side (114) is adjacent to the restraining sleeve (12).

Description

technical field [0001] The present invention relates to a hand tool specially used for metal pipes, and more particularly to a pipe straightener, which is used to straighten metal pipes so that the metal pipes form a straight line or approach to a straight line. Background technique [0002] Copper pipes are widely used as conveying pipes for cold / heat medium, water, gas and other fluids. Copper pipes are metal pipes that are easy to bend. In the field of household and industrial piping, copper pipes are used in air conditioning systems, central heating systems and gas supply System, copper pipe is also used in the brake system and fuel system of the car. [0003] Metal tubes made of various metals, including copper tubes, are usually several meters in length, and are usually packaged in coiled form to improve the convenience of transportation and storage. When installing copper tubes, because copper tubes are easy to bend, installation Personnel usually try to straighten t...
