Description

Simple pipe bending device

Technical Field

The utility model relates to a simple and easy swan neck system.

Background

The steel pipe is a commonly used material, and is a certain equipment which needs to be welded by the steel pipe in life, but for the general public, when the steel pipe is bent, the steel pipe cannot be bent well due to the lack of professional pipe bending equipment.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a simple and easy swan neck system has effectively solved the problem of pointing out among the background art.

The utility model adopts the technical proposal that:

the utility model provides a simple and easy swan neck system, includes the base, sets up the tight pulley and the removal wheel in base top to and driving handle, the tight pulley pass through the bolt fastening on the base, the center of tight pulley is fixed with a first bearing, the center of removing the wheel is fixed with a second bearing, driving handle's bottom is fixed with first spliced pole and second spliced pole, the inner circle of first spliced pole and first bearing fixed, the inner circle of second spliced pole and second bearing fixed, the base is fixed with a lateral part baffle at the lateral part of tight pulley.

Preferably, an annular arc-shaped groove is formed in the outer arc surface of each of the fixed wheel and the movable wheel.

The arc wall is laminated with the surface of steel pipe more, has increased the contact surface of steel pipe with the arc wall, reduces the damage to the steel pipe surface when the return bend, and simultaneously, the design of arc wall steel pipe front end upwards ejecting when can preventing the return bend, influences the quality of return bend.

Preferably, a sleeve which is connected with the driving handle in a sliding mode is arranged outside the driving handle, and a fastening bolt is arranged between the sleeve and the driving handle.

The sleeve is arranged on the driving handle, so that the driving handle can be prolonged according to actual needs, and the driving handle is more labor-saving and is also convenient to carry.

Preferably, a top baffle is fixed on the top of the side baffle at the side close to the fixed wheel.

The top baffle can prevent that the steel pipe afterbody from upwards ejecting when the return bend, influences the quality of return bend.

Preferably, the fixed wheel is provided with at least two fixed holes, the top of each fixed hole is of a counter bore structure, the base is provided with a screw hole matched with the fixed holes, counter bore bolts are matched and arranged in the fixed holes, and the front ends of the counter bore bolts penetrate through the fixed holes and then are matched and fixed with the screw holes.

The fixed wheel is fixed through the counter bore structure, and the structure is more reasonable.

The utility model discloses simple structure can adopt conventional material to make, can be applicable to the quick bending of ordinary steel pipe, only needs to fix the base when using and can carry out the return bend operation, and it is very convenient to use, and portable.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description of specific embodiments thereof, which is illustrated in the accompanying drawings.

Example 1

As shown in fig. 1-3, a simple pipe bending device, includes base 1, sets up tight pulley 2 and the removal wheel 3 in base 1 top to and driving handle 4, tight pulley 2 pass through the bolt fastening on base 1, the center of tight pulley 2 is fixed with a first bearing 5, the center of removing wheel 3 is fixed with a second bearing 6, driving handle 4's bottom is fixed with first spliced pole 7 and second spliced pole 8, first spliced pole 7 fixed with the inner circle of first bearing 5, second spliced pole 8 fixed with the inner circle of second bearing 6, base 1 is fixed with a lateral part baffle 9 at the lateral part of tight pulley 2.

And an annular arc-shaped groove 10 is formed in the outer arc surfaces of the fixed wheel 2 and the movable wheel 3.

The outside of the driving handle 4 is provided with a sleeve 11 which is connected with the driving handle 4 in a sliding way, and a fastening bolt 12 is arranged between the sleeve 11 and the driving handle 4.

The top of the side barrier 9 is fixed with a top barrier 13 at the side close to the fixed wheel 2.

The fixing wheel 2 is provided with at least two fixing holes 14, the tops of the fixing holes 14 are of a counter bore structure, the base 1 is provided with screw holes 15 matched with the fixing holes 14, counter bore bolts 16 are arranged in the fixing holes 14 in a matched mode, and the front ends of the counter bore bolts 16 penetrate through the fixing holes 14 and then are fixed with the screw holes 15 in a matched mode.

The utility model discloses a theory of operation:

firstly fix base 1, then through driving handle 4 will remove the wheel 3 and rotate to the opposite side of fixed wheel 2 for lateral part baffle 9, then penetrate the steel pipe between fixed wheel 2 and the removal wheel 3 from the one side that lateral part baffle 9 is close to fixed wheel 2, and confirm crooked position, rethread driving handle 4 makes removal wheel 3 press to the steel pipe, bend the steel pipe, until bending the steel pipe to required angle, stop crooked, after crooked completion, will remove wheel 3 again and rotate to the opposite side of fixed wheel 2 for lateral part baffle 9 through driving handle 4, at this moment, take out crooked steel pipe can, when crooked, if the steel pipe is harder when leading to the operation hard, the accessible adjusts sleeve pipe 11 and prolongs the length of driving handle 4, thereby reach laborsaving purpose of operation.

Finally, it should be noted that the above-mentioned embodiments are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
