Technical Field

[0001] The utility model relates to the technical field of pipe bending equipment, in particular to a pipe bender for heating pipe processing. Background Technique

[0002] A heating pipe is formed by loading an electric heating wire into a steel pipe, filling the gap with magnesium oxide powder having good thermal conductivity and insulation, and then shrinking the pipe, and then processed into various shapes required by users. It has the characteristics of simple structure, high thermal efficiency, and good mechanical strength, and has good adaptability to harsh environments. It can be used for heating various liquids and acids, alkalis and salts, and at the same time is suitable for melting low-melting-point metals. It has the advantages of small size and high power.

[0003] A return-shaped heating pipe is a common shape of heating pipe, which is formed by bending the heating pipe multiple times to form a shape similar to a safety pin. However, during the bending process of the return-shaped part, the bent part may rub against the outer wall of the heating pipe, resulting in damage to the surface of the heating pipe, and then the qualified rate of the finished product decreases, which is not conducive to the production efficiency of the enterprise. Content of the Utility Model

[0004] To solve the technical problems in the background technique, the utility model proposes a pipe bender for heating pipe processing.

[0005] A pipe bender for heating pipe processing proposed by the utility model includes a turntable and a rotating disc. The rotating disc is installed on the movable end of the turntable. A central column is installed in the middle of the rotating disc. A bending part is detachably installed on the upper end surface of the rotating disc. The bending part and the central column are arranged opposite to each other to form a heating pipe placement channel, and the bending part can rotate relative to the rotating disc.

[0006] As a further optimized scheme of the utility model, a cushion block is installed at the bottom of the bending part. The cushion block presses on the upper end surface of the rotating disc and is fixed by fasteners.

[0007] As a further optimized scheme of the utility model, an installation groove is opened on the rotating disc. The length direction of the installation groove is perpendicular to the axis of the central column, and the side of the installation groove away from the central column has an opening. The fastener is preferably a bolt. The bolt rod passes through the installation groove and the cushion block and is locked by a nut.

[0008] As a further optimized scheme of the utility model, the bending part includes a central rod and a sleeve. The central rod is detachably installed on the upper end surface of the rotating disc.

[0022] Please refer to Figure 1 and Figure 2 , a pipe bender for heating pipe processing, which is mainly applicable to the bending operation of the loop heating pipe. Specifically, it includes a turntable 1 and a rotating disc 2. The rotating disc 2 is installed on the movable end of the turntable 1. A central column 3 is installed in the middle of the rotating disc 2. A bending part 4 is detachably installed on the upper end surface of the rotating disc 2. The bending part 4 is arranged opposite to the central column 3 to form a heating pipe placement channel, and the bending part 4 can rotate relative to the rotating disc 2;

[0023] During use, only need to place the heating pipe in the placement channel, and then drive the bending part 4 to rotate through the rotating disc 2, so that the bending part 4 bends the heating pipe. During the bending process, since the bending part 4 is in contact with the surface of the heating pipe, the bending part 4 rotates relative to the rotating disc 2, reducing the friction between the bending part 4 and the surface of the heating pipe, thereby avoiding damage to the surface of the heating pipe;

[0024] It should be noted that as Figure 1As shown in the figure, during the bending process where the turntable 2 drives the bending part 4 to rotate, the bending part 4 may come into contact with the free end of the loop-shaped heating tube. At this time, through the rotatable design of the bending part 4, it can also play a certain role in preventing wear;

[0025] Specifically, a cushion block 5 is installed at the bottom of the bending part 4. The cushion block 5 is pressed on the upper end surface of the turntable 2 and fixed by fasteners;

[0026] Furthermore, an installation groove 6 is formed on the turntable 2. The length direction of the installation groove 6 is perpendicular to the axis of the central column 3, and one side of the installation groove 6 away from the central column 3 has an opening. The fastener is preferably a bolt. The bolt rod passes through the installation groove 6 and the cushion block 5 and is locked by a nut, which facilitates the disassembly and assembly of the cushion block 5, thereby facilitating the quick assembly of the bending part 4 to the upper end surface of the turntable 2, so as to replace the bending part 4 and adjust the clearance distance between the bending part 4 and the central column 3, thus facilitating the bending operation of heating tubes of multiple specifications;

[0027] Furthermore, the bending part 4 includes a central rod and a sleeve. The central rod is detachably installed in the middle of the upper end surface of the turntable 2. The sleeve is rotatably sleeved on the central rod, and there is a rotational connection between the outer peripheral surface of the sleeve and the outer wall of the heating tube;

[0028] Furthermore, the central rod is a threaded rod. The bottom end of the central rod is fixed on the cushion block 5. The sleeve is rotatably sleeved on the central rod, and the top end of the central rod is limited by a nut, so as to axially limit the sleeve. While facilitating the disassembly and assembly of the sleeve, it does not affect the rotation of the sleeve;

[0029] Furthermore, the sleeve is stacked by multiple collar rings, and the specified number and specifications of collar rings can be selected according to the specifications of the heating tube to be processed, improving the actual use convenience;

[0030] In summary, for the tube bender for processing heating tubes proposed by the present utility model, by installing a bending part 4 opposite to the central column 3 on the upper end surface of the turntable 2, and utilizing the characteristic that the bending part 4 can rotate relative to the turntable 2, when the turntable 2 drives the bending part 4 to rotate to bend the heating tube, the outer peripheral surface of the bending part 4 comes into contact with the surface of the heating tube and rotates. Without affecting the normal bending, it avoids friction with the outer wall of the heating tube, thereby preventing damage to the surface of the heating tube, thus improving the actual qualified product rate and being beneficial to the production efficiency of the enterprise.
