Description

Technical Field

[0001] The utility model relates to the technical field of electric heating pipe processing, in particular to an electric heating pipe processing device convenient for adjusting the bending radian. Background Technique

[0002] An electric heating pipe is an electrical component that specifically converts electrical energy into heat energy. It uses a metal pipe as the outer shell, including stainless steel and copper pipes. Along the central axis of the pipe, spiral electric heating alloy wires are evenly distributed. Nickel-chromium and iron-chromium alloys are filled and compacted in the gaps with magnesia sand having good insulation and heat conduction performance. The two ends of the pipe orifice are sealed with silica gel. This metal-sheathed electric heating element can heat air, metal molds, and various liquids; due to its high electric-heat conversion efficiency, small thermal inertia, convenient control, small volume, and light weight, it is widely used in various heating occasions.

[0003] Chinese Patent CN215089969U discloses a pipe bending device for electric heating pipe processing, including a table board. One side of the outer wall of the top of the table board is welded with a guiding column, and an arc-shaped groove is opened on one side of the table board close to the guiding column. A column rod is welded on the inner wall of the bottom of the table board close to the arc-shaped groove, and a sector plate is movably connected to the outer side wall of the column rod through a bearing. A sector gear plate is welded on the outer side wall of the sector plate, and a motor is installed on the inner wall of the bottom of the table board through bolts. The output end of the motor is connected with a driving gear by a flat key, and the driving gear meshes with the sector gear plate. In the utility model, the motor drives the sector plate to rotate along the column rod through the driving gear and the sector gear plate, so that the bending column slides along the arc-shaped groove, and the electric heating pipe is bent with the guiding column as the fulcrum along with the movement of the bending column. When the sector plate moves along the column rod, the positioning column slides along the positioning groove, making the sector plate drive the bending column to move along the arc-shaped groove more stably and reliably.

[0004] However, the above scheme can only bend the heating pipe into a fixed radian and cannot bend it into any radian. When it is necessary to bend the heating pipe into different radians, the bending device needs to be replaced, which is time-consuming and laborious and increases the enterprise cost.

Limiting holes are arranged on both the left and right sides of the sliding holes. Two sliders are slidably connected in the two sliding holes through threaded rods;

[0007] The upper ends of both sliding blocks are rotatably connected with bent plates. A push head is arranged on one side between the two bent plates, and the push head is fixedly installed on the output end of the electric push rod.

It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: an electric heating pipe processing device convenient for adjusting the bending arc, including: an operating table 1 and an electric push rod 17. The electric push rod 17 is located on one side of the upper end of the operating table 1. A supporting block 16 is fixedly installed on one side of the upper end of the operating table 1. One end of the electric push rod 17 is fixedly installed on one side of the supporting block 16. The output end of the electric push rod 17 is fixedly installed with a pushing head 18. The electric push rod 17 and the pushing head 18 are located at the center of the operating table 1 in the left-right direction, and an arc groove is opened on one side of the pushing head 18, which is convenient for cooperating with the electric heating pipe and pushing the electric heating pipe.

[0024] Sliding holes 2 are symmetrically opened at the front and rear ends on the other side of the upper end of the operating table 1. Limiting holes 3 are provided on both the left and right sides of each sliding hole 2. Fixing blocks 4 are fixedly installed at the front and rear ends on the lower side of the other end of the operating table 1. The threaded rod 5 is rotatably connected between the two fixing blocks 4 through a rotating seat, and one end of the threaded rod 5 passes through one of the fixing blocks 4 and is fixedly installed with an anti-sliding block 6. The threads at the front and rear ends of the threaded rod 5 are symmetrically arranged, and the threaded rod 5 can be driven to rotate at the lower end of the operating table 1 by holding the anti-sliding block 6.

[0025] Symmetrically threaded at the front and rear ends of the threaded rod 5 are threaded barrels 7. Fixedly installed at the upper end of the threaded barrel 7 is a plug-in block 8. The lower end of the slider 9 slides through the sliding hole 2 and is provided with a plug-in groove 10. The upper end of the plug-in block 8 is inserted into the plug-in groove 10 and fixed by bolts, which serves to facilitate the disassembly and assembly of the slider 9. Fixedly installed at the upper end of the slider 9 is a rotating shaft 11. Threaded holes 12 are provided at the upper end of the rotating shaft 11. The bent disc 13 is rotatably sleeved on the outer wall of the rotating shaft 11 through a bearing. The bent disc 13 is rotatably arranged on the upper end of the slider 9 through a bearing and the rotating shaft 11. By holding the anti-slip block 6 to drive the threaded rod 5 to rotate at the lower end of the operating table 1, the threaded rod 5 can simultaneously drive the two bent discs 13 to move synchronously inward or outward, arbitrarily adjusting the distance between the two bent discs 13, and the electric heating tube can be bent into different arcs.

[0026] First, put the bent disc 13 on the rotating shaft 11, and then threadedly connect and fix the bolt 15 in the threaded hole 12. The fixing thread 15 is located at the upper end of the bent disc 13 to fix the bent disc 13, which serves to facilitate the replacement of different bent discs and the bending of electric heating tubes with different diameters.

The fixing thread 15 is located at the upper end of the bent disc 13 to fix the bent disc 13. By holding the anti-slip block 6 to drive the threaded rod 5 to rotate at the lower end of the operating table 1, the threaded rod 5 can simultaneously drive the two bent discs 13 to move synchronously inward or outward, arbitrarily adjusting the distance between the two bent discs 13, and the electric heating tube can be bent into different arcs.
