Description

Technical Field

[0001] The invention relates to the technical field of capillary heater processing, and in particular to a manufacturing device and a manufacturing method of a capillary heater. Background Art

[0002] Pipe heater is an energy-saving device for pre-heating materials. It is installed before the material equipment to directly heat the material, so that it can circulate and heat at high temperature, and ultimately achieve the purpose of saving energy. It is widely used in the pre-heating of heavy oil, asphalt, clean oil and other fuel oils. The capillary heater generally refers to a tubular heater with a diameter of ≤4mm.

[0003] When manufacturing a capillary heater, the assembled capillary needs to be shrunk so that the diameter of the capillary reaches the required diameter. The shrinking process is generally completed using a heat shrink tube machine. However, after the existing shrinking process of the tube, the tube needs to be manually removed from the position of the shrinking machine. During the removal process, the tube mouth will inevitably come into contact with the shrinking machine, which may easily cause the tube mouth to deform and affect the processing quality of the tube.

[0004] The Chinese invention patent with patent application number CN202210163294.4 records an automatic tube shrinking machine, which is equipped with a heating mechanism and heat-expanding silicone. In a shrinking mold, when the heating mechanism is working, the heat-expanding silicone expands to shrink the tube. When the heating mechanism stops working, the heat-expanding silicone shrinks to facilitate the removal of the tube and avoid damage to the tube. However, the staff still needs to manually remove the capillary in the above-mentioned device, and the surface temperature of the capillary after shrinking is relatively high. The staff is easily burned when removing the tube, which reduces the safety and reliability of the tube shrinking machine. Summary of the invention

[0005] The object of the present invention is to provide a manufacturing device and a manufacturing method for a capillary heater, so as to solve the problem that the existing capillary heater manufacturing device proposed in the above background technology requires workers to manually remove the capillary tube after shrinking during the tube shrinking process, which easily causes the workers to be scalded when removing the tube, thereby reducing the safety and practicality of the capillary manufacturing device.

[0006] To achieve the above object, the present invention provides the following technical solution: a method for manufacturing a capillary heater, comprising the following steps: S1: Open a mounting hole at one end of the magnesium powder rod, weld leads at both ends of the heating wire, and insert the heating wire into the mounting hole; S2: Weld a cap at one end of the outer tube, and then insert the magnesium powder rod into the outer tube; S3: Fill the mounting hole with magnesium oxide powder, and at the same time fill the gap between the magnesium powder rod and the outer tube with magnesium oxide powder and compact it; S4: performing a first tube shrinking process on the assembled capillary heater by a tube shrinking machine to reduce the outer diameter of the outer tube; S5: performing a second forging and shrinking process on the capillary heater after the first shrinking process by a forging machine to finally obtain a desired tube diameter; S6: The interior of the outer tube is subjected to moisture removal treatment, and then the end of the outer tube away from the sealing cap (60) is sealed with a sealing material.

[0046] Working principle: The outer tube 40 of the capillary heater to be shrunk is inserted into the rubber plug 232 and pressed against the circular plate 231, and then the capillary heater is pushed through the heating tube 31 and the tube shrinking die 4 by the lateral moving mechanism 21, and at the same time, the suction pump 6335 is started to blow hot air to the outer surface of the outer tube 40 through the air inlet pipe 34, the blowing pipe 35 and the multiple hot air pipes 33 to complete the heating work of the outer tube 40, and then the tube shrinking die 4 performs the first tube shrinking process on the heated outer tube 40; After the left end of the outer tube 40 passes through the tube shrinking die head 4, the output ends of the four third electric push rods 5222 push the two teams of arc clamping plates 521 to approach each other until the left end of the outer tube 40 is clamped, and then the second electric push rod 511 pulls the outer tube 40 to the left through the pulling plate 512 and the arc clamping plate 521, so that the guiding and pulling operation of the capillary heater can be completed together with the pushing component 2 to ensure the smooth progress of the tube shrinking process; When the outer tube 40 completely passes through the tube shrinking die 4, the output ends of the four third electric push rods 5222 respectively push the two teams of arc clamping plates 521 away from each other to gradually loosen the capillary heater, and then the right end of the capillary heater first moves downward and falls on the uppermost bracket 632 through the through groove 61, and as the arc clamping plate 521 continues to rotate until it completely enters the receiving groove 5221, the left end of the capillary heater will also fall into the bracket 632, and then the suction pump 6335 can form a negative pressure between the inner wall of the bracket 632 and the outer wall of the capillary heater through the air outlet pipe 6334, the first air cavity 6331, the second air cavity 6332 and the circular hole 6333 to conveniently suck the capillary heater tightly; Then, the second motor 621 drives the plurality of brackets 631 to rotate through the rotating plate 622, so that the capillary heater in the bracket 632 rotates from the uppermost side to the lowermost side, and then closes the solenoid valve in the lowermost second air cavity 6332, so that the capillary heater in the lowermost bracket 632 can fall into the placement box 643; Then, the first moving unit 641 drives the placement box 643 to move back and forth, and cooperates with the second moving unit 642 to drive the tubes stacked in the placement box 643 to move downward the same distance each time the placement box 643 moves to the front or back side, so that the capillary heaters can be neatly stacked layer by layer, thus completing the initial shrinking process of the capillary heater.
