Problems solved by technology
[0003] The present invention mainly provides an anti-sagging resistance wire drawing device and process that has a simple process, and the hardness value of the resistance wire can be changed through adjustment of the process, so as to meet the control requirements of the sag distance of the resistance wire, and solve the problems of the prior art. The sagging distance of the resistance wire of the exposed heater in the electric heater cannot be controlled, so it is very easy to cause leakage, and in severe cases, it will directly endanger personal safety and other technical problems.

Embodiment
[0023] like image 3 As shown, a wire drawing device for an anti-sagging resistance wire of the present invention includes a wire drawing device 2, and the wire drawing device 2 further includes an incoming wire roller 21 and an outgoing wire roller 22 arranged vertically side by side, both of which are pagoda-shaped with a small top and a large bottom. , between the incoming line roller 21 and the outgoing line roller 22, the eye module group 23 with several front eye molds 231 is arranged in parallel. The molds 231 are equidistantly staggered along the vertical direction on the eye mold group 23, and the input ends of the adjacent eye molds 231 are opposite to the incoming wire roller 21 and the outgoing wire roller 22 respectively, and the eye molds 231 gradually decrease in area reduction from top to bottom. Small, the upper end of the incoming wire roller 21 is the input end of the resistance wire 1, the lower end of the outgoing wire roller 22 is the output end of the re...

Abstract
The invention discloses a wire-drawing device, and provides a wire-drawing device and technology of an anti-sagging resistance wire. Through adjustment of the technology process, the hardness value ofthe resistance wire can be changed to meet controlling requirements of the slagging distance of the resistance wire. The technical problems in the prior art that the slagging distance of the resistance wire of an exposing type heater can not be controlled, electric leakage is liable to occur, and personal safety can be directly affected in serious situations are solved. The wire-drawing device comprises a wire-drawing device body and a wire-drawing semi-finished product of the resistance wire guided from the wire-drawing device body. A solid solution processing furnace and a small diameter reduction wire-drawing device are arranged outside the wire-drawing device body corresponding to the wire-drawing semi-finished product. The wire-drawing semi-finished product is subjected to wire-drawing processing in the small diameter reduction wire-drawing device after the solid solution processing in the solid solution processing furnace. A wire-drawing finished product of the resistance wire is guided out from the output end of the small diameter reduction wire-drawing device.
Description
technical field [0001] The invention relates to a wire drawing device, in particular to an anti-sagging resistance wire drawing device and process which has a simple process and can change the hardness value of the resistance wire through the adjustment of the process to meet the requirements for controlling the sag distance of the resistance wire. Background technique [0002] The exposed heater is a heater in which the resistance wire is exposed in the air and the resistance wire is fixed to the support plate through an insulating bracket. Because the resistance wire is exposed to the air, there is generally forced ventilation, and the actual use temperature of the resistance wire is between 300°C and 600°C. With the development of home appliance design in the direction of intensification and miniaturization, the gap between the resistance wire and the support plate is usually only 8mm. Once the resistance wire sags too far, the distance between the resistance wire and the...
