Description

Technical Field

[0002] Titanium alloy materials have the advantages of high specific strength, good high and low temperature properties and good corrosion resistance. Household cabinets are usually made of alloy materials. Various different parts need to be welded during the production process to form cabinets. High-frequency brazing technology is often used in the production of kitchen utensils. High-frequency brazing refers to the use of high-frequency current flowing through the metal to generate heat to heat the weld to the melting temperature of the alloy brazing material. However, the metal being welded has not yet reached the melting temperature. The low-melting point alloy bonds the two metals together through strong surface tension, and a solid weld is formed after cooling.

[0003] However, traditional welding devices for titanium alloy kitchen utensils are mostly used by workers by hand. Since there is no structural device for accurately positioning the weld, workers will experience jitter and deviation when welding over long distances. Long-term hand-held work also causes workers to become tired. In addition, the existing technology does not have a device for cleaning the weld before welding and for handling smoke during welding, which affects the health of the workers and affects the work results.

[0039] like Figure 3 and Figure 4As shown, the bottoms of the first straight cylinder 41 and the second straight cylinder 43 are connected with a rubber cover disc 44, which is arranged in a horizontal state, and the two rubber cover discs 44 are arranged with their openings facing downwards. The inner walls of the first straight cylinder 41 and the second straight cylinder 43 are provided with rubber plugs 45, and the rubber plugs 45 are in contact with the inner walls of the first straight cylinder 41 and the second straight cylinder 43. A pull rod 46 is fixedly installed on the tops of the two rubber plugs 45, and the pull rod 46 is arranged in a vertical state, and then the pull rod 46 moves up to drive the rubber plugs 45 to move up synchronously, so that negative pressure is generated in the first straight cylinder 41 and the second straight cylinder 43.

7. The device for accurately positioning a weld seam for welding titanium alloy kitchenware according to claim 6, characterized in that: A purge mechanism (6) is provided on one side of the air outlet box (57), the purge mechanism (6) comprising a plurality of air blowing pipes (61) connected to one side of the air outlet box (57), the plurality of air blowing pipes (61) being arranged obliquely downward, a plurality of rotating rods (62) being rotatably mounted on the outer wall of the air outlet box (57), a plurality of air flicking plates (63) being fixedly mounted on the outer walls of the plurality of rotating rods (62), the plurality of air flicking plates (63) being arranged in an interlaced manner with the air blowing pipes (61), a rotating disk (64) being fixedly mounted on the bottom of the rotating rod (62), the rotating disk (64) being arranged obliquely downward, and bristles (65) being fixedly mounted on the outer wall of the rotating disk (64).

8. A method for using a weld seam precision positioning device for welding titanium alloy kitchenware, according to claim 7, characterized in that: The following steps are involved: Step 1: inserting the welding gun head (2) into the limiting ring (31), and then adjusting the welding gun head (2) to the initial position of the welding seam, thereby adjusting the position of the limiting sliding box (33) through the limiting push rod (32), so that the welding gun head (2) is always aligned with the welding seam, and sliding the distance plate (35) and the marking spotlight (36) so that the marking spotlight (36) is aligned with the end position of the welding seam; Step 2: Rotate the dial ring (48) to drive the two card support rods (47) to move upward and get stuck through the two top convex plates (49), that is, the pull rod (46) moves upward to drive the rubber plug (45) to generate negative pressure in the first straight cylinder (41) and the second straight cylinder (43).
