Description

Technical Field

[0001] The utility model belongs to the technical field of silicon steel plate weld tempering devices, in particular to an induction type silicon steel plate weld tempering device. Background Art

[0002] Grain-oriented silicon steel refers to cold-rolled electrical steel containing 2.9% to 3.5% Si, with a certain regularity and direction in the crystal structure of the steel plate. After welding, the steel strip joints of oriented silicon steel can be tempered to reduce stress concentration in the weld. The weld reaches the tempering temperature, reducing the brittleness of the weld, improving the strength, and reducing the susceptibility to cracking of the weld, thereby extending the service life of the weld.

[0003] A Chinese patent (CN201520405192.4) discloses a device for localized high-temperature tempering of welds on continuous strip production lines. This device is used for in-line heat treatment of welds during the narrow lap welder welding process within a rolling mill. The device incorporates a high-frequency induction heater positioned behind the welding wheel of a resistance welder. This device has a simple structure and is easy to use, enabling in-line heat treatment of welds during the welding process to eliminate welding stress.

[0004] Currently, the position of the induction heater is fixed, and the time it takes for the steel strip to reach a preset temperature through induction heating needs to be matched with the corresponding welding speed, which limits the welding speed and affects the welding efficiency.

[0025] See also Figure 1-3 The utility model provides a technical solution: an induction-type silicon steel plate weld tempering device, comprising a fixed induction heater 1, a movable induction heater 2 and a movable driving mechanism 3, wherein the fixed induction heater 1 is fixedly connected to a welding machine movable frame 4, the welding machine movable frame 4 is provided with two welding wheels 5, the movable induction heater 2 is slidably connected to a slide rail 6 of the welding machine movable frame 4, the fixed induction heater 1 is located between the movable induction heater 2 and the two welding wheels 5, and the movable driving mechanism 3 connects the slide rail 6 and the movable induction heater 2;

[0026] The movable driving mechanism 3 includes a servo motor 31, a spur rack 32 and a driving gear 33. The spur rack 32 is fixedly connected to the slide rail 6. The servo motor 31 is fixedly connected to the movable induction heater 2. The driving gear 33 is installed on the output end of the servo motor 31, and the driving gear 33 is engaged with the spur rack 32. The rotation of the servo motor 31 drives the driving gear 33 to rotate. The interaction between the driving gear 33 and the spur rack 32 causes the movable induction heater 2 to slide along the slide rail 6, thereby performing secondary heating on different positions of the weld.

[0027] A contact sensor 7 is provided at both ends of the slide rail 6. The contact sensor 7 is electrically connected to the servo controller of the servo motor 31. After the contact sensor 7 obtains a signal, it is sent to the servo controller of the servo motor 31.

[0029] The two welding wheels 5 are arranged symmetrically.

[0030] Working principle: Oriented silicon steel is butt-welded at the welding wheel 5. Secondly, the fixed induction heater 1 performs preliminary tempering heating on the weld after welding. The movable driving mechanism 3 drives the movable induction heater 2 to slide along the slide rail 6, that is, the servo motor 31 rotates to drive the driving gear 33 to rotate. The interaction between the driving gear 33 and the spur rack 32 makes the movable induction heater 2 slide along the slide rail 6. During the process, the contact sensor 7 obtains the signal and sends it to the servo controller of the servo motor 31. The servo controller can control the servo motor 31 to change the rotation direction, thereby making the movable induction heater 2 reciprocate, so that the movable induction heater 2 can supplementally heat the weld after welding. Even if the welding speed is increased, the weld can reach the tempering temperature, thereby improving the welding efficiency.
