Description

Technical Field

[0001] The utility model relates to the technical field of round tube processing equipment, in particular to a double-channel high-strength round tube induction quenching, tempering and cooling device. Background Art

[0002] During the actual processing, high-strength round tubes need to undergo surface quenching and tempering to enhance the surface strength of the tubes. During the quenching and tempering operations, the high-strength round tubes need to be pushed forward at a stable and uniform speed. In particular, the surface of the round tube is smooth and has low friction, making it easy to slip during the advancement process. Therefore, it is more difficult to advance forward at a stable and uniform speed. Previously, the applicant's patent CN115198078A disclosed a continuous induction quenching heat treatment equipment for automobile bumpers, which can adapt to the processing requirements of automatic loading, conveying, speed separation, straight forward conveying, quenching, tempering, cooling and unloading of automobile bumpers of different models and sizes, and can achieve stable straight forward conveying of automobile bumpers, preventing deviation and slipping during quenching and tempering. However, this patent cannot simultaneously achieve stable advancement of two round tubes and simultaneous quenching, tempering, cooling and other operations, resulting in low production efficiency and needing improvement. Utility Model Content

[0005] In the above technical solution, during actual operation, the round tubes that need to be quenched are placed in the first friction conveying channel and the second friction conveying channel respectively, and then are pressed accordingly by the pressing roller assembly. The power output motor in the power drive mechanism drives the power output reduction gear to drive the power output transmission rod to rotate, and the active output gear on the power output transmission rod drives the four synchronous transmission rods to rotate respectively through the synchronous belt and the synchronous transmission gear. When the friction wheels on the first synchronous transmission rod and the second synchronous transmission rod rotate, they cooperate with the pressing roller assembly to make the round tubes in the first friction conveying channel stably and uniformly pushed forward. At the same time, when the friction wheels on the third synchronous transmission rod and the fourth synchronous transmission rod rotate, they cooperate with the pressing roller assembly to make the round tubes in the first friction conveying channel stably and uniformly pushed forward. The roller assembly enables the round tube in the second friction conveying channel to move forward stably and at a uniform speed. When the round tube in the first friction conveying channel passes through the first quenching mechanism, it is quenched by the first quenching mechanism. When the round tube in the second friction conveying channel passes through the second quenching mechanism, it is quenched by the second quenching mechanism.

A universal roller is mounted at the bottom of each universal wheel mounting post, and a circular tube shield is mounted between two longitudinally distributed universal rollers. During actual operation, the press cylinder drives the press roller mounting frame downward, so that the universal rollers mounted on the four universal wheel mounting posts arranged downwardly in a square pattern come into contact with the top of the circular tube in the first friction conveying channel and the second friction conveying channel. Then, in conjunction with the rotation of the friction wheel, the circular tube can be continuously and stably moved forward under the action of friction.

[0011] The beneficial effects of a dual-channel high-strength round tube induction quenching, tempering, and cooling device provided by the utility model are as follows: the dual-channel high-strength round tube induction quenching, tempering, and cooling device has a reasonable design and a simple structure, can realize the stable and uniform forward propulsion of the dual round tubes, and simultaneously realize the stable propulsion of the two round tubes and the simultaneous quenching, tempering, cooling and other operations, with high production efficiency. In actual work, the round tubes to be quenched are respectively placed in the first friction conveying channel and the second friction conveying channel, and then correspondingly pressed by the pressing roller assembly. The power output motor in the power drive mechanism drives the power output reduction box to drive the power output transmission rod to rotate. The active output gear on the power output transmission rod drives the four synchronous transmission rods to rotate respectively through the synchronous belt and the synchronous transmission gear. When the friction wheels on the first synchronous transmission rod and the second synchronous transmission rod rotate, they cooperate with the pressing roller assembly to make the round tubes located in the first friction conveying channel stably and uniformly propel forward. At the same time, when the friction wheels on the third synchronous transmission rod and the fourth synchronous transmission rod rotate, they cooperate with the pressing roller assembly. This makes the round tube in the second friction conveying channel also move forward stably and uniformly. When the round tube in the first friction conveying channel passes through the first quenching mechanism, it is quenched by the first quenching mechanism. When the round tube in the second friction conveying channel passes through the second quenching mechanism, it is quenched by the second quenching mechanism. When the round tube after quenching passes through the tempering mechanism, the tempering mechanism can simultaneously temper and cool the first friction conveying channel and the second friction conveying channel. The tempering cooling water delivery mechanism continuously delivers cooling water to the spray pipe in the tempering mechanism. The cooling water is collected through the water collecting tank and then returned to the tempering cooling water delivery mechanism, thereby realizing the recycling of cooling water.
