Technical Field
The invention belongs to the technical field of metallurgical equipment, and particularly relates to an aluminum profile extrusion online quenching tuyere protection system which is suitable for aluminum profile extrusion online quenching.
Background
The on-line quenching is one of the very important links in the aluminum extrusion production process. When the aluminum material is extruded and quenched on line, due to the product characteristics of different shapes, different wall thicknesses and the like of the extruded aluminum material, once the quenching process is controlled improperly, the extruded section is bent and deformed, the bent and deformed section can easily damage the tuyere of the quenching equipment, and most typically, the bent and deformed section bends the tuyere or drops the tuyere. In addition, when on-line quenching, the quenching equipment is in a closed state, operators cannot know the bending state of the section in the quenching equipment, and even the whole quenching air box is damaged when the bending deformation is serious. The air nozzle is damaged to cause uneven quenching of the aluminum profile, so that the aluminum profile is easier to bend and can be repaired after production is stopped, the production efficiency is seriously influenced, and equipment is damaged. The problem is a common problem in the aluminum extrusion industry, and the current practice in the industry is to reserve a spare tuyere in advance, prepare a maintenance tool to reduce the production stop and repair time and reduce the influence on the production efficiency as much as possible, and no measure and method capable of fundamentally solving the problem exists.

Quenching tuyere protection device 5 include fixed bolster 11, fixed bolster 11 is fixed in the below of quenching upper air box 3, fixed bolster 11 passes through axis of rotation 12 and is connected with the one end of rotating connection board 13, the other end of rotating connection board 13 links together with tablet 15, tablet 15 is located the both sides of quenching tuyere 4, form a whole through the intermediate junction pole 16 is fixed between the tablet 15 of both sides, install proximity switch device 14 on the same high position of tablet 15's both sides, proximity switch device 14's signal end and lift drive 2 realize the communication linkage.
The height of the fixed connecting rod 16 is lower than that of the quenching tuyere 4.
The length of the induction plate 15 is equal to that of the upper quenching air box 3.
The invention has the beneficial effects that:
1. switching device 14 installs on the same high position of the both sides of response, and when tablet 15 droops naturally, tablet 15 can not sense proximity switch 14, and when the exogenic action, tablet 15 takes place to remove, no matter which side of tablet 15 is removed and all can be sensed by proximity switch 14.
2. Even if the extruded section 7 is bent, the bent extruded section 7 is firstly contacted with the middle connecting rod 16 of the quenching air nozzle protection device 5, so that the whole body formed by the sensing plate 15 and the middle connecting rod 16 is forced to rotate around the rotating shaft 12, the sensing plate 15 moves, the moved sensing plate 15 enables the proximity switch device 14 to be sensed and sent, the quenching upper air box lifting driving device 2 drives the quenching upper air box 3, the quenching upper air box outer cover 6 and the quenching air nozzle protection device 5 to ascend together until the quenching air nozzle protection device 5 is not contacted with the bent and deformed extruded section 7 any more, namely the sensing plate 15 is not acted by external force, and naturally resets and droops. Therefore, the design of the quenching air nozzle protection device 5 ensures that the extruded section 7 can not contact with the air nozzle, thereby solving the problem that the extruded section is easy to cause the damage of the air nozzle of quenching equipment after on-line quenching bending deformation, even the deformation damage of the whole quenching air box; seriously affecting the production efficiency and damaging the equipment.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an online quenching tuyere protection system for aluminum profile extrusion comprises a quenching upper air box lifting driving device 2, wherein the quenching upper air box lifting driving device 2 is installed on a quenching device bracket 1 through a fixed end of the quenching upper air box lifting driving device 2, a movable end of the quenching upper air box lifting driving device 2 is connected with a quenching upper air box 3, and an outer surface of the quenching upper air box 3 is sleeved with a quenching upper air box outer cover 6; a corresponding quenching roller way 8, a quenching lower air box 9 and a quenching water tank 10 are arranged on the ground right below the quenching upper air box 3; during extrusion, the quenching upper air box 3 and the quenching upper air box outer cover 6 descend to the right position, the quenching upper air box outer cover 6 and the quenching water tank 10 form a closed space, the quenching upper air box 3 and the quenching lower air box 9 quench the extruded section 7, and the extruded section 7 is extruded on a quenching roller table 8; a quenching air nozzle protection device 5 is arranged on the quenching upper air box 3.
As shown in fig. 2, the quenching tuyere protection device 5 comprises a fixed support 11, the fixed support 11 is fixed below the quenching upper air box 3, the fixed support 11 is connected with one end of a rotating connecting plate 13 through a rotating shaft 12, the other end of the rotating connecting plate 13 is connected with induction plates 15, the induction plates 15 are positioned at two sides of the quenching tuyere 4, and the induction plates 15 at the two sides are fixed together through an intermediate connecting rod 16 to form a whole; the proximity switch device 14 is installed at the same height position on both sides of the induction plate 15, and the signal end of the proximity switch device 14 is in communication linkage with the lifting driving device 2.
