An online quenching tank lengthening structure

Abstract

This utility model discloses an extended structure for an online quenching water tank, relating to the technical field of online quenching in forward extrusion. It solves the problem that the original quenching water tank is far from the extruder outlet, resulting in long product lengths remaining outside the tank after extrusion and significant heat loss before quenching. In this utility model, a water tank body is installed at the front end of the original quenching water tank, extending the length of the online quenching water tank. A return water tank is machined on the water tank body to achieve drainage. The baffle plate serves to block water, and the anti-splash bottom plate is tilted upwards to allow splashed water to flow back into the return water tank. By extending the length of the online quenching water tank, this utility model shortens the distance between the water tank and the extruder outlet, reduces the length of product remaining outside the tank after extrusion, and allows extruded products to enter the quenching water tank earlier, reducing heat loss before quenching.

Description

Technical Field

[0001] This utility model relates to the technical field of online quenching of forward extrusion, and in particular to an extended structure for an online quenching water tank. Background Technology

[0002] Solution hardening is the most common method for improving the performance of aluminum alloys. It is generally divided into two types: offline quenching and online water quenching. Both methods involve cooling the aluminum alloy at high temperatures with cold water to achieve a solution hardening effect. Especially for alloys undergoing forward extrusion, online quenching can be implemented, significantly improving production efficiency. However, during design and installation, factors such as floor space and outlet length must be considered, resulting in the online quenching water tank being installed far from the extrusion press outlet. This causes a significant portion of the product to not enter the quenching tank for cooling after extrusion, leading to insufficient solution hardening, material waste, reduced yield, and increased costs.

[0036] Based on the above, this utility model also has the following embodiments:

[0037] In a further embodiment of this utility model, the structural modification of the extended online quenching water tank in this utility model uses 304 stainless steel for all welding connections. First, a water tank pressure plate 3 for sealing is welded to the end of the original quenching water tank 1 of the equipment to level the end face of the original quenching water tank 1. Second, a water tank body 2 is welded from a 304 stainless steel plate, and a water tank pressure plate 3 for sealing is welded to one end of the water tank body 2. The size of the water tank pressure plate 3 on the water tank body 2 is the same as the width of the pressure plate 3 on the original quenching water tank 1 of the equipment. Multiple through holes are drilled on both the water tank pressure plate 3 on the main body 2 and the water tank pressure plate 3 on the original quenching water tank 1 of the equipment. The average distance between adjacent through holes is 100mm. The positions of the multiple through holes on the water tank pressure plate 3 on the main body 2 and the water tank pressure plate 3 on the original quenching water tank 1 of the equipment correspond to each other, so as to facilitate the insertion of the bolt fastening assembly 10. A layer of soft rubber 12 is placed between the water tank pressure plate 3 on the main body 2 and the water tank pressure plate 3 on the original quenching water tank 1 of the equipment. Multiple bolt fastening assemblies 10 are used to connect them to prevent water leakage. Slotted stainless steel square tubes 4 are welded to both sides of the inner center of the water tank body 2. Each slotted stainless steel square tube 4 has a 6mm wide groove along its longitudinal direction for installing water baffles 5. The welded slotted stainless steel square tubes 4 form a boundary, dividing the water tank body 2 into two parts. A return water tank 6 is welded to the bottom surface near the extruder outlet. A return water pipe connector 7 is welded to the side of the return water tank 8 near the water storage tank. The return water pipe connector 7 and the return water pipe 8 are secured with locking sleeves to prevent detachment and leakage. The other end of the return water pipe 8 is placed in the water storage tank. A splash-proof water base plate 9 is welded to the end of the water tank body 2 adjacent to the extrusion outlet. The splash-proof water base plate 9 has a 15° angle to facilitate the return of splashed water to the return water tank 6. This modification shortens the distance between the original quenching water tank 1 and the extruder outlet, reduces the length of product remaining outside the water tank after extrusion, and allows extruded products to enter the quenching water tank earlier, reducing heat loss before quenching. This can increase the yield by 3%-10%, significantly improving the yield rate.

[0038] In this utility model, a water tank body 2 is installed at the front end of the original quenching water tank 1 of the equipment, which extends the length of the online quenching water tank and shortens the distance between the water tank and the extruder outlet. At the same time, a return water tank 6 is processed on the water tank body 2 to realize the drainage function. By welding a slotted stainless steel square tube 4 inside the water tank body 2, the water baffle 5 can be quickly disassembled and assembled. The water baffle 5 can play the function of blocking water. A splash-proof water bottom plate 9 is welded to the front end of the water tank body 2. The splash-proof water bottom plate 9 is inclined upward so that the splashed water can flow back into the return water tank 6. The splash-proof water bottom plate 9 is an isosceles trapezoid, and its longer base side is welded to the front end of the water tank body 2.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model.
