Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of quenching protection racks, specifically a waterproof protection rack for vertical quenching. Background Technology
[0002] A quenching furnace is a furnace used to heat workpieces before quenching. Quenching involves placing the workpiece inside the furnace, heating it to a quenching temperature above the critical point, holding it for a period of time, and then quickly removing the workpiece from the furnace and immersing it in a quenching solution for further quenching. It is commonly used for quenching extruded aluminum alloy tubes, bars, and profiles.
[0003] Due to budget or space constraints, some domestic vertical quenching furnaces only have one quenching water tank, which serves both as a quenching tank and a transfer tank. This means that after the product is hoisted onto the furnace frame, it is immersed in the quenching water tank and then lifted into the furnace. The product entering the furnace with water presents a risk of high-temperature oxidation, reducing product performance, and lacks waterproofing capabilities.
[0004] Now, a novel waterproof protective frame for vertical quenching is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a vertical waterproof protective frame for quenching, so as to solve the problem mentioned in the background art of not having the function of waterproofing workpieces.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof protective frame for vertical quenching, comprising a vertical furnace hanging frame, a protective sleeve mounting frame disposed below the vertical furnace hanging frame, multiple sets of waterproof protective sleeves disposed inside the protective sleeve mounting frame, concave clips fixedly connected to the outer side of the waterproof protective sleeves, two sets of mounting bolts inserted into the top of the concave clips, multiple sets of pre-cut screw grooves opened at the top of the protective sleeve mounting frame, four sets of external slots opened on the outer side of the vertical furnace hanging frame, fixed pins fixedly connected inside the external slots, a connecting plate vertically disposed inside the external slots, a bushing bolted to the bottom of the outer side of the connecting plate, a counterweight welded to the top of the outer side of the connecting plate, and a right-angle hook welded to the top of the inner side of the connecting plate.
[0007] As a further technical solution of this utility model, the vertical center lines of the vertical furnace hanging frame and the protective sleeve mounting bracket coincide, and there is a distance between the vertical furnace hanging frame and the protective sleeve mounting bracket.
[0008] As a further technical solution of this utility model, the bottom of the waterproof protective sleeve is closed, and the top of the waterproof protective sleeve is open.
[0009] As a further technical solution of this utility model, the shape and size of the concave clip inside are adapted to the shape and size of the protective sleeve mounting bracket outside, and the mounting bolt passes through the concave clip and extends into the interior of the pre-opened screw groove.
[0010] As a further technical solution of this utility model, the mounting bolt and the pre-cut thread groove are positioned and sized accordingly, and the external thread of the mounting bolt and the internal thread of the pre-cut thread groove are matched.
[0011] As a further technical solution of this utility model, the fixing pin passes through the interior of the bushing, and the outer diameter of the fixing pin is smaller than the inner diameter of the bushing.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the vertical quenching waterproof protective frame not only realizes the function of waterproofing the workpiece, but also realizes the function of easy disassembly and assembly of the protective sleeve, and also realizes the function of easy connection to the hanging frame;
[0013] (1) By setting up a vertical furnace hanging frame, a protective sleeve mounting bracket and a waterproof protective sleeve, when in use, the product is first fixed at the bottom of the vertical furnace hanging frame. The hanging frame is slowly lowered by a hoisting device, and the product is inserted into the waterproof protective sleeve. After the vertical furnace hanging frame and the protective sleeve mounting bracket are connected, they are lifted at the same time. After being immersed in the quenching water tank, the vertical furnace hanging frame is separated from the right-angle hook. The temperature of the low-temperature quenching liquid is transferred to the product through the waterproof protective sleeve, so that it can complete the quenching. After quenching, the vertical furnace hanging frame is lifted into the vertical quenching furnace. Due to the separation of the hooks between the vertical furnace hanging frame and the protective sleeve mounting bracket, the vertical furnace hanging frame will pull the product out of the waterproof protective sleeve. During this process, the product is isolated from water, which can effectively prevent the product from entering the furnace with water, and realize the function of waterproofing the workpiece.
[0014] (2) By setting concave clips, mounting bolts and pre-drilled screw grooves, the number of waterproof protective sleeves can be increased or decreased according to processing needs during use. The concave clips at the head end of the waterproof protective sleeve are inserted along the inner side of the protective sleeve mounting frame. The screw holes on the concave clips are aligned with the pre-drilled screw grooves on the protective sleeve mounting frame. The installation can be completed by driving in the mounting bolts, thus realizing the function of easy disassembly and assembly of the protective sleeve.
[0015] (3) By setting an external slot, a fixed pin, a connecting plate, a bushing, a counterweight and a right-angle hook, when in use, the vertical furnace hanging frame is placed horizontally on the protective sleeve mounting frame. The connecting plate is pushed towards the protective sleeve mounting frame. As the vertical furnace hanging frame is lifted, the right-angle hook is hung on the protective sleeve mounting frame. When it needs to be disassembled, the vertical furnace hanging frame is lowered. Under the action of the counterweight, the connecting plate tilts backward with the fixed pin as the fulcrum, and the right-angle hook is disengaged from the vertical furnace hanging frame, thus realizing the function of easy connection of the hanging frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Please refer to Figure 1-4 A waterproof protective frame for vertical quenching includes a vertical furnace hanging frame 1, a protective sleeve mounting frame 2 is provided below the vertical furnace hanging frame 1, multiple sets of waterproof protective sleeves 3 are provided inside the protective sleeve mounting frame 2, a concave clip 4 is fixedly connected to the outer side of the waterproof protective sleeve 3, two sets of mounting bolts 5 are inserted into the top of the concave clip 4, multiple sets of pre-cut screw grooves 6 are opened at the top of the protective sleeve mounting frame 2, and a right angle hook 12 is welded to the top of the inner side of the connecting plate 9.
[0023] The vertical center lines of the vertical furnace hanging frame 1 and the protective sleeve mounting bracket 2 coincide, and there is a distance between the vertical furnace hanging frame 1 and the protective sleeve mounting bracket 2. The bottom of the waterproof protective sleeve 3 is closed, and the top of the waterproof protective sleeve 3 is open. Waterproofing can prevent problems such as damage to the furnace body.
[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the product is first fixed to the bottom of the vertical furnace hanging frame 1. The hanging frame is slowly lowered by a hoisting device, and the product is inserted into the waterproof protective sleeve 3. After the vertical furnace hanging frame 1 and the protective sleeve mounting bracket 2 are connected, they are lifted at the same time. After being immersed in the quenching water tank, the vertical furnace hanging frame 1 is separated from the right-angle hook 12. The temperature of the low-temperature quenching liquid is transferred to the product through the waterproof protective sleeve 3, so that it can complete the quenching. After quenching, the vertical furnace hanging frame 1 is lifted into the vertical quenching furnace. Since the hooks between the vertical furnace hanging frame 1 and the protective sleeve mounting bracket 2 are separated, the vertical furnace hanging frame 1 will pull the product out of the waterproof protective sleeve 3. During this process, the product is isolated from water, which can effectively prevent the product from bringing water into the furnace.
[0025] The shape and size of the concave clip 4 are compatible with the shape and size of the protective sleeve mounting bracket 2. The mounting bolt 5 passes through the concave clip 4 and extends into the interior of the pre-cut screw groove 6. The position and size of the mounting bolt 5 and the pre-cut screw groove 6 are corresponding. The external thread of the mounting bolt 5 matches the internal thread of the pre-cut screw groove 6, which facilitates the installation and removal of the waterproof sleeve.
[0026] Specifically, such as Figure 1 and Figure 3 As shown, insert the concave clip 4 at the end of the waterproof protective sleeve 3 along the inner side of the protective sleeve mounting bracket 2, align the screw hole on the concave clip 4 with the pre-cut screw groove 6 on the protective sleeve mounting bracket 2, and then drive in the mounting bolt 5 to complete the installation.
[0027] The outer side of the vertical furnace hanging frame 1 has four sets of external slots 7. The inside of the external slots 7 is fixedly connected with a fixing pin 8. The inside of the external slots 7 is vertically arranged with a connecting plate 9. The bottom of the outer side of the connecting plate 9 is bolted to a bushing 10. The top of the outer side of the connecting plate 9 is welded with a counterweight 11. The fixing pin 8 passes through the inside of the bushing 10. The outer diameter of the fixing pin 8 is smaller than the inner diameter of the bushing 10, which facilitates hooking and unhooking.
[0028] Specifically, such as Figure 3 and Figure 4 As shown, the vertical furnace hanging frame 1 is placed horizontally on the protective sleeve mounting bracket 2. The connecting plate 9 is pushed towards the protective sleeve mounting bracket 2. As the vertical furnace hanging frame 1 is lifted, the right-angle hook 12 is hooked on the protective sleeve mounting bracket 2. When it needs to be disassembled, the vertical furnace hanging frame 1 is lowered. Under the action of the counterweight block 11, the connecting plate 9 tilts backward with the fixed pin 8 as the fulcrum, and the right-angle hook 12 is disengaged from the vertical furnace hanging frame 1.
[0029] Working Principle: In use, the product is first fixed to the bottom of the vertical furnace hanging frame 1. The frame is slowly lowered using a hoisting device, and the product is inserted into the waterproof protective sleeve 3. The vertical furnace hanging frame 1 and the protective sleeve mounting bracket 2 are then connected and simultaneously lifted. After immersion in the quenching water tank, the vertical furnace hanging frame 1 detaches from the right-angle hook 12. The temperature of the low-temperature quenching liquid is transferred to the product through the waterproof protective sleeve 3, completing the quenching process. After quenching, the vertical furnace hanging frame 1 is lifted into the vertical quenching furnace. Due to the separation of the hooks between the vertical furnace hanging frame 1 and the protective sleeve mounting bracket 2, the vertical furnace hanging frame 1 pulls the product out of the waterproof protective sleeve 3. During this process, the product is isolated from water, effectively preventing water from entering the furnace. The number of waterproof protective sleeves 3 can be increased or decreased according to processing needs. The concave clip 4 at the head of the waterproof protective sleeve 3 is inserted along the inner side of the protective sleeve mounting bracket 2. The screw holes on the concave clip 4 are aligned with the pre-drilled screw grooves 6 on the protective sleeve mounting bracket 2, and the installation bolts 5 are driven in to complete the installation. The vertical furnace hanging frame 1 is placed horizontally on the protective sleeve mounting bracket 2. The connecting plate 9 is pushed towards the protective sleeve mounting bracket 2. As the vertical furnace hanging frame 1 is lifted, the right-angle hook 12 is hooked on the protective sleeve mounting bracket 2. When it needs to be disassembled, the vertical furnace hanging frame 1 is lowered. Under the action of the counterweight 11, the connecting plate 9 tilts backward with the fixed pin 8 as the fulcrum, and the right-angle hook 12 is disengaged from the vertical furnace hanging frame 1.
