Description

Technical Field

[0001] This utility model relates to the field of quenching technology, and in particular to a quenching device for metal casting processing. Background Technology

[0002] Quenching of metal castings is an important heat treatment process aimed at improving the hardness, strength, wear resistance, and fatigue life of castings. There are two main types of quenching methods for metal castings: immersion quenching and spray quenching. Spray quenching offers the advantage of rapid cooling and is suitable for workpieces requiring high-hardness surfaces.

[0003] In spray quenching of metal castings, rollers are used to transport the castings. As the castings pass through the spray structure, they undergo spray quenching. However, existing spray quenching devices only use the upper spray components to spray the castings, leaving the lower part of the casting without a spray structure. This results in uneven quenching from top to bottom, affecting the uniform cooling of the castings. Furthermore, when using rollers to transport castings, there is no way to provide spray cooling protection for the rollers. The rollers are prone to damage after prolonged contact with the high-temperature castings, thus increasing operating costs. Utility Model Content

[0004] The main objective of this invention is to provide a quenching device for metal casting processing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a quenching device for metal casting processing includes a conveyor frame 1, a conveyor roller 2 on the inner side of the conveyor frame 1, a collection box 3 below the conveyor frame 1, a bracket 4 fixed to the upper end of the conveyor frame 1, a top plate 5 on the bracket 4, a spray assembly 6 on the bracket 4, insertion holes on the conveyor frame 1, and a spray structure 7 installed on the inner side of the conveyor frame 1. A reduction motor 8 is fixed to the end of the conveyor frame 1, and a support leg 9 is provided at the lower end of the conveyor frame 1.

[0019] When using a quenching device to quench metal castings, the conveyor frame 1 is placed on support legs 9 and connected to relevant pipes. After starting the reduction motor 8, all conveyor rollers 2 rotate synchronously under the drive of the sprockets and chains at the ends of the conveyor rollers 2, placing the metal castings onto them. The conveyor rollers 2 move with the metal castings. Simultaneously, water from the water source enters the middle of the spray assembly 6 at the support 4 and top plate 5. When the metal castings move to the spray assembly 6, the spray assembly 6 sprays water to quench the metal castings. During the quenching process, the spray structure 7 sprays atomized water vapor onto the conveyor rollers 2 in front of the support 4, cooling these rollers and extending their service life, thus reducing operating costs. The water droplets from the spray fall into the recycling bin 3 for collection, preventing waste.

[0020] According to the above implementation scheme, the spray assembly 6 includes an arc-shaped pipe 601, a spray head 602, a connecting rod 603, a mounting plate 604, and a water injection pipe 605. The spray head 602 is disposed on the arc-shaped pipe 601, and the arc-shaped pipe 601 is fixedly connected to the connecting rod 603. The mounting plate 604 is installed at the end of the connecting rod 603, and the mounting plate 604 is fixed to the bracket 4 by screws. The water injection pipe 605 is disposed at the upper end of the arc-shaped pipe 601, and the water injection pipe 605 penetrates through the top plate 5.

[0021] When installing the spray assembly 6, it is fixed in place by using the mounting plate 604 at the end of the connecting rod 603 with screws. The spray heads 602 are arranged in a ring array. The water injection pipe 605 passes through the top plate 5 and is connected to the pipeline for use. During use, water from the water source enters the water injection pipe 605 and is then sprayed out from the spray heads 602 on the arc-shaped pipe 601. Because the spray heads 602 are arranged in a ring array, the sprayed water can act evenly on the metal casting, ensuring the uniformity of quenching.

[0022] According to the above implementation scheme, the spray structure 7 includes a horizontal pipe 701, an atomizing nozzle 702 and a mounting assembly 703. The atomizing nozzle 702 is evenly distributed on the horizontal pipe 701, and the two mounting assemblies 703 are set at both ends of the horizontal pipe 701, and the mounting assemblies 703 are connected to the insertion holes on the conveyor frame 1.

[0023] When installing the spray structure 7, the horizontal pipe 701 is set below the corresponding conveying roller 2 by the installation component 703, and the atomizing nozzle 702 faces the conveying roller 2. When conveying metal castings, water from the water source enters the horizontal pipe 701 and is finally sprayed out from the atomizing nozzle 702. The sprayed atomized water acts on the conveying roller 2 to cool it down, preventing the conveying roller 2 from being damaged by heat for a long time and ensuring the effect of use.

[0024] The mounting assembly 703 includes a connector 7031, a clamping screw 7032, a hexagonal rod 7033, a baffle 7034, a spring 7035, a plug 7036, and a limiting plate 7037. The connector 7031 is sleeved on the horizontal tube 701. The clamping screw 7032 is threaded onto the connector 7031. The hexagonal rod 7033 is fixedly connected to the baffle 7034 and passes through the connector 7031. The spring 7035 is sleeved on the hexagonal rod 7033, and the ends of the spring 7035 contact the connector 7031 and the baffle 7034 respectively. The plug 7036 is mounted on the baffle 7034. The limiting plate 7037 is located at the end of the hexagonal rod 7033.

[0025] When installing the horizontal tube 701, first place the connecting seat 7031 onto the horizontal tube 701 and secure it with the locking screw 7032. Then, move the baffle 7034 and the plug 7036 to make room, allowing the hexagonal rod 7033 to move along the connecting seat 7031, compressing the spring 7035. Next, place the entire spray structure 7 inside the conveyor frame 1, ensuring that the plug 7036 aligns with the socket. After releasing the baffle 7034, under the action of the spring 7035, the hexagonal rod 7033 moves along the connecting seat 7031, connecting the plug 7036 on the baffle 7034 into the socket until the baffle 7034 contacts the conveyor frame 1. During use, the entire spray structure 7 has good stability due to the action of the spring 7035. When disassembly is required, simply move the baffle 7034 to compress the spring 7035 and pull out the plug 7036 from the socket. The structure is simple and the operation is convenient and quick.

[0026] It should be noted that the spray assembly 6, with spray heads 602 installed on the two arc-shaped pipes 601, allows all the spray heads 602 to be distributed in a ring array, which can uniformly spray the casting for quenching, resulting in high uniformity of quenching and ensuring the quenching effect. A spray structure 7 is installed below the conveyor rollers 2 in front of the bracket 4. The spray structure 7 is used to spray and cool the corresponding conveyor rollers 2, preventing them from being damaged by heat for a long time and extending their service life. The horizontal pipe 701 is installed on the conveyor frame 1 using the mounting assembly 703. It adopts a structure with hexagonal rod 7033, spring 7035, and plug 7036. Moving the hexagonal rod 7033 can quickly move the plug 7036 to make way, facilitating quick installation and disassembly. The spring 7035 provides a clamping force to ensure that the entire spray structure 7 has good stability after installation.

[0027] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
