Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically to a shock-absorbing loading frame for heat treatment of castings. Background Technology

[0002] The casting heat treatment loading rack is a specialized tooling equipment used to support, position, and protect castings throughout the entire heat treatment process (such as annealing, normalizing, quenching, solution treatment, etc.). Its core function is to ensure that castings can stably complete heat treatment under complex conditions such as high temperature and temperature rise and fall, while reducing deformation and damage, and improving process efficiency and casting quality. It needs to be directly placed into the heat treatment furnace along with the castings (or used in conjunction with the external conveying process), and is a key auxiliary device connecting the castings and the heat treatment process.

[0003] Existing casting heat treatment loading racks pose a risk of deformation or damage to castings when they are displaced due to thermal expansion and contraction or external vibration during the heat treatment process. Therefore, a casting heat treatment shock-absorbing loading rack is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing loading rack for heat treatment of castings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A shock-absorbing loading rack for heat treatment of castings includes a storage plate. A first support ring is fixedly connected to the bottom end of the storage plate. A damping rod is fixedly connected to the bottom end of the first support ring. A second support ring is fixedly connected to the bottom end of the damping rod. A damping spring located outside the damping rod is fixedly connected between the first and second support rings. A fixing ring is fixedly connected to the outside of the second support ring. A high-temperature resistant rubber ring is fixedly connected to the bottom end of the fixing ring. Bolts are threadedly connected to the fixing ring and the high-temperature resistant rubber ring. A sliding groove is formed inside the storage plate. A limiting groove is symmetrically arranged on both sides of the sliding groove. A limiting block is slidably connected inside the limiting groove. An extension strip located inside the sliding groove is fixedly connected between the two limiting blocks. A positioning hole is formed at the top end of the extension strip. A positioning rod is provided inside the positioning hole. A storage ring is fixedly connected to the top end of the positioning rod. A support rod is fixedly connected to the inner side of the second support ring.

[0006] Preferably, there are several positioning holes, which are evenly spaced at the top of the extension strip.

[0007] Preferably, the positioning holes and positioning rods are a set, and there are several sets in total. The positioning holes and positioning rods are evenly arranged on the outer side of the shelf with the center of the shelf as the center. A shelf ring is fixedly connected to the top of multiple positioning rods at the same distance around the outer side of the shelf.

[0008] Preferably, the storage ring and the six positioning rods are grouped together, and there are several groups in total. The diameter of each group of the storage ring and the six positioning rods is larger than that of the previous group, and the spacing size matches that of the positioning holes.

[0009] Preferably, the inner shape of the chute and the limiting groove matches the size of the extension strip and the limiting block combined together, and the inner width of the chute and the limiting groove matches the width of the extension strip and the limiting block combined together.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting up components such as a first support ring, a damping rod, a second support ring, a vibration damping spring, a fixing ring, a high-temperature resistant rubber ring, bolts, and a support rod, when the casting is displaced due to thermal expansion and contraction during heat treatment or external vibration, the elastic element damping rod, vibration damping spring, and high-temperature resistant rubber ring can absorb the energy of the impact, reduce the impact force on the casting, and prevent its deformation or damage. At the same time, the reinforcement structure can fix the entire loading frame to prevent displacement and shaking when impacted, thereby solving the problem of deformation or damage to the casting when it is displaced due to thermal expansion and contraction or external vibration during heat treatment in existing casting heat treatment loading frames. 2. In this utility model, by setting components such as sliding grooves, limiting grooves, limiting blocks, extension strips, positioning holes, and storage rings, the support range of the storage plate can be expanded, and it can support castings of various sizes. In particular, for thinner plate-shaped castings, multi-point support can be adopted. For example, a replaceable storage ring can be set on the storage plate to achieve contact support for thick parts of the casting, so as to avoid deformation or cracking of the casting after heating.

[0016] Please see Figure 1-4 This utility model provides a technical solution: A shock-absorbing loading rack for heat treatment of castings includes a storage plate 1. A first support ring 2 is fixedly connected to the bottom end of the storage plate 1. A damping rod 3 is fixedly connected to the bottom end of the first support ring 2. A second support ring 4 is fixedly connected to the bottom end of the damping rod 3. A damping spring 5 located outside the damping rod 3 is fixedly connected between the first support ring 2 and the second support ring 4. A fixing ring 6 is fixedly connected to the outside of the second support ring 4. A high-temperature resistant rubber ring 7 is fixedly connected to the bottom end of the fixing ring 6. The fixing ring 6 and the high-temperature resistant rubber ring 7 have internal threads. The shelf 1 is connected by bolts 8. The shelf 1 has a sliding groove 9 inside. The shelf 1 has a limiting groove 10 symmetrically arranged on both sides of the sliding groove 9 inside. The limiting groove 10 is slidably connected to the limiting block 11. An extension strip 12 located inside the sliding groove 9 is fixedly connected between the two limiting blocks 11. The top of the extension strip 12 has a positioning hole 13. The positioning hole 13 has a positioning rod 14 inside. The top of the positioning rod 14 is fixedly connected to a shelf ring 15. The inner side of the second support ring 4 is fixedly connected to a support rod 16.

[0017] The number of positioning holes 13 is several, and the positioning holes 13 are evenly arranged at intervals on the top of the extension strip 12, which can accommodate castings of multiple sizes and furnaces. The positioning holes 13 and positioning rods 14 are grouped together, and there are several groups in total. The positioning holes 13 and positioning rods 14 are evenly arranged on the outer side of the shelf 1 with the center of the shelf 1 as the center. The top of the multiple positioning rods 14 at the same distance on the outer side of the shelf 1 is fixedly connected to a shelf ring 15, which facilitates the simultaneous fixing of multiple groups of extended extension strips 12, providing more stable support for the casting, improving ventilation, and facilitating The casting is heated; the placement ring 15 and the six positioning rods 14 are grouped together, and there are several groups in total. The diameter of each group of placement ring 15 and the six positioning rods 14 is larger than that of the previous group, and the spacing size matches the positioning hole 13, which facilitates the fixing of replacement placement rings 15 of different sizes; the inner shape of the slide groove 9 and the limiting groove 10 matches the size of the extension strip 12 and the limiting block 11 combined together, and the inner width of the slide groove 9 and the limiting groove 10 matches the width of the extension strip 12 and the limiting block 11 combined together, so that the extension strip 12 moves more smoothly and avoids the extension strip 12 from shaking.

[0018] Workflow: When a shock-absorbing loading rack for casting heat treatment is required, it is first fixed inside the furnace using bolts 8 and retaining rings 6. After fixing, multiple extension strips 12 can be pulled and moved under the guidance of slide grooves 9, limiting grooves 10, and limiting blocks 11, according to the dimensions of the furnace and the casting. This allows multiple sets of extension strips 12 to move synchronously and the same distance until the diameter of the combined placement plate 1 and extension strips 12 is greater than the maximum size of the casting. Then, a placement ring 15 matching the dimensions shown in the figure is inserted into the positioning hole 13 under the action of the positioning rod 14. Simultaneously, the placement ring 15... The position of the extension strip 12 is fixed to accommodate furnaces and castings of various sizes. The casting can then be placed on the surface of the storage ring 15 and the storage plate 1 for support. The damping rod 3, vibration damping spring 5, and high-temperature resistant rubber ring 7 can effectively absorb the vibration caused by the thermal expansion and contraction of the casting. The second support ring 4, fixing ring 6, and bolt 8 can prevent the impact of the casting on the storage ring 15 and the storage plate 1 at the moment of contact, which could cause the overall loading frame to shift. The support rod 16 can effectively strengthen the rigidity of the second support ring 4 and prevent the loading frame from deforming.
