Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, and more specifically, to an annealing device for processing mattress springs. Background Art

[0002] Mattress springs are springs used in mattresses. Mattress springs wound by cold coiling process generally use lead bath isothermal quenching and cold drawn steel wires (carbon spring steel wires, piano wires) and oil quenched and tempered spring steel wires. Mattress springs cold coiled with these steel wires do not require quenching treatment, but the mattress springs must be put into an annealing device for stress relief annealing.

[0003] When annealing mattress springs, the springs need to be heated to an appropriate temperature and maintained for a period of time, and then slowly cooled to achieve the purpose of eliminating the internal stress of the mattress springs. When the existing annealing device is in use, the internal storage device is usually set as a large frame, so that the mattress springs at the bottom of the storage device are prone to deformation after annealing and heating, resulting in a reduction in the yield rate of the mattress springs.

[0004] In view of this, we propose an annealing device for processing mattress springs. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide an annealing device for processing mattress springs to solve the technical problem that the springs piled up at the bottom of the storage device are prone to deformation when the current mattress springs are annealed.

[0006] To solve the above technical problems, the utility model provides the following technical solutions: An annealing device for processing mattress springs, including an annealing furnace and a storage mechanism placed inside the annealing furnace. The storage mechanism includes a support plate. One side of the top of the support plate is installed with a guiding slide rail, and the other side of the top of the support plate is installed with a directional slide rail. A plurality of storage boxes are jointly slidably supported by the guiding slide rail and the directional slide rail;

[0007] A plurality of the storage boxes are connected by a buckle device. The buckle device includes a fixing plate and a positioning plate, and the fixing plate and the positioning plate are fitted and connected;

[0008] Preferably, a connecting plate is installed inside the fixing plate. One end of the connecting plate is rotatably connected to the fixing plate, and the other end of the connecting plate extends above the positioning plate.

[0009] Preferably, an arc block is constructed at the bottom of the end of the connecting plate extending above the positioning plate. A groove for the arc block to be fitted is opened at the top of the positioning plate, and a gap for easily pushing the arc block upward is opened between the top of the positioning plate and the low end of the connecting plate.

[0010] Preferably, a guiding tube is installed on one side of the storage box. The guiding tube is placed above the directional slide rail. A guiding column is slidably installed in the guiding tube, and a limiting rod is slidably installed in the storage box.

[0011] Preferably, one end of the guiding column extends into the storage box and is installed with a roller. The roller is connected to the guiding column through a short rod.

[0012] Preferably, a slot for the limiting rod to slide up and down is opened in the storage box. A limiting column is constructed at the bottom end of the limiting rod. A plurality of slots for the limiting column to be inserted are equidistantly arranged in an array on the directional slide rail. An arc slot facing the roller is opened on the side of the limiting rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the fixed plate and the positioning plate designed between the two storage boxes of the present utility model, the arc block at one end of the connecting plate rotatably installed in the fixed plate is inserted into the slot opened at the top end of the positioning plate. When connecting the two storage boxes, through the gap opened on the positioning plate, the positioning plate can fit the arc surface of the arc block, rotate and lift the connecting plate, and complete the fixation of the two storage boxes by fitting the arc block into the positioning plate. By pulling the connecting plate, the fixation of the two storage boxes can be quickly released. By setting it as multiple storage frames to prevent replacing a larger storage frame, while improving the spring annealing effect, it can avoid the phenomenon that the mattress springs accumulate at the bottom and deform.

[0015] 2. The present utility model also designs a limiting rod in the storage box. The limiting column at the bottom end of the limiting rod is inserted into the slot opened on the directional slide rail to complete the fixation of the storage box. During disassembly, press the guiding column in the guiding tube. The roller installed on the guiding column fits the arc slot opened on the side of the limiting rod. By the movable roller abutting against the arc surface of the guiding column, while lifting the limiting rod, the friction force can be reduced, which is convenient for quick fixation and can shorten the interval time of batch annealing of mattress springs.

[0025] As Figures 1 to 7 shown, the present utility model relates to an annealing device for processing mattress springs, including an annealing furnace 1 and a storage mechanism 2 placed inside the annealing furnace 1. The storage mechanism 2 includes a support plate 201. One side of the top of the support plate 201 is provided with a guide slide rail 202, and the other side of the top of the support plate 201 is provided with a directional slide rail 203. The guide slide rail 202 and the directional slide rail 203 jointly slide and support a plurality of storage boxes 3;

[0026] A plurality of storage boxes 3 are connected by a buckle device. The buckle device includes a fixing plate 4 and a positioning plate 5. The fixing plate 4 and the positioning plate 5 are fitted and connected. A connecting plate 401 is installed inside the fixing plate 4. One end of the connecting plate 401 is rotatably connected to the fixing plate 4, and the other end of the connecting plate 401 extends above the positioning plate 5. An arc block 402 is formed at the bottom of the end of the connecting plate 401 extending above the positioning plate 5. A groove for the arc block 402 to be fitted into is opened at the top end of the positioning plate 5. A gap 501 for easily pushing the arc block 402 upward is opened between the top end of the positioning plate 5 and the low end of the connecting plate 401. By designing the fixing plate 4 and the positioning plate 5 between two storage boxes 3, the arc block 402 at one end of the connecting plate 401 rotatably installed inside the fixing plate 4 is inserted into the groove opened at the top end of the positioning plate 5. When connecting two storage boxes 3, through the gap 501 opened on the positioning plate 5, the positioning plate 5 can be made to fit the arc surface of the arc block 402, rotate and lift the connecting plate 401, and the arc block 402 is fitted into the positioning plate 5 to complete the fixation of the two storage boxes 3. By pulling the connecting plate 401, the fixation of the two storage boxes 3 can be quickly released. By setting it as a plurality of storage frames to prevent replacing a larger storage frame, the spring annealing effect can be improved while avoiding the phenomenon of deformation caused by the accumulation of mattress springs at the bottom; through the limiting rod 7 designed inside the storage box 3, the limiting column at the bottom of the limiting rod 7 is inserted into the groove opened on the directional slide rail 203 to complete the fixation of the storage box 3. When disassembling, press the guide post 601 inside the guide tube 6, and the roller 602 installed on the guide post 601 fits the arc groove 701 opened on the side of the limiting rod 7. By the movable roller 602 abutting against the arc surface of the guide post 601, the limiting rod 7 can be lifted while reducing the friction force, which is convenient for quick fixation and can shorten the batch of mattress springs

[0027] Working principle: This embodiment provides an annealing device for processing mattress springs. When in use, the slider at the bottom of the storage box 3 is installed on the guiding slide rail 202 and the directional slide rail 203. When pushing the storage box 3, the guiding column 601 is pressed, and the roller 602 at one end of the guiding column 601 abuts against the arc surface of the arc groove 701, so that the limiting rod 7 rises upward, and the limiting column at the bottom of the limiting rod 7 is pulled out from the groove opened at the top of the directional slide rail 203, facilitating the pushing of the storage box 3. When connecting multiple storage boxes 3, by the positioning plate 5 abutting against the arc block 402 on the pushing connecting plate 401, the connecting plate 401 rotates upward. Continuing to push the storage box 3, after the arc block 402 at the bottom of the connecting plate 401 is fitted into the groove opened at the top of the positioning plate 5, the connection between multiple storage boxes 3 is completed. Then, the annealing furnace 1 is closed for annealing treatment. After annealing, the arc groove 701 at the bottom of the limiting rod 7 is pulled out from the directional slide rail 203 by pressing the guiding column 601, releasing the fixation between the directional slide rail 203 and the storage box 3. After that, the storage box 3 is pulled out. When the outermost storage box 3 is pulled out, the connection between adjacent storage boxes 3 can be automatically released, which is convenient for taking out the mattress springs and can also avoid the phenomenon of mattress spring deformation caused by excessive accumulation.
