Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, specifically a spring hot rolling machine. Background Technology

[0002] Hot coiling of springs refers to the process of winding heated metal materials into springs using a hot coiling spring machine. A hot coiling spring machine is a specialized piece of equipment for producing springs. Its working principle involves guiding heated metal materials through a guide assembly to a hot coiling assembly, where hot coiling rollers then wind the material into a spring shape. Because metal materials have good plasticity and ductility when heated, springs of various shapes and specifications can be manufactured through hot coiling. The advantages of hot coiling springs include the ability to produce larger springs with high precision in shape and size.

[0003] CN222830590U discloses a spring hot-rolling machine, relating to the field of spring processing technology. It includes a cylinder unloading component, a gear motor component, gears, and a fixing plate. A molding fixing seat is provided on the front of the fixing plate. A positive and negative lead screw is provided inside the molding fixing seat, and a rotating feeding component fixing seat is provided on the outside of the molding fixing seat. Two movable blocks are symmetrically arranged on the positive and negative lead screws. A rotating feeding component is provided inside the rotating feeding component fixing seat, and a driving component is provided on one side of the rotating feeding component fixing seat. Multiple movable rods are radially and evenly spaced on the movable blocks. An arc-shaped molding plate is provided at the other end of each movable rod. A molding groove is rotatably provided on the outside of the arc-shaped molding plate around its axis. With the above structure, this utility model can quickly perform spring hot-rolling processing, is simple to operate, and can effectively improve work efficiency.

[0004] During the use of this spring hot rolling machine, it was found that while the spring material was being hot rolled, the deformation caused by the winding prevented the outer cooling layer from deforming synchronously, resulting in a large number of fragments falling off the surface of the spring material. These fragments easily entered the interior of the curved molding plate 12 or the operating table, requiring subsequent cleaning and affecting the efficiency of the hot rolling. Therefore, it is necessary to design a spring hot rolling machine to improve the above problems. Utility Model Content

[0028] In the following description, embodiments of the spring hot rolling machine of this utility model will be described with reference to the accompanying drawings.

[0029] Figure 1-4 This invention illustrates an embodiment of a spring hot-rolling machine, which includes:

[0030] A support plate 2 is fixedly installed on the top of the base plate 1. A rotating table 3 is rotatably connected to the rear side of the support plate 2. A hot-rolled column 4 is fixedly installed on the rear side of the rotating table 3.

[0031] It also includes locking blocks 5 and 9. Locking block 5 slides on the rear side of the rotating table 3, and 9 is wound around the surface of the hot rolling column 4. Locking block 5 limits one end of 9. By setting locking block 5, when the size of 9 changes, locking block 5 can be slid to adjust the distance between locking block 5 and hot rolling column 4, so as to meet the clamping and limiting of 9 of different sizes, thereby improving the practicality of the hot rolling machine. Specifically, a sliding groove 31 is provided on the rear side of the rotating table 3. The inner cavity of the sliding groove 31 is rotatably connected to a threaded rotating rod 32 extending to the outside. The front end of locking block 5 extends into the inner cavity of the sliding groove 31 and is threadedly connected to the surface of the threaded rotating rod 32.

[0032] The base plate 1 has a traction roller 6 slidably connected to its top. The traction roller 6 has a groove on its surface that cooperates with the hot-rolling column 4. The traction roller 6 slides back and forth at the bottom of the hot-rolling column 4. Specifically, a sliding table 61 is slidably connected to the top of the base plate 1. A telescopic limiting rod 62 is fixedly installed on the top of the sliding table 61. The traction roller 6 is fixedly installed on the top of the telescopic limiting rod 62. The waste hopper assembly 7 is detachably installed on the top of the sliding table 61. By using the telescopic limiting rod 62, the distance between the traction roller 6 and the hot-rolling column 4 can be adjusted when hot-rolling different sizes of 9, thus achieving the desired guiding effect for 9 of different sizes. Specifically, the base plate 1 has a... Guide rod 64, sliding table 61 slides on the surface of guide rod 64, threaded rod 63 is rotatably connected to the top of base plate 1, sliding table 61 is threadedly connected to the surface of threaded rod 63, waste hopper assembly 7 is installed at the bottom of traction roller 6, waste hopper assembly 7 moves with traction roller 6. Specifically, waste hopper assembly 7 is composed of clamping hopper one 71 and clamping hopper two 72. Clamping hopper one 71 and clamping hopper two 72 are detachably installed by L-shaped clamping block 73. L-shaped clamping block 73 is fixedly installed on the surface of clamping hopper one 71. Telescopic limit rod 62 is clamped between clamping hopper one 71 and clamping hopper two 72. The waste hopper assembly 7 is made of heat-resistant material to avoid damage caused by residual heat on falling fragments.

[0033] Specifically, a telescopic roller assembly 8 is provided at the rear end of the top of the base plate 1. The telescopic roller assembly 8 lifts the rear end of the hot-rolled column 4. Specifically, the telescopic roller assembly 8 includes a lifting platform 81 that slides up and down on the top of the base plate 1. Multiple rollers 82 that cooperate with the hot-rolled column 4 are fixedly installed on the top of the lifting platform 81. The rollers 82 roll on the surface of the hot-rolled column 4. The lifting platform 81 is installed on the top of the base plate 1 through a double-layer scissor lifting device 83. By setting the telescopic roller assembly 8, the rear end of the hot-rolled column 4 can be lifted during the hot-rolling operation, thereby improving the stability of the hot-rolled column 4 when rotating. When the spring needs to be unloaded after the hot-rolling is completed, it can be retracted to make it fall off the surface of the hot-rolled column 4, which facilitates the unloading operation of the spring. The structure of the double-layer scissor lifting device 83 can be referred to the attached drawings or existing technology.

[0034] Working principle: When using this utility model, the user pulls one end of 9 into the groove in the traction roller 6, positioning it at the bottom of the front side of the hot winding column 4. Then, rotating the threaded rotating rod 32 causes the locking block 5 to slide towards the hot winding column 4 within the inner cavity of the sliding groove 31, thereby clamping and limiting 9. Subsequently, rotating the rotating table 3 causes the hot winding column 4 to rotate, and simultaneously controlling the threaded rod 63 to rotate, thereby causing the sliding table 61 to slide backward on the surface of the guide rod 64. This, in turn, causes the waste hopper assembly 7, the telescopic limiting rod 62, and the traction roller 6 to slide backward at a uniform speed, so that 9 is evenly wound around the hot winding column. At this time, due to the winding, the fragments on the surface of column 4 fall off and fall into the waste hopper assembly 7 for collection. After the winding is completed, the lifting platform 81 is moved down by the double-layer scissor lifting device 83, so that the roller 82 falls off the surface of the hot-rolled column 4. Then, the material on the surface of the hot-rolled column 4 is dematerialized. At the same time, the clamping bucket 1 71 is pulled up, which causes the L-shaped card block 73 to disengage from the surface of the clamping bucket 2 72 and release the limiting lock on clamping bucket 1 71 and clamping bucket 2 72. This makes it easier for the user to collect the waste in the waste hopper assembly 7, avoid waste and improve the efficiency of hot rolling.

[0035] In summary, this spring hot rolling machine uses the sliding of the traction roller 6 in conjunction with the rotation of the hot rolling column 4 to wind 9 onto the surface of the hot rolling column 4. At this time, the fragments that fall off the surface of 9 will fall into the waste hopper assembly 7 for collection and centralized recycling, thus avoiding waste and improving the efficiency of hot rolling.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
