Description

Technical Field

[0001] This utility model belongs to the technical field of compression and shaping devices, specifically relating to a compression and shaping device for springs before heat treatment. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Parts made of elastic materials deform under external force and return to their original shape after the force is removed. Heat treatment of springs involves heating, holding, and cooling the spring to change the internal structure of the metal and alloy, thereby altering the mechanical, physical, and chemical properties of the material. Before heat treatment, springs need to undergo compression shaping to ensure that the heat-treated springs meet product quality requirements. This process requires the use of compression shaping equipment.

[0003] In the operation of compression shaping devices, springs are fitted onto positioning rods, and hydraulic devices are used to push pressure plates to compress and shape the springs. However, in existing compression shaping devices, the size of the positioning rod used to limit the springs is fixed. When compressing and shaping springs with large size differences, this can easily lead to significant spring displacement, affecting the quality of subsequent processing. Therefore, there is an urgent need for a compression shaping device for springs before heat treatment.

[0004] A patent with publication number CN222740164U discloses a compression and shaping device for springs before heat treatment. The device includes a threaded tube, a movable plate, a push plate, a telescopic plate, sleeve rods, a movable hole, a hydraulic cylinder, an extrusion plate, and a support plate. In use, rotating the threaded tube moves the movable plate laterally. Through the transmission and limiting action of the push plate and the telescopic plate, multiple sleeve rods slide within the movable hole, allowing the distance between them to be adjusted and ensuring stable placement of the spring. The spring is then fitted onto the sleeve rods, and the hydraulic cylinder is activated. With the cooperation of the extrusion plate and the support plate, the spring is compressed and shaped.

[0005] The above solution increases the distance between the sleeve rods by adjusting their spacing, thus preventing the springs from interfering with each other and allowing for more stable placement. However, the size of the sleeve rods in this solution is fixed. When dealing with springs of different sizes, the sleeve rods cannot effectively limit the springs' movement. This can cause larger springs to shift significantly during compression and shaping, leading to distortion of the shaped springs, increasing the number of defective products, affecting subsequent processing quality, and resulting in limited practical effectiveness. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model provides a spring compression and shaping device before heat treatment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A compression and shaping device for springs before heat treatment includes a worktable. A support frame is fixedly mounted on the top of the worktable. Two support seats are slidably mounted on the bottom of the support frame, and a driving mechanism is provided to drive the two support seats to slide towards or away from each other. Each support seat has several sets of positioning components on its top, and the positioning components are slidably mounted on the top of the support frame. The number of positioning components on the two support seats is equal and they correspond one-to-one. Each set of positioning components includes two positioning blocks, and the two positioning blocks in the same set of positioning components slide towards or away from each other. The support seat is driven by the two positioning blocks in the positioning component through a transmission component.

[0008] Furthermore, the driving mechanism includes a second lead screw. The bottom of the support frame is both fixedly equipped with a guide rod and rotatably equipped with the second lead screw, which is a bidirectional lead screw. The two support seats correspond one-to-one with the two threaded sections of the second lead screw, and each support seat is threadedly engaged with the corresponding threaded section. Both support seats are slidably engaged with the guide rod. In addition, a motor is fixedly installed on the support frame, and the output shaft of the motor is coaxially and fixedly connected to one end of the second lead screw.

[0009] Furthermore, the positioning component also includes a connecting seat, which is fixedly mounted on the top of the support base. A through groove is opened on the support frame, and the connecting seat is slidably positioned in the through groove. A groove is opened in the connecting seat, and two positioning blocks in the same group of positioning components are slidably positioned in the groove.

[0010] Furthermore, the transmission component includes a first lead screw, which is rotatably disposed in the groove along the vertical direction, and a slider is threadedly connected to the outer surface of the first lead screw; both sides of the two positioning blocks are provided with sliding grooves, and the two ends of the slider are limited and slidably disposed in the two sliding grooves; the bottom of the first lead screw rotatably passes through the support base and is fixedly disposed with a gear, and a rack that meshes with the gear is fixedly disposed on the top of the worktable, and the rack is arranged along the sliding direction of the support base.

[0011] Furthermore, a pressure plate is connected to the top of the support frame via an external hydraulic device, and the pressure plate has through holes for the positioning block to pass through.

[0012] This application has the following beneficial effects: The start-up drive mechanism can not only adjust the distance between the two sets of positioning components to make the spring more stably placed on the support frame, but also adjust the distance between the two positioning blocks within the same set of positioning components. This allows for more effective limiting of springs of different sizes, preventing large spring offsets, reducing the probability of spring distortion, and decreasing the production of defective products, thus improving practicality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: a spring compression and shaping device before heat treatment, including a worktable 1, a support frame 2 fixedly installed on the top of the worktable 1, and two support seats 4 slidably installed at the bottom of the support frame 2, and a driving mechanism for driving the two support seats 4 to slide towards or away from each other.

[0017] The drive mechanism includes a second lead screw 13. A guide rod is fixedly mounted on the bottom of the support frame 2, and the second lead screw 13 is rotatably mounted thereon. The second lead screw 13 is a bidirectional lead screw. Two support seats 4 correspond one-to-one with two threaded sections of the second lead screw 13. Each support seat 4 is threadedly engaged with its corresponding threaded section, and both support seats 4 are slidably engaged with the guide rod. Additionally, a motor 6 is fixedly mounted on the support frame 2, and the output shaft of the motor 6 is coaxially and fixedly connected to one end of the second lead screw 13.

[0018] Each support base 4 has several sets of positioning components on its top. The positioning components are slidably set on the top of the support frame 2. The number of positioning components on the two support bases 4 is equal and corresponds one to one. Each set of positioning components includes two positioning blocks 5. The two positioning blocks 5 in the same set of positioning components slide towards or away from each other. The support base 4 is driven by the two positioning blocks 5 in the positioning components through a transmission component.

[0019] The positioning component also includes a connecting seat 41, which is fixedly mounted on the top of the support seat 4. A through groove 3 is opened on the support frame 2, and the connecting seat 41 is slidably positioned in the through groove 3. A groove 10 is opened in the connecting seat 41, and two positioning blocks 5 in the same group of positioning components are slidably positioned in the groove 10.

[0020] The transmission components include a first lead screw 8, which is rotatably mounted vertically within a groove 10. A slider 11 is threaded onto the outer surface of the first lead screw 8. Slide grooves 12 are provided on the opposing sides of the two positioning blocks 5, and the slider 11 is slidably positioned within the two slide grooves 12 at both ends. The bottom of the first lead screw 8 rotatably passes through a support base 4 and is fixedly mounted with a gear 7. A rack 9, meshing with the gear 7, is fixedly mounted on the top of the worktable 1, and the rack 9 is arranged along the sliding direction of the support base 4.

[0021] In addition, a pressure plate 14 is connected to the top of the support frame 2 via an external hydraulic device. The pressure plate 14 has a through hole for the positioning block 5 to pass through. The external hydraulic device is prior art and will not be described in detail in this application.

[0022] Working principle: When in use, the spring is sleeved on the outer surface of the two positioning blocks 5. The motor 6 is started, and the output shaft of the motor 6 drives the second lead screw 13 to rotate. With the help of the sliding guide rod, the two support seats 4 are moved away from each other, thereby driving the positioning components on the two support seats 4 to move synchronously, so that the corresponding two positioning components are moved away from each other, thereby adjusting the distance between the corresponding two positioning components so that the spring can be placed more stably on the support frame 2.

[0023] Meanwhile, the two support seats 4 moving away from each other will also drive the gear 7 to move synchronously via the first lead screw 8. Through the meshing of the gear 7 and rack 9, the gear 7 will rotate during its movement, thereby causing the slider 11 to rise. This will cause the two positioning blocks 5 within the same positioning assembly to move away from each other, thus providing more effective limiting for springs of different sizes, preventing large spring offsets, reducing the probability of spring distortion, decreasing the production of defective products, and improving practicality. (It should be noted that this application applies to elliptical springs, commonly known as flat springs, which can be applied to flat springs of more sizes.) Finally, the pressure plate 14 is lowered by an external hydraulic device, thereby completing the compression and shaping process.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
