Description

Technical Field

[0001] This utility model relates to the field of automotive leaf spring processing technology, specifically a pre-compression device for automotive leaf spring processing. Background Technology

[0002] Automotive leaf springs are a common suspension system component used to support and connect the vehicle chassis and body. They consist of multiple layers of bent steel plates, installed between the vehicle's wheels and chassis to provide support and shock absorption. During the manufacturing process, the raw steel plates are bent and assembled to form the spring shape. Due to the elasticity of the material, some deformation may occur during processing, resulting in the spring not perfectly matching the design requirements.

[0003] Authorization announcement number CN220880289U discloses a pre-compression device for processing automotive leaf springs. This patented technology, through the cooperation of multiple structures such as positioning blocks, sliders, sliding rods, moving blocks, through slots, limiting slots, limiting blocks, and fixing frames, enables the clamping of automotive leaf springs of different sizes and types without the need for additional mechanical or equipment adjustments. This reduces the conversion and adjustment time during processing and improves the stability of automotive leaf springs during pre-compression. Through the cooperation of multiple structures such as cylinder one, connecting plate, connecting rod, support plate, pre-compression punch, guide post, and buffer spring, it can automatically pre-compress automotive leaf springs, which helps to improve production efficiency and ensure spring quality and performance. However, this solution cannot easily push and collect the processed leaf springs, which can lead to production interruptions. Workers spend a lot of time pushing and collecting leaf springs. This time could have been used for other production activities, but it is wasted due to the inconvenience of pushing and collecting. If the processing of leaf springs is inconvenient to push and collect, it is difficult to achieve seamless connection between automated equipment. This prevents the automated production line from fully utilizing its advantages and may even require manual intervention, reducing the efficiency and stability of automated production. Therefore, a pre-compression device for processing automotive leaf springs is needed to improve the above problems. Utility Model Content

[0004] To address the problem in the current solution where the processed leaf springs cannot be easily pushed and collected, leading to production interruptions and significant time wasted by workers during this process—time that could have been used for other production activities—and to solve the problems mentioned in the background section, this invention aims to provide a pre-loading device for processing automotive leaf springs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A preloading device for processing automotive leaf springs includes a main body, a pushing assembly fixedly connected to the top of the main body, and a collecting assembly provided on the side of the main body.

[0007] The pushing assembly includes a support plate, and a push rod is installed inside the support plate. The output end of the push rod is fixedly connected to the push plate.

[0008] The collection component includes a collection box, a handle is provided on the side of the collection box, and four casters are provided on the bottom of the collection box.

[0009] As a preferred embodiment of this utility model, the main body includes a base plate, a support frame is fixedly connected to the top of the base plate, and a processing placement plate is fixedly connected to the top of the support frame.

[0010] As a preferred embodiment of this utility model, a protective plate is fixedly connected to the top of the support frame, and two protective plates are provided. A reinforcing angle aluminum is fixedly connected inside the support frame.

[0011] As a preferred embodiment of this utility model, the bottom of the base plate is fixedly connected with an anti-slip pad, and four anti-slip pads are provided.

[0012] As a preferred embodiment of this utility model, the side of the support frame is provided with operation buttons, and there are two operation buttons.

[0013] As a preferred embodiment of this utility model, a vertical rod is fixedly connected to the top of the base plate, and a connecting plate is fixedly connected to the top of the vertical rod.

[0014] As a preferred embodiment of this utility model, a clamp is installed at the bottom of the connecting plate, a hydraulic cylinder is installed inside the clamp, and a pressure head is fixedly connected to the output end of the hydraulic cylinder.

[0015] As a preferred embodiment of this utility model, two clamps are provided, and each hydraulic cylinder is provided with a locking screw.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the push plate can be automatically pushed to the designated position by the extension rod to control the push plate, which is made of steel leaf springs after processing, without the need for manual intervention. This greatly improves the continuity and stability of the production process, reduces production interruptions caused by manual operation, and ensures the consistency of steel leaf springs in the pushing and collecting process. Since the pushing method and force are consistent, the stress state of different steel leaf springs is also more consistent, thereby improving the consistency of product quality.

[0018] 2. In this utility model, the collection box equipped with handles and wheels provides high flexibility in transporting leaf springs, enabling it to quickly reach the processing location for collection. Compared to fixed collection devices, the mobile carrier can flexibly adjust its position according to actual production needs, reducing the waste of collection time caused by unreasonable equipment layout. Traditional manual handling may require passing through multiple transfer points, while the mobile carrier can directly transport leaf springs from the processing area to the heat treatment area, greatly shortening the collection and transportation time.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0025] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0026] A preloading device for processing automotive leaf springs includes a main body 1, a pushing assembly 2 fixedly connected to the top of the main body 1, and a collecting assembly 3 provided on the side of the main body 1.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The pusher assembly 2 shown includes a support plate 201, inside which a pusher rod 202 is installed. A pusher plate 203 is fixedly connected to the output end of the pusher rod 202. The collection assembly 3 includes a collection box 301, with a handle 302 on its side and four casters 303 on its bottom. The pusher rod 202 extends the pusher plate 203, automatically pushing the processed automotive leaf springs to a designated position without manual intervention. This significantly improves the continuity and stability of the production process, reduces production interruptions caused by manual operation, and ensures the leaf springs are properly pushed and collected. Consistency is ensured because the pushing method and force are consistent, resulting in a more consistent stress state for different leaf springs, thus improving product quality consistency. The collection box 301, equipped with handles 302 and casters 303, offers high flexibility in transporting leaf springs, allowing for quick collection at the processing location. Compared to fixed collection devices, the mobile carrier can flexibly adjust its position according to actual production needs, reducing wasted collection time due to unreasonable equipment layout. Traditional manual handling may require passing through multiple transfer points, while the mobile carrier can directly transport leaf springs from the processing area to the heat treatment area, significantly shortening collection and transportation time.

[0028] In this embodiment, as Figure 1 and Figure 4As shown, the main body 1 includes a base plate 101. A support frame 103 is fixedly connected to the top of the base plate 101. A processing and placement plate 106 is fixedly connected to the top of the support frame 103. Two protective plates 107 are fixedly connected to the top of the support frame 103. Reinforcing angle aluminum 105 is fixedly connected inside the support frame 103. Four anti-slip pads 102 are fixedly connected to the bottom of the base plate 101. Two operation buttons 104 are provided on the side of the support frame 103. A vertical rod 108 is fixedly connected to the top of the base plate 101. A connecting plate 109 is fixedly connected to the top of the vertical rod 108. A bottom of the connecting plate 109 is equipped with... Clamp 110, with a hydraulic cylinder 111 installed inside. The output end of the hydraulic cylinder 111 is fixedly connected to a pressure head 112. There are two clamps 110. Each hydraulic cylinder 111 has a locking screw inside. The clamp 110 installation and fixing method can provide a reliable fixing effect, ensuring that the hydraulic cylinder 111 will not loosen or shift during the pre-compression process. The hydraulic cylinder 111 is subjected to large pressure and impact force when working. The clamp 110 can tightly fix the hydraulic cylinder 111 in the installation position, ensuring its stability during operation. The clamp 110 is usually made of high-strength material, which can withstand large tensile and compressive forces, thereby improving the structural stability of the entire pre-compression system.

[0029] The working process of this utility model is as follows: When the pre-compression device for processing automotive leaf springs designed in this scheme is in operation, the automotive leaf spring to be processed is placed on the processing placement plate 106. The hydraulic cylinder 111 is driven to lower the pressure head 112 at its bottom, thereby pre-compressing the automotive leaf spring on the processing placement plate 106. After processing, the extension rod 202 can be used to push the automotive leaf spring on the processing placement plate 106 with the push plate 203, so that the automotive leaf spring enters the collection box 301. The collected automotive leaf spring can be conveniently transported using the handle 302 and the moving wheel 303.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
