Description

Technical Field

[0001] This utility model relates to the field of spring production technology, and in particular to a multi-station collaborative continuous spring production device. Background Technology

[0002] With the automation upgrade of the manufacturing industry, the demand for springs, as a key basic component, has surged in the automotive, electronics and other fields. Traditional spring production relies on single-machine operation, which suffers from low efficiency, poor consistency and high dependence on manual labor, making it difficult to meet the requirements of modern industry for high precision and large-volume delivery. Therefore, there is an urgent need to develop multi-station collaborative continuous production equipment to realize automated and integrated processing of springs, thereby improving product quality, production efficiency and flexible manufacturing capabilities, and aligning with the development trend of intelligent manufacturing.

[0003] To address this, patent CN215032842U discloses a continuous production device for automotive spring sheets, including a conveying device and a forming device. The conveying device mainly includes a conveyor frame, a drive roller, a driven roller, a conveyor belt, and a motor. The drive roller and the driven roller are rotatably connected to both ends of the conveyor frame via drive shafts and driven shafts, respectively. The conveyor belt drives between the drive roller and the driven roller. One end of the drive shaft is equipped with a gear, and a drive shaft is rotatably connected to the conveyor frame below the drive shaft. A turntable is located at the end of the drive shaft below the gear. The edge of the turntable has a section of arc-shaped meshing columns, and the gear meshes with the meshing columns. The motor is located at the end of the drive shaft away from the turntable. This invention, through the cooperation of the turntable and the gear, can intermittently drive the material belt forward by a fixed displacement, allowing the material belt to enter the next processing step precisely, achieving continuous processing and forming without manual positioning, resulting in high-precision products.

[0004] Although the aforementioned continuous production device for automotive spring sheets can achieve continuous processing and forming, friction can easily occur if the material belt comes into contact with the equipment during the conveying process, affecting the quality of the product. Therefore, it is necessary to design a multi-station collaborative continuous production device for springs. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station collaborative spring continuous production device to solve the defect in existing multi-station collaborative spring continuous production devices where friction easily occurs when the material belt comes into contact with the equipment during the conveying process, affecting the quality of the product during processing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-station collaborative spring continuous production device, including a base;

[0007] A support plate is fixed to one side of the top of the base, a rotating structure is fixed to the outer wall of one side of the support plate, a limit seat is fixed to one side of the rotating structure, and a material belt passes through the inside of the limit seat;

[0008] A lubrication structure is fixed on the outer wall of the support plate on the side away from the rotating structure. The lubrication structure includes a protective sleeve fixed on the outer wall of the support plate on the side away from the rotating structure. A protective side plate is fixed on the inner wall of the protective sleeve on the side away from the support plate. An oil inlet pipe is fixed on the top of the protective sleeve. A piston is interference-fitted to the bottom of the protective sleeve.

[0009] A pressing structure is fixed on the outer wall of the top side of the base.

[0010] Furthermore, a cutting structure is fixed on one side of the outer wall of the support plate, and a forming structure is fixed on the other side of the outer wall of the support plate.

[0011] Furthermore, the rotating structure includes a disc, a servo motor, a connecting shaft, a drive gear disc, and a driven gear disc. The disc is rotatably connected to the outer wall of the top side of the support plate. The driven gear disc is fixed on the outer wall of the disc. The servo motor is fixed on the outer wall of the top of the support plate away from the disc. The output end of the servo motor is fixed to the connecting shaft. One end of the connecting shaft passes through the support plate and is fixedly connected to the drive gear disc.

[0012] Furthermore, the drive gear disk and the driven gear disk are meshed together.

[0013] Furthermore, the top of the oil inlet pipe is connected to a lubricating oil tank, and a valve is installed inside the oil inlet pipe. The central axis of the protective sleeve and the protective side plate is collinear with the central axis of the material belt.

[0014] Furthermore, the pressing structure includes a top plate, a first hydraulic rod, and a pressure block. The top plate is fixed to the outer wall of the support plate near the side of the disc. The bottom end of the top plate is fixed with the first hydraulic rod, and the bottom end of the first hydraulic rod is fixed with the pressure block.

[0015] Furthermore, the cutting structure includes a side support plate, a second hydraulic rod, and a cutter. The side support plate is fixed to the outer wall of one side of the bottom of the support plate. The second hydraulic rod is fixed to the side of the side support plate near the material belt, and a cutter is fixed to one end of the second hydraulic rod.

[0016] Furthermore, one end of the material strip extends to the outside of the limiting seat, and the other end of the material strip passes through the disc and the support plate and is fixedly connected to the output end of the feeder.

[0017] Furthermore, the forming structure includes a mounting plate, a third hydraulic rod, and a forming shaft. The mounting plate is fixed to the outer wall of one side of the bottom of the support plate. The third hydraulic rod is fixed to the side of the mounting plate near the material strip, and a forming shaft is fixed to one end of the third hydraulic rod.

[0018] The advantages of the multi-station collaborative continuous spring production device provided by this utility model are as follows:

[0019] By incorporating a lubrication structure, lubricating oil can be dripped onto the surface of the conveyor belt at regular intervals and in measured quantities through the oil inlet pipe during continuous feeding. The lubricating oil drips onto the surface of the conveyor belt, effectively reducing the friction between the conveyor belt and each station, thus reducing conveyor belt wear. When the conveyor belt enters the support plate and disc, excess lubricating oil is blocked by the support plate inside the protective sleeve. It can be periodically discharged outwards by the piston, reducing waste. This structure reduces the operating resistance of the equipment, improves the operational stability and service life of the entire device, and enables the device to facilitate conveyor belt lubrication, thereby enhancing the convenience of using this multi-station collaborative spring continuous production device.

[0020] By incorporating a rotating structure, a servo motor can drive a disc to rotate. When the disc rotates, it drives a limit seat to rotate, which in turn drives a material strip to rotate. This facilitates bending and processing of the material strip at other workstations, making it easier to form springs. This device achieves the function of easily driving the limit seat to rotate, improving the convenience and efficiency of the multi-station collaborative spring continuous production device during use.

[0021] By incorporating a pressing structure, a cutting structure, and a forming structure, the first hydraulic rod drives the pressure block to press down, bending and deforming the material strip. The third hydraulic rod drives the forming shaft to the bottom of the material strip, providing a central axis for spring forming, allowing the spring to rotate around the forming shaft during forming. The second hydraulic rod drives the cutter to move quickly, facilitating the cutting of the formed spring and enabling subsequent continuous processing. This device achieves multi-station collaborative spring production, improving the working efficiency of this multi-station collaborative continuous spring production device.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 The present invention provides a multi-station collaborative spring continuous production device, including a base 1.

[0030] Reference Figures 1-5 A support plate 2 is fixed to one side of the top of the base 1. A rotating structure 3 is fixed to the outer wall of one side of the support plate 2. The rotating structure 3 includes a disc 31, a servo motor 32, a connecting shaft 33, a drive gear 34, and a driven gear 35. The disc 31 is rotatably connected to the outer wall of the top side of the support plate 2. The driven gear 35 is fixed to the outer wall of the disc 31. The servo motor 32 is fixed to the outer wall of the top of the support plate 2 away from the disc 31. The output end of the servo motor 32 is fixed to the connecting shaft 33. One end of the connecting shaft 33 passes through the support plate 2 and is fixedly connected to the drive gear 34. The drive gear 34 and the driven gear 35 are meshed. A limit seat 8 is fixed to one side of the rotating structure 3. A material belt 7 passes through the inside of the limit seat 8. One end of the material belt 7 extends to the outside of the limit seat 8. The other end of the material belt 7 passes through the disc 31 and the support plate 2 and is fixedly connected to the output end of the feeder.

[0031] When an external power source is connected and the servo motor 32 is started, the servo motor 32 will drive the connecting shaft 33 to rotate, which in turn drives the drive gear 34 fixed at the end of the connecting shaft 33 to rotate. The drive gear 34 meshes with the driven gear 35 fixed on the outer wall of the disc 31. Therefore, the continuous rotational motion of the drive gear 34 is converted into the rotational motion of the driven gear 35 and the disc 31. The material strip 7 passes through the disc 31 and the limiting seat 8 and is limited by the limiting seat 8 through the circular groove inside the limiting seat 8. When the disc 31 rotates, the disc 31 will drive the material strip 7 to rotate through the limiting seat 8. This makes it easy to change the bending angle and forming angle of the material strip 7 during the spring forming process. The servo motor 32 is programmed and controlled by the control system. Its rotation angle and pause time are strictly synchronized with the action rhythm of each subsequent station to ensure that the material strip 7 can accurately stop at the predetermined position after each movement.

[0032] Reference Figure 2 , Figure 3 and Figure 5 A lubrication structure 4 is fixed on the outer wall of the support plate 2 away from the rotating structure 3. The lubrication structure 4 includes a protective sleeve 41 fixed on the outer wall of the support plate 2 away from the rotating structure 3. A protective side plate 42 is fixed on the inner wall of the protective sleeve 41 away from the support plate 2. An oil inlet pipe 43 is fixed on the top of the protective sleeve 41. A piston 44 is interference-fitted to the bottom of the protective sleeve 41. A lubricating oil tank is connected to the top of the oil inlet pipe 43. A valve is installed inside the oil inlet pipe 43. The central axis of the protective sleeve 41 and the protective side plate 42 is collinear with the central axis of the material belt 7.

[0033] The top of the oil inlet pipe 43 is connected to a lubricating oil tank. The lubricating oil flows into the pipe by gravity. The valve installed inside the oil inlet pipe 43 can control the opening and closing of the oil circuit. The protective sleeve 41 and the protective side plate 42 together form a cavity surrounding the material belt 7. When the valve is opened, the lubricating oil drips from the oil inlet pipe 43 onto the top surface of the material belt 7. Then, the excess lubricating oil will flow into this cavity. The lubricating oil soaks into the cavity and adheres to the surface of the continuously passing material belt 7, achieving uniform lubrication. The piston 44 is connected to the bottom of the protective sleeve 41 by interference fit. When there is a lot of oil in the cavity, the piston 44 can be opened to discharge the excess lubricating oil and put it back into the lubricating oil tank for easy reuse.

[0034] Reference Figures 1-5A pressing structure 5 is fixed to the outer wall of one side of the top of the base 1. The pressing structure 5 includes a top plate 51, a first hydraulic rod 52, and a pressure block 53. The top plate 51 is fixed to the outer wall of the top of the support plate 2 near the disc 31. The bottom end of the top plate 51 is fixed to the first hydraulic rod 52, and the bottom end of the first hydraulic rod 52 is fixed to the pressure block 53. A cutting structure 6 is fixed to the outer wall of one side of the support plate 2. The cutting structure 6 includes a side support plate 61, a second hydraulic rod 62, and a cutter 63. The side support plate 61 is fixed to the support plate 2. On the outer wall of the bottom side of the support plate 2, a second hydraulic rod 62 is fixed to the side support plate 61 near the material belt 7. A cutter 63 is fixed to one end of the second hydraulic rod 62. A forming structure 9 is fixed to the outer wall of the other side of the support plate 2. The forming structure 9 includes a mounting plate 91, a third hydraulic rod 92 and a forming shaft 93. The mounting plate 91 is fixed to the outer wall of the bottom side of the support plate 2. The third hydraulic rod 92 is fixed to the side of the mounting plate 91 near the material belt 7. A forming shaft 93 is fixed to one end of the third hydraulic rod 92.

[0035] With an external power supply, the first hydraulic rod 52 is activated, which drives the pressure block 53 to press down. When the pressure block 53 presses down, it can bend the material strip 7 downwards. By rotating the material strip 7 through the rotating structure 3, the direction of the material strip 7 is changed, and the material strip 7 can be bent again to facilitate the manufacturing of the connection between the two ends of the spring. The third hydraulic rod 92 is activated, which drives the shaping shaft 93 to approach the material strip 7. The shaping shaft 93 is located below the material strip 7. At this time, the pressure block 53 is lowered to above the material strip 7 and the material strip 7 is continuously conveyed. Under the constraint of the pressure block 53 and the shaping shaft 93, the material strip 7 will continuously rotate around the shaping shaft 93 to form a spring segment. Then, the tail end of the spring is bent again by the pressure block 53 to complete the spring manufacturing. After the spring is manufactured, the second hydraulic rod 62 is activated, which drives the cutter 63 to quickly impact the material strip 7 and cut it.

[0036] 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.
