Description

TECHNICAL FIELD

[0001] The application relates to the technical field of steel plate spring production and processing, and particularly discloses a shearing device for steel plate spring production. BACKGROUND

[0002] The steel plate spring is the most widely used elastic element in an automobile suspension, and is an approximately equal-strength elastic beam composed of a plurality of alloy spring plates of equal width but different lengths (the thicknesses can be equal or different). When the impact force of the road is transmitted to the wheel, the steel plate is deformed to play a role of buffering and vibration reduction, and when arranged in the longitudinal direction, the steel plate also plays a role of guiding force transmission.

[0003] In the production and processing of the steel plate spring, the blanking and shearing of the raw material is an inevitable production step, and the main role is to shear the raw material into a shape suitable for the length or width of the steel plate spring. In order to improve the production effect of the shearing process, a plurality of cutting blades are usually used to simultaneously shear the raw material, and the principle is that the plurality of cutting blades are installed on the cutting roller and synchronously rotate under the driving of the motor to simultaneously cut the raw material conveyed on the conveyor.

[0004] Although the cutting mode has high processing speed and shearing efficiency, in the cutting process, some cutting blades are inevitably worn and passivated, and when the cutting blades are replaced, the cutting blades on the cutting roller need to be integrally disassembled and replaced, which is not only complicated but also causes waste of part of the processing equipment and increases the production cost of the steel plate spring. Therefore, the shearing device for steel plate spring production is provided to solve the above problems. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to solve the problem that the cutting blades need to be integrally disassembled and replaced in the traditional steel plate spring production process, which is complicated and increases the production cost of the steel plate spring.

[0006] In order to achieve the above purpose, the basic scheme of the present application provides a shearing device for steel plate spring production, which comprises:

[0007] a rack;

[0008] a conveying assembly arranged on the rack and used for conveying raw material;

[0009] a shearing assembly arranged on the rack and used for shearing the raw material, comprising a cutting roller rotatably connected to the rack and a cutting wheel arranged at one end of the cutting roller, adjacent cutting roller end portions are detachably coaxially connected, and the shearing assembly further comprises a fixing member for fixing the adjacent cutting rollers;

[0010] A drive unit used to drive the individual cutting rollers to rotate synchronously.

[0011] Furthermore, one end of the cutting roller is provided with a mating groove, and the other end of the cutting roller is provided with a mating post that is adapted to the mating groove.

[0012] Furthermore, the mating groove includes a circular groove and a polygonal groove that are connected to each other, and the mating post includes a circular post and a polygonal post that are adapted to the circular groove and the polygonal groove respectively, and also includes a plurality of gaskets adapted to the circular post.

[0013] Furthermore, each of the cutting rollers is provided with a positioning ring, and the positioning ring, the washer ring, and the cutting wheel are provided with internally threaded holes that can communicate with each other. The fixing component is a fixing bolt that is adapted to the internally threaded hole.

[0014] Furthermore, the cutting wheel is provided with several connecting blocks, and the positioning ring is provided with connecting grooves that are adapted to the connecting blocks.

[0015] Furthermore, the two side walls of the washer are respectively provided with matching blocks and slots in terms of shape and position.

[0016] Furthermore, the shapes of the connecting block, connecting groove, locking block, and locking groove are mutually compatible.

[0017] Furthermore, it also includes a pressure roller mounted on the frame to press the raw material.

[0018] Furthermore, it also includes a cleaning roller mounted on the frame to remove impurities from the surface of the raw material.

[0019] The principle and effect of this solution are as follows:

[0020] Compared with existing technologies, this invention uses multiple cutting rollers and cutting wheels that work together to make each cutting wheel independent. When a cutting blade becomes worn or dull, only that blade needs to be disassembled, eliminating the need for complete disassembly and replacement. This effectively avoids the cumbersome process and increased production costs associated with traditional leaf spring production, where the cutting blades need to be completely disassembled and replaced. Furthermore, this invention uses a circular column and a washer ring to adjust the spacing between adjacent cutting blades, thus adapting to the shearing needs of leaf springs of different widths. The interplay of connecting blocks, connecting grooves, locking blocks, and locking grooves effectively prevents loosening between the fixing bolts and the internal threaded holes.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] The reference numerals in the accompanying drawings include: frame 1, conveying roller 2, motor 3, impurity removal roller 4, pressing roller 5, shearing assembly 6, shearing roller 7, mating groove 8, circular column 9, polygonal column 10, cutting wheel 11, internal threaded hole 12, connecting block 13, positioning ring 14, and washer ring 15.

[0026] A shearing device for producing leaf springs, implementing, for example Figure 1 As shown: It includes a frame 1, a conveying assembly mounted on the frame 1 for conveying raw materials, a shearing assembly 6 mounted on the frame 1 for shearing raw materials, a pressing roller 5 mounted on the frame 1 for pressing raw materials, a cleaning roller 4 mounted on the frame 1 for removing impurities from the surface of raw materials, and a driving component for driving the conveying assembly, the shearing assembly 6, the pressing roller 5 and the cleaning roller 4.

[0027] The driving component is a motor 3 mounted on the frame 1. The conveying assembly consists of several conveying rollers 2 mounted on the frame 1 and rotating synchronously. Adjacent conveying rollers 2 are connected by chain drive. One of the conveying rollers 2 is connected to the output shaft of the motor 3 via belt drive. There are two pressing rollers 5 that are symmetrically rotatably connected to the frame 1. The pressing rollers 5 are driven by a gear pair. One of the pressing rollers 5 is connected to the output shaft of the motor 3 via belt drive. There are two impurity removal rollers 4 that are symmetrically rotatably connected to the frame 1. The impurity removal rollers 4 are driven by a gear pair. One of the impurity removal rollers 4 is connected to the output shaft of the motor 3 via belt drive. The surface of the impurity removal roller 4 is in contact with the surface of the raw material and rolls.

[0028] like Figure 2As shown, the shearing assembly 6 includes a cutting roller rotatably connected to the frame 1, a cutting wheel 11 located at one end of the cutting roller, and a fixing member for fixing adjacent cutting rollers. The ends of adjacent cutting rollers are detachably coaxially connected. Specifically, one end of the cutting roller is provided with a mating groove 8, and the other end of the cutting roller is provided with a mating post adapted to the mating groove 8. The mating groove 8 includes a circular groove and a polygonal groove connected to each other. The mating post includes a circular post 9 and a polygonal post 10 adapted to the circular groove and the polygonal groove, respectively. It also includes a number of washers 15 adapted to the circular post 9. By configuring different numbers of washers 15, the distance between adjacent cutting wheels 11 can be adjusted, thereby making the sheared raw material form different widths.

[0029] Each cutting roller is equipped with a positioning ring 14. The positioning ring 14, the washer ring 15, and the cutting wheel 11 are provided with internal threaded holes 12 that can communicate with each other. The fixing component is a fixing bolt that is adapted to the internal threaded hole 12. In order to prevent the fixing screw from loosening during high-speed rotation, several connecting blocks 13 are also provided on the cutting wheel 11. The positioning ring 14 is provided with a connecting groove that is adapted to the connecting block 13. The two side walls of the washer ring 15 are respectively provided with a matching block and a slot, and the shapes of the connecting block 13, the connecting groove, the block and the slot are adapted to each other.

[0030] Compared with the prior art, this embodiment sets up multiple cutting rollers and cutting wheels 11 to cooperate with each other, so that each cutting wheel 11 is independent. When a certain cutting blade is worn or dulled, the corresponding cutting blade can be disassembled, without the need for overall disassembly and replacement. This effectively avoids the problem of the traditional steel leaf spring production process, where the cutting blades need to be disassembled and replaced as a whole, which is cumbersome and increases the production cost of steel leaf springs. In addition, this utility model uses the cooperation between the circular column 9 and the washer ring 15 to adjust the spacing between adjacent cutting blades, thereby adapting to the shearing needs of steel leaf springs of different widths. Furthermore, the cooperation between the connecting block 13, the connecting groove, the locking block and the locking groove effectively avoids the problem of loosening between the fixing bolt and the internal threaded hole 12.
