Technical Field
[0001] This utility model relates to the field of steel leaf spring processing technology, specifically a steel leaf spring cutting table. Background Technology
[0002] Automotive leaf springs, also known as leaf springs, are common elastic elements in automotive suspension systems. They are mostly used in non-independent suspension structures, especially in medium and large trucks. They are mainly made of alloy steels such as 60Si2Mn and 50CrV, and are processed through processes such as blanking, earing, quenching, and shot peening to form multiple stacked alloy springs of unequal length and curvature, which together form an elastic beam with approximately equal strength.
[0003] When cutting automotive leaf springs, manual feeding is used to position one end of the leaf spring against a positioning baffle before dimensional control and cutting. However, this process suffers from several technical defects: firstly, the leaf spring cannot be perfectly aligned with the positioning baffle; secondly, the baffle is prone to shifting during feeding, compromising its straightness. These defects lead to inaccurate leaf spring cutting dimensions. Therefore, we propose a leaf spring cutting table to address these existing technical shortcomings. Utility Model Content

A roller pressure wheel is provided at the lower end of the moving column. An elastic element is provided between the mounting frame and the moving column.
[0007] The lower end of the cutting mounting table is equipped with a hydraulic push rod, which is positioned opposite to the feeding seat. The push rod of the hydraulic push rod is equipped with a socket, which is open on the side facing the cutting hole. The bottom wall of the socket is embedded and coincides with the upper surface of the cutting mounting table. Both the upper and lower ends of the socket are equipped with electric push rods, and the push rod of the electric push rod is equipped with a pressure block, which is located inside the socket.
[0008] As a preferred technical solution of this utility model, the cutting mechanism includes a guide stand disposed on the upper end of the cutting mounting platform, a movable seat sliding outside the guide stand, the movable seat being connected to the cutting blade, and a hydraulic cylinder being disposed at the upper end of the cutting mounting platform, the push rod of the hydraulic cylinder being connected to the movable seat.
[0009] Using the above technical solution, the hydraulic cylinder on the cutting mounting platform works, pushing the moving seat to move in a directional manner outside the guide stand, and simultaneously driving the cutting blade to move down to cut the steel plate.
[0010] As a preferred embodiment of the present invention, the adjusting locking assembly includes a locking seat that slides outside the guide rod. The two front locking seats and the two rear locking seats are respectively connected to the front and rear connecting rods. A locking screw is threaded to the upper end of the locking seat, and the locking screw passes through the locking seat and contacts the guide rod.
[0011] Using the above technical solution, the locking seat moves outside the guide rod, driving the connecting rod and the vertical roller to move synchronously, thereby changing the distance between the two vertical rollers. After the adjustment is completed, the adjusted locking seat can be locked and fixed by rotating the locking screw.
[0012] As a preferred embodiment of this utility model, the connecting member includes a rotating shaft that rotates concentrically around the upper end of the vertical roller, the rotating shaft extending through to the top of the connecting rod, and the rotating shaft being locked and fixed to the connecting rod by a locking nut.
[0013] By adopting the above technical solution, the vertical roller can be easily installed and disassembled by passing the rotating shaft through the connecting rod and tightening the locking nut.
[0014] As a preferred embodiment of this utility model, the elastic element is a stainless steel spring, and when the elastic element is in a naturally contracted state, the surfaces of the roller and the feeding roller are aligned.
[0015] As a preferred embodiment of this utility model, the socket is provided with a movable rod at both the front and rear ends, and the other end of the movable rod slides within the cutting and mounting table.
[0016] Using the above technical solution, the moving rod slides within the cutting and mounting platform to provide moving support for the socket, ensuring the stability of the socket's movement.
[0017] In a preferred embodiment of this utility model, the cutting mounting table, cutting blade, feeding seat, and socket are arranged at the same center.
[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0019] This steel plate spring cutting table, based on the width of the steel plate, adjusts the locking assembly on the guide rod to move, synchronously driving the vertical rollers on the connecting rod to move, so that the distance between the front and rear vertical rollers is equal to the width of the steel plate. This facilitates the placement of the steel plate onto the feeding rollers on the cutting mounting table. Simultaneously, the vertical rollers provide lateral restraint. After restraining the steel plate, the table continues to move, passing through the pressure rollers, causing the pressure rollers to adhere to the upper surface of the steel plate. At this point, the moving column moves upward on the mounting frame, simultaneously extending the elastic element, thereby causing the pressure rollers... The steel plate is pressed onto the feeding roller. As the steel plate is pushed, it passes through the cutting mounting table and is inserted into the socket. At the same time, the electric push rod moves the pressure block to clamp the steel plate in the socket. The hydraulic push rod moves the steel plate fixed in the socket. The vertical roller, feeding roller and pressure roller limit the feeding of the steel plate, so as to achieve precise feeding of the steel plate under the limit of horizontal and vertical positioning. The cutting mechanism drives the cutting blade to move down through the cutting hole, so as to achieve precise control of the size of the steel plate for cutting. Attached Figure Description

[0030] 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.
[0031] Please see Figures 1 to 3 The steel leaf spring cutting table in this embodiment includes a cutting mounting table 1, a cutting mechanism, a feeding seat 7, and related components.
[0032] The cutting mounting table 1 serves as the basic support structure for the entire cutting table. It has a cutting hole 2, which is a rectangular hole located at the center of the cutting mounting table 1. The cutting blade 6 passes through the hole to cut the steel plate. The cutting mounting table 1 is made of high-strength alloy steel, which has sufficient rigidity and stability to withstand the huge pressure and impact generated during the cutting process, ensuring the smooth progress of the cutting process.
[0033] The cutting mounting table 1 is equipped with a cutting mechanism, which includes a guide stand 3, a movable seat 5, a cutting blade 6, and a hydraulic cylinder 4. The guide stand 3 is vertically fixed to the upper surface of the cutting mounting table 1, and has a sliding groove on its outside to guide the directional movement of the movable seat 5. The movable seat 5 is slidably connected to the outside of the guide stand 3 and fixedly connected to the cutting blade 6. The cutting blade 6 is made of high-hardness, high-wear-resistant alloy tool steel with a sharp blade, which can quickly and accurately cut steel plates. The hydraulic cylinder 4 is fixed to the upper surface of the cutting mounting table 1 by bolts, and its push rod is connected and fixed to the movable seat 5. When the hydraulic cylinder 4 works, it pushes the movable seat 5 to move directionally outside the guide stand 3, and simultaneously drives the cutting blade 6 to move down through the cutting hole 2 to cut the steel plate placed on the cutting mounting table 1.
[0034] Please see Figures 4 to 6The feeding seat 7 is fixed on the right side surface of the cutting mounting table 1. Multiple feeding rollers 8 are equidistantly rotated between the front and rear walls of its inner cavity. The feeding rollers 8 adopt a cylindrical structure with a smooth surface. They are rotatably connected to the inner wall of the feeding seat 7 through bearings and can rotate freely. The number of feeding rollers 8 is set according to the actual use, ranging from 4 to 8. The surface of the feeding rollers 8 is flush with the upper surface of the cutting mounting table 1, which facilitates the smooth movement of the steel plate from the feeding rollers 8 to the cutting mounting table 1 for cutting.
[0035] Mounting bracket 9 is fixed to the upper surface of loading seat 7. Guide rods 10 are fixed between its left and right sides and front and rear sides. The guide rods 10 are cylindrical rods, arranged in parallel, and are used to guide the movement of the adjustment and locking components.
[0036] The adjusting locking assembly includes a locking seat 11 and a locking screw 12. The locking seat 11 is slidably connected to the outside of the guide rod 10. The two front locking seats 11 and the two rear locking seats 11 are respectively connected and fixed to the front and rear connecting rods 13. The upper end of the locking seat 11 is provided with a threaded hole. The locking screw 12 is threaded into the threaded hole, passes through the locking seat 11 and contacts the guide rod 10. By rotating the locking screw 12, the friction between the locking seat 11 and the guide rod 10 can be adjusted, thereby fixing and adjusting the position of the locking seat 11 on the guide rod 10. In actual use, according to the width of the steel plate, the adjusting locking assembly moves on the guide rod 10, driving the connecting rod 13 and the vertical roller 14 to move synchronously, changing the distance between the front and rear vertical rollers 14 to be equal to the width of the steel plate, thus facilitating the placement of the steel plate on the feeding roller 8 on the cutting mounting table 1, and using the vertical roller 14 for lateral positioning.
[0037] The vertical roller 14 is mounted on the connecting rod 13 via a connector, which includes a rotating shaft 15 and a locking nut 16. The rotating shaft 15 is rotatably connected to the upper surface of the vertical roller 14 and extends through to the top of the connecting rod 13. It is locked and fixed to the connecting rod 13 by the locking nut 16, which is connected by an external thread. The vertical roller 14 is located between two adjacent feeding rollers 8. Based on the symmetrical distribution of the feeding rollers 8 in the middle, the vertical roller 14 adopts a cylindrical structure with a smooth surface and can rotate freely. During the feeding of the steel plate, it limits the side of the steel plate to ensure the straightness of the steel plate.
[0038] The movable column 17 is slidably connected to the upper end of the mounting frame 9, and a roller 19 is fitted at its lower end. The roller 19 has a cylindrical structure, a smooth surface, and can rotate freely. An elastic element 18 is fixed between the mounting frame 9 and the movable column 17. The elastic element 18 is sleeved on the outside of the movable column 17. The elastic element 18 is a stainless steel spring with good elasticity and corrosion resistance. When the elastic element 18 is in a naturally contracted state, the roller 19 is flush with the surface of the feeding roller 8. After limiting the movement of the steel plate, the steel plate continues to move, passing through the roller 19, so that the roller 19 is in contact with the upper surface of the steel plate. At this time, the movable column 17 moves upward on the mounting frame 9, and at the same time, the elastic element 18 extends, so that the roller 19 presses the steel plate onto the feeding roller 8, ensuring the stability of the steel plate during the feeding process.
[0039] Please see Figures 7 to 9 The hydraulic push rod 20 is fixed to the lower left side of the cutting mounting table 1 by bolts, and is set opposite to the feeding seat 7. A socket 21 is fixed at the push rod. The side of the socket 21 facing the cutting hole 2 is open to facilitate the insertion of the steel plate. The bottom wall of the socket 21 is embedded and coincides with the upper surface of the cutting mounting table 1 to ensure that the steel plate can be inserted into the socket 21 stably. Electric push rods 22 are fixed to the upper and lower surfaces of the socket 21 by bolts. A pressure block 23 is fixed at the push rod of the electric push rod 22. The pressure block 23 is located inside the socket 21. When the steel plate is inserted into the socket 21, the electric push rod 22 pushes the pressure block 23 to move, clamping the steel plate in the center inside the socket 21 to fix the steel plate. Then, the hydraulic push rod 20 drives the steel plate fixed in the socket 21 to move. In conjunction with the vertical roller 14, the feeding roller 8 and the roller pressure wheel 19, the steel plate is limited and fed, so that the steel plate is accurately fed under the limit of horizontal and vertical positioning.
[0040] The front and rear surfaces of the socket 21 are fixed with movable rods 24. The other end of the movable rods 24 slides in the cutting and mounting table 1. The movable rods 24 provide moving support for the socket 21, ensuring the stability of the socket 21 under the push of the hydraulic push rod 20, thereby improving the accuracy of steel plate feeding.
[0041] This steel leaf spring cutting table is equipped with a complete control system, including a hydraulic control system and an electric control system. The hydraulic control system controls the operation of the hydraulic cylinder 4 and the hydraulic push rod 20. By adjusting the pressure and flow of the hydraulic system, it achieves precise control over the cutting speed of the cutting blade 6 and the moving speed of the socket 21. The electric control system controls the operation of the electric push rod 22. By setting the extension and retraction stroke of the electric push rod 22, it achieves precise control over the moving distance of the pressure block 23, thereby ensuring that the steel plate is centered and clamped in the socket 21. The control system uses a PLC (Programmable Logic Controller) for programming control, which has the advantages of simple operation, high control accuracy, and good stability. The operator can input relevant parameters through the control panel, such as cutting size and feeding speed. The control system automatically adjusts the working status of each component according to the input parameters to achieve automated and precise cutting of the steel leaf spring.
[0042] Usage steps,
[0043] Adjust the position of the adjusting locking assembly on the guide rod 10 according to the width of the steel plate, so that the distance between the front and rear vertical rollers 14 is equal to the width of the steel plate.
[0044] The steel plate is placed on the feeding roller 8, so that one end of the steel plate passes through the gap between the vertical rollers 14. The steel plate is continued to move, so that the steel plate passes through the roller 19. The roller 19 presses the steel plate onto the feeding roller 8 under the action of the elastic element 18.
[0045] Continue pushing the steel plate until it is inserted into the socket 21. Control the electric push rod 22 through the control system to move the pressure block 23 and clamp the steel plate in the socket 21.
[0046] The control system controls the hydraulic push rod 20 to move the steel plate fixed inside the socket 21. At the same time, the vertical roller 14, the feeding roller 8 and the roller pressure wheel 19 limit the feeding of the steel plate, so that the steel plate is accurately fed under the limit of horizontal and vertical positioning.
[0047] Once the steel plate is fed to the set position, the hydraulic cylinder 4 is controlled by the control system to move the moving seat 5 outside the guide stand 3, thereby driving the cutting blade 6 to move down through the cutting hole 2 to cut the steel plate.
[0048] After cutting is completed, control the hydraulic cylinder 4 and hydraulic push rod 20 to reset, take out the cut steel plate, and repeat the above steps to cut the next steel plate.
[0049] Principles and beneficial effects
[0050] This leaf spring cutting table achieves precise cutting of leaf springs through a reasonable structural design and a sophisticated control system. During feeding, the vertical roller 14 provides lateral restraint to the steel plate, ensuring its straightness. The feeding roller 8 and the pressure roller 19 work together to keep the steel plate stable during feeding, preventing it from jumping or shifting. The socket 21 and the pressure block 23 fix the steel plate, ensuring its stability during cutting. The control system precisely controls the working state of each component, enabling precise feeding of the steel plate under horizontal and straight restraint. Then, the cutting mechanism drives the cutting blade 6 to move down through the cutting hole 2, precisely cutting the steel plate to the required dimensions. This invention solves the problem of inaccurate steel plate cutting dimensions in the prior art, improves the processing quality and production efficiency of leaf springs, and has advantages such as reasonable structure, simple operation, high control precision, and good stability. It can meet the high precision requirements of automotive suspension systems for leaf springs.
[0051] In summary, this leaf spring cutting table has significant technical advantages and broad application prospects in the field of leaf spring processing.
[0052] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
