Description

Technical Field

[0001] This utility model relates to the field of leaf spring technology, specifically to a leaf spring cutting and severing device. Background Technology

[0002] Leaf springs are made of multiple steel plates of unequal length and curvature stacked together. After installation, the two ends naturally bend upward. When the impact force of the road surface on the wheel is transmitted, the steel plate deforms, which plays a role in buffering and damping. When arranged longitudinally, it also plays a role in guiding and transmitting force. Most non-independent suspensions use leaf springs as elastic elements, which can eliminate the need for guiding devices and shock absorbers, and the structure is simple.

[0003] When cutting leaf springs, the long strip of sheet material is manually pushed to contact the adjustable end limit plate before the equipment is started to cut the sheet material. However, the pushed steel plate does not have a four-sided limiting structure, which causes the steel plate to bend and deviate during feeding and being cut. It cannot be guaranteed that the steel is cut in a straight state, which affects the accuracy of the steel cutting dimensions and leads to waste of material in subsequent processing. Therefore, we propose a leaf spring cutting and cutting device to solve this technical defect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel leaf spring cutting and severing device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel leaf spring cutting and cutting device, including a machine body base, a hydraulic cylinder disposed at the upper end of the machine body base, a cutting blade disposed at the push rod of the hydraulic cylinder, electric push rods symmetrically disposed on the left and right sides of the machine body base based on the middle, and a limiting clamping plate disposed at the push rod of the electric push rod located in front of the cutting blade;

[0006] A hydraulic push rod is provided in the middle of the rear side of the machine base. A moving rod is provided at the push rod of the hydraulic push rod, which passes straight through to the other side of the machine base. A limiting base plate is provided at the upper end of the other end of the moving rod. A support frame is provided at the top of the limiting base plate. A hydraulic push rod is provided at the top of the support frame. A limiting top plate is provided at the push rod of the hydraulic push rod. A limiting top plate is provided above the limiting base plate and aligned on all four sides. Rubber rollers are rotatably mounted on the left and right side walls of the inner cavity of the limiting base plate. The opposite surfaces of the limiting base plate and the limiting top plate are open. The outside of the rubber rollers is located outside the opening.

[0007] The front side of the limiting base plate is provided with a limiting adjustment component to limit the sheared steel leaf spring.

[0008] By employing the above technical solution, the sheet material is placed between the limiting clamps on the machine base, and the limiting clamps are moved towards each other by an electric push rod, thus achieving two-sided clamping and limiting of the sheet material. After limiting, the sheet material is moved between the rubber rollers on the limiting bottom plate and the limiting top plate, with the lower surface of the sheet material contacting the lower rubber roller. Simultaneously, the hydraulic push rod on the support frame pushes the rubber roller on the limiting top plate downward to contact the upper surface of the sheet material, thereby achieving four-sided limiting of the conveyed sheet material. After limiting, the sheet material is cut to the required length by rotating the limiting adjustment component to move and limit the sheet material until it contacts the limiting adjustment component. This ensures that the sheet material is fed in while being limited on four sides, guaranteeing the straightness of the sheet material, avoiding bending and misalignment, and ensuring the accuracy of the cutting length.

[0009] As a preferred technical solution of this utility model, the left and right side walls of the inner cavity of the machine body are provided with cutting blade guide rails for the cutting blade to move linearly and vertically.

[0010] By adopting the above technical solution, the cutting blade can move linearly and be limited within the cutting blade guide rail, thus ensuring the stability of the cutting process.

[0011] As a preferred technical solution of this utility model, the upper end of the machine body base is provided with a limiting groove for the limiting clamp to slide linearly.

[0012] By adopting the above technical solution, the limiting clamp can be stably limited and moved within the limiting groove, thereby improving the stability of the limiting clamp.

[0013] As a preferred technical solution of this utility model, there is a gap between the rubber rollers, and the limiting adjustment component includes a threaded seat located in the middle of the front surface of the limiting base plate. The threaded seat is internally threaded with a threaded adjusting rod that passes through the threaded seat, and the rear end of the threaded adjusting rod is provided with a limiting head.

[0014] By adopting the above technical solution, the thread adjusting rod on the threaded seat is screwed in, which drives the limit head to move synchronously, so that the limit head limits the feeding of steel and controls the cutting length of steel.

[0015] As a preferred embodiment of this invention, when the top rubber roller contacts the bottom rubber roller, the limiting head is located within the gap between the rubber rollers.

[0016] By adopting the above technical solution, it is ensured that the limiting head will not obstruct the movement of the rubber roller.

[0017] As a preferred embodiment of this utility model, the upper surface of the bottom limiting head is flush with the upper surface of the body base.

[0018] With the above technical solution, the surface of the bottom rubber roller is flush with the upper surface of the machine body base.

[0019] As a preferred technical solution of this utility model, the lower surface of the steel can be supported in a plane by the machine body base and the surface of the bottom rubber roller.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] This steel plate spring cutting device achieves two-sided clamping and limiting of the plate by placing the plate between the limiting clamps on the machine base and pushing the limiting clamps to move towards each other via an electric push rod. After the limiting is completed, the plate is pushed to move between the rubber rollers on the limiting bottom plate and the limiting top plate, and at the same time, the lower surface of the plate contacts the rubber roller below. In conjunction with the hydraulic push rod two set on the support frame, the rubber roller on the limiting top plate is pushed down to contact the upper surface of the plate, thereby achieving four-sided limiting of the conveyed plate.

[0022] After the limiting is completed, the material is cut to the required length. The limiting bottom plate and limiting top plate on the moving rod are moved together by the hydraulic push rod, and the material is moved and limited by rotating the limiting adjustment component. The material is moved until it contacts the limiting adjustment component, which ensures that the material is fed in while the material is limited on four sides. Compared with the existing technology, this ensures the straightness of the feeding material, avoids bending and positioning, and ensures the accuracy of the cutting length.

The base 1 is the basic component of the entire device and is made of high-strength cast iron. The upper surface of the base 1 is fixed with a hydraulic cylinder 2 by bolts. The hydraulic cylinder 2 uses high-performance hydraulic components, which can provide strong thrust to ensure that the cutting blade 3 accurately cuts the leaf spring. The cutting blade 3 is connected and fixed at the push rod of the hydraulic cylinder 2. The cutting blade 3 is made of high-hardness alloy steel, which has a sharp blade and good wear resistance, and can efficiently complete the cutting work.

[0030] Electric push rods 4 and limiting clamps 5 are symmetrically fixed on the left and right sides of the machine body 1 based on the middle. The electric push rods 4 are made of high-precision electric components, which can accurately control the movement position of the limiting clamps 5. The limiting clamps 5 are connected and fixed at the push rod of the electric push rods 4. The limiting clamps 5 are made of high-strength aluminum alloy material, which has good strength and toughness and can limit the left and right sides of the plate to prevent displacement. The upper end of the machine body 1 is provided with a limiting groove 6 for the linear sliding of the limiting clamps 5. The setting of the limiting groove 6 ensures the stability and linearity of the limiting clamps 5 during the movement process.

[0031] Hydraulic push rod 7 and moving rod 8 are bolted to the middle of the rear surface of the machine body base 1. Hydraulic push rod 7 is selected from hydraulic components that match hydraulic cylinder 2 and can provide stable thrust. The push rod of hydraulic push rod 7 is connected and fixed to a moving rod 8 that runs straight through to the front surface of the machine body base 1. The moving rod 8 is made of high-strength alloy steel and has high strength and rigidity to ensure stability when pushing the limit base plate 9 to move.

[0032] The limiting base plate 9 and the support frame 10 are fixed on the upper front surface of the moving rod 8. The limiting base plate 9 is made of thick steel plate, which has a large load-bearing capacity and good stability. The top of the limiting base plate 9 is fixed with the support frame 10. The support frame 10 is made of steel structure, which has high strength and stability and can provide reliable support for the hydraulic push rod 11.

[0033] The hydraulic push rod 11 and the limiting top plate 12 are bolted to the top of the support frame 10. The hydraulic push rod 11 also uses high-performance hydraulic components, which can accurately control the up and down movement of the limiting top plate 12. The limiting top plate 12 is connected and fixed at the push rod of the hydraulic push rod 11. The limiting top plate 12 is made of high-strength steel plate and its shape matches the limiting bottom plate 9. It can work together with the limiting bottom plate 9 to limit the steel leaf spring on four sides, ensuring the stability and accuracy of the steel leaf spring during the cutting process.

[0034] Rubber rollers 13 and limit adjustment components are rotatably mounted on the left and right side walls of the inner cavity of the limit base plate 9. The rubber rollers 13 are made of wear-resistant rubber material, which has good elasticity and friction, and can provide stable support and transmission for the leaf spring. The opposing surfaces of the limit base plate 9 and the limit top plate 12 are open, and the outside of the rubber rollers 13 is located outside the opening, ensuring that the leaf spring can be smoothly entered and clamped between the rubber rollers 13. There is a gap between the rubber rollers 13. The front side of the limit base plate 9 is provided with a limit adjustment component to limit the sheared leaf spring. The limit adjustment component includes a threaded seat 14 fixed to the middle of the front surface of the limit base plate 9. The threaded seat 14 is internally threaded with a threaded adjustment rod 15 that passes through the threaded seat 14. The rear end of the threaded adjustment rod 15 is fixed with a limit head 16. By rotating the threaded adjustment rod 15, the limit head 16 can be moved back and forth to achieve precise adjustment of the cutting length of the leaf spring.

[0035] It should be added that when the top rubber roller 13 contacts the bottom rubber roller 13, the limiting head 16 is located in the gap between the rubber rollers 13, and the surface of the bottom rubber roller 13 is flush with the upper surface of the machine body base 1.

[0036] The cutting blade guide rail 17 is fixed on both the left and right side walls of the inner cavity of the machine body 1, allowing the cutting blade 3 to move linearly and vertically. The cutting blade guide rail 17 adopts a high-precision guide rail manufacturing process to ensure the straightness and stability of the cutting blade 3 during the up and down movement, thereby improving the cutting accuracy and quality.

[0043] Push the leaf spring material to move it onto the rubber roller 13 between the bottom limiting plate 9 and the top limiting plate 12. At this time, the lower surface of the leaf spring material contacts the bottom rubber roller 13.

[0044] Start the hydraulic push rod 11 to push the limiting top plate 12 downward, so that the top rubber roller 13 contacts the upper surface of the steel leaf spring material, thereby limiting the steel leaf spring material on all four sides and ensuring that it will not bend or shift during the cutting process.

[0045] According to the required cutting length, the limiting bottom plate 9 and the limiting top plate 12 on the moving rod 8 are moved as a whole by the hydraulic push rod 7, and the position of the limiting head 16 is adjusted by rotating the threaded adjusting rod 15, so that the steel leaf spring material moves to the position of contacting the limiting head 16, thus completing the precise adjustment of the length.

[0046] Start hydraulic cylinder 2 to push cutting blade 3 downward along cutting blade guide rail 17 to cut the steel leaf spring material. After cutting is completed, hydraulic cylinder 2 returns and cutting blade 3 resets.

[0047] Release the electric push rod 4 and the hydraulic push rod 11, remove the cut leaf spring, and proceed to the next step of processing or treatment.

[0048] Equipment maintenance and upkeep include regular checks of the operating status of hydraulic cylinder 2, electric push rod 4, hydraulic push rod 1 7, and hydraulic push rod 2 11 to ensure normal operation. If any abnormalities are found, repair or replace them promptly.

[0049] Regularly clean debris and dust from components such as the machine base 1, limit clamp 5, limit bottom plate 9, and limit top plate 12 to keep the equipment clean.

[0050] Regularly clean and lubricate the cutting blade guide rail 17 and the limiting slide 6 to ensure smooth movement of the cutting blade 3 and the limiting clamp 5.
