Description

Technical Field

[0001] This utility model relates to the field of spring tooling technology, and in particular to a tooling for processing helical springs. Background Technology

[0002] Coil springs are widely used chassis components in automobiles, primarily for damping impacts or vibrations. Compared to traditional metal coil springs, composite material coil springs can be designed to be stronger, have better corrosion resistance, longer fatigue life, and can reduce weight by approximately 50%.

[0003] Chinese Patent CN221913234U discloses a shock absorber helical spring forming fixture, including a first base, a first motor mounted on the upper outer surface of the first base, a turntable mounted on the side of the first base, a cylinder housed inside the turntable, a pressure rod mounted at one end of the cylinder, a recovery box positioned between the second base and the first base, a hydraulic rod mounted inside the upper part of the second base, a connecting rod mounted on the side of the second base, and a fixing rod mounted on the side of the connecting rod. This shock absorber helical spring forming fixture utilizes a third motor to drive rollers to transport heated raw materials, a cylinder to control the pressure rod to fix one end of the raw material, forming pulleys to fix the raw material to the outside of the hydraulic rod, and a first motor to drive the turntable to rotate, thereby forming the spring.

[0004] When producing helical springs of different specifications, existing tooling requires the replacement of core components such as hydraulic rods and forming pulleys. The replacement requires the complete disassembly of the components, which increases production preparation time and cost, reduces the versatility of the structure, and the recycling bin can only collect solid waste generated during the spring forming process. The handling of metal shavings and dust that may be generated during the production process is also problematic, as the dust will spread and pollute the working environment, affecting the health of the workers.

[0032] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0033] Example 1

[0034] like Figure 1 - Figure 5 As shown, the present invention proposes a helical spring processing fixture, comprising: a base a1, a base b2, a forming component, and a recycling component; the base b2 is connected to one side of the base a1; the base b2 is connected to a hydraulic rod 201, one end of the hydraulic rod 201 is connected to a connecting piece, and the connecting piece is connected to a sleeve rod 204; the forming component is connected to one side of the base a1 and the base b2; the forming component includes a column 3, a support plate 301, an electric telescopic rod a302, an adjusting rod 303, a mounting rod 304, and a forming pulley 305; the support plate 301 is connected to both sides of one end of the column 3, and the support plate 301 is connected to the electric telescopic rod a302 respectively. The drive end of the telescopic rod a302 is connected to the adjusting rod 303, and the adjusting rod 303 is connected to the mounting rod 304. The two mounting rods 304 are connected to the forming pulley 305. The recycling assembly is connected between the base a1 and the base b2. The recycling assembly includes a recycling box 4, an air duct 401, an exhaust fan 402, and a filter bag 403. The recycling box 4 is connected between the base a1 and the base b2. The recycling box 4 is connected to the exhaust fan 402 through the air duct 401. The exhaust fan 402 is connected to the filter bag 403. The inner wall of the recycling box 4 is connected to a baffle 404. Support rods 405 are connected to both sides of the inner wall of the recycling box 4 to support the baffle 404. The connection between the forming pulley 305 and the mounting rod 304 can adopt a keyway combination structure. A rectangular keyway is machined on the outer wall of the mounting rod 304, and a corresponding key block is set on the inner wall of the forming pulley 305. These are then locked in place with bolts. Simultaneously, a displacement sensor can be added to the electric telescopic rod a302 to provide real-time feedback on the movement distance of the adjustment rod 303. Combined with a tooling control system, digital adjustment is achieved, eliminating the need for repeated manual measurements of the mounting rod 304 spacing and improving the switching efficiency of springs of different specifications. The filter bag 403 can be connected to the exhaust port of the exhaust fan 402 using a quick-release buckle for replacement. There is no need to disassemble the air duct 401, and an anti-static coating can be added to the outer layer of the filter bag to prevent metal dust from agglomerating due to electrostatic adsorption, ensuring the air permeability of the filter bag and extending the continuous working time of the exhaust fan 402. The baffle 404 is provided with filter holes. When solid waste is recycled, solid waste larger than the diameter of the filter holes is blocked on the baffle 404, preventing solid waste from affecting the exhaust fan 402 and the filter bag 403. Large solid waste particles blocked on the baffle 404 are cleaned by the staff according to the amount of solid waste recycled, preventing solid liquid from leaking from the inside of the recycling box 4.

[0035] To further explain, the connector includes a mounting block 202, a connecting block 203, a locking block 205, a locking groove 206, and a rubber pad 207. The mounting block 202 and the connecting block 203 are provided with through holes at their four corners. The mounting block 202 is connected to the locking block 205, and the connecting block 203 is provided with a locking groove 206. The inner side wall of the locking groove 206 is connected to the rubber pad 207. The locking block 205 is connected in the locking groove 206. The mounting block 202 and the connecting block 203 can be fixedly and detachably connected. During the installation of mounting block 202 and connecting block 203, firstly, the locking block 205 is connected to the locking slot 206 to align the structural through holes. Then, high-strength bolts and nuts are used, with the bolts passing through the through holes and the nuts threaded together to secure them, thus installing mounting block 202 and connecting block 203. Connecting block 203 and sleeve rod 204 are set one-to-one. When it is necessary to replace sleeve rod 204, the original connecting block 203 is disassembled. The original connecting block 203 causes the sleeve rod 204 and tooling equipment to be disassembled, and then the adapted sleeve rod 204 is connected via the connecting block 204. The connecting block 203 is installed and used. A wear-resistant copper sleeve is added to the inner wall of the through hole. The copper sleeve can not only reduce the direct friction wear between the bolt and the through hole and extend the service life of the component, but also compensate for assembly errors through slight deformation, ensuring the fit between the mounting block and the connecting block after the bolt is tightened, and preventing the sleeve rod 204 from radially shifting during processing. At the same time, the rubber pad 207 can be made of oil-resistant nitrile rubber, which can not only enhance the snap-fit ​​sealing and prevent metal chips from entering the slot and affecting disassembly, but also adapt to the possible corrosion of cutting fluid in the processing environment, improving the environmental adaptability of the connector.

[0036] Further explanation: A fixed base 5 is connected to one side of the base b2. A movable block 501 is slidably connected inside the fixed base 5. The movable block 501 has a threaded hole, through which a threaded rod is threadedly connected. One end of the threaded rod is connected to a fixed rod 502. One side of the movable block 501 is connected to the drive end of an electric telescopic rod b504, which is connected to the base b2. Slider blocks are connected to both sides of the movable block 501, sliding within grooves located on the upper and lower sides of the inner wall of the fixed base 5. The fixed rod 502 is connected to one side of the movable block 501 via a threaded rod and threaded hole, forming a helical spring. The telescopic end of the electric telescopic rod b504 passes through the base b2 and connects to the movable block 501. During the movement of the movable block 501 via the electric telescopic rod b504, the sliders on both sides move along the grooves, facilitating smoother movement of the movable block 501 and improving the usability of the fixed rod 502.

[0037] Example 2

[0038] like Figure 1 and Figure 5 As shown, the present invention proposes a helical spring processing fixture. Based on the above embodiments, this embodiment also details the specific components of the base a1 and the forming assembly, as well as their mating methods.

[0039] To further explain, base a1 is connected to servo motor a101, and a turntable is connected to the side of base a1. A connecting flange is provided between the turntable and base a1. A limit post 102 is provided on the side of the turntable, and a cylinder is installed inside the turntable, with a pressure rod at one end of the cylinder. The structure of base a1 and limit post 102 here is built based on existing mature technology, and its specific composition and working principle have formed a standardized understanding in the industry, so there is no need to elaborate on the details here.

[0040] To further explain, the molding assembly also includes an electric telescopic column 306, a movable support 307, a movable component 308, and a base c309; the electric telescopic column 306 is connected to the movable support 307, and the movable support 307 is connected to the base c309 through the movable component 308; the telescopic end of the electric telescopic column 306 is connected to the column 3, and the base c309 is connected to one side of the recycling bin 4. The movable component 308 includes a threaded rod, two guide rods, and a servo motor b. One end of the threaded rod passes through the base c309 and is connected to the servo motor b, which is located on the outer wall of the base c309. The other end of the threaded rod rotates and connects to the base c309. The threaded rod is also connected to the movable bracket 307. The two guide rods are connected inside the base c309 and are located on both sides of the threaded rod. The two guide rods are connected through the two sides of the movable bracket 307. The movable component 308 enables the movable bracket 307 to move linearly, thereby driving the electric telescopic column 306. The electric telescopic column 306 drives the column 3 to move and moves the connecting parts of the column 3. The electric telescopic column 306 facilitates height adjustment of the column 3 and allows for convenient addition of molding components.

[0041] The working principle of this utility model is as follows: During use, the raw material is conveyed through a feeding frame. The feeding machine's structure is built based on existing mature technology, and its specific composition and working principle have been standardized in the industry, therefore no further details are needed. A cylinder controls a pressure rod to limit and fix one end of the spring. Hydraulic rod 201 connects one end of the sleeve rod 204 to the turntable. A limiting post 102 limits its movement. Moving component 308 drives moving bracket 307, which in turn drives column 3 via electric telescopic column 306. Column 3 drives the connected forming pulley 305 to compress the spring. After the spring is formed, hydraulic rod 201 is controlled to reset sleeve rod 204 in the opposite direction. The formed spring can then be removed from sleeve rod 204 via fixing rod 502. When processing helical springs of different specifications, the flange structure connecting connecting block 203 and mounting block 202 is disassembled. Connecting block 203 causes sleeve rod 204 to disassemble, and then a sleeve rod 204 of the appropriate size is replaced for use. The forming pulley 305 is then disassembled on both sides and the mounting rod 304. The electric telescopic rod a302 is operated to activate it. The electric telescopic rod a302 moves the adjusting rod 303, which in turn moves the mounting rod 304, thus adjusting the spacing of the mounting rods 304 to accommodate the fitted forming pulley 305. The fixing rod 502 is disassembled via a threaded rod and threaded hole, and a suitable fixing rod 502 is replaced. The threaded rod connected to the replaced fixing rod 502 is threadedly connected to the threaded hole of the moving block 501. The turntable is disassembled via a connecting flange, and the turntable drives the disassembly of its components, allowing for the replacement of the suitable turntable. Metal dust generated during the helical spring forming process is drawn into the filter bag 403. The filtered air is discharged, while the dust remains inside the filter bag 403. Regular cleaning of the filter bag 403 by the operator effectively reduces dust pollution, improves the working environment, avoids impacting worker health, and enhances the use of helical spring processing tooling. Content not described in detail in this specification belongs to existing technology known to those skilled in the art.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
