Description

Technical Field

[0001] This utility model relates to the field of wire production technology, and in particular to a structure for grinding and shaping the cross section of spring steel wire. Background Technology

[0002] After spring steel wire is made into springs, its cross-section will have a relatively sharp cut. To avoid the impact of the cross-section on its use, it needs to be shaped. Common shaping processes include grinding, extrusion, rolling, and electrochemical polishing. Among these, grinding is suitable for spring steel wires with relatively low requirements for cross-sectional precision, such as spring steel wires for shock absorbers. However, existing grinding equipment, such as the spring steel wire cross-section grinding device with announcement number CN118720890B, does not consider the safety of the grinding operation. The flying debris generated during grinding can easily cause injury to workers. Therefore, it is necessary to provide a new spring steel wire cross-section grinding and shaping structure to solve the above-mentioned technical problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a spring steel wire cross-section grinding and shaping structure.

[0004] The spring steel wire cross-section grinding and shaping structure provided by this utility model includes: a base frame, on one side of the top of the base frame a grinding motor movably connected thereto, and a grinding disc at the output end of the grinding motor;

[0005] A protective cover is provided above the top of the base frame. A support assembly is provided inside the protective cover. The support assembly includes a support frame. The support frame is rotatably disposed inside the protective cover. Cylinders are provided at the top and bottom of the inner side of the support frame, and clamping plates are provided at the opposite ends of the two cylinders.

[0006] Preferably, the bottom of the protective cover is provided with a rotating rod that is rotatably connected, and a worm gear that is fixedly connected is sleeved on one side of the outer side of the rotating rod. A worm wheel that is meshed with the outer side of the worm gear is provided, and the worm wheel is fixedly connected to the bottom of the support frame.

[0007] Preferably, the top of the support frame extends outside the protective cover and is provided with a fixedly connected protruding rod. Positioning rods are provided on both sides of the protruding rod at the top of the protective cover, and the positioning rods on both sides are staggered.

[0008] Preferably, a hydraulic cylinder and a guide telescopic rod are fixedly connected to one side of the top of the base frame, and the ends of the guide telescopic rod and the hydraulic cylinder are fixedly connected to the end of the grinding motor.

[0009] Preferably, a guide frame is mounted on the other side of the top of the base frame, and a sliding frame is slidably connected to the outside of the guide frame, with the bottom of the sliding frame fixedly connected to the top of the protective cover.

[0010] Preferably, a transparent plate is embedded in the side wall of the protective cover, and a gripping rod is provided at the end of the protective cover away from the grinding motor.

[0011] Compared with related technologies, the spring steel wire cross-section grinding and shaping structure provided by this utility model has the following beneficial effects:

[0012] After clamping and fixing the spring steel wire to be ground, the present invention can move the support frame toward the grinding disc. When the outer wall of the grinding disc abuts against the cross section of the spring steel wire, the cross section of the spring steel wire can be ground and shaped.

[0013] This invention, by rotating the support frame in the support assembly, allows for the rapid rotation of the spring steel wire after grinding one section of the spring steel wire, so that the other section of the spring steel wire faces the grinding disc for grinding, without the need for disassembly and reinstallation of the spring steel wire.

[0014] 3. During the grinding process, the protective cover located outside the support component can cover the grinding motor and grinding disc, thereby shielding and protecting the debris generated during the grinding process. This avoids the safety hazards caused by the random splashing of debris during the grinding process. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 4 The present invention provides a spring steel wire cross-section grinding and shaping structure, which includes: a base frame 1.

[0022] In the embodiments of this utility model, please refer to Figures 1 to 4 A grinding motor 2 is movably connected to one side of the top of the base frame 1. The output end of the grinding motor 2 is equipped with a grinding disc 21. A protective cover 3 is movably connected above the top of the base frame 1. A support assembly 4 is provided inside the protective cover 3. The support assembly 4 includes a support frame 41. The support frame 41 is rotatably set inside the protective cover 3. Cylinders 51 are provided at the inner top and inner bottom of the support frame 41, and clamping plates 5 are provided at the opposite ends of the two cylinders 51.

[0023] It should be noted that during use, the spring steel wire to be ground can be placed between the clamping plates 5, and the cylinder 51 can be controlled to move the clamping plates 5. When the clamping plates 5 on both sides abut against the outer wall of the spring steel wire, the spring steel wire can be clamped and fixed. Then, the support frame 41 can be moved towards the grinding disc 21. When the outer wall of the grinding disc 21 abuts against the cross section of the spring steel wire, the cross section of the spring steel wire can be ground and shaped. After grinding one cross section of the spring steel wire, the support frame 41 can be controlled to rotate to flip the spring steel wire so that the other cross section of the spring steel wire faces the grinding disc 21 and is ground and shaped. There is no need to disassemble and reinstall the spring steel wire.

[0024] In the embodiments of this utility model, please refer to Figures 1 to 4 The bottom of the protective cover 3 is provided with a rotating rod 42 that is rotatably connected. A worm gear 43 that is fixedly connected is sleeved on one side of the outer side of the rotating rod 42. A worm wheel 431 that is meshed with the outer side of the worm gear 43 is provided, and the worm wheel 431 is fixedly connected to the bottom of the support frame 41. The top of the support frame 41 extends to the outside of the protective cover 3 and is provided with a protruding rod 44 that is fixedly connected. Positioning rods 45 are provided on both sides of the protruding rod 44 at the top of the protective cover 3, and the positioning rods 45 on both sides are staggered.

[0025] It should be noted that: with the setting of positioning rod 45 and protruding rod 44, when the operator controls the support frame 41 to rotate, the support frame 41 will drive the top protruding rod 44 to move synchronously. When the outer wall of the protruding rod 44 abuts against the outer wall of positioning rod 45, the support frame 41 can be accurately controlled to rotate 180°, so that the other section of the spring steel wire can be quickly adjusted to face the grinding disc 21.

[0026] After the spring steel wire is rotated and adjusted, when the cross section of the spring steel wire abuts against the outer wall of the grinding disc 21, the self-locking characteristic between the worm gear 431 and the worm 43 can prevent the support frame 41 from rotating in the opposite direction, thus enabling the support frame 41 to provide stable support for the spring steel wire.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 4 A hydraulic cylinder 12 and a guide telescopic rod 13 are fixedly connected on one side of the top of the base frame 1, and the ends of the guide telescopic rod 13 and the hydraulic cylinder 12 are fixedly connected to the end of the grinding motor 2. A guide frame 11 is mounted on the other side of the top of the base frame 1. A sliding frame 32 is slidably connected to the outside of the guide frame 11, and the bottom of the sliding frame 32 is fixedly connected to the top of the protective cover 3. A transparent plate 31 is embedded on the side wall of the protective cover 3, and a gripping rod 33 is provided at the end of the protective cover 3 away from the grinding motor 2.

[0028] It should be noted that: by using hydraulic cylinder 12 to support grinding motor 2, during use, the operator can control the extension of hydraulic cylinder 12 according to the specifications of the spring steel wire clamped in the support component 4, thereby adjusting the distance between the outside of grinding disc 21 and the side wall of base frame 1. Therefore, when this device grinds the relatively short cross section of spring steel wire, the protective cover 3 can still be fitted outside the grinding motor 2, preventing the grinding disc 21 from not contacting the cross section of spring steel wire when the end of the protective cover 3 abuts against the side wall of base frame 1. At the same time, the protective cover 3 can also shield and protect the debris generated during grinding.

[0029] With the transparent plate 31 embedded on the side wall of the protective cover 3, it is easy for staff to see the distance between the grinding disc 21 and the cross section of the spring steel wire during use.

[0030] The working principle of the spring steel wire cross-section grinding and shaping structure provided by this utility model is as follows:

[0031] When using this device, the operator can first take out the spring steel wire and place it between the two clamping plates 5. Then, control the cylinder 51 to move the clamping plates 5. When the outer wall of the clamping plate 5 abuts against the outer wall of the spring steel wire, the clamping and fixing of the spring steel wire can be completed.

[0032] At this time, the staff can hold the grip rod 33 on the outer wall of the protective cover 3 and push the grip rod 33. At this time, the driving force can make the sliding frame 32 slide on the outer wall of the guide frame 11, thereby mobilizing the protective cover 3 and other components below to move synchronously.

[0033] During this process, the relatively large protective cover 3 can be fitted over the outside of the grinding motor 2 and the grinding disc 21. During the movement, the operator can accurately control the position of the internal spring steel wire through the transparent plate 31 on the side wall of the protective cover 3, so that the cross section of the spring steel wire can abut against the outer wall of the grinding disc 21. At this time, the rotating grinding disc 21 can grind and shape the cross section of the spring steel wire.

[0034] During the polishing process, the protective cover 3 located outside the polishing disc 21 and the polishing motor 2 can shield the debris generated during the polishing process, thereby reducing the phenomenon of debris splashing.

[0035] After grinding the current cross-section of the spring steel wire, the holding rod 33 can be driven in the opposite direction, and then the rotating rod 42 can be rotated. At this time, the rotating rod 42 will drive the worm 43 on the outer wall to rotate. The rotating worm 43 will drive the support frame 41 inside the protective cover 3 to rotate through meshing with the external worm wheel 431, thereby realizing the flipping of the spring steel wire clamped inside. While the support frame 41 is rotating, the top protrusion 44 can be driven to rotate synchronously. When the outer wall of the protrusion 44 abuts against the outer wall of another positioning rod 45, the other cross-section of the spring steel wire can be accurately adjusted to face the grinding disc 21 and ground and shaped.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
