Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring processing technology, and in particular to a cutting tool for manufacturing springs. Background Technology
[0002] The forming cutter on a spring machine is an indispensable tool in the spring manufacturing process. Its main function is to bend and shape spring wire into a predetermined shape and size. During the operation of the spring machine, the forming cutter, through contact and friction with the wire, causes it to undergo corresponding bending deformation, thereby obtaining the desired spring shape. Therefore, the design and manufacturing precision of the forming cutter directly affects the quality and performance of the spring product.
[0003] Existing spring forming cutters are usually fixed to the spring machine with bolts to maintain stable positioning. However, when the forming cutter is used with springs of high material hardness, the cutting edge will inevitably become dull after a long period of use, requiring disassembly and replacement. This makes the disassembly of the cutter troublesome. To solve the above problems, a new type of cutter for manufacturing springs is needed. Utility Model Content
[0004] The purpose of this utility model is to solve the problems raised by the prior art and to propose a tool for manufacturing springs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cutting tool for manufacturing springs includes a forming tool body, a mounting plate on one side of the forming tool body, a sliding groove on the upper surface of the forming tool body, a backing groove on the lower surface of the mounting plate, an arc-shaped surface on the surface of the forming tool body, a beveled surface on the bottom surface of the forming tool body, a semi-circular groove on the surface of the beveled surface, and a disassembly mechanism on the inner wall of the sliding groove.
[0007] Preferably, the easy-to-disassemble mechanism includes a pair of snap-fit plates slidably connected to the inner wall of the groove, the surface of the snap-fit plates being adapted to the inner wall of the undercut groove.
[0008] Furthermore, the surface of the forming blade body is provided with lightweight holes, and a pair of through holes are provided on the surface of the forming blade body. A T-shaped rod is slidably connected to the inner wall of the through hole, and one end of the T-shaped rod is fixedly connected to the surface of the snap-fit plate.
[0009] Preferably, a sleeve is fixedly connected to the surface of one of the snap-fit plates, and a sliding shaft is fixedly connected to the surface of the other snap-fit plate, wherein the surface of the sliding shaft is slidably connected to the inner wall of the sleeve.
[0010] Furthermore, the same return spring is fitted onto the surface of the sliding shaft and the sleeve, and the two ends of the return spring are respectively fixedly connected to the opposite surfaces of a pair of snap-fit plates.
[0011] Preferably, a first H-shaped shaft and a second H-shaped shaft are fixedly connected to the surface of the forming blade body, and the first H-shaped shaft and the second H-shaped shaft are installed at a 90-degree right angle.
[0012] The beneficial effects of this utility model are as follows:
[0013] When disassembling and replacing the entire forming blade body, press a pair of T-shaped rods to move a pair of snap-fit plates closer together, releasing the snap-fit plates from the snap-fit groove, thus separating and disassembling the forming blade body from the mounting plate. The advantage of doing this is that the forming blade body can be quickly replaced and disassembled after it wears down. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1-4A cutting tool for manufacturing springs includes a forming blade body 1, a mounting plate 2 on one side of the forming blade body 1, a sliding groove 6 on the upper surface of the forming blade body 1, an undercut groove 3 on the lower surface of the mounting plate 2, an arc-shaped surface 12 on the surface of the forming blade body 1, a beveled surface 13 on the bottom surface of the forming blade body 1, a semi-circular groove 14 on the surface of the beveled surface 13, and a disassembly mechanism on the inner wall of the sliding groove 6.
[0021] The forming blade body 1 is installed and fixed by setting the mounting plate 2. The sliding groove 6 provides space for the movement of the snap-fit plate 4. The snap-fit groove 3 provides space for the snap-fit plate 4 to snap and position. The beveled surface 13 allows the forming blade body 1 to cut the spring. The semi-circular groove 14 guides the spring to move when feeding. The easy disassembly mechanism allows the forming blade body 1 to be easily and quickly removed from the mounting plate 2 for replacement.
[0022] In this utility model, reference Figure 2 The disassembly mechanism includes a pair of snap-fit plates 4 that are slidably connected to the inner wall of the slide groove 6, and the surface of the snap-fit plates 4 is adapted to the inner wall of the inverted groove 3.
[0023] By setting a pair of snap-fit plates 4, which are snapped into the undercut groove 3, the stability of the forming blade body 1 after installation is maintained.
[0024] In this utility model, reference Figure 2 The surface of the forming blade body 1 is provided with a lightweight hole 7 and a pair of through holes 11. A T-shaped rod 5 is slidably connected to the inner wall of the through hole 11, and one end of the T-shaped rod 5 is fixedly connected to the surface of the snap-fit plate 4.
[0025] By setting through holes 11, T-shaped rod 5 is given sliding clearance space. By setting T-shaped rod 5, it can be driven to apply pressure to the surface of snap-fit plate 4, pushing a pair of snap-fit plates 4 closer to each other.
[0026] In this utility model, reference Figure 2 One of the snap-fit plates 4 has a sleeve 8 fixedly connected to its surface, and the other snap-fit plate 4 has a sliding shaft 10 fixedly connected to its surface. The surface of the sliding shaft 10 is slidably connected to the inner wall of the sleeve 8.
[0027] By setting the sleeve 8, the sliding stability of the slide shaft 10 is maintained.
[0028] In this utility model, reference Figure 2 The same return spring 9 is fitted on the surface of the slide shaft 10 and the sleeve 8. The two ends of the return spring 9 are fixedly connected to the opposite surfaces of a pair of snap-fit plates 4.
[0029] By setting a reset spring 9, a pair of snap-fit plates 4 are driven to move away from each other and snap-fit into the inverted groove 3 for positioning.
[0030] In this utility model, reference Figure 4 The surface of the forming blade body 1 is fixedly connected with a first H-shaped shaft 15 and a second H-shaped shaft 16, which are installed at a 90-degree right angle.
[0031] By setting the first H-shaped shaft 15 and the second H-shaped shaft 16, the spring can be coiled during the spring feeding process, thereby producing a spiral spring.
[0032] Working principle: When the forming blade body 1 is in normal use, the spring surface can be quickly cut off through the beveled surface 13 to make it fall into the material. The spring is guided to move during feeding through the semi-circular groove 14. The spring can be coiled during feeding through the first H-shaped shaft 15 and the second H-shaped shaft 16 to produce a spiral spring. When the forming blade body 1 is disassembled and replaced, a pair of T-shaped rods 5 are pressed to drive a pair of snap-fit plates 4 to move closer to each other, releasing the snap-fit state of the snap-fit plates 4 in the snap-fit groove 3. At this time, the sliding shaft 10 is driven to slide into the sleeve 8, and the compression reset spring 9 becomes shorter, realizing the separation and disassembly of the forming blade body 1 and the mounting plate 2.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
