[0030] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below with reference to the drawings and examples.

[0031] This utility model provides a snap ring forming machine, which is used to cut steel wire strips and then extrude the cut portions into snap rings. The cross-sectional shape of the steel wire strip is not limited, such as square or circular; in this embodiment, a square cross-section of the steel wire strip is used as an example for description.

[0032] Please see Figure 1 and Figure 2 The snap ring forming machine includes a base 10, a lower forming mold 20, an upper forming mold 30, and a forming rod 40.

[0033] The base 10 includes a base plate 11 and a side plate 12 connected to the base plate 11. The base plate 11 is used to place on a table, the ground, or other supporting surface. The side plate 12 is arranged perpendicular to the base plate 11 and has a mounting surface. For ease of description, in the following embodiments, leftward is the first direction, downward is the second direction, and forward is the third direction, wherein the mounting surface faces the third direction.

[0034] The lower forming mold 20 includes a first module 21 and a second module 22, both connected to the mounting surface of the side plate 12. The first module 21 is located to the right of the second module 22, and the two are spaced apart. The first module 21 has a conveying hole for the steel wire strip 90 to pass through. The second module 22 is used for the end of the steel wire strip 90 passing through the conveying hole to abut against it. A working area is formed between the first module 21 and the second module 22. The steel wire strip 90 passes through the conveying hole from right to left, and its left end abuts against the second module 22.

[0035] The forming rod 40 is connected to the side plate 12. The forming rod 40 is located in the working area and below the wire strip 90. The central axis of the forming rod 40 can extend in the front-back direction. The cross-sectional shape of the forming rod 40 can be set according to the shape of the bending area of ​​the retaining spring to be formed, and is generally set to be circular.

[0036] The upper forming die 30 has a cutting section 30a, a first forming section 30b, and a second forming section 30c, which are arranged sequentially from right to left. The cutting section 30a can be formed by sharp edges machined from the upper forming die 30, or it can be a separately added cutting tool; there is no limitation here. The first forming section 30b and the second forming section 30c are located on the left and right sides of the forming rod 40, respectively. The upper forming die 30 can move vertically between a starting position and a forming position, with the starting position located above the forming position. Please refer to... Figure 3When the forming upper die 30 moves from the starting position to the forming position, the cutting part 30a can cut the steel wire material belt 90 in the working area, so that the cut part forms the to-be-extruded material belt 91. Since the cutting part 30a is located at the right side of the first forming part 30b, the middle part of the to-be-extruded material belt 91 can be placed on the forming rod 40 downwardly. The forming upper die 30 continues to descend, and the first forming part 30b and the second forming part 30c can extrude the two end parts of the to-be-extruded material belt 91 downwardly, so that the to-be-extruded material belt 91 is bent toward the second direction due to the support of the forming rod 40, and finally forms a U-shaped clasp spring, which is referred to as a formed clasp spring 91a. After forming, the forming upper die 30 can be reset to the starting position.

[0037] The clasp spring forming machine cuts the part of the steel wire material belt 90 in the working area by the cutting part 30a of the forming upper die 30, so that the cut part forms the to-be-extruded material belt 91. The left and right two end parts of the to-be-extruded material belt 91 can be bent downwardly by the pressing of the first forming part 30b and the second forming part 30c and the support of the forming rod 40, so as to form an inverted U-shaped clasp spring. In this way, the clasp spring forming machine can realize the cutting and bending of the steel wire material belt 90 synchronously by the setting of the forming upper die 30, reduces the processing procedures, shortens the production line, and reduces the processing cost.

[0038] Please refer to Figure 1 Optionally, the forming upper die 30 can be driven by a forming driving member 31. The forming driving member 31 can be an electric punch press. The electric punch press is located above the forming upper die 30 and is connected to the forming upper die 30 through a connecting handle 32. The forming driving member 31 can drive the forming upper die 30 to move between the starting position and the forming position. The base 10 can further include a support table 13. The bottom plate 11 is connected to the support table 13. The electric punch press is connected to the support table 13 through a support rod 33. In other embodiments, the up-and-down movement of the forming upper die 30 can also be manually operated, which is not limited here.

[0039] Optionally, the forming rod 40 can always support the steel wire material belt 90 when the forming upper die 30 is in the starting position, so as to avoid the to-be-extruded material belt 91 from sliding downwardly when the steel wire material belt 90 is cut into the to-be-extruded material belt 91.

[0040] Optionally, the cutting part 30a of the forming upper die 30 can be close to the side of the first module 21 facing the second module 22, so as to facilitate the cutting of the steel wire material belt 90.

[0041] Please refer to Figure 1Optionally, the upper forming die 30 is slidingly connected to the lower forming die 20 to guide the moving path of the upper forming die 30. The first module 21 and the second module 22 can be provided with sliding grooves 201, and the upper forming die 30 is slidingly connected to the sliding grooves 201 on the first module 21 and the second module 22. When the upper forming die 30 is at the starting position, the upper forming die 30 is also slidingly connected to the lower forming die 20. In other embodiments, when the upper forming die 30 is at the starting position, the upper forming die 30 can also be spaced apart from the lower forming die 20.

[0042] Please refer to Figure 2 Optionally, the upper forming die 30 is provided with a forming groove 301, the opening of the forming groove 301 faces downward, the forming groove 301 is provided through in the front-rear direction, the forming groove 301 avoids the forming rod 40, and the two groove side walls of the forming groove 301 are respectively located on the left and right sides, and the groove side walls on the left and right sides can respectively form a first forming part 30b and a second forming part 30c. The first forming part 30b and the second forming part 30c are arranged at an included angle to form an open groove. The lower end of the first forming part 30b and the right side of the upper forming die 30 form a cutting part 30a. When the upper forming die 30 moves from the starting position to the forming position, the cutting part 30a first cuts the steel wire strip 90 into a to-be-extruded strip 91, and then the lower end of the first forming part 30b extrudes the right end of the to-be-extruded strip 91, and the lower end of the second forming part 30c extrudes the left end of the to-be-extruded strip 91. The left end and the right end of the to-be-extruded strip 91 are synchronously bent downward. With the downward movement of the upper forming die 30, the contact area between the first forming part 30b and the second forming part 30c and the to-be-extruded strip 91 gradually increases, until the final forming of the snap spring 91a, and the left and right arms of the formed snap spring are respectively attached to the wall surface of the second forming part 30c and the wall surface of the first forming part 30b. The open arrangement of the forming groove 301 can facilitate the separation of the formed snap spring 91a from the upper forming die 30 under the action of gravity.

[0043] In other embodiments, the groove side walls of the forming groove 301 can also be circumferentially closed, which is not limited here.

[0044] Please refer to Figure 1 and Figure 2In some embodiments, the side plate 12 has a pull hole, and the forming rod 40 is slidably connected to the pull hole and can move along the axial direction of the pull hole. The forming rod 40 can move between a clearance position and a limit position in the front-back direction, with the limit position located in front of the clearance position. When the snap ring needs to be formed, the forming rod 40 can be moved to the limit position. At this time, the forming rod 40 is located below the steel wire strip 90 to support the cut and extruded strip 91. After the snap ring is formed, the forming rod 40 can be moved from the limit position to the clearance position. When the forming rod 40 is in the clearance position, the forming rod 40 and the steel wire strip 90 are offset in the vertical direction so that the formed snap ring can fall under the action of gravity, realizing automatic feeding.

[0045] Optionally, the snap ring forming machine may also include a pull-out drive 41, which is connected to the forming rod 40 and is used to drive the forming rod 40 to move between an avoidance position and a limit position. In other embodiments, the forward and backward movement of the forming rod 40 may also be manually operated, which is not limited here.

[0046] Optionally, when the forming rod 40 is in the avoidance position, the front end face of the forming rod 40 can be flush with the mounting surface of the side plate 12.

[0047] Please see Figure 2 and Figure 3 In some embodiments, the snap ring forming machine further includes a limiting block 50, which is connected to the mounting surface of the side plate 12. The limiting block 50 is located in the working area between the first module 21 and the second module 22, and is located on the upper side of the wire strip 90. Since the wire strip 90 has a certain elasticity, the two elastic arms of the formed snap ring 91a will be tightly attached to the first forming part 30b and the second forming part 30c due to their own elastic restoring force. Therefore, when the upper forming mold 30 is reset towards the starting position, the formed snap ring 91a may move upward synchronously with the upper forming mold 30. The setting of the limiting block 50 can restrict the upward movement of the formed snap ring 91a, thereby causing the formed snap ring 91a to separate from the upper forming mold 30 when the upper forming mold 30 moves towards the starting position, thereby realizing the demolding of the formed snap ring 91a.

[0048] Optionally, the bottom of the forming groove 301 is provided with a relief groove 302, which can be used to avoid the limiting block 50, so as to prevent the upper forming mold 30 from crushing the limiting block 50.

[0049] Please see Figure 1 and Figure 2 In some embodiments, the snap ring forming machine may also include a discharge slide 70, which may be connected to the base 10 and located below the forming lower die 20. The formed snap ring 91a that falls off the forming rod 40 can be discharged through the discharge slide 70.

[0050] Please see Figure 2 In some embodiments, the first module 21 includes a first main body 211 and a first wear-resistant part 212. The first main body 211 has a first connecting hole in the left-right direction, and the first wear-resistant part 212 is inserted into the first connecting hole and has a conveying hole. The length of the first wear-resistant part 212 in the first direction is greater than the length of the first main body 211 in the first direction. The first wear-resistant part 212 can limit the steel wire strip 90 over a relatively long range to prevent the middle of the steel wire strip 90 from collapsing. The first wear-resistant part 212 can be made of a material with high hardness to prevent the movement of the steel wire strip 90 in the conveying hole from causing too much wear to the first module 21. When the wall of the conveying hole is severely worn, the first wear-resistant part 212 can be replaced for continued use without replacing the entire forming lower die 20, thus saving costs.

[0051] Please see Figure 2 In some embodiments, the second module 22 includes a second main body 221 and a second wear-resistant part 222. The second main body 221 has a second connecting hole in the left-right direction. The second wear-resistant part 222 is inserted into the second connecting hole and is used for the end of the steel wire strip 90 located in the working area to abut against it. In this way, when the second wear-resistant part 222 wears due to repeated abutment by the steel wire strip 90, only the second wear-resistant part 222 needs to be replaced, without replacing the entire forming lower mold 20, thus saving costs. The second wear-resistant part 222 can be made of a material with high hardness, and the second connecting hole can be a through hole or a blind hole, without limitation.

[0052] Please see Figure 4 In some embodiments, the snap ring forming machine further includes a detection element 80, which is used to detect whether the end of the steel wire strip 90 abuts against the second module 22. The detection element 80 includes, but is not limited to, fiber optic sensors, position sensors, infrared sensors, etc. The forming drive 31 can drive the upper forming die 30 to move from the starting position toward the forming position after the detection element 80 detects that the left end of the steel wire strip 90 abuts against the second module 22.

[0053] Optionally, the side plate 12 is provided with mounting holes. The snap ring forming machine also includes a fixing block 81, which is installed in the mounting holes. The fixing block 81 is provided with fixing holes, and the testing piece 80 is installed in the fixing holes.

[0054] Please see Figure 2In some embodiments, the snap ring forming machine further includes a material conveying mechanism 60, which includes a conveying drive 63, a drive wheel 61, and a driven wheel 62. The conveying drive 63 is connected to the drive wheel 61 and can drive the drive wheel 61 to rotate. The conveying drive 63 can be a motor. A through hole is provided on the side plate 12, and the output shaft of the motor passes through the through hole and is connected to the drive wheel 61. The drive wheel 61 and the driven wheel 62 are both located on the mounting surface side of the side plate 12. The driven wheel 62 is rotatably connected to the base 10. Specifically, the base 10 also includes a guide seat 14, a support block 15, and a pin 16 connected to the bottom plate 11. The guide seat 14 is mounted on the bottom plate 11, and the support block 15 is mounted above the guide seat 14 and has two support ears. The driven wheel 62 is located between the two support ears and is rotatably connected to the support ears through the pin 16 connected to the two support ears. The rotation axes of both the conveying wheel and the driven wheel 62 extend in the front-to-back direction. The driving wheel 61 and the driven wheel 62 together clamp the steel wire strip 90. When the conveying drive 63 drives the driving wheel 61 to rotate, the driving wheel 61 can make the steel wire strip 90 be conveyed to the left through the friction between it and the steel wire strip 90. At the same time, the driven wheel 62 also rotates as the steel wire strip 90 is conveyed.

[0055] Optionally, a limiting annular groove 621 is provided on the peripheral side of the driven wheel 62. The limiting annular groove 621 is arranged around the central axis of the driven wheel 62. The steel wire material is clamped between the peripheral side of the driving wheel 61 and the bottom surface of the limiting annular groove 621. The limiting annular groove 621 is used to restrict the movement of the steel wire strip 90 in the front-back direction, thereby realizing the stable conveying of the steel wire strip 90.

[0056] The circumferential side of the driving wheel 61 can abut against the circumferential side of the driven wheel 62, so that the driving wheel 61 can drive the driven wheel 62 to rotate synchronously.

[0057] In other embodiments, a limiting annular groove 621 may be provided on the circumferential side of the drive wheel 61, as long as it can limit the steel wire material; no restrictions are imposed here.

[0058] It should be noted that in other embodiments, the snap ring forming machine may not have a base 10, and each structural component may be set individually; no restrictions are imposed here.

[0059] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way.
