Description

Technical Field

[0001] The invention relates to the technical field of spoke cutting, and in particular to a spoke cutting device. Background Art

[0002] Spokes are important components used to form a wheel set. They can be made of metal or carbon fiber materials. One end of the spoke is connected to the hub of the wheel set, and the other end is connected to the rim of the wheel set. The three work together to form a usable wheel set. Spokes are generally in the shape of thin strips. After connecting the hub and the rim, they can support the rim to keep it in the correct position. At the same time, they withstand forces from all directions during riding, including the impact force of the ground and the centripetal force during riding. When preparing spokes, they are generally molded by mold compression. The two ends of the spokes in the length direction will extend outward for a distance. The length of the spokes needs to be precisely controlled, so it is necessary to cut a part of the two ends of the spokes so that the length of the spokes meets the requirements. At present, electric saw tools are generally used to manually cut the spokes. The usual workflow is to place the spokes flat on the workbench of the electric saw, and align the saw blade with the marking points according to the pre-set marking points on the spokes for cutting. This cutting method is inefficient, and the manual control of the saw blade on the spoke cutting position has a large error. Summary of the invention

[0017] Technical solution thirteen based on technical solution one: also includes a storage bin, which is fixedly connected to the frame and is used to store spokes to be cut.

[0018] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0019] Technical solution 1 provides a spoke cutting device, which includes a frame, a spoke jig and a cutting assembly; wherein the spoke jig includes a rotating base and a jig motor, the jig motor can drive the rotating base to rotate around a first axis, a spoke fixing portion is provided on the rotating base, the spokes to be cut can be fixed in the spoke fixing portion, and rotate around the first axis with the rotating base; the cutting assembly includes two cutting devices, the two cutting devices are arranged along a first direction, and the cutting blades of the two are respectively located on both sides of the rotating base, wherein the cutting blades are at The projection plane perpendicular to the first direction overlaps with the spoke fixing part; through the structural design that the cutting blade overlaps with the spoke fixing part, when the spokes are fixed to the spoke fixing part and the rotating base is driven by the jig motor to rotate, the two ends of the spokes in the spoke fixing part will pass through the position where the cutting blades are located and be cut by the cutting blades; the relative positions of the two cutting blades and the spoke fixing part can be predetermined, and the relative positions of the two cutting blades and the spoke fixing part will not change during the cutting process, so spokes with a desired length can be obtained repeatedly.

[0020] The spoke cutting equipment provided by the present technical solution fixes the spokes to the spoke fixing part of the rotating base, and makes the spoke fixing part rotate with the rotating base, so that the spokes can pass through the position where the cutting blade is located in the cutting device, thereby cutting off the excess part of the spoke by the cutting blade, thereby completing the automatic cutting of the spokes; the spoke cutting equipment has the advantages of high efficiency, accurate cutting position and small cutting error.

[0021] In the second technical solution, the spoke fixing part is arranged on the circumferential edge of the rotating base, and the spoke fixing part is in the shape of a groove with a notch. When fixing the spokes, the spokes can be conveniently embedded into the groove-shaped spoke fixing part from the outer peripheral position of the rotating base. Moreover, since the spokes are fixed by embedding, the position where the spokes need to be cut can be intuitively determined before embedding. At the same time, after the cutting is completed, the cut spokes can also be conveniently removed from the spoke fixing part.

[0022] In the third technical solution, a limit assembly is provided, and the limit assembly includes two limit devices, and the limit device includes a baffle, and a limit surface is provided on the baffle. Since the spoke fixing part is provided in a groove shape, although this structure facilitates the embedding and fixing of the spoke into the spoke fixing part, when the cutting device is used to cut the spoke end, the cutting blade contacts the spoke, which causes the spoke to jump, and then the problem of uneven cutting surface occurs. For this reason, in the present technical solution, after the spoke enters the range of the limit surface, the limit surface will limit the spoke in the first direction. The limit here can be that the limit surface is in direct contact with the spoke, or there is a very small gap between the limit surface and the spoke. In both cases, the limit surface can prevent the spoke from jumping to a large extent during the cutting process, thereby effectively improving the problem of uneven cutting surface.

[0023] In technical solution four, the limiting device can move back and forth along the first direction, so as to facilitate adjustment of the limiting position according to the required length of the spoke.

[0024] In technical solution five, the limiting assembly includes a first sliding device, which can drive the first mounting plate to move along the first direction through the first driving cylinder. The limiting device is fixedly connected to the first mounting plate, so that the limiting device can reciprocate along the first direction.

[0025] In technical solution six, the spoke fixing part is also provided with a main body section and a tightening section, which can be adapted to spokes with a specific shape. Through the position of the tightening section on the spoke fixing part, when the spoke is correctly embedded and fixed in the spoke fixing part, the length of the part to be cut on the spoke to be cut can be directly limited.

[0026] In the seventh technical solution, the rotating base includes two rotating seats, the positions of which can be adjusted in the first direction, and a part of the spoke fixing part is formed on each of the two rotating seats, and the two rotating seats form a complete spoke fixing part after cooperation; in this way, when adjusting the required length of the cut spokes, the distance between the spoke fixing parts of the two parts can be changed by adjusting the position of the rotating seat in the first direction, thereby adjusting the total length of the complete spoke fixing part formed by cooperation. Moreover, when the spokes are cut, the parts of the spoke fixing seats exposed at both ends are very small, but since a gap can be formed between the two rotating seats, the cut spokes can be easily removed from the middle position, thereby realizing efficient cutting of the cut spokes.

[0027] In technical solution eight, the rotating seat body includes a rotating disk and a spoke fixing seat. The rotating disk can adopt a flat disk structure, which is convenient for the rotating base to be driven to rotate by the fixture motor. The spoke fixing seat is convenient for setting the spoke fixing part, and the size of the spoke fixing seat in the first direction may not be consistent with the size of the rotating disk in the first direction. A longer spoke fixing seat can make the set spoke fixing part have a longer length, ensuring that the spoke has a sufficiently long part to form contact with the spoke fixing part after being embedded and fixed to the spoke fixing part, thereby improving the stability of the spoke during the cutting process.

[0028] In technical solution nine, a blanking plate is provided, which extends obliquely and is provided with a blanking protrusion. During the rotation of the rotating base, the cut spokes will pass through the blanking protrusion, and the blanking protrusion will apply force to the middle position of the cut spokes and pry the cut spokes out of the spoke fixing part. The spokes that are separated from the spoke fixing part will leave along the blanking plate. At this time, a material frame can be arranged at an appropriate position to collect the cut spokes.

[0029] In technical solution ten, the cutting device in the cutting assembly can reciprocate along the first direction, so as to adjust the cutting position according to the required length of the spoke.

[0030] In technical solution eleven, the cutting assembly includes a second sliding device, which can drive the second mounting plate to move along the first direction through a second driving cylinder. The cutting device is fixed to the second mounting plate, so that the cutting device can reciprocate along the first direction.

[0031] In the twelfth technical solution, an open waste opening is provided at the bottom of the cutting frame of the frame, and the cut waste can be discharged from the cutting frame through the waste opening.

[0032] In the technical solution thirteen, a storage bin is also provided, and the spokes to be cut can be stored in the storage bin first, so as to facilitate the loading of the spoke jig. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Example

[0052] The embodiment of the present invention relates to a spoke cutting device, which is used to cut the excess length of a semi-finished spoke with a long length so that the length of the cut spoke meets the use requirements. The spoke can be made of metal or carbon fiber. In this embodiment, the spoke made of carbon fiber is used as an example for description.

[0053] Reference Figure 1The spoke cutting device involved in this embodiment includes a frame 10, a spoke fixture 20, a cutting assembly 30, a limiting assembly 40, a blanking plate 51, a storage bin 52 and an electric control box 53.

[0054] Reference Figure 1 The frame 10 includes a base 11, a cutting frame 12, a protective baffle 13, a fixture bracket 14, a cutting bracket 15, a limit bracket 16 and a main bracket 17. The base 11 includes four legs, and an adjustment seat for adjusting the height of the base 11 is provided at the bottom of the legs. The cutting frame 12 is fixedly arranged on the top of the base 11, and the cutting frame 12 is set as a box-shaped structure with a bottom wall and side walls enclosed on the surrounding side. An open waste opening 121 is provided on the bottom wall of the cutting frame 12. Figure 2 The bottom of the cutting frame 12 is also provided with a waste trough 122 extending obliquely backward and downward. The top of the waste trough 122 is connected to the waste port 121. A waste collection box can be arranged below the waste trough 122. The cut waste enters the waste trough 122 through the waste port 121, and then is guided into the waste collection box through the waste trough 122 to complete the collection of the waste. A protective baffle 13 fixed to the base 11 is also arranged on the circumferential outer side of the cutting frame 12. The height of the protective baffle 13 is higher than the height of the side wall of the cutting frame 12, and it can roughly block the spoke jig 20 on the circumferential side, and the protective baffle 13 is open on the front side. A storage bin 52 is fixedly connected to the front side of the base 11. The storage bin 52 is a flat box-shaped component, and the chamber inside it can be used to store the spokes to be cut. The spokes to be cut can be conveniently taken from the storage bin 52 when loading. The jig bracket 14, the cutting bracket 15, the limiting bracket 16 and the main bracket 17 are described together when the spoke jig 20, the cutting assembly 30 and the limiting assembly 40 are introduced below. The electric control box 53 is installed at the rear side of the base 11, and is used to control the electrical components in the spoke jig 20, the cutting assembly 30 and the limiting assembly 40, such as cylinders, motors, etc.

[0055] Reference Figure 1 and Figure 3 The spoke jig 20 includes a rotating base 21 and a jig motor 22; the rotating base 21 is rotatably mounted on the frame 10 around a first axis in a first direction, and is provided with at least one spoke fixing portion 23; the jig motor 22 is transmission-connected with the rotating base 21 to drive the rotating base 21 to rotate; the spoke fixing portion 23 extends along the first direction and has two ends open so that the spokes can be fixedly installed and the two ends of the spokes can extend out of the spoke fixing portion 23; the position of the spoke fixing portion 23 on the rotating base 21 is configured to be suitable for rotating around the first axis with the rotating base 21.

[0056] The spoke fixing portion 23 is arranged at the circumferential edge of the rotating base 21 relative to the first axis, and is in the shape of a groove with a notch 234 for the spoke to be inserted and fixed, and the notch 234 faces outward relative to the first axis and is perpendicular to the first axis. The spoke fixing portion 23 includes a main body section 231 located in the middle and tightening sections 232 located at both ends along the first direction; the width of the tightening section 232 is smaller than the width of the main body section 231. The rotating base 21 includes two rotating seats 211 arranged along the first direction, and the rotating seats 211 are slidably fixed to the frame 10 along the first direction; the spoke fixing portion 23 is arranged on the two rotating seats 211, and its two ends in the first direction are respectively located on the two rotating seats 211. The rotating seat body 211 includes a rotating disk 212 and a plurality of spoke fixing seats 213; each of the spoke fixing seats 213 is fixedly arranged and installed on the circumferential edge of the rotating disk 212 along the circumferential direction relative to the first axis; in the two rotating seat bodies 211, each of the spoke fixing seats 213 located on one of the rotating disks 212 corresponds one to one with each of the spoke fixing seats 213 on the other rotating disk 212, and a portion of the spoke fixing portion 23 is provided on the two corresponding spoke fixing seats 213 to cooperate in forming a complete spoke fixing portion 23 in the first direction.

[0057] Specifically, refer to Figure 3 and Figure 4 , both show the structure of the spoke jig 20. In the middle position of the cutting frame 12 of the frame 10, the jig bracket 14 is fixed to the bottom wall of the cutting frame 12 by bolts, and its position corresponds to the position of the waste port 121 on the cutting frame 12. The jig bracket 14 includes two arms extending in the vertical direction, and the two arms extend in the left and right directions. It should be understood that the first direction referred to in this specification and the claims is the left and right direction in this embodiment. A rotating bearing and a rotating shaft are also provided on the two arms of the jig bracket 14, and a rotating base 21 is provided through the rotating bearing and the rotating shaft. A jig motor 22 is fixedly connected to one of the arms, and the output end of the jig motor 22 is connected to the rotating shaft, and then the rotating base 21 is driven to rotate through the rotating shaft. The extension direction of the rotating shaft is the first direction, and the rotating axis of the rotating base 21 is the first axis, which also extends in the first direction. The jig motor 22 is also electrically connected to the electric control box 53 to control the operation of the jig motor 22 through the electric control box 53.

[0058] The rotating base 21 is provided with a spoke fixing portion 23, which extends along the first direction and is open at both ends. In this embodiment, the spoke fixing portion 23 is provided at the circumferential edge of the rotating base 21 relative to the first axis, that is, it is provided at the outermost position of the rotating base 21, and the spoke fixing portion 23 is a groove-shaped structure with a notch 234. When fixing the spoke, the spoke can be conveniently embedded into the groove-shaped spoke fixing portion 23 from the outer circumference of the rotating base 21, and because the spoke is fixed in an embedded manner, the position where the spoke needs to be cut can be intuitively determined before embedding, and after the cutting is completed, the cut spoke can also be conveniently taken out from the spoke fixing portion 23. In addition, the direction of the notch 234 is perpendicular to the first axis, and in the process of embedding the spoke into the notch 234, the embedding direction of the spoke is more convenient for applying force, which can ensure that the spoke is embedded in the spoke fixing portion 23 in a correct posture.

[0059] The rotating base 21 includes two rotating seats 211 arranged along a first direction. The two rotating seats 211 are relatively independent components, and both are slidably fixed on the rotating shaft along the first direction. Specifically, a mounting ring for fixing the rotating seat 211 can be provided on the rotating shaft. The mounting ring is fixed around the rotating shaft and has a locking surface facing the rotating seat 211 corresponding thereto. The side of the rotating seat 211 contacts the locking surface, and the rotating seat 211 is locked to the threaded hole on the locking surface by a bolt passing through the first direction. The mounting ring can be fixed on the rotating shaft by a clamping method. When the position of the rotating seat 211 needs to be adjusted, the mounting ring is loosened, and the position of the mounting ring on the rotating shaft is adjusted to a predetermined position, and finally the mounting ring is re-locked to clamp the rotating shaft. Each spoke fixing portion 23 is divided into two parts, which are respectively arranged on two rotating seats 211 and correspond to each other. At this time, the two ends of the spoke fixing portion 23 in the first direction are respectively located on the two rotating seats 211. It can be understood that since the two rotating seats 211 are separated from each other, the part between the two rotating seats 211 does not belong to the scope of the spoke fixing portion 23. After the spoke is embedded in the spoke fixing portion 23, the part between the two rotating seats 211 will be in a suspended state. In this way, when adjusting the required length of the cut spoke, the distance between the two parts of the spoke fixing portion 23 can be changed by adjusting the position of the rotating seat 211 in the first direction, thereby adjusting the total length of the complete spoke fixing portion 23 formed by cooperation. In addition, when the spoke is cut, the parts of the spokes exposed from the spoke fixing seat 213 at both ends are very small, but since a gap can be formed between the two rotating seats 211, the cut spokes can be conveniently removed from the middle position, thereby realizing efficient cutting of the cut spokes.

[0060] Further, refer to Figure 3 and Figure 4Each rotating seat body 211 includes a rotating disk 212 and a plurality of spoke fixing seats 213, wherein the rotating disk 212 is a flat disk-shaped member, the center position of which coincides with the first axis, and is fixedly mounted on the rotating shaft through the above-mentioned mounting ring. At the outermost edge position of the rotating disk 212, a plurality of spoke fixing seats 213 are arranged along the circumference of the rotating disk 212, and these spoke fixing seats 213 can be evenly arranged on the circumferential edge of the rotating disk 212 according to a preset angle spacing, and the number and position of the spoke fixing seats 213 on the two rotating disks 212 correspond to each other, and at the same time, in each group of mutually corresponding spoke fixing seats 213, a part of a spoke fixing portion 23 is respectively provided on the two spoke fixing seats 213, and when the two rotating disks 212 are both mounted on the rotating shaft, the parts of the spoke fixing portions 23 on the two spoke fixing seats 213 cooperate with each other to form a complete spoke fixing portion 23. Obviously, an embedding groove for embedding a part of the spoke is provided on each spoke fixing seat 213, and the embedding grooves on the two corresponding spoke fixing seats 213 have similar structures and cooperate to form the above-mentioned spoke fixing portion 23. An end opening 233 of the spoke fixing portion 23 is formed at the end of each embedding groove facing outward, and the end opening 233 can allow the spoke to extend from the spoke fixing portion 23 after being embedded in the spoke fixing portion 23, so as to facilitate cutting the extended part so that the length of the spoke meets the requirements. The size of the spoke fixing seat 213 in the first direction may not be consistent with the size of the rotating disk 212 in the first direction. A longer spoke fixing seat 213 can make the set spoke fixing portion 23 have a longer length, ensuring that a sufficiently long portion of the spoke forms contact with the spoke fixing portion 23 after being embedded and fixed to the spoke fixing portion 23, thereby improving the stability of the spoke during the cutting process.

[0061] Among them, refer to Figure 4 Each spoke fixing portion 23 includes a body section 231 and a tightening section 232. The width of the body section 231 is greater than the width of the tightening section 232, so that it can better adapt to the spokes of corresponding shapes. By the position of the tightening section 232 on the spoke fixing portion 23, when the spoke is correctly embedded and fixed in the spoke fixing portion 23, the length of the portion to be cut on the spoke to be cut can be directly limited.

[0062] Further, refer to Figure 1 and Figure 5The cutting assembly 30 includes two cutting devices 31 mounted on the frame 10 along the first direction; the cutting blades 32 of the cutting devices 31 rotate around the second axis in the first direction; the cutting blades 32 of the two cutting devices 31 are respectively located on the outer sides of the corresponding sides of the rotating base 21 in the first direction, and the cutting blades 32 overlap with the spoke fixing portion 23 on the projection plane perpendicular to the first direction. In the cutting assembly 30, the cutting device 31 is movably mounted on the frame 10 and is suitable for reciprocating along the first direction. The cutting assembly 30 also includes two second sliding devices 33; the second sliding device 33 includes a second driving cylinder 331 and a second mounting plate 332; the second driving cylinder 331 is fixedly mounted on the frame 10, and its output end is used to drive the second mounting plate 332 to reciprocate along the second direction; the second mounting plate 332 is fixedly connected to one of the cutting devices 31.

[0063] Specifically, refer to Figure 1 and Figure 5 The frame 10 is provided with a main support 17 extending in the up-down direction. The main support 17 is located behind the spoke jig 20 and is higher than the spoke jig 20. A cutting support 15 is fixedly connected to the main support 17 by bolts. A second fixing plate 333 extending in the left-right direction is fixedly connected to the cutting support 15 by bolts. Two second sliding devices 33 arranged in the left-right direction are installed on the second fixing plate 333. Each second sliding device 33 includes a second driving cylinder 331 and a second mounting plate 332. The second driving cylinder 331 is fixedly connected to the second fixing plate 333, and its output end is fixedly connected to the second mounting plate 332. A slide rail is provided on the second fixing plate 333 in the left-right direction. The second mounting plate 332 is slidably installed in the slide rail and can reciprocate in the left-right direction on the slide rail under the drive of the second driving cylinder 331. The second driving cylinder 331 is controlled to operate by the electric control box 53. The cutting device 31 can be reciprocated along the first direction by the second sliding device 33 , so as to adjust the cutting position according to the required length of the spoke and better cooperate with the spoke jig 20 .

[0064] The cutting device 31 includes a cutting machine and a second connecting plate 311, the second connecting plate 311 is fixedly connected to the corresponding second mounting plate 332 by bolts, and the cutting machine is fixedly installed on the second connecting plate 311. The cutting machine is provided with a cutting blade 32, and the cutting blade 32 is used to cut the spokes fixed on the spoke jig 20. The two cutting devices 31 are respectively located on the left and right sides of the spoke jig 20, and the cutting blade 32 is located at the position of the spoke jig 20 closest to the corresponding side on the cutting device 31, and the cutting blade 32 overlaps with the rotation track of the spoke fixing part 23 on the projection plane perpendicular to the first direction, so that during the rotation of the rotating base 21, the spoke fixed in the spoke fixing part 23 will pass the position where the cutting blade 32 is located, so that the end of the spoke will be cut by the cutting blade 32. It is easy to understand that the cutting blade 32 here overlaps with the rotation trajectory of the spoke fixing part 23 on the projection plane, which means that after the spoke is fixed to the spoke fixing part 23, the rotation trajectory generated by the rotation of the rotating base 21 will make the spoke pass through the position of the cutting blade 32. When the spoke contacts the cutting blade 32, the rotating base 21 continues to rotate, and the spoke is subjected to the pressure of the cutting blade 32. At the same time, the cutting blade 32 rotates at high speed, thereby realizing the cutting of the spoke.

[0065] The spoke cutting device comprises a frame 10, a spoke jig 20 and a cutting assembly 30; wherein the spoke jig 20 comprises a rotating base 21 and a jig motor 22, the jig motor 22 can drive the rotating base 21 to rotate around a first axis, a spoke fixing portion 23 is provided on the rotating base 21, the spokes to be cut can be fixed in the spoke fixing portion 23, and rotate around the first axis with the rotating base 21; the cutting assembly 30 comprises two cutting devices 31, the two cutting devices 31 are arranged along a first direction, and the cutting blades 32 of the two are respectively located on both sides of the rotating base 21, wherein the cutting blades 32 are arranged vertically. The cutting blade 32 overlaps with the spoke fixing portion 23 on the projection plane in the first direction; through the structural design that the cutting blade 32 overlaps with the spoke fixing portion 23, when the spoke fixing portion 23 is fixed with the spoke and the rotating base 21 is driven by the fixture motor 22 to rotate, the two ends of the spoke in the spoke fixing portion 23 will pass through the position where the cutting blade 32 is located and be cut by the cutting blade 32; the relative positions of the two cutting blades 32 and the spoke fixing portion 23 can be predetermined, and the relative positions of the two cutting blades 32 and the spoke fixing portion 23 will not change during the cutting process, so spokes with a desired length can be obtained repeatedly. The spoke cutting device fixes the spoke to the spoke fixing portion 23 of the rotating base 21, and makes the spoke fixing portion 23 rotate with the rotating base 21, so that the spoke can pass through the position of the cutting blade 32 in the cutting device 31, so that the excess part of the spoke is cut off by the cutting blade 32, thereby completing the automatic cutting of the spoke; the spoke cutting device has the advantages of high efficiency, accurate cutting position and small cutting error.

[0066] Further, refer to Figure 1 and Figure 6 The spoke cutting device further comprises a limiting assembly 40, which comprises two limiting devices 41 mounted on the frame 10 along the first direction; the limiting device 41 comprises a stopper 42, and the stoppers 42 of the two limiting devices 41 are respectively located on the outer sides of the corresponding sides of the rotating base 21 in the first direction; the stopper 42 is provided with a limiting surface 43 which is adapted to the rotation trajectory of the spoke fixing portion 23 and is in an arc shape on the projection surface, the position of the limiting surface 43 corresponds to the cutting blade 32 located on the same side of the rotating base 21, and is configured to limit the spoke located in the spoke fixing portion 23 in the direction pointing to the first axis through the limiting surface 43 when the spoke fixing portion 23 rotates to the position corresponding to the cutting blade 32. In the limiting assembly 40, the limiting device 41 is movably mounted on the frame 10 and is suitable for reciprocating along the first direction. The limiting assembly 40 also includes two first sliding devices 44; the first sliding device 44 includes a first driving cylinder 441 and a first mounting plate 442; the first driving cylinder 441 is fixedly mounted on the frame 10, and its output end is used to drive the first mounting plate 442 to reciprocate along the first direction; the first mounting plate 442 is fixedly connected to one of the limiting devices 41.

[0067] Specifically, refer to Figure 6 , a limit bracket 16 is also fixedly provided on the main bracket 17 by bolts, and a first fixing plate 443 extending in the left-right direction is fixedly provided on the limit bracket 16 by bolts, and the first fixing plate 443 is located behind the second fixing plate 333. Two first sliding devices 44 arranged in the left-right direction are installed on the first fixing plate 443, and each first sliding device 44 includes a first driving cylinder 441 and a first mounting plate 442. The first driving cylinder 441 is fixedly provided on the first fixing plate 443, and its output end is fixedly provided on the first mounting plate 442. A slide rail is provided on the first fixing plate 443 in the left-right direction, and the first mounting plate 442 is slidably installed in the slide rail, and can reciprocate in the left-right direction on the slide rail under the drive of the first driving cylinder 441. The operation of the first driving cylinder 441 is controlled by the electric control box 53. The first sliding device 44 can be used to reciprocate the limiting device 41 in the first direction, so as to adjust the position of the limiting device 41 according to the required length of the spoke and better cooperate with the spoke fixture 20 .

[0068] The limiting device 41 includes an arc-shaped stopper bar 42, and the lower surface of the stopper bar 42 forms an arc-shaped limiting surface 43. The position and shape of the limiting surface 43 just correspond to the rotation trajectory of the spoke fixing portion 23 in the spoke fixture 20. When the rotating base 21 rotates, the portion of the spoke exposed from the spoke fixing seat 213 will be limited by the limiting surface 43. Specifically, since the spoke fixing portion 23 is configured as a groove, although this structure facilitates the embedding and fixing of the spoke into the spoke fixing portion 23, when the cutting device 31 is used to cut the spoke end, the cutting blade 32 contacts the spoke, which will cause the spoke to jump, and then the problem of uneven cutting surface will occur. To this end, in the present technical solution, after the spoke enters the range of the limiting surface 43, the limiting surface 43 will limit the spoke in the first direction. The limitation here can be that the limiting surface 43 is in direct contact with the spoke, or there can be a very small gap between the limiting surface 43 and the spoke. In both cases, the limiting surface 43 can prevent the spoke from jumping to a large extent during the cutting process, thereby effectively improving the problem of uneven cutting surface.

[0069] In addition, refer to Figure 1 and Figure 2 The spoke cutting device further comprises a blanking plate 51, which is fixedly mounted on the frame 10 and extends from top to bottom in an inclined manner away from the rotating base 21. The blanking plate 51 is located downstream of the cutting device 31 in the rotating direction of the rotating base 21, and a blanking protrusion 511 extending into between the two rotating base bodies 211 of the rotating base 21 is provided at its upper end. During the rotation of the rotating base 21, the cut spokes will pass through the blanking protrusion 511, which will apply force to the middle position of the cut spokes and pry the cut spokes from the spoke fixing portion 23. The spokes separated from the spoke fixing portion 23 will leave along the blanking plate 51. At this time, a material frame can be arranged at an appropriate position to collect the cut spokes.
