Description

Technical Field

[0001] This invention relates to the field of alloy rod chamfering technology, specifically to a device for chamfering the bottom of a silver-copper-zinc brazing alloy rod. Background Technology

[0002] In the production process of alloy rods, molten metal is poured into the shape of alloy rods through a casting platform. After the alloy rods are formed, they are separated from the mold to complete the demolding. Subsequently, a chamfering operation is required to remove the burrs formed on the bottom of the alloy rods after casting.

[0003] However, traditional post-processing techniques for alloy bars primarily rely on manual removal of burrs and flash from the bottom. This method is inefficient and makes it difficult to control the quality of the finished product. Furthermore, due to customer demands for customized alloy bar diameters, casting processes often produce alloy bars of varying diameters. However, existing alloy bar chamfering devices are only compatible with processing products of a single diameter, making it difficult to handle chamfering operations on alloy bars of different diameters; thus, they suffer from poor applicability. Summary of the Invention

[0004] The purpose of this invention is to improve and innovate upon the shortcomings and problems existing in the prior art, and to provide a bottom chamfering device for silver-copper-zinc brazing alloy rods.

[0005] A bottom chamfering device for a silver-copper-zinc brazing filler metal rod includes:

[0006] The material support mechanism includes a large bar support bracket and a small bar support bracket. The large bar support bracket is used to stably support the large diameter alloy bar, and the small bar support bracket is used to stably support the small diameter alloy bar.

[0007] The pressing mechanism includes a large bar pressing bracket and a small bar pressing bracket. The large bar pressing bracket is used to press the large diameter alloy bar, and the small bar pressing bracket is used to press the small diameter alloy bar.

[0008] A positioning mechanism is used to position the bottom of a large-diameter alloy rod or a small-diameter alloy rod, so that it moves to a preset position.

[0009] A cutting mechanism is used to chamfer the bottom of a large-diameter or small-diameter alloy bar to remove burrs and rough edges.

[0010] A transfer mechanism is used to transfer a large-diameter alloy bar or a small-diameter alloy bar that has completed the positioning operation from the receiving station to the cutting station.

[0011] A further embodiment includes a cutting mechanism comprising a cutter head with a cutting head for cutting large-diameter or small-diameter alloy bars, the cutter head being driven to rotate by a first motor; the cutting mechanism also includes a first electric telescopic rod for driving the cutter head to move closer to or away from the bottom of the large-diameter or small-diameter alloy bar.

[0012] A further option is that the large bar pressing bracket and the small bar pressing bracket are spaced apart along the transfer direction corresponding to the transfer from the receiving station to the cutting station;

[0013] The large bar support bracket and the small bar support bracket are also spaced apart along the transfer direction corresponding to the transfer from the receiving station to the cutting station;

[0014] The number of cutter discs is set to two, and the two cutter discs are also spaced apart along the transfer direction corresponding to the transfer from the receiving station to the cutting station.

[0015] A further embodiment is that the material support mechanism also includes a workpiece reciprocating base plate, the large bar support bracket is installed on the workpiece reciprocating base plate, and a second cylinder is also installed on the workpiece reciprocating base plate. The telescopic end of the second cylinder is connected to the small bar support bracket, and the center planes of the large bar support bracket and the small bar support bracket coincide.

[0016] A further embodiment is that the pressing mechanism includes a pressing base plate, the large bar pressing bracket is installed on the pressing base plate, and a first cylinder is also installed on the pressing base plate. The telescopic end of the first cylinder is connected to the small bar pressing bracket, and the center planes of the large bar pressing bracket and the small bar pressing bracket coincide.

[0017] A further embodiment is that the cutter head is mounted on a fixed base, and a lead screw is rotatably connected to the cutter disc. The lead screw extends along the diameter or radius of the cutter disc and is used to drive the fixed base to move along its axial direction.

[0018] A further embodiment is that the cutter head has a groove inside, the lead screw is disposed in the groove, and the top wall of the groove is connected to the external environment through a through groove; the middle part of the lead screw passes through the sliding seat and is threadedly connected to it, and the sliding seat is connected to the fixed seat through a connecting block; a first limiting groove is also provided on the top wall of the groove, and a partition is slidably fitted in the first limiting groove on both sides of the connecting block, and the end of the partition away from the connecting block is connected to the inner wall of the first limiting groove through a first spring.

[0019] A further embodiment is that the positioning mechanism includes a top rod and a limiting rod respectively disposed on both sides of the large rod support bracket and / or the small rod support bracket. The top rod abuts against the top of the large-diameter alloy rod or the small-diameter alloy rod under the action of the third electric telescopic rod; the limiting rod abuts against the bottom of the large-diameter alloy rod or the small-diameter alloy rod under the action of the fourth electric telescopic rod.

[0020] A further embodiment involves fixing a fixed disk at the end of the cutter head spindle of each of the two cutter heads furthest from the cutter head. The fixed disk is slidably fitted with a transmission disk through a second limiting groove, and the bottom wall of the second limiting groove is connected to the transmission disk via a second spring. The outer surface of the transmission disk has several protrusions arranged in a ring array. A second gear is provided on the side of the transmission disk furthest from the cutter head spindle, and the axle of the second gear is rotatably connected to a second bearing seat. Several wedge-shaped blocks that mate with the protrusions are arranged in a ring array on the second gear, and the inclined surfaces of the wedge-shaped blocks on the second gears corresponding to the two cutter heads face opposite directions. The first motor has forward and reverse rotation functions, and the output end of the first motor is fixedly connected to a first gear that meshes with the two second gears.

[0021] A further option is to provide a receiving chute and an inclined guide plate directly below the cutting mechanism.

[0022] Compared with the prior art, the beneficial effects of the present invention are: (1) By setting up a large rod support bracket and a small rod support bracket, as well as a large rod pressing bracket and a small rod pressing bracket, corresponding to the large diameter alloy rod and the small diameter alloy rod, the present invention enables the material support mechanism to stably support both the large diameter alloy rod and the small diameter alloy rod; while the pressing mechanism can press both the large diameter alloy rod and the small diameter alloy rod; thereby enabling the alloy rod chamfering machine device of this application to be compatible with the chamfering operation of both large diameter alloy rods and small diameter alloy rods;

[0023] (2) The positioning mechanism of the present invention facilitates the positioning of the bottom of the alloy rod by means of the cooperation of the third electric telescopic rod, the top rod, the fourth electric telescopic rod and the limiting rod, so as to ensure that the cutting mechanism can be chamfer at the same position every time.

[0024] (3) The present invention drives the small rod support bracket to move up and down through the second cylinder, so that when the center planes of the large rod support bracket and the small rod support bracket coincide, the small rod support bracket will not obstruct the large diameter alloy rod from being placed on the large rod support bracket; the small rod support bracket can also stably support the small diameter alloy rod and ensure that the central axis of the small diameter alloy rod placed on the material support mechanism coincides with that of the large diameter alloy rod.

[0025] (4) In this invention, the small rod pressing bracket moves up and down by the first cylinder, so that when the center planes of the large rod pressing bracket and the small rod pressing bracket coincide, the small rod pressing bracket will not obstruct the large rod pressing bracket from fixing the large diameter alloy rod; the small rod pressing bracket can also stably fix the small diameter alloy rod.

[0026] (5) By rotating the lead screw, the fixed seat can be easily moved along its axial direction, thereby adjusting the position of the cutter head on the cutter head to correspond to the size of the alloy rod; by setting the partition, it is kept in close contact with the connecting block, so that the metal chips generated during the cutting process will not fall onto the lead screw through the through groove, thus not affecting the transmission cooperation between the lead screw and the sliding seat.

[0027] (6) With the cooperation of the first gear, the second gear, the wedge block, the transmission disk, the protrusion, the fixed disk, the second limiting groove, the second spring and the first motor, the present invention can flexibly select to drive the cutter head and cutter head spindle corresponding to the small diameter alloy bar or the cutter head and cutter head spindle corresponding to the large diameter alloy bar to rotate at high speed by controlling the forward and reverse rotation of the first motor; thereby achieving the effect that the first motor selectively drives only the cutter head and cutter head spindle corresponding to the small diameter alloy bar or the large diameter alloy bar to rotate, avoiding the idle rotation of the non-working cutter head and cutter head.

Detailed Implementation

[0042] To make the objectives, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] Example 1

[0045] Please see Figures 1-2 This invention provides a bottom chamfering device for a silver-copper-zinc brazing alloy rod, comprising:

[0046] Chamfering machine frame 1;

[0047] Material support mechanism 4, which includes a large bar support bracket 404 and a small bar support bracket 405. The large bar support bracket 404 is used to stably support the large diameter alloy bar, and the small bar support bracket 405 is used to stably support the small diameter alloy bar.

[0048] The pressing mechanism 3 includes a large bar pressing bracket 303 and a small bar pressing bracket 304. The large bar pressing bracket 303 is used to press the large diameter alloy bar, and the small bar pressing bracket 304 is used to press the small diameter alloy bar.

[0049] Positioning mechanism 5 is used to position the bottom of a large-diameter alloy rod or a small-diameter alloy rod, so that it moves to a preset position.

[0050] Cutting mechanism 2 is used to chamfer the bottom of a large-diameter alloy bar or a small-diameter alloy bar to remove burrs and rough edges.

[0051] A transfer mechanism is used to transfer a large-diameter alloy bar or a small-diameter alloy bar that has completed the positioning operation from the receiving station to the cutting station.

[0052] In this embodiment, the transfer mechanism includes a rodless cylinder 401, which is mounted on the chamfering machine frame 1. The output end of the rodless cylinder 401 is connected to the lower surface of the workpiece reciprocating base plate 402 via a connecting block. The lower surface of the workpiece reciprocating base plate 402 is also slidably engaged with a second guide rail 403 via a slider. The second guide rail 403 is mounted on the chamfering machine frame 1, enabling the rodless cylinder 401 to drive the workpiece reciprocating base plate 402 to reciprocate between the receiving station and the cutting station.

[0053] In this embodiment, the large bar support bracket 404 and the small bar support bracket 405 are installed on the upper surface of the workpiece reciprocating base plate 402. The large bar support bracket 404 and the small bar support bracket 405 are arranged in pairs to support the two ends of the large-diameter alloy bar and the small-diameter alloy bar, respectively. The large bar support bracket 404 and the small bar support bracket 405 are spaced apart along the transfer direction corresponding to the transfer from the receiving station to the cutting station. The upper surface of the large bar support bracket 404 is configured in a V-shape to match the outer surface of the large-diameter alloy bar, while the upper surface of the small bar support bracket 405 is configured in a V-shape to match the outer surface of the small-diameter alloy bar, thereby facilitating stable support of the large-diameter alloy bar and the small-diameter alloy bar.

[0054] It should be noted that the large-diameter alloy rod is 130mm in diameter, while the small-diameter alloy rod is 90mm in diameter. Both the large-diameter and small-diameter alloy rods are manufactured using a casting process. The cast alloy rods are then transferred by a robot to either the large rod support bracket 404 or the small rod support bracket 405. Of course, the dimensions of the large-diameter and small-diameter alloy rods mentioned here are merely examples; the specific dimensions of the alloy rods can be customized to meet specific requirements. Cast alloy rods often have burrs or flash at the bottom; therefore, this application utilizes a chamfering operation on the bottom of the alloy rod to remove these burrs and ensure the quality of the product's forming.

[0055] The positioning mechanism 5 includes a top rod 502 and a limiting rod 505 respectively disposed on both sides of the large rod support bracket 404 and the small rod support bracket 405. The top rod 502 is connected to the output end of the third electric telescopic rod 501, which is mounted on the chamfering machine frame 1. The limiting rod 505 is mounted on a limiting plate 504, which is connected to the output end of a fourth electric telescopic rod 503, which is also mounted on the chamfering machine frame 1. After the robot transfers the large-diameter or small-diameter alloy rod, the fourth electric telescopic rod 503 actuates, causing the limiting rod 505 to move to the preset position. Then, the third electric telescopic rod 501 actuates, pushing the large-diameter or small-diameter alloy rod towards the limiting rod 505 via the push rod 502 until it abuts against the limiting rod 505. This ensures that the bottom of the large-diameter or small-diameter alloy rod moves to the preset position, guaranteeing that the subsequent cutting mechanism 2 can chamfer at the same position each time.

[0056] It should be noted that, since the large bar support bracket 404 and the small bar support bracket 405 are spaced apart along the transfer direction corresponding to the transfer from the receiving station to the cutting station, in this embodiment, the number of limiting rods 505 and push rods 502 are both provided in two, corresponding to the large bar support bracket 404 and the small bar support bracket 405 respectively.

[0057] The pressing mechanism 3 includes a second electric telescopic rod 301, which is mounted on the chamfering machine frame 1. The output end of the second electric telescopic rod 301 is fixedly connected to a pressing base plate 302. The large bar pressing bracket 303 and the small bar pressing bracket 304 are mounted on the pressing base plate 302, and are spaced apart along the transfer direction corresponding to the transfer from the receiving station to the cutting station. The lower surface of the large bar pressing bracket 303 is configured in a V-shape to fit the outer surface of the large-diameter alloy bar, while the lower surface of the small bar pressing bracket 304 is configured in a V-shape to fit the outer surface of the small-diameter alloy bar. Therefore, when the second electric telescopic rod 301 drives the large rod pressing bracket 303 or the small rod pressing bracket 304 to move down, the large rod pressing bracket 303, together with the large rod support bracket 404, can stably clamp the large diameter alloy rod, and the small rod pressing bracket 304, together with the small rod support bracket 405, can stably clamp the small diameter alloy rod, thereby facilitating the cutting mechanism 2 to perform chamfering operation on the alloy rod.

[0058] The cutting mechanism 2 includes a cutter head 204, on which cutter heads 205 are provided for cutting large-diameter or small-diameter alloy bars. The large bar support bracket 404 and the small bar support bracket 405 are spaced apart along the transfer direction corresponding to the transfer from the receiving station to the cutting station; correspondingly, two cutter heads 204 are provided, and the two cutter heads 204 are also spaced apart along the transfer direction corresponding to the transfer from the receiving station to the cutting station.

[0059] In order to achieve the chamfering operation on large-diameter alloy bars and small-diameter alloy bars, the cutting heads 205 on the two cutting head 204 are installed in different positions. The cutting head 205 corresponding to the small-diameter alloy bar is closer to the center of the cutting head 204, while the cutting head 205 corresponding to the large-diameter alloy bar is farther from the center of the cutting head 204.

[0060] In some preferred embodiments, the cutter head 204 is mounted on the cutter head spindle 206, and the outer surface of the middle part of the cutter head spindle 206 is rotatably connected to the first bearing seat 203, which is mounted on the cutter head moving base plate 202. The cutter head moving base plate 202 is slidably engaged with the first guide rail 208 via a slider. The first guide rail 208 is mounted on the chamfering machine frame 1, and the cutter head moving base plate 202 is connected to the telescopic end of the first electric telescopic rod 201, which is also mounted on the chamfering machine frame 1. When the first electric telescopic rod 201 extends or retracts, it can drive the cutter head moving base plate 202 to move back and forth along the first guide rail 208, thereby realizing the feeding of the cutter head 204 and the cutter head 205. The cutter head spindle 206 is driven to rotate by a first motor 207. Specifically, the first motor 207 drives the cutter head spindle 206 to rotate through a transmission mechanism. The transmission mechanism can be a driving wheel, a belt, and a driven wheel; it can also be a gear transmission mechanism, which can be determined by those skilled in the art according to the actual situation, and this application does not make specific limitations. It should be noted that the number of first motors 207 can be two or one; those skilled in the art can choose flexibly. When the number of first motors 207 is two, the two first motors 207 correspond one-to-one with the cutter head spindles 206 corresponding to the two cutter heads 204; when the number of first motors 207 is one, the first motor 207 drives the cutter head spindles 206 corresponding to the two cutter heads 204 to rotate simultaneously through the transmission mechanism.

[0061] Preferably, the chamfering machine frame 1 is provided with a receiving chute 6. After the large bar support bracket 404 and the small bar support bracket 405 are transferred to the cutting station, the receiving chute 6 is located directly below the bottom of the large-diameter alloy bar and the small-diameter alloy bar; therefore, the metal shavings cut off can be collected by the receiving chute 6.

[0062] The specific working process of this invention is as follows: A robot grips a large-diameter alloy rod or a small-diameter alloy rod produced by the casting process; it is placed on the large rod support bracket 404 or the small rod support bracket 405; then the third electric telescopic rod 501 is activated, pushing the large-diameter alloy rod or the small-diameter alloy rod towards the limiting rod 505 through the push rod 502 until it abuts against the limiting rod 505; thereby ensuring that the bottom of the large-diameter alloy rod or the small-diameter alloy rod moves to the preset position, ensuring that the subsequent cutting mechanism 2 can chamfer at the same position each time; then it is transferred to the cutting station by the transfer mechanism, at which time the second electric telescopic rod 3 corresponding to the pressing mechanism 3 is activated. 01 drives the large bar pressing bracket 303 or the small bar pressing bracket 304 to move down, and works with the large bar support bracket 404 or the small bar support bracket 405 to stably clamp the alloy bar and fix it. Then, the first electric telescopic rod 201 corresponding to the cutting mechanism 2 pushes the cutter head 204 to move towards the alloy bar. At the same time, the first motor 207 drives the cutter head 204 to rotate at high speed, so that the burrs on the bottom of the alloy bar can be cut off. The cut metal residue is collected by the receiving chute 6. After the cutting is completed, the cutter head 204 and the pressing mechanism 3 are removed. Finally, the material is transferred back to the receiving station by the transfer mechanism, waiting for the robot to pick it up and enter the next post-processing process.

[0063] Example 2

[0064] Please see Figures 3-7Each of the two cutter heads 204 has a fixed plate 225 fixedly connected to the end of the cutter head spindle 206 away from the cutter head 204. A transmission plate 224 is slidably fitted onto the side of the fixed plate 225 away from the cutter head spindle 206 via a second limiting groove 226, and the bottom wall of the second limiting groove 226 is connected to the transmission plate 224 via a second spring 227. The transmission plate 224 is disc-shaped, and its outer surface has a plurality of protrusions 2241 arranged in a ring array. Correspondingly, the second limiting groove 226 is cylindrical, and its outer surface has a plurality of protruding grooves that match the protrusions 2241 arranged in a ring array. A second gear 222 is provided on the side of the transmission plate 224 away from the cutter head spindle 206, and the axle of the second gear 222 is rotatably connected to a second bearing seat 229, which is mounted on a mounting plate 228. Mounting plate 228 can be fixedly connected to cutter head moving base plate 202 by bolts, or mounting plate 228 can be integrally formed with cutter head moving base plate 202. On the side of the second gear 222 near the transmission disk 224, a plurality of wedge-shaped blocks 223 are arranged in a circular array to cooperate with the protrusion 2241. The inclined surfaces of the wedge-shaped blocks 223 on the second gears 222 corresponding to the two cutter heads 204 face opposite directions. That is, when the two second gears 222 rotate in the same direction, the straight surface of the wedge-shaped block 223 on one second gear 222 contacts the protrusion 2241, while the inclined surface of the wedge-shaped block 223 on the other second gear 222 contacts the protrusion 2241. Furthermore, a first gear 221 meshes between the two second gears 222, and the first gear 221 is connected to the output end of the first motor 207. In this embodiment, the first motor 207 has forward and reverse rotation functions and is mounted on mounting plate 228.

[0065] When the first motor 207 rotates in the forward direction, through the meshing connection of the first gear 221 and the second gear 222, the first motor 207 simultaneously drives the two second gears 222 to rotate in the same direction. At this time, the straight surface of the wedge block 223 on one of the second gears 222 engages with the protrusion 2241, thereby driving the corresponding transmission disk 224 and fixed disk 225 to rotate synchronously at high speed, which in turn drives the corresponding cutter head 204 and cutter head 205 to rotate at high speed, facilitating the chamfering operation on small-diameter alloy bars. At the same time, the inclined surface of the wedge block 223 on the other second gear 222 engages with the protrusion 2241, retracting the extrusion transmission disk 224 into the fixed disk 225, thus preventing the corresponding cutter head 204 and cutter head 205 from rotating, avoiding the free rotation of the cutter head 204 and cutter head spindle 206 corresponding to the large-diameter alloy bar when performing the chamfering operation on the small-diameter alloy bar. Similarly, when the first motor 207 rotates in the reverse direction, it will drive the cutter head 204 and cutter head spindle 206 corresponding to the large-diameter alloy bar to rotate at high speed, while the cutter head 204 and cutter head spindle 206 corresponding to the small-diameter alloy bar will not rotate. Therefore, by controlling the forward and reverse rotation of the first motor 207, this application can flexibly select whether to drive the cutter head 204 and cutter head spindle 206 corresponding to the small-diameter alloy bar or the cutter head 204 and cutter head spindle 206 corresponding to the large-diameter alloy bar to rotate at high speed. This achieves the selective rotation of the cutter head 204 and cutter head spindle 206 corresponding to either the small-diameter alloy bar or the large-diameter alloy bar by the same first motor 207.

[0066] It should be noted that the rest of this embodiment is the same as that in Embodiment 1 above.

[0067] Example 3

[0068] Please see Figure 8 , Figure 12 and Figure 13 In this embodiment, a second cylinder 406 is also installed on the workpiece reciprocating base plate 402. The telescopic end of the second cylinder 406 is connected to the small rod support bracket 405, while the large rod support bracket 404 is directly installed on the workpiece reciprocating base plate 402, and the center planes of the large rod support bracket 404 and the small rod support bracket 405 coincide. Therefore, when the casting process produces a large-diameter alloy rod, the second cylinder 406 drives the small rod support bracket 405 to move downward, and at this time, the small rod support bracket 405 will not obstruct the placement of the large-diameter alloy rod on the large rod support bracket 404; conversely, when the casting process produces a small-diameter alloy rod, the second cylinder 406 drives the small rod support bracket 405 to move upward to the initial position, at which time the small rod support bracket 405 can stably support the small-diameter alloy rod; at the same time, it can ensure that the central axis of the small-diameter alloy rod coincides with that of the previously placed large-diameter alloy rod.

[0069] Since the center planes of the large rod support bracket 404 and the small rod support bracket 405 coincide, the positioning mechanism 5 only needs to be equipped with one top rod 502 and one limiting rod 505. When the top rod 502 is activated, it can push the small diameter alloy rod to its bottom to abut against the limiting rod 505, and it can also push the large diameter alloy rod to its bottom to abut against the limiting rod 505. That is, one top rod 502 and one limiting rod 505 can realize the positioning operation of the small diameter alloy rod and the large diameter alloy rod.

[0070] In this embodiment, the large rod pressing bracket 303 is directly installed on the pressing base plate 302. The pressing base plate 302 is also equipped with a first cylinder 305. The telescopic end of the first cylinder 305 is connected to the small rod pressing bracket 304, and the center planes of the large rod pressing bracket 303 and the small rod pressing bracket 304 coincide. Therefore, when the material support mechanism 4 is transferred to the cutting station, if a large-diameter alloy bar is placed on the material support mechanism 4, the pressing mechanism 3 first moves the small bar pressing bracket 304 upward, and then the second electric telescopic rod 301 moves the pressing base plate 302 downward. The small bar pressing bracket 304 will not obstruct the large bar pressing bracket 303 from fixing the large-diameter alloy bar. If a small-diameter alloy bar is placed on the material support mechanism 4, the pressing mechanism 3 moves the small bar pressing bracket 304 downward to the initial position, and then the second electric telescopic rod 301 moves the pressing base plate 302 downward. The small bar pressing bracket 304 will stably fix the small-diameter alloy bar.

[0071] Please see Figures 9-11 The cutter head 205 is mounted on the fixed base 209, and a lead screw 211 is rotatably connected to the cutter disc 204. An adjustment knob 212 is fixedly connected to the end of the lead screw 211. The lead screw 211 extends along the diameter or radius of the cutter disc 204. When the adjustment knob 212 is rotated, the lead screw 211 can drive the fixed base 209 to move along its axial direction, thereby changing the distance between the cutter head 205 on the fixed base 209 and the center of the cutter disc 204, and thus adjusting the position of the cutter head 205 to correspond to the size of the alloy rod.

[0072] Preferably, the cutter head 204 has a groove 213 inside, and the lead screw 211 is disposed in the groove 213. The end of the lead screw 211 extends to the outside of the cutter head 204 and is connected to the adjusting knob 212. The top wall of the groove 213 is connected to the external environment through a through groove 215. The middle part of the lead screw 211 passes through the sliding seat 210 and is threadedly connected to it. The sliding seat 210 is connected to the fixed seat 209 through a connecting block. A first limiting groove 216 is also provided on the top wall of the groove 213. The width of the first limiting groove 216 is greater than the width of the through groove 215. The first limiting grooves 216 located on both sides of the connecting block are slidably fitted with partitions 214. The end of the partition 214 away from the connecting block is connected to the inner wall of the first limiting groove 216 through a first spring 217. Therefore, the partition 214 does not obstruct the movement of the sliding seat 210 along the axis of the lead screw 211, and thus does not affect the position of the adjusting cutter head 205 to correspond to the size of the alloy rod; while the sliding seat 210 moves, the partition 214 always remains in close contact with the connecting block; when the sliding seat 210 moves into place, the metal chips generated during the cutting process will not fall onto the lead screw 211 through the through groove 215, thus not affecting the transmission cooperation between the lead screw 211 and the sliding seat 210.

[0073] Optionally, a receiving chute 6 and an inclined guide plate 220 are provided directly below the cutting mechanism 2; the first motor 207 is mounted on the lower surface of the cutter head moving base plate 202 via a connecting plate 218, and the guide plate 220 has a strip groove 219 corresponding to the connecting plate 218, so that when the cutter head moving base plate 202 moves along the first guide rail 208, the guide plate 220 will not interfere with the connecting plate 218; moreover, the guide plate 220 is conducive to guiding metal scraps into the receiving chute 6, which facilitates the collection of metal scraps.

[0074] Optionally, a safety cover 7 is fixedly connected to the cutter head moving base plate 202 by screws, and the safety cover 7 can play a protective role.
