Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a material bar shearing hydraulic press for metal processing and a working method. Background Art

[0002] In the field of metal processing, electron beam melting is a common method of melting metals. It requires feeding metal rods into a melting furnace and converting the kinetic energy of a high-speed electron beam into heat energy under high vacuum, which is used as a heat source for metal melting. However, in the actual production process, the length of the raw material rods purchased from the factory is often too long, and the rods need to be cut to a length suitable for feeding into the melting furnace. As for the shearing equipment for metal rods, a hydraulically driven shearing machine is generally used.

[0003] In order to improve the shearing efficiency, the prior art Chinese patent CN201910930994.X discloses a bidirectional round steel shearing machine with a hydraulic cylinder driving a connecting rod mechanism, wherein the shearing device includes two fixed knife tables, a double-cutting movable knife table, and two round steel shearing arc-shaped shearing blades fixed on the knife table. This invention scheme can shear in both directions, and shears are sheared by the shearing blades respectively during the reciprocating drive of the hydraulic cylinder. Compared with most unidirectional shearing machines, the operating efficiency is significantly improved, but it also brings new technical problems and difficulties in use:

[0004] This scheme performs shearing operations at two locations with different heights, which makes feeding before shearing and loading after shearing inconvenient. In particular, this scheme requires shearing multiple groups of material bars at the same time, and the shear blade position is relatively fixed, while the length of the raw material material bars is limited, so it is necessary to frequently feed multiple groups of material bars to the shear blade position in a timely and accurate manner, which is difficult to operate, and when the feeding and calibration time exceeds the return time of the hydraulic cylinder, the operating efficiency will be reduced. In addition, the length of the material bars that may be required in actual production varies, and the above-mentioned and existing shearing machines are not convenient for quickly adjusting the shearing length of the material bars during processing. Summary of the invention

[0005] Some simplifications or omissions may be made in this section and the abstract and title of the present application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions shall not be used to limit the scope of the present invention.

DETAILED DESCRIPTION

[0061] In order to make the objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0063] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0064] Example 1

[0065] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides a hydraulic press for shearing material bars for metal processing, which can feed multiple groups of material bars at upper and lower shearing positions to designated shearing positions quickly and timely, and realize classified loading, and comprises: a shearing assembly 100, a feeding assembly 200 and a loading assembly 300. The shearing assembly 100 adopts bidirectional shearing, and realizes two shearings in the round trip process by hydraulically driving in upper and lower directions respectively. By setting the feeding assembly 200, multiple groups of material bars at upper and lower shearing positions can be fed to designated shearing positions quickly and timely. By setting the loading assembly 300, the material bars sheared at the upper and lower shearing positions and the excess residues can be stored separately.

[0066] Specifically, the base assembly 100 and the shearing assembly 100 include a frame 101 and a lower fixed portion 104, a shearing portion 103, and an upper fixed portion 102 which are sequentially arranged on one side of the frame 101 along the Z axis. The upper fixed portion 102 and the lower fixed portion 104 are both fixedly arranged relative to the frame 101. The shearing portion 103 and the frame 101 are slidably connected along the Z axis. A hydraulic cylinder 105 for driving the shearing portion 103 to slide along the Z axis toward the upper fixed portion 102 and the lower fixed portion 104 is provided on one side of the frame 101. In this embodiment, the hydraulic cylinders 105 are symmetrically arranged in groups of two on one side of the upper fixed portion 102 and the lower fixed portion 104. When the two groups of hydraulic cylinders 105 of the upper fixed portion 102 push the shearing portion 103 downward, the two groups of hydraulic cylinders 105 of the lower fixed portion 104 pull the shearing portion 103 downward synchronously, and the reverse process is exactly the opposite, so as to apply a stable driving force to the shearing portion 103.

[0067] Among them, upper shear blades 102a that match each other are respectively arranged on the lower side of the upper fixing part 102 and the upper side of the shearing part 103, and lower shear blades 104a that match each other are respectively arranged on the upper side of the lower fixing part 104 and the lower side of the shearing part 103. The upper shear blades 102a and the lower shear blades 104a are arranged in no less than two groups at equal intervals along the X-axis, and the material rod to be sheared passes through the upper shear blade 102a or the lower shear blade 104a along the Y-axis and then is sheared.

[0068] Furthermore, a feeding assembly 200 is arranged on one side of the frame 101, including a transport platform 201 for conveying material bars and a storage box 202 arranged on one side of the transport platform 201 and used to store material bars to be sheared. The raw materials of the material bars to be sheared are stored in the storage box 202. Intermittent unloading of material bars has been achieved in the prior art, and its internal structure is not repeated here. An upper discharge rail 202a and a lower discharge rail 202b are correspondingly arranged on one side of the storage box 202 near the upper fixing portion 102 and the lower fixing portion 104. The upper discharge rail 202a and the lower discharge rail 202b are A slope is provided, and after the material rods are discharged from the storage box 202, they roll along the slopes of the upper discharge rail 202a and the lower discharge rail 202b toward the transportation platform 201. An upper feeding portion 203 is provided on the side of the transportation platform 201 close to the upper fixed portion 102, and the material rods to be sheared moved out from the upper discharge rail 202a are transported through the upper feeding portion 203 to be aligned with each group of upper shear blades 102a. A lower feeding portion 204 is provided on the side of the transportation platform 201 close to the lower fixed portion 104, and the material rods to be sheared moved out from the lower discharge rail 202b are transported through the lower feeding portion 204 to be aligned with each group of lower shear blades 104a.

[0069] Among them, the loading assembly 300 is arranged on both sides of the frame 101, which includes a collection box 1 301 arranged on one side of the frame 101 close to the feeding assembly 200, and a collection box 2 302 arranged on the other side of the frame 101. The collection box 1 301 is used to store the residual material bars after shearing. The collection box 1 301 has two groups and is respectively connected to the conveying ends of the upper feeding part 203 and the lower feeding part 204. The conveying end refers to the end of the material bar relative to the X-axis transportation direction. The collection box 2 302 includes a box body 302a and two groups of inclined guide rails 302b respectively arranged on one side of the shearing part 103 and the lower fixing part 104. In this way, the height of the material bars at the two shearing positions after shearing is within the set value to prevent excessive damage and the generation of large noise due to the falling height. The sheared material bars roll down from the inclined guide rails 302b to the box body 302a for storage. In a preferred embodiment, the width of the inclined guide rail 302b can be adjusted to accommodate material rods of different shearing lengths.

[0070] Furthermore, the upper feeding part 203 and the lower feeding part 204 both include a support block 203a fixedly disposed in the transport platform 201 and a support block 203b slidably disposed in the transport platform 201 along the Z-axis. A groove 203c is provided on one side of the support block 203a and the support block 203b close to the collection box 1 301. There are no less than two groups of support blocks 1 203a and support blocks 2 203b equally spaced along the X-axis.

[0071] Among them, in the X-axis direction, a support groove 203a-1 adapted to the outer diameter of the material rod is formed between the groove 203c of the first group of support blocks 203a and the second group of support blocks 203a, and a support groove 203b-1 adapted to the outer diameter of the material rod is formed between the groove 203c of the first group of support blocks 203b and the second group of support blocks 203b; when each group of support blocks 203b moves up synchronously along the Z-axis, the support groove 203a-1 adapted to the outer diameter of the material rod is formed. 3b-1 drives the material rod upward after passing through the previous group of support grooves 1 203a-1, and the material rod slides down along the groove 203c of the current support groove 2 203b-1 after passing through the next group of support grooves 1 203a-1 in the support groove 2 203b-1; when each group of support blocks 2 203b moves down synchronously along the Z axis, the material rod in the support groove 2 203b-1 falls into the next group of support grooves 1 203a-1 after passing through the support groove 1 203a-1. It is worth noting that the above-mentioned "previous group" and "next group" are relative to the pointing direction of the X-axis, that is, the starting direction of the X-axis in the reference figure is the location of the "previous group", and the next adjacent group along the direction indicated by the X-axis is the location of the "next group". In this embodiment, the span of the groove 203c of the corresponding support block 203b in the X-axis direction can be sufficient to drive the material rod located at the lowest point of the previous group of support grooves 203a-1 to move upward when moving upward, and the span of the latter group of support blocks 203a in the X-axis direction can be sufficient to stop the material rod from moving downward along the support groove 203b-1 by the groove 203c of the latter group of support grooves 203a-1, so as to drive the material rod to move along the X-axis direction for feeding.

[0072] Preferably, the cutting edges of the upper shear blade 102a and the lower shear blade 104a are composed of three arcs, of which the two sides are symmetrical convex arcs and the middle is a concave arc, and the material rod moves along the symmetry axis of the convex arcs on both sides toward the concave arcs for shearing; the projections of each group of supporting grooves 2 203b-1 located in the upper feeding part 203 along the Y-axis direction are respectively aligned and adapted with the cutting edges of a group of upper shear blades 102a on the upper side of the shearing part 103, and the projections of each group of supporting grooves 1 203a-1 located in the lower feeding part 204 along the Y-axis direction are respectively aligned and adapted with the cutting edges of each group of lower shear blades 104a. Then, when the material rod falls into each group of supporting grooves 2 203b-1 of the upper feeding part 203, it will be adapted with the cutting edge of the upper shear blade 102a, and when the material rod falls into each group of supporting grooves 1 203a-1 of the lower feeding part 204, it will be aligned with the cutting edge of the lower shear blade 104a, ensuring that the shearing position is accurately reached.

[0073] Preferably, each group of support blocks 203b located at the upper feeding part 203 and the lower feeding part 204 are fixedly connected with a connecting plate 1 203d through a connecting rod, and a synchronous driving member driving the connecting plate 1 203d and the shearing part 103 to move synchronously is provided in the transport platform 201. The synchronous driving member can be a connecting frame that directly connects the connecting plate 1 203d and the shearing part 103 to move as a whole, and then the shearing part 103 drives the connecting plate 1 203d to move synchronously through the connecting frame. In addition, the synchronous driving member can also be driven by a motor and a screw rod of the prior art, and the connecting plate 1 203d is threadedly connected to the screw rod, and the connecting plate 1 203d is moved up or down after the motor drives the screw rod to rotate, and the connecting plate 1 203d can be controlled to move synchronously with the shearing part 103 driven by the hydraulic cylinder 105 on a computer program through the motor drive.

[0075] Material rod replenishment process: when the hydraulic cylinder 105 is driven to move the shearing part 103 downward and the material rod is sheared by the lower shear blade 104a, the material rod is discharged from the material storage box 202 and rolls toward the transport platform 201 along the slopes of the upper discharge rail 202a and the lower discharge rail 202b, and then falls into the support groove 203a-1 on the side closest to the material storage box 202, completing a material rod replenishment.

[0076] The process of the material bar reaching each shearing position:

[0077] Aligned with the cutting edge of the upper shear blade 102a: After the shearing portion 103 moves down to the lowest position and completes the first shearing of the material rod by the lower shear blade 104a, the hydraulic cylinder 105 drives in the reverse direction to move the shearing portion 103 upward. The upward movement of the shearing portion 103 will drive the connecting plate 1 203d to move upward synchronously through the synchronous driving member, thereby causing each group of support blocks 2 203b to move upward. When each group of support blocks 2 203b moves upward synchronously, the support groove 2 203b-1 drives the material rod of the support groove 1 203a-1 to move upward after passing through the previous group of support grooves 1 203a-1, so that the material rod moves upward. After the material rod moves out of the current support groove 1 203a-1 and passes through the next group of support grooves 1 203a-1 in the support groove 203b-1, the material rod slides down along the groove 203c of the current support groove 203b-1 under the action of gravity until it moves to the lowest point of the support groove 203b-1 and is supported. At this time, the material rod has moved a certain distance in the X-axis direction, so that the projections of the material rods of each group of support grooves 2 203b-1 located in the upper feeding part 203 in the Y-axis direction are respectively aligned and adapted with the edges of the upper shear blades 102a on the upper side of a group of shearing parts 103.

[0078] Aligned with the cutting edge of the lower cutting blade 102a: As the cutting portion 103 moves up to the highest point, the upper side of the cutting portion 103 and the upper cutting blade 102a of the lower side of the upper fixing portion 102 alternately complete the cutting action, and the hydraulic cylinder 105 changes direction again to drive the cutting portion 103 to move down. The downward movement of the cutting portion 103 will drive the connecting plate 1 203d to move down synchronously through the synchronous driving member, thereby causing each group of supporting blocks 2 203b to move down. When each group of supporting blocks 2 203b moves down synchronously, the supporting groove 203d is After the material rod in 3b-1 passes through the aforementioned second group of support grooves 203a-1 under the action of gravity, it is intercepted by the groove 203c of the support groove 203a-1, and then slides down the groove 203c and falls into the bottom of the support groove 203a-1. At this time, the material rod moves a certain distance in the X-axis direction, so that the projections of the material rods of each group of support grooves 203a-1 located in the lower feeding part 204 in the Y-axis direction are respectively aligned and adapted with the cutting edges of each group of lower shear blades 104a.

[0079] As the shearing part 103 moves down to the lowest point, the lower shearing blades 104a on the lower side of the shearing part 103 and the upper side of the lower fixing part 104 interlace to complete the shearing action. After the material rods are first dropped from the material storage box 202 onto the transport platform 201, the hydraulic cylinder 105 can be driven to push the shearing part 103 back and forth a limited number of times, and then the support grooves 1 203a-1 or the support grooves 2 203b-1 along the X-axis of the transport platform 201 are respectively filled with material rods, so that multiple groups can be sheared at the same time, and then the material rods are continuously added during the subsequent shearing process, the shearing process is not interrupted, and the shearing efficiency is high.

[0080] Classification and loading process: the material rods move forward in the support groove 1 203a-1 and the support groove 2 203b-1 in the X-axis direction in sequence, and are pushed a certain distance in the Y-axis direction for shearing each time they move forward, until the remaining length of the material rod is less than the required shearing length, and the remaining residual material rods are pushed to the support groove 1 203a-1 or the support groove 203b-1 close to the collection box 1 301, and then the residual material rods continue to move in the X-axis direction and slide along the groove 203c into the collection box 1 301 for storage; and the upper side of the shearing portion 103 and the upper solid After the upper shearing blade 102a on the lower side of the fixed part 102 completes the shearing action by staggering, the sheared material rod falls to the inclined guide rail 302b on one side of the shearing part 103 under the action of gravity, and then rolls along the inclined guide rail 302b to the box body 302a for storage; and after the lower shearing blade 104a on the lower side of the shearing part 103 and the upper side of the lower fixed part 104 completes the shearing action by staggering, the sheared material rod falls to the inclined guide rail 302b on one side of the lower fixed part 104 under the action of gravity, and then rolls along the inclined guide rail 302b to the box body 302a for storage.

[0081] Example 2

[0082] Reference Figure 3 , Figure 4-Figure 10 , Fig.12 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an intermittent discharge part 206 and a pushing part 205, and optimizes the timing process of adding the material rod to be sheared and the timing process of pushing the material rod through the cutting edge to ensure stable operation of the device.

[0083] Specifically, the support block 1 203a and the support block 2 203b are staggered and arranged at equal intervals along the Y axis in at least two groups. The support blocks 1 203a and the support blocks 2 203b arranged at intervals can provide stable support for the material bars of different lengths in the Y axis direction, and the staggered distribution refers to the arrangement in the order of "support block 1 203a, support block 2 203b, support block 1 203a..." in the Y axis direction. Generally, the width of the support block 1 203a and the support block 2 203b in the Y axis direction is smaller than the shear length of the material bar, and it is best to be smaller than half of the shear length of the material bar, so that at least one group of support blocks 1 203a or support blocks 2 203b can support the material bar individually. A pushing part 205 is provided in the transport platform 201 to push the material bar on the support slot 1 203a-1 or the support slot 2 203b-1 through the cutting edge along the Y axis.

[0084] Furthermore, the pushing part 205 is a reciprocating mechanism, and the distance that the pushing part 205 pushes the material rod to move each time is equal to the shearing length of the material rod. The reciprocating mechanism is a prior art, which can push the material rod to move at a specified time, and then move back to prevent interference. It is worth noting that the shearing length of the material rod refers to the length of the material rod that is subsequently added to the electron beam melting furnace, that is, the length of the material rod that falls into the collection box 2 302 after passing through the cutting edge along the Y axis and being sheared by the shearing part 103.

[0085] Among them, an intermittent discharge part 206 is provided on one side of the upper discharge rail 202a and the lower discharge rail 202b, and the intermittent discharge part 206 discharges a group of material rods into the transport platform 201 after the shearing part 103 completes a shearing action. The intermittent discharge part 206 includes a rotating shaft 206a provided at the bottom of the upper discharge rail 202a and the lower discharge rail 202b, an adjusting rod 206b rotatably connected to one side of the rotating shaft 206a, and a guide groove 206c provided on both sides of the adjusting rod 206b. Two groups of limit plates 206d are slidably connected to the bottom of the upper discharge rail 202a and the lower discharge rail 202b. One side of the two groups of limit plates 206d is provided with a guide column 206e respectively adapted to the guide grooves 206c on both sides of the adjusting rod 206b. The spacing between the two groups of limit plates 206d is not less than the diameter of the material rod and not more than twice the diameter of the material rod.

[0086] When one set of limiting plates 206d close to the transport platform 201 side moves down, the other set of limiting plates 206d moves up to block the subsequent material rods from sliding into the transport platform 201, and the material rods between the two sets of limiting plates 206d lose their limiting position and slide into the transport platform 201. When one set of limiting plates 206d close to the transport platform 201 side moves up, the other set of limiting plates 206d moves down to allow the subsequent set of material rods to slide between the two sets of limiting plates 206d.

[0087] Preferably, the bottom of the upper discharge rail 202a and the lower discharge rail 202b are provided with a set of limit plates 206d on one side, and a trigger plate 206f is provided on one side to be slidably connected to the transport platform 201. The trigger plate 206f is adapted to the moving direction of the connecting plate 1 203d, and a reset spring 206g adapted to the trigger plate 206f and a slide groove adapted to the trigger plate 206f are provided on one side of the transport platform 201. After the connecting plate 1 203d moves up, the trigger plate 206f is reset and moved up a distance in time under the action of the reset spring 206g, thereby driving the limit plates 206d near the transport platform 201 side to move up. When the set of limit plates 206d near the transport platform 201 side moves up, the other set of limit plates 206d moves down, so that the subsequent set of material rods slides to between the two sets of limit plates 206d to be supplemented and wait for the next unloading.

[0088] The rest of the structure is the same as that of Example 1.

[0089] The process of adding the material rod to be sheared: when the connecting plate 1 203d drives the supporting block 203b to move downward to the corresponding supporting block 1 203a, the connecting plate 1 203d will press down the trigger plate 206f in its moving direction and compress the reset spring 206g. The downward movement of the trigger plate 206f drives the limit plate 206d close to the side of the transport platform 201 to move downward. The downward movement of this group of limit plates 206d will cooperate with the guide groove 206c of the adjusting rod 206b through the guide column 206e, thereby driving the adjusting rod 206b to rotate relative to the rotating shaft 206a, and the other group of limit plates 206d will also move in the opposite direction under the cooperation of the guide column 206e and the guide groove 206c of the adjusting rod 206b. The material rods between the two sets of limit plates 206d lose their limit and slide into the transport platform 201. After the connecting plate 203d moves up, the trigger plate 206f is reset and moves up a distance in time under the action of the reset spring 206g, thereby driving the limit plates 206d near the transport platform 201 side to move up. After the one set of limit plates 206d near the transport platform 201 side moves up, the other set of limit plates 206d moves down, allowing the subsequent set of material rods to slide between the two sets of limit plates 206d for replenishment and waiting for the next unloading.

[0090] The process of pushing the material bar through the cutting edge: the pushing part 205 located at the lower feeding part 204 starts after the material bar moves to the highest position along the Z-axis direction with the support groove 203b-1, and the pushing part 205 located at the upper feeding part 203 starts after the material bar moves to the lowest position along the Z-axis direction with the support groove 203b-1. Both positions are at the maximum opening position of the cutting edge, which facilitates the sliding of the material bar in the Y-axis direction. After the material bar reaches the specified position, the pushing part 205 pushes the material bar to move through the reciprocating motion mechanism. After the material bar moves to a sufficient distance, the pushing part 205 moves back through the reciprocating motion mechanism to prevent interference with the subsequent process and facilitate the next material pushing.

[0091] Example 3

[0092] Reference Figure 9-13 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an adjustment portion 207, which can quickly adjust the shearing length of the material rod.

[0093] Specifically, the pushing part 205 includes a driving motor 205a arranged on one side of the transportation platform 201, a connecting sleeve 205b arranged on the output end of the driving motor 205a, an adjusting screw 205c rotatably connected to the connecting sleeve 205b, a slider 205d slidably connected in the connecting sleeve 205b and threadedly connected to the adjusting screw 205c, and a connecting disk 205e fixedly connected to one side of the slider 205d; an annular groove 205f is provided on one side of the connecting disk 205e, a pushing block 205g sliding along the Y-axis direction is provided in the transportation platform 201, and a limiting column 205h adapted to the annular groove 205f is provided on one side of the pushing block 205g. After the pushing block 205g slides along the Y-axis direction, it pushes the material rod from the end of the material rod to pass through the cutting edge. Rotate the adjusting screw 205c to make the slider 205d slide in the connecting sleeve 205b, thereby driving the connecting disc 205e to move with the slider 205d, so that the distance between the annular groove 205f on one side of the connecting disc 205e and the rotation center of the output end of the driving motor 205a changes, thereby achieving adjustment.

[0094] The interval between adjacent groups of push blocks 205g in the Y-axis direction is equal to the shear length of the material rod, and an adjusting part 207 for adjusting the interval between adjacent groups of push blocks 205g in the Y-axis direction is provided in the transport platform 201. Specifically, the adjusting part 207 includes a push plate 207a slidably connected to the transport platform 201, and a slide groove 207b provided on the surface of the push plate 207a along the Y-axis direction, a limit column 205h is connected to the push plate 207a, and the push block 205g is connected to the push plate 207a through a connecting column 207c. The number of slide grooves 207b provided on the same push plate 207a is the same as the number of push blocks 205g provided. It is worth noting that the number of slide grooves 207b set here is the same as that of the push blocks 205g, but they are not in a one-to-one correspondence. For example, a group of push blocks 205g close to the storage box 202 has no corresponding slide groove 207b in the Z-axis direction, while a group of slide grooves 207b close to the collection box 301 has no corresponding push block 205g in the Z-axis direction, but the two are the same in quantity.

[0095] Furthermore, the connecting column 207c includes a fixed column 207c-1 and a sliding column 207c-2. A group of pushing blocks 205g close to the side of the storage box 202 are fixedly connected to the pushing plate 207a through a fixed column 207c-1, and the remaining group of pushing blocks 205g are slidingly connected to the pushing plate 207a through a sliding column 207c-2 and a slide groove 207b.

[0096] Among them, the surface of the fixed column 207c-1 is rotatably connected with the adjustment plate 207d, and the surface of the adjustment plate 207d is provided with a second slide groove 207e adapted to the sliding column 207c-2, and a positioning member 207f for fixing the position of the adjustment plate 207d is provided in the slide groove 207b near the collection box 301. The positioning member 207f can be fixed by existing bolts, and after the adjustment plate 207d is rotated to the specified position, the bolts are sequentially passed through a group of slide grooves 1 207b and slide grooves 207e near the collection box 301 and tightened and fixed.

[0097] Preferably, the adjustment plate 207d is a telescopic structure, that is, the adjustment plate 207d includes two sections that can slide relative to each other, which is a common structure in the prior art. It can prevent the adjustment plate 207d of the integrated structure from being too long and occupying a large space when the shear length is adjusted to a small size. The use of an adaptive telescopic structure can ensure the occupied space range of the adjustment plate 207d. The positioning member 207f includes a driving motor 207f-1 disposed on one side of the push plate 207a, an adjusting screw 207f-2 disposed at the output end of the driving motor 207f-1 and rotatably connected between the push plate 207a, a slider 207f-3 slidably connected in the slide slot 1 207b and threadedly connected to the adjusting screw 207f-2, and a fixing column 207f-4 disposed on one side of the slider 207f-3 and rotatably connected to the adjustment plate 207d. In this embodiment, the positioning member 207f is controlled by the driving motor 207f-1, and the adjustment speed is faster, and the adjustment accuracy is better controlled by computer program control.

[0098] The rest of the structure is the same as that of Example 2.

[0099] Adjustment of the pushing distance of the pushing part 205: When the driving motor 205a of the pushing part 205 is turned off, rotate the adjusting screw 205c to make the slider 205d slide in the connecting sleeve 205b, thereby driving the connecting disc 205e to move with the slider 205d, so that the distance between the annular groove 205f on one side of the connecting disc 205e and the rotation center of the output end of the driving motor 205a changes, thereby achieving adjustment. After the adjustment is completed, when it is necessary to push the material rod through the pushing part 205, start the driving motor 205a to drive the connecting sleeve 205b to rotate. During the rotation of the connecting sleeve 205b, the connecting disc 205e and the annular groove 205f are driven to rotate eccentrically, and then the annular groove 205f and the limiting column 205h are cooperated to drive the pushing plate 207a to move along the Y-axis toward the cutting edge. The movement of the pushing plate 207a drives each pushing block 205g to push the material rod from the end of the material rod through the upper and lower cutting edges respectively, and then the connecting disc 205e continues to rotate and drives the pushing plate 207a to move back, while the pushed material rod does not follow its reverse movement. After the connecting disc 205e rotates one circle with the connecting sleeve 205b, the driving motor 205a stops rotating until the material rod reaches the reaching position and the driving motor 205a is restarted.

[0100] To adjust the length difference of adjacent material rods in the Y-axis direction: start the driving motor 207f-1, so that the adjusting screw 207f-2 rotates and drives the slider 207f-3 to slide along the slide groove 207b, the movement of the slider 207f-3 drives the fixed column 207f-4 to move, and the movement of the fixed column 207f-4 drives the adjusting plate 207d of the telescopic structure to adaptively extend and retract, thereby driving one end of the adjusting plate 207d to rotate relative to the fixed column 207c-1, and the other end of the adjusting plate 207d to rotate relative to the fixed column 207c-1. f-4 rotates, and as the fixed column 207f-4 moves along the direction of the slide groove 207b, the adjustment plate 207d is adjusted in rotation angle relative to the fixed column 207c-1. During the rotation of the adjustment plate 207d, the slide groove 207e will push each sliding column 207c-2 to slide along the direction of the slide groove 207b. According to the principle of similar triangles, the length difference of adjacent material rods in the Y-axis direction always remains the same, and the size of the length difference can be adjusted by the rotation angle of the adjustment plate 207d relative to the fixed column 207c-1.

[0101] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
