[0033] In the following, the exemplary solutions of the embodiments of the present invention will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present invention. Unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meaning understood by those of ordinary skill in the art.

[0034] As Figure 1 and Figure 2 shown, the step-by-step cutting device for filamentous metal materials in this embodiment includes a feeding component 100, a cutting component 200, a control component 300, and a buffer component 400. The feeding component 100 is fixedly arranged on the processing table and is used to convey the raw material to be processed; the cutting component 200 is fixedly arranged on the processing table through a fixing bracket 500, and the cutting component 200 is used to cut the raw material to be processed conveyed by the feeding component 100 into segmented samples; the control component 300 is connected to the feeding component 100 and the cutting component 200, and the control component 300 is used to control the feeding component 100 and the cutting component 200 to perform step-by-step conveying and cutting on the raw material to be processed; the buffer component 400 is fixedly arranged on the processing table and is oppositely arranged with respect to the cutting end of the cutting component 200, and the buffer component 400 cooperates with the cutting component 200 to cut the raw material to be processed into segmented samples with flat ends.

[0035] It should be understood that the sample to be processed involved in the present invention is in the form of a filament.

[0036] As Figure 1 shown, the feeding component 100 includes a first motor 110 and two sets of feeding wheels 120, upper and lower. The first motor 110 drives the feeding wheels 120 to rotate through a transmission mechanism to convey the raw material to be processed into the cutting component 200.

[0037] Furthermore, the first motor 110 is a 220V right-angle reduction motor with a power of 90W and a reduction ratio of 30.

[0038] As Figure 1As shown, a feeding groove 121 is provided on the feeding wheel 120. Further, a plurality of feeding grooves 121 with different sizes are provided on the feeding wheel 120 to convey filamentous samples to be processed with different diameters.

[0039] Further, each upper and lower feeding wheel group includes two left and right feeding wheels 120, so the total number of feeding wheels 120 is four. The raw material to be processed passes through the feeding grooves 121 of the upper and lower two feeding wheel groups and is conveyed into the cutting component 200.

[0040] Further, as Figure 1 and Figure 3 shown, the first motor 110 indirectly drives the two lower feeding wheels 120 to rotate through a driving wheel 111 and two driven wheels 112. Specifically, the first motor 110 is directly connected to the driving wheel 111, the driving wheel 111 is connected to the two driven wheels 112 through a belt, and the two driven wheels 112 respectively drive the two lower feeding wheels 120 to rotate. In this embodiment, the cooperation of one driving wheel 111 and two driven wheels 112 is adopted, so that the first motor 110 can drive the left and right lower feeding wheels 120 to rotate synchronously. When there is material, the two upper feeding wheels rotate passively, avoiding the bending of the raw material to be processed between the four feeding wheels 120 and ensuring the smooth conveyance of the raw material to be processed.

[0041] As Figure 1 shown, the fixing frame 500 is L-shaped and includes a vertical part and a horizontal part. A feeding ring 510 is inserted on the vertical part of the fixing frame 500, and the inner diameter of the feeding ring 510 is equal to the diameter of the raw material to be processed. The raw material to be processed conveyed by the feeding component 100 enters the cutting component 200 through the feeding ring 510.

[0042] As Figure 1 shown, the cutting component 200 includes a second motor 210, an eccentric connecting rod 220, and a cutting tool head 230. The second motor 210 is installed on the vertical part of the fixing frame 500 through bolts. A disc is provided at the end of the output shaft 211 of the second motor 210. One end of the eccentric connecting rod 220 is hinged and eccentrically arranged on the disc, and the cutting tool head 230 is hinged to the other end of the eccentric connecting rod 220. The second motor 210 drives the cutting tool head 230 to make a reciprocating motion in the cutting direction through the eccentric connecting rod 220.

[0043] Further, the material of the eccentric connecting rod 220 is selected as 45# steel. The size of the cutting tool head 230 is 40×52mm, and the thickness is 2mm.

[0044] Further, as Figure 2As shown, the second motor 210 is fixed to the left side of the vertical part of the fixing frame 500 by bolts; a linear guide 600 is fixed to the right side of the fixing frame 500 by bolts, and the cutting tool head 230 is slidably arranged in the linear guide 600. The second motor 210 drives the cutting tool head 230 to reciprocate along the cutting direction in the linear guide 600 through an eccentric connecting rod 220.

[0045] As Figure 2 shown, a cutting groove 231 matching the diameter size of the raw material to be processed is formed on the cutting tool head 230, and the cutting groove 231 is semicircular. Specifically, the diameter of the semicircular cutting groove 231 is equal to the diameter of the raw material to be processed in the feeding ring 510.

[0046] As Figure 1 shown, the control component 300 includes a control console 340, a first induction cover 330, and a first proximity switch 320 for sensing the first induction cover 330. The first proximity switch 320 is fixed to the horizontal part of the fixing frame 500 by bolts, and the first induction cover 330 is welded to the output shaft 211 of the second motor 210; the first proximity switch 320 and the first motor 110 are both connected to the control console 340 through a signal line 310.

[0047] Further, the sensing distance of the first proximity switch 320 is 5 mm, and it is a normally open 24V two-wire DC.

[0048] Further, the first induction cover 330 is arc-shaped. Every time the output shaft 211 of the second motor 210 rotates one circle, it will drive the arc-shaped first induction cover 330 to rotate one circle, and the first proximity switch 320 will sense a feeding signal once. This feeding signal is transmitted to the control console 340, and the control console 340 controls the first motor 110 to start. When the first proximity switch 320 cannot sense the first induction cover 330, the control console 340 controls the first motor 110 to stop working, and the feeding wheel 120 can send the raw material to be processed with a set length into the cutting component 200, thereby realizing the stepper control of the first motor 110.

[0049] Further, the second motor 210 is a servo motor with a model of 2.6KW and is matched with a 130 servo three-stage reduction gearbox. The reduction ratio of the reduction gearbox is 48, and the diameter of its output shaft is 22 mm.

[0050] As Figure 1 and Figure 2 shown, the buffer component 400 includes a cylinder 410 and a pushing tool head 420. The cylinder 410 is used to drive the pushing tool head 420 to reciprocate along the cutting direction.

[0051] Further, the cylinder diameter of the cylinder 410 is 32 mm, the stroke is 50 mm, the working pressure is 0.5 Mpa, and the downward thrust is 28 kg. The size of the pushing cutter head 420 is 20×50 mm, the thickness is 2 mm, and the material is No. 13 steel.

[0052] As Figure 2 shown, a pushing groove 421 matching the diameter size of the raw material to be processed is formed on the pushing cutter head 420, and the pushing groove 421 is semicircular. Specifically, the diameter of the semicircular pushing groove 421 is equal to the diameter of the raw material to be processed in the feeding ring 510. When the cutting cutter head 230 performs a cutting action, the pushing groove 421 and the cutting groove 231 cooperate to engage with the outer wall of the raw material to be processed.

[0053] Further, as Figure 2 shown, when the pushing cutter head 420 is in the initial position, the side wall of the pushing groove 421 is attached to the outer wall of the raw material to be processed in the feeding ring 510, that is, when the pushing cutter head 420 makes a reciprocating motion, the pushing groove 421 will not exceed the left side of the raw material to be processed, avoiding blocking the feeding ring 510 by the pushing cutter head 420 and ensuring that the pushing groove 421 is closely attached to the raw material to be processed sent out from the feeding ring 510.

[0054] Further, the feeding ring 510, the cutting cutter head 230 and the pushing cutter head 420 are all replaceable parts. In actual production, the corresponding feeding ring 510, cutting cutter head 230 and pushing cutter head 420 need to be used according to the diameter size of the raw material to be processed.

[0055] As Figure 2 shown, the control component 300 further includes a second induction cover 440 and a second proximity switch 530 for sensing the second induction cover 440. The second induction cover 440 is welded to one end of the eccentric connecting rod 220 close to the cylinder 410, and the second proximity switch 430 is fixed to one end of the cylinder 410 close to the eccentric connecting rod 220 by bolts. In addition, both the second proximity switch 430 and the cylinder 410 are electrically connected to the console 340.

[0056] Further, the sensing distance of the second proximity switch 530 is 3 mm, and it is a normally closed 24V two-wire DC.

[0057] Further, the second induction cover 440 is arc-shaped. When the second motor 210 drives the eccentric connecting rod 220 to make a reciprocating motion, the second proximity switch 430 on the extended cylinder 410 will sense the second induction cover 440 once. The second proximity switch 430 transmits this signal to the console 340, and the console 340 controls the cylinder 410 to stop moving forward and then controls the cylinder 410 to retract.

[0058] The working principle of this application is:

[0059] (1) Turn on the main power supply of this cutting device. After that, the second motor 210 and the cylinder 410 are in the working state.

[0060] (2) The output shaft 211 of the second motor 210 rotates continuously, and at the same time, the first induction cover 330 also rotates together with the output shaft 211. When the first induction cover 330 approaches the first proximity switch 320, the first proximity switch 320 generates a feeding signal and transmits it to the control console 340. The control console 340 controls the first motor 110 to start, drives the feeding wheel 100 to rotate through belt transmission, and feeds the raw material to be processed through the feeding ring 510 to the cutting assembly 200 (at this time, the raw material to be processed contacts the pushing cutter head 420); when the first induction cover 330 moves away from the first proximity switch 320, the first proximity switch 320 cannot sense the feeding signal, and the control console 340 controls the first motor 110 to shut down and stop feeding the cutting assembly 200.

[0061] In this way, the step-by-step feeding of the raw material to be processed by this cutting device is realized.

[0062] (3) The second motor 210 drives the cutting cutter head 230 to reciprocate through the eccentric connecting rod 220 to cut the raw material to be processed sent out by the feeding ring 510 into segments.

[0063] In this way, the cutting of the raw material to be processed by this cutting device is realized.

[0064] (4) When the cutting cutter head 230 contacts the raw material to be processed, the raw material to be processed is completely surrounded in the circular space composed of the cutting groove 231 and the pushing groove 421.

[0065] At this time, the second proximity switch 430 senses the second induction cover 440 and transmits this signal to the control console 340. The control console 340 controls the cylinder 410 to make the pushing cutter head 420 move synchronously (contract inward) with the cutting cutter head 230, ensuring that when the cutting cutter head 230 cuts the raw material to be processed, the pushing cutter head 420 and the cutting cutter head 230 are in continuous contact.

[0066] When the second induction cover 440 moves away from the second proximity switch 430, the second proximity switch 430 cannot sense the second induction cover 440, and the control console 340 controls the cylinder 410 to make the pushing cutter head 420 extend outward until the pushing groove 421 returns to the initial position.

[0067] During the process of the raw material sample to be processed being cut by the cutting cutter head 230, due to the continuous contact between the pushing cutter head 420 and the cutting cutter head 230, the raw material sample to be processed is fixed in the circular space composed of the pushing groove 421 and the cutting groove 231. When the raw material sample to be processed is cut off, one side of its cutting surface will not warp to form a slope, ensuring the flatness of the cutting surface of the raw material sample to be processed.

[0068] It should be noted that when an element is described as "connected", "coupled" or "linked" to another element, it may mean a direct connection, coupling or linkage, but it should be understood that there may be intermediate elements between the two; that is, it covers both direct and indirect connection positional relationships.

[0069] It should also be noted that the use of words such as "a" or "an" does not necessarily imply a limitation in quantity. Words such as "comprising" or "including" mean that the elements or items appearing before the word cover the elements or items listed after the word and their equivalents, without excluding other elements or items.

[0070] It should be noted that terms indicating orientation or positional relationships such as "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, which are for the convenience of describing the present utility model, rather than meaning that the device or element must have a specific orientation, be constructed and operated in a specific orientation; when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0071] The preferred embodiments for implementing the present utility model have been described in detail above, but it should be understood that the functions of these embodiments are only for illustration and not for limiting the scope, application or construction of the present utility model in any way. The protection scope of the present utility model is defined by the appended claims and their equivalents.
