Description

Technical Field

[0001] The invention relates to the field of cutting technology, in particular to a multi-wire cutting machine for NdFeB processing. Background Art

[0002] Multi-wire cutting machines are often used in the processing of NdFeB magnets. Multi-wire cutting machines are a new type of cutting method that uses high-speed reciprocating motion of metal wires to cut materials into hundreds of thin slices at a time. CNC multi-wire cutting machines based on high-precision, high-speed and low-loss cutting control can fully achieve high-precision, high-speed and low-loss cutting of materials;

[0003] However, when cutting tubular magnetic bodies, the existing multi-wire cutting machines must, after fixing the magnets, cut a stroke of at least the diameter of the tubular magnetic body in order to cut the magnetic body blank into multiple pieces of products. However, this processing method not only leads to a long processing time, but also fails to effectively limit the products after being cut into multiple pieces. In the process of final cutting, it is very easy to cause cracking at the cutting point, affecting the cutting quality. Furthermore, when cutting large-diameter tubular magnetic bodies, due to the factory settings of the multi-wire cutting machine, it is often impossible to cut the tubular magnetic body because the cutting spacing is smaller than the diameter of the tubular magnetic body. Even when cutting with a multi-wire cutting machine with adjustable cutting spacing, it is necessary to adjust the length of the metal wire according to the cutting spacing. However, longer metal wires will have the problem of difficulty in controlling tension, because the wires with longer spacing are prone to unstable tension due to vibration or material stress changes, thereby affecting the cutting effect and making it impossible to guarantee the final processing quality.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] See also Figures 1 to 9 As shown: A multi-wire cutting machine for NdFeB processing, comprising a cutting module 1, an axial adjustment module 2 arranged below the cutting module 1 and a longitudinal support module 3 arranged in the middle of the axial adjustment module 2; the axial adjustment module 2 is provided with a plurality of adjustment points that can approach or move away from each other; the longitudinal support module 3 is vertically arranged at the adjustment points and a plurality of groups of adjustment points are provided in a one-to-one correspondence; the end of the axial adjustment module 2 is also provided with a rotary drive module 4 that can drive the axial adjustment module 2 to rotate circumferentially.

[0034] When it is necessary to cut the tubular magnetic body, the staff first manipulates the axial adjustment module 2 to move so that the multiple groups of adjustment points on the axial adjustment module 2 slide toward each other. Since the longitudinal support module 3 is vertically arranged at the adjustment point, when the position of the adjustment point changes, the longitudinal support module 3 will change synchronously with the change of the adjustment point, thereby achieving the purpose of freely adjusting the support point of the tubular magnetic body during cutting according to the cutting requirements; after the longitudinal support module 3 slides to the corresponding support position with the change of the adjustment point, the tubular magnetic body to be cut is coaxially sleeved and installed outside the axial adjustment module 2, and then the longitudinal support module 3 is driven to move, and the longitudinal support module 3 is used to radially support the tubular magnetic body from the inside until it is coaxially arranged with the circumferential adjustment module; finally, the cutting module 1 is driven to move downward longitudinally to cut the tubular magnetic body, and the downward movement height is only greater than the thickness of the tubular magnetic body; the tubular magnetic body is continuously driven by the rotary drive module 4 during the cutting process until the cutting of the tubular magnetic body is completed.

[0035] See also Figure 6 and Figure 8 As shown: the axial adjustment module 2 also includes a plurality of groups of folding units 21 and a plurality of groups of guiding units 22 capable of longitudinally guiding the plurality of groups of folding units 21; the plurality of groups of folding units 21 are hinged at their ends, and the hinges constitute the adjustment points; the plurality of groups of guiding units 22 are also provided with a first guiding rod 23 and a second guiding rod 24 capable of respectively connecting in series the upper guiding ends and the lower guiding ends of the plurality of groups of guiding units 22; the proximal ends of the first guiding rod 23 and the second guiding rod 24 are both arranged through the rotary drive module 4, and are adjusted and controlled by the adjustment unit 25 arranged on the rotary drive module 4; the folding unit 21 is composed of a first connecting rod 212 and a second connecting rod 213 hinged at the middle through a first hinge portion 211.

[0036] Since the folding unit 21 is composed of a first connecting rod 212 and a second connecting rod 213 which are hinged in the middle through a first hinge portion 211 and are arranged in an X shape; when multiple groups of folding units 21 are hinged end to end, there are upper hinge points and lower hinge points, and accordingly the adjustment points are also divided into upper adjustment points and lower adjustment points;

[0037] The guide unit 22 is used to longitudinally guide the upper hinge point and the lower hinge point of the multiple groups of folding units 21, so as to ensure that when the multiple groups of folding units 21 are folding, under the guidance of the guide unit 22, the upper hinge point and the lower hinge point can only be longitudinally close to or far away from each other, so as to ensure that in the adjustment state, the multiple groups of adjustment points are adjusted and set in a unified posture; and because the upper guide ends and the lower guide ends of the multiple groups of guide units 22 are respectively arranged in series through the first guide rod 23 and the second guide rod 24; when it is necessary to adjust the spacing between the multiple groups of adjustment points, the adjustment unit 25 adjusts the spacing between the first guide rod 23 and the second guide rod 24 in opposite directions, so as to achieve the effect of controlling the linkage folding of the multiple groups of folding units 21; and accordingly, the effect of adjusting the spacing between the hinge points of the adjustment points of the multiple groups of folding units 21 is achieved.

[0038] See also Figure 7 As shown: the guide unit 22 is composed of a sleeve 221 and a telescopic rod 222 that slide together with each other. The sleeve 221 and the telescopic rod 222 are respectively hinged to the first connecting rod 212 and the second connecting rod 213 through a second hinged portion 223 arranged near the rear end of the first connecting rod 212 and the rear end of the second connecting rod 213, so as to realize longitudinal guidance between the rear end of the first connecting rod 212 and the rear end of the second connecting rod 213 in the adjustment state; the second hinged portion 223 is hinged to the connecting rod through a hinge shaft 224 arranged near one side of the connecting rod; and a first through hole 225 is radially penetrated outside the second hinged portion 223.

[0039] The first guide rod 23 and the second guide rod 24 respectively connect the plurality of sleeves 221 and the telescopic rods 222 in series through the first through holes 225 formed outside the second hinged portion 223;

[0040] Since the first guide rod 23 and the second guide rod 24 respectively set multiple groups of sleeves 221 and telescopic rods 222 in series through the first through holes 225 opened outside the second hinged part 223; when the first guide rod 23 and the second guide rod 24 approach each other under the adjustment of the adjustment unit 25; the sleeve 221 and the telescopic rod 222 can only be matched in a longitudinal sliding manner, thereby driving the rear end of the first connecting rod 212 and the rear end of the second connecting rod 213 to only approach each other in the longitudinal direction; there will be no offset phenomenon, thereby ensuring precise adjustment between the adjustment points in the adjustment state, so that the adjustment points after adjustment are all equidistantly arranged.

[0041] See also Figure 4 and Figure 8 As shown: the first guide rod 23 and the second guide rod 24 are coaxially fixedly provided with a limiting portion 231 in the middle thereof; the limiting portion 231 is used to fix the first connecting rod 212 and the second connecting rod 213 to the guide module.

[0042] The limiting parts 231 fixedly arranged in the middle of the first guide rod 23 and the second guide rod 24 are used to fix the first connecting rod 212, the second connecting rod 213 and the guiding unit 22 used to guide the middle of the multiple groups of folding units 21; thereby, when the spacing between the first guide rod 23 and the second guide rod 24 is adjusted by operating the adjusting unit 25, so as to adjust the spacing between the adjustment points, the folding unit 21 at the center of the multiple groups of folding units 21 hinged at the head and tail is taken as the starting point, and the folding units 21 are unfolded and folded towards each other; in this way, in the subsequent cutting process, only the folding unit 21 at the center is taken as the origin, and the tubular magnetic body can be quickly positioned when it is installed.

[0043] See also Figure 5 and Figure 8 As shown: the adjustment unit 25 is composed of an upper sliding frame 251 and a lower sliding frame 252 arranged relative to the upper sliding frame 251, and a first driving rod 253 for synchronously driving the upper sliding frame 251 and the lower sliding frame 252 to move toward each other; the upper sliding frame 251 and the lower sliding frame 252 are also respectively penetrated by second through holes for the first guide rod 23 and the second guide rod 24 to pass through; the upper sliding frame 251 and the lower sliding frame 252 are also respectively provided with locking members 254 for limiting and locking the first guide rod 23 and the second guide rod 24.

[0044] When it is necessary to adjust the distance between the upper sliding frame 251 and the lower sliding frame 252 towards each other, so as to achieve equidistant adjustment of the distance between multiple groups of adjustment points, the first driving rod 253 is first driven to move. The first driving rod 253 is a bidirectional screw. When the first driving rod 253 is in a rotating state, it uses its own two threaded segments to drive the upper sliding frame 251 and the lower sliding frame 252 to move synchronously, thereby achieving the effect of driving the upper sliding frame 251 and the lower sliding frame 252 to move closer or farther away from each other, thereby achieving the adjustment of the distance between the upper sliding frame 251 and the lower sliding frame 252.

[0045] See also Figure 6 As shown, the longitudinal support module 3 includes a supporting unit 31 which can radially approach or move away from the inner wall of the tubular magnetic body and a driving unit 32 for driving the supporting unit 31 to move radially.

[0046] The supporting unit 31 is slidably arranged in a vertical state in a slide groove 226 which radially penetrates and is opened outside the hinge shaft 224; when the supporting unit 31 is moved to the supporting point under the adjustment of the axial adjustment module 2, when it is necessary to radially support the tubular magnetic body located at this point, it is only necessary to connect an external power supply to drive the driving unit 32 to operate, and the driving unit 32 drives the supporting unit 31 to operate, so that the supporting end of the supporting unit 31 is radially arranged close to the inner wall of the tubular magnetic body until the supporting end of the supporting unit 31 conflicts with the inner wall of the tubular magnetic body, thereby achieving the internal support effect on the tubular magnetic body.

[0047] See also Fig. 9 As shown: the supporting unit 31 includes a supporting member 311 and a mounting seat 312 for mounting the supporting member 311; a guide rod 313 capable of radially guiding the mounting seat 312 is vertically arranged at the bottom of the mounting seat 312; the mounting seat 312 is hinged to the driving end of the driving unit 32 through the guide.

[0048] The supporting units 31 are arranged in two groups, respectively arranged above and below the driving unit 32;

[0049] The guide rod 313 is slidably disposed in a vertical state in a slide groove 226 that radially penetrates and is opened outside the hinge shaft 224; so that when the guide rod 313 is driven by the driving unit 32, the guide rod 313 can only slide back and forth in a vertical state under the guidance of the slide groove 226;

[0050] The supporting member 311 is preferably a supporting rubber block, which can achieve flexible supporting of the tubular magnetic body without causing damage to the tubular magnetic body.

[0051] See also Fig. 9 As shown, an avoidance groove 3111 is also formed on the upper surface of the supporting member 311 .

[0052] The avoidance groove 3111 opened on the upper surface of the top support member 311 is a gap for the cutting line of the cutting module 1 to cut in; it ensures that the tubular magnetic body can be completely cut off by the cutting line while not cutting the top support member 311; and the axial length of the top support is preferably set to the maximum, so that after the tubular magnetic body is cut, the two ends of the top support member 311 can respectively support the two cut tubular magnetic bodies, so that the tubular magnetic body can also be effectively supported after being completely cut.

[0053] See also Figure 6 and Fig. 9As shown: the driving unit 32 includes a shaft rod 321 and a second driving rod 322 slidably arranged on the shaft rod 321; the second driving rod 322 is also threadedly provided with a slider 323 and a third connecting rod 324 hingedly arranged on the slider 323; the distal end of the third connecting rod 324 is hinged to the lower end of the guide rod 313.

[0054] The shaft rod 321 is also provided with a sliding groove that is slidably matched with the inner wall sliding strip of the second driving rod 322; so that when the shaft rod 321 rotates, the second driving rod 322 can be driven to rotate synchronously. The second driving rod 322 is also provided with a thread that is screwed to the slider 323;

[0055] When it is necessary to drive the supporting unit 31 to radially support the inner wall of the tubular magnetic body, the shaft rod 321 is first driven to rotate. The shaft rod 321 drives the second driving rod 322 and the slider 323 screwed on the outside of the second driving rod 322 to move in turn in the rotating state. Finally, under the drive of the third connecting rod 324, the supporting unit 31 is driven to be radially close to the tubular magnetic body, thereby realizing the supporting work of the tubular magnetic body.

[0056] See also Figure 1 and Figure 3 As shown, the rotation drive module 4 includes a limit plate 41 and a servo motor 42 for driving the limit plate 41 to rotate; the servo motor 42 is fixed to the frame through a mounting frame 43.

[0057] The limit frame is used to limit the installation of the first guide rod 23, the second guide rod 24 and the control unit; when it is necessary to drive the tubular magnetic body coaxially lifted by the axial adjustment module 2 and the longitudinal support module 3 to rotate and cut it by the cutting module 1, it is only necessary to connect an external power supply to drive the servo motor 42 to operate, and the output shaft of the servo motor 42 rotates to drive the limit frame to rotate, thereby achieving the effect of driving the tubular magnetic body to rotate.

[0058] The present invention can not only fully support and limit the tubular magnetic body, but also can self-adjust the cutting distance according to the cutting requirements, and the operation is simple and convenient; the cutting efficiency is high and the effect is good.

[0059] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
