[0021] See also Figure 1 as well as Figure 2The present embodiment provides a raw material cutting device for machining a seat ring of an engineering machinery, comprising a base plate 10, a transfer assembly 20, a cutting assembly 30, a fixing assembly 40 and an adjusting assembly 50. A support plate 101 is fixedly arranged on the upper part of the base plate 10. The transfer assembly 20 is arranged on the inner side of the support plate 101, and is used to transfer a plurality of rods to be cut to the cutting station in sequence. The cutting assembly 30 is arranged above the transfer assembly 20, and is used to cut a plurality of rods transferred to the cutting station, so that the rods are cut into a plurality of short materials.

The adjusting assembly 50 is arranged inside the transfer assembly 20, and is used to adjust the cutting assembly 30, so that the short materials cut by the cutting assembly 30 can present different lengths.

[0022] When it is necessary to cut the rods, several rods can be placed on the transfer assembly 20 in turn, and the transfer assembly 20 can be used to drive the several rods to rotate, and then the several rods can be transferred to the cutting station in turn. When a group of rods is transferred to the cutting station, the cutting assembly 30 is used to cut the rods, so that the rods are cut into several short pieces. In the above-mentioned process of cutting and cutting the rods by the cutting assembly 30, the fixing assembly 40 is used to fix the rods, so as to improve the stability of the rods when they are cut, thereby improving the cutting effect, and when the required short material length changes, the adjusting assembly 50 can be used to adjust the cutting assembly 30, so that the length of the short material after cutting by the cutting assembly 30 changes, so as to meet the processing requirements of engineering machinery seat rings of different specifications.

[0023] See also Figure 1 In one embodiment, the cutting assembly 30 includes a motor 301, a rotating shaft 303 and a cutting wheel 304. The motor 301 is fixedly mounted on the side wall of the bracket plate 101. One end of the rotating shaft 303 is connected to the output end of the motor 301, and the other end extends to the inner side of the bracket plate 101 and rotates with the inner wall of the bracket plate 101. The cutting wheel 304 is provided with a plurality of groups, and a plurality of the cutting wheels 304 are mounted on the outside of the rotating shaft 303 and are distributed in sequence at equal intervals along the length direction of the rotating shaft 303.

[0024] When the transfer assembly 20 transfers a group of bar materials to the cutting station, the motor 301 drives the rotating shaft 303 to rotate, thereby driving the plurality of cutting wheels 304 to rotate. The plurality of cutting wheels 304 act on the bar materials when rotating, thereby cutting the bar materials into a plurality of short materials.

[0025] See also Figure 1 , Figure 2 as well as Figure 3In one embodiment, a second gear 302 is fixedly provided on the outside of the rotating shaft 303, and the transfer assembly 20 includes a rotating drum 201 and a supporting ring 202. The rotating drum 201 is arranged below the rotating shaft 303 and is parallel to the rotating shaft 303. A group of end drums 203 are fixedly provided at opposite ends of the rotating drum 201. One end of the two groups of end drums 203 away from the rotating drum 201 is rotatably matched with the bracket plate 101. A first gear 208 is fixedly provided on the outside of one group of end drums 203. The first gear 208 is meshed with the second gear 302. The supporting ring 202 is provided with a plurality of groups, and a plurality of the supporting rings 202 are installed in the On the outside of the drum 201 and distributed in sequence at equal intervals along the length direction of the drum 201, an annular groove 2021 is opened on the circumferential outer wall of each group of the supporting rings 202, and the annular groove 2021 is concentrically arranged with the supporting ring 202. A plurality of grooves 2022 are opened on the circumferential outer wall of each group of the supporting rings 202, and the plurality of grooves 2022 are distributed in a circular array with respect to the supporting ring 202, and a plurality of mutually connected channels are formed between the plurality of grooves 2022 on the plurality of the supporting rings 202, and a plurality of the cutting wheels 304 correspond one-to-one to a plurality of the supporting rings 202, and the lower portion of each group of the cutting wheels 304 extends into a group of the annular grooves 2021.

[0026] When the motor 301 drives the rotating shaft 303 to rotate and then drives the cutting wheels 304 to rotate, the rotating shaft 303 can also drive the second gear 302 to rotate, and the meshing action of the second gear 302 and the first gear 208 drives the end tube 203 to rotate, and the end tube 203 drives the rotating cylinder 201 and the supporting rings 202 to rotate. When the supporting rings 202 rotate, the lower parts of the cutting wheels 304 rotate inside the annular grooves 2021, and the supporting rings 202 drive the channels to rotate. When a channel rotates to an obliquely upward position, the staff places a bar inside the channel, and the bar follows the supporting rings 202. And the drum 201 rotates upward synchronously, and then when a subsequent channel rotates to an obliquely upward position, the staff again places a subsequent bar in the subsequent channel, and the subsequent bar follows the supporting rings 202 and the drum 201 and rotates upward synchronously again, and this reciprocating cycle is repeated. The drum 201 and the supporting rings 202 can realize the continuous transfer of a plurality of bars. When a certain bar rotates to a position directly above the drum 201 (i.e., the aforementioned cutting station), a plurality of cutting wheels 304 rotating in the annular groove 2021 act on the bar, and then cut the bar, so that the bar is cut into a plurality of short bars.

[0027] See also Figure 2 , Figure 4 as well as Figure 7In one embodiment, a plurality of stoppers 207 are fixedly arranged on the circumferential side wall of the rotating drum 201, and the plurality of stoppers 207 correspond to the plurality of channels one by one, and the plurality of stoppers 207 are correspondingly arranged at one end of the plurality of channels, and the fixing assembly 40 comprises a first threaded sleeve 401, a screw rod 402, an outer ring plate 403, a third gear 405 and a first arc-shaped rack 406, and the first threaded sleeve 401 is provided with a plurality of groups, and the plurality of first threaded sleeves 401 correspond to the plurality of channels one by one, and the plurality of first threaded sleeves 401 is correspondingly arranged at the other end of several of the channels, one end of each group of the first threaded sleeves 401 is threadedly matched with a group of the screw rods 402, and one end of each group of the screw rods 402 away from the corresponding first threaded sleeves 401 is fixedly provided with a group of the third gears 405, the outer ring plate 403 is sleeved on the outside of the rotating cylinder 201, the first arc-shaped rack 406 is fixedly provided on the inner wall of the outer ring plate 403, and the third gear 405 is located on the inner side of the outer ring plate 403 and can engage with the first arc-shaped rack 406.

[0028] When a bar is placed in the corresponding channel and rotates upward with the rotating drum 201 and the supporting rings 202, the third gear 405 corresponding to the other end of the channel and the first arc-shaped rack 406 on the inner wall of the outer ring plate 403 enter into a meshing state, and the first arc-shaped rack 406 drives the third gear 405 to rotate, thereby driving the corresponding screw 402 to rotate. When the screw 402 rotates, it cooperates with the thread of the corresponding first threaded sleeve 401 to drive the first threaded sleeve 401 to move toward the channel. The sleeve 401 acts on one end of the bar material, thereby applying a supporting force to the one end of the bar material, so that the other end of the bar material is supported on the corresponding stop seat 207, thereby realizing the supporting and fixing of the bar material. When the bar material is supported and fixed, as the third gear 405 disengages from the first arc-shaped rack 406, the corresponding screw 402 no longer rotates, and the corresponding first threaded sleeve 401 no longer moves, so that the bar material maintains a fixed state and rotates to a position above the rotating drum 201, and is then cut into several short pieces by the rotating cutting wheels 304.

[0029] See also Figure 2 as well as Figure 4 In one embodiment, an inner ring plate 407 is further sleeved on the outside of the rotating drum 201, and the inner ring plate 407 is located between the third gear 405 and the rotating drum 201.

[0030] After a certain bar is cut into several short pieces by several cutting wheels 304, as the rotating drum 201 and several supporting rings 202 continue to rotate, several short pieces are driven by several supporting rings 202 to rotate downward, at this time, the third gear 405 is meshed with the second arc-shaped rack 409, and the second arc-shaped rack 409 drives the third gear 405 to rotate in the opposite direction, thereby driving the screw 402 to rotate in the opposite direction, and when the screw 402 rotates in the opposite direction, it drives the first threaded sleeve 401 away from the channel through the reverse thread cooperation with the first threaded sleeve 401, thereby resetting the first threaded sleeve 401, so that when the third gear 405 rotates to mesh with the first arc-shaped rack 406 in the future, it can drive the first threaded sleeve 401 to approach the channel again, thereby continuing to support and fix the subsequent bar materials; when several short pieces are driven by several supporting rings 202 to rotate downward to the obliquely downward position, several short pieces lose their supporting and fixing function, and therefore, several short pieces automatically fall from the corresponding channels, thereby realizing automatic discharge of the short pieces.

[0031] See also Figure 4 In one embodiment, a plurality of guide rails 204 are fixedly provided on the circumferential side wall of the rotating drum 201, and the plurality of guide rails 204 correspond one-to-one to the plurality of first threaded sleeves 401. A group of slide seats 408 are fixedly provided on the side wall of each group of the first threaded sleeves 401, and one end of each group of the slide seats 408 away from the corresponding first threaded sleeve 401 is slidably matched with a group of the guide rails 204. A plurality of support seats 205 are also fixedly provided on the circumferential side wall of the rotating drum 201, and the plurality of support seats 205 correspond one-to-one to the plurality of screw rods 402. Each group of the screw rods 402 passes through a group of the support seats 205 and rotates with the support seats 205.

[0032] Through the sliding cooperation between the slide seat 408 and the guide rail 204 and the rotational cooperation between the support seat 205 and the screw 402, when the third gear 405 is engaged with the first arc-shaped rack 406 and the second arc-shaped rack 409, the screw 402 can smoothly drive the first threaded sleeve 401 to move, thereby providing stable support for the bar material and realizing the smooth resetting of the first threaded sleeve 401.

[0033] See also Figure 6In one embodiment, a plurality of the cutting wheels 304 are slidably matched with the rotating shaft 303, a slide groove 206 is provided on the circumferential side wall of the rotating cylinder 201, and the slide groove 206 is distributed along the length direction of the rotating cylinder 201, and the adjusting assembly 50 includes an adjusting rod 501 and a second threaded sleeve 503, one end of the adjusting rod 501 extends into the interior of the rotating cylinder 201 and is distributed along the axis of the rotating cylinder 201, and the other end passes through the interior of the end cylinder 203 and extends to the outside of the end cylinder 203, and a plurality of threaded segments 502 are provided on the outside of the adjusting rod 501, and the plurality of threaded segments 502 are distributed in sequence at intervals on the outside of the adjusting rod 501, and the plurality of threaded segments 502 The pitch of the thread increases successively along the length direction of the adjusting rod 501, and the second threaded sleeve 503 is provided with several groups. The second threaded sleeve 503, the threaded section 502 and the supporting ring 202 are the same in number and correspond one to one. Several second threaded sleeves 503 are sleeved on the outside of the adjusting rod 501 and are threadedly matched with the adjusting rod 501 through several threaded sections 502. A group of connecting rods 504 are fixedly provided on the side wall of each group of the second threaded sleeves 503. One end of several connecting rods 504 away from the corresponding second threaded sleeve 503 extends from the slide groove 206 to the outside of the rotating cylinder 201 and is fixedly connected to several supporting rings 202.

[0034] If the length of the short material cut by the current plurality of cutting wheels 304 is 3 cm, the distance between the two adjacent groups of cutting wheels 304 is also 3 cm. When the required length of the short material changes, for example, when the required length of the short material changes from 3 cm to 4 cm, the staff can rotate the adjusting rod 501 one circle. When the adjusting rod 501 rotates one circle, the plurality of second threaded sleeves 503 are driven to move along the length direction of the adjusting rod 501 through the thread cooperation of the plurality of threaded segments 502 and the plurality of second threaded sleeves 503. When the plurality of second threaded sleeves 503 move, the plurality of supporting rings 202 are driven to move along the length direction of the rotating drum 201 through the plurality of connecting rods 504. Since the lower parts of the plurality of cutting wheels 304 extend into the annular grooves 2021 on the plurality of supporting rings 202, the plurality of supporting rings 202 can clamp the plurality of cutting wheels 304 when they move so that A plurality of cutting wheels 304 slide synchronously along the outside of the rotating shaft 303, and when a plurality of thread segments 502 rotate one circle, since the pitch of the plurality of thread segments 502 increases successively along the length direction of the adjusting rod 501, when the plurality of thread segments 502 rotate one circle and thereby drive a plurality of supporting rings 202 to move, the distance between two adjacent groups of supporting rings 202 increases successively, that is, a supporting ring 202 at the edge moves 1 cm, the supporting ring 202 adjacent to it moves 2 cm, and the subsequent adjacent supporting ring 202 moves 3 cm... and so on. After the adjusting rod 501 rotates one circle, the spacing between the plurality of cutting wheels 304 that follow the plurality of supporting rings 202 to slide along the outside of the rotating shaft 303 is changed from 3 cm to 4 cm, thereby completing the equidistant adjustment of the plurality of cutting wheels 304, and then equidistantly changing the length of the short material after cutting.

[0035] See also Figure 2 In one embodiment, a hand wheel 505 is fixedly provided at one end of the adjusting rod 501 located outside the end tube 203. Through the setting of the hand wheel 505, the adjusting rod 501 can be flexibly rotated, and then the spacing between the plurality of cutting wheels 304 can be flexibly adjusted.

[0037] When the motor 301 drives the rotating shaft 303 to rotate, the rotating shaft 303 can smoothly drive the sliding sleeve 305 and the cutting wheel 304 to rotate through the cooperation between the key 307 and the key slot, thereby smoothly cutting and truncating the bar material transferred to the cutting station.

[0038] See also Figure 5 In one embodiment, a locking bolt 306 is provided on the sliding sleeve 305 .

[0039] The locking bolt 306 can be turned in the opposite direction to allow the locking bolt 306 to be screwed into the sleeve 305 and then supported on the outer wall of the shaft 303, thereby fixing the sleeve 305 and the cutting wheel 304, so that the shaft 303 can smoothly drive the cutting wheel 304 to rotate, thereby achieving smooth cutting and cutting of the bar material.
