After the saw chain is loaded on the saw chain, a fluid can be introduced into the first opening 211 and sprayed onto the cutter head 1 through the second opening 221. The fluid can be compressed air and / or oil, so as to cool and / or lubricate the cutter head 1.

[0028] The initial middle guide tooth 2 is firstly formed by stamping, and then a groove is formed along the outer wall of the middle guide tooth 2, thereby connecting the tooth cutting portion 21 and the guide knife portion 22, and then a sealing plate is welded on the outside of the guide groove, and a first opening 211 is left in the tooth cutting portion 21, and a second opening 221 is left in the recess behind the guide knife portion 22, thereby realizing the above-mentioned processing of the middle guide tooth 2.

[0029] At the same time, the above-mentioned middle guide tooth 2 can also be processed by precision casting technology, but the production cost of precision casting is relatively high, so it is not applicable. Therefore, it is more appropriate to obtain the above-mentioned product by cutting and welding after stamping. Therefore, the following device is designed specifically for producing the above-mentioned middle guide tooth 2.

[0030] The production equipment of the saw chain includes a main frame 3, on which a positioning portion 31 for positioning and installing a middle guide tooth 2 is provided.

[0032] When the winding motor 4231 is not winding, under the action of the elastic member 4233, the roller in front of the sliding member 4221 touches the front end wall of the track rail 421. After the winding motor 4231 rotates, the winding rope 4232 is tightened, thereby pulling the sliding member 4221 to slide along the track rail 421.

[0033] The cutting and sealing unit 41 includes an integrated shaft 413, a driving motor 415 and a clutch 416. The integrated shaft 413 is rotatably and slidably arranged on the upper mounting frame 4222, and a cutting blade 411 is arranged at the upper end of the integrated shaft 413, and a roll welding roller 412 is arranged below the cutting blade 411, so that the integrated shaft 413 is integrated with a cutting tool for cutting grooves and a welding tool for roll welding, and a transmission member 414 is arranged at the lower end of the integrated shaft 413. 414 is a polygonal shaft, the driving motor 415 is fixedly arranged on the mounting frame 4222 of the lower layer, and a polygonal groove body adapted to the transmission member 414 is opened at the center of the driving shaft of the driving motor 415, the clutch member 416 is a lifting member, and the lifting member can be a pneumatic lifting cylinder or an electric lifting cylinder, and an annular groove 4131 is arranged on the integrated shaft 413, and a ring sleeve 4161 is arranged on the telescopic rod head of the clutch member 416, and the ring sleeve 4161 is clamped on the annular groove 4131, so as to The clutch 416 is extended and retracted to drive the integrated shaft 413 to move up and down, and the integrated shaft 413 moves downward, and the transmission member 414 at the lower end enters the driving shaft of the driving motor 415. At this time, the driving motor 415 rotates to drive the integrated shaft 413 to rotate together, so that the cutting blade 411 rotates, and at this time, the cutting blade 411 is located at the height of the side of the middle guide tooth 2, and the cutting blade 411 can perform a groove operation on the middle of the side of the middle guide tooth 2. The clutch 416 rises upward, driving the integrated shaft 413 to move upward, so that the transmission member 414 leaves the driving motor 415, and then the transmission between the two is disconnected. At this time, the roll welding roller 412 is located at the height of the side of the middle guide tooth 2, and an electrode contact plate is provided on the lower end surface of the upper end mounting frame 4222. The clutch 416 drives the integrated shaft 413 to move upward, so that the upper end surface of the boss with the annular groove 4131 is topped on the electrode contact plate, so that the roll welding roller 412 is energized, and then the roll welding roller 412 can perform a roll welding operation.

[0034] A limiting truncated cone 4111 is provided on the upper end of the cutting disc 411. When the grooving operation is performed, the cutting disc 411 rotates, and the sliding member 4221 slides on the track track 421. Initially, the cutting disc 411 does not contact the middle guide tooth 2. After moving a certain distance, it starts to cut the outer wall of the middle guide tooth 2. After the peripheral wall of the limiting truncated cone 4111 touches the outer wall of the middle guide tooth 2, the outer wall of the middle guide tooth 2 starts to be grooved with equal depth. At this time, the peripheral wall of the limiting truncated cone 4111 touches the outer wall of the middle guide tooth 2, and cooperates with the elastic sliding mounting frame 4222 to ensure that the cutting depth of the cutting disc 411 is consistent during the entire cutting process except the initial section. At the same time, it can also offset the change in the spacing between the sliding member 4221 and the outer wall of the middle guide tooth 2 during the sliding process on the track track 421, thereby ensuring that the depth of the cutting groove on the middle guide tooth 2 remains consistent.

[0035] After the cutting is completed, the winding motor 4231 stops running, and the sliding member 4221 returns to the initial state under the action of the elastic member 4233. When returning to the initial position, the cutting blade 411 does not contact the middle guide tooth 2, and then the clutch member 416 extends out at this time, so that the cutting blade 411 can rise without interference, and at the same time, the rolling welding roller 412 rises to the same height as the middle guide tooth 2. After the rolling welding roller 412 rises, the rolling welding roller 412 is powered on.

[0036] The clamping unit 43 includes a telescopic part, and a suction cup is arranged at the front end of the telescopic part. A manipulator, an automatic loader or a manual operation sends the sealing plate to the suction cup at the front end of the telescopic part, and the suction cup absorbs the sealing plate. The sealing plate is a plate formed according to the shape of the side wall of the middle guide tooth 2. The sealing plate is located on one side of the cutting groove body of the middle guide tooth 2. When the clutch part 416 extends upward, the telescopic part of the clamping unit 43 also extends forward at the same time, so that the sealing plate is pressed against the groove body, thereby covering the cutting groove in the middle part of the middle guide tooth 2.

[0037] At this time, the winding motor 4231 works again, pulling the sliding part 4221 to move on the track track 421, and the rolling welding roller 412 is pressed against the side wall of the middle guide tooth 2. After pressing against the sealing plate, the sealing plate is roll-welded to the side wall of the middle guide tooth 2. When the sealing plate is partially welded, the suction cup on the clamping unit 43 is released, and the telescopic part retracts, thereby removing the obstruction to the moving path of the rolling welding roller 412, and then the rolling welding roller 412 completes the welding of the sealing plate. After the welding is completed, the first opening 211 and the second opening 221 are respectively left at the head and tail ends of the cutting groove, and the first opening 211 and the second opening 221 are connected by a blocked cutting groove body. At this time, the processing of the middle guide tooth 2 is completed.

[0038] After the rolling welding is completed, the winding motor 4231 stops rotating, and the sliding member 4221 returns to its initial state under the action of the elastic member 4233. The clutch member 416 descends, and the integrated shaft 413 is combined with the driving motor 415 again and returns to its initial state. At this time, the suction cup on the middle guide tooth 2 drives the processed middle guide tooth 2 to leave the main frame 3.

[0039] The working principle or usage of saw chain production equipment is as follows: The middle guide gear 2 is moved from other positions to the positioning portion 31 of the main frame 3 by the suction cup, and the middle guide gear 2 is pressed downward by the suction cup, so that the middle island gear 2 is positioned and locked on the main frame 3.

[0040] The driving motor 415 starts to rotate, driving the cutting blade 411 to rotate, and at the same time the winding motor 4231 starts to rotate, pulling the sliding member 4221 to move on the track rail 421. When performing the grooving operation, the cutting blade 411 does not contact the middle guide tooth 2 at the beginning, and starts to cut the outer wall of the middle guide tooth 2 after moving a certain distance. After the peripheral wall of the limiting truncated cone 4111 touches the outer wall of the middle guide tooth 2, the outer wall of the middle guide tooth 2 starts to be grooved with equal depth. At this time, the peripheral wall of the limiting truncated cone 4111 touches the outer wall of the middle guide tooth 2, and cooperates with the elastic sliding mounting frame 4222 to ensure that the cutting depth of the cutting blade 411 is consistent during the entire cutting process except the initial section, and at the same time, it can also offset the change in the spacing between the sliding member 4221 and the outer wall of the middle guide tooth 2 during the sliding process on the track rail 421, ensuring that the depth of the cutting groove on the middle guide tooth 2 remains consistent.

[0041] After the cutting is completed, the winding motor 4231 stops running, and the sliding member 4221 returns to the initial state under the action of the elastic member 4233. When returning to the initial position, the cutting blade 411 does not contact the middle guide tooth 2, and then the clutch member 416 extends out at this time, so that the cutting blade 411 can rise up without interference, and at the same time, the rolling welding roller 412 rises to the same height as the middle guide tooth 2. After the rolling welding roller 412 rises, the rolling welding roller 412 is powered on.

[0042] The manipulator, automatic loader or manual labor delivers the blocking plate to the suction cup at the front end of the telescopic part, and the suction cup absorbs the blocking plate. When the clutch part 416 extends upward, the telescopic part of the clamping unit 43 also extends forward at the same time, so that the blocking plate is pressed against the groove body, thereby covering the cutting groove in the middle part of the middle guide tooth 2.

[0043] At this time, the winding motor 4231 works again, pulling the sliding part 4221 to move on the track track 421, and the rolling welding roller 412 is pressed against the side wall of the middle guide tooth 2. After pressing against the sealing plate, the sealing plate is roll-welded to the side wall of the middle guide tooth 2. When the sealing plate is partially welded, the suction cup on the clamping unit 43 is released, and the telescopic part retracts, thereby removing the obstruction to the moving path of the rolling welding roller 412, and then the rolling welding roller 412 completes the welding of the sealing plate. After the welding is completed, the first opening 211 and the second opening 221 are respectively left at the head and tail ends of the cutting groove, and the first opening 211 and the second opening 221 are connected by a blocked cutting groove body. At this time, the processing of the middle guide tooth 2 is completed.

[0044] After the rolling welding is completed, the winding motor 4231 stops rotating, and the sliding member 4221 returns to its initial state under the action of the elastic member 4233. The clutch member 416 descends, and the integrated shaft 413 is combined with the driving motor 415 again and returns to its initial state. At this time, the suction cup on the middle guide tooth 2 drives the processed middle guide tooth 2 to leave the main frame 3.

[0045] Embodiment 2:

[0046] See also Figure 1-Figure 5 and Figure 7 , Compared with the embodiment 1, the difference lies in the structure of the middle guide tooth 2 and the processing technology thereof, and the rest are the same.

[0047] A cutting groove is provided on the middle guide tooth 2, and an insert with a first opening 211 and a second opening 221 is embedded in the cutting groove. The insert can be installed in the cutting groove by welding or clamping. If it is installed by welding, the processing equipment and processing technology are the same as those in Example 1, except that the formed sealing plate adsorbed by the clamping unit 43 is changed into an insert. The clamping device 43 inserts the insert into the cutting groove when extending forward, and the rolling welding roller 412 rolls the insert and the cutting groove together when moving.

[0048] If the insert is inserted into the cutting groove by an over-fitting card, the clamping device 43 may not be able to completely embed the insert into the cutting groove when it is extended. At this time, the rolling welding roller 412 no longer performs power welding work, but performs rolling work to roll the insert into the cutting groove.
