The cutting wheel 2 is mounted on the cutting motor 7 and fixed to the feed guide 13. The feeding of the cutting machine is divided into manual cutting feeding and full-automatic cutting feeding. The utility model discloses in, thereby manual cutting off feed motion is through manual cutting off the last sector gear drive rack of control rod 21 and makes the guide pillar that feeds rise and do feed motion. The full-automatic cutting and feeding motion is to control and start the traction electromagnet 15 to work through the photoelectric length controller 8 of the control part; the feeding guide post is driven by the armature fixed plate 18 to ascend to perform feeding motion. The full automatic feed speed is controlled by means of a damping cylinder 4 arranged on the traction electromagnet 15.

4) The feed guide post performs feed motion or retreats, so that the shifting fork 24 pushes the connecting rod 1, the sliding rod 25 and the rubber plate 3 to complete automatic pushing work of the cut product; or withdrawn.

The structure of the multi-function cutting machine of the embodiment of the present invention is described below.

Referring to fig. 3 and 4, the cutting section of the cutter is composed of a cutting motor 7 and a cutting whetstone 2. The cutting wheel 2 is mounted on the cutting motor 7 and fixed to the feed guide 13. The feeding part of the cutting machine adopts two working modes of manual feeding and automatic feeding.

First, the manual feeding portion of the cutter will be described with reference to fig. 2. The manual feed portion is composed of a feed guide post 13 and a manual cut-off lever 21. The feeding guide post 13 is arranged in the feeding guide sleeve 20. The feeding guide sleeve 20 is provided with a hinge support, and a manual cutting operation rod 21 is fixed on the hinge support. The manual cut-off lever 21 is provided with a sector gear which is engaged with a rack on the feeding guide post 13. The manual feed is realized by moving down the manual cut lever 21 to raise the feed guide 13.

Referring again to fig. 2, the fully automatic feeding portion of the cutting machine will be described. The automatic feeding part consists of a feeding guide post 13, a traction electromagnet 15, an armature 16 and a damping cylinder 4. The traction electromagnet 15 is composed of an iron core and a coil; the armature 16 is located under the traction electromagnet 15 and at a distance from it and is fastened to the feed beam 13 by means of an armature fastening plate 18. The damping cylinder 4 is fixed on the feed guide sleeve 20 and is used for controlling the feed speed. The damping cylinder 4 is internally provided with a one-way damping piston 22 which is connected to the piston rod fixing frame 12 through a one-way damping piston rod. The other end of the piston rod holder 12 is connected to an armature 16. The damping cylinder 4 is connected with the traction electromagnet 15 through a screw rod.

Referring to fig. 1a and fig. 1b, the full-automatic cutting and feeding motion is to start the traction electromagnet 15 to work under the control of the photoelectric length controller 8 of the control part, and to drive the feeding guide post 13 to ascend to perform feeding motion through the armature fixing plate 18. The automatic feed speed is controlled by means of a damping cylinder 4 arranged in series on the traction electromagnet 15.

A one-way damping piston 22 is fitted inside the damping cylinder 4. When the piston moves upwards, it compresses the air in the damping cylinder 4, preventing the rising movement. The compressed air in the damping cylinder 4 is gradually reduced by leaking air under pressure from the fitting clearance of the damping cylinder 4 and the one-way damping piston 22, thus causing the one-way damping piston 22 to decrease in upward movement speed. The rate of rise is determined by the fit gap between the one-way damping piston 22 and the damping cylinder 4. Under the action of gravity, when the piston moves downwards, the check valve on the piston is opened by the negative pressure suction force of the damping cylinder 4, and the air is communicated and slides downwards freely.

Utility model people discover, in order to make the operation of cutter steady reliable, need the damping ratio of reasonable design damping cylinder. To this end, embodiments of the present invention provide a method for determining a damping ratio ζ of a damping cylinder:

in the formula, ζ₀The theoretical calculation value of the damping ratio of the damping cylinder is generally determined by searching the existing technical manual or standard; s is the actual stroke of the piston rod of the damping cylinder, s_maxDesigning a maximum allowable stroke for a piston rod of the damping cylinder; v is the actual designed maximum speed of the piston rod of the damping cylinder, v_maxIs the theoretical maximum allowable speed of the piston rod of the damping cylinder.

The embodiment of the utility model provides an in, damping cylinder damping ratio is owing to utilized the theoretical calculated value of damping ratio to adjust the damping cylinder damping ratio of confirming the actual adoption through the actual stroke of damping cylinder piston rod and the actual design maximum speed value of piston rod, can make the equipment operation of cutter more reliable and stable, the interference killing feature is strong.

Cutting off the automatic starting device of the motor:

referring to fig. 3, outside the feed guide 20, a stroke switch 17 is installed through a fixing plate. A feed guide 13 is mounted in the feed guide 20, and a cutting motor 7 is mounted on the upper end surface of the feed guide 13. The guide section of the feeding guide column 13 is provided with a sliding guide positioning key for controlling the circumferential position, and the sliding guide positioning key is also used as a travel switch striker 23. The travel switch striker 23 extends through the feed guide 20 and out of the feed guide 20. The exposed outer surface of the switch plunger 23 contacts the contact of the switch 17 in accordance with the position and shape of the switch required for operation.

When the feeding guide post 13 performs a feeding motion, the travel switch 17 is first activated by the travel switch plunger 23 to rotate the cut-off motor 7. When the cutting operation is finished and the feeding guide post 13 returns to the original position, the cutting motor 7 is automatically powered off due to the action of the travel switch striker 23 and the travel switch 17.

Automatic clamp and synchronous motion structure device of cutter:

referring to fig. 3, a feed guide post 13 is fitted into the feed guide 20. The upper end surface of the feeding guide column 13 is provided with a cutting motor 7. Referring to fig. 4, a grinding wheel guard is fixed to the front end cover of the cut-off motor 7, and a synchronous presser 14 is fixed to the outer side of the guard. The synchronous compressor 14 is composed of a fixed seat, a compression spring, a positioning screw, a compression slide rod and a compression rubber pad. A positioning pressure plate 6 is also fixed on the plate surface of the feeding guide sleeve 20 and corresponds to the pressing rubber pad of the synchronous pressing device 14. The product 0 passes through at a constant speed under the positioning press plate 6 and above the synchronous presser 14 before cutting.

The linear bearing 11 is fixed below the plate surface of the feed guide 20 through a bearing seat. The linear bearings 11 are fitted on the synchronization rail 9. The tail end of the synchronous guide rail 9 is provided with a compression spring, so that the cutting motor 7 is always in a working initial position. The synchronous guide rail 9 is fixed on the cutter supporting plate 10. When the feeding guide post 13 makes a feeding movement, the synchronous presser 14 moves upwards to press the pre-cut product 0 and the positioning press plate 6. Under the action of the pressing force, the product 0 before cutting in the continuous production movement pushes the positioning pressing plate 6, the synchronous pressing device 14, the linear bearing 11, the cutting grinding wheel 2, the cutting motor 7 and the product 0 before cutting to move synchronously at a constant speed through friction force.

The structure of the photoelectric length controller 8 for full-automatic cutting:

referring to fig. 5a and 5b, the photoelectric length controller 8 is assembled by a photoelectric length control stop 8-1 on a photoelectric length controller supporting plate 8-6 through a fixed support, and the extended compression position is controlled by a position-adjustable limiting hook 8-2 and a position-adjustable limiting pin 8-5. The photoelectric fixed-length block 8-1 is also provided with a light barrier 8-3, the support fixed on the photoelectric fixed-length device supporting plate 8-6 is also provided with a photoelectric generator 8-4, and the photoelectric fixed-length device 8 is also fixed on the feeding guide sleeve 20 through the photoelectric fixed-length device supporting plate 8-6.

When the produced product 0 before cutting off pushes the photoelectric fixed-length stop 8-1 to move forwards against the resistance of the spring, the light barrier 8-3 arranged on the photoelectric fixed-length stop also moves along with the photoelectric fixed-length stop. When the photoelectric generator 8-4 is in a working position, the limiting pin 8-5 blocks the photoelectric fixed-length stop 8-1 from advancing, and the traction electromagnet 15 is switched on through a photoelectric circuit to realize the working state required by switching off. The photoelectric length fixing device 8 and the feeding guide sleeve 20 are fixed together through a photoelectric length fixing device supporting plate 8-6. Due to the action of the positioning pins 8-5, the fixed length of the product 0 before cutting can be synchronously moved with the cutting machine.

It takes a few seconds at most from the start of the operation of the photovoltaic generator 8-4 to the start of the switching-off. During this time, a small length of the product is continuously produced, but this length is only the distance in which the cutter is pushed to move synchronously with the product 0 before cutting, and does not affect the length of the product 0' after cutting, because the relative position between the positioning pin 8-5 and the cutting whetstone 2 is adjusted to be constant in operation.

Automatic ejecting mechanism of product 0' after cutting off:

referring to fig. 6, on the feed guide 20 pallet, the push link 1 is fixed by a holder hinge. The long arm of the push connecting rod 1 is connected with a push sliding rod 25 through a connecting rod hinge. The push-out slide rod 25 is matched in the supporting plate guide sleeve for positioning, and the front end of the push-out slide rod 25 is matched with the push rubber plate 3 which can be deformed in a single direction. The front end of the short arm of the pushing connecting rod 1 is provided with a toggle pin. A shift fork 24 fixed on the end surface of the feed guide post 13 fitted in the feed guide bush 20 is in contact with a shift pin on the short arm of the push link 1.

When the feeding guide pillar 13 is in feeding motion upwards, the shifting fork 24 is driven to move upwards, the shifting fork 24 shifts the short arm of the pushing connecting rod 1 to rotate anticlockwise, the long arm of the pushing connecting rod 1 pulls the pushing sliding rod 25 to slide backwards, and the pushing rubber plate 3 is driven to cross the product 0 before cutting through the hinge and unidirectional deformation. That is, when the cutting work is finished, the rubber sheet 3 is pushed just to the ready position to push out the cut product 0'.

When the product 0' is cut off and falls on the pallet, the feeding guide post 13 slides downwards due to the self-weight, and drives the shifting fork 24 to drive the pushing connecting rod 1 to rotate clockwise. The pushing slide rod 25 drives the pushing rubber plate 3 to push out the cut product 0' to complete the whole work.

In order to ensure that the traction electromagnet 15 and the damping cylinder 4 are stressed reasonably when working, reduce the working resistance when the feeding guide pillar 13 rises, and simultaneously consider that the feeding guide pillar 13 can slide down smoothly after the cutting is finished, 4 weight balance spring devices 19 with adjustable force are arranged between the feeding guide sleeve 20 and the feeding guide pillar 13.

The manual full-automatic multifunctional cutting-off work comprises the following steps:

after the continuously produced pre-cut article 0 is formed from the article producing machine 26, the desired length of the article is achieved with a cutter.

Referring to fig. 4, the cutting machine is fixed on a feeding guide post 13 after a cutting grinding wheel 2 is mounted on a cutting motor 7. The feed guide post 13 is fixed on the synchronous guide rail 9 by a linear bearing 11 through a feed guide sleeve 20. The synchronous guide rail 9 is fixed on the cutter supporting plate 10. Referring to FIG. 1, cutter blade 10 is secured to an article producing fuselage 26.

Referring to fig. 2, when a semi-automatic cut of any length is manually made, the manual cut lever 21 is moved down to rotate the sector gear, and the feed guide 13 is raised by the rack formed on the feed guide 13.

Raising of the feed guide column 13: referring to fig. 3, first, the guide key fixed to the feeding guide post 13 simultaneously restricts the circular motion, and the trip switch striker 23 that starts the cut-off motor 7 activates the trip switch 17, so that the cut-off motor 7 automatically rotates.

Referring to fig. 4, when the manual cut lever 21 is continuously moved, the synchronized presser 14 fixed to the guard of the cutting grindstone 2 starts to clamp the pre-cut product 0 with the positioning platen 6. Under the action of traction force generated by continuously producing products, the product 0 before cutting pushes the cutting motor 7, and the cutting motor 7 and the product 0 before cutting automatically move synchronously under the action of the linear bearing 11 and the synchronous guide rail 9.

When the manual cut lever 21 is moved further downward, the cutting whetstone 2 is further moved upward until the cutting work is completed.

When the manual cut-off operating lever 21 is released, the cut-off motor 7 automatically returns to the original position due to the action of gravity, and the cut-off motor 7 is also automatically powered off to stop rotating.

Fork 24 fixed to the feed guide 13: referring to fig. 6, when the cutting motor 7 performs a feeding motion, the pushing link is pushed, the pushing slide bar 25 pushes the pushing rubber plate 3 to move backward, and the product 0 before cutting in the production movement is jumped over, and stands by.

When the cutting work is finished and the cutting motor 7 returns to the original position, the shifting fork 24 pushes the connecting rod 1 and the pushing slide rod 25 to push the rubber plate 3 to be scraped forwards, so that the cut product 0' is automatically pushed out of the machine and enters the product collecting box.

When the fixed length full-automatic cutting is required, referring to fig. 1, the position of the photoelectric fixed length device 8 is determined according to the length of the cut product 0'. After the photoelectric length fixing device 8 is assembled, referring to fig. 5, the positions of the photoelectric generator 8-4, the light barrier 8-3 and the limiting pin 8-5 are accurately adjusted and fixed according to the working requirement, the limiting hook 8-2 is adjusted, the position of the photoelectric length fixing block 8-2 is determined, the spring force is adjusted, and the cutting precision is ensured, so that the work can be carried out.

Before cutting, the product 0 touches the photoelectric fixed-length stop 8-1 under the action of the production traction force of the product, and overcomes the spring force, so that the light barrier 8-3 and the induction photoelectric generator 8-4 work through an electric system of a photoelectric circuit, and the traction electromagnet 15 works. The armature 16 of the electromagnet drives the armature fixing plate 18 and the feeding guide post 13 to move upwards, so that full-automatic feeding movement is realized.

In order to slow down the suction working speed of the traction electromagnet 15, an armature 16 of the electromagnet is arranged between the feeding guide post 13 and the feeding guide sleeve 20, and a damping cylinder 4 is connected in series through a piston rod fixing frame 12 in a stroke area passing through a coil of the traction electromagnet 15. That is, the feed deceleration is realized by the resistance generated by the compressed air of the one-way damping piston 22 connected when the traction electromagnet 15 operates. Practice proves that when the working stroke of the traction electromagnet 15 is 30 millimeters, the working requirement is completely met within the working movement time of the armature, the traction electromagnet can work smoothly, even in experimental work, the armature is attracted once, the maximum time can reach 6 seconds, the repeated work is normal, the temperature is normal, and no heat is generated.

When the automatic cutting operation is finished, the cut product 0' is separated from the photoelectric fixed-length stop block 8-1, the light barrier 8-3 is separated from the photoelectric generator 8-4 under the action of the spring force, and the traction electromagnet 15 is powered off; under the action of the dead weight, the cut-off motor 7 is retracted to the home position. Other work contents are the same as manual semi-automatic cutting, and are not described in detail.
