The oil mist (grease) lubrication system is used for lubricating each connection part of the wire cutting machine. The operation platform 6 is arranged around the outside of the outer frame 2, and operators can stand on the operation platform 6 for operation or maintenance. The outer protective part 7 wraps around the outside of the outer frame 2 and is used for waterproof protection and safety shielding of the whole machine, etc.

[0043] The foundation pre-buried assembly 1 of this embodiment is the basic support base of this wire cutting machine. As Figure 3 shown, the foundation pre-buried assembly 1 includes a reinforced concrete 1.1, an equipment pre-buried installation plate 1.2, a current collecting drainage ditch 1.3, a loading and unloading track 1.4, and a loading and unloading trolley 1.5. The equipment pre-buried installation plate 1.2 is designed according to the installation requirements at the bottom of the outer frame 2 and is fixed on the work site through the reinforced concrete 1.1 for carrying this wire cutting machine. The current collecting drainage ditch 1.3 is arranged around the equipment pre-buried installation plate 1.2 to realize the functions of cutting fluid reflux collection and pumping and discharging. Two loading and unloading tracks 1.4 are installed in parallel above the middle of one side of the equipment pre-buried installation plate 1.2, and the loading and unloading trolley 1.5 travels along the loading and unloading track 1.4 for carrying materials in and out of the material table 3.9.

[0044] The peripheral columns of the peripheral frame 2 are fixed on the equipment embedded installation plate 1.2, playing the main load-bearing role of the peripheral frame 2. The outer protective part 7 is wrapped outside the peripheral frame 2, and the outer protective part 7 includes structures such as sheet metal parts, connecting parts, curtain guards, and enclosures.

[0045] The lifting and feeding table system 3 of this embodiment is as Figure 4 shown and includes lifting columns 3.1, lifting cross beams 3.2, materials 3.3, lifting transmission shafts 3.4, lifting screw bases 3.5, lifting drive reduction motors 3.6, lifting screws 3.7, table lifting seats 3.8, material tables 3.9, and baffles 3.10.

[0046] Lifting brackets are symmetrically installed on both sides of the loading and unloading track 1.4 on the equipment embedded installation plate 1.2. The lifting brackets are gantry structures composed of two lifting columns 3.1 and a lifting cross beam 3.2. Inside the peripheral frame 2, the two lifting columns 3.1 are respectively fixed on the equipment embedded installation plate 1.2, and the tops of the side walls of the two lifting columns 3.1 are connected by the lifting cross beam 3.2. On both sides of the material table 3.9 between the two groups of lifting brackets, they are respectively connected to the bottom ends of the lifting screws 3.7 at the front ends of the lifting columns 3.1 (i.e., the side opposite to the two groups of lifting brackets) through the table lifting seats 3.8. The top ends of the lifting screws 3.7 pass through the tops of the lifting columns 3.1 and are placed inside the lifting screw bases 3.5. Both ends of the lifting transmission shaft 3.4 are placed inside the lifting screw bases 3.5 of the lifting brackets and are in worm and gear transmission connection with the lifting screws 3.7. The lifting drive reduction motor 3.6 is installed in the middle of the lifting cross beam 3.2, and the output end of the lifting drive reduction motor 3.6 is connected to the middle of the lifting transmission shaft 3.4 to provide lifting power. The material 3.3 is placed on the material table 3.9. The lifting drive reduction motor 3.6 drives the lifting screw 3.7 to lift through the lifting transmission shaft 3.4, and then the lifting screw 3.7 supports the material 3.3 to lift through the material table 3.9. A plurality of jacks are arranged in sequence on both sides of the material table 3.9 towards the center direction. The two baffles 3.10 are respectively inserted into the corresponding jacks according to the width of the material 3.3, thereby preventing operation failures such as wire breakage and wire jamming caused by the peeling off of the edge skin of the material 3.3.

[0047] The swing system 4 is as Figure 5 and Figure 6 shown and includes a swing base 4.1, a first support seat 4.2, an inner frame 4.3, a swing beam 4.4, a swing motor 4.5, a reducer 4.6, a swing transmission shaft 4.7, a second support seat 4.8, a crank 4.9, a linear slide rail 4.10, etc.

[0048] The inner frame 4.3 is of a frame structure. On both sides of the middle of the bottom of the inner frame 4.3, first support seats 4.2 are symmetrically installed. The first support seats 4.2 are placed on the swing base 4.1, and the center of the first support seat 4.2 is connected to the swing base 4.1 through a hinge shaft. The first support seat 4.2 can swing relative to the swing base 4.1 around the central hinge shaft, and thus the inner frame 4.3 can swing relative to the foundation embedded assembly 1 (i.e., the installation site). The swing base 4.1 is fixed on the outer frame 2 and is used to support the swing system 4 to ensure the stability of the swing system 4 during the swing movement.

[0049] The swing beam 4.4 is a beam for transmitting swing power and is composed of a fixed part and an extension part. The fixed part is installed on the top of one side of the inner frame 4.3 through a support frame, and the extension part extends to the outside of the inner frame 4.3. One or two linear slide rails 4.10 are fixed on the inner side of the extension part of the swing beam 4.4.

[0050] On the outer side of the end of the inner frame 4.3 where the swing beam 4.4 is installed, a swing motor 4.5 and a second support seat 4.8 are respectively installed on the top beam of the outer frame 2. The swing motor 4.5 is the swing power source and can adopt a precision servo motor. The output shaft of the swing motor 4.5 is connected to a speed reducer 4.6. The output shaft of the speed reducer 4.6 is connected to one end of a crank 4.9 through a swing transmission shaft 4.7. The other end of the crank 4.9 is rotatably connected to a slider on the linear slide rail 4.10, that is, the crank 4.9 can rotate relative to the slider. The crank 4.9 in this embodiment includes but is not limited to a long strip structure with arc ends at both ends. When the crank 4.9 rotates, the slider slides reciprocally along the linear slide rail 4.10. The second support seat 4.8 is sleeved on the swing transmission shaft 4.7 and plays a supporting role for the swing transmission shaft 4.7.

[0051] The wire cutting system 5 is installed on the inner frame 4.3. When the swing system 4 works, the swing motor 4.5 drives the crank 4.9 to rotate through the speed reducer 4.6 and the swing transmission shaft 4.7, drives the slider to move along the linear slide rail 4.10, and at the same time drives the first support seat 4.2 to swing relative to the swing base 4.1, so that the slider slides reciprocally along the linear slide rail 4.10. The linear slide rail 4.10 drives the entire inner frame 4.3 to swing back and forth through the swing beam 4.4, and thus the wire cutting system 5 swings together with the inner frame 4.3.

[0052] The wire cutting system 5 in this embodiment includes a wire routing adjustment mechanism, a wire pay-off and take-up mechanism, a tension mechanism, and a cutting roller, as Figure 7 shown. One end of the cutting wire 5.14 forms a wire mesh through the cutting roller for cutting the material 3.3. The other end of the cutting wire 5.14 sequentially passes through the wire routing adjustment mechanism, the tension mechanism, and the wire pay-off and take-up mechanism, and the cutting wire 5.14 is paid off and taken up through the wire pay-off and take-up mechanism.

[0053] Specifically, the wire cutting system 5 includes a wiring adjustment slider group 5.1, a wiring adjustment guide pulley 5.2, a wire arranging linear module 5.3, a wire arranging motor 5.4, a wire arranging deviation correction mechanism 5.5, a wire arranging guide pulley 5.6, a wire winding and unwinding wheel 5.7, a wire winding and unwinding seat 5.8, a wire winding and unwinding motor 5.9, a tension motor 5.10, a tension guide pulley 5.11, a tension torsion arm 5.12, a tension motor seat 5.13, a cutting wire 5.14, a roller 5.15, a roller driven shaft box 5.16, a roller drive shaft box 5.17, and a roller motor 5.18.

[0054] On the upper sides of the two outer ends of the inner frame 4.3 opposite to the swing motor 4.5, a wiring adjustment slider group 5.1 and a tension motor seat 5.13 are respectively installed. The wiring adjustment guide pulley 5.2 is installed on the wiring adjustment slider group 5.1 to form a wiring adjustment mechanism for the cutting wire 5.14. By adjusting the position of the wiring adjustment guide pulley 5.2, the cutting position of the cutting wire 5.14 to the outermost side of the material 3.3 can be adjusted to prevent empty cutting, and it is also convenient for the adjustment and arrangement of the baffle 3.10.

[0055] The tension motor 5.10 is installed on the tension motor seat 5.13. The output shaft of the tension motor 5.10 is connected to the tension guide pulley 5.11 through the tension torsion arm 5.12 to form a tension mechanism. The tension mechanism monitors the tension of the cutting wire 5.14 through a tension sensor and feeds it back to the tension motor 5.10. The tension of the cutting wire 5.14 is adjusted by driving the tension guide pulley 5.11 to move by the tension motor 5.10, so that the cutting wire 5.14 maintains a predetermined tension. At the same time, the tension guide pulley 5.11 also controls the turning of the cutting wire 5.14. And the top height of the tension guide pulley 5.11 is the same as the bottom height of the wiring adjustment guide pulley 5.2, so that the cutting wire 5.14 between the wiring adjustment guide pulley 5.2 and the tension guide pulley 5.11 is in a horizontal state.

[0056] Below the wiring adjustment mechanism, the wire arranging linear module 5.3 is installed on the inner frame 4.3. The wire arranging deviation correction mechanism 5.5 and the wire arranging guide pulley 5.6 are respectively installed on the wire arranging linear module 5.3. The wire arranging motor 5.4 is installed on the inner frame 4.3 at one end of the wire arranging linear module 5.3. The wire arranging motor 5.4 drives the wire arranging deviation correction mechanism 5.5 and the wire arranging guide pulley 5.6 to move linearly along the wire arranging linear module 5.3. The top height of the wire arranging guide pulley 5.6 is the same as the bottom height of the tension guide pulley 5.11, so that the cutting wire 5.14 between the tension guide pulley 5.11 and the wire arranging guide pulley 5.6 is in a horizontal state. The front end of the wire arranging deviation correction mechanism 5.5 has two guide pulleys, and the cutting wire 5.14 passes through between the two guide pulleys, which is used to guide the inclined cutting wire 5.14 to extend linearly downward to the wire winding and unwinding wheel 5.7, so as to realize the wire arranging function of neatly winding and unwinding the cutting wire 5.14.

[0057] Below the linear module 5.3 of the wire arrangement, the wire pay-off and take-up seat 5.8 is installed on the inner frame 4.3. The wire pay-off and take-up motor 5.9 is installed on the inner side of the wire pay-off and take-up seat 5.8 close to the inner side. The output shaft of the wire pay-off and take-up motor 5.9 passes through the wire pay-off and take-up seat 5.8 and is connected to the wire pay-off and take-up wheel 5.7. The wire pay-off and take-up wheel 5.7 is located below the wire arrangement deviation rectifying mechanism 5.5. The cutting wire 5.14 is paid off and taken up by driving the wire pay-off and take-up wheel 5.7 to rotate by the wire pay-off and take-up motor 5.9. In this embodiment, the linear velocity friction of the cutting wire 5.14 against the material 3.3 during the pay-off and take-up process is utilized to achieve the cutting function.

[0058] Rollers 5.15 are respectively arranged at the upper and lower left and right ends inside the inner frame 4.3, and the rollers 5.15 are parallel to the swing transmission shaft 4.7. Both ends of the rollers 5.15 are respectively installed on the inner frame 4.3 through roller driven shaft boxes 5.16 and roller drive shaft boxes 5.17 to provide support for the rollers 5.15 with large length dimensions and ensure the strength, rigidity and accuracy of the rollers 5.15. The roller motor 5.18 is installed on the roller drive shaft box 5.17. The output shaft of the roller motor 5.18 passes through the roller drive shaft box 5.17 and is connected to the roller 5.15. The roller motor 5.18 provides torque for the roller 5.15. The roller 5.15 in this embodiment is in a cylindrical shape, and V-shaped wire grooves are evenly distributed on the surface of the cylinder at intervals required by the cutting piece thickness of the material 3.3. On the four rollers 5.15, it is ensured that the cutting wire 5.14 on the cutting side (i.e., the top of the upper roller 5.15 and the bottom of the lower roller 5.15) is parallel to the material table 3.9, and the cutting wire 5.14 on the other sides is helically wound around the roller 5.15 to realize the wire net arrangement of the cutting wire 5.14. In this embodiment, the friction between the cutting wire 5.14 and the roller 5.15 is utilized to cooperate with the wire pay-off and take-up mechanism to promote the pay-off and take-up operation of the cutting wire 5.14. The linear velocity friction of the cutting wire 5.14 against the material 3.3 during the pay-off and take-up process is utilized to achieve the cutting function, and the cutting amplitude and cutting force are increased through the swing action during the cutting process, which is beneficial to improving the cutting efficiency.

As Figure 8As shown, the spraying assembly includes a water pump 8.1, a water delivery pipeline 8.2, a water tank 8.3, a connecting pipe 8.4, a water collecting pipe 8.5, and a water outlet pipeline 8.6. The two water tanks 8.3 arranged at intervals are respectively installed on the top of the outer frame 2 through brackets. The water pump 8.1 is installed at the lower part of the outer frame 2, and the outlet of the water pump 8.1 is connected to the two water tanks 8.3 through the water delivery pipeline 8.2 to deliver water to the water inlet tank 8.3. One end of the water tank 8.3 is respectively connected to the water collecting pipe 8.5 through a plurality of connecting pipes 8.4. The water collecting pipe 8.5 is sequentially connected to the two water outlet pipelines 8.6 through pipelines.

[0061] Embodiment 2

[0062] This embodiment describes a wire cutting machine, which is different from Embodiment 1 in that the structure of the swing system 4 is different. The swing system 4 is placed inside the outer frame 2, as Figure 9 shown, the swing system 4 includes a swing beam 4.4, a swing motor 4.5, a speed reducer 4.6, a swing transmission shaft 4.7, a crank 4.9, a linear slide rail 4.10, a swing fixed base 4.11, a swing shaft end plate 4.12, a swing hinge seat 4.13, a swing lower cross beam 4.14, a swing hinge bearing 4.15, a swing hinge shaft 4.16, a swing column 4.17, a swing middle cross beam 4.18, a swing guide friction plate 4.19, a crank rotating shaft seat 4.20, and a coupling 4.21.

[0063] Two swing fixed bases 4.11 are fixedly installed on the embedded installation plate 1.2 of the equipment in parallel at intervals, and play the role of bearing and supporting the swing system 4. A vertical plate is provided upward at the center above the swing fixed base 4.11. The swing hinge seat 4.13 is a U-shaped structure with the opening facing downward. The swing hinge seat 4.13 is buckled on the vertical plate, and the centers of the two are connected by a swing hinge shaft 4.16. Both ends of the swing hinge shaft 4.16 are respectively installed on the central side of the swing hinge seat 4.13 through swing shaft end plates 4.12, and a swing hinge bearing 4.15 is sleeved on the swing hinge shaft 4.16. Thus, the swing fixed base 4.11, the swing shaft end plate 4.12, the swing hinge seat 4.13, the swing hinge bearing 4.15 and the swing hinge shaft 4.16 form a hinge mechanism, enabling the swing hinge seat 4.13 to swing and rotate relative to the center of the swing fixed base 4.11, and the swing hinge bearing 4.15 can reduce the swing friction force.

[0064] The swing hinge seat 4.13, the swing lower cross beam 4.14, the swing upright columns 4.17, the swing middle cross beams 4.18 and the swing beam 4.4 form a swing frame. Two swing upright columns 4.17 are symmetrically installed on the swing hinge seat 4.13. At the lower part of the swing upright columns 4.17, both ends of the swing lower cross beam 4.14 are respectively fixed on the side walls of the swing upright columns 4.17. Multiple swing middle cross beams 4.18 are installed at intervals on the upper part of the swing upright columns 4.17. The fixed part of the swing beam 4.4 is installed at the top of the swing upright columns 4.17, and the extending part of the swing beam 4.4 extends to the outside of the swing upright columns 4.17.

[0065] The swing motor 4.5 is fixed on the outer frame 2 in the middle of the extending parts of the two swing beams 4.4. The output shaft of the swing motor 4.5 is connected to the reducer 4.6, and the output end of the reducer 4.6 is connected to the center of the swing transmission shaft 4.7. Both ends of the swing transmission shaft 4.7 are respectively connected to the crank 4.9 through couplings 4.21, and crank rotation shaft seats 4.20 are symmetrically arranged on both sides of the reducer 4.6. The crank rotation shaft seats 4.20 are fixed on the outer frame 2, and the swing transmission shaft 4.7 passes through the crank rotation shaft seats 4.20, and the crank rotation shaft seats 4.20 provide rotational support for the swing transmission shaft 4.7. The crank 4.9 is connected to the linear slide rail 4.10 on the inner side of the end of the extending part of the swing beam 4.4 through a slider, and the crank 4.9 and the linear slide rail 4.10 form a crank-slider mechanism.

[0066] The wire cutting system 5 is installed inside the swing frame. When the swing motor 4.5 drives the crank 4.9 to rotate through the swing transmission shaft 4.7, the slider reciprocates along the linear slide rail 4.10. The crank 4.9 converts the received rotational power into linear power to drive the swing beam 4.4 to generate a linear motion, and the swing beam 4.4 drives the swing frame to swing back and forth, thereby driving the wire cutting system 5 to swing.

[0067] Swing guide friction plates 4.19 are respectively installed at both outer ends of the two swing beams 4.4. The swing guide friction plates 4.19 are connected to the guide limit plates installed on the inner side of the outer frame 2. When the swing system 4 swings, the swing guide friction plates 4.19 cooperate with the guide limit plates to achieve the lateral guide and limit function when the swing system 4 operates.

[0068] The swing system 4 of this embodiment is a non-closed structure, which is beneficial to the loading and unloading of the extra-large material 3.3.

[0069] Embodiment Three

The difference from the above two embodiments is that a crane 9 (see Figure 2 ) is installed at the central axis of the top of the outer frame 2, which is used for hoisting materials 3.3, rollers 5.15, etc., so as to realize the loading and unloading of the material 3.3 and the adjustment of the position of the roller 5.15 when cutting materials 3.3 of different specifications, solve the problem that the thickness dimension of the processed sheets is single and the replacement of dimensions is very cumbersome, and is beneficial to expanding the applicability of the wire cutting machine.

[0071] Although the principle of the present invention has been described in detail above in combination with the preferred embodiments of the present invention, those skilled in the art should understand that the above embodiments are only explanations of the schematic implementation modes of the present invention, and do not limit the scope of the present invention. The details in the embodiments do not constitute a limitation on the scope of the present invention. Without departing from the spirit and scope of the present invention, any obvious changes such as equivalent transformation and simple replacement based on the technical solution of the present invention all fall within the protection scope of the present invention.
