Description

Technical Field

[0001] The utility model relates to the technical field of metal plate processing, in particular to a cutting device for metal plates. Background Art

[0002] Metal sheets are a very common raw material in the metal processing process. They can be made into various shapes through welding, assembly, bending, stamping, cutting and other processes. Long and thin sheets are usually transported in rolls, so that more metal sheets can be transported at one time. Shorter or thicker sheets are usually not coiled. Before processing, the sheets usually need to be pre-cut into specified sizes, especially the coiled sheets, to facilitate subsequent stamping, bending and other work. Cutting is mainly done by cutting the sheets with hydraulic shears or cutting the sheets into several narrow sheets with slitting machines.

[0003] During use, the existing hydraulic cutting device for metal sheets mainly uses a hydraulic cylinder to drive the cutting blade to apply force to the sheet to cut the sheet. The cut sheet will show four areas in its cross-section from high to low, namely, collapsed angle, shear surface, fracture surface and burrs, resulting in an uneven cross-section of the sheet, which not only affects subsequent processing, but also makes it easy for workers to be scratched by the cross-section when handling the sheet. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a cutting device for metal sheets to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cutting device for metal sheets, comprising a device main body, an edging assembly is arranged on the top of the device main body, and the edging assembly includes a support plate, a guide roller, a first bracket, a guide rail and a positioning plate, one side of the support plate is connected to a pressure plate through a spring sheet, two mounting wheels pass through the top of the first bracket, and a sandpaper belt is connected between the two mounting wheels and the guide roller, one end of each of the two mounting wheels is connected to a worm gear, a worm is connected to one side of the top of the first bracket, a linear motor is installed on the top of the guide rail, and the output end of the linear motor is connected to a push plate.

[0006] By adopting the above technical solution, the cut plates are pushed toward the roller by the cooperation of the linear motor and the push plate, and then the plates are automatically unloaded by the friction between the plates and the cooperation of the linear motor and the push plate. During the automatic unloading process, the cross section of the plate contacts the sandpaper belt. At this time, the plate and the sandpaper belt move relative to each other, so that the sandpaper belt grinds the cross section of the plate, thereby making its cross section smooth. At the same time, pressure is applied toward the plate by the spring piece and the pressure plate, so that the sandpaper belt is close to the cross section of the plate, thereby increasing the edge grinding effect. When the sandpaper belt is severely worn locally and difficult to grind, the worm is rotated, and the worm and the two worm wheels are engaged to drive the two mounting wheels to rotate synchronously. After one mounting wheel rotates, the unworn area of ​​the sandpaper belt is released, and after the other mounting wheel rotates, the worn area of ​​the sandpaper belt is reeled in, so that the edge grinding work can continue.

[0007] Furthermore, the pressing plate is slidably connected to the support plate, and the pressing plate abuts against the sandpaper belt.

[0008] By adopting the above technical solution, the sandpaper belt grinds the cross-section of the plate to make its cross-section flat. At the same time, the spring piece cooperates with the pressure plate to apply pressure toward the plate, so that the sandpaper belt is close to the cross-section of the plate, thereby increasing the edge grinding effect.

[0009] Furthermore, the worm is meshed with two worm wheels.

[0010] By adopting the above technical solution, the worm and the two worm wheels are meshed and driven to make the two mounting wheels rotate synchronously. When one mounting wheel rotates, the unworn area of ​​the sandpaper belt is released, and when the other mounting wheel rotates, the worn area of ​​the sandpaper belt is wound up, so as to continue the edging work.

[0011] Furthermore, the two ends of the sandpaper belt are detachably connected to the two mounting wheels via double-sided tape.

[0012] By adopting the above technical solution, the staff sticks one end of the new sandpaper belt to the front mounting wheel with double-sided tape, and then the staff rotates the worm to rotate the front mounting wheel to reel in the sandpaper belt. At this time, the staff leaves a section of the sandpaper belt without reeling it in, but passes the other end of the sandpaper belt through the guide roller, support plate and pressure plate to contact the rear mounting wheel, and then the staff sticks the other end of the sandpaper belt to the outside of the rear mounting wheel with double-sided tape.

[0013] Furthermore, the push plate is slidably connected to the device body and the positioning plate respectively.

[0014] By adopting the above technical solution, the cut plates are pushed toward the roller by the cooperation of the linear motor and the push plate, and then the plates are automatically unloaded by the friction between the plates and the cooperation of the linear motor and the push plate.

[0015] Furthermore, a grinding assembly is provided on the top of the device body, and the grinding assembly includes a second bracket, a first hydraulic cylinder is installed on the top of the second bracket, and the output end of the first hydraulic cylinder is connected to the slide through a piston rod, a second hydraulic cylinder is installed on the outer surface of the slide, and the output end of the second hydraulic cylinder is connected to a pressure block through a piston rod.

[0016] By adopting the above technical solution, after the second hydraulic cylinder is started, the output end drives the pressure block to move downward and resist the plate. After the first hydraulic cylinder is started, the output end drives the slide to reciprocate back and forth, so that the second hydraulic cylinder and the pressure block carry the plate to reciprocate back and forth, so as to cooperate with the edge grinding structure to grind the cross section of the plate flat.

[0017] Furthermore, the slide is in an I-shape, and the slide is slidably connected to the second bracket.

[0018] By adopting the above technical solution, the slide can play a guiding role to prevent the second hydraulic cylinder from lateral deviation. At the same time, the I-shaped slide can distribute the pressure to the top of the second bracket, avoiding all pressure being borne by the piston rod on the first hydraulic cylinder.

[0019] Furthermore, a gantry is connected to one side of the top of the device body, and a hydraulic shear is installed on the top of the gantry, and a roller passes through the top of the inside of the device body.

[0020] By adopting the above technical solution, the operator pushes the metal sheet to be cut to the top side of the device body and passes it through the bottom of the gantry. Then the operator starts the hydraulic shear, which cuts the sheet.

[0021] Furthermore, the back of the support plate is inclined toward a side away from the drum.

[0022] By adopting the above technical solution, the back of the support plate is tilted to one side so that the plate can better contact with the sandpaper belt, avoiding slight deviation of the plate and collision with the guide roller during the pushing process of the push plate.

[0023] Furthermore, a plurality of rollers are provided, and the plurality of rollers are distributed at equal intervals.

[0024] By adopting the above technical solution, the arrangement of multiple rollers avoids excessive friction between the plate and the device body during the unloading process, thereby reducing the resistance when unloading the plate.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The utility model sets an edge grinding component, and pushes the cut sheet to the roller through the cooperation of the linear motor and the push plate, and then automatically unloads the sheet through the friction between the sheets and the cooperation of the linear motor and the push plate. During the automatic unloading process, the cross section of the sheet contacts the sandpaper belt, and the sheet and the sandpaper belt move relative to each other, so that the sandpaper belt grinds the cross section of the sheet, thereby making its cross section flat. At the same time, the spring piece cooperates with the pressure plate to apply pressure in the direction of the sheet, so that the sandpaper belt is close to the cross section of the sheet, thereby increasing the edge grinding effect. When the sandpaper belt is severely worn locally and difficult to be edged, the worm is rotated, and the worm and the two worm wheels are meshed to drive the two mounting wheels to rotate synchronously. After one mounting wheel rotates, the unworn area of ​​the sandpaper belt is released, and after the other mounting wheel rotates, the worn area of ​​the sandpaper belt is reeled in, so as to continue the edge grinding work. It can automatically unload the sheet, and in the process of automatic unloading, the collapsed angles and burrs are removed and the shear surface and fracture surface are polished flat.

[0027] 2. The utility model arranges the grinding assembly and the edging assembly. After the second hydraulic cylinder is started, the output end drives the pressure block to move downward to resist the plate. After the first hydraulic cylinder is started, the output end drives the slide to reciprocate back and forth, so that the second hydraulic cylinder and the pressure block carry the plate to reciprocate back and forth, so as to cooperate with the edging structure to grind the cross section of the plate to be smooth, thereby avoiding the plate surface being uneven due to a short grinding time.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The following describes an embodiment of the present invention based on its overall structure.

[0035] Example 1:

[0036] A cutting device for metal sheets, such as Figure 1 、 Figure 3 and Figure 4 As shown, it includes a device body 1, and an edging assembly 5 is provided on the top of the device body 1.

[0037] Specifically, the edge grinding assembly 5 includes a support plate 501, a guide roller 504, a first bracket 506, a guide rail 510 and a positioning plate 513 respectively connected to the other side of the top of the device body 1. The back of the support plate 501 is inclined toward the side away from the roller 4, so that the cross section of the plate can be easily fitted with the sandpaper belt 505 after it moves; a pressure plate 503 is connected to one side of the support plate 501 through a spring piece 502, and the pressure plate 503 is slidably connected to the support plate 501. The pressure plate 503 abuts against the sandpaper belt 505, and the spring piece 502 cooperates with the pressure plate 503 to apply pressure in the direction of the plate, so that the sandpaper belt 505 is close to the cross section of the plate, thereby increasing the edge grinding effect; there are two mounting wheels 509 running through the top of the first bracket 506, and the two mounting wheels 509 and the guide roller A sandpaper belt 505 is connected between 504, and the two ends of the sandpaper belt 505 are detachably connected to the two mounting wheels 509 by double-sided tape. One end of the two mounting wheels 509 is connected to a worm gear 507. A worm 508 is connected to one side of the top of the first bracket 506. The worm 508 is engaged with the two worm gears 507. When the worm 508 is rotated, the worm 508 is engaged with the two worm gears 507 to transmit the two mounting wheels 509 to rotate synchronously; a linear motor 511 is installed on the top of the guide rail 510, and a push plate 512 is connected to the output end of the linear motor 511. The push plate 512 is slidably connected to the device body 1 and the positioning plate 513 respectively, and the cut plate is pushed toward the roller 4 through the cooperation of the linear motor 511 and the push plate 512.

[0038] See Figure 1 In the above embodiment, a gantry 2 is connected to one side of the top of the device body 1, and a hydraulic shear 3 is installed on the top of the gantry 2. After the hydraulic shear 3 is started, the plate is cut and severed; a roller 4 is passed through the top of the device body 1, and a plurality of rollers 4 are provided, and the plurality of rollers 4 are evenly distributed to reduce the resistance when the plate is unloading.

[0039] Example 2:

[0040] On the basis of the above-mentioned embodiment 1, although the edge grinding component 5 is provided to automatically cut the material, and the collapsed angles and burrs are removed and the shear surface and the fracture surface are polished smooth during the automatic cutting process; but the short cutting distance leads to a short polishing time, and the phenomenon of not polishing smooth may occur. If the cutting distance is increased, the floor space of the equipment will increase; now by providing the polishing component 6, it can be avoided that the plate surface is still uneven due to the short polishing time.

[0041] See Figure 1 and Figure 2 In the above embodiment, a grinding assembly 6 is provided on the top of the device body 1.

[0042] Specifically, the grinding assembly 6 includes a second bracket 601 connected to the other side of the top of the device body 1, and a first hydraulic cylinder 602 is installed on the top of the second bracket 601. The output end of the first hydraulic cylinder 602 is connected to the slide 603 through a piston rod. The slide 603 is in the shape of an "I". The slide 603 is slidably connected to the second bracket 601, so that the second hydraulic cylinder 604 and the pressure block 605 carry the plate back and forth to cooperate with the edging assembly 5 to grind the cross-section of the plate flat; a second hydraulic cylinder 604 is installed on the outer surface of the slide 603, and the output end of the second hydraulic cylinder 604 is connected to the pressure block 605 through a piston rod. After the second hydraulic cylinder 604 is started, the output end drives the pressure block 605 to move downward and resist the plate.

[0043] The implementation principle of the present utility model is as follows: first, the staff pushes the metal sheet to be cut to one side of the top of the device body 1 and passes through the bottom of the gantry 2, and then the staff starts the hydraulic shear 3. After the hydraulic shear 3 is started, the sheet is cut and cut. Then the staff continues to push the metal sheet to be cut and starts the linear motor 511. Then, the metal sheet to be cut presses against the sheet to be cut, so that the sheet to be cut moves to the right and abuts against the positioning plate 513. The positioning plate 513 prevents the sheet from colliding with the guide roller 504 when the push plate 512 pushes the sheet. At this time, the linear motor 511 and the push plate 512 cooperate to push the cut sheet to the roller 4. Then, the sheet is automatically unloaded through the abutment between the sheets and the push of the linear motor 511 and the push plate 512.

[0044] During the automatic unloading process, the cross section of the plate contacts the sandpaper belt 505. At this time, the plate and the sandpaper belt 505 move relative to each other, causing the sandpaper belt 505 to grind the cross section of the plate, thereby making its cross section flat. At the same time, the spring piece 502 cooperates with the pressure plate 503 to apply pressure toward the plate, so that the sandpaper belt 505 is tightly attached to the cross section of the plate, thereby improving the edge grinding effect.

[0045] When a plate is pushed to the bottom of the second bracket 601, the staff starts the first hydraulic cylinder 602 and the second hydraulic cylinder 604. After the second hydraulic cylinder 604 is started, the output end drives the pressure block 605 to move down and against the plate. After the first hydraulic cylinder 602 is started, the output end drives the slide 603 to slide forward first to avoid the plate from colliding with the plate behind when it moves backward. Then, the first hydraulic cylinder 602 drives the slide 603 to move backward and reciprocate back and forth, so that the second hydraulic cylinder 604 and the pressure block 605 carry the plate to reciprocate back and forth, so as to cooperate with the edge grinding assembly 5 to grind the cross section of the plate flat. After grinding, the staff closes the first hydraulic cylinder 602 and the second hydraulic cylinder 604 to reset the grinding assembly 6, prepare to grind the next plate and avoid affecting the unloading of the polished plate;

[0046] When the sandpaper belt 505 is severely worn and difficult to grind, the worker rotates the worm 508. At this time, the worm 508 engages with the two worm wheels 507 to drive the two mounting wheels 509 to rotate synchronously. After the front mounting wheel 509 rotates, the unworn area of ​​the sandpaper belt 505 is released, and after the rear mounting wheel 509 rotates, the worn area of ​​the sandpaper belt 505 is reeled in, so that the grinding work can continue.

[0047] When the sandpaper belt 505 is exhausted, the staff removes one end of the sandpaper belt 505 from the front mounting wheel 509, and then the staff reverses the worm 508 to rotate the rear mounting wheel 509 to release the sandpaper belt 505. After all the sandpaper belt 505 is released, the staff removes the other end of the sandpaper belt 505 from the rear mounting wheel 509, and then the staff sticks one end of the new sandpaper belt 505 to the front mounting wheel 509 with double-sided tape, and then the staff rotates the worm 508 to rotate the front mounting wheel 509 to release the sandpaper belt 505. 5 Rewinding, at this time the staff leaves a section of the sandpaper belt 505 unreeled, and passes the other end of the sandpaper belt 505 through the guide roller 504, the support plate 501 and the pressure plate 503 to contact the rear mounting wheel 509. Then the staff sticks the other end of the sandpaper belt 505 to the outside of the rear mounting wheel 509 with double-sided tape. It should be noted that the sandpaper belt 505 can be installed on either the front mounting wheel 509 or the rear mounting wheel 509 first. This technical solution only records one of them in the article. The principles are similar, so they are not fully recorded in the article.
