[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0027] Examples, such as Figure 1-7As shown, a metal plate cutting device includes a conveying table 1, on which a plurality of bottom supporting smooth ribs 2 extending front and back and spaced apart left and right are installed and connected for supporting and conveying the metal plate j forward. The surface of at least the upper half of the bottom supporting smooth ribs 2 is smooth, and the smooth bottom supporting smooth ribs 2 are suitable for placing the metal plate j and conveying it forward. The cutting device of this embodiment is suitable for cutting of metal plates j with high requirements. For example, if high-quality and high-precision thick steel plates need to be processed, the equipment of this embodiment is very suitable. The originally processed steel plates need to be smooth and flat, and the cleanliness of the site needs to be high to reduce pollutants such as dust. Furthermore, the conveying platform 1 is provided with a conveying push frame that can push the metal plate forward and push downward against the bottom support smooth rib 2. The conveying push frame pushes the metal plate forward. Specifically, the front side of the conveying push frame is formed with a pushing portion for pushing the metal plate forward at the rear side and an anti-warping balance portion located above the pushing portion and used to limit the upper surface of the rear side edge of the metal plate, that is, the front side of the pushing portion pushes against the rear tail of the metal plate to move forward. Then, when cutting, there is a setting of the anti-warping balance portion, so that when the metal plate is sent to the predetermined position for cutting, the rear side will not be warped to cause poor cutting effect, overall deformation of the metal plate and other problems. A cutting tool d is arranged in front of the bottom support smooth rib 2. The cutting tool d can be a laser, a hydraulic gantry cutting knife or a circular saw blade, etc. If it is for the purpose of high cleanliness, it is appropriate to use the first two cutting tools.

[0028] Preferably, a propulsion and accommodation gap 20 is formed between two adjacent bottom support smooth ribs 2, that is, a left-right gap is formed between adjacent bottom support smooth ribs 2 and the gap extends forward and backward, and the propulsion portion includes a row of positioning propulsion comb teeth 310 that are spaced left and right and can extend into the propulsion and accommodation gap 20 and move forward and backward. The positioning propulsion comb teeth 310 extend up and down, and the comb teeth can be in the shape of round rods. On the one hand, the positioning propulsion comb teeth 310 perform a forward pushing operation at the rear side, and on the other hand, they also move forward and backward in the propulsion and accommodation gap 20, thereby limiting the left and right positions, so that the conveying push frame can move forward and backward better.

[0029] Preferably, the conveying and pushing frame is in a flat shape and includes a front connecting rod 41 extending left and right, a left oblique connecting rod 42 extending to the right rear fixed to the left end of the front connecting rod 41, a right oblique connecting rod 43 extending to the left rear fixed to the right end of the front connecting rod 41, and a rear connecting reinforcing plate 44 fixed between the rear ends of the left oblique connecting rod 42 and the rear ends of the right oblique connecting rod 43. The front connecting rod 41, the left oblique connecting rod 42, the right oblique connecting rod 43 and the rear connecting reinforcing plate 44 can all be made of steel parts, and the rear connecting reinforcing plate 44 can be a flat rectangular plate. Further, the front connecting rod 41, the left oblique connecting rod 42, the right oblique connecting rod 43 and the rear connecting reinforcing plate 44 surround and form an isosceles trapezoidal frame. Such a structure has better stability.

[0030] Preferably, a middle reinforcing connecting rod 45 extending forward and backward is fixed between the left and right middle parts of the rear side of the front connecting rod 41 and the left and right middle parts of the front side of the rear connecting reinforcing plate 44. The middle reinforcing connecting rod 45 can also be made of steel. A hydraulic lifting cylinder 440 extending upward and downward is fixed on the upper surface of the rear connecting reinforcing plate 44. The hydraulic lifting cylinder 440 is also connected to a horizontal moving device 441. The hydraulic lifting cylinder 440 can also be an electric lifting rod. The main purpose is to lift the rear connecting reinforcing plate 44 up and down to realize the lifting and lowering of the entire conveying and pushing frame. The hydraulic lifting cylinder 440 is suitable for a relatively large conveying and pushing frame, that is, the metal plate size is relatively large, and the hydraulic lifting will be more stable when the load is high. Further, the cylinder body of the hydraulic lifting cylinder 440 is close to the top and the piston rod lifting part is close to the bottom, and the piston rod lifting part and the middle front and rear parts of the middle reinforcing connecting rod 45 can be further fixedly connected with a diagonal rod 46 inclined to the horizontal plane, so that the conveying and pushing frame has better three-dimensionality and better structural strength and stability. The fixing of the above-mentioned rods and plates can be achieved by existing fixing methods such as welding or bolts. Since the conveying push frame needs to be able to move forward and backward, and preferably also move left and right, it can better adjust the horizontal position and push the metal plate forward and return. The hydraulic lifting cylinder 440 is required to be connected to a transverse moving device 441. The cylinder body of the hydraulic lifting cylinder 440 can be connected to the transverse moving device 441. The transverse moving device 441 can also be a combination of a hydraulic cylinder, or an electric moving device combination, or a screw moving device combination, or a mechanical arm. The main device can be a device that can complete the forward, backward, left and right movement. The moving part can be fixed to the cylinder body of the hydraulic lifting cylinder 440.

[0031] Preferably, the bottom supporting smooth rib 2 is a round rod-shaped steel pipe structure. The metal plate is supported by the steel pipe, which dissipates heat and ventilation, and is conducive to the evacuation of heat when cutting thick plates. In the case of this design with only steel pipes, further optimization can better cool the cutting process. In addition, the support of the steel pipe is also good. Of course, the material and size of this steel pipe must ensure that it is strong enough, otherwise it is easy to deform and it is not easy to use.

[0032] Furthermore, two adjacent bottom support smooth ribs 2 are connected at the front or rear side through a connecting pipe 22 to form a cooling pipeline that winds back and forth. For example, starting from the left side, the front ends of the first and second bottom support smooth ribs 2 are connected at the front side by a connecting pipe 22 that is connected to both, and the rear ends of the second and third bottom support smooth ribs 2 are connected at the rear side by a connecting pipe 22 that is connected to both, that is, the connecting pipe 22 is arranged in a front-to-back circulation. The material of the connecting pipe 22 is consistent with the bottom support smooth rib 2 and is preferably semicircular, so that the entire pipeline circulates back and forth in the left and right directions. This is to further optimize the cooling and heat dissipation structure, so that the metal plate can have good heat dissipation performance when supported by the bottom support smooth rib 2. Because the plate is thick, the cutting time is long, or in the case of laser cutting, the heat generated during the cutting process is very large, which will affect the shape and internal structure of the metal plate. In order to reduce these effects, timely and comprehensive cooling is required. The above scheme can achieve this very well. Furthermore, one of the leftmost bottom support smooth rib 2 and the rightmost bottom support smooth rib 2 is connected to the coolant inlet pipe 221, and the other is connected to the coolant outlet pipe 222. In this way, the entire cooling pipeline has the coolant in and out update, and can always maintain a cooling state. Of course, if it is in an uncut state, the coolant does not need to circulate. Of course, the other port of the coolant inlet pipe 221 and the other port of the coolant outlet pipe 222 are connected to a coolant supply and recovery system to form a closed-loop system. Of course, this coolant supply and recovery system can adopt the existing coolant circulation system, and the coolant can adopt conventional coolant.

[0033] Preferably, the anti-warping balancing part includes a baffle plate 321 extending left and right and installed on the front connecting rod 41, and a left limiting wheel 322 and a right limiting wheel 323 respectively installed and connected to the front connecting rod 41 and located on the left and right sides of the baffle plate 321. The left limiting wheel 322 and the right limiting wheel 323 can both move left and right. The baffle plate 321 can be made of steel plate and fixed on the front upper side of the front connecting rod 41. The left limiting wheel 322 and the right limiting wheel 323 can be respectively installed and connected to the two end parts of the front connecting rod 41. In addition, the left limiting wheel 322 and the right limiting wheel 323 should be able to move left and right, so that they can better perform flexible limiting, complete the close and precise left and right clamping limiting, and open left and right for initial limiting. For example, the initial interval between the left limiting wheel 322 and the right limiting wheel 323 is larger than the left and right width dimensions of the metal plate to be cut. The metal plate is usually made of rectangular plate and sent to the conveying platform by a vacuum suction cup transplanting equipment. At this time, the position is not accurate enough. The conveying push frame pushes the metal plate forward by the side at the rear side of the metal plate, and the left limiting wheel 322 and the right limiting wheel 323 move left and right and retract. At the same time, the hydraulic lifting cylinder 440 moves left and right through the lateral moving device, so that the metal plate is in the middle of the left limiting wheel 322 and the right limiting wheel 323, that is, the left limiting wheel 322 and the right limiting wheel 323 maintain a telescopic distance that is mirror-symmetrical on the left and right. Here, it can be set that the left end of the front connecting rod 41 is installed and connected to a left-right moving device on the left, such as a left-right telescopic cylinder, and the left limiting wheel 322 is installed and connected to the telescopic rod of the left and right telescopic cylinders. Similarly, the left end of the front connecting rod 41 is installed and connected to a right-right telescopic cylinder and the telescopic rod of the left and right telescopic cylinder is installed and connected to the right limiting wheel 323. The installation structure of these two sets of limiting wheels and left and right telescopic cylinders is mirror-symmetrical about the left and right centers of the front connecting rod 41. At the time of final positioning, it is preferred that the rightward and leftward movement amounts of the two telescopic cylinders on the left and right are the same. Of course, the extension and retraction of these hydraulic cylinders can be automatically controlled by existing automatic control equipment, which will not be elaborated here.

[0034] Furthermore, the pushing and accommodating gap 20 is provided with a left limiting body 201 and a right limiting body 202 for respectively abutting and limiting the left and right sides of the positioning and promoting comb teeth 310. The gap of the pushing and accommodating gap 20 is slightly larger, mainly for the smooth advancement of the conveying and pushing frame, but when cutting, better positioning is required. As mentioned above, when the left limiting wheel 322 and the right limiting wheel 323 are tightened and are in a symmetrical position, the left and right positions of the entire body including the metal plate can be controlled by moving the left and right positions of the hydraulic lifting cylinder 440. The interval between the left limiting body 201 and the right limiting body 202 should be just enough for the positioning and promoting comb teeth 310 to move forward and be embedded. The left limiting body 201 and the right limiting body 202 are arranged in a front position, and when the final cutting and positioning is performed, the positioning and promoting comb teeth 310 are stuck between the left limiting body 201 and the right limiting body 202, so that accurate positioning can be better performed. Due to the arrangement of the left limiter 201 and the right limiter 202, if the position of the positioning and pushing comb teeth 310 is not aligned, the positioning and pushing comb teeth 310 will be aligned in front by the left limiter 201 or the right limiter 202, and it is necessary to fine-tune the left and right positions of the hydraulic lifting cylinder 440 so that the positioning and pushing comb teeth 310 can just pass through the gap between the left limiter 201 and the right limiter 202 and be in the corresponding gap between the left limiter 201 and the right limiter 202. The positioning and pushing comb teeth 310 can be embedded with a micro switch or an infrared sensor or a pressure sensor, which is used to detect the position of the front right limiter 202, so that the hydraulic lifting cylinder 440 can adjust the left and right positions to adjust the positioning and pushing comb teeth 310 and the position of the entire conveying and pushing frame. The left limiter 201 and the right limiter 202 can adopt structures such as rollers or universal balls.

[0035] Furthermore, pressure sensors are embedded in the left limiter 201 and the right limiter 202. The pressure sensors can be miniature wireless or wired sensors. The wired sensors can be wired below the conveyor table as long as they do not affect the movement and cutting of the metal plate. The pressure detection here is used to sense the left and right squeezing force when the positioning and pushing comb teeth 310 are between the left limiter 201 and the right limiter 202, because many cutting methods will drive the metal plate in the left and right directions. By detecting the pressure, the hydraulic lifting cylinder 440 can be reminded to generate a corresponding left and right movement trend to balance this force, so that when cutting, the metal plate is more evenly stressed on the left and right sides.

[0036] Further, a platform limiting groove 10 is formed on the upper surface of the platform of the conveying platform 1 for the bottom support smooth rib 2 and the connecting tube 22 to be embedded and positioned downward. The platform limiting groove 10 is mainly used for the bottom support smooth rib 2 and the connecting tube 22 to be embedded and limited by the lower half, so that the bottom support smooth rib 2 and the connecting tube 22 are convenient to be disassembled and assembled up and down, but in this way, there will be mobility in the up and down directions, so further installation and fixing are required, and further optimization: at least one of the front end of the bottom support smooth rib 2, the rear end of the bottom support smooth rib 2 or the connecting tube 22 is detachably connected to the platform, and a stopper b that can be fixedly connected to the platform by bolts or the like can be provided, and an arc-shaped limiting surface is formed on the stopper b that is horizontally against the bottom support smooth rib or the connecting tube 22 by the upper half, of course, the top of the stopper b cannot exceed the highest position of the bottom support smooth rib or the connecting tube 22, otherwise it will affect the movement of the metal plate, and of course, other methods can also be used to fix the bottom support smooth rib 2 and the connecting tube 22 in an existing manner to further install and position. In addition, the site needs to maintain a good degree of cleanliness. Some exhaust equipment can be used at the cutting position to remove some metal chips, which can also have a certain cooling effect. Since the bottom support smooth rib 2 is blocked by a metal plate, less debris enters and only needs to be cleaned regularly.

[0037] Through the design of the above-mentioned cutting equipment, the original large-sized metal plate is placed on the conveying table through the existing loading equipment, the conveying push frame pushes the metal plate forward and adjusts the left and right positions of itself and the metal plate, and finally, the positioning push comb 310 enters between the left limit body 201 and the right limit body 202 for positioning, and the upper and lower lengths of the positioning push comb 310 exceed the thickness of the metal plate and have extensions on the upper and lower sides of the bottom support smooth rib 2, and the upper and lower lengths of the upper side need to exceed the thickness of the metal plate, and finally the conveying push frame sinks and presses the metal plate through the anti-warping balance part to cut, and the cooling part works at the same time, so that a good cutting process can be achieved. In addition, since the metal plate may need to be cut many times, multiple limit points can be set, that is, multiple pairs of left limit bodies 201 and right limit bodies 202 with equal front and rear intervals are set in a push-through gap 20 to perform multiple same-size cutting of the metal plate. In addition, according to the needs of processing different metal plates and different sizes, the table plate and the bottom support smooth rib 2 and the connecting pipe 22 on the table plate can be replaced, so that the flexibility of use is better. In this way, the control, performance, efficiency, and quality of cutting are greatly improved.

[0038] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
