Description

Technical Field

[0001] The invention belongs to the technical field of metal plate cutting, and in particular relates to a metal plate cutting device and a use method thereof. Background Art

[0002] Metal sheet cutting equipment is a type of equipment used for cutting metal sheets. It is mainly used for cutting, punching, grooving and other processing of metal sheets. Common metal sheet cutting equipment mainly includes circular saw cutting equipment, CNC plasma cutting equipment and laser cutting equipment. Among them, circular saw cutting equipment is widely used due to its low cost and simple equipment structure.

[0003] Currently, the common circular saw type metal sheet cutting equipment is mainly composed of a cutting workbench, a driving component, a circular saw cutting blade and other accessories. In actual application, the metal sheet to be cut is placed on the cutting workbench, and the circular saw cutting blade is controlled to rotate by the driving component to realize the cutting process of the metal sheet.

[0004] In order to ensure the accuracy of cutting processing, the common circular saw-type metal sheet cutting equipment in the prior art mainly clamps and fixes the metal sheet to be cut by additionally equipping a clamping and positioning component. Although this method can improve the cutting processing accuracy of the metal sheet, in actual application, it is not possible to independently clamp and transport the cut products and waste materials according to processing needs, which not only makes the unloading process of the cut metal sheet cumbersome and complicated, but also the metal sheet will be scratched by the friction of the chips during the sliding unloading process, which makes the convenience and efficiency of cutting the metal sheet poor.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0014] In one or more embodiments of the present invention, the lifting and retracting assembly includes a pair of lifting cylinders. The extension and reset states of the cylinder piston rods are controlled by controlling the air intake state of the pair of lifting cylinders, thereby facilitating the regulation of the lifting state of the chassis. The pair of lifting cylinders are both slidably equipped with cylinder piston rods. The cylinder piston rods support and fix the chassis and perform lifting and moving operations. The chassis is fixedly equipped with a chassis at one end of the cylinder piston rod located outside the lifting cylinder. The chassis functions as an assembly limit for the mobile connecting frame, a pair of guide light rods, and the threaded rod.

[0015] In one or more embodiments of the present invention, a slide rail is fixedly mounted on the upper part of the base frame, and a pair of sliders are slidably mounted on the upper part of the slide rail. The cooperation between the slide rail and the slider plays the role of assembly limit and sliding guide for the mobile connection frame. A mobile connection frame is fixedly mounted on the upper part of the pair of sliders, and the mobile connection frame is fixedly connected to the bottom of the clamping positioning plate. The mobile connection frame plays the role of supporting, fixing and moving control for the clamping positioning plate.

[0016] In one or more embodiments of the present invention, a pair of guide light rods are fixedly mounted in the base frame, and the pair of movable connecting frames are both slidably matched with the guide light rods.

A threaded rod is arranged between the pair of guide light rods, and a pair of external threads with opposite rotation directions are provided on the outer side of the threaded rod, and the pair of movable connecting frames are both threadedly connected with the threaded rod. The mutual cooperation of the internal and external threads enables the pair of movable connecting frames to move in opposite directions with the rotation of the threaded rod, thereby facilitating the driving of a pair of clamping and positioning plates to clamp and fix the plate to be cut.

[0017] In one or more embodiments of the present invention, a driving pulley is fixedly mounted on the outer side of the threaded rod, and the driving pulley is arranged between a pair of mobile connecting frames. The threaded rod is driven to rotate by the rotation of the driving pulley, so as to facilitate driving a pair of clamping and positioning plates to clamp and fix the plate to be cut. A synchronous belt is sleeved on the outer side of the driving pulley. The synchronous belt serves to connect the driving pulley and the transmission pulley, so that the driving pulley can rotate synchronously with the rotation of the transmission pulley under the action of the synchronous belt. A transmission pulley is sleeved on the side of the synchronous belt away from the threaded rod. The transmission pulley serves to transmit the power of the driving motor. A driving motor is fixedly mounted below the base frame, and the output shaft of the driving motor is connected to the transmission pulley. The driving motor serves to provide power, and the transmission pulley is driven to rotate by controlling the operation of the driving motor. A dust cover is fixedly connected between the pair of mobile connecting frames. The dust cover serves to protect the threaded rod from dust.

[0018] In one or more embodiments of the present invention, a pair of cleaning handles are fixedly mounted above the filter plate.

The inner filter screen cartridge divides the dust filter cartridge into a dust filter chamber and an exhaust chamber, the air guide cover is connected to the exhaust chamber, and a pair of the dust filter cartridges and protective covers are connected with draft ducts, which are connected to the dust filter chamber. The draft duct serves to connect the dust filter cartridge and the purification guide duct, so as to collect and guide the exhaust gas and some chips generated during the cutting process of the cutting blade.

[0020] A method for using a metal sheet cutting device comprises the following steps:

[0021] S1. Before use, the surfaces of multiple groups of supporting conveying rollers can be cleaned by controlling the operation of the cleaning and positioning mechanism to prevent impurities from adhering to the surfaces of the supporting conveying rollers and causing scratches on the plates to be cut and affecting the positioning deviation. After the cleaning is completed, the cleaning and positioning mechanism is reset. Subsequently, the plates to be cut can be placed on the multiple groups of supporting conveying rollers, and the plates to be cut can be supported and rolled by the rotation of the multiple groups of supporting conveying rollers.

[0022] S2. When the plate to be cut moves to the bottom of the cutting disc, the driving motor can be controlled to drive the driving pulley to rotate, and the threaded rod can rotate under the cooperation of the driving pulley, the synchronous belt and the driving pulley. A pair of movable connecting frames can move in opposite directions with the rotation of the threaded rod under the action of the internal and external threads, so as to clamp the plate to be cut by driving a pair of clamping positioning plates to move, and the bottom surface of the plate to be cut can be supported by the supporting bottom plate;

[0023] S3. At the same time, the clamping and positioning plate can be lifted and controlled by controlling a pair of cylinder piston rods to extend, so as to support and clamp the metal sheet to be cut. Then, the metal sheet cutting process can be realized by rotating and moving the cutting disc. The sheet dropped during the cutting process can be supported and independently conveyed by multiple groups of supporting and conveying rollers, so as to realize the purpose of conveying the metal sheet and waste materials in steps.

[0024] S4. In addition, the adsorption purification liquid can be stored in the liquid collecting box. When the cutting disc cuts the metal sheet, the chips dropped by the cutting can be collected by the liquid collecting box, thus avoiding the adverse effects of the chips on the subsequent transportation and positioning of the metal sheet and waste;

[0025] S5. Furthermore, the air in the exhaust chamber can be continuously extracted and transported by controlling the operation of the exhaust fan, so that the exhaust gas and part of the chips generated by the cutting disc during the rotary cutting process can be transported to the filter chamber along the air duct under the action of the airflow, and the impurities contained in the airflow can be filtered by the inner filter cylinder;

[0026] S6. The filtered waste gas can be transported along the purification guide pipe to the induced draft pipe, and adsorbed and purified by the adsorption purification liquid. The gas after adsorption purification can be transported from bottom to top along the impurity collecting box. The waste gas and chips generated during the cutting process of the cutting disc can be further collected and processed by the continuous flow of airflow.

[0027] Compared with the prior art, the present invention can independently transport the metal sheets and waste generated during the cutting process by arranging a split clamping limit mechanism and a dust suppression and collection mechanism, thereby simplifying the process of unloading the metal sheets, greatly reducing the adverse effects of chips on the metal sheet cutting process, and significantly improving the convenience and efficiency of cutting and processing of metal sheets.

A pair of supporting bottom plates 204 are fixedly mounted on one side of the pair of clamping and positioning plates 203 close to the supporting and conveying rollers 202. The bottom of the metal sheet is supported and limited by the pair of supporting bottom plates 204, which is convenient for the subsequent lifting and limiting of the metal sheet.

[0053] like Figures 2 to 3 As shown, a lifting and retracting assembly is fixedly mounted below a pair of clamping and positioning plates 203. The lifting and retracting assembly includes a pair of lifting cylinders 205. The extension and reset states of the cylinder piston rods 206 are controlled by controlling the air intake states of the pair of lifting cylinders 205, thereby facilitating the regulation of the lifting state of the base frame 207.

[0071] like Figures 9 and 10 As shown, one side of the fixed bottom plate 308 located in the dust filter cylinder 305 is fixedly connected with an inner filter cylinder 309. The air transported by the induced draft pipe 310 is filtered through the inner filter cylinder 309.

[0072] Specifically, the inner filter cylinder 309 divides the dust filter cylinder 305 into a dust filter chamber and an exhaust chamber, and the air guide cover 306 is connected to the exhaust chamber.

[0073] like Figures 9 and 10 As shown, a pair of dust filter cylinders 305 and the protective cover 103 are both connected by an air duct 310, and the air duct 310 is connected to the dust filter chamber.

[0074] like Figures 6 to 8As shown, a pair of cleaning and positioning mechanisms 4 are fixedly assembled in the cutting machine box 1, and the cleaning and positioning mechanisms 4 are used to assist in cleaning the multiple groups of supporting and conveying rollers 202 and assist in supporting and positioning the metal plates.

[0075] like Figures 6 to 8 As shown, the cleaning positioning mechanism 4 includes a positioning bracket 401, and the positioning bracket 401 is slidably assembled in the cutting machine box 1. The positioning bracket 401 plays a role of assembling and limiting the cleaning brush 404 and the threaded connecting rod 405.

[0076] like Figures 6 to 8 As shown, a pair of cleaning cylinders 402 are fixedly installed in the cutting machine box 1, and piston rods 403 are slidably installed in the pair of cleaning cylinders 402. The piston rods 403 are fixedly connected to the bottom surface of the positioning bracket 401. By controlling the telescopic movement of the piston rods 403, the positioning bracket 401 is lifted and controlled, so that the contact state between the cleaning brush 404 and the supporting conveying roller 202 can be easily adjusted.

[0077] like Figures 6 to 8 As shown, a plurality of cleaning brushes 404 are fixedly mounted above the positioning bracket 401, and the plurality of cleaning brushes 404 are arranged directly below the plurality of supporting and conveying rollers 202. The impurities adhering to the surface of the supporting and conveying rollers 202 are cleaned by the mutual movement of the supporting and conveying rollers 202 and the cleaning brushes 404, thereby avoiding the adverse effects of the impurities on the subsequent supporting and positioning process of the metal sheet.

[0078] like Figures 6 to 8 As shown, a plurality of threaded connecting rods 405 are threadedly connected to the upper portion of the positioning bracket 401, and the plurality of threaded connecting rods 405 are arranged between the plurality of cleaning brushes 404. The threaded connecting rods 405 play a role in supporting, fixing and adjusting the position of the positioning block 406.

[0079] Preferably, the cleaning brush 404 and the threaded connecting rod 405 can be adaptively adjusted according to the actual size of the metal sheet and the cutting position.

[0080] like Figures 6 to 8 As shown, the top ends of the plurality of threaded connecting rods 405 are fixedly mounted with positioning blocks 406. The positioning blocks 406 are moved to assist in supporting and positioning the metal sheet.

[0081] Specifically, before use, the positioning bracket 401 can be lifted by controlling the piston rod 403 to extend, so that the multiple sets of cleaning brushes 404 are in contact with the lower end surface of the supporting conveying roller 202, and the surface of the supporting conveying roller 202 is cleaned by mutual contact. At the same time, the multiple threaded connecting rods 405 can be raised and lowered synchronously with the raising and lowering of the positioning bracket 401, and the metal sheet can be auxiliary supported and positioned by the multiple threaded connecting rods 405. After cleaning, the cleaning positioning mechanism 4 is reset, and then the sheet to be cut can be placed on the multiple sets of supporting conveying rollers 202, and the sheet to be cut can be supported and rolled by the rotation of the multiple sets of supporting conveying rollers 202.

[0082] When the plate to be cut moves to the bottom of the cutting blade 104, the driving pulley 215 can be driven to rotate by controlling the operation of the driving motor 216, and the threaded rod 212 can rotate under the cooperation of the driving pulley 213, the synchronous belt 214 and the driving pulley 215.
