Description

Automatic profiling equipment for metal products

Technical Field

The invention belongs to the technical field of metal plate processing, in particular to an automatic profiling device for metal products.

Background Art

Metal profiling is a process of applying external force to metal sheets through specific techniques and equipment to cause them to undergo plastic deformation, thereby obtaining metal products of specific shapes, specifications and performances. Among them, metal tiles are made of aluminum-zinc-coated steel sheets.

A patent application with publication number CN217514612U discloses a multi-specification metal packaging press-forming equipment, including a workbench, a first base is provided at the upper end of the workbench, a first slide groove is provided in the middle of the vertical wall of the first base, a first cylinder is fixedly connected to the bottom end of the first slide groove, and the output end of the first cylinder is fixedly connected to the first slider, the first base and the second base are provided at the upper end of the workbench, a press-forming mechanism is provided above the first base, and a press-forming mechanism is provided on the side of the second base. The press-forming mechanism provides power through the cylinder to extrude the metal to be pressed, and the extrusion above and on the side of the metal to be pressed is performed simultaneously, which shortens the pressing time of a single metal and improves the working efficiency of the equipment.

There are still some problems in the actual application of the above scheme. Some metal products, such as metal tiles, need to be cut to size according to the process requirements before profiling. However, if the cutting work is carried out separately from the profiling work, the profiling efficiency will be greatly affected. In order to solve this problem, when the metal tiles are profiling, the raw materials of the profiling metal tiles will be transported to the lower end of the profiling mechanism through a conveyor belt, and cutting will be achieved during the profiling process, so that the cutting and profiling are integrated. However, if cutting is performed during the profiling process, the distance between the cut metal tiles and the metal tiles before cutting will be too close, which will not only bring difficulties to the operator and increase the operating risks, but also make it difficult to effectively dissipate the heat during the profiling process, ultimately affecting the profiling effect.

To this end, the present invention provides an automatic profiling device for metal products.

DETAILED DESCRIPTION

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

Embodiment 1

As shown in Figures 1 to 10, an automatic profiling device for metal products according to an embodiment of the present invention comprises a fixed frame 1, the fixed frame 1 comprises a profiling die 11, a profiling structure 2 is provided at the upper end of the fixed frame 1, and a conveying structure 3 is provided on one side of the fixed frame 1; the profiling structure 2 comprises: a cylinder 23, the cylinder 23 is provided at the upper end of the fixed frame 1; a connecting block 27, the connecting block 27 is provided at the lower end of the cylinder 23; a profiling plate 21, the profiling plate 21 is provided at the lower end of the connecting block 27, and the profiling plate 21 is used in conjunction with the profiling die 11 for preparing metal products. The material is a tile 5; a sliding plate 26, which is arranged at both ends of the connecting block 27, and the sliding plate 26 slides on the surface of the fixed frame 1; a cutting frame 25, which is arranged on one side of the fixed frame 1; a cutting knife 28, which is slidably connected to the inside of the cutting frame 25; the conveying structure 3 includes: an upper conveying roller 303, which is arranged at the rear of the fixed frame 1; a connecting roller 307, which is arranged at one end of the upper conveying roller 303; and a connecting track 304, which is sleeved on the surface of the connecting roller 307.

Specifically, in the automatic profiling equipment for metal products of the scheme, when in use, the raw material galvanized steel sheet used to prepare the metal tile 5 is first cut according to the demand, and then the cut galvanized steel sheet is placed on the surface of the profiling mold 11, and the cylinder 23 is started at this time, and the cylinder 23 will move downward with the connecting block 27, and the sliding plates 26 at both ends of the connecting block 27 and the corrugated plate 21 at the lower end of the connecting block 27 will move together, and finally the corrugated plate 21 will contact with the galvanized steel sheet, and as the corrugated plate 21 continues to move downward, appropriate pressure will be applied to the galvanized steel sheet, and when the applied pressure exceeds its yield point, the galvanized steel sheet will begin to plastically deform. , and the galvanized steel sheet will undergo plastic deformation under the constraints of the corrugated plate 21 and the corrugation mold 11, thereby obtaining the desired tile shape, and finally undergoing processes such as spraying and drying to make the metal tile 5. However, before corrugation, the galvanized steel sheet needs to be cut to size as required. If so, the cutting work will be separated from the corrugation work, affecting the preparation efficiency. In order to solve this problem, a conveyor belt and a cutting knife 28 will be set at one end of the corrugation equipment. By simply placing the galvanized steel sheet on the conveyor belt, the galvanized steel sheet can be driven to move toward the direction of the corrugation equipment, and the galvanized steel sheet can be cut by the cutting knife 28 during the movement, thereby achieving Automatic cutting, but this method will make the distance between the cut galvanized steel sheet and the uncut galvanized steel sheet too close. Since heat will be generated during the profiling process, if the two galvanized steel sheets are too close, the heat between them will be difficult to dissipate effectively, which will not only cause heat accumulation and affect the profiling effect, but also bring difficulties to the operator and increase the risk of operation. For this reason, a conveying structure 3 is set up. When performing the profiling work, it is only necessary to place the galvanized steel sheet on the surface of the upper conveying roller 303. At this time, the connecting crawler 304 is started, and the connecting crawler 304 will drive the connecting roller 307 to rotate together, and finally the galvanized steel sheet on the surface of the upper conveying roller 303 is The plate moves toward the profiling die 11. When a part of the galvanized steel plate moves onto the profiling die 11 and the size is determined, the cutting frame 25 is started, and the cutting frame 25 will drive the cutting knife 28 to move downward, and finally the galvanized steel plate is cut. After the cutting is completed, the connecting track 304 is started again, and the connecting track 304 will be reversed, so that the uncut galvanized steel plate moves away from the profiling die 11, so that there is a gap between the cut galvanized steel plate and the uncut galvanized steel plate, thereby avoiding the distance between the two being too close, resulting in the heat in the profiling process being difficult to effectively dissipate, affecting the profiling effect.

As shown in FIGS. 1 to 8 , the profiled structure 2 further includes: a connecting piece 22, the connecting piece 22 is fixedly connected to the upper surface of the profiled plate 21, and the rod above the connecting piece 22 slides on the inner wall of the fixed frame 1; the conveying structure 3 further includes: a conveying frame 301, the conveying frame 301 is arranged on one side of the fixed frame 1, and the upper conveying roller 303 is rotatably connected to the inside of the conveying frame 301; a rack 309, the rack 309 is arranged on one side of the cutting knife 28; a first gear 305, one end of the connection track 304 is sleeved with the first gear 305;

The second gear 306 is rotatably connected to one end of the first gear 305, and the second gear 306 is meshed with the rack 309; the transfer gear 308 is rotatably connected to the surface of the conveying frame 301, and the transfer gear 308 is meshed with the first gear 305, and the transfer gear 308 is meshed with the second gear 306.

Specifically, when the cutting knife 28 moves downward to cut the galvanized steel sheet, the rack 309 located on one side of the cutting knife 28 will also move downward. The rack 309 will mesh with the second gear 306 when moving downward. The second gear 306 will drive the first gear 305 to rotate through the transfer gear 308, and will change the direction of rotation, so that the first gear 305 drives the connecting track 304 to rotate in the opposite direction, and finally drives the uncut galvanized steel sheet to move in a direction away from the profiling mold 11.

As shown in FIGS. 1 to 5 , one end of the inner wall of the conveying frame 301 close to the upper conveying roller 303 is rotatably connected to the lower conveying roller 302 , and the galvanized steel plate is located between the upper conveying roller 303 and the lower conveying roller 302 .

Specifically, by setting the lower conveying roller 302, the galvanized steel sheet is located between the upper conveying roller 303 and the lower conveying roller 302, so that the galvanized steel sheet can be well limited, thereby preventing the galvanized steel sheet from being offset during cutting and affecting the cutting effect.

As shown in FIGS. 3 to 8 , a sensor 310 is provided on one side of the fixed frame 1 , and the sensor 310 is connected to the cutting frame 25 , and a shielding plate 24 is provided below the sliding plate 26 .

Specifically, by setting the baffle plate 24, when the pressing is carried out, the sliding plate 26 will drive the baffle plate 24 to move downward, and finally move to the front end of the sensor 310. The sensor 310 is a photoelectric sensor instrument, and the photodiode on its surface will emit light. When the baffle plate 24 blocks the light emitted by the photodiode, the resistance value of the photodiode changes, thereby generating an electrical signal and transmitting it to the cutting frame 25, so that the cutting frame 25 drives the cutting knife 28 to automatically cut the aluminum-zinc-coated steel plate.

As shown in FIG. 9 , a limiting plate 311 is disposed on the upper surface of the pressing mold 11 , and the limiting plates 311 are located on both sides of the pressing mold 11 .

Specifically, by setting a limit plate 311 on the upper surface of the profiling mold 11, when the aluminum-zinc-coated steel sheet moves to the upper surface of the profiling mold 11, the limit plate 311 can limit the aluminum-zinc-coated steel sheet, thereby preventing the aluminum-zinc-coated steel sheet from shifting during profiling and affecting the profiling effect.

Embodiment 2

As shown in Figures 9 and 10, compared with Example 1, another embodiment of the present invention is: a cleaning structure 4 is provided inside the fixed frame 1 close to the pressing mold 11, and the cleaning structure 4 includes a movable frame 41, one end of the limiting plate 311 is slidably connected to the movable frame 41, and a brush 42 is provided at the lower end of the movable frame 41.

Specifically, since the friction between the corrugation die 11 and the galvanized steel sheet is likely to generate impurities, a movable frame 41 is provided at one end of the corrugation die 11. When the galvanized steel sheet is corrugated into a tile shape, the uncut galvanized steel sheet at the rear will push the corrugated galvanized steel sheet out of the corrugation die 11. At this time, the upper surface of the galvanized steel sheet after corrugation will contact the brush 42, thereby cleaning up the impurities on the upper surface of the galvanized steel sheet after corrugation, and the movable frame 41 will also move toward the direction of the cutting frame 25, thereby cleaning up the impurities on the surface of the corrugation die 11, so that the corrugation effect of the next galvanized steel sheet is better.

As shown in FIGS. 9 and 10 , a sliding shaft 43 is provided on the upper surface of the limiting plate 311 , and the moving frame 41 slides on the surface of the sliding shaft 43 .

Specifically, when the galvanized steel sheet is pressed into a tile shape, the moving frame 41 is started, and the moving frame 41 will drive the brush 42 to move toward the cutting frame 25, so as to clean the impurities in the galvanized steel sheet and the pressing mold 11.

As shown in FIGS. 9 and 10 , a return spring 44 is sleeved on the surface of the sliding shaft 43 , and one end of the return spring 44 is connected to the limit plate 311 , and the other end of the return spring 44 is connected to the moving frame 41 .

Specifically, by setting a reset spring 44, when the moving frame 41 moves to a position close to the cutting frame 25, the moving frame 41 will clean impurities on the surface of the pressing mold 11 during the reset process. At this time, the reset spring 44 will release the elastic force and finally drive the moving frame 41 to reset quickly.

As shown in FIGS. 9 and 10 , one end of the pressing mold 11 close to the moving frame 41 is rotatably connected to a striking frame 45 , and an abutment block 46 is provided at one end of the striking frame 45 .

Specifically, since the impurities generated by the friction between the profiling die 11 and the galvanized steel sheet have a high temperature, they are easily adhered to the surface of the brush 42. For this reason, a knocking frame 45 is provided. After the brush 42 is cleaned once, the knocking frame 45 is started. The knocking frame 45 will drive the abutment block 46 to rotate together, and rotate until it contacts the side wall of the movable frame 41, so that the impurities on the surface of the brush 42 can be separated from the brush 42 by vibration.

As shown in FIG. 10 , a connection spring 47 is provided at one end of the knocking frame 45 , and an abutment block 46 is connected to one end of the connection spring 47 .

Specifically, by providing a connecting spring 47 between the abutting block 46 and the striking frame 45 , the impact force of the abutting block 46 on the moving frame 41 can be weakened, thereby extending the service life of the abutting block 46 .

Working principle: When performing the profiling work, it is only necessary to place the galvanized steel sheet on the surface of the upper conveyor roller 303, and then start the connecting track 304, which will drive the connecting roller 307 to rotate together, and the galvanized steel sheet located between the upper conveyor roller 303 and the lower conveyor roller 302 will move toward the profiling mold 11. When a part of the galvanized steel sheet moves onto the profiling mold 11 and the size is determined, start the cylinder 23, and the cylinder 23 will move downward with the connecting block 27, and the sliding plates 26 at both ends of the connecting block 27 and the corrugated plate 21 at the lower end of the connecting block 27 will move together, and the sliding plate 26 will drive the shielding plate 24 to move downward, and finally move to the front end of the sensor 310. The sensor 310 is a photoelectric sensor, and the photodiode on its surface will emit light. When the shielding plate 24 blocks the light emitted by the photodiode, the resistance value of the photodiode changes, thereby generating an electrical signal and transmitting it to the cutting frame 25. , the cutting frame 25 will drive the cutting knife 28 to move downward, and finally cut the galvanized steel sheet. During cutting, the rack 309 located on one side of the cutting knife 28 will also move downward, and the rack 309 will mesh with the second gear 306 when moving downward, and the second gear 306 will drive the first gear 305 to rotate through the transfer gear 308, and change the direction of rotation, so that the first gear 305 drives the connecting track 304 to rotate in the opposite direction, and finally drives the uncut galvanized steel sheet to move in the direction away from the profiling mold 11, and at this time the profiled plate 21 will contact the galvanized steel sheet, and as the profiled plate 21 continues to move downward, appropriate pressure will be applied to the galvanized steel sheet, when the applied pressure exceeds its yield point, the galvanized steel sheet will begin to plastically deform, and the galvanized steel sheet will undergo plastic deformation under the constraints of the profiled plate 21 and the profiling mold 11, thereby obtaining the desired tile shape, and the profiling of the galvanized steel sheet is completed.
