Description

Technical Field

[0001] This utility model belongs to the field of metal sheet processing technology, and in particular relates to a metal sheet trimming device. Background Technology

[0002] Metal sheet trimming is an important step in metal processing. It aims to use specific processes and equipment to shape and size the edges of metal sheets into the required shapes and sizes while ensuring the smoothness and precision of the edges. Trimming can remove burrs, sharp edges and irregular parts generated during the cutting or stamping of metal sheets, thereby improving the overall quality and aesthetics of the product.

[0003] After metal sheets are processed into sheet-like products, they need to be trimmed. This requires the use of trimming devices. In actual use, existing trimming devices drive a grinding belt to rotate via a transmission roller. Then, the worker holds the sheet-like product and places it against the surface of the grinding belt for grinding. However, during the actual grinding process, the grinding belt rotates at high speed, causing heat to accumulate on its surface. Existing devices are not convenient for using a push plate to cool the grinding belt. Summary of the Invention

[0004] In view of this, the present invention aims to provide a metal sheet trimming device to solve the technical problem that it is inconvenient to use a push plate to cool the grinding belt.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A metal sheet trimming device includes a carrier plate, on which a driving roller and two driven rollers are rotatably mounted in a triangular shape on three sides of the top. The driving roller and the two driven rollers are connected by a grinding belt. The device also includes a push plate, which is a hollow structure and is located inside the grinding belt. A first electric push rod is fixedly connected to one side wall of the push plate and is fixedly connected to the top of the carrier plate. Both sides of the top of the push plate are fixedly connected to conduits. A circulating water assembly is fixedly connected to the rear side wall of the carrier plate.

[0007] It should be understood that, firstly, the metal sheet to be polished is placed on the surface of the carrier plate and made to fit against the polishing belt. Then, the drive roller drives the polishing belt to rotate, thereby using the polishing belt to trim the edge of the metal sheet. During trimming, the first electric push rod drives the push plate to move, thereby pushing the polishing belt to tension and limit it, so that the fit against the edge of the metal sheet is high. At the same time, the circulating water component continuously circulates coolant into the cavity of the push plate, so that the temperature of the polishing belt is transferred to the push plate, and the push plate transfers the temperature to the coolant for heat exchange, thereby reducing the heat accumulation on the polishing belt and thus helping to extend the service life of the polishing belt.

[0008] Furthermore, the circulating water assembly includes a carrier frame, a liquid tank, a liquid pump, and a fixed housing. The carrier frame and the carrier plate are fixedly connected. The liquid tank is fixedly connected to the top of the carrier frame. The liquid pump is fixedly installed on the top of the liquid tank. The inlet end of the liquid pump is inserted into the lower side of the inner cavity of the liquid tank. The other end of the liquid pump is connected to one of the conduits through a hose. The fixed housing is fixedly connected to the top of the liquid tank. The inlet pipe is connected to the top of the fixed housing. The outer end of the inlet pipe is connected to another conduit through a hose.

[0009] Furthermore, a rotating shaft is rotatably mounted on the inner wall of the fixed shell. The rotating shaft passes through the side wall of the fixed shell. Multiple evenly distributed fan blades are fixedly connected to the outer end of the rotating shaft. Multiple evenly distributed blades are fixedly connected to the outer wall of the rotating shaft. The blades are arranged in the inner cavity of the fixed shell. A through hole is opened at the bottom of the inner cavity of the fixed shell. The through hole communicates with the liquid tank. The multiple fan blades are arranged facing the drive roller.

[0010] Specifically, when the water in the inlet pipe returns to the fixed housing, the liquid has a certain pressure, which impacts the blades, causing them to rotate. This, in turn, causes the shaft to rotate, which in turn drives the fan blades to rotate. The fan blades then blow air onto the grinding belt, achieving air cooling of the grinding belt and further improving the cooling effect. Additionally, it blows away debris from the grinding belt, preventing the continuous accumulation of debris from affecting subsequent grinding results.

[0011] Furthermore, it also includes a support assembly, which includes a lifting plate and a second electric actuator. The lifting plate is attached to the top of the carrier plate, and the second electric actuator is fixed to the bottom of the carrier plate. The actuator rod of the second electric actuator passes through the carrier plate and is fixedly connected to the lifting plate.

[0012] Specifically, when grinding metal sheets, the metal sheets are placed on the surface of the lifting plate, which supports the sheet. As the grinding belt is used for a period of time, the lifting plate can be raised and lowered by the second electric actuator, thereby raising and lowering the metal sheet. This allows the sheet to be placed at different positions on the outer wall of the grinding belt, which helps to improve the utilization of the grinding belt and avoids damage caused by excessive local wear.

[0013] Furthermore, it also includes a servo motor, which is fixedly installed at the bottom of the carrier plate corresponding to the active roller. The drive shaft of the servo motor passes through the carrier plate and is fixedly connected to one end of the active roller.

[0014] Furthermore, a strip-shaped hole is provided on the top of the carrier plate corresponding to the side of the grinding belt.

[0015] Furthermore, brackets are fixed on both sides of the bottom of the carrier plate.

[0016] Compared with the prior art, the metal sheet trimming device of this utility model has the following advantages:

[0017] The metal sheet trimming device of this utility model drives the push plate to move through the first electric push rod, thereby pushing the grinding belt and tensioning and limiting the grinding belt. When the grinding belt grinds the metal sheet product, water can be drawn through the push plate by the liquid pump to achieve heat exchange, thereby cooling the grinding belt by the push plate. This helps to avoid the situation where high temperature accumulation causes the grinding belt to be damaged faster.

[0018] The metal sheet trimming device of this utility model uses cooling water drawn by a liquid pump to impact the blades when passing through the fixed shell, thereby driving the rotating shaft to rotate and thus driving the fan blades to rotate. This generates airflow, which blows the air onto the surface of the grinding belt, thereby blowing away the debris adhering to the surface. This helps to prevent debris from accumulating on the grinding belt and affecting the subsequent grinding effect. At the same time, it can also achieve air cooling of the grinding belt, which further improves the cooling effect of the grinding belt.

[0019] The metal sheet trimming device of this utility model extends the coolant return path by having the cooled liquid impact the blades after heat exchange and then return to the liquid tank. This improves the heat dissipation effect of the cooled liquid after heat exchange and enhances the cooling effect of the coolant when used to cool the grinding belt. Attached Figure Description

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1-6 As shown, as an embodiment, the metal sheet trimming device includes a carrier plate 1. The top three sides of the carrier plate 1 are triangularly mounted with a driving roller 14 and two driven rollers 15 respectively. The driving roller 14 and the two driven rollers 15 are connected by a grinding belt 16.

[0034] Specifically, the rotation of the drive roller 14 drives the grinding belt 16 to rotate in conjunction with the driven roller 15, thereby enabling the workpiece to be ground using the rotating grinding belt 16.

[0035] It also includes: a push plate 21, which is a hollow structure and is located inside the grinding belt 16. A first electric push rod 2 is fixedly connected to one side wall of the push plate 21. The first electric push rod 2 is fixedly connected to the top of the carrier plate 1. Both sides of the top of the push plate 21 are fixedly connected to conduits 22. A circulating water assembly is fixedly connected to the rear side wall of the carrier plate 1. The circulating water assembly is used to provide circulating water to the inner cavity of the push plate 21 for cooling.

[0036] It should be understood that in actual use, the metal sheet to be polished is first placed on the surface of the carrier plate 1 and made to fit against the polishing belt 16. Then, the drive roller 14 drives the polishing belt 16 to rotate, thereby using the polishing belt 16 to trim the edge of the metal sheet. During trimming, the first electric push rod 2 drives the push plate 21 to move, thereby pushing the polishing belt 16 to tension and limit it, so that the fit is high when polishing the edge of the metal sheet. At the same time, the circulating water component continuously circulates and introduces coolant into the cavity of the push plate 21, so that the temperature on the polishing belt 16 is transferred to the push plate 21, and the push plate 21 transfers the temperature to the coolant for heat exchange, thereby reducing the heat accumulation on the polishing belt 16, which helps to extend the service life of the polishing belt 16.

[0037] It is worth mentioning that a strip hole 12 is provided on the top of the carrier plate 1 on the side corresponding to the grinding belt 16. The setting of the strip hole 12 allows the grinding debris to fall through the strip hole 12 and descend, so that the waste can be collected by the receiving box, which helps to prevent the debris from accumulating on the carrier plate 1.

[0038] Specifically, brackets 11 are fixed on both sides of the bottom of the carrier plate 1. The brackets 11 support the carrier plate 1 at a certain height, which makes it convenient for the staff to operate.

[0039] like Figure 1-2As shown in the figure, as an embodiment, the circulating water assembly includes a carrier 3, a liquid tank 31, a liquid pump 32, and a fixed housing 33. The carrier 3 and the carrier plate 1 are fixedly connected. The liquid tank 31 is fixedly connected to the top of the carrier 3. The liquid pump 32 is fixedly installed on the top of the liquid tank 31. The liquid inlet end of the liquid pump 32 is inserted into the lower side of the inner cavity of the liquid tank 31. The other end of the liquid pump 32 is connected to one of the conduits 22 through a hose. The fixed housing 33 is fixedly connected to the top of the liquid tank 31. The water inlet pipe 34 is connected to the top of the fixed housing 33. The outer end of the water inlet pipe 34 is connected to another conduit 22 through a hose.

[0040] It should be understood that the coolant in the inner cavity of the liquid tank 31 can be drawn by the liquid pump 32 into the conduit 22 on one side, so that the coolant enters the cavity of the push plate 21, and then the coolant undergoes heat exchange. After heat exchange, the coolant returns to the fixed shell 33 through another conduit 22 and then enters the liquid tank 31, thereby realizing the recycling of coolant for cooling.

[0041] like Figure 5-6 As shown in the figure, in one embodiment, a rotating shaft 35 is rotatably mounted on the inner wall of the fixed shell 33. The rotating shaft 35 passes through the side wall of the fixed shell 33. A plurality of evenly distributed fan blades 36 are fixedly connected to the outer end of the rotating shaft 35. A plurality of evenly distributed blades 37 are fixedly connected to the outer wall of the rotating shaft 35. The blades 37 are disposed in the inner cavity of the fixed shell 33. A through hole is opened at the bottom of the inner cavity of the fixed shell 33. The through hole communicates with the liquid tank 31. The plurality of fan blades 36 are arranged facing the drive roller 14.

[0042] It should be understood that when the water in the inlet pipe 34 returns to the fixed shell 33, the liquid has a certain pressure, which will impact the blades 37, causing the blades 37 to rotate, which in turn causes the shaft 35 to rotate, which in turn causes the fan blades 36 to rotate. The fan blades 36 can then blow air, which is directed towards the grinding belt 16, thereby achieving air cooling of the grinding belt 16 and further improving the cooling effect. It can also blow away the debris on the grinding belt 16, thus preventing the continuous accumulation of debris on the grinding belt 16 from affecting the subsequent grinding effect.

[0043] like Figure 1-5 As shown, in one embodiment, it also includes a support assembly, which includes a lifting plate 13 and a second electric push rod 17. The lifting plate 13 is attached to the top of the carrier plate 1, and the second electric push rod 17 is fixed to the bottom of the carrier plate 1. The push rod of the second electric push rod 17 passes through the carrier plate 1 and is fixedly connected to the lifting plate 13.

[0044] It should be understood that when grinding metal sheets, the metal sheets are placed on the surface of the lifting plate 13, which supports the sheet. As the grinding belt 16 is used for a period of time, the second electric push rod 17 can drive the lifting plate 13 to rise and fall, thereby driving the metal sheet to rise and fall, so as to fit against different positions on the outer wall of the grinding belt 16. This helps to improve the full utilization of the grinding belt 16 and avoids excessive local wear and damage to the grinding belt 16.

[0045] like Figure 3 As shown, in one embodiment, a servo motor 18 is also included. The servo motor 18 is fixedly installed at the bottom of the carrier plate 1 corresponding to the active roller 14. The drive shaft of the servo motor 18 passes through the carrier plate 1 and is fixedly connected to one end of the active roller 14.

[0046] It should be understood that the servo motor 18 drives the active roller 14 to rotate, thereby driving the grinding belt 16 to rotate.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
