Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel plate production technology, and in particular to a deburring machine for cold-rolled steel plates. Background Technology

[0002] Cold-rolled steel sheet is steel produced by removing the oxide scale from hot-rolled steel sheet and then rolling it at room temperature using a cold rolling mill. It has high thickness precision, a smooth and flat surface, and superior mechanical properties (such as improved strength and hardness). Its properties can also be optimized through annealing, galvanizing, and other treatments. It is widely used in automobiles, home appliances, electronic equipment and other fields, and can meet the requirements of high appearance and structural strength of sheet materials.

[0003] A search revealed that the document with publication number "CN222570177U" states that "this utility model relates to the field of deburring machine technology, and discloses a deburring machine for cold-rolled steel plates. A top plate is provided above a bottom plate, and a height adjustment component is provided on the bottom plate to adjust the height of the top plate. The top plate has symmetrical slots on both sides, and a mounting block is provided below the slots. A grinding roller is rotatably connected to the lower end face of the mounting block, and a motor is provided on the upper end face of the mounting block to drive the grinding roller to rotate. A position adjustment component is provided in the middle section of the upper end face of the top plate to adjust the position of a cylinder. A frame is provided above the top plate, and the piston rod of the cylinder is connected to the frame. The frame has symmetrical slots on both sides, and a movable block is slidably connected within the slots. The movable block is connected to the mounting block via a connecting rod. A bidirectional cylinder is provided on the upper end face of the frame, and the piston rod of the bidirectional cylinder is connected to the movable block." In use, this machine can thoroughly deburr cold-rolled steel plates of different specifications and sizes.

[0004] However, during the grinding process of cold-rolled steel sheets, a lot of burrs and metal chips are easily generated on the surface. Conventional grinding equipment often uses simple mechanical scraping during the grinding process, which is slow and the grinding effect on the upper and lower surfaces is prone to unevenness, affecting the production quality of the steel sheet. In addition, during the feeding process, the steel sheet is mostly directly wound by a coiler, which is prone to deformation due to insufficient winding buffer.

[0005] Therefore, we provide a cold-rolled steel plate deburring machine to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A deburring machine for cold-rolled steel sheets includes a support base. A conveying assembly is provided at the upper right end of the support base. The conveying assembly includes a lower support base installed at the upper right end of the support base. A forward rotation motor is installed on the outer side of the lower support base. A feeding rotation shaft is installed in the middle of the lower support base.

The steel sheet grinding assembly includes a lower grinding base located at the upper middle of the support base. A reverse rotation motor is installed on the rear side of the lower grinding base.

An upper grinding abrasive is provided on the upper side of the lower grinding abrasive. A connecting gear is provided on the front side of the grinding roller. A steel sheet limiting assembly is provided at the upper left end of the support base.

[0007] As a further description of the above technical solution: A lifting hydraulic rod is welded to the upper side of the lower support base, and an upper support base is welded to the upper side of the lifting hydraulic rod. An upper clamping driven rubber pad is provided in the middle of the upper support base. A cold-rolled steel plate passes through the middle of the upper clamping driven rubber pad and the lower rubber pad. The feeding rotary shaft is axially connected to the forward rotary motor. The forward rotary motor drives the forward rotary motor to rotate in the forward direction through the feeding rotary shaft. The upper clamping driven rubber pad rotates driven by the upper support base. The lower rubber pad drives the upper clamping driven rubber pad to rotate driven by the cold-rolled steel plate.

[0008] As a further description of the above technical solution: The lifting hydraulic rod is welded to the upper support base, and the upper support base and the lower support base form a lifting structure through the lifting hydraulic rod.

[0009] As a further description of the above technical solution: The grinding roller and the reverse rotation motor are connected by a shaft. The reverse rotation motor drives the lower grinding pad to rotate in the reverse direction through the grinding roller. The upper grinding pad and the grinding roller are connected by a gear to form a driven rotation structure.

[0010] As a further description of the above technical solution: The lower grinding base is welded with an adsorption bracket on its right side. The adsorption bracket is connected to an adsorption beam plate through a slot on its inner side. A magnetic electromagnet is installed on the inner side of the adsorption beam plate. The adsorption beam plates are arranged in two symmetrical groups, one above the other. The cold-rolled steel plate passes through the middle of the adsorption beam plate.

[0011] As a further description of the above technical solution: The steel plate limiting assembly includes a side limiting plate installed on the upper left side of the support base plate. The inner shaft of the side limiting plate is connected to a limiting wheel. The limiting wheel is connected to the cold-rolled steel plate body by a slot. The limiting wheel is arranged in two symmetrical sets in the front and rear.

[0012] As a further description of the above technical solution: A lower driven shaft wheel is provided on the left side of the side limiting plate. A limiting lifting hydraulic rod is installed on the upper side of the lower driven shaft wheel. An upper driven shaft wheel is installed on the upper side of the limiting lifting hydraulic rod. The lower driven shaft wheel and the upper driven shaft wheel form a lifting structure through the limiting lifting hydraulic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a conveying assembly. When needed, the cold-rolled steel plate is placed between the lower rubber pad and the upper clamping driven rubber pad. The forward rotation motor is started, and the lower rubber pad on the surface of the feeding rotating shaft drives the cold-rolled steel plate forward. Simultaneously, the upper clamping driven rubber pad rotates driven by the cold-rolled steel plate. This frictional force ensures stable forward conveying of the cold-rolled steel plate, effectively performing the feeding operation and resisting the reverse rotational force of the grinding shaft, thus guaranteeing the continuity and stability of the feeding. After the cold-rolled steel plate is placed between the lower and upper clamping driven rubber pads, the lifting hydraulic rod retracts inward, causing the upper support base to move downward, making the upper clamping driven rubber pad press tightly against the cold-rolled steel plate, thus providing sufficient friction. Furthermore, the lifting hydraulic rod extends outward when placing the cold-rolled steel plate, facilitating placement and improving operational convenience.

[0014] 2. This utility model utilizes a steel plate grinding assembly. The cold-rolled steel plate passes between the upper and lower grinding pads. As the lower pad moves forward, the cold-rolled steel plate moves forward. Simultaneously, a reverse-rotating motor drives the grinding roller to rotate the lower grinding pad in the opposite direction. This, along with the upper grinding pad, forms a bidirectional friction grinding effect on the surface of the cold-rolled steel plate through connecting gears, achieving efficient and uniform grinding. During the grinding process, as the lower and upper grinding pads grind the cold-rolled steel plate, the resulting debris is thrown into the adsorption beams within the adsorption bracket as the pads rotate. The magnetic electromagnets within the adsorption beams generate a magnetic field when energized, firmly adsorbing the debris onto the inner side of the adsorption beams, preventing debris from splashing and polluting the working environment, and effectively protecting the health of the operators. Furthermore, the symmetrical design of the two sets of adsorption beams ensures that the adsorption range covers both the upper and lower surfaces of the cold-rolled steel plate, enhancing the adsorption effect.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4As shown, this utility model provides a technical solution: a deburring machine for cold-rolled steel plates, wherein a conveying assembly 2 is provided on the upper right end of a support base 1, the conveying assembly 2 includes a lower support base 201 installed on the upper right end of the support base 1, a forward rotation motor 202 is installed on the outer side of the lower support base 201, a feeding rotation shaft 203 is installed in the middle of the lower support base 201, a lower rubber pad 204 is provided on the surface of the feeding rotation shaft 203, and a steel plate grinding assembly 3 is provided in the middle of the upper side of the support base 1. The steel plate grinding assembly 3 includes a lower grinding base 301 disposed in the middle of the upper side of the support base 1, a reverse rotation motor 302 installed on the rear side of the lower grinding base 301, a grinding roller 303 connected in the middle of the lower grinding base 301, a lower grinding abrasive 304 installed on the surface of the grinding roller 303, an upper grinding abrasive 305 disposed on the upper side of the lower grinding abrasive 304, a connecting gear 306 disposed on the front side of the grinding roller 303, and a steel plate limiting assembly 4 disposed on the upper left side of the support base 1.

[0019] Furthermore, a lifting hydraulic rod 205 is welded to the upper side of the lower support base 201, and an upper support base 206 is welded to the upper side of the lifting hydraulic rod 205. An upper clamping driven rubber pad 207 is provided in the middle of the upper support base 206. A cold-rolled steel plate 208 passes through the middle of the upper clamping driven rubber pad 207 and the lower rubber pad 204. The feeding rotary shaft 203 is axially connected to the forward rotary motor 202. The forward rotary motor 202 is driven to rotate forward through the feeding rotary shaft 203. The upper clamping driven rubber pad 207 and the upper support base 206 rotate driven. The lower rubber pad 204 is formed by cold rolling... The steel plate 208 drives the upper clamping driven rubber pad 207 to rotate passively. When needed, the cold-rolled steel plate 208 is placed between the lower rubber pad 204 and the upper clamping driven rubber pad 207. The forward rotation motor 202 is started, and the lower rubber pad 204 on the surface of the feeding rotating shaft 203 drives the cold-rolled steel plate 208 to be conveyed forward. At this time, the upper clamping driven rubber pad 207 rotates passively under the drive of the cold-rolled steel plate 208. In this way, the cold-rolled steel plate 208 is stably conveyed forward through friction, which can effectively perform the feeding operation and resist the reverse rotation force of the grinding shaft 303, thereby ensuring the continuity and stability of the feeding.

[0020] Furthermore, the lifting hydraulic rod 205 is welded to the upper support base 206. The upper support base 206 and the lower support base 201 form a lifting structure through the lifting hydraulic rod 205. When needed, the cold-rolled steel plate 208 is placed between the lower rubber pad 204 and the upper clamping driven rubber pad 207. The lifting hydraulic rod 205 retracts inward, causing the upper support base 206 to move downward, so that the upper clamping driven rubber pad 207 presses tightly against the cold-rolled steel plate 208, thereby providing sufficient friction. When placing the cold-rolled steel plate 208, the lifting hydraulic rod 205 extends outward, which facilitates the placement of the cold-rolled steel plate 208, thereby improving the ease of operation.

[0021] Furthermore, the grinding roller 303 and the reverse rotation motor 302 are connected by a shaft. The reverse rotation motor 302 drives the lower grinding pad 304 to rotate in the reverse direction through the grinding roller 303. The upper grinding pad 305 and the grinding roller 303 form a driven rotation structure through the connecting gear 306. When needed, the cold-rolled steel plate 208 passes between the upper grinding pad 305 and the lower grinding pad 304. As the lower pad 204 is driven, the cold-rolled steel plate 208 moves forward. At the same time, the reverse rotation motor 302 drives the grinding roller 303 to drive the lower grinding pad 304 to rotate in the reverse direction. Together with the upper grinding pad 305, they form a bidirectional friction grinding effect on the surface of the cold-rolled steel plate through the connecting gear 306, thereby achieving efficient and uniform grinding operation.

[0022] Furthermore, an adsorption bracket 307 is welded to the right side of the lower grinding base 301. An adsorption beam plate 308 is connected to the inner groove of the adsorption bracket 307. A magnetic electromagnet 309 is installed on the inner side of the adsorption beam plate 308. The adsorption beam plates 308 are arranged symmetrically in two sets, upper and lower. The cold-rolled steel plate 208 passes through the middle of the adsorption beam plate 308. During the grinding process, as the lower grinding sandpaper 304 and the upper grinding sandpaper 305 grind the cold-rolled steel plate 208, the generated debris will be... The rotation of the lower and upper grinding sandpaper 304 and the upper grinding sandpaper 305 throws them into the adsorption beam plate 308 inside the adsorption bracket 307. When the magnetic electromagnet 309 inside the adsorption beam plate 308 is energized, it generates a magnetic field, which firmly adsorbs the debris onto the inner side of the adsorption beam plate 308, preventing debris from splashing and polluting the working environment, and effectively protecting the health of the operators. At the same time, the symmetrical design of the upper and lower adsorption beam plates 308 allows the adsorption range to cover the upper and lower surfaces of the cold-rolled steel plate 208, improving the adsorption effect.

[0023] Furthermore, the steel plate limiting assembly 4 includes a side limiting plate 401 installed on the upper left side of the support base plate 1. The inner shaft of the side limiting plate 401 is connected to a limiting wheel 402. The limiting wheel 402 and the cold-rolled steel plate 208 are connected by a slot. The limiting wheels 402 are arranged in two symmetrical sets. When needed, the cold-rolled steel plate 208 passes through the slot of the limiting wheel 402. The lateral movement of the cold-rolled steel plate 208 is limited by the two sets of limiting wheels 402, ensuring that it maintains stable linear motion during the conveying process and avoiding uneven grinding or equipment damage caused by deviation. At the same time, the limiting wheel 402 is made of wear-resistant alloy material, with a smooth surface and low coefficient of friction, which effectively reduces the resistance of the cold-rolled steel plate 208 during the conveying process and improves the smoothness of operation.

[0024] Furthermore, a lower driven shaft wheel 403 is provided on the left side of the side limiting plate 401. A limiting lifting hydraulic rod 404 is installed on the upper side of the lower driven shaft wheel 403, and an upper driven shaft wheel 405 is installed on the upper side of the limiting lifting hydraulic rod 404. The lower driven shaft wheel 403 and the upper driven shaft wheel 405 form a lifting structure through the limiting lifting hydraulic rod 404. When needed, the height of the upper driven shaft wheel 405 is adjusted by controlling the limiting lifting hydraulic rod 404 so that it and the lower driven shaft wheel 403 together clamp the cold-rolled steel plate 208, thereby achieving feeding stability. Idle speed machines are installed at the ends of both the upper driven shaft wheel 405 and the lower driven shaft wheel 403, which play a buffering and adjustment role during the conveying of the cold-rolled steel plate 208.

[0025] Working principle: When needed, the support base plate 1 is fixed to the desired position. Then, the cold-rolled steel plate 208 passes through the middle of the lower driven shaft wheel 403 and the upper driven shaft wheel 405, then through the middle of the lower grinding sandpaper 304 and the upper grinding sandpaper 305, until it passes through the middle of the lower rubber pad 204 and the upper clamping driven rubber pad 207. After preparation, the lifting hydraulic rod 404 drives the upper driven shaft wheel 405 downward to clamp the cold-rolled steel plate 208. The lifting hydraulic rod 205 drives the upper clamping driven rubber pad 207 downward through the upper support base 206. After preparation, the forward rotation motor 202, through the feeding rotation shaft 203, cooperates with the lower rubber pad 204 and the upper clamping driven rubber pad 207 to drive the cold-rolled steel plate 208 to rotate forward. As the cold-rolled steel sheet 208 is pulled out, the reverse rotation motor 302 outside the lower grinding base 301 drives the lower grinding abrasive 304 to rotate in the opposite direction through the grinding shaft 303. The grinding shaft 303 drives the upper grinding abrasive 305 to rotate synchronously through the connecting gear 306, thereby completing the grinding operation on the cold-rolled steel sheet 208. The metal debris generated during grinding is thrown into the adsorption bundle plate 308 inside the adsorption bracket 307. The magnetic electromagnet 309 inside the adsorption bundle plate 308 is energized, thereby adsorbing the metal debris onto the inner surface of the adsorption bundle plate 308. During the pulling process, the cold-rolled steel sheet 208 is positioned by the limiting shaft wheel 402 inside the side limiting plate 401. This completes the use process of a cold-rolled steel sheet deburring machine.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
