Description

Technical Field

[0001] This invention relates to the field of stainless steel plate processing technology, and more specifically, to a trimming device for stainless steel plate processing and its method of use. Background Technology

[0002] Stainless steel sheet refers to steel with a chromium-based oxide film on its surface, giving it excellent corrosion resistance, wear resistance, and aesthetic appeal. It is widely used in industrial production and daily life, such as in architectural decoration, kitchenware, and medical devices. However, during the production process, the edges of stainless steel sheets are often not neat enough, potentially exhibiting burrs and unevenness. This not only affects the appearance quality of the stainless steel sheet but may also pose safety hazards during subsequent processing and use. Therefore, edge trimming of stainless steel sheets is essential. Professional edge trimming equipment can cut the edges of stainless steel sheets more neatly and smoothly, improving the quality and performance of the sheet. Moreover, with continuous technological advancements, edge trimming equipment is constantly being upgraded, significantly improving cutting precision and efficiency to better meet the edge trimming needs of various industries.

[0003] According to patent document CN118268874B, a stainless steel door sheet shearing device is disclosed, relating to the field of manufacturing equipment technology. It includes a base plate, a shearing mechanism for shearing stainless steel sheets at one top end of the base plate, a vibration mechanism for tidying the stainless steel sheets on one side of the shearing mechanism, a rotating mechanism for providing power at the top center of the base plate, and a placement mechanism for placing the stainless steel sheets at the top of the rotating mechanism. This invention, by setting up a grinding mechanism and a placement mechanism, enables the grinding and deburring operations on the sheared ends of the stainless steel sheets, improving the production efficiency of stainless steel doors. Furthermore, by setting up a driving mechanism, a placement mechanism, and a feeding mechanism, this invention enables the automatic stacking and feeding of stainless steel sheets, improving the shearing efficiency of the stainless steel sheets and further enhancing the processing efficiency of stainless steel doors.

[0004] When trimming stainless steel sheets, the conventional operation is to place the sheet directly on the cutting platform and use a cutting wheel to complete the trimming process. However, this method may have several drawbacks. First, the stainless steel sheet placed directly is prone to displacement during the cutting process, making it difficult to control the trimming accuracy and potentially causing deviations in the dimensions of the cut sheet, which in turn affects subsequent use and installation. Second, due to the high density and hardness of stainless steel sheets, the cutting wheel is prone to wear when cut using a fixed-shape cutting wheel, requiring frequent replacement, increasing production costs, and reducing cutting efficiency. Third, the metal shavings generated during the cutting process will fly in all directions, posing a potential threat to the safety of operators and polluting the working environment, increasing the difficulty of cleanup. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides a cutting device and its method for processing stainless steel plates. The technical problem to be solved by the present invention is that stainless steel plates placed directly are prone to displacement during the cutting process, making it difficult to control the cutting accuracy and causing deviations in the dimensions of the cut plates, which in turn affects subsequent use and installation. Due to the high density and hardness of stainless steel plates, when using a fixed-shape cutting wheel for cutting, the cutting wheel is prone to wear, which not only requires frequent replacement, increasing production costs, but also reduces cutting efficiency.

Steel plates are fixedly connected to the outer center of the two sets of L-shaped connecting uprights on the left and the two sets of L-shaped connecting uprights on the right.

[0015] In addition, the present invention also relates to a trimming device for processing stainless steel plates and a method of using the same, comprising the following steps: Step 1: Push the stainless steel sheet to the top of the lifting plate through the top of the two steel plate guide side plates, so that the part of the stainless steel sheet that needs to be trimmed is at the bottom of the two cutting pieces; Step 2: Start the electric push rod, push the semi-circular push block to move the lifting plate to the top. During the lifting plate's ascent, the rotating arm and the second rotating arm rotate around the columnar central axis, and the slide plate slides to the right on the slide rail, stably lifting the lifting plate. Step 3: When the stainless steel plate at the top of the lifting plate is in contact with the bottom of the two cutting pieces, the Z-shaped rotating block with the concave hinge block as the axis is pushed by the round H-shaped sleeve block and rotates due to the continuous push of the electric push rod. The spring is compressed to provide buffer for the cutting edge. Step 4: The rotation of the two sets of Z-shaped rotating blocks drives the two sets of push-pull uprights to move downwards and press down on the H-shaped plate. The descent of the H-shaped plate drives the two L-shaped lifting uprights to descend synchronously. Step 5: As the L-shaped lifting platform descends, the horizontal hinge rod moves down, the rotating rod rotates around the horizontal hinge rod, pushing the protective cover downward. The protective cover slides down along the arc-shaped guide side plate trajectory, covering the cut piece and stainless steel plate. Step Six: Start the motor. The motor drives the transmission disc to rotate, and transmits power to the second transmission disc at the front through the track. The second track then drives the other second transmission discs to rotate, causing the cylindrical rotating block and the cutting wheel to rotate at high speed. The larger cutting wheel at the front first performs a preliminary large-area cut on the edge of the stainless steel plate, and the smaller cutting wheel further trims the edge after the preliminary cut. Step 7: Activate the second electric push rod to push the convex push-pull plate, causing the two cutting parts to move back and forth to cut the stainless steel plate. The reciprocating motion of the convex push-pull plate is precisely synchronized with the rotation speed of the cutting wheel.

[0016] The beneficial effects of this invention are as follows: This invention automates and refines the stainless steel sheet trimming process by incorporating a trimming table and protective components. Through ingenious mechanical design, all components work collaboratively, seamlessly completing the entire process from stainless steel sheet loading and positioning, to the stable lifting of the hoisting structure, the automatic application of the protective cover, and the high-speed rotation and forward / backward movement of the cutting wheels. This not only improves trimming efficiency but also ensures trimming precision and quality, avoiding excessive pressure on the stainless steel sheet and problems such as burrs and skipped cuts during the trimming process. Furthermore, this design simplifies the operation of the trimming device, reduces manual labor intensity, and minimizes the impact of human factors on trimming quality. In actual production, it can adapt to stainless steel sheets of different specifications and trimming requirements, exhibiting strong versatility and practicality. It provides the stainless steel sheet processing industry with an efficient and reliable trimming solution, contributing to improved production levels and product quality across the industry.

Concave guide blocks 12110 are fixedly connected to the outer sides of both sets of left and right concave hinge blocks 1219. Springs 12111 are fixedly connected to both sides of the bottom outer sides of both sets of left and right Z-shaped rotating blocks 1216.The bottom ends of multiple sets of springs 12111 are all fixedly connected to the top of the left and right sets of concave guide blocks 12110. The inner sides of the left and right sets of concave hinge blocks 1219 are all fixedly connected to the front and rear sides of the left and right sides of the lifting plate 1114. The bottom of the two L-shaped side plates 1213 are all fixedly connected to the cutting parts 12113. The front side of the top of the two cutting parts 12113 is fixedly connected to the convex push-pull plate 12112. The middle part of the rear side of the convex push-pull plate 12112 is fixedly connected to the front end of the second electric push rod 1212. The two cutting parts 12113 each include a cutting part shell 121131. The top of the rear side of the two cutting part shells 121131 is fixedly connected to the motor connecting block 121132. The bottom of the two motor connecting blocks 121132 is fixedly connected to... Motor 121133, the output ends of both motors 121133 are fixedly connected to transmission discs 121134, multiple sides of the inner wall of the two cutting part housings 121131 are rotatably connected to columnar rotating blocks 121136, the right side of the outer wall of the multiple columnar rotating blocks 121136 is fixedly connected to cutting wheels 121137, the left side of the outer wall of the multiple columnar rotating blocks 121136 is fixedly connected to second transmission discs 121138, the outer wall of both transmission discs 121134 is fitted with tracks 121135, the inner wall of both tracks 121135 away from motor 121133 is fitted onto the outer wall of the two foremost second transmission discs 121138, and the outer walls of the left and right sets of second transmission discs 121138 are fitted with second tracks 121139; When the stainless steel plate needs to be trimmed, the stainless steel plate is first pushed to the top of the lifting plate 1114 through the top of the two steel plate guide side plates 1223. At this time, the part of the stainless steel plate that needs to be trimmed is at the bottom of the two cutting parts 12113. Then, the electric push rod 114 is activated to push the semi-circular push block 1116 to move the lifting plate 1114 to the top. During the process of the lifting plate 1114 rising, the rotating arm 118 and the second rotating arm 1110 rotate around the columnar central rod 1111. At the same time, the slide plate 116 slides to the right on the slide rail 115, so that the entire lifting structure stably lifts the lifting plate 1114 upward. As the lifting plate 1114 rises, the stainless steel plate also rises. At this point, when the stainless steel plate at the top of the lifting plate 1114 is in contact with the bottom of the two cutting pieces 12113, the electric push rod 114 continuously pushes the lifting plate 1114 to move upwards. This causes the Z-shaped rotating block 1216, with the concave hinge block 1219 as its axis, to rotate under the push of the circular H-shaped sleeve block 1215. The spring 12111 is compressed, providing a buffer for the subsequent cutting process and preventing excessive pressure on the stainless steel plate, which could then damage it. After that, the motor 121133 can be started. The motor 121133 drives the transmission disc 121134 to rotate, transmitting power to the foremost second transmission disc 121138 via the track 121135, and then the second track 121139 drives... The other second transmission disc 121138 rotates, which in turn causes the cylindrical rotating block 121136 and the cutting wheel 121137 to rotate at high speed. The multiple cutting wheels 121137 are designed to decrease in size from front to back. This design allows for progressively refined edge cutting operations based on the edge cutting requirements of different positions on the stainless steel plate. The larger cutting wheel 121137 at the front first performs a preliminary large-area cut on the edge of the stainless steel plate, removing a large portion of the excess scrap material to prepare for subsequent fine cutting. The smaller cutting wheel 121137 then further trims the edges after the preliminary cut, making the cut edges smoother and neater, ensuring the precision and quality of the cut edges. Simultaneously, the second electric push rod 1212 is activated, pushing the convex push-pull plate 12112, causing the two cutting pieces 12113 to move back and forth to perform edge trimming on the stainless steel plate. Due to the size differences and high-speed rotation of the multiple cutting wheels 121137, the edge trimming work can be completed more efficiently during the back and forth movement, further improving the quality and efficiency of edge trimming. Throughout the edge trimming process, the coordinated work of the electric push rod 114 and the second electric push rod 1212 ensures that the lifting plate 1114 and the back and forth movement of the cutting pieces 12113 are precisely coordinated, achieving all-round, high-precision edge trimming of the stainless steel plate. After edge trimming is completed, the motor 121133, electric push rod 114, and the second electric push rod 1212 are turned off, and the edge-trimmed stainless steel plate is removed from the lifting plate 1114, ending the entire edge trimming process. Through reasonable structural design and coordinated operation of various components, the entire device greatly improves the efficiency and quality of stainless steel plate edge trimming, meeting the needs of actual production.

[0022] like Figure 9-10As shown, both connecting frames 122 include two sets of L-shaped connecting uprights 1221. The inner sides of the two sets of L-shaped connecting uprights 1221 on the left and the two sets of L-shaped connecting uprights 1221 on the right are slidably connected to convex sliders 1222. The inner sides of the two sets of convex sliders 1222 are fixedly connected to the front and rear sides of the left and right sides of the base plate 111. The tops of the two sets of L-shaped connecting uprights 1221 on the left and the two sets of L-shaped connecting uprights 1221 on the right are fixedly connected to the two sets of concave guide blocks 12110 on the left and right. At the bottom, steel plate guide side plates 1223 are fixedly connected to the outer middle of the two sets of L-shaped connecting uprights 1221 on the left and the two sets of L-shaped connecting uprights 1221 on the right. L-shaped connecting side plates 1225 are fixedly connected to the outer middle of the two steel plate guide side plates 1223. Arc-shaped guide side plates 1226 are fixedly connected to the outer sides of the two L-shaped connecting side plates 1225. Push-pull uprights 1224 are slidably connected to both sides of the rear outer sides of the two steel plate guide side plates 1223. The two sets of push-pull uprights 1224 on the left and right are also connected to the steel plate guide side plates 1223. The tops of the two sets of Z-shaped rotating blocks 1216 are fixedly connected to the outer sides of the bottom of the two sets of Z-shaped rotating blocks 1216. The outer walls of the two sets of push-pull uprights 1224 are slidably connected to the inner walls of the two sets of concave guide blocks 12110. The bottoms of the two sets of push-pull uprights 1224 are fixedly connected to the four sides of the top of the H-shaped plate 1115. The protective component 2 includes two L-shaped lifting uprights 21. The bottoms of the two L-shaped lifting uprights 21 are fixedly connected to the left and right sides of the top of the H-shaped plate 1115. The top of the outer side of 21 is fixedly connected with a horizontal hinge rod 22. The outer side of the two horizontal hinge rods 22 is rotatably connected with a rotating rod 23. The top of the inner side of the two rotating rods 23 is rotatably connected with a protective cover 24.

The bottom front sides of the left and right sides of the inner wall of the protective cover 24 are rotatably connected to the outer side of the two L-shaped connecting side plates 1225. When the two sets of Z-shaped rotating blocks 1216 rotate, they drive the two sets of push-pull uprights 1224 to move downward and press the H-shaped plate 1115. The descent of the H-shaped plate 1115 will drive the two L-shaped lifting uprights 21 to descend synchronously. As the L-shaped lifting uprights 21 descend, the position of the horizontal hinge rod 22 will also move downward. The rotating rod 23 will rotate around the horizontal hinge rod 22, thereby pushing the protective cover 24 to move downward. Since the outer wall of the protective cover guide block 25 is slidably connected to the inner side of the arc-shaped guide side plate 1226, the protective cover 24 will slide downward along the trajectory of the arc-shaped guide side plate 1226 until it covers the cut piece 12113 and the stainless steel plate. The design of this protective cover 24 provides excellent protection. During the cutting process, the high-speed rotating cutting wheel 121137 generates a large amount of debris. The protective cover 24 can prevent these debris from splashing out, avoiding injury to the operator, and also reducing the pollution of the working environment by the debris. Moreover, the opening and closing of the protective cover 24 is closely related to the lifting action of the cutting device. When the lifting plate 1114 rises to make the stainless steel plate fit against the cutting part 12113 in preparation for cutting, the protective cover 24 will automatically descend to cover. When the cutting is completed, the lifting plate 1114 descends, the two sets of Z-shaped rotating blocks 1216 rotate in opposite directions, the push-pull upright 1224 moves upward, the L-shaped lifting upright 21 rises, and the protective cover 24 will slide upward along the arc-shaped guide side plate 1226 to open, making it convenient for the operator to take out the cut stainless steel plate. In addition, the bottom front sides of the left and right sides of the inner wall of the protective cover 24 are rotatably connected to the outside of the two L-shaped connecting side plates 1225. This design ensures the stability of the protective cover 24 during movement, enabling it to open and close accurately according to the predetermined trajectory, further improving the safety and reliability of the entire edge cutting device, and ensuring that the edge cutting work can be carried out efficiently and safely.

[0023] In addition, the present invention also relates to a trimming device for processing stainless steel plates and a method of using the same, comprising the following steps: Step 1: Push the stainless steel plate to the top of the lifting plate 1114 through the top of the two steel plate guide side plates 1223, so that the part of the stainless steel plate that needs to be trimmed is at the bottom of the two cutting pieces 12113. Step 2: Start the electric push rod 114, push the semi-circular push block 1116 to move the lifting plate 1114 to the top. During the process of the lifting plate 1114 rising, the rotating arm 118 and the second rotating arm 1110 rotate around the columnar central rod 1111, and the slide plate 116 slides to the right on the slide rail 115 to stably lift the lifting plate 1114. Step 3: When the stainless steel plate at the top of the lifting plate 1114 is in contact with the bottom of the two cutting pieces 12113, the Z-shaped rotating block 1216, which is centered on the concave hinge block 1219, is pushed by the round H-shaped sleeve block 1215 and rotates due to the continuous push of the electric push rod 114. The spring 12111 is compressed, providing a buffer for the cutting edge. Step 4: The rotation of the two sets of Z-shaped rotating blocks 1216 drives the two sets of push-pull uprights 1224 to move downwards and press down on the H-shaped plate 1115. The H-shaped plate 1115 descends, causing the two L-shaped lifting uprights 21 to descend synchronously. Step 5: As the L-shaped lifting plate 21 descends, the horizontal hinge rod 22 moves down, the rotating rod 23 rotates around the horizontal hinge rod 22, pushing the protective cover 24 to move downward. The protective cover 24 slides down along the trajectory of the arc-shaped guide side plate 1226, covering the cutting piece 12113 and the stainless steel plate. Step Six: Start motor 121133. Motor 121133 drives transmission disc 121134 to rotate. Through track 121135, the power is transmitted to the foremost second transmission disc 121138. Then, the second track 121139 drives the other second transmission discs 121138 to rotate, causing the cylindrical rotating block 121136 and the cutting wheel 121137 to rotate at high speed. The larger cutting wheel 121137 at the front first performs a preliminary large-area cut on the edge of the stainless steel plate, and the smaller cutting wheel 121137 further trims the edge after the preliminary cut. Step 7: Start the second electric push rod 1212 to push the convex push-pull plate 12112, so that the two cutting parts 12113 move back and forth to cut the stainless steel plate. The reciprocating motion of the convex push-pull plate 12112 is precisely synchronized with the rotation speed of the cutting wheel 121137.

[0024] Working principle of this invention: When it is necessary to trim the stainless steel plate, the stainless steel plate is first pushed to the top of the lifting plate 1114 through the top of the two steel plate guide side plates 1223. At this time, the part of the stainless steel plate that needs to be trimmed is at the bottom of the two cutting parts 12113. Then, the electric push rod 114 is activated to push the semi-circular push block 1116 to move the lifting plate 1114 to the top. During the process of the lifting plate 1114 rising, the rotating arm 118 and the second rotating arm 1110 rotate around the columnar central rod 1111. At the same time, the slide plate 116 slides to the right on the slide rail 115, so that the entire lifting structure stably lifts the lifting plate 1114 upward. As the lifting plate 1114 rises, the stainless steel plate also rises. At this time, when the lifting plate 1114 reaches the top... When the stainless steel plate of the part is attached to the bottom of the two cutting parts 12113, the electric push rod 114 continuously pushes the lifting plate 1114 to move to the top, thereby causing the Z-shaped rotating block 1216 with the concave hinge block 1219 as the axis to rotate under the push of the circular H-shaped sleeve block 1215. The spring 12111 is compressed, providing a buffer for the subsequent cutting process and avoiding excessive pressure on the stainless steel plate and damage. When the two sets of Z-shaped rotating blocks 1216 rotate, they drive the two sets of push-pull uprights 1224 to move downward and press the H-shaped plate 1115. The descent of the H-shaped plate 1115 will drive the two L-shaped lifting uprights 21 to descend synchronously. As the L-shaped lifting uprights 21 descend, the position of the horizontal hinge rod 22 will also move down, and the rotating rod 23 will rotate around the horizontal hinge rod 22. As the protective cover 24 moves downward, its outer wall slides along the trajectory of the arc-shaped guide plate 1226 because the outer wall of the protective cover guide block 25 is slidably connected to the inner side of the arc-shaped guide plate 1226. This continues until the cut piece 12113 and the stainless steel plate are covered. Then, the motor 121133 is started, driving the transmission disc 121134 to rotate. The power is transmitted to the foremost second transmission disc 121138 via the track 121135, and then the second track 121139 drives the other second transmission discs 121138 to rotate. This causes the columnar rotating block 121136 and the cutting wheel 121137 to rotate at high speed. The multiple cutting wheels 121137 are designed to decrease in size from front to back. The design, from front to back and from large to small, allows for progressively refined edge cutting according to the different cutting requirements of the stainless steel sheet. The larger cutting roller 121137 at the front performs a preliminary large-area cut on the edge of the stainless steel sheet, removing a large portion of the excess scrap material to prepare for subsequent fine cutting. The smaller cutting roller 121137 then further refines the edges after the preliminary cut, making the cut edges smoother and neater, ensuring the precision and quality of the cutting. Simultaneously, the second electric push rod 1212 is activated, pushing the convex push-pull plate 12112, causing the two cutting parts 12113 to move back and forth to perform the edge cutting operation on the stainless steel sheet. Due to the size differences and high-speed rotation of the multiple cutting rollers 121137,The forward and backward movement allows for more efficient edge trimming, further improving trimming quality and efficiency. Furthermore, the reciprocating motion of the convex push-pull plate 12112 is precisely synchronized with the rotational speed of the cutting wheel 121137, preventing edge burrs or skipping caused by phase misalignment.
