Description

Technical Field

[0001] This application relates to the field of stainless steel sheet production, and more specifically, to a cutting device with a feeding structure for stainless steel sheet production. Background Technology

[0002] Stainless steel sheets have high strength and hardness, and are usually cut using laser cutting machines. However, in actual operation, current laser cutting technology typically uses manual feeding to place the stainless steel sheets at the feeding point in the processing area of ​​the laser cutting machine, resulting in low feeding efficiency. Furthermore, general automatic feeding mechanisms are prone to workpiece displacement during the feeding process, affecting feeding stability. In addition, the feeding mechanism is limited by the environment and it is difficult to adapt and adjust the orientation angle accordingly.

[0003] Chinese patent application CN202320798110.1 discloses an automatic feeding device for laser cutting stainless steel sheets, including a support plate, a lifting platform mounted on the support plate, a limiting seat at the top of the support plate, a moving plate inserted laterally inside the limiting seat, and a pull rod hinged to the lower side of the lifting platform via a hinge block. This device can quickly fix sheet metal workpieces of different thicknesses. When clamping sheets of different widths, the relative distance between the two sets of moving plates can be manually adjusted, thereby adjusting the spacing between the two sets of pressure plates. The angle of the support plate can also be adjusted to meet the requirements of parallel or vertical feeding.

[0004] The above solution also has the following shortcomings: During production, the stainless steel plate is placed directly on the top of the lifting platform, which makes it difficult to correct. This causes the stainless steel plate to shift when it is fixed, which affects the subsequent cutting effect and reduces the practicality of the device. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a cutting device with a feeding structure for stainless steel plate production, which aims to improve the problem that when stainless steel plates are placed directly on the top of the lifting platform during production, it is not easy to make corrections, causing the stainless steel plates to shift when fixed, thus affecting the subsequent cutting effect and reducing the practicality of the device.

[0006] This application provides a cutting device with a feeding structure for stainless steel plate production, including a feeding structure and a correction structure. The feeding structure includes a base plate, a limiting frame, a lifting assembly, and a feeding frame. The limiting frame is fixedly connected to each of the four corners of the base plate. The lifting assembly is disposed on one side of the base plate. The feeding frame is connected to the lifting assembly and slidably connected to the limiting frame. The correction structure includes a servo motor, four ball screw pairs, four gears, a screw-nut pair, and two fixing plates. The servo motor is installed on one side of the feeding frame. The ball screw pairs are fixedly connected to the output end of the servo motor. The four ball screw pairs are rotatably connected to the four sides of the feeding frame. Each of the four ball screw pairs is fixedly connected to one end of a gear, and the four gears mesh with each other. Each of the four ball screw pairs is threadedly connected to a screw-nut pair. Two fixing plates are fixedly connected to one side of the screw-nut pair, and the fixing plates are slidably connected to the feeding frame.

[0007] In one specific implementation, the lifting assembly includes an electric push rod and a mounting plate. The electric push rod is mounted on one side of the base plate, the mounting plate is fixedly connected to the feeding frame, and the mounting plate is fixedly connected to the movable end of the electric push rod.

[0008] In the above process, the electric push rod and mounting plate make it easy to lift the stainless steel plate for loading.

[0009] In one specific implementation, a clamping assembly is provided at the top of the limiting frame. The clamping assembly includes a horizontal plate, an adjusting screw, a limiting rod, an L-shaped sliding plate, springs, and a pressure plate. One side of the horizontal plate is fixedly connected to the top of the limiting frame.

The limiting rod is fixedly connected to the L-shaped sliding plate and slidably connected to the horizontal plate. The L-shaped sliding plate is slidably connected to the horizontal plate. Several springs are fixedly connected inside the L-shaped sliding plate. The pressure plate is fixedly connected to the springs and slidably connected to the L-shaped sliding plate.

[0010] In the above implementation process, the stainless steel plate can be easily pressed by the horizontal plate, adjusting screw, limiting rod, L-shaped sliding plate, spring and pressure plate, which improves the fixing effect.

[0011] In one specific implementation, a bearing is embedded on one side of the L-shaped slide plate, and one end of the adjusting screw is interference-fitted with the inner ring of the bearing.

[0012] In the above process, by adjusting the interference fit between one end of the screw and the inner ring of the bearing, it is easy to reduce wear and tear, and at the same time, it is easy to move the L-shaped slide plate and adjust the position that needs to be pressed.

[0013] In one specific implementation, an adjustment assembly is provided on one side of the fixed plate. The adjustment assembly includes a movable plate, screw holes, a clamping plate, and bolts. The movable plate is slidably connected to both fixed plates. A plurality of screw holes are evenly provided on one side of the movable plate. The bolts pass through the fixed plates and are threadedly connected to the screw holes to fix the movable plate to the fixed plate. The clamping plate is fixedly connected to the movable plate.

[0014] In the above implementation process, the positions of the four movable plates can be easily adjusted by setting up movable plates, screw holes, clamping plates and bolts, which can easily adapt to stainless steel plates of different sizes.

[0015] In one specific implementation, a slide rod is fixedly connected inside the feeding frame, and the lead screw and nut pair is slidably connected to the slide rod.

[0016] In the above implementation process, the movement of the lead screw and nut pair can be conveniently limited by the sliding connection between the lead screw and nut pair and the slide rod.

[0017] In one specific implementation, the feeding frame has a through slot, and the fixing plate is slidably connected to the slot.

[0018] In the above implementation process, the movement of the fixed plate can be easily limited by the sliding connection between the fixed plate and the slot.

Detailed Implementation

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] Please see Figure 1 This application provides a cutting device with a feeding structure for stainless steel plate production, including a feeding structure 10 and a correction structure 20.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The feeding structure 10 includes a base plate 110, a limiting frame 120, a lifting component 130, and a feeding frame 140. The limiting frames 120 are fixedly connected to the four corners of the base plate 110. The lifting component 130 is located on one side of the base plate 110. The feeding frame 140 is connected to the lifting component 130 and is slidably connected to the limiting frame 120.

[0029] In a specific configuration, the lifting assembly 130 includes an electric push rod 131 and a mounting plate 132. The electric push rod 131 is installed on one side of the base plate 110, and the mounting plate 132 is fixedly connected to the feeding frame 140. The mounting plate 132 is also fixedly connected to the movable end of the electric push rod 131. The electric push rod 131 and the mounting plate 132 facilitate the lifting of the stainless steel plate for feeding.

[0030] In a specific configuration, a clamping assembly 150 is provided at the top of the limiting frame 120. The clamping assembly 150 includes a horizontal plate 151, an adjusting screw 152, a limiting rod 153, an L-shaped sliding plate 154, a spring 155, and a pressure plate 156. One side of the horizontal plate 151 is fixedly connected to the top of the limiting frame 120. The adjusting screw 152 is threadedly connected to the horizontal plate 151 and rotatably connected to the L-shaped sliding plate 154. The limiting rod 153 is fixedly connected to the L-shaped sliding plate 154. 153 is slidably connected to the horizontal plate 151, and the L-shaped slide plate 154 is slidably connected to the horizontal plate 151. Several springs 155 are fixedly connected inside the L-shaped slide plate 154. The pressure plate 156 is fixedly connected to the springs 155 and slidably connected to the L-shaped slide plate 154. The combination of the horizontal plate 151, adjusting screw 152, limiting rod 153, L-shaped slide plate 154, springs 155 and pressure plate 156 can easily press the stainless steel plate and improve the fixing effect.

[0031] In the specific setup, a bearing is embedded on one side of the L-shaped slide plate 154, and one end of the adjusting screw 152 is interference-fitted with the inner ring of the bearing. By adjusting the screw 152 with the inner ring of the bearing, wear can be easily reduced, and the L-shaped slide plate 154 can be easily moved to adjust the position that needs to be pressed.

[0032] In a specific configuration, a slide rod 160 is fixedly connected inside the feeding frame 140, and a lead screw and nut pair 240 is slidably connected to the slide rod 160. The slidable connection between the lead screw and nut pair 240 and the slide rod 160 facilitates the limitation of the movement of the lead screw and nut pair 240.

[0033] In a specific configuration, the feeding frame 140 has a through slot 170, and the fixing plate 250 is slidably connected to the slot 170. The slidable connection between the fixing plate 250 and the slot 170 allows for easy limitation of the movement of the fixing plate 250.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The correction structure 20 includes a servo motor 210, four ball screw pairs 220, four gears 230, a screw nut pair 240, and two fixing plates 250. The servo motor 210 is installed on one side of the feeding frame 140. The ball screw pairs 220 are fixedly connected to the output end of the servo motor 210. The four ball screw pairs 220 are rotatably connected to the four sides of the feeding frame 140 respectively. A gear 230 is fixedly connected to one end of each of the four ball screw pairs 220. The four gears 230 mesh with each other. Each of the four ball screw pairs 220 is threadedly connected to a screw nut pair 240. Two fixing plates 250 are fixedly connected to one side of the screw nut pair 240. The fixing plates 250 are slidably connected to the feeding frame 140.

[0035] In a specific configuration, an adjustment assembly 260 is provided on one side of the fixed plate 250. The adjustment assembly 260 includes a movable plate 261, screw holes 262, clamping plate 263, and bolts 264. Movable plates 261 are slidably connected to both fixed plates 250. Several screw holes 262 are evenly provided on one side of the movable plate 261. Bolts 264 pass through the fixed plate 250 and are threadedly connected to the screw holes 262 to fix the movable plate 261 to the fixed plate 250. The clamping plate 263 is fixedly connected to the movable plate 261. The movable plate 261, screw holes 262, clamping plate 263, and bolts 264 can be used to easily adjust the position of the four movable plates 261 to accommodate stainless steel plates of different sizes.

[0036] The working principle of this cutting device with a feeding structure for stainless steel plate production is as follows: When using the cutting device with a feeding structure for stainless steel plate production, according to the size of the stainless steel plate to be processed, by rotating the removed bolt 264, the sliding plate 261 along the fixed plate 250 is moved so that the spacing between the two sets of clamping plates 263 is adapted to the length and width of the stainless steel plate. After tightening the bolt 264, the stainless steel plate is placed on one side of the feeding frame 140. The ball screw pair 220 is driven to rotate by the servo motor 210. The four sets of screw nut pairs 240 are moved synchronously through the meshing gears 230, which drive the fixed plate 250 and its clamping plates. Plate 263 corrects and fixes the position of the stainless steel plate to prevent displacement during subsequent laser cutting, thus improving processing quality. The electric push rod 131 drives the mounting plate 132, which in turn drives the feeding frame 140 to rise vertically along the limiting frame 120 to complete the feeding. When the top of the stainless steel plate contacts the pressure plate 156, the pressure plate 156 is pushed by the plate and moves upward along the L-shaped slide plate 154, compressing the spring 155. The reaction force of the spring 155 makes the pressure plate 156 continuously press the surface of the stainless steel plate. By rotating the adjusting screw 152, the L-shaped slide plate 154 moves within the horizontal plate 151, which can easily adjust the position that needs to be pressed.

[0037] It should be noted that the specific models and specifications of the electric actuator 131 and the servo motor 210 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0038] The power supply and operating principle of the electric actuator 131 and the servo motor 210 are clear to those skilled in the art and will not be described in detail here.

[0039] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
