Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet processing equipment, and in particular to a metal sheet pressing and feeding device. Background Technology

[0002] In modern metal processing and manufacturing, automated feeding of metal sheets is a fundamental step in subsequent precision processing steps such as stamping, shearing, and bending. The performance of the feeding device directly determines the efficiency and product quality of the entire production line. Currently, feeding devices typically use roller friction drive to transport the sheet to the designated position.

[0003] However, in actual production, the metal sheets to be processed often have different widths and thicknesses. When adapting to such diverse production needs, the existing feeding devices have gradually revealed their structural limitations. On the one hand, for the positioning of the sheet width, many devices rely on manually adjusting the fixed guide baffles on both sides. This method is not only cumbersome and time-consuming, but also makes it difficult to ensure the absolute symmetry of the two baffles relative to the conveying center line. This will cause the sheet to deviate during the conveying process due to the inaccurate positioning reference, which in turn affects the processing accuracy of subsequent processes.

[0004] On the other hand, regarding the adaptation to sheet thickness, most existing clamping mechanisms adopt fixed gap or spring loading methods. Fixed gap methods cannot be compatible with sheets of different thicknesses, while simple spring loading, although it has a certain self-adaptive capability, provides unstable clamping force that is difficult to control precisely. When the clamping force is insufficient, the sheet will slip during high-speed feeding, resulting in inaccurate feeding step distance. When the clamping force is too large, it will cause indentations or scratches on the surface of softer metal sheets. In addition, during frequent adjustments and high-load operation, the large friction between the sliding parts of these adjustment mechanisms also exacerbates mechanical wear, reducing the smoothness of adjustment and the long-term reliability of positioning.

[0005] Therefore, this utility model proposes a metal sheet pressing and feeding device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the metal sheet pressing and feeding device, such as difficulty in achieving fast and accurate center positioning for sheets of different widths, poor adaptability to pressing sheets of different thicknesses, and large frictional resistance during adjustment and conveying, this utility model aims to provide a metal sheet pressing and feeding device with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, this utility model provides a metal sheet pressing and feeding device, comprising: a machine tool, a support bracket, a feeding roller, a pressing mechanism, and a limiting mechanism.

[0008] The limiting mechanism includes a screw, a gear, two toothed plates and a limiting wheel, and the pressing mechanism includes a cylinder, a sliding shaft and a pressing roller.

[0009] Furthermore, the screw of the limiting mechanism is threadedly connected to the bracket and is driven by gears meshing with two toothed plates to synchronously drive the two limiting wheels for symmetrical lateral adjustment; the pressing mechanism is located above the feeding roller, and its cylinder drives the sliding shaft and pressing roller for vertical position adjustment.

[0010] Preferably, the limiting wheel is rotatably mounted on the toothed plate via a rotating shaft, and is used to roll when in contact with the metal sheet to reduce friction.

[0011] Preferably, the limiting mechanism further includes a support frame, and the two toothed plates are slidably disposed within the support frame.

[0012] Preferably, the bottom of the screw engages with the inner wall of the gear, so that the screw can slide up and down on the inner wall of the gear while driving the gear to rotate synchronously.

[0013] Preferably, the clamping mechanism further includes a bracket and a connecting seat, the output end of the cylinder passes through the bracket and is fixedly connected to the top of the connecting seat, and the connecting seat is fixed to the sliding shaft.

[0014] Preferably, the clamping mechanism further includes a smoothing component disposed between the sliding shaft and the bracket to reduce sliding resistance.

[0015] Preferably, as a specific embodiment, the smoothing component includes a roller disposed on the side wall of the sliding shaft and a groove formed in the inner wall of the bracket, wherein the roller rolls in the groove.

[0016] Preferably, the outer periphery of the feeding roller is covered with a rubber layer to increase the feeding friction.

[0017] Preferably, the metal sheet pressing and feeding device further includes a driving component, which includes a servo motor and a rubber ring, and the servo motor drives the feeding roller to rotate through the rubber ring.

[0018] Preferably, the machine tool's discharge end is also provided with a ramp for guiding the metal sheet out.

[0019] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art of making it difficult to quickly and accurately center-position metal plates of different widths and the complex adjustment process by setting a limiting mechanism driven by a single screw and transmitted through gears and toothed plates to achieve synchronous and symmetrical adjustment of two limiting wheels. It achieves the technical effect of conveniently and quickly completing center limiting by operating only a single component, with accurate positioning and stable structure.

[0020] 2. This utility model solves the problem that the feeding device in the prior art is difficult to adapt to plates of different thicknesses and has a narrow range of applications by setting a pressing mechanism that is driven by a cylinder to move the sliding shaft up and down to adjust the height of the pressure roller. It achieves the technical effect of being able to quickly adapt to metal plates of different thicknesses, with a high degree of automation and strong applicability.

[0021] 3. This utility model solves the problems of uneven operation, easy wear, and even damage to the sheet material surface caused by large sliding friction during sheet material conveying and mechanism adjustment in the prior art by setting a rotatable limiting wheel at the lateral limiting point of the sheet material and setting a smooth component composed of rollers and wheel grooves in the up and down adjustment structure of the pressing mechanism. It achieves the technical effect of transforming sliding friction into rolling friction, significantly reducing running resistance, making the feeding process more stable and the adjustment smoother, and effectively protecting the sheet material.

[0025] Example: Please refer to Figures 1 to 5 This utility model provides a metal sheet pressing and feeding device, which aims to solve the problem in the prior art that it is difficult to achieve precise center positioning and adaptive pressing and feeding for metal sheets of different specifications at the same time.

[0026] like Figure 1 and Figure 2 As shown, a metal sheet pressing and feeding device includes a machine tool 1 serving as the mounting base for the entire device. The machine tool 1 is equipped with a support 3, multiple feeding rollers 201, a pressing mechanism 2, and a limiting mechanism 4. The multiple feeding rollers 201 are used to convey metal sheets, the limiting mechanism 4 is used to laterally limit the metal sheets to achieve center positioning, the pressing mechanism 2 is located above the feeding rollers 201 and is used to press the metal sheets, while the support 3 is used to support the limiting mechanism 4.

[0027] To resolve the aforementioned technical issues, please refer to the following: Figure 3 , Figure 4 and Figure 5The core of the technical solution in this embodiment lies in the fact that the device achieves adaptive adjustment of the width and thickness of the metal sheet through the structural cooperation of the limiting mechanism 4 and the pressing mechanism 2. The limiting mechanism 4 includes a screw 405 threadedly connected to the bracket 2 3. The bottom of the screw 405 engages with the inner wall of the gear 406. The gear 406 meshes with two toothed plates 401. The two toothed plates 401 are slidably connected to the support frame 404 fixed inside the bracket 2 3. A rotating shaft 402 is fixedly connected to each toothed plate 401. The limiting wheel 403 is rotatably connected to the rotating shaft 402. Through the symmetrical transmission structure of the screw 405-gear 406-toothed plate 401, the synchronous movement of the two limiting wheels 403 towards each other or towards each other is achieved. The pressing mechanism 2 includes a bracket 204 fixed on the machine tool 1, a cylinder body of a cylinder 205 fixedly connected to the bracket 204, an output end of the cylinder 205 fixedly connected to the top of a connecting seat 208, a connecting seat 208 fixedly connected to a sliding shaft 206, a sliding shaft 206 slidably connected to the inner wall of the bracket 204, and a pressure roller 207 rotatably connected to the sliding shaft 206. Through the linear motion structure driven by the cylinder 205, the high and low positions of the pressure roller 207 are adjusted. The drive assembly 203 that provides power to the feeding roller 201 consists of a servo motor 2031 and a rubber ring 2032. Its specific internal structure is well-known in the art and will not be described in detail here.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In one preferred embodiment, to increase the friction between the feed roller 201 and the metal plate and prevent slippage, the outer periphery of the feed roller 201 is covered with a rubber layer 202; in another preferred embodiment, to reduce the friction when the sliding shaft 206 moves up and down, please refer to... Figure 5 The clamping mechanism 2 also includes a smoothing component 209 disposed between the slide shaft 206 and the bracket 204. The smoothing component 209 includes a roller 2091 disposed on the side wall of the slide shaft 206 and a wheel groove 2092 opened on the inner wall of the bracket 204. The roller 2091 rolls in the wheel groove 2092, converting sliding friction into rolling friction. As another preferred embodiment, in order to provide stable and controllable power to the feeding roller 201, the device also includes a drive component 203. The drive component 203 includes a servo motor 2031 and a leather ring 2032. The servo motor 2031 is connected to multiple feeding rollers 201 through the leather ring 2032. As another preferred embodiment, in order to facilitate the export of the processed metal sheet, a ramp 5 is fixedly connected to the discharge end of the machine tool 1.

[0029] Working Principle: Before operation, place the metal plate on the rubber layer 202 under the support 2 3. Adjust the limiting mechanism 4 to limit the metal plate. Rotate the screw 405 clockwise. The screw 405 is threadedly connected to the inner wall of the support 2 3. According to the principle of thread transmission, the screw 405 moves downward while rotating, and its bottom engages with the inner wall of the gear 406. The screw 405 drives the gear 406 to rotate synchronously while sliding up and down on the inner wall of the gear 406. The gear 406 is between the two toothed plates 401 and meshes with them. When the gear 406 rotates clockwise, it pushes the two toothed plates 401 to slide towards each other in the support frame 404. The rotating shaft 402 and the limiting wheel 403 on the toothed plates 401 move towards the central axis of the machine tool 1 synchronously until the two limiting wheels 403 are in contact with the metal plate. Stop rotating the screw 405. According to the principle of thread self-locking, the screw 405 is locked. Within the bracket 2 3, the entire limiting mechanism 4 completes the limiting of the metal plate, restricting the metal plate to the middle of the machine tool 1 to prevent position deviation during feeding. After adjusting the distance between the two limiting wheels 403, the device is started. At this time, the drive component 203 provides power for the transport of the machine tool 1. The servo motor 2031 rotates, driving the rubber ring 2032 to rotate, thereby driving multiple feeding rollers 201 to rotate. The rubber layer 202 on the feeding rollers 201 increases the friction between the metal plate and prevents the metal plate from slipping. Under the rotation of multiple feeding rollers 201, the static friction drives the metal plate to move backward. During the movement, the metal plate first passes through the limiting mechanism 4. The left and right sides of the metal plate are connected to the two limiting wheels 403. The limiting wheels 403 restrict the metal plate to the middle of the machine tool 1. At the same time, the limiting wheels 403 rotate around the rotating shaft 402 to reduce the friction between the metal plate and the metal plate. After the metal plate reaches the bottom of the pressure roller 207, the pressure roller 207 contacts the top of the metal plate. The pressure roller 207, like the surface of the rubber layer 202, is elastic and exerts pressure on the metal plate. During the movement of the metal plate, the pressure roller 207 rotates on the outer wall of the sliding shaft 206. When conveying metal plates of different specifications, the distance between the limit wheels 403 is adjusted by rotating the screw 405 to accommodate the width of the metal plate. The extension and retraction of the cylinder 205 is controlled to accommodate the height of the metal plate. The output end of the cylinder 205 passes through the bracket 204 and is fixedly connected to the top of the connecting seat 208. When the cylinder 205 extends or retracts, it drives the connecting seat 208 to move up and down. The receiving seat 208 drives the sliding shaft 206 to slide up and down on the inner wall of the bracket 204. During this process, the smoothing component 209 reduces the friction between the sliding shaft 206 and the bracket 204. Rollers 2091 are provided on the left and right sides and the front and rear sides of the sliding shaft 206. The rollers 2091 rotate on the inner wall of the sliding shaft 206 and roll in the wheel groove 2092, converting sliding friction into rolling friction. The up and down movement of the sliding shaft 206 changes the distance between the bottom of the pressure roller 207 and the top of the rubber layer 202, thereby adapting to metal plates of different thicknesses. After the metal plate is pressed and transmitted by the pressing mechanism 2 and the center limit of the limiting mechanism 4, it is transmitted to the next processing step by the slide 5.
