Description

Technical Field

[0001] This utility model relates to the field of sheet material processing technology, specifically a sheet material feeding device. Background Technology

[0002] Thin sheet materials are a general term for a class of materials that are relatively thin. They can be classified as metal sheets and non-metal sheets depending on the material, and are used in different industries.

[0003] When stamping thin sheet materials, the material needs to be fed intermittently. Since thin sheet materials are usually easy to roll up, the traditional method of feeding thin sheet materials during stamping is to roll up the material at one end. However, after stamping, the sheet is partially missing, and the material is easily deformed by the traction force during rolling, which affects the flatness of the unprocessed part. Utility Model Content

[0004] The purpose of this utility model is to provide a sheet material feeding device, which uses a lifting component to lower a movable top plate to clamp the material with a fixed bottom plate. Then, driven by a conveying component, the fixed bottom plate, the movable top plate, and the clamped unprocessed material portion move synchronously to one side. Finally, a winding component winds up the processed material segment, thus avoiding the deformation of the material after processing from affecting the unprocessed segment, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sheet material feeding device, comprising:

[0006] Workbench;

Detailed Implementation

[0025] 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.

[0026] This utility model provides, for example Figures 1-5 The sheet material feeding device shown includes:

[0027] Workbench 1;

[0028] Two sets of track frames 2 are fixedly installed on the top of the workbench 1. Two sets of fixed base plates 3 and movable top plates 4 are set on the opposite side of the track frames 2. A fixed frame 5 is fixed on the outside of the fixed base plate 3. A lifting component 6 is set in the inner cavity of the fixed frame 5 to drive the movable top plate 4 to move up and down to clamp the sheet material. A conveying component 7 is set in the inner cavity of the track frame 2 to move the fixed frame 5 left and right.

[0029] It also includes a winding assembly 8 for pulling the sheet material;

[0030] The worktable 1 has a through slot, and a lower stamping die 9 is movably arranged in the inner cavity of the through slot. An upper stamping die 10 is arranged above the lower stamping die 9. The upper stamping die 10 and the lower stamping die 9 are located above and below the sheet material, respectively. A drive assembly 11 is provided to move the upper stamping die 10 and the lower stamping die 9.

[0031] The edge of the sheet material is clamped by the fixed base plate 3 and the movable top plate 4, and then the unprocessed section of the material is conveyed to one end of the take-up roller 82 under the drive of the conveying component 7. This not only makes it convenient for the take-up roller 82 to take up the processed material section, but also avoids pulling the sheet material, which would cause the processed material to deform and interfere with the unprocessed section, thus ensuring the flatness of the stamped part.

[0032] The lifting assembly 6 includes a servo motor 61 mounted on the top of the fixed frame 5. The output shaft of the servo motor 61 passes through the fixed frame 5 and is fixed with a lifting screw 62. The bottom of the lifting screw 62 rotates to the top of the fixed base plate 3 via a bearing. The lifting screw 62 is threaded through the movable top plate 4. The servo motor 61 drives the lifting screw 62 to rotate, and then the lifting screw 62 drives the movable top plate 4 to move up and down within the fixed frame 5, which facilitates clamping and releasing of the sheet material in conjunction with the fixed base plate 3.

[0033] The conveying assembly 7 includes a translation screw 71 rotatably connected to the inner cavity of the track frame 2 via a bearing. The outer side of the fixing frame 5 extends into the inner cavity of the track frame 2 and is threadedly connected to the outer side of the translation screw 71. A drive motor 72 is fixed to the outer side of the track frame 2. The output shaft of the drive motor 72 passes through the inner cavity of the track frame 2 and is fixed with a first bevel gear 73. One end of the translation screw 71 is fixed with a second bevel gear 74 that meshes with the first bevel gear 73. The drive motor 72 serves as a power source, working in conjunction with the first bevel gear 73 and the second bevel gear 74 to drive the translation screw 71, causing the fixing frame 5 to move left and right within the track frame 2, facilitating the conveying of the clamped sheet material segment.

[0034] The winding assembly 8 includes a support plate 81 fixed to one end of the top of the workbench 1. A winding roller 82 is rotatably connected to the opposite side of the support plate 81 via a bearing. The sheet material is wound around the outside of the winding roller 82. A winding motor 83 is installed on the outside of a set of support plates 81. The output shaft of the winding motor 83 is fixedly connected to one end of the winding roller 82. The winding motor 83 drives the winding roller 82 to rotate, which facilitates the winding of the sheet material and at the same time tensions the sheet material, making the surface of the sheet material tend to be flat.

[0035] The drive assembly 11 includes a mounting bracket 111 fixed to the top and bottom of the worktable 1. A hydraulic cylinder 112 is mounted on the outside of the mounting bracket 111. The piston rod of the hydraulic cylinder 112 passes through the inside of the mounting bracket 111 and is fixedly connected to the upper stamping die 10 and the lower stamping die 9 respectively. The upper stamping die 10 and the lower stamping die 9 are moved towards each other by the hydraulic cylinder 112. The upper stamping die 10 and the lower stamping die 9 are stamped to process the sheet material in cooperation. At the same time, the upper stamping die 10 and the lower stamping die 9 are moved away from the sheet material to avoid interfering with the conveying of the sheet material.

[0036] To improve the stability of the movable top plate 4, a limit rod 12 is fixed to the top of the fixed base plate 3. The top of the limit rod 12 passes through the movable top plate 4 and is fixedly connected to the fixed frame 5.

[0037] A fixed frame 13 is fixed on the top of the workbench 1 away from the mounting plate. The inner cavity of the fixed frame 13 is rotatably connected to a limiting roller 14 for clamping the sheet material through a bearing. The setting of the limiting roller 14 facilitates the tensioning of the sheet material and avoids the sheet material from being too loose, which would cause the sheet material to fold or wrinkle.

[0038] In practical use, the sheet material is extended to the left between the two sets of limiting rollers 14, then wound around the take-up roller 82, and placed between the movable top plate 4 and the fixed bottom plate 3. The hydraulic cylinder 112 is activated, driving the upper stamping die 10 and the lower stamping die 9 to move towards the center to stamp the sheet material. After separation, the sheet material near the take-up roller 82 is stamped. Then, the servo motor 61 drives the lifting screw 62, causing the lifting screw 62 to move the movable top plate 4 downward within the fixed frame 5, using the movable top plate 4 and the fixed bottom plate 3 to clamp the sheet material. The first bevel gear 73 is driven by the drive motor 72 to rotate, and the first bevel gear 73 drives the translation screw 71 to rotate through the second bevel gear 74. The fixed frame 5 moves to the left under the drive of the translation screw 71. At the same time, the fixed base plate 3 and the movable top plate 4 drive the clamped sheet material to move to the left synchronously. Then the winding motor 83 drives the winding roller 82 to rotate and wind up the processed sheet material. Since the fixed base plate 3 and the movable top plate 4 clamp and protect the unprocessed section of the sheet material, the flatness of the section of sheet material can be guaranteed. Then the sheet material is processed and transported periodically.
