Description

Technical Field

[0001] This utility model relates to the technical field of uncoiling, leveling and feeding machines, specifically an expansion and contraction mechanism for an uncoiling, leveling and feeding machine. Background Technology

[0002] The uncoiling, leveling, and feeding machine is an automated device that integrates three functions: uncoiling, leveling, and feeding. It is commonly used in automated stamping production. It can automatically unwind (uncoil) coiled metal materials, then level them through the leveling section, and finally accurately feed the material into the stamping press for stamping. The whole process is highly automated and does not require manual guidance, thus improving production efficiency.

[0003] The aforementioned technologies have certain shortcomings in their application: when feeding rolled metal materials into the punch press, due to the different actual widths of the metal materials, in order to ensure that the center line of the roll material is basically aligned with that of the leveling feeder, an expansion and contraction mechanism is needed to limit the roll material and prevent the material from deviating.

[0004] To address these issues, this invention provides an expansion and contraction mechanism for an uncoiling, leveling, and feeding machine. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an expansion and contraction mechanism for an uncoiling, leveling, and feeding machine, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an expansion and contraction mechanism for an uncoiling and leveling feeding machine, including a base, with fixed seats symmetrically fixedly installed on the front and rear parts of the top wall of the base, and the same expansion and contraction component installed on the adjacent side of the two fixed seats, with guide components fixedly installed on the top wall of the expansion and contraction component.

[0007] The expansion and contraction assembly includes a servo motor, which is fixedly connected to the outer wall of the rear fixed base. The same bidirectional lead screw is rotatably mounted on the adjacent side of the two fixed bases, and the same positioning rod is mounted on the adjacent side of the two fixed bases. Slider blocks are screwed onto the front and rear parts of the outer wall of the bidirectional lead screw. Support blocks are fixedly mounted on the outer walls of the two sliders. Several diagonal braces are fixedly mounted on the bottom walls of several support blocks. Several diagonal braces are fixedly connected to the corresponding outer walls of the sliders. Connecting plates are fixedly mounted on the top walls of the two sliders. A segmented telescopic protective sleeve is installed on the outer wall of the bidirectional lead screw.

[0008] Through the above technical solution, the setting of the expansion and contraction components can quickly adjust the spacing of the guide components and adapt to metal rolls of different widths.

[0009] Furthermore, the power shaft of the servo motor passes through the corresponding fixed seat and is fixedly connected to the rear end of the bidirectional lead screw via a bearing. The inner walls of the bottom of the two sliders are slidably connected to the outer wall of the positioning rod. The two support blocks on the same slider are arranged symmetrically from left to right, and several support blocks are all horizontal with the top wall of the corresponding slider.

[0010] Through the above technical solution, the servo motor is mainly used to drive the bidirectional lead screw to rotate, thereby causing the slider to slide along the outer wall of the bidirectional lead screw and the positioning rod.

[0011] Furthermore, the bottom walls of both connecting plates are fixedly connected to the top walls of the corresponding support blocks, the top walls of both connecting plates are fixedly connected to the bottom walls of the corresponding guide components, and the segmented telescopic protective sleeves are fixedly connected to the corresponding fixed seats and sliders.

[0012] The segmented telescopic protective sleeve provided by the above technical solution is mainly to protect the outer wall of the bidirectional lead screw and prevent debris from the surface of the metal coil from falling onto the outer wall of the bidirectional lead screw and affecting the normal movement of the slider.

[0013] Furthermore, the guiding assembly includes two guide frames, which are arranged symmetrically front to back, and the bottom walls of both guide frames are fixedly connected to the top wall of the connecting plate.

[0014] With the above technical solution, the connecting plate will drive the guide frame to move when it moves, and the metal coil can be transported through the guide frame.

[0015] Furthermore, guide grooves are provided on the adjacent sides of the two guide frames, and anti-scratch pads are fixedly installed in the middle of the inner wall of the two guide grooves.

[0016] The above technical solution mainly protects the edges of the metal roll material from scratches and deformation.

[0017] Furthermore, several rotating shafts are uniformly installed on the inner walls of the two guide grooves, and transmission rollers are fixedly installed on the outer walls of the rotating shafts. The transmission rollers are arranged symmetrically one above the other.

[0018] Through the above technical solution, the interaction between the drive roller and the rotating shaft provides an auxiliary conveying function for the metal coil.

[0019] Furthermore, mounting ears are fixedly installed at the four corners of the outer wall of the base, and mounting holes are opened on the top wall of several mounting ears.

[0020] Using the above technical solution, the entire device is installed at the discharge port of the uncoiling and leveling feeder by passing external bolts through the mounting holes on the mounting ears.

[0030] 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.

[0031] Example 1:

[0032] Please see Figures 1-5 An expansion and contraction mechanism for an uncoiling leveling feeder includes a base 1. Fixed seats 5 are symmetrically fixedly installed on the front and rear parts of the top wall of the base 1. The same expansion and contraction component 4 is installed on the adjacent side of the two fixed seats 5. Guide components 6 are fixedly installed on the top wall of the expansion and contraction component 4.

[0033] The expansion / contraction assembly 4 includes a servo motor 42, which is fixedly connected to the outer wall of the rear-mounted base 5. A single bidirectional lead screw 41 is rotatably mounted on adjacent sides of both bases 5. A single positioning rod 43 is mounted on adjacent sides of both bases 5. Slider blocks 44 are screwed onto the front and rear parts of the outer wall of the bidirectional lead screw 41. Support blocks 45 are fixedly mounted on the outer walls of both sliders 44. Several diagonal braces 46 are fixedly mounted on the bottom walls of several support blocks 45. Each diagonal brace 46 is fixedly connected to the corresponding outer wall of the slider 44. Connecting plates 48 are fixedly mounted on the top walls of both sliders 44. A segmented telescopic protective sleeve 47 is installed on the outer wall of the rod 41. The power shaft passes through the corresponding fixed seat 5 and is fixedly connected to the rear end of the double-acting screw 41 via a bearing. The bottom inner walls of the two sliders 44 are slidably connected to the outer wall of the positioning rod 43. Two support blocks 45 located on the same slider 44 are arranged symmetrically on the left and right. Several support blocks 45 are horizontal to the top wall of the corresponding slider 44. The bottom walls of the two connecting plates 48 are fixedly connected to the top walls of the corresponding support blocks 45. The top walls of the two connecting plates 48 are fixedly connected to the bottom walls of the corresponding guide components 6. The segmented telescopic protective sleeve 47 is fixedly connected to the corresponding fixed seat 5 and slider 44.

[0034] In this embodiment of the utility model, the purpose of this arrangement is that the expansion and contraction component 4, by adjusting the rotation of the bidirectional lead screw 41, drives the sliders 44 to move away from or closer to each other, thereby adjusting the spacing of the guide component 6, which can be adapted to metal coils of different widths. With the cooperation of the support block 45 and the diagonal brace 46, it provides support for the guide component 6.

[0035] Example 2:

[0036] Please see Figures 1-5 This embodiment provides a technical solution based on embodiment one: the guide component 6 includes two guide frames 61, which are arranged symmetrically front and back. The bottom walls of the two guide frames 61 are fixedly connected to the top wall of the connecting plate 48. A guide groove 65 is opened on the adjacent side of the two guide frames 61. A scratch-resistant pad 64 is fixedly installed in the middle of the inner wall of the two guide grooves 65. A number of rotating shafts 63 are evenly rotatably installed on the inner wall of the two guide grooves 65. A transmission roller 62 is fixedly installed on the outer wall of the number of rotating shafts 63. The number of transmission rollers 62 are arranged symmetrically one to one from top to bottom. Mounting ears 2 are fixedly installed at the four corners of the outer wall of the base 1. Mounting holes 3 are opened on the top wall of the number of mounting ears 2.

[0037] In this embodiment of the present invention, the purpose of this arrangement is that, when the metal coil passes through the rotating shaft 63 and the transmission roller 62, the transmission roller 62 rotates synchronously under the driving force of the coil movement, thus playing an auxiliary role in conveying the metal coil.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] The working principle of this device is as follows: First, with the cooperation of the base 1 and the mounting ear 2, the entire device is installed at the feeding outlet of the uncoiling and leveling feeder. Then, the spacing between the guide components 6 is adjusted according to the width of the metal coil. The servo motor 42 drives the bidirectional lead screw 41 to rotate. When the bidirectional lead screw 41 rotates, it drives the slider 44 to slide away from or towards each other along the outer wall of the bidirectional lead screw 41 and the positioning rod 43. When the slider 44 moves, it drives the segmented telescopic protective sleeve 47 to extend and retract, preventing metal debris on the metal coil from falling onto the outer wall of the bidirectional lead screw 41 and affecting the normal movement of the slider 44. When the slider 44 moves, it drives the corresponding support block 45 and the diagonal brace 46 to move synchronously. When the slider 44 moves, it drives the corresponding support block 45 and the diagonal brace 46 to move, so that the connecting plate 48 moves synchronously.

[0040] When the connecting plate 48 moves, it drives the guide frame 61, the transmission roller 62 and the rotating shaft 63 to the appropriate position. After the metal coil passes through the guide frame 61 and the guide groove 65, the coil passes through the position between the transmission roller 62 and the rotating shaft 63 at the same time, and the edge of the coil contacts the anti-scratch pad 64 to prevent scratching.

[0041] The entire device, through the expansion and contraction adjustment of the expansion and contraction component 4 and the guide component 6, can adapt and adjust to metal coils of different widths, so that the entire metal coil can be smoothly conveyed for production. After passing through the guide frame 61 and the rotating shaft 63, the metal coil is driven by the coil and rotates along the direction of the coil's movement, which has an auxiliary conveying function for the metal coil.
