Description

Technical Field

[0001] This utility model relates to the field of steel strip processing technology, specifically a bidirectional reversible steel strip trimming machine. Background Technology

[0002] Currently, most existing steel strip trimming and deburring devices can only perform one-time unidirectional winding and unwinding trimming, which is not convenient for repeated trimming in both directions. Often, the trimming and deburring are not thorough, the trimming effect is poor, and the edges of the trimmed steel strip are often not smooth and neat. When using steel strip, it is easy to scratch the hands of workers and other related equipment, tools and materials, which cannot meet the needs of production and processing. Therefore, a bidirectional reversible steel strip trimming machine is proposed. Utility Model Content

[0016] 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.

[0017] Please see Figure 1-6This utility model provides a technical solution: a bidirectional reversible steel strip trimming machine, including a trimming table 1. A slag discharge trough 11, communicating with its inner cavity, is provided in the middle of the upper surface of the trimming table 1 for slag discharge during trimming. A slag outlet 12, communicating with its inner cavity, is provided on the front side of the trimming table 1 for cleaning and slag removal after trimming. Mounting frames 2 are symmetrically welded and fixed (or fixed by bolts and nuts) on the left and right sides of the trimming table 1. Rotating shafts 3 are rotatably connected to the two mounting frames 2 respectively, and the front ends of the two rotating shafts 3 are respectively welded... A steel strip reel 4 is fixed (or secured by bolts and nuts) for winding and unwinding the steel strip. Two rotating shafts 3 are respectively equipped with synchronous rotation drive components 5 capable of bidirectional forward and reverse rotation at their rear ends. Limiting and guiding components 6 for limiting and guiding the steel strip are symmetrically arranged on the upper surface of the trimming table 1 on the left and right sides of the slag discharge trough 11. Lifting and telescopic adjustment components 7 are symmetrically arranged on the upper surface of the trimming table 1 on the front and rear sides of the slag discharge trough 11. Tool holders 8 are symmetrically arranged on the inner ends of the two lifting and telescopic adjustment components 7. Blade 1 9 is symmetrically welded and fixed (or fixed by bolts and nuts) on the upper inner side of the two blade holders 8. Blade 2 10 is symmetrically welded and fixed (or fixed by bolts and nuts) on the lower inner side of the two blade holders 8, with the direction opposite to that of blade 1 9. In use, the steel strip to be trimmed is wound around the steel strip reel 4. The lifting and telescopic adjustment component 7 is used to align the steel strip to be trimmed, which has passed through the two limit guide components 6 in sequence, with the two blades 1 9. The synchronous rotation drive component 5 is rotated in the forward direction, which drives the two steel strip reels 4 to rotate in the forward direction for trimming. Then, the lifting and telescopic adjustment component 7 is used to align the steel strip after trimming with the two blades 2 10. The synchronous rotation drive component 5 is rotated in the reverse direction, which drives the two steel strip reels 4 to rotate in the reverse direction for trimming. The above operation is repeated to trim the steel strip repeatedly in both directions. The trimming and deburring are relatively thorough, and the trimming effect is good. The edge of the trimmed steel strip is smooth and neat. When using the steel strip, it will not scratch the hands of the workers or other related equipment, tools and materials.

[0018] Furthermore, such as Figure 4As shown, the synchronous rotation drive assembly 5 includes a synchronous pulley 51, a synchronous belt 52, a driven shaft 53, a driven gear 54, a drive motor 55, a drive shaft 56, and a drive gear 57. The rear ends of the two rotating shafts 3 are respectively welded to (or fixed with bolts and nuts) with synchronous pulleys 51. Synchronous belts 52 are fitted onto the two synchronous pulleys 51. The rear end of one of the synchronous pulleys 51 is welded to (or fixed with bolts and nuts) with a driven shaft 53. The rear end of the driven shaft 53 is welded to (or fixed with bolts and nuts) with a driven gear 54. The rear side of the trimming table 1 is fixed with a drive motor 55 via bolts and nuts. The output shaft of the drive motor 55 is connected to the drive shaft 56. The front end of the drive shaft 56 is welded and fixed (or fixed with bolts and nuts), and the rear end of the drive shaft 56 is welded and fixed (or fixed with bolts and nuts) with a drive gear 57. The drive gear 57 meshes with the driven gear 54. In use, the drive motor 55 drives the drive shaft 56 and the drive gear 57 to rotate, which in turn drives the driven gear 54 and the driven shaft 53 to rotate, which in turn drives the two synchronous pulleys 51 to rotate synchronously. Furthermore, the forward and reverse rotation of the drive motor 55 drives the two synchronous pulleys 51 to rotate synchronously in both directions, which in turn drives the two steel strip reels 4 to rotate synchronously in both directions, facilitating the forward and reverse winding and unwinding of the steel strip for repeated trimming.

[0019] Furthermore, such as Figure 5 As shown, the limiting and guiding assembly 6 includes a U-shaped bracket 61, a first guide roller 62, and a second guide roller 63. The U-shaped bracket 61 is welded and fixed (or fixed by bolts and nuts) to the upper surface of the trimming table 1. The first guide roller 62 and the second guide roller 63 are rotatably connected to the upper and lower parts of the inner sides of the two arms of the U-shaped bracket 61 by bearings, respectively. A gap is formed between the two first guide rollers 62 and the second guide roller 63, which allows the steel strip to pass through and be limited and guided. In use, by passing the steel strip through the limiting and guiding gap between the corresponding two sets of first guide rollers 62 and second guide roller 63 in sequence, the steel strip can be assisted in limiting and guiding, which is conducive to its better movement and trimming.

[0020] Furthermore, such as Figure 6As shown, the lifting and telescopic adjustment assembly 7 includes an electric lifting rod 71, a lifting block 72, and an electric telescopic rod 73. The electric lifting rod 71 is fixed to the upper surface of the trimming table 1 by bolts and nuts. The top of the electric lifting rod 71 is fixed to the lifting block 72 by bolts and nuts. The electric telescopic rod 73 is fixed to the inner side of the lifting block 72 by bolts and nuts. The inner end of the electric telescopic rod 73 is fixedly connected to the outer end of the blade holder 8 located on the same side by bolts and nuts. In use, the electric lifting rod 71 moves up and down, which drives the blade holder 8 to move up and down. The electric telescopic rod 73 moves inward and outward, which drives the blade holder 8 to move inward and outward, so that it moves closer to or away from the two sides of the steel strip. According to the needs of forward and reverse trimming, the two sets of corresponding blades 1 9 or blades 2 10 can be aligned with the two sides of the steel strip.

[0021] Specifically, the drive motor 55 is preferably a servo motor that can rotate in both directions, which is commonly used in the prior art. The electric lifting rod 71 and the electric telescopic rod 73 are both electric push rods commonly used in the prior art. The drive motor 55, the electric lifting rod 71 and the electric telescopic rod 73 are electrically connected to the external power supply and the control switch respectively. Their connection and operation control principles are all existing mature technologies, and their principles will not be further described here.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
