Description

Technical Field

[0001] This utility model relates to the field of steel strip cutting technology, and in particular to an SMT steel strip cutting fixture. Background Technology

[0002] Steel strip is a type of steel product widely used in many fields. It features high precision, good surface quality, and ease of processing. Its main uses include manufacturing damping leaf springs and coil springs for automobiles, tractors, and locomotives, cylinder safety valve springs, and steel leaf springs with medium and small cross sections, such as front and rear auxiliary leaf springs for automobiles.

[0003] However, in the existing technology, the connection between the winding wheel used for winding steel strip and the device body is not convenient for disassembly. Replacing the winding wheel and rearranging the steel strip is troublesome and time-consuming. At the same time, the steel strip has a certain degree of bending when it is pulled out from the winding wheel, which is inconvenient for cutting. Therefore, we propose an SMT steel strip cutting fixture. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-6 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0023] like Figure 1-6As shown, this utility model discloses an SMT steel strip cutting fixture, comprising a frame 1. Two symmetrically arranged support plates 2 are vertically fixedly mounted at one end of the frame 1. A winding wheel 3 is horizontally arranged between the two support plates 2. Limiting rings are fixedly sleeved on the shafts at both ends of the winding wheel 3 to prevent the winding wheel 3 from moving laterally while rotating. The shafts of the winding wheel 3 are rotatably connected to the support plates 2. A fixed frame 4 is fixedly mounted in the middle of the frame 1. An auxiliary roller 5 is horizontally rotatably mounted on the lower part of the fixed frame 4. A connecting frame 6 is mounted on the upper part of the fixed frame 4 through a lifting control mechanism. Multiple straightening rollers 7 are horizontally rotatably mounted on the connecting frame 6. The shafts of the multiple straightening rollers 7 are respectively fixedly mounted with first pulleys 8. Adjacent first pulleys 8 are indirectly connected through a first belt 9. A pulley 8 is connected to a power mechanism. A mounting frame 10 is fixedly installed at the end of the frame 1 away from the support plate 2. A first electric push rod 11 is vertically fixedly installed on the mounting frame 10. The free end of the first electric push rod 11 moves through the mounting frame 10. A cutting blade 12 is horizontally fixedly installed on the free end of the first electric push rod 11. The frame 1 is provided with a cutting groove 13 that corresponds to and fits the cutting blade 12. This device can splice the support plate 2 into an upper support 14 and a lower support 15. The upper support 14 and the lower support 15 are connected and fixed by a snap-fit ​​technique, which facilitates the replacement and installation of the winding wheel 3. At the same time, the height of the vertically adjustable straightening roller 7 is provided to facilitate the application to steel sheets of different thicknesses and to facilitate the setting of steel sheets, making it more versatile.

[0024] Specifically, the support plate 2 includes an upper support 14 and a lower support 15 that are in contact with each other. A connecting rod 16 that is movably embedded in the lower support 15 is vertically fixed on the lower end face of the upper support 14. An L-shaped auxiliary component 17 is fixedly installed on the outer wall of the lower support 15. Two plug-in rods 18 are movably inserted through the upper part of the auxiliary component 17. The plug-in rods 18 movably pass through the lower support 15 and are movably embedded in the connecting rods 16. The two plug-in rods 18 are fixedly connected by a transition rod 19. The transition rod 19 is fixedly connected to the auxiliary component 17 by a spring 20 that is movably sleeved on the outer wall of the plug-in rod 18. The upper support 14 and the lower support 15 are fixedly connected by components such as the connecting rod 16 and the plug-in rods 18, which can realize the quick installation and docking of the upper support 14 and the lower support 15, and facilitate the disassembly and replacement of the winding wheel 3 and the installation and arrangement of steel strip.

[0025] More specifically, the lifting control mechanism includes a second electric push rod 21 that is vertically fixedly installed on the upper part of the fixed frame 4. The free end of the second electric push rod 21 moves through the fixed frame 4 and is fixedly connected to the connecting frame 6. The second electric push rod 21 can indirectly drive the straightening roller 7 to move up and down to adjust the height, which is convenient for the arrangement of steel sheet materials. At the same time, it can be used for bonding and rolling with steel sheet materials of different thicknesses.

[0026] Furthermore, the power mechanism includes a motor 22 that is horizontally fixedly installed on the upper end face of the connecting frame 6. The output shaft of the motor 22 is fixedly installed with a second pulley 23. The second pulley 23 is connected to one of the first pulleys 8 through a second belt 24. The motor 22 indirectly drives multiple straightening rollers 7 to rotate through the transmission of components such as the second pulley 23 and the second belt 24, ensuring that the straightening rollers 7 rotate in the same direction and pull the steel sheet material to move.

[0027] Working principle:

[0028] The winding wheel 3 with the steel strip is mounted on the lower support 15. Then, the adapter rod 19 is pulled outward, causing the adapter rod 19 to overcome the force of the spring 20 and drive the insertion rod 18 outward. The insertion rod 18 is pulled out of the lower support 15. Then, the connecting rod 16 of the upper support 14 is inserted into the lower support 15 to complete the docking of the upper support 14 and the lower support 15. Then, the adapter rod 19 is released to allow the insertion rod 18 to return to its original position and be inserted into the lower support 15, completing the installation. Then, the end of the steel strip is passed between the straightening roller 7 and the auxiliary roller 5 and under the cutting blade 12. Then, the second electric push rod 21 is controlled. The connecting frame 6 moves downward, and the straightening roller 7 moves downward synchronously with the connecting frame 6, so that the straightening roller 6 comes into contact with the steel strip. Then, the motor 22 is controlled, and the motor 22 drives the second pulley 23 to rotate. The second pulley 24 drives the first pulley 8 directly connected to it to rotate through the second belt 24. The first pulley 8 drives the other first pulleys 8 to rotate through the transmission of the first belt 9. The first pulley 8 drives the coaxial straightening roller 7 to rotate, straightening the steel strip while moving the steel strip to feed. The first electric push rod 11 extends and drives the cutting blade 12 to move downward to cut the steel strip.
