[0021] In order to make the technical personnel of the technical field better understand the present utility model scheme, the technical scheme in the present utility model embodiment will be clearly and completely described below in conjunction with the drawings in the present utility model embodiment. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by the technical personnel in the technical field belonging to the present utility model. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.
[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0023] like Figure 1-Figure 5 As shown, a snake spring closing machine includes a fixed block 1 for fixing the snake spring to be closed, a pressing block 2 for pressing the snake spring to be closed, and a driving mechanism for driving the pressing block 2 to reciprocate forward and backward. A limiting block 4 is arranged at intervals on one side of the fixed block 1. The pressing block 2 is arranged between the fixed block 1 and the limiting block 4, and the pressing block 2 is slidably connected to the limiting block 4. A discharge groove 11 is provided on the top of the fixed block 1. The discharge groove 11 runs through from left to right, so that the end of the snake spring to be closed can extend out of one side of the fixed block 1, and a pressing groove 21 is provided on the pressing block 2.
[0024] The length of the discharge groove 11 is equal to the length of the snake spring straight section L, and the width of the discharge groove 11 is 1-2mm larger than the diameter of the snake spring. The length design of the discharge groove 11 is conducive to ensuring the length of the snake spring end extending out of the discharge groove 11. The groove width is slightly larger than the snake spring wire diameter, which is conducive to discharge and reduces the deviation caused by manual error.
[0025] Preferably, the longitudinal cross section of the discharge trough 11 is a U-shaped structure. The bottom surface of the U-shaped structure is an arc structure, which is compatible with the line shape of the snake spring and is convenient for the snake spring workpiece to enter.
[0026] Preferably, the pressing notch 21 is a V-shaped groove, and the bottom of the V-shaped groove is a chamfered structure. Since the pressing notch 21 is a V-shaped structure, it can correct the centering of the spring end during the pressing process.
[0027] Preferably, the arc radius of the bottom chamfer of the V-shaped groove is equal to the arc radius of the bottom of the discharge groove 11, and the centers of the two arcs are on the same horizontal line, and the radii of the two arcs are 1-2 mm larger than the radius of the snake spring.
[0028] The snake spring closing machine also includes a fixed base plate 5, and the fixed block 1, the limiting block 4, and the driving mechanism are all fixed on the fixed base plate 5 to form an integral structure. When in use, it is only necessary to fix the fixed base plate 5 to the operating table with screws.
[0029] In this embodiment, the driving mechanism is a double-force cylinder 3, which is connected to the fixed bottom plate 5 through a rear fixed plate 6, and the top pressure block 2 is threadedly connected to the telescopic end of the double-force cylinder 3. The top pressure block 2 is connected in a screw connection manner for easy disassembly and assembly.
[0030] The snake spring closing machine also includes a triangular reinforcing plate 7, which is arranged on one side of the rear end of the double force cylinder 3, and the triangular reinforcing plate 7 is respectively welded to the fixed bottom plate 5 and the rear fixed plate 6. The triangular reinforcing plate 7 plays a role of strengthening the fixation.
[0031] The snake spring closing machine also includes an external foot switch (not shown) for controlling the action of the double-strength cylinder 3, and the foot switch is connected to the double-strength cylinder 3 through an air pipe. When in use, after the material is discharged in the discharge trough 11, the operator only needs to control the action of the double-strength cylinder 3 by stepping on the foot switch.
[0032] When in use, the operator puts the end to be closed into the discharge trough 11, and moves the top pressure block 2 with the end to be closed, and then steps on the foot switch to control the action of the double force cylinder 3, driving the top pressure block 2 to move forward to press the closing end of the snake spring and then reset, thereby completing the closing of one end of the snake spring, and then changing the other end of the snake spring to discharge and close the material, completing the closing of both ends of the snake spring. The device is small in size, exquisite and practical. Compared with the manual lever method, it improves work efficiency and reduces the labor intensity of workers.
[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
