Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal gasket assembly, in particular to a winding gasket assembly tool. Background Art
[0002] Metal wound gasket is a widely used sealing gasket. It is the gasket with the best resilience among semi-metallic sealing gaskets. It is made of V-shaped or W-shaped thin steel strips and various fillers alternately wound together. It can withstand high temperature and high pressure and adapt to ultra-low temperature or vacuum conditions. By changing the material combination of the gasket, the chemical corrosion problem of various media on the gasket can be solved. When using it, we install the metal wound gasket on the end face of the flange, and the two flanges are closed to clamp the metal wound gasket, so that the metal wound gasket is interference-fitted between the two flanges, which can play a strong sealing role. However, in actual use, when the metal wound gasket is assembled into the flange, it is affected by the tolerance of the flange end face assembly groove and the stress and tolerance of the metal wound gasket itself. The metal wound gasket is easy to be assembled misaligned, and even the stress warping of the edge and center position may occur. The surface of the assembled metal wound gasket is uneven, which will reduce the sealing performance in actual use. The existing tooling is not specifically designed for the uneven end face of the metal wound gasket, so it is necessary to improve the assembly tooling. Utility Model Content
[0003] Based on this, it is necessary to provide a winding pad assembly tool to address the above problems.
[0004] A winding gasket assembly tool comprises a lower mold for supporting a flange, the lower mold is in a truncated cone shape, a positioning pin and a positioning hole are installed on the end surface of the lower mold, the positioning pin and the positioning hole are arranged in a corresponding manner, one end of a cross bar is movably connected to the upper end of the positioning pin, and a positioning plug is provided at the other end of the cross bar, the positioning plug is movably inserted into the positioning hole, a spinning rod is provided in the middle of the cross bar, the spinning rod is connected to the cross bar through a threaded structure, and a pressure plate for crimping a flange is provided at the lower end of the spinning rod.

[0013] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0014] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0016] like Figures 1-2As shown, a winding gasket assembly tool includes a lower mold 1 for supporting a flange 100, the lower mold 1 is in a truncated cone shape, and a positioning pin 2 and a positioning hole 3 are installed on the end face of the lower mold 1, the positioning pin 2 and the positioning hole 3 are arranged in alignment, one end of a cross bar 4 is movably connected to the upper end of the positioning pin 2, and a positioning plug 5 is arranged at the other end of the cross bar 4, and the positioning plug 5 is movably inserted into the positioning hole 3, a spinning rod 6 is arranged in the middle of the cross bar 4, and the spinning rod 6 is connected to the cross bar 4 through a threaded structure, and a pressure plate 61 for crimping the flange 100 is arranged at the lower end of the spinning rod 6. Specifically, the lower mold 1 is made of metal and is concave in the middle to accommodate the flange 100 for assembling the metal wound gasket. It is understandable that the side of the flange 100 with the metal wound gasket is facing upward. When the metal wound gasket is assembled into the flange 100, a hot assembly method can be adopted, that is, the flange is heated and then the metal wound gasket is installed. In order to prevent the edge of the metal wound gasket from warping up after assembly, resulting in unevenness, we apply a vertical force to it through the pressure plate 61. The specific operation process is as follows: the operator rotates the spinning rod 6, driving the pressure plate 61 to rotate and press down at the same time, acting on the flange surface to flatten the gasket regularly. The pressure can be continuously provided and the operation is simple. When the pressing is completed, the spinning rod 6 rotates in the opposite direction, the pressure plate 61 rises, and at the same time separates the positioning rod 5 from the positioning hole 3, and rotates the cross bar 4 around the positioning pin shaft 2 so that the pressure plate 61 and the flange 100 are misaligned, and the flange 100 can be taken out. When it is necessary to regularly assemble the gasket of the next flange 100, it is only necessary to rotate the cross bar 4 again around the positioning pin shaft 2 so that the positioning rod 5 is reinserted into the positioning hole 3, so that the cross bar 4 is reset and the pressure plate 61 is repositioned above the flange 100, and the operation is repeated. The entire tooling structure is simple, the cost is low, and the operation difficulty is small, so that the metal gasket on the flange 100 can be regularly assembled at a low cost.
[0017] like Figures 1-2 As shown, the spinning rod 6 and the lower mold 1 are coaxial, and when the spinning rod 6 rotates and drives the pressure plate 61 to press down, it can act on the metal wound gasket on the end face of the flange 100, and the pressure applied is uniform, avoiding uneven force on different parts of the metal wound gasket.
[0018] like Figure 3 As shown, the positioning rod 5 includes a sleeve 51, a rod 52 and a spring 53. The upper side of the sleeve 51 is vertically connected to the cross bar 4. The rod 52 movably passes through the sleeve 51. The spring 53 is sleeved on the rod 52. The spring 53 abuts against the inner top of the sleeve 51. The lower end of the rod 52 is movably inserted into the positioning hole 3.
[0019] like Figures 1 to 3As shown, a pull ring 521 is provided at the top of the insertion rod 52. Specifically, the operator can pull the insertion rod 52 through the pull ring 521 to plug or separate the insertion rod 52 from the positioning hole 3, which is extremely convenient and quick to operate.
[0020] like Figure 3 As shown, a cone head 522 is provided at the bottom of the insertion rod 52. The cone head 522 is larger at the top and smaller at the bottom. It can be smoothly inserted into the positioning hole 3 and will not be stuck at the opening of the positioning hole 3. The cone head 522 can also support the spring 53 and seal the spring 53. There is no need to set other stopping structures on the insertion rod 52 to prevent the spring 53 from falling out.
[0021] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
