Description

Technical Field

[0001] The utility model relates to the field of crimping tooling, in particular to a PTFE buckle crimping tooling. Background Art

[0002] PTFE fasteners refer to fasteners or joints made of polytetrafluoroethylene. These fasteners are usually used to connect and fix various components of PTFE piping systems, such as pipes, valves, pumps, etc. Due to PTFE's excellent corrosion resistance, high temperature resistance and non-adhesion properties, PTFE fasteners are widely used in chemical, pharmaceutical and food processing fields. They can ensure the safety, reliability and durability of the piping system while maintaining the purity of the inside of the pipe and the integrity of the fluid. PTFE fasteners usually have excellent wear resistance and chemical stability, and can maintain stable performance under extreme conditions. Therefore, they are widely used in various industrial fields and special environments.

[0003] The connection between the pressure head and the support plate of some existing traditional crimping machines and the device is often connected by bolts, etc., and when the crimping machine needs to replace the pressure head according to products of different sizes, it is necessary to loosen and tighten multiple bolts, which results in a relatively time-consuming installation and disassembly of the pressure head and the support plate, and multiple bolts may be accidentally lost during the installation and disassembly process, which is quite inconvenient. At the same time, some existing traditional crimping tools lack a limit assembly to limit the parts to be crimped when the pressure plate is crimped, resulting in some parts being offset during crimping, thereby affecting product quality and not being practical enough.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1The utility model provides an embodiment: a PTFE buckle crimping tool, including a base 1, which is connected to various components. A bracket 2 is fixedly connected to the rear side of the top surface of the base 1 for installing a cylinder 3. The middle part of the bottom surface of the bracket 2 is fixedly connected to the cylinder 3 for providing power to the device. The bottom surface of the cylinder 3 is fixedly connected to a fixing member 4 for connecting with a connecting member 5. A connecting member 5 is provided at the lower part of the fixing member 4 for installing a pressing plate 6 and a supporting plate 7. A pressing plate 6 is provided at the lower part of the connecting member 5 for crimping. A positioning assembly is provided at the lower part of the pressing plate 6 for limiting and fixing the parts during crimping. A supporting plate 7 is provided at the middle part of the top surface of the base 1 for cooperating with the pressing plate 6 for crimping. A connecting member 5 is provided at the bottom surface of the supporting plate 7 for connecting with the base 1.

[0033] See also Figure 2 - Figure 4 The connecting member 5 includes a connecting column 51 for connecting with other components. The connecting column 51 at the upper part is fixedly connected to the pressure plate 6, and the connecting column 51 at the lower part is fixedly connected to the support plate 7. The top of the connecting column 51 is fixedly connected with a circular plate 55 for matching with the mounting ring 52. The top of the circular plate 55 is fixedly connected with an insert block 54 for connecting with the slot. The connecting member 5 also includes a mounting ring 52 for connecting various components. The mounting ring 52 is movably connected to the connecting column 51. The top of the mounting ring 52 is fixedly connected with a threaded tube 53 for connecting with the connecting groove.

[0034] Specifically, the bottom surface of the fixing member 4 is provided with a No. 1 connecting groove 41 for matching with the threaded tube 53, and the threaded tube 53 is threadedly connected thereto. The middle part of the bottom surface of the fixing member 4 is provided with a No. 1 clamping groove 42, and the insert block 54 is clamped therewith for matching with the connection of the connecting member 5.

[0035] like Figure 5 As shown, the positioning assembly includes a positioning block 62 for positioning and fixing the parts. A slide groove 61 is provided on the bottom surface of the pressure plate 6 for cooperating with the connection of the positioning block 62. The positioning block 62 is slidably connected thereto. A spring 63 is fixedly connected between the positioning block 62 and the slide groove 61 for resetting the positioning block 62.

[0036] like Figure 6 As shown, the bottom surface of the support plate 7 is fixedly connected with a plurality of supporting legs 71 for supporting the support plate 7. A No. 2 connecting groove 11 is provided in the middle of the base 1 for matching the connection of the connecting piece 5. The No. 2 connecting groove 11 is threadedly connected to the threaded tube 53 located at the bottom. A No. 2 card slot 12 is provided in the middle of the base 1. The No. 2 card slot 12 is card-engaged with the plug block 54 located at the bottom for matching the connection of the support plate 7.

[0037] Working principle: When in use, when it is necessary to replace the pressing plate 6 and the supporting plate 7 according to the size of the processed product, first rotate the mounting ring 52 located at the top, and the mounting ring 52 will drive the threaded tube 53 to rotate. After the threaded tube 53 is separated from the No. 1 connecting groove 41, pull the connecting column 51 downward, and the connecting column 51 will drive the plug 54 to separate from the No. 1 slot 42. Then, the pressing plate 6 can be separated from the cylinder 3. The steps for separating the supporting plate 7 from the base 1 are the same. First, rotate the mounting ring 52 to separate the threaded tube 53 from the No. 2 connecting groove 11, and then separate the plug 54 from the No. 2 slot 1 2 can complete the separation of the support plate 7 and the base 1, then the plug block 54 of the connecting piece 5 on the replaced pressure plate 6 is inserted into the No. 1 card slot 42, and then the threaded tube 53 is tightened with the No. 1 connecting slot 41. When the threaded tube 53 and the No. 1 connecting slot 41 are fixed, the gap between the mounting ring 52 and the threaded tube 53 will clamp the circular plate 55, and the connecting column 51 connected to the circular plate 55 will also be fixed, so that the pressure plate 6 is connected to the cylinder 3. The installation steps of the support plate 7 are the same as above, so that the plug block 54 is clamped with the No. 2 card slot 12, and the threaded tube 53 is connected with the No. 2 connecting slot 11.

[0038] When the pressure plate 6 is crimping, the cylinder 3 will push the pressure plate 6 downward, and the positioning block 62 will first contact the part to be processed to fix it in position. As the pressure plate 6 is continuously pressed downward, the positioning block 62 will slide into the slide groove 61 to squeeze the spring 63. When the pressure plate 6 completely contacts the part and squeezes it, the positioning block 62 will completely retreat into the slide groove 61. When the crimping is completed, the cylinder 3 drives the pressure plate 6 to move upward, and the positioning block 62 will be pushed back to its original position by the spring 63.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
