[0025] Pipes are equipment parts that are often needed in workshop production activities. In order to facilitate maintenance, pipelines are usually divided into sections and connected with quick connectors. Existing quick connectors are usually formed by integral turning of thick-walled pipes, which is time-consuming and labor-intensive, with low processing efficiency, high requirements on processing materials, and high production costs.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0027] A coordinate system XY is set in this article, wherein the positive direction of the X axis represents the right, the negative direction of the X axis represents the left, the positive direction of the Y axis represents the top, and the negative direction of the Y axis represents the bottom.

[0028] In addition, a brief explanation is given for the orientations involved in this specific implementation: the directions or positional relationships indicated by "up", "down", "left", "right", etc., etc. of each structural member mentioned below refer to the orientations or positional relationships shown in the accompanying drawings; these positional relationships are only for the convenience of description and simplified description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] like Figure 1As shown, an embodiment of the present invention provides a processing device for a quick connector, the quick connector includes a first component 100 and a second component 200, the first component 100 is processed by a first workpiece 101, the second component 200 is processed by a second workpiece 201, the first workpiece 101 is provided with a first processing hole, and the second workpiece 201 is provided with a second processing hole. Specifically, the first workpiece and the second workpiece are both flat plate structures, and the first workpiece is provided with a first processing hole in the middle, and the second workpiece is provided with a second processing hole in the middle, the first component is a U-shaped structure, and the second component is a bowl-like structure. The first component and the second component can be assembled to obtain a quick connector. The present invention disassembles the existing quick connector into a first component and a second component, and then processes the first component and the second component respectively through a first mold and a second mold, and then assembles the first component and the second component to obtain a quick connector, which simplifies the manufacturing process and facilitates mass production. The quick connector manufactured by the present invention is hollow inside, which reduces the weight of the quick connector and is easier to be welded with a pipe. The invention comprises a first die 1 and a second die 2. The first die 1 is used to process the first workpiece 101 into the first component 100. Specifically, the first die stamps the first workpiece into the first component, and the second die stamps the second workpiece into the second component. The second die 2 is used to process the second workpiece 201 into the second component 200. After the first component 100 and the second component 200 are assembled, they are suitable for fixed connection with pipes. Since the pipes do not need to be cut, in this embodiment, the pipes can be ordinary pipes, thereby reducing production costs.

[0031] The processing device for quick connectors of the present invention processes a first workpiece into a first component by setting a first mold, processes a second workpiece into a second component by setting a second mold, and then assembles the first component and the second component into a quick connector. The quick connector is processed in steps, the process is simple, and batch production of the quick connector is convenient. The processing material requirements are not high, and the production cost is reduced.

[0032] The first mold 1 includes a first upper mold plate 11 and a first lower mold plate 12. The first upper mold plate 11 is provided with an annular ejector 13. The annular ejector 13 encloses an open accommodating cavity, and the opening of the open accommodating cavity faces downward. The first lower mold plate 12 is a groove structure. In this embodiment, the first lower mold plate is a flat plate structure and a groove is provided on the upper surface of the first lower mold plate. In other embodiments, the first lower mold plate can be assembled from a flat plate and a groove wall of an annular structure. A core 14 adapted to the open accommodating cavity is provided on the bottom wall of the first lower template 12, and the core 14 is suitable for being sleeved with the first processing hole of the first workpiece 101, and a workpiece forming cavity 15 is formed between the circumferential inner wall of the first lower template 12 and the circumferential outer wall of the core 14, and the annular ejector 13 is used to cooperate with the workpiece forming cavity 15 to process the first workpiece 101 into the first component 100. Specifically, when the first mold stamps the first workpiece, the annular ejector generates a force on the middle part of the annular edge of the first workpiece, and the middle part of the annular edge of the first workpiece rapidly protrudes downward, and due to the limiting effect of the workpiece forming cavity on the left and right sides of the annular edge of the first workpiece, the left and right sides of the annular edge of the first workpiece are close to and fit into the annular ejector, thereby shaping the first workpiece into the first component.

[0033] The radial diameter of the end of the annular ejector 13 toward the first lower mold plate 12 gradually decreases in the direction toward the first lower mold plate 12, and the top end thereof is a curved surface structure. Specifically, the cross-section of the end of the annular ejector 13 toward the first lower mold plate 12 in the plane where the XY is located is an elliptical shape, which can achieve stamping and molding of the first workpiece without causing damage to the first workpiece.

[0034] A mounting groove 16 is provided on the bottom wall of the first lower template 12, and the core 14 is arranged in the mounting groove 16. The core can be easily removed from the first lower template. After the first workpiece is stamped into the first component, the core can be taken away to facilitate the removal of the first component.

[0035] like Figure 2 As shown, the workpiece forming cavity 15 includes a molding cavity 151 and a dropping cavity 152. The molding cavity 151 is arranged above the dropping cavity 152 and is connected to the dropping cavity 152. The diameter of the dropping cavity 152 is larger than the diameter of the molding cavity 151. The molding cavity plays a role in molding the first workpiece. After the first workpiece is molded into a first component, it falls into the dropping cavity. It can be understood that the annular ejector returns after molding the first workpiece in the molding cavity, and then the processed first component falls into the dropping cavity. In this way, excessive stamping of the first workpiece by the annular ejector can be avoided, the molding quality of the first component is guaranteed, and the first component can be easily taken out of the dropping cavity without causing damage to the first component.

[0036] A first curved surface 17 is provided at the upper end of the core 14, and a second curved surface 18 is provided at the circumferential inner side wall of the upper end of the first lower mold plate 12. The first curved surface 17 and the second curved surface 18 are arranged in mirror symmetry. During the stamping process of the first workpiece, the setting of the first curved surface and the second curved surface can achieve a transition buffering effect, making the molding process of the first workpiece softer, improving the molding quality of the first workpiece, and avoiding the molding process of the first workpiece being too stiff, thereby causing molding defects of the first workpiece.

[0037] like Figure 2 As shown, the workpiece molding cavity 15 also includes a first workstation cavity 153, which is arranged above the molding cavity 151 and connected to the molding cavity 151. Specifically, the diameter of the first workstation cavity is adapted to the diameter of the annular edge of the first workpiece, and the diameter of the first workstation cavity is larger than the diameter of the molding cavity. The first workstation cavity 153 is used to place the annular edge of the first workpiece 101, and then the first workpiece is molded by stamping the annular ejector.

[0038] like Figure 3 As shown, the second mold 2 includes a second upper template 21 and a second lower template 22. A stamping piece 23 is arranged on the second upper template 21. The side of the stamping piece 23 is a curved surface structure, and the stamping piece as a whole is roughly a conical structure. The second lower template 22 is provided with a pressing cavity 24 adapted to the stamping piece 23. The pressing cavity is a through-hole structure. Specifically, the inner side of the pressing cavity coincides with the outer contour of the stamping piece, so as to realize the joint shaping of the second workpiece during the movement of the stamping piece to the pressing cavity. The stamping piece 23 is suitable for passing through the second processing hole of the second workpiece 201 and cooperating with the pressing cavity 24 to process and shape the second workpiece 201 into the second component 200. When the stamping piece shapes the second workpiece, the lower end of the stamping piece first passes through the second processing hole of the second workpiece. As the diameter of the plane where the stamping piece contacts the second processing hole gradually increases, the second workpiece is driven to move downward, and the second workpiece is squeezed between the stamping piece and the inner side wall of the pressing cavity, thereby shaping the second workpiece.

[0039] like Figure 3 As shown, it also includes a second workstation cavity 25, which is arranged above the pressing cavity 24 and is connected to the pressing cavity 24. The diameter of the second workstation cavity is larger than the diameter of the upper opening of the pressing cavity, and the diameter of the second workstation cavity is adapted to the diameter of the second workpiece. The second workstation cavity 25 is used to place the second workpiece 201, and then the second workpiece is shaped by a stamping part.

[0040] like Figure 3As shown, it also includes a guide member 26. Specifically, the guide member is a frustum structure. The guide member 26 is arranged at the lower end of the stamping member 23. The guide member and the stamping member are integrally formed. The lower end of the pressing cavity 24 is an open structure. When the stamping member and the pressing cavity cooperate to shape the second workpiece, the guide member 26 is used to pass through the second processing hole of the second workpiece 201 and extend out of the opening, so that the stamping member can be quickly positioned relative to the second lower template, which is convenient for stamping the second workpiece.

[0041] Another embodiment of the present invention provides a processing method for a quick connector, which is applied to the processing device for the quick connector as described above, comprising: placing a first workpiece 101 into a first workstation cavity 153; driving a first upper template 11 to move downward and press the first workpiece 101 by an external press, and through the cooperation of an annular positioning member and a workpiece forming cavity, the first workpiece 101 is processed into a first component 100 under the joint action of an annular ejector 13 and a workpiece forming cavity 15 on the first upper template 11; placing a second workpiece 201 into a second workstation cavity 25; driving a second upper template 21 to move downward and press the second workpiece 201 by an external press, and the second workpiece 201 is processed into a second component 200 under the joint action of a stamping member 23 and a pressing cavity 24 on the second upper template 21; placing the first component 100 into the second component 200 and welding the outer wall of the first component 100 and the inner wall of the second component 200 together to assemble and form a quick connector.

[0042] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
