Description

Technical Field

[0001] The utility model belongs to the technical field of pipe fitting processing, and particularly relates to a manufacturing device for a new type of three-way PE pipe fitting. Background Art

[0002] For the production of conventional PE pipe fittings, an injection mold is first designed and manufactured, and then the mold is installed on an injection molding machine. The plasticized PE material is injected into the mold through the injection molding machine. After the workpiece is pressure-maintained and cooled, it is demolded from the mold to form the corresponding pipe fitting. For mass-produced products, the process is stable and the cost is low. However, for small-batch and multi-specification products, especially large-sized three-way pipe fitting products, the production process is very inconvenient and the cost is relatively high. To meet the needs of customers, a manufacturing device for a new type of three-way PE pipe fitting needs to be designed to facilitate the production of pipe fittings. Summary of the Utility Model

Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0022] As Figures 1-6 shown, a novel three-way PE pipe fitting manufacturing device includes an upper die assembly and a lower die assembly. The upper die assembly includes an upper die bottom plate 1, an upper die inclined support 2 and a female die 3. The upper end of the upper die inclined support 2 is fixedly connected to the upper die bottom plate 1, and the lower end is fixedly connected to the female die 3. The upper die bottom plate 1 is connected to a press and can move up and down under the action of the press to provide pressure. The lower die assembly includes a lower die bottom plate 4, a lower die fixing plate 5, an auxiliary support rod assembly 6 and a male die 7. The male die 7 is arranged on the lower die fixing plate 5 at a corresponding position below the female die 3. The lower die fixing plate 5, the auxiliary support rod assembly 6 and the lower die bottom plate 4 are sequentially connected to jointly form a support frame for the three-way PE pipe fitting 8. A support inclined abutment block 9 is also arranged at the connection between the lower die fixing plate 5 and the lower die bottom plate 4. The three-way PE pipe fitting 8 is sleeved on the lower die fixing plate 5, and the end of the three-way PE pipe fitting 8 abuts against the inclined panel 92 of the support inclined abutment block 9.

[0023] Preferably, the female die 3 of the present utility model has a first arc surface 31 corresponding to the three-way PE pipe fitting 8 and an inner concave cavity 32. The male die 7 has a second arc surface 71 corresponding to the three-way PE pipe fitting 8 and an outer convex block 72. The outer convex block 72 and the inner concave cavity 32 are correspondingly arranged. The circumferential dimension of the inner concave cavity 32 is larger than the circumferential dimension of the outer convex block 72, and the distance between the two is the pipe diameter of the manufactured three-way pipe fitting. The outer peripheral side walls of the inner concave cavity 32 and the outer convex block 72 are both perpendicular to the lower die bottom plate 4.

[0024] Regarding the support frame of the three-way PE pipe fitting 8, the end of the lower die fixing plate 5 is fixedly connected to the lower die bottom plate 4, and one end of the auxiliary support rod assembly 6 is fixedly connected to the lower die bottom plate 4, and the other end is used for supporting and positioning the top of the lower die fixing plate 5.

[0025] Among them, the auxiliary support rod assembly 6 includes a first fixed rod 61 and a second movable rod 62. The first fixed rod 61 and the second movable rod 62 are rotatably connected by a pin shaft 63. The first fixed rod 61 is provided with a cavity, and the lower end of the second movable rod 62 extends into the cavity of the first fixed rod 61, so that the second movable rod 62 can only move unidirectionally.

[0026] When positioning and supporting, specifically, a vertical opening 51 is provided at the top of the lower die fixing plate 5 for supporting and positioning the top end of the second movable rod 62.

The supporting inclined abutting block 9 includes side plates 91 on both sides and an inclined panel 92, and the inclined panel 92 is vertically arranged with the lower die fixing plate 5.

[0028] When the device of the present utility model is working, first, the PE pipe is cut into pipe segments with the same length as the pipe fitting according to the length requirement of the pipe fitting. Then, the forming part of the pipe segment is placed at the end of the hot air blower for local heating. After the local area is heated and softened, it is inserted into the lower punch 7. The second movable rod 62 of the auxiliary support rod assembly 6 is closed. The female die 3 moves downward under the action of the press to press and form the pipe segment. After that, the press moves upward, the punch 7 and the female die 3 are separated, the auxiliary support rod assembly 6 is opened, and the formed workpiece is taken out. Figure 1 and Figure 7 are respectively schematic diagrams of the mold closing and mold opening states of the device.

[0029] The area between the concave cavity 32 and the outer convex block 72 of the device of the present utility model forms the three-way diameter of the three-way PE pipe fitting 8. During use, when producing three-way pipe fittings of different specifications, the upper and lower punches 7 and the female die 3 are replaced, and at the same time, the end face position of the formed pipe segment is appropriately adjusted, so as to facilitate the processing of various different specifications of PE three-way pipe fittings.
