Description

Technical Field

[0001] The utility model relates to the technical field of tee extrusion, in particular to a seamless oblique tee extrusion device. Background Art

[0002] Due to its manufacturing process and the excellent performance of raw materials, seamless tees are usually used for pipe connections under harsh conditions such as high temperature, high pressure, acid and alkali, and are widely used in petrochemical, electric power, pharmaceutical, food and other fields. Seamed tees are mostly used for low-pressure pipe connections, such as tap water pipes, bicycle racks and other fields. In high-end industries, seamless tees are more widely used. The production process of seamless tees has a variety of methods such as hot rolling, forging and cold processing. Among them, the hot rolling production process refers to heating the steel billet to a certain temperature, and then transforming the steel billet into a seamless tee through a rolling process. The forging production process refers to heating the steel billet to a certain temperature, hitting and squeezing it with equipment such as a sledgehammer or a press, so that the steel billet is transformed into a seamless tee. Cold processing production technology refers to processing steel billets at room temperature by drawing, cold rolling or cold drawing to achieve the purpose of transforming the steel billets into seamless tees. In order to reduce energy consumption and increase production capacity, most of them adopt cold rolling. When using the existing cold rolling method to prepare seamless oblique tees, the extrusion device generally uses high-pressure gas to pressurize the steel billet into a seamless oblique tee. However, in this way, the inside of the steel billet is prone to produce lines. At the same time, the loading of the steel billet and the unloading of the seamless oblique tee are also time-consuming. Therefore, a seamless oblique tee extrusion device with good extrusion molding effect and high pressure molding efficiency is designed. Utility Model Content

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.

[0022] Example:

[0023] See also Figure 1-4 A seamless oblique three-way extrusion device comprises a lower mold 1 and an upper mold 2 which can move up and down. The lower mold 1 is provided with multiple and can move forward and backward under the upper mold 2. It also comprises two groups of sealing chucks 14 respectively on the left and right sides of the lower mold 1 and the upper mold 2, and a lubricating liquid tank 6 located below the upper mold 2 and the sealing chucks 14. The left and right sides of the lubricating liquid tank 6 are provided with pressurizing mechanisms connected to the sealing chucks 14 on their respective sides. The input ends of the two pressurizing mechanisms are connected to the bottom of the lubricating liquid tank 6. Furthermore, the angles of the multiple upper molds 2 can be set to be the same or different, and the angles can be individually customized according to the situation.

[0024] Specifically, the left and right sides of the lubricating tank 6 are each provided with a horizontal driving cylinder 8 for driving the sealing chuck 14 on the respective side to move left and right. The horizontal driving cylinder 8 is fixedly mounted on the top of the lubricating tank 6 through the hanger 7. The sealing chuck 14 can be pushed to move left and right by the horizontal driving cylinder 8, thereby facilitating the sealing chuck 14 to clamp the left and right sides of the lower mold 1 and the upper mold 2 and seal the end of the billet. The horizontal driving cylinder 8 can be raised to a height where the input end of the horizontal driving cylinder 8 is flush with the sealing chuck 14 through the hanger 7, thereby improving the stability of the horizontal adjustment.

[0025] Specifically, it also includes a card table 5 and a forward and backward moving mechanism for driving the card table 5 to move forward and backward. The card table 5 is provided with a plurality of card slots arranged at front and rear intervals for slidingly engaging with the lower mold 1. The forward and backward moving mechanism can drive the card table 5 to move forward and backward, thereby allowing the plurality of lower molds 1 slidingly engaged on the card table 5 to move forward and backward.

[0026] Specifically, a support frame 3 fixedly connected to the lubricating liquid tank 6 is provided on the top of the upper mold 2, and a lifting drive cylinder 4 is fixedly installed on the support frame 3. The bottom output end of the lifting drive cylinder 4 is fixedly connected to the top of the upper mold 2. The lifting drive cylinder 4 is used to drive the upper mold 2 to perform lifting movements, thereby facilitating the adjustment of the height of the upper mold 2.

[0027] Specifically, the pressurizing mechanism includes a slide 10 that slides with the lubricating tank 6, a pressurizing pump 11 is fixedly installed on the slide 10, the output end of the horizontal driving cylinder 8 is fixedly connected to the connecting frame 9, the bottom of the connecting frame 9 is fixedly connected to the slide 10, and the sealing chuck 14 is fixedly connected to the connecting frame 9 through a plurality of connecting rods 13. The input end of the pressurizing pump 11 extends into the inner bottom of the lubricating tank 6 through a suction pipe 12, and the output end of the pressurizing pump 11 is fixedly connected to the sealing chuck 14 through a pressurizing pipe 15. The pressurizing mechanism can move left and right synchronously with the left and right movement of the sealing chuck 14. When the pressurizing pump 11 is started, the lubricating liquid in the lubricating tank 6 can be extracted through the suction pipe 12 and pressurized into the steel billet through the pressurizing pipe 15.

[0028] Specifically, the forward and backward moving mechanism includes a guide groove 16 fixedly connected to the bottom of the lubricating liquid tank 6 through multiple support rods, a screw 17 and a driving motor 19 for driving the screw 17 to rotate are provided on the guide groove 16, a slider 18 threadedly connected to the screw 17 for guiding and sliding cooperation with the guide groove 16, and the top of the slider 18 is fixedly connected to the bottom of the card table 5. Further, the driving motor 19 is fixedly installed at the bottom of the guide groove 16 and is located below the screw 17. The output end of the driving motor 19 is synchronously transmitted with the screw 17 through a synchronous belt 20. When the driving motor 19 is started, the output end of the driving motor 19 rotates clockwise or counterclockwise, and the screw 17 is driven to rotate clockwise or counterclockwise through the synchronous transmission cooperation of the synchronous belt 20, thereby driving the slider 18 to move forward and backward in the guide groove 16, thereby driving the card table 5 to move forward and backward, and thereby driving multiple lower molds 1 to move forward and backward.

[0029] When in use, the steel billet is placed on one of the lower molds 1, and then the lower mold 1 is moved to a position directly below the upper mold 2, and then the upper mold 2 is moved downward to clamp the steel billet, and then the sealing chucks 14 on both sides clamp the lower mold 1 and the upper mold 2 on both sides respectively to seal the two ends of the steel billet, and then the two pressurizing mechanisms are started to squeeze the lubricating liquid in the lubricating liquid tank 6 into the steel billet. As the extrusion proceeds, the lubricant enters the steel billet, causing the bottom of the steel billet at the lower mold 1 to deform, so that the steel billet is extruded to form a seamless oblique tee billet with one end blocked, and then the two sealing chucks can be used to squeeze the lubricating liquid in the lubricating liquid tank 6 into the steel billet. The disk 14 is moved to both sides, and then the upper mold 2 is moved upward, so that the lubricating liquid on the upper part of the seamless oblique tee blank with one end blocked flows back into the lubricating liquid tank 6, and the material is loaded while pressurizing, and then the lower mold 1 is taken down with the seamless oblique tee blank with one end blocked and moved back and forth, so that the next lower mold 1 drives the billet to the position directly below the upper mold 2, and the above operation is repeated for extrusion molding. At the same time, the unloading and loading operations are performed, and the lubricating liquid on the upper part of the seamless oblique tee blank with one end blocked is poured back into the lubricating liquid tank 6, so that the lubricating liquid can be reused.
