Technical Field

[0001] The invention relates to the technical field of pipe fitting forming, and in particular to a large-diameter high-strength metal three-way pipe fitting forming device and method. Background Art

[0002] In the existing stainless steel elbow forming process, an elbow pushing machine is often used to push and form the elbow, and then multiple sets of tooling are used to shape and grind the elbow, which has the problems of low forming efficiency and high investment cost.

[0003] The Chinese patent with the announcement number CN114433689A discloses a stainless steel elbow forming process including the following steps: blank preparation, bending forming, tire shaping, heat treatment and post-processing, wherein the bending forming step is to sleeve the elbow tube blank on the core rod of the elbow pusher, the induction heating coil is sleeved on the end of the core rod, the cooling water pump and the power supply are started, and then the elbow pusher is started to move the elbow tube blank toward the end of the core rod, so that the elbow tube blank is heated and formed by the induction heating coil; the tire shaping step is to place the bent elbow into the shaping device for shaping.

At this time, a docking groove reserved on the top of the mold can be integrally formed on the surface of the tee shell to reserve a docking bracket. The two semicircular tee shells produced by the device are docked with each other and connected to each other through the docking bracket, thereby achieving the combination effect of the tee.

[0024] In summary, the present invention includes at least one of the following beneficial effects: The device can effectively improve the production efficiency and stability of metal tees. The docking groove structure can reserve a docking bracket on the shell after production is completed, thereby facilitating the efficiency of subsequent docking combination. At the same time, the device feeds from both sides and discharges from the side according to the overflow state inside the outlet pipe, which can ensure that there are no hollow bubbles inside the mold, thereby ensuring the production stability of the device.

[0027] The following is combined with Figure 1-4 The present invention is described in further detail. Example

[0031] The lifting component 3 includes a support column 301 connected to the base 1, the top of the support column 301 is connected to a top bracket 302, the top of the top bracket 302 is connected to a lifting electric telescopic rod 303, the bottom telescopic end of the lifting electric telescopic rod 303 passes through the top bracket 302 and is connected to a lifting plate 304, the bottom of the lifting plate 304 is connected to a pressing piece 305, the bottom of the pressing piece 305 is provided with an arc-shaped protrusion 306, the two sides of the arc-shaped protrusion 306 are provided with penetrating feeding holes 307, and the side of the arc-shaped protrusion 306 is provided with a discharge hole 308.

[0032] The feed component 4 includes a raw material box 402 connected to the top bracket 302 , a feed pipe 401 is connected to the side of the raw material box 402 , and the other end of the feed pipe 401 is connected to the feed hole 307 .

[0033] The top of the top bracket 302 is connected to an electric telescopic rod 403, the top telescopic end of the electric telescopic rod 403 is connected to a U-shaped connecting rod 404, the other end of the U-shaped connecting rod 404 is connected to a pressure plate 405, the pressure plate 405 is slidably connected to the inside of the raw material box 402, and an air outlet pipe 406 is provided through the top of the lifting plate 304, and the bottom of the air outlet pipe 406 is connected to the discharge hole 308.

[0034] A sealing member is provided on the side of the blocking plate 204, and an arc-shaped groove is provided on the top of the mold 201. The side of the arc-shaped groove is in contact and extruded with the sealing member. There is a gap between the arc-shaped protrusion 306 at the lowest point and the arc-shaped groove. When the arc-shaped protrusion 306 is at the lowest point, the pressing member 305 is in contact with the top of the mold 201.

[0035] The specific working principle is: this device can effectively realize the production of large-diameter tees. Compared with traditional devices, this device can achieve the compatibility of large-diameter production by producing semi-circular raw materials and then combining them.

[0036] When the device is in use, the casting production effect of the device is achieved by installing a mold 201 of a corresponding diameter on the base 1. At this time, the structure of the sliding base 202 can drive the blocking plate 204 to slide, thereby ensuring the side sealing of the mold 201. At this time, the pressing piece 305 is driven downward by the top lifting electric telescopic rod 303, thereby forming a casting space for the device.

Example

[0037] like Figure 1-Figure 4 As shown, in order to solve the existing problems, based on the same concept as the above-mentioned embodiment 1, a large-diameter high-strength metal three-way pipe forming method includes the following steps: S1: Sliding blocking plate 204 step, in which the sliding base 202 drives the connecting member 203 and the blocking plate 204 to slide, so that the blocking plate 204 is docked with the arc-shaped groove on the side of the mold 201 to achieve a sealing effect on the side of the arc-shaped groove; S2 is a step of lowering the pressing member 305. In this step, the lifting plate 304 is driven to slide downward by lifting the electric telescopic rod 303, so that the pressing member 305 is close to the mold 201. At this time, the pressing member 305 is in contact with the top of the mold 201, and a gap is formed between the arc-shaped protrusion 306 and the arc-shaped groove for raw material storage; S3 adds a step of pouring raw materials. In this step, the raw materials are poured under pressure, and the raw materials in the raw material box 402 are squeezed through the pressure plate 405, and then pass through the arc-shaped protrusion 306 through the feed pipe 401, and enter the gap between the groove and the protrusion. At this time, the pressure plate 405 is stably transmitted through the electric telescopic rod 403 and the U-shaped connecting rod 404 structure. During the process of the raw materials entering, the air originally existing in the gap between the groove and the protrusion is discharged from the exhaust pipe 406.

[0038] The step of adding casting raw materials, after the casting is completed, is to cool the casting raw materials by natural cooling to shape them. At this time, the blocking plate 204 can slide horizontally through the sliding base 202, so as to open the side of the arc-shaped groove. At the same time, the pressing part 305 is driven to rise by the lifting electric telescopic rod 303, thereby facilitating the discharge of the shaped raw materials from the inside of the device.

[0039] A step of pouring raw materials is added. After two productions, two semicircular tee shells are obtained. At this time, the docking groove 205 reserved on the top of the mold 201 can be integrally formed on the surface of the tee shell to reserve a docking bracket. The two semicircular tee shells produced by the device are docked with each other and connected to each other through the docking bracket, thereby achieving the combination effect of the tee.

[0040] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
