Description

Technical Field

[0001] The present application relates to the field of mechanical processing technology, and in particular to a multifunctional pipe forming device for a swimming pool ladder. Background Art

[0002] Ribbing is to apply pressure to the metal pipe through the die to make it deform locally, forming a convex or concave rib structure. These ribs can increase the bending strength, torsional strength and compressive strength of the plate, and improve the stability and load-bearing capacity of the plate.

[0003] The pipes used on pool ladders often require ribs to accommodate the steps.

[0004] Hydraulic grooving machines are commonly used for rib pressing. The grooving machines press the pipe inside and outside through two forming dies, and simultaneously apply rotational and radial inward pressure to complete the rib pressing. However, when the pipe is long, the inner forming die cannot extend into the pipe. If the pipe is still rotating and only driven by the outer forming die, the forming accuracy of the pipe is often greatly reduced due to the easy shaking of the pipe during rotation, which cannot meet the production needs.

[0048] Specifically, the limiting slide groove 431 includes a rising portion 432 and a reset portion 433, and the reset portion 433 connects the two ends of the rising portion 432.

[0058] The pipe bending assembly can be performed synchronously with the rib pressing device 3 and the punching assembly.

[0060] According to the second embodiment of the present application, a multifunctional pipe forming device for a swimming pool ladder has the same structure as the first embodiment, and a new structure design is made for the cam assembly part according to the processing of different pipes.

Fig.15 As shown in the schematic diagram of the pipe structure, only the two sides of the pipe need to be ribbed, and there is a convex ridge between the two ribs.

The connecting rod 485 is fixedly connected to the sliding rod 484 and a third elastic 181 component is arranged between the guide mold 483 and the first support frame 31.

[0064] Specifically, when the rotating shaft 41 rotates, it drives the cam plate 47 to rotate and drives the control plate 49 to move longitudinally downward, so that the guide bracket 48 is tightened inward along the guide groove 491; when the movable protrusion 492 moves to the farthest end of the cam track 481, the cam plate 47 rotates and drives the control plate 49 to reset, and at the same time, the guide bracket 48 is reset under the action of the third elastic component 481.

[0065] Specifically, when the adjusting roller 3343 contacts the guide mold 483, it will push and apply force to the pipe to complete the embossing. The gap between the two guide molds 483 corresponds to the two ridges on the pipe, that is, the unembossed area.

[0066] As a preferred embodiment, the first elastic pin 332 and the electromagnet 335 used for the one-way clamping in embodiment 1 can be eliminated in embodiment 2, and the rib pressing module only needs to be close to the surface of the pipe under the action of the first elastic component.

[0067] The above is only a preferred embodiment of the present application and does not impose any form of limitation on the present application. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present application shall fall within the scope of protection of the present application.
