Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the utility model provides a three-way pipe forming machine for ejecting a side pipe orifice 11 of an everted water pipe 1, the three-way pipe forming machine comprises a clamping device 2 for limiting the movement of the water pipe 1, an ejection mechanism 3 corresponding to the clamping device 2 and a moving device 4, the ejection mechanism 3 is inserted into the water pipe 1 through the moving device 4;

the ejection mechanism 3 comprises an ejector rod 31 mounted on the moving device 4 and a swinging member 32 hinged to the ejector rod 31, wherein a spherical portion 321 is arranged at one end of the swinging member 32, and the spherical portion 321 is turned to the ejection channel 211 after contacting with the pressure-bearing arc-shaped surface 221 so as to eject the side pipe orifice 11 into a tubular shape. It should be noted that 1/2, which is the difference between the inner diameter of the protruding channel 211 and the diameter of the spherical portion 321, is the wall thickness stretching value, so when the side nozzle 11 is ejected to form the flange, the flange can be more attached to the inner wall of the protruding channel 211, so as to form a round nozzle without affecting the ejection of the flange. The wall thickness of the water pipe to be processed is smaller than the wall thickness stretching value, and preferably, the wall thickness of the water pipe to be processed is 0.95-0.99 of the wall thickness stretching value.
Specifically, the clamping mold 21 includes a bottom mold 212 and a top mold 213 matched with the bottom mold 212, a water pipe cavity 214 matched with the water pipe 1 is formed between the top mold 213 and the bottom mold 212 in a closed manner, and the pressure-bearing member 22 is installed in the water pipe cavity 214. The three-way pipe forming machine further comprises a die opening device 5 used for controlling the opening and closing of the clamping die 21, wherein the die opening device 5 comprises a clamp 51 used for clamping and fixing the bottom die 212 and a lifting device 52 connected with the top die 213. The pressure-bearing part 22 comprises a pressure-bearing rod 222 matched with the water pipe 1 and a handle 223 for holding, the pressure-bearing arc-shaped surface 221 is arranged at one end of the pressure-bearing rod 222, and the other end of the pressure-bearing rod 222 is connected with the handle 223. Therefore, the lifting and lowering of the top mold 213 can be controlled by the lifting and lowering device 52, and the opening and closing of the clamp mold 21 can be controlled. Preferably, the clamp is a bench clamp, and the lifting device is a hydraulic lifting device or a pneumatic telescopic device.
In order to facilitate the water pipe 1 to be mounted on and dismounted from the pressure-bearing rod 222, the bottom die 212 is provided with a fixing shaft 215 for mounting the pressure-bearing member 22, and the pressure-bearing rod 222 is provided with a mounting hole (not shown) adapted to the fixing shaft 215. Therefore, when the water pipe 1 needs to be taken out or put into the pressure-bearing rod 222, the handle 223 is pushed to turn the end of the pressure-bearing rod 222, which is provided with the water pipe 1, to the side of the user, so that the processed water pipe can be taken out conveniently, and the water pipe to be processed is arranged to prepare for the next processing operation.
In terms of driving the ejection mechanism 3, the moving device 4 includes a guide rail 41, a moving base 42 mounted on the guide rail, and a driving device 43, and the driving device 43 drives the moving base 42 to move along the guide rail 41, so as to control the insertion or extraction of the ejection mechanism 3 into or out of the water pipe 1. Preferably, the driving device 43 is a hydraulic telescopic device, which is a prior art and will not be described herein.
The horizontal plane in which the spherical center of the spherical part 321 rotates around the ejector rod 31 needs to coincide with the axis of the ejecting channel 211, so as to avoid destructive deformation of the hinge joint of the spherical part 321 and the ejector rod 31 caused by hard collision between the spherical part 321 and the inner wall of the ejecting channel 211 during ejecting and flanging. Therefore, the installation angle of the ejector mechanism 3 is conveniently determined to ensure that the horizontal plane in which the center of the sphere of the spherical portion 321 rotates about the ejector pin 31 coincides with the axis of the ejecting passage 211. The moving base 42 is provided with a clamping block 421 for clamping and fixing the ejector rod 31. The moving base 42 is provided with a limiting rod 6 for limiting the installation angle of the ejection mechanism 3, and the ejector rod 31 is provided with a positioning column 7 corresponding to the limiting rod 422. The clamping block 421 comprises an upper clamping block 4211 and a lower clamping block 4212, and the upper clamping block 4211 and the lower clamping block 4212 are provided with arc-shaped openings corresponding to each other so as to clamp the ejector rod 31. The upper clamping block 4211 and the lower clamping block 4212 are connected through a bolt connection mode. Therefore, when the ejection mechanism 3 needs to be replaced or the installation angle of the ejection mechanism 3 needs to be adjusted, the connected bolts are loosened. Meanwhile, the preset installation angle of the ejector rod 31 can be limited by the limiting rod 6, namely, the installation angle of the ejection mechanism 3 is determined by the collision between the limiting rod 6 and the positioning column 7 and is the preset installation angle.
Further, in order to make the ejector mechanism 3 capable of finely adjusting the mounting angle of the ejector mechanism 3 according to actual mounting and use conditions, the moving base 42 is provided with an adjustment base plate 61 for adjusting the amount of extension of the stopper rod 6, and the stopper rod 6 is provided with a threaded portion for threaded connection with the adjustment base plate 61. Therefore, the limit rod 6 can be screwed to control the extending amount of the limit rod 6, and the installation angle of the ejection mechanism 3 when the limit rod 6 abuts against the positioning column 7 is changed.
On the other hand, when a worker inserts the water pipe 1 into the pressure-bearing rod 222, the worker usually needs to align the side pipe opening of the water pipe 1 with the top-extending channel 211, because the manual insertion generally has a certain error, and when the worker intentionally adjusts the position relationship between the side pipe opening 11 and the top-extending channel 211, the production efficiency is relatively reduced, so the pressure-bearing rod 222 is in clearance fit with the water pipe 1, so that the water pipe 1 can rotate relative to the top rod 31 under the action of external force. Therefore, when the overlap ratio between the side nozzle 11 and the protruding channel 211 is within a certain range, the side nozzle 11 rotates during the process of being pushed out and flanged by the spherical part 321, so that the side nozzle 11 is gradually aligned with the protruding channel 211.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
