Referring to Fig. 3, the tee of the present invention has two parallel branch pipes in the same direction and a main pipe opposite to the direction of the branch pipes. The roots of the two branch pipes are connected to form a U shape. 2 transported to the feed port of the three-way feed plate 5 of the sliding collar mechanism, and enters the support frame from the three-way feed port (see Figure 3 for the structure of the support frame). The rotary vibrating plate is a kind of feeding equipment with automatic orientation and sorting. When the rotary vibrating plate is working, a continuous force of a certain frequency is applied to the plate to make it vibrate at high speed, high frequency and slight amplitude in the up and down and circumferential directions, and throw the workpiece obliquely. Moving forward, there is usually a specific inclined track designed on the periphery of the material tray, so that the workpiece in the material tray moves to a higher place gradually, during which, the U-shaped tee with an incorrect direction rides on the vibrating plate with the vibration of the vibrating plate On the track, it will fall back into the hopper after reaching a certain position, so that the disordered U-shaped tees are automatically and orderly arranged in an orderly manner and accurately transported to the next process. The three-way chute connects the outlet of the three-way rotating vibrating plate 1 and the feed port of the three-way feeding plate 5. Specifically, the high end of the chute is connected to the discharge port of the vibrating plate, and the low end is connected to the tee of the sliding collar mechanism. The corresponding position of the feeding port is coordinated so that the tee comes out from the outlet of the vibrating plate and enters the support frame through the chute. In the same way, the welding rings in the welding ring rotating vibration plate 3 are arranged in an orderly manner, divided into two rows and enter the arc-shaped welding ring chute 4, and one by one in the welding ring chute 4 and the drop ring of the collar mold Arranged in the groove 8, when the welding ring 11 in the welding ring part 33 of the collar through hole is put on the tee and taken away, the welding ring at the bottom of the drop ring groove 8 falls into the welding ring part 33, The welding ring stop piece 12 is an effective measure to ensure that the welding ring remains in the welding ring portion 33 and prevent the welding ring 11 from falling off from the welding ring portion 33 . As shown in Figure 2, one end of the welding ring stop piece 12 is fixed on the side wall of the collar mold with a screw 13, the other end is a free end, and the free end extends to the opening direction of the collar through hole in the side wall and extends into the welding ring. The ring portion stops the upright welding ring within the opening range of the side wall of the collar mold. Welding ring stop piece 12 is a metal elastic thin sheet, when the tee that puts on welding ring is pushed out from the through hole of the collar by the needle bar, the free end of welding ring stop piece 12 is bent and deformed outwards at the same time. The pipe can be smoothly withdrawn from the through hole of the collar and leave through the discharge port of the workbench (the discharge port is not shown in the figure). The new tee to be processed enters the support frame from the tee chute 2, and starts the next round of collaring process. This cycle is repeated, and the welding ring of the tee pipe sleeve is continuously and efficiently processed.

See Fig. 2, be provided with tee positioning block 14 on the side wall of described collar mold, described tee positioning block is arranged between the opening of two welding ring parts, the arc-shaped outer wall of described tee positioning block and three-way positioning block The shape of the connecting root of the two branch pipes of the pass is adapted, so that the tee is positioned and clamped together with the support frame. When the tee is pushed into the through hole of the collar by the support frame, the connecting roots of the two pipes move toward the tee positioning block 14 until they reach the tee positioning block. The insertion depth in the through hole of the collar plays an accurate role in positioning the fixed size of the welding ring.

Referring to Fig. 3 and Fig. 4, the support frame 25 is provided with a three-way card cavity 34 and a mandrel cavity 35, and the sliding collar mechanism also includes a slide rail (not shown), a mandrel plate 27, and a support frame Fixed plate 26, the slide rail is located between the workbench 10 and the bracket fixed plate 26, the bracket fixed plate 26 is directly installed on the slide rail, the bracket fixed plate 26 is fixedly installed with the bracket 25 , the middle part of one end of the support frame 25 is provided with a concave three-way card cavity 34, which can accommodate the main pipe of the three-way card cavity and the root of the branch pipe connected to the main pipe. The main pipe is inserted into the mandrel cavity 35, and the mandrel plate 27 is connected to the piston rod of the hydraulic cylinder 7, and the mandrel 24 is fixed on the mandrel plate, and the mandrel 24 can slide along the mandrel cavity 35. The mouth is facing the mandrel, the root of the branch pipe and the outer wall of the two pipes connecting the root are surrounded by the groove wall in the three-way clamping cavity, the rod head of the mandrel is close to the three-way clamping cavity, and the root of the mandrel is fixed on the mandrel plate 27, the mandrel plate 27 is connected to the piston rod of the hydraulic cylinder, and a main spring 23 is arranged between the support frame and the mandrel plate. The function of the sliding collar mechanism is to transmit the stroke of the piston rod of the hydraulic cylinder to the support frame through the mandrel plate, so that the support frame slides to the collar die, thereby inserting the tee into the through hole of the collar.

As shown in Figure 3, the head of the mandrel is a bell-mouth structure. When the bracket leans against the ring die and the connecting roots of the two branch pipes of the tee abut against the outer wall of the tee positioning block 14, the hydraulic cylinder The piston rod continues to advance to make the main spring 23, and now the mandrel 24 will be inserted into the main pipe of the tee and expand the main pipe to form a bell mouth. Because limit through holes are all set on the support frame and the mandrel plate, and limit pull rods 31 are arranged in the two limit through holes. The maximum distance between the support frame and the mandrel plate can be controlled, and the insertion depth of the mandrel 24 can be adjusted by controlling the maximum distance between the support frame and the mandrel plate, that is, the size of the bell mouth of the three-way main mouth can be adjusted.

When the piston rod moves to the right, the elastic potential energy of the main spring makes the mandrel plate and the bracket far away, and the pull rod 31 between the two plates can keep the distance between the two within a certain range. One end of the pull rod 31 can also be fixed on the bracket, and the other end can move through the corresponding limiting through hole on the mandrel plate 27 and be limited by a nut.

A material stripping needle bar 21 is slidably arranged inside the collar portion of the through hole of the collar, and one end of the stripping needle bar is fixed on the stripping plate 22, and an interlocking push plate 28 is also fixed on the stripping plate. The push plate is provided with a material return avoidance groove, and a cross bar 29 is inserted in the material return avoidance groove, and the cross bar is fixed on the support frame. A secondary spring 30 is provided between the stripper plate 22 and the template 20 .

When the stripping plate 22 is attached to the template 20, the stripping needle bar is inserted into the collar mold cavity, and when the support frame moves to the left, the cross bar 29 can move to the left in the stripping avoidance slot until it reaches the stripping space. When avoiding the left end of the empty groove, the cross bar 29 pushes the push plate 28 to move to the left, so that the stripping plate 22 drives the stripping needle bar to gradually leave the cavity of the collar mold, and the space is avoided so that the tee branch can be inserted into the collar mold (three The branch pipe passes through the welding ring first, and the welding ring is a split ring. When the branch pipe of the tee passes through, the ring opening of the welding ring will be opened, and the welding ring will clamp the branch pipe to form an interference fit relationship between the two). When returning material, the bracket first moves to the right under the drive of the hydraulic cylinder, and the cross bar 29 moves in the material withdrawal avoidance groove. The plate 28 moves to the right, so that the stripping plate 22 drives the stripping needle bar to eject the tee in the collar mold cavity, and completes the stripping process. The function of the auxiliary spring 30 is to make the stripping plate 22 leave the template 20 when the device is in the process of stripping, so that the stripping needle bar is pulled away from the collar through hole for a certain distance, and the space is made to make the drop ring groove 8 The lowermost welding ring falls into the welding ring part 33, and prepares for entering the collar processing work of the next three-way pipe fitting.

Referring to Fig. 5, in order to improve the working efficiency and make the tee enter the three-way card cavity 34 on the support frame 25 from the three-way rotating vibrating plate 1 in time to be correctly positioned, the present invention makes a further improvement on the basis of the above-mentioned collar device. Improvements, specifically:

The lower surface of the three-way feeding plate 5 is pasted with elastic rubber block 36, and the lower wall of the elastic rubber block interferes with the pipe wall of the three-way. Although the connection has a tendency to move forward, the elastic rubber block 36 overcomes the friction between the tee and the bracket, and prevents the tee from moving forward, so that the tee enters the tee card cavity 34 in the bracket. The wall surface at the root of the branch pipe is close to the groove wall in the three-way card cavity, so that the three-way card is positioned in the three-way card cavity in time. When the support frame continues to move to the ring die, the support frame transmits thrust to the tee, the elastic rubber block is deformed by force, and the tee pushes the elastic rubber block away and moves forward until the connecting root of the two branch pipes of the tee reaches the three-way joint. Pass through positioning block 14 till.
