Detailed Embodiment

[0026] In order to enable those skilled in the art to better understand the technical solution of the utility model, the following further detailed description of the utility model is provided in conjunction with the specific embodiments.

[0027] The prior art CN201610900169.1 discloses a ferrule mechanism before welding, which is used to sleeved a copper ring on a copper pipe fitting to be welded, including a feeding component for transporting the copper ring, a receiving table cooperating with the feeding component, a positioning component movably connected to the receiving table, a pushing ring component for pushing the copper ring onto the positioning component, and a clamping component for moving and clamping the copper pipe fitting. The lower end of the copper pipe fitting faces the copper ring. The clamping component includes a clamping member located above the receiving table, and a detection component for monitoring the height of the copper pipe sleeved on the copper pipe fitting is further connected between the clamping component and the receiving table.

[0028] In the above prior art, only one end of the copper pipe fitting needs to be sleeved with a copper ring, while both ends of the U-shaped joint need to be sleeved with copper rings. Obviously, the above prior art is not applicable to U-shaped joints. Moreover, the structure of the above prior art is very complex, and it is more inconvenient for manufacturing and maintenance.

[0029] As Figure 1 shown, the copper ring 101 needs to be sleeved on both ends of the U-shaped joint 100.

[0030] AsFigure 2 , Figure 3 As shown in Figure 3 , to solve the above technical problems and meet the requirement of sleeving copper rings 101 at both ends of the U-shaped joint 100, the present utility model provides a U-shaped copper pipe joint sleeving device, which includes a copper ring feeding mechanism for supplying the copper rings 101, a U-shaped joint feeding mechanism for supplying the U-shaped joints 100, and a sleeving mechanism for sleeving the copper rings 101 onto the two ends of the U-shaped joint 100;

[0031] The copper ring feeding mechanism includes a base plate 1, on which two copper ring chutes 2 for copper ring feeding are provided. The inlets of the two copper ring chutes 2 are respectively connected to a copper ring feeding device (the copper ring feeding device is generally a vibrating feeding tray, which can arrange the copper rings and convey them to the copper ring chutes 2, and the copper rings at the back push the copper rings in front to move forward), so that the copper rings are placed flat at the bottom of the copper ring chutes 2 and move from the inlet to the outlet of the copper ring chutes 2. In this embodiment, the two copper ring chutes 2 are arranged oppositely and are on the same straight line, and the material conveying directions of the two copper ring chutes 2 are opposite.

[0032] At the outlets of the two copper ring chutes 2, a sleeving die 3 is provided, and two sleeving holes 4 are opened on the sleeving die 3; the distance between the two sleeving holes 4 is the same as the distance between the two ends of the U-shaped joint 100; the sleeving holes 4 are divided into upper and lower sections, where the diameter of the upper section 41 is the same as the outer diameter of the copper ring 101, and the diameter of the lower section 42 is the same as the outer diameter of the end of the U-shaped joint 100; an inlet port 43 communicating with the outlet of the copper ring chute is opened on the sleeving die 3, so that the copper ring 101 enters the bottom of the upper section 31 of the sleeving hole 4 through the copper ring chute 2;

[0033] The U-shaped joint feeding mechanism includes a joint chute 6, the inlet of the joint chute 6 is connected to a joint feeding device, and a feeding mechanism is provided at the outlet, so that the two ends of the U-shaped joint 100 are arranged vertically downward in the joint chute and move from the inlet end to the outlet end of the joint chute 6; the feeding mechanism includes a feeding fork 7 for pushing the U-shaped joint 100 to the sleeving hole 4, and further includes a stabilizing fork 8 for clamping the U-shaped joint 100 to prevent the U-shaped joint 100 from tipping during the feeding process; it further includes a profiling die 5. When the feeding fork 7 pushes the U-shaped joint 100 to the sleeving hole 4, the U-shaped joint 100 can be blocked by the profiling die 5 so that the two ends of the U-shaped joint 100 just fall into the two sleeving holes 4 of the sleeving die 3;

[0034] The sleeving mechanism includes a pressing die 11 arranged above the sleeving die 3, and the pressing die 11 can be lifted and lowered to press the two ends of the U-shaped joint 100 into the copper ring 101. To avoid damaging the U-shaped joint 100, the pressing die 11 is made of plastic, and a pressing groove matching the shape of the bent part of the U-shaped joint 100 is opened on the pressing die 11.

[0035] The principle of the present utility model lies in: the copper ring feeding mechanism conveys the copper ring 101 and fixes the copper ring 101 at the bottom of the upper section 41 of the ferrule hole 4; then the U-shaped joint feeding mechanism conveys the U-shaped joint 100 to the upper part of the ferrule hole 4, and finally the ferrule mechanism presses down the U-shaped joint 100 so that its two end parts respectively pass through the two copper rings 101 and reach the bottom of the lower section 42 of the ferrule hole 4, thus completing the ferrule work.

[0036] It can be foreseen that the upper section 41 and the lower section 42 of the ferrule hole 4 are coaxially arranged. The depth of the upper section 41 of the ferrule hole 4 can be adaptively adjusted according to the preset height of the ferrule 101 on the end part of the U-shaped joint 100, and the depth of the lower section 42 of the ferrule hole 4 only needs to meet the depth of the pressing die 11 pressing down.

[0037] More specifically, the copper ring chute 2 and the joint chute 6 are arranged in parallel; the moving direction of the feeding fork 7 is perpendicular to the axial direction of the joint chute 6. The U-shaped joint feeding mechanism further includes a track perpendicular to the joint chute, and a slider that can slide back and forth along the track is arranged on the track; the feeding fork 7 is installed on the slider; a linear driving mechanism such as a cylinder 9 is also arranged on the slider; the driving direction of the linear driving mechanism is parallel to the joint chute 6; the stabilizing fork 8 is driven by the linear driving mechanism, and when the feeding fork 7 pushes the U-shaped joint 100 to the mold 5, the stabilizing fork 8 disengages from the U-shaped joint 100 under the drive of the linear driving mechanism.

[0038] The function of the feeding fork 7 is to push the U-shaped joint 100 from the outlet of the joint chute 6 to the ferrule hole 4 for ferrule. During the pushing process, in order to prevent the U-shaped joint 100 from tipping over, a stabilizing fork 8 is also provided in this embodiment. The purpose of the stabilizing fork 8 is to support the U-shaped joint 100. In order to avoid interference between the stabilizing fork 8 and the pressing die 11, when the pressing die 11 performs the ferrule work, the stabilizing fork 8 will disengage from the U-shaped joint 100 under the drive of the cylinder 9 to avoid the pressing die 11.

[0039] In some embodiments, the feeding fork 7 includes two fork rods on the left and right; when pushing the U-shaped joint 100, the two fork rods on the left and right respectively act on the two end parts of the U-shaped joint 100 to avoid one-sidedness during pushing.

[0040] In addition, in some embodiments, a card slot is provided on the stabilizing fork 8, and when pushing the U-shaped joint 100, the U-shaped joint 100 is located in the card slot; the stabilizing fork 8 is located above the feeding fork 7. When pushing the U-shaped joint, the U-shaped joint 100 is supported by the groove walls on both sides of the card slot in the card slot to avoid tipping over.

[0041] To avoid difficult blanking, the profiling die 5 is movable in this embodiment. After the collar is completed, the profiling die 5 will automatically retract. When the feeding fork 7 pushes the U-shaped joint 100, the profiling die 5 extends to form a clamping of the U-shaped joint 100 with the feeding fork 7 at the collar hole 4. Specifically, the profiling die 5 and the feeding fork 7 are arranged on the same straight line and move in opposite directions. The two are interlocked. When the feeding fork 7 feeds the material, the profiling die 5 also moves towards the collar hole 4. When the feeding fork 7 retracts, the profiling die 5 also retracts to avoid.

[0042] In addition, it can be foreseen that the width of the copper ring chute 2 is the same as the diameter of the copper ring 101; the width of the joint chute 6 is the same as the thickness of the U-shaped joint 100. So that the copper ring 101 and the U-shaped joint 100 can be arranged and conveyed in a preset manner.

[0043] To facilitate the replacement of the collar die 3 to adapt to workpieces of different models, an installation groove is provided on the base plate 1 at the outlet of the copper ring chute 2. The collar die 3 is embedded in the installation groove and fastened with bolts.

[0044] To achieve automatic blanking, it further includes a jet port 10 for blanking. The jetting direction of the jet port 10 is the same as the extending direction of the copper ring chute 2. After the profiling die 5 and the feeding fork 7 retract, the jet port 10 connected to compressed air blows air at the workpiece, so as to blow the workpiece out of the collar hole 4 to achieve automatic blanking. In addition, the height of the jet port 10 can be adjusted to find an optimal jetting angle.

[0045] The above is only the preferred embodiment of the present invention. It should be noted that the above preferred embodiment should not be regarded as a limitation of the present invention. The protection scope of the present invention should be subject to the scope defined by the claims. For those of ordinary skill in the art, without departing from the spirit and scope of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
