BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 It is an overall structure perspective schematic view of an embodiment of the utility model. DETAILED DESCRIPTION

[0014] The utility model will be further described below with reference to the drawings.

[0015] As shown in the drawings Figure 1 The utility model discloses a kind of air conditioner pipe continuous positioning clamping necking device, including storage tank 1, the storage tank 1 is arranged and stacked with several pipe materials 2 from bottom to top in it, the bottom discharge port of the storage tank 1 is below being provided with guide groove 3;A certain amount of pipe material is stored in advance in storage tank, with the continuous of necking processing, multiple pipe materials are sequentially dropped into the guide groove below from the bottom discharge port.

[0016] The guide groove 3 is provided with pusher mechanism near one end of the storage tank 1, the pusher mechanism pushes pipe material 2 below the storage tank 1 and moves along the guide groove 3, the side of the storage tank 1 away from the pusher mechanism is provided with pressing mechanism, for pressing the pipe material 2 at the end of the guide groove 3 away from pusher mechanism;Pipe material is pushed to preset necking station along guide groove by pusher mechanism each time, pipe material is fixed by pressing mechanism, to facilitate necking processing, avoid the movement of pipe material and affect the accuracy of necking.

[0017] The end of the guide groove 3 away from pusher mechanism is moved close to being provided with necking forming die 7, and the necking forming die 7 is provided with discharge chute 8 between the guide groove 3. By the axial direction of necking forming die approaching pipe material and pressing on the port of pipe material, to form a section of expected necking structure on the port of pipe material.

[0018] In the process, the pushing distance of the pushing mechanism is used to control the positioning of the pipe material, determine the position of the pipe material necking, and then the pressing mechanism is used to press and fix the pipe material pushed to the position. Finally, the advancing distance of the necking forming die 7 is controlled to control the length size of the pipe end necking, so as to realize the precise positioning and forming of the pipe end necking. After the necking processing of a pipe material is completed, the necking forming die 7 and the pressing mechanism are retreated to make the processed pipe material in a free state, the pushing mechanism is retreated to make the new pipe material fall into the groove, and the above steps are repeated to complete the necking processing of the new pipe material again. In the process of pushing the pipe material to the processing position, the necked pipe material is pushed and falls into the discharging groove, so as to realize automatic continuous positioning and clamping, ensure efficient necking processing, and ensure the precision of each pipe necking processing.

[0019] The pushing mechanism is provided with a push rod 4 which is movably arranged along the guide groove 3. The outer diameter of the push rod 4 is consistent with the outer diameter of the pipe material 2, and the guide groove 3 is a semicircular cross-section groove which is adapted to fit the pipe material 2.

[0020] The push rod can keep relative fitting with the guide groove during pushing the pipe material, which can ensure the stability of pushing and avoid the disengagement of the pipe material from the guide groove. After the bottom layer of the stacked pipe material is completely pushed out, the push rod can replace the bottom layer of the pipe material to support the upper layer of the pipe material. The groove type of the guide groove limits the pipe material in the radial direction, so that the port of the pipe material can be accurately aligned with the necking forming die 7 after the pipe material is pushed to the position along the guide groove, to avoid large necking forming error caused by eccentricity.

[0021] The end surface of the push rod 4 is fixedly provided with a support rod 5, and the push rod 4 drives the support rod 5 to be inserted and matched with the inner hole of the pipe material 2. By arranging the support rod, the inner support of the pipe material is realized, which can avoid the deformation of the pipe wall caused by overpressure during axial pressing. The inner support can further limit the pipe material in the radial direction, which can further ensure the accurate alignment of the port of the pipe material with the necking forming die 7. In addition, since the outer diameter of the support rod is smaller than the outer diameter of the push rod, the new pipe material falls from the push rod to the support rod during the resetting of the push rod, and then falls into the guide groove, realizing staged feeding and buffering the feeding.

[0022] The necking forming die 7 is provided with a cavity, an inner wall of the cavity is provided with a tapered forming surface, and the support rod 5 is provided with a tapered support surface parallel to the forming surface. With the necking forming die 7 approaching the pipe material port and sliding along the inner wall forming surface of the cavity, the necking effect is achieved, and after being completely pressed into position, the necking forming die just presses the necking section of the pipe material on the tapered support surface at the end of the support rod, thereby further improving the forming precision of the necking structure on the basis of stamping forming.

[0023] The pressing mechanism is provided with a pressing block 6, and one side end face of the pressing block 6 is flush with the port of the guide groove 3. When the pipe material is fed, the pipe material is pushed by the push rod until the pipe section of the pipe end to be machined extends out of the port of the guide groove, at which time the part of the pipe material not extending out of the guide groove is pressed in the groove by the pressing block 6, and then the necking forming die 7 is driven to approach the pipe end in the axial direction for necking machining. The end face of the pressing block flush with the guide groove plays an axial limiting role on the necking forming die, so as to avoid the precision error caused by over-pushing. In addition, a distance measuring sensor can be arranged on the end face of the pressing block, and the distance between the necking forming die 7 and the pressing block 6 can be detected only when the pipe material is pressed by the pressing block. Through the distance measuring signal feedback, it can be judged whether the pipe material is pressed by the pressing block and whether the necking forming die 7 is stamped into position, so as to comprehensively control the pushing stroke of the necking forming die 7, thereby further ensuring the necking forming precision.

[0024] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
