[0002] There is a pipe fitting 80, such as Figure 1 As shown, the pipe fitting 80 has a through flow hole 801, one end of the pipe fitting 80 is bent 90°, and the inner hole wall of the other end of the pipe fitting 80 has an annular installation groove 802 for installing a sealing ring, and the annular installation groove 802 is close to the bending part. In order to upset the annular installation groove 802 or the conical surface inside the pipe fitting 80, a heading machine 90 is required. When the heading machine 90 is used to form the pipe fitting 80, the loading and unloading of the pipe fitting 80 mostly needs to be placed manually, which has high labor costs and low work efficiency.

[0003] In view of this, our company currently has a pipe end forming equipment that can automatically load and unload materials, such as Figure 2 As shown, it includes a heading machine 90, a workbench 91, a manipulator 92, a loading platform 93 and a unloading belt 94. The workbench 91 is located between the heading machine 90 and the loading platform 93, and the unloading belt 94 is located on the side of the loading platform 93 away from the workbench 91. The manipulator 92 reciprocates between the unloading belt 94 and the workbench 91, and the workpiece is moved from the loading platform 93 to the workbench 91 by the manipulator 92. It should be pointed out that after the workpiece is placed on the workbench 91, the workpiece is clamped on the workbench 91. When the heading machine 90 processes the workpiece, the manipulator 92 needs to move toward the loading platform 93 to avoid interfering with the movement of the clamping device on the workbench 91. After the workpiece is upset, the manipulator 92 grabs the processed workpiece and drops it to the unloading belt 94, and then the manipulator 92 grabs and moves the workpiece to the workbench 91. However, in the above embodiment, since only one robot 92 is used, except for the first time placing the workpiece, before placing the new workpiece on the workbench 91, the processed workpiece needs to be moved to the unloading belt 94. When the unloading belt 94 is far away from the workbench 91, the interval time for placing the new workpiece on the workbench 91 again is long, and the efficiency is low.

[0031] Application Overview

[0032] The existing tube end forming equipment only uses one robot. Except for the first time placing the workpiece, before placing the new workpiece on the workbench, the processed workpiece needs to be moved to the unloading belt. When the unloading belt is far away from the workbench, the interval time for placing the new workpiece on the workbench again is long, and the efficiency is low.

[0033] Based on the above technical problems, the present application proposes a tube end forming device, wherein the tube end forming device has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the tube end forming device provided by the present application is easy to produce and low-cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0034] Schematic tube end forming equipment,

[0035] refer to Figures 3 to 5 According to a preferred embodiment of the utility model, a tube end forming device is provided. Figure 3 and Figure 4 As shown, the invention comprises a base 10, a heading machine 20, a workbench 30 and a material grabbing assembly 40, which is used for processing including but not limited to Figure 1 The pipe fitting 80 shown in the figure has a through flow hole 801, one end of the pipe fitting 80 is bent 90°, and the inner hole wall of the other end of the pipe fitting 80 has an annular mounting groove 802 for mounting a sealing ring, and the annular mounting groove 802 is close to the bend.

[0036] Specifically, Figure 3As shown, the base 10 is provided with a plurality of trays 101 for placing pipe blanks.

[0037] In addition, if Figure 3 As shown, the heading machine 20 is arranged at one side of the material tray 101, and the annular mounting groove 802 is upset on the inner hole wall of the pipe blank by the heading machine 20.

[0038] In addition, if Figure 4 As shown, the workbench 30 is located between the material tray 101 and the heading machine 20 , and the workbench 30 includes a lower die 301 . It should be noted that the pipe blank is placed on the lower die 301 of the workbench 30 during processing.

[0039] In addition, if Figure 3 As shown, the material grabbing assembly 40 includes two mechanical grippers 401 arranged at intervals, and the two mechanical grippers 401 are slidably disposed on the base 10 in the length direction of the base 10, and the two mechanical grippers 401 are liftably disposed on the base 10 in the height direction of the base 10.

[0040] More specifically, in order to realize the up-down movement and left-right movement of the mechanical gripper 401, as shown in FIG. Figure 3 As shown, the material grabbing assembly 40 further includes a first linear module 402, a second linear module 403 and a connecting seat 404. The first linear module 402 and the second linear module 403 are arranged vertically. More specifically, the first linear module 402 is arranged horizontally on the base 10, and the second linear module 403 is arranged vertically on the base 10. The connecting seat 404 is fixedly connected to the slider of the second linear module 403 and moves with it. The two mechanical grippers 401 are fixedly mounted on the connecting seat 404 and spaced a predetermined distance apart. When the first linear module 402 is in motion, the two mechanical grippers 401 move in the length direction of the base 10, and when the second linear module 403 is in motion, the two mechanical grippers 401 move in the height direction of the base 10.

[0041] It should be noted that, assuming that the pipe blank is not placed on the lower die 301 at this time, the two mechanical clamps 401 move downward a predetermined distance and grab the two pipe blanks, and the two mechanical clamps 401 are moved toward the workbench 30. At a certain moment, one of the mechanical clamps 401 is located directly above the lower die 301. By moving the two mechanical clamps 401 downward, the pipe blank on the mechanical clamp 401 directly opposite to the lower die 301 is placed on the lower die 301, and then the pipe blank is processed by the heading machine 20. It should be noted that during the processing, one of the mechanical clamps 401 is empty, and the other mechanical clamp 401 still holds a pipe blank. After the processing of the pipe blank is completed, the processed pipe blank is clamped by the idle mechanical clamp 401, and the other pipe blank that has not been processed is placed on the lower mold 301 through another adjacent mechanical clamp 401; after the processing of this pipe blank is completed, the two processed pipe blanks are unloaded; it is obvious that compared with the prior art in which only one mechanical clamp 401 is set, before each new workpiece is placed, the complete unloading of the processed workpiece must be completed. If the unloading table is far away from the workbench 30, the interval time for placing the new workpiece is long and the work efficiency is low. In the embodiment of the present application, two manipulators are set to grab two pipe blanks at the same time, so that one pipe blank can be quickly placed in the other pipe blank after processing, which has the advantages of shorter interval time for placing new workpieces and higher efficiency.

[0042] In addition, if Figure 4 and Figure 5 As shown, the lower mold 301 has a mounting groove 3011, and the mounting groove 3011 is used to place the pipe blank. When the pipe blank is placed on the mounting groove 3011, the upper half of the side of the pipe blank is exposed.

[0043] Furthermore, in order to achieve the position restriction of the pipe blank placed on the lower die 301, it is prevented that when the heading machine 20 applies a force to the pipe blank, Figure 4 and Figure 5 As shown, the pipe blank is separated from the installation groove 3011, and the workbench 30 also includes an upper mold 302, which is movably arranged on the base 10 in the height direction of the base 10, and the upper mold 302 has a snap-fit ​​groove (not marked in the figure). When the lower mold 301 is located directly below the upper mold 302 and the upper mold 302 is in contact with the lower mold 301, the installation groove 3011 and the snap-fit ​​groove are spliced ​​to form a tubular cavity. When the pipe blank is placed in the tubular cavity, the side surface of the pipe blank is in contact with the cavity wall of the tubular cavity.

[0044] Furthermore, if Figure 4 and Figure 5 As shown, the lower mold 301 is slidably disposed on the base 10 in the width direction of the base 10. When the lower mold 301 slides, the lower mold 301 is located directly below the upper mold 302 or the moving path of the lower mold 301 and the mechanical clamp 401 are located on the same straight line. It should be noted that, by making the lower die 301 slide, the upper die 302 and the lower die 301 can be staggered in the width direction of the base 10. More specifically, when the pipe blank is placed on the mounting groove 3011 of the lower die 301, the upper die 302 and the lower die 301 are staggered in the width direction of the base 10. When the heading machine 20 is working, the lower die 301 slides to the bottom of the upper die 302. This also means that the two mechanical clamps 401 do not need to move after placing a pipe blank in the mounting groove 3011, thereby avoiding the interference problem between the mechanical clamps 401 and the upper die 302.

[0045] Furthermore, in order to further improve the rigidity and strength of the pipe blank during processing, Figure 4 and Figure 5 As shown, the workbench 30 further includes a supporting member 303 , which is slidably disposed on one side of the lower mold 301 . When the supporting member 303 slides, the supporting member 303 approaches or moves away from a notch at one end of the installation groove 3011 .

[0046] It should be noted that the support member 303 is further implemented as a push rod of a cylinder. Before the upper mold 302 is engaged with the lower mold 301, the push rod of the cylinder extends into the flow hole of the pipe blank and provides support for the pipe blank to prevent the upper mold 302 from crushing the pipe blank; when the mechanical clamp 401 grasps the pipe blank, the push rod of the cylinder disengages from the flow hole of the pipe blank.

[0047] Furthermore, in order to prevent the upper die 302 from tilting when pressing the pipe blank, Figure 5 As shown, the upper mold 302 also includes a plurality of guide columns 3021, and both the base 10 and the lower mold 301 have a plurality of guide holes 102. The guide holes 102 on the base 10 are located directly below the upper mold 301. When the upper mold 302 moves downward a predetermined distance and approaches the lower mold 301, the guide columns 3021 extend into the guide holes 102 on the lower mold 301 and the base 10 in turn.

[0048] It should be noted that the guide column 3021 is slidably disposed in the guide hole 102 to guide the lifting movement of the upper mold 302 .

[0049] Further, in order to realize the action of the heading machine 20, as Figure 3 and Figure 5 As shown, the heading machine 20 includes a linear drive device 201 and a heading mounting seat, and the heading mounting seat is provided with a plurality of assembly holes 2031 for mounting the heading. The linear drive device 201 is connected to the heading mounting seat, and the heading mounting seat is slidably arranged on the base 10 in the length direction of the base 10. When the push rod of the linear drive device 201 is actuated, the heading on the heading mounting seat approaches or moves away from the workbench 30.

[0050] More specifically, if Figure 3 and Figure 4 As shown, the heading mounting seat includes a base 202 and a sliding seat 203. The base 202 is slidably set on the base 10 in the length direction of the base 10 and is connected to the linear drive device 201. The sliding seat 203 is slidably set on the base 202 in the width direction of the base 10 through the structure of a wire rod slider, and the assembly hole 2031 is set on the sliding seat 203.

[0051] It should be noted that, in the embodiment of the present application, the sliding seat 203 is provided with five assembly holes 2031 arranged at intervals to meet the upsetting processing requirements of the pipe blanks with different profiles. The screw slider structure includes a screw, a slider, and a rotary drive motor. The screw is rotatably mounted on the base 202. The slider is connected to the screw by a spiral transmission. The rotating shaft of the rotary drive motor is fixedly connected to the screw. The sliding seat 203 is fixedly connected to the slider and moves with the slider. When the rotating shaft of the rotary drive motor rotates, the sliding seat 203 moves in the width direction of the base 10, and makes the upsetting head on the assembly hole 2031 face one end port of the pipe blank.

[0052] Furthermore, in order to facilitate the continuous grabbing of another pipe blank to be processed after the pipe blank to be processed on the material tray 101 is completely grabbed, as shown in FIG. Figure 3As shown, there are two material trays 101. After the pipe blanks on one material tray 101 are processed, the pipe blanks on the other material tray 101 can be grabbed. In addition, the two material trays 101 are slidably arranged on the base 10 in the width direction of the base 10 through a linear drive module, so that the mechanical clamp 401 can grab the pipe blanks after moving downward. The material tray 101 is fixedly connected to the slider on the corresponding linear drive module. When the linear drive module is activated, the material tray 101 follows and moves in the width direction of the base 10.

[0053] Further, to facilitate cutting, Figure 3 As shown, the tube end forming device further includes a lower hopper 50, which is located on the side of the material tray 101 away from the workbench 30. The two mechanical grippers 401 slide back and forth between the workbench 30 and the lower hopper 50. When the two pipe blanks on the two mechanical grippers 401 are processed, the two mechanical grippers 401 move toward the lower hopper 50, and at a certain moment, the two mechanical grippers 401 are located directly above the lower hopper 50, and the two mechanical grippers 401 are released, and the two processed pipe blanks fall into the lower hopper 50.

[0054] Further, protection is provided for the personnel loading the loading tray 101, such as Figure 3 As shown, the tube end forming device further includes a guardrail 60 , and the guardrail 60 is disposed on one side of the mechanical clamp 401 .

[0055] In summary, the tube end forming device according to the embodiment of the present application is explained, which provides the tube end forming device with advantages such as shorter interval time for placing new workpieces and higher efficiency.

[0056] It is worth mentioning that in the embodiment of the present application, the tube end forming device has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the tube end forming device provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
