[0041] Preferably, the bottom of the support block 14 is connected to the surface of the processing table 201 through a return spring 13, one end of the first connecting rod 12 is fixedly connected to the support block 14, the other end of the first connecting rod 12 is movably connected to the connecting piece 11, one end of the reciprocating cam 10 is movably connected to the driving rod 8, and the other end of the reciprocating cam 10 is movably connected to the connecting piece 11.

[0042] Preferably, the groove pressing device 9 includes: a U-shaped bracket 21, the bottom of the U-shaped bracket 21 is connected to the table top of the processing table 201 through a support column 20, a groove mother seat 22 is installed in the U-shaped groove of the U-shaped bracket 21, and an avoidance groove 32 is provided on the groove mother seat 22, a guide groove 25 is provided on the inner wall of the U-shaped end of the U-shaped bracket 21, and a return spring 23 is installed in the guide groove 25.

[0043] Preferably, identical guide heads 24 are fixedly provided at both ends of the pressing piece 28 , and the guide heads 24 are movably extended into the guide groove 25 , one end of the return spring 23 is fixedly connected to the guide head 24 , and the other end of the return spring 23 is fixedly connected to the bottom of the inner wall of the guide groove 25 .

[0044] Preferably, two identical groups of guide rods 31 are symmetrically fixed on the top of the guide head 24, and each group of guide rods 31 is sleeved with a return spring three 30, the connecting block 29 is slidably connected to the guide rods 31 up and down, and one end of the return spring three 30 is fixedly connected to the connecting block 29, and the other end of the return spring three 30 is fixedly connected to the pressing piece 28.

[0045] Preferably, the bottom of the third connecting rod 26 is fixedly connected to the connecting block 29 , the top of the third connecting rod 26 is fixedly provided with a fixing block 27 , and the counterweight plate 19 is installed between two sets of fixing blocks 27 .

[0046] The working principle and beneficial effects of the above scheme are as follows: when in use, the bevel gear 15 is controlled to rotate by starting the driving motor 4, and the bevel gear 15 drives the driving rod 8 to rotate through the bevel gear 27, and then drives the connecting piece 11 to swing through the reciprocating cam 10. While the connecting piece 11 swings, the support block 14 is driven by the first connecting rod 12 to achieve up and down reciprocating movement. When the support block 14 moves downward, the fixed block 27 is pulled downward by the second connecting rod 17 and the U-shaped connecting piece 18, and the fixed block 27 is pushed by the third connecting rod 26 to move downward along the outer wall of the guide rod 31 and compress the return spring 3 30. In this process, the pressing piece 28 moves downward along the guide groove 25 through the guide head 24, and presses the end of the seamless steel pipe placed in the groove mother seat 22, and when the connecting block 29 fully compresses the return spring 3 30, the downward pressure also reaches the maximum. In this process, the end of the seamless steel pipe will form the required groove, and the setting of the counterweight plate 19 also provides sufficient downward pressure for pressing.

[0047] It should be noted that if Figure 2 As shown in, during the pressing process, the end A of the seamless steel pipe fitting is first processed by the first group of groove pressing devices 9 to form a groove and then continues to move forward until it moves to the second group of groove pressing devices 9. The tail B of the seamless steel pipe fitting is just located in the first group of groove pressing devices 9. At this time, the end A of the seamless steel pipe fitting located in the second group will be pressed again to ensure the processing accuracy. After the tail B of the seamless steel pipe fitting located in the first group is pressed for the first time to form a groove, the seamless steel pipe fitting moves to the second group of groove pressing devices 9. An assembly line is formed in the above manner, and the two ends of each group of seamless steel pipe fittings can be repeatedly pressed twice to improve the processing accuracy.

[0048] The structures of the groove female seat 22 and the pressing member 28 are not limited to Figure 2 and Figure 3 The U-shaped structure shown in the figure, the groove mother seat 22 and the pressing piece 28 can be replaced according to the required groove angle and shape. And each group of groove pressing devices 9 is provided with two groups of groove mother seats 22, which can not only process special-shaped grooves, but also when a single groove is required, the groove mother seat 22 in one group of U-shaped brackets 21 can be removed, and the seamless steel pipe will not be compressed when passing through the group of U-shaped brackets 21. Through the two groups of groove processing units 202 arranged symmetrically, the number of groove mother seats 22 reaches four groups, and the number and shape of the four groups of groove mother seats 22 can be changed at will, so as to achieve different processing effects.

[0049] In order to improve the pressing effect and the forming accuracy of the groove, the groove mother seat 22 in the first group of groove pressing devices 9 can be slightly larger than the opening of the groove mother seat 22 in the second group of groove pressing devices 9. For example: now the slope size of the two ends of the seamless steel pipe fitting is required to be 70°. At this time, the groove mother seat 22 in the first group of groove pressing devices 9 can be set to 75°, and the groove mother seat 22 in the second group of groove pressing devices 9 can be set to 70°. In this way, when the end A of the seamless steel pipe fitting is pressed for the first time by the first group of groove pressing devices 9, it can be shaped, and then it reaches the required size when it is pressed by the second group of groove pressing devices 9. This greatly improves the processing accuracy.

[0050] Example 3

[0051] Based on any one of Examples 1-2, please refer to Figure 1 and Figure 5 The pipe collection assembly 3 includes: a support frame 33, on which a plurality of conveying rollers 34 are movably mounted, a pneumatic push rod 35 is mounted on the top of one side of the support frame 33, a guide support 42 is mounted on the other side of the support frame 33, a pulley seat 36 is mounted on the bottom of the end of one end of the guide support 42 through a fixing block 2 38, and the other end of the guide support 42 is surrounded by two groups of side baffles 41 to form a blanking cavity 44, a vertical rod 43 is fixed in the blanking cavity 44, and two groups of side baffles 41 are symmetrically fixed on the outer walls of both sides of the guide support 42, the two groups of side baffles 41 and the guide support 42 form a U-shaped guide groove structure, and the buffer cart 40 is movably arranged In the guide groove structure, the buffer trolley 40 extends obliquely upward to form a pipe baffle 39, the fixed pulley 37 is rotatably connected to the pulley seat 36, the sprocket support 46 is installed on the bottom of the guide support 42 by bolts, and a chain 47 is installed on the sprocket in the sprocket support 46, and a counterweight block 48 is fixedly connected to the bottom of the chain 47. One end of the connecting rope 45 is fixedly connected to the buffer trolley 40, and the other end of the connecting rope 45 is wrapped around the fixed pulley 37 and fixedly connected to the chain 47. The feeding port of the collecting rack 50 is set below the blanking cavity 44, and a plurality of groups of anti-collision seats 49 are installed on the collecting rack 50, and the plurality of groups of anti-collision seats 49 are arranged in sequence from high to bottom.

[0052] Preferably, the fixed pulley 37 is a pulley with a damping effect.

[0053] Preferably, a avoidance groove matching the bent portion of the tail of the guide support 42 is provided at the bottom of the buffer trolley 40 .

[0054] Preferably, a bidirectional damping sprocket is mounted on the sprocket support 46 .

[0055] Preferably, the collecting rack 50 is provided with running wheels at the bottom for movement.

[0056] The working principle and beneficial effects of the above scheme are as follows: the pipes processed by the double-head reciprocating processing assembly 2 are transmitted to the conveying roller 34, and after being conveyed to the same position as the guide support 42 by the conveying roller 34, the pneumatic push rod 35 is started and pushes the pipes to move to the pipe baffle 39 of the buffer trolley 40, and the buffer trolley 40 slides along the downwardly inclined guide support 42. At this time, the buffer trolley 40 moves by pulling the chain 47 through the connecting rope 45. Since the fixed pulley 37 and the sprocket on the sprocket support 46 have a damping effect, the buffer can be slowed down. The moving speed of the trolley 40 is slowed down, and the counterweight block 48 arranged under the chain 47 can also help slow down the moving speed of the buffer trolley 40. Since the bottom of the buffer trolley 40 is provided with an avoidance groove matching the bend at the tail of the guide support 42, when the buffer trolley 40 carries the pipe to the tail of the guide support 42, it will deflect and abut against the pipe baffle 39 through the vertical rod 43, so that the pipe naturally falls onto the anti-collision seat 49 and rolls along several groups of anti-collision seats 49 into the collection rack 50 to complete storage. When the collection rack 50 is full, the collection rack 50 can be pushed for conversion.

[0057] Among them, the vertical rod 43 is set to ensure that the rotation angle of the buffer trolley 40 remains within a fixed range to prevent the buffer trolley 40 from falling, and when the pipes on the buffer trolley 40 are transported, the counterweight block 48 will naturally fall back, thereby driving the buffer trolley 40 to reset, and the weight of the counterweight block 48 can be replaced according to the size of the pipe. The setting of several groups of anti-collision seats 49 can protect the pipes.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
