Each chamfering box 2 is provided with a chamfering assembly 3 on the side closest to each other. Two guide rods 11 arranged along the length of the base plate 1 are fixedly connected to the base plate 1. Guide grooves 21 corresponding to the guide rods 11 are formed on the lower side of the chamfering boxes 2. The chamfering boxes 2 are slidably connected to the base plate 1 through the guide grooves 21 and the guide plates. A moving assembly 4 is provided on the base plate 1 to drive the chamfering boxes 2 toward or away from each other.

[0033] Reference Figure 1 and Figure 2 A support seat 12 is provided between the chamfered boxes 2, which is vertical and parallel to the length direction of the base plate 1. The support seat 12 is fixedly connected to the base plate 1, and the cross-sectional shape of the upper side of the support seat 12 in the vertical direction is set to an arc shape that gradually sinks downward from both ends to the middle. A fixing component 5 for fixing the tube body is provided on the upper side of the support seat 12, and a lifting component 6 for lifting the tube body to the upper side of the support seat 12 is provided on one side of the base plate 1.

[0034] The pipe body on the ground is lifted to the support seat 12 by the lifting component 6, and the pipe body is fixed by the fixing component 5. At this time, the moving component 4 drives the chamfering box 2 to drive the chamfering component 3 to move toward the end of the pipe body. The guide rod 11 guides the chamfering box 2 through the guide groove 21 to facilitate chamfering of the pipe body.

[0035] Reference Figure 1 and Figure 2 The chamfering assembly 3 includes a vertical chamfering disk 31 located on the side of the chamfering box 2 near the support base 12. A chamfering blade assembly 32 is mounted on the side of the chamfering disk 31 near the support base 12. A horizontal second hydraulic cylinder 33 is installed in the chamfering box 2. A mounting ring 34 is sleeved and rotatably connected to the second hydraulic cylinder 33. The top of the mounting ring 34 is fixedly connected to the inner wall of the chamfering box 2. The telescopic rod of the second hydraulic cylinder 33 passes through the side wall of the chamfering box 2 and is fixedly connected to the axis of the corresponding chamfering disk 31.

[0037] The moving component 4 drives the chamfering box 2 to move toward the direction of the tube body, thereby coarsely adjusting the distance between the chamfering knife group 32 and the end of the tube body. The telescopic rod of the second hydraulic cylinder 33 extends or shortens and drives the chamfering disk 31 and the chamfering knife group 32 to move, thereby adjusting the chamfer length according to different tube bodies to improve applicability. During chamfering, the second motor 353 drives the second bevel gear 352 to drive the first bevel gear 351 to rotate. At this time, the second hydraulic cylinder 33 fixed to the first bevel gear 351 drives the chamfering disk 31 and the chamfering knife group 32 to rotate, which is convenient for chamfering the end of the tube body.

[0038] Reference Figure 1 and Figure 2 The moving component 4 includes a bidirectional screw 41 parallel to the length direction of the base plate 1 and rotatably connected to the base plate 1. The ends of the bidirectional screw 41 pass through the lower side of the chamfer box 2 and are threadedly connected to the chamfer box 2, and one end of the bidirectional screw 41 is installed with a third motor (not shown in the figure) fixedly connected to the base plate 1.

[0039] The third motor drives the bidirectional lead screw 41 to rotate and drives the chamfering box 2 to move toward or away from each other, thereby roughly adjusting the distance between the chamfering knife group 32 and the end of the pipe body to improve work efficiency.

[0040] Reference Figure 1 and Figure 2 The fixing assembly 5 includes two fixing plates 51 symmetrically arranged at the ends of the upper side of the support base 12. When the support base 12 is fixed to the tube body via the fixing plates 51, the fixing arrangement is arranged in an arc shape that gradually rises upward from the ends to the middle. At this time, the fixing plates 51 and the support base 12 in the vertical direction are spliced ​​together to form a ring. The ends of the fixing plates 51 away from the lifting assembly 6 are both rotatably connected to the upper side of the support base 12, and the upper side of the support base 12 is provided with a driving member 52 that drives the fixing plates 51 to rotate.

[0041] Reference Figure 2 and Figure 3 The drive member 52 includes a rotating shaft 521 that passes through the same end of the fixed plate 51 and is fixedly connected to the fixed plate 51. The rotating shaft 521 is rotatably connected to the upper side of the support base 12. A vertical gear 522 is sleeved and fixedly connected to one end of the rotating shaft 521. The lower side of the gear 522 engages with a horizontal rack 523 that is parallel to the width of the base plate 1. A first hydraulic cylinder 524 is provided at the end of the rack 523 that is away from the lifting assembly 6 and is horizontal and faces the rack 523. The telescopic rod of the first hydraulic cylinder 524 is fixedly connected to the end of the rack 523. A vertical mounting rod 525 is fixedly connected to the base plate 1. The end of the first hydraulic cylinder 524 that is away from the rack 523 is fixedly connected to the side wall of the mounting rod 525.

[0042] The tube body is placed on the upper side of the support seat 12. At this time, the telescopic rod of the first hydraulic cylinder 524 is shortened and drives the rack 523 to move. At this time, the gear 522 engaged with the rack 523 drives the rotating shaft 521 to rotate under the drive of the rack 523 until it is spliced ​​into a ring with the support seat 12 in the vertical direction, thereby fixing the tube body; when driving the fixed plate 51 to open, the telescopic rod of the first hydraulic cylinder 524 is extended. At this time, the rack 523 drives the gear 522 to drive the fixed plate 51 to reverse through the rotating shaft 521 until the upper side of the support seat 12 is opened, so as to facilitate the placement of the tube body.

[0043] Reference Figure 1 and Figure 2 The lifting assembly 6 includes a movable box 61 located on the side of the support base 12 away from the mounting rod 525 and parallel to the length of the base plate 1. The two ends of the movable box 61 in the vertical direction are connected, and vertical rotating plates 62 are provided on both sides of the movable box 61 in the vertical direction. The lower sides of the rotating plates 62 are rotatably connected to the lower side of the movable box 61, and the two sides of one end of the movable box 61 are fixedly connected to the first motor 63 that drives the movable plate to rotate. A movable member 64 that drives the movable box 61 in the vertical direction is provided on the base plate 1.

[0044] The moving part 64 includes a vertical moving frame 641 fixedly connected to the side of the base plate 1 close to the moving box 61, and a vertical movable pulley 642 is rotatably connected to the middle part of the upper side of the moving box 61. The moving frame 641 is provided with a steel rope 643 with one end fixedly connected to the lower side of the moving frame 641, and a winch 644 is installed on the moving frame 641. The other end of the steel rope 643 passes through the lower side of the movable pulley 642 and is wound around the winch 644.

[0045] The first motor 63 drives the rotating plate 62 away from the support seat 12 to rotate, thereby driving the side of the moving box 61 away from the support seat 12 to open. At this time, the tube body is rolled into the moving box 61, and the rotating plate 62 is driven by the first motor 63 to rotate to close the moving box 61. The winch 644 reels the steel rope 643, thereby lifting the moving box 61 through the movable pulley 642 and driving the tube body to move to the upper side of the support seat 12. The first motor 63 drives the rotating plate 62 close to the support seat 12 to rotate. At this time, the rotating plate 62 close to the support seat 12 rotates to form a downward inclined surface, which facilitates the movement of the tube body into the support seat 12.

[0046] The implementation principle of a chamfering machine for spiral steel pipes in the embodiment of the present application is as follows: the pipe body is rolled into the moving box 61, and the rotating plate 62 is driven to rotate to close the moving box 61, and the winch 644 reels the steel rope 643, thereby lifting the moving box 61 and driving the pipe body to move to the upper side of the support seat 12, and the first motor 63 drives the rotating plate 62 close to the support seat 12 to rotate until the moving box 61 opens, and the pipe body moves to the support seat 12, and the fixed plate 51 fixes the pipe body, and the upper display just drives the chamfering box 2 to move and roughly adjusts the distance of the chamfering knife group 32, and the telescopic rod of the second hydraulic cylinder 33 drives the chamfering disk 31 and the chamfering knife group 32 to move to adapt to the chamfering length, and the second motor 353 drives the second bevel gear 352 to drive the first bevel gear 351 to rotate. At this time, the second hydraulic cylinder 33 fixed with the first bevel gear 351 drives the chamfering disk 31 and the chamfering knife group 32 to rotate, which is convenient for chamfering the end of the pipe body.
