In the embodiment, a rotary cylinder is adopted to construct the swing actuator 70, a multi-rod cylinder is adopted to construct the telescopic actuator 71, a finger cylinder is adopted to construct the main body structure of the pipe clamp 73, and the cylinders are adopted to construct the swing actuator and the telescopic actuator, so that the existing air pressure station on the spinning machine can be fully utilized to provide a power source, and the structure and equipment cost of the swing material moving system are effectively simplified; specifically, a telescopic actuator is constructed using parallel-bar cylinders. Of course, for the telescopic actuator 71, a multi-rod cylinder, or a cylinder, a cylinder and a guide mechanism, or a linear motor may be used. The swing actuator 70 may be constructed by using a rack and pinion mechanism in cooperation with an air cylinder, an oil cylinder, or a servo motor. The pipe clamp 73 may be constructed by using a clamp die that is pushed by two or more cylinders, or the like. In order to facilitate the adjustment of the position of the pipe clamp 73 in the X-axis direction during the installation of the device, so as to improve the installation accuracy and reduce the manufacturing difficulty, the pipe clamp 73 is installed on the telescopic end of the telescopic actuator 71 through the traverse fine adjustment mechanism 74; specifically, the traverse fine adjustment mechanism 74 includes a support rail 740 fixed to the telescopic end of the telescopic actuator 71, a slider 741 suspended and supported on the support rail 740 so as to be slidable along the support rail 740, and a quick release mechanism 742 for locking the relative position between the slider 741 and the support rail 740, wherein the support rail 740 and the slider 741 are suspended, supported and engaged in a dovetail groove structure, and the cylinder body of the finger cylinder is fixed to the slider 741. Wherein the swing actuator 70, together with the telescopic actuator 71, and the traverse fine adjustment mechanism 74 for fine adjustment of the lateral position of the tube clamp, constitute the connection mechanism 72 in this embodiment for mounting the tube clamp 73 on the swing end of the swing arm 51, i.e., in this embodiment, the tube clamp unit 7 includes the tube clamp 73 and the connection mechanism 72 for mounting the tube clamp 73 on the swing end of the swing arm 51.

In order to clamp the tube 03 by the clamping rollers, at least three clamping rollers are required to clamp and support the tube 03 from three directions, and the three supporting points cannot be located on the same semi-circumferential surface, that is, the connecting lines of the clamping supporting points of at least three clamping rollers to the tube form an acute triangle. The finger cylinder 730 constitutes an opening and closing actuator for opening and closing the both-side jaws. Of course, in order to reduce the deflection stress caused by the rotary cutting of the pipe 03 during the clamping process, the clamping roller is set to be an elastic wheel, or the supporting arm is movably connected with the side clamping jaw, an inner sleeve and an outer sleeve are specifically adopted, and the supporting arm is sleeved with a compression spring which enables the supporting arm to be far away from the side clamping jaw, so that the clamping roller is elastically and floatingly installed on the side clamping jaw.

The stator 610 of the linear displacement output device 61 is located on the side of the spinning wheel 320 of the second spinning machine 12 away from the second clamping jaw 311, and specifically, the stator 610 is fixed on the mounting base plate 38 shown in fig. 6 through a bracket. In the working process, the multi-rod cylinder drives the piston rod to move along the negative direction of the X axis, so that the material pushing plate 60 is pushed to a pipe end processing avoiding area, and interference to pipe end processing processes such as spinning and the like is avoided. Wherein the ejector plate 60 constitutes the ejector head in this embodiment.

In this embodiment, taking the production and manufacture of the silencer 03 shown in fig. 17 as an example, the working process of the spinning system is exemplarily described, and specifically includes the following steps:

the first spinning step S1 is to control the first spinning machine 11 to spin out the necking end 010 at the front end of the long tube 01 to obtain the semi-finished tube 02 connected to the long tube, control the swing material moving system to clamp the semi-finished tube 02 from the first clamping claw, cut the semi-finished tube 02 from the long tube by the cutting device, and raise the semi-finished tube to a tube end processing avoiding area higher than the first clamping claw 211.

In the first spinning step S1, the swing arm 51 swings until the pipe clamp unit 7 is located at a position directly above the first clamping claw 211, that is, the swing end of the swing arm 51 is located at the first position in the present embodiment, and the telescopic actuator 71 is brought into the retracted state, while the pipe clamp 73 is located at a region directly above the first clamping claw 211, to avoid the pipe end processing process such as spinning, inner hole turning, or the like, even if the pipe clamp 73 is located at the first pipe end processing avoiding region.

Specifically, the first spinning step S1 includes:

in the tube end positioning step S11, the feeding and traveling mechanism 25 is controlled to drive the spinning wheel 220 to move to a positioning position right in front of the first clamping claw 211, and then the tail feeding device 10 is controlled to feed the long tube material 01 until the front end surface of the long tube material 01 abuts against the end surface of the spinning wheel 220, so as to position the tube end.

In the spinning forming step S12, the rotating spindle 210 is driven to rotate the long tubular member 01 through the first clamping claw 211, and the control feeding traveling mechanism 25 drives the spinning wheel 220 to move according to a predetermined track, so as to spin a formed tubular portion 010 with a predetermined shape on the front end portion of the long tubular member 01, where the specific structure of the formed tubular portion 010 is as shown in fig. 17.

A port trimming step S13, wherein the spinning wheel 220 is controlled to exit the spinning position; then, the rotary driving device is controlled to drive the rotary main shaft 210 to drive the long pipe material 01 to rotate through the first clamping claw 211, the feed travelling mechanism 25 is controlled to drive the cutting tool 26 to feed to the end side of the forming end portion 010 so as to perform end face flattening processing on the necking portion of the forming end portion 010, and the inner hole turning tool 28 is driven to extend into the forming end portion 010 so as to perform inner hole turning finishing processing and end face chamfering processing on the necking portion of the forming end portion 010.

And a pipe end secondary positioning step S14, in which the feeding and traveling mechanism 25 is controlled to drive the spinning wheel 220 to move to a positioning position right in front of the first clamping claw 211, and then the tail feeding device 10 is controlled to push the long pipe 01 until the front end surface of the long pipe 01 abuts against the end surface of the spinning wheel 220, so as to perform secondary positioning on the pipe end, and cut out a semi-finished pipe 02 with a fixed length. In the first spinning step S1, the tube end surface is positioned twice so that the length of the tube outside the first clamping claw during spinning is short to improve the structural strength and ensure the machining accuracy, and the second positioning is performed with the tube end surface after cutting as a reference to further improve the machining accuracy.

In the cutting step S15, the telescopic actuator 71 is controlled to extend so that the pipe gripper 73 moves down to be gripped on the front end portion of the long pipe material 01, the four gripping rollers are controlled to grip the outer peripheral surface of the long pipe material 01, and the pipe section is cut off from the long pipe material 01 by a cutting device in a predetermined length to obtain a semi-finished pipe material 02.

And a step S16 of raising, controlling the telescopic actuator 71 to retract, so that the pipe clamping jaw 73 carries the semi-finished pipe material 02 to move up to the first pipe end processing avoiding area. So that the first spinning machine 11 can continue the spinning process of the next semifinished product.

In the swing material moving step S2, controlling a swing driving device to drive a swing arm 51 to swing to a second pipe end processing avoiding area where the semi-finished pipe material 02 is located above the second material clamping claw 311; then, controlling the swing material moving system to adjust the position of the semi-finished tube material until the semi-finished tube material is positioned right in front of the second material clamping claw 311; and then controlling the material pushing device 6 to push the part of the semi-finished tube 02 with the necking end facing the second clamping claw 311 into the second clamping claw 311 so as to be clamped by the second clamping claw 311.

Specifically, the swing material moving step S2 includes the following steps:

in the swing step S21, the swing driving device is controlled to drive the swing arm 51 to swing from the first position to a position where the swing end is located directly above the second clamping claw 311, i.e. at the second position in the present embodiment, and at this time, the tube is located at the stop position in the present embodiment, and the pushing device pushes the tube toward the spinning station of the second spinning machine 12 along the axial direction of the tube. In this embodiment, the swing is 180 degrees from the first position to the second position. Since the rotary shaft 510 is arranged substantially in the horizontal direction, that is, in the present embodiment, the axial direction of the rotary shaft 510 is arranged in parallel to the axial direction of the tube material held on the tube clamp 73, during the swing, the swing arm 51 swings at the upper side region of the rotary shaft 510 to reduce the layout interference with the two spinning machines.

In the direction adjustment step S22, the swing actuator 70 is controlled to adjust the extending direction of the telescopic actuator 71 to point to the second gripper jaw 311, i.e. the second gripper jaw constitutes the current gripper jaw at this time.

Specifically, the swing actuator 70 is controlled to rotate the telescopic actuator 71 and the tube clamp 73 by 180 degrees about an axis parallel to the Y-axis direction, that is, from the state shown in fig. 11 to the state shown in fig. 12 and 14, at which time the driving direction of the mover of the telescopic actuator 71 is arranged along the Z-axis direction. That is, in the present embodiment, the telescopic actuator 71 is used to drive the pipe clamp 73 to move in the vertical direction to adjust the pipe clamp 73 to the pipe end treatment avoiding region, and to extend from the pipe end treatment avoiding region to the loading position or the unloading position to drive the pipe clamp 73 to extend to move from the pipe end treatment avoiding region to the clamping claw, and to retract to move from the clamping claw to the pipe end treatment avoiding region, that is, the telescopic actuator 71 constitutes the avoiding actuator in the present embodiment. Of course, other mechanisms may be used to construct the avoidance actuator, and the avoidance actuator is necessarily a telescopic actuator, and only needs to be configured to drive the pipe clamp 73 to move in the avoidance channel between the pipe end processing avoidance area and the material clamping claw, specifically, the avoidance actuator may be configured to drive the pipe clamp 73 to move from the first pipe end processing avoidance area to the first material clamping claw 211 to clamp the pipe material on the first material clamping claw 211 and then move away from the first pipe end processing avoidance area at least when the swing arm 51 swings to the first position, and drive the pipe clamp 73 to move close to the second material clamping claw 311 to transfer the clamped pipe material to the position between the second material clamping claw 311 and the material pushing device 6 and then move away from the second pipe end processing avoidance area when the swing arm 51 swings to the second position. That is, in the present embodiment, the connecting mechanism 72 is used not only to adjust the positional distance between the pipe clamp 73 and the swing end of the swing arm 51, but also to adjust the posture of the pipe clamp 73 with respect to the swing end, that is, to adjust the posture of the pipe clamp 73 with respect to the swing end.

In the feeding step S23, the linear displacement output device 61 of the material pushing device 6 is controlled to drive the material pushing plate 60 to move forward along the X axis, so as to push the tube 02 clamped on the tube clamp 73 into the second clamping claw 311, and the tube 02 is clamped by the second clamping claw 311, i.e. the tube 02 is pushed along the tube spindle of the tube clamp 73. Before pushing the material, the clamping force on the pipe material can be properly reduced.

The second spinning step S3 controls the second spinning machine 12 to spin a throat end portion 011 on the other end of the semifinished tube material 02 to obtain the muffler 03.

And a discharging step S4, controlling the traverse driving mechanism 146 to drive the feed inlet of the receiving hopper 145 to extend to a position right below the second clamping claw 311, pushing the silencer 03 out of the second clamping claw 311 by using a discharging mechanism in the second spinning machine 12, sequentially passing through the receiving hopper 145 and the intermediate sliding hopper 144, and finally rolling into the finished product hopper 142.

The specific structure and discharging manner of the discharging device are not limited to the discharging structure and discharging manner in the embodiment, and the discharging device can also adopt a corresponding device in the existing product to discharge.

The above steps are repeated to continuously process the finished pipe material, i.e. the silencer 03.

When the swing end of the swing arm 51 swings back to the position right above the second gripper claw 211 from the position right above the second gripper claw 311, the swing actuator 70 also needs to be controlled to drive the telescopic actuator 71 to perform position adjustment, that is, in this embodiment, the swing actuator 70 is controlled to adjust the extending direction of the telescopic actuator 71 to point to the current gripper claw when the swing end of the swing arm 51 is located at the first position and the second position; specifically, the tube end processing avoiding region is located directly above the current gripping claw so that the telescopic actuator 71 drives the tube clamp 73 vertically closer to or farther from the current gripping claw, thereby reducing interference.

Of course, the adjustment of the telescopic direction of the telescopic actuator 71 by the swing actuator 70 is not limited to the adjustment at the first position and the second position in the present embodiment, and the swing can be suspended in the swing process and at a certain position in the process for adjustment, that is, the swing actuator 70 adjusts the pose of the telescopic actuator 71, so that the pipe clamp 73 moves from the current pipe end processing avoiding region to the current clamping claw, and the extending direction of the telescopic actuator 71 all points to the current clamping claw.

Further, the mounting base 50 may be mounted on the traverse driving mechanism to adjust the position of the tube clamp 73 in the Y-axis direction.
