[0039] See also Figure 1-6 The present invention provides a technical solution: an automatic positioning and cutting device for stainless steel pipes and a working method thereof, comprising a transmission part, an outer plate 1, a cutting part, a support wheel 3, a discharge block 4 and a feeding belt 8,

[0040] The outer plate 1 is provided with a pair, and the transmission part includes a driving transmission wheel 101 and a driven transmission wheel 102. The inner side of the driving transmission wheel 101 is rotatably connected with a central shaft 107. Both ends of the central shaft 107 are connected to the pair of outer plates 1. The wheel surfaces of the driving transmission wheel 101 and the driven transmission wheel 102 are set to a groove type adapted to the pipe material 6. The driving transmission wheel 101 and the driven transmission wheel 102 are respectively arranged at the upper and lower ends of the pipe material 6, and the pipe material 6 is clamped and transmitted;

[0041] One end of a pair of outer plates 1 is fixedly connected with a fixed plate 103, and the cutting part includes a cutting knife 2. A lifting mechanism is provided on one side of the cutting part. When the head end of the pipe material 6 contacts the fixed plate 103, the lifting mechanism drives the cutting knife 2 to descend to cut the pipe material 6. A limiting block 9 is fixedly connected between the pair of outer plates 1. An arc groove adapted to the pipe material 6 is provided on the upper side of the limiting block 9. The limiting block 9 and the cutting knife 2 are staggered.

[0042] An electric telescopic rod 401 is provided at the upper end of the unloading block 4, and the electric telescopic rod 401 drives the unloading block 4 to move downward, pushing the cut steel pipe body 7 onto the feeding belt 8;

[0043] There are several groups of support wheels 3 and they are arranged between the cutting part and the fixed plate 103. Several support wheels 3 are symmetrically arranged at both ends of the pipe material 6. The wheel surface of the support wheel 3 is arranged to be a groove type that matches the pipe material 6. The support wheel 3 supports the pipe material 6.

[0044] First, a transmission part is provided to transport the pipe material 6. Specifically, the active transmission wheel 101 and the driven transmission wheel 102 are distributed in upper and lower positions to clamp the pipe material 6 and transmit it to the fixed plate 103. The wheel surfaces of the active transmission wheel 101 and the driven transmission wheel 102 are provided with grooves, so as to further improve the friction with the pipe material 6 and ensure the stability of transmission. During transmission, the pipe material 6 passes through the upper side of the limit block 9, the lower side of the cutting part, the lower side of the discharge block 4 and between several support wheels 3 in sequence until the head end contacts the fixed plate 103, so as to determine the length of the steel pipe body 7 to be cut; then, the cutting knife 2 is driven to descend by the lifting mechanism, and the cutting knife 2 cooperates with the limit block 9 to cut the pipe material 6, so as to realize the control of the length of the steel pipe body 7 and automatic cutting. Preferably, the wheel surface of the support wheel 3 is similarly provided with a groove shape to increase the contact area with the pipe material 6. The pipe material 6 passes through several support wheels 3, and the support wheel 3 supports it to ensure the straightness of the pipe material 6 during cutting;

[0045] In order to further facilitate the smooth unloading of the cut steel pipe body 7, a unloading block 4 is provided. The unloading block 4 is driven to move by an electric telescopic rod 401 to push the cut steel pipe body 7 down to the feeding belt 8 to avoid the cut steel pipe body 7 getting stuck and unable to fall normally. The steel pipe body 7 can be sent to the next process after falling onto the feeding belt 8, thereby realizing the continuous automatic cutting function of the steel pipe body 7 without manual intervention, freeing up labor and improving work efficiency.

[0046] The inner side of the outer plate 1 is fixedly connected to the inner side plate 104, and the lifting mechanism includes a plurality of spring telescopic rods 105. The lower end of the spring telescopic rod 105 is connected to the upper end of the inner side plate 104, and the upper end of the spring telescopic rod 105 is provided with a lifting plate 106. A pair of lifting plates 106 are provided, and a pair of cutting support plates 201 are fixedly connected between the pair of lifting plates 106. The cutting knife 2 is arranged between the pair of cutting support plates 201. The inner side of the cutting knife 2 is fixedly connected to a rotating rod 202. Both ends of the rotating rod 202 pass through a pair of cutting support plates 201 and are rotatably connected thereto. A motor component 203 is fixedly connected to the side of the cutting support plate 201 away from the active transmission wheel 101, and the motor component 203 drives the rotating rod 202 to rotate.

[0047] Preferably, the motor 203 drives the rotating rod 202 to rotate, and the rotating rod 202 can drive the cutting knife 2 to rotate, and then the lifting plate 106 drives the cutting knife 2 to descend, so that the tube material 6 can be cut.

[0048] One end of the rotating rod 202 is fixedly connected to a worm 204, the upper end of the worm 204 is meshedly connected to a worm wheel 205, the interior of the worm wheel 205 is fixedly connected to a center rod 206, both ends of the center rod 206 are rotatably connected to the lifting plate 106, one side of the center rod 206 is fixedly connected to a pulley 1 207, one end of the pulley 1 207 is connected to a pulley 2 208, and one end of the pulley 208 is fixedly connected to the active transmission wheel 101.

[0049] Preferably, a worm wheel 205 and a worm 204 are provided. When the motor component 203 drives the cutting knife 2 to rotate, the rotating rod 202 also drives the worm 204 to rotate, thereby driving the worm wheel 205 to rotate. The worm wheel 205 drives the center rod 206 and the pulley 1 207 to rotate. The pulley 2 208 is driven to rotate by the transmission belt, which can drive the active transmission wheel 101 to rotate, thereby driving the pipe material 6 to be transmitted and loaded. In other words, the cutting knife 2 and the active transmission wheel 101 can be driven to rotate at the same time by the rotation of the motor component 203, so as to realize the functions of cutting and loading the pipe material 6. In addition, by utilizing the large transmission ratio of the worm gear mechanism, the rotation speed of the high-speed rotating cutting knife 2 is converted into the rotation speed of the slower active transmission wheel 101, which is more in line with the loading speed when the pipe material 6 is transported, and has strong practicality.

[0050] One side of the center rod 206 is rotatably connected to a connecting rod 209, one end of the connecting rod 209 is rotatably connected to the center axis 107, a pair of transverse grooves are opened on the inner side of the outer plate 1, both ends of the center axis 107 extend into the transverse grooves and slide with them, and the end of the transverse groove away from the cutting part is inclined upward.

[0051] Since the active transmission wheel 101 and the worm wheel 205 are linked by belt transmission, the linear distance between the two needs to be always guaranteed. Therefore, a connecting rod 209 is provided so that when the lifting plate 106 drives the cutting knife 2 to descend for cutting, the connecting rod 209 pushes the central shaft 107 and the active transmission wheel 101 to move and adapt, and the two ends of the central shaft 107 slide along the transverse groove until the cutting knife 2 contacts and cuts the tube material 6, thereby ensuring the normal transmission between the pulley 1 207 and the pulley 2 208 at all times;

[0052] Preferably, the transverse groove is set to be inclined, so that when the central axis 107 drives the active transmission wheel 101 to move along the transverse groove, it moves obliquely upward, so that the active transmission wheel 101 is separated from the contact with the tube material 6 and stops transmitting the tube material 6. That is to say, when the cutting knife 2 descends to contact the tube material 6 and cuts, the active transmission wheel 101 is separated from the tube material 6 at this time, which has a high degree of automation and strong practicality, improves the stability during cutting, and avoids the active transmission wheel 101 still transmitting the tube material 6 when the cutting knife 2 is cutting, causing the active transmission wheel 101 to rub against the tube material 6, resulting in poor surface quality.

[0053] The upper ends of a pair of lifting plates 106 are rotatably connected to a connecting shaft, and the middle side of the connecting shaft is fixedly connected to a rubber roller 110;

[0054] A spring telescopic rod 111 is provided on one side of the fixed plate 103, and a positioning block 112 is provided at one end of the spring telescopic rod 111. Both ends of the positioning block 112 are hingedly connected to a hinge block 113. A telescopic rod 114 is provided on the upper end of the hinge block 113. A hinge column 115 is connected to the upper end of the telescopic rod 114. Both ends of the hinge column 115 are rotatably connected to the outer plate 1. The upper end of the hinge column 115 is similarly provided with a telescopic rod 114. The upper end of the outer plate 1 is fixedly connected to a top plate 120. The top plate 120 is fixedly connected to the outer plate 120. 0 is provided with a pair of adapting grooves on the upper side, a pair of hinge blocks 116 are provided on the upper side of the top plate 120, the telescopic rod 114 passes through the adapting grooves and is connected to the hinge block 116, a guide groove is provided on the middle side of the top plate 120, a push rod 118 is slidably fitted in the guide groove, one end of the push rod 118 is fixedly connected to a hinge seat 117, both ends of the hinge seat 117 are hingedly connected to the hinge block 116, one end of the push rod 118 is fixedly connected to a friction plate 119, and the friction plate 119 corresponds to the rubber roller 110.

[0055] Preferably, in order to further improve the degree of automation in positioning and cutting the steel pipe body 7, a positioning block 112 is provided. Specifically, when the pipe material 6 is transmitted toward the fixed plate 103, its head end first contacts the positioning block 112 and pushes it, and the positioning block 112 is pushed to move toward the fixed plate 103, and the spring telescopic rod 111 is compressed. When the positioning block 112 moves, it drives the hinge block 113 connected by hinges at both ends to move, and the hinge block 113 drives the upper telescopic rod 114 and the hinge column 115 to rotate with the hinge column 115 as the axis, thereby driving the hinge seat 117 and the push rod 118 to move in the opposite direction, and the push rod 118 can push the friction plate 119 to move. When the friction plate 119 and the rubber roller 110 provided on the upper side of the lifting plate 106 When in contact (at this time, the positioning block 112 is in contact with the fixed plate 103), the rotating rubber roller 110 contacts the fixed friction plate 119 to generate friction, so that the rubber roller 110 is attached to the surface of the friction plate 119 and rolls downward, which can drive the lifting plate 106 and the cutting knife 2 to descend for cutting. After the cut steel pipe body 7 is unloaded, the positioning block 112 can return to its original position under the resetting action of the spring telescopic rod 111, so that the lifting plate 106 and the cutting knife 2 also rise and reset, and continue to start the next round of cutting operation. That is to say, the distance that the pipe material 6 pushes the positioning block 112 to move each time is certain, and the cutting knife 2 descends at the same time for cutting each time, with a high degree of automation, ensuring that the lengths of the cut steel pipe bodies 7 are equal.

[0056] One end of the center rod 206 is fixedly connected to a pulley three 108, one side of the pulley three 108 is connected to a pulley four 109, and the pulley four 109 is fixedly connected to the connecting shaft.

[0057] Preferably, a pulley three 108 and a pulley four 109 are provided so that when the center rod 206 rotates, the connecting shaft is synchronously driven to rotate, which can drive the rubber roller 110 to rotate. That is to say, a single motor component 203 not only drives the cutting knife 2 to rotate, but also synchronously drives the rubber roller 110 to rotate, thereby driving the cutting knife 2 to descend, thereby saving costs.

[0058] A wheel frame 301 is provided on one side of the support wheel 3, and a plurality of spring telescopic rods 302 are provided at one end of the wheel frame 301. One end of the spring telescopic rods 302 is connected to a support frame 303, and the support frame 303 is fixed to the outer end of the outer plate 1, and the wheel frame 301 and the support frame 303 are slidably matched.

[0059] Preferably, a plurality of spring telescopic rods 302 are provided so that a plurality of supporting wheels 3 are clamped on the outside of the pipe material 6 to support it, thereby ensuring the straightness of the pipe material 6 and the stability during cutting.

[0060] A triangular wedge block 304 is fixedly connected to the inner side of the wheel frame 301, a movable plate 402 is fixedly connected to the lower end of the electric telescopic rod 401, both ends of the movable plate 402 are slidably matched with the outer plate 1, a trapezoidal wedge block 403 is fixedly connected to the lower end of the movable plate 402, the trapezoidal wedge block 403 is adapted to the triangular wedge block 304, and a spring telescopic rod four 404 is arranged between the movable plate 402 and the unloading block 4.

[0061] Preferably, the electric telescopic rod 401 drives the moving plate 402 to move downward, thereby pushing the trapezoidal wedge blocks 403 at both ends to move, and the trapezoidal wedge blocks 403 are adapted to the inclined surfaces of the triangular wedge blocks 304, thereby pushing the triangular wedge blocks 304 to move, so that the wheel frame 301 and the supporting wheel 3 are away from the cut steel pipe body 7, and then the unloading block 4 unloads the steel pipe body 7;

[0062] In the initial state, the unloading block 4 is on the upper side of the pipe material 6 and is in clearance with it. When the movable plate 402 moves downward, since the support wheel 3 has not released the limit on the steel pipe body 7 at this time, the unloading block 4 cannot push the steel pipe body 7 to unload, but is attached to the upper side of the steel pipe body 7, and the spring telescopic rod four 404 is compressed until the support wheels 3 are separated from each other. Under the resetting action of the spring telescopic rod four 404, the unloading block 4 pushes the steel pipe body 7 to the upper side of the feeding belt 8. In other words, only by moving the movable plate 402, the driving of the support wheel 3 can be synchronously realized, the limit on the steel pipe body 7 can be released, and the unloading block 4 can also be driven to realize the unloading of the steel pipe body 7, which saves costs and has good synchronization between the two.
