Description

Technical Field

[0001] This application relates to the field of pipe cutting, and particularly to a cutting device for steel wire wound telescopic pipes. Background Art

[0002] The steel wire wound telescopic pipe includes a plastic telescopic pipe and wound steel wires integrated in the plastic telescopic pipe and arranged in a spiral manner. The structural strength of the steel wire wound telescopic pipe is ideal. Compared with traditional plastic telescopic pipes, the steel wire wound telescopic pipe is not easily deformed after bearing radial loads, that is, it is not easily flattened, which helps to ensure the medium flow in the inner cavity of the steel wire wound telescopic pipe. Therefore, the steel wire wound telescopic pipe is widely used in the drainage and exhaust fields.

[0003] During the production process of the steel wire wound telescopic pipe, continuous extrusion is carried out, and during the extrusion process, the steel wire wound telescopic pipe also rotates. Therefore, traditional cutting devices cannot be used to cut the steel wire wound telescopic pipe. In the prior art, manual cutting of the steel wire wound telescopic pipe into segments is usually adopted. First, the operator uses a cutter to pierce the steel wire wound telescopic pipe according to the length of the steel wire wound telescopic pipe. As the steel wire wound telescopic pipe rotates, the cutter cuts around the steel wire wound telescopic pipe in a circular manner. Then, the operator uses wire cutters to cut the connection part of the steel wire in the two sections of the steel wire wound telescopic pipe.

[0004] Since the manual cutting of the steel wire wound telescopic pipe during the production process has high requirements for the operator, at present, a cutting device for the steel wire wound telescopic pipe that can cut the steel wire wound telescopic pipe during the production process is needed. Summary of the Utility Model

[0005] This application provides a cutting device for steel wire wound telescopic pipes, which can cut the steel wire wound telescopic pipes during the production process.

[0006] The cutting device for steel wire wound telescopic pipes provided by this application adopts the following technical solutions:

[0007] A cutting device for steel wire wound telescopic pipes includes a main frame, a feeding cylinder installed on the main frame, and a discharging cylinder installed on the main frame. The discharging port of the feeding cylinder faces the feeding port of the discharging cylinder, and the discharging cylinder is arranged obliquely downward in the direction away from the feeding cylinder; there is a cutting gap between the feeding cylinder and the discharging cylinder; a cutter mechanism for cutting the steel wire wound telescopic pipe at the cutting gap and a punching mechanism for punching off the steel wire in the steel wire wound telescopic pipe at the cutting gap are also provided.

[0008] By adopting the above technical solution, since the discharge port of the feeding cylinder is directly opposite to the feeding port of the blanking cylinder, the steel wire wound telescopic tube can sequentially pass through the feeding cylinder, the cutting gap and the blanking cylinder. Since the steel wire wound telescopic tube discharges materials in a rotating manner during the production process, when the cutter mechanism cuts through the steel wire wound telescopic tube, the steel wire wound telescopic tube is still discharging materials in a rotating manner. Therefore, the cutter mechanism can perform a circumferential cut on the plastic part of the steel wire wound telescopic tube, so that after the circumferential cut by the cutter mechanism, only the steel wire connects the two sections of the steel wire wound telescopic tube. At this time, the punching mechanism can punch off the steel wire in this part, that is, the cutting operation of the steel wire wound telescopic tube is completed.

[0009] Among them, since the blanking cylinder is arranged obliquely, after the cutter mechanism circumferentially cuts the steel wire wound telescopic tube, the steel wire wound telescopic tube cracks at the circumferential cut, so that the steel wire connection area connecting the two sections of the steel wire wound telescopic tube is exposed, which helps the punching mechanism to punch off the steel wire in this part. The above-mentioned steel wire wound telescopic tube cutting equipment can cut the steel wire wound telescopic tube during the production process, so that the operator only needs to operate the steel wire wound telescopic tube cutting equipment, rather than manually cutting the steel wire wound telescopic tube by the operator.

[0010] Optionally, the cutter mechanism includes a cutter part and a driving part for driving the cutter part to move.

[0011] By adopting the above technical solution, the specific structure of the cutter mechanism is disclosed. The driving part can drive the cutter part to extend out, so as to be able to pierce the steel wire wound telescopic tube, and along with the self-rotation of the steel wire wound telescopic tube, complete the circumferential cutting operation of the steel wire wound telescopic tube. After the circumferential cutting is completed, the driving part can also drive the cutter part to reset to avoid interference of the cutter mechanism with the action of the punching mechanism.

[0012] Optionally, the punching mechanism includes a punching upper die that is installed on the main frame in a lifting and sliding manner, a punching lower die that is fixedly installed on the main frame, and a lifting component for driving the punching upper die to lift; the punching upper die has a punching convex part; the punching lower die has a punching groove for the punching convex part to penetrate into.

[0013] By adopting the above technical solution, the specific structure of a punching mechanism is disclosed. The punching upper die can punch off the steel wire connecting the two sections of the steel wire wound telescopic tube under the drive of the lifting component. During the punching operation, the steel wire wound telescopic tube is still rotating and conveying, so that the position of the steel wire connected to the steel wire wound tube also changes. Therefore, a punching convex part is provided, and the bottom surface projection of the punching convex part covers the above-mentioned area where the steel wire position changes, so that the above-mentioned punching mechanism can punch off the steel wire during the punching operation and generate a section of steel wire waste.

[0014] Optionally, the punching groove is a through groove structure.

[0015] By adopting the above technical solution, the punching groove is a through-groove structure, enabling the wire waste to be discharged from the punching groove after punching, so as to avoid interference of the wire waste with the next punching operation.

[0016] Optionally, the punching mechanism includes a punching module slidably mounted on the main frame and a driving component for driving the punching module to translate in a direction parallel to the axis of the feeding cylinder; the punching module includes a punching die holder, a shearing upper die slidably mounted on the punching die holder in a lifting manner, a shearing lower die fixed to the punching die holder and cooperating with the shearing upper die, and a lifting component for driving the shearing upper die to lift and lower.

[0017] By adopting the above technical solution, the specific structure of another punching mechanism is disclosed. During the punching operation, the wire-wound telescopic tube is still rotating and conveying. After being driven by the driving component, the above punching module can also move synchronously, so that the shearing upper die and the shearing lower die are always facing the wire area to be sheared. Then, the lifting component drives the shearing upper die to move downward to achieve the shearing of the wire. The above punching mechanism does not generate wire waste after punching.

[0018] Optionally, the driving component includes a rotating lead screw rotatably mounted on the main frame, a lead screw nut fixed to the punching module and cooperating with the rotating lead screw, and a driving motor for driving the rotating lead screw to rotate; the rotation axis of the rotating lead screw is parallel to the axis of the feeding cylinder.

[0019] By adopting the above technical solution, the specific structure of the driving component is disclosed. The driving component adopts a lead screw type linear driving module, which helps the punching module to keep the same feeding speed as the wire-wound telescopic tube.

[0020] Optionally, an infrared distance sensor is further provided. The discharging cylinder is provided with mounting through holes for installing the infrared distance sensor at intervals along the length direction, and the mounting through holes penetrate the inner and outer surfaces of the discharging cylinder.

[0021] By adopting the above technical solution, the infrared distance sensor is installed in the mounting through hole for detecting the depth of the wire-wound telescopic tube entering the discharging cylinder. When the end of the wire-wound telescopic tube extends into the detection area of the infrared distance sensor, the infrared distance sensor will generate a signal to the controller, and then the controller can control the actions of the cutting mechanism and the punching mechanism. Among them, multiple mounting through holes are provided on the discharging cylinder to adapt to wire-wound telescopic tubes with different length requirements, improving the adaptability of the wire-wound telescopic tube cutting equipment.

[0022] Optionally, a compressing device for compressing the steel wire wound telescopic tube output from the blanking cylinder is further provided; the compressing device includes a compressing bracket, a compressing base installed on the compressing bracket, and a compressing assembly for compressing the steel wire wound telescopic tube arranged in the compressing base; the compressing base has a compressing groove for receiving the steel wire wound telescopic tube output from the blanking cylinder; the compressing assembly includes a compressing head slidably arranged in the compressing groove and a driving cylinder for driving the compressing head to slide.

[0023] By adopting the above technical solution, the compressing device can compress the steel wire wound telescopic tube output from the discharge pipe, eliminating the need for manual compression by the operator, which helps to improve the automation level of the steel wire wound telescopic tube cutting equipment. When the cut steel wire wound telescopic tube is discharged from the blanking cylinder into the compressing groove of the compressing base, the compressing head will compress the steel wire wound telescopic tube under the drive of the driving cylinder.

[0024] Optionally, the compressing base is rotatably arranged on the compressing bracket, and the compressing bracket is further provided with a blanking motor for driving the compressing base to rotate, and the rotation axis of the compressing base is horizontally arranged.

[0025] By adopting the above technical solution, the blanking motor can drive the compressing base to rotate, so that the compressed steel wire wound telescopic tube can be dumped from the compressing base, facilitating the collection of the steel wire wound telescopic tube on the compressing base and the emptying of the compressing groove of the compressing base.

[0026] Optionally, the blanking cylinder is provided with a chamfer structure at the feed inlet.

[0027] By adopting the above technical solution, the steel wire wound telescopic tube output from the feed cylinder can be inserted into the feed inlet of the blanking cylinder more smoothly, reducing the probability that the steel wire wound telescopic tube output from the feed cylinder fails to enter the blanking cylinder, which helps to ensure the normal operation of the steel wire wound telescopic tube cutting equipment.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. A steel wire wound telescopic tube cutting device can cut the steel wire wound telescopic tube during the production process by setting a feed cylinder, a blanking cylinder, a cutting mechanism and a punching mechanism, enabling the operator to only operate the steel wire wound telescopic tube cutting device instead of manually cutting the steel wire wound telescopic tube by workers.

[0030] 2. By setting a compressing device, the cut steel wire wound telescopic tube can be compressed, eliminating the need for manual compression by the operator. Description of the Drawings

[0042] The following further elaborates on this application in conjunction with the attached Figure 1-10 drawings.

[0043] The embodiment of this application discloses a cutting device for wire-wound telescopic pipes, which is used to cut the wire-wound telescopic pipes during the production process.

[0044] Embodiment 1

[0045] Referring to Figure 1 , a cutting device for wire-wound telescopic pipes includes a main frame 1, a guiding assembly for guiding the wire-wound telescopic pipes, a cutter mechanism 2 installed on the main frame 1 and used for cutting the wire-wound telescopic pipes, a punching mechanism 3 installed on the main frame 1 and used for punching the wires in the wire-wound telescopic pipes, and a compression device 4 arranged on one side of the main frame 1.

[0046] Referring to Figure 2 , the main frame 1 includes an installation platform 11, four support legs 12 installed at the bottom of the installation platform 11, multiple guide columns 13 installed at the top of the installation platform 11, and a top platform 14 installed at the top of the multiple guide columns 13. Both the installation platform 11 and the top platform 14 are square platforms. The number of guide columns 13 is four and they are arranged in an array at the top of the installation platform 11.

[0047] Referring to Figure 2, the guiding component includes a feeding cylinder 15 and a blanking cylinder 16. Both the feeding cylinder 15 and the blanking cylinder 16 are installed on the main frame 1. On the main frame 1, there is a feeding support 151 for supporting the feeding cylinder 15 and a blanking support 161 for supporting the blanking cylinder 16. The axis of the feeding cylinder 15 and the axis of the blanking cylinder 16 are in the same vertical plane. Among them, the axis of the feeding cylinder 15 is horizontally arranged so that the wire-wound telescopic tube can enter the feeding cylinder 15 in the horizontal direction and be output in the direction of the blanking cylinder 16 horizontally. The blanking cylinder 16 is arranged obliquely downward in the direction away from the feeding cylinder 15. The feeding port of the blanking cylinder 16 is directly opposite to the discharging port of the feeding cylinder 15 so that the wire-wound telescopic tube output from the feeding cylinder 15 can enter the feeding cylinder 15.

[0048] Refer to Figure 2 and Figure 3 , a chamfer structure 162 is provided at the feeding port of the blanking cylinder 16 to reduce the probability that the wire-wound telescopic tube output from the feeding cylinder 15 fails to enter the blanking cylinder 16.

[0049] Refer to Figure 2 , there is a cutting gap 17 between the feeding cylinder 15 and the blanking cylinder 16, so that the wire-wound telescopic tube output from the feeding cylinder 15 needs to pass through the cutting gap 17 before it can enter the blanking cylinder 16.

[0050] Refer to Figure 2 and Figure 4 , the cutting mechanism 2 is installed on the main frame 1 and is used to cut the wire-wound telescopic tube at the cutting gap 17; the punching mechanism 3 is installed on the main frame 1 and is used to punch the wire in the wire-wound telescopic tube at the cutting gap 17.

[0051] Refer to Figure 2 and Figure 4 , the cutting mechanism 2 includes a cutting member 21 and a driving member for driving the cutting member 21 to move. The driving member is a first cylinder 22, and the cylinder body of the first cylinder 22 is fixedly installed on the main frame 1. The cutting member 21 is fixed to the end of the piston rod of the first cylinder 22 so that the telescopic movement of the piston rod of the first cylinder 22 can drive the cutting member 21 to move. In this embodiment, the cutting member 21 can obliquely pierce the lower edge part of the wire-wound telescopic tube. The end of the cutting member 21 is a tip so that the cutting member 21 can smoothly pierce the plastic part of the wire-wound telescopic tube, and the cutting edge part of the cutting member 21 is at the lower edge of the cutting member 21. During the rotation of the wire-wound telescopic tube, the plastic part of the wire-wound telescopic tube will rotate towards the cutting edge part, so that after the wire-wound telescopic tube is cut by the cutting member 21, the crack formed on the wire-wound telescopic tube is located on the upper side of the wire-wound telescopic tube, that is, the upper edge of the wire-wound telescopic tube cracks.

[0052] Refer to Figure 2 andFigure 4 The punching mechanism 3 includes a punching lower die 31, a punching upper die 32, and a lifting assembly for driving the lifting of the upper die. The punching lower die 31 is fixedly installed on the top surface of the installation platform 11 of the main frame 1 and is located at the cutting gap 17 between the feeding cylinder 15 and the discharging cylinder 16. A punching groove 311 is formed at the top of the punching lower die 31.

[0056] Refer to Figure 1 and Figure 6 As shown in FIGS.

[0057] Refer toFigure 1 and Figure 7 The compressing device 4 is arranged on one side of the main frame 1 where the blanking cylinder 16 is provided, and is used for compressing the wire-wound telescopic tube output from the blanking cylinder 16.

[0058] Referring to Figure 7 , a compressing groove 421 for receiving the wire-wound telescopic tube output from the blanking cylinder 16 is provided on the compressing base 42. The compressing groove 421 is a V-shaped groove, so that when the wire-wound telescopic tube falls into the compressing groove 421, it can be supported by the two inclined sides of the compressing groove 421. Among them, the compressing base 42 has side plates at both ends of the compressing groove 421, which are respectively a first side plate 422 close to the blanking cylinder 16 and an installation side plate 423 far from the blanking cylinder 16.

[0059] Referring to Figure 1 and Figure 7 , the compressing assembly 43 includes a compressing head 431 slidably arranged in the compressing groove 421 and a driving cylinder 432 for driving the compressing head 431 to slide along the direction of the compressing groove 421. The compressing head 431 is in the shape of a disc with a horizontal axis, and the compressing head 431 is arranged tangentially to the two inclined surfaces of the compressing groove 421.

When the wire-wound telescopic tube is output from the blanking cylinder 16 and arranged in the compressing groove 421, the compressing head 431 can compress the wire-wound telescopic tube after being driven by the driving cylinder 432.

[0060] Referring to Figure 1 and Figure 7 , rotating convex columns 424 are provided at both ends of the compressing base 42, and rotating holes 411 for rotatably supporting the rotating convex columns 424 are provided on the compressing bracket 41, so that the compressing base 42 can be rotatably arranged on the compressing bracket 41. Among them, the rotation axis of the compressing base 42 is horizontally arranged. The blanking motor 44 is installed on the compressing bracket 41, and the output shaft of the blanking motor 44 is connected to one of the rotating convex columns 424 of the compressing base 42. When the wire-wound telescopic tube is compressed, the blanking motor 44 drives the compressing base 42 to rotate, so that the compressed wire-wound telescopic tube can be poured out of the compressing base 42, thereby completing the blanking of the wire-wound tube.

[0061] Combined with Figures 1 to 7, the working principle of the steel wire wound telescopic pipe cutting equipment in this embodiment is as follows:

[0062] 1. The steel wire wound telescopic pipes that have been produced pass through the feeding cylinder 15 and the cutting gap 17 in sequence and enter the discharging cylinder 16;

[0063] 2. After the infrared distance sensor 163 on the discharging cylinder 16 detects the steel wire wound telescopic pipe, that is, when the steel wire wound telescopic pipe reaches the cutting length, the infrared distance sensor 163 sends a signal to the controller, and the controller controls the cutting tool mechanism 2 and the punching mechanism 3 to act;

[0064] 3. The cutting tool member 21 in the cutting tool mechanism 2 extends out and pierces the plastic part of the steel wire wound telescopic pipe. As the steel wire wound telescopic pipe rotates self - rotatably, a crack is formed in the upper part of the steel wire wound telescopic pipe, and the steel wire part connecting the two sections of the steel wire wound telescopic pipe is aligned with the punching protrusion 322 of the punching mechanism 3;

[0065] 4. The punching mechanism 3 acts. The punching cylinder drives the punching upper die 32 to move downward. The punching protrusion 322 cooperates with the punching groove 311 to punch off the above - mentioned steel wire part, completing the cutting of the steel wire wound telescopic pipe;

[0066] 5. The cut steel wire wound telescopic pipe falls from the discharging cylinder 16 into the compression groove 421 of the compression device 4;
