Description

Technical Field

[0001] This utility model relates to the field of fiberglass composite pipe production technology, specifically a cutting device for fiberglass composite pipe production. Background Technology

[0002] Cutting equipment used in the production of fiberglass composite pipes is a key piece of equipment used to precisely divide ultra-long pipes into specified lengths after continuous forming. Due to the high hardness and complex structure of fiberglass composite pipes, chipping, delamination, or internal damage are very likely to occur during the cutting process. Therefore, a specially designed cutting device is necessary to efficiently and with low loss complete clean and neat cross-section cutting, ensuring the performance and dimensional accuracy of the final pipe section.

[0003] However, traditional fiberglass tube cutting devices lack a composite positioning mechanism that effectively constrains the circumferential rotation and axial movement of the tube. This can easily lead to rough cuts and burrs due to tube misalignment, making it difficult to meet high-precision cutting requirements. Furthermore, existing cutting feed mechanisms mostly rely on simple slides, lacking the coordinated control of rigid guidance and precision thread drive. This can easily cause the cutting trajectory to deviate, resulting in skewed cuts or out-of-tolerance dimensions. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 As shown, this utility model provides a technical solution:

[0025] A cutting device for producing fiberglass composite pipes includes a guide frame 101 and a bracket 102. Slide rails 103 are fixedly installed on both sides of the top of the guide frame 101. Sliding clamps 104 are slidably installed on the outer sides of the slide rails 103. An internally threaded block 105 is fixedly installed between the sliding clamps 104. The internally threaded block 105 is slidably disposed inside the guide frame 101. A threaded rod 106 is threadedly installed in the middle of the internally threaded block 105. Both ends of the threaded rod 106 are mounted inside the guide frame 101 via bearings. One end of the threaded rod 106 extends to the outer side of the guide frame 101 and connects to the output end of a drive motor 107. The drive motor 107 is bolted to the outer side of the guide frame 101. Fixing plates 108 are fixedly installed on both sides of the bottom of the guide frame 101, and fixing holes 109 are provided on the fixing plates 108.

[0026] The above scheme achieves the following: the guide frame serves as the basic framework for supporting the slide rail and the threaded drive mechanism; the bracket provides stability for the overall device; the slide rail guides the sliding clamp to move linearly; the sliding clamp connects the internal threaded block and the slide rail for sliding transmission; the internal threaded block converts the rotational motion of the threaded rod into linear motion; the threaded rod transmits the torque of the drive motor; the drive motor provides the power source for the lateral feed of the cutting device; the fixing plate serves as the mounting base for connecting external equipment; and the fixing holes provide positioning and fixing for bolt fastening.

[0027] In this embodiment, preferably, an assembly plate 110 is bolted to the top of the internal thread block 105, a support plate 111 is fixedly installed on one side of the top of the assembly plate 110, and a diagonal brace 112 is fixedly installed at the connection between the support plate 111 and the assembly plate 110.

[0028] The above scheme achieves modular connection between the cutting unit and the moving mechanism through the assembly plate, provides a vertical mounting platform to support the cutting motor through the support plate, and strengthens the support plate by increasing its bending stiffness through the diagonal bracing plate.

[0029] In this embodiment, preferably, a cutting motor 113 is bolted to one side of the support plate 111 and located on the same plane as the diagonal brace 112. The output end of the cutting motor 113 passes through the support plate 111 via a shaft and is fitted with a cutting blade 114 using fasteners.

[0030] The above scheme uses a cutting motor to drive the cutting blade to rotate at high speed, thereby achieving the cutting action on the fiberglass composite pipe.

[0031] In this embodiment, preferably, a support platform 115 is fixedly installed at the top of the bracket 102, and a connecting plate 116 is bolted to the top of the support platform 115. The connecting plate 116 is fixedly installed on both sides of the bottom end of the conveying frame 117.

[0032] The above scheme achieves the supporting function of lifting the conveying mechanism to the working height through the support platform, the rigid connection function of the conveying frame and the support platform through the connecting plate, and the frame structure function of accommodating the pipe conveying components through the conveying frame.

[0033] In this embodiment, preferably, the top of the conveying frame 117 is threaded with a plurality of adjusting screws 118, the ends of the adjusting screws 118 extending into the sliding grooves 119 and connecting to the pressure plate 120, and the sliding grooves 119 are respectively opened on both sides of the conveying frame 117.

[0034] The above scheme achieves precise control of manually adjusting the height of the pressure plate by adjusting the screw, guides the vertical movement trajectory of the pressure plate by adjusting the sliding groove, and transmits pressure to the clamping mechanism by adjusting the pressure plate.

[0035] In this embodiment, preferably, springs 121 are fixedly installed at the bottom of the pressure plate 120 located in the sliding groove 119, and limit blocks 122 are fixedly installed at the bottom of the springs 121, with support shafts 123 installed between the limit blocks 122 via bearings.

[0036] The above scheme achieves the elastic adjustment of buffering pipe vibration and dynamically compensating for clamping force through spring, the positioning function of constraining the axial position of the support shaft through limit block, and the rotation carrier function of installing the first inner inclined roller through support shaft.

[0037] In this embodiment, preferably, a first inner inclined roller 124 is fixedly installed on the support shaft 123 inside the conveying frame 117, and a second inner inclined roller 125 is respectively provided directly below the first inner inclined roller 124. The conveying channel formed between the first inner inclined roller 124 and the second inner inclined roller 125 is perpendicular to the moving path of the cutting blade 114.

[0038] The above scheme achieves the adaptive clamping and centering of the pipe by forming a V-shaped channel through the first and second inner inclined rollers, and achieves the self-locking stabilizing effect by generating bidirectional force through the contact of the inclined surfaces of the two rollers to prevent the pipe from moving axially. The precise cutting effect with no burrs on the cross-section is achieved by the coordinated movement of the vertical cutting path and the rotating pipe.

[0039] In this embodiment, preferably, a rotating shaft 126 is fixedly installed in the middle of the second inner inclined roller 125. One of the rotating shafts 126 passes through the conveying frame 117 and is connected to the output end of the rotating motor 127. The rotating motor 127 is installed on the side directly below the sliding groove 119 by bolts.

[0040] The above scheme achieves the power transmission function of transmitting torque to the second inner inclined roller through the rotating shaft, and provides the active conveying function of driving the pipe to rotate at a uniform speed through the rotating motor.

[0041] In this embodiment, a cutting device for producing fiberglass composite pipes is used by first horizontally placing the fiberglass composite pipe to be cut into the conveying frame 117. The pressure plate 120 is driven to move downwards within the sliding groove 119 by turning the adjusting screw 118. The elastic compression of the spring 121 causes the limiting block 122 to drive the support shaft 123 to descend synchronously, thereby bringing the first inner inclined roller 124 into contact with the top of the pipe. This adaptive clamping mechanism can adapt to the processing requirements of different pipe diameters. After setting the basic pressure by adjusting the screw 118, the spring 121 can dynamically compensate for gaps caused by pipe tolerances or vibrations, ensuring that the pipe is stably clamped in the V-shaped conveying channel formed by the first inner inclined roller 124 and the second inner inclined roller 125, avoiding displacement deviation during cutting. When the device is started... When the rotating motor 127 is activated, the rotating shaft 126 drives the second inner inclined roller 125 to rotate synchronously. The friction between the roller surface and the pipe drives the pipe to rotate at a constant speed around its own axis. At this time, the cutting motor 113 is started, driving the cutting blade 114 to rotate at high speed. At the same time, the drive motor 107 is started, driving the threaded rod 106 to rotate. Through the thread engagement with the inner threaded block 105, the inner threaded block 105 is smoothly translated along the slide rail 103 in the guide frame 101. This precision drive structure can eliminate lateral offset: the sliding clamp 104 is limited to horizontal movement by the slide rail 103, and the sliding engagement between the inner threaded block 105 and the guide frame 101 further constrains the movement trajectory, thereby ensuring that the movement trajectory of the cutting unit installed on the assembly plate 110 is always a straight line. As the threaded rod 106 continues to rotate, the entire cutting unit (including the support plate 111, the inclined support plate 112, the cutting motor 113, and the blade) feeds horizontally in sync. The high-speed rotating cutting blade 114 cuts vertically into the uniformly rotating pipe. During the cutting process, the circumferential motion of the pipe makes the circumferential cutting load of the blade evenly distributed, while the linear feed of the cutting unit ensures that the cut is flat. After the blade completes the radial cutting of the pipe, the drive motor 107 reverses and drives the cutting unit to reset. This collaborative working method realizes the combined motion of axial translational cutting and circumferential rotation of the pipe, which solves the technical defects of traditional cutting of fiberglass pipes that are prone to burrs and chipping. In particular, the V-shaped channel formed by the bidirectional inner inclined rollers can accurately center and position the pipe while transmitting it efficiently. Combined with the dual pressure control system of the adjusting screw 118 and the spring 121, it ensures that pipes of various specifications can obtain a smooth and flat cutting surface.
