Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a cutting equipment for steel core reinforced FRP pultruded profiles. Background Technology

[0002] FRP profiles have many advantages such as being lightweight, high-strength, and corrosion-resistant, making them suitable for manufacturing cables or prestressing tendons to replace traditional steel cables or steel prestressing tendons. This improves the mechanical properties and durability of civil engineering structures. The strength of the profile is enhanced by adding a steel core inside, and the profiles need to be cut using cutting equipment during processing.

[0003] The cutting saw blades and cutting speed parameters used for cutting FRP profiles and steel are different. If an FRP profile saw blade is used, the cutting speed is slow and the saw blade wear is large when cutting the steel core. However, if a steel cutting saw blade is used, it will cause the FRP part to burn and turn black. Utility Model Content

[0004] To address the issue that the existing cutting saw blades and cutting speed parameters used for cutting FRP profiles and steel are different, if an FRP profile saw blade is used, the cutting speed is slow and the saw blade wear is high when cutting the steel core. However, if a steel cutting saw blade is used, it will cause the FRP parts to burn and turn black.

[0005] This utility model provides a cutting device for steel-core reinforced FRP pultruded profiles, which adopts the following technical solution:

[0006] A cutting device for steel-core reinforced FRP pultruded profiles includes a frame, a profile conveying component is provided on the inner bottom wall of the frame, an electric push rod is fixedly inserted into the inner top wall of the frame, an adjustable double-headed cutting component is fixedly provided at the extended end of the electric push rod, a blocking frame is fixedly provided on the inner bottom wall of the frame, and a detection probe is provided at the bottom of the adjustable double-headed cutting component.

[0007] The above technical solution involves first conveying the profile to the adjustable double-headed cutter via a profile conveyor, then using an electric push rod to move the adjustable double-headed cutter downwards to cut the profile. One of the blades of the adjustable double-headed cutter cuts the FRP on the outside of the profile, while a blocking frame blocks the adjustable double-headed cutter to reduce the possibility of it directly cutting the steel core. The other blade of the adjustable double-headed cutter then cuts the steel core.

[0008] Optionally, in the above-mentioned steel-core reinforced FRP pultruded profile cutting equipment, the inner bottom wall of the frame is provided with a groove, and the profile conveying component is arranged in the groove.

[0009] The above technical solution facilitates the transport of profile conveyor components via a chute.

[0010] Optionally, in the above-mentioned steel-core reinforced FRP pultruded profile cutting equipment, the profile conveying component includes two side plates, the two side plates are connected by a first double-headed push rod, an arc-shaped clamp is fixedly provided on the opposite side of each of the two side plates, a first motor is fixedly provided on the side wall of the arc-shaped clamp, a turntable is fixedly sleeved on the rotating shaft of the first motor, and two profile conveying cylinders are hinged to the opposite side of the two side plates.

[0011] The above technical solution allows the first double-headed push rod to easily pull the two side plates to retract, thereby clamping the profile through two arc-shaped blocks. Then, the first motor drives the turntable to rotate, which in turn drives the profile to rotate synchronously. At the same time, the adjustable double-headed cutting component cuts the profile.

[0012] Optionally, in the above-mentioned steel-core reinforced FRP pultruded profile cutting equipment, a limiting block is fixedly provided at the bottom of the side plate, and the limiting block is located in the slid groove and slides in cooperation with the inner wall of the slid groove.

[0013] The above technical solution allows for the sizing of the side plate by using a limiting block in conjunction with a sliding groove, thereby increasing the stability of the side plate during movement.

[0014] Optionally, in the above-mentioned steel-core reinforced FRP pultruded profile cutting equipment, both ends of the profile conveying cylinder are hinged with hinge rods, and the end of the hinge rod away from the profile conveying cylinder is hinged to the side wall of the side plate.

[0015] With the above technical solution, when the two side plates expand, the hinge rod unfolds and pulls the two profile conveying cylinders to contract, thereby clamping the profiles through the profile conveying cylinders to facilitate the conveying of the profiles.

[0016] Optionally, in the above-mentioned steel-core reinforced FRP pultruded profile cutting equipment, the profile conveying cylinder includes two circular plates and a rubber column. The rubber column is rotatably disposed between the two circular plates. An annular groove is formed on the outer wall of the rubber column. A second motor is fixedly disposed on the side wall of the circular plate. The second motor is fixedly connected to one end of the rubber column.

[0017] The above technical solution allows the second motor to easily drive the rubber column to rotate, which in turn facilitates the conveying of the profile.

[0018] Optionally, in the above-mentioned steel-core reinforced FRP pultruded profile cutting equipment, the adjustable double-head cutting component includes a second double-head push rod and two fixed frames. The second double-head push rod is fixedly installed at the extended end of the electric push rod, and the two fixed frames are respectively fixedly installed at both ends of the second double-head push rod. A telescopic rod is provided between the two fixed frames. Each of the two fixed frames is equipped with a cutting head, and the two cutting heads are of different sizes. The detection probe is installed at the bottom of the fixed frame above the blocking frame.

[0019] The above technical solution allows for easy adjustment of the distance between the two fixed frames and the two cutting heads via the second double-headed push rod, and increases the stability of the two fixed frames during movement via the telescopic rod. One of the two cutting heads is an FRP profile saw blade, and the other is a steel cutting saw blade, thereby enabling the separate cutting of the steel core and FRP material of the profile.

[0020] Optionally, in the above-mentioned steel-core reinforced FRP pultruded profile cutting equipment, the blocking frame includes an arc-shaped support plate and two non-metallic mandrels. The arc-shaped support plate is fixedly installed on the inner bottom wall of the frame, and the two non-metallic mandrels are symmetrically arranged on the top of the arc-shaped support plate. A discharge port is opened in the arc-shaped support plate, and the material of the non-metallic mandrels is wood, plastic or glass fiber.

[0021] The above technical solution reduces the possibility of the FRP profile saw blade cutting the steel core by using two non-metallic core rods in conjunction with the detection probe, and facilitates the support of the profile by using an arc-shaped support plate, and facilitates the discharge of cutting debris by using a discharge port.

[0022] In summary, this utility model has at least one of the following beneficial effects:

[0023] The adjustable double-headed cutter is blocked by a blocking bracket to reduce the possibility of it directly cutting the steel core. The two blades of the adjustable double-headed cutter cut the steel core and FRP separately, thereby reducing the increase of blade wear and the possibility of burning and blackening of the FRP part on the profile.

[0024] The first motor drives the turntable to rotate, controlling the rotation of the profile. When the two side plates expand, the hinge rod unfolds and pulls the two profile conveying cylinders to retract, thereby clamping the profile through the profile conveying cylinders to facilitate the conveying of the profile. Therefore, the rotation and conveying of the profile are more convenient. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a steel core reinforced FRP pultruded profile cutting device, which includes a frame 1, a profile conveying component 2 provided on the inner bottom wall of the frame 1, a groove 11 provided on the inner bottom wall of the frame 1, and the profile conveying component 2 is disposed in the groove 11, so that the profile conveying component 2 can be easily conveyed through the groove 11.

[0031] An electric push rod 3 is fixedly inserted into the inner top wall of the frame 1. An adjustable double-headed cutting component 4 is fixedly installed at the extended end of the electric push rod 3. The profile conveying component 2 includes two side plates 21. The two side plates 21 are connected by a first double-headed push rod 22. An arc-shaped clamping block 23 is fixedly installed on the opposite side of each of the two side plates 21. A first motor 24 is fixedly installed on the side wall of the arc-shaped clamping block 23. A turntable 25 is fixedly sleeved on the rotating shaft of the first motor 24. Two profile conveying cylinders 26 are hinged to the opposite side of the two side plates 21. The first double-headed push rod 22 facilitates the retraction of the two side plates 21, thereby clamping the profile through the two arc-shaped clamping blocks 23. Then, the first motor 24 drives the turntable 25 to rotate, and the turntable 25 drives the profile to rotate synchronously. At the same time, the adjustable double-headed cutting component 4 cuts the profile. When the two side plates 21 retract, the two profile conveying cylinders 26 are opened.

[0032] It should be noted that the turntable 25 can be made of materials with high surface friction, such as rubber, and the outer wall of the turntable 25 is provided with anti-slip texture.

[0033] A limiting block 27 is fixedly provided at the bottom of the side plate 21. The limiting block 27 is located in the slide groove 11 and slides in cooperation with the inner wall of the slide groove 11. The limiting block 27 cooperates with the slide groove 11 to facilitate the limiting of the side plate 21, thereby increasing the stability of the side plate 21 when it moves.

[0034] Both ends of the profile conveying cylinder 26 are hinged with hinge rods 28. The end of the hinge rod 28 away from the profile conveying cylinder 26 is hinged to the side wall of the side plate 21. When the two side plates 21 retract, the hinge rod 28 is folded and pushes the profile conveying cylinder 26 to open, thereby causing the profile groove to separate from the profile conveying cylinder 26. Then, the profile is limited by the arc-shaped locking block 23. At this time, the first motor 24 drives the turntable 25 to rotate to control the rotation of the profile. When the two side plates 21 expand, the hinge rod 28 is unfolded and pulls the two profile conveying cylinders 26 to retract, thereby clamping the profile through the profile conveying cylinder 26 to facilitate the conveying of the profile.

[0035] The profile conveying cylinder 26 includes two circular plates 261 and a rubber column 262. The rubber column 262 is rotatably disposed between the two circular plates 261. An annular groove 263 is provided on the outer wall of the rubber column 262. A second motor 264 is fixedly disposed on the side wall of the circular plates 261. The second motor 264 is fixedly connected to one end of the rubber column 262. The second motor 264 facilitates the rotation of the rubber column 262. As the rubber column 262 rotates, it facilitates the conveying of the profile, so as to facilitate the continuous cutting of the profile.

[0036] A blocking frame 5 is fixedly installed on the inner bottom wall of the frame 1. A detection probe 6 is installed at the bottom of the adjustable double-headed cutter 4. The adjustable double-headed cutter 4 includes a second double-headed push rod 41 and two fixed frames 42. The second double-headed push rod 41 is fixedly installed at the extended end of the electric push rod 3. The two fixed frames 42 are respectively fixedly installed at both ends of the second double-headed push rod 41. A telescopic rod 43 is installed between the two fixed frames 42. Each of the two fixed frames 42 is equipped with a cutting head 44, and the two cutting heads 44 are of different sizes. The detection probe 6 is located at the bottom of the fixed frame 42 above the blocking frame 5. The detection probe 6 is installed through the second double-headed push rod 41. 1. The distance between the two fixed frames 42 and the two cutting heads 44 can be adjusted, and the stability of the two fixed frames 42 during movement is increased by the telescopic rod 43. One of the two cutting heads 44 is an FRP profile saw blade and the other is a steel cutting saw blade. Thus, the steel core of the profile and the FRP material can be cut separately by the two cutting heads 44. When the fixed frame 42 moves down, it causes the detection probe 6 to come into contact with the blocking part. At this time, the detection probe 6 transmits the signal to the electric push rod 3, thereby causing the cutting head 44 to stop moving down, so as to reduce the possibility of the FRP profile saw blade cutting the steel core.

[0037] The blocking frame 5 includes an arc-shaped support plate 51 and two non-metallic core rods 52. The arc-shaped support plate 51 is fixedly installed on the inner bottom wall of the frame 1. The two non-metallic core rods 52 are symmetrically arranged on the top of the arc-shaped support plate 51. A discharge port 53 is provided in the arc-shaped support plate 51. The non-metallic core rods 52 are made of wood, plastic or fiberglass. The two non-metallic core rods 52 work together with the detection probe 6 to reduce the possibility of the FRP profile saw blade cutting the steel core. The arc-shaped support plate 51 facilitates the support of the profile, and the discharge port 53 facilitates the discharge of the cutting debris.

[0038] Working principle: When using this steel-core reinforced FRP pultruded profile cutting equipment, the profile is first conveyed to the adjustable double-headed cutter 4 by the profile conveyor 2. Then, the adjustable double-headed cutter 4 is pushed down by the electric push rod 3 to cut the profile. One of the blades of the adjustable double-headed cutter 4 cuts the FRP on the outside of the profile. At the same time, the blocking frame 5 blocks the adjustable double-headed cutter 4 to reduce the possibility of the adjustable double-headed cutter 4 directly cutting the steel core. The other blade of the adjustable double-headed cutter 4 cuts the steel core, thereby realizing the separate cutting of the steel-core reinforced FRP pultruded profile, reducing the increase of blade wear, and reducing the possibility of burning and blackening of the FRP part on the profile.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
