Description

Technical Field

[0001] This invention relates to the field of cable tray processing technology, and more specifically to a fully automatic metal cutting device for cable tray processing. Background Technology

[0002] Cable trays (also known as cable bridges) are core support equipment used in computer rooms, base stations, and other places for the systematic laying and management of optical cables and electrical cables. They are mainly used in telecommunications, network communication, broadcasting, data centers, and other fields. During the processing of cable trays, a relatively wide steel strip needs to be cut first. During the cutting process, friction occurs at the contact point between the steel strip and the cutting blade, which causes rapid heating. The combined effect of thermal coupling and mechanical plastic deformation leaves residual stress on the steel strip.

[0003] These residual stresses can affect the fatigue strength and stress corrosion resistance of the cable tray during bending and use, thus reducing its service life. Summary of the Invention

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a fully automatic metal cutting equipment for cable tray processing, which can effectively solve the problem that residual stress is generated during the cutting process of cable trays in the existing technology. These residual stresses will affect the fatigue strength and stress corrosion resistance of the cable tray during bending processing and use, and reduce the service life of the cable tray during use.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides a fully automatic metal cutting device for cable tray processing, including a cutting table and a cutting box fixedly installed above the cutting table. A cutting motor is provided on the side of the cutting box, a cutting groove is provided on the cutting table, the cutting box is located directly above the cutting groove, and a cutting shaft is rotatably installed inside the cutting box. Multiple cutting blades are fixedly installed on the cutting shaft at intervals.

[0009] It also includes a shot peening component, which includes a shot peening box fixedly installed on the cutting table. The cut steel strip passes through the shot peening box. An adjusting frame is rotatably installed inside the shot peening box. Multiple shot peening guns are installed at intervals on the adjusting frame. The lower outlet of the shot peening gun is directly opposite the cutting groove on the steel strip.

[0010] Furthermore, multiple limiting rollers are rotatably mounted on the cutting table. These limiting rollers are used to press the steel strip onto the cutting table. One set of limiting rollers is connected to the cutting shaft and is used to drive the steel strip to move into the cutting box.

[0011] Furthermore, a shot peening groove is provided on the cutting table. The shot peening groove is located directly below the shot peening component. A feeding space is formed between the bottom of the shot peening groove and the steel strip. The shot propelled by the shot peening gun enters the feeding space through the cutting gap of the steel strip.

[0012] Furthermore, a collection box is provided below the cutting table, the collection box has an opening at the top, and a rectangular through hole is provided at the bottom of the shot peening groove, with the collection box fixedly installed inside the rectangular through hole.

[0013] Furthermore, the shot peening box has an opening on the side away from the cutting box, and an L-shaped plate is fixedly installed at the opening. The L-shaped plate and the side guards of the shot peening box form a closed space. The closed space is connected to the interior of the shot peening box, and a moving component for moving residual shot on the steel strip is provided inside the closed space.

[0014] Furthermore, the two side guard plates of the shot peening box are directly rotatably mounted with drive shafts, and multiple drive slots are spaced apart on the outer side of the drive shafts. The actuating assembly includes multiple sliding shafts slidably mounted on the L-shaped plate. The upper part of the sliding shafts is inserted into the drive slots. During the rotation of the drive shaft, the drive slots drive the sliding shafts to slide left and right.

[0015] Furthermore, a toggle plate is fixedly installed below each of the sliding shafts. The upper part and the end away from the cutting box of the toggle plate are closely attached to the inner wall of the L-shaped plate and are slidably connected to the inner wall of the L-shaped plate. The lower part of the toggle plate is closely attached to the upper end face of the steel strip. During the left and right sliding process of the toggle plate, the residual shot on the steel strip is driven into the cutting gap of the steel strip and falls into the shot peening groove.

[0016] Furthermore, one end of the cutting shaft is connected to the drive shaft via a transmission belt, and the drive shaft rotates synchronously during the rotation of the cutting shaft.

[0017] Furthermore, the adjusting frame is provided with multiple mounting slots, which are correspondingly positioned above the cutting gaps of multiple steel strips. The shot peening gun is fixedly installed inside the mounting slots, and the upper end of the shot peening gun is connected to the main body of the shot peening equipment through a flexible hose. By providing multiple mounting slots on the adjusting frame, multiple shot peening guns can be detachably fixed on the adjusting frame. The adjusting frame is rotatably mounted on the shot peening box. By rotating the adjusting frame, multiple shot peening guns can be rotated, and the angle of the shot peening guns toward the steel strips can be adjusted.

[0018] Beneficial effects

[0019] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0020] 1. In this invention, multiple cutting blades are rotated and installed inside the cutting box. As the steel strip is continuously fed into the cutting box, the multiple cutting blades cut the steel strip into several narrow strips. On the other hand, by setting a shot peening component on one side of the cutting box, the cut steel strip can be shot peened to eliminate surface stress at the cut point and to perform shot peening and grinding on the cut seam to eliminate burrs. This allows for fast and efficient cutting of the steel strip, preventing potential hazards from being left in the processing or use of the cable tray steel strip.

[0021] 2. In this invention, by setting an L-shaped plate on one side of the shot peening box, the L-shaped plate is relatively low, so that the shot that is splashed into the L-shaped plate has only a small space to jump, so that the splashed shot stops falling onto the surface of the steel strip quickly. By rotating and installing a drive shaft at one end of the shot peening box, the drive groove on the drive shaft will drive the sliding shaft to slide left and right on the L-shaped plate during the rotation, so that the actuating component can actuate the shot that falls onto the surface of the steel strip to fall into the shot peening groove through the gap of the steel strip.

[0022] 3. In this invention, by setting a toggle plate below the sliding shaft, when the sliding shaft swings left and right, the toggle plate swings left and right with the sliding shaft. During the left and right swinging process, the toggle plate will push the projectiles that fall on the surface of the steel strip into the cutting gap of the steel strip. By using a transmission belt to make the cutting shaft drive the drive shaft to rotate, not only can the cutting shaft and the drive shaft be controlled synchronously, but also the electrical control equipment can be reduced and the failure rate of the equipment can be reduced.

[0023] 4. In this invention, by setting multiple mounting slots on the adjusting frame, multiple shot peening guns can be detachably fixed on the adjusting frame. The adjusting frame is rotatably mounted on the shot peening box. By rotating the adjusting frame, multiple shot peening guns can be rotated, and the angle of the shot peening guns toward the steel strip can be adjusted.

[0024] 5. In this invention, by setting a toggle plate below the sliding shaft, when the sliding shaft swings left and right, the toggle plate swings left and right with the sliding shaft. During the left and right swinging process, the toggle plate will push the projectiles that fall on the surface of the steel strip into the cutting gap of the steel strip. By using a transmission belt to make the cutting shaft drive the drive shaft to rotate, not only can the cutting shaft and the drive shaft be controlled synchronously, but also the electrical control equipment can be reduced and the failure rate of the equipment can be reduced.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] The present invention will be further described below with reference to embodiments.

[0040] Therefore, this invention provides a fully automatic metal cutting device for cable tray processing. Its purpose is at least to perform shot peening on the cut steel strip 5 to eliminate surface stress at the cut point of the steel strip 5, and to perform shot peening and grinding on the cut gap of the steel strip 5 to eliminate burrs at the cut gap, thereby completing the cutting process of the steel strip 5 quickly and efficiently.

[0041] Example: A fully automatic metal cutting device for cable tray processing, such as... Figure 1 - Figure 6 As shown, it includes a cutting table 1 and a cutting box 2 fixedly installed above the cutting table 1. A cutting motor 21 is provided on the side of the cutting box 2. A cutting groove 101 is provided on the cutting table 1. The cutting box 2 is located directly above the cutting groove 101. A cutting shaft 23 is rotatably installed inside the cutting box 2. Multiple cutting blades 22 are fixedly installed on the cutting shaft 23 at intervals.

[0042] It also includes a shot peening component 3, which includes a shot peening box 31 fixedly installed on the cutting table 1. The cut steel strip 5 passes through the shot peening box 31. An adjusting frame 32 is rotatably installed inside the shot peening box 31. Multiple shot peening guns 36 are installed at intervals on the adjusting frame 32. The lower outlet of the shot peening gun 36 is directly opposite the cutting groove 101 on the steel strip 5.

[0043] In this invention, multiple cutting blades 22 are rotatably installed inside the cutting box 2. As the steel strip 5 is continuously fed into the cutting box 2, the multiple cutting blades 22 cut the steel strip 5 into several narrow strips. On the other hand, by setting a shot peening component 3 on one side of the cutting box 2, the cut steel strip 5 can be shot peened to eliminate the surface stress at the cut point of the steel strip 5, and the cut gap of the steel strip 5 can be shot peened and polished to eliminate the burrs at the cut gap. The cutting process of the steel strip 5 is completed quickly and efficiently, avoiding the residual stress of the steel strip 5 affecting the processing of the cable tray during the subsequent processing.

[0044] It should be noted that an annealing component 4 is provided on the side of the shot peening component 3 away from the cutting box 2. By annealing the cut steel strip 5, the steel strip 5 can be stress-relieved as a whole, thus avoiding residual stress inside the cut steel strip 5.

[0045] Furthermore, such as Figure 3 and Figure 4 As shown, multiple limiting rollers 25 are rotatably mounted on the cutting table 1. The multiple limiting rollers are used to press the steel strip 5 onto the cutting table 1. One set of limiting rollers 25 is connected to the cutting shaft 23 for transmission. This set of limiting rollers 25 is used to drive the steel strip 5 to move into the cutting box 2.

[0046] In this design, by setting limiting rollers 25 on both sides of the cutting box 2 of the cutting table 1, the steel strip 5 passes between the cutting table 1 and the limiting rollers 25 during use. The limiting rollers 25 can press the steel strip 5 tightly onto the surface of the cutting table 1, making the curved steel strip 5 straighter and easier to cut. One set of limiting rollers 25 is connected to the cutting shaft 23. During the rotation of the cutting shaft 23, the limiting rollers 25 can be driven to rotate, which can make the limiting shaft 25 drive the steel strip 5 to move, making the steel strip 5 move more smoothly on the cutting table 1.

[0047] In addition, in actual use, a conveying roller is provided at the front end of the cutting table 1 to convey the steel strip 5. The conveying roller is used to drive the steel strip 5 to move on the cutting table 1, so that the steel strip 5 can be continuously conveyed to the cutting blade 22.

[0048] Furthermore, such as Figure 4 and Figure 5 As shown, a shot peening groove 102 is provided on the cutting table 1. The shot peening groove 102 is located directly below the shot peening component 3. A feeding space is formed between the bottom of the shot peening groove 102 and the steel strip 5. After the shot passes through the cutting gap of the steel strip 5, it will fall into the feeding space. The shot ejected by the shot peening gun 36 enters the feeding space through the cutting gap of the steel strip 5. A collection box 35 is provided below the cutting table 1. The collection box 35 has an opening at the top. A rectangular through hole is provided at the bottom of the shot peening groove 102. The collection box 35 is fixedly installed inside the rectangular through hole.

[0049] In this design, a shot peening groove 102 is provided on the cutting table 1, so that a gap is formed between the bottom of the shot peening groove 102 and the steel strip 5. This allows the shot that is shot out downward by the shot peening gun 36 to fall into the interior of the shot peening groove 102 after passing through the gap in the steel strip 5. By providing a collection box 35 below the shot peening groove 102, the shot can be collected conveniently, allowing the shot to be reused.

[0050] Furthermore, such as Figure 5 and Figure 6As shown, the shot peening box 31 has an opening on the side away from the cutting box 2. An L-shaped plate 33 is fixedly installed at the opening. The L-shaped plate 33 and the side guards of the shot peening box 31 form a closed space. A space is reserved between the cutting table 1 below the L-shaped plate 33 and the L-shaped plate 33 for the steel strip 5 to pass through. The gap between the L-shaped plate 33 and the cutting table 1 is just enough for the steel strip 5 to pass through. The closed space is connected to the interior of the shot peening box 31. An actuating component for actuating residual shot on the steel strip 5 is provided inside the closed space. The side guards of the shot peening box 31 are directly rotatably mounted with drive shafts 34. Multiple drive grooves 3401 are spaced apart on the outer side of the drive shafts 34. The actuating component includes multiple sliding shafts 341 slidably mounted on the L-shaped plate 33. The upper part of the sliding shafts 341 is inserted into the drive grooves 3401. During the rotation of the drive shaft 34, the drive grooves 3401 drive the sliding shafts 341 to slide left and right.

[0051] In this design, an L-shaped plate 33 is installed on one side of the shot peening box 31. The L-shaped plate 33 is relatively low, so that the shot that splashes into the L-shaped plate 33 has only a small space to bounce, which makes the splashed shot stop falling onto the surface of the steel strip 5 quickly. By rotating and installing a drive shaft 34 at one end of the shot peening box 31, the drive groove 3401 on the drive shaft 34 will drive the sliding shaft 341 to slide left and right on the L-shaped plate 33 during the rotation. This allows the actuating component to actuate the shot that falls onto the surface of the steel strip 5 and fall into the shot peening groove 102 through the gaps in the steel strip 5.

[0052] Furthermore, such as Figure 4 and Figure 7 As shown, a deflector plate 342 is fixedly installed below each sliding shaft 341. The height of the deflector plate 342 is the same as the distance from the steel strip 5 to the top inner wall of the L-shaped plate 33, so that the L-shaped plate 33 can abut against the upper edge of the deflector plate 342 to prevent the L-shaped plate 33 from shifting position. The upper part and the end away from the cutting box 2 of the deflector plate 342 are in close contact with the inner wall of the L-shaped plate 33 and are slidably connected to the inner wall of the L-shaped plate 33. The lower part of the deflector plate 342 is in close contact with the upper end face of the steel strip 5. During the left and right sliding process of the deflector plate 342, it drives the residual shot on the steel strip 5 to slide into the cutting gap of the steel strip 5 and fall into the shot peening groove 102. One end of the cutting shaft 23 is connected to the drive shaft 34 through the transmission belt 24. During the rotation of the cutting shaft 23, it drives the drive shaft 34 to rotate synchronously.

[0053] By setting a toggle plate 342 below the sliding shaft 341, when the sliding shaft 341 swings left and right, the toggle plate 342 swings left and right with the sliding shaft 341. During the left and right swinging process, the toggle plate 342 will push the bullets that fall on the surface of the steel belt 5 into the cutting gap of the steel belt 5. By using the transmission belt 24 to drive the cutting shaft 23 to rotate the drive shaft 34, not only can the cutting shaft 23 and the drive shaft 34 be controlled synchronously, but also the electrical control equipment can be reduced and the failure rate of the equipment can be lowered.

[0054] Furthermore, the adjusting frame 32 is provided with a plurality of mounting slots 3201, which are respectively positioned above the cutting gaps of the plurality of steel strips 5. The shot peening gun 36 is fixedly installed inside the mounting slots 3201. The upper end of the shot peening gun 36 is connected to the main body of the shot peening equipment through a flexible hose. The main body of the shot peening equipment (shot blaster, shot blasting gun system (mixing chamber and shot conveying valve)) is a common technology in the prior art and will not be described in detail here.

[0055] By setting multiple mounting slots 3201 on the adjusting frame 32, multiple shot peening guns 36 can be detachably fixed on the adjusting frame 32. The adjusting frame 32 is rotatably mounted on the shot peening box 31. By rotating the adjusting frame 32, multiple shot peening guns 36 can be rotated, and the angle of the shot peening guns 36 toward the steel belt 5 can be adjusted.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
