Description

Technical Field

[0001] This utility model relates to the field of enamel steel shearing, and more specifically, to an anti-burr shearing device for enamel steel. Background Technology

[0002] Enameled steel is made by applying a ceramic enamel coating to the surface of steel plates. This prevents the steel plates from rusting, prevents the formation of an oxide layer on the surface when the steel plates are heated, and resists the corrosion of various liquids. The ceramic enamel coating on the metal blank exhibits excellent properties such as high hardness, high temperature resistance, wear resistance, and insulation, which makes enamel products have a wider range of applications.

[0003] In the prior art, CN222660290U discloses a steel plate shearing machine. Although the above-mentioned prior art realizes the shearing and collection of steel plates, in actual use, due to the plasticity of enamel steel, the blade directly rubs against the edge of the material during shearing, which easily produces severe metal extrusion and tearing. Moreover, the friction between the blade and the material during shearing generates a lot of heat, and the debris generated during shearing is prone to thermal adhesion, which leads to accelerated blade wear and a shortened blade dulling cycle. At the same time, burrs are more likely to be generated in the subsequent shearing process of enamel steel, which greatly affects the shearing quality of enamel steel. In view of this, we propose an anti-burr shearing device for enamel steel to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that some current steel plate shearing devices have poor anti-burr effect when shearing enamel steel.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides an anti-burr shearing device for enamel steel, comprising a base, a collection box on the upper surface of the base, a placement plate fixedly connected to the upper surface of the base, a mounting frame fixedly connected to the upper surface of the placement plate, a shearing blade on the lower side of the horizontal plate of the mounting frame, a hydraulic cylinder fixedly connected to the upper surface of the mounting frame, the telescopic end of the hydraulic cylinder slidingly penetrating through the lower surface of the horizontal plate of the mounting frame and fixedly connected to the shearing blade, and two first fixing plates fixedly connected to the adjacent surfaces of the two vertical plates on both sides of the mounting frame. The fixing plates are located on both sides of the shearing blade. The interior of the first fixing plate is hollow. Three through slots communicating with the interior of the first fixing plate are opened on the surface of the first fixing plate. Atomizing nozzles extending into the interior of the first fixing plate are arranged in the interior of each of the three through slots. Three mounting shafts are rotatably connected to the bottom wall of the interior of the first fixing plate. The three mounting shafts are fixedly connected to the three atomizing nozzles respectively. The upper side of each of the three atomizing nozzles is fixedly connected to a first connecting pipe. The first connecting pipes communicate with the interior of the atomizing nozzles. A drive assembly is arranged outside the mounting shafts. A supply assembly is arranged outside the mounting frame.

[0006] As a preferred technical solution of this application, the drive assembly includes three transmission gears, which are respectively fixedly sleeved on the outside of three mounting shafts. A movable plate is slidably connected inside the first fixed plate. The movable plate has a toothed groove on the side surface facing the transmission gear, and the toothed groove and the movable plate are fixedly connected.

[0007] As a preferred technical solution of this application, an electric push rod is provided inside the first fixed plate, and the telescopic end of the electric push rod is fixedly connected to the moving plate.

[0008] As a preferred technical solution of this application, the supply component includes two storage boxes, both of which are fixedly connected to the surface of the mounting frame. Two pump bodies are fixedly connected to the upper surface of the mounting frame. The input ends of the two pump bodies are respectively connected to the two storage boxes, and the output ends of the pump bodies are fixedly connected to a second connecting pipe.

[0009] As a preferred technical solution of this application, three third connecting pipes are fixedly connected to the surface of the second connecting pipe. All three third connecting pipes are fixedly extended through the lower surface of the mounting bracket cross plate, and the lower ends of the three third connecting pipes are respectively connected to the three first connecting pipes.

[0010] As a preferred technical solution of this application, two second fixing plates are fixedly connected between the two vertical plates on both sides of the mounting frame. The two second fixing plates are respectively located on both sides of the shearing blade. The interior of the second fixing plate is also hollow. An opening is provided on the surface of the second fixing plate facing the shearing blade. The opening and the interior of the second fixing plate are connected.

[0011] As a preferred technical solution of this application, a dust collection box is fixedly connected to the outside of the mounting frame, and two fans are fixedly connected to the upper side of the dust collection box. The output ends of the two fans are connected to the inside of the dust collection box, and the input ends of the two fans are fixedly connected to suction pipes.

[0012] As a preferred technical solution of this application, the ends of the two suction pipes away from the fan both penetrate into the interior of the mounting frame, and the two suction pipes are respectively fixedly connected to the two second fixing plates and communicate with the interior of the second fixing plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. By coordinating the storage tank, pump body, second connecting pipe, third connecting pipe, and first connecting pipe, the lubricant is sprayed from the atomizing nozzle onto the surface of the shearing tool. Simultaneously, the coordination between the electric push rod, moving plate, toothed groove, and transmission gear enables the atomizing nozzle to oscillate, thereby increasing the spray range and reducing the number of nozzles. The sprayed lubricant forms a uniform lubricating film on the cutting edge, providing effective lubrication for the next shearing operation. This significantly reduces metal compression and tearing. Furthermore, the lubricant acts on the cutting edge immediately after shearing, promptly removing residual heat and effectively reducing burr formation during subsequent shearing processes, achieving burr prevention.

[0016] 2. Through the cooperation of the second fixing plate, the through-hole, the fan and other structures, the debris on the surface of the shearing tool is cleaned, which effectively improves the adhesion of the subsequent lubricant. At the same time, it ensures the subsequent shearing effect on the enamel steel, avoids the generation of burrs, reduces the wear of the shearing tool, and achieves the purpose of burr prevention.

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A burr-resistant shearing device for enamel steel includes a base 1, a collection box 2 on the upper surface of the base 1, a placement plate 3 fixedly connected to the upper surface of the base 1, a mounting frame 4 fixedly connected to the upper surface of the placement plate 3, a shearing blade 5 on the lower side of the horizontal plate of the mounting frame 4, a hydraulic cylinder 18 fixedly connected to the upper surface of the mounting frame 4, the telescopic end of the hydraulic cylinder 18 slidingly penetrating through the lower surface of the horizontal plate of the mounting frame 4 and fixedly connected to the shearing blade 5, and two first fixing plates 6 fixedly connected to the adjacent side surfaces of the two vertical plates on both sides of the mounting frame 4. The two first fixing plates 6 are located on both sides of the shearing blade 5, and the two first fixing plates 6 have the same structure, hence the following description... The description focuses on a first fixed plate 6. The interior of the first fixed plate 6 is hollow. Three through slots 7 are formed on the surface of the first fixed plate 6 and communicate with the interior of the first fixed plate 6. Each of the three through slots 7 is provided with an atomizing nozzle 9 extending into the interior of the first fixed plate 6. Three mounting shafts 8 are rotatably connected to the bottom wall inside the first fixed plate 6. The three mounting shafts 8 are fixedly connected to the three atomizing nozzles 9 respectively. The upper side of each of the three atomizing nozzles 9 is fixedly connected to a first connecting pipe 10, which communicates with the interior of the atomizing nozzle 9. A drive assembly is provided on the outside of the mounting shafts 8, and a supply assembly is provided on the outside of the mounting bracket 4.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the drive assembly includes three transmission gears 11, which are respectively fixedly sleeved on the outside of three mounting shafts 8. A movable plate 12 is slidably connected inside the first fixed plate 6. The movable plate 12 has a toothed groove 13 on the side surface facing the transmission gears 11. The toothed groove 13 and the movable plate 12 are fixedly connected. By moving the movable plate 12, the mounting shafts 8 can be rotated under the cooperation of the toothed groove 13 and the transmission gears 11. The rotation of the mounting shafts 8 can drive the atomizing nozzle 9 to swing inside the through groove 7, thereby increasing the spray range.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an electric push rod 14 is provided inside the first fixed plate 6. The telescopic end of the electric push rod 14 is fixedly connected to the moving plate 12. The moving plate 12 can be driven to slide inside the first fixed plate 6 by starting the electric push rod 14 through an external control component.

[0032] In the above embodiments, the electric push rod 14 is also equipped with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail here.

[0033] Example 2

[0034] The anti-burr shearing device for enamel steel provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the supply assembly includes two storage tanks 15 for storing lubricating fluid. Both storage tanks 15 are fixedly connected to the surface of the mounting bracket 4. Two pump bodies 16 are fixedly connected to the upper surface of the mounting bracket 4. The input ends of the two pump bodies 16 are connected to the two storage tanks 15 respectively through pipes. The output end of the pump body 16 is fixedly connected to a second connecting pipe 17. By starting the pump body 16 through an external control component, the lubricating fluid inside the storage tank 15 can be drawn into the second connecting pipe 17, thereby facilitating the flow of lubricating fluid.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, three third connecting pipes 24 are fixedly connected to the surface of the second connecting pipe 17. All three third connecting pipes 24 are fixedly extended through the lower surface of the horizontal plate of the mounting bracket 4. The lower ends of the three third connecting pipes 24 are respectively connected to the three first connecting pipes 10 through rotating flanges. When the atomizing nozzle 9 swings, the atomizing nozzle 9 will drive the first connecting pipe 10 to rotate. At this time, under the action of the rotating flange, the third connecting pipes 24 will not be driven to rotate, thus effectively ensuring the flow efficiency of the lubricating fluid.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, two second fixing plates 19 are fixedly connected between the two vertical plates on both sides of the mounting bracket 4. The two second fixing plates 19 are located on both sides of the shearing blade 5. The two second fixing plates 19 have the same structure, so the following description focuses on one second fixing plate 19. The interior of the second fixing plate 19 is also hollow. A through-hole 20 is opened on the surface of the second fixing plate 19 facing the shearing blade 5. The through-hole 20 is connected to the interior of the second fixing plate 19.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a dust collection box 22 is fixedly connected to the outside of the mounting bracket 4. Two fans 23 are fixedly connected to the upper side of the dust collection box 22. The output ends of the two fans 23 are connected to the inside of the dust collection box 22. The input ends of the two fans 23 are fixedly connected to suction pipes 21.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the ends of the two suction pipes 21 away from the fan 23 both penetrate into the interior of the mounting bracket 4. The two suction pipes 21 are fixedly connected to the two second fixing plates 19 respectively and are connected to the interior of the second fixing plates 19. By starting the fan 23, the debris attached to the surface of the shearing blade 5 can be sucked into the interior of the second fixing plate 19 through the opening 20 by the negative pressure, and then the debris is collected in the interior of the dust collection box 22.

[0039] The usage process of the anti-burr shearing device for enamel steel provided by this utility model is as follows:

[0040] The worker places the enamel steel to be sheared on the placement plate 3, and then starts the hydraulic cylinder 18 to drive the shearing blade 5 downward, thereby shearing the enamel steel.

[0041] After shearing is completed, as the hydraulic cylinder 18 drives the shearing blade 5 to rise, when the shearing blade 5 rises between the two second fixed plates 19, the fan 23 can be started to draw the debris attached to the surface of the shearing blade 5 into the interior of the second fixed plate 19 through the opening 20 by using negative pressure, and then collect the debris in the dust collection box 22.

[0042] Subsequently, when the shearing blade 5 rises between the two first fixed plates 6, the pump body 16 can be activated by the external control component to draw the lubricant inside the storage tank 15 into the interior of the second connecting pipe 17, thereby facilitating the flow of lubricant. The lubricant will then pass through the interior of the second connecting pipe 17, the third connecting pipe 24 and the first connecting pipe 10 and be sprayed out from the interior of the atomizing nozzle 9.

[0043] Simultaneously, the electric push rod 14 can be activated and its telescopic end can be moved back and forth. Activating the electric push rod 14 via the external control component can drive the moving plate 12 to slide inside the first fixed plate 6. The movement of the moving plate 12, in cooperation with the toothed groove 13 and the transmission gear 11, can drive the mounting shaft 8 to rotate. The rotation of the mounting shaft 8 can drive the atomizing nozzle 9 to swing inside the through groove 7, thereby increasing the spray range and ultimately spraying the lubricant onto the surface of the shearing tool 5.
