Description

Technical Field

[0001] This utility model relates to the field of angle steel processing technology, and in particular to a back-shovel machine for angle steel processing. Background Technology

[0002] Angle steel is a type of hot-rolled steel with an L-shaped cross-section. It has good mechanical properties and workability and is widely used in building structures. Due to the pressing process, angle steel is prone to burrs and excess metal at right angles. Chiseling can remove these defects, making the cross-section more regular, so as to facilitate subsequent connections.

[0003] When performing back scraping, a back scraping machine is needed. The scraper moves to scrape the angle steel. However, due to the continuous action between the scraper and the angle steel, the temperature in the cutting zone rises, which can easily cause the tool to soften due to high temperature. At the same time, the friction coefficient between the tool and the surface of the angle steel is high, which can easily lead to tool wear and affect the service life of the scraper. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that affect the service life of shovel blades, and to propose a shovel backing machine for angle steel processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a back-shovel machine for processing angle steel, including a support base, a worktable fixedly connected to the upper end of the support base, a hydraulic cylinder connected to the upper end of the worktable via a moving mechanism, a shovel blade fixedly connected to the lower end of the hydraulic cylinder, a housing fixedly connected to the hydraulic cylinder, two first connecting pipes connected to the lower end of the housing via a communicating mechanism, connecting lugs fixedly connected to both sides of the lower end of the hydraulic cylinder, the two first connecting pipes being fixedly connected to the two connecting lugs respectively, the two first connecting pipes being located at both ends of the shovel blade, and angle steel fixed to the worktable via a fixing mechanism.

[0007] Preferably, the moving mechanism includes a worktable, with a lead screw rotatably connected to the upper end of the worktable via a bearing, a motor being driven to one end of the lead screw, the motor being fixedly connected to the worktable, and a lead screw slider being threaded through the lead screw and fixedly connected to a hydraulic cylinder.

[0008] Preferably, a positioning rod is fixedly connected to the worktable, and the positioning rod passes through the lead screw slider.

[0009] Preferably, the communication mechanism includes a second connecting pipe, the upper end of which is connected to the housing, the upper end of which is inserted into the second connecting pipe, and a sealing ring is fixedly connected to the outer wall of the upper end of the first connecting pipe, the sealing ring abutting against the inner wall of the second connecting pipe.

[0010] Preferably, the fixing mechanism includes a double-rod hydraulic cylinder, which is fixedly connected to the tabletop of the workbench, and both ends of the double-rod hydraulic cylinder are fixedly connected to fixing blocks.

[0011] Preferably, a right-angled base is fixedly connected to the tabletop of the workbench.

[0012] Preferably, the workbench has multiple through holes on its surface, and a collection box is placed on the support base, with the collection box located directly below the through holes.

[0013] Preferably, the housing is made of a transparent material.

[0014] The present invention proposes a back-scraping machine for angle steel processing, which has the following advantages: the fluid enters the first connecting pipe through the connecting mechanism and flows into the scraper, which cools the scraper and wets the contact part between the angle steel and the scraper. The lubricating components in the cutting fluid form a lubricating film between the angle steel and the scraper, reducing the coefficient of friction and thus extending the service life of the scraper.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A back-shovel machine for processing angle steel includes a support base 2, a workbench 1 fixedly connected to the upper end of the support base 2, a hydraulic cylinder 15 connected to the upper end of the workbench 1 via a moving mechanism, a shovel blade 16 fixedly connected to the lower end of the hydraulic cylinder 15, a housing 11 fixedly connected to the hydraulic cylinder 15, the housing 11 being made of transparent material to allow observation of the amount of cutting fluid inside the housing 11, and a fluid injection port provided on the housing 11, with a cap threadedly connected to the fluid injection port.

[0023] The lower end of the housing 11 is connected to two first connecting pipes 18 through a connecting mechanism. The lower ends of the hydraulic cylinder 15 are fixedly connected to two connecting ears 13. The two first connecting pipes 18 are fixedly connected to the two connecting ears 13 respectively. The two first connecting pipes 18 are located at both ends of the blade 16. Angle steel 12 is fixed on the worktable 1 through a fixing mechanism. When the blade 16 moves the back of the blade, the cutting fluid in the housing 11 enters the first connecting pipes 18 through the connecting mechanism and flows into the blade 16, which cools the blade 16 and wets the contact part between the angle steel 12 and the blade 16. The lubricating components in the cutting fluid will form a lubricating film between the angle steel 12 and the blade 16, reducing the coefficient of friction and thus extending the service life of the blade 16.

[0024] The moving mechanism includes a worktable 1. A lead screw 7 is rotatably connected to the upper end of the worktable 1 via a bearing. A motor 8 is driven to one end of the lead screw 7. The motor 8 is fixedly connected to the worktable 1. A lead screw slider 9 is threaded through the lead screw 7. The lead screw slider 9 is fixedly connected to the hydraulic cylinder 15. The rotation of the motor 8 drives the lead screw 7 to rotate. The lead screw 7 drives the lead screw slider 9 to move on the lead screw 7, thereby driving the hydraulic cylinder 15 to move, so as to adjust the longitudinal position of the blade 16.

[0025] A positioning rod 10 is fixedly connected to the worktable 1. The positioning rod 10 passes through the lead screw slider 9. The positioning rod 10 is used to limit the lead screw slider 9 and prevent the lead screw slider 9 from rotating.

[0026] Example 2: Refer to Figure 1-5 In another preferred embodiment of this utility model, based on embodiment 1, the connecting mechanism includes a second connecting pipe 19. The upper end of the second connecting pipe 19 is connected to the housing 11. The upper end of the first connecting pipe 18 is inserted into the second connecting pipe 19. A sealing ring 14 is fixedly connected to the outer wall of the upper end of the first connecting pipe 18. The sealing ring 14 abuts against the inner wall of the second connecting pipe 19. When the hydraulic cylinder 15 is extended and retracted, it will drive the first connecting pipe 18 to move in the second connecting pipe 19. The sealing ring 14 plays a sealing role, ensuring the conduction of cutting fluid. Valves are provided on both second connecting pipes 19 to close the cutting fluid.

[0027] Example 3: Reference Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 2, the fixing mechanism includes a double-rod hydraulic cylinder 3, which is fixedly connected to the tabletop of the workbench 1, and both ends of the double-rod hydraulic cylinder 3 are fixedly connected to fixing blocks 4.

[0028] A right-angle placement seat 6 is fixedly connected to the tabletop of the workbench 1. Angle steel 12 is placed on the right-angle placement seat 6. The two ends of angle steel 12 are clamped by fixing block 4 to fix angle steel 12. The length of angle steel 12 is less than 1.5m to prevent the middle of angle steel 12 from bulging when clamped.

[0029] During the back-scraping process, the angle steel 12 is placed on the right-angle placement seat 6. The double-rod hydraulic cylinder 3 retracts, causing the two fixing blocks 4 to clamp and fix the two ends of the angle steel 12. Then, the hydraulic cylinder 15 extends, driving the scraper 16 to descend. The motor 8 rotates, driving the lead screw 7 to rotate. The lead screw 7 drives the lead screw slider 9 to move on the lead screw 7, thereby driving the hydraulic cylinder 15 to move, causing the scraper 16 to move and perform back-scraping treatment on the angle steel 12. At the same time, as the scraper 16 moves, the cutting fluid flows from the first connecting pipe 18 to the scraper 16 to cool it.

[0030] Example 4: Reference Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 3, a plurality of through holes 5 are provided on the tabletop of the workbench 1, and a rectangular frame 17 is fixedly connected to the tabletop of the workbench 1. The plurality of through holes 5 are located inside the rectangular frame 17. The rectangular frame 17 prevents the cutting fluid from flowing out of the workbench 1. A collection box 20 is placed on the support base 2. The collection box 20 is located directly below the through holes 5. The through holes 5 are used to guide the flowing cutting fluid into the collection box 20 for collection.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
