Description

Technical Field

[0001] This utility model relates to the field of angle steel processing technology, specifically to an angle steel back-shoveling machine. Background Technology

[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. It is divided into equal-sided angle steel and unequal-sided angle steel. Equal-sided angle steel has two sides of equal width. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connecting parts between components. It is widely used in various building structures and engineering structures, such as roof beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses. When processing the back of angle steel, an angle steel backing machine is usually used.

[0003] As disclosed in the patent announcement CN212443559U, a back-shovel machine for angle steel production includes a support mechanism for the support device, a collection mechanism for collecting debris, and a back-shovel mechanism. The collection mechanism is installed on the support mechanism, and the back-shovel mechanism is fixed above the support mechanism. The beneficial effects of this invention are: by setting up the collection mechanism, debris generated by the back-shovel can be collected, preventing debris from scattering and polluting the environment.

[0004] While the aforementioned patent facilitates the collection of waste, some of the debris generated during the processing of angle steel remains on the horizontal plate and cannot be processed. This necessitates manual cleaning of the debris from the horizontal plate by workers later on. Utility Model Content

[0005] The purpose of this utility model is to provide an angle steel back-shovel machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An angle steel back-shovel machine, including

[0008] The processing box has a material discharge chute at its bottom.

[0009] A transmission housing is fixedly installed on the top of the processing box, a reciprocating mechanism is provided inside the transmission housing, and a shovel mechanism is provided below the reciprocating mechanism.

[0010] A support plate is movably installed inside the lower part of the processing box. Clamping mechanisms are provided at the four corners of the top of the support plate. A flipping mechanism is provided between the support plate and the processing box.

[0011] Preferably, the reciprocating mechanism includes a servo motor, which is located inside one end of the transmission housing. The output shaft of the servo motor is fixedly connected to a reciprocating lead screw, and a movable frame is movably mounted on the outside of the reciprocating lead screw. A guide groove matching the movable frame is provided between the transmission housing and the middle of the processing box.

[0012] Preferably, the back-shovel mechanism includes an electric push rod, which is fixedly installed at the bottom of the movable frame. The output shaft end of the electric push rod is provided with a shovel blade, and the top center of the support plate is provided with a triangular protrusion that matches the shovel blade.

[0013] Preferably, the clamping mechanism includes a bracket, which is disposed at the top four corners of the support plate, and a lifting cylinder is fixedly installed at the top of the bracket, and an inclined block is fixedly installed on the output shaft of the lifting cylinder;

[0014] Preferably, the flipping mechanism includes a rotary cylinder, which is disposed inside one side of the processing box. Fixed seats are provided on both sides of the bottom center of the support plate, and the output shaft of the rotary cylinder is fixedly connected to the two fixed seats.

[0015] Preferably, clamping cylinders are also provided on both sides below the center of the processing box near the support plate, and the output shafts of the two clamping cylinders are provided with stop rods, the ends of which are movably located below the center of the support plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This type of angle steel back-shoveling machine uses a rotary cylinder, a fixed seat, a support plate, and a triangular protrusion in cooperation. After the angle steel is processed, two clamping cylinders are activated. The two clamping cylinders simultaneously control the stop bar to retract from the lower center of the support plate. Then, the rotary cylinder is activated, which drives the fixed seat to rotate the support plate 180° and then stops. At this time, the metal debris remaining on the surface of the support plate and the triangular protrusion falls due to its own gravity and is discharged from the discharge chute below the processing box. This can avoid debris residue during cleaning.

[0018] 2. This type of angle steel back-shoveling machine uses a movable frame, an electric push rod, and a shovel in cooperation to clamp the angle steel onto the top of a support plate and a triangular protrusion. Then, the electric push rod is activated, which controls the shovel to descend and abut against the upper end face of one side of the angle steel. At this time, the servo motor is activated, and the servo motor drives the movable frame to move horizontally through a reciprocating screw, thereby controlling the shovel to process along the back of the angle steel. Since an electric push rod is set between the movable frame and the shovel, it is convenient to process angle steel of different thicknesses. Attached Figure Description

[0024] 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.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] An angle steel back-shoveling machine includes a processing box 1 with a feeding chute at its bottom. A transmission housing 2 is fixedly installed at the top of the processing box 1, and a reciprocating mechanism is arranged inside the transmission housing 2. A back-shoveling mechanism is arranged below the reciprocating mechanism. The reciprocating mechanism includes a servo motor 4, which is located at one end inside the transmission housing 2. The output shaft of the servo motor 4 is fixedly connected to a reciprocating lead screw 5, and a movable frame 6 is movably installed outside the reciprocating lead screw 5. A guide groove matching the movable frame 6 is provided between the transmission housing 2 and the middle of the processing box 1. The groove is movably connected to the movable frame 6, which allows the movable frame 6 to move horizontally back and forth, serving as a guide. The back-shoveling mechanism includes an electric push rod 7, which is fixedly installed at the bottom of the movable frame 6. The output shaft end of the electric push rod 7 is provided with a shovel 8, and the top center of the support plate 3 is provided with a triangular protrusion 9 that matches the shovel 8. The clamping mechanism includes a bracket 10, which is located at the four corners of the top of the support plate 3. The top of the bracket 10 is fixedly installed with a lifting cylinder 11, and the output shaft of the lifting cylinder 11 is fixedly installed with an inclined block 12.

[0027] In this embodiment, during processing, the angle steel to be scraped is placed on the triangular protrusion 9 at the top of the support plate 3, and then the lifting cylinder 11 is activated. The lifting cylinder 11 controls the inclined block 12 to descend, clamping the angle steel on the top of the support plate 3 and the triangular protrusion 9. Then, the electric push rod 7 is activated, and the electric push rod 7 controls the scraper 8 to descend and abut against the upper end face of one side of the angle steel. At this time, the servo motor 4 is activated, and the servo motor 4 drives the movable frame 6 to move horizontally by driving the reciprocating screw 5, thereby controlling the scraper 8 to process along the back of the angle steel. Since the electric push rod 7 is set between the movable frame 6 and the scraper 8, it is convenient to process angle steel of different thicknesses.

[0028] like Figure 2 As shown, a support plate 3 is movably installed inside the lower part of the processing box 1. Clamping mechanisms are provided at the four corners of the top of the support plate 3. A flipping mechanism is provided between the support plate 3 and the processing box 1. The flipping mechanism includes a rotary cylinder 13, which is located inside one side of the processing box 1. Fixed seats 14 are provided on both sides of the bottom center of the support plate 3. The output shaft of the rotary cylinder 13 is fixedly connected to the two fixed seats 14. Clamping cylinders 15 are also provided on both sides of the lower part of the processing box 1 near the center of the support plate 3. Stop rods 16 are provided on the output shafts of the two clamping cylinders 15, and the ends of the stop rods 16 are movably located below the center of the support plate 3.

[0029] In this embodiment, after the angle steel is processed, two clamping cylinders 15 are activated. The two clamping cylinders 15 simultaneously control the stop bar 16 to retract from the lower center of the support plate 3. Then, the rotating cylinder 13 is activated. The rotating cylinder 13 drives the fixed seat 14 to drive the support plate 3 to rotate 180° and then stop. At this time, the metal debris remaining on the surface of the support plate 3 and the triangular protrusion 9 falls due to its own gravity and is discharged from the discharge chute below the processing box 1. In this way, debris residue can be avoided during cleaning.

[0030] Working principle: During processing, the angle steel to be scraped is placed on the triangular protrusion 9 at the top of the support plate 3. Then, the lifting cylinder 11 is activated, which controls the inclined block 12 to descend, clamping the angle steel on the support plate 3 and the top of the triangular protrusion 9. Then, the electric push rod 7 is activated, which controls the scraper 8 to descend and abut against the upper end face of one side of the angle steel. At this time, the servo motor 4 is activated, which drives the movable frame 6 to move horizontally through the reciprocating screw 5, thereby controlling the scraper 8 to process along the back of the angle steel. After the angle steel is processed, the two clamping cylinders 15 are activated, which simultaneously control the stop bar 16 to retract from the lower middle part of the support plate 3. Then, the rotating cylinder 13 is activated, which drives the fixed seat 14 to drive the support plate 3 to rotate 180° and then stop. At this time, the metal debris remaining on the surface of the support plate 3 and the triangular protrusion 9 falls due to its own gravity and is discharged from the discharge chute below the processing box 1.
