Description

Technical Field

[0001] The utility model relates to the technical field of shearing machines, and specifically discloses a gate type scrap steel shearing machine. Background Art

[0002] In the process of scrap steel recycling, a shearing machine is needed to cut the scrap steel. The existing scrap steel shearing machine mainly consists of a base, a hydraulic system, a material pressing mechanism and a cutter mechanism. When shearing the scrap steel, the hydraulic system first presses the material pressing mechanism down to fix it, and then presses the cutter down in the hydraulic system to cut the scrap steel.

[0003] For example, the utility model patent with application number 2023207792580 discloses a scrap steel shearing and processing equipment, including a placement table, a cutter assembly and a steel pressing assembly are arranged on one side of the placement table, an electric control box is fixedly installed on one side of the placement table, the electric control box is electrically connected to the cutter assembly, and the electric control box is electrically connected to the steel pressing assembly. When the scrap steel shearing and processing equipment disclosed in the patent shears the scrap steel material, the material is first pressed and fixed by the rotation and pressing action of the steel pressing assembly, and then the cutter assembly is rotated and pressed to cut the material. In addition, in order to reduce the resistance during shearing, the existing scrap steel shearing machine often needs to tilt the blade of the cutter or rotate and press it down from one end. However, the pressing mechanism of the existing shearing machine still uses a combination of a horizontal pressing plate and a hydraulic cylinder. Although it can press the scrap steel down and fix it, some scrap steel is packed in bundles and sent to the bottom of the cutter. This makes the material too concentrated in the middle after being pressed by the horizontal pressing plate and cannot be evenly spread on the table. As a result, no matter what shearing method is used to press the blade down, there is a large shearing resistance. Therefore, the shearing machine has too high a power requirement for the hydraulic cylinder, and the blade is more likely to have a notch. Based on the above-mentioned shortcomings of the existing scrap steel shearing and processing equipment, the present application proposes a gate-type scrap steel shearing machine that can effectively solve the above-mentioned technical problems. Utility Model Content

[0004] The utility model mainly provides a gate type scrap steel shearing machine to solve the problem that the material pressing mechanism of the existing shearing machine cannot solve the problem that the material is too concentrated when pressed and fixed, and cannot be effectively and evenly spread, resulting in excessive shearing resistance.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A gate-type scrap steel shearing machine comprises a feeding platform seat, a vertical gantry is arranged at one end of the upper surface of the feeding platform seat, a first hydraulic cylinder and a second hydraulic cylinder are arranged at the upper end of the gantry, a cutting assembly is arranged at the lower end of the first hydraulic cylinder, and a pressing device is connected to the lower end of the second hydraulic cylinder, and the pressing device comprises a pressing beam, a strip groove is opened on the lower surface of the pressing beam along the length direction, and a horizontal sliding bar is fixedly arranged in the strip groove, moving blocks matching the strip groove are slidably arranged at both ends of the horizontal sliding bar, and supporting springs connected to the side ends of the strip groove or the middle section of the horizontal sliding bar are arranged on the two moving blocks, and each of the moving blocks is rotatably connected with a pressure arm extending out of the strip groove, and the outer ends of the two pressure arms are rotatably connected by a pin shaft and are located directly below the center of the pressing beam.

[0007] As a further arrangement of the above scheme, a conveying groove is opened on the upper surface of the feeding platform seat, a conveying belt is arranged in the conveying groove, the upper end of the conveying belt is arranged flush with the upper surface of the feeding platform seat, and the upper surface of the feeding platform seat is provided with baffles located on the front and rear sides of the conveying belt.

[0008] As a further configuration of the above scheme, the cutting assembly includes a tool holder connected to the lower end of the first hydraulic cylinder, the upper surface of the tool holder is provided with a vertical guide rod vertically penetrating the upper end of the gantry, and the side end of the tool holder is installed with a cutting knife.

[0009] As a further configuration of the above solution, the lower blade portions of the cutting knife are inclined with one edge higher than the other.

[0010] As a further configuration of the above scheme, a discharge port is provided at the end of the feeding platform seat directly below the cutting assembly, and the side wall of the discharge port is aligned with the cutting knife in the upper and lower directions.

[0011] As a further configuration of the above scheme, both ends of the pressing beam are connected with sliding block seats, and vertical sliding rails interacting with the sliding block seats are arranged on both side walls of the gantry.

[0012] Beneficial effects:

[0013] The gate-type scrap steel shearing machine disclosed by the utility model changes the traditional flat-plate type pressing mechanism and adopts a pressing device composed of a pressing beam, a supporting spring, a pressure arm and other components. During the pressing process of the pressing device, the hinged joint of the lower ends of the two pressure arms is located exactly in the middle of the scrap steel. Then, during the continued pressing process, the scrap steel gathered together can be evenly spread to both sides. Finally, when the two pressure arms are pressed into the strip grooves, the scrap steel to be sheared can be evenly spread and pressed and fixed. At this time, a cutting knife with an inclined blade portion can effectively reduce the shearing resistance, so that the requirements of the entire shearing machine on the hydraulic system are not high, and the situation of notches in the cutting knife caused by excessive shearing resistance is avoided, thereby effectively improving the use effect and life of the entire shearing machine.

[0018] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0019] Example 1

[0020] This embodiment 1 discloses a gate type scrap steel shearing machine, Figure 1-4 The main part thereof comprises a feeding platform seat 1, a vertical gantry 2 is arranged at one end of the upper surface of the feeding platform seat 1, a first hydraulic cylinder 3 and a second hydraulic cylinder 4 are arranged at the upper end of the gantry 2, a cutting assembly 5 is arranged at the lower end of the first hydraulic cylinder 3, and a material pressing device 6 is connected to the lower end of the second hydraulic cylinder 4.

[0021] In order to realize the automatic conveying of the scrap steel to be sheared, a conveying groove extending toward one side of the cutting assembly 5 is provided on the upper surface of the feeding platform seat 1, and then a conveying belt 7 is arranged in the conveying groove, and the upper end of the conveying belt 7 is arranged flush with the upper surface of the feeding platform seat 1. In addition, baffles 8 are arranged on the upper surface of the feeding platform seat 1 at the front and rear sides of the conveying belt 7, and the baffles 8 are arranged to prevent the scrap steel from falling from the front and rear sides during the conveying process.

[0022] The key design of this embodiment 1 is the pressing device 6, which includes a pressing beam 601, a strip groove 602 is provided on the lower surface of the pressing beam 601 along the length direction, and a horizontal slide bar 603 is fixedly provided in parallel with the strip groove 602. Moving blocks 604 matching the strip groove 602 are slidably provided at both ends of the horizontal slide bar 603, and support springs 605 are provided on the two moving blocks 604, and then the ends of the corresponding support springs 605 are connected to the side ends of the strip groove 602 or the middle section of the horizontal slide bar 603. In this figure, the ends of the support springs 605 are connected to the middle section of the horizontal slide bar 603. A pressure arm 606 extending out of the strip groove 602 is rotatably connected to each moving block 604, and then the outer ends of the two pressure arms 606 are rotatably connected through a pin shaft, and the connection point of the two is located directly below the center of the pressing beam 601.

[0023] In addition, slider seats 607 are connected to both ends of the pressing beam 601, and vertical slide rails 608 that interact with the slider seats 607 are arranged on the two side walls of the gantry 2. Through the guiding action between the slider seats 607 and the vertical slide rails 608, it can be ensured that under the action of the second hydraulic cylinder 4, the pressing device 6 can move vertically downward stably.

[0024] The cutting assembly 5 in this embodiment 1 includes a knife seat 501 connected to the lower end of the first hydraulic cylinder 3, and the upper surface of the knife seat 501 is provided with a vertical guide rod 502 vertically penetrating the upper end of the gantry 2, and then a downwardly arranged cutting knife 503 is installed at the side end of the knife seat 501. In order to reduce the resistance when shearing the scrap steel, the lower blade of the cutting knife 503 is arranged with one high and one low. Finally, a discharge port 101 is also opened at the end of the feeding platform seat 1 directly below the cutting assembly 5, and the side wall of the discharge port 101 is aligned with the cutting knife 503 up and down.

[0025] When the gate-type scrap steel shearing machine disclosed in the present embodiment 1 shears the scrap steel material, the conveyor belt 7 conveys the material toward one side of the discharge port 101 , so that the end of the scrap steel material extends above the discharge port 101 .

[0026] Next, the second hydraulic cylinder 4 is started to push the pressing beam 601 downward. During the downward movement of the pressing beam 601, the hinges of the two pressure arms 606 first contact the center of the scrap steel. During the continued downward pressure, the scrap steel gathered together can be evenly pressed down and spread out to both sides by the pressure arms 606. At the same time, the hinges of the two pressure arms 606 will distribute the resistance to both sides when encountering resistance, so that the moving block 604 overcomes the action of the supporting spring 605 and moves toward the two ends of the strip groove 602. Finally, when the two pressure arms 606 are pressed into the strip groove 602, the scrap steel to be sheared can be spread out evenly, and after being evenly spread out, it is pressed and fixed, waiting to be cut.

[0027] Finally, the first hydraulic cylinder 3 is started to push the cutting assembly 5 downward. Since the lower blades of the cutting knife 503 are tilted one high and one low, the linear contact mode in the shearing process can be changed to a point contact mode, thereby effectively reducing the resistance to the shearing process of the scrap steel.

[0028] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
