Description

Technical Field

[0001] This utility model belongs to the field of angle steel plate cutting technology, specifically an angle steel support plate cutting device. Background Technology

[0002] Angle steel is a common building material. As the name suggests, it is a type of steel with an angular cross-section. It is usually formed by hot rolling or cold bending and has good strength and stability. It is widely used in construction, machinery manufacturing, bridge construction and other fields. One of the characteristics of angle steel is its unique cross-sectional shape, which gives it good compressive and torsional resistance when subjected to vertical and horizontal forces. This makes angle steel often used as a support, reinforcement or connection material in building structures. In addition, the smooth and flat surface of angle steel is easy to process and weld, and can meet the needs of different projects.

[0003] In practical applications, angle steel is often used to manufacture various frame structures, such as door and window frames, shelves, and workbenches, due to its strong stability and load-bearing capacity. Secondly, angle steel is also often used as a support and reinforcement material for buildings, such as beam-column connectors and steel structure frames, which can improve the overall stability and safety of buildings. In addition, angle steel is often used to manufacture parts for mechanical equipment, such as angle iron brackets and machine tool beds, which have good load-bearing capacity and wear resistance. Before angle steel is put into use, it needs to be cut as needed to ensure that the angle steel meets the requirements of use.

[0004] Meanwhile, an angle steel cutting device with application number CN202421063672.2 includes a base plate, with support legs fixedly installed at the four corners of the bottom of the base plate. A drive mechanism is fixedly connected to the left side of the top of the base plate via a first telescopic member, and a cutting and grinding mechanism is fixedly installed on the moving end of the drive mechanism. A vertical plate is fixedly installed on the right side of the top of the base plate, and an angle steel placement platform is fixedly installed on the inner side of the vertical plate via a second telescopic member. A pressure plate is fixedly connected to the right side of the top of the angle steel placement platform via a third telescopic member.

[0005] However, the following problems were found in the implementation of the relevant technology: the exposed cutting blade makes it easy to cause injury, and if no blade protection structure is set, the high-speed rotating cutting blade will pose a certain safety hazard. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an angle steel support plate cutting device with a blade protection structure, which has the advantage of avoiding excessive exposure of the cutting blade and thus preventing safety hazards.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for angle steel support plates, including a fixed base, a third drive source connected to the top of the fixed base, a worm gear connected to the power output end of the third drive source, a first support frame connected to the top of the fixed base, a worm wheel rotatably connected to the surface of the first support frame, a second support frame connected to the top of the fixed base, and a drive assembly and a limiting assembly respectively provided on the fixed base;

[0008] The surface of the drive assembly is connected to the surface of the fixed base to drive the drive assembly to rotate around the worm gear as the center.

[0009] The surface of the limiting component is connected to the surface of the driving component to improve stability.

[0010] Preferably, the drive assembly includes a fixed rod, a first drive source, and a protective shell. The fixed rod is disposed on one side of the worm gear, and a fixed plate is connected to the surface of the fixed rod. The first drive source is disposed on the top of the fixed plate, and a connecting plate is connected to the power output end of the first drive source. A connecting rod is connected to the surface of the connecting plate. The protective shell is disposed at one end of the connecting rod, and a second drive source is connected to one side of the protective shell. A cutting blade is connected to the power output end of the second drive source.

[0011] Preferably, one end of the fixing rod is rotatably connected to one side of the second support frame via a bearing.

[0012] Preferably, the limiting component includes a fixing block disposed at the top of the fixing plate, and two limiting slide rods are slidably connected to the inner side of the fixing block.

[0013] Preferably, one end of each of the two limiting slide rods is connected to the surface of the connecting plate.

[0014] Preferably, the movement trajectories of the two limiting slide rods are both horizontal, performing a forward and backward translational motion.

[0015] Preferably, the worm gear is meshed with the worm wheel.

[0016] Preferably, the surface of the worm gear is rotatably connected to the inner side of the first support frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model uses a third drive source to easily drive the worm gear to rotate, which in turn drives the worm wheel that meshes with the worm gear to rotate. This causes the entire fixed rod to tilt forward or backward, allowing the cutting blade to tilt and contact the angle steel to complete the cutting. A protective shell is provided between the cutting blade and the second drive source, thus providing good protection and preventing the cutting blade from being exposed to the air too much, which could create significant safety hazards.

[0019] 2. This utility model uses a first driving source to drive the connecting plate, connecting rod, protective shell, and cutting blade to move back and forth horizontally, thereby adjusting the position of the cutting blade to cut the angle steel at different positions. While the first driving source drives the connecting plate to move horizontally, both limiting slide rods slide inside the fixed block, thereby providing support for the connecting plate, improving the stability of the connecting plate's movement, and helping to improve the stability of the cutting blade in cutting the angle steel, preventing the connecting plate from shaking or shifting.

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.

[0030] like Figures 1 to 5 As shown, this utility model provides a cutting device for angle steel support plates, including a fixed base 1, a third drive source 4 connected to the top of the fixed base 1, a worm gear 5 connected to the power output end of the third drive source 4, a first support frame 6 connected to the top of the fixed base 1, a worm wheel 7 rotatably connected to the surface of the first support frame 6, a second support frame 8 connected to the top of the fixed base 1, and a drive assembly 2 and a limiting assembly 3 respectively provided on the fixed base 1.

[0031] The surface of the drive assembly 2 is connected to the surface of the fixed base 1 so as to drive the drive assembly 2 to rotate around the worm gear 7 as the center.

[0032] The surface of the limiting component 3 is connected to the surface of the driving component 2 to improve stability.

[0033] Specifically, the drive assembly 2 includes a fixed rod 21, a first drive source 23, and a protective shell 26. The fixed rod 21 is disposed on one side of the worm gear 7, and a fixed plate 22 is connected to the surface of the fixed rod 21. The first drive source 23 is disposed at the top of the fixed plate 22, and a connecting plate 24 is connected to the power output end of the first drive source 23. A connecting rod 25 is connected to the surface of the connecting plate 24. The protective shell 26 is disposed at one end of the connecting rod 25, and a second drive source 27 is connected to one side of the protective shell 26. A cutting blade 28 is connected to the power output end of the second drive source 27.

[0034] Furthermore, one end of the fixing rod 21 is rotatably connected to one side of the second support frame 8 via a bearing.

[0035] Furthermore, the limiting component 3 includes a fixing block 31, which is disposed at the top of the fixing plate 22, and two limiting slide rods 32 are slidably connected to the inner side of the fixing block 31.

[0036] It is worth noting that one end of each of the two limiting slide rods 32 is connected to the surface of the connecting plate 24.

[0037] It is worth noting that the movement trajectories of both limiting slide rods 32 are both horizontal, moving back and forth.

[0038] It is worth mentioning that the worm 5 is meshed with the worm wheel 7.

[0039] It is worth emphasizing that the surface of the worm 5 is rotatably connected to the inner side of the first support frame 6.

[0040] Among them, (worm gear 5, worm wheel 7, cutting blade 28) are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0041] Working principle: First, the angle steel is held and placed on the top surface of the fixed base 1. The worm gear 5 is driven to rotate by the third drive source 4, and the cutting blade 28 is driven to rotate by the second drive source 27. At this time, the worm wheel 7, which is meshed with the worm gear 5, rotates, which causes the fixed rod 21 to tilt downward. This causes the entire fixed rod 21, including the first drive source 23 and the cutting blade 28, to tilt forward and downward. Then, the cutting blade 28 tilts and contacts the angle steel to complete the cutting. A protective shell 26 is set between the cutting blade 28 and the second drive source 27, thus providing good protection and preventing the cutting blade 28 from overshooting the angle steel. Excessive exposure to air poses a significant safety hazard. If it is necessary to move the cutting position of the cutting blade 28 back and forth, simply turn on the first drive source 23 and drive the connecting plate 24, connecting rod 25, protective shell 26, and cutting blade 28 to move back and forth horizontally. While the first drive source 23 drives the connecting plate 24 to move horizontally, both limit slide rods 32 will slide inside the fixed block 31, thereby providing support for the connecting plate 24 and the cutting blade 28, improving the stability of the movement of the connecting plate 24 and the cutting blade 28, and helping to improve the stability of the cutting blade 28 in cutting angle steel.
