Abstract
Description
Steel plate trimming device Technical Field
[0001] This utility model belongs to the technical field of steel plate edge cutting device, and particularly relates to a steel plate edge cutting device. Background Technology
[0002] In fields such as steel structure production, rough-cut steel plates require precision cutting. Currently used cutting devices include a frame with horizontal support rods, a cutting gun holder mounted on the support rods, and a cutting gun mounted on the holder. Traveling wheels are located below the frame. During cutting, two parallel steel rails are positioned above the steel plate. As the traveling wheels move above the rails, the cutting gun cuts the edges of the steel plate. This method has the following drawbacks: First, before cutting, the rails must be precisely placed above the steel plate for accurate cutting. Because the rails are heavy, placement is labor-intensive and inefficient. Second, errors in rail placement can lead to poor cutting quality and deviations. Third, when not cutting, the rails must be laid flat to prevent bending, which affects cutting quality and occupies a large amount of space. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a steel plate edge cutting device with low labor intensity, small space occupation, high cutting accuracy and high cutting efficiency.
[0004] To solve the above problems, the technical solution adopted by the steel plate trimming device of this utility model is as follows: it includes a frame, a transverse support rod is provided on the frame, a cutting gun frame is provided on the transverse support rod, a cutting gun is provided on the cutting gun frame, a traveling wheel is provided below the frame and is powered by a traveling power mechanism, a side support rod is provided on the side of the frame in front of the transverse support rod, a limit wheel positioning frame is provided on the side support rod, a limit wheel is provided on the limit wheel positioning frame, a guide wheel frame is provided in front of the frame, a guide wheel is provided on the guide wheel frame, and the traveling direction of the guide wheel is biased away from the limit wheel.
[0005] Its additional technical features are:
[0006] The guide wheel is a steering wheel, and a locking mechanism is provided between the guide wheel and the guide wheel frame;
[0007] The limiting wheel positioning frame includes a limiting sleeve and a limiting frame body. The limiting sleeve is fitted onto the side support rod, and a limiting locking mechanism is provided on the limiting sleeve.
[0008] The cutting gun holder includes a cutting sleeve and a cutting frame. The cutting sleeve is fitted onto the transverse support rod, and a cutting locking mechanism is provided on the cutting sleeve.
[0009] Compared with the prior art, the steel plate edge cutting device provided by this utility model has the following advantages: Firstly, it includes a frame with a transverse support rod on it, a cutting gun holder on the transverse support rod, a cutting gun on the cutting gun holder, a traveling wheel connected to the traveling power mechanism at the bottom of the frame, a side support rod on the side of the frame in front of the transverse support rod, a limit wheel positioning frame on the side support rod, a limit wheel on the limit wheel positioning frame, a guide wheel frame in front of the frame, and a guide wheel on the guide wheel frame. The travel direction of the guide wheel is biased away from the limit wheel. Before cutting, an attachment plate with the same width and thickness as the steel plate is placed in front of the steel plate. The length of the attachment plate is slightly greater than the distance from the cutting gun to the front end of the frame, so that the attachment plate is aligned with the steel plate. The steel plate edge cutting device is placed on the steel plate, the limit wheel is attached to the side of the steel plate, and the traveling power mechanism is turned on to drive the traveling wheel to rotate. While the steel plate edge cutting device moves forward, the cutting gun cuts the edge of the steel plate. During cutting, because the guide wheel travels in a direction away from the limiting wheel, the entire steel plate cutting device tends to move away from the limiting wheel as it moves forward. This ensures the limiting wheel remains in contact with the side of the steel plate to be cut, making it more convenient to use, reducing labor intensity, increasing cutting efficiency and precision, and minimizing space occupation. Secondly, since the guide wheel is a steering wheel, a locking mechanism is provided between the guide wheel and the guide wheel frame, allowing adjustment of the guide wheel's direction of travel according to the roughness of the steel plate surface, further enhancing ease of use. Thirdly, because the limiting wheel positioning frame includes a limiting sleeve and a limiting frame body, with the limiting sleeve fitted onto the side support rod and equipped with a limiting locking mechanism, the position of the limiting wheel can be adjusted according to the width of the steel plate, broadening its application range. Fourthly, because the cutting gun frame includes a cutting sleeve and a cutting frame body, with the cutting sleeve fitted onto the transverse support rod and equipped with a cutting locking mechanism, the distance between the two cutting guns can be adjusted according to the width of the steel plate to be cut, further enhancing ease of use.

[0014] The structure and operating principle of the steel plate trimming device of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0015] As shown in Figures 1, 2, 3, and 4, the structural schematic diagram of the steel plate trimming device of this utility model is provided. The steel plate trimming device of this utility model includes a frame 1, a transverse support rod 2 on the frame 1, a cutting gun frame 3 on the transverse support rod 2, a cutting gun 4 on the cutting gun frame 3, a traveling wheel 6 connected to the traveling power mechanism 5 at the bottom of the frame 1, a side support rod 7 on the side of the frame 1 in front of the transverse support rod 2, a limit wheel positioning frame 8 on the side support rod 7, a limit wheel 9 on the limit wheel positioning frame 8, a guide wheel frame 10 in front of the frame 1, and a guide wheel 11 on the guide wheel frame 10. The traveling direction of the guide wheel 11 is biased away from the limit wheel 9.
[0016] Before cutting, an auxiliary plate with the same width and thickness as the steel plate is set in front of the steel plate 12. The length of the auxiliary plate is slightly greater than the distance from the cutting gun 4 to the front end of the frame 1, so that the auxiliary plate is aligned with the steel plate. The steel plate cutting device is placed above the steel plate, and the limiting wheel 9 is attached to the side of the steel plate. The traveling power mechanism 5 is turned on to drive the traveling wheel 6 to rotate. While the steel plate cutting device moves forward, the cutting gun cuts the edge of the steel plate. Because the direction of travel of the guide wheel is biased away from the limiting wheel, while moving forward, the entire steel plate cutting device tends to move away from the limiting wheel. In this way, the limiting wheel is always attached to the side of the steel plate to be cut, which makes it more convenient to use, reduces labor intensity, increases cutting efficiency, increases cutting accuracy, and occupies less space.
[0017] The guide wheel 11 is a steering wheel, and a locking mechanism 13 is provided between the guide wheel 11 and the guide wheel frame 10. The direction of travel of the guide wheel can be adjusted according to the roughness of the steel plate surface, making it more convenient to use.
[0018] The limiting wheel positioning frame 8 includes a limiting sleeve 81 and a limiting frame body 82. The limiting sleeve 81 is fitted onto the side support rod 7. A limiting locking mechanism 83 is provided on the limiting sleeve 81. The position of the limiting wheel is adjusted according to the width of the steel plate, thus expanding its application range.
[0019] The cutting gun holder 3 includes a cutting sleeve 31 and a cutting frame 32. The cutting sleeve 31 is fitted onto the horizontal support rod 2. A cutting locking mechanism 33 is provided on the cutting sleeve 31, which can adjust the distance between the two cutting guns according to the width of the steel plate to be cut, making it more convenient to use.
[0020] The scope of protection of this utility model is not limited to the above embodiments. Any structure that is the same as or similar to the structure of the steel plate edge cutting device of this utility model falls within the scope of protection of this utility model.
