Description

Technical Field

[0001] The utility model relates to the technical field of silicon steel sheet stamping machines, in particular to a limiting device for a silicon steel sheet stamping machine. Background Art

[0002] Silicon steel sheet is a kind of silicon iron soft magnetic alloy with extremely low carbon content, generally with a silicon content of 0.5 - 4.5%. Adding silicon can improve the resistivity and maximum magnetic permeability of iron, reduce the coercive force, core loss (iron loss) and magnetic aging. It is mainly used to make the cores of various transformers, motors and generators.

[0003] Generally, after a large amount of silicon steel sheets are produced, they are long strip silicon steel sheets. Manufacturers need to cut the long strip silicon steel sheets into small pieces by a stamping machine for subsequent processing. During the stamping process, first, the feeding component conveys the long strip silicon steel sheet to the feeding end of the stamping machine, and then the stamping machine performs stamping on the long strip silicon steel sheet.

[0004] In the prior art, there is a utility model patent with the application number CN201821767798.2 and the patent name "A limiting device for a silicon steel sheet stamping machine", which has two limiting plates. The limiting plates are provided with limiting grooves for the silicon steel sheet to pass through and limit the silicon steel sheet. The openings of the two limiting plates are arranged oppositely, and the two limiting plates are respectively used to limit the two ends of the silicon steel sheet in the width direction, so as to prevent the long strip silicon steel sheet from horizontally shifting in position during the conveying process and ensure the stamping accuracy to a certain extent.

[0005] However, the heights of the upper and lower wall surfaces of the limiting groove of the limiting device in the above patent cannot be adjusted, resulting in that the limiting device cannot adapt to silicon steel sheets with a thickness greater than the heights of the upper and lower wall surfaces, and the limitation of the limiting device during use is relatively large. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is: to provide a limiting device for a silicon steel sheet stamping machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0007] The solution of the utility model to solve its technical problem is:

[0008] A limiting device for a silicon steel sheet stamping machine, comprising:

[0009] Two limiting components, the limiting component includes a main limiting frame, an adjusting limiting frame and a first adjusting structure. The adjusting limiting frame is slidably connected to the main limiting frame, and a limiting groove is formed between the adjusting limiting frame and the main limiting frame; the first adjusting structure drives the adjusting limiting frame to slide relative to the main limiting frame so as to change the height of the limiting groove.

[0010] Through the above technical solution, the staff can drive the adjustment limiting frame to move up and down relative to the main limiting frame through the first adjustment structure, so as to adjust the height of the limiting groove, so that the limiting device of the silicon steel sheet stamping machine can be adapted to silicon steel sheets of different thicknesses, and the adaptability of the limiting device of the silicon steel sheet stamping machine to silicon steel sheets of different thicknesses can be enhanced.

[0011] As a further improvement of the above technical solution, it further includes a spacing adjustment component, and the spacing adjustment component is used to adjust the spacing between the two limiting components.

[0012] As a further improvement of the above technical solution, the spacing adjustment component includes:

[0013] A horizontally placed spacing adjustment lead screw, with first threads and second threads with opposite helix directions respectively provided at both ends of the spacing adjustment lead screw; at least one end of the spacing adjustment lead screw is fixed with a lead screw drive structure;

[0016] As a further improvement of the above technical solution, the lead screw drive structure is a rotating handwheel.

[0019] As a further improvement of the above technical solution, the first adjustment structure is a screw structure, the first adjustment structure is in threaded connection with the main limiting frame, and the lower end of the first adjustment structure is rotatably connected to the adjustment limiting frame.

[0020] Through the above technical solution, when the first adjustment structure is driven by a worker to rotate, since the first adjustment structure is threadedly connected to the adjustment connection block of the main limit frame, the first adjustment structure will move upward or downward relative to the main limit frame. And since the lower end of the first adjustment structure is rotatably connected to the adjustment limit frame, when the first adjustment structure moves up and down relative to the main limit frame, it will drive the adjustment limit frame to move up and down relative to the main limit frame, thereby playing a role in adjusting the height of the limit slot.

If there is a description of first and second, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0031] Since the heights of the upper and lower wall surfaces of the limit groove of the limit device in the prior art cannot be adjusted, the limit device cannot be adapted to silicon steel sheets with a thickness greater than the heights of the upper and lower wall surfaces, resulting in a large limitation in the use of the limit device. In order to solve the technical problem that the limit device of the silicon steel sheet stamping machine in the prior art cannot be adapted to silicon steel sheets with different thicknesses, the present application has made certain improvements to the prior art to form the present solution.

[0032] Refer to Figure 1 , the limit device of the silicon steel sheet stamping machine includes two limit components and a spacing adjustment component 200.

[0033] The limit component includes a first adjustment structure 110, a limit adjustment frame 120 and a main limit frame 130.

[0034] The main limit frame 130 is provided with an adjustment connection block, and the adjustment connection block is arranged above the limit adjustment frame 120 (in other embodiments, the adjustment connection block can also be arranged below the limit adjustment frame 120, and those skilled in the art can select the installation position of the adjustment connection block according to actual needs). A limit slot 101 is formed between the limit adjustment frame 120 and the main limit frame 130.

[0035] The first adjustment structure 110 is arranged between the limit adjustment frame 120 and the main limit frame 130.

[0036] Specifically, in this embodiment, the first adjustment structure 110 is set as a screw structure. The first adjustment structure 110 is threadedly connected to the adjustment connection block of the main limit frame 130, and the lower end of the first adjustment structure 110 is rotatably connected to the adjustment limit frame.

[0037] When the staff drives the first adjustment structure 110 to rotate, since the adjustment connection block of the main limit frame 130 is threadedly connected to the first adjustment structure 110, the first adjustment structure 110 will move upward or downward relative to the main limit frame 130. And because the lower end of the first adjustment structure 110 is rotatably connected to the adjustment limit frame, when the first adjustment structure 110 moves up and down relative to the main limit frame 130, it will drive the adjustment limit frame to move up and down relative to the main limit frame 130, so as to adjust the height of the limit slot 101, so that the limit device of the silicon steel sheet stamping machine can be adapted to silicon steel sheets of different thicknesses, and the adaptability of the limit device of the silicon steel sheet stamping machine to silicon steel sheets of different thicknesses can be enhanced.

[0038] Specifically, in this embodiment, an adjustment driving structure is fixed to the upper end of the first adjustment structure 110, and the adjustment driving structure is set as a handwheel. The staff can directly drive the adjustment driving structure to move by hand, so as to drive the first adjustment structure 110 to rotate. In other embodiments, the adjustment driving structure can also be set as an electric rotating device, and those skilled in the art can select the specific structure of the adjustment driving structure according to actual needs.

[0039] In other embodiments, the first adjustment structure 110 can also be set as an electric linear driving device, and those skilled in the art can select the specific structure of the first adjustment structure 110 according to actual needs.

[0040] Specifically, in this embodiment, the main limit frame 130 is provided with a first scale line 131, and the adjustment limit frame is provided with a first pointer. The first scale line 131 cooperates with the first pointer to indicate the height of the limit slot 101. By setting the first scale line 131 and the first pointer, the staff can more intuitively know the height of the limit slot 101, thus avoiding the trouble of repeatedly measuring the height of the limit slot 101 during the adjustment process.

[0041] Specifically, in this embodiment, a first guiding structure 140 is provided between the adjusting limiting frame and the main limiting frame 130.

[0042] The first guiding structure 140 includes a first guiding sleeve and a first guiding column. The first guiding column extends in the up and down direction. The first guiding sleeve is sleeved on the first guiding column, and the first guiding column is slidably connected to the first guiding sleeve. The first guiding sleeve and the first guiding column are respectively connected to the adjusting limiting frame and the main limiting frame 130. Specifically, in this embodiment, the first guiding sleeve is fixedly connected to the adjusting limiting frame, and the first guiding column is fixedly connected to the main limiting frame 130. In other embodiments, the first guiding column can also be fixedly connected to the adjusting limiting frame, and the first guiding sleeve can be fixedly connected to the main limiting frame 130. Those skilled in the art can select the installation positions of the first guiding sleeve and the first guiding column according to actual needs.

[0043] By providing the first guiding structure 140, the adjusting limiting frame can be guided to avoid deviation during the sliding process of the adjusting limiting frame.

[0044] The spacing adjusting assembly 200 is used to adjust the spacing between the two limiting assemblies. Specifically, the spacing adjusting assembly 200 includes a spacing adjusting lead screw 210 and a spacing adjusting seat 220.

[0045] The spacing adjusting lead screw 210 extends in the horizontal direction. The two ends of the spacing adjusting lead screw 210 are rotatably connected to the frame of the silicon steel sheet stamping machine. The spacing adjusting lead screw 210 is provided with a second thread and a first thread. The second thread and the first thread are respectively arranged at the two ends of the spacing adjusting lead screw 210, and the helix directions of the second thread and the first thread are opposite.

[0046] Specifically, in this embodiment, screw drive structures 211 are fixedly arranged at both ends of the spacing adjusting lead screw 210. The screw drive structures 211 are set as rotating handwheels. Screw drive devices are provided at both ends of the spacing adjusting lead screw 210, enabling the staff to select one side of the spacing adjusting lead screw 210 to rotate the screw drive structure 211 to drive the rotation of the spacing adjusting lead screw 210, so that the staff can drive the spacing adjusting lead screw 210 more conveniently.

[0047] Specifically, in this embodiment, a rubber sleeve is sleeved on the screw drive structure 211. By sleeving a rubber sleeve on the outer periphery of the screw drive device, the friction between the staff's hand and the screw drive structure 211 can be increased, thereby effectively avoiding the staff's hand from slipping.

[0048] In other embodiments, the screw drive structure 211 can also be set as an electric rotating device. Those skilled in the art can select the specific structure of the screw drive structure 211 according to actual needs.

[0049] The number of the spacing adjustment seats 220 is set to two. The two spacing adjustment seats 220 are respectively arranged at both ends of the spacing adjustment lead screw 210. One of the spacing adjustment seats 220 is threadedly connected to the second thread, and the other spacing adjustment seat 220 is threadedly connected to the first thread. The two spacing adjustment seats 220 are respectively fixedly connected to the main limit frames 130 of the two limit assemblies.

[0050] By such setting, when the spacing adjustment lead screw 210 rotates, it will drive the two spacing adjustment seats 220 to approach or move away from each other, thereby driving the two limit assemblies to approach or move away from each other to adjust the distance between the two limit assemblies.

[0051] Specifically, in this embodiment, the spacing adjustment assembly further includes a second scale 230. The two limit assemblies are respectively set as a first limit assembly and a second limit assembly. The second scale 230 is fixedly installed on the main limit frame 130 of the first limit assembly. A second pointer is fixedly arranged on the main limit frame 130 of the second limit assembly. The second pointer cooperates with the second scale line to indicate the spacing between the two limit assemblies.

[0052] By setting the second scale 230 and the second pointer, the staff can more intuitively know the spacing between the two limit assemblies, thereby avoiding the trouble of repeatedly measuring the spacing between the two limit assemblies during the adjustment process.

[0053] Specifically, in this embodiment, a third guiding structure 300 is arranged between the lower end of the main limit frame 130 and the frame of the silicon steel sheet stamping machine.

[0054] The third guiding structure 300 includes a third guide rail 310 and a third sliding seat 320. The third guide rail 310 is fixedly installed on the frame of the silicon steel sheet stamping machine, and the third guide rail 310 extends horizontally. The third sliding seat 320 is fixedly connected to the main limit frame 130, and the third sliding seat 320 is slidably connected to the third guide rail 310. By setting the third guiding structure 300, the limit assembly can be guided to avoid deviation during the sliding process relative to the frame of the silicon steel sheet stamping machine.

[0055] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
