Description

Technical Field

[0001] The utility model relates to the technical field of scribing tooling, in particular to a scribing device for batch production of thin plate shearing parts. Background Art

[0002] In the manufacturing process of the stator casing of a turbogenerator, the steel plate welding structure is an indispensable part. For plates with a thickness of more than 3 mm, gas cutting is usually used for blanking. For thin plates with a thickness of less than 3 mm, since they are mostly used for fine parts such as small supports and gaskets, a shearing machine is more inclined to be used for blanking. To facilitate batch blanking, the complex surfaces are designed and joined with common angles.

[0003] In the early shearing preparation stage of thin plates, the angles to be sheared need to be drawn. Currently, the traditional method of drawing the shearing angle relies on the combined use of a protractor and a ruler. First, the operator needs to use a protractor to accurately measure and set the required angle, and then use the ruler as a guide to draw the corresponding shearing line on the thin plate.

[0004] Although the traditional method can meet the requirements of thin plate shearing to a certain extent, the inventor found that: the combined use of a protractor and a ruler increases the complexity of the operation, so the scribing efficiency is low and it is difficult to meet the fast-paced requirements of modern industrial production. Summary of the Utility Model

[0005] By providing a scribing tooling for batch production of thin plate shearing parts in the embodiments of the present application, the technical problems of cumbersome scribing process and low efficiency in the prior art are solved.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme. A scribing device for batch production of thin plate shearing parts includes a laterally extending cylindrical sliding rod and a scribing plate cooperating with the cylindrical sliding rod. The scribing plate is strip-shaped and at least two are provided. The included angle formed by the extending direction of each scribing plate and the extending direction of the cylindrical sliding rod is different; sleeves are provided at one end of each scribing plate, and the sleeves are nested on the outer periphery of the cylindrical sliding rod.

[0007] Since the scribing plate cooperates with the cylindrical sliding rod through the sleeves at one end, and multiple sleeves are provided, during the scribing process, the edge of the thin plate can be abutted against one side of the device, the corresponding scribing plate can be selected according to the scribing angle, rotated above the thin plate, and then scribing is carried out, without the combined use of a protractor and a ruler, improving the scribing efficiency.

[0008] Further, it further includes a bottom cross bar which is located on one side of the cylindrical slide bar and has the same extending direction as that of the cylindrical slide bar; thus, the edge of the thin plate can abut against one of its side surfaces, which helps to fix the position of the thin plate during the scribing process, prevent the thin plate from moving or shifting during scribing, and further improve the accuracy and consistency of scribing.

[0009] Further, the two ends of the bottom cross bar and the two ends of the cylindrical slide bar are fixedly connected by a connecting plate.

[0010] Further, the connecting plate is fixedly welded to the bottom cross bar, and the connecting plate and the end of the cylindrical slide bar are fixed by bolts; thus, the assembly and disassembly between the connecting plate and the cylindrical slide bar are realized, and further the addition or replacement of the scribing plate can be realized.

[0011] Further, the included angle formed between the extending direction of the scribing plate and one extending direction of the cylindrical slide bar increases or decreases in sequence; thus, the arrangement chaos of the scribing plates can be avoided, and when using a scribing plate at a certain angle, it can be found more quickly.

[0012] Further, each scribing plate is marked with an angle value.

[0013] It can be seen from the above technical solutions that the utility model has at least the following technical effects or advantages:

[0014] 1. Since the scribing plate is matched with the cylindrical slide bar through a sleeve at one end and there are multiple sleeves, during the scribing process, the edge of the thin plate can be abutted against one side of the device, select the corresponding scribing plate according to the scribing angle, rotate it above the thin plate, and then carry out scribing, without the need to use a protractor and a ruler in cooperation, thus improving the scribing efficiency;

[0015] 2. Since a bottom cross bar is arranged on one side of the cylindrical slide bar, the edge of the thin plate can abut against one of its side surfaces, which helps to fix the position of the thin plate during the scribing process, prevent the thin plate from moving or shifting during scribing, and further improve the accuracy and consistency of scribing;

[0016] 3. Since the connecting plate and the end of the cylindrical slide bar are fixed by bolts, the assembly and disassembly between the connecting plate and the cylindrical slide bar are realized, and further the addition or replacement of the scribing plate can be realized.

[0021] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in this patent, other embodiments obtained by those of ordinary skill in the art without making creative efforts all fall within the protection scope of this patent.

[0022] The present utility model discloses a scribing device for batch production of thin plate shearing parts, which includes a horizontally extending cylindrical slide bar 1 and a plurality of scribing plates 2 cooperating with the cylindrical slide bar 1. One end of the scribing plate 2 is nested on the outer periphery of the cylindrical slide bar 1 and can rotate or slide relative to the cylindrical slide bar 1. In one example, this device can be abutted against the edge of the thin plate, and the appropriate scribing plate 2 can be selected according to the shearing angle, so that the scribing plate 2 is rotated above the thin plate, and then scribing is carried out.

[0023] A sleeve 3 is fixed to one end of the scribing plate 2, and the sleeve 3 is nested on the outer periphery of the cylindrical slide bar 1. Thus, the scribing plate 2 can slide or rotate relative to the cylindrical slide bar 1. Furthermore, more scribing plates 2 can be installed outside the cylindrical sleeve 3, so that this device has more scribing angles. It should be understood that in order to improve the scribing accuracy, the clearance between the sleeve 3 and the cylindrical slide bar 1 should be small. In other embodiments, the axial length of the sleeve 3 can also be increased.

[0024] In this embodiment, the scribing device for batch production of thin plate shearing parts further includes a bottom cross bar 4. The bottom cross bar 4 is located at the bottom of the cylindrical slide bar 1, and its extending direction is consistent with that of the cylindrical slide bar 1. Specifically in this embodiment, as Figure 2 shown, both ends of the bottom cross bar 4 are fixedly connected to both ends of the cylindrical slide bar 1 through a connecting plate 5. Among them, the cross section of the bottom cross bar 4 is rectangular. When scribing is carried out with the aid of this device, one bottom surface of the bottom cross bar 4 contacts the ground or the working surface of the workbench, and the edge of the thin plate can abut against one side surface of the bottom cross bar 4 to ensure that the thin plate is more stable during the scribing process.

[0025] In addition, a groove is provided on one side of the scribing plate 2 close to the sleeve 3. During the use of the device, rotating the scribing plate 2 can make the groove engage with the outside of the bottom cross bar 4, thereby keeping the scribing plate 2 more stable. At the same time, the setting of the groove can make the lower edge of the scribing plate 2 fit the plate surface of the thin plate, so as to make the scribing more accurate.

[0026] As Figure 2 shown in the partial enlarged view in, in this embodiment, the connecting plate 5 and the bottom cross bar 4 are fixed by welding, and the connecting plate 5 and the end of the cylindrical sliding rod 1 are fixed by bolts 6. Specifically, in this embodiment, the cylindrical sliding rod 1 is a solid tubular structure, and threaded holes are provided at both ends of the cylindrical sliding rod 1 along the axial direction. Correspondingly, through holes are provided on the connecting plate 5. Thus, when the bolt 6 passes through the through hole on the connecting plate 5, it can cooperate with the threaded hole at the end of the cylindrical sliding rod 1, thereby realizing the connection and fixation between the cylindrical sliding rod 1 and the connecting plate 5. When the scribing plate 2 needs to be added or replaced, the two bolts 6 can be unscrewed and the cylindrical sliding rod 1 can be removed, so that the device has stronger applicability.

[0027] In this embodiment, please refer to Figure 1 , the included angle formed between the extending direction of the scribing plate 2 and one extending direction of the cylindrical sliding rod 1 increases or decreases in sequence, thereby avoiding the chaotic arrangement of the scribing plates 2. When using the scribing plate 2 at a certain angle, it can be found more quickly. In addition, each scribing plate 2 is marked with an angle value, which can make the use of the device more convenient.

[0028] When scribing the thin plate with the aid of this device, first make all the scribing plates 2 located on the side of the cylindrical sliding rod 1 away from the cylindrical sliding rod 1, make the bottom of the bottom cross bar 4 contact the ground or the surface of the workbench, make the edge of the thin plate abut against the edge of the bottom cross bar 4, then select a suitable scribing plate 2 according to the required scribing angle, rotate it above the thin plate, and then scribe. During this process, there is no need to use a single workpiece template for scribing, which improves the work efficiency.
