Description

Technical Field

[0001] This utility model relates to the field of shearing technology, and more specifically, to a double-end shearing device for rods. Background Technology

[0002] The double-end shearing device for bars cuts both ends, significantly reducing the processing time for a single bar and making it suitable for mass production environments. Secondly, it ensures shearing quality; simultaneous double-end shearing ensures symmetrical force on the bar, reducing deformation of the sheared surface, resulting in a smooth and flat cross-section, and improving the precision and quality of the sheared parts.

[0003] Among the existing published documents, patent publication number CN221065349U discloses a high-speed bar length stabilizing shearing device. This technology utilizes a spring that pushes the extrusion roller to compress the bar when it needs to be sheared by extrusion rollers and roller two, making it easier to handle bars of different thicknesses. However, this technology still has the following drawbacks.

[0004] During the shearing process, the two ends of the bar can be cut with a cutter. However, since there are various sizes of bars, they need to be cut one by one according to different sizes. It is difficult to cut the two ends of bars of various lengths simultaneously, resulting in low shearing efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a double-end shearing device for bars, comprising a sleeve plate, a long positioning plate fixed to the bottom of the inner wall of the sleeve plate, and a shearing module provided on one side of the long positioning plate, the shearing module comprising:

[0006] A middle positioning plate is located on one side of the long positioning plate, and a lower positioning plate is provided on one side of the middle positioning plate. Both the middle positioning plate and the lower positioning plate are fixedly connected to the sleeve plate.

[0007] A pressure plate is located above the middle positioning plate, and a first cutter is fixed at both ends of the pressure plate;

[0008] The second cutter is fixed at one end of the first cutter, and the other end of the first cutter is fixed with a third cutter. A pressure column is fixedly connected to the upper surface of the pressure plate, and an electric cylinder is installed at the top of the sleeve plate.

[0009] In a preferred embodiment, the length of the long positioning plate is greater than the length of the middle positioning plate, and the length of the middle positioning plate is greater than the length of the lower positioning plate.

[0010] In a preferred embodiment, the second cutter, the first cutter, and the third cutter are arranged in a stepped manner from left to right, and the lower surfaces of the second cutter and the first cutter are chamfered, as is the lower surface of the third cutter.

[0011] In a preferred embodiment, the electric cylinder is used to push the pressure column to move, and the outer wall of the output end of the electric cylinder is slidably connected to the sleeve plate.

[0012] In a preferred embodiment, the lower surface of the sleeve plate is provided with a plurality of mounting holes, which are arranged in a rectangular distribution.

[0013] In a preferred embodiment, a short plate is fixed between the two third cutters;

[0014] A sliding rod is installed on the upper surface of the short plate, a long plate is fixed between the two second cutters, and a sliding column is fixed on the upper surface of the long plate. Both the sliding rod and the sliding column are slidably connected to the sleeve plate.

[0015] In a preferred embodiment, the length of the long plate is greater than the length of the short plate, and the cross-sectional shape of both the long plate and the short plate is rectangular.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model uses a shearing module to place bars of different lengths inside the long positioning plate, the middle positioning plate, and the lower positioning plate respectively. The pressure plate moves down, so that the second cutter, the first cutter, and the third cutter simultaneously shear the bars of different lengths at both ends, greatly improving the shearing efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] like Figure 1 - Figure 4 The present invention relates to a bar double-end shearing device, which is equipped with a shearing module. The shearing module enables the second cutter 7, the first cutter 6, and the third cutter 8 to simultaneously shear bars of different lengths at both ends, thereby greatly improving the shearing efficiency. The specific structural configuration of the shearing module is as follows.

[0026] In this embodiment, as Figure 1 - Figure 2 As shown, a long positioning plate 2 is fixed to the bottom of the inner wall of the sleeve 1. A shearing module is provided on one side of the long positioning plate 2. The shearing module includes: a middle positioning plate 3, located on one side of the long positioning plate 2, and a lower positioning plate 4, both of which are fixedly connected to the sleeve 1; a pressure plate 5, located above the middle positioning plate 3, with a first cutter 6 fixed to both ends of the pressure plate 5; a second cutter 7, fixed to one end of the first cutter 6, and a third cutter 8 fixed to the other end of the first cutter 6; a pressure column 15 fixedly connected to the upper surface of the pressure plate 5; and an electric cylinder 9 installed at the top of the sleeve 1. The length of the long positioning plate 2 is greater than the length of the middle positioning plate 3, and the length of the middle positioning plate 3 is greater than the length of the lower positioning plate 4. The second cutter 7, the first cutter 6, and the third cutter 8 are arranged in a stepped manner from left to right. The lower surfaces of the second cutter 7 and the first cutter 6 are chamfered, and the lower surface of the third cutter 8 is also chamfered. The electric cylinder 9 is used to push the pressure column 15 to move, and the outer wall of the output end of the electric cylinder 9 is slidably connected to the sleeve plate 1.

[0027] In this embodiment, as Figure 3 As shown, the lower surface of the sleeve plate 1 has multiple mounting holes 10 arranged in a rectangular pattern to facilitate the insertion of bolts into the mounting holes 10, thereby fixing the sleeve plate 1 to the base and improving the stability of the sleeve plate 1.

[0028] In use, the double-end shearing device for bar stock is installed by inserting bolts into the mounting holes 10 to fix the sleeve plate 1 to the base. The sleeve plate 1 supports the electric cylinder 9. Then, bars of different lengths are placed in the long positioning plate 2, the middle positioning plate 3, and the lower positioning plate 4, respectively. Then, by activating the electric cylinder 9, the electric cylinder 9 pushes the pressure column 15 downward, the pressure column 15 drives the pressure plate 5 downward, the pressure plate 5 causes the first cutter 6 to move downward, the first cutter 6 drives the second cutter 7 downward, the second cutter 7 drives the third cutter 8 downward. In this way, the second cutter 7, the first cutter 6, and the third cutter 8 simultaneously shear the bars of different lengths at both ends.

[0029] In this embodiment, as Figure 4 As shown, a short plate 11 is fixed between the two third cutters 8;

[0030] A sliding rod 12 is mounted on the upper surface of the short plate 11, and a long plate 13 is fixed between the two second cutters 7. A sliding column 14 is fixed on the upper surface of the long plate 13, and both the sliding rod 12 and the sliding column 14 are slidably connected to the sleeve plate 1. The length of the long plate 13 is greater than the length of the short plate 11, and the cross-sectional shape of both the long plate 13 and the short plate 11 is rectangular.

[0031] When the double-end shearing device for bar stock is in use, the downward movement of the third cutter 8 will cause the short plate 11 to move downward. The short plate 11 causes the slide rod 12 to move downward. The slide rod 12 slides down along the inner wall of the sleeve plate 1. At the same time, the second cutter 7 causes the long plate 13 to move downward. The long plate 13 causes the slide column 14 to move downward. The slide column 14 slides down along the inner wall of the sleeve plate 1. This ensures that the two second cutters 7 and the two third cutters 8 move downward and shear synchronously and stably.

[0032] The contents not described in detail in the instruction manual (electric cylinder 9 is opened by a switch. This circuit is a series circuit. Series circuits are conventional and well-known circuits, so they will not be described in detail) are all existing technologies known to those skilled in the art. The model parameters of each electrical appliance are not specifically limited. Conventional equipment can be used. Electrical control components not mentioned in this technical solution are not shown in the figure because they are existing technologies, and will not be described here.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
