Description

Technical Field

[0001] The invention belongs to the technical field of point rails, and in particular to a bending knife for producing a point rail protective cover for a railway part. Background Art

[0002] The point rail is an important component in the switch. The train is guided to the main line or side line by the movement of the point rail. It is mainly used for turning the track. The tip of the point rail is easily broken after being bumped or hit, affecting the safe use of the point rail. Therefore, a protective cover is needed to protect the point rail.

[0003] The patent number is 202222540820.2, and a public specification published on March 31, 2023 discloses a switch point rail protective cover, including a switch point rail body and a switch point rail protective cover structure wrapped around the tip of the switch point rail body to protect the switch point rail body from collision and damage during transportation. In the utility model, the tip of the switch point rail body is completely wrapped by overlapping two memory sponges, which plays a role in soft wrapping protection of the tip of the switch point rail body. At the same time, the rubber inner shell outside the memory sponge provides support for the memory sponge through its own toughness, and the I-shaped buffer chamber inside the rubber inner shell allows the rubber inner shell to have the ability to shrink and buffer after deformation, and the metal outer shell outside the rubber inner shell provides anti-collision effect for the memory sponge, the rubber inner shell and the switch point rail body through its own hardness, thereby using the multiple wrapping protection of the tip of the switch point rail body by the switch point rail protective cover structure, so that the tip of the switch point rail body that is easy to break can be better protected during transportation or moving.

[0004] Because the existing bending equipment, when bending the plate, the equipment devices are all large equipment, the cost is relatively high, and the bending effect of the plate on the small bending equipment is not ideal, and when bending the U-shaped parts, it is easy to bend the already bent end again during the second bending, causing processing failure. Summary of the invention

[0005] The invention aims to provide a bending knife for producing railway part point rail protection covers with good bending effect.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a bending knife for producing a railway point rail protective cover, the protective cover is U-shaped, the bending knife is 7-shaped, the bending knife is divided into a long plate and a short plate connected to each other to form a 7-shape, and the outer end angle of the long plate away from the short plate is a right angle.

[0007] The protective cover is divided into a middle plate and side plates arranged on both sides of the middle plate. The side plates and the middle plate are attached to the two side walls of the right-angle end of the long plate, and the end of the long plate is attached to the middle plate.

[0008] The end of the side plate located on the middle plate away from one end of the long plate is located on the inner side of the bending knife.

[0009] The inner side of the bending knife is in an arc shape.

[0010] There is a gap between the inner surface of the bending knife and the end of the side plate.

[0011] A clamping plate is arranged on the outer side of the short plate, and the clamping plate and the short plate are perpendicular to each other.

[0012] The length of the outer wall of the long plate is the same as that of the side plate.

[0023] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0024] See also Figure 1 , a bending knife for producing a railway point rail protective cover, the protective cover 1 is U-shaped, the bending knife 2 is 7-shaped, the bending knife 2 is divided into a long plate 21 and a short plate 22 connected to each other to form a 7-shape, and the outer end angle of the long plate 21 away from the short plate 22 is a right angle; through the 7-shaped bending knife 2, after the bending knife 2 is placed on the plate to be bent, the plate is bent until it fits on the outer surface of the bending knife 2, and then the bending knife 2 is placed in the opposite direction, and the operation is repeated to complete the bending of the plate, the bending efficiency is high and the angle is in place, the overall structure is simple, and the operation is convenient, the right-angle end is used to realize the bending point as a right angle, so that the bent protective cover 1 has a fixed shape, and the 7-shaped bending knife 2 is used to protect the other end of the protective cover 1, so as to avoid the other end being squeezed by other structures during bending, causing problems with the bending angle.

[0025] The protective cover 1 is divided into a middle plate 12 and side plates 11 arranged on both sides of the middle plate 12. The side plates 11 and the middle plate 12 are attached to the two side walls of the right-angle end of the long plate 21, and the end of the long plate 21 is attached to the middle plate 12. The right-angle end of the long plate 21 is used to achieve the verticality between the long plate 21 and the short plate 22, with high bending efficiency and precise angle.

[0026] The end of the side plate 11 on the middle plate 12 away from the long plate 21 is located on the inner side of the bending knife 2; the bending knife 2 is used to protect the bent end to prevent the bent end from being squeezed by other structures, causing an abnormal bending angle.

[0027] The inner side of the bending knife 2 is in an arc shape; while facilitating processing, it can improve the overall structural strength and reduce the occurrence of breakage.

[0028] There is a gap between the inner surface of the bending knife 2 and the end of the side plate 11, which prevents the bending knife 2 from directly squeezing the end, thereby ensuring a precise bending angle.

[0029] A clamping plate 3 is provided on the outer side of the short plate 22, and the clamping plate 3 and the short plate 22 are perpendicular to each other; the clamping plate 3 is clamped and fixed by a clamping tool to prevent the entire device from shaking.

[0030] The outer wall length of the long plate 21 is the same as that of the side plate 11; to avoid bending, the end of the side plate 11 does not have enough pressure surface due to the excessive length of the side plate 11, causing the end of the side plate 11 to bend.

[0031] The long plate 21 is located on the inner side of the protective cover 1 ; the long plate 21 and the middle plate 12 can be attached to two adjacent surfaces of the long plate 21 for easy bending.

[0032] A method for bending a protective cover 1 is implemented by using a bending knife for producing a railway part pointed rail protective cover, and the steps are as follows:

[0033] S1: Mark the bending point on the plate to be bent, place the end of the long plate 21 of the bending knife 2 on a marked line of the plate, and fix the clamping plate 3 with a tool;

[0034] S2: bending one end of the plate located outside the long plate 21 toward the long plate 21 until it is in contact with the outer surface of the long plate 21;

[0035] S3: After removing the bending knife 2, place it on another marking line of the plate in the opposite direction, and fix the clamping plate 3 with a tool, so that one end of the bent plate is located on the inner side of the bending knife 2;

[0036] S4: bending one end of the plate located outside the long plate 21 toward the long plate 21 until it is in contact with the outer surface of the long plate 21 to complete the bending.

[0037] The technical effect of the present invention is: through the 7-shaped bending knife 2, after the bending knife 2 is placed on the plate to be bent, the plate is bent until it fits on the outer surface of the bending knife 2, and then the bending knife 2 is placed in the opposite direction. The operation is repeated to complete the bending of the plate. The bending efficiency is high and the angle is in place. The overall structure is simple and the operation is convenient.

[0038] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
