Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to a device for detecting the diameter of steel cord welding points. Background Art

[0002] During the production process of steel cord, welding is required due to reasons such as broken wire. The cord after welding will change due to the relationship between the weld points. Generally, the weld point diameter can be slightly larger than the original cord diameter within the allowable range, and normally does not exceed 110% of the cord diameter. Therefore, a special detection device is needed to control the detection of the weld point diameter. Generally, the weld point detection device is detected by a detection block with a fixed diameter slot. During the detection, the weld point needs to be placed in the diameter detection slot and rotated back and forth to ensure that each angle meets the weld point diameter requirements.

[0003] However, the above detection process is cumbersome, and when rotating, if the weld point is stuck in the groove, the weld point does not rotate when the steel cord rotates. Therefore, this detection often misses and does not meet the use requirements. Utility Model Content

[0012] Preferably, the first direction is a vertical direction, and the second direction is a horizontal direction.

[0013] Preferably, the third channel is located in the extension direction of the length of the second channel.

[0014] Preferably, the extension direction of the third channel length and the extension direction of the second channel length form a predetermined angle.

[0015] Preferably, the block includes a base portion, a middle portion and an extension portion, wherein the upper portion of the base portion extends toward both sides to form the middle portion, and the middle portion narrows inwardly and extends upward to form the extension portion.

[0026] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0027] Combine Figure 1 and Figure 3 As shown, the first aspect of the present invention provides a device for detecting the diameter of a steel cord weld, comprising a block having a first channel 102, a second channel 103, and a third channel 104 interconnected. When inspecting the weld of a steel cord, a weld M of a steel cord G is passed through the first channel 102, the second channel 103, and the third channel 104. If the diameter of the weld of the steel cord is too large, it cannot pass through the channels of a predetermined height, indicating that the weld is unqualified.

[0028] Among them, the first channel 102 is constructed to have a consistent height at each position along the length of the channel, the second channel 103 is constructed to have a consistent height at each position along the length of the channel, and the third channel 104 is constructed to have a consistent height at each position along the length of the channel.

[0029] It should be understood that the height of the channel refers to the distance between the wall on one side of the channel and the wall on the opposite side, the length of the channel refers to the extension direction of the channel, and the width of the channel is the same as the width of the block.

[0030] Furthermore, the heights of the first channel 102, the second channel 103, and the third channel 104 are the same and equal to a preset value. For example, if the diameter of the steel cord is L, the maximum outer diameter of the weld point M should be less than or equal to (1+10%) L. The height of the first channel 102 is L1, and the heights of the second channel 103 and the third channel 104 are L2, where L1 = L2 = (1+10%) L. In this way, the inspection standards for the first channel 102, the second channel 103, and the third channel 104 are the same, and only weld points M of steel cords within the standard diameter, that is, less than or equal to (1+10%) L, are allowed to pass.

[0031] Furthermore, the extending direction of the first channel 102 and the extending direction of the second channel 103 have different angles, and the extending direction of the first channel 102 and the extending direction of the third channel 104 have different angles.

[0032] In this way, by setting multiple channels at different angles, the outer diameter of the weld can be inspected from multiple angles.

[0033] Specifically, the widths of the first channel 102 , the second channel 103 and the third channel 104 are greater than the lengths of the steel cord welding points.

[0034] For example, the length of the welding spot M is usually less than 10 mm. Optionally, the width of the block is set to 10 mm, so that the welding spot M can completely enter the channel.

[0035] In an optional embodiment, a diameter-expanding channel 101 is provided at the entrance of the first channel 102 , and the height of the diameter-expanding channel 101 is greater than the height of the first channel 102 .

[0036] In this way, when the user holds the steel cord and places it into the first channel 102, it is relatively convenient and the steel cord can be placed without the need for complete alignment.

[0037] Furthermore, the height of the intersection of the first channel 102 , the second channel 103 and the third channel 104 is greater than the height of the first channel 102 , the second channel 103 or the third channel 104 .

[0038] In this way, the steel cord can be slightly rotated at the intersection of the first channel 102 , the second channel 103 and the third channel 104 , thereby changing the angle of the steel cord.

[0039] In an optional embodiment, the first channel 102 is arranged along a first direction, the second channel 103 and the third channel 104 are arranged along a second direction, and the first direction is perpendicular to the second direction.

[0040] Preferably, the first direction is the vertical direction, and the second direction is the horizontal direction. Figure 1 As shown, the third channel 104 is located in the extension direction of the length of the second channel 103.

[0041] like Figure 1 and Figure 2 As shown, the steel cord is passed through the first channel 102. Department ( Figure 3 Enter the first channel Department ( Figure 4 As shown), if the steel cord can completely pass through the first channel 102 and reach the intersection of the three channels, the horizontal diameter of the welding point M of the steel cord meets the requirements, and then the steel cord enters the second channel 103. Department ( Figure 5 As shown), if it can completely enter the second channel 103, the diameter of the welding point M in the vertical direction meets the requirements. After that, the steel cord exits the second channel 103 and rotates 45 degrees at the intersection of the three channels (at this time, the rotation angle of 45 degrees is the actual rotation angle of the welding point because the welding point will not be blocked) to enter the third channel 104. Department ( Figure 6 As shown in the figure), if the steel cord can completely pass through the third channel 104, the diameter of the weld point M of the steel cord at an oblique 45° direction meets the requirement. It can be seen that by controlling the steel cord to pass through the first channel 102, the second channel 103 and the third channel 104 in sequence in this way, the outer diameter of the steel cord weld point can be detected from multiple angles, and the detection result is more accurate.

[0042] In other embodiments, the direction in which the third channel 104 extends forms a predetermined angle with the direction in which the second channel 103 extends. For example, the third channel 104 is not in the direction in which the second channel 103 extends, but is tilted 45° relative to the second channel 103. This allows the outer diameter of the steel cord to be detected at multiple angles without rotating the steel cord when the steel cord is controlled to pass from the second channel 103 to the third channel 104.

[0043] In the above embodiment, the block includes a base portion 1 , a middle portion 2 and an extension portion 3 . The upper portion of the base portion 1 extends toward both sides to form the middle portion 2 , and the middle portion narrows inward and extends upward to form the extension portion 3 .

[0044] The first channel 102 extends downward from the top of the extension portion 3 to the middle portion 2 , and the second channel 103 and the third channel 104 extend from the lower end of the first channel 102 to the left and right sides of the middle portion 2 .

[0045] Specifically, the block is a stainless steel block, and the first channel 102, the second channel 103 and the third channel 104 are formed by internal processing. The steel cord weld point detection device formed in this way is reliable and durable.

[0046] In combination with the above embodiments, the weld point diameter measuring device proposed by the present invention is provided with a first channel, a second channel and a third channel on the block, and the extension directions of the first channel, the second channel and the third channel are different. Therefore, when the user holds the steel cord and makes the weld point pass through the first channel, the second channel and the third channel in sequence, the outer diameter of the weld point can be detected at multiple angles rather than a single angle, so that the detection result is more accurate.

[0047] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
