High strength steel cord straightness detection device that hangs down
Technical Field
The invention relates to a high-strength steel cord perpendicularity detection device, and belongs to the technical field of steel cord testing.
Background
With the continuous improvement of the automation degree of tire factories, related equipment has higher quality control requirements on used steel cord products, particularly, poor straightness of the steel cord can be caused when the number of the used steel cords of the produced film is small, the poor straightness of the steel cord has great influence on the straightness of the film, and adverse effects are brought to the product quality and the automatic production of the produced film.
The flatness detection index of the existing steel cord is flatness, and the detection steps are as follows: and pulling out the sample to be tested for 6m from the I-shaped wheel, allowing the sample to rotate freely, releasing the residual torsion, placing the sample between two horizontal lines with the interval width of 75mm, applying no tension to the sample, and observing whether the sample is in contact with any one of the two parallel lines. When the method is used for detecting the qualified steel cord, the rubber sheets have poor straightness when being used for producing rubber sheets with less steel cord number in a tire factory.
Therefore, there is a need for a detection apparatus and a detection method with higher detection capability for the straightness of steel cords, which are used to improve the detection and monitoring requirements for the straightness of steel cords, thereby reducing the influence on the straightness of rubber sheets due to poor straightness of cords, and improving the product quality and production efficiency of tire factories.

In order to achieve the above purpose, the invention provides a high-strength steel cord verticality detection device, which comprises a detection panel, a limiting groove, a scale bar and a plumb line, wherein the limiting groove is positioned above the scale bar, the limiting groove is positioned at the front side of the detection panel or the limiting groove is positioned above the detection panel, the scale bar is transversely and fixedly arranged on the surface of the detection panel, the plumb line is fixed at the rear side of the detection panel,
preferentially, including unable adjustment base and adjusting screw, the fixing base card is connected and is detected the panel, unable adjustment base bottom be provided with a plurality of through a plurality of nut is adjustable and be used for adjusting the straightness's that hangs down horizontal adjusting screw of detecting the panel, the horizontal adjusting screw threaded connection at least one nut that is located the unable adjustment base top, the horizontal adjusting screw threaded connection at least one nut that is located the unable adjustment base below, unable adjustment base is plane panel.
Preferentially, unable adjustment base includes diaphragm and a plurality of block board, the vertical fixed connection diaphragm of a plurality of block board, all sets up the draw-in groove that the cooperation detected the panel on a plurality of block board, and block board and diaphragm are plane panel.
Preferentially, be fixed with the strong magnet on detecting the vertical central line of panel, the strong magnet adsorbs fixedly to the test sample of different diameters, detects the panel and is plane panel.
Preferably, the detection panel is an organic glass panel or a nonmagnetic panel.
Preferably, the total length of the scale bar is one meter.
Preferably, the vertical center line of the scale bar coincides with the vertical center line of the detection panel, the scale bar is marked with a scale value, the number of the center of the scale bar is zero, and the scale value is increased from the middle to two sides.
Preferentially, the limiting groove is V-shaped, the bottom of the limiting groove is flush with the upper surface of the detection panel, and the zero value of the limiting groove and the center of the scale bar is on the same plumb line.
Preferably, the fixing base is fixedly provided with a horizontal point for judging whether the detection panel is vertical or not.
The invention achieves the following beneficial effects:
according to the invention, the verticality detection is carried out on the sampling of the test sample, so that the detection requirement and the monitoring requirement on the straightness of the steel cord are improved, the influence on the straightness of the rubber sheet due to poor straightness of the cord is reduced, and the product quality and the production efficiency of a tire factory are improved; the strong magnet is fixed on the vertical central line of the detection panel to adsorb and fix the test samples with different diameters by the strong magnet, so that the test samples are attached to the detection panel, and the test is more accurate.

Detailed Description
The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
It should be noted that, if there is a directional indication (such as up, down, left, right, front, and back) in the embodiment of the present invention, it is only used to explain the relative position relationship between the components, the motion situation, and the like in a certain posture, and if the certain posture is changed, the directional indication is changed accordingly.
The device provides a device for detecting the verticality of a steel cord, which mainly comprises a detection panel 1, a scale bar 3, a limiting groove 2, a plumb line 4, a fixed base 5 and an adjusting screw 6,
the detection panel 1 is an organic glass panel or other nonmagnetic material panel, and the surface is smooth and flat;
the scale bar 3 is positioned on the surface of the detection panel 1, the total length of the scale bar 3 is 1m, the center of the scale bar 3 is 0 and is positioned at the vertical position of the center of the detection panel 1, and scale marks in the horizontal direction at the bottom of the scale bar are marked with scale values; the scale strips 3 can be distinguished by different colors, for example, the qualified range is green, the range needing to be adjusted is yellow, and the unqualified range is red, so that an operator can conveniently and directly judge, identify and make corresponding adjustment.
The limiting groove 2 is a V-shaped groove and is assembled above the scale strip 3, the surface of the detection panel 1 at the bottom of the limiting groove 2 is level and is positioned on the same straight line with the central 0 value of the scale strip 3, and strong magnetism is embedded on the panel corresponding to the position of the limiting groove 2, so that test samples 7 with different diameters can be adsorbed and fixed;
