Description

Technical Field

[0001] The utility model relates to the technical field of aperture measurement, in particular to a wire drawing die aperture measurement system. Background Art

[0002] A wire drawing die is a mold used to draw metal wire. It has a central hole of a specific shape, such as round, square, octagonal, or other specialized shapes. As the metal is drawn through the hole, its size decreases and its shape may even change. Wire drawing dies are widely used in the production of various metal wires, including high-precision wires required for electronics, radar, television, instrumentation, and aerospace applications.

[0003] The Chinese authorized announcement number is CN 215893479 U, which describes a device for measuring the center aperture of a wire drawing die. By providing a measuring needle, a measuring head, and a reset spring, the device only needs to enter the center aperture of the wire drawing die and appropriately adjust the position of the measuring device. The center aperture of the wire drawing die can then be measured based on the readings of the two measuring needles. The measuring head is very convenient for entering the center aperture of the wire drawing die, and the surface of the measuring head is spherical, which can fit inside the center aperture of the wire drawing die and measure the aperture data more accurately. By providing a screw and a limit rod, when measuring the center aperture of a wire drawing die with a very large difference in size, the two measuring heads can be adjusted to an equal distance apart so that the two measuring heads just slightly exceed the size of the center aperture of the wire drawing die. This allows the measuring device to measure a larger range of the center aperture of the wire drawing die and has better applicability.

[0004] However, this patent still has certain shortcomings when used. When measuring the aperture of the drawing die, the drawing die needs to be positioned, but the existing aperture measuring device generally measures directly on the die. However, some molds are small in size, and there will be an offset when measuring using the measuring device, which will cause the position of the mold to deviate during measurement, thereby affecting the accuracy and reliability of the measurement results. In addition, the existing aperture measuring device is generally manual measurement. Since the accuracy of manual measurement is limited by the skills and experience of the measurement personnel, it may cause errors in the measurement results, thereby reducing the accuracy of the aperture measurement.

[0016] 1. In the utility model, a measuring assembly is formed by arranging a measuring rod, an infrared ranging probe, a display screen, a rotating slot, a measuring block and a pressure spring, thereby realizing the aperture measurement of the mold body.

At this time, the slide rod is reset under the action of the first spring rebound, and the limit block moves and abuts the top of the mold body. After clamping is completed, the driving motor is controlled to move the moving clamping block to the middle, and the limit block on this side is pulled upward until the mold body and the clamping block are fitted and released, thereby realizing the positioning of the mold body, making the mold body in a fixed position, reducing the repeated measurement and adjustment time caused by inaccurate measurement, thereby improving production efficiency, and at the same time, avoiding measurement errors caused by position changes.
