Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, and specifically to a weld point diameter detection device for a steel cord butt welding machine. The device is mainly suitable for quality control of weld points of steel cord butt welding machines, and is generally used for the production of steel wire ropes (steel cords) with a diameter of 2 mm or less. Background Art

[0002] In the production process of high-strength steel cord, defects and broken wires are inevitable, which affect the product quality. Factories are accustomed to cutting and welding the defective parts to deal with substandard products. Therefore, steel cord butt welding machines are widely used in steel cord production enterprises.

[0003] When welding steel cord, a butt welding machine melts the two ends to be welded using an electric current and then connects them to complete the weld. However, because the steel cord is melted and extruded, irregular weld points are formed. A diameter that is too large prevents it from passing through the wire die during production at downstream companies; a diameter that is too small can affect the tensile strength at the weld point and cause wire breakage. To achieve full process control, the diameter of the steel cord weld point must be measured.

[0004] In the prior art, after the steel cord is welded, the operator only passes the weld point through a slot to detect the weld point diameter, which is not comprehensive and easily leads to missed detection. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a weld spot diameter detection device for a steel cord butt welding machine, which has signal output and can detect the diameter of the steel cord weld spot in multiple directions. The detection of the weld spot is more comprehensive and the possibility of missed detection is reduced. The steel cord weld spot is successively placed in the card slots of the diameter detection die heads of the vertical diameter detection die and the horizontal diameter detection die. Both diameter detection die have built-in inductive sensors. When a steel cord weld spot passes through the card slot, the corresponding inductive sensor sends a signal to the butt welding machine PLC, thereby achieving the purpose of controlling the entire process.

[0006] The purpose of this utility model is achieved in this way:

[0007] A device for detecting the diameter of weld points of a steel cord butt welding machine comprises a mounting frame and two diameter detection dies. The two diameter detection dies are arranged on the mounting frame front and back, with one diameter detection die placed vertically and the other placed horizontally. A card slot is provided on the top surface of the diameter detection die, the width of the card slot is adapted to the diameter of the weld point of the steel cord to be detected, and an inductive sensor is built into the diameter detection die, the inductive head of the inductive sensor reaches the bottom of the card slot.

[0008] Preferably, the diameter detection die is of split type, including a die base and a diameter detection die head. The die base is fixed on the mounting frame, and the diameter detection die head is fixed to the die base by screws. The card slot is set on the top surface of the diameter detection die head.

[0009] Preferably, the mounting frame is L-shaped, and the mounting frame is formed by bending a steel plate in one piece, including a straight section and an upright section. The straight section is used to install a vertical diameter detection mold, with the corresponding slot opening facing upward, to perform diameter detection on the steel cord weld in the front and rear directions; the upright section is used to install a horizontal diameter detection mold, with the corresponding slot opening facing forward, to perform diameter detection on the steel cord weld in the up and down directions.

[0010] Preferably, the mounting bracket is provided with a mounting hole corresponding to the mold base, and the mounting bracket is provided with a wire hole corresponding to the inductive sensor.

[0011] Preferably, the straight section of the mounting frame is further provided with a fixing hole, which is used to fix the device on the table of the steel cord butt welding machine.

[0012] Preferably, the top surface of the diameter detection die head is also marked with a diameter value of the adapted steel cord welding point.

[0013] The beneficial effects of the utility model are:

[0014] The steel cord welds are placed in the slots of the diameter detection die heads of the vertical and horizontal diameter detection dies in sequence. The slot opening of the vertical diameter detection die faces upwards, and the diameter of the steel cord welds is detected in the front-to-back direction. The slot opening of the horizontal diameter detection die faces forwards, and the diameter of the steel cord welds is detected in the top-to-bottom direction, thereby achieving multi-directional detection of the welds and avoiding missed detection.

[0015] Both diameter detection dies have built-in inductive sensors. When a steel cord weld passes through the slot, the corresponding inductive sensor sends a signal to the welding machine PLC, thereby achieving the purpose of controlling the entire process. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-3 The utility model relates to a weld point diameter detection device for a steel cord butt welding machine, comprising a mounting frame 1 and two diameter detection molds 2, the two diameter detection molds 2 being arranged on the mounting frame 1 front and back, and one diameter detection mold 2 being placed vertically, and the other diameter detection mold 2 being placed horizontally, a card slot 2.1 being provided on the top surface of the diameter detection mold 2, the notch of the card slot 2.1 being provided with a chamfer, the width of the card slot 2.1 being adapted to the diameter of the steel cord to be detected, the diameter detection mold 2 being provided with a built-in inductive sensor 3, the inductive head of the inductive sensor 3 reaching the bottom of the card slot 2.1, the diameter detection mold 2 being provided with a sensor accommodating cavity corresponding to the inductive sensor 3, the sensor accommodating cavity being communicated with the card slot 2.1.

[0021] The diameter detection die 2 is of split type, including a die base 2.2 and a diameter detection die head 2.3. The die base 2.2 is fixed on the mounting frame 1, and the diameter detection die head 2.3 is fixed to the die base 2.2 by screws, which is suitable for different types of steel cord diameter detection. The card slot 2.1 is set on the top surface of the diameter detection die head 2.3. The top surface of the diameter detection die head 2.3 is also marked with the diameter value of the adapted steel cord to prevent confusion of the diameter detection die head. When different diameter detection molds need to be replaced according to the different diameters of the steel cord, only the diameter detection die head needs to be replaced, which is quick, convenient, and cost-effective. The inductive sensor 3 is built into the die base 2.2, and the inductive head of the inductive sensor 3 enters the inner cavity of the diameter detection die head 2.3 after passing through the die base 2.2, so that the inductive sensor 3 can detect the steel cord welding point when it passes through and send a signal.

[0022] The mounting frame 1 is L-shaped and is formed by bending a steel plate in one piece. It includes a straight section and an upright section. The straight section is used to install a vertical diameter detection mold, with the corresponding slot opening facing upward, to perform diameter detection on the steel cord in the front and rear directions; the upright section is used to install a horizontal diameter detection mold, with the corresponding slot opening facing forward, to perform diameter detection on the steel cord in the up and down directions.

[0023] The mounting frame 1 is provided with a mounting hole 1.1 corresponding to the mold base 2.2, and the mounting frame 1 is provided with a wire hole 1.2 corresponding to the inductive sensor 3.

[0024] The straight section of the mounting frame 1 is further provided with fixing holes 1.3, which are used to fix the device on the table of the steel cord butt welding machine.

[0025] The die base 2.2 and the diameter detection die head 2.3 are both cylindrical, which are easy to process and can improve the accuracy and quality of parts to meet the needs of steel cord welding point diameter detection.

[0026] When the steel cord weld point passes through the slot, it is controlled by the slot width. If the diameter exceeds the slot width, it cannot pass through. If the diameter is within the tolerance, it can pass through. At the same time, the built-in induction sensor sends a signal, which is received by the PLC of the steel cord welding machine and controlled according to the program requirements, thereby achieving the purpose of controlling the diameter of the steel cord weld point.

[0027] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
