Description

Technical Field

[0001] The invention relates to the technical field of bolt knurling and thread rolling equipment, in particular to a flat cup anti-skid bolt rod knurling and thread rolling device and a use method thereof. Background Art

[0002] Bolts are mechanical parts, cylindrical threaded fasteners equipped with nuts. Their main function is to connect and fix parts to ensure the safe operation of machines and equipment. In bolt production, the main methods of thread forming include thread rolling, thread rolling, and tapping. Thread rolling and thread rolling are methods of obtaining threads by extruding materials and are used to manufacture external threads.

[0003] When rolling and knurling the flat cup bolts, after the flat cup bolts are transported to the thread rolling plate via the conveyor belt, since the flat cup bolts have a taper, the thread rolling will be crooked if the machine is not adjusted properly.

The bolts often collide and rub against the knurling device during knurling, which easily generates debris. When the device is cleaning metal debris, the machine needs to be stopped and the thread rolling plate cannot continue to roll, which wastes time and affects work efficiency.

[0016] Furthermore, a method for using a flat cup anti-slip bolt rod knurling thread rolling device comprises the following steps:

[0017] S1: First, place the bolts to be threaded with their big heads facing upwards one by one into the placement slot, and continue to place more after it is full, so that the bolt blank moves to the thread rolling working area. When the bolt is at the bottom of the limit plate, the spring is pressed down to allow the limit plate to limit and squeeze the bolt, and the cylinder is started. The cylinder pushes the extrusion plate to move, and the extrusion plate squeezes the bolt between the fixed die rolling plate and the movable die rolling plate. After squeezing in, the cylinder drives the extrusion plate to reset, and the extrusion plate drives the tooth plate 1 to move. The tooth plate 1 slides in the concave slide frame through the convex slide plate 1, and the tooth plate 1 engages with the fixed gear part, which can make the fixed gear part rotate, so that the fixed gear part can drive the tooth plate 2 to move toward the bolt, so that the tooth plate 2 drives the limiting clamping plate to limit the unprocessed bolt.

[0018] S2: When the bolt enters the processing area, the servo motor drives the rotating rod to rotate, and the rotating rod drives the belt to rotate through the pulley. The belt drives the rotating shaft and the rotating disk to rotate, so that the rotating disk pulls the push-pull rod through the connecting rod to move back and forth. The push-pull rod pulls the movable die rolling plate through the push-pull hinge to move. The movable die rolling plate slides on the concave guide rail through the convex slider, thereby rolling the bolts entering the processing area;

[0019] S3: When the movable die plate moves, the movable die plate drives the L-shaped connecting frame and the reciprocating tooth plate to reciprocate. The reciprocating tooth plate meshes with the gear, which can rotate the gear. The gear drives the rotating rod to rotate. When the oil inlet hole on the rotating rod is connected with the oil inlet hole, the lubricating liquid in the lubricating oil storage barrel enters the rotating rod and is discharged from the oil outlet hole. The lubricating oil is absorbed by the smear roller, which can be used to smear the movable die plate.

[0020] S4: When the rotating disk drives the connecting rod to rotate, the movable die plate contacts the L-shaped push plate, which pushes the movable plate into the cleaning box to squeeze. The gas in the cleaning box is transferred to the injection pipe through squeezing. The squeezed gas is discharged through the injection pipe. The discharged gas cleans the movable die plate and cools it down.

[0021] S5: When the rotating rod drives the rotating plate to slide in the slide groove, the reciprocating plate moves with the hinge as the axis, the reciprocating plate drives the sliding rod to move, the sliding rod drives the reciprocating block and the spray pipe to move, and the spray pipe slides on the limit groove, so that the spray pipe moves back and forth in a straight line. The water pump sucks the liquid in the oil storage tank through the oil suction pipe and discharges it into the spray pipe through the oil outlet pipe, so that the spray pipe can spray the liquid back and forth in the processing area.

[0022] The present invention has the following beneficial effects:

[0023] The present invention relates to a flat cup anti-skid bolt rod knurling and a method for using the same, when the bolt needs to be knurled and threaded, first put the bolt to be threaded into the placement slot with the big head facing upwards, and continue to put it in after it is full, so that the bolt blank moves to the thread rolling working area, and when the bolt is at the bottom of the limit plate, the spring is pressed down to make the limit plate limit and squeeze the bolt, so that the bolt is squeezed into the thread rolling working area, ensuring the verticality of the flat cup bolt, starting the cylinder, and the cylinder pushes the extrusion plate to move, and the extrusion plate squeezes the bolt into the fixed die rolling plate and the movable die rolling plate. After squeezing in, the cylinder drives the extrusion plate to reset, and the extrusion plate drives the tooth plate to move, and the tooth plate slides in the concave slide rack through the convex slide plate, and the tooth plate is meshed with the fixed gear part, which can make the fixed gear part rotate, so that the fixed gear part can drive the tooth plate two to move toward the bolt, so that the tooth plate two drives the limiting clamping plate to limit the unprocessed bolt, thereby preventing multiple bolts from entering the processing area and affecting the processing effect.

[0024] 2. A flat cup anti-slip bolt rod knurling thread rolling device and its use method. When the bolt enters the processing area, the servo motor drives the rotating rod to rotate, and the rotating rod drives the belt to rotate through the pulley. The belt drives the rotating shaft and the rotating disk to rotate, so that the rotating disk pulls the push-pull rod to move back and forth through the connecting rod. The push-pull rod pulls the movable die rolling plate to move through the push-pull hinge. The movable die rolling plate slides on the concave guide rail through the convex slider, thereby rolling the bolts entering the processing area, ensuring orderly and high-precision thread rolling, and avoiding slanted and messy threads.

[0025] 3. A flat cup anti-slip bolt rod knurling thread roller and a method of using the same. When the movable die tooth plate moves, the movable die tooth plate drives the L-shaped connecting frame and the reciprocating tooth plate to reciprocate. The reciprocating tooth plate is engaged with the gear, which can cause the gear to rotate. The gear drives the rotating rod to rotate. When the oil inlet hole on the rotating rod is connected with the oil inlet hole, the lubricating liquid in the lubricating oil storage barrel enters the rotating rod and is discharged from the oil outlet hole. The lubricating oil is absorbed by the smearing roller, which can be used to smear the movable die tooth plate, thereby reducing the wear of the movable die tooth plate and extending its service life. It also prevents excessive lubricating oil from being smeared on the movable die tooth plate, thereby affecting the processing quality. In the process of smearing, the debris on the movable die tooth plate is cleaned to avoid leaving metal debris, thereby improving the processing quality of the bolt.

[0026] 4. A flat cup anti-slip bolt rod knurling thread rolling device and its use method. When the rotating disk drives the connecting rod to rotate, the movable mold knurling plate contacts the L-shaped push plate, and the L-shaped push plate pushes the movable plate into the cleaning box for extrusion. The gas in the cleaning box is transmitted to the injection pipe through extrusion, and the extruded gas is discharged through the injection pipe. The discharged gas cleans and cools the movable mold knurling plate, thereby increasing the service life of the device and achieving high-precision processing of knurling and knurling.

[0027] 5. A flat cup anti-slip bolt rod knurled thread roller and a method of using the same.
