Product description

Hub bolts are high-strength bolts that connect vehicles to the wheels. The connection location is the hub unit bearing of the wheel! Generally, class 10.9 is used for mini-medium vehicles, class 12.9 is used for large-sized vehicles! The structure of the hub bolt is generally a knurled key file and a threaded file! And a hat head! Most of the T-shaped head wheel bolts are above 8.8 grade, which bears the large torsion connection between the car wheel and the axle! Most of the double-headed wheel bolts are above grade 4.8, which bear the lighter torsion connection between the outer wheel hub shell and the tire.

Cold heading forming of high-strength bolts

Usually the bolt head is formed by cold heading plastic processing. The cold heading forming process includes cutting and forming, single-station single-click, double-click cold heading and multi-station automatic cold heading. An automatic cold heading machine performs multi-station processes such as stamping, heading forging, extrusion and diameter reduction in several forming dies.
(1) Use a semi-closed cutting tool to cut the blank, the easiest way is to use a sleeve type cutting tool.
(2) During the transfer of short-sized blanks from the previous station to the next forming station, the fasteners with complex structures are processed to improve the accuracy of the parts.
(3) Each forming station should be equipped with a punch return device, and the die should be equipped with a sleeve-type ejector device.
(4) The structure of the main slider guide rail and process components can ensure the positioning accuracy of the punch and the die during the effective use period.
(5) The terminal limit switch must be installed on the baffle that controls the material selection, and attention must be paid to the control of the upsetting force.
