On the electric power loop for joining the power driving cylinder for being connected to cylinder grade pressing mold；When the outer barrel lower end of cylinder grade pressing mold is pressed in nut seat
The lug of hemisphere grade hole upper port is after, if pressure suffered in two No. three squeeze buttons is respectively in setting extruding force
More than when, then two No. three squeeze disconnect switch is in off-state so that the Powered Propulsion gas of cylinder grade pressing mold
The electric power loop of cylinder is off, and the power driving cylinder of cylinder grade pressing mold is stopped, and cylinder grade pressing mold stops downward
Mobile, cylinder grade pressing mold terminates the squeeze job to nut seat hemisphere grade hole upper port lug edge.
It is this by two No. three squeeze disconnect switch limit method come the power driving cylinder to cylinder grade pressing mold into
The automatically controlled mode of row power on/off, ensure that cylinder grade pressing mold to nut seat hemisphere grade hole upper port lug along extruding degree, significantly
Improve the reliability of nut seat hole strength.
Preferably, the angle of conical section is 40-45 degree.The nut seat circular cone grade that the conical section of this angled arrangement is got
The lug of hole open upper end is uniform along thickness, so as to ensure that the nut seat hole strength that following process goes out is high.
The present invention can reach following effect：
The nut bore that the present invention makes is there is no tilting, and the center line of nut bore, which is not present, to be tilted, nut bore
For center line on same straight line, the lug of nut seat outer end of hole mouth surrounding is uniform along thickness, and nut seat hole strength is high.This hair
Bright at low cost, production efficiency is high, and reliability is high.

It is as follows suitable for the production method of nut bore producing device：
The medial surface of wheel spoke is fixedly mounted on horizontally disposed lower template upper surface, and punching die hole is allowed to be directed at vehicle
Wheel spoke needs to beat at nut bore；Then screw rod grade is punched punch-pin column from the wheel spoke upper table directly over punching die hole
Face is punched down vertically, and screw rod grade punching punch-pin column lower end is allowed to enter vertically into punching die hole, so as in wheel spoke
On get nut seat screw rod grade hole (30), get and screw rod grade punching punch-pin column removed behind nut seat screw rod grade hole；Then pass through
Guide screw bar and locking nut are pressed abd fixed on No.1 ring shaped die mold plate on wheel spoke upper surface, then allow No.1 screw rod
Section enters the inner ring of circular cone grade punching punch-pin column from No.1 ring shaped die mold plate in nut seat screw rod grade hole downward, by circular cone
Section carries out the upper port in nut seat screw rod grade hole circular cone grade with circular cone grade punching punch-pin column and squeezes punching, so as in nut seat spiral shell
The upper port in bar grade hole gets nut seat circular cone grade hole (31), and the depth in nut seat circular cone grade hole is nut seat screw rod grade hole
0.3-0.5 times of depth removes circular cone grade punching punch-pin column after getting nut seat circular cone grade hole；Then No. two spiro rod section courts are allowed
The lower inner ring hemisphere grade punching punch-pin column from No.1 ring shaped die mold plate is entered in nut seat circular cone grade hole, by No. two hemisphere
Section carries out nut seat circular cone grade hole hemisphere grade with hemisphere grade punching punch-pin column and squeezes punching, so as in nut seat circular cone grade hole
Nut seat hemisphere grade hole (32) is got, and the bottom in nut seat hemisphere grade bottom hole end and nut seat circular cone grade hole is in same level
On face, hemisphere grade is punched punch-pin column respectively after getting nut seat hemisphere grade hole and No.1 ring shaped die mold plate is removed；Then pass through
Guide screw bar and locking nut are pressed abd fixed on No. two ring shaped die mold plates on wheel spoke upper surface；Then No. three screw rods are allowed
Section makes the outer surface of No. three hemisphere sections closely be adjacent to after positioning punch-pin column is entered from the inner ring of No. three ring shaped die mold plates downward
On the inner wall in nut seat hemisphere grade hole, and by No. three spiro rod sections and fastening bolt handle stretched out from nut seat screw rod grade hole lower end
Positioning punch-pin column is fixed；Then the inner cylinder of cylinder grade pressing mold is allowed to be sleeved on positioning punch-pin column and is pressed down can be nut seat half
The lug of ball grade hole upper port squeezes down along (33), stops cylinder grade when the outer barrel lower end of cylinder grade pressing mold is squeezed
The pushing of pressing mold is that positioning punch-pin column presses down the result is that so that lug is lower along height, so that nut seat hemisphere grade
The lug of hole upper port is equal along height.
The vertical bar (34) with the centerline parallel of screw rod grade punching die hole is equipped with below lower template, in vertical bar
Adjustable sliding is fixed with baffle (35), and the upper surface of baffle is perpendicular to the center line of screw rod grade punching die hole, gear
Plate is arranged with screw rod grade punching die hole face；The bottom of No.1 spiro rod section is equipped with No.1 half-via (36), in No.1 half-via
In be equipped with No.1 squeeze disconnect switch (37), No.1 squeeze disconnect switch No.1 squeeze buttons (38) stretch out No.1 half-via outside
0.05-0.1 millimeters, and the pressure that the No.1 squeeze buttons of No.1 extruding disconnection switch are subject to is when setting more than extruding force one
It number squeezes and to disconnect switch and be off, No.1, which squeezes, to be disconnected the pressure that is subject to of No.1 squeeze buttons of switch and be less than setting and squeeze
During pressure No.1 squeeze disconnect switch it is in the conduction state, No.1 squeeze disconnect switch is connected in series in circular cone grade punching punch-pin column
Power driving cylinder (39) electric power loop (40) on；
After the bottom of the No.1 spiro rod section of circular cone grade punching punch-pin column is pressed on baffle, if suffered in No.1 squeeze buttons
Pressure set extruding force more than when No.1 squeeze disconnect switch be off so that circular cone grade punch punch-pin column
The electric power loop of power driving cylinder be off, the power driving cylinder of circular cone grade punching punch-pin column is stopped,
The punching punch-pin column stopping of circular cone grade moves down, and circular cone grade punching punch-pin column terminates to the nut seat circular cone grade hole of wheel spoke
Drilling operation.This squeezed by No.1 disconnects the limit method of switch to punch the power driving cylinder of punch-pin column to circular cone grade
Carry out the automatically controlled mode of power on/off, as long as adjust baffle upper surface to lower template screw rod grade punching die hole lower port away from
Depth from the i.e. controllable nut seat circular cone grade hole got improves the reliability of nut seat hole strength.
The bottom of No. two spiro rod sections is equipped with No. two half-vias, and No. two extruding disconnections are equipped in No. two half-vias and are switched, and two
It number squeezes and to disconnect No. two squeeze buttons of switch to stretch out No. two half-vias 0.05-0.1 millimeter outer, and No. two squeeze to disconnect and switch
The pressure that is subject to of No. two squeeze buttons squeeze when setting more than extruding force and disconnect switch and be off for No. two, No. two are squeezed
It breaks out when the pressure that No. two squeeze buttons of switch are subject to is less than setting extruding force No. two and squeezes and disconnect switch and be on shape
State, No. two squeeze on the electric power loop for disconnecting the power driving cylinder that switch is connected in series in hemisphere grade punching punch-pin column；When half
After the bottom of No. two spiro rod sections of ball grade punching punch-pin column is pressed on baffle, if pressure suffered in No. two squeeze buttons exists
No. two extruding disconnect switch and are off when more than setting extruding force, so that the power of hemisphere grade punching punch-pin column pushes away
