Abstract
Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of U-shaped bracket piercing die.
Background technology
U-shaped support is parts conventional in automobile, and it is the part be connected with vehicle body for vehicle frame, and play stable reinforcement, increase safeguard protection performance, therefore technical requirement is higher.
At present, U-shaped support processing is split production, is welded, then holes by a few block plate.This preparation method, the uniformity of part processing is poor, and dimensional accuracy can not meet technical requirement, even if process, coordinate with vehicle frame and vehicle body and can not reach identical state, borehole accuracy is not high, and presentation quality is poor, production efficiency is on the low side, and cost of manufacture is higher, and security is low.
Utility model content
The utility model its object is to provide a kind of U-shaped bracket piercing die, completes U-shaped cradle top and two side punchings, and then improves the quality of products, and reduces production cost.
For realizing the utility model object, the technical scheme of employing is:
A kind of U-shaped bracket piercing die, comprise upper bolster and die shoe, it is characterized in that, upper bolster lower end is provided with installing plate, punching concave die is provided with between installing plate and die shoe, bottom and the die shoe of punching concave die are fixed, the top of punching concave die is provided with holding pad, holding pad is provided with pull bar, the top of pull bar is arranged in upper bolster through installing plate, the outer wall of pull bar is sheathed with spring, the two ends of spring contact with installing plate with holding pad respectively, die shank is provided with in upper bolster, the bottom of die shank is arranged in the cavity of fixing wedge through upper bolster, the bottom of die shank is fixed with piercing punch, piercing punch is arranged in punching concave die through after cavity and holding pad.Both sides, die shoe upper end are provided with gathering sill, gathering sill is respectively arranged with pressure strip and movable wedge, spring is provided with between pressure strip and movable wedge, spring one end is connected with pressure strip, the other end is connected with movable wedge, pressure strip is fixedly connected with die shoe by hex screw, movable wedge is provided with drift, pressure strip upper end is provided with through hole, through hole is consistent with forcer position, movable wedge top is provided with inclined-plane, fixing wedge is provided with between upper bolster and die shoe, fixing wedge upper end is connected with installing plate and upper bolster by hex screw, fixing wedge lower end is provided with inclined-plane.
Further, the bottom of described upper bolster is provided with upper guide bush, and the top of die shoe is provided with lower guide pin bushing, is provided with guide pillar between upper guide bush and lower guide pin bushing, the two ends of guide pillar are separately positioned in upper guide bush and lower guide pin bushing, and the dead in line of the axis of the axis of guide pillar, upper guide bush, lower guide pin bushing.
The beneficial effects of the utility model: complete U-shaped cantilever tip and two side punchings by this mould, avoid the position occurring machining hole to occur comparatively big error, and improve machining accuracy and the production efficiency in hole, production cost is lower, and security is high.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of U-shaped bracket piercing die.
Detailed description of the invention
