Abstract
The invention discloses a hole flanging forming die for suspended support reinforcing plates. The hole flanging forming die comprises an upper die plate, a lower die plate, guide sleeves, guide columns and a die handle. The lower die plate is fixedly provided with concave dies. A piece retreating device is arranged in the concave dies. A plurality of lower equal-height screws are fixedly connected between the lower die plate and the bottom end of the piece retreating device. The bottom of the upper die plate is fixedly provided with a fixing plate. The fixing plate is fixedly provided with material pressing plates matched with the concave dies and a convex die matched with the piece retreating device. The concave dies are provided with screw holes and provided with positioning pins in a screwed mode. The bottoms of the material pressing plates are provided with positioning holes matched with the positioning pins. The hole flanging forming die is reasonable in structure, low in manufacturing cost, short in manufacturing cycle and good in reliability, the stability of hole flanging forming of the suspended support reinforcing plates is improved, and production efficiency is improved.
Description
Technical field
The present invention relates to auto parts and components production and processing mould applications, specifically a kind of burring hole forming die of mounting bracket stiffener.
Background technology
Mounting bracket stiffener is as the little parts on automobile, and its structure is comparatively simple.In prior art, the most complex structure of the burring hole forming die for processing mounting bracket stiffener, cost of manufacture is higher, and the less stable of the mounting bracket stiffener processed, production efficiency is also lower.
Summary of the invention
The object of the invention is the defect in order to overcome prior art existence and deficiency, a kind of burring hole forming die of mounting bracket stiffener is provided.
Technical scheme of the present invention is as follows:
A kind of burring hole forming die of mounting bracket stiffener, include upper and lower template, guide pin bushing, guide pillar and die shank, it is characterized in that: described lower bolster is installed with die, be provided with back pieces device in described die, between the bottom of described lower bolster and described back pieces device, be fixedly connected with multiple lower contour screw respectively; The bottom of described cope match-plate pattern is installed with fixed head, described fixed head is installed with respectively the holding pad matched with described die and the punch matched with described back pieces device; Described die is provided with screw and is screwed with alignment pin, and the bottom of described holding pad is provided with the locating hole matched with described alignment pin.
The burring hole forming die of described mounting bracket stiffener, is characterized in that: described lower bolster is provided with spring eye and is provided with discharging spring, and the top of described discharging spring leans in the bottom of described back pieces device.
The burring hole forming die of described mounting bracket stiffener, is characterized in that: be fixedly connected with contour screw between the top of described cope match-plate pattern and described holding pad.
The burring hole forming die of described mounting bracket stiffener, is characterized in that: be provided with binder spring between the top of described cope match-plate pattern and described holding pad.
Beneficial effect of the present invention:
1, the present invention adopts contour screw to connect back pieces device and lower bolster, makes coordinating more reliably between punch with back pieces device, improves the stability of mounting bracket stiffener hole-crimped forming.
2, the present invention adopts die to match with back pieces device with holding pad and punch, makes mounting bracket stiffener hole-crimped forming, and structure is more reasonable, and cost of manufacture is low, and fabrication cycle is short.
3, the present invention is by arranging alignment pin, locating hole, contour screw and binder, discharging spring, make die and holding pad and the compatible degree between punch and back pieces device high, hole-crimped forming for mounting bracket stiffener provides reliable guarantee, improves production efficiency.
