The trimming and piercing die of quarter window stiffener on a kind of processing automobile
Technical field
The present invention relates to the manufacture field of auto parts machinery, relate in particular to the trimming and piercing die of quarter window stiffener on a kind of processing automobile.
Background technology
The quarter window stiffener is positioned at body forward structure on the automobile, is a high-strength galvanized sheet spare, plays the sheet metal component of booster action at the A post.The processing method of original triangle window stiffener is: stretching, deburring, punching, now deburring and punching are finished in same operation, production efficiency is not high, because the profile of quarter window stiffener is irregular, the processing of deburring die is very complicated, is difficult to guarantee crudy, causes the deburring burr large, not attractive in appearance, the mold use life-span is short.
Summary of the invention
The trimming and piercing die that the purpose of this invention is to provide quarter window stiffener on a kind of processing automobile, this mould structure is reasonable, can improve product quality and production efficiency, and reduces production costs, and improves service life.
The present invention is achieved in that the trimming and piercing die of quarter window stiffener on a kind of processing automobile, comprise on top mold frame, upper die plate, the lower mold holder and be provided with the deburring punch by the deburring punch retainer, it is characterized in that: be provided with the deburring die below the described upper die plate, be provided with the deburring holding pad in the deburring die, be provided with several nitrogen springs between deburring holding pad and the upper die plate, also be provided with the piercing punch fixed head between deburring holding pad and the upper die plate; Described deburring punch outer ring is provided with waste knife.
Be provided with the deburring die plate insert in the deburring die of the present invention, the deburring die plate insert is comprised of two die plate insert A, die plate insert B and die plate insert C and die plate insert D, die plate insert E, die plate insert F, die plate insert G, die plate insert H.
Be provided with several punching concave die B, punching concave die A on the deburring punch of the present invention.
The present invention is rational in infrastructure, has improved product quality and production efficiency, has reduced production cost, improves and has used the life-span.

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing:
With reference to accompanying drawing, the trimming and piercing die of quarter window stiffener on a kind of processing automobile, comprise on top mold frame 1, upper die plate 7, the lower mold holder 15 and be provided with deburring punch 12 by deburring punch retainer 11, it is characterized in that: be provided with deburring die 9 below the described upper die plate 7, be provided with deburring holding pad 6 in the deburring die 9, be provided with several nitrogen springs 5 between deburring holding pad 6 and the upper die plate 7, also be provided with piercing punch fixed head 2 between deburring holding pad 6 and the upper die plate 7; Described deburring punch 12 outer rings are provided with waste knife 10.Be provided with deburring die plate insert 8 in the described deburring die 9, deburring die plate insert 8 is comprised of two die plate insert A8-1, die plate insert B8-2 and die plate insert C8-3 and die plate insert D8-4, die plate insert E8-5, die plate insert F8-6, die plate insert G8-7, die plate insert H8-8.Be provided with several punching concave die B13, punching concave die A14 on the described deburring punch 12.During implementation, deburring holding pad 6 is done to support to do to pump by nitrogen spring 5, the drift of forcing press is made time spent deburring holding pad downwards and stably workpiece is placed on the deburring punch 12, deburring die 9 further moves down with workpiece and contacts, deburring holding pad and deburring punch are with Workpiece clamping, the deburring die further moves down with the deburring punch and overlaps, and makes workpiece reach the trimming and piercing die state.When the drift of forcing press moved up, the deburring holding pad withstood workpiece and is adjacent to the deburring punch, then leaves workpiece with drift.Deburring die of the present invention adopts and is assembled by a plurality of die plate inserts, is convenient to the processing of deburring die, has improved the crudy of deburring die and has used the life-span, has improved product quality.
