Abstract
The invention discloses a computer case deburring die structure, which comprises an upper die part and a lower die part. The computer case deburring die structure is characterized in that a deburring sinking die is thinner than a lower template and is smaller than the product appearance, and the periphery of a sinking die hole of the lower template, which is provided with a burr sinking die, is chamfered with an angle of 30-60 degrees. The computer case deburring die structure disclosed by the invention has the advantages of simple structure and high automation degree, the rejection rate of the product is lowered, and the product precision requirement is guaranteed.
Description
Technical field
The present invention relates to the mould in the machining, specifically is exactly a kind of computer chassis Burr removal mold structure.
Background technology
Computer is the electronic product commonly used in people's daily life, computer chassis generally all is to make of stainless steel and other metal materials, the shaping of the metal material at present normal mode that adopts is to utilize diel that metal material is formed according to Sheet Metal Forming Technology, the computer chassis product is because required precision is higher, burr can appear in the character decision owing to metal material itself in punching course, burr can produce great impact for the precision of computer chassis, can carry out follow-up deburring to computer chassis traditionally processes, but because material thickness is thinner, artificial follow-up deburring not only can affect the flatness requirement of product, also can increase the percent defective of product, increase production cost control.
Summary of the invention
Technical problem to be solved by this invention is a kind of computer chassis Burr removal mold structure of design, and the present invention is simple in structure, and automaticity is high, has reduced the qualification rate of product, and has guaranteed the required precision of product.
Technical scheme
A kind of computer chassis Burr removal mold structure, it comprises part of the upper die and part of the lower die, the part of the upper die comprises upper bolster, upper padding plate, punch retainer, baffle plate, holding pad, the part of the lower die comprises lower bolster, lower bolster, die shoe, the deburring die, upper bolster, upper padding plate and punch retainer are fixed together successively, baffle plate and holding pad are fixed together and are contained in the punch retainer lower end with unloading bolt afterwards, lower bolster, lower bolster and die shoe are fixed together successively, it is characterized in that: described deburring die is contained on the lower bolster, the deburring die is thinner than lower bolster, the burr die is less than product design, 30 degree is arranged to 60 degree angles around the die hole of lower bolster dress burr die.
Described deburring die is thicker than thin 1/3～1/2 material of lower bolster.
Described burr die is thicker than little 1/3～1/2 material of product design.
Described upper bolster, upper padding plate and punch retainer are fixing successively with pin.
Described baffle plate and holding pad are fixed together with pin.
Described lower bolster, lower bolster and die shoe are fixed together with pin.
Described lower bolster fovea superior nib is comprised of four interchangeable mold inserts.
Locating piece is housed around the described die hole.
Beneficial effect
Need the shaping computer chassis put into the present invention from last process and locate, move downwards at forcing press effect bed die, holding pad is pushed down product, and the product introduction die hole because die hole is less than product, is removed burr under pressure.The present invention is simple in structure, and automaticity is high, has reduced the qualification rate of product, and has guaranteed the required precision of product.
Description of drawings
Accompanying drawing 1 is computer chassis Burr removal mold new construction schematic diagram of the present invention.
Accompanying drawing 2 is the local enlarged diagrams of computer chassis Burr removal mold of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further set forth the present invention.
Shown in attached Fig. 1 and 2, a kind of computer chassis Burr removal mold structure, it comprises part of the upper die and part of the lower die, the part of the upper die comprises upper bolster 1, upper padding plate 2, punch retainer 3, baffle plate 4, holding pad 5, the part of the lower die comprises lower bolster 6, lower bolster 7, die shoe 8, deburring die 9, upper bolster 1, upper padding plate 2 and punch retainer 3 are fixed together successively, baffle plate 4 and holding pad 5 are fixed together and are contained in punch retainer 3 lower ends with unloading bolt afterwards, lower bolster 6, lower bolster 7 and die shoe 8 are fixed together successively, wherein, described deburring die 9 is contained on the lower bolster 6, deburring die 9 is thicker than lower bolster 6 thin 1/3～1/2 material, deburring die 9 is thicker than little 1/3～1/2 material of product design, 30 degree are arranged to 60 degree angles around the die hole of lower bolster 6 dress deburring dies 9, upper bolster 1, upper padding plate 2 and punch retainer 3 usefulness pins are fixing successively, baffle plate 4 and holding pad 5 usefulness pins are fixed together, lower bolster 6, lower bolster 7 and die shoe 8 usefulness pins are fixed together, lower bolster 6 fovea superior nibs are comprised of four interchangeable mold inserts, and locating piece 10 is housed around the die hole.
Need the shaping computer chassis putting into the present invention from last process locates, move downwards at forcing press effect bed die, holding pad is pushed down product, the product introduction die hole, because die hole is less than product, and around the mould sky chamfering is arranged, under pressure the product burr is removed, reach the purpose of deburring, the present invention is simple in structure, automaticity is high, has reduced the percent defective of product, and has guaranteed the required precision of product.
