Abstract
The utility model discloses a high-speed progressive die for correcting the coplanarity of a lead frame. The high-speed progressive die for correcting the coplanarity of the lead frame comprises a male die and a female die which is matched with the male die. The high-speed progressive die for correcting the coplanarity of the lead frame is characterized in that correcting blocks (1) used for correcting the lead frame are fixed to the male die and the female die respectively, and the two correcting blocks are arranged in a staggered mode in the length direction of the lead frame. According to the high-speed progressive die for correcting the coplanarity of the lead frame, the upper correcting block and the lower correcting block squeeze a lead in a staggered mode during die assembling, as a result, the good levelness of the whole lead is kept, correction of the coplanarity of the lead can be achieved, and the quality of products is improved.
Description
Technical field
The utility model relates to the means for correcting of lead frame coplanarity being proofreaied and correct on high-sped progressive die tool, the especially mould of lead frame production use.
Background technology
Lead frame is the product in high-sped progressive die tool punching molding.The IN-LEAD(lead of the normal lead frame of producing by high-sped progressive die tool) tolerance that coplanarity is sometimes difficult to reach next procedure is (because client will carry out gold ball bonding, lead-in wire difference of height is crossed conference, and to affect its welding wire not firm, the adverse consequences such as fracture of wire), if but by mold integral structure is adjusted, not only the cycle is long, and cost is high, for manufacturing enterprise, be generally difficult to bear.It is TIE-BAR(pull bar that lead-in wire on normal lead frame upwarps larger) two long leads on both sides are easily overproof, therefore can utilize station vacant on mould, indivedual lead-in wires that coplanarity is poor are proofreaied and correct separately, to reach the object of improving the quality of products.
Utility model content
The purpose of this utility model be exactly solve lead frame that high-sped progressive die tool produces because of lead-in wire coplanarity poor, the problem that causes product not satisfy the demands.
For addressing the above problem, the technical solution adopted in the utility model is: the high-sped progressive die tool that lead frame coplanarity is proofreaied and correct, it comprises punch and the die coordinating with punch, it is characterized in that being fixed with respectively punch correcting block and the die correcting block that lead frame is proofreaied and correct on described described punch and die, two correcting blocks are along the dislocation of lead-in wire bar shaped direction.
Adopt technique scheme, mould upper and lower correcting block dislocation in matched moulds process is pushed lead-in wire, thereby makes whole lead-in wire can obtain a well levelness, the Coplanarity Problems that can correct lead-in wire, thus improve the quality of product.
Accompanying drawing explanation
Fig. 1 is the lead-in wire schematic diagram before correcting block is proofreaied and correct.
Fig. 2 is the lead-in wire schematic diagram after correcting block is proofreaied and correct.
The specific embodiment
As shown in Figure 2, the high-sped progressive die tool that lead frame coplanarity is proofreaied and correct, it comprises punch and the die coordinating with punch, is fixed with respectively punch correcting block 1 and die correcting block 3, two correcting blocks that lead frame is proofreaied and correct and misplaces along lead-in wire 2 bar shaped directions on described punch and die.Punch correcting block 1 and die correcting block 3 are arranged on station vacant on mould.
Claims (1)
1. the high-sped progressive die tool that pair lead frame coplanarity is proofreaied and correct, it comprises punch and the die coordinating with punch, it is characterized in that being fixed with respectively punch correcting block (1) and the die correcting block (3) that lead frame is proofreaied and correct on described punch and die, two correcting blocks are along the dislocation of lead-in wire (2) bar shaped direction.
