Abstract

The utility model discloses a U-shaped iron flanging sizing die, which comprises a movable die plate (2), a fixed die plate (1), a blanking die (8), an ejector rod (7), a sizing female die (5) and a beating device. The blanking die (8) and the ejector rod (7) are connected with the fixed die plate (1), the sizing female die (5) and the beating device are connected with the movable die plate (2), the beating device comprises a beating rod (3) and a beating cushion core (4), a plurality of downward projections (6) are disposed at the bottom of the beating cushion core (4), the amount and the position of the projections (6) correspond to those of holes on a finished product of U iron one by one, the lower portions of the projections (6) are big end up and conical, and an axis of each conical lower portion is coaxial with the corresponding hole on the finished product of U iron. The U-shaped iron flanging sizing die is high in position precision when the U-shaped iron is drilled and machined.

Description

U iron curring and sizing die

Technical field

The utility model relates to a kind of mould, specifically is a kind of U iron curring and sizing die.

Background technology

At present, loudspeaker generally adopts the moulding of mould stamping cold forging with U iron.In the process of U iron moulding, need carry out flanging and restriking to it handles, the U iron flanging and restriking mould of prior art, its structure generally comprises moving platen, solid plate and the concavo-convex mould and the Lifting Device that are connected with solid plate, correcting die that is connected with moving platen and filling device, described filling device comprises knockout rod and dnockout bedding core, the bottom of this dnockout bedding core is the plane, at U iron after curring and sizing die processing, the processing of holing in plane after also will processing U iron economy-combat backing strap core, add man-hour in boring, the center in hole is difficult to find accurately really, and therefore the positional precision in the hole after the processing is lower, influences the assembly precision of product.

The utility model content

The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of U anvil hole that can make to add the high U iron curring and sizing die of positional precision in man-hour.

Technical solution of the present utility model is, a kind of U iron curring and sizing die with following structure is provided: it comprises moving platen, solid plate and the concavo-convex mould and the ejector beam that are connected with solid plate, correcting die that is connected with moving platen and filling device, described filling device comprises knockout rod and dnockout bedding core, the bottom of described dnockout bedding core is provided with a plurality of to lower convexity, and the quantity and the position in hole are corresponding one by one on the quantity of projection and position and the finished product U iron, the taper that the bottom of described a plurality of projectioies is all big up and small down, and corresponding hole coaxial line on the axis of each taper and the finished product U iron.

After adopting above structure, the utility model U iron curring and sizing die compared with prior art, have the following advantages: employing is provided with a plurality of to lower convexity in the bottom of dnockout bedding core, and the quantity and the position in hole are corresponding one by one on the quantity of projection and position and the finished product U iron, the taper that the bottom of described a plurality of projectioies is all big up and small down, and corresponding hole coaxial line on the axis of each taper and the finished product U iron.This projection stamps out U iron top a plurality of indents that match with hole on the finished product U iron when U iron flanging and restriking, add man-hour in the hole of carrying out on the U iron, need not carry out the location in hole, only need get final product by the processing that the hole is carried out in the position of indent, can well guarantee the positional precision in U iron hole like this, alleviate mach workload simultaneously, improved operating efficiency.
