Description

Copper strips fluting mould Technical Field The utility model relates to the technical field of slotting dies, in particular to a copper strip slotting die. Background In the process of machining the Australian brass plug, a copper strip with the thickness of 6.3mm multiplied by 1.6mm is used for machining, the thickness of 1.6mm of the middle part of the product is reduced to 1.0mm for circumferential encapsulation, a stamping line is used for producing a copper sheet with the thickness of 6.3mm multiplied by 1.6mm multiplied by 24mm, and an automatic slot milling machine is used for double-side milling to achieve the thickness of 1.0 mm. The production mould of the automatic slot milling machine in the prior art has the following defects: 1. the limit production capacity of the automatic slot milling machine is 12000, one man is needed, and the production efficiency is low; 2. In order to avoid jamming on a rail of a slot milling machine after stamping, the product needs to be firstly ground with burrs, then milled flat, then ground with burrs, then stamped on two sides, and finally processed in 5 steps, wherein the processing is complex; 3. the automatic slotting machine has double-sided slotting, symmetry exceeding 0.05mm, high encapsulation defective rate and high rejection rate. The utility model provides a copper strip grooving die. Disclosure of Invention The utility model aims to solve the defects in the prior art and provides a copper strip slotting die. In order to achieve the purpose, the utility model adopts the following technical scheme that the copper strip slotting die comprises: The upper die comprises an upper cover plate, an upper die seat, an upper base plate and an upper die plate, wherein the top of the upper die plate is fixedly arranged at the bottom of the upper base plate, the top of the upper base plate is fixedly arranged at the bottom of the upper die seat, and the top of the upper die seat is fixedly arranged at the bottom of the upper cover plate; The middle die comprises a stop plate and a stripper plate, and the bottom of the stop plate is fixedly arranged at the top of the stripper plate; The lower die comprises a lower die plate, a lower base plate and a lower die holder, wherein the bottom of the lower die plate is fixedly arranged at the top of the lower base plate, and the bottom of the lower base plate is fixedly arranged at the top of the lower die holder.
