Description
Technical field
The invention belongs to the cut-out technical fields of opening profile, and in particular to a kind of shearing tool of opening profile.
Background technology
In the no waste mine shearing of existing opening profile, when plate thickness is more than 4mm, since shearing force increases, to improve
The bearing capacity and service life of cutter, cutter thickness need to increase, and directly result in the weight weight of cutter hub in this way, of high cost, more
Change time-consuming and laborious, quenching is yielding, and punching is difficult, and difficulty of processing is big, the defects of wasting material, separately due to cutter part by
Power situation is bad, it may appear that cutter part blade mouth crack or fracture directly affect the Homes Using TV of production line, reduce yield.
It is thick increasing cutter according to experience early period in the c-type cold-forming shapes no waste mine molding shearing tool designed in the past
While spending, increases cutter reinforcing plate on the outside of cutter for increasing cutter intensity, prevent cutter from deforming, make entire cutter stress
More uniformly, cutter part blade mouth crack is avoided.However additional cutter reinforcing plate is found in actual use subsequent
The effect of tool life well can not be played, cutter neck cutting edge still can occur in use for some time
It bursts apart, analyzes its reason and be that cutter has burst apart before playing reinforcement effect in cutter securing plate, due to the hardness of cutter
Higher, deflection has burst apart before cutter securing plate works, therefore early period, design did not played ideal using effect,
It is therefore desirable to current cutter be further improved to improve its using effect.
