Abstract
The utility model is related to a NC turret punch machine anti-scrap rebound device, in particular to a safety device in metal sheet processing equipment. The safety device is arranged under the discharge mouth of a NC turret punch machine working table and is composed of a scrap suction pipe, a barrel-shaped scrap suction seat, a scrap suction seat gate and an underpressure generator. The scrap suction pipe is respectively communicated with the working table discharge mouth thereon and the scrap suction seat therebelow; the scrap suction seat is provided with at the side face of the scrap suction seat gate and the underpressure generator is communicated with the scrap suction seat cylinder cavity. The utility model is arranged with an underpressure suction port under the working table discharge port. After the punching shear of the sheet, the scrap bottom face of the lower die orifice drops due to the underpressure effect, which avoids the scrap rebounding or prevents the lower die orifice from being absorbed by the upper die. The utility model is arranged under the discharge mouth, which overcomes that the prior art requires to provide an air hole at the center of the upper die, thus decreasing the die strength. The utility model has high reliability and good use effect.
Description
Technical field
The utility model relates to the safety device in the metal blank process equipment, relates in particular to the safety device that the following die orifice that can guarantee the NC turret punch machine mould is not covered by waste material.
Background technology
NC turret punch machine is when carrying out the punching operation, and the operating frequency of patrix is very high, and speed is very fast.Patrix moves on rapidly after the punching, and can form instantaneous negative pressure between patrix and the blanking this moment, and this negative pressure can make blanking with moving on the patrix and taken out of lower die orifice.If the waste material of taking down die orifice out of is fallen down one side of die orifice, several situations below can when ensuing punching is moved, taking place; One, the compressive strain of working plate backing strap is scrapped; Two, when a blanking part covers die-cut mouthful, unbalance loading can occur processing, when unbalance loading is serious the serious consequence that cutting edge bursts can take place; If three, take out of down die orifice waste material half be stuck in the workpiece hole, when half is stuck in down in the nib, clamp can take place and draw seriously equipment breakdown such as position, plate bump clamp and guard shield in the feed mechanism friction feeding.
The disclosed application number of State Intellectual Property Office is 03278096.6, and name is called the patent documentation of " digitally-controlled press machine air blowing type patrix ", discloses a kind of air flue of establishing in patrix, adopts barotropic gas restriction blanking to move to the lip-deep technology of counterdie.When carrying out the punching operation, blow downwards by the gas hole on the upper mold core by control device in blanking moment, make waste material break away from patrix, fall downwards, prevented the bounce-back of waste material effectively.This technology has solved preferably the waste material bounce-back or has been arrived the lip-deep problem of counterdie by negative-pressure adsorption, but the complex structure of this technology, the cost height, patrix processing is difficult for, and has the defective of patrix strength decreased.
The utility model content
The utility model provides a kind of work in-process can effectively prevent the waste material bounce-back or has been adsorbed out the anti-waste material rebounding device of NC turret punch machine of die orifice down.
The technical solution of the utility model is: it is arranged on digital control turret punch workbench discharging opening below, and it is made up of waste suction pipe, tubular waste suction seat, waste suction seat door, depression generator; The waste suction pipe is communicated with the workbench discharging opening of its top and the waste suction seat of below respectively; Be provided with waste suction seat door in waste suction seat side, depression generator is communicated with the tube chamber of waste suction seat.
Described waste suction seat door is connected with cylinder.
Described waste suction seat bottom is provided with the inclined-plane.
Described depression generator is made up of vavuum pump and flexible pipe, is provided with connector in waste suction seat side, and flexible pipe is connected with connector.
The utility model is provided with the negative pressure suction inlet below the workbench discharging opening, after plate was punched, the bottom surface of waste material was subjected to suction function in the lower die orifice, fell, the phenomenon of having avoided the waste material bounce-back or having been adsorbed lower die orifice by patrix.Be arranged on the discharging opening below, overcome in the prior art and need establish pore at the patrix center, thus the problem of reduction patrix intensity.The utility model reliability height, result of use is good.

The specific embodiment
Such as Fig. 1, the utility model is arranged on digital control turret punch workbench discharging opening below, and it is made up of waste suction pipe 9, tubular waste suction seat 6, waste suction seat door 5, depression generator; Waste suction pipe 9 is communicated with the workbench discharging opening of its top and the waste suction seat 6 of below respectively; Be provided with waste suction seat door 5 in waste suction seat 6 sides, depression generator is communicated with the tube chamber of waste suction seat 6.
Waste suction seat door 5 is connected with cylinder 4.Control the switch of waste suction seat door 5 by cylinder 4.
For making things convenient for the discharging of waste material 3, waste suction seat 6 bottoms are provided with the inclined-plane.
Depression generator is made up of vavuum pump 8 and flexible pipe 7, is provided with connector in the useless seat of suction 6 sides, and flexible pipe 7 is connected with connector.
In the utility model when work,, patrix 1, counterdie 2 work form waste material 3 in 2 mouthfuls of counterdies, and waste material 3 is subjected to the effect of waste suction pipe 9 interior negative pressure, falls in the waste suction seat 6.Run up to a certain amount of after, vavuum pump 8 is shut down, waste suction seat door 5 is opened in cylinder 4 work, the waste material 3 that is accumulated on the inclined-plane, waste suction seat 6 bottom slides out.
