Two crawler belt cam continuous stamping die
Technical field
The present invention relates to cold bending punching press industrial circle, particularly relate to a kind of two crawler belt cam continuous stamping die.
Background technology
Cold bending punching press field is a considerable job in modern manufacturing industry, existing technology completes stamping procedure by traditional diel, but in this traditional approach punching course cold bending must out of service or keep geo-stationary, automaticity is not high, can not realize continuous stepless continuous productive process, operating efficiency is lower; In order to solve the problem, this area working technical staff wishes a kind of two crawler belt cam continuous stamping die of design always, to realize continuous stepless press work.
Summary of the invention
In order to solve the problem, enhance productivity, realize continuous stepless press work, the present invention devises a kind of two crawler belt cam continuous stamping die.
Technology contents of the present invention is: a kind of two crawler belt cam continuous stamping die, and comprise two Athey wheels and the blanking mechanism composition of corresponding setting up and down, two corresponding up and down Athey wheels are all assemblied on sprocket wheel by crawler belt and form; Described crawler belt forms by chain block is hinged, and the chain block on upper and lower Athey wheel is mutually corresponding; Upper caterpillar chain block is provided with patrix, and corresponding lower caterpillar chain block is provided with counterdie, and upper and lower mould is provided with corresponding punching;
Blanking mechanism is made up of cam and punch, and be provided with the fixed head connected by support in the middle part of upper Athey wheel, fixed head is provided with guide hole, and the punch die matched with punching set by the upper and lower mould of crawler belt coordinates and is placed in fixed head guide hole; Corresponding punch upper end is provided with cam.
Connected by connecting axle between each chain block, sprocket wheel is provided with the breach of corresponding connecting axle; Punch die is stepped for what reduce successively from top to bottom; Fixed head is provided with the guide hole of corresponding punch die external diameter, and inside is provided with the discharging spring of corresponding punch die; Cam eccentric is apart from matching with the impulse stroke of punch die;
The upper and lower mould of crawler belt is connected on corresponding chain block by the bolt matched; Crawler belt patrix is fixedly connected with outwardly alignment pin, and counterdie is provided with the pin-and-hole matched with alignment pin; Below described crawler belt, corresponding punch is provided with ash can.
Beneficial effect
This apparatus structure is simple, easy to operate, utilizes crawler belt cam press structure, realizes continuous stepless continuous productive process, improve production efficiency.

Detailed description of the invention
See Fig. 1-4: a kind of two crawler belt cam continuous stamping die, comprise two Athey wheels and the blanking mechanism composition of corresponding setting up and down, two corresponding up and down Athey wheels are all assemblied on sprocket wheel by crawler belt and form; Described crawler belt forms by chain block is hinged, and the chain block on upper and lower Athey wheel is mutually corresponding; Upper caterpillar chain block is provided with patrix, and corresponding lower caterpillar chain block is provided with counterdie, and upper and lower mould is provided with corresponding punching;
Blanking mechanism is made up of cam and punch, and be provided with the fixed head connected by support in the middle part of upper Athey wheel, fixed head is provided with guide hole, and the punch die matched with punching set by the upper and lower mould of crawler belt coordinates and is placed in fixed head guide hole; Corresponding punch upper end is provided with cam.
Connected by connecting axle between each chain block, sprocket wheel is provided with the breach of corresponding connecting axle; Punch die is stepped for what reduce successively from top to bottom; Fixed head is provided with the guide hole of corresponding punch die external diameter, and inside is provided with the discharging spring of corresponding punch die; Cam eccentric is apart from matching with the impulse stroke of punch die;
The upper and lower mould of crawler belt is connected on corresponding chain block by the bolt matched; Crawler belt patrix is fixedly connected with outwardly alignment pin, and counterdie is provided with the relative positional accuracy that the pin-and-hole matched with alignment pin ensures corresponding upper and lower mould; Below described crawler belt, corresponding punch is provided with ash can.
Two crawler belt cam continuous stamping die can be placed in cold bending front end, as front stamping procedure, also can be placed in cold bending rear end, as rear stamping procedure; Sprocket rotation drives crawler belt and workpiece to push ahead; Be provided with punch in the middle part of crawler belt, set by punch and chain block patrix, pilot hole matches; Corresponding punch die is provided with cam, cam is corresponding with sprocket wheel by transmission mechanism, crawler belt cam after a chain block of often advancing forward rotates one week, promote punch in cam rotation process to advance downwards, punching press is carried out to workpiece, punch is provided with discharging spring, and rebound punch reset mode after punch completes stamping-out, completes a press work; Workpiece after stamping-out is advanced forward along with crawler belt, repeats punching press action, until workpiece all departs from crawler belt; Described punching is through hole, and the waste material that stamping-out falls falls into ash can through punching.
