Description
Technical field
The present invention relates to the improvement invention of a kind of cold header.
Background technology
Cold header is a kind of the various metal wire rods handled well to be carried out cold extrusion, makes metal wire rod equipment of cold-heading molding in mould, is used for processing various standard, non-standard securing member and vapour and rubs accessory.In prior art, the feeding of cold header is by driving arm to move back and forth, and band pawl promotes ratchet-gear wheel intermittent rotary, finally drives drawing-inroller to rotate and carries out feeding.Above-mentioned feed mechanism, structure is complicated, and work noise is big, can not stop feeding during mechanical disorder in time, also frequently occurs that a certain degree of reverse of ratchet-gear wheel, drawing-inroller retreat phenomenon, feed length thus can be occurred inadequate, cause product quality defective.It addition, metal wire rod is generally biscuit before entering cold headers, need to carry out alignment by alignment feature.Current cold headers alignment feature, metal wire rod biscuit can unreel on dish horizontal in loose domain, then stub bar one end is introduced between upper and lower traction wheel, backscrolling by upper and lower traction wheel, first metal wire rod carries out the alignment of vertical direction through vertical alignment wheels, then carries out the alignment of horizontal direction through horizontal alignment wheels.The problem that above-mentioned alignment process exists mainly has: biscuit is the loosest and horizontal placement, take up an area space big, metal wire rod is arbitrarily incorporated between upper and lower traction wheel, and the metal wire rod center of leading-in end is relatively big (including position deviation and angular deviation) with the centre of pull often deviation of upper and lower traction wheel；Further, because the horizontal placement of biscuit, so metal wire rod is circumference bending in horizontal plane, and first having to carry out the alignment of vertical direction by after traction wheel, carry out the alignment of horizontal direction the most again, this is obviously unfavorable for alignment effect.
Summary of the invention
The deficiency existed in view of background technology, the purpose of the present invention is intended to provide a kind of simple in construction, and occupation of land space is little, and fixed length feeding accurately and reliably, can realize the cold header of metal wire rod more preferable alignment effect by the action of backgauge mechanical hand.
The present invention implements by following technical solution:
nullA kind of cold header，Including wire rod alignment feature、Wire rod feeding part、Parts cut off by wire rod、Cold-heading molding parts and front and back lead to parts，It is characterized in that: wire rod feeding part uses finger feed，Including stock support，Stock support is fixedly connected on the feed side of cold headers frame，On stock support, the first fixture block group and the second fixture block group are set along feed direction，First time fixture block of the first fixture block group is fixed on slide，On the first of first fixture block group, fixture block is made up and down setting and is promoted by the first cylinder，First cylinder is fixedly mounted on slide，Slide slides and is located on horizontal guide pillar，Laterally guide pillar fixedly mounts on stock support，The rear end of slide drives arm to be connected with cold headers，Second time fixture block of the second fixture block group is fixed on stock support，On the second of second fixture block group, fixture block is made up and down setting and is promoted by the second cylinder，Second cylinder is fixedly mounted on stock support.
After using technique scheme, the course of action that finger feed realizes is: when feeding forward, on first, metal wire rod is clamped under the effect of the first cylinder by fixture block, now fixture block unclamps metal wire rod on second, so rear driving arm promotes slide reach, realize fixed length feeding, after fixed length feeding, on second, metal wire rod is clamped under the effect of the second cylinder by fixture block, metal wire rod is unclamped by fixture block on first simultaneously, then during driving arm to promote slide to retreat, metal wire rod does not produce retrogressing, it is ensured that feed length keeps consistent every time.In technique scheme, finger feed simple in construction, action is also simple, and fixed length feeding is accurately and reliably.
nullWire rod alignment feature uses mechanical hand to adjust，Including alignment support and the bridging axle being located at alignment support left end，Alignment support is installed the most successively and is provided with upper and lower traction wheel、Vertical alignment wheels and horizontal alignment wheels，The upper up and down setting of traction crop rotation is promoted by pushing up air cylinder，Top air cylinder is arranged on alignment support，The wheel shaft rear end of traction wheel is installed gear and passes through meshed transmission gear up and down，The wheel shaft rear end gear of lower traction wheel is in transmission connection with the output of reducing motor，The charging side of traction wheel is provided with backgauge mechanical hand up and down，Backgauge mechanical hand is bar shaped frame structure，Backgauge mechanical hand is made swing setting and is promoted by backgauge cylinder，Backgauge cylinder is arranged on alignment support，The charging side of backgauge mechanical hand is provided with sinciput material roller，Sinciput material roller can carry out the manual regulation of left and right directions，The discharging side of backgauge mechanical hand is provided with rear liftout roller，Rear liftout roller is made up and down setting and is promoted by material ejection cylinder，Bridging axle is parallel to upper and lower traction wheel and arranges，The discharging side of horizontal alignment wheels is provided with cutting machine parts，Cutting machine parts fixedly mount on alignment support.
After using technique scheme, wire rod alignment feature uses mechanical hand to adjust, metal wire rod more preferable alignment effect can be realized, reason is that biscuit is articulated in vertical placement on bridging axle, so metal wire rod is circumference bending in vertical plane, and be generally flat in horizontal plane, then make metal wire rod center basically identical with the centre of pull of upper and lower traction wheel by the action of backgauge mechanical hand, add holding tightly of before and after's liftout pair of rollers metal wire rod, metal wire rod is enable to be introduced between upper and lower traction wheel with stable attitude, the metal wire rod of leading-in end is substantially at relatively straightened condition；Then, first carried out the alignment of vertical direction by the traction metal wire rod of upper and lower traction wheel, carry out the alignment of horizontal direction the most again, more preferable alignment effect can be reached.Further, arranging of cutting machine parts can conveniently be cut off by stub bar irregular to metal wire rod at any time, it is to avoid the destruction that waste product produces and causes cold upsetting die of car.
As preferably, bridging axle is made up of two, left and right roller, the rear end thereof of two rollers in left and right is located on alignment support, the front end of two rollers in left and right rotates to be located on fixed supported slab, fixed supported slab is fixing with alignment support to be connected, the rear axle head of two rollers in left and right connects sprocket wheel respectively, and sprocket wheel is in transmission connection with the output of reducing motor, and fixed supported slab is provided with outer material blocking rod.By above-mentioned design, the blowing that can make metal wire rod biscuit is more smooth and easy.
