Introduce the utility model below in conjunction with concrete the use: corresponding each mould of whole processing can be divided into following station: station to be punched, for the first time the jumping-up station, for the second time the jumping-up station, eject station, flatten station, blanking station and delivery cover station.

At first respectively put a core rod die sleeve from station to be punched to blanking mechanism on 9, totally 6, the core rod die sleeve clamping that is positioned on the station 4 to be punched compresses pin 11 blanks, other stations are not put, place 1 core rod die sleeve for the treatment of into mould at feedboard 12-1 then, convenient wheel changes, be equipped with equally in it and compress pin 11, because the taking-up float plate 10-5 in the delivery cover mechanism 10 is in float state, just in time withstand the core rod die sleeve of placing on the blanking mechanism 9, whole like this station just is in stable state, i.e. state to be processed.

Station 4 to be punched: when the downward punching press of patrix 1, wedge 3-5 inserts the wedge mouth 3-6 on the push pedal 3-1, be against on the bearing 3-7, take advantage of a situation push pedal 3-1 is moved to left, and then make the core rod die sleeve on the push pedal 3-1 fall into station 4 to be punched, while is owing to patrix 1 being pressed into, make the taking-up float plate 10-5 in the delivery cover mechanism 10 press down, because handle 10-9 is positioned on the arm perpendicular to die shoe 2-1 of L shaped groove 10-13, after taking-up float plate 10-5 presses down, the effect of torsion spring 10-8 makes handle 10-9 rotate, snap on the horizontal arm of L shaped groove 10-13, then patrix 1 lifts, push pedal 3-1 will move to right, at this moment the core rod die sleeve on the blanking mechanism 9 is being pushed under the effect that push pedal 3-1 moves to right in the delivery cover mechanism 10, the core rod die sleeve that is positioned at station 4 to be punched is then pushed the first jumping-up station by push pedal 3-1, in order to take out the core rod die sleeve on the delivery cover station, pull handle 10-9 to the upright arm of L shaped groove 10-13, at this moment taking out float plate 10-5 floats once more, the side that takes out float plate 10-5 blocks the core rod die sleeve that is positioned on the blanking mechanism 9, so just remain on stable state again, wait for that patrix 1 next time presses down, and the core rod die sleeve can take off smoothly and places on the feedboard 12-1 again, in the follow-up station taking-up of core rod die sleeve with deposit all identically, the back repeats no more;

Jumping-up station for the first time: when the downward punching press of patrix 1, the first patrix briquetting 5-1 is pressed on the core rod group 15, the first jumping-up bar 5-3 is pressed in and compresses on the pin 11, compress pin 11 heads and enter first one-step forming in the first jumping-up chamber 5-4, and die sleeve 16 is pressed on the elasticity jacking block 18, cause elasticity jacking block 18 to press down, and then the rubber ring 17-2 on the elasticity of compression return unit 17, with the deposit elastic potential energy, after patrix 1 lifts, rubber ring 17-2 elastic potential energy discharges, jack-up elasticity jacking block 18, and then jack-up core rod die sleeve, taking advantage of a situation just will compress pin 11 and take out of in the chamber, so far finish jumping-up processing for the first time, same with reference to the movement of above-mentioned core rod die sleeve on station, under the effect that push pedal 3-1 moves to right, enter the second jumping-up station through the core rod die sleeve after the jumping-up processing for the first time, on feedboard 12-1, constantly replenish the core rod die sleeve that takes off from delivery cover mechanism 10 in addition, make whole progressive die wheel change seamless connection;

When patrix 1 backhaul, the core rod die sleeve of jumping-up station moves to jumping-up station for the second time for the first time;

Jumping-up station for the second time: when the downward punching press of patrix 1, the second patrix briquetting 6-1 is pressed on the core rod group 15, the second jumping-up bar 6-3 is pressed in and compresses on the pin 11, compress pin 11 heads and enter first one-step forming in the second jumping-up chamber 6-4, and die sleeve 16 is pressed on the elasticity jacking block 18, cause elasticity jacking block 18 to press down, and then the rubber ring 17-2 on the elasticity of compression return unit 17, with the deposit elastic potential energy, after patrix 1 lifts, rubber ring 17-2 elastic potential energy discharges, jack-up elasticity jacking block 18, and then jack-up core rod die sleeve, taking advantage of a situation just will compress pin 11 and take out of in the chamber, so far finish jumping-up processing for the second time, same with reference to the movement of above-mentioned core rod die sleeve on station, core rod die sleeve after the process jumping-up processing for the second time enters under the effect that push pedal 3-1 moves to right and ejects station, constantly replenishes from delivery on feedboard 12-1 in addition and overlaps the core rod die sleeve that mechanism 10 takes off, and makes whole progressive die wheel change seamless connection;

When patrix 1 made progress backhaul, the core rod die sleeve of the second jumping-up station moved to and ejects station;

Eject station: when the downward punching press of patrix 1, owing to be the jacking block 7-7 of ejecting mechanism 7 under the core rod group 15, thereby maintain static, the push rod 7-5 that ejects on the patrix withstands on the die sleeve 16, and die sleeve 16 belows are unsteady ejection block 7-8, and therefore this unsteady ejection block 7-8 presses down, and at this moment die sleeve 16 will stagger with core rod group 15, compress pin 11 this moment and just can under the effect of the first knock-pin 7-4, move down a bit ofly, make things convenient for follow-up flattening moulding;

When patrix 1 made progress backhaul, the core rod die sleeve that ejects station moved to the flattening station;

Flatten station: when the downward punching press of patrix 1, among the guide pillar hole 8-7 on the guide pillar 8-6 insertion die shoe 2-1 on the upper bolster 1-1, the second knock-pin 8-3 withstands and compresses pin 11, because guide pillar 8-6 is designed to wedge structure, guide pillar 8-6 presses down, and makes two to flatten slide block 8-10 move toward one another, will compress pin 11 heads and flatten moulding, when patrix 1 made progress backhaul, the core rod die sleeve that flattens on the station moved to the blanking station;

Blanking station: when the downward punching press of patrix 1, because the effect of patrix 1, material blanking tube 9-12 on the blanking mechanism 9 separates core rod group 15 and die sleeve 16 earlier in advance in advance, convenient follow-up action, depression bar 9-5 is pressed in die sleeve 16 is sunk then, two push rod 9-11 insert among the jack 15-3 of each core rod 15-1, the gradient of push rod 9-11 is identical with the gradient of jack 15-3, die sleeve 16 sinks like this, and core rod group 15 is motionless, has just reached the purpose that the die sleeve core rod staggers, relend the effect that helps blanking bar 9-3, the pin 11 that compresses that processes is ejected from material blanking tube 9-12, drop out by the second material-dropping hole 9-8, the processing that so far compresses pin 11 has just all been finished;

When patrix 1 again upwards during backhaul, the core rod die sleeve that does not have material moves to delivery cover station, and following the example of of core rod die sleeve above-mentionedly explained, repeats no more.

Repeat aforesaid operations, a plurality of pins 11 that compress of processing that can be continuous, than prior art, its efficient improves greatly, has also filled up the blank that compresses the continuous machine-shaping of pin.

Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
