Welding point pre-preparation process as shown in Figure 1, promptly comprise and flatten station 105, bending station 106, a compacting station 107 of threading, the operating principle of described each station 105,106 and 107 working ends is identical with the operating principle of common press, basically all comprise upper and lower working end, the operation principle of each working end operation principle with pressure mould (as flattening station 105), hemming die (as bending station 106) and pressure mould (as thread silk and compacting station 107) respectively is identical; The action of welding post 108 is identical with the ordinary fixed mash welder with operation principle.When the welding equipment of electric detonator priming device bridge silk of the present invention was worked, the last working end of each station except that doubling station 111 all moved up and down, and following working end all maintains static; The power of each working end motion is all from the hydraulic cylinder to the lever opposite side of its application of force.In above-mentioned multistation, the technological effect of bending station 106 has the greatest impact to the welding point final mass.We know according to the metal forming principle, and the repeatedly moulding of gradual change is than one-time formed good stability, and the welding equipment of electric detonator priming device bridge silk of the present invention has adopted repeatedly forming technique when implementing, and its process is 90 ° →＜90 ° → 35 ° → compacting of folding.In addition, different because of the extension elongation of original workpiece pin silk, before the bending of pin silk, increased the unnecessary pin silk station of excision, the length unanimity that the preceding pin silk of bending is stretched out is so that follow-up pin silk is shaped.In order further to increase work efficiency, fracture of wire station 109, bridge wire resistance resistance are detected operations such as station 110, doubling station 111 and defective location of workpiece demonstration and all are included in the follow-up station of welding equipment of the present invention, thus in the welding equipment of the present invention multistation can also be refined as further that flattenings, pin silk are cut off, 90 ° of foldings, school type, 35 ° of foldings, the silk and compacting, welding, unnecessary bridge silk are removed, bridge wire resistance detects and stations compositions such as doubling of threading.
Fig. 2-1 and Fig. 2-2 shows the structure of flattening station 105 working ends of being adopted in the welding equipment of electric detonator priming device bridge silk of the present invention, and its working end is the rigidity working end.The purpose of flattening is the line contact condition after the some contact condition with former circular section becomes flattening, for follow-up welding creates conditions.Add man-hour workpiece 200 pin silk and place between seaming chuck 201 and the following chopping block 202, the pin silk is flattened by seaming chuck 201 downward squeezing actions.The length that the pin silk flattens preferably makes the pin filament length degree that turns back after the welding still be within the flattening scope of the pin silk that do not turn back.
The structural principle of pin silk cut-out station and process principle are with common shearing machine.Fixing following working end keeps the processing acute angle when making, with this following cutting edge as cutting knife, smooth to guarantee otch.Last working end is the combination of compensating squeeze head and cutting knife, should make the elastic working end and the working surface of following working end fit tightly the working depth of the working depth of compensating squeeze head＜cutting knife cutting edge during assembling; During work, compensating squeeze head touches with the pin wire connection earlier, and progressively compresses the pin silk along with its downward displacement increase; Compensating squeeze head continues to move downward, and cutting knife and pin wire connection are touched and the pin silk is cut off.
The final result of finishing the welding point pre-preparation on the pin silk is that the fold back portion of pin silk is rolled over 180 °, the fold back portion of pin silk and the overlap joint effect of fold back portion not when guaranteeing compacting, bending rear foot silk fold back portion is answered＜90 ° with the angle between the fold back portion not.Principle with compound die obtains this technological effect easily, but the mould structure complexity, difficulty of processing is big and the life-span is low, the bending station 106 working end structures among the present invention adopt shown in Fig. 3-1, Fig. 3-2 and Fig. 3-3 have certain interior angle, movement locus is the seaming chuck 301 of straight line and the technological effect that straight-line bending push pedal 302 realizes expection.The plane of movement of bending head is parallel with seaming chuck 301 plane of movement, the thickness of the distance on two planes 〉=pin silk dogleg section.Seaming chuck 301 is a compensating squeeze head, during work after seaming chuck 301 and following chopping block 303 compress workpiece 200, along with seaming chuck 301 continues to move downward, by leverage with bending push pedal 302 jack-up, with workpiece 200 bendings; After the process finishing, bending push pedal 302 playback earlier resets behind the seaming chuck 301.The method that seaming chuck 301 interior angles are determined is: after material category is determined, the theoretical value of dogleg section elastic recoil and pin silk flatten the counter-bending ability of part and all can utilize mechanics of materials formula to try to achieve as calculated, when the interior angle of seaming chuck 301 processing can be taken out on mould according to the dogleg section end,, the frictional force of strain and die surface and pin silk draw as calculated because of flattening crooked drag partly.Consider from improving the turn back angle of effect stability of pin silk, adopt substep bending method to carry out the Bending Processing of pin silk during the invention process, that is: four steps such as 90 ° of foldings, school shape, 35 ° of foldings and compacting.
The structure of compacting station 107 of threading that Fig. 4-1, Fig. 4-2 and 4-3 show among the present invention to be adopted.The action of this station comprises thread silk and compacting two parts.Wired and the elater principle of a mechanism and sewing machine of threading is identical, uses element also directly to take from element on the sewing machine, and the difference part only is to limit on the layout more compact because of structure space.Because of dogleg section in workpiece 200 transmission courses upwards, dogleg section produces with a pin of threading and interferes in workpiece 200 transmission courses, can be by the thread auxiliary movement of a pin of each class methods increase such as mechanical, electronic or pneumatic.The present invention adopts lever principle to realize this action request.Its operation principle is: during workpiece 200 transmission, the pin 403 of threading is still in that original position is motionless, and bridge silk 100 is in the inner top side of pin silk knuckle, is state to be threaded; After workpiece 200 put in place, seaming chuck 401 moved downward in the process, by leverage, and a pin 403 swings of threading, and preferential swing puts in place before seaming chuck 401 puts in place, makes bridge silk 100 place the root position of pin silk knuckle.System for compacting is the reproduction of flattening station, and difference only is the face width difference.
