The specific embodiment
As shown in Figure 1, the folded material of a kind of engaged element detection control apparatus comprises drive unit, and wire rod feed arrangement 1 cuts off drift 2, shaping mould 3, and moulding drift 4, spring bearer plate 10, near switch 9, and central controller; Drive unit is a wire rod feed arrangement 1, cuts off drift 2, and moulding drift 4 provides power; Wire rod feed arrangement 1 is positioned at and cuts off drift 2 belows, and the feeding that makes progress is used for the wire rod 11 of moulding engaged element; Cut off drift 2 and cut off said wire rod 11, and push to shaping mould 3 forward; Moulding drift 4 is positioned at shaping mould 3 tops, and cooperates with shaping mould 3, will be stamped into the engaged element of moulding through the wire rod that cuts off drift 2 cut-outs; Spring bearer plate 10 is positioned at the top of moulding drift 3, and to moulding drift 3 downward pressure is provided; Be positioned at the top of spring bearer plate 10 near switch 9, be used to detect under the situation of the folded material of engaged element, by the spring bearer plate 10 of jack-up; Central controller is used to receive the said control signal of sending near switch 9, and sends control signal to wire rod feed arrangement 1.
Wire rod feed arrangement 1 is sent the wire rod 11 of certain-length to operation interval with certain speed.Under the effect of cutting off drift 2, be cut off, and before be pushed in the shaping mould 3.Under the effect of moulding drift 4, the head of engaged element is rushed out shrinkage pool.Formed engaged element gets into next process, is implanted on the strap in situ, accomplishes a circulation.So circulation, per minute is about 1000 to 1500 times.
As illustrated in fig. 1 and 2, if a last engaged element 13 does not get into next process, implant strap.And new engaged element 14 has been pushed to shaping mould 3, then can appear at shaping mould 3 upper surfaces simultaneously because of two engaged elements, thereby the situation of folded material occurs.As shown in Figure 3, because of the upper surface at shaping mould 3 exists two engaged elements 13 and 14, then the second moulding drift 42 can produce a displacement that makes progress, and the distance of displacement is the height of engaged element 14.Thereby obtain a displacement signal.As shown in Figure 2, displacement signal can be detected near switch 9, and produces a signal of telecommunication, is sent to central controller.Central controller is judged as the generation of folding the material situation through computing, then can send one and control signal to drive unit and wire rod feed arrangement 1.When drive unit receives the stopping signal that central controller sends, then can quit work.But because effect of inertia is having under the situation of braking and will really stop, entire machine needs 1~2 do action of many actions.With this simultaneously, one of the extra transmission of central controller controls signal to wire rod feed arrangement 1, because the reaction speed of wire rod feed arrangement 1 is very fast, can realize stopping feeding at once.In such cases, complete machine is in the state of idle running, thereby has avoided the damage of related accessory.
As shown in Figure 1, be provided with percussion hammer 8, moulding drift holder 5, moulding drift 4.Under the effect of drive unit, percussion hammer 8 can move up and down, and drives moulding drift holder 5 and moulding drift 4 moves up and down.As shown in Figure 4, moulding drift holder 5 comprises base 51 that is connected with percussion hammer 8 and the fixation clip 52 that cooperates with base 51.Moulding drift 4 comprises the first moulding drift 41 and the second moulding drift 42.The first moulding drift 41 is used for the punching press engaged element, and the second moulding drift 42 is used for detecting the displacement that produces because of folded material and being used for separating engaged element from the first moulding drift 41, also promptly has the function that detects folded material and help discharging concurrently.
In order to reach the requirement of punching press, the first moulding drift 41 is fixed on the base 51 through holding screw, but the second moulding drift 42 being fixed on the moulding drift holder 5 through fixation clip 52 relative displacements.
As shown in Figure 6, the top of the second moulding drift 42 is provided with protuberance, is used to hang over moulding drift holder 5, makes that when moulding drift holder 5 moved upward, the second moulding drift 42 also can be followed and moved upward.When moulding drift holder 5 moved downward, the second moulding drift 42 moved downward under the effect of spring bearer plate 10 elastic pressures.In order to make the second moulding drift 42 have the function of discharging; Being provided with of the second moulding drift 42 can be grown a bit slightly; So that when punching press; The first moulding drift 41 is accomplished when on the wire rod that cuts off, going out shrinkage pool, and the second moulding drift has a certain amount of with respect to the first moulding drift 41 and the upwards displacement of direction of moulding drift holder 5.But this displacement is very small, also can not detected near switch 9, is mistaken for the generation of folded material situation; 41 punchings of the first moulding drift begin to top offset after accomplishing, and at this moment, the second moulding drift 42 is still being pressed the engaged element 13 of moulding, and the moulding drift 41 of winning can successfully be separated with engaged element 13, thereby realize the function of discharging.When the protuberance on the second moulding drift, 42 tops contacted with moulding drift holder 5, the second moulding drift 42 will be followed moulding drift holder 5 and moved up together, thereby had realized the process of one time punching molded and discharging.
As shown in Figure 1, between the top of the second moulding drift 42 and spring bearer plate 10, transmission thimble 6 is set, and is used to the transmission tailstock barrel 7 that transmission thimble 6 provides guide effect.Because the existence of transmission thimble 6, it is more reasonable near the layout of switch 9 to make that spring bearer plate 10 reaches.Simultaneously, transmission thimble 6 can also be at a distance, the displacement signal of the second moulding drift 42 is passed near switch 9, and can the power of spring bearer plate 10 be passed to the second moulding drift 42.Simultaneously, owing to there is transmission tailstock barrel 7, transmission thimble 6 can only move up and down in transmission tailstock barrel 7, thereby can eliminate second moulding drift 42 disturbance all around, the only motion of remaining above-below direction, and the transmission of exerting all one's strength is more steady.
An important function of spring bearer plate 10 is for transmission thimble 6 and the second moulding drift 42 a downward active force to be provided.Guarantee the accuracy of check result, also can power be provided simultaneously for the second moulding drift discharging and the material returned.
Shown in Figure 4 and 5, moulding drift holder comprises base 51 and fixation clip 52, and the middle part at base 51 is provided with cross recess, is used to hold and fixes the first moulding drift 41.The first moulding drift 41 is placed in the vertical cell body of cross recessed, limits the motion of its left and right directions; Laterally in the cell body ejector pin 53 is being set, the motion of restriction above-below direction; Be provided with holding screw 54 at the back side of base 51, limit the motion of the first moulding drift, 41 fore-and-aft directions forward.Through setting like this, the moulding drift 41 of winning is realized and being connected of moulding holder 5 no relative motions.
As shown in Figure 6, the top of the second moulding drift 42 is provided with protuberance, is used for cooperating with moulding drift holder, hangs on the moulding drift holder, makes that it can be when moulding drift holder moves upward, and it also can move upward.
