The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the present invention, is not limited to the present invention.
As shown in Figure 2,3, extruder of the present invention comprises main device 10 and the main filling device 20 of cutting more than pressing cut.Master cuts device 10 and comprises two fixed support 11He shear blade travel mechanisms 12.Shear blade travel mechanism 12 is arranged between two fixed supports 11, shear blade travel mechanism 12 comprises main shear blade 121 and moving slider 122, as shown in Figure 6, main shear blade 121 is fixed on moving slider 122 by 5 screws on it via bolt, along with moving slider 122 moves up and down, shear to press remaining (this structure similarly to the prior art, therefore again do not repeat).As shown in Figure 6,7, when main shear blade 121, shear to press and Yu 30 time, this side of compression tool 40(that one side has extruded product near inside is positive S1), opposite side is near pressing remaining (this side is back side S2), the blade of main shear blade 121 drops to and presses 30 the lower end of Yuing from A, be B place, thereby will press cotangent to remove.Back side S2 has arc area S3, and the middle part of part arc area S3 is recessed towards positive S1, forms holding part 123.In the present embodiment, holding part 123 is rectangle, and its center line overlaps with main shear blade 121 center lines.
As shown in Figure 2,3, filling device 20 is a kind of bar linkage structure, and it comprises mobile tracking mechanism 21, lever body 22 and rotating mechanism 23.
Mobile tracking mechanism 21 comprises lead 211 and sleeve 212.The outside of one fixed support 11 is provided with the first guide holder 111, and it has the first pilot hole H1, and the lower end of lead 211 is through the first pilot hole H1, and lower end stretches in sleeve 212, and is fixedly connected with sleeve 212 by bolt.As shown in Figure 4, preferred, the cross section of lead 211 is roughly semicircle, and the through hole of the first pilot hole H1, sleeve 212 (not indicating) is consistent with the cross sectional shape of lead 211, avoids lead 211 to rock in the first guide holder 111, sleeve 212.
Lever body 22 comprises: one end of mounting rod 221, oil cylinder 222, first connecting rod 224, joint 223,225,227 and second connecting rod 226 mounting rods 221 is fixedly connected with lead 211, and the other end is fixedly connected with the cylinder body of oil cylinder 222.The plunger of oil cylinder 222 is fixedly connected with one end of joint 223, thereby joint 223 can be flexible with plunger under the driving of oil pressure.The other end of joint 223 is fixedly connected with one end of first connecting rod 224.The outside of the first guide holder 111 is fixed with the second guide holder 112, the second pilot hole H2 of its inside aligns with first connecting rod 224, first connecting rod 224 is sheathed in the second pilot hole H2, expose from the second pilot hole H2 below the lower end of first connecting rod 224, and be connected with joint 225 pivotables by bearing pin, the lower end of joint 225 is fixedly connected with the upper end of second connecting rod 226, and the lower end of second connecting rod 226 is fixedly connected with joint 227.By this lever body 22, when lead 211 moves, mounting rod 221 moves simultaneously, drives the first connecting rod 224 of below to move under the guide effect of the second guide holder 112.
As shown in Fig. 2,3,5, rotating mechanism 23 comprises: connecting plate 231, rotating shaft 232, fixed block 233 and material toggling shovel 234.One end of connecting plate 231 is connected with the lower end pivotable of joint 227 by bearing pin, and the other end of connecting plate 231 has through hole H3, and one end of rotating shaft 232 is positioned at through hole H3, and fixing by the key in through hole H3 and connecting plate 231.Fixed block 233 inside, offer through hole H4 along its length direction, and rotating shaft 232 is sheathed in through hole H4.The undersized of material toggling shovel 234 in or equal the size of holding part 123, material toggling shovel 234 is fixedly installed on rotating shaft 232, and exposes from the open trough of fixed block 233.In fixed block 233, in the sheathed sheath 235 in junction of material toggling shovel 234 and rotating shaft 232, when rotating shaft 232 and 234 rotation of material toggling shovel, reduce the friction with fixed block 233.As shown in Fig. 2,4,5, fixed block 233 is fixed on the below of moving slider 122 by a plurality of bolts 236, thereby when moving slider 122 moves, along with it moves.And, during assembling, first the first guide holder 111 is fixed on fixed support 11, lead 211 is stretched in the first guide holder 111, and lower end fixed muffle 212.Then, lever body 22 is connected in to mobile tracking mechanism 21.Again connecting plate 231 is connected with joint 227 pivotables, fixed block 233 is fixedly connected with moving slider 122.Finally the below of sleeve 212 is welded on fixed block 233.
Below, the shearing of extruder of the present invention, dnockout process are elaborated.
As shown in Figure 7, when main shear blade 121 is positioned at initial position A(, do not start to shear) time, material toggling shovel 234 is positioned at holding part 123, i.e. leftward position in Fig. 3.Shear blade travel mechanism moves down, and driven rotary mechanism 23 moves down, and the sleeve 212 of fixed block 233 welding moves down, and the sheathed lead 211 that is fixed on sleeve 212 in one end moves down, and by the first guide holder 111 guidings; The mounting rod 221 being connected with lead 211 moves down, and drives the first connecting rod 224 of below to move down, and by the second guide holder 112 guiding.Main shear blade 121 drops to final position B from initial position A, presses remaining the profile profile track along main shear blade 121 arc area S3 to be moved, and part is pressed and remainingly because conducting oneself with dignity, come off, and more than the larger metal crimp of viscosity, may stick in arc area S3.Now, keep shear blade travel mechanism invariant position, drive oil cylinder 222, plunger is stretched out, drive first connecting rod 224 to continue to move down, second connecting rod 226 moves down, and connecting plate 231 is rotated counterclockwise, and makes material toggling shovel 234 be rotated counterclockwise (as right positions in Fig. 3), in rotary course be deposited in part on arc area S3 and press to Yu and 30 contact, make to press Yu and 30 from main shear blade back side S2, peel off, and drop to the special-purpose remaining gathering-device of pressing, complete the main dnockout of cutting more than pressing.Subsequently, the plunger of oil cylinder 222 is retracted, drive material toggling shovel 234 to turn clockwise, get back in holding part 123, with shear blade travel mechanism 12, rise to initial position.
The material toggling pinch spalling of filling device of the present invention by rotation is from more than the pressure on main shear blade, dnockout action accurately, remaining contact area is large with pressing, effectively reduce the flow deformation of adherent metal, and the whole dnockout process of material toggling shovel is not interfered with other parts, particularly the targeting part of filling device is away from more than pressing, thereby avoids pressing remaining sticky glutinous with other parts, improves the stability of dnockout equipment.
It should be noted that in addition, each concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible combinations.
In addition, between various embodiment of the present invention, also can be combined, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
