Description
Technical field
The invention relates to a kind of clamping apparatus of Jet forming machine, refer in particular to and a kind ofly can be located at transmission mechanism in the body by group and drive the action of elbow connection rod group, pass the clamping apparatus of movable die holder, reach the purpose of saving installing space.
Background technology
Consult shown in Figure 6, take a broad view of the locked mode and the die sinking action of general Jet forming machine, undertaken by clamping apparatus mostly, and general common toggle formula Jet forming machine as shown in Figure 6, be to stretch out extra-organismal oil hydraulic cylinder 20 with its elbow connection rod group 10 cooperations to pass movable die holder 30 action displacements, and open, the stroke of locked mode, its major defect is:
Above-mentioned common toggle formula Jet forming machine because oil hydraulic cylinder 20 must stretch out in the outer long distance of body, therefore, is cased and when transporting, must be used bigger volumetric spaces, and the cost that increases packing and transport; Simultaneously, when Jet forming machine was installed, oil hydraulic cylinder can take in the factory building utilized area partly, and made the configuration of site planning and Jet forming machine factory building in produce great the puzzlement.
Consult Fig. 7-shown in Figure 9, for improving above-mentioned traditional toggle formula Jet forming machine shortcoming in the use.The dealer develops a kind of italian patent case, its application number is 92830069.8 (notification number is 0511170A2), its main result is, its elbow connection rod group 2 is that group is located at 1 of movable die holder 5 and tray, the first elbow arm 21 of this elbow connection rod group 2 is articulated on the inwall of tray 1, and articulate the second elbow arm 22, and two ends articulate with the first elbow arm 21 and armite 24 respectively on the second elbow arm 22, and after the last two ends of the second elbow arm 22 articulate with the first elbow arm 21 and armite 24 respectively, appropriate location on this second elbow arm 22, can articulate for a end with the 3rd elbow arm 23, the end in addition of the 3rd elbow arm 23 then is pivoted with continous action base 3, can make two oil hydraulic cylinders 4 be fixedly arranged on the both sides of continous action base 3 respectively, as shown in Figure 9, the movable end of the force-output shaft 41 of oil hydraulic cylinder 4 then can be fixedly arranged on the movable die holder 5; In carrying out locked mode when action, firm except still having with the mould locking, the oil hydraulic cylinder 4 that pushes elbow connection rod group 2 must not stretched out outside the body, save packing and shipment and delivery cost and reach, and reduce the installing space purpose.Its major defect is:
Yet, the foregoing invention patent is when actual production and use, though can reach predetermined purpose and effect smoothly, but because its oil hydraulic cylinder that pushes movable die holder is the both sides that are arranged at continous action base, thereby need use two oil hydraulic cylinders, can drive the action of elbow connection rod group and movable die holder stably, and manufacturing cost can't be reduced.

The specific embodiment
Consult Fig. 1-shown in Figure 3, the tray 1 of Jet forming machine of the present invention and movable 5 of the die holders elbow connection rod group 2 that is pivoted, and movable sleeve is provided with a continous action base 3 on the tie-rod 40 of 5 of tray 1 and movable die holders, and the first elbow arm 21 of elbow connection rod group 2 is hubbed on the inwall of tray 1, and articulate the second elbow arm 22, and two ends articulate with the first elbow arm 21 and armite 24 respectively on the second elbow arm 22, and after two ends articulate with the first elbow arm 21 and armite 24 respectively on the second elbow arm 22, on the second elbow arm 22, articulate for a end with the 3rd elbow arm 23, simultaneously, the end in addition of the 3rd elbow arm 23 then is pivoted with continous action base 3, and its main improvement is:
Group is provided with a transmission mechanism 7 on this continous action base 3, and transmission mechanism 7 cooperates a ball screw 72 to be formed by power source 71; This power source 71 can drive the swivel nut 32 that is mounted on continous action base 3 central authorities by link component 711 and rotate, and being spiral shells, ball screw 72 is located in the swivel nut 32 of continous action base 3, and the front end of ball screw 72 is sheathed to be fixed in the joint 51 of movable die holder 5 dorsal parts, links affixed with movable die holder 5; In addition, be provided with a mesopore 11, stretch into for ball screw 71 in the central authorities of tray 1.
The present invention implements in action, and when stretching out locked mode, can make the power source 71 of driver 7 drive swivel nut 32 rotations, and swivel nut 32 spiral shell on ball screw 72 is advanced, and then drive continous action base 3 is passed forward, and the movable die holder 5 of interlock advances along tie-rod 40, at this moment, movable die holder 5 also connects drive armite 24 makes the second elbow arm, 22 outer opening, and stretch out forward, and the second elbow arm 22 drives the 3rd elbow arm 23 again toward interior passing, simultaneously, passing by the 3rd elbow arm 23, continous action base 3 also continue to be moved advance, and near the finality of locked mode stroke the time, the magnifying power that elbow connection rod group 2 is exerted oneself power source 71 is amplified to maximum, and produce great clamp force, with mould locking [as shown in Figure 2].
Otherwise, when desiring die sinking in action enforcement, can make power source 71 counter-rotatings of transmission mechanism 7, and make the swivel nut 32 of continous action base 3 on ball screw 72, retreat, and then but drive revolving die seat 5 retreats along tie-rod 40, and movable die holder 5 also drives armite 24, the second elbow arm 22 is passed backward, this second elbow arm 22 also drives the 3rd elbow arm 23 and passes backward, and continous action base 3 is retreated, and the also passing backward of the first elbow arm 21, and when elbow connection rod group 2 is got back to bottom dead centre, promptly drive movable die holder 5 and retreat, and finish opening stroke (as shown in Figure 3) to the location.
Embodiment 2
Consult Fig. 4-shown in Figure 5, the transmission mechanism of the drive elbow connection rod group 2 of embodiments of the invention 2 and 5 actions of movable die holder is one group of oil hydraulic cylinder 73 that is located at continous action base 3 centre, the force-output shaft 731 of this oil hydraulic cylinder 73 is held the dorsal part that is fixed in movable die holder 5 in addition, and when the force-output shaft 731 of oil hydraulic cylinder 73 stretches out forward, interlock elbow connection rod group 2 and movable die holder 5 move, and carry out the stroke of locked mode; And when the force-output shaft 731 of oil hydraulic cylinder 73 is regained, the stroke (as shown in Figure 5) that carries out die sinking.
By above element form and the action implementation as can be known, the present invention removes still can be with on the continous action base that is installed in order to the transmission mechanism that drives the action of elbow connection rod group and movable die holder in the body, and open, outside the stroke of locked mode, transmission mechanism of the present invention only is one group of power source, cooperation swivel nut and ball screw also can drive toggle mechanism and movable die holder is locked, the action of die sinking, therefore has the characteristics of saving assembling space and packing shipment and delivery cost; Simultaneously, can only use single oil hydraulic cylinder can drive that toggle mechanism is locked with movable die holder, the action of die sinking, therefore have more the advantage of simplifying member and reducing manufacturing cost, thereby have the usability on the industry.
