Description
Technical field
The present invention relates to the liftout attachment after a kind of rubber tyre moulding, especially a kind of tire forming vulcanizer pushes away device of tyre, belongs to vulcanization of rubber machinery technical field.
Background technology
Two-mold tire shaping and curing press needs tire to eject bed die after tyre vulcanization completes.Retrieval finds that (seeing that application number is 201020113201.X, 201120140189.6 Chinese patent literatures) prior art and conventional ejecting mechanism all adopt jacking cylinder and so on device directly to eject from bottom to top.During practical operation, wish that top lift reduces gradually, jacking speed from fast to slow, this is that direct jacking is difficult to realize.And the limited two-mold tire shaping and curing press of oneself height is often difficult to settle jacking apparatus in frame bottom.
Summary of the invention
Primary and foremost purpose of the present invention is: with simple structure realize that top lift reduces gradually, jacking speed pushes away device of tyre by fast gradually slow tire forming vulcanizer.
Further aim of the present invention is: propose a kind of junction of can avoiding and be out of shape, get loose, thereby avoid tire to occur that the tire forming vulcanizer of overlap pushes away device of tyre.
In order to reach above-mentioned primary and foremost purpose, tire forming vulcanizer of the present invention pushes away device of tyre and comprises that table top upper support has the frame of the bed die of central hole, described frame and top can form vertical moving sets through the push rod of described perforation, the hinged-support of the fixing hinged lever in column middle part of described frame one side, the outer end of described lever and the overhanging end of hydraulic cylinder piston rod are hinged, described hydraulic cylinder is contained in the lower surface of described table top away from one end hinge of piston rod, the lower end of described push rod has horizontal direction chute, the inner of described lever is the globular model that is contained in the moving cooperation of formation in described chute, when the piston rod of described hydraulic cylinder is during in retraction extreme position, the axis of described piston rod is perpendicular to the line at the hinged center in the hinged center of described lever and lever outer end.
Like this, when making piston rod, hydraulic cylinder pressurization started when overhanging by the extreme position of retracting, the power arm of lever is the longest, momentary angular speed is also maximum, along with the increasing of lever out reach, the angle of the hinged line of centres in the hinged center of piston rod axis and lever to lever outer end diminishes gradually, and the power arm of lever reduces thereupon, momentary angular speed also reduces thereupon, thus with simple winding machine the top lift of push rod reduce gradually, jacking speed is by gradually slow soon.And after employing the present invention, owing to by lever, the motion that presses down hydraulic cylinder being converted to jacking campaign, so bracket height can suitably reduce, and jacking apparatus can be arranged on vulcanizer easily.
The present invention further improves, on the extended line of the round end center of described lever the inner in described line (with the hinged center of the hinged center of lever and lever outer end and piston rod overhanging end on same straight line), when described push rod (piston rod of corresponding described hydraulic cylinder is in overhanging, retraction extreme position) is during respectively in Upper-lower Limit position, described extended line is about horizontal line symmetrical (be respectively with horizontal line ± (25 °-35 °) angle is advisable).Like this, can make the relative displacement of horizontal direction between lever and push rod minimum, be conducive to guarantee the stability of jacking campaign.
In order to reach further object, described hinged-support is by forming with the bearing being fixedly connected with described base with the base of described column one side welding, and protrude at the middle part, vertical surface of described base, and described bearing has the concave face matching with described vertical surface.Like this, after both are fixedly connected with each other, shear force huge in the time of can making jacking campaign is born by base and bearing self structure, and no longer as prior art, act directly on securing member, thereby effectively avoided junction distortion, get loose, and then avoided tire to occur overlap.
In a word, the present invention is simple in structure, designs ingeniously, is easy to processing and installs, with low cost, can avoid tire overlap even to scrap, and is conducive to guarantee tire quality and tire production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the hinged-support structural representation of Fig. 1 embodiment.
The specific embodiment
Embodiment
The present embodiment tire forming vulcanizer pushes away device of tyre basic structure as shown in Figure 1, comprises that table top upper support has the frame 1 of the bed die 10 of central hole, places chuck 9 in the perforation of bed die 10.Frame 1 can form vertical moving sets through the push rod 8 of perforation with top.The hinged- support 2,3 of the fixing hinged lever 6 in column middle part of frame 10 1 sides, outer section of 6-1 termination of lever and the overhanging end of hydraulic cylinder 7 piston rods are hinged, hydraulic cylinder 7 is contained in the lower surface of table top away from one end hinge of piston rod, the lower end of push rod 8 has horizontal direction chute, and the inner segment 6-2 termination of lever 6 is and the moving globular model coordinating of chute.On the extended line of the line of this round end center in the hinged center in the hinged center of lever and lever outer end, the hinged center of this round end center and the hinged center of lever and lever outer end and piston rod overhanging end is on same straight line.When the piston rod of hydraulic cylinder 7 is during in retraction extreme position, the axis of piston rod is perpendicular to the line at the hinged center in the hinged center of lever 6 and lever outer end.When the piston rod of the corresponding hydraulic cylinder 7 of push rod 8 is during in overhanging, retraction extreme position and respectively in Upper-lower Limit position, above-mentioned extended line is symmetrical about horizontal line, is respectively ± 30 ° of angles with horizontal line.
In addition,, referring to Fig. 2, hinged-support consists of with the bearing 3 being fixedly connected with by leveling screw 4 with base 2 base 2 of frame 1 column one side welding.On bearing 3, there is hinged hole 3-2.The middle part, vertical surface of base 2 has rectangle and protrudes 2-1, and bearing 3 has with rectangle and protrudes the rectangular depression 3-1 matching with the corresponding mask of vertical table face.Particularly, lever 6 is hinged through plain bolt 6-3 and bearing 3, and hinged hole 3-2 is the common screw matching with bolt 6-3.
While pushing away tire, hydraulic cylinder 7 activation lever 6, eject lower chuck 9, thereby tire are released to bed die 10.Because piston rod starts when overhanging, the power arm of lever is the longest, momentary angular speed is also maximum, increasing along with lever out reach, the angle of the hinged line of centres in the hinged center of piston rod axis and lever to lever outer end diminishes gradually, the power arm of lever reduces thereupon, and momentary angular speed also reduces thereupon, thereby has realized that required top lift reduces gradually, jacking speed is by gradually slow soon.Meanwhile, because hydraulic cylinder 7 is inverted, can be by the deadweight activation lever 6 of piston rod when pushing away tire, thus reduce power consumption.
In pushing away tire process, the shear force that 7 pairs of hinged places of hydraulic cylinder produce is born by base and bearing self structure, can not make securing member be out of shape, get loose, rupture, thereby effectively prevent the tire overlap that lower chuck drifts about up and down and causes, the tire of having avoided mechanical breakdown to cause is scrapped.
The apparatus structure of the present embodiment is simple, designs ingeniously, can avoid tire overlap even to scrap, and is conducive to guarantee tire quality and tire production efficiency.
