Specific embodiment
The utility model pressing equipment is described in further detail below in conjunction with specific embodiment and accompanying drawing.
As depicted in figs. 1 and 2, in a preferred embodiment, pressing equipment of the present utility model mainly includes pedestal 10 and consolidates
The lower mould 20 and support 30 being scheduled on pedestal 10, also including mold 40 and be fixed on support 30 for driving mold
40 drive mechanisms 50 for moving up and down.Wherein, drive mechanism 50 is linked by a transmission mechanism 60 with mold 40.Transmission mechanism
60 power that can be exported drive mechanism 50 become big rear output.
Wherein, support 30 is included the first top board 32 being fixed on pedestal 10 by column 31, is fixed on by column 33
Second top board 34 of the top of the first top board 32.Please also refer to Fig. 3, the lower surface of the second top board 34(I.e. towards the first top board 32
One side)A joint chair 342 is fixed with, on joint chair 342 axle is formed with.Drive mechanism 50 be pneumatic rotary actuator, its conduct of piston rod 51
Its drive end, the position that it stretches out with piston rod 51 is provided with ears ring 52 on opposite end.The ears ring 52 rotatably connects
It is connected on the axle of joint chair 342, so as to drive mechanism 50 is oscillatable about an axis.
It is formed with the position relative with drive mechanism 50 on first top board 32 and is available for piston rod 51 through simultaneously double swerve
Groove 321, piston rod 51 reaches the lower section of the first top board 32 through groove 321.
The lower surface of first top board 32 is fixed with a joint chair 322, and on joint chair 322 axle is formed with.Transmission mechanism 60 includes first
Connecting piece 61, L-type(Alternatively triangle)The second connecting piece 62, the 3rd connecting piece 63 and the 4th connecting piece 64.Wherein, first
Connecting piece 61 is fixedly connected on the end of piston rod 51 of drive mechanism 50.The first end of the second connecting piece 62(It is one of free
End, is then one of corner if triangle, referred to as the first corner)It is rotatably connected on the first connecting piece 61, it second
End(Another free end, is then another corner if triangle, referred to as the second corner)It is rotatably connected in joint chair
On 322, its turnover position(I.e. the bending part of L-type part, is then last corner, referred to as the third angle if triangle
Portion)It is rotatably connected to the 3rd connecting piece 63.3rd connecting piece 63 is yi word pattern part, and its one end is rotatably connected the second connection
Part 62, the other end is rotatably connected the 4th connecting piece 64.4th connecting piece 64 is fixedly connected lower mould 20.Wherein, it is above-mentioned can
Rotate connection to be on chain connection, i.e. a side and be provided with axle, and the opposing party be provided with can socked shaft hole.Additionally, above-mentioned can
The direction of rotation is respectively positioned on same plane or the plane being parallel to each other, and these planes are parallel or same with the rotatable direction of cylinder
One plane.The first end of the second connecting piece 62 is more than the length at its second end to position of transferring to the length at position of transferring, so as to
Constitute laborsaving lever.
At least two punching die frame guide pillars 11 are provided with pedestal 10, it is highly more than mold 40 and the height of lower mould 20
Degree summation, cannot depart from punching die frame guide pillar 11 in highest order and be advisable with mold 40, and on mold 40 and lower mould 20
The pilot hole for being available for punching die frame guide pillar 11 to pass through is each formed with, when up and down motion under driving of the mold 40 in drive mechanism 50
When, its all without departing from punching die frame guide pillar 11, so as to can ensure that machining precision.
At least two stripper guide pillars 12 are additionally provided with pedestal 10, are arranged between punching die frame guide pillar 11, height is slightly
It is short, it is advisable with the height summation slightly larger than mold 40 and lower mould 20, spring 13 is cased with thereon.Spring 13 plays punching press buffering
With the effect for helping the demoulding of mold 40.
In work, when the piston rod 51 of drive mechanism 50 is from its lowest order(As shown in figure 3, being also now mold 40
Lowest order)When moving upwards, the first end of the second connecting piece 62 has been pulled upwardly, and its second end rotates around the axle of joint chair 322, its
Turnover position upper direction to the right, drives relative second top board 34 of drive mechanism 50 to incline to the right, and the 3rd connecting piece 63 is by the
The turning point bit strip of two connecting pieces 62 moves upper direction to the right(Now the 3rd connecting piece 63 is inclined to the right), so as to mold
40 are pulled up, as shown in Figure 4.When the piston rod 51 of drive mechanism 50 is moved upwards from its highest order, the second connecting piece
62 first end is pressed downward, and its second end rotates around the axle of joint chair 322, and its turnover position is just moved to left down, is driven and is driven
The piston rod 51 of mechanism 50 to upright position is recovered, and the 3rd connecting piece 63 is pressed to the left by the turnover position of the second connecting piece 62
Moved beneath(Now the 3rd connecting piece 63 also recovers to upright position), so as to mold 40 is moved downward.
Thus, pressing equipment make use of laborsaving lever principle using the transmission mechanism of simple structure, drive mechanism is exported
Power become big after-applied to on converted products, such that it is able to process while soft material, hard material can also be processed.
Although carrying out with reference to embodiments above to description of the present utility model, it is familiar with the art
Personnel can carry out many replacements, modifications and variations, be obvious according to above-mentioned content.Therefore, it is all such
Substitute, improve and change and be included in the spirit and scope of appended claims.
