The upper ends of the pressing rods 4 extend to the upper part of the fixed seat 3, and the lengths of the pressing rods 4 extending to the upper part of the fixed seat 3 are arranged in a stepped manner.
The lower extreme of depression bar 4 extends to fixing base 3 below, and flexible cylinder 7 is installed to the depression bar 4 lower extreme under extending to fixing base 3 below, and the piston rod and the depression bar 4 fixed connection of flexible cylinder 7, the cylinder body fixed mounting of flexible cylinder 7 is in frame 12, and the purpose of so setting is: the reset of the pressing rod 4 is realized through the telescopic cylinder 7.
The mounting groove 8 sets up on extending to the depression bar 4 of fixing base 3 below, has seted up the groove of stepping down on the fixing base 3 that the mounting groove 8 corresponds, and the mounting groove 8 cross-section is semicircle arc, and mounting groove 8 movable mounting has rotatory piece A5, and rotatory piece A5's tangent plane part extends to the mounting groove 8 outside, and the whole length of mounting groove 8 is greater than the length of rotatory piece, and the purpose of so setting is: when the movable die 1 is in rotary cutting motion, the rotary block A5 can slide axially in the mounting groove 8, and the axial displacement compensation function is achieved.
And a limiting plate 14 is fixedly arranged on the fixed seat 3 corresponding to the outer side of each rotating block B9, and the limiting plate 14 is used for limiting the rotating block B9 and preventing the problem that the rotating block B9 excessively slides axially in the mounting groove 8 and is separated from the mounting groove 8.
The movable die base 2 corresponding to each vertical power conversion mechanism is respectively provided with a horizontal power conversion mechanism, the horizontal power conversion mechanism is composed of a mounting groove 8 arranged on the movable die base 2 and a rotating block B9 movably mounted in the mounting groove 8, the mounting groove 8 on the movable die base 2 is identical to the mounting groove 8 on the lower pressure rod 4 in structure, the rotating block B9 is identical to the rotating block A5 in structure, the section of the rotating block B9 is circular, one side of the rotating block B9 is a tangent plane, the rotating block B9 is movably mounted in the mounting groove 8 on the movable die base 2, the tangent plane part of the rotating block B9 extends to the outer side of the mounting groove 8, and the purpose of the arrangement is that: the two tangential surfaces of the convenient rotating block A5 and the rotating block B9 are contacted with each other, thereby realizing power transmission.
When the rotary die is used, the lower pressure rod 4 drives the rotary block A5 to move downwards, and the rotary block A5 and the rotary block B9 are in contact connection, so that the rotary block B9 synchronously rotates under the action of the pressure of the rotary block A5 after the rotary block B9 is acted by the pressure of the rotary block A5, and in the process, the rotary forces of the rotary block A5 and the rotary block B9 are converted into horizontal thrust of the movable die 1 to push the movable die base 2 to move horizontally in a cross shape.
The vertical power conversion mechanism and the horizontal power conversion machine are in surface contact through the tangential surfaces of the rotating blocks A5 and B9, and under the action of vertical power, the rotating blocks A5 and B9 rotate within the range of 0-50 degrees.
The transmission device for the horizontal shearing movable die specifically acts as follows:
Because the four corners of the movable die base 2 are respectively provided with the fixed seats 3, each fixed seat 3 is respectively provided with two longitudinal sliding holes 6, and the lower pressure rods 4 are slidably arranged in each longitudinal sliding hole 6, the width faces of the two lower pressure rods 4 which are arranged on the same side and in the same direction of the movable die 1 are opposite to each other to form the same power group, the lengths of the lower pressure rods 4 which extend to the upper part of the fixed seat 3 of the same power group are the same, the lengths of the lower pressure rods 4 which extend to the upper part of the fixed seat 3 of different power groups are different, and the lengths of the lower pressure rods 4 which extend to the upper part of the fixed seat 3 of each power group are sequentially arranged step by step, so that the power groups sequentially and orderly reciprocate under the lower pressure of the fixed die 11.
In summary, according to the arrangement of the fixing bases 3 on the movable mold base 2, two pressing rods 4 in the same direction of the two fixing bases 3 on the same side are the same power group (see fig. 4. In order to distinguish each power group, the filling patterns of eight pressing rods 4 at four corners of the movable mold base 2 are divided, so that the pressing rods 4 are convenient to understand), as seen in fig. 4, the number of the power groups is four, when the fixed mold 11 moves downwards, firstly the fixed mold 11 contacts with the first power group, the pressing rods 4 of the first power group drive the rotating block A5 to move downwards, at this time, the deflection angle of the tangential plane between the rotating block A5 and the rotating block B9 is 0 °, the rotating block A5 and the rotating block B9 rotate synchronously, in this process, the rotating forces of the rotating block A5 and the rotating block B9 are converted into horizontal thrust of the movable mold 1, at this time, the section between the rotating block A5 and the rotating block B9 of the first power group is perpendicular to the movable die base 2, because the third power group is correspondingly arranged with the first power group, when the movable die 1 moves forward under the thrust of the first power group, the movable die 1 reversely pushes the third power group to slightly move upwards, the third power group has a section of upward idle stroke under the action of the telescopic cylinder 7, when the piston rod of the telescopic cylinder 7 completes the idle stroke movement, the third power group always keeps contact with the movable die 1 under the limit of the telescopic cylinder 7, thereby the movable die 1 generates a reverse thrust to the rotating block A5 and the rotating block B9 of the first power group, and as the fixed die 11 continues to press down, the fixed die 11 continues to press down the first power group while contacting with the second power group, at this time, the deflection angle of the section between the rotating block A5 and the rotating block B9 is 50 DEG, thereby facilitating the formation of a yield for the third power unit.
The motion mode of the second power set is the same as that of the first power set, under the condition that the vertical motion of the second power set is converted into horizontal motion, the movable die 1 moves rightwards, and under the cooperation of the fourth power set, the tangential plane between the rotating block A5 and the rotating block B9 of the second power set is also converted from 0 degree to 50 degrees, so that the fourth power set can be conveniently abducted.
The motion mode of the third power set is the same as that of the second power set, when the fixed die 11 contacts the third power set, the movable die 1 moves backwards under the condition that the vertical motion of the third power set is converted into horizontal motion, the motion mode of the fourth power set is the same as that of the third power set, when the fixed die 11 contacts the fourth power set, the movable die 1 moves leftwards under the condition that the vertical motion of the fourth power set is converted into horizontal motion, and the movable die 1 is sequentially moved through the power sets, so that the movable die 1 is pushed to move along a square line.
In the moving process, a circular shear opening 13 is formed in the center of the movable die 1, and the movable die 1 moves along a square line, so that the circular shear opening 13 of the movable die 1 is matched with the movable die base 2 to perform rotary cutting, and burr cutting of shell workpieces is realized.
According to the transmission device for the horizontal shearing movable die, the surface contact state is kept through the rotating block A5 of the vertical power conversion mechanism and the rotating block B9 of the horizontal power conversion mechanism, so that the abrasion between the rotating block A5 and the rotating block B9 is effectively reduced while the vertical pressure is converted into the horizontal thrust, and the problem that the stroke is shortened after the corner of the traditional inclined wedge is abraded to affect the later shearing operation is solved.
