Example 1
In this embodiment, the upper tool holder 5 is changed from a fixed type to a floating type, and the specific structure thereof is that the left and right adjusting mechanism 13 of the upper tool holder includes two sides respectively arranged on the upper tool holder 5 and the upper tool apron 4 along the width direction, and includes stoppers 16 fixed on two sides of the upper tool apron 4, the lower ends of the stoppers 16 extend to two sides of the upper tool holder 5, a transverse step screw 17 is designed below the stopper 16, the transverse step screw 17 passes through a counter bore on the outer side of the stopper 16 and a disc spring group 18 and is locked on a nut 19, the disc spring group 18 is installed in the counter bore on the inner side of the stopper 16, and the nut 19 contacts the side surface of the upper tool holder 5. The upper tool rest vertical limiting mechanism 14 comprises a vertical adjusting screw, the vertical adjusting screw penetrates through an open slot of the upper tool rest 5 and is locked on the upper tool apron 4, a disc spring group 18 is arranged between a vertical step screw 20 and the upper tool rest 5, and flat washers 21 are arranged above and below the disc spring group 18. In the above embodiment, the upper tool holder 5 can freely move in the left-right direction with respect to the upper tool holder 4 by means of the vertical position-limiting mechanism and the left-right adjusting mechanism in cooperation with the 2-position flat key 12 between the upper tool holder 5 and the upper tool holder 4. As shown in fig. 3, when the central line of the upper tool rest 5 is not aligned with the central line of the lower tool rest 9, and the upper guide plate 6 enters the lower guide plate 10, the upper tool rest 5 can be adjusted left and right, so that the upper guide plate 6 can freely enter the lower guide plate 10, the lateral stress of the guide plate is reduced, and the guide plate and the lower tool rest 9 are prevented from being damaged.
Two sides of the upper tool rest 5 are respectively provided with a row of vertical limiting mechanisms. In the vertical limiting mechanism, a vertical adjusting screw penetrates through an open slot of an upper tool rest 5 and is locked on an upper tool apron 4, a disc spring group 18 is designed between a vertical step screw 20 and the upper tool rest 5, and flat washers 21 are arranged above and below the disc spring group 18. The mechanism presses an upper tool rest 5 on an upper tool apron 4 through a disc spring group 18, the upper tool rest 5 is in a floating state relative to the upper tool apron 4, when the upper tool rest 5 is subjected to external lateral force, the upper tool rest 5 moves left and right, at the moment, the contact surface of the upper tool rest 5 and the upper tool apron 4 generates friction displacement, and the contact surface of a flat gasket 21 above the disc spring group 18 and the upper tool rest 5 generates friction displacement.
As shown in fig. 4, in the left-right adjusting mechanism, 2 stoppers 16 are respectively installed on two sides of the upper tool apron 4, each stopper 16 is fixed on the upper tool apron 4 through 2 screws above, a transverse step screw 17 is designed below each stopper 16, the transverse step screw 17 passes through a counter bore on the outer side of each stopper 16 and a disc spring group 18 and is locked on a nut 19, the disc spring group 18 is installed in a counter bore on the inner side of each stopper 16, and the nut 19 contacts with the side surface of the upper tool rest 5. When the upper tool rest 5 is subjected to lateral external force, the upper tool rest 5 generates displacement, and after the external force is lost, the left and right adjusting mechanisms on the two sides of the upper tool rest 5 enable the upper tool rest 5 to recover the initial state. A3 mm gap exists between the transverse step screw 17 and a counter bore on the outer side of the stop block 16, and the gap plays a limiting role, namely, the upper tool rest 5 can only move 3mm in the left direction or the right direction. In the upper shearing mechanism, the upper blades 7 are fixed on two sides of the upper tool rest 5 through locking screws and nuts 19, and the two upper blades 7 mutually form an angle of 2 degrees, namely, the shape of a Chinese character 'ba', and the design is to only enable the cutting edges to shear strip steel, so that the outer side surfaces of the blades are prevented from scratching the strip steel, and the influence on the shearing quality is avoided.
Example 2
In the above embodiment, the surface of the adjustment block 22 close to the blade is a 1 ° inclined surface, and the other side is a vertical surface, and since the side surface of the lower blade 11 is also installed at 91 ° to the horizontal surface, the adjustment block 22 and the lower blade 11 are in inclined surface contact. When the setting ramp 22 is moved downwards, the blade cutting edge clearance will be smaller here. The right side of the positioning key 23 is matched with the vertical groove of the lower tool rest 9, the left side of the positioning key is matched with the vertical groove of the adjusting inclined block 22, and the mechanism can enable the adjusting inclined block 22 to be adjusted only in the vertical direction without lateral displacement. At the same time, two swash block locking screws 29 pass through the lower tool holder 9 to lock the adjustment swash blocks 22, and each set of adjustment swash blocks 22 is in contact with the adjacent adjustment swash blocks 22. In order to conveniently adjust the up-and-down movement of the inclined block 22, a gear shaft 24 is designed above the lower blade locking screw 25, and a gear on the gear shaft 24 is meshed with a strip-shaped tooth on the side wall of a central slot hole of the inclined block 22. A groove is formed between the gear and the boss on the gear shaft 24, and the groove and the boss are matched with the counter bores on the positioning keys 23 to limit the axial displacement of the gear shaft 24. As shown in FIG. 1, the counter bore on the position key 23 is a laterally open counter bore, and the gear shaft 24 can slide laterally into the center of the position key 23. After the gear shaft 24 and the positioning key 23 are assembled separately, the shaft at the tail end of the gear shaft 24 is installed in the corresponding through hole of the lower tool rest 9, and at the moment, the right side of the positioning key 23 is matched with and enters the vertical groove of the lower tool rest 9. The tail end of the gear shaft 24 is provided with a hexagonal counter bore, and the gear shaft 24 can be adjusted to rotate by an inner hexagonal wrench to drive the adjusting inclined block 22 to move up and down, namely, the shear blade clearance is adjusted.
Since the slope of the slope on the left side of the adjustment ramp 22 is constant, the relationship between the amount of vertical displacement of the adjustment ramp 22 and the change in the cutting edge clearance can be calculated. Through calculation, when the adjusting inclined block 22 moves downwards by 1mm, the lower blade 11 moves 0.017mm towards the center of the lower blade carrier 9, namely the blade cutting gap is reduced by 0.017mm, and otherwise, the blade cutting gap is increased by 0.017 mm.
When the cutting edge clearance needs to be adjusted, the lower blade locking screw 25 at the position is loosened in the first step, the inclined block locking screw 29 at the position is loosened in the second step, the gear shaft 24 is rotated by an inner hexagonal wrench to drive the inclined block to move up and down, the moving amount of the up-and-down movement of the adjusting inclined block 22 can be monitored by a vernier depth gauge, the adjusted cutting edge clearance is calculated, and the lower blade locking screw 25 and the inclined block locking screw 29 are locked after the adjustment is completed.
