Description

[0001] The utility model relates to the field of production and processing of sheet metal parts, in particular to a bending tool component capable of realizing continuous adjustment. Background Art

[0002] In the bending process of sheet metal production, Z-shaped bending is often encountered. Due to the forming mechanism, according to the conventional relationship between the sheet thickness and the minimum folding edge, when the turning height is more than 5 times the sheet thickness, the two bends of the turning can be divided into two knives that do not interfere with each other, and the bending process can be completed on the bending machine according to the conventional single-knife bending; when the turning height is less than 5 times the sheet thickness, it cannot be achieved with conventional bending machine tools. In addition to other processing methods such as rolling and forming molding, if the above-mentioned small height turning bend is to be processed on the bending machine, the bending machine must be specially equipped with double-edged upper and lower knives that meet the parameters of this turning bend, and then pressed again.

[0003] However, in the daily sheet metal bending process, there are many turning bends with different parameter combinations (material thickness, turning height, turning angle).

[0028] The lower tool 2 includes a base 13, a T-slot 14 is provided in the base 13, a lower blade plate 15 is movably connected in the T-slot 14, and there is a gap between the bottom of the lower blade plate 15 and the inner wall of the T-slot 14, gap adjustment wedge plates 16 are provided on both sides of the lower blade plate 15, the inclined surface on the gap adjustment wedge plate 16 contacts the inner wall of the base 13, and the inner wall of the base 13 is also an inclined surface, and a gap adjustment bolt 18 is rotatably connected to the second horizontal plate 17 at the top of the gap adjustment wedge plate 16, and the bottom end of the gap adjustment bolt 18 is threadedly connected to the base 13, and a gap locking bolt 31 threadedly connected to the second horizontal plate 17 at the top of the gap adjustment wedge plate 16 is also provided, and the bottom end surface of the gap locking bolt 31 is against the horizontal top surface of the base 13,

[0029] The lower blade plate 15 is connected to a lower floating blade strip 20 via a plurality of equally spaced second connecting bolts 19, and a lower spring 21 is sleeved outside the second connecting bolt 19, the lower spring 21 is located between the step surface 22 of the lower blade plate 15 and the countersunk hole opened in the lower floating blade strip 20, a lower height adjustment wedge pad 23 is provided between the lower floating blade strip 20 and the step surface 22, the top end surface of the lower height adjustment wedge pad 23 is in contact with the bottom end surface of the lower floating blade strip 20, and both are inclined surfaces, a plurality of equally spaced lower horizontal adjustment bolts 25 and a lower horizontal locking bolt 28 threadedly connected thereto are rotatably connected to the second side wall 24 of the lower height adjustment wedge pad 23, the lower horizontal adjustment bolt 25 passes through the lower height adjustment wedge pad 23 The first longitudinal clearance groove 11 in the wedge pad 23 is threadedly connected to the lower knife plate 15, and there is a gap in the longitudinal direction between the inner wall of the first longitudinal clearance groove 11 and the lower horizontal adjustment bolt 25. The lower horizontal locking bolt 28 is threadedly connected to the lower height adjustment wedge pad 23, and its front end surface passes through the third longitudinal clearance groove 30 provided in the lower floating knife strip 20 and then abuts against the upper and lower knife plates 15. There is a gap in the longitudinal direction between the inner wall of the third longitudinal clearance groove 30 and the lower horizontal locking bolt 28. The lower height adjustment wedge pad 23 is provided with a first horizontal clearance groove 12, and the second connecting bolt 19 is located in the first horizontal clearance groove 12. At the same time, there is a gap in the horizontal direction between the inner wall of the first horizontal clearance groove 12 and the second connecting bolt 19.

[0030] The bottom end surface of the upper blade plate 3 corresponds to the top end surface of the lower floating blade strip 20, and the top end surface of the lower blade plate 15 corresponds to the bottom end surface of the upper floating blade strip 6.

[0031] An adjusting gasket 26 is arranged between the upper height-adjusting wedge pad 8 and the upper blade plate 3, and an adjusting gasket 26 is also arranged between the lower height-adjusting wedge pad 23 and the step surface 22 of the lower blade plate 15. The adjusting gasket 26 is provided with a clearance notch matching the first connecting bolt 5 or the second connecting bolt 19 and the upper spring 7 or the lower spring 21.

[0032] The working process of the bending tool assembly that can be continuously adjusted in the embodiment of the utility model is as follows: the plate to be bent is placed between the upper tool 1 and the lower tool 2. At this time, due to the setting of the first connecting bolt 5 and the upper spring 7 in the upper tool 1, the bottom surface of the upper floating blade 6 is flush with the bottom surface of the upper blade plate 3; similarly, due to the setting of the second connecting bolt 19 and the lower spring 21 in the lower tool 2, the top surface of the lower floating blade 20 is also flush with the top surface of the lower blade plate 15. Subsequently, the upper tool 1 moves downward and performs bending operations on the plate together with the lower tool 2. The bottom end surface of the upper knife plate 3 corresponds to the top end surface of the lower floating knife strip 20, and the top end surface of the lower knife plate 15 corresponds to the bottom end surface of the upper floating knife strip 6. As the upper tool 1 moves downward, the plate material clamped between the corresponding working surfaces is forced to continue to produce constrained deformation until the contact surface between the lower floating knife strip 20 and the lower height adjustment wedge pad 23 is compacted, and at the same time, the contact surface between the upper floating knife strip 6 and the upper height adjustment wedge pad 8 is also compacted. Because the inclined surface positions of the adjusted upper height adjustment wedge pad 8 and the lower height adjustment wedge pad 23 respectively limit the displacement heights of the corresponding upper floating knife strip 6 and the lower floating knife strip 20, the plate material finally produces a predetermined turning bending deformation.

[0033] Before the bending operation, adjust the relative position relationship between the upper height-adjusting wedge pad 8 and the upper blade 3, adjust the relative position relationship between the lower blade 15 and the base 13, and adjust the relative position relationship between the lower height-adjusting wedge pad 23 and the lower blade 15 as required, so as to obtain a tool structure that matches the bending size parameters required for processing;

[0034] When it is necessary to adjust the relative position between the upper height adjustment wedge pad 8 and the upper knife plate 3, it is only necessary to rotate the upper horizontal adjustment bolt 10 and the upper horizontal locking bolt 27. Since the upper horizontal adjustment bolt 10 is threadedly connected to the upper knife plate 3, its rotation will drive the upper height adjustment wedge pad 8 rotatably connected thereto to change its position in the horizontal direction. Since the contact surfaces between the upper height adjustment wedge pad 8 and the upper floating knife strip 6 are both inclined surfaces, the horizontal position of the upper height adjustment wedge pad 8 will limit the highest stop position of the longitudinal movement of the upper floating knife strip 6 through the inclined surface, thereby realizing the upper knife adjustment of the turning height; when adjusting, the upper horizontal locking bolt 27 is rotated in coordination, and its front end face abuts against the upper knife plate 3, limiting the horizontal position of the upper height adjustment wedge pad 8 threadedly connected thereto;

[0035] When the relative position between the lower height adjustment wedge pad 23 and the lower blade plate 15 needs to be adjusted, similar to the above process, it is only necessary to rotate the lower horizontal adjustment bolt 25. Since the lower horizontal adjustment bolt 25 is threadedly connected to the lower blade plate 15, its rotation will drive the lower height adjustment wedge pad 23 rotatably connected thereto to change its position in the horizontal direction. Since the contact surfaces between the lower height adjustment wedge pad 23 and the lower floating blade strip 20 are both inclined surfaces, the horizontal position of the lower height adjustment wedge pad 23 will limit the lowest stop position of the longitudinal movement of the lower floating blade strip 20 through the inclined surface, thereby realizing the lower blade adjustment of the turning height; during adjustment, the lower horizontal locking bolt 28 is rotated in coordination, and its front end surface abuts against the lower blade plate 15, limiting the horizontal position of the lower height adjustment wedge pad 23 threadedly connected thereto;

[0036] When the relative position relationship between the lower blade plate 15 and the base 13 needs to be adjusted, the gap adjustment bolt 18 can be rotated (the gap adjustment bolts 18 on both sides need to be adjusted in coordination with each other). Since the gap adjustment bolt 18 is threadedly connected to the base 13, its rotation will drive the gap adjustment wedge plate 16 rotatably connected thereto to move in the longitudinal direction. Since the contact surfaces between the gap adjustment wedge plate 16 and the base 13 are both inclined surfaces, the longitudinal movement of the gap adjustment wedge plate 16 will be converted into pushing the lower blade plate 15 to move horizontally relative to the base 13. After the position between the two is adjusted into place, the gap adjustment wedge plate 16 on the opposite side is used to position the lower blade plate 15, and the gap locking bolts 31 threadedly connected to the gap adjustment wedge plates 16 on each side are rotated to press their bottom end surfaces against the top surface of the base 13, thereby further locking the positions of the gap adjustment wedge plates 16 on each side.

[0037] Through the above adjustment, the highest position of the longitudinal movement of the upper floating knife strip 6 in contact with the upper surface of the workpiece, the lowest position of the longitudinal movement of the lower floating knife strip 20 in contact with the lower surface of the workpiece, and the staggered distance between the upper knife plate 3 and the lower knife plate 15 (that is, the gap between the two, so as to meet the requirements of sheet thickness and turning angle) can be adjusted.

[0038] When pressed down, due to the structure of the tool assembly, there is a certain height difference between the bottom end surface of the upper knife plate 3 and the lower floating knife strip 20, and between the top end surface of the lower knife plate 15 and the upper floating knife strip 6. The existence of this height difference will cause the tool assembly to form two bent shapes, i.e., a Z-shape, after impacting the plate workpiece.

[0039] Moreover, the operator can adjust the stop height of the upper and lower floating blades and the horizontal position between the two blades according to actual needs, so as to realize the processing of various Z-shaped shapes of different specifications with a set of tool components, which has strong versatility and can effectively reduce production costs.

[0040] When it is necessary to quickly and significantly adjust the stop height of the upper and lower floating blades, it can be achieved by adding or removing the adjustment gaskets 26 (or replacing the adjustment gaskets 26 with different thicknesses).
