[0038] Example 1
[0039] like Figure 3 to Figure 5 As shown, the present embodiment proposes a bending correction tool, which includes an upper fixed plate 1 and a plunger 2 connected to the upper fixed plate 1; further includes a lower fixed plate 3 and a fixed block 4 arranged on the lower fixed plate 3; further includes a slider 5 movably arranged on the fixed block 4 along a first straight line; wherein the first straight line is parallel to the plate surface direction of the upper fixed plate 1 and the plate surface direction of the lower fixed plate 3; a first inclined surface 6 is arranged on the side of the plunger 2 facing the slider 5, and a second inclined surface 7 is arranged on the side of the slider 5 facing the plunger 2, the first inclined surface 6 and the second inclined surface 7 are parallel to each other, and are respectively at preset angles to the first straight line; further includes a limiting column 8, the limiting column 8 is connected to the lower fixed plate 3, the limiting column 8 has a limiting surface 9, and the limiting surface 9 is located at a preset position between the upper fixed plate 1 and the fixed block 4.
[0040] The bending correction tool of this embodiment is arranged on a riveting machine for use; in this embodiment, the first straight line is along the horizontal direction, and the second straight line is along the vertical direction.
[0041] The upper fixing plate 1 is a plate-shaped structure, which is connected to the movable end of the riveting machine.
[0042] The lower fixing plate 3 is also a plate-shaped structure, which is connected to the fixing end of the riveting machine.
[0043] The limiting column 8 is a column structure, and its number can be configured as one or more. For example, multiple limiting columns 8 are arranged in parallel with each other, and any limiting column extends along the second straight line; the limiting surface 9 is located at a preset position between the upper fixed plate 1 and the fixed block 4, and the preset position can be configured according to specific circumstances. The setting of the preset position should satisfy that when the upper fixed plate 1 and the limiting surface contact each other, it indicates that the bending edge is bent in place. At this time, the movement of the upper fixed plate 1 toward the lower fixed plate 3 is restricted by the limiting surface and stops moving.
[0044] The shape of the fixing block 4 is not limited. Preferably, the fixing block 4 is a block structure with a rectangular cross section.
[0045] The shape of the slider 5 can be set according to the specific usage. Preferably, the slider 5 is a regular geometric shape for easy processing. The slider can slide on the fixed block 4. Preferably, in the present embodiment, the slider 5 is provided with a protrusion, and the fixed block 4 is provided with a guide groove. The slider 5 and the fixed block 4 form a sliding pair along the first straight line through the protrusion and the guide groove. In the present embodiment, the guide groove provided on the fixed block 4 guides the movement of the slider 5 along the first straight line.
[0046] Reference Figure 5-6 , further preferably, in order to prevent the slider 5 and the fixed block 4 from separating from each other along the direction indicated by the second straight line; the present embodiment also includes the following technical scheme: a first engaging portion is provided on the surface of the slider 5, and a second engaging portion is provided in the guide groove, and along the direction indicated by the second straight line, the slider 5 is inseparably restricted in the guide groove through the engaging relationship formed by the first engaging portion and the second engaging portion; for example, in the present embodiment, the first engaging portion is a wedge-shaped protrusion provided on the slider 4, and the second engaging portion is a wedge-shaped recessed portion provided in the guide groove, and the engaging structure formed by the two makes it impossible for the slider 5 and the fixed block 4 to separate along the direction indicated by the second straight line.
[0047] The structure of the insert knife 2 can be configured as a special-shaped structure, and the insert knife 2 and the upper fixed plate 1 can be detachably connected; a first inclined surface 6 is provided on the side of the insert knife 2 facing the slider 5, and a second inclined surface 7 is provided on the side of the slider 5 facing the insert knife 2; preferably, the preset angle is an acute angle, that is, the first inclined surface 6 and the second inclined surface 7 are respectively acute angles with the vertical direction; the upper fixed plate 1 can drive the insert knife 2 to move in the direction where the lower fixed plate 3 is located, and the first inclined surface 6 and the second inclined surface 7 contact each other and slide relatively, so that the slider 5 slides on the fixed block 4 along the first straight line; in this process, the movement of the insert knife along the second straight line is converted into the movement of the slider 5 along the first straight line through the first inclined surface 6 and the second inclined surface 7; the slider 5 can push the bending edge to deform until the bending edge and the reference edge form a right angle.
[0048] In combination with the background technology, it can be known that the technical problem existing in the prior art is the lack of a bending correction tool that can rework and bend a bracket that is not bent into place.
[0049] In the present embodiment, a bending correction tool is proposed, which, through the arrangement of the first inclined surface 6 and the second inclined surface 7, converts the movement of the insert 2 along the second direction, i.e., the vertical direction, into the movement of the slider 5 along the first direction, i.e., the horizontal direction, so that the slider 5 pushes the bending edge of the rework bracket product to deform; at the same time, a limiting column 8 is also provided in the present embodiment, and the limiting column 8 has a limiting surface 9. When the upper fixed plate 1 contacts the limiting surface 9 of the limiting column 8, it represents that the bent edge is at a right angle to the reference edge; that is, in the present embodiment, the worker can use the bending correction tool proposed in the present embodiment to rework and bend the bracket product that is not bent in place; in summary, the present embodiment solves the technical problem of the lack of a bending correction tool in the prior art, and the bending correction tool can rework and bend the bracket that is not bent in place.
[0050] like Figure 3 to Figure 5 As shown, further, it is mentioned in the foregoing content that the inserting knife 2 can push the slider 5 to slide along the first straight line through the first inclined surface 6 and the second inclined surface 7. In order to enable the slider 5 to automatically return to its original position after the inserting knife 2 is lifted in the direction away from the lower fixed plate, the present embodiment also includes the following technical solutions:
[0051] The bending correction tool also includes a limit block 10 and a spring 11. The limit block 10 is connected to the lower fixed plate 3. One end of the spring 11 abuts against the limit block 10, and the other end abuts against the slider 5. In this embodiment, when the inserting knife 2 pushes the slider 5 to slide along the first straight line through the first inclined surface 6 and the second inclined surface 7, the spring 11 contracts. After the inserting knife 2 is lifted in the direction away from the lower fixed plate, the spring 11 pushes the slider 5 back to its original position under the action of its own elastic force.
[0052] Furthermore, the present embodiment also includes the following technical solution: the limit block 10 is provided with a first hole 12, the slider 5 is provided with a second hole 13, one end of the spring 11 is restricted in the first hole 12, and the other end is restricted in the second hole 13; in the present embodiment, the two ends of the spring 11 are respectively restricted in the first hole 12 and the second hole 13, along the direction indicated by the second straight line, to prevent the spring 11 from being separated from the limit block 10 and the slider 5.
[0053] Depend on Figure 1-2 As shown, the bracket has two bent edges. In order to match the shape of the bracket, in this embodiment, the number of the inserting knife 2 is one, and the two sides of the inserting knife 2 are respectively provided with a first inclined surface 6; the combination of the slider 5, the spring 11, and the limit block 10 is a first component, and the number of the first components is two. Along the first straight line, the inserting knife 2 is located between the two first components.
[0054] As mentioned above, after sliding, the slider 5 returns to its original position under the action of the spring 11. If one of the sliders 5 returns to its original position excessively, the positions of the first inclined surface 6 and the second inclined surface 7 along the first straight line will not correspond, that is, when the inserting knife 5 moves downward, it directly contacts the upper surface of one of the sliders 5 instead of the second inclined surface 7 of the slider 5, causing the upper surface of the slider 5 to be crushed. Therefore, how to avoid excessive return of the slider 5 is a technical problem that needs to be solved, and the technical problem is solved by the following technical solution.
[0055] like Figure 4-5 As shown, the bending correction tool of this embodiment also includes a limiting nail 14, and the fixing block 4 is provided with a clearance hole 15. One end of the limiting nail 14 is fixed to the lower fixing plate 3, and the other end penetrates the clearance hole 15 and extends between the two first components; the central axis of the limiting nail 14 coincides with the central axis of the inserting knife 2, or is parallel to each other and has a preset spacing.
[0056] In this embodiment, the most preferred solution is that the central axis of the limiting pin 14 coincides with the central axis of the inserting knife 2; the less preferred solution is that the central axis of the limiting pin 14 is parallel to the central axis of the inserting knife 2 and there is a preset spacing. The setting of the preset spacing can be configured according to specific circumstances. The preset spacing should be configured so that after the inserting knife 2 moves downward along the first straight line, it can avoid the upper surface of the slider 5 and contact the second inclined surface 7 of the slider 5.
[0057] In this embodiment, after the inserting knife 5 is lifted upward, a limiting pin 14 is arranged between the two first components, so that the sliders 5 of the two first components, after being pushed by their corresponding springs, hit the side of the limiting pin 14 and stop moving; and the central axis of the limiting pin 14 coincides with the central axis of the inserting knife 2, or is parallel to each other and has a preset spacing, which can make the sliders 5 of the two first components symmetrically arranged or approximately symmetrically arranged relative to the central axis of the inserting knife 2; and then after the slider 5 returns, the inserting knife 5 moves downward again, can avoid the upper surface of the slider 5, and contact with the second inclined surface 7 of the slider 5, thereby avoiding the occurrence of crushing of the upper surface of the slider 5; in summary, this embodiment solves the technical problem of how to avoid excessive return of the slider 5.
[0058] Furthermore, the bending correction tool of this embodiment also includes a guide column assembly, and the upper fixing block 4 is movably connected to the lower fixing block 4 through the guide column assembly, and the movable direction of the upper fixing block 4 is along the direction indicated by the second straight line. The structure of the guide column assembly is prior art and will not be described in detail here.
[0059] like Figure 3-4As shown, further, the bending correction tool of this embodiment also includes a stopper 16, which is connected to the fixed block 4. Along the first direction, there is a preset distance between the stopper 16 and the slider 5; there are multiple stoppers 16.
[0060] In this embodiment, a stopper 16 is proposed, and there are multiple stoppers. The arrangement rules and shapes of the stoppers on the fixed block 4 can be configured according to the shape of the bent part, that is, the bracket; the preset distance between the stopper and the slider 5 can also be configured according to specific circumstances. For example, in this embodiment, the preset distance is 0.05 mm; when in use, the bracket that needs to be reworked is placed on the fixed block 4, and during the process of the slider 5 pushing the bending edge, the bending edge gradually deforms and finally contacts the stopper 16; the purpose of setting the stopper is to prompt the worker with information: if the bending edge contacts the stopper, it means that the bending edge is now at a right angle to the reference edge; combined with the foregoing, the moment when the upper fixed plate 1 contacts the limiting surface, that is, the moment when the bending edge contacts the stopper, the two should be configured to occur simultaneously.
[0061] Furthermore, the position of the reference edge can be limited by one or more of the stoppers to prevent the reference edge from moving during the rework and bending process.
[0062] like Figure 7-Figure 8 As shown, when in use, the pallet to be reworked is placed on the fixed block 4; the movable end of the riveting machine drives the upper fixed plate 1 to move vertically downward, that is, it moves along the second direction toward the lower fixed plate 3, and the two first inclined surfaces 6 set on both sides of the inserting knife 2 respectively contact the second inclined surfaces 7 of the sliders 5 of the two first components, and the two sliders 5 slide in opposite directions along the guide grooves, one of the sliders 5 pushes one of the bending edges of the pallet to deform, and the other slider 5 pushes the other bending edge of the pallet to deform, until the two bending edges are in contact with their respective corresponding stoppers 16, and the upper fixed plate 1 and the limiting surface are in contact with each other, and the bending is in place at this time; the movable end of the riveting machine drives the upper fixed plate 1 to move vertically upward, that is, it moves along the second direction toward the direction away from the lower fixed plate 3, the inserting knife 2 is lifted upward, the first inclined surface 6 is separated from the second inclined surface 7, and the springs 11 of the two first components respectively push their respective corresponding sliders 5 to slide, and the two sliders 5 approach each other until they hit the limiting nail 14 and stop; remove the bent rework pallet to complete the rework process.
[0063] The bending correction tool of this embodiment has the advantages of simple structure, convenient production and operation, and low cost.
[0064] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
