Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending equipment, and in particular to a sheet metal bending mechanism. Background Technology

[0002] In household appliances, it is often necessary to bend sheet metal parts to achieve the required bending structure. For example, Figures 13-14 As shown, sheet metal parts need to be bent twice using two sets of molds to be formed. This bending method seriously affects production efficiency. Moreover, the need to move the sheet metal parts during the two bending processes makes it impossible to guarantee the quality of the bent products and also increases production costs. Utility Model Content

[0003] The purpose of this utility model is to provide a sheet metal bending mechanism to solve the technical problem that existing sheet metal bending mechanisms cannot complete two bends simultaneously, resulting in low production efficiency.

The bending block is provided on one side of the lower floating material plate and can complete the first bending when the upper pressing base presses down on the lower floating material plate.

[0008] The side slider can be slidably mounted on the upper mold base in a manner that is close to or far from the upper pressure base in order to complete the second bending.

[0009] As an optional implementation, a guide seat is provided on the lower mold base, and the guide seat is provided corresponding to the side slider;

[0010] When the upper pressure base presses down on the lower floating plate, the side slider cooperates with the guide seat to drive the side slider to move closer to the upper pressure base, so as to complete the second bending between the side slider and the upper pressure base.

When the lower floating material plate is in the initial position, the bending block and the top surface of the lower floating material plate are flat.

[0019] The lifting assembly drives the upper mold base to move closer to the lower mold base, which in turn drives the upper pressure base to move downward and moves the lower floating plate downward to compress the first elastic element, thereby completing the first bending of the sheet metal part between the bending block and the unloading floating plate.

[0020] As an optional implementation, a second elastic element is further provided between the side slider and the upper mold base, and the elastic force of the second elastic element is used to drive the side slider away from the upper pressure base.

[0021] As an optional implementation, the side slider is provided with a second slide groove, and the upper mold base is provided with a second slider. The second slider cooperates with the second slide groove so that the side slider can be slidably disposed on the upper mold base in a manner that is close to or far away from the upper pressure base.

[0022] The beneficial effects of this utility model are as follows: The sheet metal bending mechanism provided by this utility model includes an upper die base and a lower die base. The upper die base is provided with an upper pressure base and a side slider. The lower die base is provided with a bending block and a lower floating plate.

When the lower floating plate is in its initial position, the top surfaces of the bending block and the lower floating plate are flat. The upper die base is provided with an upper pressing base and a side slider. The side slider can be slidably disposed on the upper die base in a manner that moves closer to or away from the upper pressing base. When the lifting assembly drives the upper die base and the lower die base to move closer to each other, the upper pressing base... The base can drive the lower floating plate to move up and down, enabling the lower floating plate and the bending block to move relative to each other, thereby completing the first bending of the sheet metal part between the lower floating plate and the bending block. Since the side slider can be slidably disposed on the upper die base in a manner that is close to or away from the upper pressure base, the reciprocating drive structure is used to drive the side slider to move closer to the upper pressure base, so as to complete the second bending of the sheet metal part between the side slider and the upper pressure base.

[0047] This utility model provides a sheet metal bending mechanism that improves production efficiency.

[0048] The following is combined Figures 1 to 14 The technical solution provided by this utility model will be described in more detail.

[0049] This utility model provides a sheet metal bending mechanism, including:

[0050] Upper mold base 1, wherein an upper pressure base 11 and a side slider 12 are provided on the upper mold base 1, and the side slider 12 can be slidably disposed on the upper mold base 1 in such a way as to be close to or away from the upper pressure base 11;

[0051] The lower die base 2 is provided with a bending block 21 and a lower floating plate 22. The lower floating plate 22 is correspondingly provided with the upper pressing base 11. The bending block 21 is provided on one side of the lower floating plate 22, and a first elastic element 23 is provided between the lower floating plate 22 and the lower die base 2. The elastic force of the first elastic element 23 drives the lower floating plate 22 to the initial position. When the lower floating plate 22 is in the initial position, the top surfaces of the bending block 21 and the lower floating plate 22 are flat.

[0052] A lifting assembly is connected to the upper mold base 1 to drive the upper mold base 1 to move closer to or further away from the lower mold base 2;

[0053] The lifting assembly drives the upper mold base 1 to move closer to the lower mold base 2, which can drive the upper pressure base 11 to move downward and move the lower floating plate 22 to move downward to compress the first elastic member 23, so as to complete the first bending of the sheet metal part between the bending block 21 and the lower floating plate.

[0054] A reciprocating drive structure is used to drive the side slider 12 to move closer to the upper pressure base 11, so as to complete the second bending of the sheet metal part between the side slider 12 and the upper pressure base 11.

[0055] The sheet metal bending mechanism provided by this utility model includes an upper die base 1, a lower die base 2, and a lifting assembly. The lifting assembly can drive the upper die base 1 and the lower die base 2 to move closer to each other. The lower die base 2 is provided with a bending block 21 and a lower floating plate 22. A first elastic element 23 is provided between the lower floating plate 22 and the lower die base 2. When the lower floating plate 22 is in the initial position, the top surfaces of the bending block 21 and the lower floating plate 22 are flat. The upper die base 1 is provided with... The upper pressure base 11 and the side slider 12 are provided. The side slider 12 can be slidably disposed on the upper mold base 1 in a manner that is close to or far away from the upper pressure base 11. When the lifting assembly drives the upper mold base 1 and the lower mold base 2 to move closer to each other, the upper pressure base 11 can drive the lower floating plate 22 to move up and down, so that the lower floating plate 22 and the bending block 21 can move relative to each other, thereby completing the first bending of the sheet metal part between the lower floating plate 22 and the bending block 21.

[0056] Since the side slider 12 can be slidably disposed on the upper mold base 1 in a manner that is close to or far from the upper pressure base 11, the reciprocating drive structure is used to drive the side slider 12 to move closer to the upper pressure base 11 so as to complete the second bending of the sheet metal part between the side slider 12 and the upper pressure base 11. Thus, the sheet metal bending mechanism provided by this utility model can realize two bending processes at the same time, thereby greatly improving production efficiency. Moreover, completing two bends at once can effectively ensure product quality and reduce production costs.

[0057] It is understood that the elastic force of the first elastic element 23 drives the lower floating plate 22 to the initial position. When the lower floating plate 22 is in the initial position, the top surfaces of the bending block 21 and the lower floating plate 22 are flat. The sheet metal part to be bent is placed on the bending block 21 and the lower floating plate 22. The sheet metal part to be bent is fixed at the required bending position. As the upper pressure base 11 contacts the lower floating plate 22 under the drive of the lifting component and drives the lower floating plate 22 to move downward and compress the first elastic element 23, the lower floating plate 22 and the upper pressure base 11 will clamp the sheet metal part to be bent and move downward, so that the sheet metal part to be bent completes the first bending of the sheet metal part at the position between the bending block 21 and the lower floating plate 22. After the first bending is completed, the reciprocating drive structure drives the side slider 12 to move closer to the upper pressure base 11, and the second bending can be completed between the side slider 12 and the upper pressure base 11.

[0058] In some embodiments of this utility model, the reciprocating drive structure includes a guide seat 24, which is disposed on the lower mold base 2 and is correspondingly disposed with the side slider 12;

[0059] As the upper mold base 1 continues to move closer to the lower mold base 2, the side slider 12 cooperates with the guide seat 24 to drive the side slider 12 to move closer to the upper pressure base 11, so as to complete the second bending of the sheet metal part between the side slider 12 and the upper pressure base 11.

[0060] In some embodiments of the present invention described above, the reciprocating drive structure includes a guide seat 24, which is disposed on the lower mold base 2. The guide seat 24 is disposed corresponding to the side slider 12. By moving the upper mold base 1 and the lower mold base 2 closer to each other, the side slider 12 is driven to move closer to the upper pressure base 11, thereby completing the second bending. This reduces the use of the drive source and lowers production costs.

[0061] It should be noted that the reciprocating drive structure can also use existing reciprocating drive components, such as motor lead screw slider assembly or cylinder drive assembly.

[0062] In some specific embodiments of this utility model, the guide seat 24 is provided with a first inclined surface 241, and the side slider 12 is provided with a second inclined surface 122, the first inclined surface 241 and the second inclined surface 122 cooperate with each other.

[0063] In some specific embodiments of the present invention described above, the guide seat 24 and the side slider 12 are respectively provided with a first inclined surface 241 and a second inclined surface 122. The first inclined surface 241 and the second inclined surface 122 cooperate with each other, so that the side slider 12 can slide along the first inclined surface 241 and the second inclined surface 122 on the guide seat 24, ensuring that when the first bend is completed, the side slider 12 contacts the upper pressure base 11 to complete the second bend.

[0064] In some embodiments of this utility model, the upper pressure base 11 includes a base body 13 and a sliding seat 14. The base body 13 is provided with a first sliding groove 131, and the sliding seat 14 is provided with a first slider 141. The first slider 141 and the first sliding groove 131 cooperate to allow the sliding seat 14 to be slidably disposed on the base body 13.

[0065] In some embodiments of the present invention described above, the upper pressure base 11 includes a base body 13 and a sliding seat 14. The sliding seat 14 is slidably disposed on the base body 13. Before the first bend is completed, the sliding seat 14 can contact the sheet metal part to be bent on the lower floating plate 22 before the base body 13 and press it onto the sheet metal part to be bent. After the second bend is completed, the sliding seat 14 can separate from the formed sheet metal part on the lower floating plate 22 after the base body 13, ensuring the forming effect of the formed sheet metal part.

[0066] In some embodiments of this utility model, the sliding seat 14 is disposed on the side close to the side slider 12, and the sheet metal part is bent a second time between the side slider 12 and the sliding seat 14.

[0067] In some embodiments of the present invention described above, the sliding seat 14 is disposed on the side close to the side slider 12. The sheet metal part is bent for the second time between the side slider 12 and the sliding seat 14. After the second bend is completed, the sliding seat 14 can separate from the formed sheet metal part on the lower floating plate 22 after the base body 13. The two bending positions of the formed sheet metal part are in contact with the sliding seat 14, which can avoid the problem of damage to the formed sheet metal part caused by external force and ensure the finished product effect.

[0068] In some embodiments of this utility model, a limiting block 132 is provided on the base body 13, and a limiting groove 142 is provided on the first slider 141, wherein the limiting block 132 cooperates with the limiting groove 142.

[0069] In some of the embodiments of this utility model described above, by setting the limiting block 132 and the limiting groove 142, the sliding position of the sliding seat 14 on the base body 13 can be limited, thereby playing a limiting role.

[0070] In some embodiments of this utility model, the base body 13 is provided with a third inclined surface 133, the sliding seat 14 is provided with a fourth inclined surface 143, the third inclined surface 133 and the fourth inclined surface 143 cooperate, the first slider 141 is provided on the fourth inclined surface 143, and the first sliding groove 131 is provided on the third inclined surface 133.

[0071] In some embodiments of the present invention described above, the sliding seat 14 and the base body 13 are respectively provided with a third inclined surface 133 and a fourth inclined surface 143. The third inclined surface 133 and the fourth inclined surface 143 cooperate to enable the sliding seat 14 to slide along the inclined direction. When the second bend is completed and the lifting component moves upward, the sliding seat 14 separates from the formed sheet metal part on the lower floating plate 22 after the base body 13, and can gradually move away from the formed sheet metal part, thereby realizing the separation of the formed sheet metal part, completing the automatic unloading of the formed sheet metal part, and reducing the labor intensity of employees.

[0072] In some embodiments of this utility model, a third elastic element 15 is further provided between the sliding seat 14 and the upper mold seat 1, and the elastic force of the third elastic element 15 drives the sliding seat 14 away from the upper mold seat 1.

[0073] In some embodiments of the present invention described above, by providing a third elastic element 15, the elastic force of the third elastic element 15 drives the sliding seat 14 away from the upper mold base 1, thereby enabling the sliding seat 14 to move away from the upper mold base 1 under the elastic force of the third elastic element 15. This ensures that before the first bend is completed, the sliding seat 14 can contact the sheet metal part to be bent on the lower floating plate 22 before the base body 13 and press it onto the sheet metal part to be bent; after the second bend is completed, the sliding seat 14 can separate from the formed sheet metal part on the lower floating plate 22 after the base body 13.

[0074] In some embodiments of this utility model, a second elastic element 16 is further provided between the side slider 12 and the upper mold base 1, and the elastic force of the second elastic element 16 is used to drive the side slider 12 away from the upper pressure base 11.

[0075] In some embodiments of the present invention described above, a second elastic element 16 is further provided between the side slider 12 and the upper mold base 1. The elastic force of the second elastic element 16 can drive the side slider 12 to move away from the upper pressure base 11. When the lifting assembly drives the upper mold base 1 and the lower mold base 2 to move closer together, when the guide seat 24 contacts the side slider 12, the guide seat 24 can drive the side slider 12 to move closer to the upper pressure base 11 to compress the second elastic element 16. When the lifting assembly drives the upper mold base 1 and the lower mold base 2 to move away from each other, the elastic force of the second elastic element 16 can drive the side slider 12 away from the upper pressure base 11, thereby realizing the automatic reset of the side slider 12, reducing the use of the driving source, and reducing production costs.

[0076] In some embodiments of this utility model, the side slider 12 is provided with a second slide groove 121, and the upper mold base 1 is provided with a second slider 17. The second slider 17 cooperates with the second slide groove 121 so that the side slider 12 can be slidably disposed on the upper mold base 1 in a manner that is close to or far away from the upper pressure base 11.

[0077] In some embodiments of the present invention described above, the side slider 12 and the upper mold base 1 are slidably engaged by the second slider 17, so that the side slider 12 can be slidably disposed on the upper mold base 1 in a manner that is close to or far from the upper pressure base 11.

[0078] Example 1:

[0079] The sheet metal bending mechanism provided by this utility model includes:

[0080] The upper mold base 1 is provided with an upper pressure base 11 and a side slider 12. The side slider 12 is provided with a second sliding groove 121. The upper mold base 1 is provided with a second slider 17. The second slider 17 cooperates with the second sliding groove 121 so that the side slider 12 can slide on the upper mold base 1 in a manner that is close to or away from the upper pressure base 11.

[0081] The lower die base 2 is provided with a bending block 21, a lower floating material plate 22 and a guide seat 24. The lower floating material plate 22 is correspondingly provided with the upper pressing base 11. The bending block 21 is provided on one side of the lower floating material plate 22, and a first elastic member 23 is provided between the lower floating material plate 22 and the lower die base 2. The elastic force of the first elastic member 23 drives the lower floating material plate 22 to the initial position. When the lower floating material plate 22 is in the initial position, the top surfaces of the bending block 21 and the lower floating material plate 22 are flat.

[0082] The guide seat 24 is disposed on the lower mold base 2, and the guide seat 24 is correspondingly disposed to the side slider 12. The guide seat 24 is provided with a first inclined surface 241, and the side slider 12 is provided with a second inclined surface 122. The first inclined surface 241 and the second inclined surface 122 cooperate with each other. A second elastic element 16 is also disposed between the side slider 12 and the upper mold base 1. The elastic force of the second elastic element 16 is used to drive the side slider 12 away from the upper pressure base 11.

[0083] A lifting assembly is connected to the upper mold base 1 to drive the upper mold base 1 to move closer to or further away from the lower mold base 2;

[0084] The lifting assembly drives the upper mold base 1 to move closer to the lower mold base 2, which can drive the upper pressure base 11 to move downward and move the lower floating plate 22 to move downward to compress the first elastic member 23, so as to complete the first bending of the sheet metal part between the bending block 21 and the lower floating plate.

[0085] As the upper mold base 1 continues to move closer to the lower mold base 2, the side slider 12 cooperates with the guide seat 24 to drive the side slider 12 to move closer to the upper pressure base 11, so as to complete the second bending of the sheet metal part between the side slider 12 and the upper pressure base 11.

[0086] Example 2:

[0087] The difference between Embodiment 2 and Embodiment 1 is that the upper pressure base 11 includes a base body 13 and a sliding seat 14. The sliding seat 14 is disposed on the side close to the side slider 12. The base body 13 is provided with a first sliding groove 131, and the sliding seat 14 is provided with a first slider 141. The first slider 141 and the first sliding groove 131 cooperate to allow the sliding seat 14 to be slidably disposed on the base body 13. The sheet metal part is bent a second time between the side slider 12 and the sliding seat 14.

[0088] Furthermore, a limiting block 132 is provided on the base body 13, and a limiting groove 142 is provided on the first slider 141, with the limiting block 132 cooperating with the limiting groove 142.

[0089] Furthermore, the base body 13 is provided with a third inclined surface 133, the sliding seat 14 is provided with a fourth inclined surface 143, the third inclined surface 133 and the fourth inclined surface 143 cooperate with each other, the first slider 141 is provided on the fourth inclined surface 143, and the first sliding groove 131 is provided on the third inclined surface 133.

[0090] Furthermore, a third elastic element 15 is provided between the sliding seat 14 and the upper mold base 1, and the elastic force of the third elastic element 15 drives the sliding seat 14 away from the upper mold base 1.

[0091] The working process of the sheet metal bending mechanism provided in this embodiment 2 is as follows:

[0092] like Figure 1 The diagram shown is a schematic of the sheet metal bending mechanism in its initial position.

[0093] When the lifting assembly drives the upper mold base 1 and the lower mold base 2 to move closer to each other, the sliding seat 14 will first contact the sheet metal part to be bent and gradually press the sheet metal part. The sliding seat 14 will then move upward until the base body 13 and the sliding seat 14 are simultaneously pressed against the sheet metal part to be bent (e.g., Figure 7 (as shown); simultaneously, the side slider 12 will move towards the sliding seat 14 under the action of the guide seat 24 (as shown). Figure 7 (as shown);

[0094] As the lifting assembly drives the upper mold base 1 to continue descending, it causes the lower floating plate 22 to descend and compress the first elastic element 23, thereby completing the first bending of the sheet metal part between the bending block 21 and the lower floating plate (e.g., Figure 8 (as shown); simultaneously, the side slider 12 will move towards the sliding seat 14 under the action of the guide seat 24 (as shown). Figure 8 (as shown);

[0095] As the lifting assembly drives the upper mold base 1 to continue descending into position, the side slider 12 moves towards the sliding seat 14 under the action of the guide seat 24, allowing the sheet metal part to be bent to complete a second bend between the side slider 12 and the sliding seat 14 (e.g., Figure 9-10 (as shown); until the second bend is completed (as shown). Figure 9-10 (as shown);

[0096] After the second bending is completed, the lifting assembly drives the upper mold base 1 and the lower mold base 2 to move away from each other. The side slider 12 gradually returns to its original position under the elastic force of the second elastic element 16. The base body 13 gradually detaches from the sheet metal forming part, and the sliding seat 14 continues to press against the sheet metal forming part under the elastic force of the third elastic element 15 (e.g., Figure 11 (as shown);

[0097] As the base body 13 continues to move away from the sheet metal forming part, under the elastic force of the third elastic element 15, the sliding seat 14 can press against the sheet metal forming part while moving away from the second bending position (moving to the right), thereby separating the sliding seat 14 from the sheet metal forming part, thus completing the bending process (e.g., Figure 12 (As shown).
