Description

Technical Field

[0001] This utility model relates to the field of metal bending technology, and specifically to a metal bending device. Background Technology

[0002] Currently, metal bending tools are typically used to bend metal into the desired shape so that the bent metal can be used in industrial manufacturing (e.g., metal parts).

[0003] In the prior art, the utility model patent with authorization announcement number CN214976916U discloses "A metal bracket bending fixture". The device mainly includes: a base, a protective plate, a servo motor, a rotating shaft, a crankshaft, a connecting rod, a lifting plate, a pressure head, and a bending groove. Among them, the pressure head is fixedly installed at the bottom end of the lifting plate.

[0004] The process of bending metal using the above-mentioned components to drive the pressure head is as follows: First, the servo motor set on the outside of the protective plate drives the rotating shaft to rotate. The rotating shaft rotates through the crankshaft, and the crankshaft can drive the lifting plate to move downward through the connecting rod. The lifting plate drives the pressure head fixedly set below the lifting plate to move downward, thereby realizing the bending of the metal.

[0005] However, when bending metal using the above method, the pressure head located below the lifting plate can only produce bent metal of a single shape after bending the metal.

[0006] Therefore, there is an urgent need for a metal bending device that can expand the shape of the pressure head, so that the shape of the bent metal can be expanded. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a metal bending device. The first and second limiting components allow for the detachable connection of a punching head to a connecting plate. Different shaped punching heads can be used to press metal, resulting in bent metal corresponding to the shape of the punching head. In other words, the punching head is detachably mounted on the connecting plate, allowing for diverse bent metal shapes to meet various industrial production needs.

[0008] This utility model provides a metal bending device, characterized in that it includes: a clamping mechanism for clamping metal; a first driving mechanism fixedly disposed below the clamping mechanism for driving the clamping mechanism to rotate; a first support mechanism disposed on the outer periphery of the clamping mechanism for supporting the first driving mechanism; a bending mechanism disposed above the clamping mechanism for bending the metal downward; a connecting mechanism disposed above the bending mechanism for replacing the bending mechanism; a second driving mechanism fixedly disposed above the connecting mechanism for driving the bending mechanism to move downward; and a second support mechanism disposed on the outer periphery of the second driving mechanism for supporting the second driving mechanism, the second support mechanism being fixedly disposed above the first support mechanism. The clamping mechanism includes a pair of clamping blocks symmetrically arranged on both sides of the metal for clamping the metal; The bending mechanism includes a punch head for bending metal and a mounting plate disposed above the punch head. The connecting mechanism includes a first limiting component fixedly disposed above the mounting plate for limiting the vertical position of the punch head. The first limiting component includes a pair of first limiting screws and a pair of first limiting nuts adapted to the pair of first limiting screws. A connecting plate adapted to the mounting plate is disposed above the first limiting screw. The lower surface of the connecting plate has a mounting groove adapted to the mounting plate. Above the mounting groove, a pair of first U-shaped grooves adapted to the first limiting nuts are formed through the connecting plate. The two ends of the outer wall of the first U-shaped grooves on the connecting plate are fixedly provided with second limiting components for limiting the position of the punch head in the horizontal direction. The second limiting components include a pair of second limiting screws, a limiting plate passing through the outer periphery of the pair of second limiting screws, and a pair of second limiting nuts adapted to the pair of second limiting screws and disposed outside the limiting plate. The aforementioned metal bending device is characterized in that: the first driving mechanism includes a driving disk fixedly disposed below the pair of clamping blocks for driving the pair of clamping blocks to rotate, and a driving motor disposed below the driving disk for driving the driving disk to rotate.

[0009] The aforementioned metal bending device is characterized in that: the first support mechanism includes a base plate fixedly disposed on the outer periphery of the drive motor, and four first support columns disposed below the four corners of the base plate.

[0010] The aforementioned metal bending device is characterized in that: the second driving mechanism includes an electric push rod disposed above the connecting plate for driving the connecting plate to move reciprocally in a linear motion.

[0011] The aforementioned metal bending device is characterized in that: the second support mechanism includes a top plate fixedly disposed above the electric push rod for supporting the electric push rod, and four second support columns fixedly disposed below the four corners of the top plate.

[0012] The beneficial effects are analyzed and reasoned as follows: In the existing technology, when bending metal using the existing method, the pressure head is fixedly set below the lifting plate, which can only produce bent metal of a single shape.

[0013] In the technical solution provided by this utility model, the first limiting component and the second limiting component can detachably connect the stamping head to the connecting plate. After the stamping head of different shapes extrudes the metal, bent metal corresponding to the shape of the stamping head can be obtained. That is, the stamping head is detachably set on the connecting plate, and the bent metal has a variety of shapes, which meets different industrial production needs.

[0014] This avoids the situation in existing solutions where the pressure head is fixed below the lifting plate, resulting in a uniform shape of the bent metal.

[0015] Therefore, by adopting the technical solution of this utility model, the shape of the press head after bending can be expanded, so that the shape of the bent metal can be expanded. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0018] It should be noted that, where there is no conflict, the features of the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the embodiments and accompanying drawings.

[0019] In the existing technology, when bending metal using the existing method, the pressure head set below the lifting plate can only produce bent metal of a single shape after bending the metal.

[0020] Based on this, the present invention provides a metal bending device. The first limiting component and the second limiting component can detachably connect the punch head 2 to the connecting plate 6. After the punch head 2 of different shapes extrudes the metal, bent metal corresponding to the shape of the punch head 2 can be obtained. That is, the punch head is detachably set on the connecting plate 6, and the bent metal has a variety of shapes to meet different industrial production needs.

Figure 6 for Figure 5 A schematic diagram of the explosion structure.

[0022] Combination Figures 1 to 6 The present invention provides a metal bending device, comprising: a clamping mechanism for clamping metal; a first driving mechanism fixedly disposed below the clamping mechanism for driving the clamping mechanism to rotate; a first support mechanism disposed on the outer periphery of the clamping mechanism for supporting the first driving mechanism; a bending mechanism disposed above the clamping mechanism for bending the metal downward; a connecting mechanism disposed above the bending mechanism for replacing the bending mechanism; a second driving mechanism fixedly disposed above the connecting mechanism for driving the bending mechanism to move downward; a second support mechanism disposed on the outer periphery of the second driving mechanism for supporting the second driving mechanism; and the second support mechanism being fixedly disposed above the first support mechanism. The clamping mechanism includes a pair of clamping blocks 1 symmetrically arranged on both sides of the metal for clamping the metal; The bending mechanism includes a punch head 2 for bending metal and a mounting plate 3 disposed above the punch head 2. The connecting mechanism includes a first limiting component fixedly mounted above the mounting plate 3 for limiting the vertical position of the punch head 2. The first limiting component includes a pair of first limiting screws 4 and a pair of first limiting nuts 5 adapted to the pair of first limiting screws 4. A connecting plate 6 adapted to the mounting plate 3 is set above the first limiting screw 4. The lower surface of the connecting plate 6 has a mounting groove adapted to the mounting plate 3. Above the mounting groove, a pair of first U-shaped grooves adapted to the first limiting nut 5 are opened through the connecting plate 6. The two ends of the outer wall of the first U-shaped groove of the connecting plate are fixedly provided with second limiting components for limiting the position of the punch head 2 in the horizontal direction. The second limiting components include a pair of second limiting screws 7, a limiting plate 8 passing through the outer periphery of the pair of second limiting screws 7, and a pair of second limiting nuts 9 adapted to the pair of second limiting screws 7 and set on the outer side of the limiting plate 8. The stamping head 2 is used to bend the metal downwards, causing the metal to take on a shape corresponding to the stamping head 2. For example, the longitudinal sectional view of the stamping head 2 can be U-shaped, conical, etc. The shape of the stamping head 2 described above is only illustrative and not specifically limited.

[0023] In practice, when replacing the punch head 2, firstly, the pair of second limiting nuts 9 passing through the outer side of the limiting plate 8 can be removed. Secondly, while removing the limiting plate 8 passing through the outer periphery of the pair of second limiting screws 7, the punch head 2 can move horizontally. Thirdly, while supporting the punch head 2 from below, while removing the pair of first limiting nuts 5 located above the connecting plate 6, the punch head 2 can move vertically. At this time, the punch head 2 can move freely in both the horizontal and vertical directions, thereby allowing the punch head 2 (or the first limiting screw 4 above the punch head 2) to be removed from the first U-shaped groove.

[0024] Furthermore, the installation process of the stamping heads 2 of different shapes is the reverse process of the above process.

[0025] Specifically, firstly, a pair of first limiting screws 4, which are fixedly set above the next stamping head 2, can be inserted into the first U-shaped groove.

[0026] Next, the first limiting nut 5 is inserted through the upper end of the first limiting screw 4.

[0027] It should be noted that when the mounting plate 3 abuts against the mounting groove on the lower surface of the connecting plate 6, the mounting plate 3 is positioned in the vertical direction, thereby achieving the vertical positioning of the punch head 2 (the mounting plate 3 is fixedly installed above the punch head 2).

[0028] Furthermore, the size of the first limiting nut 5 is larger than the width of the first U-shaped groove. When the first limiting nut 5 is inserted through the outer periphery of the upper end of the first limiting screw 4, the first limiting nut 5 will not fall out of the first U-shaped groove, thus achieving the vertical limiting of the first limiting screw 4, thereby achieving the vertical limiting of the punch head 2 (the mounting plate 3 is fixedly installed below the first limiting screw 4, and the punch head 2 is fixedly installed below the mounting plate 3).

[0029] Third, the limiting plate 8 is inserted into the second limiting screw 7 at the outer end of the connecting plate 6.

[0030] It should be noted that a mounting groove is provided at the bottom of the connecting plate 6, and the dimensions (e.g., length, width, and height) of the mounting groove are adapted to the longitudinal dimensions (e.g., length, width, and height) of the mounting plate 3 and the limiting plate 6 after splicing. That is, after the mounting plate 3 and the limiting plate 6 are installed sequentially from the inner end to the outer end of the mounting groove at the bottom of the connecting plate 6, the mounting plate 3 and the limiting plate 6 are embedded in the mounting groove.

[0031] In other words, when the limiting plate 8 is inserted into the second limiting screw 7, the inner side of the limiting plate 8 abuts against the outer side of the mounting plate 3, thereby limiting the mounting plate 3 in the horizontal direction and thus limiting the punch head 2 (the punch head 2 is fixedly installed below the mounting plate 3) in the horizontal direction.

[0032] Fourth, the second limiting nut 9 is inserted through the outer end of the limiting plate 8 to limit the mounting plate 3 in the horizontal direction, thereby limiting the punch head 2 (the mounting plate 3 is fixedly installed above the punch head 2) in the horizontal direction.

[0033] The beneficial effects are analyzed and reasoned as follows: In the existing technology, when bending metal using the existing method, the pressure head is fixedly set below the lifting plate, which can only produce bent metal of a single shape.

[0034] In the technical solution provided by this utility model, the first limiting component and the second limiting component can detachably connect the stamping head 2 to the connecting plate 6. After the stamping head 2 of different shapes extrudes the metal, bent metal corresponding to the shape of the stamping head 2 can be obtained. That is, the stamping head is detachably set on the connecting plate 6, and the bent metal has a variety of shapes, which meets different industrial production needs.

[0035] This avoids the situation in existing solutions where the pressure head is fixed below the lifting plate, resulting in a uniform shape of the bent metal.

[0036] Therefore, by adopting the technical solution of this utility model, the shape of the press head after bending can be expanded, so that the shape of the bent metal can be expanded.

[0037] In the embodiments described above, a metal bending device was introduced. In another embodiment of this utility model, the specific structure of the first driving mechanism is described.

[0038] For example, the first drive mechanism includes a drive disk 10 fixedly disposed below a pair of clamping blocks 1 for driving the pair of clamping blocks 1 to rotate, and a drive motor 11 disposed below the drive disk 10 for driving the drive disk 10 to rotate.

[0039] In practice, the drive motor 11 can drive the drive disk 10 to rotate, which in turn drives a pair of clamping blocks 1 that are fixedly connected to the drive disk 10 to rotate, thereby adjusting the clamping direction of the pair of clamping blocks 1, that is, adjusting the placement direction of the metal in the clamping blocks 1, so that the stamping head 2 can better bend the metal.

[0040] The specific structure of the first driving mechanism was described in the foregoing embodiments. In another embodiment of this invention, the specific structure of the first supporting mechanism is described.

[0041] For example, the first support mechanism includes a base plate 12 fixedly disposed on the outer periphery of the drive motor 11, and four first support columns 13 disposed at the four corners of the base plate 12.

[0042] In the specific implementation, four first support columns 13 are set below the base plate 12 to provide strong support for the drive motor 11 fixedly installed in the base plate 12, so that the drive motor 11 can adjust the clamping direction of a pair of clamping blocks 1.

[0043] The specific structure of the first support mechanism was described in the foregoing embodiments. In another embodiment of this invention, the specific structure of the second drive mechanism is described.

[0044] For example, the second drive mechanism includes an electric push rod 14 disposed above the connecting plate 6 for driving the connecting plate 6 to move linearly up and down.

[0045] In practice, the electric push rod 14 can drive the connecting plate 6 to move up and down, so as to bend the metal below the stamping head 2.

[0046] The specific structure of the second driving mechanism was described in the foregoing embodiments. In another embodiment of this invention, the specific structure of the second supporting mechanism is described.

[0047] For example, the second support mechanism includes a top plate 15 fixedly disposed above the electric push rod 14 for supporting the electric push rod 14, and four second support columns 16 fixedly disposed below the four corners of the top plate 15.

[0048] In practice, four second support columns 16 are provided below the top plate 15 to provide strong support for the electric push rod 14 fixedly installed below the top plate 15, so that the electric push rod 14 can drive the stamping head 2 to move up and down.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
