Description

Technical Field

[0001] The utility model relates to the technical field of stamping and forming, in particular to a forming device. Background Art

[0002] In the process of hot forging metal, the metal blank is first heated to a certain temperature, and then pressure is applied through the forming stamping die to deform the metal blank to form a specific shape and size, so that it can be made into a metal product. For U-shaped metal blanks with irregular cross-sections, the traditional process requires the use of a bending die to bend the metal blank into a U shape, and then the return die is used to form the characteristic structure at both ends of the U-shaped metal blank. However, this process requires the metal blank to undergo two positioning and forming processes, which not only increases the forming process, but also easily leads to positioning errors, affecting the dimensional accuracy of the metal product, and thus resulting in low forming accuracy.

[0091] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0092] See also Figure 1 An embodiment of the present application provides a forming device 100, which includes a positioning component 101 for positioning a workpiece and a pressing component 102 movably disposed on the positioning component 101. The forming device 100 of the present application can complete the bending operation and the forming operation of the workpiece at one time, thereby improving the forming accuracy.

[0093] To facilitate understanding and explanation of the embodiments of the present application, a three-dimensional coordinate system is established in some of the drawings, with the Z-axis direction being the first direction, the X-axis direction being the second direction, and the Y-axis direction being the third direction, and the X-axis direction, the Y-axis direction and the Z-axis direction being perpendicular to each other.

[0094] See also Figure 1 and Figure 2The positioning assembly 101 includes a fixing member 10 arranged opposite to the pressing assembly 102 along the Z-axis direction, a bearing member 20 movably inserted into the fixing member 10, two positioning members 30 arranged at intervals along the X-axis direction, two pushing members 40 respectively inclined against the two positioning members 30, and two limiting members 50 arranged one by one corresponding to the two pushing members 40. The fixing member 10 is generally a plate-shaped structure. The fixing member 10 and the pressing assembly 102 are arranged opposite to each other along the Z-axis direction. The bearing member 20 is movably inserted into the fixing member 10 along the Z-axis direction and carries the workpiece. The two positioning members 30 are arranged at opposite sides of the bearing member 20 along the X-axis direction and are both slidably connected to the fixing member 10. The two positioning members 30 position the workpiece, and each positioning member 30 is provided with a molding groove 31 on one side facing the bearing member 20. The two pushing members 40 are installed on both sides of the two positioning members 30 along the X-axis direction and are respectively inclined against the corresponding positioning members 30. The two limiting members 50 are both roughly block-shaped, and are both connected to the fixing member 10. The two limiting members 50 and the corresponding positioning members 30 are located on opposite sides of the two pushing members 40 along the X-axis direction, and each limiting member 50 is provided with a limiting groove 51 on one side facing the corresponding pushing member 40 to receive the corresponding part of the pushing member 40 and limit the movement direction of the corresponding pushing member 40. Exemplarily, the groove shape of the forming groove 31 is semi-arc-shaped.

[0095] In this way, the two pushers 40 are respectively in contact with the corresponding inclined surfaces of the positioning members 30, so that the two pushers 40 can push the two positioning members 30 to move relative to each other along the X-axis direction under the action of the pressing assembly 102, so that the two positioning members 30 bend the workpiece to a preset shape. In addition, a molding groove 31 is provided on the positioning member 30. When the pressing assembly 102 applies force to the workpiece carried by the carrier 20, the workpiece is pressed into the molding groove 31 under the action of the pressing assembly 102, so that the workpiece is bent to a preset shape under the restriction of the molding groove 31, which is conducive to improving the molding accuracy of the workpiece. In addition, by setting the above-mentioned two limiters 50, the two limiters 50 limit the two pushers 40 to always move along the Z-axis direction, so that the two pushers 40 can stably push the two positioning members 30 to move relative to each other along the X-axis direction, thereby improving the molding stability.

[0096] See also Figure 2 The fixing member 10 is provided with a receiving groove 11 and two receiving grooves 12 respectively located on both sides of the receiving groove 11 along the X-axis direction. The receiving groove 11 matches the bearing member 20 and is located between the two positioning members 30. The two receiving grooves 12 respectively match the two pushing members 40. The notch of the receiving groove 11 and the notches of the two receiving grooves 12 are both arranged on the side of the fixing member 10 facing the pressing component 102.

[0097] See also Figure 1 and Figure 2The carrier 20 includes a carrier 21 movably inserted in the fixing member 10 and a first elastic body 22 elastically supporting the carrier 21. The carrier 21 is generally a block structure. The carrier 21 is movably inserted in the storage groove 11 along the Z-axis direction and supports the workpiece. The carrier 21 and the two positioning members 30 are clearance-matched along the X-axis direction. The elastic force direction of the first elastic body 22 is parallel to the Z-axis direction. The two ends of the first elastic body 22 are elastically supported on the bottom of the storage groove 11 and the carrier 21. Exemplarily, the first elastic body 22 is a spring.

[0098] In this way, the carrier 21 and the two positioning members 30 are arranged to be clearance-matched along the X-axis direction, so that the carrier 21 and the two positioning members 30 have a sufficiently large movable space in the X-axis direction, and the two positioning members 30 are prevented from interfering with the carrier 21 when the two positioning members 30 move relative to each other along the X-axis direction, thereby ensuring the stable operation of the positioning members 30. In addition, by providing the above-mentioned first elastic body 22, when the pressing assembly 102 applies a pressing force to the workpiece carried by the carrier 21, the carrier 21 compresses the first elastic body 22 to the bottom of the receiving groove 11. When the workpiece is formed, the pressing assembly 102 cancels the application of the pressing force to the carrier 21, and the compressed first elastic body 22 provides elastic force to drive the carrier 21 to push the formed workpiece to move away from the fixing member 10 along the Z-axis direction, and drives the carrier 21 to return to the initial position, so that the molding device 100 can repeat the molding operation.

[0099] See also Figure 2 The positioning member 30 includes a bending body 32 slidably connected to the fixing member 10, a positioning body 33 connected to the bending body 32, and a rotating body 34 rotatably connected to the bending body 32. The bending body 32 is roughly a block structure, the bending body 32 is located between the bearing member 20 and the corresponding pushing member 40 along the X-axis direction, and is slidably connected to the fixing member 10, and the forming groove 31 is opened on the side of the bending body 32 facing the bearing member 20. The positioning body 33 is roughly a block structure, the positioning body 33 is connected to one end of the bending body 32 facing the pressing component 102 and is provided with a positioning groove 331 for positioning the workpiece. The rotating body 34 is roughly a rod-shaped structure, the rotating body 34 is arranged in the forming groove 31 and adjacent to the positioning body 33, and the rotating body 34 is rotatably connected to the bending body 32, and the rotating body 34 rolls in contact with the workpiece when the bending body 32 is bent. Exemplarily, the groove shape of the positioning groove 331 is U-shaped.

[0100] In this way, by setting the above-mentioned positioning body 33, the two positioning bodies 33 position the opposite ends of the workpiece through the positioning groove 331 before the workpiece is bent, so that the workpiece to be bent maintains a preset placement position and a preset orientation on the carrier 21, so that the pressing component 102 stably applies a pressing force to the workpiece of the carrier 21, so that the workpiece is stably pressed into the forming groove 31 of the bending body 32, and then the workpiece is stably bent into a preset shape, thereby improving the forming accuracy of the workpiece. In addition, by setting the above-mentioned rotating body 34, when the two bending bodies 32 relatively move along the X-axis direction to bend the workpiece, the workpiece can form a rolling contact between the rotating body 34 in the forming groove 31, thereby reducing damage to the workpiece and improving the quality of the workpiece.

[0101] Please continue reading Figure 2 The pusher 40 includes a pusher 41 whose inclined surface abuts against the corresponding positioning member 30 and a second elastic body 42 elastically abutting against the pusher 41. The pusher 41 is generally block-shaped and is movably arranged in the receiving groove 12 along the Z-axis direction. The elastic force direction of the second elastic body 42 is parallel to the Z-axis direction. The two ends of the second elastic body 42 elastically abut against the bottom of the receiving groove 12 and the pusher 41. Exemplarily, the second elastic body 42 is a spring.

[0102] In this way, by setting the above-mentioned pushing member 40, when the pressing component 102 moves close to the fixing member 10, the pressing component 102 applies a force to the pushing body 41, so that the pushing body 41 pushes the positioning member 30 abutting against its inclined surface to move along the X-axis direction, and compresses the second elastic body 42 to the bottom of the accommodating groove 12. When the pressing component 102 moves away from the fixing member 10, the pressing component 102 cancels the application of force to the pushing body 41, so that the compressed second elastic body 42 provides elastic drive, thereby the pushing body 41 is reset to the initial position, so that the pushing member 40 can repeatedly push the corresponding positioning member 30 to bend the workpiece, thereby realizing repeated bending operations on the workpiece.

[0103] See also Figure 1 The pressing component 102 is arranged opposite to the positioning component 101 along the Z-axis direction and is movably arranged above the positioning component 101. The pressing component 102 includes a movable part 60 corresponding to the fixed part 10, two pressing parts 70 connected to the movable part 60, two pushing parts 80 arranged in a one-to-one correspondence with the two pushing parts 40, and two forming parts 90 arranged in a one-to-one correspondence with the two forming grooves 31. The movable part 60 is movably arranged above the fixed part 10 and corresponds to the fixed part 10. The two pressing parts 70 are arranged at intervals along the X-axis direction and both correspond to the bearing part 20, and the two pressing parts 70 are movably connected to the movable part 60, the two pushing parts 80 are respectively arranged in a one-to-one correspondence with the two pushing parts 40, the two pushing parts 80 are both connected to the movable part 60, and the two forming parts 90 are respectively arranged in a one-to-one correspondence with the two forming grooves 31 and are both movably connected to the movable part 60.

[0104] In this way, by setting the specific structure of the above-mentioned pressing assembly 102, when the two positioning members 30 position the opposite ends of the workpiece, the movable member 60 first drives the two pressing members 70 and the two pushing members 80 to move a first distance close to the supporting member 20, and the two pressing members 70 press the workpiece into the forming groove 31 and push the supporting member 20 to shrink to the fixed member 10, and the two pressing members 70 press the two pushing members 40 to push the two positioning members 30 to move relative to each other, so as to achieve bending the workpiece to a preset shape, and then the movable member 60 drives the forming member 90 to continue to move close to the supporting member 20 and move a second distance, and the two forming members 90 are respectively extended into the corresponding forming grooves 31 under the support of the corresponding positioning members 30, so as to respectively form the two ends of the bent workpiece into the preset structure, thereby achieving one-time completion of the bending operation and the forming operation of the workpiece, without the need to use the bending mold and the return mold for the bending operation and the forming operation in succession, which causes errors in the workpiece after forming, thereby improving the forming accuracy of the workpiece.

[0105] See also Figure 1 and Figure 3 The movable member 60 includes a movable body 61 corresponding to the fixed member 10, a guide body 62 connected to the movable body 61, and two placement bodies 63 arranged at intervals along the X-axis direction. The movable body 61 is generally in a plate-like structure. The movable body 61 and the fixed member 10 are arranged opposite to each other along the Z-axis direction. The pressing member 70 is movably connected to the movable body 61, and two push members 80 are connected to the movable member 60. The guide body 62 is generally in a long plate-like structure. The guide body 62 is connected to the movable body 61 and is provided with a guide groove 621. The guide groove 621 is opened on the side of the guide body 62 facing the pressing member 70. The guide groove 621 receives part of the pressing member 70 and guides the pressing member 70. The two placement bodies 63 are generally in a block-like structure. The two placement bodies 63 are respectively arranged in one-to-one correspondence with the two forming members 90 and are both connected to the movable body 61. Each placement body 63 is provided with an arc groove 631 on the side facing the fixed member 10. The arc groove 631 accommodates the corresponding forming member 90.

[0106] In this way, the movable body 61 is movably connected with the pressing member 70, and the movable body 61 is connected with the two pushing members. The movable body 61 drives the two pressing members 70 and the two pushing members to move synchronously along the Z-axis direction close to the fixed member 10, so that the two pressing members 70 stably apply a pressing force to the workpiece carried by the carrier 21, and at the same time, the two pushing members push the two pushing members 40 respectively along the Z-axis direction, so that the two positioning members 30 move relatively along the X-axis direction under the pushing of the corresponding pushing members 40, which is conducive to ensuring that the forming device 100 stably bends the workpiece to a preset shape, thereby improving the forming stability of the workpiece. In addition, the guide groove 621 accommodates part of the pressing member 70, and the guide groove 621 guides the movement direction of the pressing member 70, so that the pressing member 70 stably presses the workpiece carried by the carrier 21, further improving the bending stability of the workpiece. In addition, the two placement bodies 63 respectively accommodate the corresponding molded parts 90, which is beneficial to the reasonable layout of the movable part 60 and the molded part 90 and simplifies the mechanical structure of the pressing assembly 102.

[0107] See also Figure 3 and Figure 4 , a supporting groove 622 is provided at one end of the guide body 62 away from the fixed member 10, and the supporting groove 622 is away from the fixed member 10 relative to the guide groove 621 along the Z-axis direction. The pressing member 70 includes a pressing body 71 movably arranged in the movable body 61, a sliding body 72 connected to the pressing body 71, a third elastic body 73 elastically supporting the pressing body 71, and a limiting body 74 arranged on the same side of the pressing body 71 as the sliding body 72. The pressing body 71 is generally a long rod-shaped structure, and the pressing body 71 is movably arranged in the movable body 61 along the Z-axis direction and presses the workpiece. The sliding body 72 is generally a long strip-shaped structure, and the sliding body 72 is slidably arranged in the guide groove 621 and connected to the pressing body 71. The sliding body 72 slides in the guide groove 621 to guide the pressing body 71. The elastic force of the third elastic body 73 is parallel to the Z-axis direction, and the two ends of the third elastic body 73 elastically support the placement body 63 and the pressing body 71 respectively. The limiting body 74 is generally a block-shaped structure, and the limiting body 74 and the sliding body 72 are arranged on the same side of the pressing body 71 and connected to the pressing body 71. The limiting body 74 is away from the fixing member 10 relative to the sliding body 72, and the limiting body 74 extends into the abutting groove 622, and when the movable body 61 moves away from the fixing member 10, it abuts against the bottom of the abutting groove 622 to limit the movement distance of the pressing body 71. Exemplarily, the third elastic body 73 is a spring.

[0108] In this way, by setting the specific structure of the pressing member 70, when the movable body 61 drives the pressing body 71 to move close to the carrier 21 along the Z-axis direction, the sliding body 72 slides in the guide groove 621 to guide the pressing body 71 to accurately move close to the workpiece carried by the carrier 21, so that the pressing body 71 stably presses the workpiece into the forming groove 31 to achieve bending the workpiece into a preset shape. At the same time, the pressing body 71 compresses the third elastic body 73 to the placement body 63 along the Z-axis direction under the support of the workpiece, so that the pressing body 71 flexibly presses the workpiece to prevent the workpiece from being subjected to excessive When the movable body 61 drives the pressing body 71 to move away from the supporting body 21 along the Z-axis direction, the pressing member 70 and the workpiece are loosened from each other, and the compressed third elastic body 73 provides elastic force and drives the pressing body 71 to drive the limiting body 74 to move close to the supporting body 21, and the limiting body 74 is supported by the bottom of the supporting groove 622 to limit the movement distance of the pressing body 71, so that the pressing body 71 can be stably reset to the initial position after the operation is completed, avoiding the pressing body 71 from moving too far and separating from the movable body 61, so as to facilitate the pressing member 70 to repeat the pressing operation.

[0109] See also Figure 3 The two forming members 90 each include a supporting body 91 movably disposed in the movable body 61, a rotating body 92 rotatably disposed in the arc groove 631, and a forming body 93 connected to the rotating body 92. The supporting body 91 is disposed opposite to the corresponding positioning member 30 along the Z-axis direction and movably penetrates the movable body 61 along the Z-axis direction, the rotating body 92 is rotatably disposed in the arc groove 631 and connected to the supporting body 91, the forming body 93 matches the corresponding forming groove 31 and is connected to the rotating body 92, and the distance between the supporting body 91 and the corresponding positioning member 30 is greater than the distance between the pushing member 80 and the corresponding pushing member 40.

[0110] In this way, the distance between the supporting body 91 and the corresponding positioning member 30 is set to be larger than the distance between the pushing member 80 and the corresponding pushing member 40. When the movable body 61 moves toward the fixed member 10 along the Z-axis direction, when the pushing member 80 abuts against the corresponding pushing member 40, the supporting body 91 and the corresponding positioning member 30 still have a certain movable gap, so that the supporting body 91 can abut against the corresponding positioning member 30 after the workpiece is bent and drive the rotating body 92 to rotate, so that the forming body 93 is driven by the rotating body 92 to extend into the corresponding forming groove 31 and form the end of the bent workpiece into a preset structure, thereby ensuring that the forming device 100 first bends the workpiece into a preset shape, and then forms the two ends of the bent workpiece into a preset structure, which is conducive to maintaining the operating step sequence of the forming device 100.

[0111] Please continue reading Figure 3The rotating body 92 includes an arc-shaped rotating part 921 rotatably arranged in the arc-shaped groove 631 and two first elastic parts 922 elastically resisting the arc-shaped rotating part 921. The arc-shaped rotating part 921 is roughly a columnar structure with a semicircular cross-section. The arc-shaped rotating part 921 is rotatably arranged in the arc-shaped groove 631 and is respectively connected to the resisting body 91 and the forming body 93. The two first elastic parts 922 are arranged at intervals along the Y-axis direction, and the elastic force direction of each first elastic part 922 is parallel to the Z-axis direction. Each first elastic part 922 is connected to the bottom of the arc-shaped groove 631 and elastically resists the arc-shaped rotating part 921. Exemplarily, the first elastic part 922 is a spring.

[0112] In this way, by setting the specific structure of the rotating body 92, when the arc-shaped rotating part 921 rotates along the preset direction under the support of the supporting body 91, the arc-shaped rotating part 921 compresses the first elastic part 922 to the placement body 63, so that the forming body 93 is driven by the arc-shaped rotating part 921 to extend into the corresponding forming groove 31. When the forming body 93 completes the forming operation of the workpiece, the supporting body 91 and the corresponding positioning member 30 are loosened from each other, and the compressed first elastic part 922 provides elastic force to drive the arc-shaped rotating part 921 to rotate in a direction opposite to the preset direction, so that the arc-shaped rotating part 921 drives the supporting body 91 and the forming body 93 to return to the initial position, which is convenient for repeating the forming operation.

[0113] It can be understood that the above-mentioned preset direction can be clockwise or counterclockwise. The cross section of the arc-shaped rotating part 921 along the X-axis direction includes an arc-shaped side and a curved side. The arc length of the semicircle with the same center and the same radius corresponding to the arc-shaped side is the preset arc length. The arc length of the arc-shaped side is the first arc length. The arc length of the arc-shaped groove 631 is the second arc length. The first arc length is less than or equal to the second arc length, and the first arc length is greater than the preset arc length, so as to ensure that the arc-shaped groove 631 provides support force for the arc-shaped rotating part 921 along the X-axis direction, prevent the arc-shaped rotating part 921 from falling from the arc-shaped groove 631 during the rotation process, and then make the arc-shaped rotating part 921 stably rotate in the arc-shaped groove 631.

[0114] See also Figure 1 and Figure 3The movable body 61 is provided with a receiving groove 611, and the receiving groove 611 matches the supporting body 91. The supporting body 91 includes a supporting portion 911 movably penetrated in the movable body 61 and a linkage portion 912 connected to the arc-shaped rotating portion 921. The supporting portion 911 is roughly a rod-shaped structure. The supporting portion 911 and the corresponding positioning member 30 are arranged opposite to each other along the Z-axis direction. The supporting portion 911 is movably penetrated in the movable body 61 along the Z-axis direction and penetrates into the receiving groove 611. The linkage portion 912 is roughly a long plate-shaped structure. The linkage portion 912 is arranged in the receiving groove 611. One end of the linkage portion 912 is connected to the supporting portion 911, and the other end of the linkage portion 912 is connected to the rotating body 92. When the movable body 61 moves away from the fixed member 10, the linkage portion 912 abuts against the bottom of the receiving groove 611 to limit the movement distance of the supporting portion 911.

[0115] In this way, by setting the specific structure of the above-mentioned supporting body 91, when the supporting part 911 drives the linkage part 912 to move close to the corresponding placement body 63 along the Z-axis direction under the support of the corresponding positioning member 30, the arc-shaped rotating part 921 rotates in the arc groove 631 along the preset direction under the drive of the linkage part 912, so that the forming body 93 extends into the forming groove 31 under the drive of the rotating body 92 and forms the bent workpiece into a preset structure, thereby realizing the forming operation of the end of the workpiece. When the supporting part 911 is loosened from the corresponding positioning member 30 after the workpiece completes the forming operation, the arc-shaped rotating part 921 rotates in the arc groove 631 along the direction opposite to the preset direction, so that the linkage part 912 drives the supporting part 911 to move away from the corresponding placement body 63 under the drive of the arc-shaped rotating part 921, and abuts against the bottom of the accommodating groove 611 to limit the movement distance of the supporting part 911, so that the supporting part 911 is reset to the initial position, which is convenient for the supporting body 91 to repeat the supporting operation.

[0116] See also Figure 3 The forming body 93 includes a connecting portion 931 connected to the rotating body 92, two second elastic portions 932 elastically abutting against the connecting portion 931, and a forming portion 933 connected to the connecting portion 931. The connecting portion 931 is generally a block-shaped structure, and the connecting portion 931 is connected to the rotating body 92. The two second elastic portions 932 are arranged at intervals along the Y-axis direction, and the elastic force direction of each second elastic portion 932 is parallel to the Z-axis direction. The two ends of each second elastic portion 932 elastically abut against the connecting portion 931 and the movable body 61, respectively. The forming portion 933 is generally a rod-shaped structure. The forming portion 933 is located between the two second elastic portions 932 along the Y-axis direction and is connected to the connecting portion 931. One end of the forming portion 933 away from the connecting portion 931 is movably inserted into the movable body 61 and forms the end of the workpiece into a preset structure. Exemplarily, the second elastic portion 932 is a spring.

[0117] In this way, by setting the specific structure of the above-mentioned forming body 93, when the workpiece is formed, the connecting part 931 moves close to the fixing part 10 under the drive of the arc-shaped rotating part 921, and compresses the second elastic part 932 to the movable body 61. The forming part 933 extends into the corresponding forming groove 31 under the drive of the connecting part 931 to form the end of the bent workpiece into a preset structure. After the workpiece is formed into the preset structure, the compressed second elastic part 932 provides elastic force and drives the arc-shaped rotating part 921 and the connecting part 931 to return to the initial position, so that the forming body 93 can repeat the forming operation.

[0118] The working process of the above-mentioned molding device 100 is roughly as follows:

[0119] First, the carrier 20 carries the workpiece, and the two positioning members 30 position the workpiece through the positioning grooves 331, so that the workpiece maintains a preset orientation and placement position on the carrier 20, so that the pressing member 70 corresponds to the position to be pressed on the workpiece;

[0120] Then, the movable member 60 drives the pressing member 70 and the two pushing members 80 to move close to the carrier 20 by a first distance, the pressing member 70 presses the workpiece into the forming groove 31 and pushes the carrier 20 to shrink to the fixed member 10, and the two pressing members 70 press the two pushing members 40 to move along the Z-axis direction, so that the two pushing members 40 push the two positioning members 30 to move relative to each other along the X-axis direction, so as to realize bending the workpiece into a preset shape;

[0121] Finally, the movable part 60 drives the two abutting bodies 91 to continue to move closer to the supporting part 20 and move a second distance. The two abutting bodies 91 move away from the fixed part 10 along the Z-axis direction under the abutment of the corresponding positioning parts 30, so that the rotating body 92 rotates along the preset direction in the arc groove 631, so that the forming body 93 is driven by the rotating body 92 to extend into the corresponding forming groove 31, so that the two ends of the bent workpiece are respectively formed into the preset structure, thereby completing the bending operation and the forming operation of the workpiece at one time, without using the bending mold and the return mold for the bending operation and the forming operation successively, which causes errors in the workpiece after forming, thereby improving the forming accuracy.

[0122] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
