Description

Technical Field

[0001] This invention relates to the field of mechanical bending technology, and in particular to a bending and pressing device. Background Technology

[0002] The bending and pressing process is widely used in the production and processing of workpieces. For example, in the processing of a hard drive enclosure shell, there is a bending and pressing process that involves bending and pressing the snap-fit ​​points on the shell. Specifically, the hard drive enclosure shell includes a cover plate and a frame. The cover plate can be placed on the frame. The frame has snap-fit ​​openings, and the cover plate has snap-fit ​​points. The snap-fit ​​points pass through the snap-fit ​​openings and are partially exposed. By bending and pressing, the snap-fit ​​points are bent and fastened to the frame, thus assembling and fixing the cover plate and the frame to form the shell. Commonly, the bending and pressing of snap-fit ​​points is done manually. On the one hand, this results in high labor costs in workpiece production; on the other hand, manual bending and pressing of workpieces has low production efficiency and can lead to unstable bending and pressing quality of the shell.

[0036] This invention proposes a bending and pressing device 100.

[0037] Please refer to Figure 1 or Figure 5 In some embodiments of the bending and pressing device 100, the bending and pressing device 100 includes:

[0038] Machine body 10, wherein the machine body 10 is provided with a fixture seat 20, wherein a receiving cavity is formed within the fixture seat 20 for receiving a workpiece; and

[0039] A bending and pressing device 30 is provided on the machine body 10 and located on the periphery of the fixture seat 20. The bending and pressing device 30 has a bending and pressing head 322 facing the fixture seat 20. The bending and pressing head 322 can move towards the fixture seat 20 and is used to press against the outer side of the workpiece inside the fixture seat 20 to bend and press the fastener of the workpiece.

[0040] In this embodiment, the bending and pressing device 100 includes a body 10 and a bending and pressing device 30. The body 10 is provided with a fixture seat 20, and a receiving cavity is formed in the fixture seat 20, in which the workpiece is confined. The bending and pressing device 30 is provided on the body 10 and located on the periphery of the fixture seat 20. The bending and pressing device 30 is provided with a bending and pressing head 322 facing the fixture seat 20. The bending and pressing head 322 can move from the outside of the fixture seat 20 toward the inside of the fixture seat 20 to press against the outside of the workpiece inside the fixture seat 20, so as to bend and press the fastening point of the workpiece.

[0041] In some embodiments, the contact surface 322c of the bending head 322 can be inclined relative to the bending surface of the workpiece buckle in the following embodiment. With this configuration, when the bending head 322 moves toward the fixture seat 20 and presses against the workpiece buckle, the contact surface 322c of the bending head 322 can apply a bending pressure that is inclined downward toward the fixture seat 20 from the end away from the fixture seat 20, so as to facilitate the bending head 322 bending the workpiece buckle.

[0042] It should be noted that the bending and pressing process is widely used in the production and processing of workpieces. For example, in the processing of a hard drive enclosure shell, there is a bending and pressing process for the shell's fastening points. Specifically, the hard drive enclosure shell includes a cover plate and a frame. The cover plate can be placed on the frame. The frame has fastening openings, and the cover plate has fastening points. The fastening points pass through the fastening openings and are partially exposed. By bending and pressing, the fastening points are bent and fastened to the frame, thus assembling and fixing the cover plate and frame to form the shell. Commonly, the bending and pressing of fastening points is done manually. On the one hand, this results in high labor costs in workpiece production; on the other hand, manual bending and pressing of workpieces has low production efficiency and can lead to unstable bending and pressing quality of the shell.

[0043] Therefore, it can be understood that the technical solution of the present invention is provided with a fixture seat 20 for mounting the workpiece and a bending mechanism 32 located on the periphery of the fixture seat 20. The bending mechanism 32 is provided with a bending head 322 on the side facing the fixture seat 20. The bending head 322 can move toward the workpiece in the fixture seat 20 to press and bend the buckle on the workpiece. This can automatically complete the bending process of the workpiece, thereby improving the bending efficiency of the bending device 100 and ensuring the bending quality of the workpiece.

[0044] Please refer to Figures 1 to 3 In some embodiments of the bending and pressing device 100, the bending and pressing device 30 includes:

[0045] A base 31, wherein the base 31 is disposed on the body 10 and located on one side of the fixture base 20; and

[0046] The bending and pressing mechanism 32 includes a driving component 321 and a bending and pressing head 322. The driving component 321 is disposed on the base 31, and the bending and pressing head 322 is disposed at the output end of the driving component 321 facing the fixture seat 20, so as to move toward the fixture seat 20 under the drive of the output end.

[0047] In this embodiment, the bending and pressing device 30 includes a base 31 and a bending and pressing mechanism 32. The base 31 is disposed on the machine body 10 and located on one side of the fixture seat 20. The bending and pressing mechanism 32 includes a driving component 321 and a bending and pressing head 322. The driving component 321 is disposed on the base 31, and the bending and pressing head 322 is disposed at the output end of the driving component 321 facing the fixture seat 20, so as to move towards the fixture seat 20 under the drive of the output end.

[0048] Specifically, the drive assembly 321 includes a drive member and a power output member. The power output member is located on the side of the drive member facing the fixture seat 20 and can move toward or away from the fixture seat 20 under the drive of the drive member, so as to drive the bending pressure head 322 located on the power output member to move toward or away from the fixture seat 20. The drive member can be, but is not limited to, a motor or a cylinder. The specific implementation can be set according to actual needs and is not limited here.

[0049] In some embodiments, a buffer may be provided on the drive assembly 321, which can reduce the impact force of the bending head 322 during the bending process, thereby improving the stability of the bending device 30 during the bending process.

[0050] Please refer to Figure 3 In some embodiments of the invention bending device 100, the top of the base 31 is provided with an inclined surface, which is inclined downward from the end away from the fixture seat 20 toward the fixture seat 20, and the drive assembly 321 is provided on the inclined surface and extends along the inclined direction of the inclined surface.

[0051] In this embodiment, the top of the base 31 is provided with an inclined surface. The inclined surface is inclined downward from the end away from the fixture seat 20 toward the fixture seat 20. The drive component 321 is provided on the inclined surface and extends along the inclined direction of the inclined surface. With this configuration, the drive component 321 can drive the bending head 322 to move toward the workpiece in the fixture seat 20 along the inclined direction of the inclined surface, so that the bending head 322 applies a bending force to the fastening point of the workpiece from the outside of the workpiece to the inside of the workpiece and inclined downward, so that the bending head 322 pushes the fastening point of the workpiece to bend into the body of the workpiece.

[0052] Please refer to Figure 4 In some embodiments of the bending and pressing device 100, the bending and pressing head 322 includes:

[0053] The main body 322a is driveably connected to the drive assembly 321, and moves toward the fixture seat 20 under the drive of the output end; and

[0054] Rotating part 322b is rotatably disposed at one end of the main body 322a facing the fixture seat 20, and the rotating part 322b has an abutment surface 322c facing the workpiece;

[0055] The rotating part 322b has an initial position and a pressing position. When the rotating part 322b is in the initial position, the abutting surface 322c is inclined to press against the fastening point of the workpiece. When the rotating part 322b is in the pressing position, the abutting surface 322c is horizontal to press against the fastening point of the workpiece.

[0056] In this embodiment, the bending pressure head 322 can move toward the workpiece in the fixture seat 20 along the inclined direction of the inclined surface under the drive of the drive assembly 321. The bending pressure head 322 includes a main body 322a and a rotating part 322b. The main body 322a is tractively connected to the drive assembly 321 so as to move toward the fixture seat 20 under the drive of the output end of the drive assembly 321. The rotating part 322b is rotatably disposed at one end of the main body 322a toward the fixture seat 20, and the rotating part 322b has an abutment surface 322c toward the workpiece.

[0057] The bending head 322 can move in two stages toward the fixture seat 20 to complete the bending process of the workpiece's fastening points. First, the rotating part 322b can move toward the fixture seat 20 together with the main body 322a under the drive of the output end. At this time, the rotating part 322b connected to the main body 322a is in the initial position, and the abutting surface 322c of the rotating part 322b is inclined relative to the workpiece's fastening points to press them against the workpiece's fastening points, so that the workpiece's fastening points are initially bent relative to the workpiece's main body. Further, when the main body 322a moves toward the fixture seat 20 to the limit position, the rotating part 322b can also rotate relative to the main body 322a from the initial position to the pressing position, so that the abutting surface 322c of the rotating part 322b moves further toward the workpiece's fastening points to press them horizontally onto the workpiece's fastening points, so that the workpiece's fastening points are further flattened onto the workpiece's main body. This configuration, by enabling the bending head 322 to move in two stages, allows the bending head 322 to achieve a better bending effect on the workpiece, thereby improving the practicality of the bending equipment 100.

[0058] Specifically, in some embodiments, the main body 322a has an inwardly formed mounting cavity on the side facing the fixture seat 20; the rotating part 322b is a movably arranged fan-shaped slider, the outer side of which has an abutment surface 322c, and the end of the fan-shaped slider near its center is hinged to the main body 322a; the main body 322a has a push assembly in the mounting cavity, the push assembly extends along the length of the main body 322a, the output end of the push assembly is connected to the end of the fan-shaped slider away from its center on the inner side, and can extend and retract toward the fixture seat 20 to drive the rotating part 322b to switch between the initial position and the pressing position. When the output end of the push assembly moves toward the fixture seat 20, the output end can push the rotating part 322b to drive the rotating part 322b to flip outward from the mounting cavity, so that the abutting surface 322c of the rotating part 322b can move further toward the fastening point of the workpiece. When the output end of the push assembly moves away from the fixture seat, it can drive the rotating part 322b to rotate to the initial position and be re-accommodated in the mounting cavity.

[0059] Of course, the technical solution of the present invention is not limited to this. In another feasible embodiment, a gear drive assembly is provided in the mounting cavity of the main body 322a, and the rotating part 322b has a rotating shaft, which is rotatably disposed in the mounting cavity. The rotating part 322b can rotate relative to the main body 322a around the central axis of the rotating shaft, so that the rotating part 322b rotates out of or back into the mounting cavity. The rotating shaft of the rotating part 322b is driven by an input gear, which meshes with the gear drive assembly. With this arrangement, the gear drive assembly can drive the input gear to rotate forward, causing the input gear to rotate the rotating part 322b outward from the mounting cavity relative to the main body 322a to the pressing position. The gear drive assembly can also drive the input gear to rotate in reverse, causing the input gear to rotate the rotating part 322b back to the initial position, so that it can be housed in the mounting cavity of the main body 322a. This allows the contact surface 322c of the rotating part 322a to rotate towards or away from the workpiece. Specific embodiments can be set according to actual needs and are not limited here.

[0060] Furthermore, in some embodiments, the contact surface 322c of the bending head 322 is contoured to the fastening point of the workpiece. With this configuration, the bending head 322 can avoid other structures on the main body of the workpiece, such as limiting protrusions, during the bending process. This avoids additional interference to the bending head 322 during bending, allowing the bending head 322 to flatten and press the fastening point of the workpiece onto the main body of the workpiece. This further improves the applicability and bending effect of the bending device 100.

[0061] Please refer to Figure 2 or Figure 3In some embodiments of the bending and pressing device 100, the side wall of the fixture seat 20 is provided with a relief groove 21 that passes through the accommodating cavity. The relief groove 21 is provided corresponding to the fastening point of the workpiece. The bending and pressing head 322 can pass through the relief groove 21 and move toward the workpiece to bend and press the fastening point of the workpiece.

[0062] In this embodiment, the side wall of the fixture seat 20 is provided with a relief groove 21 that passes through the accommodating cavity. The relief groove 21 is set with the fastening point of the workpiece. The bending pressure head 322 can move toward the workpiece through the relief groove 21 to bend the fastening point of the workpiece. Through the guiding effect of the relief groove 21 on the bending pressure head 322, the precise alignment between the bending pressure head 322 and the fastening point of the workpiece can be achieved, so as to improve the bending effect of the bending device 30.

[0063] Specifically, the fixture base 20 includes a bottom wall and a side wall circumferentially arranged along the bottom wall. The clearance groove 21 extends from the inner side of the side wall to the top side of the side wall, so that the bending pressure head 322 can be inclined downward from the end away from the fixture base 20 and pass into the clearance groove 21, thereby corresponding to the buckle point of the workpiece in the fixture base 20. In some embodiments, the clearance groove 21 may also extend from the inner side of the side wall to the outer side of the side wall. The specific implementation can be set according to the inclination angle of the bending pressure head 322 and the actual needs, and is not limited here.

[0064] Please refer to Figure 2 In some embodiments of the invention bending and pressing device 100, the side wall of the fixture seat 20 is provided with a plurality of clearance grooves 21, and the plurality of clearance grooves 21 are arranged at intervals along the length direction of the fixture seat 20.

[0065] The drive assembly 321 is provided with a plurality of bending and pressing heads 322 at the output end facing the fixture seat 20. The plurality of bending and pressing heads 322 are arranged at intervals along the length direction of the fixture seat 20, and each bending and pressing head 322 corresponds to a clearance groove 21.

[0066] In this embodiment, the workpiece includes multiple fastening points. The side wall of the fixture seat 20 is provided with multiple clearance grooves 21. The multiple clearance grooves 21 are arranged at intervals along the length direction of the fixture seat 20 so as to correspond one-to-one with each fastening point on one side of the workpiece. The drive assembly 321 is provided with multiple bending pressure heads 322 facing the output end of the fixture seat 20. The multiple bending pressure heads 322 are arranged at intervals along the length direction of the fixture seat 20, and each bending pressure head 322 is set with a clearance groove 21. With this arrangement, each fastening point of the workpiece can correspond to a clearance groove 21, which in turn corresponds to a bending pressure head 322. The multiple bending pressure heads 322 can simultaneously bend each fastening point of the workpiece, thereby further improving the bending efficiency of the bending device 30 on the workpiece.

[0067] Please refer to Figure 3In some embodiments of the invention's bending and pressing device 100, the clearance groove 21 extends along the movement path of the bending and pressing head 322, and the inclination angle of the bottom wall of the clearance groove 21 is the same as the inclination angle of the inclined surface.

[0068] In this embodiment, the clearance groove 21 extends along the movement path of the bending head 322, and the inclination angle of the bottom wall of the clearance groove 21 is the same as the inclination angle of the inclined surface. Furthermore, the bottom wall of the clearance groove 21 and the bottom wall of the bending head 322 can be set to be located on the same plane. At this time, the clearance groove 21 can play a guiding and supporting role for the bending head 322, thereby improving the operational stability of the bending head 322.

[0069] Please refer to Figure 1 In some embodiments of the invention's bending and pressing device 100, a plurality of bending and pressing devices 30 are provided, and the plurality of bending and pressing devices 30 are arranged at intervals along the circumference of the fixture seat 20.

[0070] In this embodiment, multiple bending and pressing devices 30 are provided, and the multiple bending and pressing devices 30 are arranged at intervals along the circumference of the fixture seat 20; furthermore, the multiple bending and pressing devices 30 are linked to each other to simultaneously bend and press multiple fastening points of the workpiece. This arrangement can improve the efficiency of workpiece bending and pressing.

[0071] Please refer to Figure 1 or Figure 5 In some embodiments of the invention bending device 100, two pairs of the plurality of bending devices 30 are disposed on both sides of the fixture base 20.

[0072] In this embodiment, some of the multiple bending devices 30 are arranged in pairs on both sides of the fixture base 20, that is, multiple pairs of bending devices 30 are provided on both sides of the fixture base 20. Since the bending devices 30 arranged on both sides of the fixture base 20 are opposite to each other and can simultaneously bend the fastening points of the workpiece from both sides, the workpiece can be subjected to uniform force on both sides during bending, reducing the risk of workpiece misalignment and giving the bending device 30 a better bending effect.

[0073] Please refer to Figure 1 In some embodiments of the invention bending device 100, the bottom wall of the fixture seat 20 is provided with adsorption holes 22 for forming negative pressure.

[0074] In this embodiment, the bottom wall of the fixture seat 20 is provided with adsorption holes 22 for forming negative pressure. By forming negative pressure in the adsorption holes 22, the workpiece inside the fixture seat 20 can be fixedly adsorbed within the fixture seat 20, thereby improving the positional stability of the workpiece and reducing the risk of the workpiece shifting relative to the fixture seat 20 during the bending process, thus affecting the bending effect of the workpiece. This improves the practicality of the bending device 30. The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
