Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flattening device, and particularly relates to a flattening device. BACKGROUND

[0002] The metal sheet on the cover of the server and the like needs to be bent and then flattened due to the strength and disassembly safety. The traditional flattening process is complex and prone to produce metal powder and silk. In the traditional flattening tool, the bending and flattening are generally performed by three devices or two devices. In the three devices, one device is used for bending 90 degrees, another device is used for pressing the bending to 135 degrees, and the third device is used for flattening. In the two devices, one device is used for bending, and the other device is used for flattening. The traditional flattening tool needs more operators and has low production efficiency. SUMMARY

[0003] Therefore, the present application provides a flattening device to solve the problem of low production efficiency caused by the traditional flattening tool needing more operators.

[0004] The present application provides a flattening device, which comprises a first supporting mechanism, a telescopic block, a pushing mechanism, a second supporting mechanism, a pressing mechanism and a power mechanism. The telescopic block is telescopically connected to the first supporting mechanism along a first direction, and a first supporting surface is arranged on the side of the telescopic block away from the first supporting mechanism. The first supporting surface has a supporting position extending out of the first supporting mechanism, a first retracted position partially retracted into the first supporting mechanism, and a second retracted position fully retracted into the first supporting mechanism. The pushing mechanism is slidably connected to the first supporting mechanism along a second direction, and a second supporting surface is arranged on the side of the pushing mechanism away from the first supporting mechanism. When the first supporting surface is in the supporting position, the second supporting surface is in the same plane as the first supporting surface, and the piece to be flattened is adapted to be supported on the first supporting surface and the second supporting surface. The second supporting mechanism is arranged opposite to the first supporting mechanism and is adapted to approach or move away from the first supporting mechanism. The pressing mechanism is installed on the second supporting mechanism and is correspondingly arranged with the telescopic block. The power mechanism cooperates with the pushing mechanism and is adapted to apply a sliding force to the pushing mechanism. The first direction is perpendicular to the second direction.

[0005] Beneficial effects: the first supporting mechanism is used for supporting the telescopic block and the pushing mechanism, the second supporting mechanism is used for supporting the pressing mechanism and moving the pressing mechanism relative to the first supporting mechanism. The telescopic block is arranged in a telescopic manner and can be sequentially bent, pushed down and flattened in cooperation with the pushing mechanism. When the first supporting surface is in the supporting position, the piece to be flattened is supported on the first supporting surface and the second supporting surface, the part supported on the first supporting surface is a bent part which needs to be bent and flattened on another part, and the part supported on the second supporting surface is a body part. The pressing mechanism can be moved under the driving of the second supporting mechanism and can exert a pressing force on the telescopic block and the piece to be flattened. The power mechanism can exert a sliding force on the pushing mechanism to move towards the telescopic block. When the second supporting mechanism approaches the first supporting mechanism, the pressing mechanism presses the telescopic block, the first supporting surface is retracted from the supporting position to the first retracted position, and the telescopic block moves relative to the pushing mechanism in the first direction. Since the telescopic block and the pushing mechanism are arranged close to each other, the pressing mechanism exerts a force on the body part when pressing the telescopic block, and the side part of the pushing mechanism and the pushing mechanism cooperate to exert a force on the bent part, so as to achieve the purpose of bending the piece to be flattened. When the second supporting mechanism continues to move towards the first supporting mechanism, the first supporting surface is retracted from the first retracted position to the second retracted position, and at this time the power mechanism drives the pushing mechanism to move towards the position of the telescopic block in the second direction to push down and flatten the bent part. The present application realizes the three actions of bending, pushing down and flattening in sequence by one flattening device, without the need for excessive manual operation, greatly improving the production efficiency. The flattening device provided by the present application does not need to set multiple pressing mechanisms, but only one pressing mechanism and the pushing mechanism cooperate well, which can realize bending, pushing down and flattening, simplify the structure and layout, and is relatively simple; the telescopic block, the pushing mechanism, the pressing mechanism and the power mechanism are arranged relatively compactly, saving space.

[0006] In an alternative embodiment, the pressing mechanism comprises a moving and rotating assembly, a pressing block and a first reset elastic member; one end of the moving and rotating assembly is rotatably connected with the second supporting mechanism, the other end is correspondingly arranged with the telescopic block and located on the side close to the pushing mechanism; the moving and rotating assembly is adapted to bend the piece to be flattened in cooperation with the pushing mechanism; the pressing block is fixedly connected on the second supporting mechanism and located on the side away from the pushing mechanism and is correspondingly arranged with the telescopic block; the first reset elastic member is connected between the other end of the moving and rotating assembly and the pressing block.

[0007] Beneficial effects: The mobile rotating assembly is located on one side close to the pushing mechanism, and can press the telescopic block and the body part of the to-be-flattened piece to move, and during the process of pressing the telescopic block to move to the first retracted position, the body part close to the bending part of the to-be-flattened piece is fixed and limited to a certain extent, so that the bending part of the to-be-flattened piece can be bent according to the preset position and angle, and displacement or misplacement of the to-be-flattened piece is prevented to cause poor bending quality; since one end of the mobile rotating assembly is rotatably connected with the second supporting mechanism, when the pushing mechanism moves in the direction of the telescopic block, the mobile rotating assembly can be rotatably stressed, so that smooth movement of the pushing mechanism is ensured, and the bending part can be limited and guided to prevent the bending part from being curled or deformed. The pressing block is located on the side away from the pushing mechanism, can press the telescopic block and the body part of the to-be-flattened piece to move, and can also fix and limit the body part to prevent the body part from being deformed under stress. The first reset elastic member can drive the mobile rotating assembly to rotate to automatically reset when the pushing mechanism moves away from the telescopic block through the elastic force, so that the flattening process of the next to-be-flattened piece is facilitated.

[0008] In an alternative embodiment, the mobile rotating assembly comprises a connecting seat, a rotating arm, two bearing fixing plates and a mobile bending block. The connecting seat is fixedly connected to the second supporting mechanism. The side of the connecting seat away from the second supporting mechanism is provided with a rotating groove which is an arc-shaped recess. The rotating arm is provided with an arc-shaped protrusion on one side, which is rotatably arranged in the arc-shaped recess. The other side is provided with a limiting sliding groove. The limiting sliding groove is inclinedly arranged. The groove bottom of the limiting sliding groove is a sliding surface. The distance between the sliding surface and the connecting seat gradually increases in the direction away from the pressing block. The two ends of the rotating arm are respectively provided with rotating shafts. The two bearing fixing plates are fixedly connected to the two ends of the connecting seat. The bearing fixing plates are provided with shaft holes. The rotating shafts are rotatably connected to the shaft holes. One end of the mobile bending block is provided with a limiting sliding block which is slidably connected to the limiting sliding groove. The other end is a pressing end suitable for pressing the to-be-flattened piece. The side of the mobile bending block facing the pushing mechanism is provided with an avoiding interval between the pushing mechanism. The avoiding interval is equal to the thickness of the to-be-flattened piece. The side of the mobile bending block facing the pushing mechanism is provided with an abutting strip which is suitable for abutting with the side surface of the pushing mechanism. The first reset elastic member is connected between the mobile bending block and the pressing block. The distance between the abutting strip and the end surface of the pressing end is a first distance. The to-be-flattened piece after being bent includes a body part and a bending part. The distance between the end of the bending part away from the body part and the body part is a second distance. The first distance is greater than the second distance.

[0009] Beneficial effects: The connecting seat can realize fixed connection with the second supporting mechanism, the rotating cooperation of the arc-shaped groove on the connecting seat and the arc-shaped protrusion on the rotating arm can realize the rotating cooperation of the rotating arm relative to the second supporting mechanism, and interference and friction can be avoided; the rotating connection of the two bearing fixing plates and the rotating shafts at the two ends of the rotating arm can rotatably connect the rotating arm on the connecting seat. The setting of the avoidance interval can obtain better bending effect. The rotating arm is provided with a limiting sliding groove, the moving bending block is provided with a limiting sliding block, the sliding cooperation of the limiting sliding block and the limiting sliding groove realizes the sliding connection between the moving bending block and the rotating arm; when the first supporting surface moves from the supporting position to the first retracted position, the moving bending block applies a pressing force in the first direction to the telescopic block and is subjected to a reverse force applied by the telescopic block in the first direction, and since there is no second direction component force and the distance between the sliding surface and the connecting seat gradually increases in the direction away from the pressing block, the sliding surface generates resistance in the second direction, so that the moving bending block does not move in the second direction during bending, the avoidance interval can be maintained, and better bending effect can be realized through the avoidance interval; when the first supporting surface moves from the first retracted position to the second retracted position, at the beginning of the movement of the pushing mechanism in the direction of the telescopic block under stress, the moving bending block first moves in the second direction under stress, so that the pushing mechanism can gradually push down the bent part, and after a certain angle is pushed down, the moving bending block rotates together with the rotating arm under stress, so that the pushing mechanism can facilitate flattening the bent part. The abutting strip can be used to space a certain distance between the pushing mechanisms, so that the pushing mechanisms apply force to the moving bending block through the abutting strip, avoiding extrusion and friction on the bent part. The first distance is greater than the second distance, which can ensure that there is no contact between the bent part and the abutting strip, avoiding bending deformation of the bent part.

[0011] Beneficial effects: The limiting sliding groove is a through groove, which can facilitate the connection between the moving bending block and the rotating arm.

[0015] In an alternative embodiment, a second reset elastic member is further included, the first supporting mechanism is provided with an expansion slot, and the second reset elastic member is connected between the bottom of the expansion slot and the expansion block.

[0016] Beneficial effects: The arrangement of the second reset elastic member can drive the expansion block to return to the supporting position through its own elastic force when the second supporting mechanism moves away from the first supporting mechanism and the pressing mechanism no longer exerts the pressing force. The arrangement of the expansion slot can limit the movement of the expansion block and hide the second reset elastic member.

[0017] In an alternative embodiment, the pressing mechanism further includes a pressing plate connected with the second supporting mechanism through an elastic mechanism; the moving rotating assembly and the pressing block are both connected to the pressing plate and located on the side of the pressing plate away from the second supporting mechanism; and the elastic mechanism is a nitrogen spring.

[0018] Beneficial effects: The pressing plate can be used to connect the moving rotating assembly and the pressing block to realize the synchronous control of the two. The initial pressure of the nitrogen spring is relatively large, and the nitrogen spring is compressed only when the second supporting mechanism continues to move towards the first supporting mechanism after the pressing mechanism presses the expansion block until the first supporting surface is in the second retracted position, thereby realizing constant pressure and delay action.

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0050] The embodiments of the present application will be described below in conjunction with Figures 1 to 18 .

[0051] According to the embodiment of the present application, a flattening device is provided, comprising a first supporting mechanism 1, a telescopic block 2, a pushing mechanism 3, a second supporting mechanism 4, a pressing mechanism 5 and a power mechanism 6. The telescopic block 2 is telescopically connected to the first supporting mechanism 1 along a first direction, and a first supporting surface is arranged on the side of the telescopic block 2 away from the first supporting mechanism 1. The first supporting surface has a supporting position extending out of the first supporting mechanism 1, a first retracted position partially retracted into the first supporting mechanism 1, and a second retracted position fully retracted into the first supporting mechanism 1. The pushing mechanism 3 is slidably connected to the first supporting mechanism 1 along a second direction, and a second supporting surface is arranged on the side of the pushing mechanism 3 away from the first supporting mechanism 1. When the first supporting surface is in the supporting position, the second supporting surface is in the same plane as the first supporting surface, and a flattening object 100 is adapted to be supported on the first supporting surface and the second supporting surface. The second supporting mechanism 4 is arranged opposite to the first supporting mechanism 1, and is adapted to move close to or away from the first supporting mechanism 1. The pressing mechanism 5 is installed on the second supporting mechanism 4 and is arranged corresponding to the telescopic block 2. The power mechanism 6 cooperates with the pushing mechanism 3 and is adapted to apply a sliding force to the pushing mechanism 3. The first direction is perpendicular to the second direction, and when the second supporting mechanism 4 moves close to the first supporting mechanism 1, the pressing mechanism 5 presses the telescopic block 2, the first supporting surface is retracted to the first retracted position, the pushing mechanism 3 cooperates with the pressing mechanism 5 to bend the flattening object 100, and when the second supporting mechanism 4 continues to move towards the first supporting mechanism, the first supporting surface is retracted to the second retracted position, the power mechanism 6 drives the pushing mechanism 3 to move towards the telescopic block 2 and flatten the bent flattening object 100. Specifically, the first direction is perpendicular to the first supporting surface, and the second direction is perpendicular to the first direction and parallel to the first supporting surface. The flattening object 100 can be an upper cover of a server case, and the flattening structure can be arranged on both sides of the upper cover.

[0052] The first supporting mechanism 1 is used for supporting the telescopic block 2 and the pushing mechanism 3, the second supporting mechanism 4 is used for supporting the pressing mechanism 5 and driving the pressing mechanism 5 to move relative to the first supporting mechanism 1. The telescopic block 2 is arranged in a telescopic mode and can be sequentially bent, pushed down and flattened in cooperation with the pushing mechanism 3. When the first supporting surface is in the supporting position, the piece to be flattened 100 is supported on the first supporting surface and the second supporting surface, the part supported on the first supporting surface is the bent part 101 which needs to be bent and flattened on another part subsequently, and the part supported on the second supporting surface is the body part 102. The pressing mechanism 5 can be driven by the second supporting mechanism 4 to move and apply a pressing force to the telescopic block 2 and the piece to be flattened 100. The power mechanism 6 can apply a sliding force to the pushing mechanism 3 to move towards the telescopic block 2. When the second supporting mechanism 4 moves towards the first supporting mechanism 1, the pressing mechanism 5 presses the telescopic block 2, the first supporting surface is retracted from the supporting position to the first retracted position, the telescopic block 2 moves relative to the pushing mechanism 3 in the first direction, since the telescopic block 2 and the pushing mechanism 3 are arranged close to each other, the pressing mechanism 5 applies a force to the body part 102 when pressing the telescopic block 2, and applies a force to the bent part 101 together with the side of the pushing mechanism 3 to achieve the purpose of bending the piece to be flattened 100. When the second supporting mechanism 4 continues to move towards the first supporting mechanism, the first supporting surface is retracted from the first retracted position to the second retracted position, at this time, the power mechanism 6 drives the pushing mechanism 3 to move towards the position of the telescopic block 2 in the second direction to push down and flatten the bent part 101. The present application realizes the three actions of bending, pushing down and flattening in sequence by one flattening device, without the need for excessive manual operation, greatly improving the production efficiency. The flattening device provided by the present application only needs one set of pressing mechanism 5 and pushing mechanism 3 to cooperate well, which can realize bending, pushing down and flattening, simplifying the structure and layout. The telescopic block 2, the pushing mechanism 3, the pressing mechanism 5 and the power mechanism 6 are arranged compactly, saving space.

[0053] In one embodiment, the pressing mechanism 5 comprises a moving and rotating assembly 51, a pressing block 52 and a first reset elastic member 53. One end of the moving and rotating assembly 51 is rotatably connected to the second supporting mechanism 4, and the other end is arranged corresponding to the telescopic block 2 and located close to the pushing mechanism 3. The moving and rotating assembly 51 is adapted to bend the piece to be flattened 100 in cooperation with the pushing mechanism 3. The pressing block 52 is fixedly connected to the second supporting mechanism 4 and arranged corresponding to the telescopic block 2 and spaced apart from the moving and rotating assembly 51 and located away from the pushing mechanism 3. The first reset elastic member 53 is connected between the other end of the moving and rotating assembly 51 and the pressing block 52.

[0054] The mobile rotating assembly 51 is located on the side close to the pushing mechanism 3, and can press the telescopic block 2 and the body part 102 of the to-be-flattened piece 100 to move, and during the movement of the telescopic block 2 to the first retracted position, the body part 102 close to the bent part 101 of the to-be-flattened piece 100 is fixed and limited, so that the bent part 101 of the to-be-flattened piece 100 can be bent according to the preset position and angle, and the displacement or misplacement of the to-be-flattened piece 100 is prevented, so that the bending quality is poor. Since one end of the mobile rotating assembly 51 is rotatably connected with the second supporting mechanism 4, when the pushing mechanism 3 moves in the direction of the telescopic block 2, the mobile rotating assembly 51 can be rotated under force, so that the smooth movement of the pushing mechanism 3 is ensured, and the bent part 101 can be limited and guided, so that the bent part 101 is prevented from being curled or deformed. The pressing block 52 is located on the side away from the pushing mechanism 3, and can press the telescopic block 2 and the body part 102 of the to-be-flattened piece 100 to move, and can also limit and fix the body part 102, so that the body part 102 is prevented from being deformed under force. The first reset elastic member 53 can drive the mobile rotating assembly 51 to rotate to automatically reset when the pushing mechanism 3 moves away from the telescopic block 2, so that the flattening process of the next to-be-flattened piece 100 is facilitated. Specifically, the first reset elastic member 53 can be a spring, and the pressing block 52 and the mobile rotating assembly 51 are respectively provided with spring grooves, and the two ends of the first reset elastic member 53 are respectively arranged in the two spring grooves.

[0055] In one embodiment, the mobile rotating assembly 51 comprises a connecting seat 511, a rotating arm 512, two bearing fixing plates 513 and a mobile bending block 514, the connecting seat 511 is fixedly connected to the second supporting mechanism 4, one side of the connecting seat 511 away from the second supporting mechanism 4 is provided with a rotating groove, the rotating groove is an arc-shaped recess; one side of the rotating arm 512 is provided with an arc-shaped protrusion, the arc-shaped protrusion is rotatably arranged in the arc-shaped recess, the other side is provided with a limiting sliding groove; the limiting sliding groove is obliquely arranged, the groove bottom of the limiting sliding groove is a sliding surface, the distance between the sliding surface and the connecting seat 511 gradually increases in the direction away from the pressing block 52; both ends of the rotating arm 512 are respectively provided with rotating shafts 5121 protruding; the two bearing fixing plates 513 are fixedly connected to both ends of the connecting seat 511, the bearing fixing plates 513 are provided with shaft holes, the rotating shafts 5121 are rotatably connected to the shaft holes; one end of the mobile bending block 514 is provided with a limiting sliding block protruding, the limiting sliding block is slidably connected to the limiting sliding groove; the other end is a pressing end suitable for pressing the to-be-shot flat piece 100; the side of the mobile bending block 514 facing the pushing mechanism 3 is provided with an avoiding interval from the pushing mechanism 3, the avoiding interval is equal to the thickness of the to-be-shot flat piece 100; the side of the mobile bending block 514 facing the pushing mechanism 3 is provided with an abutting strip 5141 protruding, the abutting strip 5141 is suitable for abutting with the side of the pushing mechanism 3; the first reset elastic member 53 is connected between the mobile bending block 514 and the pressing block 52; the distance between the abutting strip 5141 and the end face of the pressing end is a first distance, the to-be-shot flat piece 100 after being bent comprises a body part 102 and a bent part 101, the distance between one end of the bent part 101 away from the body part 102 and the body part 102 is a second distance, the first distance is greater than the second distance.

[0056] The connecting seat 511 can be fixedly connected with the second supporting mechanism 4. The rotating cooperation of the arc-shaped recess on the connecting seat 511 and the arc-shaped protrusion on the rotating arm 512 can realize the rotating cooperation of the rotating arm 512 relative to the second supporting mechanism 4, so as to avoid interference and friction. The rotating connection of the two bearing fixing plates 513 and the rotating shaft 5121 at both ends of the rotating arm 512 can rotatably connect the rotating arm 512 on the connecting seat 511. The setting of the avoiding interval can obtain a better bending effect. The rotating arm 512 is provided with a limiting sliding groove, the moving bending block 514 is provided with a limiting sliding block, the sliding cooperation of the limiting sliding block and the limiting sliding groove realizes the sliding connection between the moving bending block 514 and the rotating arm 512. When the first supporting surface moves from the supporting position to the first retracted position, the moving bending block 514 applies a pressing force in the first direction to the telescopic block 2 and is subjected to a reverse force applied by the telescopic block 2 in the first direction. Since there is no second direction component force, and the distance between the sliding surface and the connecting seat 511 gradually increases in the direction away from the pressing block 52, the sliding surface generates resistance in the second direction, so that the moving bending block 514 will not move in the second direction during the bending process, and the avoiding interval can be maintained, and a better bending effect can be realized through the avoiding interval. When the first supporting surface moves from the first retracted position to the second retracted position, at the beginning of the movement of the pushing mechanism 3 in the direction of the telescopic block 2 under stress, the moving bending block 514 first moves in the second direction under stress, so that the pushing mechanism 3 can gradually push down the bent part 101, and after pushing down by a certain angle, the moving bending block 514 drives the rotating arm 512 to rotate together under stress, so that the pushing mechanism 3 can facilitate the flattening of the bent part 101. The abutting strip 5141 can be used to space a certain distance between the pushing mechanisms 3, so that the pushing mechanisms 3 apply a force to the moving bending block 514 through the abutting strip 5141, avoiding extrusion and friction on the bent part 101. The first distance is greater than the second distance, which can ensure that there is no contact between the bent part 101 and the abutting strip 5141, avoiding the bending deformation of the bent part 101.

[0057] In one embodiment, the moving rotating assembly 51 further comprises a first limiting plate 515 and a second limiting plate 516.

The second limiting plate 516 is connected to the rotating arm 512 and located on the other side facing the pressing block 52.

Moreover, the initial pressure of the nitrogen spring is large, and when the pressing mechanism 5 presses the expansion block 2 until the first supporting surface is in the second retracted position, the second supporting mechanism 4 continues to move towards the first supporting mechanism 1, and the nitrogen spring is compressed, so as to realize constant pressure and delay action.

[0068] The pushing-down inclined surface 311 can apply an inclined force to the bent part 101, and the force can be divided into components in the first direction and the second direction, so that the bent part 101 is more easily pushed down and bent to a larger angle. The flattening surface 312 can apply a downward pressing force from the side of the bent part 101 away from the body part 102, and then flatten the bent part 101, so that the bent part 101 is bent to be parallel to the body part 102.

The driving slope is in sliding fit with the matching slope 313, so as to convert the pressing force in the first direction into the pushing force in the second direction. The second pressing block 62 can push the block 31 after the flat folding, so as to prevent the block 31 from being upturned and causing poor flat folding effect.

[0075] The third reset elastic member 34 can pull the pushing mechanism 3 back to the original position in the direction away from the telescopic block 2 by the elastic force of the third reset elastic member 34 when the power mechanism 6 no longer applies the force to the pushing mechanism 3.
