Description

Technical Field

[0001] The present invention relates to the technical field of sheet metal processing equipment, and more specifically, to an automatic stamping and forming equipment for automobile body sheet metal parts. Background Art

[0002] With the rapid development of automobile equipment technology, new requirements have been put forward for the quality and processing efficiency of automobiles. At present, stamping is often used in the processing of automobile bodies. The general process for stamping automobile body sheet metal parts is as follows: first, the sheet metal raw material is cut to cut out the shape of the sheet metal part suitable for processing, and then the cut sheet metal part is placed in an extrusion mechanism, and the extrusion mechanism extrudes the sheet metal part to form an automobile body sheet metal part.

[0003] In the related art, the following problems are found: the mold provided on the extrusion mechanism is easily adhered to the sheet metal part, which will result in a low processing yield of the sheet metal part, and at the same time, there are also safety hazards in the processed sheet metal part. Based on this, in some stamping solutions, a layer of stamping oil is applied to the sheet metal part before stamping. The applied stamping oil can reduce the adhesion between the mold on the stamping mechanism and the sheet metal part, so as to improve the yield of the sheet metal part.

[0004] In view of the above related art, the following defects are found: after the sheet metal part is stamped, a coating such as paint needs to be sprayed on the sheet metal part. However, there is stamping oil on the stamped sheet metal part, which will cause the bonding force between the coating and the sheet metal part to decrease. At the same time, when cleaning the stamping oil, the labor and material resources will be correspondingly increased, increasing the processing cost of the sheet metal part. At the same time, the application of stamping oil will reduce the processing efficiency of the sheet metal part. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide an automatic stamping and forming equipment for automobile body sheet metal parts, so as to reduce the stamping cost of the sheet metal part while improving the processing quality of the automobile body sheet metal part and the processing efficiency of the automobile body sheet metal part.

[0006] According to a first aspect of the present invention, there is provided an automatic stamping and forming equipment for automobile body sheet metal parts, the forming equipment comprising a stamping mechanism, a first attaching mechanism, a second attaching mechanism and a flipping mechanism;

[0007] The stamping mechanism includes a stamping frame, an upper stamping die, a lower stamping die and a driving component;

[0008] The lower stamping die is arranged on the stamping frame;

[0009] The upper stamping die is slidably connected to the stamping frame through the driving component, wherein the upper stamping die and the lower stamping die form a stamping space for the sheet metal part;

[0010] The driving component is used to drive the upper stamping die closer to the lower stamping die;

[0011] The first attaching mechanism is arranged on one side of the stamping frame body and is used to attach a film to one side of the sheet metal part;

[0012] The flipping mechanism is arranged between the first attaching mechanism and the stamping mechanism. The flipping mechanism is used to drive the sheet metal part to flip so that the un - attached side of the sheet metal part is exposed;

[0013] The second attaching mechanism is arranged between the flipping mechanism and the stamping mechanism and is used to attach to the un - attached side of the sheet metal part.

[0014] Through the above technical solution, when stamping the body sheet metal part, place the cut sheet metal part raw material on the first attaching mechanism, turn on the first attaching mechanism. The first attaching mechanism attaches a film to one side of the sheet metal part and drives the sheet metal part to move on it. When the sheet metal part moves onto the flipping mechanism, turn on the flipping mechanism. The flipping mechanism clamps the sheet metal part on the first attaching mechanism. After completing the clamping of the sheet metal part, the flipping mechanism flips and transports the sheet metal part to the second attaching mechanism. At this time, the un - attached side of the sheet metal part is exposed. Turn on the second attaching mechanism, and the second attaching mechanism performs the film - attaching work on the un - attached side of the sheet metal part. After both sides of the sheet metal part are film - attached, transport the sheet metal part into the stamping space, adjust the driving component, and the driving component drives the upper stamping die to move. The upper stamping die approaches the lower stamping die to achieve stamping of the sheet metal part. By attaching films to both sides of the sheet metal part, on the one hand, the set film reduces the phenomenon that in the traditional process, stamping oil is applied to the sheet metal part, resulting in an increase in subsequent processes for cleaning the stamping oil; on the other hand, it can reduce the phenomenon that when the stamping mechanism stamps the sheet metal part, the upper stamping die and the lower stamping die directly contact the sheet metal part, causing damage to the sheet metal part, and at the same time prevent the phenomenon of adhesion between the upper stamping die, the lower stamping die and the sheet metal part, so as to improve the stamping quality of the sheet metal part.

[0015] Optionally, the first attaching mechanism includes a first attaching bracket, a first transmission component, a first grasping component, and a first loading platform;

[0016] The first attaching bracket is arranged on one side of the stamping frame body;

[0017] The first transmission component is arranged on the first attaching bracket and is used to transport the sheet metal part on the first attaching bracket;

[0018] The first loading platform is arranged on one side of the first attaching bracket and is used to carry a plurality of films;

[0019] The first gripping component is used to attach the film to one side of the sheet metal part located on the first conveying component.

[0020] Through the above technical solution, the sheet metal part is placed on the first conveying component, and the first conveying component drives the sheet metal part to move on the first attaching bracket. At the same time, the first gripping component is adjusted. The first gripping component transports the film on the first loading platform to the sheet metal part and attaches the film to one side of the sheet metal part.

[0021] Optionally, the flipping mechanism includes a flipping bracket, at least two flipping arms, a power component, and a clamping component;

[0022] The first attaching bracket has a blanking end, and the flipping bracket is arranged on one side of the blanking end;

[0023] The flipping arms are rotatably connected to the flipping bracket through the power component. Among them, at least two of the flipping arms are symmetrically arranged along the length direction of the flipping bracket;

[0024] The clamping component is arranged on the flipping arm, and the clamping component is used to clamp the sheet metal part on the side of the first attaching mechanism;

[0025] The power component is used to simultaneously drive the symmetrically arranged flipping arms to rotate so as to flip the sheet metal part.

[0026] Through the above technical solution, when the film is attached to one side of the sheet metal part by the first attaching mechanism, the sheet metal part continues to move on the first attaching bracket under the action of the first conveying component. When the sheet metal part moves to the blanking end, the flipping arms are adjusted. The flipping arms flip to the blanking end, the clamping component is turned on, and the clamping component clamps the sheet metal part at the blanking end. The flipping arms are further adjusted, and the flipping arms perform a flipping operation on the sheet metal part. The sheet metal part is flipped so that its side without the attached film is exposed, and the sheet metal part is transported to the second attaching mechanism. The second attaching mechanism is turned on, and the second attaching mechanism performs a film attaching operation on the side of the sheet metal part without the attached film. With such a setting, the flipping arms symmetrically arranged along the flipping bracket can flip the sheet metal part. At the same time, the symmetrically arranged flipping arms flip simultaneously to prevent the phenomenon of tearing and damaging the sheet metal part during the flipping process; further, a clamping component is arranged on the flipping arm. On the one hand, it can realize the clamping of the sheet metal part to prevent the sheet metal part from falling when the flipping arm flips the sheet metal part. On the other hand, the arranged clamping component can improve the attaching effect between the sheet metal part and the film, and further improve the stamping quality of the sheet metal part.

[0027] Optionally, the inner wall of the flipping bracket has an arc-shaped groove, the flipping arm extends into the arc-shaped groove and is slidably connected to the side wall of the arc-shaped groove.

[0028] Through the above technical solution, the setting of the arc-shaped groove can limit the movement trajectory of the flipping arm, so that the flipping actions and flipping angles of the symmetrically arranged flipping arms are consistent, thereby effectively reducing the phenomena of tearing and pulling of the sheet metal part during flipping, and further ensuring the stamping quality of the sheet metal part.

[0029] Optionally, the power assembly includes a power motor, a first driving wheel, a second driving wheel, a third driving wheel, a fourth driving wheel, a first driving member, a second driving member, a third driving member, and a connecting rod;

[0030] The first driving wheel is rotatably connected to the flipping bracket, and the first driving wheel is connected to the power motor through the first driving member;

[0031] The power motor is used to drive the first driving wheel to rotate through the first driving member;

[0032] One end of the connecting rod is connected to the first driving wheel, wherein the axial direction of the connecting rod is perpendicular to the length direction of the flipping bracket; <M

[0033] The second driving wheel is rotatably connected to the flipping bracket, the second driving wheel is connected to the first driving wheel through the second driving member, and one side of the flipping arm is connected to the second driving wheel;

[0034] The third driving wheel is connected to the other end of the connecting rod and is rotatably connected to the flipping bracket;

[0035] The fourth driving wheel is connected to the third driving wheel through the third driving member, and the flipping arm on the other side of the flipping bracket is connected to the fourth driving wheel.

[0036] Through the above technical solution, after the clamping component clamps the sheet metal part, the power motor is turned on. The power motor drives the first driving member to move, the first driving member drives the first driving wheel to rotate, the rotation of the first driving wheel makes the second driving member move, the movement of the second driving member drives the second driving wheel to move, the rotation of the second driving wheel drives the flipping arm on one side of the flipping bracket to rotate. At the same time, the rotation of the first driving wheel drives the connecting rod to move. At this time, the connecting rod rotates, the rotation of the connecting rod drives the third driving wheel to rotate, the rotation of the third driving wheel drives the third driving member to move, the movement of the third driving member drives the fourth driving wheel to rotate, and the rotation of the fourth driving wheel makes the flipping arm on the other side of the flipping bracket rotate, achieving the purpose of synchronous movement of the symmetrically arranged flipping arms.

[0037] Optionally, the clamping component includes a first clamping wheel, a second clamping wheel, a first driving member, and a second driving member;

[0038] There are multiple first clamping wheels, and the multiple first clamping wheels are arranged along the length direction of the flipping arm;

[0039] There are multiple second clamping wheels, and the multiple second clamping wheels are arranged along the length direction of the flipping arm,

[0040] wherein, the first clamping wheels and the second clamping wheels form a clamping space for the sheet metal part and the film, and the size of the clamping space is variable;

[0041] The first driving member is used to drive the first clamping wheels to rotate;

[0042] The second driving member is used to drive the second clamping wheels to approach the first clamping wheels.

[0043] Through the above technical solution, when the sheet metal part moves to the blanking end, due to certain inertia, the sheet metal part will move forward for a certain distance. At this time, the flipping arm moves to the blanking end, and the sheet metal part will extend into the clamping space. The first driving member and the second driving member are turned on. The first driving member drives the first clamping wheels to rotate. The rotation of the first clamping wheels enables the sheet metal part to move forward in the clamping space. The second driving member drives the second clamping wheels to approach the first clamping wheels. At this time, the clamping space shrinks, and both the first clamping wheels and the second clamping wheels are in contact with the sheet metal part. In this way, while driving the sheet metal part to move forward, the adhesion between the sheet metal part and the film can be made more firm. When the sheet metal part moves to an appropriate position, the second driving member is further adjusted, the second clamping wheels approach the first clamping wheels further, and the first clamping wheels and the second clamping wheels clamp the sheet metal part to facilitate the subsequent flipping of the sheet metal part.

[0044] Optionally, the first driving member includes a driving motor, a driving belt, and driving wheels;

[0048] Through the above technical solution, when the sheet metal part moves into the clamping space, the driving motor is turned on. The driving motor rotates to drive any one of the driving wheels to rotate. The rotation of any one of the driving wheels drives the driving belt to move. Under the action of the driving belt, multiple driving wheels are driven to rotate. The rotation of the driving wheels drives the corresponding first clamping wheels to rotate. In this way, multiple first clamping wheels can be rotated, and further the sheet metal part can move in the clamping space until it moves to a suitable position.

[0049] Optionally, the second driving member includes a first electromagnet, a second electromagnet, and a return spring;

[0052] The second electromagnet is arranged on the flipping arm through the return spring;

[0053] The return spring is used to drive the second electromagnet to return to its original position.

[0054] Through the above technical solution, when it is necessary to drive the second clamping wheel close to the first clamping wheel, the first electromagnet and the second electromagnet are energized. At this time, the mutually approaching sides of the first electromagnet and the second electromagnet repel each other, the first electromagnet moves away from the second electromagnet, and the movement of the first electromagnet drives the movement of the second clamping wheel, and the second clamping wheel approaches the first clamping wheel, so as to realize the clamping of the sheet metal part. When it is necessary to drive the sheet metal part to move within the clamping space and move the sheet metal part to the second attaching mechanism, the first electromagnet and the second electromagnet are energized. At this time, the mutually approaching sides of the first electromagnet and the second electromagnet attract each other. At this time, the first clamping wheel and the second clamping wheel move away from each other to facilitate the movement of the sheet metal part within the clamping space.

[0055] Optionally, the second attaching mechanism includes a second attaching bracket, a second transmission component, a second grasping component, and a second carrier;

[0059] The second grasping component is used to attach the film to one side of the sheet metal part located on the second transmission component.

[0060] Through the above technical solution, when the flipping mechanism drives the sheet metal part to the second attaching mechanism, the sheet metal part is placed on the second transmission component under the action of the flipping mechanism. The second transmission component drives the sheet metal part to move on the second attaching bracket. At the same time, the second grasping component is adjusted. The second grasping component transports the film on the second carrier platform to the sheet metal part and attaches the film to one side of the sheet metal part, so as to achieve the purpose of attaching films to both sides of the sheet metal part.

[0061] Optionally, the forming device further includes a feeding mechanism; the feeding mechanism includes a feeding turntable, a transporting assembly, and a picking assembly;

The feeding turntable continues to rotate, and the next transporting component transports the sheet metal part with the film attached into the stamping space, and so on in a cycle, which can realize continuous stamping of the sheet metal part, thereby helping to improve the stamping efficiency of the sheet metal part.

[0082] This application provides an automatic stamping and forming device for vehicle body sheet metal parts. Refer to Figure 1, the forming device includes a stamping mechanism 1, a first attaching mechanism 2, a second attaching mechanism 3, a feeding mechanism 5 and a flipping mechanism 4; the first attaching mechanism 2 is arranged on one side of the stamping mechanism 1, and the first attaching mechanism 2 is used for attaching a film to one side of the sheet metal part; the flipping mechanism 4 is arranged on the side of the first attaching mechanism 2 close to the stamping mechanism 1, and the flipping mechanism 4 is used for driving the sheet metal part to flip so that the un-attached side of the sheet metal part is exposed; the second attaching mechanism 3 is arranged on the side of the flipping mechanism 4 away from the first attaching mechanism 2, and the second attaching mechanism 3 is used for attaching a film to the other side of the sheet metal part; the feeding mechanism 5 is arranged on the side of the second attaching mechanism 3 away from the flipping mechanism 4, and the feeding mechanism 5 is used for sending the sheet metal part with the film attached to the position of the stamping mechanism 1 and taking out the stamped sheet metal part from the stamping mechanism 1; the stamping mechanism 1 is used for stamping the combination of the sheet metal part and the film.

[0083] In some embodiments of the present invention, the stamping mechanism 1 includes a stamping frame body 11, an upper stamping die 12, a lower stamping die 13 and a driving component 14; the lower stamping die 13 is installed on the stamping frame body 11; the upper stamping die 12 is slidably connected to the stamping frame body 11 through the driving component 14, wherein a stamping space for the sheet metal part is formed between the upper stamping die 12 and the lower stamping die 13; the driving component 14 is used for driving the upper stamping die 12 to approach the lower stamping die 13. It can be understood that the function of the driving component 14 is to drive the upper stamping die 12 to approach the lower stamping die 13 to achieve the purpose of stamping the sheet metal part. This structure is well known to those skilled in the art and will not be elaborated herein. As an example, the driving component 14 can be set as an oil cylinder. The first attaching mechanism 2 is arranged on one side of the stamping frame body 11 for attaching a film to one side of the sheet metal part; the flipping mechanism 4 is arranged between the first attaching mechanism 2 and the stamping frame body 11; the second attaching mechanism 3 is arranged between the flipping mechanism 4 and the stamping frame body 11 for attaching to the un-attached side of the sheet metal part.

[0084] Specifically, when it is necessary to stamp the sheet metal part, the sheet metal part is placed in the stamping space, the driving component 14 is turned on, and the driving component 14 drives the upper stamping die 12 to approach the lower stamping die 13, and the stamping of the sheet metal part is realized under the cooperation of the upper stamping die 12 and the lower stamping die 13. It should be noted that for sheet metal parts of different specifications, upper stamping dies 12 and lower stamping dies 13 of different specifications can be used, which will not be elaborated herein.

[0085] In some embodiments of the present invention, refer to Figure 1 、 Figure 2 、 Figure 3, the first attaching mechanism 2 includes a first attaching bracket 21, a first transmission component 22, a first grasping component 23, and a first carrier 24; the first attaching bracket 21 is arranged on one side of the stamping frame 11; the first transmission component 22 is arranged on the first attaching bracket 21, and the first transmission component 22 is used for transporting the sheet metal parts on the first attaching bracket 21; the first carrier 24 is arranged on one side of the first attaching bracket 21, the first carrier 24 is used for carrying a plurality of thin films, and the first grasping component 23 is used for attaching the thin film to one side of the sheet metal part located on the first transmission component 22.

[0086] It should be noted that the multiple thin films of the present invention are stacked, that is to say, the stacked multiple thin films are placed on the first carrier 24. When it is necessary to attach the thin film to the sheet metal part on the first transmission component 22, the first grasping component 23 can be turned on. The first grasping component 23 grabs a thin film on the first carrier 24 onto the sheet metal part and attaches the thin film to the sheet metal part.

[0087] As an example, refer to Figure 3 , the first transmission component 22 may include a plurality of first transmission rollers 221, a first transmission motor 222, and a first transmission belt 223; wherein, the plurality of first transmission rollers 221 are rotatably connected to the first attaching bracket 21, the axial direction of the first transmission rollers 221 is the same as the length direction of the first attaching bracket 21, the first transmission belt 223 is wound around the plurality of first transmission rollers 221, and the first transmission motor 222 is used to drive the first transmission rollers 221 to rotate.

[0088] As another example, the first grasping component 23 includes a grasping bracket 231, a rotating bracket 232, a lifting member 233, and a suction member 234; the grasping bracket 231 is arranged on one side of the first attaching bracket 21; the rotating bracket 232 is rotatably connected to the bracket; the suction member 234 is connected to the rotating bracket 232 through the lifting member 233, and the lifting member 233 is used to drive the suction member 234 to move up and down to realize taking the thin film on the first carrier 24 and attaching the thin film to the sheet metal part.

[0089] Specifically, the lifting member 233 may include a lifting screw 2331, a lifting motor 2332, a lifting block 2333, a lifting bracket 2334, and a lifting motor 2332; the lifting bracket 2334 is connected to the rotating bracket 232, the lifting screw 2331 is rotatably connected to the lifting bracket 2334, and the axial direction of the lifting screw 2331 is perpendicular to the moving direction of the sheet metal part on the first attaching bracket 21; the lifting block 2333 is threadedly connected to the lifting screw 2331 and is slidably connected to the lifting bracket 2334, and the lifting motor 2332 is used to drive the lifting screw 2331 to rotate; the suction member 234 is connected to the lifting block 2333.

[0090] As another example, the adsorbing member 234 can be a plurality of suction cups. Further, the adsorbing member 234 can be set into two groups, and the two groups of adsorbing members 234 are arranged oppositely along the length direction of the lifting block 2333. In this way, when one group of adsorbing members 234 grabs the film on the first carrier 24, the other group of adsorbing members 234 can attach the grabbed film to the sheet metal part. After the attachment to one side of the sheet metal part is completed, the rotating bracket 232 rotates, so that the adsorbing member 234 that grabs the film moves to the position of the sheet metal part, and the adsorbing member 234 that has completed the attachment moves to the position of the first carrier 24. In this way, the continuous attachment to the sheet metal part is realized, which helps to improve the attachment efficiency of the film to the sheet metal part.

[0091] It can be understood that in this example, the adsorbing member 234 is connected to the lifting block 2333 through a translation part (not specifically marked in the drawings of this application). Specifically, when the adsorbing member 234 on one side finishes grabbing the film on the first carrier 24, the rotating bracket 232 rotates, so that the adsorbing member 234 with the film moves to near the first attachment bracket 21, and at this time, the plane where the adsorbing member 234 is located is higher than the plane where the first attachment bracket 21 is located. The translation part is turned on, and the translation part drives the adsorbing member 234 to move to directly above the sheet metal part on the first attachment bracket 21. Under the action of the lifting member 233, the adsorbing member 234 approaches the sheet metal part to perform the attachment operation on the sheet metal part. It should be noted that in this example, the function of the translation part is to drive the adsorbing member 234 to perform translational motion. This structure is well-known to those skilled in the art and will not be elaborated in this application.

[0092] Furthermore, referring to Figure 2 、 Figure 3 , the first attachment mechanism 2 further has a pressing assembly 25, and the pressing assembly 25 includes a falling member 251 and a pressing roller 252; the pressing roller 252 is connected to the first attachment bracket 21 through the falling member 251, and the falling member 251 is used to drive the pressing roller 252 to approach the sheet metal part located on the first transportation component.

[0093] It should be noted that in the embodiments of the present invention, the falling member 251 can include a falling bracket, a falling motor, a falling screw, and a falling block (not specifically marked in this application).

Among them, in the embodiment of the present invention, the first driving wheel 432 and the second driving wheel 433 are located on the same side of the flipping bracket 41; the third driving wheel 434 is connected to the other end of the connecting rod 439, and the third driving wheel 434 is rotatably connected to the flipping bracket 41; the fourth driving wheel 435 is connected to the third driving wheel 434 through the third driving member 438, and the flipping arm 42 on the other side of the flipping bracket 41 is connected to the fourth driving wheel 435, wherein the third driving wheel 434 and the fourth driving wheel 435 are located on the same side of the flipping bracket 41.

It should be noted that in the embodiments of the present invention, the number of the first clamping wheels 441 is not specifically limited; there are multiple second clamping wheels 442, and the multiple second clamping wheels 442 are arranged along the length direction of the flipping arm 42.

[0099] It can be understood that when the sheet metal part with a film attached on one side moves on the first attaching bracket 21, when the sheet metal part is about to move to the blanking end, at this time, the flipping arm 42 has been flipped to the position of the blanking end, the clamping space and the movement track of the sheet metal part are on the same horizontal line. Under the action of inertia, part of the sheet metal part moves into the clamping space. At this time, the sheet metal part moving into the clamping space is not enough to complete the flipping operation. The first driving member 443 can be turned on, and the first driving member 443 drives the first clamping wheel 441 to move. In this way, the sheet metal part can move in the clamping space. When the sheet metal part moves to a suitable position (a position convenient for flipping), the second clamping wheel 442 approaches the first clamping wheel 441. At this time, the sheet metal part is clamped, and the subsequent flipping process can be realized.

[0102] It can be understood that there is a slidable connecting block 4444 on the flipping arm 42, and the second clamping wheels 442 are rotatably connected to the connecting block 4444. There are a plurality of first electromagnets 4441, and the plurality of first electromagnets 4441 are connected to the second clamping wheels 442; the second electromagnet 4442 is arranged on the flipping arm 42 through the return spring 4443; the return spring 4443 is used to drive the second electromagnet 4442 to return to its original position.

[0103] Specifically, electricity can be applied to the first electromagnet 4441 and the second electromagnet 4442. When the sides of the first electromagnet 4441 and the second electromagnet 4442 that are close to each other are of opposite genders, the first electromagnet 4441 and the second electromagnet 4442 move away from each other. At this time, the first electromagnet 4441 drives the second clamping wheel 442 away from the first electromagnet 4441, and the second clamping wheel 442 approaches the first clamping wheel 441, so that the clamping of the sheet metal part can be realized.

[0104] In addition, in some embodiments, refer to Figure 5 , a limiting post 412 can also be arranged inside the flipping bracket 41. Correspondingly, a limiting groove 413 corresponding to the limiting post 412 can be arranged on the flipping arm 42.

[0108] Specifically, when the sheet metal part moves to the end of the second attaching bracket 31 on the second attaching mechanism 3, due to a certain inertia, the sheet metal part will move into the transporting space formed by the first clamping arm and the second clamping arm, and the sheet metal part is transported. The feeding turntable 51 rotates, and the feeding turntable 51 drives the transporting component 52 to move to the extrusion mechanism, and the pushing member pushes the sheet metal part into the extrusion space to perform an extrusion operation on the sheet metal part.
