Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and specifically relates to a side flanging adjustment stamping die. Background Art

[0002] In the cold stamping process, side flanging is an important forming process. Side flanging is a forming process in the cold stamping process. It refers to a processing method of bending the material along a certain curve or straight line on the side of the blank to a certain angle or shape. Generally speaking, it is to fold up the side part of the flat blank through the action of a stamping die to form a structure with a specific shape and function.

[0003] When performing side flanging stamping operations on metal profiles, traditional dies are difficult to effectively fix the metal profiles during the stamping process. The metal profiles are prone to move left and right during stamping, resulting in inaccurate flanging positions, greatly affecting the product quality and reducing the qualified rate of the products. Existing dies usually can only achieve simple stamping actions. The clamping, stamping, flanging operations, etc. of metal profiles all need to be carried out by corresponding equipment separately, and it is impossible to perform efficient flanging operations on the front and rear ends of the metal profiles simultaneously. Often, multiple operations or complex process conversions are required to complete the flanging, which not only consumes a lot of time but also seriously affects the production efficiency and is difficult to meet the needs of large-scale production. Therefore, we introduce a side flanging adjustment stamping die. Summary of the Invention

Detailed implementation manners

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] Embodiment

[0053] Please refer to Figure 1 - 18 , the present invention provides a technical solution:

[0054] A side-turning edge adjustment stamping die includes a stamping table 1. Legs 3 are provided at the bottom of the stamping table 1, and a reinforcing frame 2 is connected between the legs 3. The stamping table 1 is the support platform of the entire die. The legs 3 provided at the bottom of the stamping table 1 play a supporting role, while the reinforcing frame 2 connected between the legs 3 can enhance the overall stability and structural strength of the stamping table 1, prevent deformation due to uneven stress during stamping, and ensure the smoothness of the die during operation.

[0055] A cross-frame 4 and a lower die base 7 located between the cross-frames 4 are provided at the upper end of the stamping table 1. An upper die base 9 driven by a hydraulic cylinder 11 is provided below the cross-frame 4; the hydraulic cylinder 11 is fixed in the middle of the upper end of the cross-frame 4, and the piston rod 111 at the output end of the bottom of the hydraulic cylinder 11 passes through the cross-frame 4 and is fixedly connected to the middle of the upper end of the upper die base 9.

[0056] An upper stamping seat 10 is provided inside the upper die base 9. A receiving groove 93 for receiving the upper part of the upper stamping seat 10 is provided at the lower end of the upper die base 9. Limiting grooves 94 are provided in the middle of the four side walls of the receiving groove 93. Limiting blocks 101 are provided at the tops of the four side walls of the upper stamping seat 10, and the limiting blocks 101 are slidably connected in the corresponding limiting grooves 94. This limiting structure enables the upper stamping seat 10 to slide only along the direction of the limiting grooves 94 inside the upper die base 9, ensuring the stability and accuracy of the movement of the upper stamping seat 10.

[0057] The upper end of the upper stamping seat 10 is also connected to the top wall of the receiving groove 93 through a buffer spring 104. The buffer spring 104 can buffer the impact force received by the upper stamping seat 10 during stamping, reduce the wear of the die, extend the service life of the die, and can improve the quality of the stamped parts, avoiding deformation or damage of the stamped parts due to excessive impact force.

[0058] And side stamping parts 6 are connected to the front and rear ends of both the upper die base 9 and the upper stamping seat 10;

[0059] The side stamping parts 6 include two groups of left and right rotating arms 61 and a stamping head 64 connected between the bottoms of the two groups of left and right rotating arms 61;

[0060] Two groups of left and right first slots 91 are respectively provided at the bottom of the front and rear ends of the upper die base 9. The first pin shafts 63 provided on the upper parts of the rotating arms 61 are connected to the connection holes 92 in the corresponding first slots 91. Two groups of left and right second slots 102 are respectively provided at the tops of the front and rear ends of the upper stamping seat 10. First inclined slots 103 are provided on the side walls of the second slots 102, and both ends of the second pin shafts 62 connected to the tops of the rotating arms 61 are inserted into the corresponding first inclined slots 103.

[0061] This connection structure enables, during the stamping process, when the upper stamping seat 10 moves upward relative to the upper die base 9, through the sliding of the second pin shaft 62 within the first inclined slot 103, to drive the rotating arm 61 to rotate around the first pin shaft 63, thereby realizing the swinging of the stamping head 64, facilitating the flanging operation on the front and rear ends of the metal profile 15.

[0062] When the hydraulic cylinder 11 is activated, the piston rod 111 extends downward, pushing the upper die base 9 to move downward. The upper stamping seat 10 inside the upper die base 9 moves downward together with the upper die base 9. During this process, the upper stamping seat 10 gradually approaches the metal profile 15 placed on the lower stamping seat plate 121. Due to the limitation between the upper stamping seat 10 and the upper die base 9 through the limit block 101 and the limit slot 94, as well as the connection of the buffer spring 104, the upper stamping seat 10 can maintain a stable movement trajectory and accurately contact the upper surface of the metal profile 15.

[0063] Generation of the pre - pressing force:

[0064] After the upper stamping seat 10 contacts the upper surface of the metal profile 15, as the upper die base 9 continues to move downward, the upper stamping seat 10 begins to be resisted by the metal profile 15. At this time, the buffer spring 104 plays an important role. It is gradually compressed and undergoes elastic deformation. According to Hooke's law, the elastic force of the spring is proportional to the deformation amount. The elastic force of the buffer spring 104 increases with the increase of the compression amount, thereby enabling the upper stamping seat 10 to exert a gradually increasing pre - pressing force on the metal profile 15. The magnitude of this pre - pressing force can be controlled by adjusting the stiffness and the initial compression amount of the buffer spring 104 to meet the pre - pressing requirements of metal profiles 15 with different materials and thicknesses.

[0065] Stable maintenance of the pre - pressing fixation:

[0066] During the stamping process, the upper stamping seat 10 continuously exerts a pre - pressing force on the metal profile 15 to ensure that the metal profile 15 does not move forward or backward during the flanging operation. At the same time, the frictional force between the upper stamping seat 10 and the metal profile 15 further enhances the fixation effect. Since the lower end surface of the upper stamping seat 10 is in close contact with the upper surface of the metal profile 15, the frictional force is proportional to the pre - pressing force. Therefore, a larger pre - pressing force can generate a larger frictional force, effectively preventing the metal profile 15 from sliding in the horizontal direction.

[0067] Synergistic effect of the pre - pressing fixation and the subsequent flanging operation:

[0068] Synergy with the side stamping part 6:

[0069] After the upper stamping seat 10 pre-compresses and fixes the metal profile 15, the upper die base 9 continues to move downward, and the upper stamping seat 10 moves upward relative to the upper die base 9. Through the sliding of the second pin shaft 62 in the first inclined groove 103, the rotating arm 61 is driven to rotate around the first pin shaft 63, causing the stamping head 64 to swing downward. Since the metal profile 15 has been pre-compressed and fixed by the upper stamping seat 10, the stamping head 64 can accurately stamp downward on the top of the front and rear ends of the metal profile 15, causing the contact area between the lower end of the metal profile 15 and the arc-shaped contact surface 122 to bend and deform, realizing precise flanging operation. Without the pre-compression and fixation of the upper stamping seat 10, the metal profile 15 may be displaced under the action of the stamping head 64, resulting in inaccurate flanging positions and affecting product quality.

[0070] Cooperation with the lower stamping seat assembly 12:

[0071] The rotation of the turntable 143 drives the rotation of the annular seat 145. The inclined surface 146 on the annular seat 145 pushes the second roller 124 in the lower stamping seat assembly 12 to roll upward, causing the lower stamping seat plate 121 to move upward. The pre-compression and fixation function of the upper stamping seat 10 ensures the stability of the metal profile 15 during the coordinated movement with the lower stamping seat plate 121. When the lower stamping seat plate 121 moves upward, the metal profile 15 can move upward together with the lower stamping seat plate 121 and cooperate with the stamping head 64 in the side stamping part 6 to realize the flanging operation of the front and rear ends of the metal profile 15. If the metal profile 15 is not pre-compressed and fixed, when the lower stamping seat plate 121 moves upward, the metal profile 15 may slide relative to the lower stamping seat plate 121, resulting in problems such as wrinkles and cracks during the flanging process.

[0072] Importance of pre-compression and fixation:

[0073] In the side flanging stamping operation, the pre-compression and fixation of the metal profile 15 by the upper stamping seat 10 is a key link in the entire stamping process. It can ensure that the metal profile 15 maintains a stable position during the subsequent flanging process, avoiding displacement, shaking or deformation due to external forces during the stamping process, thereby ensuring the accuracy and quality of the flanging operation. If the position of the metal profile 15 is unstable during the stamping process, it may lead to problems such as inconsistent flanging dimensions, deviation of flanging angles, and uneven surfaces, seriously affecting the qualification rate and service performance of the product.

[0074] On the left and right sides of the upper die base 9, auxiliary support components 5 are connected to the vertical parts of the cross frame 4;

[0075] The auxiliary support component 5 includes a cross plate 51 integrally formed and connected to the left and right sides of the top of the upper die base 9, a T-shaped slider 52 connected to the end of the cross plate 51, a socket frame 53 connected to the outside of the T-shaped slider 52, and an auxiliary support wheel 55 movably connected to the socket frame 53 by a U-shaped seat 54;

[0076] The lower end of the horizontal plate 51 is connected and fixed to the bottom side of the upper die base 9 by a diagonal bracing plate 56;

[0077] On the inner wall of the vertical part of the horizontal frame 4, there is a T-shaped chute 41 for slidingly connecting a T-shaped slider 52. A socket frame 53 is sleeved outside the vertical part of the horizontal frame 4, and the auxiliary support wheel 55 is closely attached to the side wall of the vertical part of the horizontal frame 4.

[0078] The lower end of the horizontal plate 51 is connected and fixed to the bottom side of the upper die base 9 by a diagonal bracing plate 56, enhancing the stability of the connection between the horizontal plate 51 and the upper die base 9. On the inner wall of the vertical part of the horizontal frame 4, there is a T-shaped chute 41 for slidingly connecting a T-shaped slider 52. A socket frame 53 is sleeved outside the vertical part of the horizontal frame 4, and the auxiliary support wheel 55 is closely attached to the side wall of the vertical part of the horizontal frame 4. The sliding of the T-shaped slider 52 in the T-shaped chute 41 provides precise guidance for the up and down movement of the upper die base 9, ensuring the straightness of the movement of the upper die base 9. The auxiliary support wheel 55 further enhances the stability of the upper die base 9 during movement, reducing shaking and deviation, and improving the stamping accuracy.

[0079] On both the left and right sides of the lower die base 7, there are side clamping and adjusting parts 13 and lower abutting components 8 distributed up and down. The top of the lower abutting component 8 contacts the lower end of the auxiliary support component 5 (this contact relationship enables the movement of the auxiliary support component 5 to be transmitted to the lower abutting component 8 during stamping, thereby driving the subsequent transmission component 14 to act). Above the lower die base 7, there is a lower stamping seat component 12;

[0080] The lower abutting component 8 includes a T-shaped seat 81, a abutting wheel 87 movably connected to the upper end of the T-shaped seat 81 by a vertical plate 86, and a rack 83 connected to the inside of the T-shaped seat 81;

[0081] The top of the abutting wheel 87 is located in the inclined chute 561 at the lower end of the diagonal bracing plate 56;

[0082] The rack 83 extends into the interior of the lower die base 7 through a lower reserved groove 71 at the bottom of the lower die base 7.

[0083] A row of first rollers 82 are provided in front of and behind the T-shaped seat 81. The bottoms of the first rollers 82 rest on the upper surface of the stamping table 1, reducing the friction when the T-shaped seat 81 moves and making the movement smoother.

[0084] The inner side of the vertical plate 86 is connected to the upper end of the T-shaped seat 81 by an inclined support plate 88, enhancing the stability of the vertical plate 86.

[0085] The outer end of the T-shaped seat 81 is provided with a polished rod 84, on which a return spring 85 is sleeved. The polished rod 84 is inserted into a reserved through hole at the bottom of the cross frame 4, and the outer end of the return spring 85 is connected to a spring receiving slot 42 on the inner side of the bottom of the cross frame 4. The return spring 85 can make the T-shaped seat 81 return to the initial position after stamping is completed, preparing for the next stamping.

[0086] When the auxiliary support assembly 5 moves downward along with the upper die holder 9, the movement of the inclined support plate 56 drives the abutting wheel 87 to move through the inclined chute 561, thereby driving the T-shaped seat 81 to move. The rack 83 extends into the interior of the lower die holder 7 through a lower reserved slot 71 at the bottom of the lower die holder 7 and is used for meshing transmission with the transmission assembly 14.

[0087] A transmission assembly 14 is centrally arranged inside the lower die holder 7. The left and right two sets of side clamping and adjusting parts 13 are movably connected to the top of the transmission assembly 14, and the left and right two sets of lower abutting components 8 are meshingly connected to the lower part of the transmission assembly 14. The bottom of the lower stamping seat assembly 12 is supported on the top of the transmission assembly 14;

[0088] The transmission assembly 14 includes a vertical rotating shaft 141, a turntable 143 connected to the top of the vertical rotating shaft 141, an annular seat 145 arranged at the upper end of the turntable 143, and a gear 142 fixed to the lower part of the vertical rotating shaft 141;

[0089] The lower end of the vertical rotating shaft 141 is inserted into a rotating shaft reserved hole at the upper end of the stamping table 1, so that the gear 142 is located on the upper surface of the stamping table 1, and the gear 142 is meshed between the front and rear two sets of racks 83. This meshing structure enables the gear 142 to rotate when the rack 83 moves along with the T-shaped seat 81, and then drives the vertical rotating shaft 141 and the turntable 143 to rotate.

[0090] The side clamping and adjusting part 13 includes a clamping arm 131, a clamping plate 133 fixed to the top of the outer end of the clamping arm 131, and rubber clamping blocks 134 fixed at equal intervals on the inner wall of the clamping plate 133. The inner end of the clamping arm 131 extends into the interior of the lower die holder 7 through an upper reserved slot 72 on the side of the lower die holder 7, and a vertical pin 132 on the inner end of the clamping arm 131 is connected to a corresponding second inclined slot 144 on the turntable 143.

[0091] When the turntable 143 rotates, through the cooperation of the second inclined slot 144 and the vertical pin 132, the clamping arm 131 can be made to move linearly, thereby realizing the clamping and loosening actions of the clamping plate 133 on both sides of the metal profile 15. The rubber clamping blocks 134 can increase the friction between the clamping plate 133 and the metal profile 15, and at the same time avoid damaging the surface of the metal profile 15. When the rubber clamping blocks 134 come into contact with the metal profile 15 and deform, when the clamping plate 133 clamps both sides of the metal profile 15, the stamping head 64, the upper stamping seat 10, and the lower stamping seat plate 121 can gradually reach as Figure 18The state of flanging the front and rear ends of the metal profile 15 as shown;

[0092] During the stamping process, the position stability of the metal profile 15 directly affects the precision of flanging. By clamping both sides of the metal profile 15 with rubber clamping blocks 134, it can ensure that the metal profile 15 remains in a fixed position during the process of the stamping head 64 rotating downward and the lower stamping seat plate 121 moving upward, enabling the position, angle, and size of the flanging to be accurately carried out according to the design requirements, improving the precision and consistency of the flanging operation.

[0093] Reducing stamping defects: If the metal profile 15 moves during the stamping process, it may cause stamping defects such as uneven flanging, wrinkles, and cracks. Through the effective clamping effect, the movement of the metal profile 15 is prevented, the generation of these stamping defects is reduced, and the qualified rate and quality of the product are improved. At the same time, the stable stamping process also helps to protect the die, reducing the abnormal wear and damage of the die caused by the movement of the metal profile, and extending the service life of the die.

[0094] The lower stamping seat assembly 12 includes a lower stamping seat plate 121, rectangular limit posts 123 provided at the four corners at the lower end of the lower stamping seat plate 121, and second rollers 124 movably connected by two sets of front and rear connecting seats 125 at the lower end of the lower stamping seat plate 121;

[0095] The rectangular limit posts 123 are inserted into the corresponding corners inside the lower die base 7 to limit the position of the lower stamping seat plate 121, ensuring its stability and accuracy during the up and down movement.

[0096] Arc-shaped contact surfaces 122 are provided at the front and rear ends of the lower stamping seat plate 121 to facilitate better fitting with the metal profile 15.

[0097] The arc-shaped contact surfaces 122 can provide a smooth guiding path for the flow of the metal material. When the metal material is under pressure, it will flow and extend along the shape of the arc-shaped contact surfaces 122, making the flanging process smoother and avoiding defects such as material accumulation, wrinkles, or cracks at the flanging position. This guiding effect helps to control the shape and dimensional accuracy of the flanging, making the flanged metal profile 15 meet the design requirements.

[0098] During the stamping process, the part of the metal profile 15 in contact with the lower stamping seat plate 121 will bear a large pressure. The arc-shaped contact surfaces 122 can evenly disperse the pressure generated by stamping to the contact area of the metal profile 15. Compared with planar contact, the arc-shaped contact surfaces 122 increase the contact area with the metal profile 15, thereby reducing the pressure per unit area. This can not only reduce the risk of deformation or damage of the metal profile 15 due to excessive local pressure, but also ensure the uniform distribution of pressure during the flanging process, making the quality of the flanging more stable and consistent.

[0099] The arc-shaped contact surface 122 fits more closely with the metal profile 15, and can better restrain the deformation of the metal material during the flanging process. During the flanging process, the lower end of the metal profile 15 is in close contact with the arc-shaped contact surface 122. The arc shape can help control the angle and radian of the flanging, making the shape of the flanging more regular and beautiful. At the same time, this close fit can also reduce the relative sliding between the metal material and the lower stamping seat plate 121 during the flanging process, further improving the forming quality and precision of the flanging.

[0100] The annular seat 145 is provided with a notch groove for accommodating the second roller 124, and a slope 146 is provided on the side of the notch groove. The second roller 124 rolls to the upper surface of the annular seat 145 via the slope 146.

[0101] When the turntable 143 rotates to drive the annular seat 145 to rotate, the second roller 124 is pushed to roll upward through the slope 146, so that the lower stamping seat plate 121 moves upward, and cooperates with the side stamping part 6 to complete the flanging operation of the metal profile 15.

[0102] When the upper die holder 9 moves downward to stamp the metal profile 15 on the lower stamping seat assembly 12, the auxiliary support assembly 5 drives the transmission assembly 14 to rotate counterclockwise, so that the left and right two sets of side clamping and adjusting parts 13 approach each other to clamp both sides of the metal profile 15. The lower stamping seat assembly 12 moves upward and combines with the downward rotation of the side stamping part 6 to realize the flanging operation of the front and rear ends of the metal profile 15.

[0103] Specifically, during use, the metal profile 15 is placed on the lower stamping seat plate 121. When it is necessary to perform side flanging stamping on the metal profile 15, the hydraulic cylinder 11 is started, and the piston rod 111 of the hydraulic cylinder 11 extends downward to push the upper die holder 9 to move downward. Under the guiding and supporting action of the auxiliary support assembly 5, the upper die holder 9 moves downward stably.

[0104] As the upper die holder 9 moves downward, the inclined support plate 56 in the auxiliary support assembly 5 pushes the abutting wheel 87 of the lower abutting assembly 8, causing the T-shaped seat 81 to move outward. The rack 83 inside the T-shaped seat 81 meshes with the gear 142 in the transmission assembly 14, driving the gear 142 to rotate counterclockwise, and further causing the vertical rotating shaft 141 and the turntable 143 to rotate counterclockwise.

[0105] When the turntable 143 rotates, through the cooperation of the second inclined groove 144 and the vertical pin 132 at the inner end of the clamping arm 131 in the side clamping and adjusting part 13, the left and right two sets of clamping arms 131 approach each other, and the rubber clamping blocks 134 on the clamping plates 133 clamp both sides of the metal profile 15 to prevent the metal profile 15 from moving during the stamping process.

[0106] Meanwhile, when the upper die holder 9 moves downward, the upper stamping seat 10 also moves downward accordingly. Due to the limiting structure between the upper stamping seat 10 and the upper die holder 9 and the action of the buffer spring 104, the upper stamping seat 10 can move downward stably. The upper stamping seat 10 contacts the upper end surface of the metal profile 15 to achieve the pre-pressing and fixing effect on the metal profile 15. Subsequently, when the upper stamping seat 10 is subjected to the resistance of the metal profile 15 and the upper die holder 9 continues to move downward, the upper stamping seat 10 moves upward relative to the upper die holder 9. At this time, through the sliding of the second pin shaft 62 in the first inclined groove 103, the rotating arm 61 is driven to rotate around the first pin shaft 63, causing the stamping head 64 to swing downward, and the stamping head 64 performs downward stamping on the top of the front and rear ends of the metal profile 15, so that the contact part between the lower end of the metal profile 15 and the arc-shaped contact surface 122 undergoes bending deformation, realizing the flanging operation on the front and rear ends of the metal profile 15;

[0107] On the other hand, the rotation of the turntable 143 drives the rotation of the annular seat 145, and the inclined surface 146 on the annular seat 145 pushes the second roller 124 on the lower stamping seat assembly 12 to roll upward, causing the lower stamping seat plate 121 to move upward. The upward movement of the lower stamping seat plate 121 and the downward rotation of the stamping head 64 in the side stamping part 6 together achieve the flanging operation on the front and rear ends of the metal profile 15.

[0108] After stamping is completed, the piston rod 111 of the hydraulic cylinder 11 retracts upward, and the upper die holder 9 moves upward. The lower abutting assembly 8 returns to the initial position under the action of the return spring 85, driving the transmission assembly 14 to rotate reversely, causing the side clamping and adjusting part 13 to release the metal profile 15, and the lower stamping seat assembly 12 moves downward to return to the initial position, preparing for the next stamping.

[0109] When the lower stamping seat plate 121 moves upward and the upper stamping seat 10 moves downward, when the lower stamping seat plate 121 and the upper stamping seat 10 approach each other simultaneously to stamp the metal profile 15, it is equivalent to applying pressure to the metal profile 15 from both the upper and lower directions. This two-way pressure can make the metal profile 15 receive more uniform and stronger forces during the flanging process, thereby enhancing the stamping effect. Compared with applying pressure from only one direction, the two-way pressure can more effectively cause plastic deformation of the metal material, achieve a more thorough flanging operation, and ensure that the depth and angle of the flanging meet the design requirements.

[0110] Since the lower stamping seat plate 121 and the upper stamping seat 10 approach each other simultaneously to stamp the metal profile 15, more stamping actions can be completed within the same time, thereby improving production efficiency. This synchronous stamping method reduces the time waste during the stamping process, shortens the cycle of the entire flanging operation, can complete the processing of products faster, and meets the requirements of large-scale production.

[0111] Double-sided stamping can keep the metal profile 15 more stable during the flanging process. The upper stamping seat 10 pre-compresses and fixes the metal profile 15, while the lower stamping seat plate 121 moves upward to cooperate with the upper stamping seat 10, further enhancing the restraint on the metal profile 15 and reducing the swaying and displacement of the metal profile 15 during stamping. This helps to ensure the position accuracy and dimensional accuracy of the flanging and improve the quality consistency of the product. At the same time, double-sided stamping can also reduce the stress concentration caused by the uneven deformation of the material during stamping, reduce the probability of defects such as cracks and deformations in the product, and improve the reliability and service life of the product.

[0112] For metal profiles 15 with different materials and thicknesses, the stamping method of the simultaneous approach of the lower stamping seat plate 121 and the upper stamping seat 10 has better adaptability. By adjusting the moving speed and pressure magnitude of the lower stamping seat plate 121 and the upper stamping seat 10, the stamping requirements of metal profiles 15 with different materials and thicknesses can be met. For thicker or harder metal materials, double-sided stamping can provide sufficient pressure to cause plastic deformation; for thinner or softer metal materials, double-sided stamping can also precisely control the pressure to avoid excessive deformation or damage of the material, thus expanding the applicable range of the die.

[0113] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
