Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular 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 the processing method of bending the material into a certain angle or shape along a certain curve or straight line on the side of the blank. In layman's terms, it is to fold the side part of the flat blank through the action of the stamping die to form a structure with a specific shape and function.

[0003] When performing side flanging stamping operations on metal profiles, it is difficult for traditional molds to effectively fix the metal profiles during the stamping process. Metal profiles tend to move left and right during stamping, resulting in inaccurate flanging positions, which greatly affects product quality and reduces the product qualification rate. Existing molds can usually only achieve simple stamping actions, and the clamping, stamping, and flanging operations of metal profiles require corresponding equipment to be performed separately, and it is impossible to perform efficient flanging operations on the front and rear ends of the metal profiles at the same time. It often requires multiple operations or complex process conversions to complete the flanging, which not only consumes a lot of time, but also seriously affects production efficiency and is difficult to meet the needs of large-scale production.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example

[0020] See also Figure 1-18 , the present invention provides a technical solution: A side flanging adjustment stamping die comprises a stamping table 1, a leg 3 is 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 a supporting platform for the entire die. The legs 3 provided at the bottom of the stamping table 1 play a supporting role, and 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 force during the stamping process, and ensure the stability of the die during operation.

[0021] A cross frame 4 and a lower die seat 7 located between the cross frames 4 are provided at the upper end of the stamping table 1, and an upper die seat 9 driven by a hydraulic cylinder 11 is provided below the cross frame 4; the hydraulic cylinder 11 is fixed to the middle part of the upper end of the cross frame 4, and the piston rod 111 at the bottom output end of the hydraulic cylinder 11 penetrates the cross frame 4 and is fixedly connected to the middle part of the upper end of the upper die seat 9.

[0022] An upper punch seat 10 is provided inside the upper die seat 9, and a receiving groove 93 for accommodating the upper part of the upper punch seat 10 is provided at the lower end of the upper die seat 9, and a limiting groove 94 is centrally provided on the four side walls of the receiving groove 93. Limiting blocks 101 are provided on the tops of the four side walls of the upper punch seat 10, and the limiting blocks 101 are slidably connected in the corresponding limiting grooves 94. This limiting structure enables the upper punch seat 10 to only slide along the direction of the limiting grooves 94 in the upper die seat 9, thereby ensuring the stability and accuracy of the movement of the upper punch seat 10.

[0023] The upper end of the upper punch 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 on the upper punch seat 10 during the punching process, reduce the wear of the mold, extend the service life of the mold, and improve the quality of the stamping parts to avoid deformation or damage of the stamping parts due to excessive impact force.

[0024] The front and rear ends of the upper die seat 9 and the upper punch seat 10 are connected with side punching parts 6; The side stamping part 6 includes 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; Two left and right groups of first slots 91 are respectively provided at the bottom of the front and rear ends of the upper die seat 9, the first pin shaft 63 arranged on the upper part of the rotating arm 61 is connected to the connecting hole 92 in the corresponding first slot 91, and two left and right groups of second slots 102 are respectively provided at the top of the front and rear ends of the upper stamping seat 10, and a first inclined slot 103 is provided on the side wall of the second slot 102, and both ends of the second pin shaft 62 connected to the top of the rotating arm 61 are inserted into the corresponding first inclined slots 103.

[0025] This connection structure allows the upper punching seat 10 to move upward relative to the upper die seat 9 during the stamping process, and the second pin shaft 62 can slide in the first inclined groove 103 to drive the rotating arm 61 to rotate around the first pin shaft 63, thereby realizing the swing of the punching head 64, and facilitating the flanging operation of the front and rear ends of the metal profile 15.

[0026] When the hydraulic cylinder 11 is started, the piston rod 111 extends downward, pushing the upper die seat 9 to move downward. The upper punch seat 10 inside the upper die seat 9 moves downward together with the upper die seat 9. In this process, the upper punch seat 10 gradually approaches the metal profile 15 placed on the lower punch seat plate 121. Since the upper punch seat 10 and the upper die seat 9 are limited by the limit block 101 and the limit groove 94, and the buffer spring 104 is connected, the upper punch seat 10 can maintain a stable motion trajectory and accurately contact the upper end surface of the metal profile 15.

[0027] Generation of preload force: After the upper punch seat 10 contacts the upper end surface of the metal profile 15, as the upper die seat 9 continues to move downward, the upper punch 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 produces 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, so that the upper punch seat 10 applies a gradually increasing pre-compression force to the metal profile 15. The size of this pre-compression force can be controlled by adjusting the stiffness and initial compression amount of the buffer spring 104 to meet the pre-compression requirements of metal profiles 15 of different materials and thicknesses.

[0028] Pre-tensioned and fixed stable holding: During the stamping process, the upper stamping seat 10 continuously applies a pre-compression force to the metal profile 15 to ensure that the metal profile 15 does not move forward and backward during the flanging operation. At the same time, the friction between the upper stamping seat 10 and the metal profile 15 further enhances the fixing effect. Since the lower end surface of the upper stamping seat 10 is in close contact with the upper end surface of the metal profile 15, the magnitude of the friction force is proportional to the pre-compression force, so a larger pre-compression force can generate a larger friction force, effectively preventing the metal profile 15 from sliding in the horizontal direction.

[0029] The synergy between pre-tightening and subsequent flanging: Cooperation with side stamping 6: After the upper punch seat 10 pre-tightens and fixes the metal profile 15, the upper die seat 9 continues to move downward, and the upper punch seat 10 moves upward relative to the upper die seat 9. The second pin 62 slides in the first inclined groove 103, driving the rotating arm 61 to rotate around the first pin 63, causing the punch head 64 to swing downward. Since the metal profile 15 has been pre-tightened and fixed by the upper punch seat 10, the punch head 64 can accurately punch downward on the top of the front and rear ends of the metal profile 15, causing the lower end of the metal profile 15 to bend and deform at the contact point with the arc-shaped contact surface 122, thereby achieving precise flanging operation. If the upper punch seat 10 is not pre-tightened and fixed, the metal profile 15 may be displaced under the action of the punch head 64, resulting in inaccurate flanging position, affecting product quality.

[0030] Cooperation with the lower punch seat assembly 12: The rotation of the turntable 143 drives the annular seat 145 to rotate, and the inclined surface 146 on the annular seat 145 pushes the second roller 124 in the lower stamping seat assembly 12 to roll upward, so that the lower stamping seat plate 121 moves upward. The pre-tightening and fixing effect of the upper stamping seat 10 ensures the stability of the metal profile 15 in the process of 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 with the lower stamping seat plate 121, and cooperate with the punch head 64 in the side stamping part 6 to achieve the flanging operation of the front and rear ends of the metal profile 15. If the metal profile 15 is not pre-tightened 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 wrinkles, cracks and other problems during the flanging process.

[0031] The importance of pre-tightening: In the side flanging stamping operation, the pre-tightening and fixing effect of the upper stamping seat 10 on the metal profile 15 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 cause problems such as inconsistent flanging dimensions, flanging angle deviation, and uneven surface, which seriously affects the product's qualification rate and performance.

[0032] The left and right sides of the upper die base 9 are connected to the vertical part of the horizontal frame 4 by auxiliary support components 5; The auxiliary support assembly 5 includes an integrally formed horizontal plate 51 centrally connected to the left and right sides of the top of the upper mold base 9, a T-shaped slider 52 connected to the end of the horizontal plate 51, a sleeve frame 53 connected to the outside of the T-shaped slider 52, and an auxiliary support wheel 55 movably connected to the sleeve frame 53 using a U-shaped seat 54; 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 support plate 56; A T-shaped slot 41 for slidingly connecting the T-shaped slider 52 is disposed on the inner wall of the vertical portion of the horizontal frame 4 . The sleeve frame 53 is sleeved on the outer side of the vertical portion of the horizontal frame 4 , and the auxiliary support wheel 55 is closely attached to the side wall of the vertical portion of the horizontal frame 4 .

[0033] The lower end of the horizontal plate 51 is connected and fixed to the bottom side of the upper die seat 9 by a diagonal support plate 56, which enhances the stability of the connection between the horizontal plate 51 and the upper die seat 9. A T-shaped slide groove 41 for sliding the T-shaped slider 52 is provided on the inner wall of the vertical part of the horizontal frame 4, and the sleeve frame 53 is sleeved on the outer side of the vertical part of the horizontal frame 4, and the auxiliary support wheel 55 is close 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 slide groove 41 provides precise guidance for the up and down movement of the upper die seat 9, ensuring the straightness of the movement of the upper die seat 9. The auxiliary support wheel 55 further enhances the stability of the upper die seat 9 during the movement, reduces shaking and deviation, and improves the accuracy of stamping.

[0034] The left and right sides of the lower die base 7 are provided with side clamping adjustment parts 13 and a lower abutment assembly 8 distributed up and down, and the top of the lower abutment assembly 8 contacts the lower end of the auxiliary support assembly 5 (this contact relationship enables the movement of the auxiliary support assembly 5 to be transmitted to the lower abutment assembly 8 during the stamping process, thereby driving the subsequent transmission assembly 14 to move.), and a lower stamping seat assembly 12 is provided above the lower die base 7; The lower abutment assembly 8 includes a T-shaped seat 81, an abutment 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 inner side of the T-shaped seat 81; The top of the abutting wheel 87 is located in the inclined slide groove 561 at the lower end of the inclined support plate 56; The rack 83 extends into the interior of the lower die base 7 through the lower reserved groove 71 at the bottom of the lower die base 7 .

[0035] A row of first rollers 82 are disposed at the front and rear of the T-shaped seat 81 , and the bottom of the first rollers 82 is located on the upper surface of the punching table 1 , which reduces the friction force when the T-shaped seat 81 moves and makes the movement smoother.

[0036] 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 , thereby enhancing the stability of the vertical plate 86 .

[0037] The outer end of the T-shaped seat 81 is provided with a polished rod 84, and a return spring 85 is sleeved on the polished rod 84. The polished rod 84 is inserted into the reserved through hole at the bottom of the cross frame 4, and the outer end of the return spring 85 is connected to the spring receiving slot 42 on the inner side of the bottom of the cross frame 4. The return spring 85 can return the T-shaped seat 81 to the initial position after the stamping is completed, so as to prepare for the next stamping.

[0038] When the auxiliary support assembly 5 moves downward with the upper die seat 9, the movement of the inclined support plate 56 pushes the abutment wheel 87 to move through the inclined slide groove 561, thereby driving the T-shaped seat 81 to move. The rack 83 extends into the interior of the lower die seat 7 through the lower reserved groove 71 at the bottom of the lower die seat 7, and is used for meshing transmission with the transmission assembly 14.

[0039] A transmission assembly 14 is centrally disposed inside the lower die seat 7, two sets of side clamping adjustment members 13 are movably connected to the top of the transmission assembly 14, two sets of lower abutment assemblies 8 are meshedly connected to the lower portion of the transmission assembly 14, and the bottom of the lower punch seat assembly 12 is supported on the top of the transmission assembly 14; The transmission assembly 14 includes a vertical shaft 141, a rotating disk 143 connected to the top of the vertical shaft 141, an annular seat 145 disposed at the upper end of the rotating disk 143, and a gear 142 fixed at the lower part of the vertical shaft 141; The lower end of the vertical rotating shaft 141 is inserted into the rotating shaft reserved hole at the upper end of the punching table 1, so that the gear 142 is located on the upper end surface of the punching table 1, and the gear 142 is meshed between the front and rear sets of racks 83. This meshing structure enables the gear 142 to rotate when the rack 83 moves with the T-shaped seat 81, thereby driving the vertical rotating shaft 141 and the turntable 143 to rotate.

[0040] The side clamping adjustment member 13 includes a clamping arm 131, a clamping plate 133 fixed on the top of the outer end of the clamping arm 131, and a rubber clamping block 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 mold base 7 through the upper reserved groove 72 on the side of the lower mold base 7, and the vertical pin 132 on the inner end of the clamping arm 131 is connected to the corresponding second inclined groove 144 on the turntable 143.

[0041] When the turntable 143 rotates, the second inclined slot 144 cooperates with the vertical pin 132 to make the clamp arm 131 move linearly, thereby realizing the clamping and loosening of the clamp plate 133 on both sides of the metal profile 15. The rubber clamp block 134 can increase the friction between the clamp plate 133 and the metal profile 15, while avoiding damage to the surface of the metal profile 15. The rubber clamp block 134 can contact the metal profile 15 to produce deformation, and when the clamp plate 133 is clamped on both sides of the metal profile 15, the punch head 64, the upper punch seat 10 and the lower punch seat plate 121 can gradually reach the state as shown in FIG. Fig.18 The state shown in which the front and rear ends of the metal profile 15 are flanging; During the stamping process, the position stability of the metal profile 15 directly affects the accuracy of the flanging. The metal profile 15 is clamped on both sides by the rubber clamp 134, which can ensure that the metal profile 15 remains in a fixed position during the downward rotation of the punch head 64 and the upward movement of the lower punching seat plate 121, so that the position, angle and size of the flanging can be accurately carried out according to the design requirements, thereby improving the accuracy and consistency of the flanging operation.

[0042] 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 effective clamping, the movement of the metal profile 15 is prevented, the occurrence 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 mold, reduce abnormal wear and damage to the mold due to the movement of the metal profile, and extend the service life of the mold.

[0043] The lower punch seat assembly 12 includes a lower punch seat plate 121, rectangular limit posts 123 provided at four corners of the lower end of the lower punch seat plate 121, and a second roller 124 movably connected to the lower end of the lower punch seat plate 121 by two sets of front and rear connecting seats 125; The rectangular limiting column 123 is inserted into the corresponding corner inside the lower die base 7 to limit the position of the lower punching seat plate 121 to ensure its stability and accuracy during the up and down movement.

[0044] The front and rear ends of the lower punching seat plate 121 are both provided with arc-shaped contact surfaces 122 to facilitate better fitting with the metal profile 15 .

[0045] The arc-shaped contact surface 122 can provide a smooth guiding path for the flow of the metal material. When the metal material is subjected to pressure, it will flow and extend along the shape of the arc-shaped contact surface 122, making the flanging process smoother and avoiding defects such as accumulation, wrinkles or cracks in the flanging. This guiding effect helps to control the shape and dimensional accuracy of the flanging, so that the metal profile 15 after flanging meets the design requirements.

[0046] During the stamping process, the part where the metal profile 15 contacts the lower stamping seat plate 121 will be subjected to greater pressure. The arc-shaped contact surface 122 can evenly disperse the pressure generated by stamping to the contact area of ​​the metal profile 15. Compared with the flat contact, the arc-shaped contact surface 122 increases 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.

[0047] The arcuate contact surface 122 fits more closely with the metal profile 15, which 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 arcuate contact surface 122, and the arc shape can help control the angle and curvature 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 molding quality and precision of the flanging.

[0048] The annular seat 145 is provided with a notch groove for accommodating the second roller 124 , and a slope 146 is provided on a side of the notch groove. The second roller 124 rolls to the upper end surface of the annular seat 145 via the slope 146 .

[0049] When the rotating disk 143 rotates to drive the annular seat 145 to rotate, the second roller 124 is pushed to roll upward through the inclined surface 146, so that the lower stamping seat plate 121 moves upward, and cooperates with the side stamping piece 6 to complete the flanging operation of the metal profile 15.

[0050] When the upper die seat 9 moves downward to stamp the metal profile 15 on the lower punch seat assembly 12, the auxiliary support assembly 5 drives the transmission assembly 14 to rotate counterclockwise, so that the left and right sets of side clamping adjustment parts 13 are close to each other to clamp the two sides of the metal profile 15, and the lower punch seat assembly 12 moves upward and combines with the downward rotation of the side punching part 6 to realize the flanging operation of the front and rear ends of the metal profile 15.

[0051] Specifically, when in use, the metal profile 15 is placed on the lower punching seat plate 121. When the metal profile 15 needs to be subjected to side flanging punching, the hydraulic cylinder 11 is started, and the piston rod 111 of the hydraulic cylinder 11 extends downward to push the upper die seat 9 to move downward. Under the guidance and support of the auxiliary support assembly 5, the upper die seat 9 moves downward stably.

[0052] As the upper die seat 9 moves downward, the diagonal support plate 56 in the auxiliary support assembly 5 pushes the abutment wheel 87 of the lower abutment assembly 8, so that the T-shaped seat 81 moves 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, thereby causing the vertical shaft 141 and the rotating disk 143 to rotate counterclockwise.

[0053] When the turntable 143 rotates, the left and right groups of clamp arms 131 are brought closer to each other through the cooperation of the second inclined slot 144 and the vertical pin 132 at the inner end of the clamp arm 131 in the side clamping adjustment member 13, and the rubber clamp block 134 on the clamp plate 133 clamps the two sides of the metal profile 15 to prevent the metal profile 15 from moving during the stamping process.

[0054] At the same time, when the upper die seat 9 moves downward, the upper punch seat 10 also moves downward. Due to the limiting structure between the upper punch seat 10 and the upper die seat 9 and the action of the buffer spring 104, the upper punch seat 10 can move downward stably. The upper punch seat 10 contacts the upper end surface of the metal profile 15 to achieve the pre-tightening and fixing effect on the metal profile 15. Subsequently, the upper punch seat 10 is subjected to the resistance of the metal profile 15. When the upper die seat 9 continues to move downward, the upper punch seat 10 moves upward relative to the upper die seat 9. At this time, the second pin shaft 62 slides in the first inclined groove 103, driving the rotating arm 61 to rotate around the first pin shaft 63, causing the punch head 64 to swing downward, and the punch head 64 punches downward on the top of the front and rear ends of the metal profile 15, so that the contact between the lower end of the metal profile 15 and the arc contact surface 122 is bent and deformed, thereby realizing the flanging operation of the front and rear ends of the metal profile 15; On the other hand, the rotation of the turntable 143 drives the annular seat 145 to rotate, and the inclined surface 146 on the annular seat 145 pushes the second roller 124 in the lower punch seat assembly 12 to roll upward, so that the lower punch seat plate 121 moves upward. The lower punch seat plate 121 moves upward and combines with the downward rotation of the punch head 64 in the side punching member 6 to achieve the flanging operation of the front and rear ends of the metal profile 15.

[0055] After the stamping is completed, the piston rod 111 of the hydraulic cylinder 11 retracts upward, and the upper die seat 9 moves upward. The lower abutment assembly 8 returns to the initial position under the action of the return spring 85, driving the transmission assembly 14 to rotate in the opposite direction, so that the side clamping adjustment member 13 releases the metal profile 15, and the lower stamping seat assembly 12 moves downward back to the initial position, ready for the next stamping.

[0056] When the lower punching seat plate 121 moves upward and the upper punching seat 10 moves downward, the lower punching seat plate 121 and the upper punching seat 10 are both close to each other to punch the metal profile 15, which is equivalent to applying pressure to the metal profile 15 from both the upper and lower directions. This bidirectional pressure can make the metal profile 15 receive more uniform and stronger force during the flanging process, thereby enhancing the stamping effect. Compared with applying pressure from only one direction, bidirectional pressure can more effectively cause the metal material to undergo plastic deformation, achieve a more thorough flanging operation, and ensure that the depth and angle of the flanging meet the design requirements.

[0057] Since the lower punching seat plate 121 and the upper punching seat 10 are close to punch the metal profile 15 at the same time, more punching actions can be completed in the same time, thereby improving production efficiency. This synchronous punching method reduces the time waste in the punching process, shortens the cycle of the entire flanging operation, and can complete the product processing faster to meet the needs of large-scale production.

[0058] Bidirectional stamping can make the metal profile 15 maintain better stability during the flanging process. The upper stamping seat 10 pre-tightens and fixes the metal profile 15, and the lower stamping seat plate 121 moves upward to cooperate with the upper stamping seat 10, further enhancing the restraining effect on the metal profile 15 and reducing the shaking and displacement of the metal profile 15 during the stamping process. 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, bidirectional stamping can also reduce the stress concentration caused by the uneven deformation of the material during the stamping process, reduce the probability of defects such as cracks and deformation in the product, and improve the reliability and service life of the product.

[0059] For metal profiles 15 of different materials and thicknesses, the stamping method in which the lower stamping seat plate 121 and the upper stamping seat 10 are close to each other at the same time has better adaptability. By adjusting the moving speed and pressure of the lower stamping seat plate 121 and the upper stamping seat 10, the stamping requirements of metal profiles 15 of different materials and thicknesses can be met. For thicker or harder metal materials, bidirectional stamping can provide sufficient pressure to cause plastic deformation; for thinner or softer metal materials, bidirectional stamping can also avoid excessive deformation or damage of the material by accurately controlling the pressure, thereby expanding the application range of the mold.
