Description

Technical Field

[0001] The utility model relates to the technical field of metal plate processing, in particular to a flatness shaping die. Background Art

[0002] The warping of metal sheets during the forming process is a complex phenomenon, which may be caused by a variety of factors. The metal sheet itself may have large residual stresses, which may not be fully released during the forming process, causing the sheet to warp. At the same time, when tearing or cutting the sheet, the local area may be subjected to a certain degree of tensile stress, causing deformation of some areas, and then the entire sheet is deformed, resulting in local warping. Temperature change is an important external factor that causes the warping of metal sheets. In a high temperature environment, the sheet expands due to heat, generating thermal stress, which causes warping; while in a low temperature environment, the sheet shrinks and generates internal stress, which may also cause deformation. In addition, the deformation of the bending machine bed may also cause the bending radius and bending angle of each part of the sheet to bend to be different, and then form obvious rebound warping deformation after elastic recovery. Uneven mechanical properties of metal sheets may also cause warping. For example, differences in performance parameters such as elastic modulus and yield strength of the material, as well as the unevenness of the internal structure of the material, may lead to uneven residual stress distribution and uneven rebound during the forming process, which in turn causes warping. In the forming process of stamping, flanging, dimple pressing, deep drawing, etc., if the process parameters are not set properly, such as the punching gap is too large, the punching force of the punch is not enough, etc., it may cause the metal sheet to warp. In addition, the rationality of the mold design also directly affects the forming quality of the sheet. Problems such as the mold not having vent holes and improper waste discharge ports may cause the sheet to warp during the forming process.

[0003] In the prior art, flatness shaping equipment is a special equipment used to improve and ensure the flatness of metal sheets or other workpieces, including a series of rollers, clamps or other mechanical devices, which correct the flatness error by applying appropriate force or adjusting the position of the workpiece. For example, the utility model with application number CN202121273057.0 discloses a metal sheet shaping machine, including a base and a hydraulic cylinder, the top of the base is fixedly connected to a bottom plate, and a feeding mechanism is arranged inside the base, and the feeding mechanism includes a processing table, the bottom of the base is fixedly connected to a fixed frame, and both sides of the bottom of the inner wall of the fixed frame are fixedly connected to a hydraulic push rod, and one end of the output shaft of the hydraulic push rod is fixedly connected to the bottom of the processing table. The utility model relates to the field of metal sheet processing technology. After the sheet metal is shaped, the hydraulic push rod drives the processing table to move toward the inside of the base. When the processing table moves to be flush with the inclined plate, the electric telescopic rod is started to drive the push plate to push the metal sheet off the processing table, and the sheet metal falls into the collection frame through the inclined plate for automatic unloading. The operation is simple, the labor in the processing process is reduced, the labor cost is reduced, and the processing efficiency is improved. The above-mentioned shaping machine also has the following problems: it uses the pressing plate to extrude and shape the sheet metal as a whole, so that the sheet metal is prone to deviation during extrusion, and the stability is poor. In addition, the sheet metal will expand around it during the overall extrusion process, which is easy to cause the shape of the sheet metal to change. Utility Model Content

[0034] Please refer to Figure 1-7 As shown, this embodiment provides a flatness shaping mold, including a lower mold assembly 10, an upper mold assembly 20, multiple positioning assemblies 50, and a first adjustment assembly 30;

[0035] Specifically, the lower die assembly 10 includes a lower die base 11 and a lower die plate 12; the lower die plate 12 is fixedly mounted on the top surface of the lower die base 11, and a support platform 13 for supporting the workpiece to be shaped is formed by extending upward from the middle of the upper surface of the lower die plate 12;

[0036] Specifically, the upper mold assembly 20 includes an upper mold base 21 and an upper mold plate 22; the upper mold base 21 is fixedly installed above the lower mold base 11, and the upper mold plate 22 is fixedly installed on the bottom surface of the upper mold base 21; a gap is formed between the bottom surface of the upper mold plate 22 and the top surface of the support platform 13, and the height of the gap is greater than the thickness of the workpiece to be shaped; the upper mold plate 22 is provided with a plurality of first through holes 221 penetrating the upper and lower surfaces thereof; preferably, the upper mold base 21 and the lower mold base 11 are connected by a plurality of connecting columns.

[0037] Specifically, multiple groups of positioning components 50 are arranged around the supporting platform 13, and the multiple groups of positioning components 50 are used to position the four sides of the workpiece to be shaped respectively;

[0038] Specifically, the first adjustment components 30 are respectively installed in the first through holes 221 of the upper template 22, and the first adjustment components 30 are used to press the upwardly raised portion of the workpiece to be shaped down to a preset flat position.

[0039] In this embodiment, on the basis of the above structure, the upper mold plate of the flatness shaping mold of the utility model is fixedly mounted on the bottom surface of the upper mold base 21, and the gap formed between the bottom surface and the top surface of the support platform 13 is used to accommodate the workpiece to be shaped. The height of this gap is greater than the thickness of the workpiece to be shaped, ensuring that the workpiece can be smoothly placed, and the first through hole 221 set on the upper template 22 provides space for the subsequent installation of the first adjustment component 30. Under the action of the first adjustment member 32, the first pressing member 31 in the first adjustment component 30 can accurately press down the upwardly tilted part of the workpiece to reach a preset flat position. In addition, by adjusting the external force of the first adjustment member 32, the downward pressure and position of the pressing member can be accurately controlled, thereby realizing the accurate shaping of the tilted part of the workpiece. This precise control helps to reduce the error in the shaping process and improve the shaping quality. In addition, the multiple positioning components 50 of the utility model can accurately fix the workpiece to be shaped from four directions to ensure its stable position during the shaping process. This positioning method can effectively prevent the workpiece from moving or offsetting during the shaping process, thereby ensuring the accuracy and consistency of the shaping. The design of multiple groups of positioning components 50 enables the shaping mold to adapt to workpieces of different sizes and shapes to be shaped. By adjusting the position of the positioning components 50, it can easily adapt to the needs of various workpieces, thereby improving the versatility and flexibility of the shaping mold.

[0040] In a preferred embodiment of the present invention, the number of the first through holes 221 is multiple, and the number of the first adjustment components 30 is the same as the first through holes and corresponds one to one; the first adjustment component 30 includes a first pressure piece 31 and a first adjustment piece 32, the first pressure piece 31 is installed in the first through hole 221 so as to be movable up and down, and the first adjustment piece 32 is installed on the upper mold base 21, and the first adjustment piece 32 is used to drive the first pressure piece 31 to move in a direction close to the workpiece to be shaped under the action of an external force, so that the first pressure piece 31 can press the upwardly raised part of the workpiece to be shaped down to a preset flat position

[0041] On the basis of the above structure, the utility model sets a plurality of first adjustment components 30, so that the operator can selectively perform local shaping on the warped parts according to the actual situation of the workpiece. This local shaping capability makes the shaping process more flexible and can be accurately adjusted according to the shapes and sizes of different workpieces to meet personalized shaping needs.

[0042] In a preferred embodiment of the present invention, a first threaded hole 211 is provided on the upper die base 21 at a position corresponding to each first through hole 221, and the first threaded hole 211 passes through the upper and lower surfaces of the upper die base 21; the first adjusting member 32 includes a first locking screw, and the first locking screw is threadedly connected to the first threaded hole 211, and the lower end of the first locking screw can pass through the first threaded hole 211 and abut against the upper end of the first pressing member 31, and by tightening the first locking screw downward, the first locking screw can drive the first pressing member 31 to move in a direction close to the workpiece to be shaped, so that the first pressing member 31 can press the upwardly raised portion of the workpiece to be shaped down to a preset flat position.

[0043] On the basis of the above structure, in this embodiment, by providing the first threaded hole 211 and the first locking screw, the operator only needs to simply rotate the first locking screw to achieve the downward pressing action of the first pressing member 31. This threaded connection method not only has a fast adjustment speed, but also has a uniform adjustment force, which can ensure stability and reliability during the shaping process. On the other hand, the direct contact between the first locking screw and the first pressing member 31 allows the operator to accurately control the downward pressure by controlling the rotation degree of the first locking screw. This precise control helps to avoid excessive or insufficient pressure on the workpiece, thereby improving the shaping accuracy.

[0044] In a preferred embodiment of the utility model, a first receiving groove 223 is provided on the inner side wall of each first through hole 221; a stop portion 311 is provided on the side wall of each first pressing member 31, and the first adjustment assembly 30 also includes a first elastic member 33 installed in the first receiving groove 223, the upper end of the first elastic member 33 abuts against the stop portion 311, and the lower end thereof abuts against the bottom surface of the first receiving groove 223.

[0045] On the basis of the above structure, before the shaping operation begins, the first pressing member 31 is in a suspended state due to the support of the first elastic member 33 and will not contact the surface of the workpiece. This avoids the potential scratches or indentations of the first pressing member 31 on the surface of the workpiece due to gravity, and protects the integrity of the surface of the workpiece. During the adjustment process, the operator does not need to worry about the misoperation caused by the weight of the first pressing member 31 itself. The first pressing member 31 remains in a suspended state before adjustment, so that the operator can more accurately control the force and position of its downward pressure, reduce the operation error, and improve the shaping accuracy. After the shaping is completed, the restoring force of the first elastic member 33 can help the pressing member quickly return to the initial position and prepare for the next shaping operation. This not only improves work efficiency, but also reduces the labor intensity of the operator. In addition, the setting of the first accommodating groove 223 and the stopper 311 simplifies the installation process of the first elastic member 33, making the structure of the entire adjustment assembly more compact and easy to maintain. The operator can more conveniently check and replace the first elastic member 33 to ensure the continuous and stable operation of the shaping mold.

[0046] In a preferred embodiment of the present utility model, the lower template 12 is provided with a plurality of second through holes 121 penetrating the upper and lower surfaces thereof; it also includes a plurality of second adjustment components 40, and the plurality of second adjustment components 40 are respectively installed in the plurality of second through holes 121 of the lower template 12, and the second adjustment components 40 include a second pressure piece 41 and a second adjustment piece 42, the second pressure piece 41 is installed in the second through hole 121 so as to be movable up and down, and the second adjustment piece 42 is installed on the lower mold base 11, and the second adjustment piece 42 is used for driving the second pressure piece 41 to move in a direction close to the workpiece to be shaped under the action of an external force, so that the second pressure piece 41 can press the downwardly bent portion of the workpiece to be shaped to a preset flat position.

[0047] On the basis of the above structure, on the basis of the upper template 22 pressing down and shaping the warped part of the workpiece through the first adjustment component 30, the second adjustment component 40 of the lower template 12 can press up and shape the downward bending part of the workpiece. This up and down bidirectional shaping method enables the device to more comprehensively handle various deformation problems of the workpiece, improving the comprehensiveness of the shaping. By combining the first adjustment component 30 and the second adjustment component 40, the device can simultaneously handle the two deformation conditions of the workpiece, namely, the warping and the downward bending. This makes the device more adaptable to workpieces of different shapes and deformation conditions, and can meet more diverse shaping needs.

[0048] Specifically, a second threaded hole 111 is provided on the lower die base 11 at a position corresponding to each second through hole 121, and the second threaded hole 111 passes through the upper and lower surfaces of the lower die base 11; the second adjusting member 42 includes a second locking screw, and the second locking screw is threadedly connected to the second threaded hole 111, and the lower end of the second locking screw can pass through the second threaded hole 111 and abut against the upper end of the second pressing member 41, and by tightening the second locking screw upwards, the second locking screw can drive the second pressing member 41 to move in a direction close to the workpiece to be shaped, so that the second pressing member 41 can press the downwardly bent portion of the workpiece to be shaped to a preset flat position.

[0049] In a preferred embodiment of the present utility model, the positioning assembly 50 includes a vertical connecting block 51, a transverse positioning block 52, a fastening screw 53 and a positioning adjustment screw 54; the transverse positioning block 52 is fixedly installed on the lower end of the vertical connecting block 51 by the fastening screw 53, and a fourth threaded hole 511 is also provided on the vertical connecting block 51, and a third threaded hole 222 is also provided on the upper template 22, and one end of the positioning adjustment screw 54 passes through the fourth threaded hole 511 and is threadedly connected with the third threaded hole 222; one end of the transverse positioning block 52 is inserted between the upper template 22 and the lower template 12, and the transverse positioning block 52 is used to abut against the side of the workpiece to be shaped to achieve positioning.

[0050] On the basis of the above structure, the present embodiment can conveniently change the position of the lateral positioning block 52 by adjusting the positioning adjustment screw 54, thereby realizing rapid positioning of different workpieces. The lateral positioning block 52 is fixedly mounted on the lower end of the vertical connection block 51 by the fastening screw 53. This fixing method ensures the stability of the positioning assembly 50 during the shaping process and prevents the positioning block from shifting due to vibration or external force. The positioning adjustment screw 54 is connected to the third threaded hole 222 through the fourth threaded hole 511, so that the lateral positioning block 52 can accurately adjust its position. In this way, the operator is allowed to fine-tune the position of the positioning block according to the size and shape of the workpiece to be shaped, thereby realizing accurate positioning of the workpiece to be shaped.

[0051] In a preferred embodiment of the present invention, the number of the positioning components 50 is groups, and two groups of positioning components 50 are evenly arranged on each side of the support platform 13 .

[0052] Thus, two sets of positioning components 50 are arranged on each side, which can ensure that the workpiece to be shaped is effectively positioned in four directions on the support platform 13. This all-round positioning method can prevent the workpiece from moving or offsetting during the shaping process, thereby ensuring the stability and accuracy of the shaping process. By evenly arranging the positioning components 50, the workpiece to be shaped can be evenly stressed when subjected to the shaping force, which helps to avoid deformation or damage of the workpiece due to uneven stress, and improves the shaping quality and product consistency.

[0054] In this way, four sets of first adjustment components 30 are arranged at the four corners of the workpiece to be shaped, so that precise control of the corners of the workpiece can be achieved. The corners are usually the key parts in the shaping process. By setting the adjustment components at these positions, the shape and size of the corners can be ensured to achieve the expected shaping effect. The remaining first adjustment components 30 are arranged in the middle of the workpiece to be shaped, which helps to balance the distribution of the shaping force on the workpiece and reduce the deformation caused by uneven force in the middle. At the same time, the middle adjustment component can also fine-tune the local area of ​​the workpiece as needed to improve the accuracy and flexibility of shaping.

[0055] In a preferred embodiment of the present invention, the number of second adjustment components 40 is four to six groups, wherein four groups of second adjustment components 40 are respectively arranged at the four corners of the workpiece to be shaped, and the remaining second adjustment components 40 are arranged in the middle of the workpiece to be shaped.

The corners are usually the key parts in the shaping process. By setting the adjustment components at these positions, the shape and size of the corners can be ensured to achieve the expected shaping effect. The remaining second adjustment components 40 are arranged in the middle of the workpiece to be shaped, which helps to balance the distribution of the shaping force on the workpiece and reduce the deformation caused by uneven force in the middle. At the same time, the second adjustment components 40 in the middle can also fine-tune the local area of ​​the workpiece as needed to improve the accuracy and flexibility of shaping.
