[0002] Stamping is a processing method that uses molds and stamping equipment to form, shear, bend and other operations on metal sheets. It is suitable for the manufacture of metal parts of various shapes and sizes. The main processes of stamping may include blanking, punching, bending, drawing, flanging, shaping, etc. Among them, drawing is part of the stamping process and is a specific process in the stamping process. Under the action of molds and presses, metal sheets are stretched into parts with three-dimensional shapes, such as automobile body covers (such as engine hoods, doors, etc.), fuel tanks, containers, etc.

[0003] During the drawing process, the material is positioned by the cooperation between the material pressing block and the profile of the blank holder. In order to achieve a close fit between the material pressing block and the profile of the blank holder, in the related art, the material pressing block is directly processed so that it can be closely fitted with the profile of the blank holder to achieve the purpose of pressing, thereby achieving the material pressing positioning. However, the scheme of processing the material pressing block is cumbersome and inefficient. Summary of the invention

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] Stamping is a processing method that uses dies and stamping equipment to form, shear, bend and other operations on metal sheets. It is suitable for the manufacture of metal parts of various shapes and sizes. The main processes of stamping can include blanking, punching, bending, drawing, flanging, shaping, etc.

[0035] Drawing is part of the stamping process and is a specific process in the stamping process. Metal sheets are stretched into parts with three-dimensional shapes under the action of dies and presses, such as automobile body covers (such as engine hoods, doors, etc.), fuel tanks, containers, etc.

[0036] During the drawing process, the material is positioned by the cooperation between the material pressing block and the profile of the blank holder. In order to achieve a close fit between the material pressing block and the profile of the blank holder, in the related art, the material pressing block is directly processed so that it can be closely fitted with the profile of the blank holder to achieve the purpose of pressing, thereby achieving the material pressing positioning. However, the solution of processing the material pressing block requires high processing accuracy and is costly.

[0037] Moreover, due to the different product profiles, the disadvantage of this pressing positioning method is that it cannot be applied to other drawing dies due to its universality and versatility. It is necessary to re-equip and debug the clamping blocks in each set of dies, which increases the mold cost and reduces the universality of standard parts.

[0038] In addition, in the actual application process, the pressing device needs to be continuously debugged to ensure the stability of the driving cylinder, connecting rod and pressing surface, which increases the difficulty of debugging the mold, greatly prolongs the debugging time, and increases the time cost.

[0039] To solve the above problems, according to the first aspect of the present application, referring to Figures 1 to 11 The present disclosure provides a material press. Figure 1 The material press comprises a mounting member 100 and a material press assembly 200. The material press assembly 200 is movably mounted on the mounting member 100 so that the angle between the material press assembly 200 and the mounting member 100 can be adjusted, and the material press assembly 200 is used for pressing materials.

[0040] The pressing assembly 200 and the mounting member 100 can be connected by a universal joint. The universal joint is also called a universal joint, which is a component used to achieve variable angle power transmission and is widely used in locations where the direction of the transmission axis needs to be changed. The "material" in the pressing material mainly refers to the workpiece. Figure 8 , in some embodiments, Figure 8 The workpiece 600 is shown in the figure, wherein the workpiece 600 may be held by the blank holder 700 on one side and pressed by the material pressing assembly 200 on the other side. The workpiece 600 is clamped by the blank holder 700 and the material pressing assembly 200. The workpiece 600 may be a plate. It should be noted that Figures 8 to 11 The workpiece 600 is shown in FIG. Figure 8 and Fig. 9 , the state when the pressing assembly 200 does not press the workpiece 600 is shown. Fig.10 and Fig.11 , the state of the pressing assembly 200 pressing the workpiece 600 is illustrated.

[0041] The blank holder 700 is a component used to prevent the workpiece 600 from wrinkling during the molding process. It can be an annular device arranged around the edge of the workpiece 600, used to fix a part of the workpiece 600 on the mold, thereby controlling the flow of the workpiece 600 and preventing wrinkles or other defects from occurring at the edge of the workpiece 600 during the molding process.

[0042] The press comprises an adjusting assembly, which is at least partially disposed between the mounting member 100 and the press assembly 200, so as to adjust the angle between the press assembly 200 and the mounting member 100. In the present application, the angle between the press assembly 200 and the mounting member 100 is changed by adjusting the assembly, thereby changing the distance between the two ends of the press assembly 200 and the mounting member 100. Since the workpiece 600 is often placed on the side of the press assembly 200 away from the mounting member 100, when the distance between the two ends of the press assembly 200 and the mounting member 100 changes, the distance between the press assembly 200 and the workpiece 600 is also changed.

[0043] Compared with the solution in the related art that needs to directly process the material pressing block so that it can be closely fitted with the profile of the blank pressing ring for pressing, in the present application, the angle between the material pressing assembly 200 and the mounting member 100 is adjustable, so that the material pressing assembly 200 does not need to be processed, and the material pressing can be achieved by adjusting the angle between the material pressing assembly 200 and the mounting member 100. This saves the processing and debugging of the traditional material pressing block, and reduces the processing difficulty and time.

[0044] In some embodiments, the adjustment component includes an elastic adjustment member, which is disposed between the press component 200 and the mounting member 100. In some examples, the elastic adjustment member may include a spring. The elastic adjustment member can well adjust the press component 200 to move smoothly.

[0045] Please combine Figure 1 as well as Figure 2 In some embodiments, the pressing assembly 200 and the mounting member 100 may be arranged along a first direction and connected to the mounting member 100. The pressing assembly 200 and the mounting member 100 may be screwed or clamped together, etc. In some examples, the first direction may be the direction of gravity.

[0046] In some examples, the mounting member 100 may be a pressure plate, which is mainly used to mount an adjustment component.

[0047] Please combine Figure 1In some embodiments, the pressing assembly 200 includes a first end 201 and a second end 203 that are arranged opposite to each other, and the first end 201 and the second end 203 are both used for pressing the material, and the angle between the pressing assembly 200 and the mounting member 100 is adjustable so that one of the first end 201 and the second end 203 moves toward a direction close to the pressing assembly 200, and the other moves toward a direction away from the pressing assembly 200. There is at least one adjustment assembly, and an adjustment assembly is provided between at least one of the first end 201 and the second end 203 and the mounting member 100.

[0048] Please combine Figure 1 In some examples, the first end 201 and the second end 203 may be disposed along the second direction, the first end 201 may be close to or away from the mounting member 100, and the second end 203 may be close to or away from the mounting member 100. In some examples, the second direction may be a horizontal direction.

[0049] The pressing assembly 200 is mainly used to press the workpiece 600 that needs to be drawn. The workpiece 600 that needs to be drawn is located on the side of the pressing assembly 200 away from the mounting member 100. Both sides of the workpiece 600 that needs to be drawn are clamped by the pressing assembly 200 and the blank holder 700. In this process, the first end 201 can be close to or away from the mounting member 100, so that the clamping method of the first end 201 and the workpiece 600 can be changed. The second end 203 can be close to or away from the mounting member 100, so that the clamping method of the second end 203 and the workpiece 600 can be changed. In this way, even if the two sides of the workpiece 600 are tilted or uneven, the workpiece 600 can be well pressed by the first end 201 and the second end 203.

[0050] Specifically, when the pressing assembly 200 contacts the workpiece 600, the first end 201 of the pressing assembly 200 can be pressed by the workpiece 600, so that the first end 201 can be adaptively adjusted, that is, the first end 201 can move an appropriate distance in the direction close to the mounting member 100, so as to better press the workpiece 600.

[0051] When the pressing assembly 200 contacts the workpiece 600 , the second end 203 of the pressing assembly 200 can be pressed by the workpiece 600 , so that the second end 203 can be adaptively adjusted, that is, the second end 203 can move an appropriate distance in the direction close to the mounting member 100 , so as to better press the workpiece 600 .

[0052] Through the cooperation between the first end 201 and the second end 203 of the pressing assembly 200 , the workpiece 600 can be better pressed on both sides.

[0053] In some embodiments, the workpiece 600 can be a plate. The workpiece 600 is placed on the pressure ring 700, and the pressure assembly 200 is driven to move toward the side close to the workpiece 600, so that the first end 201 and the second end 203 press against the workpiece 600, so that the first end 201 and the second end 203 can cooperate with the pressure ring, and the first end 201 and the second end 203 can clamp the workpiece along the second direction.

[0054] In some embodiments, the pressing assembly 200 further includes a first adjusting member 210 and a second adjusting member 220 . The first adjusting member 210 is disposed between the mounting member 100 and the first end 201 , and the second adjusting member 220 is disposed between the mounting member 100 and the second end 203 .

[0055] In this example, the first adjusting member 210 and the second adjusting member 220 are provided to respectively adjust the movement of the first end 201 and the second end 203 , so that the adjustment is more flexible.

[0056] In some examples, the press assembly 200 further includes a first adjusting member 210, and the opposite ends of the first adjusting member 210 are respectively connected to the mounting member 100 and the first end 201. The distance between the mounting member 100 and the first end 201 can be adjusted by the first adjusting member 210, so that the first end 201 moves toward or away from the workpiece 600, so as to press the workpiece 600. And cooperate with the second end 203 to press the workpiece along the second direction. The first adjusting member 210 may include an elastic member, such as an elastic polymer material (such as polyurethane, rubber, etc.), a spring, etc., and further, the first adjusting member 210 may include a rectangular spring.

[0057] In some examples, the press further includes a second adjusting member 220, and opposite ends of the second adjusting member 220 are respectively connected to the mounting member 100 and the second end 203. The distance between the mounting member 100 and the second end 203 can be adjusted by the second adjusting member 220, so that the second end 203 moves toward or away from the workpiece 600, thereby pressing the workpiece 600 and cooperating with the first end 201 to press the workpiece 600 along the second direction. The second adjusting member 220 may include an elastic member, such as an elastic polymer material (such as polyurethane, rubber, etc.), a spring, etc., and further, the second adjusting member 220 may include a rectangular spring.

[0058] In some examples, opposite ends of the first adjusting member 210 are connected to the mounting member 100 and the first end 201, respectively. Meanwhile, opposite ends of the second adjusting member 220 are connected to the mounting member 100 and the second end 203, respectively. The first adjusting member 210 can be used to adjust the distance between the mounting member 100 and the first end 201, thereby causing the first end 201 to move toward or away from the workpiece 600, thereby pressing the workpiece 600. The second adjusting member 220 can be used to adjust the distance between the mounting member 100 and the second end 203, thereby causing the second end 203 to move toward or away from the workpiece 600, thereby pressing the workpiece 600.

[0059] In some embodiments, the first end 201 and the second end 203 are fixedly connected, so that the movement between the first end 201 and the second end 203 is coupled.

[0060] Please combine Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 The pressing assembly 200 has a first state, the mounting member 100 has a first surface 101 facing the pressing assembly 200, the first end 201 has a second surface 202 facing the mounting member 100, and the second end 203 has a third surface 204 facing the mounting member 100. When the pressing assembly is in the first state, the minimum distance between the second surface 202 and the first surface 101 is equal to the minimum distance between the third surface 204 and the first surface 101.

[0061] The first state may include a first sub-state and a second sub-state, wherein the first sub-state may include a free state where the first end 201 and the second end 203 are not subjected to pressure applied by the workpiece 600. Figure 8 as well as Fig. 9 At this time, the first end 201 and the second end 203 are fixedly connected because there is no pressure applied by the workpiece 600 , and the minimum distance between the second surface 202 and the first surface 101 is equal to the minimum distance between the third surface 204 and the first surface 101 .

[0062] In some embodiments, the first adjusting member 210 and the second adjusting member 220 may both include the same spring, the first end 201 and the second end 203 may be two ends of an integral structure, the first end 201 and the second end 203 may be integrally formed, and the structures of the first end 201 and the second end 203 may be the same. Thus, when the pressing assembly 200 is in the first sub-state, the minimum distance between the second surface 202 and the first surface 101 is equal to the minimum distance between the third surface 204 and the first surface 101.

[0063] In some embodiments, when the pressing assembly 200 is in the second sub-state, the workpiece 600 applies equal pressure to the first end 201 and the second end 203, so that the first end 201 and the second end 203 are subjected to equal forces, and the minimum distance between the second surface 202 and the first surface 101 is equal to the minimum distance between the third surface 204 and the first surface 101.

[0064] In some embodiments, the elastic adjusting member is in a compressed state. In some examples, when the pressing assembly is in the first state, both the first adjusting member 210 and the second adjusting member 220 are in a compressed state.

[0065] In some examples, the first adjusting member 210 and the second adjusting member 220 may both include the same spring, the first end 201 and the second end 203 may be two ends of an integral structure, the first end 201 and the second end 203 may be integrally formed, and the structures of the first end 201 and the second end 203 may be the same. When the press assembly 200 is in the first state, the first adjusting member 210 and the second adjusting member 220 are both in a compressed state. At this time, if the workpiece 600 applies different pressures to the first end 201 and the second end 203, the first end 201 and the second end 203 will be subjected to different forces, and the press assembly 200 will switch from the first state to the second state.

[0066] Specifically, please combine Fig.10 as well as Fig.11 When the workpiece 600 is placed on the blank holder, the workpiece 600 is in an inclined state, with one end being high and the other end being low.

[0067] For example, the side of the workpiece 600 close to the first end 201 is higher (the side of the workpiece 600 close to the first end 201 is closer to the mounting member 100), and the side of the workpiece 600 close to the second end 203 is lower (the side of the workpiece 600 close to the second end 203 is farther away from the mounting member 100). At this time, the first end 201 may first contact the workpiece 600 and be subjected to the pressure applied by the workpiece 600. The first adjusting member 210 on the side of the first end 201 will be further compressed, causing the first end 201 to rotate toward the side away from the workpiece 600. At this time, the first end 201 will cooperate with the pressure ring 700 to clamp one end of the workpiece 600. When the second end 203 has not yet contacted the workpiece 600 and is not subjected to the pressure applied by the workpiece 600, since the second end 203 is fixedly connected to the first end 201, the second adjusting member 220 is in a compressed state. Therefore, when the first end 201 rotates toward the side away from the workpiece 600, the second adjusting member 220 will tend to restore its initial free state. That is, the second adjusting member 220 will drive the second end 203 to rotate in a direction close to the workpiece 600, so that it can contact the workpiece 600 and resist the workpiece 600, so that the second end 203 cooperates with the pressure ring to clamp the other end of the workpiece 600 along the second direction.

[0068] For example, the side of the workpiece 600 close to the second end 203 is higher (the side of the workpiece 600 close to the second end 203 is closer to the mounting member 100), and the side of the workpiece 600 close to the first end 201 is lower (the side of the workpiece 600 close to the first end 201 is farther away from the mounting member 100). At this time, the second end 203 may first contact the workpiece 600 and be subjected to the pressure applied by the workpiece 600. At this time, the second end 203 will cooperate with the pressure ring to clamp one end of the workpiece 600, and the second adjustment member 220 on the side of the second end 203 will be further compressed, causing the second end 203 to rotate toward the side away from the workpiece 600. The first end 201 has not yet contacted with the workpiece 600, and is not subjected to the pressure applied by the workpiece 600. However, since the first end 201 is fixedly connected to the second end 203, the first adjusting member 210 is in a compressed state. Therefore, when the second end 203 rotates toward the side away from the workpiece 600, the first adjusting member 210 tends to restore the initial free state, that is, the first adjusting member 210 drives the first end 201 to rotate in the direction close to the workpiece 600, so as to contact with the workpiece 600 and resist the workpiece 600. Thus, the first end 201 cooperates with the blank holder to clamp the other end of the workpiece 600 in the second direction.

[0069] In some embodiments, when the pressing assembly 200 is in the first state, the minimum distance between the second surface 202 and the first surface 101 is L1, and when the pressing assembly is in the second state, the minimum distance between the second surface 202 and the first surface 101 is L2, and the minimum distance between the third surface 204 and the first surface 101 is L3, wherein L2>L1>L3 or L2 <L1<L3。

[0070] In some embodiments, the press assembly 200 further includes a press block 240 and a connecting member 230. The press block 240 includes the first end 201 and the second end 203 described above, and the press block 240 cooperates with the blank holder 700 to clamp the workpiece 600. The first end 201 and the second end 203 are arranged along the second direction, so that the workpiece 600 can be clamped along the second direction.

[0071] The connecting member 230 includes a first connecting portion 231 and a second connecting portion 233 connected to each other. The first connecting portion 231 is connected to the mounting member 100 . The first connecting portion 231 may be screwed to the mounting member 100 .

[0072] Please combine Figure 3, the second connection part 233 is connected to the press block 240, and the second connection part 233 can be screwed with the press block 240, wherein the connection between the second connection part 233 and the press block 240 is located between the first end 201 and the second end 203. The mounting member 100 and the press block 240 are connected by the connecting member 230, and the connection between the second connection part 233 and the press block 240 is located between the first end 201 and the second end 203, so that the first end 201 and the second end 203 can rotate around the connection between the second connection part 233 and the press block 240, thereby realizing the cooperation between the first end 201 and the second end 203 and the blank holder. In some embodiments, the connection between the second connection part 233 and the press block 240 is located in the middle of the first end 201 and the second end 203.

[0073] In some embodiments, when the press assembly 200 includes the first adjusting member 210 and the second adjusting member 220, the first adjusting member 210 and the second adjusting member 220 are symmetrically located on both sides of the connecting member 230, and the first adjusting member 210 and the second adjusting member 220 can be the same structure, and only the first adjusting member 210 is used as an example here to describe its specific structure. In some examples, the first adjusting member 210 can be a push pin joint, and the first adjusting member 210 can specifically include a spring and a push pin, one end of the spring is connected to the mounting member 100, specifically, the mounting member 100 can be provided with a mounting groove facing the side of the press assembly 200, and one end of the spring is installed in the mounting groove of the mounting member 100, and the mounting groove can also guide the movement of the spring. The other end of the spring extends along a side away from the mounting member 100, and is connected to one end of the push pin (the end face of the end can be set to a plane), which can specifically be screwed, welded, sleeved, etc. One end of the ejector pin away from the spring can be set to a round head, and as it approaches the press assembly 200, the cross-sectional area of ​​the ejector pin gradually decreases. In this way, by contacting the press assembly 200 with the round head, it has better directionality. In some examples, one end of the ejector pin away from the spring can move relative to the press assembly 200, that is, there is no actual connection relationship between the one end of the ejector pin away from the spring and the press assembly 200, but only contact with the surface of the press assembly 200, which enables the one end of the ejector pin away from the spring to move freely on the surface of the press assembly 200.

[0074] In some embodiments, the pressing assembly 200 is connected to the mounting member 100 through a universal joint, so that the pressing assembly 200 is movably mounted on the mounting member 100. This allows the pressing assembly 200 to have more movable directions. The universal joint can be a ball cage universal joint, a cross-axis rigid universal joint, etc.

[0085] According to the second aspect of the present disclosure, the present application further provides a drawing die, which includes a driving module 400 and the above-mentioned presser, the driving module 400 is used to drive the presser to cooperate with the blank holder 700 to clamp the workpiece 600, and the drawing die includes the above-mentioned presser. The drawing die has all the above-mentioned beneficial effects, which will not be repeated in this disclosure.

[0086] In some embodiments, the driving module 400 includes a driving member 410 and a mounting seat 420 . The driving member 410 is mounted on the mounting seat 420 . The driving member 410 is drivingly connected to the presser, and the presser is rotatably connected to the mounting seat 420 .

[0087] In some embodiments, the driving member 410 includes a driving cylinder 411 and a cylinder push rod 413, the press also includes a support block 500, the support block 500 is fixedly connected to the shell 300 of the press assembly 200, the driving cylinder 411 is hinged to the mounting seat 420, one end of the cylinder push rod 413 is fixedly connected to the piston of the driving cylinder 411, and the other end of the cylinder push rod 413 is hinged to the support block 500, and the support block 500 is hinged to the upper end of the mounting seat 420.

[0088] In some embodiments, the workpiece 600 may be a plate, and after the press rod pushes the blank holder upward for a certain distance, the workpiece 600 is placed on the blank holder 700. At this time, the driving cylinder 411 driving the blank holder is started, and the cylinder push rod 413 is lifted upward by the driving cylinder 411, thereby driving the support block 500 to rotate, and the blank holder assembly 200 on the support block 500 rotates accordingly.

[0089] In some examples, the drawing die can be a drawing die in which the driving cylinder is arranged longitudinally. The angle between the pressing assembly 200 and the mounting member 100 is adjustable. When the pressing assembly 200 contacts the workpiece 600, the pressing assembly 200, under the influence of the adjusting assembly and the connecting member 230, realizes the function of automatically adjusting and pressing the workpiece 600 through mutual movement, and finally cooperates with the blank holder 700 to clamp the workpiece 600, thereby preventing the workpiece 600 from moving during the drawing process, thereby ensuring the quality of the drawn sheet metal parts. The present application replaces the original manual debugging work with a multi-angle, self-adjusting drawing die, thereby reducing the debugging difficulty of the drawing die and improving the debugging efficiency. The drawing die of the present application can be applied to various types of pressing work without debugging, which greatly improves its universality and versatility.

[0090] Before use, the presser is installed first, and the connecting member 230 can be installed on the mounting member 100 and the press assembly 200 respectively, to ensure that the press assembly 200 can automatically adjust the angle direction of the press assembly 200 as the contact surface of the workpiece 600 changes, and then the adjustment assembly is fixed in the housing 300, and the adjustment assembly is in contact with the mounting member 100 and the press assembly 200 and is in a certain compression state. After the installation is completed, the cylinder push rod 413 is fixed on the piston of the driving cylinder 411, the end of the cylinder push rod 413 is hinged with the end of the support block 500 through a pin, the support block 500 is hinged with the mounting seat 420 through a pin, and finally the driving cylinder 411 is hinged on the mounting seat 420 with a pin.

[0091] When in use, the press is mounted on the corresponding mounting surface of the blank holder 700. When the drawing die is opened, the non-working state is shown in Figure 8 and Fig. 9 , the adjusting components are all in a certain degree of compression state, and the press component 200 and the connecting member 230 are in a free state under the influence of gravity. When the blank holder 700 is pushed upward by the press rod for a certain distance, the workpiece 600 is placed on the blank holder. At this time, the driving cylinder 411 is started, and the cylinder push rod 413 is lifted upward by the driving cylinder 411, thereby driving the support block 500 to rotate, and the support block 500 drives the press to rotate accordingly.

[0092] When the presser contacts the workpiece 600, Fig.10 and Fig.11 , the pressing assembly 200 is subjected to the reaction force of the workpiece 600, and deflects at a certain angle under the action of the connecting member 230, the spring of one adjusting assembly is compressed and deformed, and the spring of the other adjusting assembly is released, generating a certain pre-tightening force, so as to achieve the purpose of fully clamping the workpiece 600 from multiple directions. After the work is completed, the pressing assembly 200 returns to a free state, and the springs of the two adjusting assemblies return to the initial compressed state, preparing for the next work.

[0093] After the work is completed, the pressing assembly 200 returns to a free state, the first adjusting member 210 and the second adjusting member 220 return to their initial compressed states, driving the cylinder 411 back to their original positions, and the pressing device can be rotated and lifted through the connecting rod mechanism to facilitate the picking and placing of parts in preparation for the next work.
