Description

Technical Field

[0001] This application relates to the field of drawing die technology, and in particular to a pressure feeder and a drawing die. Background Technology

[0002] Stamping is a processing method that uses dies and stamping equipment to form, shear, and bend metal sheets, suitable for manufacturing metal parts of various shapes and sizes. The main stamping processes include blanking, punching, bending, drawing, flanging, and shaping. Drawing is a specific step within the stamping process, where metal sheets are stretched into three-dimensional shapes under the action of dies and presses, such as automotive body panels (e.g., engine hoods, doors), fuel tanks, and containers.

[0003] During the drawing process, the clamping block and the blank holder surface cooperate to achieve clamping and positioning. To achieve a tight fit between the clamping block and the blank holder surface, related technologies directly process the clamping block to ensure a close fit and thus achieve clamping and positioning. However, processing the clamping block is cumbersome and inefficient. Summary of the Invention

[0004] This application provides a pressure feeder and a drawing die to at least partially solve the above-mentioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this application, a pressure feeder is provided, comprising:

[0006] Installation components;

[0007] A material clamping assembly, movably mounted on the mounting member such that the included angle between the material clamping assembly and the mounting member is adjustable, the material clamping assembly being used for clamping material; and,

[0008] An adjustment component, at least partially disposed between the mounting component and the pressure component, is provided for adjusting the included angle between the pressure component and the mounting component.

[0009] According to a second aspect of this application, a drawing die is provided, including a drive module and the aforementioned pressure plate, wherein the drive module is used to drive the pressure plate to engage with a blank holder to clamp a workpiece.

[0010] In the pressure device of this application embodiment, the pressure assembly is movably mounted on the mounting member. The included angle between the pressure assembly and the mounting member can be adjusted by an adjusting component to achieve pressure. Compared to related technologies that require direct machining of the pressure block to ensure tight contact with the pressure ring surface, in this application, the included angle between the pressure assembly and the mounting member is adjustable. This eliminates the need for machining the pressure assembly; pressure is achieved simply by adjusting the angle between the pressure assembly and the mounting member, resulting in simple operation and high efficiency.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

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

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

[0036] During the drawing process, the clamping block and the blank holder surface cooperate to achieve clamping and positioning. To achieve a tight fit between the clamping block and the blank holder surface, related technologies directly process the clamping block to ensure a close fit and achieve the clamping purpose, thus realizing clamping and positioning. However, processing the clamping block requires high precision and is costly.

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

[0038] In addition, in practical applications, the pressing device needs to be continuously adjusted to ensure the stability of the drive cylinder, connecting rod and pressing surface. This increases the difficulty of mold adjustment, greatly prolongs the adjustment time and increases time costs.

[0039] To solve the above problems, according to the first aspect of this application, with reference to Figures 1 to 11 This disclosure provides a pressure feeder. Please refer to... Figure 1 The pressure device includes a mounting member 100 and a pressure assembly 200. The pressure assembly 200 is movably mounted on the mounting member 100 such that the included angle between the pressure assembly 200 and the mounting member 100 is adjustable, and the pressure assembly 200 is used for pressure.

[0040] The clamping assembly 200 and the mounting component 100 can be connected via a universal joint. The universal joint, also known as a universal connector, is a machine component used to achieve variable-angle power transmission, widely used in locations where the direction of the transmission shaft needs to be changed. In clamping, "material" primarily refers to the workpiece. Please refer to... Figure 8 In some embodiments, Figure 8 The diagram illustrates workpiece 600, which can be held abutted on one side by a pressure ring 700 and pressed down on the other side by a clamping assembly 200. The workpiece 600 is clamped by the cooperation of the pressure ring 700 and the clamping assembly 200. Workpiece 600 can be a plate. It should be noted that... Figures 8 to 11 The diagram shows workpiece 600. Figure 8 and Figure 9 The diagram illustrates the state when the pressure assembly 200 is not pressing against the workpiece 600. Figure 10 and Figure 11 The image shows the state of the pressing assembly 200 pressing against the workpiece 600.

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

[0042] The pressure feeder includes an adjustment component, which is at least partially disposed between the mounting member 100 and the pressure feed assembly 200, for adjusting the included angle between the pressure feed assembly 200 and the mounting member 100. In this application, by adjusting the component, the included angle between the pressure feed assembly 200 and the mounting member 100 is changed, thereby changing the distance between the two ends of the pressure feed assembly 200 and the mounting member 100. Since the workpiece 600 is often placed on the side of the pressure feed assembly 200 away from the mounting member 100, when the distance between the two ends of the pressure feed assembly 200 and the mounting member 100 changes, the distance between the pressure feed assembly 200 and the workpiece 600 also changes.

[0043] Compared to related technologies that require direct machining of the pressure block to ensure a tight fit with the pressure ring surface, this application features an adjustable angle between the pressure assembly 200 and the mounting component 100. This eliminates the need for machining the pressure assembly 200; pressure is achieved simply by adjusting the angle between the two components. This eliminates the need for machining and adjusting the traditional pressure block, reducing processing difficulty and time.

[0044] In some embodiments, the adjustment assembly includes a resilient adjustment member disposed between the pressure assembly 200 and the mounting member 100. In some examples, the resilient adjustment member may include a spring. The resilient adjustment member effectively regulates the smooth movement of the pressure assembly 200.

[0045] Please combine Figure 1 as well as Figure 2 In some embodiments, the pressing assembly 200 and the mounting member 100 can be arranged along a first direction and connected to the mounting member 100. The connection between the pressing assembly 200 and the mounting member 100 can be screwed, snap-fit, or similar. In some examples, the first direction can be the direction of gravity.

[0046] In some examples, mounting component 100 can be a pressure plate, primarily used for mounting adjustment components.

[0047] Please combine Figure 1In some embodiments, the pressing assembly 200 includes a first end 201 and a second end 203 disposed opposite to each other. Both the first end 201 and the second end 203 are used for pressing materials. The included angle between the pressing assembly 200 and the mounting member 100 is adjustable, such that one of the first end 201 and the second end 203 moves toward the pressing assembly 200, and the other moves away from the pressing assembly 200. At least one adjusting component is provided, and at least one of the first end 201 and the second end 203 is provided between itself and the mounting member 100.

[0048] Please combine Figure 1 In some examples, the first end 201 and the second end 203 can be positioned along a second direction, with the first end 201 approaching or moving away from the mounting member 100, and the second end 203 approaching or moving away from the mounting member 100. In some examples, the second direction can be a horizontal direction.

[0049] The clamping assembly 200 is mainly used to clamp the workpiece 600 that needs to be drawn. The workpiece 600 is located on the side of the clamping assembly 200 away from the mounting member 100. The two sides of the workpiece 600 are clamped by the clamping assembly 200 and the clamping ring 700, respectively. During this process, the first end 201 can move closer to or further away from the mounting member 100, thus changing the clamping method between the first end 201 and the workpiece 600. Similarly, the second end 203 can move closer to or further away from the mounting member 100, thus changing the clamping method between the second end 203 and the workpiece 600. In this way, even if the two sides of the workpiece 600 are tilted or uneven, the first end 201 and the second end 203 can still effectively clamp the workpiece 600.

[0050] Specifically, when the pressing assembly 200 comes into contact with 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 part 100, so as to better press the workpiece 600.

[0051] When the pressure assembly 200 comes into contact with the workpiece 600, the second end 203 of the pressure 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 closer to the mounting part 100, so as to better press the workpiece 600.

[0052] By cooperating with the first end 201 and the second end 203 of the pressing assembly 200, the workpiece 600 can be pressed down better 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 closer to the workpiece 600, so that the first end 201 and the second end 203 press against the workpiece 600, thereby 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, wherein 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, by setting the first adjusting member 210 and the second adjusting member 220, the movement of the first end 201 and the second end 203 are adjusted respectively, making the adjustment more flexible.

[0056] In some examples, the pressure assembly 200 further includes a first adjusting member 210, with its opposite ends connected to the mounting member 100 and the first end 201, respectively. The distance between the mounting member 100 and the first end 201 can be adjusted via the first adjusting member 210, thereby causing the first end 201 to move closer to or further away from the workpiece 600, thus pressing down on the workpiece 600. It also cooperates with the second end 203 to press the workpiece along a second direction. The first adjusting member 210 may include an elastic element, such as an elastic polymer material (e.g., polyurethane, rubber), a spring, etc. Further, the first adjusting member 210 may include a rectangular spring.

[0057] In some examples, the pressure feeder further includes a second adjusting member 220, with its opposite ends connected to the mounting member 100 and the second end 203, respectively. The distance between the mounting member 100 and the second end 203 can be adjusted via the second adjusting member 220, thereby causing the second end 203 to move closer to or further away from the workpiece 600, thus pressing down on the workpiece 600 and cooperating with the first end 201 to compress the workpiece 600 along a second direction. The second adjusting member 220 may include an elastic element, such as an elastic polymer material (e.g., polyurethane, rubber), a spring, etc., and further, the second adjusting member 220 may include a rectangular spring.

[0058] In some examples, the opposite ends of the first adjusting member 210 are connected to the mounting member 100 and the first end 201, respectively. Simultaneously, the opposite ends of the second adjusting member 220 are connected to the mounting member 100 and the second end 203, respectively. The distance between the mounting member 100 and the first end 201 can be adjusted by the first adjusting member 210, thereby causing the first end 201 to move closer to or further away from the workpiece 600, thus pressing down on the workpiece 600. The distance between the mounting member 100 and the second end 203 can be adjusted by the second adjusting member 220, thereby causing the second end 203 to move closer to or further away from the workpiece 600, thus pressing down on the workpiece 600.

[0059] In some embodiments, the first end 201 and the second end 203 are fixedly connected, such that there is a coupling relationship between the movement of the first end 201 and the second end 203.

[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, a first end 201 has a second surface 202 facing the mounting member 100, and a 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 in which the first end 201 and the second end 203 are not subjected to pressure applied by the workpiece 600. Please refer to [the relevant text]. Figure 8 as well as Figure 9 At this time, since the first end 201 and the second end 203 are not subjected to the pressure applied by the workpiece 600, the first end 201 and the second end 203 are fixedly connected, 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 each 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 identical. 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 pressure assembly 200 is in the second sub-state, the workpiece 600 applies equal pressure to the first end 201 and the second end 203, such 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 adjustment member is in a compressed state. In some examples, when the pressure assembly is in the first state, both the first adjustment member 210 and the second adjustment member 220 are in a compressed state.

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

[0066] Specifically, please combine Figure 10 as well as Figure 11 When workpiece 600 is placed on the pressure ring, workpiece 600 is in an inclined state, with one end higher and the other end lower.

[0067] For example, the side of workpiece 600 closer to the first end 201 is higher (the side of workpiece 600 closer to the first end 201 is closer to the mounting member 100), and the side of workpiece 600 closer to the second end 203 is lower (the side of workpiece 600 closer to the second end 203 is further away from the mounting member 100). At this time, the first end 201 may contact the workpiece 600 first and be subjected to the pressure applied by the workpiece 600. The first adjusting member 210 on one 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. Before the second end 203 contacts the workpiece 600 and is subjected to pressure from the workpiece 600, the second adjusting member 220 is in a compressed state because the second end 203 is fixedly connected to the first end 201. Therefore, when the first end 201 rotates toward the side away from the workpiece 600, the second adjusting member 220 tends to return to its initial free state. That is, the second adjusting member 220 drives the second end 203 to rotate in the direction closer to the workpiece 600, so that it can contact the workpiece 600 and press against the workpiece 600, thereby making the second end 203 cooperate with the pressure ring to clamp the other end of the workpiece 600 in the second direction.

[0068] For example, the side of workpiece 600 closer to the second end 203 is higher (the side of workpiece 600 closer to the second end 203 is closer to the mounting part 100), and the side of workpiece 600 closer to the first end 201 is lower (the side of workpiece 600 closer to the first end 201 is further away from the mounting part 100). At this time, the second end 203 may contact the workpiece 600 first 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. The second adjusting member 220 on one 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. While the first end 201 is not yet in contact with the workpiece 600 and is not subjected to pressure from the workpiece 600, since the first end 201 is fixedly connected to the second end 203 and the first adjusting member 210 is in a compressed state, when the second end 203 rotates toward the side away from the workpiece 600, the first adjusting member 210 tends to return to its initial free state. That is, the first adjusting member 210 drives the first end 201 to rotate in the direction closer to the workpiece 600, thereby enabling it to contact the workpiece 600 and press against it. This allows the first end 201 to cooperate with the pressure ring to clamp the other end of the workpiece 600 in the second direction.

[0069] In some embodiments, when the pressure assembly 200 is in a first state, the minimum distance between the second surface 202 and the first surface 101 is L1; when the pressure assembly is in a 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 clamping assembly 200 further includes a clamping block 240 and a connector 230. The clamping block 240 includes the first end 201 and the second end 203 described above. The clamping block 240 cooperates with the clamping ring 700 to clamp the workpiece 600. The first end 201 and the second end 203 are arranged along a second direction, thereby enabling the workpiece 600 to be clamped along the second direction.

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

[0072] Please combine Figure 3The second connecting portion 233 is connected to the pressure block 240. The second connecting portion 233 may be screwed to the pressure block 240, wherein the connection point between the second connecting portion 233 and the pressure block 240 is located between the first end 201 and the second end 203. The mounting member 100 and the pressure block 240 are connected by the connecting member 230. The connection point between the second connecting portion 233 and the pressure block 240, located between the first end 201 and the second end 203, allows the first end 201 and the second end 203 to rotate around the connection point between the second connecting portion 233 and the pressure block 240, thereby achieving the engagement of the first end 201 and the second end 203 with the pressure ring. In some embodiments, the connection point between the second connecting portion 233 and the pressure block 240 is located between the first end 201 and the second end 203.

[0073] In some embodiments, when the pressing assembly 200 includes a first adjusting member 210 and a 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. The first adjusting member 210 and the second adjusting member 220 can have the same structure. Here, only the first adjusting member 210 is used as an example, and its specific structure is described. In some examples, the first adjusting member 210 can be a top pin assembly. Specifically, the first adjusting member 210 can include a spring and a top pin. One end of the spring is connected to the mounting member 100. Specifically, the mounting member 100 can have a mounting groove on the side facing the pressing assembly 200. One end of the spring is installed in the mounting groove of the mounting member 100. The mounting groove can also guide the movement of the spring. The other end of the spring extends along the side away from the mounting member 100 and is connected to one end of the top pin (the end face of which can be set as a plane). Specifically, it can be screwed, welded, sleeved, etc. One end of the top pin separating from the spring can be rounded, and the cross-sectional area of ​​the top pin gradually decreases as it approaches the pressure assembly 200. This rounded head provides better directionality when contacting the pressure assembly 200. In some examples, one end of the top pin separating from the spring can move relative to the pressure assembly 200; that is, there is no actual connection between the end of the top pin separating from the spring and the pressure assembly 200, but only contact with the surface of the pressure assembly 200. This allows the end of the top pin separating from the spring to move freely on the surface of the pressure assembly 200.

[0074] In some embodiments, the clamping assembly 200 is connected to the mounting member 100 via a universal joint, allowing the clamping assembly 200 to be movably mounted on the mounting member 100. This enables the clamping assembly 200 to have more directions of movement. The universal joint can be a ball joint, a cross-type rigid universal joint, etc.

[0075] Specifically, the first connecting part 231 and the second connecting part 233 can be connected by a universal joint.

[0076] In some examples, connector 230 includes a third connecting portion 234, which includes a first shaft 235 and a second shaft 236 fixedly connected and angled together. The plane containing the axis of the first shaft 235 and the axis of the second shaft 236 forms an angle with the extension direction of connector 230. The end of the first connecting portion 231 facing away from the mounting member 100 is rotatably connected to the first shaft 235. The second shaft 236 is rotatably connected to one end of the second connecting portion 233. The end of the second connecting portion 233 facing away from the mounting member 100 is connected to the pressure block 240.

[0077] During operation, the pressure device uses two intersecting shafts, the first shaft 235 and the second shaft 236, to continuously change the relative position of the first connecting part 231 and the second connecting part 233, thereby adjusting the pressure angle of the pressure assembly 200 and achieving the effect of tight pressure.

[0078] In some embodiments, there are multiple clamping assemblies 200, which are arranged on the same side of the mounting member 100. This allows for sufficient clamping of the workpiece 600.

[0079] In some examples, multiple pressure components 200 are arranged along a third direction, which is perpendicular to the second direction and also perpendicular to the first direction. The third direction can be horizontal, and both the third and second directions can be on a horizontal plane, while the first direction is perpendicular to the horizontal plane.

[0080] In some embodiments, an adjustment component is provided between each pressing assembly 200 and the mounting member 100. This allows each pressing assembly 200 to be adjusted individually.

[0081] In some embodiments, the pressure feeder further includes a housing 300, which is connected and fixed to the mounting member 100. The housing 300 has a mounting cavity, and the adjusting assembly and / or the pressure feeding assembly 200 are at least partially disposed within the mounting cavity. The mounting member 100 can be mounted on the housing with screws, and the housing 300 can restrict the movement of the adjusting assembly, allowing the adjusting assembly to move within the housing 300. In some examples, the adjusting assembly is at least partially disposed within the mounting cavity. In some examples, the pressure feeding assembly 200 is at least partially disposed within the mounting cavity. In some examples, both the adjusting assembly and the pressure feeding assembly 200 are at least partially disposed within the mounting cavity.

[0082] In some examples, the housing 300 and the mounting part 100 are arranged along a first direction, the mounting part 100 is connected to the housing 300, and the pressure block 240 is located on the side of the housing 300 away from the mounting part 100. This makes the pressure device more integrated, compact, and aesthetically pleasing.

[0083] In some embodiments, the mounting member 100 is detachably connected to the housing 300, thereby facilitating the installation of the pressure assembly 200. In some examples, the mounting member 100 and the housing 300 may be screwed together.

[0084] In some embodiments, the pressure block 240 is an elastic element. The material of the pressure block 240 can be an elastic polymer material. In some examples, the material of the pressure block 240 can be polyurethane.

[0085] According to a second aspect of this disclosure, this application also provides a drawing die, which includes a drive module 400 and the aforementioned pressure plate. The drive module 400 is used to drive the pressure plate to cooperate with the blank holder 700 to clamp the workpiece 600. The drawing die includes the aforementioned pressure plate. This drawing die has all the aforementioned beneficial effects, which will not be repeated here.

[0086] In some embodiments, the drive module 400 includes a drive member 410 and a mounting base 420. The drive member 410 is mounted on the mounting base 420 and is driven by a pressure feeder. The pressure feeder is rotatably connected to the mounting base 420.

[0087] In some embodiments, the drive unit 410 includes a drive cylinder 411 and a cylinder push rod 413. The pressure device also includes a support block 500, which is fixedly connected to the housing 300 of the pressure assembly 200. The drive cylinder 411 is hinged to the mounting base 420. One end of the cylinder push rod 413 is fixedly connected to the piston of the drive cylinder 411, and the other end of the cylinder push rod 413 is hinged to the support block 500. The support block 500 is hinged to the upper end of the mounting base 420.

[0088] In some embodiments, the workpiece 600 can be a sheet metal. After the press push rod pushes the pressure ring upward a certain distance, the workpiece 600 is placed on the pressure ring 700. At this time, the drive cylinder 411 that drives the pressure device is activated. The cylinder push rod 413 is lifted upward by the action of the drive cylinder 411, thereby driving the support block 500 to rotate. The pressure assembly 200 on the support block 500 rotates accordingly.

[0089] In some examples, the drawing die can be a drawing die with a longitudinally arranged drive cylinder. The included angle between the clamping assembly 200 and the mounting part 100 is adjustable. When the clamping assembly 200 contacts the workpiece 600, under the influence of the adjusting assembly and the connecting part 230, the clamping assembly 200 automatically adjusts and clamps the workpiece 600 through mutual movement, ultimately cooperating with the blank holder 700 to clamp the workpiece 600, preventing the workpiece 600 from shifting during the drawing process, thereby ensuring the quality of the drawn sheet metal part. This application replaces the original manual adjustment work with a multi-angle, self-adjusting drawing die, thereby reducing the difficulty of adjusting the drawing die and improving the efficiency of adjustment. The drawing die of this application can be applied to various clamping operations without adjustment, greatly improving its universality and versatility.

[0090] Before use, install the pressure device. Connector 230 can be installed on mounting part 100 and pressure assembly 200 respectively, ensuring that pressure assembly 200 can automatically adjust its angle and direction as the contact surface of workpiece 600 changes. Then, fix the adjusting assembly in housing 300, ensuring that the adjusting assembly is in contact with mounting part 100 and pressure assembly 200 and under a certain compression state. After installation, fix cylinder push rod 413 to the piston of drive cylinder 411. The end of cylinder push rod 413 is hinged to the end of support block 500 via a pin. Support block 500 is hinged to mounting base 420 via a pin. Finally, hinge drive cylinder 411 to mounting base 420 with a pin.

[0091] When in use, install the pressure plate on the corresponding mounting surface of the pressure ring 700. For the non-operating state when the drawing die is open, please refer to [link / reference needed]. Figure 8 and Figure 9 The adjusting components are all in a certain degree of compression, while the pressing component 200 and the connecting component 230 are in a free state under the influence of gravity. After the pressing ring 700 is pushed upward a certain distance by the press push rod, the workpiece 600 is placed on the pressing ring. At this time, the drive cylinder 411 is activated, and the cylinder push rod 413 is lifted upward by the action of the drive cylinder 411, thereby driving the support block 500 to rotate. The support block 500 drives the pressing device to rotate accordingly.

[0092] When the pressure plate comes into contact with the workpiece 600, such as Figure 10 and Figure 11 The clamping assembly 200 is subjected to the reaction force of the workpiece 600 and deflects at a certain angle under the action of the connecting piece 230. The spring in one adjusting assembly is compressed and deformed, while the spring in the other adjusting assembly is released, generating a certain preload force to completely clamp the workpiece 600 from multiple directions. After the operation is completed, the clamping assembly 200 returns to its free state, and the springs of both adjusting assemblies return to their initial compressed state, preparing for the next operation.

[0093] After the work is completed, the pressing assembly 200 returns to the free state, the first adjusting member 210 and the second adjusting member 220 return to the initial compressed state, the driving cylinder 411 returns to its original position, and the pressing device can be rotated and lifted by the linkage mechanism to facilitate the picking and putting of parts and prepare for the next work.
