Description

Technical Field

[0001] This utility model belongs to the technical field of stamping die equipment, and specifically relates to a die mechanism for stamping that facilitates loading and unloading. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). Stamping is a process in which pressure is applied to materials at room temperature using dies mounted on a press, causing the materials to separate or plastically deform, thereby obtaining parts of the desired shape.

[0003] In the aerospace industry, most fasteners use a hexagonal internal hole structure. Due to the product structure, the current process of punching hexagonal internal holes suffers from excessively tight contact between the product and the hexagonal fine blank, making it difficult to separate the product from the fine blank and thus affecting the stamping efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a mold mechanism for stamping that facilitates loading and unloading, aiming to solve the problem mentioned in the background art that the product is in too tight contact with the internal six-square fine punch in the current process of punching six-square internal holes, making it difficult to separate the product from the internal six-square fine punch, thus affecting the stamping efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A stamping die mechanism for easy loading and unloading includes a worktable connected to a lower die. The lower die has a receiving hole adapted to a workpiece to be precision stamped. An upper die is located directly above the lower die. The upper die is connected to a precision punch and a drive mechanism. The drive mechanism drives the upper die to carry the precision punch closer to or away from the lower die. A positioning component is slidably connected to the worktable. A loading component is located at the end of the positioning component away from the worktable. A loading component is located at one end of the positioning component. The loading component places the workpiece to be precision stamped onto the positioning component. The workpiece to be precision stamped corresponds to the precision punch.

[0007] As a limitation, the positioning component includes a positioning plate with a positioning groove, the opening of which corresponds to the feeding component. The positioning plate has slide rods at both ends, and the worktable has a slide rail adapted to the slide rod. Each slide rod is fitted with a compression spring, and the two ends of the compression spring abut against the corresponding worktable and the positioning plate.

[0008] As another limitation, the feeding assembly includes a feeding plate with a feeding groove. The opening of the feeding groove corresponds to the opening of the positioning groove. A plurality of parts to be precision punched are provided in the feeding groove. The feeding plate is provided with a plurality of fixing rods. Each fixing rod is close to a corner of the feeding plate. The two ends of each fixing rod are respectively connected to the worktable and the feeding plate. A driving member is provided at the end of the feeding groove away from the opening. The driving member drives each of the parts to be precision punched into the positioning groove.

[0009] As another limitation, the driving component includes a fixed plate connected to the feeding plate. The fixed plate has two compression springs near the positioning plate, located at both ends of the feeding groove. The ends of the two compression springs away from the fixed plate are connected to the driving plate. The driving plate has a driving groove adapted to the workpiece to be precision punched. Positioning rods are provided at both ends of the fixed plate, and the driving plate is slidably connected to the positioning rods.

[0010] As another limitation, the upper surface of the lower mold is provided with a groove, one end of which is connected to the receiving hole, and the opening of the groove faces the feeding assembly.

[0011] As another limitation, the feeding assembly includes a feeding sleeve, the inner diameter of which is larger than the outer diameter of the fine punch and smaller than the outer diameter of the part to be finely punched. The two ends of the feeding sleeve are respectively connected to feeding rods, each feeding rod is slidably connected to a corresponding limiting rod, one end of each limiting rod is connected to the positioning assembly, and each limiting rod is provided with an end cap at the end away from the positioning assembly.

[0012] As another limitation, each of the aforementioned limiting rods has a boss near the end of the positioning component.

[0013] As another limitation, the height of the upper die is greater than the length of the part to be precision stamped.

[0014] As another limitation, the height of the limiting rod is less than the height of the upper mold, but greater than the length of the part to be precision stamped.

[0015] The technological advancements achieved by this invention compared to existing technologies are as follows:

[0016] This utility model relates to a sliding connection positioning assembly for a worktable. The positioning assembly has a feeding component at its end away from the worktable, and a feeding component at one end. The feeding component places the workpiece to be precision-punched onto the positioning assembly, with the workpiece corresponding to the precision punch. The feeding component places the workpiece onto the positioning assembly, and a drive mechanism drives the upper die, carrying the precision punch, through the feeding component, causing the precision punch to contact the workpiece. The mechanism continues to drive the positioning assembly to slide along the worktable, inserting one end of the workpiece into the receiving hole and pressing the positioning assembly against the upper surface of the lower die, thus aligning the precision punch with the workpiece. After the fine blanking part is stamped, the drive mechanism carries the fine punch and the stamped fine blanking part away from the lower die. When the stamped fine blanking part is away from the positioning component, the blanking component detaches the stamped fine blanking part from the fine punch. This solves the problem mentioned in the background art that the current process of punching six-hole internal square holes has excessive contact between the product and the internal six-hole fine punch, making it difficult to separate the product from the internal six-hole fine punch, thus affecting the stamping efficiency. In summary, the present invention adopts the above structure, which makes it easy to separate the stamped fine blanking part from the fine punch, and is suitable for stamping dies.

Detailed Implementation

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] An embodiment of a stamping die mechanism for easy loading and unloading.

[0028] This embodiment discloses a die mechanism for stamping that facilitates loading and unloading, such as... Figure 1 , Figure 2As shown, the assembly includes a worktable 1, which is bolted to a lower die 2. The lower die 2 has a receiving hole 201 formed by the machine tool, which is opened along the thickness direction of the lower die 2. The diameter of the receiving hole 201 is adapted to the workpiece 3 to be precision punched. An upper die 4 is provided directly above the lower die 2. The height of the upper die 4 is greater than the length of the workpiece 3 to be precision punched. This arrangement facilitates the use of the precision punch 5 carried by the upper die 4 to drive the workpiece 3 away from the feeding assembly 8. The side wall of the upper die 4 can prevent the workpiece 3 to be precision punched from coming out of the feeding assembly 8, thus improving the stability of the feeding assembly 8. The upper die 4 can be bolted to the precision punch 5, or it can be connected to the precision punch 5 by a slot. The precision punch 5 is an internal hexagonal precision punch. The fine punch 5 can be an internal square fine punch or an internal triangular fine punch. The upper die 4 is connected to a drive mechanism (not shown in the diagram). The drive mechanism can be hydraulically driven or electrically driven. The drive mechanism drives the upper die 4 to carry the fine punch 5 closer to or away from the lower die 2. A positioning mechanism is provided between the upper die 4 and the worktable 1. The upper die 4 is slidably connected to the positioning mechanism to ensure the positional relationship between the upper die 4 and the lower die 2. The worktable 1 is slidably connected to the positioning component 6. The end of the positioning component 6 away from the worktable 1 is provided with a feeding component 7. One end of the positioning component 6 is provided with a feeding component 8. The feeding component 8 is provided with several parts 3 to be finely punched. The feeding component 8 feeds the parts 3 to be finely punched. The workpiece 3 to be precision punched is placed on the positioning component 6, corresponding to the precision punch head 5. In use, firstly, multiple workpieces 3 to be precision punched are placed in the feeding component 8, with one workpiece 3 positioned within the positioning component 6. Then, the drive mechanism is activated, causing the upper mold 4 to carry the precision punch head 5 through the unloading component 7 to contact the workpiece 3 within the positioning component 6. Next, the drive mechanism causes one end of the workpiece 3 within the positioning component 6 to insert into the receiving hole 201, and the positioning component 6 to press against the upper surface of the lower mold 2. Simultaneously, the sidewall of the upper mold 4 is close to the feeding component 8, preventing the workpiece 3 from detaching from the feeding component 8. Finally, the drive mechanism drives the precision punch head 5 to punch the workpiece 3 within the positioning component 6. After pressing, the drive mechanism carries the fine punch 5 and the stamped fine blank away from the lower die 2, and moves the stamped fine blank away from the positioning component 6. At the same time, the positioning component 6 slides to connect with the worktable 1 and returns to its original position. The feeding component 8 places another fine blank 3 to be finely stamped in the positioning component 6. Finally, the unloading component 7 makes the stamped fine blank detach from the fine punch 5. This solves the problem mentioned in the background art that the current process of stamping internal hexagonal holes has excessive contact between the product and the internal hexagonal fine punch, making it difficult to separate the product from the internal hexagonal fine punch, thus affecting the stamping efficiency. The stamping of one fine blank 3 is completed. Therefore, the advantage of this embodiment is that by adopting the above setting, the stamped fine blank can be easily separated from the fine punch 5.

[0029] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the positioning component 6 includes a positioning plate 601. The positioning plate 601 has a positioning groove 602 formed by the machine tool. The opening of the positioning groove 602 corresponds to the feeding component 8. The two ends of the positioning plate 601 are fixedly connected to the slide rods 603 by welding. There can be two slide rods 603 or four slide rods 603. The worktable 1 has a slide rail 604 formed by the machine tool. The slide rail 604 is set along the height direction of the worktable 1. The slide rail 604 is adapted to the slide rods 603. Under the drive of external force, the slide rods 603 reciprocate within the slide rail 604. Sliding, each slide rod 603 is fitted with a compression spring 605. The two ends of the compression spring 605 respectively abut against the corresponding worktable 1 and positioning plate 601. The height of the slide rod 603 is greater than the length of the compression spring 605 in its natural state. When the drive mechanism drives the positioning plate 601 closer to the lower mold 2, the compression spring 605 is compressed. When the drive mechanism moves away from the lower mold 2, the compression spring 605 returns to its original state, driving the positioning plate 601 away from the lower mold 2 and closer to the feeding assembly 8. The feeding assembly 8 places the part to be finely stamped 3 on the positioning plate 601.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 6As shown, the feeding assembly 8 includes a feeding plate 801, which has a feeding groove 802 cut into it by a machine tool. The opening of the feeding groove 802 corresponds to the opening of the positioning groove 602. Multiple parts 3 to be precision punched are placed in the feeding groove 802. Multiple fixing rods 803 are fixedly connected to the feeding plate 801 by welding. The fixing rods 803 are located near the corners of the feeding plate 801. The other ends of the fixing rods 803 are fixedly connected to the worktable 1 by welding. A driving component is provided at the end of the feeding groove 802 away from the opening. 804, the driving component 804 drives the workpiece 3 to be precision-punched into the positioning groove 602. The driving component 804 includes a fixed plate 80401, which is fixedly connected to the feeding plate 801 by welding. Two compression springs 80402 are fixedly connected to the fixed plate 80401 near the positioning plate 601 by welding. The two compression springs 80402 are located at both ends of the feeding groove 802. The ends of the two compression springs 80402 away from the fixed plate 80401 are fixedly connected to the driving component by welding. Plate 80403, the drive plate 80403 has a drive groove 80404 cut by the machine tool, the drive groove 80404 is adapted to the workpiece 3 to be finely punched. The two ends of the fixed plate 80401 are fixedly connected to the positioning rod 80405 by welding respectively. The drive plate 80403 is slidably connected to the positioning rod 80405. When multiple workpieces 3 to be finely punched are placed in the feeding groove 802, the two compression springs 80402 are compressed. When the workpieces 3 to be finely punched in the positioning assembly 6 are completed and move away from the positioning assembly 6 with the upper mold 4, the compression springs 80402 are compressed. Spring 2 80402 drives drive plate 80401 to place another blank 3 to be precision punched near positioning component 6 onto positioning component 6, completing the automatic feeding of blank 3; the upper surface of lower mold 2 is provided with slide groove 202 by machine tool, one end of slide groove 202 is connected to receiving hole 201, the opening of slide groove 202 faces feeding component 8, the end of blank 3 near lower mold 2 is located in slide groove 202, which improves the positioning of blank 3 and avoids the probability of blank 3 wobbling left and right near the end of lower mold 2.

[0031] like Figure 1 , Figure 6As shown, the unloading assembly 7 includes an unloading sleeve 701. The inner diameter of the unloading sleeve 701 is larger than the outer diameter of the precision punch 5, which facilitates the precision punch 5 to punch the workpiece 3 to be precision punched through the unloading sleeve 701. The inner diameter of the unloading sleeve 701 is smaller than the outer diameter of the workpiece 3 to be precision punched, which facilitates the unloading sleeve 701 to drive the punched workpiece to detach from the precision punch 5 to complete automatic unloading. Both ends of the unloading sleeve 701 are fixedly connected to one end of the unloading rod 702 by welding. The other end of the unloading rod 702 is slidably connected to the corresponding limiting rod 703. The limiting rod 703 is fixedly connected to the positioning assembly 6 by welding. The end of each limiting rod 703 near the positioning assembly 6 is fixedly connected to the boss 704 by welding. The height of the boss 704 is greater than the height of the workpiece 3 to be precision punched at the top of the positioning assembly 4. The setting of the boss 704 facilitates the placement of the first workpiece 3 to be precision punched. On the positioning component 6, each limiting rod 703 is threadedly connected to the end cap 705 at the end away from the positioning component 6. The height of the limiting rod 703 is less than the height of the upper mold 4 and greater than the length of the part to be precision-stamped 3. After the precision punch 5 completes the stamping, it carries the stamped precision-stamped part and the unloading component 7 away from the lower mold 2 under the drive of the drive mechanism. When the stamped precision-stamped part is away from the positioning component 6, the loading component 8 places the next part to be precision-stamped 3 on the positioning component 6. When the unloading rod 702 slides along the limiting rod 703 to the end cap 705, the unloading rod 702 carrying the unloading sleeve 701 stops sliding upward. The drive mechanism continues to drive the precision punch 5 to move upward carrying the stamped precision-stamped part. At this time, the unloading sleeve 701 applies a downward force to the stamped precision-stamped part, driving the stamped precision-stamped part to detach from the precision punch 5 to complete the automatic unloading.

[0032] The working principle of this utility model embodiment is as follows:

[0033] In use, firstly, multiple blanks 3 to be precision punched are placed in the feeding assembly 8, with one blank 3 positioned in the positioning assembly 6. Then, the drive mechanism is activated, causing the upper mold 4 to carry the precision punch 5 through the unloading assembly 7 to contact the blank 3 in the positioning assembly 6. After that, the drive mechanism causes one end of the blank 3 in the positioning assembly 6 to be precision punched into the receiving hole 201, and the positioning assembly 6 to press against the upper surface of the lower mold 2. At the same time, the side wall of the upper mold 4 is close to the feeding assembly 8 to prevent the blank 3 in the feeding assembly 8 from coming out. Then, the drive mechanism causes the precision punch 5 to punch the blank 3 in the positioning assembly 6. After that, the drive mechanism carries the precision punch 5 and the punched blank away from the lower mold 2, and moves the punched blank away from the positioning assembly 6. At the same time, the positioning assembly 6 slides to connect with the worktable 1 and returns to its original position. The feeding assembly 8 places another blank 3 to be precision punched in the positioning assembly 6. Finally, the unloading assembly 7 causes the punched blank to detach from the precision punch 5.
