Description

Technical Field

[0001] This application belongs to the field of automotive manufacturing technology, and in particular relates to a progressive die for automotive parts. Background Technology

[0002] Automobile manufacturing is a complex industrial production process, which includes a series of activities from raw material processing to the final assembly of automobile products. During automobile manufacturing, the production of various automobile parts is involved, and the production of automobile parts is inseparable from the corresponding stamping dies.

[0003] The existing utility model patent with authorization announcement number CN217941599U discloses an automotive parts mold. The automotive parts are placed in the lower mold groove of the lower mold. A first hydraulic cylinder is controlled to drive a moving plate downwards towards the upper mold at the bottom, causing the lower mold to stamp the automotive parts. After the automotive parts are stamped, a second hydraulic cylinder is controlled to drive an ejector frame upwards, causing the ejector frame to drive a buffer plate on the top plate upwards. This buffer plate then ejects the formed automotive parts upwards. During this upward ejection, the combination of rubber pads, springs, and telescopic rods provides cushioning, preventing damage to the formed automotive parts caused by shaking of the bottom surface during ejection, thus ensuring the quality of the formed automotive parts.

[0004] While the above technical solution avoids damage to the formed automotive parts caused by the shaking of the bottom surface during the ejection process, thus ensuring the quality of the formed automotive parts, the above technical solution can only perform single-shape forming of automotive parts and lacks a progressive stamping structure that can perform multi-shape forming in a single process. As a result, the transfer of automotive parts between stamping dies in multiple processes will reduce the production efficiency of automotive parts and increase the production cost.

[0005] To address this issue, we propose a progressive die for automotive parts. Utility Model Content

[0006] The purpose of this application is to address the problem in the prior art that the transfer of automotive parts between stamping dies in multiple processes reduces the production efficiency and increases the production cost of automotive parts, and to propose a progressive die for automotive parts.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A progressive die for automotive parts includes a base. A progressive lower die and a guide shell are fixedly connected to the upper surface of the base. Three sets of lower guide sleeves are fixedly connected to the inner wall of the base. A top plate is provided above the base. A pressure plate is provided below the top plate. A progressive upper punch and three sets of guide pillars are fixedly connected to the bottom surface of the top plate. Two return springs are sleeved on the outer surface of each set of guide pillars. Three sets of upper guide sleeves are fixedly connected to the inner wall of the pressure plate.

[0009] Preferably, the right side of the guide shell is fixedly connected to the left side of the progressive lower die, the outer surface of the progressive upper punch is slidably connected to the inside of the pressure plate, the two ends of each return spring are fixedly connected to the bottom surface of the top plate and the top end of the upper guide sleeve, the inside of each set of upper guide sleeves is slidably connected to the outer surface of the guide post, and mounting plates are fixedly connected to the front and back of the base, and the upper surface of each mounting plate has several identical mounting holes.

[0010] Preferably, a connecting shell is provided above the top plate, the bottom surface of the connecting shell is in contact with the upper surface of the top plate, and the inner wall of the connecting shell and the inner wall of the top plate are threaded together with four mounting bolts.

[0011] Preferably, a docking plate is provided above the connecting shell, and the upper surface of the docking plate has a plurality of identical docking holes.

[0012] Preferably, a locking block is fixedly connected to the bottom surface of the docking plate, and the outer surface of the locking block is engaged with the interior of the connecting shell.

[0013] Preferably, the inner wall of the connecting shell is threaded with two threaded push rods, and the ends of the two threaded push rods that are close to each other are in contact with the two sides of the locking block.

[0014] In summary, the technical effects and advantages of this application are as follows:

[0015] Through the cooperation of the base, progressive die, guide shell, lower guide sleeve, top plate, pressure plate, guide post, upper guide sleeve, return spring, and progressive upper punch, the top plate can connect with the external hydraulic telescopic rod structure. The guide post can slide up and down inside the upper guide sleeve, and the progressive upper punch can slide up and down inside the pressure plate. The return spring can elastically connect the top plate and the upper guide sleeve. The guide shell can accurately guide the raw material to be stamped onto the progressive die. When the pressure plate presses against the progressive die, it can first clamp the raw material to be stamped. The connection between the lower guide sleeve and the guide post can increase the progressive die's pressure. The accuracy of the lower die and the progressive upper punch during docking is crucial. Furthermore, the progressive docking structure on the lower die and the progressive upper punch can perform progressive stamping on the raw material as it moves step by step. In this way, multiple shapes of the raw material can be formed in one process, which increases the production efficiency of automotive parts and reduces production costs. This avoids the problem of reduced production efficiency and increased production costs caused by the lack of a progressive stamping structure that can perform multiple shapes in a single process, which would lead to the transfer of automotive parts between stamping dies in multiple processes.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A progressive die for automotive parts includes a base 1. A progressive die 2 and a guide shell 3 are fixedly connected to the upper surface of the base 1. Three sets of lower guide sleeves 4 are fixedly connected to the inner wall of the base 1. The right side of the guide shell 3 is fixedly connected to the left side of the progressive die 2. Mounting plates 11 are fixedly connected to both the front and back of the base 1. Each mounting plate 11 has several identical mounting holes 12 on its upper surface. By setting the mounting holes 12, it is convenient to use external bolts to fix the mounting plate 11 to the external support structure, thereby facilitating the fixation of the position of the progressive die 2.

[0025] A top plate 5 is provided above the base 1, a pressure plate 6 is provided below the top plate 5, and a connecting shell 13 is provided above the top plate 5. The bottom surface of the connecting shell 13 is in contact with the upper surface of the top plate 5. The inner wall of the connecting shell 13 and the inner wall of the top plate 5 are connected by four mounting bolts 14. By setting the mounting bolts 14, the connecting shell 13 can be fixedly installed on the top plate 5, which facilitates the connection of the top plate 5 with the external hydraulic telescopic structure in conjunction with other structures.

[0026] The bottom surface of the top plate 5 is fixedly connected to the progressive upper punch 10 and three sets of guide posts 7. The outer surface of the progressive upper punch 10 is slidably connected to the inside of the pressure plate 6. A docking plate 15 is provided above the connecting shell 13. Several identical docking holes 16 are opened on the upper surface of the docking plate 15. By setting the docking holes 16, the docking plate 15 can be fixedly connected to the external hydraulic telescopic rod structure with external bolts, thereby facilitating the energy transmission of the telescopic end of the external hydraulic telescopic rod.

[0027] Two return springs 9 are fitted on the outer surface of each set of guide posts 7. A locking block 17 is fixedly connected to the bottom surface of the docking plate 15. The outer surface of the locking block 17 is engaged with the inside of the connecting shell 13. By setting the locking block 17, it can be locked into the inside of the connecting shell 13, thereby facilitating the flexible assembly and disassembly of the docking plate 15 and the connecting shell 13.

[0028] Three sets of upper guide sleeves 8 are fixedly connected to the inner wall of the pressure plate 6. The interior of each set of upper guide sleeves 8 is slidably connected to the outer surface of the guide post 7. The two ends of each return spring 9 are fixedly connected to the bottom surface of the top plate 5 and the top end of the upper guide sleeve 8, respectively. The inner wall of the connecting shell 13 is threadedly connected to two threaded push rods 18. The ends of the two threaded push rods 18 that are close to each other are in contact with the two sides of the locking block 17. By setting the threaded push rods 18, they can travel along the inner wall thread of the connecting shell 13 and press against the locking block 17, thereby increasing the stability of the locking block 17 when it is locked into the interior of the connecting shell 13.

[0029] The working principle of this utility model is as follows: In use, the docking plate 15 is fixedly connected to the telescopic end of the external hydraulic telescopic rod using the docking hole 16 and external bolts. Then, the locking block 17 is inserted into the connecting shell 13, and the two threaded push rods 18 are tightened so that the two threaded push rods 18 press against the two sides of the locking block 17 respectively. After ensuring that the lower guide sleeve 4 can smoothly dock with the guide post 7, the mounting plate 11 is fixed below the pressure plate 6 using external bolts and mounting holes 12. Then, the raw material to be stamped is placed into the guide shell 3 and accurately guided onto the progressive lower die 2. Then, the hydraulic telescopic rod above the docking plate 15 extends, and when the pressure plate 6 presses against the progressive lower die 2, the pressure plate 6 first presses the raw material to be stamped, and at the same time... The progressive upper punch 10 slides downward inside the pressure plate 6. The sliding connection between the lower guide sleeve 4 and the guide post 7 increases the accuracy of the connection between the progressive lower die 2 and the progressive upper punch 10. As the raw material to be stamped moves step by step, the progressive connection structures on the progressive lower die 2 and the progressive upper punch 10 respectively perform progressive stamping on the raw material to be stamped. In this way, the multi-shape forming of the raw material to be stamped can be completed in one process, which increases the production efficiency of automotive parts and reduces the production cost. The design of the entire progressive die for automotive parts effectively solves the problem that the lack of a progressive stamping structure that can perform multi-shape forming in a single process leads to the transfer of automotive parts between stamping dies in multiple processes, which reduces the production efficiency of automotive parts and increases the production cost.
