Description

Technical Field

[0001] This utility model relates to the field of stamping forming die technology, and in particular to a multi-station stamping forming die for an oil tank body. Background Technology

[0002] A stamping die is a type of equipment that, under the pressure of a stamping machine, uses the specific shape and structure of the die's working parts to plastically deform, separate, or form sheet metal or other blanks, thereby obtaining stamped parts with specific shapes, dimensions, and properties. It is an indispensable key piece of equipment in stamping production, and its design and manufacturing quality directly affect the precision, production efficiency, and production cost of stamped parts. It is widely used in various industrial fields such as automotive, electronics, and aerospace.

[0003] For example, Chinese Patent Publication No. CN217252103U discloses a stamping die, including an upper die, which includes a pressure block with vertical stroke and a first driving rod and a second driving rod disposed on both sides of the pressure block. The first driving rod and the second driving rod are each provided with a driving surface on the side facing each other. The pressure block is used to drive the target workpiece to undergo elastic deformation and be misaligned. The lower die includes an ejector block and a first bending die and a second bending die slidably disposed on both sides of the ejector block. The first bending die, the second bending die and the ejector block form a receiving space for placing the target workpiece. When the first driving rod and the second driving rod move downward, the driving surface abuts against the first bending die and the second bending die, thereby driving the first bending die and the second bending die to move in the direction closer to the receiving space to stamp the target workpiece.

[0004] In the stamping process of fuel tank bodies, the tank components need to be sequentially conveyed to various stamping dies for processing. To achieve this process, multiple drive units are required to drive each upper die to complete the pressing and closing action. While this technical solution ensures the smooth operation of the stamping process, the increased number of drive units inevitably drives up the overall purchase cost of the stamping equipment. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where the increased number of drive components drives up the overall purchase cost of stamping equipment, and to propose a multi-station stamping forming mold for oil tank bodies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-station stamping forming mold for an oil tank body, including a stamping table, several modular stamping forming molds are arranged above the stamping table, a mounting frame is fixedly installed on one side of the stamping table, an electric cylinder is fixedly connected to one side of the mounting frame, a drive plate is fixedly connected to the drive rod of the electric cylinder, the drive plate is fixedly connected to one side of the drive end in a modular stamping forming mold by bolts, and transmission plates are fixedly connected to both sides of the drive plate by bolts, one end of the transmission plate is fixedly connected to one side of the drive end in an adjacent modular stamping forming mold.

[0007] Preferably, the modular stamping forming die includes a mounting base plate, a lower die, and an upper die. The lower die is fixedly mounted on one side of the mounting base plate, and the upper die is positioned directly above the lower die. The drive plate and the transmission plate are respectively fixedly connected to one side of the upper die in the corresponding modular stamping forming die.

[0008] Preferably, guide rods are fixedly connected to the four corners of the mounting base plate, and one end of each of the four guide rods moves through the four corners of the upper mold.

[0009] Preferably, positioning plates are fixedly connected to both sides of the mounting base plate, and positioning holes are opened at both ends of the two positioning plates.

[0010] Preferably, long plates are fixedly connected to both sides of the stamping table.

[0011] Preferably, a number of positioning rods are fixedly connected to one side of the long plate, and one end of the positioning rods is movably inserted through the interior of the positioning hole.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the other side of the drive plate is fixedly connected to one side of the upper mold in the modular stamping forming mold directly below it, and then two transmission plates are fixedly connected to both sides of the drive plate, so that a single electric cylinder can simultaneously drive three sets of modular stamping forming molds to perform stamping forming, thereby reducing the equipment cost of stamping box parts.

[0013] 2. In this invention, the positioning rod is aligned with the positioning hole, with one end passing through the interior of the positioning hole, allowing the positioning rod to fully position the mounting base plate. This design significantly improves the accuracy and stability of mold installation, effectively avoiding dimensional errors and shape defects in stamped parts caused by installation deviations, and reducing the scrap rate. Simultaneously, the standardized positioning structure makes mold replacement more convenient and efficient, greatly shortening equipment downtime and improving production efficiency.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figures 1-4 As shown, this utility model provides a multi-station stamping forming mold for an oil tank body, including a stamping table 1. Several modular stamping forming molds 2 are arranged above the stamping table 1. A mounting bracket 3 is fixedly installed on one side of the stamping table 1. An electric cylinder 4 is fixedly connected to one side of the mounting bracket 3. A drive plate 41 is fixedly connected to the drive rod of the electric cylinder 4. The drive plate 41 is fixedly connected to one side of the drive end of a modular stamping forming mold 2 by bolts. Transmission plates 42 are fixedly connected to both sides of the drive plate 41 by bolts. One end of the transmission plate 42 is fixedly connected to... The modular stamping die 2 is connected to one side of the drive end in the adjacent modular stamping die 2. The modular stamping die 2 includes a mounting base plate 21, a lower die 22 and an upper die 23. The lower die 22 is fixedly installed on one side of the mounting base plate 21, and the upper die 23 is located directly above the lower die 22. The drive plate 41 and the transmission plate 42 are respectively fixedly connected to one side of the upper die 23 in the corresponding modular stamping die 2. Guide rods 24 are fixedly connected to the four corners of the mounting base plate 21, and one end of each of the four guide rods 24 moves through the four corners of the upper die 23.

[0019] The specific settings and functions of this embodiment are described below. Based on the stamping requirements of the housing component, a corresponding modular stamping die 2 is selected and placed above the stamping table 1. The drive rod of the electric cylinder 4 is then fixedly connected to the drive plate 41. The other side of the drive plate 41 is fixedly connected to one side of the upper die 23 in the modular stamping die 2 directly below it. Subsequently, two transmission plates 42 are fixedly connected to both sides of the drive plate 41, allowing a single electric cylinder 4 to simultaneously drive three sets of modular stamping dies 2 for stamping, reducing the equipment cost for stamping housing components. The housing component is placed inside the first set of modular stamping dies 2 for stamping. After stamping, it is placed inside the next set of modular stamping dies 2, and a new housing component is taken and placed inside the first set of modular stamping dies 2 for stamping again. This process is repeated until stamping is complete. When the upper die 23 in the modular stamping die 2 presses downwards, the guide rod 24 constrains the movement trajectory of the upper die 23, preventing tilting and deviation.

[0020] Example 2: Figures 1-4 As shown, the multi-station stamping forming mold for the fuel tank body in this utility model includes a stamping table 1, with several modular stamping forming molds 2 arranged above the stamping table 1. A mounting bracket 3 is fixedly installed on one side of the stamping table 1, and an electric cylinder 4 is fixedly connected to one side of the mounting bracket 3. The drive rod of the electric cylinder 4 is fixedly connected to a drive plate 41. The drive plate 41 is fixedly connected to one side of the drive end of a modular stamping forming mold 2 by bolts. Transmission plates 42 are fixedly connected to both sides of the drive plate 41 by bolts. One end of the transmission plate 42 is fixedly connected to one side of the drive end of an adjacent modular stamping forming mold 2. The modular stamping forming process... The mold 2 includes a mounting base plate 21, a lower mold 22, and an upper mold 23. The lower mold 22 is fixedly mounted on one side of the mounting base plate 21, and the upper mold 23 is positioned directly above the lower mold 22. The drive plate 41 and the transmission plate 42 are respectively fixedly connected to one side of the upper mold 23 in the corresponding modular stamping mold 2. Positioning plates 211 are fixedly connected to both sides of the mounting base plate 21. Positioning holes 212 are opened at both ends of the two positioning plates 211. Long plates 11 are fixedly connected to both sides of the stamping table 1. Several positioning rods 12 are fixedly connected to one side of the long plate 11. One end of the positioning rod 12 moves through the interior of the positioning hole 212.

[0021] The overall effect of this embodiment is that when placing the modular stamping die 2, aligning the positioning rod 12 with the positioning hole 212, with one end passing through the interior of the positioning hole 212, allows the positioning rod 12 to fully position the mounting base plate 21. This design significantly improves the accuracy and stability of die installation, effectively avoiding dimensional errors and shape defects in stamped parts caused by installation deviations, and reducing the scrap rate. Simultaneously, the standardized positioning structure makes die replacement more convenient and efficient, greatly shortening equipment downtime and improving production efficiency.

[0022] The usage method and working principle of this device are as follows: Select the appropriate modular stamping die 2 according to the stamping requirements of the box component, and place it above the stamping table 1. Then, fix the drive rod of the electric cylinder 4 to the drive plate 41. Fix the other side of the drive plate 41 to one side of the upper die 23 in the modular stamping die 2 directly below it. Then, fix the two transmission plates 42 to both sides of the drive plate 41. Place the box component inside the first set of modular stamping dies 2 for stamping. After stamping, place it inside the next set of modular stamping dies 2, and take out a new box component and place it inside the first set of modular stamping dies 2 for stamping again. Repeat the above steps until stamping is completed.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
