Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a reverse side structure for a drawing die. Background Technology

[0002] During sheet metal forming, the lateral force generated by the height difference and undulation of the blank holder surface will cause the blank holder ring to deflect and deform. It is necessary to design the reverse side structure of the drawing die. The design of the reverse side structure of the existing drawing die needs to be based on the shape of the blank holder surface to determine the direction of the lateral force, and then design the reverse side and reverse side direction. The existing reverse side structure is usually designed as a single-sided guide plate in conjunction with the reverse side of the casting body.

[0003] However, this reverse side structure design method not only involves a process of first "identifying and confirming the shape trend", then "determining the direction of lateral force" based on the shape trend, and then "designing the reverse side direction", but this reverse side structure not only occupies a lot of space, but also has a thicker reverse side of the casting body, which will increase the mold's external dimensions and increase the mold's weight. This reverse side is usually designed on the outer periphery of the pressure ring and the die, and the thickness and strength of the reverse side casting must also be guaranteed.

[0004] Therefore, the existing reverse side structure design has problems such as complex design, large space occupation, and excessive mold size and weight. Utility Model Content

[0005] The purpose of this invention is to provide a reverse side structure for drawing dies, which aims to solve the problems of existing reverse side structures having complex designs, large space occupation, and excessive die size and weight.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a reverse side structure for a drawing die is provided, which is applied to the die. The die includes a corresponding upper die and a pressure ring, and includes: a mounting groove, an abutment groove, and a reverse side block. The mounting groove is disposed on the pressure ring; the abutment groove is disposed on the upper die corresponding to the mounting groove; the reverse side block is detachably installed in the mounting groove; wherein, the reverse side block protrudes from the mounting groove, and the abutment groove abuts against the reverse side block.

[0007] Furthermore, the reverse side block is rectangular in shape.

[0008] Furthermore, the reverse side structure also includes a connector, wherein the reverse side block is provided with at least one mounting hole corresponding to the connector, and the connector passes through the mounting hole and is detachably connected to the mounting groove.

[0009] Furthermore, the reverse side block is provided with a disassembly hole, and the disassembly hole is provided with threads.

[0010] Furthermore, oil grooves are provided on both sides of the reverse side block.

[0011] Furthermore, the oil groove protrudes from the mounting groove.

[0012] Furthermore, the oil trough includes two intersecting grooves.

[0013] Furthermore, the reverse side block is a steel reverse side block.

[0014] Furthermore, the mounting groove is annular.

[0015] Furthermore, the mounting groove protrudes from the pressure ring.

[0016] This utility model provides a reverse side structure for a drawing die, applied to the die. The die includes a corresponding upper die and a pressure ring, comprising: an mounting groove, an abutment groove, and a reverse side block. The mounting groove is disposed on the pressure ring; the abutment groove is disposed on the upper die corresponding to the mounting groove; the reverse side block is detachably installed in the mounting groove; wherein, the reverse side block protrudes from the mounting groove, and the abutment groove abuts against the reverse side block. This utility model replaces the existing reverse side structure of a single-sided guide plate with the reverse side of the casting body by using a reverse side block in conjunction with the mounting groove and the abutment groove. The reverse side block is smaller in size, which helps to save space and reduce the overall weight of the die. Moreover, in the design process of the reverse side structure, it is not necessary to design the reverse side and reverse side direction based on the shape of the pressure surface and the direction of the lateral force. Both sides of the reverse side block can resist the lateral force. Thus, by forming a sliding friction pair with the double-sided reverse side block installed in the mounting groove, the mounting groove, and the abutment groove, the double-sided lateral force received during the drawing die operation can be resisted or balanced. The structure is compact and simple in design. Furthermore, the detachable connection makes the reverse side block easy to install and remove. Attached Figure Description

[0039] A drawing die is a mold used to stretch a flat blank into a hollow part with a certain shape. It mainly consists of an upper die, a pressure ring, a blank holder, a die cavity, and a punch. During the operation of the drawing die, the die is often subjected to lateral forces from different directions, so a reverse side structure needs to be designed.

[0040] Combination Figure 1-8 As shown, this utility model provides a reverse side structure for a drawing die, applied to a die. The die includes a corresponding upper die 1 and a pressure ring 4, including: a mounting groove 2, an abutment groove 5, and a reverse side block 3. The mounting groove 2 is disposed on the pressure ring 1; the abutment groove 5 is disposed on the upper die 4 corresponding to the mounting groove 2; the reverse side block 3 is detachably installed in the mounting groove 2; wherein, the reverse side block 3 protrudes from the mounting groove 2, and the abutment groove 5 abuts against the reverse side block 3.

[0041] In this embodiment of the utility model, the reverse side block 3, in conjunction with the mounting groove 2 and the abutment groove 5, replaces the existing reverse side structure of the single-sided guide plate in conjunction with the reverse side of the casting body. The reverse side block 3 is smaller in size, which helps to save space and reduce the overall weight of the mold. Moreover, in the design process of the reverse side structure, there is no need to design the reverse side and reverse side direction based on the shape of the pressure surface and the direction of the lateral force. Both sides of the reverse side block 3 can resist the lateral force. Thus, the double-sided reverse side block 3 installed in the mounting groove 2, together with the mounting groove 2 and the abutment groove 5, form a sliding friction pair, which can resist or balance the double-sided lateral force during the drawing die operation. The structure is compact and the design is simple. In addition, the detachable connection makes the reverse side block 3 easy to install and remove.

[0042] In some embodiments, the reverse side block 3 is rectangular parallelepiped.

[0043] In this embodiment, the reverse side block 3 is in the shape of a cuboid, which can easily form a double reverse side, thereby resisting or balancing the double lateral forces. Moreover, the cuboid is easy to process, which can save processing time and cost.

[0044] In some embodiments, the reverse side structure further includes a connector (not shown), wherein at least one mounting hole 31 corresponding to the connector is provided on the reverse side block 3, and the connector passes through the mounting hole 31 and is detachably connected to the mounting groove 2.

[0045] In this embodiment, a connector is used to connect and install the reverse side block 3 into the mounting groove 2. The detachable connection makes it easy to install and remove the reverse side block 3. Specifically, the connector is a screw, and the screw connection makes the connection between the reverse side block 3 and the mounting groove 2 secure and facilitates disassembly and replacement.

[0046] In some embodiments, the reverse side block 3 is provided with a disassembly hole 32, and the disassembly hole 32 is provided with threads.

[0047] In this embodiment, the disassembly hole 32 is provided with threads, which helps to remove the reverse side block 3 from the mounting groove 2 using tools.

[0048] In some embodiments, oil grooves 33 are provided on both sides of the reverse side block 3.

[0049] In this embodiment, lubricating oil can be stored in the oil tank 33, which provides lubrication to the reverse side block 3, helping the reverse side block 3 to resist or balance the lateral forces on both sides during the drawing die operation.

[0050] Specifically, the oil groove 33 protrudes from the mounting groove 2, which helps to enhance the lubrication effect of the oil groove 33.

[0051] More specifically, the oil groove 33 includes two intersecting grooves 331, which helps to expand the space occupied by the oil groove 33, thereby providing a better lubrication effect and thus better resisting or balancing the lateral forces on both sides of the reverse side block 3.

[0052] In some embodiments, the reverse side block 3 is a steel reverse side block 3.

[0053] In this embodiment, the steel counterweight 3 has high hardness and strength, which makes it effective in resisting or balancing lateral forces on both sides. Specifically, the counterweight 3 is made of 45 steel, which is easy to process and has good overall performance.

[0054] In some embodiments, the mounting groove 2 is annular.

[0055] In this embodiment, the annular mounting groove 2 can provide a certain amount of reserved space for the reverse side block 3, making the installation of the reverse side block 3 simple and quick.

[0056] In some embodiments, the mounting groove 2 protrudes from the pressure ring 1.

[0057] In this embodiment, the mounting groove 2 protrudes from the pressure ring 1, which helps to install the reverse side block 3 and ensures that the reverse side block 3 can better resist or balance the lateral forces on both sides during the drawing die operation.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
