Description

Technical Field

[0001] This utility model relates to the field of automotive mold technology, specifically to a rotating material support structure for a steel plate blanking mold. Background Technology

[0002] Existing automotive sheet blanking dies mostly employ fixed support brackets or complex hinged support mechanisms for material support. Fixed support brackets are rigidly welded or bolted to the lower die base. These structures cannot be folded or stored, and the overall size of the die is extremely large, occupying significant storage space in the workshop and severely restricting the flexibility of production line layout. While complex hinged support mechanisms can reduce space usage by allowing for angular adjustment via hinges, they rely on multiple sets of precisely fitted shafts, connecting rods, and locking bolts. Assembly requires repeated calibration, which is time-consuming and labor-intensive. Furthermore, over long-term use, wear inevitably occurs on these precision components, leading to increased gaps between parts and poor stability. Frequent maintenance and repairs by operators are needed to maintain accuracy, further increasing maintenance costs. Secondly, in the context of multi-variety, small-batch production, frequent disassembly and assembly of molds are often required. However, the two existing material support structures mentioned above require the additional disassembly of a large number of parts during the mold disassembly and assembly process. After the switch is completed, time is required to readjust and reassemble. It is difficult to quickly adapt and adjust to meet the current demand for rapid mold change production, which greatly reduces the efficiency of production operations. Utility Model Content

[0005] Preferably, the bottom wall of the working trough is provided with a horizontal resting surface, the material support arm rotates and abuts against the horizontal resting surface to maintain a horizontal state, and the rotation angle is limited by the horizontal resting surface in the horizontal state.

[0006] Preferably, the side wall of the receiving groove is provided with a vertical stop surface that is perpendicular to the horizontal resting surface, and the vertical stop surface is used to limit the rotation angle of the material support arm when it is in a vertical state.

[0007] Preferably, both the horizontal docking surface and the vertical stop surface are configured as planes.

[0008] Preferably, when the material support arm is located in the storage groove, the material support arm is in a non-contact state with the bottom wall of the storage groove.

[0012] Preferably, the sliding waist hole is an oblong hole, and the length of the sliding waist hole is greater than the diameter of the pin, so as to provide adjustment margin for horizontal and vertical displacement.

[0013] Preferably, the pin is configured as a T-shaped pin, the free end of the T-shaped pin is threaded, the T-shaped pin passes through the sliding waist hole and the base, and the free end of the T-shaped pin is threadedly connected by a lock nut.

[0014] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0015] (1) This utility model provides a rotating material support structure for a steel plate blanking die. Its structure is simple, easy to implement, and low in cost, solving the problems of large volume, complex assembly, and difficulty in quick adaptation and adjustment of existing material support structures. This utility model mainly includes three parts: a base, a material support arm, and a pin. It is simple to manufacture and disassemble, significantly shortens the manufacturing time and effectively reduces production costs. It can quickly disassemble and switch molds for transformation, and the later maintenance is extremely low. Only simple grinding or direct replacement of the material support arm and pin is required. Secondly, the rotating material support structure's support arm can switch between two states. First, it can rotate into the working slot on the pin to maintain a horizontal position and unfold the support arm, so as to cooperate with the lower mold base to horizontally and evenly support the material plate parts, preventing tilting during the processing of the material plate parts, improving stability and accuracy. The support arm can also be adjusted by sliding the waist hole to adapt to material plate parts of different widths and sizes. Second, the support arm can rotate into the storage slot to maintain a vertical position. That is, the support arm reduces the overall space occupied by vertical storage. In the vertical position, it can be further vertically retracted by sliding the waist hole to reduce space occupation, greatly improving the utilization rate of workshop space.

[0016] (2) In this technical solution, the horizontal resting surface of the working groove can provide a rigid support reference for the material support arm, ensuring that the material support arm is not easy to shake during the stamping process, improving the positioning accuracy of the material plate and the stamping stability, and ensuring product quality.

[0017] (3) In this technical solution, both the horizontal stopping surface and the vertical stopping surface adopt a planar design, that is, the plane has a more uniform limiting contact area with the material support arm, which can effectively reduce local stress concentration, extend the service life of the base and the material support arm, and at the same time reduce the processing accuracy requirements and prevent the material support arm from vibrating due to uneven force.

[0018] (4) In this technical solution, the material support arm and the bottom wall of the storage tank are in a non-contact state. In this way, when the material support arm is stored vertically, it can be suspended in the storage tank, avoiding the friction between the material support arm and the bottom of the storage tank to cause scratches or wear. Secondly, the non-contact method ensures the surface smoothness for long-term use and also has a certain degree of assembly and adjustment flexibility, that is, it can effectively assemble a complete material support structure even if different lengths of material support arms are replaced, and the interchangeability is extremely strong.

[0019] (5) In this technical solution, the sliding waist hole adopts an elongated hole design, which can give the material support arm flexible position adjustment capability, and the elongated hole has a higher compatibility with the pin, and the sliding waist hole moves more smoothly on the pin.

[0037] Please see Figures 1 to 7 .

[0038] This embodiment provides a rotating material support structure for a steel sheet blanking die. Its structure is simple, easy to implement, and low in cost, solving the problems of large size, complex assembly, and difficulty in rapid adaptation and adjustment of existing material support structures. The rotating material support structure in this embodiment is mainly applicable to the processing of automotive steel sheet blanking dies. See [link to relevant documentation]. Figure 1 and Figure 2 The rotating material support structure is mounted on the lower die base X and is used to support sheet metal parts with the lower die base X. The rotating material support structure includes a base 1, a material support arm 2, and a pin; wherein,

[0039] Base 1, which is fixed to the lower mold base X; see [link / reference] Figure 3 The base 1 is provided with a working slot 11 and a storage slot 12 that are interconnected, and the working slot 11 and the storage slot 12 form an "L"-shaped active area.

[0040] Material support arm 2, see Figure 4 and Figure 5It is located within the activity area; the material support arm 2 is provided with a sliding waist hole 21 extending along its length direction, and the extension direction of the sliding waist hole 21 is consistent with the length direction of the material support arm 2; the sliding waist hole 21 is an oblong hole or a rectangular strip hole, etc.

[0041] For example, see the latch. Figure 3 It is a long, round strip, with the axis of the pin perpendicular to the extension direction of the material support arm 2. The pin passes through the sliding waist hole 21 and is fixedly connected to the base 1 to confine the material support arm 2 within the active area; see also Figure 4 and Figure 5 The length of the sliding waist hole 21 is greater than the diameter of the pin. The setting of the sliding waist hole 21 allows the material support arm 2 to have adjustment margins for horizontal and vertical displacement on the pin through the sliding waist hole 21.

[0042] When the material support arm 2 moves, see [the diagram]. Figure 5 and Figure 7 It can rotate around the pin into the working slot 11 or the storage slot 12; see Figure 5 When the material support arm 2 is located inside the working groove 11, the material support arm 2 is in a horizontal state and can move horizontally within the working groove 11 of the base 1 through the sliding waist hole 21; see Figure 7 When the material support arm 2 is located in the storage groove 12, the material support arm 2 is in a vertical state and can be vertically displaced in the storage groove 12 of the base 1 through the sliding waist hole 21.

[0043] In this embodiment, the height of the material support arm 2 in the horizontal state is equal to the height of the support surface of the lower mold base X used to support and place the material plate parts.

[0044] In this embodiment, see Figure 3 The bottom wall of the working trough 11 is provided with a horizontal resting surface 11a. The horizontal resting surface 11a is flat, and the material support arm 2 can rotate and abut against the horizontal resting surface 11a to maintain a horizontal state. The horizontal resting surface 11a is flat, which ensures that the material support arm 2 and the bottom wall of the working trough 11 can stick to each other to maintain horizontal balance and not tilt. Secondly, the horizontal resting surface 11a can also restrict the rotation of the material support arm 2, effectively preventing the material support arm 2 from rotating and affecting the supporting effect of the material plate parts.

[0045] In this embodiment, see Figure 3The side wall of the receiving groove 12 is provided with a vertical stop surface 12a that is perpendicular to the horizontal resting surface 11a. The vertical stop surface 12a is planar and is used to limit the rotation angle of the material support arm 2 in the vertical state. In practice, when the rotating material support structure is installed on the lower mold base X, the lower mold base X is provided with a baffle. This baffle is located next to the base 1. That is, when the material support arm 2 is located in the receiving groove 12, the material support arm 2 is also located between the baffle and the vertical stop surface 12a. In this way, the material support arm 2 cannot rotate significantly to the left or right under the action of the baffle and the vertical stop surface 12a and can only be located in the receiving groove 12. Secondly, in this embodiment, the function of the vertical stop surface 12a is also to ensure that the material support arm 2 can slide vertically against its surface when sliding. In this embodiment, the vertical state of the material support arm 2 is an approximately vertical state relative to the horizontal plane.

[0046] In this embodiment, see Figure 6 and Figure 7 When the material support arm 2 is located within the receiving groove 12, it is in a non-contact state with the bottom wall of the receiving groove 12. That is, the material support arm 2 is suspended above the receiving groove 12 without contacting its bottom wall. This provides the material support arm 2 with a certain sliding space relative to the bottom wall of the receiving groove 12, preventing it from hitting the bottom wall and rubbing against it during vertical displacement above the groove. Furthermore, this sliding space allows the structure to accommodate material support arms 2 of different lengths; that is, by replacing the material support arm 2 with one of different lengths, larger material plate parts can be accommodated.

[0047] In this embodiment, both the working groove 11 and the receiving groove 12 are located in the middle of the base 1. This symmetrical and centrally positioned layout ensures that the mold and the material support arm 2 are subjected to uniform force, avoiding deformation of the base 1 and the material support arm 2 caused by uneven loading. It also simplifies the processing of the base 1 and reduces manufacturing costs. Furthermore, the working groove 11 and the receiving groove 12 have two sidewalls that limit the material support arm 2, effectively preventing it from shifting in either direction. In other embodiments, the working groove 11 and the receiving groove 12 can also be directly positioned to the side (leftmost or rightmost) of the base 1. While such a working groove 11 and the receiving groove 12 can also be used for horizontal placement and vertical storage of the material support arm 2, it lacks a sidewall for limiting the material support arm 2, thus the limiting effect on the material support arm 2 is not optimal.

[0048] In this embodiment, the feeding end of the material support arm 2 is provided with a chamfer 22. The chamfer 22 design can ensure that the material plate parts can smoothly transition into and out of the lower mold base X, reduce the risk of scratches, and improve production efficiency and material plate surface quality.

[0049] The working principle and usage process of this utility model:

[0050] See Figure 1 and Figure 2 In this embodiment, there are four rotating material support structures, with two distributed on the left and right sides of the lower mold base X.

[0051] See Figures 3 to 5 The rotating material support structure includes a base 1, a material support arm 2, and a pin. During installation, the pin passes through the sliding waist hole 21 of the material support arm 2 and is fixedly inserted into the hole of the base 1. In this way, the material support arm 2 is limited to the active area of ​​the base 1, which has extremely high installation efficiency and does not require too much precise positioning.

[0052] When the mold needs to hold the material plate part, see [reference needed]. Figure 5 Rotate each material support arm 2 into the working groove 11 to maintain its working state, that is, one end of the side wall of the material support arm 2 abuts against the horizontal resting surface 11a to maintain a horizontal state; then, the horizontal displacement of the material support arm 2 can be controlled according to the size of the material plate part; see Figure 2 Then, the material plate part is first placed at the chamfered angle 22 position of the material support arm 2, and the material plate part is pushed to slide above the lower mold base X until the material support arms 2 at both ends support the material plate part. In this way, the material plate part remains horizontal under the action of the lower mold base X and the material support arm 2.

[0053] See Figure 7 After the material plate parts have finished unloading, the material support arm 2 is rotated and rests against the side wall of the receiving groove 12. The material support arm 2 is also controlled to move vertically for storage. In this way, the height and space occupancy of the entire rotating material support structure are reduced, making it easier to remove the material plate parts and transfer the mold to other positions. Therefore, this utility model mainly includes three parts: base 1, material support arm 2, and pin. It is simple to manufacture and disassemble, significantly shortens the manufacturing time and effectively reduces production costs. It can quickly disassemble and switch molds, and the later maintenance is extremely low, requiring only simple grinding or direct replacement of the material support arm 2 and the pin. Secondly, the rotating material support arm 2 can switch between two states. First, it can rotate into the working slot 11 on the pin to maintain a horizontal state and unfold the material support arm 2, so as to cooperate with the lower mold base X to horizontally and evenly support the material plate parts, prevent the material plate parts from tilting during processing, and improve stability and accuracy. The material support arm 2 can also be adjusted by sliding the waist hole 21 to adapt to material plate parts of different widths and sizes. Second, the material support arm 2 can rotate into the storage slot 12 to maintain a vertical state. That is, the material support arm 2 reduces the overall space occupied by vertical storage. In the vertical state, it can also be further vertically contracted by sliding the waist hole 21 to reduce space occupation, which greatly improves the utilization rate of workshop space.

[0054] Second Embodiment

[0055] The difference between this embodiment and the first embodiment is that the pin 3 is configured as a T-shaped pin; the free end of the T-shaped pin is threaded, the T-shaped pin passes through the sliding waist hole 21 and the base 1, and the free end of the T-shaped pin is connected by a lock nut thread.

[0056] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
