Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts production, and specifically relates to a novel inclined wedge supporting mechanism. Background Art

[0002] Here we mainly talk about a new type of supporting mechanism used in cold stamping blanking dies in the automotive industry. With the development of the automotive industry, the demand for stamping parts has greatly increased. In order to improve the utilization rate of materials and reduce project development costs, the blanking die process came into being. Due to the large size of some parts, the sheet metal sags due to the influence of gravity during the production process, resulting in unqualified blanking products. Although the conventional supporting mechanism can solve the influence of gravity, it also causes the abnormality that the product cannot slide normally. Therefore, the present invention better solves the dual problem of both supporting and sliding materials. Utility Model Content

[0003] In order to solve the above problems, the technical solution of the utility model is as follows: a new type of inclined wedge supporting mechanism, the base is a cavity structure, a horizontal spring mechanism is provided at the bottom of the cavity, one end of the spring mechanism is fixed to the side of the cavity, a nitrogen spring piston rod is provided at the other end of the spring mechanism, an inclined wedge mechanism is provided above the spring mechanism, the inclined wedge mechanism includes an inclined wedge slider below and an inclined wedge driving block above, a side baffle is provided at the bottom of the inclined wedge slider, the side baffle is in contact with the nitrogen spring piston rod, and a supporting rack assembly is provided on the inclined wedge slider.

[0004] In the above-mentioned novel inclined wedge supporting mechanism, limiting pressure plates are arranged on both sides of the cavity on the upper surface of the base, and bosses are arranged on the sides of the inclined wedge slider, and the inclined wedge slider slides in the horizontal direction under the limiting pressure plates.

[0005] In the above-mentioned novel inclined wedge supporting mechanism, the supporting frame assembly is fixed above the inclined wedge sliding block, and the supporting plate on the supporting frame assembly is arranged perpendicular to the movement direction of the spring mechanism.

[0006] The wedge mechanism of the utility model can be designed with customized external dimensions according to the mold space, and the support frame assembly can be designed specifically according to the size of the parts and the required support position.

[0007] The new inclined wedge support mechanism has two states: contact and separation with the sheet metal. This device occupies a small space, which not only solves the problem of installing the support device in a small space, but also realizes the dual functions of the support rack in the mold production process to ensure the stability of the feeding process, and the support rack needs to avoid the sliding trajectory of the parts during the sheet metal sliding process.

[0008] For a blanking die with a large sheet metal size, due to the influence of gravity, the sheet metal is prone to deviating from the original running track and sagging, resulting in defective products or even scrap; during automated production, to ensure the stability of the feeding process, this kind of sheet supporting mechanism can be considered.

[0009] When the blanked sheet metal parts or large-sized waste cut during the working process of the blanking die slide out of the die, the movement track should not be blocked, and sufficient sliding space must be ensured. To achieve this function, this kind of sheet supporting mechanism can be considered.

[0010] Advantages of the present utility model

[0011] During the production process of the blanking die, when the wedge driving block moves with the driving mechanism and the die opens, the wedge sheet supporting mechanism moves forward under the action of the spring mechanism to support the sheet metal, eliminating the influence of the gravity of the sheet metal and ensuring the stability of automated feeding; when the wedge driving block moves downward with the driving mechanism and the die closes to complete blanking and trimming, the wedge slider moves backward under the action of the wedge driving block to ensure that the blanked product slides out of the die cavity normally. This application mechanism better ensures the stability of the production process. Description of the drawings

[0017] Such as Figures 1 - 3As shown in the figure, for the new inclined wedge material supporting mechanism, the base 2 is of a cavity structure. A spring mechanism 3 in the horizontal direction is provided at the bottom of the cavity. One end of the spring mechanism 3 is fixed to the side surface of the cavity, and the other end of the spring mechanism 3 is provided with a nitrogen spring piston rod. An inclined wedge mechanism is provided above the spring mechanism 3. The inclined wedge mechanism includes an inclined wedge slider 5 below and an inclined wedge driving block 6 above. The contact surfaces between the inclined wedge slider 5 and the inclined wedge driving block 6 are 45° inclined surfaces. A side baffle is provided at the bottom of the inclined wedge slider 5. The side baffle contacts the nitrogen spring piston rod. A material supporting frame assembly 1 is provided on the inclined wedge slider 5. The material supporting frame assembly 1 is fixed above the inclined wedge slider 5. The material supporting plate 7 on the material supporting frame assembly 1 is arranged perpendicular to the movement direction of the spring mechanism 3.

[0018] Limit pressing plates 4 are provided on both sides of the cavity on the upper surface of the base 2. The limit pressing plates 4 are connected to the upper surface of the base 2 by bolts. A boss is provided on the side surface of the inclined wedge slider 5. The limit pressing plate 4 can cover the boss of the inclined wedge slider 5. When the inclined wedge slider 5 is stressed, it slides horizontally along the lower part of the limit pressing plate 4.

[0019] The usage process is as follows: The inclined wedge driving block 6 is connected to the driving mechanism above. The driving mechanism applies a downward force. The inclined wedge driving block 6 moves downward. The 45° inclined surface at the bottom of the inclined wedge driving block 6 pushes the 45° inclined surface at the top of the inclined wedge slider 5, causing the inclined wedge slider 5 to slide backward horizontally. Furthermore, the blanking plate of the material supporting frame assembly 1 moves backward, enabling the sheet metal 9 to fall onto the equipment below. When it is necessary to hold the sheet metal, the driving mechanism drives the inclined wedge driving block 6 to move upward. Without external force applied, the spring mechanism 3 returns to its original position, and the inclined wedge slider 5 follows the spring mechanism 3 back to its original position. The blanking plate of the material supporting frame assembly 1 moves forward to catch the sheet metal 9.

[0020] Figure 4 The new inclined wedge material supporting mechanism is applied to the uncoiling and blanking die. When this part is fed, the size of the suspended part of the sheet metal is relatively large (970 mm in length). It is necessary to use the new inclined wedge material supporting mechanism to ensure that the sheet metal does not sag and deform due to gravity. After cutting, the blanking products (the blanking products 1 and 2 shown in the figure) need to slide out of the die. The new inclined wedge material supporting mechanism needs to retract and disengage from the products to ensure the sliding space for the products. The new material supporting mechanism exactly meets the requirements.
