Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to an inclined wedge structure and a stamping die device. Background Art

[0002] The inclined wedge structure is a mechanical element used to adjust or fix the relative position between parts. It is wedge-shaped and is usually used as a fixture, locator or supporting element. In the automotive cover mold, the inclined wedge structure is used to adjust the positioning, fixing or supporting of the cover to ensure the correct operation of the mold. Specifically, the inclined wedge structure includes an upper base, a guide plate, a sliding block and a driving block. The upper base is fixedly mounted on the upper mold of the die mold, the guide plate is fixed to the inclined surface of the upper base, the sliding block is slidably connected to the guide plate, the driving block is mounted on the lower mold of the die mold, and the driving block is provided with a slide rail for sliding with the guide plate. During the downward pressing process of the upper mold, the sliding block can abut against the slide rail. As the upper mold continues to be pressed downward, the sliding block can slide along the slide rail under the action of the guide plate to complete the positioning, fixing or supporting of the cover.

[0003] However, as the number of times the inclined wedge structure works increases, wear will occur between the sliding block and the inclined surface of the upper base, and between the sliding block and the guide plate, resulting in a wear gap between the sliding block and the upper base, and the wear gap gradually increases with the number of times the structure works. In addition, since it is not easy to replace the various parts of the inclined wedge structure individually, they often need to be replaced as a whole, which increases the production cost.

[0040] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0041] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0042] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0043] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0044] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0045] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0046] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0047] See also Figures 1 to 5 In this embodiment, a die device is provided, including a first workpiece (not shown in the figure), a second workpiece (not shown in the figure) and an inclined wedge structure, and the first workpiece can approach the second workpiece. It can be understood that when the first workpiece moves toward the second workpiece, the adjustment cover is positioned, fixed or supported by the inclined wedge structure.

[0048] It should be noted that, in this embodiment, the first workpiece specifically refers to the upper die in the die equipment, and the second workpiece specifically refers to the lower die in the die equipment.

[0049] In this embodiment, a wedge structure is also proposed, which includes an upper base 1, a guide plate 2, a sliding block 3 and a driving block 4. The upper base 1 is arranged on the first workpiece and has an inclined surface 11. The guide plate 2 is arranged on one side of the upper base 1, and the length direction of the guide member 21 of the guide plate 2 is arranged parallel to the inclined surface 11, and one end of the guide member 21 is arranged adjacent to the retaining wall 12. The sliding block 3 is slidably connected to the guide member 21 and fits with the inclined surface 11. The driving block 4 is arranged on the second workpiece, and the driving block 4 includes a slide rail 41. When the first workpiece approaches the second workpiece, the sliding block 3 can abut against the slide rail 41 and slide along the slide rail 41 and the guide member 21 at the same time. However, as the number of times the wedge structure works increases, wear will occur between the sliding block 3 and the inclined surface 11 of the upper base 1, and wear will also occur between the guide member 21 and the guide groove of the sliding block 3, so that a wear gap is generated between the sliding block 3 and the upper base 1, and the wear gap gradually increases with the increase in the number of times the work is done. Furthermore, since the various components of the inclined wedge structure are not convenient to replace individually, they often need to be replaced as a whole, which increases the production cost.

[0050] In order to solve the above technical problems, in this embodiment, the side wall of the upper base 1 is provided with a mounting groove 13, and the side wall of the guide plate 2 is provided with a protrusion 22 adapted to the mounting groove 13, the protrusion 22 is arranged in the mounting groove 13, and the position of the protrusion 22 is adjustable; the mounting groove 13 includes a first bottom wall 131, and a first angle is set between the length direction of the first bottom wall 131 and the length direction of the inclined surface 11, and the opening of the first angle faces the rising end of the inclined surface 11; the protrusion 22 includes a second bottom wall 221 that is in contact with the first bottom wall 131, and a second angle is set between the length direction of the second bottom wall 221 and the length direction of the inclined surface 11, and the opening of the second angle faces the descending end of the inclined surface 11, and the first angle is the same as the second angle.

[0051] It can be understood that when the wear gap between the sliding block 3 and the upper base 1 is too large, by adjusting the position of the protrusion 22 in the mounting groove 13, and since a first angle is set between the length direction of the first bottom wall 131 and the length direction of the inclined surface 11, the position of the protrusion 22 can be adjusted to adjust the spacing between the guide member 21 and the inclined surface 11. Since a second angle is set between the length direction of the second bottom wall 221 and the length direction of the inclined surface 11, the second angle can ensure that the guide plate 2 keeps the guide member 21 in a state parallel to the inclined surface 11 during the movement. Since the sliding block 3 is slidably connected to the guide member 21, the guide plate 2 can drive the sliding block 3 to move while moving to eliminate the wear gap between the sliding block 3 and the upper base 1.

[0052] It should be noted that two guide plates 2 are provided, and the two guide plates 2 are symmetrically arranged about the upper base 1, and a guide groove is correspondingly provided on the sliding block 3, and the guide groove is adapted to the guide member, so that the sliding block 3 is slidably connected to the guide members 21 of the two guide plates 2 at the same time, so as to ensure the stability of the sliding block 3 during the movement process. In addition, during the movement process of the guide member 21, the guide member 21 can keep in contact with the guide groove, so as to eliminate the gap between the guide member 21 and the guide groove caused by wear.

[0053] Furthermore, the inclined wedge structure also includes a wear-resistant plate 5, which is detachably arranged on the inclined surface 11, and the side wall of the wear-resistant plate 5 facing away from the inclined surface 11 is in contact with the sliding block 3. It can be understood that the wear-resistant plate 5 can prevent the sliding block 3 from directly contacting the inclined surface 11, and the sliding block 3 contacts the wear-resistant plate 5 during the sliding process. Since the wear-resistant plate 5 has the wear-resistant property, the service life of the inclined wedge structure can be increased. After the wear-resistant plate 5 is used for a period of time, a wear gap is generated between the wear-resistant plate 5 and the sliding block 3, which can be replaced by another thicker wear-resistant plate 5, thereby reducing the production cost.

[0054] The wear-resistant plate 5 is made of a copper alloy, such as a copper-tin alloy and a copper-zinc alloy, etc., which are not specifically limited here. In addition, the thickness of the wear-resistant plate 5 can be determined according to actual working conditions, which will not be described in detail here.

[0055] In this embodiment, the upper base 1 has a retaining wall 12, which is arranged at the rising end of the inclined surface 11; the sliding block 3 is provided with a mounting hole on the side wall facing the retaining wall 12, and the axis of the mounting hole is consistent with the length direction of the inclined surface 11; the inclined wedge structure also includes a nitrogen spring 6, one end of which is arranged in the mounting hole, and the other end is in contact with the retaining wall 12. It can be understood that during the die punching process, when the upper base 1 approaches the driving block 4, after the sliding block 3 contacts the slide rail 41, the sliding block 3 stops moving downward, and the upper base 1 continues to move downward. Under the action of the inclined surface 11, the sliding block 3 can move toward the retaining wall 12, thereby compressing the nitrogen spring 6. When the die is completed, the upper base 1 moves in a direction away from the driving block 4, and under the action of the nitrogen spring 6, it can return to the initial position of the sliding block 3, so as to facilitate subsequent work. However, as the number of die punching increases, the nitrogen spring 6 will leave a depression on the retaining wall 12, and the depression is likely to affect the consistency of the die punching.

[0056] To this end, in this embodiment, the inclined wedge structure further includes a top block 7, which is detachably arranged on the retaining wall 12, and the other end of the nitrogen spring 6 abuts against the retaining wall 12. This arrangement can avoid direct contact between the nitrogen spring 6 and the retaining wall 12, and when the top block 7 is dented, the top block 7 can be replaced. Compared with replacing the entire inclined wedge structure, replacing the top block 7 can reduce production costs.

[0057] Preferably, the top block 7 is made of a hard material. In some other feasible embodiments, the top block 7 can also be hardened by heat treatment to improve the hardness of the top block 7.

[0058] In order to facilitate the adjustment of the position of the guide plate 2, a positioning hole 23 and a plurality of oblong holes 24 are provided on the guide plate 2, and the length direction of any oblong hole 24 is consistent with the direction of the guide member 21; the inclined wedge structure also includes a plurality of column pins 8, and the column pins 8 are adapted to the positioning holes 23 and the oblong holes 24. It can be understood that when installing the guide plate 2, the column pins 8 are first matched with the positioning holes 23 to complete the positioning of the guide plate 2, and then the column pins 8 are matched with the oblong holes 24 to complete the installation of the guide plate 2. When adjusting the position of the guide plate 2, the matching between the positioning hole 23 and the column pins 8 is released, and then the second bottom wall 221 is slid on the first bottom wall 131. When it moves to the preset position, the positioning hole 23 is reopened on the guide plate 2, and the positioning hole 23 is matched with the column pins 8 for positioning.

[0059] In addition, both ends of the protrusion 22 are provided with round chamfers 222. The provided round chamfers 222 can prevent the protrusion 22 and the mounting groove 13 from getting stuck during the movement of the guide plate 2.

[0060] During the movement of the sliding block 3, a wear gap will also be generated between the sliding block 3 and the slide rail 41, and the wear gap generated here will affect the positioning, fixing or supporting of the cover. For this reason, in this embodiment, the driving block 4 also includes a driving body 42, the driving body 42 is arranged on the second workpiece, and the slide rail 41 is detachably connected to the driving body 42. Compared with replacing the entire driving block 4, replacing the slide rail 41 in this embodiment can further reduce the production cost.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
