Abstract
Description
Technical Field
[0001] The utility model relates to a matching tool in the field of mechanical processing, in particular to a plate bending tool. Background Art
[0002] In the field of mechanical processing, sheet metal bending is a common mechanical processing mode, and corresponding bending tooling is required when bending the sheet metal.
[0003] The existing bending tool includes a tool base with a V-shaped bending groove. When in use, the plate to be bent is placed on the upper side of the bending groove, and the bending knife applies pressure to the plate under the drive of the press head. Under the shaping effect of the bending groove, the bending knife bends the plate into a set angle.
[0004] The problem with the existing technology is that the working conditions when bending the plates are diverse. For example, the thickness of the plates to be bent is different, and the bending angles required for the plates to be bent are different. In the existing technology, a bending tool can often only match the bending angle requirement of a plate of a certain thickness. When facing plates of different thicknesses or different bending angles, the corresponding bending tool needs to be replaced. In order to meet the needs of various thicknesses and various bending angles, the factory needs to prepare many sets of bending tools, which will undoubtedly increase the processing cost of the project. Multiple sets of bending tools will also occupy a large storage space in the factory, increasing the storage cost of the factory. Utility Model Content
[0005] The utility model aims to provide a plate bending tool to solve the technical problem that the existing bending tool can only match one thickness plate and one bending angle requirement and has poor versatility.
[0006] In order to solve the above technical problems, a technical solution of a plate bending tool in the utility model is as follows:
[0007] A sheet bending tool comprises a tool support, on which a left bending bottom mold and a right bending bottom mold with adjustable left and right spacing are arranged, the axes of the left bending bottom mold and the right bending bottom mold are extended in the front-back direction, and the installation angles of the left bending bottom mold and the right bending bottom mold relative to the tool support can be rotated and adjusted around their axes. The sheet bending tool also comprises a fixing structure for fixing the left bending bottom mold and the right bending bottom mold after the installation angles and relative spacing of the left bending bottom mold and the right bending bottom mold are adjusted, at least two left forming inclined surfaces are arranged on the outer periphery of the left bending bottom mold, and at least two right forming inclined surfaces are arranged on the outer periphery of the right bending bottom mold for use with the corresponding left forming inclined surfaces, and each right forming inclined surface is used to form a combined V-shaped bending groove for shaping the sheet with the corresponding left forming inclined surface.
[0008] Furthermore, the slopes of different left-side forming slopes are different, so that each combined V-shaped bending groove is used to match plates with different bending angle requirements.
[0009] Furthermore, the left-side forming inclined surfaces on the left-side bending bottom mold are arranged at intervals or continuously along the circumferential direction; and the right-side forming inclined surfaces on the right-side bending bottom mold are arranged at intervals or continuously along the circumferential direction.
[0010] Furthermore, the outer peripheries of the left bending bottom mold and the right bending bottom mold are respectively provided with one or more independent V-shaped bending grooves, and the groove depth of the independent V-shaped bending groove is smaller than the groove depth of the combined V-shaped bending groove.
[0011] Furthermore, the tooling bracket includes a front bracket plate and a rear bracket plate, the front bracket plate is provided with a front guide groove extending in the left-right direction, the rear bracket plate is provided with a rear guide groove extending in the left-right direction, a left bottom mold shaft is fixed on the left bending bottom mold, and a right bottom mold shaft is fixed on the right bending bottom mold, the front ends of the left bottom mold shaft and the right bottom mold shaft are assembled in the front guide groove, and the rear ends of the left bottom mold shaft and the right bottom mold shaft are assembled in the rear guide groove, and the fixing structure includes a left nut threadedly connected to the front and rear ends of the left bottom mold shaft and a right nut threadedly connected to the front and rear ends of the right bottom mold shaft.
[0012] The beneficial effects of the utility model are as follows: the combined V-shaped bending groove in the utility model is composed of the left-side forming inclined surfaces and the right-side forming inclined surfaces on the left-side bending bottom mold and the right-side bending bottom mold. When facing plates of different thicknesses, we can adapt to the bending of plates of different thicknesses by adjusting the spacing between the left-side bending bottom mold and the right-side bending bottom mold; and when facing different bending angle requirements, we can first loosen the fixed structure, rotate the left-side bending bottom mold and the right-side bending bottom mold, and adjust the installation angle of the left-side bending bottom mold and the right-side bending bottom mold relative to the working bracket, so that other left-side forming inclined surfaces and corresponding right-side forming inclined surfaces are combined into a new combined V-shaped bending groove, thereby matching plates with corresponding bending angle requirements, thereby improving the versatility of the product.

[0020] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0021] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0022] The implementation of a plate bending tool in the utility model is as follows: Figures 1 to 5 As shown: it includes a tooling bracket, the tooling bracket includes a front bracket plate 8 and a rear bracket plate 14 arranged at a front-to-back interval, the front bracket plate 8 and the rear bracket plate 14 are equipped with a left bending bottom mold 4 and a right bending bottom mold 3 with adjustable left and right spacing, the left bending bottom mold and the right bending bottom mold are axial structures with axes extending along the front-to-back direction, and the installation angles of the left bending bottom mold and the right bending bottom mold relative to the tooling bracket can be rotated and adjusted around their axes, and the plate bending tooling also includes a fixing structure for fixing the left bending bottom mold and the right bending bottom mold after the installation angles and relative spacing of the left bending bottom mold and the right bending bottom mold are adjusted.
[0023] In this embodiment, a front guide groove extending in the left-right direction is provided on the front support plate 8, and a rear guide groove 13 extending in the left-right direction is provided on the rear support plate 14. A left bottom mold shaft 9 is fixed on the left bending bottom mold, and a right bottom mold shaft 10 is fixed on the right bending bottom mold. The front ends of the left bottom mold shaft and the right bottom mold shaft extend into the front-to-front guide groove, and the rear ends of the left bottom mold shaft and the right bottom mold shaft extend into the rear guide groove 13. The fixing structure includes a left nut 11 threadedly connected to the front and rear ends of the left bottom mold shaft and a right nut 12 threadedly connected to the front and rear ends of the right bottom mold shaft.
[0024] When the left nut 11 and the right nut 12 are loosened, not only the relative distance between the left bottom mold axis and the right bottom mold axis can be adjusted, but also the installation angle of the left bending bottom mold and the right bending bottom mold can be adjusted. After the installation angle and relative distance of the left bending bottom mold and the right bending bottom mold are adjusted, tightening the left nut 11 and the right nut 12 can achieve the fixation of the left bending bottom mold and the right bending bottom mold. A plurality of left forming inclined surfaces 4 are arranged on the periphery of the left bending bottom mold, and the inclinations of the left forming inclined surfaces are different. The periphery of the right bending bottom mold is arranged on the periphery of the right bending bottom mold with right forming inclined surfaces 5 corresponding to the number of left forming inclined surfaces, and each right forming inclined surface is used to form a combined V-shaped bending groove 6 for shaping the corresponding plate with the corresponding left forming inclined surface.
[0025] In general, the left bending bottom mold and the right bending bottom mold are arranged symmetrically, and the slopes of the different left forming slopes are different, so that each combined V-shaped bending groove is used to match the plates with different bending angle requirements.
[0026] The left-side forming inclined surfaces on the left-side bending bottom die are arranged at intervals (or continuously) along the circumferential direction; and the right-side forming inclined surfaces on the right-side bending bottom die are arranged at intervals (or continuously) along the circumferential direction.
[0027] The outer peripheries of the left bending bottom mold and the right bending bottom mold are respectively provided with one or more independent V-shaped bending grooves 7 , and the groove depth of the independent V-shaped bending groove 7 is smaller than the groove depth of the combined V-shaped bending groove 6 .
[0028] When in use, the bending knife 1 is fixed on the pressure head of the press machine. The bending knife can move up and down under the drive of the pressure head. According to the required bending angle of the plate to be bent, the appropriate left-side forming bevel and right-side forming bevel are selected to cooperate to form a combined V-shaped bending groove. According to the thickness of the plate to be bent, the spacing between the left-side forming bevel and the right-side forming bevel is adjusted, and then the left-side nut and the right-side nut are tightened to fix the left-side bending bottom mold and the right-side bending bottom mold. The plate to be bent is placed on the upper side of the combined V-shaped bending groove, and the bending knife moves downward to apply pressure to the plate to bend the plate. Of course, when the required bending angle of the plate is very small, the left and right positions of the left and right bending bottom molds are adjusted, and the bending and shaping of the plate can also be achieved by relying solely on the independent V-shaped bending grooves on the left and right bending bottom molds.
[0029] In the above description of this specification, unless otherwise clearly specified and limited, the terms "fixed", "installed", "connected" or "connected" should be understood in a broad sense. For example, with regard to the term "connection", it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. Therefore, unless otherwise clearly defined in this specification, those skilled in the art can understand the specific meanings of the above terms in this utility model according to the specific circumstances.
[0030] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "up", "down", "front", "back", "left", "right", "length", "width", "thickness", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "center", "longitudinal", "lateral", "clockwise" or "counterclockwise", etc., which indicate the orientation or position relationship, are based on the orientation or position relationship shown in the drawings of this specification, and are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in a specific orientation.
