Description
Technical Field
[0001] The utility model relates to the technical field of metal bending processing, in particular to a metal part bending and forming device. Background Art
[0002] The metal bending forming device is a plastic product that can bend metal materials into the required shape. Metal bending is generally performed by bending the metal material through the pressure of the mold. The device structure and processing process are relatively simple. Compared with stamping, it is easier to control the shape and size of the plate and is suitable for small parts.
[0003] There are two types of devices for bending and forming metal parts: manual and automatic. The existing manually operated bending and forming devices have a simple structure. In order to facilitate the rapid execution of the bending process, in addition to the parts for bending, there is no structure outside the device to limit and fix the processed metal parts. At the same time, in order not to damage the structure of the metal parts, the surfaces of the bending parts are generally set to be circular, which causes the metal parts to be easily tilted when placed in the mold for bending processing, affecting the processing accuracy and being very inconvenient. Utility Model Content
[0004] Based on the above description, the present invention provides a metal part bending and forming device to solve the problem that the existing manual metal part bending and forming device has poor positioning effect and easily causes the metal part to tilt and bend and deviate during processing.
[0005] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: A metal bending and forming device comprises a base, a positioning mold rod is provided on the surface of the base, a movable rod is rotatably connected to the outer side of the positioning mold rod, a threaded rod for bending the metal part along a rotation trajectory is provided on the outer side of the movable rod, a positioning hole is provided on the surface of the movable rod located on the outer side of the threaded rod, a limiting kit for limiting the position of the metal part is installed on the outer side of the threaded rod, the limiting kit passes through the positioning hole and is adjusted to and fro by rotating with the thread of the threaded rod.
[0006] On the basis of the above technical solution, the present invention can also be improved as follows.
[0007] Furthermore, the surface of the positioning mold rod is cylindrical and concave in shape, and both ends of the positioning mold rod are installed in the center of the base surface.
[0008] Furthermore, the movable rod includes a handle, an axial hole and a bearing. The axial hole is opened in the center of one end of the handle surface. The handle is installed on the outside of the positioning mold rod through the axial hole. The bearing is installed between the inner side of the axial hole and one end of the outer side of the positioning mold rod.
[0009] Furthermore, the threaded rod is installed in the center of the handle surface, the positioning hole is arc-shaped, the positioning hole is opened on the surface of the handle and is located on the outside of the threaded rod, the center of the positioning hole coincides with the center of the threaded rod, and the positioning holes are symmetrically distributed with the center of the threaded rod as the origin.
[0010] Furthermore, the limiting kit includes a baffle, a threaded hole and a sleeve plate. The baffle is circular, the threaded hole is opened in the center of the baffle surface, the baffle is installed on the outside of the threaded rod through the threaded hole, and the outside of the baffle is attached to the outside of the positioning mold rod close to one end of the handle.
[0011] Furthermore, both ends of the sleeve are arc-shaped, and the size is adapted to the size of the positioning hole. The sleeve is rotatably connected to the side of the baffle close to the handle and is located on the outside of the threaded hole. The center of the sleeve coincides with the center of the threaded hole. The sleeve is symmetrically distributed with the center of the baffle as the origin and passes through the positioning hole. The inner side of the sleeve fits with the surface of the threaded rod.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0013] The utility model uses a positioning hole opened on the outside of the handle to cooperate with a limit kit threadedly connected to the outside of the threaded rod. The baffle is vertically adjusted to the distance between it and the handle on the outside of the threaded rod in a threaded connection, and the handle positions metal parts of different sizes during bending processing. During the movement of the baffle, the sleeve plate rotatably connected on the outside can move vertically along the outside of the threaded rod under the restriction of the positioning hole, and wrap around the outside of the threaded rod to bend the metal part instead of the threaded rod. The smooth surface of the sleeve plate avoids damage to the surface of the metal part during the bending process. Under the action of the baffle on the positioning processing of the metal part, the phenomenon of tilting and deformation of the metal part during the bending processing is effectively prevented, the stability of the bending forming device during the bending processing of the metal part is increased, and the quality of the finished product of the metal part processing is guaranteed.

[0019] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.
[0021] See also Figure 1-3 The utility model provides a metal bending and forming device, including a base 1, a positioning mold rod 2 is provided on the surface of the base 1, and a movable rod 3 is rotatably connected to the outer side of the positioning mold rod 2. A threaded rod 4 for bending the metal part along a rotation trajectory is provided on the outer side of the movable rod 3, and a positioning hole 5 is provided on the surface of the movable rod 3 and is located on the outer side of the threaded rod 4. A limiting kit 6 for limiting the position of the metal part is installed on the outer side of the threaded rod 4. The limiting kit 6 passes through the positioning hole 5 and is adjusted to and fro by rotating with the thread of the threaded rod 4.
[0022] See also Figure 1 The surface of the positioning mold rod 2 is cylindrical and concave in shape. The two ends of the positioning mold rod 2 are installed in the center of the surface of the base 1. Under the concave shape of the positioning mold rod 2, when the metal parts are bent, they need to pass through the inner side of the positioning mold rod 2 and cooperate with the threaded rod 4 for processing. The positioning mold rod 2 can cooperate with the limiting kit 6 to limit the entire bending metal parts to prevent the metal parts from falling off during processing.
[0023] See also Figure 2The movable rod 3 includes a handle 31, an axial hole 32 and a bearing 33. The axial hole 32 is opened in the center of one end of the surface of the handle 31. The handle 31 is mounted on the outside of the positioning mold rod 2 through the axial hole 32. The bearing 33 is mounted between the inner side of the axial hole 32 and one end of the outside of the positioning mold rod 2. The handle 31 can rotate on the outside of the positioning mold rod 2 through the bearing 33. When the metal part passes through the positioning mold rod 2 and between the positioning mold rod 2 and the threaded rod 4 in turn, the staff can drive the threaded rod 4 to move by rotating the handle 31, so that the threaded rod 4 rotates at different angles on the outside of the positioning mold rod 2 to perform different degrees of bending processing on the metal part. The bending angle of the metal part is controlled by the actual rotation angle of the handle 31 operated by the staff.
[0024] See also Figure 3 The threaded rod 4 is installed in the center of the surface of the handle 31. The positioning hole 5 is arc-shaped. The positioning hole 5 is opened on the surface of the handle 31 and is located on the outside of the threaded rod 4. The center of the positioning hole 5 coincides with the center of the threaded rod 4. The positioning holes 5 are symmetrically distributed with the center of the threaded rod 4 as the origin. There are two positioning holes 5, and the arc paths belong to the same ring. The opening of the positioning holes 5 provides a path for the vertical movement of the sleeve 63 without affecting the structural strength of the threaded rod 4.
[0025] See also Figure 3 The limiting kit 6 includes a baffle 61, a threaded hole 62 and a sleeve plate 63. The baffle 61 is circular, and the threaded hole 62 is opened in the center of the surface of the baffle 61. The baffle 61 is installed on the outside of the threaded rod 4 through the threaded hole 62. The outside of the baffle 61 fits the end of the positioning mold rod 2 close to the outside of the handle 31. The baffle 61 can be rotated vertically on the outside of the threaded rod 4 by thread rotation to adjust the distance between it and the handle 31 so that the baffle 61 can cooperate with the handle 31 to position metal parts of different sizes. The center of rotation of the handle 31 is one end of the positioning mold rod 2. Since the baffle 61 is located at the center of the handle 31, when the handle 31 rotates, the baffle 61 will fit the end of the positioning mold rod 2 that is the center of the handle 31 and move, and will not conflict with the positioning mold rod 2.
[0026] See also Figure 2The two ends of the sleeve 63 are arc-shaped, and the size is adapted to the size of the positioning hole 5. The sleeve 63 is rotatably connected to the side of the baffle 61 close to the handle 31 and is located on the outside of the threaded hole 62. The center of the sleeve 63 coincides with the center of the threaded hole 62. The sleeve 63 is symmetrically distributed with the center of the baffle 61 as the origin and passes through the positioning hole 5. The inner side of the sleeve 63 fits the surface of the threaded rod 4. When the baffle 61 is rotated to adjust the distance between it and the handle 31, the sleeve 63 will move with the baffle 61. Since the sleeve 63 is inserted into the positioning hole 5 and is rotatably connected to the baffle 61, during the rotation adjustment process of the baffle 61, the sleeve 63 will remain stationary on the outside of the baffle 61 and move vertically along the positioning hole 5 to keep wrapping the threaded rod 4 and replace the threaded rod 4 to bend the metal part to avoid damage to the surface of the metal part caused by the thread.
[0027] When it is necessary to process the metal part, first pass the metal part through the inner side of the positioning mold rod 2, and then extend it to between the outer side of the positioning mold rod 2 and the threaded rod 4, and then rotate the baffle 61 on the outside of the threaded rod 4 so that the baffle 61 moves toward the handle 31 on the outside of the threaded rod 4 to clamp the metal part. During the movement of the baffle 61, the sleeve 63 moves along the positioning hole 5 and wraps around the outside of the threaded rod 4 until the baffle 61 completes the clamping of the metal part. Then the staff rotates the handle 31 and bends the metal part through the sleeve 63 wrapped around the outside of the threaded rod 4. The metal part is bent at one end of the positioning mold rod 2 of the rotating axis of the handle 31. After the processing is completed, rotate the baffle 61 again so that the baffle 61 moves on the outside of the threaded rod 4 away from the handle 31, cancels the clamping of the metal part, and then takes out the bent metal part.
