Description

Technical Field

[0001] This utility model relates to the field of shaping tooling technology, specifically to a shaping tooling for flattening the cutting edge. Background Technology

[0002] Workpiece shaping is a common process used in the heat treatment of metal products. Generally, shaping fixtures are used to apply pressure to the workpiece to achieve the purpose. Commonly used shaping fixtures directly fix the workpiece and apply pressure to shape it. However, the lower pressure component is easily affected by rotation and movement during the pressure process, which causes the position of the pressure surface and the workpiece to change, affecting the shaping effect. In addition, the workpiece cutting edge is prone to deformation beyond tolerance, resulting in uneven cutting edges and poor processing quality. Utility Model Content

[0003] The purpose of this utility model is to provide a forming fixture for leveling the cutting edge, which solves the problems of the forming fixture easily moving with the workpiece pressing surface, affecting the forming quality, and the workpiece cutting edge having out-of-tolerance and unevenness.

[0004] Technical Solution: This utility model provides a shaping fixture for flattening the cutting edge, comprising: a base, a support, a pressing component, and a pressure-bearing surface; the support is U-shaped, with several sets evenly spaced on the base, and the support has two pressing holes; the pressing component includes a first pressing member and a second pressing member, which pass through the pressing holes on the support, and both the first and second pressing members are pressure rod structures, with a pressure sleeve below the pressure rod of the first pressing member, and a spherical pressure head below the pressure sleeve; the pressure-bearing surface is located below the first pressing member and is used to press the cutting edge of the workpiece, the pressure-bearing surface is L-shaped, forming a triangular cross-section with the pressed workpiece surface, wherein the small acute angle of the triangle is equal to the slope of the workpiece's inclined surface.

[0005] Furthermore, in the aforementioned shaping fixture for flattening the cutting edge, the base is provided with a first fixing hole, and the bracket is provided with a second fixing hole corresponding to the first fixing hole.

[0006] Furthermore, in the aforementioned shaping fixture for flattening the cutting edge, bolts are inserted into the first and second fixing holes to fix the base and bracket with nuts.

[0007] Furthermore, in the aforementioned shaping fixture for leveling the cutting edge, the length of the first pressing member is greater than that of the second pressing member. The first pressing member is used to press down on the bearing surface, and the second pressing member is used to hold the workpiece in place.

[0008] Furthermore, in the aforementioned shaping fixture for leveling the cutting edge, there are two parallel feet on the top of the base for supporting the cutting edge of the workpiece.

[0009] Furthermore, in the aforementioned shaping fixture for flattening the cutting edge, the outer side of the pressure-bearing surface has a chamfer design.

[0010] Furthermore, in the aforementioned shaping fixture for leveling the cutting edge, the spherical pressure head includes a conversion connector and a steel ball. The conversion connector is disposed within the pressure sleeve, and the steel ball has a mounting hole in the middle for connecting the conversion connector.

[0011] Furthermore, in the aforementioned shaping fixture for leveling the cutting edge, the conversion connector has a cylindrical structure with a diameter smaller than that of the first pressing component.

[0012] Furthermore, in the aforementioned shaping fixture for flattening the cutting edge, the inner through hole of the pressure sleeve adopts a design that is wider at the top and narrower at the bottom. The diameter of the upper channel matches the diameter of the first pressure piece, and the diameter of the lower channel matches the diameter of the conversion connector. A sloping transition structure is provided between the upper and lower channels.

[0013] Furthermore, in the aforementioned shaping fixture for flattening the cutting edge, the bottom surface inside the steel ball mounting hole has a conical structure.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects: The cutting edge leveling shaping fixture described in this utility model has a simple structure, is easy to use, avoids workpiece shaping deviations, and improves processing quality. The pressure head of the fixture adopts a steel ball structure, which rotates downward to apply pressure. Since the steel ball is in point contact with the pressure surface, it can rotate relative to the workpiece, releasing torque. There is only downward pressure, which will not cause the pressure surface to move under force, ensuring that the relative position between the pressure surface and the workpiece remains unchanged. The cross-section of the pressure surface is triangular, in which the small acute angle is equal to the slope of the workpiece's inclined surface, so as to ensure that the steel ball pressure direction is perpendicular. The spherical pressure head is not easily damaged, extending the service life of the fixture. Moreover, the effective force is large when pressing down, which effectively improves the workpiece cutting edge leveling effect. The pads of the base can cause the workpiece cutting edge to have a certain excessive deformation, and rebound after unloading, achieving the purpose of cutting edge shaping.

Detailed Implementation

[0021] Example 1

[0022] like Figure 1 , 4 A shaping fixture for leveling cutting edges is shown, comprising: a base 1, a support 2, a pressing component 3, and a pressure surface 4; the support 2 is U-shaped, with several sets evenly spaced on the base 1, and has two pressing holes; the pressing component 3 includes a first pressing member 31 and a second pressing member 32, which pass through the pressing holes on the support 2. Both the first pressing member 31 and the second pressing member 32 are pressure rod structures. A pressure sleeve 311 is provided below the pressure rod of the first pressing member 31, and a spherical pressure... Head 312; The pressure-bearing surface 4 is located below the first pressure member 31 and is used to press down the workpiece cutting edge. The pressure-bearing surface 4 has an L-shaped structure and forms a triangular cross section with the pressed workpiece surface. The small acute angle of the triangle is equal to the slope of the workpiece inclined surface to ensure that the pressure direction of the spherical pressure head 312 is perpendicular, the spherical pressure head 312 is not easily damaged, and the service life of the tooling is extended. Moreover, the two acute angles of the spherical pressure head 312 and the pressure-bearing surface 4 form a lever, so that the ratio of the power arm to the resistance arm is maximized, the effective force is large when pressing down, the workpiece cutting edge leveling effect is effectively improved, and the force transmission is more uniform.

[0023] like Figure 2 The illustrated shaping fixture for edge leveling includes a spherical pressure head 312 comprising a conversion connector 3121 and a steel ball 3122. The conversion connector 3121 is disposed within a pressure sleeve 311, and the steel ball 3122 has a mounting hole in the center for connecting to the conversion connector 3121. When downward rotation is applied with pressure, the steel ball 3122 is in point contact with the pressure-bearing surface 4, allowing for relative rotation and releasing torque. Only downward pressure exists, preventing the pressure-bearing surface 4 from moving under force, thus ensuring that the relative position of the pressure-bearing surface 4 and the workpiece remains unchanged and improving the shaping quality.

[0024] like Figure 5 The tooling shown is a shaping fixture for leveling the cutting edge. The conversion connector 3121 is a cylindrical structure with a diameter smaller than that of the first pressure member 31. The inner through hole of the pressure sleeve 311 adopts a design that is wider at the top and narrower at the bottom. The diameter of the upper channel matches that of the first pressure member 31, and the diameter of the lower channel matches that of the conversion connector 3121. A sloping transition structure is provided between the upper and lower channels. The bottom surface of the mounting hole of the steel ball 3122 is a conical structure, which facilitates installation and disassembly, ensures tightness of connection, and has self-centering properties.

The base 1 and the bracket 2 are fixed by inserting bolts into the first fixing hole 11 and the second fixing hole 21 and cooperating with nuts 22.

[0027] In this embodiment, the base 1 has two parallel feet 12 above it, which are used to support the cutting edge of the workpiece. The feet 12 of the base 1 can cause the cutting edge of the workpiece to undergo a certain excessive deformation, and spring back after unloading, thereby achieving the purpose of cutting edge shaping.

[0028] like Figure 1 The tooling shown is a shaping fixture for flattening the cutting edge. The first pressing member 31 is longer than the second pressing member 32. The first pressing member 31 is used to press down on the bearing surface 4, and the second pressing member 32 is used to hold the workpiece in place.
