Description

Technical Field

[0001] This utility model relates to the field of stamping equipment, specifically a multi-purpose automatic forming fixture for stamped parts. Background Technology

[0002] During the stamping process, due to factors such as residual stress inside the material, die wear, or fluctuations in process parameters, workpieces are prone to defects such as warping, burrs, and springback deformation. Therefore, shaping and straightening stamped parts that do not meet shape requirements is an indispensable and crucial subsequent process.

[0003] The shaping process mainly involves applying precise secondary pressure to correct specific parts of the workpiece, thereby eliminating deformation and restoring it to the geometric shape and dimensional tolerances required by the design.

[0004] Existing forming fixtures are mostly designed for specific workpieces. Currently, a type of Z-shaped metal bracket needs to be formed during the stamping process, and its upper end is flattened by positive pressure. Existing metal brackets come in various specifications, and the bending lengths of the upper and lower ends of metal brackets of different specifications are different. Therefore, a multi-purpose automatic forming fixture for stamping parts is needed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 A multi-purpose automatic forming fixture for stamping parts includes a machine base 1 and a gantry frame 2. A support base 3 is fixedly connected to the machine base 1. A forming base 4 and a convex rail 5 are fixedly connected to the support base 3. A positioning seat 6 is slidably connected to the convex rail 5. A U-shaped groove 601 is provided in the middle of the positioning seat 6. Arc-shaped limiting strips 602 are provided on both sides of the U-shaped groove 601 on the positioning seat 6. Positioning posts 603 are fixedly connected on both sides of the U-shaped groove 601 on the positioning seat 6. A limiting cylinder 7 is fixedly connected inside the forming base 4. Multiple limiting rods 701 are fixedly connected to the slide of the limiting cylinder 7. The upper diameter of the limiting rod 701 is larger than the lower diameter. The limiting rod 701 is located in the U-shaped groove 601. A forming cylinder 8 is fixedly connected to the gantry frame 2. A seat plate 801 is fixedly connected to the piston rod of the forming cylinder 8. A forming component 9 is provided at the lower part of the seat plate 801.

[0023] The positioning seat 6 has a groove, which can slide along the convex rail 5. The positioning seat 6 can be slid along the convex rail 5 to adjust its position according to the processing requirements.

[0024] The arc-shaped limiting bar 602 is C-shaped. When the limiting cylinder 7 drives the limiting rod 701 to descend, it can descend to the curved section of the arc-shaped limiting bar 602 to limit the positioning seat 6. The lower part of the upper end of the limiting rod 701 is a conical surface. During the descent of the limiting rod 701, the conical surface can automatically correct the positioning seat 6.

[0025] A clearance groove is provided on the shaping base 4. When the metal bracket is placed, the clearance groove 4 can position and limit it. When the metal bracket is shaped, the clearance groove makes way for the downward pressure of the shaping component 9.

[0026] The shaping assembly 9 includes a main rod 901, a sliding sleeve 902, and a shaping pressure plate 903. The installation position of the sliding sleeve 902 can be adjusted up and down along the main rod 901. The shaping pressure plate 903 is integrated with the sliding sleeve 902. After the position adjustment is completed, the sliding sleeve 902 is fixed to the locking hole by a screw. The main rod 901 is provided with a flat groove, and the sliding sleeve 902 is slidably connected to the flat groove. A reinforcing rib 904 is provided between the shaping pressure plate 903 and the sliding sleeve 902 to prevent deformation of the shaping pressure plate 903.

[0027] The working principle of this utility model is as follows: The metal bracket can be regarded as a Z-shape, with the middle section of the metal bracket being vertical and the upper and lower ends of the metal bracket being horizontally bent, and a through hole being opened at the lower end of the metal bracket. Before use, according to the length of the vertical section of the metal bracket, a shaping base 4 of appropriate height is selected and installed on the support base 3 (the support base 3 has a through hole for installing the shaping base 4, and the shaping base 5 is installed on the support base 3 by fasteners). Then, according to the length of the horizontal section of the metal bracket, the position of the positioning seat 6 is adjusted, the piston rod of the limiting cylinder 7 extends, the limiting rod 701 rises and is misaligned with the arc-shaped limiting strip 602, and then the position of the positioning seat 6 is adjusted by sliding. After the translation is completed, the piston rod of the limiting cylinder 7 returns to its original position, and the limiting rod 701 descends and is locked into the arc-shaped limiting strip 602 to achieve the limiting. Then, the position of the shaping pressure plate 903 is adjusted, and by adjusting the position of the sliding sleeve 902, it is fixed to the locking hole by a screw, thus completing the adjustment.

[0028] When shaping the metal bracket, the through hole at the lower end of the metal bracket is placed on the positioning seat 6 and the shaping base 4 along the positioning post 603 and the relief groove of the limiting rod 701. Then the piston rod of the shaping cylinder 8 extends, the seat plate 801 descends, and the shaping pressure plate 903 presses the bent section at the upper end of the metal bracket onto the shaping base 4 to complete the shaping.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
