Description

Technical Field

[0001] This utility model relates to the technical field of heavy-duty hydraulic press die holders, and in particular to a die holder for a heavy-duty hydraulic press that prevents displacement. Background Technology

[0002] Heavy-duty hydraulic presses are critical equipment widely used in numerous fields such as machinery manufacturing, automotive industry, aerospace, and shipbuilding. They transmit energy through liquid pressure, generating enormous pressure for forming processes such as forging, stamping, and stretching of metal materials. In these fields, heavy-duty hydraulic presses play a vital role in manufacturing large, high-precision parts, ensuring efficient and high-quality production. The die holder is one of the key components of a heavy-duty hydraulic press. It is primarily used to fix and support the die, providing a stable mounting base for the mold.

[0003] Existing die holders for heavy-duty hydraulic presses make it inconvenient to install the die to prevent offset during use. This results in uneven stress on the die when the heavy-duty hydraulic press applies enormous pressure for stamping operations. This uneven stress not only leads to deviations in the dimensional accuracy of the stamped parts, failing to meet design requirements and seriously affecting product quality, but also, under prolonged offset stress, the die is prone to wear, deformation, and even cracking due to localized stress concentration, significantly shortening the die's service life. Utility Model Content

[0004] The purpose of this invention is to provide a die holder for heavy-duty hydraulic presses that prevents offset, thereby solving the problem that existing die holders for heavy-duty hydraulic presses are inconvenient for anti-offset positioning and installation of the die.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a die holder for a heavy-duty hydraulic press with anti-deviation function, comprising a die holder body;

[0006] A positioning mechanism is installed inside the main body of the die holder;

[0007] The positioning mechanism includes an installation groove inside the die holder body, a positioning groove on the inner side wall of the installation groove, a die being installed inside the installation groove, a positioning block being fixedly connected to the outer wall of the die, a positioning hole being provided inside the die, and the positioning mechanism also includes a threaded groove inside the die holder body, with a bolt being movably connected inside the threaded groove.

[0008] Preferably, the die holder body is engaged with the die through an installation groove, and the die holder body is engaged with a positioning block through a positioning groove, which facilitates the engagement and installation of the die holder body and the die.

[0009] Preferably, the positioning blocks are symmetrically arranged around the central axis of the concave mold, and the positioning blocks are adapted to the positioning grooves to prevent the concave mold from shifting during installation.

[0010] Preferably, the die holder body is threadedly connected to the bolt via a threaded groove, and the bolt is engaged with the die via a positioning hole, allowing one end of the bolt to be inserted into the positioning hole for positioning.

[0011] Preferably, a lifting mechanism is installed on the outer wall of the bolt. The lifting mechanism includes a relief groove formed inside the bolt, a retaining ring installed inside the relief groove, a receiving plate fixedly connected to the outer wall of the retaining ring, a first rack fixedly connected to the outer wall of the receiving plate, a gear movably connected to the outer wall of the first rack, a rotating rod fixedly connected inside the gear, a second rack movably connected to the outer wall of the gear, and a top block fixedly connected to the top of the second rack.

[0012] Preferably, the bolt forms a rotating structure with a relief groove and a retaining ring, and the receiving plate and the die holder body form a sliding structure, which allows the receiving plate to slide along the die holder body.

[0013] Preferably, the first rack is meshed with a gear, the gear forms a rotating structure with the die holder body through a rotating rod, the gear is meshed with a second rack, and the top block forms a sliding structure with the die holder body, which allows the top block to be lifted and pushed out along the die holder body.

[0014] The present invention provides a heavy-duty hydraulic press die holder with anti-deviation feature, the advantages of which are:

[0015] By using the die holder body and positioning mechanism, the die is moved to fit into the mounting slot. The locking action of the positioning block and the positioning slot prevents the die from shifting during installation.

[0016] Furthermore, rotating the bolt allows one end of the bolt to be inserted into the positioning hole for limiting, which facilitates the stable installation of the die holder body and the die, and prevents uneven stress on the die due to improper installation.

[0017] By using the positioning and lifting mechanisms, the rotating bolts drive the retaining ring to move outward, causing the first rack fixedly connected to the outer wall of the receiving plate to move. This allows the gear to rotate and drive the second rack to move upward, causing the top block to push out the die, thus facilitating the disassembly and replacement of the die.

[0018] Furthermore, the interaction between the clearance groove and the retaining ring prevents the retaining ring from rotating as the bolt rotates.

[0019] Furthermore, since the ejector block has a certain clearance distance from the bottom of the die when the die is in the limiting state, it can slide within the clearance distance when the bolt is moved out of the positioning hole, thus avoiding motion interference and further improving the stability of die disassembly and replacement.
