Description

Technical Field

[0001] This utility model relates to the field of forging technology, and in particular to a wear-resistant arc anvil device for high-speed forging machines. Background Technology

[0002] High-speed forging machines, also known as high-speed fully hydraulic forging machines, are characterized by high frequency, high energy, and stable torque. They are suitable for large-scale batch production. High-speed forging machines have relatively low requirements for raw materials and can effectively forge various metal materials. In addition, they can reduce material waste and labor costs during the forging process, so they are widely used in large-scale industrial production.

[0003] The patent application "214557093U" describes a "novel circular arc anvil for a high-speed forging machine," comprising a lower circular arc anvil, an upper circular arc anvil, and a leveling block. The lower circular arc anvil consists of two parts, larger at the top and smaller at the bottom. The upper part of the lower circular arc anvil is a platform with a semi-circular groove in its center, and the lower part is a guide rail. The lower part of the upper circular arc anvil also has a semi-circular groove in its center. The upper circular arc anvil is installed on top of the lower circular arc anvil, with its groove opposite to that of the lower circular arc anvil. The leveling block is installed in the gap between the upper and lower circular arc anvils. This invention can improve the surface dimensional accuracy of forged products, increase the yield of forged materials, and thus reduce production costs.

[0004] In the current high-speed forging machine, the upper anvil needs to move up and down continuously during the forging process. The guide columns on the upper and lower anvils rub against each other for a long time, which will cause wear. This will result in the upper and lower anvils not fitting tightly, which will cause shaking. This will cause the upper and lower arc anvils to be out of concentricity, resulting in the bending and deformation of the forged bar. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant arc anvil device for high-speed forging machines, which solves the problem that the upper anvil needs to move up and down continuously, and the guide columns on the upper and lower anvils rub against each other for a long time, which causes wear, resulting in poor fit between the upper and lower anvils and wobbling.

[0010] According to the wear-resistant arc anvil device for the high-speed forging machine, a contact plate is slidably connected inside the guide groove, and a third spring is fixedly connected between the lower surface of the contact plate and the bottom of the guide groove. The pressure is buffered by the elastic force of the third spring, thereby improving the service life of the machine.

[0011] According to the wear-resistant arc anvil device for high-speed forging machine, a positioning groove is provided on the side of the mounting port away from the mounting groove. A positioning block is fixedly connected to the side of the first inclined block away from the locking port. The lower end of the positioning block is inserted into the positioning groove.

[0015] According to the wear-resistant arc anvil device for the high-speed forging machine, the lower end of the guide post contacts the upper surface of the contact plate, which facilitates the disassembly of the guide post.

[0016] The above-mentioned solution has the following beneficial effects:

[0017] 1. By setting up a lower anvil, an upper anvil, and protective components, the first inclined block can be inserted into the installation port. The first inclined block can squeeze the locking ball to move it. The locking ball can drive the fixing ring to move, which in turn can deform the first spring. The first spring reset can drive the locking ball to reset, so that it is locked into the locking port. This can automatically install and fix the copper plate. Using the copper plate can reduce the wear of the upper anvil and avoid the upper and lower anvils from not fitting tightly, thus preventing the rod from deforming. By pushing the push plate, the third inclined block can drive the second inclined block to move, which can then drive the locking ball to disengage from the locking port, allowing for quick removal of the copper plate. This achieves the effect of quick removal and installation of the copper plate, greatly improving the practicality and efficiency of the device.

[0018] 2. By setting a limiting component, the guide post can slide in the guide groove, which can guide the vertical movement of the upper anvil and improve the stability of the upper anvil movement. The screw at the top of the guide post can be screwed into the threaded groove, which can quickly install and replace the worn guide post, thereby further improving its practicality.
