Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings 1-4.

As shown in figures 1 and 3, the novel arc anvil of the rapid forging machine comprises a lower arc anvil 1, an upper arc anvil 2, a spring 3, a guide pillar 4 and a U-shaped equal-height block 5. The cross section of the lower arc anvil 1 is integrally T-shaped, the upper part is large, the lower part is small, the lower arc anvil 1 comprises an upper part and a lower part, the upper part is a platform, and a semicircular groove is formed in the center of the platform; the lower part of the lower arc anvil 1 is provided with a guide rail 20, and the guide rail 20 is a dovetail rail; the center of the lower part of the upper arc anvil 2 is also provided with a semicircular groove, the upper arc anvil 2 is arranged at the upper part of the lower arc anvil 1, and the groove of the upper arc anvil 2 is opposite to the groove of the lower arc anvil 1. The bottom of the lower arc anvil 1 is provided with a positioning key 8 on each side of the guide rail 20 for positioning when the lower arc anvil 1 is mounted on a base (not shown).

The upper platform of the lower arc anvil 1 is respectively provided with a lug 22 at two sides of the groove, a preset distance is reserved between the edge of the lug 22 and the edge of the bottom surface of the platform, the two lugs 22 are both provided with a mounting hole, the spring 3 is mounted in the mounting hole of the lug 22, the length of the spring 3 is greater than the depth of the mounting hole, and therefore the top end of the spring 3 is exposed out of the top of the mounting hole; the lower part of the upper arc anvil 2 is respectively provided with a channel 21 at two sides of the groove, the center of the channel 21 is provided with a guide post 4, and the guide post 4 is fixed at the top of the upper arc anvil 2 by a bolt; the two lugs 22 of the lower circular arc anvil 1 are respectively mounted in the two channels 21 of the upper circular arc anvil 2, and the guide post 4 is inserted in the central hole of the spring 3. Two opposite outer side walls of the lower arc anvil 1 and the upper arc anvil 2 are respectively provided with 2 hoisting holes 7 for hoisting the lower arc anvil 1 and the upper arc anvil 2.

The U-shaped block 5 is inserted into the gap 25 between the upper circular anvil 2 and the lower circular anvil 1, and as shown in fig. 3, nuts 11 are welded to the ends of the two side arms of the U-shaped block 5 for installing fastening screws 12 and positioning and fastening the U-shaped block 5.

When the size of the gap 25 between the upper arc anvil 2 and the lower arc anvil 1 is adjusted, a plurality of U-shaped equal-height blocks 5 are required to be assembled to meet the size requirement; as shown in fig. 4, three U-shaped equal-height blocks 5 are stacked together, and the contact surfaces between the equal-height blocks are welded and fixed, so that the three equal-height blocks 5 are integrated into an integral equal-height block, and a nut 11 is welded at the end of the integral equal-height block.

When the novel arc anvil of the rapid forging machine is used, the guide post 4 is installed in a spring hole of the spring 3 and can move up and down in the spring hole of the spring 3, the spring 3 can freely stretch and retract in a central hole of a lug 22 of the lower arc anvil, when the upper surface of the upper arc anvil 2 applies pressure, the upper arc anvil 2 moves downwards until reaching the contour block 5, in the process, the spring 3 is compressed in the central hole of the lug 22, and the guide post 4 moves downwards along the spring hole; when pressure is removed, the spring returns to the original length by means of the elasticity of the spring, the guide pillar moves upwards along the spring, and the upper arc anvil returns to the original height. As described above, the equal-height block or the integral equal-height block is inserted into the gap 25 between the upper arc anvil 2 and the lower arc anvil 1, and the height of the equal-height block is properly increased according to the requirement of the product diameter and the height between the upper arc anvil 2 and the lower arc anvil 1, for example, the height between the semicircular grooves of the upper and lower arc anvils is 500mm, the product diameter is 450mm, and the equal-height block 5 with the thickness of 50mm needs to be installed in the gap 25, so that each time the pressure is applied to the upper plane of the upper arc anvil 2 to compress the spring until the height of the gap 25 is 0, the height between the semicircular grooves of the upper and lower arc anvils is 450mm, that is, the product size, and when the pressure on the upper plane of the upper arc anvil is removed, the spring returns the height between the semicircular grooves of the upper and lower arc anvils to the original 500mm by means of the self elasticity. Without the contour block, it is difficult to precisely control the product size at 450mm per depression.

The utility model discloses, through setting up the high piece, can restrict the activity space of spring, when the production uses, can fix forging stock finished product size at a certain numerical value, realize the homogeneity of forging stock through root size, improve the surface dimension precision of forging stock product, reach customer's tolerance requirement, improve forging stock yield, and then reduction in production cost.
