[0036] like Figures 1-4 As shown, a combined anvil capable of quickly replacing hammers on a perforated roller includes a flat anvil 1 connected to a forging machine, a hammer 2 installed under the flat anvil 1, and two hooks 3 connecting the flat anvil 1 and the hammer 2 together; the hooks 3 have an I-shaped structure; both ends of the flat anvil 1 and the hammer 2 are provided with slots for the hooks 3 to be engaged; the two hooks 3 are respectively engaged in the slots at both ends of the flat anvil 1 and the hammer 2; when the flat anvil 1 and the hammer 2 are connected, they are first positioned by a positioning device, and then connected by the two hooks 3.
[0037] Furthermore, such as Figures 1-4 , Figure 7 As shown, the hammer head 2 has a structure that is wider at the top and narrower at the bottom; the two ends of the upper part of the hammer head 2 are aligned with the two ends of the flat anvil 1.
[0038] Furthermore, such as Figures 1-4 , Figure 6 , Figure 9As shown, the slot includes a horizontal groove 1-1 at both ends of the flat anvil 1, a first vertical groove 1-2 at the lower end of the groove 1-1, and a second vertical groove 2-1 at both ends of the hammer head 2; the first vertical groove 1-2 and the second vertical groove 2-1 are both perpendicular to the groove 1-1 and are on a straight line.
