Technical Field

The utility model relates to a mechanical forging equipment technical field, more specifically relate to an air hammer's anvil block structure.

Background

Forging is an important processing means in machining and production of mechanical equipment, and the most common forging equipment and an air hammer are mainly used for compressing air through a compression cylinder, sending the air into a working cylinder through a distribution valve, pushing a piston and a hammer head to move up and down to play a hammering role, and are suitable for various free forging: such as stretching, upsetting, punching, shearing, twisting, bending, etc.

An anvil is provided below the hammer head in the air hammer apparatus for placing a workpiece and receiving an impact of the falling of the hammer head. Most of the air hammer anvils in the prior art are fixed integral structures, and have the advantages of stability, simplicity in processing and manufacturing and the like. However, since the anvil is subjected to impact at high temperature for a long period of time, the upper surface of the anvil is easily damaged and is rapidly consumed, so that the anvil is frequently replaced. The existing integral anvil block needs to be replaced integrally, and only the upper surface of the anvil block needs to be more yellow, so that the material waste is caused, and the replacement cost is also increased.

Detailed Description

For a better understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and the following embodiments.

Example 1

The utility model provides an anvil block structure of air hammer, the on-line screen storage device comprises a base 6, be provided with the hammering block 4 of cuboid form on the base 6, 4 sides of hammering block are arc surface 12, be provided with fixed stopper 5 and curved movable stopper 7 respectively in 4 both sides of hammering block on the base 6, movable stopper 7 is located arc surface 12 one side and the two surface can closely laminate, 7 tops of movable stopper are inwards buckled 90 degrees and are formed curved

hem

8, 12 levels on the arc surface have been seted up can with 8 complex draw-in grooves 9 of hem, curved spout 1 has been seted up on the base 6, 7 bottoms of movable stopper are located spout 1, be provided with on the base 6 and be used for locking movable stopper 7 and make its locking mechanical system 10 that keeps corresponding with arc surface 12.

The working principle is as follows: when the anvil 4 is normally installed, the movable limiting block 7 and the fixed limiting block 5 are respectively located on two sides of the anvil 4 and are limited and fixed in the left-right direction (shown in the attached drawing figure 1) of the anvil 4, meanwhile, the movable limiting block 7 is arc-shaped and is tightly attached to the arc surface 12 of the anvil 4, the arc-shaped limiting and fixing of the anvil 4 in the front-back direction (shown in the attached drawing figure 1) is realized, and the hem 8 is matched with the clamping groove 9 to realize the limiting and fixing of the anvil 4 in the vertical direction (shown in the attached drawing figure 2). When the anvil 4 needs to be disassembled and replaced, the locking mechanism 10 is opened, the movable limiting block 7 slides along the sliding groove 1 to stagger with the arc surface 12 of the anvil 4, and then the limiting fixation on the left side and the front and back sides of the anvil 4 is removed, so that the anvil 4 is taken down and replaced by the new anvil 4, the movable limiting block 7 is finally made to slide along the sliding groove 1 to be just opposite to the arc surface 12 of the anvil 4, the folded edge 8 enters the clamping groove 9 again, and the position of the movable limiting block 7 is locked by the re-closing locking mechanism 10.

Example 2

The embodiment is improved on the basis of embodiment 1:

the locking mechanism 10 comprises a screw hole 10.2 horizontally formed in the inner wall of the sliding chute 1, the screw hole 10.2 is located on one side of the arc surface 12, a screw rod 10.1 is arranged in the screw hole 10.2, and a through hole 11 matched with the screw rod 10.1 is formed in the bottom of the movable limiting block 7.

In order to further enhance the stability of the two sides of the anvil 4 close to the fixed limit block 5, the two ends of the fixed limit block 5 are both bent inwards by 90 degrees to form flanges 3 which can be tightly attached to the two sides of the anvil 4.

The tail end of one side of the sliding chute 1 corresponds to one side edge of the arc surface 12, and the other end of the sliding chute bypasses the arc surface 12 of the anvil 4 and extends to one end of the fixed limiting block 5. Activity stopper 7 is located 1 ends of spout when carrying out spacing fixed to hammering block 4, as shown in attached figure 1, like this conveniently looks for the position of activity stopper 7, and then makes locking mechanical system 10 can accurately cooperate with activity stopper 7.

Because the spout 1 makes and exposes outside, so in the normal course of working of air hammer, outside foreign matter, impurity can directly fall into and cause the jam of spout 1 in the spout 1, so all set up the outside row's spout sediment groove 2 of intercommunication on the terminal outside cell wall in spout 1 both sides, utilize the foreign matter in the discharge spout 1 that row's sediment groove 2 can be light, keep activity stopper 7 can normally slide in spout 1.

The top height of fixed stopper 5 and activity stopper 7 all is less than the height of hammering block 4 upper surface to outstanding hammering block 4 makes the work piece accept by hammering block 4 completely, prevents that the work piece from contacting with fixed stopper 5, activity stopper 7 top, and then avoids the impact of beating of air hammer on fixed stopper 5 and activity stopper 7.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited thereto, the protection scope of the present invention is defined by the claims, and all structural changes equivalent to the contents of the description and drawings of the present invention should be included in the protection scope of the present invention.
