Description

Air hammer of forging piece easily overturns

Technical Field

The utility model relates to a metal forging equipment, more specifically say, it relates to an air hammer of forging piece easily overturns.

Background

An Air Hammer (Air Hammer) is one type of free forging machine. A driving mechanism is arranged in the frame and comprises a compression cylinder, a distribution valve and a working cylinder. The compression cylinder compresses air, and the air is sent into the working cylinder through the distribution valve, so that the piston and the hammer head are pushed to move up and down to play a hammering role, the operation is flexible, and the pneumatic hammer is widely applied to the production of small and medium-sized forgings, such as the production of valves or valve body accessories.

The prior Chinese patent with the publication number of CN204620972U discloses an air hammer, which comprises a frame, wherein a hammer head and an anvil block positioned below the hammer head are arranged on the frame, and the hammer head is connected with a power mechanism (a working cylinder) in the frame. When the forging piece is beaten, an operator is required to clamp the high-temperature heated forging block by using a holding clamp and transfer the forging block to an anvil block of an air hammer; then, under the action of the driving mechanism, the hammer head moves up and down in the vertical direction, and the hammer head hammers the forged block by utilizing the gravity and the impact kinetic energy in the downward moving process to complete the hammering forming of the forged block.

The use of the air hammer requires an operator to manually turn the forging block in cooperation with the action of the hammer head so as to finish forging different sides of the forging block. The turning-over operation of the small forging block is usually simpler and easier, while the turning-over difficulty of the large forging block is increased due to the heavy weight, so that the turning-over operation is not facilitated for operators.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

an air hammer for easily turning a forging block, referring to fig. 1, comprises a frame 1, wherein a hammer head 11 capable of performing linear reciprocating motion along a vertical direction under the driving of an internal driving mechanism is arranged on the frame 1. An anvil block 12 is arranged right below the hammer 11, and a cushion block 13 is arranged on the top surface of the anvil block 12. And placing the heated forging block on a cushion block 13, and beating and tamping the forging block by utilizing the repeated motion of the hammer head 11 so as to form the workpiece.

Referring to fig. 1 and 2, the anvil block 12 is provided with a pillar 2 at a side of the pad 13 away from the frame 1, and the pillar 2 is disposed perpendicular to the anvil block 12. The top of stand 2 is equipped with the supporting shoe 3 of the C style of calligraphy that an opening deviates from stand 2, also can set the supporting shoe 3 into the V font as required. Balls 4 are uniformly distributed on the inner circumferential side surface of the supporting block 3. In forging the piece and forging the forming process, when needing to carry out the turn-ups to forging the piece for the body of rod part inlay card that grips of centre gripping forging piece usefulness is in supporting shoe 3 department, regard as the strong point with supporting shoe 3, utilize lever principle, press the end of gripping that grips of gripping the clamp and can easily raise and forge the piece, rotate grip press from both sides and can realize the turn-ups to forging the piece, greatly increased the security and the convenience of turn-ups operation among the forging the forming process of forging the piece.

Referring to fig. 2 and 3, a fixing plate 5 is provided at a bottom end of the pillar 2, and the pillar 2 is disposed perpendicular to the fixing plate 5. The four corners of the fixing plate 5 are all provided with a fixing bolt 51, when the upright post 2 is installed, the fixing plate 5 is adjusted to a proper position, and the fixing bolt 51 is screwed, so that the fixing bolt 51 is inserted into the anvil block 12. In order to increase the connection stability between the upright post 2 and the fixing plate 5, a triangular rib plate 23 is respectively arranged around the upright post 2, and two right-angle sides of the triangular rib plate 23 are respectively connected with the upright post 2 and the fixing plate 5.

Referring to fig. 3, the upright 2 includes a vertical rod 21 and an insertion rod 22, the insertion rod 22 is inserted into the vertical rod 21, and the insertion depth of the insertion rod 22 into the vertical rod 21 can be adjusted by drawing the insertion rod 22. In this embodiment, the cross-sectional shapes of the inserting rod 22 and the vertical rod 21 are both rectangular, so that when the inserting rod 22 is pulled, the inserting rod 22 and the vertical rod 21 cannot rotate relatively.

Referring to fig. 3 and 4, a bolt 211 is inserted into the vertical rod 21 along a direction perpendicular to the length direction of the vertical rod 21, and a limit block is disposed at one end of the bolt 211. The cross section of the plug 211 is regular hexagon, and the plug rod 22 is provided with a plurality of through insertion holes 221 which are vertical to the length direction of the plug rod 22. The insertion holes 221 are equally spaced along the length direction of the insertion rod 22, and the cross-sectional shape of the insertion holes 221 is the same as that of the insertion pins 211. The non-circular cross-section of the release pin 211 is matched with the insertion hole 221, so that the stability is better, and the release pin is not easy to rotate or loosen. After the inserting rod 22 is pulled to a proper position, the inserting pin 211 is inserted into the inserting hole 221, and the position of the inserting rod 22 can be locked.

Referring to fig. 4, in order to increase the locking stability of the insertion rod 22, a movable plate 212 is provided in the inner cavity of the vertical rod 21. A compression spring 213 is disposed between the movable plate 212 and the bottom wall of the inner cavity of the vertical rod 21. When the inserting rod 22 is inserted, the movable plate 212 is pushed downwards, and the compression spring 213 is compressed; after the plug 211 is locked to the inserted link 22, the inserted link 22 always tends to be separated from the vertical rod 21 due to the compression spring 213, so that the plug 211 is not easy to loose and separate from the insertion hole 221.
