Abstract
Description
Technical Field
[0001] This utility model relates to the field of air hammer technology, and in particular to an air hammer device for forging. Background Technology
[0002] An air hammer is a type of free forging machine. A compressed air cylinder compresses air, which is then fed into the working cylinder through a distribution valve. This pushes the piston and hammer head to move up and down, producing a hammering effect. It is flexible in operation and suitable for various free forging processes, such as stretching, upsetting, punching, shearing, forging welding, twisting, and bending. Various open-die forgings can be performed using a die pad.
[0003] In existing air hammer technology, the hammer head is prone to wear and damage after prolonged use. Since the hammer head is usually bolted inside the air hammer, it is inconvenient to replace the hammer head. Therefore, we propose an air hammer device for forging to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the wear and tear on the hammer head of an air hammer after prolonged use, and the inconvenience of replacing the hammer head caused by bolts that are usually fixed inside the air hammer.

[0011] Two threaded plates are symmetrically slidably connected to the left and right sides of the air hammer, and the inner walls of the two threaded plates are threadedly connected to the outer walls of the corresponding threaded rods. Two transmission plates are slidably connected to the bottom of the corresponding support plates. Two transmission rods are rotatably connected to the left and right sides of the air hammer, and the rear sides of the two transmission rods are slidably connected to the front sides of the corresponding transmission plates.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0026] Example
[0027] Reference Figure 1-Figure 4 An air hammer device for forging, comprising a base 1;
[0028] The air hammer 2, hammer head 3, support plate 4, threaded rod 5, and fixing plate 11 are provided. The air hammer 2 is fixedly connected to the top of the base 1, and the hammer head 3 is movably in contact with the bottom of the air hammer 2. There are two support plates 4, two threaded rods 5, and two fixing plates 11. The two support plates 4 are fixedly connected to the left and right sides of the air hammer 2, and the two threaded rods 5 are rotatably connected to the top of the corresponding support plates 4. Fixing grooves are provided on both the left and right sides of the hammer head 3, and the two fixing plates 11 are engaged with the corresponding fixing grooves.
[0029] The fixing mechanism is connected to the fixing plate 11 and is used to fix the hammer head 3.
[0030] The above-mentioned mechanism allows the air hammer 2 to easily move the hammer head 3 to forge the workpiece, the threaded rod 5 to easily rotate the fixing mechanism, the fixing mechanism to easily move the fixing plate 11, and the fixing plate 11 to easily fix the hammer head 3 through the cooperation of the fixing groove.
[0031] As a preferred embodiment of the present invention, the fixing mechanism includes: two threaded plates 6, two transmission rods 8 and two transmission plates 9;
[0032] Two threaded plates 6 are symmetrically slidably connected to the left and right sides of the air hammer 2, and the inner walls of the two threaded plates 6 are threadedly connected to the outer walls of the corresponding threaded rods 5. Two transmission plates 9 are slidably connected to the bottom of the corresponding support plates 4. Two transmission rods 8 are rotatably connected to the left and right sides of the air hammer 2, and the rear sides of the two transmission rods 8 are slidably connected to the front sides of the corresponding transmission plates 9. The sides of the two transmission plates 9 that are close to each other are fixedly connected to the sides of the two fixed plates 11 that are far apart from each other. The rotation of the threaded rods 5 will drive the threaded plates 6 to move upward. The movement of the threaded plates 6 will drive the limit shaft 7 to move. The movement of the limit shaft 7 will push the transmission rods 8 to rotate. At this time, the rotation of the transmission rods 8 will push the transmission plates 9 to move. The movement of the transmission plates 9 will drive the fixed plates 11 to move and disengage from the fixed groove, thereby unlocking the hammer head 3.
[0033] As a preferred embodiment of this utility model, the front sides of the two threaded plates 6 are fixedly connected to the limiting shafts 7, and the two transmission rods 8 are hollow structures. The inner walls of the two transmission rods 8 are slidably connected to the outer walls of the corresponding limiting shafts 7. The threaded plates 6 can easily drive the limiting shafts 7 to move, and the limiting shafts 7 can easily push the transmission rods 8 to rotate.
[0034] As a preferred embodiment of this utility model, a transmission shaft is fixedly connected to the rear side of each of the two transmission rods 8, and a transmission groove is opened on the front side of each of the two transmission plates 9. There are two transmission shafts and two transmission grooves. The outer wall of each transmission shaft is slidably connected to the inner wall of the corresponding transmission groove.
[0035] As a preferred embodiment of this utility model, the bottom of the support plate 4 is fixedly connected with a limiting rod 10, and the two limiting rods 10 pass through the corresponding transmission plates 9. The limiting rods 10 facilitate the limiting of the transmission plates 9, so that the transmission plates 9 can move laterally in a stable manner.
[0036] As a preferred embodiment of this utility model, a knob is fixedly connected to the top of each of the two threaded rods 5, which allows the threaded rods 5 to be rotated, thereby driving the fixed plate 11 to move.
[0037] It should be noted that the specific model of air hammer 2 used is to be selected by those skilled in the art, and the air hammer 2 mentioned above are all existing technologies, which will not be elaborated upon in this solution.
[0038] The working principle of this utility model is as follows: In actual use, when a workpiece needs to be forged, the workpiece is placed on top of the base 1 and positioned below the hammer head 3. The air hammer 2 is then activated, and the hammer head 3 is moved by the air hammer 2 to forge the workpiece. When the hammer head 3 needs to be replaced, a knob is rotated. Rotation of the knob rotates the threaded rod 5, which in turn moves the threaded plate 6 upwards. The movement of the threaded plate 6 moves the limiting shaft 7, which in turn pushes the transmission rod 8 to rotate. The rotation of the transmission rod 8 then pushes the transmission plate 9 to move. At this time, the two transmission plates 9 move to opposite sides, while the limiting rod 10 moves the transmission plate 9... Limiting the movement of the transmission plate 9 allows it to move laterally in a stable manner. The movement of the transmission plate 9 causes the fixing plate 11 to move and disengage from the fixing groove, thus unlocking the hammer head 3. At this point, the hammer head 3 can be removed. Place the hammer head 3 to be installed at the bottom of the air hammer 2 and align the fixing groove with the fixing plate 11. Then, rotate the threaded rod 5 to reset it. The rotation of the threaded rod 5 causes the threaded plate 6 to move downward. The downward movement of the threaded plate 6 causes the limiting shaft 7 to move, thereby causing the transmission rod 8 to rotate and reset. When the transmission rod 8 rotates, it causes the transmission plate 9 to move, causing the two fixing plates 11 to move closer to each other and engage with the fixing groove to fix the hammer head 3, thus achieving the effect of disassembling and replacing the hammer head 3.
[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
