Problems solved by technology

Because the elasticity of the elastic swing rod weakens after a period of use, and its life is limited, it is difficult to control its elastic strength. Therefore, it is very unreliable to use an elastic swing rod to increase the speed of the piston, which often causes troubles to work.

Embodiment 1

[0018] Example 1: See attached figure 1 -Attached figure 2 , Attached Figure 5 , The impact component is the hammer 12. However, when the swing member 3 moves backward, it compresses the gas in the first cylinder, stores energy, and at the same time plays a better damping effect on the swing member 3; when the swing member 3 moves forward, the gas in the first gas chamber 10 The expansion releases its stored energy, which increases the speed of the first piston 2 and thereby increases the speed of the connecting member 9, thus generating a strong impact force.

Embodiment 2

[0019] Example 2: See attached image 3 -Attachment 4, attached Figure 6 In order to enhance the impact force, the impact component is set as a second cylinder, and the second cylinder includes a second cylinder liner 5 and a second piston 6 slidingly inserted in the second cylinder liner 5. One of the second cylinder liner 5 and the second piston 6 is connected to the connecting member 9, and is attached image 3 -In the embodiment shown in FIG. 4, the connecting member 9 is connected to the second cylinder liner 5, and the second piston 6 and the second cylinder liner 5 form a closed The second air chamber 11. When the swing member 3 moves backward, the gas in the first gas chamber 10 is compressed to store energy, similar to the first embodiment; when the swing member 3 moves forward, the second cylinder sleeve 5 moves forward to make the second gas The gas in the chamber 11 is pressurized to store energy, which will increase the speed of the second piston 6 so that the impact ...

Abstract

The invention is an energy storing and punching mechanism for electric hammer, which includes a hammer anvil, punching part back of the anvil, and pendulum part. The back part of the punching part is connected to one connector; one end of the pendulum part is connected to the connector. The back side of the connector is arranged with the first cylinder, the first cylinder includes the first cylinder cover and the first piston, one of the first pistons and the first cylinder cover is connected to the connector. When the pendulum part moves backwards, the air in the first cylinder is squeezed and stores the energy, when the pendulum part moves forwards, the air is swelled and release energy to accelerate the first piston, thus it generate strong punching force to the hammer anvil.

Description

Technical field [0001] The invention relates to an electric hammer, in particular to an energy storage impact mechanism of the electric hammer. Background technique [0002] The existing electric hammer usually uses a moving cylinder to increase the speed of the piston so that the anvil has the effect of increasing the impact capacity. That is, a cylinder is arranged on the back of the anvil, and the piston is adjacent to the anvil, and a cylinder is arranged on the back of the cylinder. The pendulum rod and the cylinder sleeve are connected with the pendulum rod. The pendulum rod is driven by a transmission mechanism to reciprocate. When the cylinder sleeve moves with the pendulum rod, the piston also reciprocates, so that the piston impacts the hammer anvil, as attached Figure 8 Shown. Although this method can produce a certain impact on the anvil, but the acceleration effect of the energy storage gas on the piston is relatively limited, so the impact of...
