Description

An electro-hydraulic hammer electro-controlled strike control system Technical Field

[0001] This utility model relates to the field of forging equipment technology, specifically to an electro-hydraulic hammer electro-controlled impact control system. Background Technology

[0002] Electro-hydraulic hammers are a new type of forging equipment, available in single-arm and double-arm configurations. Their working principle is the same as that of electro-hydraulic power heads, but the machine body differs from the original vacuum hammer. The hammer head guide is replaced with an "X" guide rail, allowing the guide rail gap to be adjusted to within 0.3mm, significantly improving the guiding accuracy of the electro-hydraulic hammer, enhancing forging quality, and extending hammer rod life. Electro-hydraulic hammers are the most widely used equipment in forging, mainly divided into free forging and die forging types, and are widely applied in the precision forging and hot forging blank industries.

[0003] Existing electro-hydraulic hammer equipment operates in a very harsh environment, still requiring an operator to operate a lever mechanism to control the hammer's movements. The high temperature, high intensity, high noise, and low safety during the forging process hinder the industry's development. Implementing electronic and programmable hammering would move the hammer operation from the hammer edge to a more comfortable operating room, significantly improving safety, isolating production noise, eliminating heat radiation damage, and allowing one person to operate both the hammer and the manipulator simultaneously, reducing manpower, increasing efficiency, and enhancing production competitiveness. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an electro-hydraulic hammer electro-controlled impact control system, which has the advantages of improving operator comfort, enabling one person to operate the machine simultaneously, reducing manpower and increasing efficiency, and improving production competitiveness, thus solving the problems mentioned in the background technology.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5. An electro-hydraulic hammer electro-controlled impact control system includes an electro-hydraulic hammer body 1. The inner cavity of the electro-hydraulic hammer body 1 is provided with a pilot-controlled servo-controlled main impact valve 6. A connecting mechanism 7 is installed on the top of the pilot-controlled servo-controlled main impact valve 6. A pneumatic actuator 2 is installed at the end of the connecting mechanism 7 away from the pilot-controlled servo-controlled main impact valve 6. A pneumatic component box 3 is provided on the right side of the electro-hydraulic hammer body 1. An operating table 4 is provided on the right side of the pneumatic component box 3. An analog foot pedal 5 is provided on the right side of the operating table 4.

[0022] In the above structure, the pneumatic proportional valve in the pneumatic component box 3 is controlled by the analog foot pedal 5. The pneumatic proportional valve controls the pneumatic actuator 2 to move up and down. The air pressure is proportional to the stroke position. The movement of the pneumatic actuator 2 drives the connecting mechanism 7 to move. Thus, the connecting mechanism 7 connects to the pilot-controlled servo-controlled main striking valve 6 to realize the electro-hydraulic hammer's slow up and slow down, suspension hammer, striking, and lifting hammer processes.

[0023] In a preferred embodiment: the connecting mechanism 7 includes a bridge plate 701, a connecting pipe 702 is movably sleeved on the outer edge of the bridge plate 701, a support pipe 703 is movably sleeved on the outer edge of the middle part of the bridge plate 701, and the support pipe 703 is fixedly mounted on the electro-hydraulic hammer body 1.

[0024] In the above structure, the pneumatic actuator 2 is controlled to move left and right up and down by the pneumatic proportional valve. At this time, the connecting pipe 702 moves up and down. When the connecting pipe 702 moves downward, it drives the bridge plate 701 to move. The connection end between the bridge plate 701 and the connecting pipe 702 will move downward. When the connecting pipe 702 moves upward, it drives the bridge plate 701 to move. The connection end between the bridge plate 701 and the connecting pipe 702 will move upward.

[0025] In a preferred embodiment: the end of the connecting pipe 702 away from the bridge plate 701 is connected to the pneumatic actuator 2, and the end of the bridge plate 701 away from the connecting pipe 702 is connected to the pilot-controlled servo-controlled main strike valve 6.

[0026] In the above structure, the pneumatic actuator 2 drives the connecting pipe 702 to move up and down, the bridge plate 701 moves on the support pipe 703, and the bridge plate 701 drives the pilot-controlled servo-controlled main striking valve 6 to slowly move up, slowly move down, suspend the hammer, strike and lift the hammer. The dynamic movement of the hammer is achieved by controlling the amount of air through the air pressure proportional valve in the pneumatic component box 3.

[0027] In a preferred embodiment: an analog handle 8 is mounted on the top of the control panel 4, and the analog handle 8 is electrically connected to the pneumatic component box 3;

[0028] In the above structure, the pneumatic proportional valve in the pneumatic component box 3 is controlled by the analog handle 8. The pneumatic proportional valve controls the pneumatic actuator 2 to move up and down. The air pressure is proportional to the stroke position. The movement of the pneumatic actuator 2 drives the connecting mechanism 7 to move. Thus, the connecting mechanism 7 connects to the pilot-controlled servo-controlled main striking valve 6 to realize the electro-hydraulic hammer's slow up and slow down, suspension, striking, and lifting processes.

[0029] In a preferred embodiment: the analog foot pedal 5 is electrically connected to the pneumatic component box 3, and the pneumatic component box 3 is connected to the pneumatic actuator 2 via an air pipe;

[0030] In the above structure, the analog foot pedal 5 controls the pneumatic proportional valve in the pneumatic component box 3, making the control method of the pneumatic proportional valve simple. The operator can press the analog foot pedal 5 while standing or sitting. The controlled gas in the pneumatic component box 3 will enter the pneumatic actuator 2 through the air pipe. This gas controls the pneumatic actuator 2, so that the pneumatic actuator 2 can drive the connecting pipe 702 to move up and down.

[0031] In a preferred embodiment: the pneumatic actuator 2 is fixedly mounted on the electro-hydraulic hammer body 1, and the pneumatic actuator 2 is located at the bottom of the electro-hydraulic hammer body 1;

[0032] In the above structure, by installing the pneumatic actuator 2 on the electro-hydraulic hammer body 1, less material is needed for the connecting pipe 702, the distance between the pneumatic actuator 2 and the pilot-controlled servo-controlled main strike valve 6 is shorter, and the pneumatic actuator 2 located below is also easier to maintain.

[0033] Working principle: During use, the analog handle 8 or analog foot pedal 5 on the operating table 4 controls the pneumatic proportional valve in the pneumatic component box 3. The pneumatic proportional valve controls the pneumatic actuator 2 to move up and down. The air pressure is proportional to the stroke position. The pneumatic actuator 2 drives the connecting pipe 702 to move up and down, thereby driving the pilot-controlled servo-controlled main striking valve 6 to move through the bridge plate 701. This realizes the electro-hydraulic hammer's slow up and slow down, suspension, striking, and lifting processes. The pneumatic component box 3 is connected to the pneumatic actuator 2 through an air pipe. At this time, the analog foot pedal 5, operating table 4, analog handle 8 and pneumatic component box 3 can be placed in a sealed and soundproof room. The operator can operate the electro-hydraulic hammer body 1 in the room, which greatly improves the operator's working environment.
