Description

Technical Field

[0001] This utility model relates to the field of electro-hydraulic hammer technology, and in particular to an electro-hydraulic hammer with a protective device. Background Technology

[0002] Electro-hydraulic hammers are highly efficient and energy-saving forging equipment widely used in the forging and pressing of metal materials. However, during the operation of an electro-hydraulic hammer, the high-speed movement and frequent impacts of the hammer head may generate flying metal chips, oxide scale, and dust, posing a threat to the safety of operators. Therefore, designing a reliable protective device is crucial.

[0003] Chinese utility model patent application number 202322153620.6 discloses a protective device for an electro-hydraulic hammer, including an electro-hydraulic hammer body. A slot is formed on the outer side of the electro-hydraulic hammer body, and a first fixing rod is installed inside the slot. The device also includes a protective structure disposed on the outer surface of the first fixing rod. The protective structure includes a protective shell, which is sleeved with the first fixing rod. A second locking block is installed at the bottom of the protective shell. The device also includes a base, with a mounting bracket installed on the outer side of the base. The second fixing rod is installed inside the mounting bracket, and the first locking block and a second spring are sleeved on the outer surface of the second fixing rod. Because the second spring is in a compressed state, it applies an elastic force to the first locking block. This allows the protective shell to be limited through the cooperation between the first and second locking blocks, thereby protecting the workpiece and preventing metal shavings from splashing.

[0004] However, in this technical solution, during the electro-hydraulic hammer forging process, the protective structure is too close to the electro-hydraulic hammer and the height of the protective structure is too low. This results in metal fragments hitting the protective shell and bouncing back onto the forging table, leading to a poor forging effect; or metal fragments flying over the protective structure and splashing onto the faces of workers outside, causing injury to the workers.

[0005] Therefore, it is necessary to solve the above problems by using an electro-hydraulic hammer with a protective device. Utility Model Content

[0006] The purpose of this invention is to provide an electro-hydraulic hammer with a protective device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an electro-hydraulic hammer with a protective device, comprising a mounting base, a fixing component and a forging table disposed on the mounting base, a protective component disposed on the outer side of the forging table, a detection component disposed on the side of the protective component away from the forging table, and a control center disposed on one side of the fixing component.

[0008] Preferably, the protective component includes an electrically operated telescopic plate, the top of which is provided with an arc-shaped baffle, and detection components are respectively provided on the electrically operated telescopic plate and the arc-shaped baffle.

[0009] Preferably, the electric telescopic plate has an extension plate on the side near the forging table, and the extension plate is fixedly installed on the mounting base.

[0010] Preferably, the detection component includes symmetrically arranged support plates, one of which is provided with an infrared transmitter and the other support plate is provided with a receiver.

[0011] Preferably, the fixing component is disposed on one side of the forging table, and the protective component is disposed on the other three sides of the forging table, and neither the fixing component nor the protective component is in contact with the forging table.

[0012] Preferably, the fixing component includes a fixing arm, the top end of which is arc-shaped and extends above the forging table, and an auxiliary arm is provided at the arc-shaped end of the fixing arm, on which an electric hydraulic cylinder is provided.

[0013] Preferably, the output shaft of the electric hydraulic cylinder passes through the auxiliary arm and is connected to the electro-hydraulic hammer body, which is located above the forging table and is coaxial with the forging table.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, by setting the protective component at a certain distance from the forging table, metal fragments flying out during the forging hammering process are prevented from hitting the protective shell and bouncing back onto the forging table, thus reducing the forging effect. By setting a detection component, it is possible to detect whether there are workers standing outside the protective component. After receiving the signal, the control center controls the protective component to adjust and block metal fragments from flying out, preventing them from splashing onto the workers' faces and causing injury, thus ensuring the safety of personnel.

[0016] 2. In this utility model, an infrared transmitter and receiver are used to determine whether there are workers standing outside the electric telescopic platform. If the receiver does not receive a signal from the infrared transmitter, it means that there are currently people standing outside the electric telescopic platform. The control center controls the electric telescopic platform to extend, driving the arc-shaped baffle to rise to its highest position to prevent metal fragments from flying onto the workers' faces and causing injury, thus ensuring the safety of the workers.

[0017] 3. In this utility model, by setting two detection components, the control center can determine whether there are staff members standing on the outside of the electric telescopic platform by whether the receiver receives the signal emitted by the infrared transmitter. In addition, after the control center determines that there are staff members, when controlling the electric telescopic platform to extend, it can also determine whether the staff member's face is completely blocked by the signal received by the receiver. This allows the electric telescopic platform to adjust the extension amount in a timely manner according to the height of the staff member, avoiding excessive extension and energy waste.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] To address the issues of metal debris bouncing back onto the forging table 5 after hitting the protective shell, resulting in poor forging performance, and metal debris flying over the protective structure and splashing into the faces of workers outside, causing injury, the following embodiments are proposed.

[0025] This utility model provides, for example Figures 1 to 4The electro-hydraulic hammer with a protective device shown includes a mounting base 1, a fixing component 2 and a forging table 5 on the mounting base 1, a protective component 6 on the outer side of the forging table 5, a detection component 7 on the side of the protective component 6 away from the forging table 5, and a control center 4 on one side of the fixing component 2. The control center 4 is electrically connected to the electronic components in this utility model. Whether the infrared transmitter 702 and the receiver 703 receive a signal is transmitted to the control center 4 via an electrical signal. The control center 4 adjusts the protective component 6 according to the received signal. In addition, the operator can issue opening and closing commands to the electric hydraulic cylinder 202 and the electric telescopic plate 601 through the control center 4. The fixing component 2 is set on one side of the forging table 5, and the protective component 6 is set on the other three sides of the forging table 5. The fixing component 2 and the protective component 6 do not contact each other with the forging table 5. The fixing component 2 includes a fixing arm 201. A power supply device is set in the vertical section of the fixing arm 201. The power supply device provides power support to all electronic components in this utility model. The top of the fixing arm 201 is set in an arc shape and extends to the top of the forging table 5. An auxiliary arm 203 is set at the arc end of the fixing arm 201. An electric hydraulic cylinder 202 is set on the auxiliary arm 203. The output shaft of the electric hydraulic cylinder 202 passes through the auxiliary arm 203 and is connected to the electro-hydraulic hammer body 3. The electro-hydraulic hammer body 3 is located above the forging table 5 and is coaxial with the forging table 5.

[0026] In use, the metal to be forged is placed on the forging table 5 by external mechanical equipment. The operator starts the electric hydraulic cylinder 202 through the control center 4. The output end of the electric hydraulic cylinder 202 extends, driving the electro-hydraulic hammer body 3 to descend and hammer the metal on the forging table 5 for forging.

[0027] By placing the protective component 6 at a certain distance from the forging table 5, metal fragments flying out during the forging hammering process are prevented from hitting the protective shell and bouncing back onto the forging table 5, thus reducing the forging effect. By setting up the detection component 7, it can detect whether there are workers standing outside the protective component 6. After receiving the signal, the control center 4 controls the protective component 6 to adjust, blocking metal fragments from flying out and preventing them from splashing onto the workers' faces, thus ensuring the safety of the personnel.

[0028] like Figure 3As shown, the protective component 6 includes an electric telescopic plate 601, with an arc-shaped baffle 603 at its top. The arc-shaped baffle 603 is made of transparent material. The electric telescopic plate 601 includes a primary plate and a secondary plate, which are also made of transparent material, allowing workers to observe the forging process of the electro-hydraulic hammer body 3 through the primary and secondary plates even when the electric telescopic plate 601 is fully extended. The arc-shaped baffle 603 is located on top of the primary plate. Detection components 7 are respectively installed on the electric telescopic plate 601 and the arc-shaped baffle 603. An extension plate 602 is provided on the side of the electric telescopic plate 601 near the forging table 5, and the extension plate 602 is fixedly installed on the mounting base 1. The detection component 7 includes symmetrically arranged support plates 701, with an infrared emitter 702 installed on each support plate 701. In the absence of personnel... When standing outside the protective component 6, the receiver 703 can receive the signal emitted by the infrared transmitter 702. At this time, the control center 4 receives a signal indicating that the receiver 703 has successfully received the signal and determines that no one is currently standing outside the protective component 6. When a person is standing outside the protective component 6, their body blocks the signal emitted by the infrared transmitter 702, and the receiver 703 cannot receive the signal emitted by the infrared transmitter 702. At this time, the control center 4 receives a signal indicating that the receiver 703 has failed to receive the signal and determines that someone is currently standing outside the protective component 6. Another receiver 703 is installed on another support plate 701. The two symmetrically arranged support plates 701 form a group. One group of support plates 701 is installed at both ends of the electric telescopic plate 601, and the other group of support plates 701 is installed at both ends of the arc-shaped baffle 603.

[0029] When it is necessary to check the forging status of the electro-hydraulic hammer body 3 during use, the worker will stand outside the protective component 6. At this time, the receiver 703 cannot receive the signal emitted by the infrared transmitter 702. The control center 4 receives the signal of reception failure from the receiver 703 and determines that there is a worker standing outside the protective component 6. At this time, the control center 4 issues an instruction to the electric telescopic plate 601 to extend the electric telescopic plate 601, so that both the first-level plate and the second-level plate are raised to their highest positions, and the arc-shaped baffle 603 is raised to its highest position to provide a barrier for the worker and prevent metal fragments from flying out and scratching the worker.

[0030] The system uses an infrared transmitter 702 and a receiver 703 to determine whether there are workers standing outside the electric telescopic platform 601. If the receiver 703 does not receive a signal from the infrared transmitter 702, it means that there are people standing outside the electric telescopic platform 601. The control center 4 then controls the electric telescopic platform 601 to extend, causing the arc-shaped baffle 603 to rise to its highest position to prevent metal fragments from flying into the workers' faces and causing injury, thus ensuring the safety of the workers.

[0031] During the raising and lowering of the aforementioned arc-shaped baffle 603, since the height of the staff varies, if the arc-shaped baffle 603 is raised to its highest point for shorter staff, it will cause energy waste. Therefore, the detection component 7 located on the arc-shaped baffle 603 is used to detect whether the staff's face is completely blocked. After receiving the signal, the control center 4 controls the extension of the electric telescopic plate 601 to save energy.

[0032] When the receiver 703 on the curved baffle 603 goes from being unable to receive the signal emitted by the infrared transmitter 702 to being able to receive it, while the receiver 703 on the electric telescopic plate 601 is still unable to receive the signal, it means that the height of the receiver 703 on the curved baffle 603 is now above the worker's head, and the curved baffle 603 has completely blocked the worker's face. The control center 4 receives the signal and controls the electric telescopic plate 601 to stop extending, so that the extension of the electric telescopic plate 601 can be adjusted in time according to the height of the person, saving energy.

[0033] By setting up two detection components 7, the control center 4 determines whether there are staff members standing on the outside of the electric telescopic platform 601 by whether the receiver 703 receives the signal emitted by the infrared transmitter 702. In addition, after the control center 4 determines that there are staff members, when controlling the electric telescopic platform 601 to extend, it can also determine whether the staff member's face is completely blocked by the signal received by the receiver 703. This allows the electric telescopic platform 601 to adjust the extension amount in a timely manner according to the height of the staff member, avoiding excessive extension and energy waste.

[0034] The working principle of this utility model is as follows: First, the electro-hydraulic hammer is started, and the metal to be forged is placed on the forging table 5 through external mechanical equipment. The operator starts the electric hydraulic cylinder 202 through the control center 4. The output end of the electric hydraulic cylinder 202 extends, driving the electro-hydraulic hammer body 3 to descend and hammer the metal on the forging table 5 for forging.

[0035] Secondly, it determines whether there are personnel inspecting the area. When it is necessary to check the forging status of the electro-hydraulic hammer body 3, the personnel will stand outside the protective component 6. At this time, the receiver 703 cannot receive the signal emitted by the infrared transmitter 702, and the control center 4 receives the signal of receiver 703 failing to receive the signal. It is determined that there are personnel standing outside the protective component 6. At this time, the control center 4 issues an instruction to the electric telescopic plate 601 to control the electric telescopic plate 601 to extend, so that both the first-level plate and the second-level plate are raised to their highest positions, and the arc-shaped baffle 603 is raised to its highest position to provide a barrier for the personnel.

[0036] When receiver 703 receives the signal emitted by infrared transmitter 702, control center 4 receives the signal that receiver 703 has successfully received the signal and determines that no personnel are currently standing outside the protective component 6, so there is no need to issue an instruction to electric telescopic plate 601.

[0037] Then, in order to save energy, the extension of the electric telescopic board 601 is adjusted according to the height of the personnel. Specifically, when the receiver 703 on the arc-shaped baffle 603 goes from being unable to receive the signal emitted by the infrared transmitter 702 to being able to receive it, while the receiver 703 on the electric telescopic board 601 is still unable to receive the signal, it means that the height of the receiver 703 on the arc-shaped baffle 603 is now above the head of the personnel, and the arc-shaped baffle 603 has completely blocked the face of the personnel, the control center 4 receives the signal and controls the electric telescopic board 601 to stop extending. This allows the extension of the electric telescopic board 601 to be adjusted in a timely manner according to the height of the personnel, avoiding the electric telescopic board 601 indiscriminately raising the arc-shaped baffle 603 to its highest position.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
