Description

Technical Field

[0001] This utility model relates to the field of press technology, and in particular to a rapid lifting device for the mold repair space of a high-speed press. Background Technology

[0002] Existing high-speed presses mainly consist of a mechanical transmission and frame, a hydraulic system, a pneumatic system, and an electrical system. The mechanical transmission and frame include the machine frame, main drive system, die height adjustment system, and rapid lifting system. Due to the short stroke and high stamping frequency of high-speed presses, when the die needs maintenance or repair, traditional operations require disassembling the entire die set from the press, repairing it, and then reinstalling and debugging it. This process has significant drawbacks:

[0003] 1. Low efficiency: The disassembly and assembly of molds takes a long time, and frequent operations seriously affect the continuity of production;

[0004] 2. Increased costs: Frequent manual intervention, long equipment downtime, and high overall maintenance costs. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a rapid lifting device for the mold repair space of a high-speed press.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: A high-speed press mold repair space rapid lifting device includes a slider for mounting the upper mold, a piston rod is provided in the slider, one end of the piston rod is connected to the press frame, and the other end extends into the oil chamber to be movably sealed therein. When the hydraulic oil in the oil chamber is emptied, the slider drives the upper mold to lift; when the oil chamber is filled with hydraulic oil, the slider drives the upper mold to run and cooperate with the lower mold for production.

[0007] In the above scheme, preferably, the press frame includes a connector, which is fixedly connected to the top of the piston rod.

[0008] In the above scheme, preferably, the piston rod is provided with a first channel, and the first channel is sealed to the second channel in the connector.

[0009] In the above scheme, preferably, the slider is fixedly connected to the threaded ring, and the threaded ring is matched with a limiting member inside.

[0010] In the above scheme, preferably, the piston rod includes a rod body and a piston component, the rod body is slidably disposed on the limiting member and the piston component is limited by the limiting member.

[0011] In the above scheme, preferably, the piston component is provided with several grooves, and a sealing block is provided in the grooves.

[0012] In the above scheme, preferably, a third channel is provided below the oil chamber, and the oil chamber is connected to the hydraulic system through various channels. The hydraulic system is used to change the state of the hydraulic oil in the oil chamber.

[0013] In the above scheme, preferably, it also includes a pneumatic balancer, which is used to maintain the working balance of the slider.

[0014] The beneficial effects of this invention are as follows: By draining the liquid from the oil chamber through the hydraulic system, the slider, driven by the pneumatic balancer, moves the upper mold upwards rapidly. Without disassembling the mold, the upper mold is quickly raised by 70-100mm, providing sufficient operating space between the upper and lower molds for mold inspection and repair, while also reducing costs. Simultaneously, when the slider is unexpectedly overloaded, the oil chamber, in conjunction with the piston rod, can provide overload protection, buffering the upper mold within a certain range.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-5 A high-speed press mold repair space rapid lifting device includes a slider 1 for mounting the upper mold, a piston rod 2 penetrating the interior of the slider 1, and a hydraulic drive system.

[0021] Specifically, the piston rod 2 includes a piston component 22 and a rod body 21. The top of the piston rod 2 is fixed to the press frame 3 by a connector 5, that is, the rod body 21 is fixed to the press frame by the connector 5. The connector 5 is provided with several circumferentially arranged through holes and is fixed to the press frame 3 by a screw. The rod body 21 is fixed to the connector 5 by a screw.

[0022] Furthermore, the piston member 22 at the bottom of the piston rod 2 extends into the oil chamber 4 inside the slider 1 and forms a movable seal. This allows the slider 1 and the piston member 22 to be displaced relative to each other. Furthermore, the adaptability is achieved by changing the hydraulic oil pressure state in the oil chamber 4.

[0023] The piston rod 2 has a through-passage 6 inside, which is sealed and connected to the second channel 7 inside the connector 5, forming a continuous hydraulic oil circuit. Meanwhile, the bottom of the oil chamber 4 is provided with a third channel 11. The press includes a hydraulic system that connects these three channels. Specifically, the oil chamber 4 is connected to an external hydraulic system via hydraulic pipelines to control the filling and discharging of hydraulic oil within the oil chamber 4, thereby achieving pressure changes within the oil chamber 4.

[0024] Specifically, when it is necessary to increase the mold repair space, that is, temporarily separate the upper and lower molds, the hydraulic system completely empties the hydraulic oil in the oil chamber 4. At this time, the slider 1 drives the upper mold to rise upward under its own weight or external auxiliary force, so that a sufficient maintenance gap is formed between the upper and lower molds, which is convenient for mold adjustment or maintenance.

[0025] The top of the oil chamber 4 of the slider 1 is provided with a threaded ring 8, and a limiting member 9 is threadedly connected to the threaded ring 8. The rod 21 slides in the limiting member 9, and the piston 22 is restricted by the limiting member 9 to prevent it from disengaging. At the same time, the piston 22 has multiple annular grooves 10 circumferentially formed, and sealing blocks are embedded in the grooves 10 to enhance the sealing of the oil chamber 4.

[0026] Furthermore, the press also includes a pneumatic balancer disposed on the side of the slider 1, which continuously provides a pneumatic balancing force to counteract the movement of the slider 1 or lock the slider 1 in a stationary state.

[0027] When the press is working normally, the oil chamber 4 is filled with high-pressure oil, that is, the slider 1 and the piston rod 2 are essentially rigidly connected, and the upper and lower dies of the press cooperate normally to achieve production.

[0028] When mold maintenance is required, the hydraulic oil in oil chamber 4 is drained, and the balancer air pressure is increased, which raises slide block 1. The piston stroke in oil chamber 4 is the rapid lifting stroke of slide block 1. After mold maintenance is completed, the balancer air pressure is restored to the equilibrium pressure, and the hydraulic system is started to refill the hydraulic oil in oil chamber 4 to restore the press operation.

[0029] Furthermore, during the operation of the press, when overloaded, i.e. when the filling pressure is lower than the nominal pressure, it can also be used as an overload protection oil chamber 4 to buffer the upper mold within a certain range and protect the upper mold.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
