Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, specifically a protective structure for a hydraulic press. Background Technology

[0002] A hydraulic press, also known as an oil press, is a machine that uses the static pressure of a liquid to process products made of metal, plastic, rubber, wood, powder, etc. It is commonly used in pressing and forming processes.

[0003] In response, Chinese patent application number CN202321887933.8 discloses a safety protection structure for a hydraulic press, including a base plate. A hydraulic device is installed on the upper surface of the base plate, and a protective cover is fitted onto the hydraulic device. One side of the protective cover has an opening, and a first protective plate is fixedly connected to the two side walls at the upper end of the opening. The two side walls of the opening have sliding grooves. This application utilizes the cooperative arrangement of a threaded rod, a micro motor, and a second protective plate. When in use, the user can place the tool requiring hydraulic pressure into the hydraulic device and simultaneously activate the micro motor to move the slider fitted onto the threaded rod. This slider then moves the second protective plate, sealing the opening on the protective cover. This minimizes the need for manual installation of the cover during use, which is inconvenient and wastes time.

[0004] This hydraulic press can seal the opening on the protective cover by setting a movable second protective plate, which works in conjunction with the first protective plate. However, when the material is subjected to the action of the hydraulic press, it will break and the debris will fall onto the top surface of the base plate. Due to the influence of the device, it will be difficult to clean and cause inconvenience in use.

[0005] Therefore, in order to solve the above problems, a protective structure for a hydraulic press is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a protective structure for a hydraulic press, in order to solve the problem mentioned in the background art that in the prior art, a hydraulic press can seal the opening on the protective cover by setting a movable second protective plate in conjunction with the first protective plate. However, when the material is subjected to the action of the hydraulic press, it will break and the debris will fall onto the top surface of the base plate. Due to the influence of the device, it will be difficult to clean and cause inconvenience in use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for a hydraulic press, comprising: a housing, wherein the front of the housing has an opening for taking out and putting in;

[0008] A protective mechanism is installed inside the box, comprising a fixing block fixedly installed on the bottom inner side of the box. A sloping groove is formed on the top surface of the fixing block, and a grid plate is movably installed inside the sloping groove. A flow guide channel is fixedly installed on the inner wall of the box, and a placement plate is fixedly installed inside the flow guide channel. A through groove is formed at the front end of the top of the grid plate, and a handle is fixedly connected to the front of the grid plate. An electric telescopic rod is fixedly installed on the inner wall of the box, and a protective plate is fixedly connected to the extended end of the electric telescopic rod. A protruding rod is fixedly connected to the bottom surface of the protective plate. A spring is fixedly connected to the rear wall of the grid plate, and a collection box is installed inside the front of the fixing block.

[0009] Preferably, the grid plate is located between the fixing block and the guide channel.

[0010] Preferably, the handle extends through the front of the box.

[0011] Preferably, the protrusion rod is located on the upper side of the through groove, and the protrusion rod is adapted to the through groove.

[0012] Preferably, the rear end of the spring is fixedly connected to the inner wall of the housing.

[0013] Preferably, the collection box is located directly below the inclined groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by installing a movable grid plate on the fixed block, the protrusion rod can move in the through groove when the protective plate is raised and lowered, so as to drive the grid plate to sway back and forth, and the debris accumulated on the grid plate can be discharged downward under the action of inertia, so as to be collected in the collection box, thus realizing the unified collection of debris.

[0015] This invention features a protective mechanism that places materials on a placement plate. Activating the electric telescopic rod lowers the protective plate, which in turn lowers a protruding rod that passes through a slot into a mesh plate. The protective plate blocks the inside of the loading / unloading opening, preventing debris from flying out during processing and ensuring the device's safety. The debris is blocked by the housing and protective plate, and guided by the guide channel, it is collected in an inclined trough and then passes through the mesh plate into a collection box. Activating the electric telescopic rod raises the protective plate, which in turn lowers the protruding rod... As the protruding rod moves within the through groove, it pushes the mesh plate back and forth. In conjunction with the spring, this causes the mesh plate to sway back and forth, allowing debris accumulated on the top surface of the mesh plate to move under the influence of inertia. This ensures that all debris can pass through the mesh plate, keeping its top surface clean. After the protruding rod separates from the through groove, the handle can be manually pulled to move the mesh plate forward, stretching the spring. Releasing the handle then causes the mesh plate to return to its original position under the spring's action, increasing the swaying tendency of the mesh plate and ensuring effective cleaning of debris from its top surface.

A sloping groove 22 is formed on the top surface of the fixing block 21. A grid plate 23 is movably installed inside the sloping groove 22. A flow guide trough 24 is fixedly installed on the inner wall of the housing 1. A placement plate 25 is fixedly installed inside the flow guide trough 24. A through groove 26 is formed at the front end of the top of the grid plate 23. A handle 27 is fixedly connected to the front of the grid plate 23. An electric telescopic rod 28 is fixedly installed on the inner wall of the housing 1. The extended end of the electric telescopic rod 28... A protective plate 29 is fixedly connected, and a protrusion rod 210 is fixedly connected to the bottom surface of the protective plate 29. A spring 211 is fixedly connected to the rear wall of the grid plate 23. A collection box 212 is installed inside the front of the fixing block 21. By installing a movable grid plate 23 on the fixing block 21, the protrusion rod 210 can move in the through groove 26 when the protective plate 29 is raised and lowered, so as to drive the grid plate 23 to swing back and forth. The debris accumulated on the grid plate 23 can be discharged downward under the action of inertia so as to be collected in the collection box 212, thereby realizing the unified collection of debris.

[0026] Furthermore, the grid plate 23 is located between the fixed block 21 and the guide channel 24. The grid plate 23 can move between the fixed block 21 and the guide channel 24. The guide channel 24 can guide debris to move onto the grid plate 23.

[0027] Furthermore, the handle 27 extends through the front of the housing 1, allowing the user to pull the handle 27 from the front, which in turn moves the mesh plate 23.

[0028] Furthermore, the protrusion rod 210 is located on the upper side of the through groove 26. The protrusion rod 210 is adapted to the through groove 26. When the protrusion rod 210 moves inside the through groove 26, it can push the grid plate 23 back and forth, causing the grid plate 23 to move back and forth, stretching or compressing the spring 211, so that the grid plate 23 can shake when the spring 211 returns to its original state.

[0029] Furthermore, the rear end of the spring 211 is fixedly connected to the inner wall of the housing 1, and the spring 211 provides power for the shaking of the grid plate 23.

[0030] Furthermore, the collection box 212 is located directly below the inclined chute 22, and the collection box 212 can collect the debris flowing down from the inclined chute 22.

[0031] Working principle: When in use, place the material on the placement plate 25, start the electric telescopic rod 28, the electric telescopic rod 28 drives the protective plate 29 to descend, the protective plate 29 drives the protrusion rod 210 through the through groove 26 and through the grid plate 23. The protective plate 29 can block the inside of the pick-up and put-out port 11 to block the pick-up and put-out port 11, prevent the debris generated during processing from flying out, and ensure the safety of the device. The debris is blocked by the box 1 and the protective plate 29, and under the guidance of the guide groove 24, it is collected in the inclined groove 22 and passes through the grid plate 23 to be collected in the collection box 212.

[0032] Start the electric telescopic rod 28, which drives the protective plate 29 to rise. The protective plate 29 drives the protrusion rod 210 to move in the through groove 26. When the protrusion rod 210 moves in the through groove 26, it will push the grid plate 23 back and forth. With the help of the spring 211, the grid plate 23 can be swayed back and forth. The debris accumulated on the top surface of the grid plate 23 will move under the action of inertia, so that the debris can pass through the grid plate 23 and keep the top surface of the grid plate 23 clean.

[0033] Furthermore, after the protrusion rod 210 is separated from the through groove 26, the handle 27 can be manually pulled to move the mesh plate 23 forward, stretching the spring 211. Then, the handle 27 is released, and the mesh plate 23 returns to its original position under the action of the spring 211, increasing the tendency of the mesh plate 23 to shake and ensuring the cleaning effect on the top surface of the mesh plate 23.
