Description

Technical Field

[0001] This utility model belongs to the technical field of die forging hydraulic press, and in particular relates to a die blowing, cooling and lubrication device for die forging hydraulic press. Background Technology

[0002] A die forging hydraulic press is a large-scale pressure equipment used for metal die forging. It is primarily used to forge metal billets within a die under high pressure and temperature. A high-pressure oil pump forces hydraulic oil into the working cylinder, pushing the piston and slide downwards, applying enormous pressure (typically thousands to tens of thousands of tons) to plastically deform the metal billet within the die cavity, shaping it into parts of a specific shape and size. It is widely used in aerospace, automotive manufacturing, and machining industries, and is an indispensable key piece of equipment in modern manufacturing.

[0003] During continuous operation, the die of a forging hydraulic press comes into contact with the high-temperature metal billet. The high pressure and friction generate a large amount of heat, causing the die to expand and deform, thus affecting its dimensional accuracy. Therefore, cooling the die is necessary. Furthermore, after each operation, debris accumulates on the die, requiring timely cleaning. Before starting the next operation, lubricant needs to be sprayed onto the die.

[0004] Currently, there are still some problems with the integrated blowing, cooling and lubrication device of large-scale die forging hydraulic presses in China: 1. Insufficient cooling efficiency due to unreasonable layout of cooling channels; 2. Unsatisfactory blowing effect due to unreasonable layout of blowing channels; 3. Uneven distribution of lubricant due to unreasonable layout of lubrication channels.

[0005] Therefore, based on these issues, it is of great practical significance to develop a new type of purging cooling and lubrication device. Utility Model Content

This device can reduce wear and fatigue on the mold surface, ensure consistent product quality, effectively and efficiently solve the problems of mold blowing, cooling, and lubrication, improve work efficiency, and extend the service life of the mold.

[0007] This utility model is implemented as follows: a mold blowing cooling and lubrication device for a forging hydraulic press includes a nozzle, a bracket, a hydraulic cylinder and a guide column. The nozzle is installed on the bracket and located above the bracket. The hydraulic cylinder is fixed to the centering device by a fixed support. The telescopic end of the hydraulic cylinder is connected to the bracket by a pin. The guide column is fixed to the centering device by a trunnion support. One end of the guide column is fixedly installed on the bracket.

[0008] The nozzle has a circular structure and includes at least one liquid pipe and at least one gas pipe arranged concentrically. The liquid pipe and the gas pipe correspond one-to-one. When there are multiple liquid pipes and multiple gas pipes, the liquid pipes are connected to each other and the gas pipes are connected to each other. Multiple liquid pipe nozzles are evenly arranged on both sides of each liquid pipe, and multiple gas pipe nozzles are evenly arranged on both sides of each gas pipe.

[0023] Please see Figures 1-3 An embodiment of this utility model provides a mold blowing cooling and lubrication device for a forging hydraulic press, including a nozzle 1, a bracket 2, a hydraulic cylinder 5, and a guide post 6. The nozzle 1 is mounted on the bracket 2 and located above the bracket 2. The hydraulic cylinder 5 is fixed to the centering device through a fixed support 7. The telescopic end of the hydraulic cylinder 5 is connected to the bracket 2 through a pin 3. The guide post 6 is fixed to the centering device through a trunnion support 8, and one end of the guide post 6 is fixedly mounted on the bracket 2.

[0024] The nozzle 1 is bolted to the bracket 2, which is a simple and reliable connection method that is easy to install and disassemble. The hydraulic cylinder 5 not only plays a driving role, but also provides some support for the bracket 2, which improves the reliability of the device. The guide column 6 plays a guiding role in the device, providing a stable support for the nozzle 1 and the bracket 2, and bearing the various forces generated by the nozzle 1 during operation, ensuring that the entire device will not shake or deviate during operation.

[0025] The nozzle 1 has a circular structure and includes at least one liquid pipe 1-1 and at least one gas pipe 1-2 arranged concentrically. The liquid pipes 1-1 and gas pipes 1-2 correspond one-to-one. When there are multiple liquid pipes 1-1 and multiple gas pipes 1-2, the liquid pipes 1-1 are interconnected, and the gas pipes 1-2 are interconnected. Multiple liquid nozzles 1-3 are evenly arranged on both sides of each liquid pipe 1-1, and multiple gas nozzles 1-4 are evenly arranged on both sides of each gas pipe 1-2. In this embodiment, two liquid pipes 1-1 and two gas pipes 1-2 are provided, and the two liquid pipes 1-1 are interconnected, and the two gas pipes 1-2 are interconnected.

[0026] The annular nozzle 1 can cover the entire surface or most of the mold; the evenly arranged multiple liquid nozzles 1-3 allow cooling water and lubricant to be sprayed evenly onto the mold surface, effectively preventing local overheating of the mold, reducing thermal stress and thermal deformation, thereby extending the service life of the mold, improving the quality and precision of the forgings, effectively reducing friction between the mold and the metal billet, reducing mold wear, facilitating the flow of the metal billet in the mold cavity, making the forging process smoother, and reducing defects and cracks on the surface of the forgings; the evenly arranged multiple air nozzles 1-4 can generate annular airflow, which can more effectively remove metal chips, dust and other impurities from the mold surface, preventing impurities from remaining in the mold cavity, thereby reducing defects on the surface of the forgings and improving the surface quality and dimensional accuracy of the forgings.

[0027] In a preferred embodiment, each pair of corresponding liquid lines 1-1 and gas lines 1-2 are connected together, and adjacent pairs are connected by reinforcing ribs 1-5. This significantly enhances the structural strength of the entire nozzle 1, thereby improving the safety and reliability of the entire device.

[0028] In a preferred embodiment, one end of the guide post 6 is connected and fixed to the bracket 2 via a pressure block 4. The use of the pressure block 4 makes installation and disassembly quick and convenient. The pressure block 4 applies sufficient clamping force through bolts and other fasteners to ensure a firm and reliable connection between the guide post 6 and the bracket 2, thereby guaranteeing the stability of the nozzle 1 during operation.

[0029] In a preferred embodiment, at least two guide posts 6 are provided and symmetrically arranged on both sides of the hydraulic cylinder 5 to further ensure the stability of the nozzle 1 during operation.

[0030] In a preferred embodiment, the nozzle 1 is provided with a base 1-6 at its bottom, and the nozzle 1 is mounted on the bracket 2 via the base 1-6 and bolts, ensuring the reliability of the nozzle 1 installation and the stability of its operation.

[0031] The specific working process of this utility model is as follows:

[0032] This device is installed on top of the centering device, which ensures that the extension and retraction of the hydraulic cylinder 5 is aligned with the centerline of the mold. It is driven by the hydraulic cylinder 5 and guided by the guide pillar 6. During breaks in the hydraulic press's operation, the hydraulic cylinder 5 pushes the nozzle 1 to the center position of the mold, first spraying compressed air. The pressurized air then blows through the air path nozzles 1-4 to clean the mold. Next, cooling water is sprayed to cool the mold, and then the cooling water is blown away. Finally, liquid graphite mixture is sprayed to lubricate the mold. The cooling water and lubricant are sprayed onto the mold through the liquid path nozzles 1-3 for cooling and lubrication. This device has a simple structure but effectively and efficiently solves the problems of mold blowing, cooling, and lubrication, improving work efficiency.

[0033] The structure of this utility model is relatively simple. The liquid pipeline 1-1 and the gas pipeline 1-2 are integrated into a circular nozzle 1, which is compact and occupies little space. The connection method between each component is clear, which facilitates maintenance personnel to inspect and repair. It optimizes the cooling, purging and lubrication effect, reduces the thermal deformation of the mold, the residue of impurities on the mold surface and the wear of the mold, improves the efficiency of cooling, purging and lubrication, reduces energy consumption, extends the service life of the mold, and improves the quality and precision of the forgings.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
