Description

Technical Field

[0001] The utility model relates to the technical field of forging clamps, in particular to a forging clamp dedicated to a forging machine. Background Art

[0002] A forging machine is a widely used piece of equipment in industrial production, primarily used to plastically deform metal materials to create workpieces with specific shapes and properties. During the forging process, the metal is deformed by applying tremendous pressure, thereby improving its internal structure and enhancing its strength, hardness, and toughness. Forging fixtures are tools used to secure and clamp the workpiece during the forging process.

[0003] Chinese patent publication number CN220073156U discloses a new type of special forging clamp for forging machines. The utility model uses a first telescopic rod to conveniently drive a second telescopic rod to move up and down, and uses the second telescopic rod to conveniently drive the left and right clamps to move left and right, thereby facilitating left and right clamping of forged parts of different diameters, and conveniently clamping the forged parts at different heights. It is convenient to adjust the left and right clamps at any time during the forging process, thereby facilitating the forging work.

[0004] However, the forging fixture in the above solution can only clamp workpieces of one shape, and its practicality is low. The company has to prepare multiple different types of fixtures, which increases the company's cost in fixture selection. At the same time, frequent replacement of fixtures will also reduce production efficiency. The forging machine will generate a lot of heat during the processing process. When the fixture clamps the workpiece, due to the lack of effective heat dissipation measures, heat will accumulate between the workpiece and the fixture, resulting in the workpiece being unable to dissipate heat in time, increasing the risk of workpiece deformation and cracking, reducing product quality, and may also lead to an increase in scrap rate, increasing the company's production costs.

[0005] Therefore, it is necessary to invent a special forging fixture for a forging machine. Utility Model Content

The liquid inlet hose 171 and the liquid outlet hose 2 173 themselves are curved and extensible, which is convenient for following the slider 16 to move back and forth to prevent it from breaking when stretched.

[0024] Furthermore, a short tube 1713 is provided at the other end of the Z-shaped tube 1712 , and the short tube 1713 is connected to the semi-annular tube 1714 .

[0025] Furthermore, symmetrically distributed rectangular grooves 131 are provided on both sides of the hollow box 13 , and the slider 16 is slidably installed in the rectangular grooves 131 , which facilitates the sliding of the slider 16 .

[0026] Furthermore, a motor 14 is fixedly provided on one side of the hollow box 13, and the output shaft of the motor 14 passes through the hollow box 13 and is fixedly connected to the double-headed threaded rod 15, so as to facilitate the rotation of the double-headed threaded rod 15. The double-headed threaded rod 15 has opposite threaded grooves at both ends, so as to facilitate the sliders 16 on both sides to move toward or away from each other.

[0027] Furthermore, a motor 18 is fixedly provided in the rectangular frame 1, and the output shaft of the motor 18 passes through the rectangular frame 1 and is fixedly connected to the base plate 11, so as to facilitate the rotation of the base plate 11, thereby driving the clamped workpiece to rotate horizontally, facilitating subsequent processing and improving processing efficiency.

[0030] Working principle: When using this solution, the clamping plate 161 or the clamping ring 163 can be selected according to the shape of the workpiece. When a rectangular workpiece needs to be clamped, the workpiece can be placed between the clamping plates 161 on both sides, and then the motor 14 is started. The motor 14 drives the double-headed threaded rod 15 to rotate, and then drives the sliders 16 on both sides and the clamping plates 161 on both sides to move toward each other, thereby achieving clamping of the rectangular workpiece. When a cylindrical workpiece needs to be clamped, the cylindrical workpiece can be placed between the clamping rings 163 on both sides, and then the motor 14 is started. The motor 14 drives the double-headed threaded rod 15 to rotate, and then drives the sliders 16 on both sides and the clamping rings 163 on both sides to move toward each other, thereby achieving clamping of the cylindrical workpiece. Regardless of whether it is a rectangular workpiece or a cylindrical workpiece, a suitable clamping tool can evenly distribute the force on the workpiece when it is subjected to force, avoid deformation caused by local uneven force, and further ensure the processing quality;

[0031] During the processing, the cooling device 17 plays an important role (the cooling device 17 is a cooling water circulator, model Wuxi Guanya FL-1000. The high-temperature and high-pressure refrigerant gas compressed by the compressor enters the condenser and exchanges heat with the cooling water to be condensed into a medium-temperature and high-pressure liquid. After drying and filtering, it flows through the thermal expansion valve and is throttled and reduced in pressure to a low-temperature and low-pressure liquid. It enters the evaporator, absorbs the heat of the water, and evaporates into a low-temperature and low-pressure gas. It is sucked into the compressor and then compressed to enter the next refrigeration cycle. The cooled cold water is transported to the terminal equipment through the water pump, and this cycle is repeated to achieve cooling and cooling.) The coolant passes through the cooling device 1 7 enters the liquid inlet pipe 171 and flows into the connecting pipe 1711 in the clamping plate 161, then passes through the Z-shaped pipe 1712, and finally reaches the semi-annular pipe 1714, and finally flows into the cooling device 17 through the second liquid outlet hose 173. Regardless of whether the clamping plate 161 is used to clamp the rectangular workpiece or the clamping ring 163 is used to clamp the cylindrical workpiece, the coolant can circulate back and forth in this path. This circulating coolant can easily take away the heat generated by the workpiece during the processing, so that the workpiece can effectively dissipate heat, ensuring the smooth progress of the processing, while also helping to maintain the performance and quality of the workpiece and extend the service life of the processing tools.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
