Description

Technical Field

[0001] This utility model belongs to the field of flange processing technology, and in particular relates to a press for flange processing. Background Technology

[0002] A flange, also called a flange plate or flange, is a component used to connect pipes to each other, attached to the pipe ends. Flanges have holes, and bolts are used to tightly connect two flanges. A gasket is used for sealing between flanges. A flange is a disc-shaped component, most commonly found in piping engineering, and flanges are always used in pairs. In piping engineering, flanges are mainly used for connecting pipes. Flange manufacturing processes are divided into casting and forging. Die forging is widely used because it produces flanges with a dense structure and good mechanical properties. When forging flanges, a press is usually used to forge the flange.

[0003] A search revealed a flange processing press with application number 202322768586.3. The press comprises a main body, including an operating table. A vertical plate is vertically fixed to the upper surface of the operating table, and a vertical groove is vertically formed inside the vertical plate. A pushing component, including a slider, is installed inside the groove. A first rack is fixedly connected to the rear side wall of the slider. A rotating shaft is horizontally rotatably connected inside the vertical plate. A first gear is fixedly connected to the rear end of the rotating shaft, and a first wheel is fixedly connected to the front end of the rotating shaft. A support is fixedly connected to the upper surface of the operating table. This utility model allows the processed flange to be pushed out from directly below the forging head by a pusher plate when the forging head rises after forging. This avoids the need for operators to manually remove the flange, which could lead to accidental pinching and injury, thus improving safety.

[0004] However, in the above-mentioned method, during the flange forging process, the flange needs to be forged at a high temperature. The forging head will continuously heat up due to friction and heat transfer. If this heat cannot be dissipated in time, the surface of the forging head will easily wear and deform, which will affect its accuracy and service life. Therefore, it is necessary to provide a new type of press for flange processing to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a flange processing press, which aims to solve the problem mentioned in the background art that the existing flange processing press lacks effective cooling of the forging head, resulting in easy wear and deformation of the forging head during use.

[0006] To solve the above problems, this utility model is implemented as follows: a flange processing press includes: an operating table, on the top of which a housing is fixedly installed; a discharge port for discharging debris is provided on the operating table, and a wire mesh is fixedly installed on the inner wall of the discharge port; a hydraulic cylinder is fixedly installed on the inner wall of the top of the housing, and a forging head for forging flanges is fixedly installed on the output rod of the hydraulic cylinder, and a heat-conducting pipe is provided on the forging head; a water tank is fixedly installed on one side of the housing; a liquid conveying mechanism installed on the housing for cooling the forging head; and a pushing mechanism assembled on the housing for pushing out the flange.

[0007] Preferably, the liquid delivery mechanism includes: a water pump fixedly installed on the inner wall of one side of the housing, a water pump with a water pump pipe fixedly installed on the water pump's pumping end, one end of the water pump pipe extending into the interior of the water tank; a first flexible hose fixedly installed on the water pump's draining end, one end of the first flexible hose being fixedly connected to one end of the heat-conducting pipe; a connecting pipe fixedly installed on the housing, one end of the connecting pipe extending into the interior of the water tank; and a second flexible hose fixedly installed on the heat-conducting pipe, one end of the second flexible hose being fixedly connected to one end of the connecting pipe.

[0008] Preferably, the pushing mechanism includes: a housing fixedly mounted on the housing, a screw rotatably mounted on the housing; a rectangular tube threaded onto the screw, the rectangular tube being slidably connected to the inner wall of the housing; a motor disposed on one side of the housing, the output shaft of the motor being fixedly connected to one end of the screw; and a push plate fixedly mounted on the rectangular tube, the bottom of the push plate contacting the top of the operating table.

[0009] Preferably, two springs are fixedly installed on the top inner wall of the housing, and the bottom ends of the two springs are fixedly connected to the first hose and the second hose, respectively.

[0010] Preferably, a protective cover is fixedly installed on one side of the housing, and the inner wall of the protective cover is fixedly connected to the motor.

[0013] Compared with related technologies, the flange processing press provided by this utility model has the following advantages:

[0014] Compared with existing technologies, the flange processing press provided in this solution can drive the forging head to move vertically through a hydraulic cylinder, allowing the forging head to forge flanges placed on the operating table. Through the use of a liquid conveying mechanism, water from the water tank is continuously transported to the heat pipes. This water eventually returns to the water tank, allowing the heat pipes to use the low temperature of the water to remove heat from the forging head, thus cooling it down in a timely manner. This makes the forging head less prone to wear and deformation, greatly improving its durability and performance. The pushing mechanism can push the forged flange out from under the forging head, avoiding the safety risks that may arise from manual material handling. It also smoothly pushes the debris and waste generated during the forging process to the discharge port, allowing them to pass through the mesh of the wire mesh and fall into the collection box below, making collection convenient and preventing debris and waste from falling to the ground.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a press for flange processing, such as Figure 1-4 As shown, the flange processing press includes: an operating table 1, a housing 2 fixedly mounted on the top of the operating table 1, a discharge port for discharging debris on the operating table 1, and a wire mesh 12 fixedly mounted on the inner wall of the discharge port; a hydraulic cylinder 3 fixedly mounted on the inner wall of the top of the housing 2, a forging head 4 for forging flanges fixedly mounted on the output rod of the hydraulic cylinder 3, and a heat-conducting pipe 5 provided on the forging head 4; a water tank 6 fixedly mounted on one side of the housing 2; a liquid conveying mechanism mounted on the housing 2 for cooling the forging head 4; and a pushing mechanism mounted on the housing 2 for pushing out the flange.

[0023] In this embodiment, when using this press to forge a flange, the flange to be forged is first placed under the forging head 4. Then, the hydraulic cylinder 3 is activated to drive the forging head 4 to move vertically, allowing the forging head 4 to forge the flange below under pressure. After forging, a pushing mechanism can be used to push the forged flange out from under the forging head 4, avoiding the safety risks that may be caused by manual material handling. The pushing mechanism also smoothly pushes the debris and waste generated during the forging process to the discharge port. Debris and waste can pass through the mesh of wire mesh 12 and fall into the collection box below, making collection convenient. Throughout the forging process, the liquid conveying mechanism needs to be continuously activated. The liquid conveying mechanism will continuously transport water from the water tank 6 to the heat pipe 5. Finally, the water that enters the heat pipe 5 will return to the water tank 6. In this way, the heat pipe 5 can use the low temperature of the water to remove the heat from the forging head 4, which can cool the forging head 4 in time, making the forging head 4 less prone to wear and deformation, greatly improving its durability, and resulting in better performance.

[0024] In a further preferred embodiment of the present invention, the liquid delivery mechanism includes: a water pump 7 fixedly installed on the inner wall of one side of the housing 2, a water pump pipe 8 fixedly installed on the water pump 7's pumping end, one end of the water pump pipe 8 extending into the interior of the water tank 6; a first flexible hose 9 fixedly installed on the water pump 7's draining end, one end of the first flexible hose 9 being fixedly connected to one end of the heat-conducting pipe 5; a connecting pipe 10 fixedly installed on the housing 2, one end of the connecting pipe 10 extending into the interior of the water tank 6; and a second flexible hose 11 fixedly installed on the heat-conducting pipe 5, one end of the second flexible hose 11 being fixedly connected to one end of the connecting pipe 10.

[0025] In this embodiment, the liquid delivery mechanism is used to cool the forging head 4. When in use, the water pump 7 is started, and the water pump 7 will transfer the water in the water tank 6 to the first hose 9 through the water pumping pipe 8. The first hose 9 will transfer the water to the heat conduction pipe 5, so that the heat conduction pipe 5 can use the low temperature of the water to remove the temperature of the forging head 4, so that the temperature of the forging head 4 can be dissipated in time, making the forging head 4 less prone to wear and deformation during use. Finally, the water that enters the heat conduction pipe 5 will enter the connecting pipe 10 through the second hose 11, and finally be discharged into the water tank 6, so that the water can be recycled.

[0026] In a further preferred embodiment of this utility model, the pushing mechanism includes: a housing 13 fixedly mounted on the housing 2, with a screw 14 rotatably mounted on the housing 13; a rectangular tube 15 threadedly mounted on the screw 14, the rectangular tube 15 being slidably connected to the inner wall of the housing 13; a motor 16 disposed on one side of the housing 13, the output shaft of the motor 16 being fixedly connected to one end of the screw 14; and a push plate 17 fixedly mounted on the rectangular tube 15, the bottom of the push plate 17 being in contact with the top of the operating table 1.

[0027] In this embodiment, the pushing mechanism is used to push out the flange. When it is necessary to push out the forged flange, the motor 16 is started. The motor 16 drives the screw 14 to rotate. The screw 14 drives the rectangular tube 15 to slide in the housing 13, so that the rectangular tube 15 drives the push plate 17 to move. In this way, the push plate 17 can push out the forged flange from below the forging head 4, which can avoid the safety risks that may be caused by manual material handling. At the same time, it can also push the debris and waste generated during the forging process to the discharge port smoothly, so that the debris and waste can pass through the mesh of the wire mesh 12 and fall into the collection box below, which is more convenient for collection.

[0028] In a further preferred embodiment of the present invention, two springs 18 are fixedly installed on the top inner wall of the housing 2, and the bottom ends of the two springs 18 are fixedly connected to the first hose 9 and the second hose 11, respectively.

[0029] In this embodiment, the use of two springs 18 can effectively lift the first hose 9 and the second hose 11, thereby preventing them from interfering with or hindering the normal use of the forging head 4 due to their excessive length.

[0030] In a further preferred embodiment of the present invention, a protective cover is fixedly installed on one side of the housing 13, and the inner wall of the protective cover is fixedly connected to the motor 16.

[0031] In this embodiment, the use of the protective cover not only allows the motor 16 to be stably installed on one side of the housing 13, but also provides dust and water protection for the motor 16.

[0032] In a further preferred embodiment of this utility model, a plurality of support legs are fixedly installed at the bottom of the operating table 1, and a collection box is provided below the discharge port.

[0033] In this embodiment, the use of a collection box enables the collection of debris and waste falling from the discharge port, preventing debris and waste from falling onto the ground.

[0034] In a further preferred embodiment of this utility model, a water inlet pipe is fixedly installed on the top of the water tank 6, and a drain pipe is fixedly installed on one side of the water tank 6, with a valve provided on the drain pipe.

[0035] In this embodiment, water can be added to the inside of the water tank 6 through the water inlet pipe, and the water in the water tank 6 can be discharged conveniently by the use of the drain pipe and valve.

[0036] In summary, compared with related technologies, this solution uses hydraulic cylinder 3 to drive the forging head 4 to move vertically, allowing the forging head 4 to forge the flange placed on the operating table 1. Through the use of a liquid conveying mechanism, water from the water tank 6 is continuously transported to the heat pipe 5. This water eventually returns to the water tank 6, allowing the heat pipe 5 to use the low temperature of the water to remove heat from the forging head 4, thus cooling the forging head 4 in a timely manner. This makes the forging head 4 less prone to wear and deformation, greatly improving its durability and performance. The pushing mechanism allows the forged flange to be pushed out from under the forging head 4, avoiding the safety risks that may result from manual material handling. It also smoothly pushes the debris and waste generated during the forging process to the discharge port, allowing them to pass through the mesh of the wire mesh 12 and fall into the collection box below, making collection convenient and preventing debris and waste from falling to the ground.

[0037] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
