Description

Technical Field

[0001] This invention relates to the field of forging technology, specifically to a pipe air-cooling device for forgings. Background Technology

[0002] In the forging industry, forgings still retain a significant amount of heat after the forging process. The subsequent cooling process has a crucial impact on the microstructure, performance, and dimensional accuracy of the forgings. Traditional post-forging air cooling often employs a simple method of direct fan blowing. In this method, the airflow from the fan acts directly on the surface of the forging, carrying away the heat by accelerating airflow, thus achieving a cooling effect. However, this seemingly convenient cooling method has many limitations. For example, because the airflow from the fan is not evenly distributed in space, the cooling rate varies significantly across different parts of the forging, potentially leading to large temperature differences within the forging and generating substantial thermal stress. This can cause deformation and, in severe cases, cracks, significantly affecting the dimensional accuracy and quality stability of the forging. Furthermore, relying solely on direct fan blowing makes it difficult to precisely control the cooling rate, failing to meet the production requirements of some special forgings with stringent cooling processes, thus limiting its application range and the potential for improving forging quality. Summary of the Invention

[0003] This invention provides a pipe-cooled device for forgings, which solves the problems of poor cooling uniformity and low adaptability through a modular air guide structure and adjustable connection design.

[0004] The technical solution adopted by this invention to solve its technical problem is a pipe-cooled device for forgings, including a placement platform, a fan arranged above the placement platform, an air outlet shield provided with the fan's air outlet, the air outlet shield being detachably connected to the fan, and at least two air guide pipes arranged on the air outlet shield, one end of which is fixedly connected to the air outlet shield and communicates with the inner cavity of the air outlet shield, and the other end is opposite to the placement platform; a fixed seat is arranged on the outer side of the placement platform, and a connecting rod is arranged on each air guide pipe, the end of the connecting rod away from the air guide pipe being rotatably connected to the fixed seat, and the rotation axis of the connecting rod being vertical and perpendicular to its own axis. The air guide pipe is a corrugated flexible hose, and an installation cylinder is fixedly connected to the end of the air guide pipe away from the air outlet shield, the installation cylinder being fitted onto the air guide pipe, and the connecting rod and the installation cylinder being connected by a rotating mechanism, the rotating mechanism including a rotating groove arranged at the end of the connecting rod, a rotating head arranged in the rotating groove, the rotating head being fixedly connected to the installation cylinder, and the rotation axis of the rotating head being perpendicular to the axis of the installation cylinder.

[0005] Furthermore, the outer surface of the connecting rod is provided with a threaded hole that communicates with the inner cavity of the rotating groove, and a locking screw is provided in the threaded hole.

[0006] Furthermore, each of the connecting rods is provided with a rotating seat, the rotation axis of which is perpendicular to the axis of the connecting rod. Multiple rotating seats are arranged at intervals on the top of the fixed seat and connected to the fixed seat through bearings.

[0007] Furthermore, a telescopic mechanism is provided between the connecting rod and the rotating seat.

[0008] Furthermore, an adjustment valve is provided at the end of the air duct away from the air outlet shield.

[0009] Furthermore, the placement platform has a hollow structure.

[0010] The beneficial effects of this invention are as follows: by setting an air outlet shield at the air outlet of the fan, one end of the air duct is fixedly connected to the fan shield, and the other end is opposite to the placement platform, the cold air is guided to the air duct regulating valve position through the air duct. The air volume and air speed are controlled by the regulating valve, and the cold air is delivered to the forging. Different air volumes and air speeds of cold air are delivered to different positions of the forging, which solves the problems of significant differences in the microstructure, performance and dimensional accuracy of different parts of the forging and the difficulty in accurately controlling the cooling rate in the existing air cooling method.

Detailed Implementation

[0015] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] like Figures 1-3As shown, the present invention discloses a pipe air-cooling device for forgings, comprising a placement platform 1, a fan 2 disposed above the placement platform 1, an air outlet shield 3 disposed at the air outlet of the fan 2, the air outlet shield 3 being detachably connected to the fan 2, at least two air guide pipes 4 disposed on the air outlet shield 3, one end of which is fixedly connected to the air outlet shield 3 and communicates with the inner cavity of the air outlet shield 3, and the other end is opposite to the placement platform 1; a fixing seat 5 is disposed on the outer side of the placement platform 1, and a connecting rod 6 is disposed on each air guide pipe 4, the end of the connecting rod 6 away from the air guide pipe 4 being rotatably connected to the fixing seat 5, and the rotation axis of the connecting rod 6 being vertical and perpendicular to its own axis.

[0017] The placement platform 1 is a rectangular steel platform used to place the forged parts. A fan 2 is installed 1.5-2m directly above the placement platform 1, and can be fixed to the floor of the work area using a support frame. The power of the fan 2 needs to be selected according to the size of the forging (5-10kW recommended), and the outlet diameter matches the exhaust shield 3. The exhaust shield 3 is cylindrical and is detachably connected to the outer wall of the fan 2 via a snap-fit ​​interface or by bolts. At least two high-temperature resistant corrugated flexible hoses 4 are used as air guide pipes, one end of which is sealed and fixed to the exhaust shield 3 with a flange, ensuring communication with the inner cavity of the exhaust shield 3. The length of the air guide pipes 4 is determined according to the distance between the exhaust shield 3 and the placement platform 1, preferably 2-3m. The mounting base 5 is installed on the outside of the placement platform 1 by anchor bolts. It should be noted that multiple fans 2 can be set according to the size of the placement platform 1, and each fan 2 corresponds to a mounting base 5. The connecting rod 6 can be rotatably connected to the mounting base 5 by hinge, so that the air guide duct 4 can be rotated in the horizontal plane to adjust the position of the air outlet of the air guide duct 4.

[0018] To prevent the end of the air duct 4 from swinging during air discharge, further, see... Figures 1-3 The air duct 4 is a corrugated flexible hose. An installation cylinder 7 is fixedly connected to the end of the air duct 4 furthest from the air outlet shield 3. The installation cylinder 7 is fitted onto the air duct 4. The connecting rod 6 is connected to the installation cylinder 7 via a rotating mechanism. The rotating mechanism includes a rotating groove 8 at the end of the connecting rod 6, and a rotating head 9 is disposed within the rotating groove 8. The rotating head 9 is fixedly connected to the installation cylinder 7, and the rotation axis of the rotating head 9 is perpendicular to the axis of the installation cylinder 7. The installation cylinder 7 can be bolted onto the air duct 4. The rotating groove 8 is a cylindrical cavity. The rotating head 9 includes a cylindrical platform and a rotating rod disposed within the rotating groove 8. The rotating rod and the cylindrical platform are integrally formed, fitting the rotating groove 8 at the end of the connecting rod 6 with the rotating head 9 on the installation cylinder 7. The axis of the rotating head 9 is perpendicular to the axis of the installation cylinder 7, allowing the air duct 4 to be adjusted vertically.

[0019] In the above embodiment, locking is achieved through the friction between the rotating groove 8 and the rotating head 9, which can easily lead to loosening. Further, see... Figure 3 The outer surface of the connecting rod 6 is provided with a threaded hole 10 that communicates with the inner cavity of the rotating groove 8, and a locking screw 11 is provided in the threaded hole 10. The locking screw 11 is screwed into the threaded hole 10 on the outer surface of the connecting rod 6, and the rotating head 9 is pressed against the screw by tightening the screw to fix the current air outlet angle of the air guide duct 4.

[0020] Further, see Figure 2 Each connecting rod 6 is equipped with a rotating seat 12, the rotation axis of which is perpendicular to the axis of the connecting rod 6. Multiple rotating seats 12 are spaced apart on the top of the fixed seat 5 and connected to the fixed seat 5 via bearings. Each fixed seat 5 has a rotating seat 12 mounted on its top via a bearing. This allows the connecting rod 6 to rotate more effectively in the horizontal plane. In practical use, the placement platform 1 is divided into multiple non-overlapping areas based on the number of air ducts 4, with each area corresponding to one air duct 4. This also prevents interference between the air ducts 4.

[0021] In order to adjust the relative position of the air duct 4 and the placement platform 1, further refer to... Figure 1 and Figure 2 A telescopic mechanism 13 is provided between the connecting rod 6 and the rotating seat 12. A hydraulic or threaded telescopic mechanism 13 is installed between the connecting rod 6 and the rotating seat 12, with an adjustment range of 200-500mm, to adjust the relative position of the air guide pipe 4 and the placement platform 1.

[0022] To further adjust the airflow in duct 4, see [link / reference]. Figure 1 An adjusting valve 14 is provided at the end of the air duct 4 away from the air outlet shield 3. A butterfly valve is installed at the end of each air duct 4 (near the placement platform 1), and the valve opening is controlled by a manual knob to achieve graded adjustment of air volume.

[0023] To further improve heat dissipation, see [link / reference]. Figure 1 The placement platform 1 has a hollow structure. Multiple grooves are provided on the placement platform 1 along the width direction of the placement platform 1, so that after the forging is placed on the placement platform 1, cold air can enter the grooves at the bottom of the forging to cool the bottom of the forging.

[0024] In practical use, the forging is placed on the placement platform 1. According to the shape of the forging, the thicker area of ​​the forging is determined. The rotating seat 12 is rotated and the length of the telescopic mechanism 13 is adjusted so that the outlet of the air duct 4 is opposite to the thicker area. The regulating valve 14 is used to adjust the air volume of the air duct 4 to cool the thicker area. For forgings with grooves that are not opposite to the air duct 4, the rotating head 9 can be rotated in the rotating groove 8 to make the air outlet of the air duct 4 opposite to the groove, thus avoiding heat accumulation in the groove.

[0025] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
