Description

Technical Field

[0001] The utility model mainly relates to the technical field of forging processing, in particular to a material turning device for forging heating. Background Art

[0002] The hydraulic piping process follows: raw material inspection - billet cutting - forging billet heating - die forging - quenching - shot blasting - automated CNC machining - deburring - electrolysis and electroplating - final inspection - and storage. The billet heating process involves electrically heating the billet to a temperature of 880-950°C, depending on product requirements, to achieve uniform austenitization. Turning the billet during heating ensures uniform heating. Uneven heating can lead to problems such as overheating, burning, and internal cracks in the billet.

[0003] At present, the patent with the authorization announcement number CN 213052605 U discloses a forging heating furnace turning device. The device is provided with arc grooves arranged in a sequence of gradually lower positions in the heating furnace. The middle part of the arc groove is hinged and provided with an ejector rod that passes through the bottom of the heating furnace. When the blank needs to be turned over, the ejector rod is driven to move upward, pushing one side of the arc groove upward for a certain distance. The blank rolls into the next arc groove by gravity, realizing the blank turning over. After multiple turning over, the entire surface of the blank can be heated evenly. However, existing devices such as the above-mentioned device have the following problems: more or less, it is necessary to install a component that can move in the heating furnace to drive the blank turning. The heating temperature in the heating furnace is high, and the heat resistance of the components in the furnace is required to be high, which makes it difficult to install the movable component and its driving mechanism. If the driving mechanism is placed outside the heating furnace, it is necessary to open the furnace wall to connect the movable component and its driving mechanism, which will cause the problem of high-temperature gas overflow in the heating furnace. Utility Model Content

[0004] The technical solution of the present utility model is aimed at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. It mainly provides a turning device for forging heating, which is used to solve the technical problem raised in the above background technology that the setting requirements of the existing movable turning mechanism in the furnace are high and it will cause the overflow of high-temperature gas in the heating furnace.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A material turning device for forging heating includes a heating furnace; an arc-shaped support frame for holding blanks is provided in the heating furnace, and the arc-shaped support frame is arranged to gradually lower from its two sides to the middle; an arc-shaped support is provided at the bottom outside the heating furnace, and the arc-shaped support is arranged to gradually lower from its two sides to the middle; a driving mechanism is provided on the arc-shaped support for driving the heating furnace to move back and forth along the curvature of the arc-shaped support.

[0007] Furthermore, the arc-shaped support frame includes two arc-shaped plates arranged in parallel, a connecting plate connected to the ends between the two arc-shaped plates, and rollers arranged at equal intervals between the two arc-shaped plates.

[0008] Furthermore, an arc-shaped slide groove is provided on the upper arc surface of the arc-shaped support along its arc, and a roller located in the arc-shaped slide groove is installed at the bottom of the heating furnace.

[0009] Furthermore, a side vertical plate is fixed on the side where the arc end surface of the arc support is located, and an arc limit groove is provided on the side vertical plate and is arranged coaxially with the arc support, and a limit plate extending into the arc limit groove is fixed on the heating furnace, and the limit plate can move along the arc limit groove.

[0010] Furthermore, the driving mechanism includes two groups of cams and their driving components respectively arranged on both sides of the arc support, and the two groups of cams and their driving components are respectively located on two opposite sides of the heating furnace, and the movement states of the cams on both sides of the heating furnace are opposite.

[0011] Furthermore, the driving assembly includes a rotating shaft fixedly connected to the cam, and a motor for driving the rotating shaft to rotate.

During this process, the arc-shaped support frame moves accordingly, and both the arc-shaped support frame and the heating furnace tilt back and forth, thereby causing the blank to roll back and forth on the arc-shaped support frame, thereby achieving material turning. Furthermore, the present invention only has an arc-shaped support frame installed in the heating furnace, and the arc-shaped support frame remains stably located in the heating furnace and does not need to be moved, significantly reducing the difficulty of installation. Only the heat-resistant treatment of the arc-shaped support frame is required. The arc-shaped support and the driving mechanism are both installed outside the heating furnace and operate outside the heating furnace, without the need to open the furnace wall. The problem of high-temperature gas overflowing from the heating furnace will not occur during the material turning process.

[0015] The driving mechanism of the utility model adopts two sets of cam mechanisms to act on two opposite sides of the heating furnace respectively, and the movement states of the cams on both sides are opposite.

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly used by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] Example 1: Please refer to the attached Figure 1 and attached Figure 3 A turning device for forging heating includes a heating furnace 1, the longer direction of which is the longitudinal direction, and the furnace door is arranged on the end face in the width direction. An overhead arc-shaped support frame 2 for holding the blank is provided in the heating furnace 1. The arc-shaped support frame 2 is arranged gradually lower from both sides to the middle, and the arc direction of the arc-shaped support frame 2 is located in the width direction of the heating furnace 1; the arc-shaped support frame 2 is made of an arc-shaped plate, and through holes are evenly opened on it to improve the heating effect of the bottom of the blank;

[0029] Please refer to the attached Figure 1 -Attached Figure 4 The outer bottom of the heating furnace 1 is provided with an arc-shaped support 3, which is gradually lowered from both sides to the middle. The arc direction of the arc support 3 is located in the width direction of the heating furnace 1. The arc support 3 is provided with a driving mechanism 4 for driving the heating furnace 1 to reciprocate along the arc of the arc support 3;

[0030] In this embodiment, please refer to the attached Figure 1 -Attached Figure 4 The drive mechanism 4 includes two sets of cams 41 and their drive assemblies, respectively, located on opposite sides of the arcuate support 3. The two sets of cams 41 and their drive assemblies are located on opposite sides of the heating furnace 1. The cams 41 on either side of the heating furnace 1 move in opposite directions (when the small-diameter end of the cam 41 on one side contacts the heating furnace 1, the large-diameter end of the cam 41 on the other side contacts the heating furnace 1). The drive assembly includes a rotating shaft 42 fixedly connected to the cam 41 and a motor 43 for driving the rotating shaft 42. The rotating shaft 42 is arranged parallel to the heating furnace 1. Both ends of the rotating shaft 42 are rotatably connected to mounting plates 44 fixedly connected to the arcuate support 3. The motor 43 is connected to one end of the rotating shaft 42. In the initial state, the heating furnace 1 is stably positioned in the upper center of the arcuate support 3, and the contact points between the large-diameter and small-diameter ends of the cams 41 on both sides of the heating furnace 1 are located between the large-diameter and small-diameter ends.

[0031] The working principle of the above-mentioned turning device for forging heating is as follows: after the hydraulic pipe blank is placed in the heating furnace 1, the furnace door is closed and the heating treatment is started; during the heating process, the motors 43 on both sides are started to drive the rotating shafts 42 on both sides to rotate synchronously, and the cams 41 on both sides rotate accordingly, and the cam 41 on one side rotates toward the large diameter end, pushing the heating furnace 1 to move along the arc support 3 until it rotates to the large diameter end. At this time, the cam 41 on the other side just rotates to the small diameter end; then, the cam 41 on the other side rotates from the small diameter end to the large diameter end, pushing the heating furnace 1 to move in the opposite direction until it rotates to the large diameter end, so that the continuous rotation of the cams 41 on both sides can push the heating furnace 1 to move back and forth along the curvature of the arc support 3. In this process, the arc support frame 2 moves accordingly, and the arc support frame 2 and the heating furnace 1 will tilt back and forth, which can prompt the blank to roll back and forth on the arc support frame 2 to achieve turning.

[0032] From the above content, it can be seen that the present invention only provides an arc-shaped support frame 2 in the heating furnace 1, and the arc-shaped support frame 2 remains stable in the heating furnace 1 and does not need to move; the arc-shaped support 3 and the driving mechanism 4 are both provided on the outside of the heating furnace 1, and operate on the outside of the heating furnace 1, without opening the furnace wall of the heating furnace 1, and the problem of high-temperature gas overflow in the heating furnace 1 will not occur during the turning process.

[0033] Example 2: This example differs from Example 1 in that:

[0034] In this embodiment, please refer to the attached Figure 3 and attached Figure 5 The arc-shaped support frame 2 comprises two parallel arc-shaped plates 21, a connecting plate 22 connected at the ends between the two arc-shaped plates 21, and rollers 23 arranged at equal intervals between the two arc-shaped plates 21. The rollers 23 are rotatably connected to the arc-shaped plates 21. During use, the rollers 23 are parallel to the blank. The equally spaced rollers 23 have a corrugated surface on their upper sides, which promotes the tumbling of the blank. Furthermore, the rotatable rollers 23 enhance the driving force for the movement of the blank.

[0035] Other aspects are the same as those of the first embodiment.

[0036] Example 3: This example differs from Example 2 in that:

[0037] In this embodiment, please refer to the attached Figure 5 The upper curved surface of the arc support 3 is provided with an arc chute 31 along its curvature, and the bottom of the heating furnace 1 is provided with a roller 5 located in the arc chute 31. The limiting guide effect between the roller 5 and the arc chute 31 can guide the movement of the heating furnace 1 and prevent the heating furnace 1 from deviating.

[0038] In this embodiment, please refer to the attached Figure 2 -Attached Figure 5 A side plate 6 is fixed to the side of the arc-shaped support 3 where the arc-shaped end surface is located. The side plate 6 is provided with an arc-shaped limiting groove 61 coaxially arranged with the arc-shaped support 3. A limiting plate 7 is fixed to the heating furnace 1, extending into the arc-shaped limiting groove 61. The limiting plate 7 can move along the arc-shaped limiting groove 61. The limiting action between the limiting plate 7 and the arc-shaped limiting groove 61 prevents the heating furnace 1 from moving upward, thereby preventing the roller 5 from jumping off the arc-shaped chute 31, further ensuring the guiding effect on the movement of the heating furnace 1.

[0039] In this embodiment, please refer to the attached Figure 3 -Attached Figure 4 The middle part of the lower arc surface of the arc-shaped support 3 contacts the ground, and both ends of the lower arc surface of the arc-shaped support 3 are connected to support plates 8 supported on the ground, which can provide a more stable support effect, and the support plate 8 can be more easily fixed to the ground.

[0040] Other aspects are the same as those of the second embodiment.

[0041] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
