Description

Technical Field

[0001] The present invention relates to the technical field of forging cooling, and particularly relates to a processing device for preventing the cooling deformation of titanium ring forgings after forging. Background Art

[0002] Titanium alloy refers to a variety of alloy metals made of titanium and other metals. Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance, and high heat resistance. Titanium rings forged from titanium alloys are widely used in industries such as vacuum salt production, fine chemical industry, petrochemical industry, pharmaceuticals, chlor-alkali industry, electroplating, electrolysis, aerospace, and seawater desalination.

[0003] Poor thermal conductivity is a significant characteristic of titanium alloys. The poor thermal conductivity causes the surface of the titanium alloy billet to cool faster than the inside after being heated and taken out of the furnace. If the operation is improper, a relatively large temperature difference will be caused inside and outside the billet, exacerbating the uneven deformation inside and outside the billet during the forging deformation process of titanium alloys, and even cracking, which will seriously affect the service life and reliability of titanium alloy forgings. Therefore, after the titanium ring forging is completed, it is generally cooled by natural cooling. However, under the condition of natural cooling, due to the poor thermal conductivity of the titanium ring itself, the surface of the titanium ring dissipates heat faster than the inside of the titanium ring, resulting in a large temperature difference between the inside and outside, ultimately affecting the quality of the semi-finished titanium ring, leading to dimensional deformation. And because titanium has a very strong affinity with oxygen at high temperatures, oxygen continuously diffuses into the titanium matrix, and an excessive amount of oxygen elements form a hard and brittle layer inside the matrix. When the titanium ring forging is exposed to air for a long time and cooled naturally, cracks are likely to occur during the cooling process. Summary of the Invention

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0029] Example 1

[0030] A processing device for preventing the cooling deformation of titanium ring forgings after forging, as Figures 1 - 5 shown, includes an installation main body 1, a constant temperature box 2, an installation column 3, a heating resistor 4, an annular support cylinder 5, a temperature control module 6 and a heat dissipation cover 7. Two constant temperature boxes 2 are symmetrically installed on the top of the installation main body 1. The installation column 3 is welded inside the installation main body 1. A through hole is opened on the top of the installation main body 1. A heating cavity is provided in the middle of the constant temperature box 2. The diameter of the heating cavity is the same as that of the through hole and they are connected. The heating resistor 4 is fixed on the top of the installation column 3 by bolts. The heating resistor 4 passes through the through hole and is placed in the heating cavity of the constant temperature box 2. The annular support cylinder 5 is placed on the installation column 3 and is located in the gap between the heating resistor 4 and the inner wall of the heating cavity, and is in close contact with the outer side wall of the heating resistor 4 and the inner side wall of the heating cavity. The temperature control module 6 is installed on the outer side wall of the installation main body 1 by bolts. The temperature control module 6 is electrically connected to the heating resistor 4 and the constant temperature box 2 respectively. The temperature control module 6 is used to adjust the heating power of the heating resistor 4 and the constant temperature box 2. The heat dissipation cover 7 is spirally installed on the outer side wall of the constant temperature box 2.

[0031] As Figure 6 shown, it also includes a covering cover 8. The covering cover 8 is placed on the top of the constant temperature box 2, and the covering cover 8 and the constant temperature box 2 are in contact with each other.

[0032] Before using this device, preheating is required. The temperature of the heating resistor 4 and the constant temperature box 2 is adjusted through the temperature control module 6 for preheating. The preheating temperature shall not exceed the forging temperature of the titanium ring. The preheating temperature is preferably 10% lower than the forging temperature. Subsequently, the forged titanium ring forging is placed in the gap between the heating cavity and the heating resistor 4, and then the covering cover 8 is covered. The purpose is to make the titanium ring forging cool in a micro-oxygen environment to avoid damage caused by contact in a multi-oxygen environment. After the covering cover 8 is covered, the power supply of the constant temperature box 2 and the heating resistor 4 is cut off, continuous heating is turned off, and the heat dissipation cover 7 on the constant temperature box 2 is opened to enable the forged titanium ring to cool synchronously with the natural cooling of the heating resistor 4 and the constant temperature box 2. Under this condition, the external temperature of the titanium ring forging is kept stable by the heating resistor 4 and the constant temperature box 2, and the internal and external temperature difference of the titanium ring forging is basically the same during the natural cooling process, so as to avoid the situation of cooling deformation damage of the titanium ring forging. After the titanium ring forging is cooled, the annular support cylinder 5 can be pushed to eject and take away the titanium ring forging, and thus the cooling of the titanium ring forging is completed.

[0033] Example 2

[0034] On the basis of Example 1, as Figure 3 , Figure 7As shown in the figure, it further includes a lifting component 9, and the lifting component 9 is arranged at the bottom inside the installation main body 1; the lifting component 9 includes a guide rod 91, a ring sleeve 92 and an electric push rod 93. The guide rod 91 is welded to the bottom inside the installation main body 1, and the ring sleeve 92 is slidably connected to the guide rod 91. The ring sleeve 92 is welded to the outer side wall of the annular support cylinder 5. The electric push rod 93 is installed at the bottom inside the installation main body 1 by bolts, and the movable rod of the electric push rod 93 and the ring sleeve 92 are connected by a connecting rod.

[0035] Multiple titanium ring forgings can be placed in the heating cavity at one time. However, after placing multiple titanium ring forgings, they have a certain weight, and it will be difficult to push up the annular support cylinder 5 directly. At this time, the electric push rod 93 can be directly started to work, and the annular support cylinder 5 can be driven by the electric push rod 93 to quickly take out the titanium ring forgings located in the heating cavity.

[0036] As Figure 3 、 Figure 8 、 Figure 9 As shown in the figure, it further includes a guiding component 10, and the guiding component 10 is arranged at the top of the constant temperature box 2; the guiding component 10 includes an L-shaped limiting plate 101 and a special-shaped limiting plate 102. Three L-shaped limiting plates 101 are fixed to the top of the constant temperature box 2 along the arc surface of the heating cavity by bolts, and the special-shaped limiting plate 102 is rotatably connected to the top of the constant temperature box 2, and there is a certain frictional resistance at the rotation connection. The special-shaped limiting plate 102 and the L-shaped limiting plate 101 are evenly and equidistantly distributed along the arc surface of the heating cavity, and the tops of the special-shaped limiting plate 102 and the L-shaped limiting plate 101 are both arc-shaped.

[0037] If the size of the titanium ring forging is close to the diameter of the heating cavity, it will be difficult to align the placement of the titanium ring forging with the heating cavity. At this time, the titanium ring forging can be guided and placed along the arc surface of the L-shaped limiting plate 101 from above the constant temperature box 2. Similarly, the special-shaped limiting plate 102 can be rotated down so that the special-shaped limiting plate 102 is flush with the top surface of the constant temperature box 2, and then it can be pushed in and placed from the side, so as to quickly place it.

[0038] As Figure 2 、 Figure 10 As shown in the figure, it further includes a limiting component 11, and the limiting component 11 is arranged on the side wall of the constant temperature box 2; the limiting component 11 includes a special-shaped long plate 111 and a first spring 112. The special-shaped long plate 111 is slidably connected to the side wall of the constant temperature box 2, the special-shaped long plate 111 is in sliding contact with the special-shaped limiting plate 102, and the first spring 112 is fixedly connected between the special-shaped long plate 111 and the installation main body 1.

[0039] In order to prevent the special-shaped limiting plate 102 from rotating and tipping over during the process of covering the cover 8, the special-shaped long plate 111 always keeps in contact with the special-shaped limiting plate 102 under the action of the first spring 112, so that the special-shaped limiting plate 102 is in an upright state. Only when the special-shaped long plate 111 is pressed down and no longer limits the special-shaped limiting plate 102, the special-shaped limiting plate 102 can be flipped over.

[0040] like Figure 1 、 Figure 11 As shown, it also includes a pushing component 12, the pushing component 12 is arranged on the side of the installation body 1, and the pushing part of the pushing component 12 is suspended above the constant temperature box; the pushing component 12 includes a support frame 121, an electric slide rail 122, a sliding frame 123 and a toggle plate 124, the support frame 121 is installed on the side wall of the installation body 1, the electric slide rail 122 is arranged on the support frame 121, the pushing part consists of a sliding frame 123 slidingly connected to the electric slide rail 122 and a toggle plate 124 fixed to the sliding frame 123 by bolts, the pushing part is suspended above the constant temperature box 2 and is driven by the electric slide rail 122 to slide left and right.

[0041] After a large number of titanium ring forgings are placed, they will be affected by the superimposed weight and the adhesion to the bottom of the constant temperature box 2 during the removal process, and it is difficult to push them by manpower alone. At this time, the electric slide rail 122 can be started to work, and the electric slide rail 122 can drive the pushing part to push the titanium ring forgings away, so as to achieve the effect of convenient removal.

[0042] like Figure 11 、 Figure 12 As shown, a buffer assembly 13 is also included, and a buffer assembly 13 is provided at the bottom of the toggle plate 124; the buffer assembly 13 includes a buffer block 131 and a second spring 132, and the bottom of the toggle plate 124 passes through the sliding connection buffer block 131, and the two ends of the buffer block 131 are elastic. The second spring 132 is sleeved between the buffer block 131 and the toggle plate 124, and the second spring 132 keeps the buffer block 131 in a uniform and symmetrical position on the toggle plate 124.

[0043] The toggle plate 124 on the pushing portion of the pushing assembly 12 may scratch the surface of the titanium ring forging during contact with the titanium ring forging. The contact between the buffer block 131 and the titanium ring forging can prevent the toggle plate 124 from contacting and scratching the titanium ring forging.
