Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for detecting the mechanical properties of steel, and particularly relates to a water cooling device applicable to round bar blank specimens. Background Art

[0002] At present, after the high-temperature round bar blank specimen is water-cooled + tempered, it is machined into a round bar tensile specimen by turning to detect the tensile properties of the steel after water quenching and tempering treatment; since one end of the round bar blank specimen is clamped inside the chuck and a tapered groove is provided at the end face of the other end, the clamping center point of the tailstock is used to achieve the stable rotation of the round bar blank specimen, and during the stretching process, both ends of the round bar tensile specimen are arranged inside the fixture of the tensile testing machine. Therefore, the two ends of the round bar blank specimen do not have very high requirements for the water cooling intensity; operators usually use pliers to place the high-temperature round bar blank specimen in the water tank and shake it. However, due to non-standard operation, the round bar blank specimen cannot be guaranteed to enter the water vertically. Therefore, the round bar blank specimen is very likely to bend under the action of tissue stress, which will cause two problems. On the one hand, it will increase the processing difficulty of the round bar tensile specimen, and on the other hand, it will affect the test results of the round bar tensile specimen. In view of this, it is necessary to develop a device specifically used for water cooling the round bar blank specimen.

[0003] After retrieval, it is found that there are three patent literatures most relevant to the technology of the present utility model, and the specific contents are described as follows:

[0004] Patent document CN 201610037025.8 discloses a water cooling device for an optical fiber preform, which mainly includes a water cooling box, an upper cover, a left cover, a right cover, a bearing, a connector, a driving device, a limiting block and a heat exchange device. Since the driving device is used to drive the optical fiber preform to rotate, thereby agitating the air flow generated inside the water cooling box, and at the same time, the continuously injected cooling water is used to provide continuous low temperature inside the water cooling box, this device can shorten the cooling time of the optical fiber preform. However, this device is only applicable to the water cooling of optical fiber preforms and not to the water cooling of round bar blank specimens.

[0005] Patent document CN 201621071231.2 discloses a water cooling device for an optical fiber preform, which mainly includes a water cooling box, an upper cover, a left cover, a right cover, a bearing, a connector, a solenoid valve, a crankshaft, a driving motor, a positioning piece, a bolt, a limiting block and a heat exchange device. Since there is a mixed cooling environment inside the water cooling box, which can continuously absorb the heat of the optical fiber preform, combining the technologies of air cooling and water cooling, this device can shorten the cooling time of the optical fiber preform. However, this device is only applicable to the water cooling of optical fiber preforms and not to the water cooling of round bar blank specimens.

[0006] Patent document CN 202123396242.1 discloses a water-cooling device for a rotating shaft, which mainly includes a connecting seat, a spacer sleeve, a support block, an annular groove, a sealing ring, an annular recess, a bearing, a convex ring and an annular end plate. Since a cooling cavity is provided between the inner shaft and the outer shaft, the spacer sleeve enables the coolant to be stratified and circulate within the cooling cavity, which can greatly increase the contact area between the coolant and the rotating shaft. Therefore, the cooling effect of this device has been greatly improved. However, this device is only applicable to the water-cooling of the rotating shaft and not to the water-cooling of round bar blank specimens. Summary of the Utility Model

[0065] Definition rules for the swinging direction of the sixth bracket of the water-cooling device applicable to round bar blank specimens provided by the present utility model

[0066] Combined with Figure 4 As shown in the top view structural schematic diagram of the device of the present utility model, for the convenience of description, the four sixth brackets 8 are respectively defined as ①, ②, ③, and ④. Among them, the eight bearing sections 803 of the four sixth brackets 8 are all swinging shafts;

[0067] Assume that initially the four sixth brackets 8 are all arranged front and back. After simplification, as Figure 24 shown, ① and ④ swing 90 degrees counterclockwise at the same time, and ② and ③ swing 90 degrees clockwise at the same time. Then, the four sixth brackets 8 are all arranged left and right. This swinging direction of the sixth bracket 8 is defined as the positive direction;

[0068] Assume that initially the four sixth brackets 8 are all arranged left and right. After simplification, asFigure 25 As shown, the first and the fourth simultaneously swing 90 degrees clockwise, and the second and the third simultaneously swing 90 degrees counterclockwise, so that the four sixth brackets 8 are arranged front and back. This swinging direction of the sixth bracket 8 can be defined as the reverse direction.

[0069] Usage method of the water cooling device applicable to round bar blank specimens provided by the present utility model

[0070] Step 1: As shown in Figures 1 to 5 At the initial stage, the four sixth brackets 8 are arranged front and back. First, along the four connecting rods 10, raise the lower third bracket 3 out of the fourth groove 903 of the seventh bracket 9, then inject a certain amount of clear water into the fourth groove 903, and then simultaneously swing the four sixth brackets 8 in the positive direction so that the four sixth brackets 8 are arranged left and right.

[0071] Step 2: Then screw out the four screws 11 from the four third screw holes 308 of the lower third bracket 3 and then draw them out from the four seventh through holes 503 of the two lower fifth brackets 5 to facilitate moving the upper third bracket 3, and then raise the upper third bracket 3 along the four connecting rods 10 to facilitate threading the round bar blank specimen 13.

[0072] Step 3: Then pass the two heated round bar blank specimens 13 through the two frustum-shaped through holes formed by the four through grooves 804 of the four sixth brackets 8 and drop them into the two second grooves 306 of the lower third bracket 3, and then simultaneously swing the four sixth brackets 8 in the reverse direction so that the four sixth brackets 8 are arranged front and back to facilitate water cooling of the round bar blank specimen 13.

[0073] Step 4: Then lower the upper third bracket 3 along the four connecting rods 10, then pass the four screws 11 through the four seventh through holes 503 and screw them into the four third screw holes 308, and then repeatedly raise and lower the two third brackets 3 along the four connecting rods 10. During this period, both of the two third brackets 3 should be kept in the water until no more steam comes out of the water surface.

[0074] Supplementary note: The water-cooling device applicable to round bar blank specimens provided by the present utility model is designed with a symmetrical structure. First, according to the diameter specification and fixed-length of the round bar blank specimens, a plurality of specifications of the device of the present utility model should be designed and manufactured to match them; the certain amount of water means that the distance from the water surface to the upper end surface of the eighth body 901 of the seventh support 9 is 100 mm, which can not only ensure that there is enough water but also ensure that the water will not overflow; before threading the round bar blank specimen 13, it should be ensured that the two third supports 3 and the four sixth supports 8 are in a dry state. If the surfaces of the two third supports 3 and the four sixth supports 8 are stained with moisture, the moisture should be wiped off; the fourth groove 903 of the seventh support 9 should have sufficient depth to ensure that the movement of repeatedly lifting and lowering the two third supports 3 can be completed in the water; in order to simplify the operation, when the upper third support 3 descends onto the upper fourth support 4, the four seventh through-holes 503 of the two lower fifth supports 5 and the four third screw holes 308 of the lower third support 3 are in an aligned relationship; the diameter of the second groove 306 of the third support 3 should be larger than the diameter of the round bar blank specimen 13, that is, the second groove 306 and the round bar blank specimen 13 are in an interference fit, and the third through-hole 307 is used in combination to increase the cooling intensity of the two ends of the round bar blank specimen 13.

[0075] It can be seen from the embodiments that by using the water-cooling device applicable to round bar blank specimens provided by the present utility model, the purpose of water-cooling two round bar blank specimens simultaneously can be achieved. The device of the present utility model has the characteristics of low manufacturing cost, simple operation and good use effect.

[0076] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
