Abstract
Description
Technical Field
[0001] This utility model relates to the field of bar stock venting, specifically to a sensor venting rod. Background Technology
[0002] The emptying of the bar stock in the sensor requires the use of an emptying rod. To avoid being heated by induction when the emptying rod is inserted into the sensor, the emptying rod is usually equipped with a cooling circulating water channel inside.
[0003] However, the above method, due to the low temperature of the venting rod, not only reduces the temperature of the bar stock in contact with it, affecting the original temperature of the bar stock, but also increases the equipment cost due to the need for water circulation.
[0004] To address the aforementioned problems, this utility model designs and manufactures a sensor venting rod to overcome the above-mentioned defects. Summary of the Invention
[0005] To address the problems existing in the prior art, this utility model provides a sensor venting rod that can reduce the heat generated by the venting rod without affecting the temperature of the bar material in contact with it.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sensor venting rod, comprising at least one round rod, wherein at least one concave square groove is provided on the circumference of the side wall of the round rod;
[0007] The end face of one end of the round rod is provided with a protrusion, and the end face of the other end of the round rod is provided with a groove. The protrusion of the adjacent round rod can be coaxially connected after cooperating with the groove.
[0008] Preferably, the diameter of the round rod is the same as the diameter of the bar stock to be emptied.
[0009] Preferably, the depth of the concave groove is 1 / 4 to 3 / 4 of the radius of the round rod.
[0010] Preferably, the width of the concave square groove is 1 / 4 to 3 / 4 of the radius of the round rod.
[0011] Preferably, the concave square groove is provided in two places, and the two concave square grooves are respectively provided on both sides of the protruding block.
[0012] Preferably, the end of the groove is provided with a transition bevel.
[0013] Preferably, the material of the round rod is the same as the material of the bar stock to be emptied.
[0014] The advantages of this utility model are:
[0015] 1. After the venting rod of this utility model is inserted into the sensor, the concave square groove is equivalent to cutting off the eddy current on the circumferential surface of the round rod, thereby reducing the rate of temperature rise of the round rod surface. Moreover, this structure will not reduce the temperature in the sensor, nor will it affect the temperature of the contacting bar.
[0016] 2. This utility model utilizes the protrusion and groove at the end of the round rod to achieve segmented installation of the venting rod, reducing its space requirements at one end of the sensor. Attached Figure Description

[0020] In the diagram: 1. Round rod; 2. Concave square groove; 3. Protruding block; 4. Groove. Detailed Implementation
[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.
[0022] like Figures 1 to 3 As shown, a sensor venting rod includes at least one round rod 1. The diameter of the round rod 1 is the same as the diameter of the bar to be vented, and the material of the round rod 1 is the same as that of the bar to be vented. At least one concave square groove 2 is provided on the circumference of the side wall of the round rod 1. After the venting rod is inserted into the sensor, the setting of the concave square groove 2 is equivalent to cutting off the eddy current on the circumferential surface of the round rod 1, thereby reducing the rate of temperature rise of the surface of the round rod 1. Moreover, this structure will not reduce the temperature in the sensor, nor will it affect the temperature of the bar in contact.
[0023] Specifically, the depth of the concave square groove 2 is 1 / 4 to 3 / 4 of the radius of the round rod 1, and the width of the concave square groove 2 is 1 / 4 to 3 / 4 of the radius of the round rod 1, which can ensure the structural strength of the round rod 1 itself.
[0024] The circular rod 1 of this invention has a protrusion 3 on one end face and a groove 4 on the other end face. The protrusion 3 of another adjacent circular rod 1 can be coaxially connected after engaging with the groove 4. Preferably, the end of the groove 4 has a transition bevel to facilitate the insertion and engagement with the protrusion 3 of another circular rod 1.
[0025] The concave square groove 2 is preferably provided in two places, and the two concave square grooves 2 are respectively provided on both sides of the protruding block 3 to ensure that the processing of the protruding block 3 and the concave square groove 2 do not affect each other.
[0026] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
