Description

Technical Field

[0001] The present application relates to the technical field of material heating, and in particular to a waterless clamp device for an annular furnace. Background Art

[0002] The annular heating furnace is a continuous heating furnace in which the billet is heated while moving on the annular rotating furnace bottom. The feeding machine and discharging machine of the annular furnace are special equipment for feeding and discharging in the metallurgical industry. They are mainly composed of: clamp rod, clamp, lifting device, driving part of the billet feeding and discharging machine, clamp clamping and releasing device, hydraulic and electric control system. The clamp in the prior art is usually welded by clamp plates. In order to ensure the heating degree of the clamp, the clamp rod and the inside of the clamp are usually connected and cooled by water circulation. However, the clamp is prone to water leakage after long-term use, and the interior of the annular furnace is refractory material, which will cause damage after water ingress. Therefore, the clamp needs to be improved. The improved clamp is as follows:

[0003] Prior art 1: A material clamp for a ring heating furnace loading and unloading device with application number 201710702008.6 discloses a technical solution, including two parallel clamp rods, the two clamp rods are sleeved in a first double-hole bearing seat at the parts near the middle of the two clamp rods, the two clamp rods are sleeved in a second double-hole bearing seat at one end near the first double-hole bearing seat, the other ends of the two clamp rods are respectively provided with clamps with opposite notches, and there is also a device between the two clamp rods for controlling the opening and closing of the two clamp rods by controlling the rotation of the two clamp rods The driving mechanism of the invention; the clamps in the application are two identical and symmetrically arranged arc plates, the tops of the two arc plates are respectively fixed to the corresponding clamp rods along the length direction of the corresponding clamp rods, the central axis of the arc plate notch and the central axis of the corresponding clamp rod are located in the same plane and form an angle of 4°; a plurality of reinforcing rib plates for fixing to the corresponding clamp rods are arranged at intervals along the length direction of the clamps on the side opposite to the notch; the invention has a simple structure and low cost, and can meet the clamping requirements of the annular heating furnace loading and unloading device; but in the application, as Figure 1 As shown in the figure, combined with the description, it can be seen that the clamp is connected to the reinforcing rib plate, and the top of the clamp and the reinforcing rib plate are fixed to the bottom of the clamp rod. The clamp of this application mainly has the following technical problems:

[0004] 1. Because the clamp is only fixed to the bottom of the clamp rod, the strength of the clamp is problematic. If it is subjected to high temperature for a long time, it is easy to cause the clamp to deform, thus affecting the clamping effect;

[0005] 2. The clamp is connected to the bottom of the clamp rod. During installation, the clamp and the clamp rod are difficult to position, and the installation accuracy is low;

[0006] 3. Because the clamp is subjected to high temperatures, high-temperature materials are required. If the clamp and the clamp rod are made of different materials, the thermal expansion will be different and the heating will be uneven, thus affecting the service life. In addition, problems are prone to occur in the welds between different materials. If the clamp and the clamp rod are made of the same material, in order to ensure the high temperature resistance of the clamp, the clamp rod needs to be made of the same material as the clamp, which increases the manufacturing cost of the entire equipment.

[0007] In summary, it is necessary to provide a new technical solution to solve the above technical problems. Utility Model Content

[0026] The following is combined with Figure 1 To Attachment Figure 7The specific implementation of the utility model is described in detail. It should be noted that the specific implementation described here is only used to illustrate and explain the utility model, and is not used to limit the utility model.

[0027] Embodiment 1:

[0028] The present embodiment provides a waterless clamp device for an annular furnace, comprising two parallel clamp rods 1, and clamps 2 are installed on the two clamp rods 1. Preferably, each clamp rod 1 is provided with two clamps 2; the clamps 2 are driven by a clamp driving device, and the clamp driving device drives the clamping and loosening of the clamps 2. The clamp driving device is installed between the two clamp rods 1, wherein the clamp 2 comprises a clamp body 3, and the lower part of the clamp body 3 is provided with an integrally formed clamping part 4, and the two clamping parts 4 are used to clamp a workpiece 5. In the present embodiment, it is mainly used to clamp workpieces such as bars and steel pipes, and the upper part of the clamping part 4 is provided with There is an integrally formed mounting portion 6, and the clamp 2 is preferably cast. A mounting hole 7 is provided in the middle of the mounting portion 6, and the mounting hole 7 cooperates with the clamp rod 2. The diameter of the mounting hole 7 is preferably equal to the diameter of the clamp rod 1. The mounting portion 6 is installed with the clamp rod 1 through the mounting hole 7, and then welded around the entire circumference, thereby improving the strength of the clamp 2, ensuring that it can withstand high temperatures for a long time, and is not easy to cause deformation of the clamp 2, thereby improving the service life of the clamp 2; the mounting hole 7 and the clamp rod 1 are both circular, and the mounting method between the two makes it easy to position the clamp 2 and the clamp rod 1, ensuring the installation accuracy between the two, thereby improving the clamping effect.

[0029] Preferably, in order to absorb thermal expansion and avoid uneven heating of the clamp 2 which affects the service life of the clamp 2 , an absorption hole 8 is opened on the clamp body 3 .

[0030] Embodiment 2:

[0031] This embodiment can reduce the overall manufacturing cost and further improve the installation strength of the clamp 2. Specifically: a mounting rod 9 is installed in the clamp rod 1, and the diameter of the mounting rod 9 is preferably equal to the inner diameter of the clamp rod 1. The mounting rod 9 is connected to the clamp rod 1 by a full-circle welding method. The mounting portion 6 is fixed to the outside of the mounting rod 9 through the mounting hole 7, and the mounting portion 6 is connected to the mounting rod 9 by a full-circle welding method. The mounting rod 9 is made of the same material as the clamp 2, preferably stainless steel 2520. The clamp rod 1 is preferably a low-alloy high-strength structural steel with manganese 16. The design of the mounting rod 9 prevents a small part or the entire clamp rod 1 from entering the annular heating furnace. Therefore, it does not need to be made of the same material as the clamp 2, and ordinary manganese 16 low-alloy high-strength structural steel can be used. The length of the clamp rod 1 is relatively long, which can reduce the overall manufacturing cost.

[0032] Because the clamp 2 is subjected to a high temperature, high-temperature materials are required. The clamp 2 and the mounting rod 9 are made of the same material to ensure the same thermal expansion and uniform heating, thereby increasing the service life of the clamp 2. In addition, the welds between the same materials are less likely to have problems, further increasing the service life of the clamp 2. The longer clamp rod 1 can be made of ordinary manganese 16 low-alloy high-strength structural steel, and does not require stainless steel 2520, which can reduce the overall manufacturing cost.

[0033] Preferably, in order to facilitate the connection between the clamp 2 and the mounting rod 9, or the clamp 2 and the clamp rod 1, a positioning plane 10 is provided at the bottom of the mounting hole 7, and a mounting plane 11 matching the positioning plane 10 is provided at the bottom of the mounting rod 9 or the clamp rod 1.

[0036] A hollow mounting hole 12 for the clamp rod is provided inside the clamp rod 1, and a hollow mounting hole 13 for the mounting rod is provided in the middle of the mounting rod 9. The mounting rod 9 is installed in the hollow mounting hole 12 for the clamp rod, and the outer wall of the mounting rod 9 is connected to the hollow mounting hole 13 for the clamp rod by a full-circle welding method. The mounting rod 9 and the hollow mounting hole 13 for the clamp rod are also connected by a key connection and a pin connection to prevent the mounting rod 9 from rotating. The stability of the connection between the mounting rod 9 and the clamp rod 1 is further improved by the full-circle welding method; a circulating water inlet channel 14 is installed in the hollow mounting hole 12 for the clamp rod and the hollow mounting hole 13 for the mounting rod, and the circulating water inlet channel 14 is connected to the hollow mounting hole 23 for the clamp rod and the hollow mounting hole 13 for the mounting rod by welding and the like. The circulating water inlet channel 14 is close to one side of the clamp 2 A circulating water outlet 15 is provided at the end, and a circulating water outlet 16 is provided between the circulating water inlet 14 and the hollow mounting hole 12 of the clamp rod and the hollow mounting hole 13 of the mounting rod. The circulating water inlet 14 corresponds to the water inlet 17 arranged on the clamp rod 1, and the circulating water outlet 16 corresponds to the water outlet 18 arranged on the clamp rod 1; water flows into the circulating water inlet 14 through the water inlet 17, flows into the circulating water outlet 16 through the circulating water outlet 15, and then flows out through the water outlet 18 to realize the cooling water circulation. The present application only circulates inside the clamp rod 1 and the mounting rod 9, and circulating water does not need to be introduced into the clamp 2, so there will be no water leakage, which improves the service life of the clamp 2 and further prevents damage to the annular heating furnace, thereby improving the service life of the annular heating furnace.

The ends of the clamp rods 1 away from the clamps 2 are respectively installed with meshing gears 21, and the two meshing gears 21 are meshed with each other; the two clamp rods 1 are controlled to rotate synchronously by the push-pull action of the driving cylinder 19, thereby controlling the clamps 3 fixed on the two clamp rods 1 to be clamped or released.

[0040] The clamp rod 1 is provided with a clamp lifting frame 22, which is connected to the clamp rod 1 by welding or the like. The clamp lifting frame 22 is used to connect with the lifting device to control the application to move up and down; in addition, the application is connected with an external trolley to realize the forward or backward movement of the entire device, thereby realizing the loading or unloading of materials.

The clamp and the mounting rod are made of the same material, which can reduce the overall cost of use, and the clamp and the mounting rod are made of the same material and have the same thermal expansion, so that the heating is uniform and the risk of high-temperature deformation is reduced.
