Technical Field

[0001] The present application belongs to the technical field of workpiece heating equipment, and in particular, relates to a heating furnace. Background Art

[0002] Forging is a common process in mechanical processing. In order to achieve certain characteristics, the material needs to be forged to obtain this property. Before forging, the material must be heated at high temperature. The heating furnace is an indispensable processing equipment in forging, which uses coal combustion, electric power generation or gas combustion for heating.

[0003] The existing Chinese patent with publication number CN111085654A discloses a heating furnace, including a heating chamber, which has an inlet and an outlet, a conveyor rail arranged along the direction from the inlet to the outlet is arranged inside, and a toggle mechanism for driving the conveyor rail to rotate is arranged outside; a lifting device, one side of which is provided with a hopper and the upper part is provided with a discharge port; a discharge track, which is obliquely arranged between the discharge port and the inlet; and a support plate and a toggle mechanism, the support plate is installed at the inlet of the heating chamber, and the toggle mechanism is installed on the support plate and is located at the inclined lower end of the discharge track.

[0004] Although the above-mentioned heating furnace can heat the workpiece, the energy loss during the heating process is relatively high, and improvements are made to this end. Summary of the invention

[0005] The purpose of this application is to provide a heating furnace to address the above-mentioned technical problems, improve the heating efficiency of the workpiece, reduce energy loss during the heating process, and save resources.

[0006] The present application provides a heating furnace, including a heating furnace body, wherein the heating furnace body includes:

[0007] Feeding mechanism, used for automatically feeding workpieces;

[0008] A heating mechanism, comprising a heating chamber, wherein the heating mechanism is used to heat a workpiece;

[0009] A material unloading mechanism is used to unload the workpiece that has been heated on the heating mechanism;

[0010] The movable frame is movably connected to the heating furnace body;

[0011] Wherein, the heating mechanism further includes a heat insulation cover and a buffer zone, the buffer zone is placed at the inlet end of the heating chamber, the heat insulation cover is placed at the outlet end of the heating chamber, and the feeding mechanism is placed on the mobile frame.

[0012] The workpieces are arranged neatly through the feeding mechanism, and are allowed to enter the heating mechanism at a uniform and stable speed for heating. The heating chamber is connected to a gas source, and the workpieces are heated by the high temperature generated by the combustion of the gas in the heating chamber. When the workpieces are heated to a specified temperature, the workpieces are pushed out of the heating mechanism through the unloading mechanism to complete the heating. The heat escape from the outlet end of the heating chamber is reduced by a heat insulation cover, and the combustion of the gas causes the flame to spray out from the inlet end of the heating chamber. The upward spraying of most of the flames is changed through a buffer zone, and the workpieces located in the buffer zone are further preheated, thereby improving the gas utilization rate and saving resources.

[0013] The moving frame can be placed on the heating furnace body and can move, and the feeding mechanism is installed on the moving frame and moves with the moving frame.

[0014] Furthermore, the heating mechanism also includes:

[0015] A first conveyor belt is placed in the heating chamber, wherein the first conveyor belt comprises a plurality of conveying members, and the conveying members are hingedly connected;

[0016] A first conveying wheel, wherein the first conveying wheel is provided with a limiting portion, and the limiting portion is used to limit a hinged portion of the conveying member;

[0017] An installation shaft, installed and connected with the first conveying wheel;

[0018] Wherein, the mounting shaft is provided with a heat exchange cavity, the axis of the heat exchange cavity is the same as the axis of the mounting shaft, and rotating joints are provided at both ends of the mounting shaft, and the coolant enters the heat exchange cavity through the rotating joints for heat exchange and cooling. When the workpiece is placed on the first conveyor belt, if the workpiece has a circular cross-section, it is placed in the gap between the two conveying members, and if the workpiece has a planar structure, it is placed on the upper surface of the conveying member through the plane. The first conveying wheel is installed at the inlet and outlet ends of the heating chamber, wherein the first conveying wheel located at the outlet end of the heating chamber is movably connected to the heating furnace body, and the first conveying wheel located at the inlet end of the heating chamber is movably connected to the movable frame.

[0019] The first conveyor belt is used to convey workpieces. The first conveyor belt is hinged and connected end to end through a plurality of conveying members. The first conveyor belt is installed and connected through a first conveying wheel and a mounting shaft and has high stability. The rotary joints are installed at both ends of the mounting shaft and connected to a coolant. By continuously circulating the coolant in the heat exchange cavity, the temperature of the mounting shaft is stabilized, the structural stability of the mounting shaft is ensured, and the high temperature is reduced and transmitted to other devices through the mounting shaft.

[0020] The limiting part is used to prevent the hinged part of the conveying member on the first conveyor belt from moving in the axial direction of the first conveyor wheel, thereby improving the structural stability between the first conveyor belt and the first conveyor wheel. The first conveyor wheel located at the inlet end of the heating chamber is movably connected with the movable frame. When the heating chamber is heated, the first conveyor belt is affected by the high temperature and its length becomes longer. The movable frame is moved and adjusted to keep the first conveyor belt in a tensioned state at all times, thereby ensuring the structural stability between the first conveyor belt and the first conveyor wheel.

[0021] There are many types of workpieces to be heated. Workpieces with cylindrical or elliptical cross-sections are easy to roll and are suitable for being placed in the gap between two conveyors for transportation. If the workpiece to be heated has a flat structure on the surface, such as a polygonal structure such as a square, pentagonal, hexagonal or semicircular cross-section, it can be placed on the upper surface of the conveyor for transportation.

[0026] Wherein, the first driving cylinder is movably connected to the rotating seat and the moving frame.

[0027] The rotating seat and the hook claw are hinged by a rotating shaft, and the rotating seat is hinged on the mounting shaft. When the first driving cylinder pushes the rotating seat to rotate, the hook claw pulls the conveying member on the first conveyor belt to move forward. When the first driving cylinder pushes the rotating seat to rotate and reset, the hook claw retreats and hooks the next conveying member. Through the structure among the hook claw, the rotating seat and the first driving cylinder, the first conveyor belt can move stably, and the distance of movement of the first conveyor belt each time can be controlled to be the same, so that the workpiece is stably placed on the first conveyor belt.

[0039] The push rod is pushed by the second driving cylinder to move, so as to push the workpiece placed on the first conveyor belt and push it out of the heat insulation cover through the through hole. The through hole on one side of the mounting seat corresponds to the second driving cylinder and the push rod, and the through hole on the other side is installed on the guide member, so as to guide the workpiece to slide from the through hole to other devices.

[0040] Furthermore, the heating chamber comprises:

[0087] The unloading mechanism 300 is used to unload the workpiece that has been heated on the heating mechanism 200;

[0088] The movable frame 600 is movably connected to the heating furnace body 001;

[0089] The heating mechanism 200 further includes a heat shield 220 and a buffer zone 230 . The buffer zone 230 is disposed at the inlet end of the heating chamber 210 . The heat shield 220 is disposed at the outlet end of the heating chamber 210 . The feeding mechanism 100 is disposed on the movable frame 600 .

[0090] The loading mechanism 100 is used to arrange the workpieces neatly, so that the workpieces enter the heating mechanism 200 at a uniform and stable speed for heating. The heating chamber 210 is connected to a gas source, and the workpieces are heated by the high temperature generated by the combustion of the gas in the heating chamber 210. When the workpieces are heated to a specified temperature, the workpieces are pushed out of the heating mechanism 200 by the unloading mechanism 300 to complete the heating. The heat escape from the outlet end of the heating chamber 210 is reduced by the heat insulation cover 220.
