Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of resistance furnaces, and particularly relates to a box-type resistance furnace. Background Art
[0002] Box-type resistance furnace is an industrial furnace used to heat workpieces or materials in the heat treatment industry. It mainly uses electric current to heat the electric heating elements or heating media in the furnace to heat the workpieces or materials. Resistance furnaces are used in the machinery industry for heating metals before forging, heating metal heat treatment, glass and ceramic baking, and other heat treatments and other heating purposes.
[0003] When using the existing box-type resistance furnace, workers are required to use pliers to place the workpiece to be heated in the furnace, and use pliers to take it out of the furnace after heating is completed. However, when the workers use the pliers to clamp, since the pliers need to enter the furnace and the temperature in the furnace is high, it is easy for the workers to be affected. When using the pliers, the heating wire in the furnace is bumped, which in turn causes damage to the heating element of the heating furnace and affects the heating work. At the same time, since the heated workpiece is easily oxidized during the heating process, the oxide residue falls into the heating furnace and is not easy to clean, which affects the heating effect.
[0004] Therefore, we propose a box-type resistance furnace to solve the above problems. Utility Model Content
[0005] In view of the above-mentioned existing problems, one of the purposes of the utility model is to provide a box-type resistance furnace, which can facilitate workers to store and retrieve heated workpieces more conveniently, quickly and safely, and at the same time can clean the oxides remaining from the heating work, thereby solving the problem that the heating elements in the furnace are easily damaged when using pliers to store and retrieve workpieces, and can ensure the cleanliness of the furnace.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A box-type resistance furnace includes: a bottom plate, a heating furnace is arranged on the top of the bottom plate; a heating element is arranged in the heating furnace; a placing and taking mechanism is arranged in the heating furnace, and the placing and taking mechanism includes: a slide groove opened on the inner wall of the heating furnace; a slider slidably connected in the slide groove; a placement plate arranged on the slider, and a plurality of through holes are present on the placement plate.
[0008] In one of the technical solutions disclosed in the present utility model, the placing and taking mechanism further includes:
[0009] The motor is arranged in the slide groove; the threaded rod is arranged in the slide groove, one end of the threaded rod is fixedly connected to the output shaft of the motor, and the threaded rod is threadedly connected to the slider.
[0010] In one of the technical solutions disclosed in the utility model, an ash dumping mechanism is arranged on the bottom side wall of the placement plate, and the ash dumping mechanism includes: a connecting rod, which is arranged on the bottom side wall of the placement plate; a rotating groove, which is opened on the side wall of the connecting rod; a rotating rod, which is rotatably connected in the rotating groove; and an ash hopper, which is arranged at one end of the rotating rod.
[0011] In one of the technical solutions disclosed in the present utility model, the ash dumping mechanism further includes:
[0012] A limiting groove is provided on the side wall of the rotating groove; a limiting block and a slider are connected in the limiting groove; a spring is arranged in the limiting groove, and one end of the spring is fixedly connected to the limiting block.
[0013] In one of the technical solutions disclosed in the present utility model, one end of the threaded rod away from the motor is connected to the slide groove through a bearing.
[0014] In one of the technical solutions disclosed in the present utility model, the tip of the ash loading hopper is arranged at an oblique angle.
[0015] In one of the technical solutions disclosed in the utility model, a push handle is fixedly connected to the top of the base plate.
[0016] In one of the technical solutions disclosed in the utility model, the heating furnace is provided with a high-temperature-proof glass window and a temperature gauge.
[0017] From the above description, it can be seen that the beneficial effects of the utility model are:
[0018] 1. By starting the motor to drive the threaded rod to rotate, the slider slides in the slide groove to drive the placement plate to move, and the placement plate can be removed from the heating furnace. This makes it convenient for workers to quickly place the workpiece to be heated on the placement plate, and also makes it convenient for workers to take the workpiece, thus avoiding the workers using pliers to place and take the workpiece in the furnace. The heating element may be bumped and damaged.
[0019] 2. The ash hopper can be moved out by moving the placement plate. The ash hopper collects and stores the oxidized residues produced by heating the workpiece. When the ash hopper is moved out of the heating furnace, the worker can press the ash hopper with tools such as pliers, so that the ash hopper can pour out the residues through the rotation of the rotating rod in the rotating groove. When the pressure on the ash hopper is lost, the spring pushes the limit block to rotate in the limit groove through the elastic force, and then drives the rotating rod to rotate, so that the ash hopper can be reset. In this way, the cleaning of the oxidized residues can be completed to avoid affecting the heating effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The resistance furnace is a type of heat treatment equipment that is frequently used in the heat treatment industry. It mainly uses electric current to make the heating elements inside the resistance furnace emit heat, thereby heating the samples inside the furnace. It is mainly used for production and experiments in the fields of ceramics, metallurgy, electronics, glass, chemicals, machinery, refractory materials, new material development, special materials, and building materials.
[0034] In the related art, the existing box-type resistance furnace requires the workpiece to be heated to be clamped and sent in with a clamp during heating, and also requires the use of a clamp to take it out when taking it out. However, due to the high temperature in the heating furnace and the need to extend the clamp into the furnace, it is easy to cause damage to the heating elements in the furnace by clamping. At the same time, the oxidation residue left on the workpiece cannot be cleaned, affecting the heating effect.
[0035] In order to solve the problems in the related art to a certain extent, the present application implements a box-type resistance furnace. When in use, by starting the motor 240 to rotate forward to drive the threaded rod 250 to rotate, the slider 220 can be driven to slide in the slide groove 210, and the placement plate 230 can be moved out of the heating furnace. At this time, the worker can place the workpiece on the placement plate 230, and the motor 240 can be reversed to drive the placement plate 230 into the heating furnace for heating. After the heating is completed, the motor 240 can be controlled to rotate forward again to move the heating element out of the heating furnace, and the worker can collect it and load the ash hopper 340 at the same time. The ash hopper 340 is pressed by using a tool to make it rotate in the rotating groove 320 through the rotating rod 330, and the oxidized residue is poured out. The pressure on the ash hopper 340 is lost, and the elastic force of the spring 370 pushes the limit block 360 to move in the limit groove 350 to drive the rotating rod 330 to rotate, and then the ash hopper 340 is reset. Combined with the above, the workpiece can be placed and taken out quickly, conveniently and safely, avoiding damage to the heating elements in the heating furnace 120 and affecting the work, and the oxidized residue can be cleaned well to avoid affecting the heating effect.

[0038] When in use, the slider 220 slides in the slide groove 210 to drive the placement plate 230 to be moved out of the heating furnace 120, making it convenient for workers to place and take out the heated workpiece. The through holes on the placement plate 230 can allow the oxidized residue of the workpiece to fall off, and facilitate better heating.
