Description

Technical Field

[0001] This utility model relates to the field of surface heat treatment technology for metal parts, specifically to an adjustable surface heat treatment processing equipment for metal parts. Background Technology

[0002] Surface heat treatment of metal parts is a technique that alters the surface structure and properties of a metal by heating, holding, and cooling the surface layer while maintaining the original properties of the core. This treatment method is widely used to improve the wear resistance, corrosion resistance, fatigue strength, and other properties of parts.

[0003] For example, the patent application number published on the China Patent Network is 202320225650.0, and the patent name is: A heat treatment device for the surface of mechanical metal parts. It includes a heat treatment device body, a support column located at the lower end of the heat treatment device body, and a cabinet door located at the front of the heat treatment device body. The upper end of the heat treatment device body is provided with a first vent hole. When using the heat treatment device for the surface of mechanical metal parts, the mechanical metal parts are first placed inside the heat treatment device body. Then, the heat treatment device body and the exhaust gas collection device are connected to an external power source. Next, the switch button is pressed to heat the heating tube. The heating tube will cause the temperature inside the heat treatment device body to rise, thereby heat treating the surface of the mechanical metal parts. During the heat treatment process, the mechanical metal parts will generate exhaust gas. The exhaust gas will enter the interior of the exhaust gas collection device through the connecting pipe. The exhaust gas collection device facilitates the collection of exhaust gas generated during heating and avoids the exhaust gas from affecting the environment.

[0004] However, the height of the flame-retardant blocks used to block flames inside existing heat treatment equipment is fixed. When the metal parts are too tall, the flames sprayed on the surface of the parts will pass over the flame-retardant blocks and come into contact with the inner wall of the furnace, causing the furnace to be directly baked by high temperature.

[0005] Therefore, it is necessary to redesign and modify the adjustable metal surface heat treatment equipment. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an adjustable metal surface heat treatment processing equipment, which has the advantage of being able to adjust the height of the flame-retardant block. This solves the problem that in existing heat treatment equipment, the height of the flame-retardant block used to block flames is fixed, and when the height of the metal part is too high, the flame sprayed on the surface of the part will pass over the flame-retardant block and come into contact with the inner wall of the furnace, causing the furnace body to be directly baked by high temperature.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable metal part surface heat treatment processing equipment, including a furnace body;

[0008] Flame-retardant bricks are installed inside the furnace body;

[0009] An opening is provided at the bottom right side of the furnace body, which communicates with the inner wall of the furnace body.

[0011] As a preferred embodiment of this utility model, a drive motor is fixedly connected to the back of the upright plate, and the output end of the drive motor is fixedly connected to the rear end of the bidirectional screw.

[0012] As a preferred embodiment of this invention, a protective cover is fixedly connected to the right side of the furnace body. The protective cover is fitted onto the surface of the bidirectional screw and blocks the opening.

[0013] As a preferred embodiment of this utility model, a movable block is fixedly connected to the right side of the inner wall of the furnace body, and a baffle plate is movably connected to the surface of the movable block via a pin.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 4 As shown, the present invention provides an adjustable metal part surface heat treatment processing equipment, including a furnace body 1;

[0029] Flame-retardant bricks 2 are installed inside the furnace body 1;

[0030] An opening 3 is provided at the bottom right side of the furnace body 1. The opening 3 is connected to the inner wall of the furnace body 1. A bracket 4 is fixedly connected to the right side of the flame-retardant brick 2. A connecting block 6 is installed on the right side of the furnace body 1 through an adjustment structure 5. A crank 7 is movably connected to the surface of the connecting block 6 through a pin. The side of the crank 7 away from the connecting block 6 passes through the opening 3 and extends to the right side of the bracket 4. The bracket 4 and the crank 7 are movably connected through a pin. The adjustment structure 5 can control the two connecting blocks 6 to move towards each other and push the flame-retardant brick 2 up and down.

[0031] refer to Figure 3 The adjusting structure 5 includes a vertical plate 8 fixedly connected to the right side of the furnace body 1. A bidirectional screw 9 is movably connected to the inner side of the vertical plate 8 via a bearing. A connecting block 6 is sleeved on the surface of the bidirectional screw 9 and threadedly connected to the bidirectional screw 9.

[0032] As a technical optimization of this utility model, the bidirectional screw 9 directly drives the two connecting blocks 6 on both sides to move in opposite directions, ensuring that the flame-retardant brick 2 rises and falls smoothly and symmetrically. The threaded connection has a self-locking function, and the flame-retardant brick 2 can be fixed at any height, avoiding positional displacement caused by vibration during processing.

[0033] refer to Figure 3 A drive motor 10 is fixedly connected to the back of the upright plate 8, and the output end of the drive motor 10 is fixedly connected to the rear end of the bidirectional screw 9.

[0034] As a technical optimization of this utility model, the height of the flame-retardant brick 2 can be adjusted with one key by driving the transmission motor 10, which reduces the intensity of manual operation and improves efficiency. By controlling the speed and direction of the transmission motor 10, the lifting speed and stroke of the flame-retardant brick 2 can be precisely adjusted to meet the needs of different working conditions.

[0035] refer to Figure 2 A protective cover 11 is fixedly connected to the right side of the furnace body 1. The protective cover 11 is fitted onto the surface of the bidirectional screw 9 and covers the opening 3.

[0036] As a technical optimization of this utility model, the protective cover 11 isolates the high-temperature smoke and dust inside the furnace body 1, preventing the bidirectional screw 9 and transmission components from being contaminated or corroded. At the same time, it can shield the moving parts to prevent operators from accidentally touching them and causing mechanical injury.

[0037] refer to Figure 1 A movable block 12 is fixedly connected to the right side of the inner wall of the furnace body 1. A baffle plate 13 is movably connected to the surface of the movable block 12 via a pin. The side of the baffle plate 13 away from the movable block 12 extends to the left side of the flame-retardant brick 2. A heat insulation plate 14 located on top of the flame-retardant brick 2 is fixedly connected to the surface of the baffle plate 13.

[0038] As a technical optimization of this utility model, the angle of the baffle plate 13 is adaptively adjusted as the flame-retardant brick 2 rises and falls, so that it always fits the left side of the flame-retardant brick 2, forming a continuous heat insulation barrier.

[0039] refer to Figure 1 A spring plate 15 is fixedly connected to the top of the baffle plate 13. The side of the spring plate 15 away from the baffle plate 13 contacts the inner surface of the furnace body 1. The spring plate 15 is elastic.

[0040] As a technical optimization of this utility model, the elastic deformation capability of the spring plate 15 compensates for the assembly gap between the inner wall of the furnace body 1 and the baffle plate 13, ensuring a tight fit under high temperature conditions.

[0041] The working principle and usage process of this utility model are as follows: When processing metal parts of different heights, the operator starts the drive motor 10, which drives the bidirectional screw 9 to rotate. Since the threads on both sides of the screw are in opposite directions, the two connecting blocks 6 fitted on the screw move towards each other. The movement of the connecting blocks 6 is transmitted to the flame-retardant system through the crank 7. One end of the crank 7 is movably connected to the connecting blocks 6 through a pin, and the other end passes through the opening 3 of the furnace body 1 and is connected to the support 4 on the right side of the flame-retardant brick 2. When the connecting blocks 6 move towards each other, the crank 7 pushes the support 4 to rise; thus adapting to metal parts of different heights. When the flame-retardant brick 2 is raised or lowered, the movable block 12 on the right side of the inner wall of the furnace body 1 and the shield... The baffle 13 works in concert. The baffle 13 is hinged to the movable block 12 via a pin. Its free end rotates around the movable block 12 as the height of the flame-retardant brick 2 changes. When the flame-retardant brick 2 rises, the baffle 13 tilts upward; when it falls, it swings back. The heat insulation plate 14 at the top always covers the top of the flame-retardant brick 2, forming a continuous heat insulation barrier. At the same time, the spring plate 15 on the baffle 13 is in close contact with the inner wall of the furnace body 1 due to its elasticity, ensuring dynamic sealing and preventing the leakage of flames or high-temperature gases. During the heat treatment process, the flame is sprayed onto the surface of the metal parts. The adjusted height of the flame-retardant brick 2, together with the baffle 13 and the heat insulation plate 14, constitutes an adjustable flame-retardant barrier, preventing the flame from directly contacting the inner wall of the furnace body 1.

[0042] In summary: This adjustable metal surface heat treatment equipment allows the height of the flame-retardant brick 2 to be flexibly raised and lowered according to the size of the metal part through the linkage of the crank 7 and the bracket 4, preventing the flame from crossing the inner wall of the furnace body 1 of the flame-retardant brick 2. The pin connection between the crank 7 and the connecting block 6 ensures stable transmission and prevents the flame-retardant brick 2 from shifting or getting stuck during the raising and lowering process.
