Description

Technical Field

[0001] This utility model relates to the field of heat treatment of metal products, and more specifically, to a heat treatment device for metal products that facilitates loading and unloading. Background Technology

[0002] Heat treatment of metal products is a processing technology that uses specific processes such as heating, heat preservation, and cooling to change the internal structure and physicochemical properties of metal materials, thereby improving the mechanical properties of metal products such as strength, hardness, wear resistance, and toughness, enhancing their corrosion resistance and fatigue resistance, and meeting the diverse performance requirements of metal materials for different engineering applications.

[0003] The prior art disclosed in patent publication (announcement) number CN215162977U is a heat treatment device for metal products that facilitates feeding and unloading. It includes a worktable, with support columns fixedly connected to the four corners of the bottom surface of the worktable. A notch is opened in front of the upper surface of the worktable, and rotating rollers are rotatably installed on the left and right sides inside the notch. A motor is fixedly installed on the left side of the front surface of the worktable, and the output end of the motor is fixedly connected to one end of the support shaft of the left rotating roller. A conveyor belt is connected between the left and right rotating rollers. A support plate is fixedly connected to the rear side of the upper surface of the worktable. A second electric push rod is fixedly installed in the middle of the upper surface of the moving plate. A lifting plate is fixedly connected to the output end of the second electric push rod. Pneumatic suction cups are fixedly embedded in the front and rear sides of the lower left and lower right ends of the lifting plate.

[0004] The aforementioned patent document discloses a heat treatment device for metal products that facilitates material loading and unloading. While this solves the problems of high labor intensity and low production efficiency associated with manual material loading and unloading in traditional metal product surface heat treatment, its shortcomings are as follows:

[0005] In the aforementioned patented device, metal products are directly conveyed via a conveyor belt after heat treatment (such as quenching, tempering, and other high-temperature processes). However, traditional conveyor belts (such as those made of rubber or PVC) have limited temperature resistance (usually ≤100℃). When high-temperature metal parts (up to 300-800℃) come into contact with the conveyor belt, it can cause the conveyor belt surface to soften, stick, or undergo permanent deformation. In some cases, local overheating can even lead to a risk of combustion, seriously affecting the equipment's lifespan and production safety.

[0006] Furthermore, in the aforementioned patented device, the pneumatic suction cup is fixedly installed, which cannot adapt to metal products of different shapes and sizes, resulting in unstable or failed gripping, which seriously affects production continuity and product safety.

[0007] Therefore, we have made improvements to this and proposed a heat treatment device for metal products that facilitates loading and unloading. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a heat treatment device for metal products that facilitates loading and unloading, thus solving the problems mentioned in the background art.

[0009] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

A second hydraulic rod is fixedly installed on the upper surface of the connecting plate, and a clamping mechanism is connected to the telescopic end of the lower side of the second hydraulic rod. A heat treatment assembly is fixedly installed on the upper surface of the base.

[0013] The conveying mechanism includes a rotating shaft, and there are several rotating shafts. The rotating shafts are rotatably connected inside the groove. Conveying rollers are fixedly installed on the outside of the rotating shafts. The conveying rollers are made of alumina-ceramic fiber composite material.

[0014] As a preferred technical solution of this application, one end of each of the plurality of rotating shafts extends into a groove, and two sprockets are fixedly installed on the outside of one end of each rotating shaft, and the corresponding sprockets on two adjacent rotating shafts are connected by chain meshing to form a multi-stage chain drive structure.

[0015] As a preferred technical solution of this application, a fixing cover is fixedly installed on one side surface of the base, and the fixing cover is disposed outside several chains. A first motor is fixedly installed on the surface of the fixing cover, and the output end of the first motor is fixedly connected to one end of a rotating shaft on one side.

[0016] As a preferred technical solution of this application, the clamping mechanism includes a fixed frame, and a threaded rod is rotatably connected inside the fixed frame. The thread directions at both ends of the threaded rod are opposite, and clamping plates are threadedly connected to the outside of both ends of the threaded rod. Both clamping plates are slidably connected within the fixed frame.

[0017] As a preferred technical solution of this application, a second motor is fixedly installed on one side surface of the fixed frame, and the output end of the second motor is fixedly connected to one end of the threaded rod.

[0018] As a preferred technical solution of this application, two limiting rods are fixedly installed inside the fixed frame, and both clamps are slidably connected to the limiting rods.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the scheme of this application:

[0021] 1. In the conveying mechanism of this device, the conveyor rollers are made of alumina-ceramic fiber composite material. This material has excellent high-temperature resistance, capable of withstanding temperatures of 300-800℃ or even higher, effectively avoiding the softening, adhesion, deformation, and combustion risks that occur when traditional rubber or PVC conveyor belts come into contact with high-temperature metal parts. This ensures stable operation of the equipment in high-temperature environments, extends its service life, eliminates safety hazards, and ensures production safety.

[0022] 2. The clamping mechanism of this device is driven by a second motor to rotate a threaded rod. Because the threads at both ends of the threaded rod are in opposite directions, the two clamping plates slide towards or away from each other within the fixed frame, achieving stable clamping of metal products of different shapes and sizes. Compared to fixed-installation pneumatic suction cups, this clamping mechanism can flexibly adapt to a variety of metal products, greatly improving the stability and success rate of gripping, ensuring production continuity, enhancing product safety, and increasing the versatility and practicality of the device.

[0034] To address the technical problems in the background section, the following heat treatment apparatus for metal products, which facilitates loading and unloading, is provided:

[0035] Combination Figure 1 - Figure 4As shown, the present invention provides a heat treatment device for metal products that facilitates loading and unloading. It includes a base 1, a groove 2 on one side of the upper surface of the base 1, and a conveying mechanism 3 inside the groove 2. A fixing plate 4 is fixedly installed on one side of the upper surface of the base 1, and two first hydraulic rods 5 are fixedly installed inside the fixing plate 4. A connecting plate 6 is fixedly connected to the telescopic end of the first hydraulic rods 5. A second hydraulic rod 7 is fixedly installed on the upper surface of the connecting plate 6, and a clamping mechanism 8 is connected to the telescopic end of the lower side of the second hydraulic rod 7. A heat treatment assembly 9 is fixedly installed on the upper surface of the base 1. The conveying mechanism 3 includes a rotating shaft 301, and several rotating shafts 301 are provided. All rotating shafts 301 are rotatably connected inside the groove 2. Conveying rollers 302 are fixedly installed on the outside of each rotating shaft 301, and the conveying rollers 302 are made of alumina-ceramic fiber composite material.

[0036] In this embodiment: the base 1 serves as a basic support, and a conveying mechanism 3 is installed in a groove 2 on one side of its upper surface. Multiple rotating shafts 301 rotate within the groove 2, driving the conveying rollers 302 made of alumina-ceramic fiber composite material. This material has strong high-temperature resistance, which can prevent high-temperature metal products from damaging it. The base 1 is also equipped with a fixing plate 4. Through the first hydraulic rod 5 and the second hydraulic rod 7, in conjunction with the connecting plate 6, the position of the clamping mechanism 8 can be flexibly adjusted to accurately clamp and place metal products, and to complete efficient operation in conjunction with the heat treatment component 9.

[0037] In a preferred embodiment, one end of each of the plurality of rotating shafts 301 extends into a groove 2, and two sprockets 303 are fixedly installed on the outside of one end of each rotating shaft 301. The corresponding sprockets 303 on two adjacent rotating shafts 301 are connected by a chain 304 to form a multi-stage chain drive structure.

[0038] In this embodiment, a groove 2 extends from one end of each of the several rotating shafts 301. Two sprockets 303 are fixedly installed on the outside of the extended end of each rotating shaft 301. The corresponding sprockets 303 on two adjacent rotating shafts 301 are tightly meshed and connected by a chain 304, thus forming a multi-stage chain drive structure. This allows power to be transmitted stably and reliably between the rotating shafts 301, ensuring that all conveying rollers 302 can rotate synchronously and at a uniform speed, providing a solid guarantee for the smooth conveying of metal products and effectively improving the stability and reliability of the device operation.

[0039] In a preferred embodiment, a fixing cover 305 is fixedly installed on one side surface of the base 1, and the fixing cover 305 is disposed outside a plurality of chains 304. A first motor 306 is fixedly installed on the surface of the fixing cover 305, and the output end of the first motor 306 is fixedly connected to one end of a rotating shaft 301 on one side.

[0040] In this embodiment: a fixing cover 305 is fixedly installed on one side surface of the base 1 and is set outside several chains 304. It can effectively prevent external dust, debris and other debris from entering the meshing area of ​​the chain 304, avoid wear and transmission failure of the chain 304, and reduce the risk of operators accidentally touching the chain 304, thus ensuring personal safety.

[0041] The first motor 306 is fixed to the surface of the fixed cover 305 by the mounting base and bolts. After the first motor 306 starts, the power is transmitted to the rotating shaft 301, and then through the multi-stage chain drive structure, the rotating shafts 301 rotate synchronously, driving the conveyor roller 302 to run smoothly, realizing reliable conveying of metal products and efficient and stable transmission.

[0042] In a preferred embodiment, the clamping mechanism 8 includes a fixed frame 801, and a threaded rod 802 is rotatably connected inside the fixed frame 801. The thread directions at both ends of the threaded rod 802 are opposite, and clamping plates 803 are threadedly connected to the outside of both ends of the threaded rod 802. Both clamping plates 803 are slidably connected inside the fixed frame 801.

[0043] In this embodiment: the fixed frame 801 of the clamping mechanism 8 provides structural support, and the threads of the threaded rod 802 inside it are opposite at both ends. When the threaded rod 802 rotates, the clamping plates 803 threaded to its two ends will move in opposite directions. Since the two clamping plates 803 are slidably connected within the fixed frame 801, movement can be guaranteed, thereby achieving stable clamping or loosening of metal products of different sizes.

[0044] In a preferred embodiment, a second motor 804 is fixedly mounted on one side surface of the fixed frame 801, and the output end of the second motor 804 is fixedly connected to one end of the threaded rod 802.

[0045] In this embodiment: the second motor 804 serves as a power source, and its output end is stably connected to one end of the threaded rod 802. When the second motor 804 starts running, its output end can drive the threaded rod 802 to rotate.

[0046] In a preferred embodiment, two limiting rods 805 are fixedly installed inside the fixed frame 801, and both clamping plates 803 are slidably connected to the limiting rods 805.

[0047] In this embodiment, two limiting rods 805 are arranged in parallel, and two clamping plates 803 are slidably connected to the limiting rods 805. When the second motor 804 drives the threaded rod 802 to rotate, causing the two clamping plates 803 to move along the axial direction of the threaded rod 802, the limiting rods 805 can effectively restrict the movement trajectory of the clamping plates 803, preventing them from deflecting, swaying or tilting during movement, and ensuring that the two clamping plates 803 always maintain parallel and stable linear movement, thereby achieving precise and reliable clamping of metal products.

[0048] Specifically, the working principle of this solution is as follows:

[0049] A conveying mechanism 3 is installed in the groove 2 on one side of the base 1. When the first motor 306 starts, the power is transmitted to the rotating shaft 301 on one side through the output end. Since the adjacent rotating shafts 301 form a multi-stage chain drive structure through the sprocket 303 and the chain 304, the power can be transmitted stably, so that all rotating shafts 301 rotate synchronously, driving the conveying roller 302 made of high temperature resistant alumina-ceramic fiber composite material to operate, so as to realize the smooth conveying of metal products.

[0050] The first hydraulic rod 5 on the fixed plate 4 and the second hydraulic rod 7 on the connecting plate 6 cooperate to flexibly adjust the position of the clamping mechanism 8. The second motor 804 starts, driving the threaded rod 802 to rotate. Because the threads at both ends of the threaded rod 802 are in opposite directions and are threadedly connected to the clamping plates 803, the two clamping plates 803 move in opposite directions. Simultaneously, the two limiting rods 805 within the fixed frame 801 restrict the movement trajectory of the clamping plates 803, ensuring their parallel and stable movement and achieving precise clamping of the metal product. The metal product is placed on the conveyor roller 302 and conveyed to the heat treatment assembly 9 for heat treatment. After treatment, it is removed by the clamping mechanism 8, completing the entire loading, unloading, and heat treatment process. The device operates stably, reliably, and efficiently.

[0051] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0052] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
