A heat treatment apparatus for machining

Abstract

This utility model discloses a heat treatment equipment for machining, including a heating equipment body and heat dissipation windows. The heating equipment body has heat dissipation windows symmetrically opened on both sides of the casing, and also includes a heat dissipation mechanism. By setting the heat dissipation mechanism on the outside of the heating equipment body, the U-shaped drawer of the heat dissipation mechanism can cover the outside of the heating equipment body. A cooling fan is located at the top window slot of the heating equipment body and accelerates the downward blowing into the heating equipment body at the middle waist top cover seat, so that the heat inside the heating equipment body can be efficiently discharged from the heat dissipation windows. At the same time, the middle waist side cover seat at the U-shaped drawer accelerates and guides the air force through the rib plate to disperse it, thereby efficiently carrying away the hot air discharged from the heat dissipation windows. This can effectively prevent the power devices inside the heating equipment body from aging or even burning out due to overheating, and ensure the stable operation of the medium frequency induction heating equipment during the machining heat treatment process.

Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, and in particular to a heat treatment equipment for machining. Background Technology

[0002] Heat treatment refers to a metal heat treatment process in which materials, in their solid state, are heated, held at temperature, and cooled to obtain the desired microstructure and properties. In machining, heat treatment is a crucial step, as it can alter the internal structure of materials to improve their mechanical properties, enhance product performance, and extend service life. Among heat treatment equipment, medium-frequency induction heating devices are used in machining heat treatment. The principle of medium-frequency induction heating for machining heat treatment is based on Faraday's law of electromagnetic induction and the Joule heating effect. A medium-frequency power supply powers an induction coil, creating an alternating magnetic field around the coil. When a metal workpiece is placed in this alternating magnetic field, eddy currents are induced inside the workpiece according to Faraday's law of electromagnetic induction. Due to the resistance of the metal, as these eddy currents flow inside the workpiece, the Joule heating effect directly converts electrical energy into heat energy, causing the workpiece to rapidly heat up and complete the heat treatment.

[0003] In existing medium-frequency induction heating equipment, workers clamp the workpiece and place it inside the coil for heat treatment during machining. When the medium-frequency induction heating equipment is working, a large amount of heat is generated inside the machine due to the current heating effect and power conversion loss. However, the machine is usually cooled by air, which is a simple way to dissipate heat. This method has limited heat dissipation effect and can easily cause the power devices inside the machine to overheat, age, or even burn out. Therefore, we propose a heat treatment equipment for machining. Utility Model Content

[0004] The main objective of this invention is to provide a heat treatment device for machining. By setting a heat dissipation mechanism on the outside of the heating device body, the U-shaped drawer of the heat dissipation mechanism can cover the outside of the heating device body. A cooling fan with a top opening slot on the heating device body accelerates the downward blowing into the heating device body from the middle top cover seat, so that the heat inside the heating device body can be efficiently discharged from the heat dissipation window. At the same time, the middle side cover seat of the U-shaped drawer accelerates and guides the air force through the rib plate to disperse it, thereby efficiently carrying away the hot air discharged from the heat dissipation window. This can effectively prevent the power devices inside the heating device body from aging or even burning out due to overheating, and ensure the stable operation of the medium frequency induction heating equipment during the machining heat treatment process. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A heat treatment device for machining includes a heating device body and heat dissipation windows. The heating device body has symmetrically arranged heat dissipation windows on both sides of its casing. It also includes a heat dissipation mechanism, which comprises a bridge plate, a U-shaped drawer cover, a top window groove, four corner support plates, a central top cover seat, a central side cover seat, and a cooling fan. The top of the heating device body is symmetrically equipped with bridge plates, and U-shaped drawer covers covering the heat dissipation windows are symmetrically welded below the bridge plates. The side drawer panels of the U-shaped drawer cover have drawer openings, and a central side cover seat is welded to the surface of the U-shaped drawer cover outside the drawer opening. Dividing ribs are welded inwards from the drawer openings into the U-shaped drawer cover. A top window groove for ventilation is formed on the surface of the heating device body between the bridge plates. Four corner support plates are welded to the top of the heating device body outside the top window groove, and a central top cover seat is fitted onto the outer side of the four corner support plates. A cooling fan is installed at the outer opening of the central top cover seat and the central side cover seat.

[0007] Furthermore, the middle waist top cover and the middle waist side cover are recessed in the outer seat opening near the cooling fan, and dustproof frame cotton is installed in the recessed groove of the middle waist top cover and the middle waist side cover.

[0008] By adopting the above technical solution, the dustproof frame cotton can be installed in the concave groove of the top cover seat and the side cover seat. As the cooling fan is installed in the top cover seat and the side cover seat, the dustproof frame cotton can be pressed tightly, making it difficult for dust to enter the top cover seat and the side cover seat.

[0009] Furthermore, mounting holes are provided on the outer body of the top cover and the side cover of the middle waist, and bolts are screwed between the mounting holes of the top cover and the side cover of the middle waist and the housing of the cooling fan.

[0010] By adopting the above technical solution, the mounting holes of the mid-waist top cover and the mid-waist side cover are installed with the housing of the cooling fan by bolt locking.

[0011] Furthermore, four sets of the dividing stiffeners are symmetrically welded at the drawer opening, and the dividing stiffeners spread out from the drawer opening into the U-shaped drawer cover.

[0012] By adopting the above technical solution, the U-shaped drawer cover can divert and guide the airflow at the drawer opening towards the heat dissipation window, so that the heat emitted from the heating equipment body can be smoothly carried away from the heat dissipation window.

[0013] Furthermore, the U-shaped drawer cover has a side air vent located away from the drawer opening, and the U-shaped drawer cover is clamped to both sides of the casing of the heating equipment body.

[0014] By adopting the above technical solution, after the U-shaped drawer is placed on both sides of the heating equipment body, the U-shaped drawer can guide the air force to be discharged from the side air vents.

[0015] Furthermore, the seat of the middle waist top cover and the middle waist side cover are double-ended large-headed seats, and a constricted waist seat is provided in the middle of the seat of the middle waist top cover and the middle waist side cover.

[0016] By adopting the above technical solution, the double-ended large-head seat body of the middle waist top cover and the middle waist side cover, together with the waist seat body that shrinks in the middle, can increase the airflow speed when passing through, thereby ensuring that the air force enters the heating equipment body and the U-shaped drawer at high speed.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a heat dissipation mechanism on the outside of the heating device body. The U-shaped drawer of the heat dissipation mechanism can cover the outside of the heating device body. A cooling fan at the top window slot of the heating device body accelerates the downward blowing into the heating device body at the middle waist top cover seat, so that the heat inside the heating device body can be efficiently discharged from the heat dissipation window. At the same time, the middle waist side cover seat at the U-shaped drawer accelerates and guides the air force through the rib plate to disperse it, thereby efficiently carrying away the hot air discharged from the heat dissipation window. This can effectively prevent the power devices inside the heating device body from aging or even burning out due to overheating, and ensure the stable operation of the medium frequency induction heating equipment during mechanical processing and heat treatment.

[0019] Furthermore, the top and side covers of the middle waist are fitted with dustproof frame cotton through recessed grooves, which can press the dustproof frame cotton tightly during the installation of the cooling fan, greatly reducing the probability of dust entering the interior of the heating equipment.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-4 As shown, a heat treatment device for machining includes a heating device body 1 and heat dissipation windows 2. The heating device body 1 has heat dissipation windows 2 symmetrically arranged on both sides of its casing. It also includes a heat dissipation mechanism 3, which includes a bridge plate 4, a U-shaped drawer cover 5, a top window slot 8, four corner support plates 9, a central top cover seat 10, a central side cover seat 11, and a cooling fan 13. The bridge plate 4 is symmetrically installed at the top of the heating device body 1, and U-shaped drawer covers 5 are symmetrically welded below the bridge plate 4, covering the outside of the heat dissipation windows 2. A drawer opening 6 is provided on the side drawer panel of the drawer cover 5, and a middle waist side cover seat 11 is welded to the surface of the U-shaped drawer cover 5 outside the drawer opening 6. Dividing ribs 7 are arranged and welded inward from the drawer opening 6 into the U-shaped drawer cover 5, and a top opening window groove 8 for ventilation is provided on the surface of the heating equipment body 1 between the bridge plates 4. Four corner support plates 9 are welded to the top of the heating equipment body 1 outside the top opening window groove 8, and a middle waist top cover seat 10 is clamped on the outside of the four corner support plates 9. A cooling fan 13 is installed at the outer seat opening of the middle waist top cover seat 10 and the middle waist side cover seat 11.

[0027] Among them, the middle waist top cover 10 and the middle waist side cover 11 are provided with recessed stepped grooves in the outer seat openings near the cooling fan 13, and dustproof frame cotton 12 is installed in the recessed stepped grooves of the middle waist top cover 10 and the middle waist side cover 11.

[0028] By adopting the above technical solution, the dustproof frame cotton 12 can be installed in the concave groove of the middle waist top cover 10 and the middle waist side cover 11. With the cooling fan 13 installed in the middle waist top cover 10 and the middle waist side cover 11, the dustproof frame cotton 12 can be pressed tightly, so that the middle waist top cover 10 and the middle waist side cover 11 are not easy to enter dust.

[0029] The middle waist top cover 10 and the middle waist side cover 11 are provided with mounting holes on their outer seats, and bolts are screwed between the mounting holes of the middle waist top cover 10 and the middle waist side cover 11 and the housing of the cooling fan 13.

[0030] By adopting the above technical solution, the mounting holes of the mid-waist top cover 10 and the mid-waist side cover 11 are installed with the housing of the cooling fan 13 by bolt locking.

[0031] Among them, four sets of the dividing stiffening plates 7 are symmetrically welded at the drawer opening 6, and the dividing stiffening plates 7 spread out from the drawer opening 6 into the U-shaped drawer cover 5.

[0032] By adopting the above technical solution, the U-shaped drawer cover 5 can use the splitting ribs 7 to divert and guide the airflow at the drawer opening 6 towards the heat dissipation window 2, so that the heat emitted from the heating equipment body 1 can be smoothly carried away from the heat dissipation window 2.

[0033] The U-shaped drawer cover 5 is provided with a side air vent at the cover body away from the drawer opening 6, and the U-shaped drawer cover 5 is clamped on both sides of the casing of the heating equipment body 1.

[0034] By adopting the above technical solution, after the U-shaped drawer cover 5 covers both sides of the heating equipment body 1, the air force can be guided out from the side air vent at the U-shaped drawer cover 5.

[0035] The seat of the middle waist top cover 10 and the middle waist side cover 11 is a double-ended large-head seat, and a constricted waist seat is provided in the middle of the seat of the middle waist top cover 10 and the middle waist side cover 11.

[0036] By adopting the above technical solution, the double-ended large-head seat body of the middle waist top cover 10 and the middle waist side cover 11, together with the waist seat body that shrinks in the middle, can increase the airflow speed when passing through, thereby ensuring that the wind enters the heating equipment body 1 and the U-shaped drawer 5 at high speed.

[0037] It should be noted that this utility model is a heat treatment equipment for machining. By setting a heat dissipation mechanism 3 at the heating equipment body 1 for machining, and symmetrically covering the U-shaped drawer 5 of the heat dissipation mechanism 3 on both sides of the heating equipment body 1, the bridge plate 4 between the U-shaped drawer 5 can be locked to the heating equipment body 1 with bolts. Then, dustproof frame cotton 12 can be installed in the middle waist top cover seat 10 and the middle waist side cover seat 11, and the cooling fan 13 is installed by bolts. The middle waist top cover seat 10 can be covered at the four corner support plates 9 outside the top opening window groove 8. The cooling fan 13 can be connected to power and controlled as needed by an external controller under the guidance of professional electrical technicians.

[0038] When the heating equipment body 1 is powered on for heat treatment of workpieces in machining, the cooling fan 13 can be turned on. The air blown in from the middle waist top cover 10 is accelerated and blown into the heating equipment body 1 along the top opening window groove 8. The heat inside the heating equipment body 1 is carried out of the heat dissipation window 2 by the air force. Then, the air force at the middle waist side cover 11 is accelerated and blown to the outside of the heating equipment body 1 after being diverted by the splitting rib plate 7. At this time, the air force blown out from the heat dissipation window 2 is accelerated and carried away, realizing the efficient discharge of heat inside the heating equipment body 1. The dustproof frame cotton 12 can be a dustproof component composed of a metal frame with dustproof cotton glued inside, which is convenient for its installation.

[0039] It should be noted that this utility model is a heat treatment equipment for machining. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
