Description

Technical Field

[0001] This utility model relates to the field of alloy processing technology, specifically a hot air circulation device for cemented carbide processing. Background Technology

[0002] Hard alloy is an alloy material made from hard compounds of refractory metals and binder metals through powder metallurgy. Hard alloys possess a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance.

[0003] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: the existing hot air circulation equipment for cemented carbide processing mostly has an opening and door on one side. Whenever the alloy workpiece is changed, the door needs to be opened, during which a large amount of heat is lost, indirectly affecting the heat treatment efficiency. It is urgent to improve it. Therefore, we propose a hot air circulation equipment for cemented carbide processing. Utility Model Content

[0004] The purpose of this invention is to provide a hot air circulation device for cemented carbide processing, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hot air circulation device for cemented carbide processing, comprising a housing, a baffle plate placed on one side of the housing, a hot air blower body fixedly installed on the upper surface of the housing, and air pipes connected to one side of both the housing and the hot air blower body;

[0006] An opening is provided on the side of the housing closest to the baffle, a groove is provided on the inner wall of the housing away from the opening, and a storage battery is fixedly installed on the outer wall of the housing near the groove.

[0007] The inner wall of the bottom of the housing is provided with a sliding groove, and a slider is movably locked in one side of the sliding groove;

[0008] A movable plate is movably inserted into the opening, and the movable plate is fixedly connected to the baffle. The shape of the movable plate is adapted to the contour of the opening. The bottom of the movable plate is fixedly connected to the slider. A sealing gasket is fixedly installed on the inner surface of the baffle.

[0009] The upper surface of the movable plate is provided with several sets of uniformly arranged storage slots, and a tray is placed at the bottom of each storage slot.

[0010] Both sets of tracheas are fitted with flexible tubes on the outside, and the flexible tubes are fixed to the tracheas by clamps;

[0011] The hot air blower body has air outlets installed on the pipes on both sides of its bottom. It can be used in conjunction with components such as openings, movable plates, and storage tanks. During the use of the hot air circulation equipment, after each batch of alloy workpieces has been hot-air treated, the baffle can be moved outward by applying force. The baffle can drive the movable plate through the opening. Since the shape of the movable plate is adapted to the opening, when the movable plate is completely moved outward, it can block the opening. This reduces the loss of heat inside the shell during the loading and unloading of alloy workpieces, and indirectly improves the heat treatment efficiency of the equipment.

[0012] As an optional solution to the technical solution of this application, a micro switch is fixedly installed in the groove. The battery is electrically connected to the micro switch through a wire, and the micro switch is electrically connected to the hot air blower body through a wire. The micro switch and the battery can be used together. Each time the movable plate is moved outward to replace a part, the outward movement of the movable plate will no longer press the movable button of the micro switch. At this time, the battery is de-energized and the hot air blower stops. Conversely, when the movable plate is pushed back, the hot air blower can be started again. This structure can eliminate the manual start and stop procedure of the hot air blower, which is convenient and quick, and the use effect is quite ideal.

[0013] As an optional solution to the technical solution of this application, ear plates are fixedly installed at the four corners of the bottom of the housing, and a positioning hole is opened in the middle of the ear plate. Through the positioning hole of the ear plate, the bolt can be moved through and screwed into the pre-set threaded structure on the support, so as to realize the detachable and stable positioning of the equipment.

[0014] As an optional solution to the technical solution of this application, the housing has a wire hole on the side near the groove, and a rubber ring is fixedly installed in the wire hole. The wire can pass through the wire hole for connecting the wires of the internal and external components, and the rubber ring can prevent the wire from being worn and damaged, thus playing a protective role.

[0015] As an optional solution to the technical solution of this application, the tray is located in the storage slot, and clamping blocks are fixedly installed on both sides of the upper surface of the tray. Whenever the shape of the alloy workpiece is too difficult to remove, the clamping blocks can be clamped by external tools and the tray can be pulled up to facilitate the removal of part of the alloy workpiece.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model discloses a hot air circulation device for cemented carbide processing. By providing an opening, a movable plate, and a storage tank, during the use of the hot air circulation device, after each batch of alloy workpieces has been hot-air treated, the baffle can be moved outward by applying force. The baffle can drive the movable plate through the opening. Since the shape of the movable plate is adapted to the opening, when the movable plate is completely moved outward, it can block the opening. Therefore, during the loading and unloading of alloy workpieces, the heat loss inside the shell can be reduced, indirectly improving the heat treatment efficiency of the equipment.

[0018] 2. This utility model discloses a hot air circulation device for cemented carbide processing. By setting up a micro switch and a storage battery, each time the movable plate is moved outward to change parts, the movement of the movable plate will no longer press the movable button of the micro switch, at which time the storage battery will be de-energized and the hot air blower will stop. Conversely, when the movable plate is pushed back, the hot air blower can be started again. This structure can eliminate the manual start and stop procedure of the hot air blower, which is convenient and quick, and the use effect is quite ideal. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-3This utility model provides a technical solution: a hot air circulation device for cemented carbide processing, including a housing 1. Ear plates 11 are fixedly installed at the four corners of the bottom of the housing 1, and positioning holes are provided in the center of the ear plates 11. Bolts can be movably passed through the positioning holes of the ear plates 11 and screwed onto a pre-set threaded structure on a support, achieving detachable and stable positioning of the device. A baffle 2 is placed on one side of the housing 1. A hot air blower body 5 is fixedly installed on the upper surface of the housing 1. Air pipes 4 are connected to both the housing 1 and the hot air blower body 5 on one side. An opening 12 is provided on the side of the housing 1 closest to the baffle 2. A groove 13 is provided on the inner wall of the housing 1 away from the opening 12. A wire hole 14 is provided on the side of the housing 1 closest to the groove 13, and a rubber ring is fixedly installed in the wire hole 14. A conductive wire can be passed through the wire hole 14 for connecting the wires of internal and external components. The rubber ring prevents wear and damage to the wires, providing protection. The outer wall of the housing 1 is near the groove. A battery 16 is fixedly installed on one side of the housing 1; a groove 3 is provided on the inner wall of the bottom of the housing 1, and a slider 31 is movably positioned on one side of the groove 3; a movable plate 22 is movably inserted into the opening 12, and the movable plate 22 is fixedly connected to the baffle 2. The shape of the movable plate 22 is adapted to the contour of the opening 12, and the bottom of the movable plate 22 is fixedly connected to the slider 31. A sealing gasket 21 is fixedly installed on the inner surface of the baffle 2; several sets of uniformly arranged storage slots 23 are provided on the upper surface of the movable plate 22. A tray 25 is placed at the bottom of the storage tank 23. The tray 25 is located inside the storage tank 23, and clamps 24 are fixedly installed on both sides of the upper surface of the tray 25. Whenever the shape of the alloy workpiece is too difficult to remove, the clamps 24 can be clamped by external tools and the tray 25 can be pulled up to facilitate the removal of part of the alloy workpiece. The two sets of air pipes 4 are fitted with hoses 41 on the outside, and the hoses 41 are fixed to the air pipes 4 by clamps 42. The air outlets 51 are connected to the pipes on both sides of the bottom of the hot air blower body 5.

[0026] In this technical solution, components such as opening 12, movable plate 22, and storage tank 23 can be used together. During the use of the hot air circulation equipment, after each batch of alloy workpieces has been hot-air treated, the baffle 2 can be moved outward by applying force. The baffle 2 can drive the movable plate 22 through the opening 12. Since the shape of the movable plate 22 is adapted to the opening 12, when the movable plate 22 is completely moved outward, the movable plate 22 can block the opening 12. Therefore, during the loading and unloading of alloy workpieces, the loss of heat inside the shell can be reduced, which indirectly improves the heat treatment efficiency of the equipment.

[0027] In some technical solutions, a micro switch 15 is fixedly installed in the groove 13, and the battery 16 is electrically connected to the micro switch 15 through a wire. The micro switch 15 is electrically connected to the hot air blower body 5 through a wire.

[0028] In this technical solution, components such as micro switch 15 and battery 16 can be used together. Each time the movable plate 22 is moved outward to replace a part, the outward movement of the movable plate 22 will no longer press the movable button of the micro switch 15. At this time, the battery 16 will be de-energized and the hot air blower will stop. Conversely, when the movable plate 22 is pushed back, the hot air blower can be started again. This structure can eliminate the manual start and stop procedure of the hot air blower, which is convenient and quick, and the use effect is quite ideal.

[0029] Working principle: It should be noted that this utility model is a hot air circulation device for cemented carbide processing. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0030] When using a hot air circulation device for cemented carbide processing, the hot air circulation device is placed in the cemented carbide processing area, the device is fixed by the ear plate 11, and the alloy workpiece is placed in the storage tank 23 for hot air treatment.

[0031] With an opening 12, a movable plate 22, and a storage slot 23, during the use of the hot air circulation equipment, after each batch of alloy workpieces has been hot-air treated, the baffle 2 can be moved outward by applying force. The baffle 2 can drive the movable plate 22 through the opening 12. Since the shape of the movable plate 22 is adapted to the opening 12, when the movable plate 22 is completely moved outward, it can block the opening 12. This reduces the loss of heat inside the housing during the loading and unloading of alloy workpieces, indirectly improving the heat treatment efficiency of the equipment. With a micro switch 15 and a battery 16, each time the movable plate 22 is moved outward for workpiece replacement, the outward movement of the movable plate 22 will no longer press the movable button of the micro switch 15. At this time, the battery 16 will be de-energized, and the hot air blower will stop operating. Conversely, when the movable plate 22 is pushed back, the hot air blower can be restarted. This structure eliminates the need for manual start and stop of the hot air blower, making it convenient and quick, and the effect is quite ideal.
