Description

Technical Field

[0001] This utility model relates to the field of metal tube surface heat treatment technology, specifically a metal tube surface heat treatment device. Background Technology

[0002] Currently, heat treatment refers to a metal hot working process that uses heating, holding, and cooling to obtain the desired microstructure and properties of materials in a solid state. Heat treatment is very important in the processing of metal pipe fittings. Compared with other processing techniques, heat treatment generally does not change the shape or overall chemical composition of the workpiece, but rather imparts or improves the workpiece's performance by altering its internal microstructure or surface chemical composition. Heat treatment mainly includes two processes: heating and cooling. Using charcoal and coal as heat sources results in uncontrollable heating temperatures and environmental pollution. Even when electricity is used for heating, the heating effect is poor, the heating time is long, and existing cooling methods are inadequate, with long cooling times and direct heat release, leading to significant waste.

[0003] Application number CN201921117095.X discloses a heat treatment device for metal pipe fittings. By setting up heating tubes, the metal pipe fittings can be rapidly heated. Ventilation pipes allow hot air to be introduced into the heating chamber to rapidly heat the workpieces inside. A rotating motor in the placement device moves the workpieces within the heating chamber, further accelerating the heating process. A first fan re-transports hot air from the cooling chamber to the heating tubes, accelerating the heating time and saving costs. The cooling rails and placement baskets are designed with a mesh structure, effectively increasing the contact area between the air and the workpiece, thus accelerating the cooling or heating speed. An electric slide rail drives a second fan to naturally cool the workpieces within the cooling chamber, further accelerating the cooling process. This utility model has a simple and reasonable structure, is economical and practical, and is easy to use.

[0004] The heat treatment device for metal pipes disclosed in the above patent requires manual feeding and cannot automatically and quantitatively put the metal pipes into the placement basket in the heating box when feeding is required, which wastes manpower. Utility Model Content

[0005] The purpose of this utility model is to provide a metal tube surface heat treatment device. The metal tube surface heat treatment device disclosed in this utility model is equipped with an automatic feeding component at the top feed port. The baffle can be automatically opened before operation to automatically feed the material, saving manpower and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal tube surface heat treatment device, including a heating box, a material box installed on the top of the heating box, the material box including a box shell with a top opening, a material channel integrally connected to the bottom of the box shell through a hopper, a discharge roller rotatably installed at the bottom of the material channel, a plurality of material slots for accommodating metal tubes being opened in a circumferentially equidistant array on the outer side wall of the discharge roller, the power input end of the discharge roller being connected to the power output end of a deceleration rotation drive assembly, and the discharge roller being located vertically above the top inlet of the heating box.

[0007] Preferably, a first gear is locked at the end of the discharge roller, a second gear is meshed with the outer wall of the first gear, and the power input end of the second gear is connected to the power output end of the first motor.

[0008] Preferably, the diameter of the first gear is larger than the diameter of the second gear.

[0009] Preferably, a baffle is slidably connected to the feed inlet at the top of the heating box, and the power input end of the baffle is connected to the power output end of the electric telescopic rod.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see Figures 1-4 The diagram shows a metal tube surface heat treatment device, including a heating chamber 1, a material box 2 installed on the top of the heating chamber 1, the material box 2 including a box shell 201 with a top opening, a material channel 203 integrally connected to the bottom of the box shell 201 through a hopper 202, a discharge roller 13 rotatably installed at the bottom of the material channel 203, the outer wall of the discharge roller 13 having a plurality of material slots 14 that can accommodate metal tubes in a circumferentially equidistant array, the power input end of the discharge roller 13 being connected to the power output end of a speed reduction rotation drive component, the discharge roller 13 being located vertically above the top inlet of the heating chamber 1, the metal tube surface heat treatment device disclosed in this utility model is equipped with an automatic feeding component installed at the top inlet, which can automatically open the baffle 6 before operation and automatically feed the material, saving manpower.

[0021] Furthermore, a first gear 3 is locked at the end of the discharge roller 13, and a second gear 4 is meshed with the outer wall of the first gear 3. The power input end of the second gear 4 is connected to the power output end of the first motor 5 for easy driving. Furthermore, the diameter of the first gear 3 is larger than the diameter of the second gear 4 for easy speed reduction transmission. Furthermore, a baffle 6 is slidably connected at the top feed inlet of the heating box 1, and the power input end of the baffle 6 is connected to the power output end of the electric telescopic rod 7 for easy feeding. Furthermore, a placement basket 11 is rotatably installed on the inner wall of the heating box 1, and the power input end of the placement basket 11 is connected to the power output end of the second motor 12 for easy rotation of the placement basket 11 and the material inside the placement basket 11, so as to ensure uniform heating. Furthermore, a fan 9 is installed at the bottom of the heating box 1, and the air outlet of the fan 9 is connected to the inside of the heating box 1 through the heating pipe 10 and the air outlet pipe 8 for easy heating.

[0022] In this solution, the metal tube surface heat treatment equipment disclosed in this utility model is equipped with an automatic feeding component at the top inlet. Before operation, the baffle 6 is automatically opened, automatically feeding the metal tubes to be treated, saving manpower. The material bin 2 is filled with metal tubes to be treated. When it is necessary to add material to the heating chamber 1, an external power supply is activated, and an external switch controls the electric telescopic rod 7 to shorten, causing the baffle 6 to slide to the right, exposing the top inlet of the heating chamber 1. The external power supply then activates the first motor 5 via an external switch. The first motor 5 drives the second gear 4 to rotate at high speed. Because the outer wall of the second gear 4 is meshed with a larger diameter first gear... 3. The first gear 3 rotates slowly in the opposite direction synchronously, and the discharge roller 13 rotates slowly in the same direction synchronously. During this process, the metal tube falls into the groove on the outer wall of the discharge roller 13 under its own gravity. As the discharge roller 13 rotates, the metal tube in the material trough 14 outside the discharge roller 13 falls from the feed inlet into the placement basket 11 in the heating box 1, which can slowly add material one by one. After the material is added, the motor is turned off, and the electric telescopic rod 7 is driven to extend so that the baffle 6 is reset to block the feed inlet (the first motor 5 is a self-locking motor, and the first motor 5, the second motor 12, the electric telescopic rod 7, the fan 9, the heating tube 10 and the heating box 1 are all existing products on the market).
