Description

Technical Field

[0001] This utility model relates to the field of taper drill bit technology, specifically a heat treatment fixture for taper drill bits. Background Technology

[0002] Currently, tapered drill bits are the core component of rock drilling tools. Tapered drill bits are generally made of high-toughness alloy steel and tungsten carbide alloy. The alloy structure is optimized through the "hot inlay" process to improve drilling efficiency and wear resistance. Tapered drill bits are widely used in secondary crushing, tunnel excavation, and anchor bolt support in mines, and are especially suitable for light drilling operations in medium and soft rock formations.

[0003] Currently, the tooling structure may obstruct the flow of quenching medium, resulting in insufficient cooling rate in local areas of the workpiece, forming soft spots or uneven hardness, which significantly reduces the wear resistance and fatigue strength of the drill bit. Moreover, the tooling material itself needs to be repeatedly heated and cooled, and its ineffective heat loss accounts for a high proportion of the total energy consumption in the pit furnace, significantly increasing production costs.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a heat treatment fixture for a tapered drill bit, comprising:

[0021] A fixed frame 1 is provided, and a main limiting frame 2 is fixedly fitted on the upper surface of the outer wall of the fixed frame 1. A closing plate 3 is fixedly fitted on the bottom of the outer wall of the fixed frame 1. Multiple lifting columns 4 are slidably embedded in the top of the inner wall of the fixed frame 1. A lifting plate 5 is fixedly fitted on the top of the outer wall of the multiple lifting columns 4. The outer wall of the lifting plate 5 is slidably embedded in the main limiting frame 2. A sliding column 6 is fixedly fitted on the bottom of the outer wall of the lifting plate 5. The outer wall of the sliding column 6 is slidably embedded in the fixed frame 1 and the closing plate 3.

[0022] In this implementation scheme: multiple lifting columns 4 are hydraulically driven to abut against the fixed frame 1, thereby driving the lifting plate 5 to rise and slide. The main limiting frame 2 makes the lifting plate 5 more stable in rising and sliding. The lifting plate 5 drives the sliding column 6 to slide within the fixed frame 1 and the closing plate 3. The bottom of the sliding column 6 can be embedded with the drill bit, thereby driving the drill bit into the fixed frame 1.

[0023] Specifically, an electromagnetic control box 7 is installed on one side of the outer wall of the fixed frame 1, and an electromagnetic threaded coil 8 is fixed on one side of the outer wall of the electromagnetic control box 7.

[0024] In this embodiment: under the control of electricity, the electromagnetic control box 7 makes the current pass through the electromagnetic threaded coil 8, and the electromagnetic threaded coil 8 surrounds the drill bit to perform uniform electromagnetic heating treatment on the drill bit.

[0025] Specifically, four reinforcing plates 9 are fixedly installed on the inner wall of the fixed frame 1, and the outer wall of the electromagnetic threaded coil 8 is fixedly embedded between the four reinforcing plates 9.

[0026] In this embodiment, the electromagnetic threaded coil 8 can be stably fixed in the fixed frame 1 by means of four reinforcing plates 9.

[0027] Specifically, a rotating plate 10 is rotatably provided at the bottom of the outer wall of the closing plate 3, and a handle 11 is fixedly provided at the bottom of the outer wall of the rotating plate 10.

[0028] In this embodiment: the handle 11 allows for easy rotation of the rotating plate 10, thereby closing the bottom of the fixed frame 1.

[0029] Specifically, a secondary limiting frame 12 is fixedly provided at the bottom of the outer wall of the closed plate 3, and the outer wall of the rotating plate 10 is slidably embedded between the secondary limiting frame 12 and the closed plate 3.

[0030] In this embodiment, the rotation of the rotating plate 10 is made more stable by the secondary limiting frame 12.

[0031] Specifically, an air exchange box 13 is installed on one side of the outer wall of the fixed frame 1.

[0032] In this embodiment, inert gas can be filled into the fixed frame 1 through the air exchange box 13.

[0033] In use, multiple lifting columns 4 use hydraulic outputs to press against the fixed frame 1, thereby driving the lifting plate 5 to rise and slide. The main limiting frame 2 makes the lifting plate 5 more stable in rising and sliding. The lifting plate 5 drives the sliding column 6 to slide within the fixed frame 1 and the closing plate 3. The bottom of the sliding column 6 can be locked with the drill bit, thereby driving the drill bit into the fixed frame 1. The electromagnetic control box 7, under the control of electricity, makes the current pass through the electromagnetic threaded coil 8. The electromagnetic threaded coil 8 surrounds the drill bit and performs uniform electromagnetic heating treatment on the drill bit. The four reinforcing plates 9 can stably fix the electromagnetic threaded coil 8 within the fixed frame 1. The handle 11 makes it easy to rotate the rotating plate 10 to close the bottom of the fixed frame 1. The secondary limiting frame 12 makes the rotation of the rotating plate 10 more stable. The ventilation box 13 can fill the fixed frame 1 with inert gas. The whole can use electromagnetic heating and be filled with inert gas to prevent oxidation reaction on the surface of the tapered drill bit, thereby improving heating efficiency and reducing changes in the structure of the tapered drill bit.
