Description

Technical Field

[0001] This utility model relates to the field of fixing frame technology, specifically a metal heat treatment processing fixing frame. Background Technology

[0002] Metal heat treatment is an important metal processing technology that involves heating, holding, and cooling metal workpieces in a specific medium to change the surface or internal structure of the metal material, thereby controlling its properties. This process can improve the mechanical properties of metal materials, such as increasing hardness and strength, and enhancing wear resistance and corrosion resistance. Heat treatment is widely used in metallurgy, machinery manufacturing, aerospace, automotive industry and other fields.

[0003] Regarding metal heat treatment processing fixtures, a search revealed that publication number CN218262662U discloses a heat treatment placement rack for metal processing. The beneficial effects of this invention are: through the action of springs, two clamping blocks move relative to each other; simultaneously, when the two springs push one end of each rack, the surfaces on both sides of the gears mesh with one side of each rack, allowing the clamping plates at the top of the two racks to achieve synchronous centering and clamping, fixing both sides of the bottom of the gear blank and improving clamping stability. However, this placement rack has certain drawbacks in actual use. It lacks a moving function, preventing the metal parts to be processed from being moved into the heat treatment chamber. The metal parts must be placed in the rack manually for heat treatment, and after heat treatment, they must also be manually removed from the rack, which is time-consuming and labor-intensive, reducing the efficiency of metal heat treatment processing. Furthermore, the rack and placement plate lack ventilation, resulting in uneven heat dissipation between the placement plate and the rack, leading to uneven heating of the metal parts and slow heat treatment speed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a metal heat treatment processing fixture, which can be moved into the heat treatment box by a movable component to facilitate the heat treatment of metal tubes. After processing, the fixture body can also be easily removed from the heat treatment box, achieving the purpose of saving time and effort and improving the working efficiency of metal heat treatment processing. Through the setting of the opening and the ventilation mesh, heat can flow between the fixture body and the three placement plates, ensuring that the placed metal tubes are heated evenly, thereby accelerating the heat treatment speed of the metal tubes.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A metal heat treatment processing fixture includes: a heat treatment chamber, a fixture body disposed inside the heat treatment chamber, three placement plates installed inside the fixture body, and a moving component disposed at the bottom of the fixture body. The moving component includes: steel wheels, wheel seats, brake pedals, and moving grooves, all of which are provided with multiple openings at the bottom of the fixture body and the three placement plates, and a ventilated mesh installed inside the multiple openings.

[0007] Preferably, the bottom of the fixed frame body is provided with steel wheels on four sides, and wheel seats are installed between the steel wheels and the fixed frame body. A brake pedal is movably connected to the outer end of the wheel seat, and two moving grooves are opened at the bottom of the inside of the heat treatment box.

[0008] Preferably, multiple arc-shaped limiting blocks are fixedly installed on both sides of the top of the three placement plates, and limiting rods are threadedly connected to the top sides of the multiple arc-shaped limiting blocks. Two iron pressure plates are provided on the top of the placement plates, and a connecting block is fixedly installed between the two iron pressure plates by bolts. Multiple arc-shaped pressure blocks are fixedly installed on the bottom of the two iron pressure plates. Through holes are opened on both sides of the bottom of the multiple arc-shaped pressure blocks and on the top of the iron pressure plates. Movable openings are opened on both sides of the outer end of the fixing frame body, and the two ends of the iron pressure plates are located inside the movable openings.

[0009] Preferably, inclined pads are fixedly installed at the outer ends of the two movable grooves, and the surface of the inclined pads is provided with anti-slip stripes.

[0010] Preferably, limiting grooves are provided on both sides inside the two moving grooves, and a locking block is fixed between the two limiting grooves.

[0011] Preferably, a heating chamber is installed at the top inside the heat treatment chamber, a heating block is installed inside the heating chamber, temperature sensors are installed on both sides inside the heat treatment chamber, a door is rotatably connected to the outside of the heat treatment chamber via a hinge, and a control panel is installed on the outside of the door.

[0012] Preferably, sealing blocks are fixedly installed on both sides of the bottom of the box door.

[0013] The beneficial effects of this utility model are:

[0014] (1) The movable component of this utility model can move the fixed frame body into the heat treatment box for easy heat treatment of metal tubes. After the heat treatment is completed, the fixed frame body can be moved out of the heat treatment box, thus saving time and effort and improving the working efficiency of heat treatment of metal parts. The setting of the opening and the ventilation mesh ensures that there is heat flow between the fixed frame body and the three placement plates, ensuring that the placed metal tubes are heated evenly, thereby accelerating the heat treatment speed of the metal tubes.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figures 1-8As shown, a metal heat treatment processing fixture includes: a heat treatment box 1, a fixture body 2 disposed inside the heat treatment box 1, three placement plates 201 installed inside the fixture body 2, and a moving component disposed at the bottom of the fixture body 2. The moving component includes: steel wheels 3, wheel seats 301, brake pedals 302, and moving grooves 303, all of which are provided with multiple openings 4 at the bottom of the fixture body 2 and the three placement plates 201, and a ventilated mesh 401 installed inside the multiple openings 4.

[0028] Among them, multiple arc-shaped limiting blocks 202 are fixedly installed on both sides of the top of the three placement plates 201. Limiting rods 203 are threadedly connected to the top sides of the multiple arc-shaped limiting blocks 202. Two iron pressure plates 204 are provided on the top of the placement plates 201. A connecting block is fixedly installed between the two iron pressure plates 204 by bolts. Multiple arc-shaped pressure blocks 205 are fixedly installed at the bottom of the two iron pressure plates 204. Through holes 206 are opened on both sides of the bottom of the multiple arc-shaped pressure blocks 205 and the top of the iron pressure plates 204. Movable openings 207 are opened on both sides of the outer end of the fixing frame body 2. The two ends of the iron pressure plates 204 are located inside the movable openings 207.

[0029] When placing the metal pipe inside the fixing frame body 2, the worker uses their hands to grasp the connecting blocks on both sides of the outer end of the fixing frame body 2 and lifts up the two iron pressure plates 204. The two iron pressure plates 204 move upward within the movable opening 207, causing multiple arc-shaped pressure blocks 205 to move upward, thus widening the gap between the arc-shaped pressure blocks 205 and the arc-shaped limiting blocks 202. Then, the worker picks up the metal pipe and places it in the corresponding arc-shaped limiting block 202, and then slowly lowers the connecting block, so that the two iron pressure plates 204 and the multiple arc-shaped pressure blocks... Block 205 slides downward through the through hole 206 at the limiting rod 203, that is, the arc-shaped pressure block 205 presses against the top of the metal tube. Since the iron pressure plate 204 and the arc-shaped pressure block 205 are both made of iron and have weight, the center of gravity of the iron pressure plate 204 and the arc-shaped pressure block 205 is downward, which can press and fix both ends of the metal tube on the placement plate 201 to prevent the metal tube from shaking. Moreover, the position of the iron pressure plate 204 and the arc-shaped pressure block 205 is limited by the limiting rod 203, which increases the pressing force on the metal tube.

[0030] The fixed frame body 2 has steel wheels 3 on its four sides at the bottom. A wheel seat 301 is installed between the steel wheels 3 and the fixed frame body 2. A brake pedal 302 is movably connected to the outer end of the wheel seat 301. Two moving grooves 303 are opened at the bottom of the heat treatment box 1. After the metal tube is placed inside the fixed frame body 2, the box door 6 on the outside of the heat treatment box 1 is opened. The fixed frame body 2 is pushed so that the steel wheels 3 at the bottom are moved under force. The fixed frame body 2 can be moved to the outside of the heat treatment box 1. The steel wheels 3 are aligned with the two moving grooves 303 at the bottom of the heat treatment box 1. The fixed frame body 2 is pushed so that the steel wheels 3 are moved into the moving grooves 303. The fixed frame body 2 is moved into the heat treatment box 1 for placement, which is convenient for heat treatment of the metal tube. After processing, it is also convenient to remove the fixed frame body 2 from the heat treatment box 1, which saves time and effort and improves the working efficiency of heat treatment of metal parts.

[0031] Among them, the two moving grooves 303 have limit grooves 305 on both sides inside. The two limit grooves 305 are locked together and fixed with a locking block 306. After the steel wheel 3 moves into the moving groove 303, the steel wheel 3 is locked by the brake pedal 302. Then the locking block 306 is locked in the two limit grooves 305 to limit the placement of the steel wheel 3, prevent the steel wheel 3 from moving again, and avoid causing the fixed frame body 2 to move and impact the box door 6.

[0032] The heat treatment chamber 1 has a heating chamber 5 installed at the top inside, a heating block 501 installed inside the heating chamber 5, and temperature sensors 502 installed on both sides inside the heat treatment chamber 1. A door 6 is hinged to the outside of the heat treatment chamber 1, and a control panel 601 is installed on the outside of the door 6. After the mounting bracket 2 moves into the heat treatment chamber 1 and locks the steel wheels 3, the door 6 closes, sealing the inside of the heat treatment chamber 1. The temperature sensors 502 and the heating block 501 are connected to the control panel 601 via wires. A power cord connected to the control panel 601 is installed on the outside of the heat treatment chamber 1, and a plug is installed at the outer end of the power cord, which is inserted into an external socket. When the power is turned on, the control panel 601, temperature sensor 502, and heating block 501 are powered on and put into normal use. The temperature sensor 502 and heating block 501 are activated through the control panel 601. After the heating block 501 is activated, the heat generated is distributed inside the heat treatment chamber 1 to raise the temperature and perform heat treatment processing on the metal tube placed inside the fixing frame body 2, improving the mechanical properties of the metal tube and enhancing its wear resistance and corrosion resistance. During the heating process, the temperature sensor 502 detects the internal temperature of the heat treatment chamber 1, and the detected information is transmitted to the control panel 601 through an electrical signal. The operator can see the temperature value on the display screen of the control panel 601.

[0033] During the heat treatment of the metal tube, the bottom of the fixing frame body 2 and the three placement plates 201 are provided with openings 4 and ventilation mesh 401, so that heat can flow between the fixing frame body 2 and the three placement plates 201, ensuring that the placed metal tube is heated evenly, thereby accelerating the heat treatment speed of the metal tube. After the heat treatment is completed, the box door 6 is opened, the locking block 306 is pulled out from the limiting groove 305, and the brake pedal 302 is pulled up to release the steel wheel 3 from locking. The fixing frame body 2 is pulled so that the steel wheel 3 rolls out from the moving groove 303, thereby moving the fixing frame body 2 out of the heat treatment box 1, so that the heat-treated metal tube can be unloaded from the inside of the fixing frame body 2.

[0034] The temperature sensor 502, model number WZP-291, works as follows: It generally consists of three parts: a temperature-sensitive element, a conversion element, and a temperature conversion circuit. The function of the temperature-sensitive element is to convert the sensed temperature signal into a measurable quantity that is related to the temperature. The function of the conversion element is to convert the physical quantity output by the temperature-sensitive element into an electrical quantity. The function of the conversion circuit is to convert the electrical quantity output by the conversion element into a measurable electrical quantity, such as voltage, current, or frequency. The temperature sensor 502 is a mature and conventional technology in this field, and this solution does not improve the circuit or program of the temperature sensor 502. The circuit and signal connection between the temperature sensor 502 and the control panel 601 are also common and conventional technologies; therefore, their circuit and signal connection relationships will not be elaborated upon.

[0035] Among them, sealing blocks 7 are fixedly installed on both sides of the bottom of the box door 6. When the box door 6 is closed, since the width and diameter of the sealing blocks 7 are the same as those of the moving grooves 303, the two sealing blocks 7 fit into the inner walls of the two moving grooves 303, and the bottom ends of the two sealing blocks 7 contact the inclined pads 304, thereby sealing the moving grooves 303 and preventing the heat inside the heat treatment box 1 from being lost.

[0036] Among them, inclined pads 304 are fixedly installed at the outer ends of the two moving grooves 303. The surface of the inclined pads 304 is provided with anti-slip stripes. When the steel wheel 3 is pushed into the moving groove 303 and rolled out of the moving groove 303, the inclined pads 304 facilitate the movement of the steel wheel 3 out of the heat treatment box 1, avoid impact on the steel wheel 3, and prevent the steel wheel 3 from slipping through the anti-slip stripes.

[0037] Working principle:

[0038] When placing the metal pipe inside the fixing frame body 2, the worker uses their hands to grasp the connecting blocks on both sides of the outer end of the fixing frame body 2 and lifts up the two iron pressure plates 204. The two iron pressure plates 204 move upward within the movable opening 207, causing multiple arc-shaped pressure blocks 205 to move upward, thus widening the gap between the arc-shaped pressure blocks 205 and the arc-shaped limiting blocks 202. Then, the worker picks up the metal pipe and places it in the corresponding arc-shaped limiting block 202, and then slowly lowers the connecting block, so that the two iron pressure plates 204 and the multiple arc-shaped pressure blocks... Block 205 slides downward through the through hole 206 at the limiting rod 203, that is, the arc-shaped pressure block 205 presses against the top of the metal tube. Since the iron pressure plate 204 and the arc-shaped pressure block 205 are both made of iron and have weight, the center of gravity of the iron pressure plate 204 and the arc-shaped pressure block 205 is downward, which can press and fix both ends of the metal tube on the placement plate 201 to prevent the metal tube from shaking. Moreover, the position of the iron pressure plate 204 and the arc-shaped pressure block 205 is limited by the limiting rod 203, which increases the pressing force on the metal tube.

[0039] After placing the metal tube inside the mounting bracket 2, open the outer door 6 of the heat treatment chamber 1, push the mounting bracket 2 so that the steel wheels 3 at its bottom are moved under force, and move the mounting bracket 2 to the outside of the heat treatment chamber 1. Align the steel wheels 3 with the two moving grooves 303 at the bottom of the heat treatment chamber 1, push the mounting bracket 2 so that the steel wheels 3 move into the moving grooves 303, and move the mounting bracket 2 into the heat treatment chamber 1 for placement. This facilitates the heat treatment of the metal tube. After processing, it is also easy to remove the mounting bracket 2 from the heat treatment chamber 1, achieving the purpose of saving time and effort and improving the working efficiency of metal heat treatment processing.

[0040] When the door 6 is closed, since the width and diameter of the sealing block 7 and the moving groove 303 are the same, both sealing blocks 7 fit into the inner walls of the two moving grooves 303, and the bottom of the two sealing blocks 7 contacts the inclined pad 304, thereby sealing the moving groove 303 and preventing heat loss from the inside of the heat treatment box 1.
