Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, and specifically relates to a surface heat treatment device for metal processing. Background Art

[0002] The heat treatment of metals, namely quenching in traditional understanding, can improve the compressive and wear-resistant properties of metal materials, and they will not rust or corrode easily. It is necessary to first heat metal plates, metal blocks, etc. to a certain temperature, and then quickly put them into a water tank for cooling when the temperature reaches the critical value to harden the surface of the metal.

[0003] Most ordinary such processing devices separate heating and cooling into two non-connected entities. If connection is necessary, it is difficult to keep the heating space airtight. The flame sprayed by the spray gun is difficult to accumulate high temperature, which not only consumes fuel but also is quite inconvenient when entering and leaving the device.

[0004] Now, a new type of surface heat treatment device for metal processing is proposed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a surface heat treatment device for metal processing to solve the problem of poor linkage of the device proposed in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A surface heat treatment device for metal processing, including a substrate and a heating frame. The heating frame is installed on the left side of the top of the substrate, and through slots one are respectively arranged at the centers of both sides of the heating frame. Brackets are respectively welded on both sides of the outer top of the heating frame, and a motor is installed outside the brackets. A bevel gear one is fixed on the output end of the motor. On both sides of the upper part inside the heating frame, lead screws are respectively movably connected, and a bevel gear two is fixed at the top of the lead screw. A threaded cylinder is sleeved outside the lead screw. A sealing plate is welded at the bottom of the threaded cylinder, and a slider is welded above the side surface of the sealing plate. Chutes are respectively arranged above the left and right sides inside the heating frame. Two groups of flame spray guns are fixed on the top of the heating frame. A water tank is installed on the right side of the top of the substrate, and through slots two are respectively arranged inside the upper parts on both sides of the water tank. A top plate is lapped on the top of the water tank.

[0007] Preferably, the slider is embedded inside the chute, and the slider can vertically lift along the chute.

[0008] Preferably, the bevel gear one is meshed and connected to the side surface of the top of the bevel gear two, and the bottom of the bevel gear two is movably connected to the surface of the heating frame.

[0009] Preferably, the thread pattern on the outer wall of the lead screw matches the inner wall pattern of the threaded cylinder, and the lead screw, the threaded cylinder and the sealing plate are in the same vertical line.

[0010] Preferably, a support table is installed below the interior of the heating frame. Fixed bolts are assembled between the top plate and the screw holes on both sides of the water tank. Cylinders are respectively installed on both sides of the top plate, and a lifting plate is fixed to the bottom of the piston rod of the cylinder. Electric rollers are respectively assembled between the front and back of the upper part inside the support table and the lifting plate.

[0011] Preferably, the lifting plate is located below the top plate, and the lifting plate can vertically lift and lower synchronously with the piston rod of the cylinder.

[0012] Preferably, connection blocks are respectively arranged on both sides of the bottom of the top plate, and fastening bolts are assembled between the connection blocks and the screw holes of the top plate. Plug rods are welded to the sides of the connection blocks, and suspension rods are sleeved outside the plug rods. Holes are arranged inside the top ends of the suspension rods, and a sieve frame is horizontally welded between the bottoms of the suspension rods.

[0013] Preferably, the suspension rods are horizontally embedded in the holes, and the suspension rods are symmetrically fixed on both sides of the top of the sieve frame.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The surface heat treatment device for metal processing not only realizes the linkage in terms of heating and cooling, facilitates the feeding and discharging of materials, but also realizes the collection of metal chips.

[0015] (1) By welding a sealing plate at the bottom of the threaded cylinder, the through grooves I on both sides of the heating frame are blocked by the sealing plate. If a metal plate is sent to the heating frame and placed on the surface of the support table, then the motors installed on the two side brackets are started, and the bevel gear I meshes with and drives the bevel gear II to synchronously rotate the lead screw. Since the threaded cylinder is embedded in the sliding groove by means of the slider, the sealing plate can vertically sink and block the through grooves I on both sides when the lead screw rotates, avoiding the temperature drop of the surrounding environment when the flame spray gun heats the metal plate.

[0016] (2) By respectively assembling electric rollers between the front and back of the upper part inside the support table and the lifting plate, the electric rollers on the top of the support table and the lifting plate rotate at the same speed. If the metal plate is heated, then the electric rollers on the surface of the support table are started to move through the through groove I towards the through groove II. The two groups of cylinders are started in advance, and the piston rod raises the lifting plate to receive the metal material, and then the lifting plate sinks to immerse the metal plate in the cold water of the water tank for rapid cooling. The liquid in the water tank can also be discharged through the pipeline at the lower right corner for circulating cooling.

[0017] (3) By horizontally welding a sieve frame between the bottoms of the suspension rods, aligning the screw holes between the connection blocks and the top plate and screwing in the fastening bolts for reinforcement, and then sleeving the sieve frame outside the plug rods through the holes of the suspension rods on both sides, the sieve frame is located below the interior of the water tank and immersed below the liquid level. If the outer wall of the metal plate soaked above drops off, it will be exactly received. After the heat treatment is completed, the top plate is lifted and the sieve frame is disassembled to clean the garbage, maintaining the cleanliness of the bottom environment of the water tank.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a surface heat treatment device for metal processing, including a substrate 1 and a heating frame 2. A heating frame 2 is installed on the left side of the top of the substrate 1, and first through grooves 5 are respectively provided at the centers of both sides of the heating frame 2. Brackets 10 are respectively welded on both sides of the outer top of the heating frame 2, and a motor 11 is installed on the outside of the brackets 10. A first bevel gear 12 is fixed on the output end of the motor 11. Lead screws 9 are respectively movably connected to both sides above the inside of the heating frame 2, and a second bevel gear 13 is fixed at the top of the lead screws 9. A threaded cylinder 8 is sleeved on the outside of the lead screws 9. A sealing plate 4 is welded at the bottom of the threaded cylinder 8, and a slider 6 is welded above the side surface of the sealing plate 4. Sliding grooves 7 are respectively provided above the left and right sides inside the heating frame 2. Two groups of flame spray guns 21 are fixed on the top of the heating frame 2. A water tank 20 is installed on the right side of the top of the substrate 1, and second through grooves 16 are respectively provided inside both sides above the water tank 20. A top plate 15 is lapped on the top of the water tank 20;

[0025] The slider 6 is embedded inside the chute 7. The slider 6 can vertically rise and fall along the chute 7. The first bevel gear 12 is meshed and connected to the side of the top of the second bevel gear 13. The bottom of the second bevel gear 13 is movably connected to the surface of the heating frame 2. The thread pattern on the outer wall of the lead screw 9 matches the thread pattern on the inner wall of the threaded barrel 8. The lead screw 9, the threaded barrel 8, and the sealing plate 4 are in the same vertical line;

[0026] Specifically, as Figure 1 and Figure 2 shown, the first through grooves 5 on both sides of the heating frame 2 are blocked by the sealing plate 4. After the metal sheet is sent to the heating frame 2 and placed on the surface of the support platform 3, the motors 11 installed on the two side brackets 10 are started, and the first bevel gear 12 is used to meshingly drive the second bevel gear 13 to synchronously rotate the lead screw 9. Since the threaded barrel 8 is embedded in the chute 7 by the slider 6, when the lead screw 9 rotates, the sealing plate 4 can vertically descend and block the first through grooves 5 on both sides.

[0027] A support platform 3 is installed below the interior of the heating frame 2. Fixing bolts 22 are assembled between the screw holes on both sides of the top plate 15 and the water tank 20. Cylinders 14 are respectively installed on both sides of the top plate 15, and the bottom of the piston rod of the cylinder 14 is fixed with a lifting plate 19. Electric rollers 27 are respectively assembled between the front and back of the upper part inside the support platform 3 and the lifting plate 19. The lifting plate 19 is located below the top plate 15, and the lifting plate 19 can vertically rise and fall synchronously with the piston rod of the cylinder 14;

[0028] Specifically, as Figure 1 and Figure 3 shown, the electric rollers 27 on the top of the support platform 3 and the lifting plate 19 rotate at the same speed. If the metal sheet is heated, the electric rollers 27 on the surface of the support platform 3 are started to move through the first through grooves 5 towards the second through grooves 16. Two groups of cylinders 14 are started in advance, and the piston rods lift the lifting plate 19 to receive the metal material, and then the lifting plate 19 sinks to immerse the metal plate in the cold water of the water tank 20 for rapid cooling. The liquid in the water tank 20 can also be discharged through the pipeline in the lower right corner for circulating cooling.

[0029] Connection blocks 24 are respectively arranged on both sides of the bottom of the top plate 15. Fixing bolts 23 are assembled between the screw holes of the connection blocks 24 and the top plate 15. A plug rod 26 is welded to the side of the connection block 24, and a suspension rod 17 is sleeved outside the plug rod 26. A hole 25 is arranged inside the top end of the suspension rod 17. A sieve frame 18 is horizontally welded between the bottoms of the suspension rods 17. The suspension rods 17 are horizontally embedded in the holes 25, and the suspension rods 17 are symmetrically fixed on both sides of the top of the sieve frame 18;

[0030] Specifically, as Figure 1 、 Figure 3 and Figure 4As shown, align the screw holes between the alignment connection block 24 and the top plate 15 and screw in the fastening bolts 23 for reinforcement. Then, sleeve the sieve frame 18 outside the insertion rod 26 through the holes 25 on both sides of the suspension rods 17, so that the sieve frame 18 is located below the inside of the water tank 20 and immersed below the liquid level. If the outer wall of the metal plate soaked above falls off, it can be just received. After the heat treatment is completed, lift the top plate 15 and remove the sieve frame 18 to clean the garbage.

[0031] Working principle: When the utility model is in use, the through slots 5 on both sides of the heating frame 2 are blocked by the sealing plates 4. If the metal plate is sent to the heating frame 2 and placed on the surface of the support table 3, then start the motors 11 installed on the brackets 10 on both sides, and use the bevel gear 12 to engage and push the bevel gear 13 to synchronously rotate the lead screw 9. Since the threaded barrel 8 is embedded in the sliding groove 7 by the slider 6, when the lead screw 9 rotates, it can vertically sink the sealing plate 4 and block the through slots 5 on both sides. If the metal plate is heated, start the electric roller 27 on the surface of the support table 3 to move through the through slot 5 towards the through slot 16. Pre-start the two groups of cylinders 14, and use the piston rod to lift the lifting plate 19 to receive the metal material, and then sink the lifting plate 19 to immerse the metal plate in the cold water of the water tank 20 for rapid cooling. The liquid in the water tank 20 can also be discharged through the pipeline at the lower right corner for circulating cooling. Align the screw holes between the alignment connection block 24 and the top plate 15 and screw in the fastening bolts 23 for reinforcement. Then, sleeve the sieve frame 18 outside the insertion rod 26 through the holes 25 on both sides of the suspension rods 17, so that the sieve frame 18 is located below the inside of the water tank 20 and immersed below the liquid level. If the outer wall of the metal plate soaked above falls off, it can be just received.
