Description

Technical Field

[0001] The invention relates to the technical field of automobile die-casting molds, and more specifically to a tempering device for producing automobile die-casting molds. Background Art

[0002] Tempering is a metal heat treatment process, which is mainly used to improve the performance of materials and achieve a balance between strength, hardness and toughness. It is usually carried out after quenching, with the purpose of eliminating the internal stress formed during the quenching process, reducing brittleness, improving toughness and plasticity, while ensuring that the material still has a certain strength and hardness. In the production process of automotive die-casting molds, the equipment used for tempering treatment is usually called a tempering furnace.

[0003] After tempering is completed, the cooling process is a very critical step, which directly affects the organizational structure and performance of the mold. For high-alloy steel molds or workpieces that need to be cooled quickly to obtain specific properties, liquid cooling is usually used to ensure cooling speed and workpiece quality. After long-term use of the water cooling system of the tempering furnace, a large amount of scale may accumulate in the cooling pipe, which will reduce the cooling efficiency and even cause pipe blockage and equipment failure.

[0004] The traditional way to clean scale is usually to inject an acidic or special descaling agent solution into the cooling pipe, dissolve the scale by circulation or immersion, and then rinse the pipe thoroughly with clean water. Although this method can significantly remove most of the scale, the cleaning process requires a long cycle time and is time-consuming. At the same time, although most of the scale will loosen under the action of the descaling liquid and be washed away with clean water, it is still difficult to completely remove stubborn scale, especially the deposits firmly attached to the surface of the pipe, which may affect the long-term operation efficiency of the system. Therefore, it is necessary to propose a tempering device for automobile die-casting mold production to solve the above problems. Summary of the invention

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. During the process of inserting several deep rods into each cooling tube, the gear and the rack cooperate to drive the rotating drum inside each deep rod to rotate forward. During the forward rotation of the rotating drum, not only the scraper is driven to rotate through the chassis to loosen and break the stubborn scale attached to the inner wall of the cooling tube, so that the scale falls off quickly; but also the pressure blocks arranged in a circular array on the outer wall of the rotating drum will resist the wedge blocks, and then cooperate with the first spring to make the scraper bounce up and down, and the scraper will resist the inner wall of the cooling tube.

[0020] 2. In the process of taking out the penetration rod, the drum reverses, and the push block is pushed to move by a number of extrusion teeth on the outside of the ratchet ring, thereby prompting the piston to compress the anti-stick coating inside the piston chamber, so that the anti-stick coating is evenly sprayed from the nozzle on the inner wall of the cooling pipe, reducing the scale formation and adhesion on the inner wall of the cooling pipe and reducing the difficulty of pipeline maintenance; the ratchet ring rotates while driving the disc to rotate, thereby the top block contacts the swing block, causing the nozzle to swing up and down during the spraying of the anti-stick coating, thereby expanding the spraying range and improving the efficiency of spraying the anti-stick coating.

[0021] 3. The reversal of the rotating drum will also cause the slide bar sliding in the inner ring groove to switch to slide in the outer ring groove. During the switching process, the coating brush is driven to slide out of the storage groove and hit the inner wall of the cooling tube. As the chassis is reversed, the coating brush is driven to brush the inner wall of the cooling tube, and the sprayed anti-stick coating is evenly spread, so that the anti-stick coating is evenly coated on the inner wall of the cooling tube, thereby improving the adhesion effect of the anti-stick coating. During the coating process of the coating brush, the anti-stick coating in the liquid supply cavity can also be guided into the sliding box through the second hose for the coating brush to absorb, thereby supplementing the anti-stick coating sprayed by the spraying mechanism during the coating process, so that the anti-stick coating is coated more evenly and fully.

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] For example, see Figures 1 to 15 As shown, the present invention discloses a tempering device for automobile die-casting mold production, comprising a tempering mechanism 1 including a tempering furnace 11, four racks 12 are symmetrically arranged on the top surface of the tempering furnace 11, two water grooves 13 are symmetrically arranged at the upper and lower ends of both sides of the tempering furnace 11, and a plurality of cooling pipes 14 are equidistantly connected between the two water grooves 13 on each side of the tempering furnace 11;

[0041] A penetration mechanism 2 is installed inside the cooling tube 14, and the penetration mechanism 2 includes a plurality of penetration rods 22 slidably connected to each cooling tube 14, and the tops of the plurality of penetration rods 22 are installed on the bottom surface of the cross beam 21, and the cross beam 21 is on the top surface of the tempering furnace 11, and an inner rod 23 is rotatably connected inside the cross beam 21, and a plurality of worm gears 24 are equidistantly arranged on the inner rod 23, and gears 25 are installed at both ends of the inner rod 23, and the gears 25 are meshed and connected with the corresponding racks 12.

[0042] A rotating mechanism 3 is installed inside the penetration rod 22. The rotating mechanism 3 includes a rotating drum 31 rotatably connected to the penetration rod 22. A worm gear 32 is installed on the top of the rotating drum 31. The worm gear 32 is meshed and connected with the corresponding worm 24.

[0043] A descaling mechanism 6 is installed at the bottom end of the penetration rod 22. The descaling mechanism 6 includes a bottom plate 68 installed at the bottom end of the drum 31. The bottom plate 68 has a cylindrical circumferential array with a plurality of scrapers 691.

[0044] The rotating mechanism 3 also includes a plurality of through holes 33 in a circumferential array at the lower end of the rotating drum 31, a plurality of pawls 34 are arranged in a circumferential array on the outer side of the lower end of the rotating drum 31, a ratchet ring 35 is rotatably mounted on the outer side of the lower end of the rotating drum 31, the plurality of pawls 34 are engaged with the ratchet ring 35, a plurality of extrusion teeth 36 are arranged in a circumferential array on the outer side of the ratchet ring 35, a disc 37 is fixed to the bottom end of the ratchet ring 35, a plurality of top blocks 38 are arranged in a circumferential array on the top edge of the disc 37.

[0045] A scraping mechanism 4 is provided at the lower end of the deepening rod 22, and the scraping mechanism 4 includes a spring box 41 provided at the bottom end of the deepening rod 22, a first spring 42 is installed in the spring box 41, a scraper 43 is installed on the outer side of the lower end of the deepening rod 22, a plurality of wedge blocks 44 are arranged in an inner circumferential array of the scraper 43, and the bottom surface of the wedge block 44 abuts against the top end of the first spring 42, a plurality of pressure blocks 45 are arranged in an outer circumferential array of the rotating drum 31, and the pressure blocks 45 abut against the top surface of the wedge blocks 44.

[0046] After the tempering of the automobile die-casting mold is completed, the traditional tempering furnace 11 introduces cooling water from the water trough 13 at the bottom of the tempering furnace 11. The cooling water enters each cooling tube 14 from bottom to top, and is discharged from the water trough 13 at the upper end of the tempering furnace 11 after filling the cooling tube 14, forming a cycle. The cooling water entering several cooling tubes 14 absorbs the temperature inside the tempering furnace 11, thereby reducing the temperature of the automobile die-casting mold. After the cooling water circulates in the cooling tube 14 for a long time, a large amount of scale will be generated and attached to the inner wall of the cooling tube 14. In mild cases, the cooling water flow rate will be reduced and the cooling water flow rate will be slowed down; in severe cases, the wall thickness may be increased, the thermal conductivity efficiency will be reduced, and thus the cooling effect will be reduced. Therefore, after the cooling tube 14 has been running for a certain period of time, a cleaning solvent will be introduced to dissolve the scale, and then it will be flushed with water circulation. However, after cleaning in this way, the inner wall of the cooling tube 14 is likely to still be attached with stubborn scale that is difficult to remove. In the subsequent use process, the scale will not only reduce the cooling effect, but also adhere to the inner wall of the cooling tube 14, causing the tube wall surface to become less flat and smooth, thereby forming rough spots and attachment points. This situation will accelerate the accumulation of scale, gradually deteriorate the cooling performance of the pipeline and increase the difficulty of cleaning.

[0047] Therefore, after the above-mentioned cleaning agent is used to flush the cooling pipes 14, the plurality of penetration rods 22 installed at the bottom of the cross beam 21 are respectively inserted into the corresponding cooling pipes 14 at the top of the tempering furnace 11, and at the same time, the gears 25 at both ends of the cross beam 21 are respectively meshed and connected with the corresponding racks 12 on the top surface of the tempering furnace 11. When the crossbeam 21 is pushed downward to make the several penetration rods 22 slide to the bottom of the cooling pipe 14, the gear 25 cooperates with the corresponding rack 12 to drive the inner rod 23 inside the crossbeam 21 to rotate, and the inner rod 23 drives the several worm gears 24 evenly distributed thereon to rotate, and the worm gear 24 then cooperates with the worm wheel 32 at the upper end of the corresponding rotating cylinder 31 to drive the corresponding rotating cylinder 31 to rotate forward in its respective penetration rod 22. A chassis 68 is installed at the bottom end of the rotating cylinder 31. When the rotating cylinder 31 rotates in the penetration rod 22, the rotating cylinder 31 simultaneously drives the chassis 68 to rotate forward at the bottom end of the penetration rod 22. A plurality of scrapers 691 are evenly arranged on the cylindrical surface of the chassis 68. During the rotation process, the scraper 691 loosens and breaks the stubborn scale attached to the inner wall of the cooling pipe 14, so that the scale can be easily fallen off (the scraper 691 does not conflict with the inner wall of the cooling pipe 14, thereby avoiding scratching the inner wall of the cooling pipe 14).

[0048] A scraper 43 is slidably connected to the penetration rod 22 above the chassis 68, and a plurality of pressure blocks 45 in a circular array on the surface of the rotating drum 31 inside the spring box 41 rotate synchronously with the rotating drum 31. During the rotation of the pressure blocks 45, they cyclically resist a plurality of wedge blocks 44 installed on the inner wall of the scraper 43, thereby applying a downward force to the scraper 43, causing the scraper 43 to slide downward, and the scraper 43 compresses the first spring 42; when the pressure blocks 45 no longer squeeze the wedge blocks 44, the first spring 42 pushes the scraper 43 upward again. During the up and down reciprocating bouncing of the scraper 43 and the continuous descent of the penetration rod 22, the scraper 43 can easily scrape off the loosened or broken scale of the scraper 691. At the same time, the scraper 43 can prevent the scale from splashing when the scraper 691 is breaking the scale, so that all the scale falls into the water trough 13 below the tempering furnace 11. The above process can effectively remove the stubborn scale on the inner wall of the cooling tube 14, thereby removing the scale as much as possible, reducing scale accumulation, improving cooling efficiency and reducing the difficulty of subsequent cleaning.

[0049] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 15A spray mechanism 5 is installed at the bottom end of the penetration rod 22, and the spray mechanism 5 includes a spray box 51 installed at the bottom end of the penetration rod 22. The rotating drum 31 passes through the spray box 51, and the ratchet ring 35 and the disc 37 are rotatably connected to the inside of the spray box 51. The spray box 51 has a plurality of liquid guide cavities 52 in a circumferential array, and each liquid guide cavity 52 is connected to a corresponding through hole 33. The spray box 51 has a plurality of piston chambers 53 in a circumferential array, and each piston chamber 53 is connected to the corresponding liquid guide cavity 52. ​​A second spring 54 and a piston 55 are installed in each piston chamber 53. The piston 55 is connected to the corresponding liquid guide cavity 52 by the second spring. 54 is elastically connected to the piston chamber 53, a push block 56 is fixed to the side of the piston 55, and the extrusion tooth 36 abuts against the push block 56, a plurality of nozzles 57 are arranged in a circular array in the spray box 51, a pendulum block 58 is installed at the tail end of each nozzle 57, and the top block 38 abuts against the pendulum block 58, a first rotating shaft 59 is installed on both sides of the nozzle 57, a first torsion spring 591 is installed on the first rotating shaft 59, the first rotating shaft 59 is rotatably connected to the inside of the spray box 51 through the first torsion spring 591, a first hose 592 is installed at the tail end of the nozzle 57, and the first hose 592 is communicated with the corresponding piston chamber 53.

[0050] When the rotating drum 31 is rotating forwardly into the rod 22, it will also drive several pawls 34 to rotate. In this direction of rotation, the pawls 34 will not engage with the ratchet ring 35, and thus cannot drive the ratchet ring 35 to rotate together. That is, the ratchet ring 35 is stationary at this time, and the rotating drum 31 rotates relative to the ratchet ring 35.

[0051] After the penetration rod 22 drives the entire descaling mechanism 6 to move to the bottom end of the cooling pipe 14, the crossbeam 21 is pulled upward, and the plurality of penetration rods 22 slide toward the top of the cooling pipe 14. During this process, the gear 25 cooperates with the rack 12 to drive the inner rod 23 to reverse, and the inner rod 23 cooperates with the corresponding worm gear 32 through the plurality of worms 24 to drive the rotating drum 31 to reverse, and the rotating drum 31 drives the chassis 68 to reverse, and at the same time, the rotating drum 31 still drives the scraper 43 to move up and down through the pressing block 45. During the rising process of the penetration rod 22, the scraper 43 plays the role of scraping off the scale residues remaining on the inner wall of the cooling pipe 14.

[0052] A one-way valve 593 is installed at the connection between the liquid-conducting cavity 52 and the piston chamber 53 and inside the first hose 592. During the ascending process of the penetration rod 22, an anti-stick coating (such as polytetrafluoroethylene) is introduced into the rotating drum 31, and a part of the anti-stick coating inside the rotating drum 31 flows into the liquid-conducting cavity 52 in the spray box 51 through the through hole 33. When the rotating drum 31 is reversed, the ratchet 34 is driven to reverse, and the ratchet 34 and the ratchet ring 35 are engaged with each other in this direction (in the prior art, a torsion spring for resetting and applying torsion is installed inside the ratchet 34, and a plurality of support seats are arranged in a circumferential array on the surface of the rotating drum 31, and a round rod is installed on the support seat, and the ratchet 34 is rotatably connected to the rotating drum 31 through the round rod, and the support seat can make the ratchet 34 rotate only in one direction, and the other direction will cause a conflict and prevent the ratchet 34 from rotating), thereby driving the ratchet ring 35 to reverse with the rotating drum 31. During the reversal process, the plurality of extrusion teeth 36 on the outer wall of the ratchet ring 35 intermittently contact and squeeze the push plug block 56, so that the piston 55 compresses the anti-stick coating inside the piston chamber 53 and compresses the second spring 54 at the same time (when the extrusion teeth 36 do not contact the push plug block 56, the second spring 54 is in a natural state, the piston 55 is at the end of the piston chamber 53, and the one-way valve 593 at the connection between the piston chamber 53 and the liquid guide cavity 52 is opened, and the anti-stick coating in the liquid guide cavity 52 enters the piston chamber 53). The pressure of the piston 55 causes the one-way valve 593 at the connection between the liquid guide cavity 52 and the piston chamber 53 to open. The valve 593 is closed, and the one-way valve 593 in the first hose 592 is opened. The piston 55 pushes the anti-stick coating inside the piston chamber 53 into the first hose 592 and then into the nozzle 57. The pressure generated by the piston 55 causes the anti-stick coating to be sprayed out from the nozzle 57 and evenly sprayed on the inner wall of the cooling pipe 14. The anti-stick coating has excellent anti-stick properties. Spraying it on the inner wall of the cooling pipe 14 can effectively prevent the deposition of calcium and magnesium ions on the pipe wall, reduce scale generation and adhesion, reduce the difficulty of pipeline maintenance, and increase the service life of the cooling pipe 14.

[0053] In order to improve the spraying effect of the nozzle 57, a disc 37 is provided at the bottom end of the ratchet ring 35. The disc 37 rotates with the ratchet ring 35, so that the top block 38 on the top surface of the disc 37 contacts the swing block 58 at the tail end of each nozzle 57, so that the nozzle 57 swings around the first rotating shaft 59 and compresses the first torsion spring 591. The nozzle 57 swings up and down to spray the anti-stick coating, thereby expanding the spraying range and improving the efficiency of spraying the anti-stick coating.

[0055] The descaling mechanism 6 further includes a liquid supply chamber 69 disposed inside the bottom plate 68 , and the bottom end of the drum 31 is in communication with the liquid supply chamber 69 .

[0056] A coating mechanism 7 is installed inside the chassis 68, and the coating mechanism 7 includes a plurality of receiving grooves 71 arranged in a circular array on the cylindrical surface of the chassis 68, and a sliding box 72 and a third spring 73 are installed in each receiving groove 71, and the sliding box 72 is elastically connected to the receiving groove 71 through the third spring 73, and a sliding rod 74 is fixed to the top of the sliding box 72, and the sliding rod 74 passes through the top surface of the chassis 68 and is slidably connected to the inner ring groove 62, and a second hose 75 is connected to the back of the sliding box 72, and the second hose 75 is connected to the liquid supply cavity 69, a push block 76 is installed on the bottom surface of the sliding box 72, and a coating brush 77 is installed on the front surface of the sliding box 72.

[0057] A dustproof mechanism 8 is installed in the chassis 68, and the dustproof mechanism 8 includes two sealing doors 81 slidably connected to each storage groove 71, and a slider 82 is installed on the bottom surface of each sealing door 81, and the corresponding push block 76 abuts against every two sliders 82, and a fourth spring 83 is installed on the side of each slider 82, and the slider 82 is elastically connected to the inside of the chassis 68 through the fourth spring 83.

[0058] When the rotating drum 31 drives the chassis 68 to rotate forward, the sliding rod 74 at the top of each sliding box 72 slides in the inner circumference of the inner ring groove 62 on the bottom surface of the top plate 61, causing each sliding box 72 to be at the innermost end of the corresponding receiving groove 71 and compressing the third spring 73. In addition, when the sliding rod 74 rotates to the end of the inclined groove 64 connected to the inner ring groove 62, the sliding rod 74 is blocked by the guide plate 66, thereby guiding the sliding rod 74 to continue to slide in the inner ring groove 62 instead of sliding into the inclined groove 64. Because of the movement in this direction, when the sliding rod 74 hits the guide plate 66, it will cause the guide plate 66 to rotate around the second rotating shaft 65, and the guide plate 66 will compress the corresponding second torsion spring 67. After the rotation, the guide plate 66 closes the corresponding inclined groove 64, causing the sliding rod 74 to only continue to slide in the inner ring groove 62. When the rotating drum 31 drives the chassis 68 to reverse, several slide bars 74 reverse in the inner ring groove 62. When the slide bars 74 again hit the guide plate 66 at the connection between the inner ring groove 62 and the inclined groove 64, although the guide plate 66 has a tendency to rotate, it is blocked by the top plate 61 entity in the rotation direction and cannot continue to rotate, that is, the guide plate 66 guides the slide bars 74 into the corresponding inclined groove 64.

[0059] Each storage slot 71 is provided with a double-opening sealing door 81 at the outer end thereof, which serves to seal the storage slot 71 during the cleaning process to prevent the removed scale residue from entering the storage slot 71, thereby protecting the coating brush 77 from being contaminated. When the slide bar 74 slides in the corresponding inclined slot 64, the slide bar 74 drives the slide box 72 to slide outside the storage slot 71, releases the corresponding third spring 73, and drives the push block 76 at its bottom to slide, the push block 76 contacts and squeezes the slide block 82 at the bottom of the storage slot 71, causing the slide block 82 to slide to both sides of the storage slot 71, the slide block 82 compresses the fourth spring 83, and drives the sealing door 81 to slide to both sides of the storage slot 71, thereby opening the storage slot 71. At the same time, the sliding box 72 drives the coating brush 77 to slide outside the storage groove 71, and finally the coating brush 77 hits the inner wall of the cooling tube 14. As the chassis 68 reverses, the coating brush 77 spreads the anti-stick coating sprayed by the nozzle 57 on the inner wall of the cooling tube 14, evenly applies it, improves the adhesion effect of the anti-stick coating, and further improves the spraying effect of the anti-stick coating of the present invention. After the coating brush 77 hits the inner wall of the cooling tube 14, the slide bar 74 reaches the outer ring groove 63, and as the rotating drum 31 drives the chassis 68 to reverse, the slide bar 74 continues to rotate in the outer ring groove 63, and the principle of the slide bar 74 continuing to rotate in the outer ring groove 63 is the same as the principle of the slide bar 74 rotating in the inner ring groove 62 during forward rotation. A liquid supply chamber 69 is provided inside the chassis 68, and another part of the anti-stick coating that enters the inside of the rotating drum 31 enters the liquid supply chamber 69 from the bottom of the rotating drum 31. Each sliding box 72 is connected to the liquid supply chamber 69 through a second hose 75. Therefore, the anti-stick coating in the liquid supply chamber 69 enters the inside of the sliding box 72 through the second hose 75, and is then absorbed by the coating brush 77 and finally supplemented on the inner wall of the cooling tube 14, thereby supplementing the anti-stick coating sprayed by the spraying mechanism 5, so that the anti-stick coating is applied more evenly and fully.
