Description

Technical Field

[0001] The present invention relates to the field of quenching devices, in particular to a quenching device for machining and heat treatment of mechanical parts. Background Art

[0002] Quenching is a heat treatment process primarily used to increase the hardness, strength, and wear resistance of metal materials. This process involves heating the metal to a certain temperature and then rapidly cooling it to alter its structure and properties. Quenching can be applied to a variety of metals, including steel and cast iron. This process imparts high hardness and good wear resistance to the surface or the entire metal, while also improving its fatigue strength and impact resistance.

[0003] Existing quenching equipment is usually just a water pool or oil pool, and a robotic arm is used to place the steel heated to a certain temperature into the water pool or oil pool for quenching. During this process, the quenching liquid usually splashes and there is no protection, which easily increases the operational risk. At the same time, during long-term quenching, the quenching liquid in the quenching pool is usually accompanied by a large amount of steel slag, which cannot be cleaned in time, which also causes the quenching liquid to be seriously turbid, further affecting the quality of quenching.

[0004] The Chinese patent application number CN202211033127.4 discloses "a high-frequency quenching device for metal parts, belonging to the field of metal processing, which includes a support frame, a heating coil and a cooling box filled with coolant, the cooling box and the heating coil are fixedly connected to the support frame, the top of the support frame is provided on a cylinder for storing parts, a first block for preventing parts from falling is slidably provided on the cylinder, a support table for supporting parts is slidably provided on the support frame, the support table is slidably matched with the inner side wall of the support frame, a push rod for pushing parts is slidably provided on the side wall of the support frame away from the support table, the push rod is slidably matched with the support table, a control component for controlling the movement of the first block is provided on the support frame, and a first drive component for driving the push rod to move is provided on the support frame. This has the effect of improving the safety of high-frequency quenching."

[0005] However, the above technical solutions still cannot effectively prevent the splashing of quenching liquid caused by quenching large steel parts, nor can they filter and clean the quenching liquid in time.

[0021] Compared with the related art, the quenching device for heat treatment of mechanical parts provided by the present invention has the following beneficial effects:

[0022] 1. The present invention provides a quenching device for heat treatment of mechanical parts processing, which drives the lifting slider to move downward through an electric lifting slide rail, thereby driving the parts to be quenched in the loading frame to gradually descend into the quenching pool for quenching until the bottom of the mounting seat contacts the lower inner wall of the quenching pool. During the descending process, the lever can contact the slide plate after descending a distance, driving it to move downward and compress the spring, and then through the pull rope, pull the connecting block at the other end to move upward, thereby driving the folding baffle to expand upward, thereby shielding the front and rear sides during quenching to avoid splashing of quenching liquid and improve operation safety.

[0023] 2. The present invention provides a quenching device for heat treatment of mechanical parts processing, which drives the lifting slider to move upward by an electric lifting slide rail to move the quenched parts upward and out. At this time, the folding baffle is refolded under the action of the spring. At the same time, when the quenching liquid in the quenching pool needs to be cleaned, the lifting slider can be continued to be controlled to move upward after the quenched parts are removed, thereby driving the dial rod to move up a distance and then contact with the folding plate, thereby driving the folding plate to move up, and then the vertical rod, the slider and the L-shaped connecting rod are all moved upward until the mounting seat is completely moved up to the top of the quenching pool. During the process, the rotating plate is gradually separated from the inner wall of the quenching pool and the limit is cancelled. It will be rotated to a horizontal state limited by the limit plate under the action of the spring hinge. At the same time, as it continues to move upward, it will contact with the lower end of the contact plate, thereby driving the mounting seat to rotate as a whole, so that the filter screen limited by the limit bar will rotate from a horizontal state to a nearly vertical state, thereby realizing the dumping of steel slag on the filter screen to both sides of the quenching pool, thereby realizing the cleaning of steel slag in the quenching liquid.

[0024] 3. The present invention provides a quenching device for heat treatment of mechanical parts processing. Through the cooperation and interference between the electric control button and the boss, when the folding plate moves up until the two contact each other, the lifting slider stops moving upward. At this time, the vertical electric slide rail and the servo motor are running, and the cleaning roller brush is driven to move up and down while rotating, thereby realizing the cleaning of some difficult-to-dump steel slag on the filter screen that is rotated to a nearly vertical state. At the same time, the design of the protective cover can also avoid the splashing of steel slag during cleaning, greatly improving the cleaning effect.

[0025] The device can effectively protect the splashing of quenching liquid during the quenching process, and at the same time is convenient for filtering and cleaning the quenching liquid, and the cleaning effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described 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, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-8 The present invention provides a technical solution: a quenching device for heat treatment of mechanical parts processing, comprising a quenching pool 1, a fixed seat 2, an electric lifting slide 3, a lifting slider 4, a connecting rod 5, and a loading frame 6. The fixed seat 2 is fixedly connected to the center of the left and right sides of the quenching pool 1, and the upper end of each fixed seat 2 is fixedly connected to the electric lifting slide 3. The lifting slider 4 slides in the electric lifting slide 3, and the lifting sliders 4 on both sides are fixedly connected to the connecting rod 5 on the side close to each other. The loading frame 6 is fixedly connected between the sides of the connecting rods 5 on the left and right sides that are close to each other, and the loading frame 6 is directly above the quenching pool 1.

[0037] In this way, the electric lifting slide rail 3 can drive the lifting slider 4 to move downward, thereby driving the parts to be quenched in the loading frame 6 to gradually descend into the quenching tank 1 for quenching.

[0038] A base 7 is provided on the front and rear sides of the quenching pool 1, and a folding baffle 8 is fixedly connected to the base 7, and connecting blocks 17 are fixedly connected to the left and right sides of the upper end of the folding baffle 8. The folding baffle 8 is an existing structure in which the plates are continuously connected by hinges, specifically in a continuous M shape, and is made of high-temperature resistant material.

[0039] The left and right ends of the base 7 are also fixedly connected to a vertical slide frame 10, and a slide plate 11 is slidably connected in each vertical slide frame 10, and the front and rear ends of the slide plate 11 extend respectively on the front and rear sides of the vertical slide frame 10, and the front and rear sides of each connecting rod 5 are fixedly connected to a shift rod 9. The upper end surfaces of the front and rear slides 11 are close to each other and respectively cooperate with the lower end surfaces of the shift rod 9 on their respective sides. A convex plate 19 is fixedly connected to the slide plate 11, and is slidably connected to the vertical slide frame 10 through the convex plate 19. In this way, the sliding of the convex plate 19 in the vertical slide frame 10 can effectively stabilize the up and down sliding of the slide plate 11.

[0040] The slides 11 on the front and rear sides are each away from each other and are provided with an unfolding mechanism between the connecting block 17 on each side. The unfolding mechanism includes a collar 12, a guide slide 13, a spring 14, a mounting frame 15, a roller 16, and a pull rope 18. The vertical slide frames 10 on the front and rear sides are each away from each other and are provided with a guide slide 13 on the side, and the lower end of the guide slide 13 is fixedly connected to the upper end surface of the base 7. The slides 11 on the front and rear sides are also fixedly connected to the collar 12 on the end away from each other, and the collar 12 is slidably sleeved on each side. The outer side of the guide slide 13, a spring 14 is fixedly connected between the ring 12 and the upper end surface of the base 7, and the guide slides 13 on the front and rear sides are provided with a mounting bracket 15 on the side away from each other, and the lower end of the mounting bracket 15 is fixedly connected to the upper end surface of the base 7, and the upper end of the mounting bracket 15 is rotatably mounted with a roller 16, and a pull rope 18 is fixedly connected between the ring 12 and the connecting block 17 on each side. The pull rope 18 rolls and is wound around the top of the roller 16 on each side, and the spring 14 is sleeved on the outer side of the guide slide 13.

[0041] When the lifting slider 4 moves downward, the lever 9 can contact the slide plate 11 after it has dropped a certain distance, thereby driving it to move downward and compressing the spring 14, and then pulling the pull rope 18 downward through the ring 12, and the other end of the pull rope 18 will pull the connecting block 17 upward, thereby driving the folding baffle 8 to unfold upward, thereby shielding the front and rear sides during quenching to avoid splashing of quenching liquid and improve the safety of operation.

[0042] After quenching is completed, the electric lifting rail 3 can be used to drive the lifting slider 4 to move up, so that the quenched parts can be moved up and out. At this time, under the action of the spring 14, the folding baffle 8 is refolded.

[0043] A vertical slide frame 20 is fixedly installed on the front and rear ends of the left and right side surfaces of each quenching pool 1, and a slider 21 is slidably connected to the vertical slide frame 20. The upper end of each slider 21 is fixedly connected to a vertical rod 22, and the upper end of the vertical rod 22 extends to the outer side of the upper end of the vertical slide frame 20, and is fixedly connected to a folding plate 23 at the extended end. The lower end surface of the folding plate 23 cooperates and abuts against the upper end surface of the shift rod 9 on each side. The side of the vertical rod 22 close to the quenching pool 1 is also fixedly connected to an L-shaped connecting rod 24, which extends into the quenching pool 1 and is rotatably connected to a mounting seat 25 through a spring hinge. A filter screen 26 is fixedly connected between the left and right mounting seats 25 on the same front and rear side. A flip mechanism is also installed on the mounting seat 25, and a cleaning mechanism is also installed on the vertical slide frame 20.

[0044] The flip mechanism includes a limit plate 27, a rotating plate 28, a limit bar 29, a guide block 30, a fixed vertical plate 31, and a stop plate 32. The limit plate 27 is fixedly connected between the left and right mounting seats 25 on the same side of the front and rear. The limit plates 27 on the front and rear sides are on the side where the front and rear filters 26 are away from each other. The left and right mounting seats 25 on the same side of the front and rear are also rotatably connected with a rotating plate 28 through a spring hinge, and the rotating plate 28 is above the limit plate 27 on each side. The left and right ends of the rotating plates 28 on the front and rear sides are fixed on the side away from each other. A guide block 30 is fixedly connected, and the guide block 30 is in contact with the upper end of the limit plate 28 on each side, and the guide block 30 also slides and fits with the inner wall of the quenching pool 1. The left and right ends of the front and rear sides of the quenching pool 1 are fixedly connected with fixed vertical plates 31. The fixed vertical plates 31 on the left and right sides are fixedly connected with a push plate 32 on one side close to each other, and the lower end of the push plate 32 cooperates and contacts with the rotating plate 28. The L-shaped connecting rods 24 on the left and right sides are fixedly connected with a limit strip 29 on one side close to each other. The limit strip 29 is below the filter screen 26 and is limited by the filter screen 26.

[0045] When the quenching liquid in the quenching tank 1 needs to be cleaned, after quenching is completed, the parts can be removed and the lifting slide 4 can be continued to be controlled to move upward, thereby driving the dial rod 9 to move up a distance and then contact the folding plate 23, thereby driving the folding plate 23 to move up, and then the vertical rod 22, the slide 21 and the L-shaped connecting rod 24 are all moved up until the mounting seat 25 is completely moved up to the top of the quenching tank 1. In the process, since the rotating plate 28 gradually separates from the inner wall of the quenching tank 1 and the limit is cancelled, it will rotate to the horizontal state limited by the limit plate 27 under the action of the spring hinge. At the same time, as it continues to move upward, it will contact the lower end of the abutting plate 32, thereby driving the mounting seat 25 as a whole to overcome the elastic force of the spring hinge between it and the L-shaped connecting rod 24 and rotate, so that the filter screen 26 limited by the limit bar 29 will rotate from the horizontal state to a nearly vertical state, thereby realizing the pouring of the steel slag on the filter screen 26 to the two sides of the quenching tank 1, thereby realizing the cleaning of the steel slag in the quenching liquid.

[0046] The fixed vertical plates 31 on the left and right sides are located on the outside of the left and right ends of the rotating plate 28, and the lower ends of the abutment plates 32 on the left and right sides are higher than the lower ends of the fixed vertical plates 31 and are located above the rotating plate 28. In this way, the abutment plates 32 can be set at a position where they can overlap with the rotating plate 28 on the left and right sides, and the connection between the two can be easily achieved, so that the abutment plates 32 can contact with the rotating plate 28 and drive the mounting base 25 to rotate as a whole.

[0047] The guide block 30 and the limiting plate 27 are provided with corresponding limiting inclined surfaces 301, and the limiting inclined surfaces 301 cooperate to limit. The guide block 30 is slidably connected to the inner wall of the quenching pool 1 through the limiting inclined surfaces 301. In this way, through the inclined surface design on the guide block 30, when the filter screen 26 moves down and resets, the rotating plate 28 can be well contacted with the inner wall of the quenching pool 1 through the guide block 30, thereby overcoming the force of the spring hinge and rotating from the horizontal to the vertical state again.

[0048] The cleaning mechanism includes a vertical electric slide rail 33, a vertical slider 34, a servo motor 35, and a cleaning roller brush 36. The vertical slide frames 20 on the front and rear sides are fixedly installed with vertical electric slide rails 33 on the sides away from each other. A vertical slider 34 is slidably connected in each vertical electric slide rail 33. The vertical electric sliders 34 on the left and right sides are extended to the outside of the vertical electric slide rail 33 on the side close to each other, and a servo motor 35 is fixedly installed at the extended end. A cleaning roller brush 36 is fixedly installed between the left and right servo motors 35 on the same side of the front and rear, and the cleaning roller brush 36 is rollingly connected to the surface of the filter screen 26 on each side.

[0049] Bosses 40 are fixedly installed on the front and rear sides of the electric lifting slide 3, and an electric control button 39 is fixedly installed on the upper end of each folding plate 23. The electric button 39 cooperates and interferes with the lower end surface of the boss 40. The electric control button 39 is electrically connected to the vertical electric slide 33. The upper end of the vertical slider 34 is fixedly connected with an L-shaped connecting rod 37, and the L-shaped connecting rod 37 extends to the outside of the vertical electric slide 33. A protective cover 38 is fixedly connected between the left and right L-shaped connecting rods 37 on the same front and rear side.

[0050] Through the cooperation and interference of the electric control button 39 and the boss 40, when the folding plate 23 moves to the point where the two contact each other, the lifting slider 4 stops moving upward. At this time, the vertical electric slide rail 33 and the servo motor 35 are running, and the cleaning roller brush 36 is driven to move up and down while rotating, thereby cleaning some difficult-to-dump steel slag on the filter screen 26 that has rotated to a nearly vertical state. At the same time, the design of the protective cover 38 can also avoid the splashing of steel slag during cleaning, greatly improving the cleaning effect.
