Description

Technical Field

[0001] This utility model mainly relates to the field of tunnel furnace technology, specifically to a discharge mechanism of a continuous quenching device. Background Technology

[0002] Using a tunnel furnace for continuous quenching of workpieces allows for the processing of a large number of workpieces in a short time. The hardness and strength of the material can be controlled through preheating, high-temperature heating, rapid cooling, and tempering, effectively removing internal stress from the workpiece.

[0003] To meet the demand for discharging a large number of workpieces, a cooling oil tank and a chain conveyor are usually installed on the discharge side of the tunnel furnace. The workpieces are cooled in the cooling oil tank and discharged in batches by the chain conveyor in the oil tank.

[0004] The inventor proposes a discharge mechanism for a continuous quenching device. By setting up an oil tank, a chain conveyor line, and a roller conveyor line with adjustable working height, the workpieces undergoing quenching can be conveniently dropped from the oil tank onto the workpiece box placed on the roller conveyor line, reducing the drop height of the workpieces and effectively avoiding damage and scratches caused by excessive drop height.

[0006] This invention provides a discharge mechanism for a continuous quenching device, which solves the technical problem of unreasonable discharge route design in existing equipment.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a discharge mechanism for a continuous quenching device, comprising the following structure:

[0009] An oil tank is provided with a chain conveyor line fixed inside the oil tank, and the front discharge side of the chain conveyor line extends to the outside of the front end of the oil tank.

[0010] The base has a positioning plate on top, and a roller conveyor line is detachably attached to the top of the positioning plate. The discharge side of the chain conveyor line is directly above the roller conveyor line.

[0011] Furthermore, a receiving frame that cooperates with the discharge side of the tunnel furnace is fixedly provided on the rear side of the oil tank. The discharge port of the receiving frame extends to the top rear side of the chain conveyor line. The width of the discharge port of the receiving frame is smaller than the width of the chain conveyor line. A cover is detachably snapped onto the top of the oil tank.

[0012] Furthermore, an electric actuator is fixedly provided on the left side of the base, and a first connecting rod is movably connected to both the front and rear ends of the left side of the base. The top output end of the electric actuator is movably connected to the middle part of the first connecting rod, and a second connecting rod is movably connected to the middle part of the first connecting rod. The top of the second connecting rod is movably connected to the bottom left side of the positioning plate.

[0013] The base has a sliding rail fixed on both the front and rear sides of the right end. The top of the sliding rail is slidably connected to a sliding seat, and the top of the sliding seat is movably connected to the bottom of the second connecting rod.

[0014] Furthermore, a positioning seat is fixedly provided at the left end of the base, and a limit spring is detachably snapped onto the top of the positioning seat. A traction steel wire is fixedly provided on the top of the limit spring.

[0015] Furthermore, the positioning plate has upper slide rails fixed on both the front and rear sides of the right end, and upper slide blocks are slidably connected to the bottom of the upper slide rails. The bottom of the upper slide blocks is movably connected to the top of the first connecting rod. The positioning plate has a guide seat fixed on the bottom of the left end, and a guide wheel is movably connected to the bottom of the guide seat. The outer side of the guide wheel is movably connected to the outer side of the traction steel wire.

[0016] Furthermore, the positioning plate has detachable mounting seats on both the front and rear sides of its middle section. The front and rear sides of the inner wall of the mounting seat are movably connected to the front and rear sides of the mounting seat, respectively. The middle of both mounting seats is fixedly connected to the right end of the traction steel wire. A locking plate is fixedly provided on the top of the mounting seat.

[0017] The front and rear ends of the mounting base are both fixed with mounting grooves that slide with the mounting base. The front and rear parts of the mounting grooves can be detachably engaged with return springs, and the opposite sides of the two return springs are detachably engaged with the left and right sides of the mounting base, respectively.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0020] This utility model provides a discharge mechanism for a continuous quenching device. An electric push rod, a first connecting rod, and a second connecting rod work together to adjust the working height of the positioning plate above the base. The lower slide rail and the lower slide seat enable the second connecting rod to slide on the base, while the upper slide rail and the upper slide seat enable the first connecting rod to slide below the positioning plate. This allows for adjustment of the working height of the roller conveyor line at the discharge side of the chain conveyor line, making it convenient for users to place the tool collection box on the roller conveyor line, reducing the drop height of the workpiece and preventing bumps, scratches, or damage during the drop process.

[0021] This utility model provides a discharge mechanism for a continuous quenching device. The working height between the positioning plate and the base is increased, the limit spring is stretched, and the traction steel wire drives the mounting seat to slide towards the left side of the assembly seat through the guide wheel. This completes the anti-slip groove on the locking plate to squeeze the rollers on the roller conveyor line, completes the braking of the roller conveyor line, and prevents the material box placed on the roller conveyor line to receive workpieces from slipping.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0042] See attached document Figure 1-7 This utility model provides a discharge mechanism for a continuous quenching device, comprising the following structure:

[0043] Oil tank 1, with chain conveyor 2 fixed inside the oil tank 1, the front discharge side of the chain conveyor 2 extending to the front end of the oil tank 1.

[0044] The base 3 has a positioning plate 6 on top of it. The top of the positioning plate 6 is detachably attached to the roller conveyor line 7. The discharge side of the front of the chain conveyor line 2 is directly above the roller conveyor line 7.

[0045] In this embodiment, a receiving frame 11 that cooperates with the discharge side of the tunnel furnace is fixedly provided on the rear side of the oil tank 1. The discharge port of the receiving frame 11 extends to the top rear side of the chain conveyor line 2. The width of the discharge port of the receiving frame 11 is smaller than the width of the chain conveyor line 2. A cover 12 is detachably snapped onto the top of the oil tank 1.

[0046] The receiving rack 11 guides the workpieces that have been quenched in the tunnel furnace to the oil tank 1. The workpieces are then transferred to the oil tank 1 by the chain conveyor line 2. The design of the cover 12 effectively prevents dust in the workshop from falling directly into the oil tank 1.

[0047] In this embodiment, an electric push rod 4 is fixedly provided on the left side of the base 3. The front and rear ends of the left side of the base 3 are movably connected to a first connecting rod 41. The top output end of the electric push rod 4 is movably connected to the middle part of the first connecting rod 41. The middle part of the first connecting rod 41 is movably connected to a second connecting rod 42. The top of the second connecting rod 42 is movably connected to the bottom left side of the positioning plate 6.

[0048] The right end of the base 3 is fixed with a lower slide rail 31 on both the front and rear sides. The top of the lower slide rail 31 is slidably connected to a lower slide seat 32. The top of the lower slide seat 32 is movably connected to the bottom of the second connecting rod 42.

[0049] The electric actuator 4, the first connecting rod 41, and the second connecting rod 42 work together to adjust the working height of the positioning plate 6 above the base 3. The lower slide rail 31 and the lower slide seat 32 enable the second connecting rod 42 to slide on the base 3, while the upper slide rail 61 and the upper slide seat 62 enable the first connecting rod 41 to slide below the positioning plate 6. This adjusts the working height of the roller conveyor line 7 at the front discharge side of the chain conveyor line 2, allowing users to place the tool collection box on the roller conveyor line 7, reducing the drop height of the workpiece and preventing bumps, scratches, or damage during the drop.

[0050] In this embodiment, a positioning seat 5 is fixedly provided at the left end of the base 3, and a limit spring 51 is detachably snapped onto the top of the positioning seat 5. A traction steel wire 52 is fixedly provided on the top of the limit spring 51.

[0051] The working height between the positioning plate 6 and the base 3 increases, the limit spring 51 is stretched, and the traction steel wire 52 drives the mounting seat 81 to slide towards the left side of the assembly seat 8 through the guide wheel 64. This completes the squeezing treatment of the roller on the roller conveyor line 7 by the anti-slip groove on the locking plate 83, and completes the braking treatment of the roller conveyor line 7 to prevent the material box placed on the roller conveyor line 7 to receive the workpiece from slipping.

[0052] In this embodiment, an upper slide rail 61 is fixedly provided on both the front and rear sides of the right end of the positioning plate 6. An upper slide seat 62 is slidably connected to the bottom of the upper slide rail 61. The bottom of the upper slide seat 62 is movably connected to the top of the first connecting rod 41. A guide seat 63 is fixedly provided at the bottom of the left end of the positioning plate 6. A guide wheel 64 is movably connected to the bottom of the guide seat 63. The outer side of the guide wheel 64 is movably connected to the outer side of the traction steel wire 52.

[0053] The working height between the positioning plate 6 and the base 3 is reduced, the limit spring 51 contracts, the traction steel wire 52 loosens, the reset spring 82 on the assembly seat 8 pushes the mounting seat 81 to move, releasing the locking flap from the brake connection of the roller conveyor line 7, and also making it convenient for the user to push the workpiece box on the roller conveyor line 7 onto the trolley for transfer.

[0054] The design of the guide seat 63 and the guide wheel completes the guiding design of the traction steel wire 52, avoiding interference between the traction steel wire 52 and the moving structural parts between the positioning plate 6 and the base 3. The traction combination of the limit spring 51 and the traction steel wire 52 facilitates the user's subsequent maintenance and use.

[0055] In this embodiment, the positioning plate 6 is detachably sleeved with a mounting base 8 on both the front and rear sides of the middle part. The front and rear sides of the inner wall of the mounting base 8 are movably connected to the front and rear sides of the mounting base 81, respectively. The middle parts of the two mounting bases 81 are fixedly connected to the right end of the traction steel wire 52. A locking plate 83 is fixedly provided on the top of the mounting base 81. The top of the locking plate 83 is fitted with an anti-slip groove that mates with the bottom of the roller of the roller conveyor line 7.

[0056] The front and rear ends of the mounting base 8 are both fixed with mounting grooves that slide with the mounting base 81. The front and rear parts of the mounting groove can be detachably snapped with return springs 82. The opposite sides of the two return springs 82 are detachably snapped with the left and right sides of the mounting base 81, respectively.

[0057] The anti-slip groove of the locking plate 83 and the braking action between the rollers of the roller conveyor line 7 effectively prevent the workpiece box from falling off the roller conveyor line 7.

[0058] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
