Description

Technical Field

[0001] The invention relates to the technical field of cylinder liner conveying, and in particular to a turnover conveying cooling device for cylinder liner heating treatment. Background Art

[0002] As an internal kit of an automobile engine, the cylinder liner needs to withstand high temperature and high pressure environment when it is in use. Its inner wall needs to produce increased high-speed friction with accessories such as piston rings, and the outside of the cylinder liner also needs to be cooled. Therefore, the cylinder liner is in an environment with a large temperature difference during operation. Therefore, the cylinder liner must have high heat resistance and wear resistance during production. For this reason, it needs to be heat treated after casting during production to improve the heat resistance and wear resistance of the cylinder liner. After heat treatment, it still needs to be processed subsequently. In order to speed up the subsequent process, there is no need to wait for the cylinder liner to cool before processing. A special conveying cooling device is often used to quickly cool the cylinder liner during conveying, so as to speed up the subsequent processing process. In order to avoid the cylinder liner being damaged due to excessive cooling speed, the common conveying cooling device mostly installs a cooling fan for air cooling, so that the cylinder liner can be gradually cooled by air during conveying.

[0003] When the common cylinder liner heating treatment conveying and cooling device is in use, the cylinder liner may be cooled down to a certain extent while conveying the cylinder liner. In order to avoid the cylinder liner cooling speed being too fast and affecting the cylinder liner quality, multiple sets of cooling fans are often installed on the conveyor belt to cool down and convey the cylinder liner after heating treatment by air cooling. After the cylinder liner after high-temperature heating treatment is placed on the conveyor belt, it is cooled down by cold wind during the conveying process. The common cylinder liner heating treatment conveying and cooling device has a good conveying effect when in use, but there are still some problems: When the common cylinder liner heating treatment conveying cooling device is in use, due to the large overall volume of the cylinder liner, the traditional cooling fan blowing cooling method can mostly only cool one side of the cylinder liner, while the back side often cannot be effectively cooled, resulting in limited cylinder liner cooling area and low cooling efficiency. Summary of the invention

[0004] The object of the present invention is to provide a turnover type conveying and cooling device for cylinder liner heating treatment, so as to solve the defect of limited cooling effect of the existing cylinder liner heating treatment conveying and cooling device.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a flip-type conveying and cooling device for cylinder liner heating treatment, comprising a main frame and a side frame, a control panel is installed at one end of the main frame, a chain plate conveyor belt is arranged inside the main frame, both ends of the top of the main frame are fixedly connected to the side frames, one side of the top of the main frame is flipped and connected to a feeding structure, the upper part of the inner side of the side frame is rotatably connected to a top plate, a cooling fan is installed at the top of the top plate, and the lower part of the inner side of the side frame is rotatably connected to a flip mechanism, the flip mechanism comprises a flip frame, a guide groove, a ball, an electric telescopic rod, a push rod, a guide groove, a sliding block and a lifting block, the flip frame is flipped and connected to the lower part of the inner side of the side frame, and adjustment structures are arranged at both ends of the top plate.

[0006] When in use, when the conveying and cooling device is in use, the cylinder liner after the heating treatment is conveyed along the chain plate conveyor belt, and during the conveying process, the cooling fan generates heat dissipation wind, thereby air-cooling the cylinder liner for rapid cooling, lowering the temperature and conveying.

[0007] Preferably, the cooling fans are evenly spaced above the chain conveyor belt, so that the cylinder liner is cooled by the fans when it moves above the chain conveyor belt, and the evenly spaced cooling fans can quickly blow away the heat of the cylinder liner.

[0008] Preferably, the unloading structure includes a push plate, a guide rod, a two-way threaded rod, an internally threaded sleeve, a support hinge rod and a pulley. The push plate is flipped and connected to one side of the top of the main frame. A guide rod is provided below the push plate, and a two-way threaded rod is provided above the guide rod. The outer side of the two-way threaded rod is wrapped with an internally threaded sleeve. The top end of the internally threaded sleeve is hinged with a support hinge rod, and one end of the support hinge rod is hinged with a pulley. The cylinder sleeve is made to slide into the top of the chain conveyor belt by flipping the push plate to avoid safety accidents caused by manual operation.

[0009] Preferably, the bidirectional threaded rod and the inner side of the main frame are in a rotating structure, and the bidirectional threaded rod and the internal threaded sleeve are in a threaded connection structure. Since the two groups of internal threaded sleeves are hinged to the same pulley through the supporting hinge rod, when the two groups of internal threaded sleeves move in opposite directions, the pulley can move up and down, and the inner wheel of the pulley can roll. After the pulley moves up, the push plate can be lifted up and flipped to a certain angle, thereby causing the cylinder sleeve at the top of the push plate to slide down.

[0010] Preferably, the guide rod and the internal threaded sleeve are in a sliding structure, and the internal threaded sleeves are evenly spaced on the outside of the guide rod, so that multiple sets of pulleys can be moved up to make the flipping of the push plate smoother, and the pulleys can roll on their own, which will also reduce the wear between the pulleys and the push plate due to excessive friction.

[0011] A plurality of reverse threads are provided on the surface of the bidirectional threaded rod, and each reverse thread is threadedly connected to two sets of internal threaded sleeves. When the bidirectional threaded rod rotates, the plurality of internal threaded sleeves move in the opposite direction at the same time, so that the plurality of pulleys can steadily push the push plates upward.

[0012] Preferably, guide grooves are provided at both ends of the flip frame, balls are wrapped inside both ends of the flip frame, electric telescopic rods are installed at both ends of the side frame, both ends of the flip frame penetrate to the outside of the side frame and are fixedly connected to one end of the push rod, and a guide groove is provided at the other end of the push rod, a slider is slidably connected inside the guide groove, a lifting block is fixedly connected to the outer wall of the chain conveyor belt, and the cylinder sleeve is cooled on both sides by flipping it.

[0013] Preferably, the lower part of the inner side of the flip frame and the side frame is in a flip structure, and the guide grooves are evenly spaced inside the flip frame, so that the lifting block can pass through the inside of the guide groove. At this time, the cylinder sleeve located on the inner side of the flip frame can be lifted by the lifting block and the conveying ball can roll by itself, thereby reducing the wear between the flip frame and the chain conveyor belt.

[0014] Preferably, the balls are distributed at equal intervals inside the turning frame, so as to avoid excessive friction between the turning frame and the chain conveyor belt. As the chain conveyor belt conveys, the lifting block can stably support the cylinder sleeve for transportation.

[0015] Preferably, the sliding block and one side of the electric telescopic rod are in a rotating structure, and the lifting blocks are distributed at equal intervals on the outer wall of the chain conveyor belt, so that a certain gap exists between the cylinder sleeve and the chain conveyor belt during transportation.

[0016] Preferably, the electric telescopic rods are symmetrically distributed at both ends of the turning frame, and the guide groove and the slider are in a sliding structure, so that the push rod can drive the turning frame to turn over, thereby driving the cylinder liner to turn over and cool down.

[0017] After the turning frame is installed, the opening position of the guide groove corresponds to the distribution position of the lifting blocks, and the lifting blocks can pass through the inside of the guide groove before and after the turning frame is turned over. Since there are many lifting blocks, when the cylinder sleeve is placed above the chain conveyor belt, it will be lifted by the lifting blocks, so that there is a certain gap between it and the surface of the chain conveyor belt, so that the cylinder sleeve can slide smoothly into the inside of the turning frame when it moves.

[0018] Preferably, the adjustment structure includes an arc groove, a fastening screw and a fastening handle, the arc groove is opened inside the side frame, and both ends of the top plate are fixedly connected with fastening screws, one end of the outer wall of the fastening screw passes through the outside of the arc groove and is connected to the internal thread of the fastening handle, and the blowing angle of the cooling fan can be adjusted by adjusting the top plate to flip it at a certain angle, so that the pipe sleeve can be cooled by blowing air at various angles.

[0019] Preferably, the fastening screws are symmetrically distributed at both ends of the top plate, and the fastening screws and the fastening handles are in a threaded connection structure, and the top plate can be kept stable by tightening the fastening handles.

[0020] Due to the irregular surface of some cylinder liners, the direct blowing method of the cooling fan often cannot cool the cylinder liners more comprehensively. For this reason, the cooling area of ​​the cylinder liners can be increased by adjusting the blowing angle of the cooling fan.

[0021] Compared with the prior art, the utility model has the following beneficial effects: the push plate can be turned over by the motor drive and the cylinder sleeve on its top can be slid into the top of the chain plate conveyor belt without manual pushing; at the same time, when the cylinder sleeve is conveyed to the turning frame, the turning frame can drive the cylinder sleeve to turn over under the drive of the electric telescopic rod, so that both sides of the cylinder sleeve can be cooled; 1. As the lifting blocks are distributed on the outer wall of the chain conveyor belt, there will be a large gap between the cylinder sleeve and the chain conveyor belt, which will cause the cylinder sleeve to gradually slide into the inner side of the turning frame during transportation. At this time, the electric telescopic rod is started to push the slider to slide along the inside of the guide groove, and the push rod gradually drives the turning frame to turn over. At this time, the cylinder sleeve can be turned over and cooled during transportation; 2. The motor drives the bidirectional threaded rod to make the corresponding two groups of internal threaded sleeves move in opposite directions, and thereby push the pulley upward through the supporting hinge rod, so that the push plate can be flipped, and the cylinder sleeve placed on the top of the push plate can slide into the top of the chain conveyor belt for transportation without manual pushing.

[0022] 3. Flip the top plate on the rotating structure of the side frame and the top plate to adjust the blowing angle of the cooling fan and tighten the handle so that the cooling fan can blow cooling at various angles according to the irregular surface of the cylinder liner.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0026] See also Figure 1-Figure 8 The present invention provides a flip-type conveying cooling device for cylinder liner heating treatment, comprising a main frame 1 and a side frame 4, a control panel 2 is installed at one end of the main frame 1, a chain plate conveyor belt 3 is arranged inside the main frame 1, both ends of the top of the main frame 1 are fixedly connected to the side frames 4, a top plate 5 is rotatably connected to the upper inner side of the side frame 4, a cooling fan 6 is installed at the top of the top plate 5, and the cooling fans 6 are evenly spaced above the chain plate conveyor belt 3. A feeding structure 7 is flipped and connected to one side of the top of the main frame 1, and the feeding structure 7 comprises a push plate 701, a guide rod 702, a bidirectional threaded rod 703, an internal threaded sleeve 704, a support hinge rod 705 and a pulley 70 6. The push plate 701 is flipped and connected to one side of the top of the main frame 1. A guide rod 702 is arranged below the push plate 701, and a bidirectional threaded rod 703 is arranged above the guide rod 702. The outer side of the bidirectional threaded rod 703 is wrapped with an internal threaded sleeve 704. The top of the internal threaded sleeve 704 is hinged with a support hinge rod 705, and one end of the support hinge rod 705 is hinged with a pulley 706. The bidirectional threaded rod 703 and the inner side of the main frame 1 are in a rotating structure, the bidirectional threaded rod 703 and the internal threaded sleeve 704 are in a threaded connection structure, the guide rod 702 and the internal threaded sleeve 704 are in a sliding structure, and the internal threaded sleeves 704 are evenly distributed on the outer side of the guide rod 702.

[0027] See attached Figure 1 , Figure 2 , Figure 3 and Figure 4When the device is used, the heated cylinder sleeve will be grabbed by professional equipment such as a mechanical arm and placed on the top of the push plate 701. At this time, the motor is started to drive the bidirectional threaded rod 703 to rotate. Since a number of reciprocating threads are arranged on the outer side of the bidirectional threaded rod 703, and each set of threads is connected to two sets of internal threaded sleeves 704 with corresponding threads, when the bidirectional threaded rod 703 rotates, the corresponding two sets of internal threaded sleeves 704 will move in the opposite direction along the guide rod 702, and thereby push the pulley 706 upward through the support hinge rod 705. Since the push plate 701 is close to the chain plate One end of the conveyor belt 3 is in a flipping structure with the main frame 1. As the pulley 706 pushes upward, the push plate 701 flips a certain angle and the cylinder sleeve slides along the push plate 701 into the top of the chain conveyor belt 3 for transportation, thereby avoiding the low efficiency of manual pushing. As the cylinder sleeve slides into the top of the chain conveyor belt 3, the cylinder sleeve is gradually transported along the chain conveyor belt 3, and during the transportation process, the cooling fan 6 is started to blow air in the direction of the chain conveyor belt 3. As the cylinder sleeve moves, it is gradually cooled by the cold air blown by the cooling fan 6, so that the cylinder sleeve is gradually cooled during the transportation process.

[0028] The lower part of the inner side of the side frame 4 is rotatably connected with a flip mechanism 8, which includes a flip frame 801, a guide groove 802, a ball 803, an electric telescopic rod 804, a push rod 805, a guide groove 806, a slider 807 and a lifting block 808. The flip frame 801 is flip-connected to the lower part of the inner side of the side frame 4. Both ends of the flip frame 801 are provided with guide grooves 802. Both ends of the flip frame 801 are wrapped with ball 803. Both ends of the side frame 4 are installed with an electric telescopic rod 804. Both ends of the flip frame 801 penetrate to the outer side of the side frame 4 and are fixedly connected to one end of the push rod 805. The other end of the push rod 805 is opened. A guide groove 806 is provided, and a slider 807 is slidably connected inside the guide groove 806. A lifting block 808 is fixedly connected to the outer wall of the chain conveyor belt 3. The turning frame 801 and the lower inner side of the side frame 4 are in a turning structure. The guide grooves 802 are evenly distributed inside the turning frame 801, and the balls 803 are evenly distributed inside the turning frame 801. The slider 807 and one side of the electric telescopic rod 804 are in a rotating structure. The lifting blocks 808 are evenly distributed on the outer wall of the chain conveyor belt 3, and the electric telescopic rods 804 are symmetrically distributed at both ends of the turning frame 801. The guide groove 806 and the slider 807 are in a sliding structure.

[0029] See attached Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8When the conveying cooling device is used, since the cylinder liner is relatively large as a whole, the effect of air cooling on a single side is limited. Therefore, the cylinder liner needs to be turned over during the conveying process so that both sides of the cylinder liner can be cooled by air. Since a number of lifting blocks 808 are fixed to the outer wall of the chain conveyor belt 3, when the cylinder liner slides into the top of the chain conveyor belt 3 for conveying, there will be a large gap between the cylinder liner and the chain conveyor belt 3, so that the cylinder liner gradually slides into the inner side of the flip frame 801 during conveying. At this time, the operator can start the electric telescopic rod 804 through the control panel 2. At this time, one side of the electric telescopic rod 804 extends and pushes the slider 807 to slide along the inner side of the guide groove 806. Since the push rod 805 is connected to the turning frame 801, when the slider 807 moves, the push rod 805 gradually drives the turning frame 801 to turn over, and thereby drives the cylinder sleeve located on the inner side of the turning frame 801 to turn over together. When the turning frame 801 turns over 90 degrees, the lifting block 808 will drive the cylinder sleeve to be transported along the chain plate conveyor belt 3 again. At this time, the cylinder sleeve is cooled by the cooling fan 6 on both sides during the transportation process. After the cylinder sleeve is turned over, the operator starts the electric telescopic rod 804 in the reverse direction through the control panel 2, so that one side of the electric telescopic rod 804 pulls the slider 807 to shrink, so that the turning frame 801 can be reset after turning over to wait for the subsequent cylinder sleeve cooling and transportation.

[0030] Adjustment structures 9 are provided at both ends of the top plate 5, and the adjustment structure 9 includes an arc groove 901, a fastening screw 902 and a fastening handle 903. The arc groove 901 is opened inside the side frame 4, and the two ends of the top plate 5 are fixedly connected with the fastening screw 902. One end of the outer wall of the fastening screw 902 passes through the outside of the arc groove 901 and is connected with the internal thread of the fastening handle 903.

[0031] See attached Figure 1 and Figure 3 In the process of cooling the cylinder liner, due to the irregular surface of some cylinder liner, the cooling fan 6 blowing directly downward may not be able to effectively cool the irregular part of the cylinder liner. Therefore, during cooling and conveying, the angle of the top plate 5 can be adjusted according to the situation, so that the blowing angle of the cooling fan 6 can be adjusted, so that the cooling fan 6 can effectively blow air to cool the surface of the cylinder liner. During adjustment, since the side frame 4 and the top plate 5 are in a rotating structure, the fastening screw 902 slides along the arc groove 901. When the angle is adjusted to the appropriate position, tighten the fastening screw 902 and the fastening handle 903. At this time, the cylinder liner conveyor surface will be cooled by blowing air at various angles.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
