Description

Technical Field

[0001] The invention relates to the technical field of casting feeding, in particular to material conveying equipment for a die-casting machine. Background Art

[0002] There are two types of die-casting machines: vertical and horizontal. The principle of use is to inject molten liquid into the mold under pressure and cool it into shape. After the mold is opened, a solid casting can be obtained. In casting production, castings always need to undergo cold working before they can be put into normal use. The cooling treatment of castings is the process of allowing the temperature of the castings to drop from a high temperature state to a balance with the ambient temperature. It is usually set in the cooling pipe inside the mold. After the die-casting is completed, the castings are manually taken to the operating platform for the next process.

DETAILED DESCRIPTION

[0039] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0040] like Figures 1 to 6 As shown, a material conveying device for a die-casting machine according to an embodiment of the present invention includes a frame 1, a blanking component, a conveying component and a classification component. The blanking component is used to clamp and discharge castings and perform temperature detection processes through the machine. The conveying component is used to transfer castings and perform roughness detection processes on the surface of castings. The classification component is used to provide a variety of classification transmission paths for the castings being conveyed.

[0041] Specifically, a main control box is provided on one side of the frame 1, and a processor is provided inside, which is not shown in the figure. It is used to input the running program so that the feeding equipment can perform the unloading, detection, and conveying processes according to the program settings. It can also receive and analyze the temperature detection data and the pressure detection data to effectively perform accurate classification processes. The unloading component includes a robot arm 2, which can move in three-dimensional space. The top output end of the robot arm 2 is fixedly connected to the first connecting frame 3, and the lower end of the first connecting frame 3 is provided with a clamping component and a temperature measuring component. The clamping component is used to clamp the casting, and the temperature measuring component is used to perform multiple temperature detections on the casting.

[0042] It should be noted that the first connecting frame 3 can be, but is not limited to, an I-shape, an L-shape, or a triangle shape, which can provide a stable connection. The specific shape can be determined according to the size setting of the top output end of the robot arm 2.

[0043] refer to Figure 1 、 Figure 3The clamping component includes a convex frame 4, which is bolted to the first connecting frame 3. The interior of the convex frame 4 is a hollow structure, and a convex groove can be preferably provided to provide sufficient placement space for the temperature measuring component. The third telescopic part 16 is fixed at both ends of the interior of the convex frame 4, and the output end of the third telescopic part 16 is bolted to the clamping frame 5. The clamping frame 5 can be selected in an appropriate shape according to the shape of the clamped casting to achieve a better clamping effect. A clamping pad 17 is provided on each side of the clamping frame 5, which fits the surface of the casting and is used to increase the clamping stability of the clamping frame 5 on the casting.

[0044] The temperature measuring component includes a linear motor 14 arranged at the top of the convex frame 4. The output end of the linear motor 14 is bolted with a second telescopic part 15. The downward output end of the second telescopic part 15 is fixedly connected with a first temperature sensor. The first temperature sensor adopts non-contact infrared detection technology and can obtain corresponding temperature detection values without contacting the surface of the casting. The first temperature sensor is driven to move by the output end of the linear motor 14 to perform temperature detection at multiple positions on the surface of the casting. The main control box receives the temperature detection value and draws a temperature curve of the clamped casting according to the temperature detection values at multiple positions, which is convenient for subsequent heat dissipation to different degrees according to the temperature conditions of the casting.

[0045] The conveying assembly includes a first conveying part and a second conveying part, wherein the first conveying part is arranged on the upper side of one end of the frame 1 close to the robot arm 2, the first conveying part includes a first roller 6, and the second conveying part includes a third roller 11. Both ends of the first roller 6 and the third roller 11 are connected to the shaft seat with bearings, and the shaft seat bolts are fixed to the frame 1. One end of the first roller 6 and the third roller 11 is fixedly connected to the first driving part and the third driving part respectively. The first driving part and the third driving part can be rotating motors, which are used to drive the first conveying part and the second conveying part to perform the conveying process.

[0046] refer to Figure 2 、 Figure 4, the classification component is arranged in the middle of the frame 1, the classification component includes a first telescopic part 13 fixed to the bottom of the frame 1, the output end bearing of the first telescopic part 13 is connected to the support plate 18, the upper surface of the support plate 18 is away from the first conveying part at two right angles and fixedly connected to the fourth telescopic part 23, and the two right angles close to the first conveying part are fixedly connected to the fifth telescopic part 24, the classification component also includes a distribution table 8, a cylindrical block is fixed in the middle of the lower surface of the distribution table 8, and a group of first hinge blocks and a group of second hinge blocks are respectively provided on the surface of the cylindrical block facing the support plate 18. The first hinge block corresponds to the setting position of the fourth telescopic part 23 and is hinged to its output end, and the second hinge block is arranged at the setting position of the fifth telescopic part 24. The position corresponds to the position and is hinged to its output end. A first slide groove 25 is provided on the surface of the cylindrical block where the second hinge block is set. The first slide groove 25 is slidably connected to the second hinge block. A first spring 26 is provided inside the first slide groove 25. The two ends of the first spring 26 are respectively fixedly connected to the second hinge block and the inner wall of the first slide groove 25. When the output end of the fifth telescopic part 24 drives the second hinge block to rise a distance greater than the rising distance of the output end of the fourth telescopic part 23, the output end of the fourth telescopic part 23 rotates with the first hinge block, and the first spring 26 is compressed and the second hinge block drives the cylindrical block and the distribution platform 8 to tilt, thereby realizing the angle tilt of the distribution platform 8, which is convenient for the casting located above the distribution platform 8 to slide and transport.

[0047] A second gear 22 is fixed to the outer surface of the cylindrical block, and one side of the second gear 22 is meshed with the first gear 21. A rotary drive motor 19 is provided below the first gear 21, and the output end of the rotary drive motor 19 is fixed through the middle of the first gear 21. The lower surface of the rotary drive motor 19 is fixedly connected to a second connecting frame 20, and the other end of the second connecting frame 20 is bolted to the lower surface of the distribution platform 8. When the rotary drive motor 19 is started, the first gear 21 drives the second gear 22 to rotate, thereby driving the cylindrical block and the distribution platform 8 to rotate, thereby realizing the distribution platform 8 to transmit castings in different directions.

[0048] Furthermore, the rotary drive motor 19 is fixed to the distribution platform 8 through the second connecting frame 20, so that when the distribution platform 8 is tilted, the distribution platform 8 drives the second connecting frame 20 and the rotary drive motor 19 to tilt synchronously, so that the first gear 21 and the second gear 22 remain in a meshing state.

[0049] A group of second rollers 10 are arranged above the distribution platform 8. Both ends of the second rollers 10 are also connected to shaft seats with bearings. The shaft seats are bolted to the distribution platform 8. One end of the second roller 10 is fixedly connected to the second driving part, and the second driving part is also fixed to the distribution platform 8. The left side of the third roller 11 is set as the first classification area for the next processing step. When the first telescopic part 13 drives the distribution platform 8 to rise between the first conveying part and the second conveying part, when the first driving part, the second driving part and the third driving part are all started, the castings are sequentially conveyed from the first conveying part, the second roller 10 and the third roller 11. This is the first conveying state.

[0050] A second temperature sensor is fixedly mounted on the distribution table 8 located on the right side of the second rotating roller 10 and is used to detect the surface temperature of the casting after the heat dissipation process. The second temperature sensor can be contact or non-contact.

[0051] In this application, the rotary drive motor 19 is set to be a bidirectional rotating motor, and the rotary drive motor 19 is set to be in an initial non-starting state. Figure 1 , the distribution platform 8 is lowered to Figure 1 Position, the third driving part is started, and the casting is conveyed to the left. When the output end of the rotary drive motor 19 rotates 90 degrees clockwise, the casting is conveyed forward. When the output end of the rotary drive motor 19 rotates 90 degrees counterclockwise, the casting is conveyed backward. The second classification area, the third classification area, and the fourth classification area are sequentially arranged on the left side and the front and rear sides of the frame 1, and the states of conveying to the second classification area, the third classification area, and the fourth classification area are defined as the second conveying state, the third conveying state, and the fourth conveying state, respectively.

[0052] In the present invention, the feeding equipment is arranged on one side of the die-casting machine. After the casting of the die-casting machine is formed, the casting is ejected from the mold, and the clamping parts are positioned to both sides of the casting by the robot arm 2, and the casting is clamped. Finally, the casting is clamped to the first conveying part, and the length and external shape of the clamped part of the casting are input in advance in the main control box. The third telescopic part 16 adjusts the extension length according to the length of the clamped part to prevent the extension length from being too low, resulting in loose clamping, or the extension length from being too large, resulting in deformation of the casting surface.

[0053] During the process of the casting being clamped and conveyed to the first conveying part, the number of temperature detections is pre-set in the main control box. According to the set number of temperature detections c and the length dimension L of the clamped part, the linear motor 14 drives the second telescopic part 15 and the first temperature sensor to move. The specific movement rules are as follows: the first temperature sensor moves to the end where the casting is clamped, and takes this end as the starting end to perform detections in sequence. Then, it moves at a distance of L / (c-1) and performs temperature detection on the casting. Therefore, the other end where the casting is clamped is the end point. In addition, through the setting of the second telescopic part 15, the first temperature sensor maintains the same detection distance with the detected part on the surface of the casting to improve the accuracy of data acquisition.

[0054] Specifically, a temperature curve is drawn based on the number of temperature detections c and the temperature detection value obtained each time, which is recorded as T i -c curve, set the ideal temperature value when the casting is taken out to T0, T i is the temperature value detected by the first temperature sensor during the i-th detection, i is an integer between 1 and c, and the processor calculates T i And T0 are compared and judged to implement different degrees of heat dissipation measures, namely:

[0055] P1: When T i When all values are not greater than T0, it indicates that the casting has reached the ideal conveying temperature, so the main control box controls the implementation of the first conveying state;

[0056] P2: When T i When all are greater than T0, it means that the surface temperature of the casting is too high and it is difficult to reach the ideal conveying temperature under the air cooling effect within the set time. Special cooling treatment is required. Therefore, the main control box controls the implementation of the second conveying state. The second classification area can be set as a water cooling area to use water cooling to cool the casting.

[0057] P3: When T i If there is a temperature value greater than T0, it means that the cooling temperature distribution on the casting surface is uneven, and a supplementary air cooling process is required to reduce the temperature. Therefore, the cooling process of the first conveying part is performed first.

[0058] P4: During the period when the first conveying part transfers the casting to the second roller 10, the second temperature sensor detects and measures the temperature according to the detected temperature value T j Determine whether the ideal delivery temperature is reached, that is, T j If the values are not greater than T0, the first conveying state in the P1 process is continued, and the detection times of the second temperature sensor are preset, where j is the serial number of the detection times;

[0059] If T jIf there is a temperature detection value greater than T0, the main control box controls the implementation of the third conveying state. The transmission path shows that the surface temperature distribution of the casting is still uneven. Without delaying the subsequent casting transmission process, it enters the third classification area and can be further cooled by equipment such as blowers.

[0060] refer to Figure 5 、 Figure 6 The outside of the first roller 6 is slidably connected to the sleeve 7, and the interior of the first roller 6 is a hollow structure. The surfaces of the first roller 6 and the sleeve 7 are respectively provided with a plurality of first through holes 27 and a plurality of second through holes 33. It should be noted that when the first roller 6 is in a stationary state, the first through holes 27 and the second through holes 33 are provided in one-to-one correspondence, and the diameter length of the first through holes 27 is greater than the diameter length of the second through holes 33. A connecting hole 30 is provided at one end of the first roller 6 away from the first driving part, and a through pipe 9 is connected to the bearing inside the connecting hole 30. A pressure sensor 31 and a control valve are installed on the through pipe 9. The other end of the through pipe 9 is connected to the pump body 12, and the pump body 12 is configured as an air pump.

[0061] The two ends of the sleeve 7 are clamped with the two ends of the first roller 6, and fixed blocks 32 and second slide grooves 28 are provided inside the two ends of the first roller 6. One side of the fixed block 32 is fixedly connected to the second spring 29, and the other end of the second spring 29 is fixed to the sleeve 7. The two ends of the sleeve 7 located inside the first roller 6 are respectively slidably connected to the second slide grooves 28;

[0062] The spring coefficient of the second spring 29 is determined by the gravity of the casting, the roughness of its surface, and the rotational speed of the first driving part. That is, the heavier the casting and the rougher the surface, the larger the spring coefficient of the second spring 29 is selected, so that when the casting is transferred, the first through hole 27 and the second through hole 33 of the sleeve 7 remain in a connected state under the action of the spring force of the second spring 29.

[0063] In the present application, when the first conveying state is executed, the first driving unit, the second driving unit, and the third driving unit drive the first rotating roller 6, the second rotating roller 10, and the third rotating roller 11 to rotate synchronously;

[0064] When executing the second conveying state, the first driving unit and the second driving unit drive the first roller 6 and the second roller 10 to rotate synchronously. When the casting completely enters the distribution table 8, the first telescopic unit 13 drives the distribution table 8 to descend. In order to transport the casting from the distribution table 8 to the second classification area, the angle of the distribution table 8 can be tilted or the second roller 10 can be continued to convey.

[0065] The cooling process of the first conveying portion in P3 is specifically as follows: when the casting is conveyed, the pump body 12 is started, the control valve is opened, and the external air flows through the pump body 12, the through pipe 9, the connecting hole 30, the first through hole 27, and the second through hole 33 to perform a supplementary air cooling process on the casting conveyed above. In addition, since the diameter length of the first through hole 27 is larger than the diameter length of the second through hole 33, the temperature of the air flow can be reduced when passing through this area, thereby improving the cooling effect on the casting. When the first through hole 27 and the second through hole 33 are in a communicating state and the pump body 12 is running at the set initial power W, the ideal pressure value detected by the pressure sensor 31 is F;

[0066] Since the roughness of the casting surface may vary during casting, this will cause the sleeve 7 to deflect around the first roller 6, the second spring 29 to be compressed, and the first through hole 27 and the second through hole 33 to overlap slightly. Then, when the airflow passes through the first through hole 27 and the second through hole 33, the flow velocity will increase. When the flow velocity increases, the heat dissipation effect is improved. In this case, the real-time pressure value fs detected by the pressure sensor 31 is ≥ F. The pressure limit value detected by the pressure sensor 31 when the first through hole 27 and the second through hole 33 are just not flowing with air is recorded as fmax, where fmax is much larger than fs.

[0067] Specifically, in P3, when T i When there is a temperature greater than T0, further:

[0068] If there are T less than 50% of the time i >T0, indicating that the excessive temperature detected on the casting surface is small, the pump body 12 is set to operate at the set initial power W, otherwise the actual operating power of the pump body 12 will be based on the specific T i >T0, for example, by using the gear selection method, when T i > When the number of times T0 is between 50% and 70% and does not include 50%, the actual operating power of the pump body 12 is 1.5W. i >When the number of times T0 is between 70% and 100% and does not include 70% and 100%, the actual operating power of the pump body 12 is 2W;

[0069] During the above cooling process, if all the pressure sensors 31 detect fmax during the conveying process, it means that the surface roughness of the casting is large, the cooling process is stopped, the pump body 12 is turned off, and the fourth conveying state is executed. The casting is input into the fourth classification area. Precision instruments can be used to perform individual roughness precision detection to achieve roughness detection of the castings during the conveying process, thereby judging the casting quality;

[0070] If some but not all pressure sensors 31 detect fmax, the rotation speed of the first drive unit is reduced in combination with the discharge speed of the next casting to ensure that the first through hole 27 and the second through hole 33 can spray air to continuously cool the surface of the casting, and then the P4 process is executed.
