Description

Technical Field

[0001] The present invention relates to the field of forging technology, and in particular to a material arm and a use method thereof, as well as a conveying device and a use method thereof. Background Art

[0002] Existing technology generally involves cutting forging bars (copper or aluminum bars) and heating them with a flame or in a medium-high frequency heating furnace. The cut, heated bars are then gripped manually or with a cylinder gripper and placed into a mold for forging and forming. Manual loading with existing technology presents a harsh environment, low production efficiency, and is subject to human interference during operation (e.g., operating time, bar cooling), resulting in inconsistent bar temperatures within the mold, impacting product quality consistency. Using a cylinder gripper for loading requires the two molds to be opened before the cylinder can enter. This requires a large opening distance, which increases mold opening and closing times and affects production efficiency. The heated copper bars must be kept within a certain distance from the molds, and the cylinders and other components operate in a harsh and high-temperature environment. Cylinders, sensors, and air pipes frequently damage and require frequent replacement, resulting in high production costs. If the cylinder gripper's placement of the bars deviates, the bars cannot be removed in a timely manner, potentially damaging the molds and even the equipment. The bar loading device adopts a servo motor to drive the synchronous belt. The clamping arm fixed on the synchronous belt is relatively long. The servo motor, synchronous belt, etc. are isolated from the heated bar and mold and are not in the same space, which reduces the impact of high temperature, graphite oil, etc. on components, reduces the replacement frequency, ensures the life of supporting components, and effectively reduces production costs; the operation speed is fast, and the actual production measurement, feeding and returning process are within 2 seconds, which improves production efficiency; mechanical limit is adopted after it is in place, which effectively ensures the stability of the clamping and discharge position; the designed feeding arm head groove coincides with the mold groove after it is in place, ensuring that the bar can be completely placed in the mold, otherwise the bar will be brought back when the feeding arm returns, avoiding damage to the mold and equipment; finally, the whole process is completed automatically inside the equipment, reducing human labor intensity and heat radiation impact, and is relatively environmentally friendly.

[0060] The third driving mechanism drives the feed arm to move along the first direction from the second position to the first position.

[0065] Compared with the prior art, the ejector rod of the present invention moves relative to the accommodating portion to approach or move away from the accommodating portion, presses the material contained in the accommodating portion tightly through the first end of the ejector rod, and drives the ejector rod to move through the second end of the ejector rod opposite to the first end of the ejector rod. This material arm is not only suitable for taking and placing copper rods, but also for taking and placing other high-temperature materials. The first end of the ejector rod is in a high-temperature harsh environment. Since the ejector rod is driven to move by the second end of the ejector rod opposite to the first end of the ejector rod, if there are components such as cylinders and air pipes that drive the ejector rod, as well as sensors, they can all be set at the second end of the ejector rod to drive the ejector rod to move. The length of the ejector rod is not limited and can be set as needed. In this way, the cylinder, air pipe and sensor at the second end of the ejector rod can be kept away from the harsh high-temperature environment, thereby extending the service life of these components. This solves the technical problem in the prior art that components such as cylinders, air pipes and sensors that are not adapted to the harsh high-temperature environment are frequently damaged due to the harsh high-temperature environment, thereby resulting in high production costs.

[0078] The present invention will be further described below with reference to the accompanying drawings.

[0079] like Figure 1-Figure 4 As shown, this embodiment provides a material arm 13, which includes a accommodating portion 200 and a ejecting rod 1306. The ejecting rod 1306 can move relative to the accommodating portion 200 to approach or move away from the accommodating portion 200. The accommodating portion 200 is used to accommodate materials. The first end of the ejecting rod 1306 is used to press tightly against the material accommodated in the accommodating portion 200, and the ejecting rod 1306 is driven to move by the second end of the ejecting rod 1306 opposite to the first end of the ejecting rod 1306.

[0080] In the material arm 13 of this embodiment, the ejecting rod 1306 moves relative to the accommodating portion 200 to approach or move away from the accommodating portion 200, and the material contained in the accommodating portion 200 is pressed tightly by the first end of the ejecting rod 1306, and the ejecting rod 1306 is driven to move by the second end of the ejecting rod 1306 opposite to the first end of the ejecting rod 1306. The material arm 13 is not only suitable for taking and placing copper rods, but also for taking and placing other high-temperature materials. The first end of the ejector rod 1306 is in a harsh high-temperature environment. Since the ejector rod 1306 is driven to move by the second end opposite to the first end of the ejector rod 1306, if there are components and sensors such as cylinders and air pipes that drive the ejector rod 1306, they can all be set at the second end of the ejector rod 1306 to drive the ejector rod 1306 to move. The length of the ejector rod 1306 is not restricted and can be set as needed. In this way, the cylinder, air pipe and sensor at the second end of the ejector rod 1306 can be kept away from the harsh high-temperature environment, thereby extending the service life of these components, and well solving the technical problem in the prior art that components such as cylinders, air pipes and sensors that are not adapted to the harsh high-temperature environment are frequently damaged due to the harsh high-temperature environment, thereby resulting in high production costs.

[0081] The material in this embodiment is a bar 15 for forging, which can be a copper bar.

[0082] The first end of the ejector rod 1306 is configured with an inclined surface 1306a. Figure 3As shown, the direction perpendicular to the inclined surface 1306a and away from the ejector rod 1306 is toward the accommodating portion 200. This structure allows the ejector rod 1306 to apply a force toward the accommodating portion 200 to the material when it is pressed against the material to prevent the material from escaping from the accommodating portion 200 under interference from external factors.

[0083] The direction of movement of the ejector pin 1306 is the length direction of the ejector pin 1306. When the material arm 13 using this structure feeds the bar 15 into the groove of the lower mold 16 of the mold in a direction perpendicular to the direction of mold opening, this structure ensures that the space occupied by the accommodating portion 200 and the ejector pin 1306 near the first end of the ejector pin 1306 along the direction of mold opening does not change due to the movement of the ejector pin 1306. Therefore, the increase in the length of the ejector pin 1306 does not increase the mold opening distance, thereby extending the mold opening and closing time and reducing production efficiency. The mold opening distance is not affected by the length of the ejector pin 1306, and the mold opening and closing time and production efficiency are not affected by the length of the ejector pin 1306. Therefore, the length of the ejector pin 1306 can be selected based on the actual need to avoid the influence of high temperature and harsh environment without affecting the mold opening and closing time and production efficiency. Furthermore, when the material arm 13 of this structure is used to feed the bar 15 into the groove of the mold in a direction perpendicular to the direction of mold opening, the part entering the mold is the accommodating portion 200 and the first end of the ejector rod 1306, and the second end of the ejector rod 1306 can be away from the mold. If there are components such as a cylinder, an air pipe, and a sensor at the second end of the ejector rod 1306, these components are away from the mold and do not enter the mold. Combined with the fact that the moving direction of the ejector rod 1306 is the length direction of the ejector rod 1306, the mold opening distance can be greatly reduced compared to the mold opening distance in the prior art, thereby reducing the time for mold opening and closing and improving production efficiency. Figure 5 and Figure 9 As shown, the figure shows the state in which the material arm 13 extends into the mold to feed the bar material 15 into the groove of the lower mold 16 of the mold.

[0084] The material arm 13 of this embodiment further includes a tightening mechanism connected to the second end of the ejector rod 1306. The tightening mechanism of this embodiment includes a fixed seat 1309 and a movable device connected to the fixed seat 1309, and the movable device includes an elastic member 1308, a linkage block 1307, and an actuator 1310.

[0085] The arrangement of the pressing mechanism enables the ejector rod 1306 in the material arm 13 to be pushed to the extreme position close to the accommodating portion 200 by the pressing mechanism without external force pushing or interfering with the pressing mechanism, such as Figure 1 and Figure 2As shown, at this time, the material arm 13 does not pick up the bar material; or, the ejector rod 1306 in the material arm 13 is pushed toward the accommodating portion 200 by the pressing mechanism to press the bar material 15 accommodated in the accommodating portion 200 tightly, as shown in FIG. Figure 4 shown.

[0086] The feed arm 13 of this embodiment further includes a main body 1305, on which the receiving portion 200 is constructed. A fixed seat 1309 of the clamping mechanism is fixedly connected to the main body 1305, and a movable device is connected to the second end of the feed rod 1306. This structure uses the movable device to push the feed rod 1306 to move, and the fixed seat 1309 provides the clamping force.

[0087] Specifically, one end of the elastic member 1308 of the movable device abuts against the fixed seat 1309, and the other end of the elastic member 1308 of the movable device abuts against the linkage block 1307 of the movable device. The linkage block 1307 is connected to the second end of the ejector rod 1306. This structure can push the linkage block 1307 under the elastic force of the elastic member 1308 to drive the ejector rod 1306 to move toward the accommodating portion 200, thereby tightening the bar 15 accommodated in the accommodating portion 200. Preferably, the elastic member 1308 can be a spring, the linkage block 1307 can be provided with a tightening mounting cavity, the fixed seat 1309 penetrates the tightening mounting cavity and is fixedly connected to the main body 1305, and the elastic member 1308 is disposed in the tightening mounting cavity and abuts against the inner wall of the tightening mounting cavity. The two ends of the spring can be fixed to corresponding abutting surfaces respectively.

[0088] The main body 1305 is configured with an inner cavity, in which the ejector rod 1306, the linkage block 1307, the elastic member 1308, and the fixing seat 1309 are all located. If a limit block 1304 is also provided, the limit block 1304 is also located in the inner cavity. Preferably, the main body 1305 may include a front cover plate 1302 and a rear cover plate 1303, and the inner cavity of the main body 1305 is enclosed by the front cover plate 1302 and the rear cover plate 1303.

[0089] The actuator 1310 of the movable device is located outside the inner cavity of the main body 1305 and is connected to the linkage block 1307. This structure facilitates the external drive unit, such as the first drive unit and the second drive unit on the conveyor device, to drive the actuator 1310 to move the linkage block 107 and then drive the ejector rod 1306 to move.

[0090] A cam bearing 1311 is provided on the actuator 1310 . The cam bearing 1311 is used to contact the first drive unit or the second drive unit, thereby reducing the friction force when the first drive unit or the second drive unit pushes the actuator 1310 to move.

[0091] The material arm 13 is provided with a limit block 1304 , and the ejecting rod 1306 is constructed with a limit cavity 1306 b , and the limit block 1304 is at least partially located in the limit cavity 1306 b for limiting the extreme position of the movement of the ejecting rod 1306 .

[0092] Preferably, the second end of ejector rod 1306 is connected to the third end of linkage block 1307, and the fourth end of linkage block 1307 is arranged opposite the third end. The fourth end of linkage block 1307 is connected to actuator 1310. Preferably, limiting cavity 1306b is connected to the third end of linkage block 1307. When ejector rod 1306 approaches the accommodating portion 200 to the limit position, one end of limiting block 1304 abuts the third end of linkage block 1307. When ejector rod 1306 moves away from the accommodating portion 200 to the limit position, the other end of limiting block 1304 abuts the inner wall of limiting cavity 1306b. Preferably, limiting block 1304 is located within the inner cavity of main body 1305.

[0093] This embodiment also provides a method for using the material arm 13 as described above, characterized in that the second end of the ejector rod 1306 is used to drive the ejector rod 1306 to move so that the ejector rod 1306 and the receiving portion 200 are moved closer to or farther away from each other;

[0094] The ejector rod 1306 and the receiving portion 200 are spaced apart from each other to allow the material to enter or exit the receiving portion 200;

[0095] The ejector rod 1306 and the accommodating portion 200 are brought close to each other to press the material contained in the accommodating portion 200 tightly.

[0096] The method of this embodiment drives the ejection rod 1306 to move by the second end of the ejection rod 1306 so that the ejection rod 1306 and the accommodating portion 200 are closer to or farther away from each other. Therefore, if there are cylinders, conduits and other driving components and components such as sensors for driving the ejection rod 1306, the cylinders, conduits and other driving components and components such as sensors for driving the ejection rod 1306 are all arranged at the second end of the ejection rod 1306, and the second end of the ejection rod 1306 is away from the harsh high-temperature environment, so that the service life of these components is extended, which well solves the technical problem in the prior art that cylinders, air pipes, sensors and other components that are not adapted to the harsh high-temperature environment are frequently damaged due to the harsh high-temperature environment, thereby resulting in high production costs.

[0097] The method of driving the ejecting rod 1306 to move away from the receiving portion 200 by the second end of the ejecting rod 1306 includes: moving the actuator 1310 to move the linkage block 1307 in a direction away from the receiving portion 200, the linkage block 1307 being connected to the second end of the ejecting rod 1306. The method of driving the ejecting rod 1306 to move toward the receiving portion 200 by the second end of the ejecting rod 1306 includes: releasing the actuator 1310 to move the linkage block 1307 in a direction toward the receiving portion 200, the linkage block 1307 being connected to the second end of the ejecting rod 1306. This step facilitates the movement of the ejecting rod 1306 by driving the ejecting rod 1306 by the actuator 1310 located outside the inner cavity of the main body 1305.

[0098] This embodiment provides a conveying device, which includes the material arm 13 as described above.

[0099] The conveying device further comprises a first driving unit and a second driving unit, wherein the first driving unit comprises a telescopic component 7 and a first stopper 8, and the second driving unit comprises a second stopper 9. The material arm 13 is movable along a first direction and has a first position and a second position along the first direction. The first position is as follows: Figure 6 、 Figure 7 、 Figure 8 and Figure 10 As shown, the second position is Figure 9 As shown, the material arm 13 is used to move to the first position to perform the material feeding and picking operation step or the material recovery and release operation step, and the material arm 13 is used to move to the second position to perform the material feeding and release operation step or the material recovery and picking operation step. The first drive unit is used to drive the actuator 1310 of the material arm 13 in the first position to move; the second drive unit is used to drive the actuator 1310 in the second position to move. The first and second drive units drive the actuator 1310 at corresponding positions to perform corresponding actions, thereby achieving the conveyance of materials such as bar stock 15 and the recovery of materials if they are not delivered to the designated position.

[0100] The conveying device also includes a mounting plate 6. A first stopper 8 of a first drive unit is used to drive the actuator 1310 of the material arm 13 in the first position to move. One end of a telescopic member 7 is pivotally connected to the mounting plate 6, and the other end of the telescopic member 7 is pivotally connected to the first stopper 8. The first stopper 8 is pivotally connected to the mounting plate 6. The location on the mounting plate 6 where the telescopic member 7 is pivoted and the location on the mounting plate 6 where the first stopper 8 is pivotally connected are two different locations. The location on the first stopper 8 where the telescopic member 7 is pivoted and the location on the mounting plate 6 where the first stopper 8 is pivotally connected are two different locations. The telescopic member 7 is preferably a pneumatic cylinder, or alternatively, an electric push rod, as long as it can achieve telescopic length. The change in the length of the telescopic member 7 drives the location on the first stopper 8 where the telescopic member 7 is pivoted to rotate about the location on the first stopper 8 where the telescopic member 7 is pivoted to the mounting plate 6, thereby driving the first stopper 8 into or out of contact with the actuator 1310 of the material arm 13. Preferably, the first stopper 8 engages or disengages with the cam bearing 1311 on the actuator 1310.

[0101] The second drive unit includes a second stopper 9, which is fixedly connected to the mounting plate 6. The second stopper 9 contacts the actuator 1310 of the material arm 13 in the second position to drive the actuator 1310 in the second position to move. Specifically, when the material arm 13 moves to the second position, the second stopper 9 contacts the actuator 1310, and the material arm 13 continues to move in a direction away from the first stopper 8. Because the actuator 1310 is blocked by the second stopper 9, the actuator 1310 moves relative to the main body 1305 and the accommodating portion 200 on the main body 1305.

[0102] like Figure 10 As shown, the conveying device further includes a guide rail 10, a slider 11, and a third drive mechanism. The guide rail 10 is fixedly connected to the mounting plate 6 and extends along the first direction. The slider 11 is disposed on the guide rail 10 and moves along the guide rail 10. The third drive mechanism and the mounting plate 6 are located on either side of the feed arm 13. The third drive mechanism includes a traction belt 4 and a traction belt clamp 12, which is connected to the traction belt 4. The feed arm 13 has a connecting portion 1301 fixedly connected to the traction belt clamp 12, which is fixedly connected to the slider 11. The guide rail 10 guides the movement of the feed arm 13, and the third drive mechanism drives the movement of the feed arm 13. The third drive mechanism also includes a motor 2, a driving pulley, and a driven pulley. The traction belt 4 is wound around the driving pulley and the driven pulley. The motor 2 is connected to the driving pulley, driving the driving pulley to rotate, thereby driving the traction belt 4. In this embodiment, the traction belt 4 is preferably a synchronous belt.

[0103] like Figure 10As shown, the conveying device also includes a back plate 500, a top plate 600, and a discharge plate 1; the back plate 500 is used to mount a third drive member, and the top plate 600 is connected to the back plate 500 to form a protective cavity, with the traction belt 4 disposed within the protective cavity; the material is a bar 15 for forging, and the discharge plate 1 is connected to the top plate 600. The discharge plate 1 is configured with a discharge port, from which the bar 15 extending from the discharge port enters the accommodating portion 200 of the material arm 13; a shearing tool 14 is provided on the discharge plate 1, and is used to cut the bar 15 extending from the discharge port. This structure isolates and protects the driving traction belt 4, preventing the high temperature of the bar 15 from damaging the traction belt. The provision of the shearing tool 14 facilitates cutting the bar 15.

[0104] The material arm 13 can move along a first direction, and the first direction and the moving direction of the ejector rod 1306 are both the length direction of the ejector rod 1306. The first direction is perpendicular to the opening direction of the mold. Figures 6-10 As shown, the mold comprises an upper and lower mold, with the lower mold 16 shown. The mold opens in the vertical direction. This structure can reduce the mold opening distance, shorten the mold opening and closing time, and improve production efficiency. Moreover, the mold opening distance is not affected by the length of the ejector pin 1306. Even if the ejector pin 1306 is longer to avoid high-temperature and harsh environments, the mold opening distance does not change when the material arm 13 is extended into the mold, and the increase in the length of the ejector pin 1306 does not affect production efficiency.

[0105] This embodiment provides a method for using the output device, the method comprising:

[0106] Operation steps for material feeding;

[0107] If the material feeding operation steps are unqualified, the material recovery operation steps are executed.

[0108] The operation steps of the method can not only realize the feeding of materials such as rods 15, but also can recover materials such as rods 15 when the operation steps of feeding the materials are unqualified.

[0109] The material feeding operation steps include material feeding picking, material feeding conveying and material feeding releasing;

[0110] The material feeding and picking up includes:

[0111] The telescopic component 7 drives the first stopper 8 to drive the actuator 1310 of the material arm 13 at the first position to move in a direction away from the accommodating portion so that the ejecting rod 1306 is away from the accommodating portion 200; specifically, the ejecting rod 1306 can move to abut against the limit block 1304;

[0112] The bar 15 extends from the discharge port of the discharge plate 1 and enters the receiving portion 200;

[0113] After the bar 15 enters the preset position of the accommodating portion 200, the telescopic component 7 drives the first stopper 8 to disengage the actuator 1310 of the material arm 13 at the first position, so that the ejector rod 1306, under the action of the elastic member 1308, presses against the bar accommodated in the accommodating portion 200;

[0114] The shearing tool 14 provided on the discharge plate 1 cuts the bar 15;

[0115] The material feeding and conveying comprises:

[0116] After the bar 15 is cut, the third drive mechanism drives the feed arm 13 to move from the first position to the second position along the first direction. Specifically, the bar 15 is now located above the groove of the lower die 16 of the mold. Normally, the bar 15 is released to allow it to fall into the groove. Specifically, this can be achieved by rotating the traction belt 4 counterclockwise.

[0117] The material feeding and releasing comprises:

[0118] After the feed arm 13 reaches the second position, the third drive mechanism continues to drive the feed arm 13 in the direction from the first position toward the second position to release the bar 15. Specifically, the actuator 1310 is blocked by the second stopper 9. The actuator 1310, the linkage block 1307, and the ejector rod 1306 remain stationary. The elastic member 1308 is compressed, and the accommodating portion 200 continues to move under the drive of the third drive mechanism, causing the actuator 1310, the linkage block 1307, and the ejector rod 1306 to move relative to the accommodating portion 200, thereby releasing the bar 15. Preferably, the ejector rod 1306 can be moved until it abuts against the stopper 1304 to release the bar 15.

[0119] If the bar material 15 is not accurately fed into the groove of the lower die 16 of the mold, the material feeding operation step is unqualified. At this time, the material recovery operation step is performed.

[0120] The operational steps of material recovery include material recovery pickup, material recovery transportation and material recovery release;

[0121] The material recycling and collection includes:

[0122] The third driving mechanism drives the feed arm 13 to move along the first direction from the second position to the first position. The gap between the working surface of the feed arm 13 and the working surface of the target mold after the mold is opened allows the bar 15 that has not entered the groove of the target mold to be pressed tightly against the accommodating portion 200 by the ejector rod 1306 during the movement of the feed arm 13 from the second position to the first position. Specifically, the traction belt 4 can rotate clockwise.

[0123] Material recovery and transportation:

[0124] After the bar material 15 that has not entered the groove of the target mold is pressed against the accommodating portion 200 by the ejector rod 1306, the third driving mechanism drives the material arm 13 to continue moving in the first direction until it moves to the first position;

[0125] Material recovery release:

[0126] After the material arm 13 moves to the first position, the telescopic member 7 drives the first stopper 8 to cause the actuator 1310 of the material arm 13 in the first position to move away from the accommodating portion 200, so that the ejector pin 1306 moves away from the accommodating portion 200, thereby releasing the bar 15 that has not entered the groove of the target mold and is pressed against the accommodating portion 200 by the ejector pin 1306. Specifically, after being released, the bar 15 falls into the recovery device.

[0127] Among them, the working surface of the material arm 13 is the surface on the side where the opening of the accommodating portion 200 is located, and the working surface of the target mold is the surface on the side of the target mold that accommodates the bar material 15. Specifically, in this embodiment, the working surface of the material arm 13 is the lower surface surrounding the accommodating portion 200, the target mold is the lower mold 16, and the tool surface of the lower mold 16 is the surface on the side where the groove of the lower mold 16 is located, that is, the upper surface of the lower mold 16.

[0128] When the bar 15 falls into the groove of the lower mold 16, the gap between the working surface of the material arm 13 and the working surface of the target mold after the mold is opened allows the working surface of the material arm 13 to slide over the bar 15 without allowing the bar 15 to enter the accommodating portion 200 again.

[0129] The conveying device of this embodiment makes the pick-up and placement cycle fixed, ensures the consistency of product quality, and avoids the problem of non-fixed pick-up and placement time during manual loading.

[0130] The conveying device of this embodiment enables automatic loading and unloading of heated bars 15, improving the employee work environment, increasing efficiency, and ensuring consistent product quality. Furthermore, the use of an extendable arm 13, isolated from the synchronous belt, motor, and other components, effectively protects the lifespan of components. Automatic removal of misaligned bars 15 prevents damage to molds and equipment. This conveying device effectively addresses the problems of poor forging working environment, low efficiency, and high costs.

In particular, the various technical features described in the various embodiments may be combined in any manner, provided there are no logical or structural conflicts.
