Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy forging, in particular to an aluminum alloy forging buffer mechanism. Background Art

[0002] Aluminum alloy forging is a method of metal material processing, which mainly changes the shape and structure of the aluminum alloy billet in the mold by applying pressure to it.

[0003] In the process of forging aluminum alloy billets, existing aluminum alloy manufacturers generally install the mold on the base by means of mounting or clamping in order to more flexibly respond to different needs of customers, so as to facilitate mold replacement in response to customer needs. In order to pursue higher economic benefits, some aluminum alloy manufacturers adopt high-speed hammer forging to improve the efficiency of forging. However, under the high-frequency and high-intensity impact of the hammer head of the forging machine, the mold itself will vibrate to a certain extent, resulting in mutual extrusion between the mold and the base. This mutual extrusion between the mold and the base will directly affect the installation stability between the mold and the base after a certain frequency, thereby affecting the forging accuracy of the product. At the same time, this mutual extrusion between the mold and the base will also reduce the service life of the mold itself.

[0004] Therefore, in order to improve the service life of the die and ensure the quality of the workpiece, an aluminum alloy forging buffer mechanism is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an aluminum alloy forging buffer mechanism to solve the problem that the mold vibrates under the long-term and high-intensity impact of the hammer head of the forging machine, affecting the forging accuracy of the product and the service life of the mold. Through the support ring, buffer assembly, transmission assembly and sand loosening assembly, the support ring and buffer assembly can play a buffering role for the forging mold when it vibrates, reduce the negative impact of the vibration, and improve the stability of the mold.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an aluminum alloy forging buffer mechanism, used in conjunction with a forging die, includes a base, a storage box, a limit block and a support ring, and also includes a buffer assembly, a transmission assembly and a sand loosening assembly, the storage box is located at a top position near the center of the base, the support ring is located above the storage box and the storage box is movably connected, the limit block is located at a top position near the edge of the base, the buffer assembly is located between the support ring and the limit block, the forging die is installed on the inner side of the support ring, the interior of the storage box is filled with sand and gravel particles, and the bottom of the forging die is inserted into the sand and gravel particles, the buffer assembly drives the sand loosening assembly through the transmission assembly, the forging die will be buffered by the buffer assembly and the sand and gravel particles in the storage box after being pressurized, and the forging die will return to its position through the buffer assembly after the pressure ends and drive the sand loosening assembly to loosen the sand and gravel particles in the storage box through the transmission assembly.

[0007] It can be seen that when the forging die is cushioned, sand and gravel particles are filled at its bottom. While ensuring the forging effect, it can also play an effective shock-absorbing role. However, in actual use, compared with this scheme, the existing scheme has a problem that the sand and gravel particles filled at the bottom of the forging die will be reduced due to the long-term and high-frequency forging hammer of the forging die, and the internal gaps of the sand and gravel particles will gradually become compacted and solidified, which will directly affect the shock-absorbing effect of the sand and gravel particles and affect the stability of the forging die.

[0008] Preferably, the buffer assembly includes a top support rod, a limiting cylinder, a connecting copper tube, a bottom support rod, a sliding block, a circulation hole, a circulation hole, an extrusion block and a buffer spring, a connecting ring is installed on the buffer assembly, and the buffer assembly is connected to a connecting rope through the connecting ring, the sliding block is slidably connected to the inner side of the limiting block, the bottom support rod is hinged to the top of the sliding block, the limiting cylinder is fixedly installed to the top of the bottom support rod, the circulation hole is opened at both ends of the outer surface of the limiting cylinder near the top and the bottom, the connecting copper tube is connected to the circulation hole, the connecting copper tube is fixedly connected to the outer surface of the limiting cylinder, a connecting piece is installed above the top support rod, the bottom of the top support rod is fixedly connected to the extrusion block, buffer springs are installed on the upper and lower sides of the extrusion block, and the buffer spring is located on the inner side of the limiting cylinder, and the interior of the limiting cylinder and the connecting copper tube is filled with liquid Pressurized oil, the hydraulic oil in the limit cylinder will flow to the top of the extrusion block through the connecting copper tube after being pressurized, and the sliding block will also squeeze the adjusting spring for buffering after being pressurized, the movable range of the extrusion block is located between the upper and lower flow holes, columnar protrusions are provided at both ends of the sliding block, and the sliding block is sleeved with the adjusting spring through the columnar protrusions at both ends, an adjusting spring is provided inside the limit block, the adjusting spring is installed on the inner side of the limit block near the two ends of the sliding block, the buffer assembly and the limit block are evenly distributed on the outside of the support ring, the connecting ring is fixedly installed at the bottom of the top support rod, and the connecting ring is only installed on the base near the quarter point, the bottom of the connecting ring is connected to the connecting rope, and a sliding wheel is installed on the outer surface of the storage box near the bottom of the connecting ring, and the connecting rope is connected to the inner side of the pulling wheel through the sliding wheel.

[0009] In the above scheme, when the forging die vibrates and is subjected to pressure due to impact, the pressure will be transmitted to the support ring, and then the top support rod in the buffer assembly in the corresponding position will be squeezed through the support ring, so that the top support rod squeezes the extrusion block, and the extrusion block squeezes the buffer spring and the hydraulic oil in the limit cylinder, so that the buffer spring is deformed. At the same time, the sliding block will also be displaced in the limit block, squeezing the adjustment spring in the limit block for buffering. In this process, the hydraulic oil will flow through the bottom of the extrusion block to the connecting copper tube, and then flow to the top of the extrusion block through the connecting copper tube. In this process, the hydraulic oil can dissipate the heat generated by the deformation of the buffer spring in the connecting copper tube.

[0010] It can be seen that there are many common buffer components. Combined with the current usage scenarios, considering the high pressure and high frequency in the forging process, the buffer spring will generate a certain amount of heat during use. Therefore, the heat in the buffer spring needs to be processed to avoid the buffer spring from overheating after a period of use, which will reduce the service life of the buffer spring.

[0011] Preferably, a pressure rod is fixedly connected to the bottom of the support ring, a connecting rod is fixedly installed on the outer surface of the storage box near the pressure rod, a limiting cylinder is fixedly installed at a section of the connecting rod away from the storage box, a return spring is sleeved on the inner side of the limiting cylinder near the bottom of the pressure rod, and the bottom of the pressure rod is fitted with the top of the return spring, and a pressure sensor is fixedly installed on the inner side of the limiting cylinder near the center of the support ring.

[0012] It can be seen that there are many kinds of commonly used support rings. Combined with the current usage scenarios, buffer components and adjustment springs are mainly used for buffering. However, during long-term use, the components in the buffer component and the adjustment spring may be accidentally affected, resulting in abnormal weakening of the rebound ability of the components and the adjustment spring in the buffer component on one side, causing the overall imbalance of the equipment, which directly affects the forging effect of the product. The support ring can rebound normally after being compressed by matching the pressure rod, the pressure sensor and the adjustment spring. Once the rebound ability of the components and the adjustment spring in the buffer component on one side is abnormally weakened, the pressure rod will be skewed during operation, and the pressure rod will squeeze the pressure sensor. The pressure rod itself is in the shape of a vertical rod. Under the restriction of the restriction tube, the further tilt of the support ring can also be suppressed. At the same time, after the pressure sensor detects abnormal force, it can upload the corresponding position information of the abnormal force point for notification, so as to facilitate maintenance as soon as possible, which is beneficial to improve the stability of equipment operation, and effectively improve the timeliness of abnormal situation processing, and reduce the economic losses caused by abnormal situations.

[0013] Preferably, the transmission assembly includes a pulling wheel, a connecting block, a return torsion spring, a transmission block, a clamping claw and a first pulley, the connecting block is located at the bottom of the pulling wheel, and the connecting block is connected to the pulling wheel by a bearing, the transmission block and the pulling wheel are fixedly installed, and the clamping claw is installed on the outer surface of the transmission block near the top, the clamping claw and the connecting block are connected by a bearing and a torsion spring, and the clamping claw fits with the surface of the transmission block, the connecting block and the first pulley are fixedly installed, the upper and lower ends of the return torsion spring are respectively installed with the connecting block and the transmission block, and the ratio of the diameter of the through hole opened at the top of the connecting block for connecting the transmission block and the pulling wheel to the diameter of the connection between the transmission block and the pulling wheel is three to two, and the clamping claw makes the clamping claw fit with the surface of the transmission block through the torsion spring at the connection with the connecting block, the clamping claw cannot drive the transmission block when it rotates clockwise, and can drive the transmission block when it rotates counterclockwise.

[0014] In the above scheme, the return torsion spring on the transmission component can accumulate the force transmitted by the pulling wheel to drive the transmission block to rotate, and is used to drive the transmission block to rotate in the opposite direction after the forging die stops vibrating, and also drives the connecting rope to return, and drives the first pulley after the forging hammer head is lifted, and cooperates with the sand loosening component to loosen the sand and gravel particles at the bottom of the forging die. In this process, the buffer component and the support ring will push the forging die back, and the horizontal height of the sand and gravel particles squeezed to the edge of the forging die is higher than the sand and gravel particles at the bottom of the forging die after being compressed. The sand and gravel particles squeezed to the edge of the forging die will flow back, and loosening the sand through the sand loosening component can make the sand and gravel particles effectively cope with the next forging.

[0015] It can be seen that loosening the sand and gravel particles at the bottom of the forging die at a time point staggered from the time when the forging die is pressed can improve the sand loosening effect to a certain extent, and also improve the smoothness of the sand loosening component during use, increase the looseness of the sand and gravel particles, and improve the shock absorbing effect of the forging die.

[0016] Preferably, the sand loosening assembly includes a clamping block, a main shaft rod, a supporting spring, a sand loosening roller and a clamping block. A transmission belt is sleeved on the outer side of the transmission assembly near the bottom. The transmission assembly can drive the sand loosening assembly through the transmission belt. The inner side of the transmission belt is connected to a second pulley at one end away from the first pulley. The second pulley air collecting bottom assembly is located in a reserved hole opened at the bottom of the storage box to prevent sand and gravel particles from invading and affecting the normal operation of the sand loosening assembly. The clamping block is movably clamped with the middle part of the second pulley, and the clamping block The middle part is fixedly installed with the main shaft rod, the outer surface of the main shaft rod is fixedly installed with the sand loosening roller near the top, the clamping block is fixedly installed at the bottom of the main shaft rod, the supporting spring is movably sleeved on the bottom of the clamping block, and the clamping block and the supporting spring are both located on the bottom inner side of the storage box, the sand loosening roller is located at the bottom of the forging die, and the four sand loosening rollers do not interfere with each other, the trajectory of the sand loosening roller when rotating is the inscribed circle of the cross-sectional circle of the bottom of the forging die, and the central axis of the main shaft rod is located at the midpoint of the radius of the cross-sectional circle of the bottom of the forging die.

[0017] In the above scheme, the clamping block in the sand loosening assembly can be used to clamp onto the second pulley, so that the second pulley can drive the main shaft rod to rotate, and drive the sand loosening roller to rotate to loosen the sand and gravel particles. At the same time, when the forging die is under pressure, the sand loosening assembly does not rotate, and the clamping block will move downward in the middle of the second pulley and squeeze the supporting spring. After the forging die is compressed, the second pulley drives the clamping block to rotate through indirect transmission, drives the sand loosening roller to rotate, and at the same time the supporting spring pushes the clamping block upward, so that the sand loosening roller can loosen the sand more comprehensively.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. Compared with the existing aluminum alloy forging buffer mechanism, the aluminum alloy forging buffer mechanism is more effective in dealing with the forging die under the impact of the forging hammer for a long time and at a high intensity, and the forging die will vibrate during the forging process, affecting the stability of the workpiece production. Therefore, the support ring and its internal return spring and pressure sensor are used to limit the position of the forging die, and the buffer component and the sand and gravel in the storage box are used to buffer the vibration of the forging die during the forging process. The buffer component is mainly used to effectively deal with the high-frequency and high-intensity impact of the forging hammer on the die, and is used to further improve the stability of the forging die when in use. The top support rod and extrusion block in the buffer component will push the hydraulic oil at the bottom of the extrusion block. Extruded downward, it enters the top of the extrusion block through the connecting copper tube. At the end of forging, the buffer spring will drive the extrusion block back to its position, and the hydraulic oil above the extrusion block will return to the bottom of the extrusion block through the connecting copper tube. The buffer spring will deform multiple times in response to high-intensity and high-frequency forging, and will generate a certain amount of heat in the process of deformation. In this transportation process, the hydraulic oil can play a certain buffering role, and the hydraulic oil will carry the heat generated by the deformation of the buffer spring into the connecting copper tube. The shape of the connecting copper tube facilitates heat dissipation during the transportation of the hydraulic oil, avoiding the situation where the heat of the buffer spring cannot be dissipated during the long-term high-intensity and high-frequency compression process, resulting in a reduction in the service life of the buffer spring.

[0020] 2. The aluminum alloy forging buffer mechanism is provided with a sand loosening component, which is matched with a connecting rope and a transmission component, so that the forging die squeezes the sand and gravel particles downward after being impacted, and presses down the support ring to compress the buffer component and pull the connecting rope, which is converted into driving the sand loosening component to rotate through the transmission component, so that the sand loosening roller in the sand loosening component breaks up the sand and gravel particles at the bottom of the forging die, thereby loosening the sand, so as to avoid the sand and gravel particles at the bottom of the forging die from becoming hardened when the forging die is subjected to high-intensity impact for a long time, affecting the buffering effect of the forging die, and helping to further improve the service life of the forging die when in use.

[0021] 3. The aluminum alloy forging buffer mechanism adopts a transmission assembly, through the return torsion spring, transmission block and clamping claw and other components in the transmission assembly, when the connecting rope pulls the pulling wheel, it will not immediately drive the clamping claw and the first pulley and other components to rotate through the transmission block, but the rotation force is stored through the return torsion spring. When the forging hammer head is lifted, the compressed sand and gravel particles at the bottom of the forging die are loosened to ensure the buffering effect of the sand and gravel particles in the storage box, and avoid the sand loosening roller to loosen the sand and gravel particles at the bottom of the forging die when the forging die is under pressure, which is conducive to improving the sand loosening effect.

The connecting rope 11 is connected to the inner side of the pulling wheel 81 through the sliding wheel 10. The clamping claw 85 is connected to the surface of the transmission block 84 through the torsion spring at the connection with the connecting block 82.

[0038] During the working process of the present invention, after the forging die 7 is installed on the inner side of the support ring 4, when the forging die 7 is impacted by the forging hammer, the sand and gravel in the storage box 2 are first used to perform preliminary buffering on the forging die 7, and at the same time, the buffer assembly 6 is squeezed by pressing down the support ring 4, and further buffering is performed by the buffer spring 68 in the buffer assembly 6 and the hydraulic oil filled in the limit cylinder 62, thereby improving the stability of the forging die 7;
