Description

Technical Field

[0001] The present invention relates to the technical field of mechanical adjustment equipment, in particular to an automatic clamping force adjustment device for a light alloy casting machine. Background Art

[0002] In the field of squeeze casting, the precise control of the clamping force plays a key role in product quality and production efficiency. Squeeze casting machines are usually used in the casting of non-ferrous metals such as aerospace, automotive, and high-speed rail, including light alloys. There are many problems to be solved in the clamping force adjustment of traditional light alloy casting machines. In the hydraulic oil treatment link, the hydraulic system, as the core part providing power for the light alloy casting machine, its working stability directly affects the accuracy of the clamping force. However, in the prior art, impurities are easily mixed into the hydraulic oil during the recycling process, such as metal chips generated during the casting process, dust in the processing environment, etc. After these impurities enter the hydraulic system, they will aggravate the wear of each moving part in the system, reduce the service life of the equipment, and may also cause oil circuit blockage, hinder the transmission of hydraulic oil, and then cause fluctuations in the clamping force, affecting the dimensional accuracy and surface quality of the castings. Moreover, air bubbles are easily mixed into the hydraulic oil during the flow process. The existence of air bubbles will reduce the transmission efficiency of the hydraulic oil, cause the system to respond slowly, and cannot meet the requirements of high-precision squeeze casting technology for rapid and precise adjustment of the clamping force.

[0003] Chinese Patent with Publication No. CN102259180A discloses an automatic clamping force adjustment device for a die-casting machine, including guide columns and die-set adjusting nuts arranged thereon. A clamping force sensor is installed on the guide column, and a wire lead-out end is arranged on the clamping force sensor to connect to a power supply and transmit signals; a boss is arranged on the outer edge of the die-set adjusting nut, and concave holes or grooves are evenly distributed on the boss. The die-set adjusting nut is installed with an induction reading head that can sense the concave holes or grooves through a support, and a wire lead-out end is arranged on the induction reading head to connect to a power supply and transmit signals. The die-set adjusting nut can drive the guide column to rotate in a threaded manner through the die-set adjustment system of the die-casting machine. The clamping force range value of the die-casting machine is 70% - 130% of the nominal value of the die-casting machine's clamping force. In the production process of the die-casting machine, the size of the clamping force of the die-casting machine is monitored by the clamping force sensor on the guide column and immediately fed back to the die-casting machine for comparison with the clamping force set value. If the clamping force exceeds the set range, the die-set adjustment system of the die-casting machine will be automatically activated to drive the die-set adjusting nut to rotate and adjust the clamping force. This process does not require the operation of staff, which is safe and fast.

[0004] However, there are still some problems with this patent: The flash of the objects produced by the casting machine is processed manually. This method is not only inefficient and consumes a large amount of labor costs, but also the trimming effect depends on the experience and operation level of the workers, making it difficult to ensure consistency. When there is a lot of flash, the manual processing speed is difficult to keep up with the production rhythm, affecting the overall production efficiency; if the flash is not processed in time, it may also damage the equipment in subsequent processes. Moreover, this device cannot be automatically adjusted, and the trimming work and the clamping force adjustment are independent of each other, failing to form an organic linkage. The power generated during the trimming process cannot be effectively utilized, resulting in energy waste. At the same time, when facing the production requirements of different castings, it is difficult to adjust the clamping force in real time according to the actual situation, and it cannot meet the diverse and personalized market demands.

Detailed implementation manners

[0033] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0034] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] Second, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0036] Embodiment 1

[0037] Referring to Figures 1 - 6 , this is the first embodiment of the present invention, and this embodiment provides an automatic clamping force adjusting device for a light alloy casting machine.

[0038] Specifically, an automatic clamping force adjusting device for a light alloy casting machine includes a casting machine and a bearing base, and further includes a filtering mechanism 100 and a transmission adjusting mechanism 200.

[0039] The filtering mechanism 100 is firmly fixed on the bearing base through a mounting frame 101, providing a solid support for the bearing cylinder 103. The bearing cylinder 103 is fixedly installed on the mounting frame 101. One outer wall of the bearing cylinder 103 is communicated with a liquid inlet 104, and one end is communicated with a liquid outlet 105. The hydraulic oil flowing in from the liquid inlet 104 will first pass through the filtering component 102 in the bearing cylinder 103 for treatment. The filtering component 102 is composed of a filtering element and a degassing element.

[0040] The filtering element is installed inside the bearing cylinder 103. The mounting cover 1021 is detachably installed on one side of the bearing cylinder 103, which is convenient for later maintenance and replacement. Along the axis on the mounting cover 1021, a plurality of filter pipes two 1024 with internal cavities are evenly distributed. The inner wall of the filter pipe two 1024 is fixed with a filter pipe one 1023 whose length is greater than itself, and the filter pipe one 1023 corresponds to the filter pipe two 1024. An installation plate 1022 is sleeved on the outer walls of the plurality of filter pipes one 1023, and a through hole one communicated with the filter pipe one 1023 is opened on the installation plate 1022. At the junction of the filter pipe two 1024 and the filter pipe one 1023, a filter plate 1025 connecting the two is provided. The filter plate 1025 has a plurality of through holes two for the hydraulic oil to pass through, and a filter screen is provided in each through hole two. During operation, after the hydraulic oil enters from the liquid inlet 104, it first flows into the filter pipe two 1024, and is preliminarily filtered through the filter screen and the through holes two on the filter plate 1025, and large particle impurities are intercepted, and then it flows into the filter pipe one 1023. On the inner wall of the bearing cylinder 103 near the liquid outlet 105, a plurality of layers of sieve plates 106 are fixedly provided, which further finely filters the preliminarily filtered hydraulic oil during operation to ensure high purity.

[0041] The degassing component is located at the bottom of the bearing cylinder 103 and is fixedly installed on the mounting frame 101. The degassing component includes a liquid-changing cylinder 107, on which a plurality of degassing parts 108 are provided. The liquid-changing cylinder 107 communicates with the bearing cylinder 103. The degassing parts 108 suck out the hydraulic oil in the liquid-changing cylinder 107. During this process, the gas in the hydraulic oil is screened out, and then the hydraulic oil with the gas discharged is reinjected into the liquid-changing cylinder 107. Finally, the hydraulic oil entering from the liquid inlet 104 undergoes double filtration and the internal bubbles are removed, and then flows out through the liquid outlet 105, providing high-quality hydraulic oil for the subsequent system. One end of the liquid outlet 105 is connected with a flow control component 109, and the flow control component 109 realizes the control of the output volume of the hydraulic oil. According to the actual requirements, by adjusting its own structure, the flow area of the hydraulic oil outlet is changed, so as to accurately control the output volume.

[0042] The transmission adjustment mechanism 200 includes a cutting tool assembly and a transmission assembly, both of which are installed on the bearing base. The cutting tool assembly is located on one side of the filtering mechanism 100. When the object produced by the casting machine has burrs, the burrs come into contact with the cutting tool assembly. As the number of burrs increases, the force received by the cutting tool assembly increases, and the force is transmitted to the transmission assembly. The transmission assembly is located on one side of the filtering mechanism 100 and is linked with the cutting tool assembly.

[0043] In summary, the die clamping force automatic adjustment device of the light alloy casting machine relies on the coordinated operation of the filtering mechanism 100 and the transmission adjustment mechanism 200. In the filtering mechanism 100, the mounting frame 101 is firmly fixed on the bearing base to support the bearing cylinder 103. The hydraulic oil flowing in from the liquid inlet 104 first undergoes double filtration through the combination of the mounting cover 1021, the first filter pipe 1023, the second filter pipe 1024, the filter plate 1025 and the multi-layer sieve plate 106 in the filter element to remove impurities; then the air bubbles are discharged through the liquid-changing cylinder 107 and the degassing parts 108 in the degassing component, and high-quality hydraulic oil is output through the liquid outlet 105. In the transmission adjustment mechanism 200, the cutting tool 2022 of the cutting tool assembly is installed at one end of the sliding column 2021. By overcoming the elastic force of the first spring 2024 with the acting force of the burrs, it moves horizontally in the fixed box 201 to trim the burrs; the transmission assembly then converts the linear power of the sliding column 2021 in the cutting tool assembly into rotational power through complex structures such as the limiting body 205, the conversion part, and the transmission part 204, drives the pulley two 2042 to rotate, and finally realizes the automatic collaborative work of the device, meets the requirement of automatically adjusting the die clamping force during the squeeze casting process, and improves the stability of the casting process and the product quality.

[0044] Embodiment 2

[0045] Refer to Figures 1 - 8 , which is the second embodiment of the present invention, and this embodiment is implemented based on the previous embodiment.

[0046] Specifically, the flow control component 109 is rotatably arranged at the output end of the liquid outlet 105 through the first pulley 1091. This mechanical installation method ensures its flexible rotation and reception of external power. The other end of the first pulley 1091 is connected to the flow control member, and an adjusting rod 1092 is fixedly arranged on the first pulley 1091. The working principle is that when the external power drives the first pulley 1091 to rotate, the adjusting rod 1092 rotates accordingly, thereby driving the flow control member to act.

[0047] The flow control member includes a first mounting ring 1093 fixedly arranged at the other end of the first pulley 1091. The first mounting ring 1093 provides the basic support and connection points for the entire flow control member. A rotating ring 1095 is rotatably arranged on the first mounting ring 1093. The rotating ring 1095 can rotate flexibly around the first mounting ring 1093 to achieve angle adjustment. A plurality of flow limiting vanes 1096 are evenly rotatably arranged along the axis on the rotating ring 1095, and a positioning post 1097 is arranged on each flow limiting vane 1096. The flow control member further includes a second mounting ring 1094 and a fixed pin 1098. One end of the fixed pin 1098 is connected to the first mounting ring 1093 and penetrates through the rotating ring 1095. The second mounting ring 1094 is fixedly connected to the first mounting ring 1093 through the fixed pin 1098. A plurality of sliding grooves are evenly opened along the axis on the second mounting ring 1094. The sliding grooves correspond to the positioning posts 1097 one by one, and the positioning posts 1097 are slidably connected to the second mounting ring 1094 through the sliding grooves. During operation, the adjusting rod 1092 drives the rotating ring 1095 to rotate. During the rotation of the rotating ring 1095, the flow limiting vanes 1096 change their angles accordingly, and the positioning posts 1097 slide in the sliding grooves of the second mounting ring 1094, thereby adjusting the size of the hydraulic oil outlet surrounded by the plurality of flow limiting vanes 1096, so as to accurately control the output volume of the hydraulic oil and meet the requirements for the hydraulic oil flow rate under different working conditions.

[0048] The cutter assembly includes a fixed box 201 and a cutter member 202. The fixed box 201 is arranged on the bearing base and has a cavity inside, providing space for the sliding of the cutter member 202. The cutter member 202 includes a sliding column 2021 slidably arranged on the side wall of the fixed box 201, and the sliding column 2021 can slide smoothly on the side wall of the fixed box 201. One end of the sliding column 2021 is fixedly provided with a cutter 2022 for trimming the burr, and the outer wall of the other end is fixedly provided with a limiting ring 2023. A first spring 2024 is sleeved on the outer wall of the sliding column 2021 on one side of the limiting ring 2023. The working principle is that when the object produced by the casting machine has burrs, the burrs contact the cutter 2022 and exert a force. As the number of burrs increases, the force increases, overcoming the elastic force of the first spring 2024, pushing the cutter 2022 and the sliding column 2021 to move horizontally in the fixed box 201, realizing the trimming of the burrs. The first spring 2024 plays a buffering and resetting role in this process, ensuring that the cutter 2022 can return to the initial position when there is no burr force, and at the same time can also adaptively adjust the position of the cutter 2022 according to the burr thickness and the magnitude of the force, ensuring the trimming effect.

[0049] The sliding column 2021 passes through the fixed box 201 and is connected to the limiting body 205. The limiting body 205 is in a U shape, and Z-shaped sliding grooves 2054 are provided on both sides thereof. A slider 2052 is slidably provided on the inner wall of the sliding groove plate 2051.

A conversion member is provided at the bottom end of the sliding groove plate 2051, and a transmission member 204 is provided on the bearing base. The transmission member 204 includes a fixed seat 2041 provided on the bearing base. A second pulley 2042 is rotatably provided on the fixed seat 2041. A first bevel gear 2043 is rotatably provided on the fixed seat 2041. The second pulley 2042 is connected to the first pulley 1091 by a belt drive. The conversion member includes a fixing plate 203 fixedly provided on the bearing base and perpendicular to the fixed box 201. A conversion member 206 is fixed on the fixing plate 203. The conversion member 206 includes a carrier 2061 fixedly provided on the fixing plate 203. A rotating body 2066 is rotatably provided in the carrier 2061. An annular sliding groove is provided on the inner wall of the carrier 2061. The rotating body 2066 is slidably connected to the carrier 2061 through the annular sliding groove. The rotating body 2066 can only perform circumferential rotational motion on the inner wall of the carrier 2061 and cannot perform displacement movement along the radial direction of the carrier 2061. A second bevel gear 2067 is fixed at the bottom end of the rotating body 2066. A curved groove is provided on the rotating body 2066. A sliding body 2062 is fixed at the bottom end of the slider 2052. The sliding body 2062 penetrates through the bottom end of the carrier 2061. Limiting blocks slidably connected to the curved groove are symmetrically fixed on the outer wall of the end of the sliding body 2062 extending into the carrier 2061. A second spring 2063 is also sleeved on the outer wall of the sliding body 2062. A positioning groove is provided on the inner wall of the carrier 2061. A positioning block 2064 is also provided on the outer wall of the sliding body 2062. The sliding body 2062 slides up and down in the positioning groove through the positioning block 2064.

[0050] When the sliding column 2021 of the cutting tool assembly moves horizontally, it drives the limiting body 205 to move. The movement of the limiting body 205 causes the second positioning posts 2053 at both ends of the slider 2052 to slide in the Z-shaped chute 2054, thereby transmitting the linear power to the sliding body 2062. The sliding body 2062 moves up and down in the carrier 2061, and the clamping rod 2065 on its outer wall moves in the curved groove of the rotating body 2066 through the limiting block, driving the rotating body 2066 to rotate. The bevel gear two 2067 at the bottom end of the rotating body 2066 meshes with the bevel gear one 2043, driving the bevel gear one 2043 to rotate, and further causing the pulley two 2042 to rotate.
