Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile processing, and in particular to an extrusion device for aluminum profiles used in automotive air suspension bushings. Background Technology

[0002] Air suspension is a common method of shock absorption in automobiles today, mainly used in trailers, trucks, and buses. It reduces bumps and vibrations during driving, mitigating the impact on the vehicle body. A protective cover is installed on the outside of the air suspension, and a protective sleeve is fitted over this cover. An aluminum profile-supported sleeve is located in the center of this protective sleeve to enhance the protective effect.

[0003] The existing extrusion equipment for aluminum alloy profiles used in protective sleeves has poor processing performance, and the extrusion equipment for aluminum alloy profiles used in protective sleeves needs to be improved and optimized. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of poor processing effect in the prior art and provides an extrusion device for aluminum profiles for automotive air suspension covers with good processing effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an extrusion device for aluminum profiles used in automotive air suspension bushings, comprising: An extrusion cylinder, wherein a movable assembly capable of moving the extrusion cylinder is installed at its lower end; A forming die, wherein the forming die is installed at the rear end of the extrusion cylinder and a top cylinder is connected to the outside of the forming die; An extrusion rod is sleeved with an insertion rod, and an extrusion cylinder is connected to the front end of the extrusion rod. Both the extrusion rod and the insertion rod are connected to the extrusion cylinder. An end cutter is provided, which is located at the top of the extrusion cylinder and is connected to a telescopic hydraulic cylinder.

[0006] The extrusion device includes an extrusion cylinder with a moving assembly at its lower end. This moving assembly drives the extrusion cylinder to move horizontally. A forming die is installed inside the extrusion cylinder at its rear end, and a top cylinder is located on the outside of the forming die to support it, ensuring stability during extrusion and guaranteeing the extrusion forming effect. An extrusion rod has a mounting hole in its middle for installing an insert rod, which serves as the core of the forming die. The insert rod protrudes and engages with the forming die to form a forming cavity. An extrusion cylinder is located at the front end of the extrusion rod, and this cylinder is a hydraulically driven cavity. Both the insert rod and the extrusion rod are connected to the extrusion cylinder. During extrusion forming, the extrusion cylinder first pushes the insert rod towards the forming die, then pushes the insert rod and the extrusion rod to move synchronously, completing the extrusion forming process. An end cutter is installed above the extrusion cylinder. The end cutter is connected to a telescopic hydraulic cylinder. The telescopic hydraulic cylinder moves downward to cut the end of the extruded main tube to obtain the main tube, so as to facilitate subsequent shaping processing of the main tube and ensure good forming effect of the aluminum profile.

[0007] Preferably, the moving assembly includes a moving chute, within which a moving slider is slidably connected. The top of the moving slider is connected to the extrusion cylinder. A second telescopic hydraulic cylinder is installed on the outside of the moving chute and connected to the moving slider. Specifically, the moving assembly includes a moving chute, with the end of which is connected to the second telescopic hydraulic cylinder. The moving slider is installed inside the moving chute and connected to the telescopic end of the second telescopic hydraulic cylinder. The telescopic movement of the second cylinder moves the moving slider. Simultaneously, the moving slider is connected to the extrusion cylinder. This structure allows the extrusion cylinder to move after the main tube has been extruded. This movement facilitates the downward movement of the end cutter to cut the main tube, completing the processing of the main tube. This structure facilitates the processing of the main tube and improves the processing effect.

[0008] Preferably, a heating sleeve is fitted onto the outer side of the extrusion cylinder. The heating sleeve is an arc-shaped piece, and a telescopic cylinder is connected to the outer side of the heating sleeve. The heating sleeve, which is an arc-shaped piece, is mounted on the outer side of the extrusion cylinder. The telescopic cylinder can drive the heating sleeve to contact and engage with the extrusion cylinder, allowing the heating sleeve to heat the extrusion cylinder, ensuring thermal compensation during extrusion and guaranteeing good extrusion molding results.

[0009] Preferably, a support plate is provided at the front end of the extrusion cylinder. The support plate is an arc-shaped plate, and a telescopic cylinder is provided at the lower end of the support plate. The arc-shaped support plate at the front end of the extrusion cylinder and the telescopic cylinder at its lower end can lift the heated aluminum ingot, facilitating the extrusion rod to push the ingot into the extrusion cylinder, thus completing the extrusion forming of the main tube. This structure makes the extrusion forming operation convenient and simple, improving the processing effect.

[0010] Preferably, the extrusion rod has a fixing ring at its end with several fixing holes. An adjusting ring is slidably fitted onto the extrusion rod, and an adjusting rod is connected to the adjusting ring. The adjusting rod is inserted into the fixing holes. A connecting platform is connected to the end of the insertion rod, and the connecting platform is connected to the adjusting rod and the extrusion cylinder. Specifically, the fixing ring at the end of the extrusion rod has several fixing holes, and the adjusting ring is fitted onto the extrusion rod, allowing it to slide along the rod. The adjusting rod is mounted on the adjusting ring, passing through the fixing holes and connecting to the connecting platform at the end of the insertion rod. This structure guides the insertion rod as it is pushed towards the forming die, ensuring stable pushing and allowing the insertion rod to drill holes in the aluminum ingot inside the extrusion cylinder. This allows the insertion rod and the forming die to combine to form an extrusion forming cavity, ensuring good extrusion processing results.

[0011] Preferably, a stabilizing spring is connected between the fixed ring and the adjusting ring, and the stabilizing spring is sleeved with the adjusting rod. This structure allows the connecting platform to contact the end of the extrusion rod after the extrusion cylinder pushes the insert rod towards the forming die. As the extrusion cylinder continues to push the extrusion rod, the extrusion rod can extrude the aluminum ingot, completing the extrusion forming of the main tube, thus ensuring a good extrusion processing effect.

[0012] Preferably, the top cylinder sidewall is provided with several cooling holes, which are connected to cooling pipes, and the cooling pipes are externally connected to a cooling pump. A drain hole is provided at the lower end of the top cylinder sidewall, and the cooling holes on the sidewall are externally connected to cooling pipes, which are in turn connected to a cooling pump. This cooling pump can be a liquid-cooled pump or an air-cooled pump. When liquid cooling is required, water can be sprayed into the top cylinder to cool the extruded main tube. When air cooling is required, cold air can be sprayed into the top cylinder to cool the extruded main tube. This structure ensures good cooling effect, guarantees the quality of the extruded main tube, and thus ensures good processing results.

[0013] Preferably, the top end of the insert rod is provided with a beveled insertion hole. This beveled insertion hole facilitates drilling of the aluminum ingot, thereby improving the extrusion molding effect.

[0014] The beneficial effects of this utility model are: ensuring the quality of extrusion molding, ensuring good extrusion processing effect, and ensuring good performance of the device. Attached Figure Description

[0032] The support plate 32 at the front end of the extrusion cylinder 3 is an arc-shaped plate. A telescopic cylinder 33 is provided at the lower end of the support plate 32.
