Description

Technical Field

[0001] This invention relates to a damper cylinder processing device, and more particularly to a single-wheel pusher sealing machine for a thin-walled, compact shock absorber. Background Technology

[0002] Currently, many damper cylinders, in order to save materials and simplify the manufacturing process, often have the cylinder head end internally flanged to form a cylinder head structure with oil seal components and support plates, thus eliminating the need for a traditional cylinder head structure. Therefore, a specialized internal flanged device (cylinder sealing machine) is needed to internally flange the cylinder head end. However, existing conventional internal flanged devices usually use a hydraulic station to drive tilted flanged rollers to press and flange the cylinder end. This type of internal flanged device is bulky, occupies a lot of space, and consumes a lot of energy. Furthermore, because it exerts a lot of force on the outer wall of the cylinder, it is usually only suitable for thick-walled cylinders. When internally flanged on some thin-walled cylinders, it is easy to cause deformation of the outer wall of the cylinder. Moreover, the tilt angle of the flanged rollers is also difficult to adjust. If the tilt angle is too large, it may result in an overly large flange, affecting the internal length space of the cylinder; if the tilt angle is too small, it may result in an underly large flange, making it impossible to cooperate with the oil seal components to form a cylinder head structure.

[0003] Currently, the inner flanging of thin-walled cylinders is usually done manually or with some simple inner flanging devices, which is not only inefficient, but also prone to errors, affecting product quality. Summary of the Invention

[0004] To address the shortcomings and deficiencies of the existing technology, this invention provides a design where the flanging roller is equipped with a flanging step. This eliminates the need for tilting and allows for easy flanging of the cylinder body with a single vertical downward pressure. This design achieves a compact structure, high flanging precision to prevent deformation of the cylinder body, high flanging efficiency, and low production cost. Furthermore, a floating plate drive cylinder is used to drive the floating plate downward to provide downward pressure to the flanging roller and the flanging guide roller. This design is simple, occupies a small area, and offers fast downward pressure and high efficiency, making it ideal for single-wheel push-roller sealing machines used in thin-walled, compact shock absorbers for flanging within thin-walled cylinder bodies.

[0005] The technical solution of the present invention: A single-wheel push-roller sealing machine for thin-walled and compact shock absorbers, comprising a support and pressing assembly, a cylinder positioning and rotating assembly mounted on the support and pressing assembly, a flanging roller assembly cooperating with the cylinder positioning and rotating assembly, and a flanging guide roller assembly cooperating with the flanging roller assembly.

[0006] The support pressing assembly includes a support base plate, a support top plate, several support columns connected between the support base plate and the support top plate, a floating plate slidably connected to the support columns, and a floating plate drive cylinder that drives the floating plate to slide up and down. The floating plate is connected to the support columns through a linear bearing, and the floating plate drive cylinder is connected to the floating plate through a floating bracket. One side of the floating plate is provided with an operating port for cooperating with the flange roller assembly and the flange guide roller assembly.

[0007] The cylinder positioning and rotating assembly includes a cylinder positioning shaft and a rotary drive motor for driving the cylinder positioning shaft to rotate. Both the cylinder positioning shaft and the rotary drive motor are mounted on a support base plate.

The flanging guide roller assembly includes a flanging guide roller and a guide roller drive cylinder for driving the flanging guide roller to move back and forth. The flanging roller is provided with a downward-facing flanging step. Both the flanging roller assembly and the flanging guide roller assembly are mounted on a floating plate.

[0009] This invention designs the flanging roller with a flanging step structure, so that it does not need to be tilted. It only needs to provide a vertical downward pressure to easily achieve the inner flanging of the cylinder body. On the one hand, it can achieve a compact structure, and on the other hand, it has high flanging accuracy, which can prevent the outer wall of the cylinder from deforming. At the same time, it has high flanging efficiency and low production cost. At the same time, a floating plate driving cylinder is used to drive the floating plate to press down to provide downward pressure to the flanging roller and the flanging guide roller. The structure is simple, occupies a small area, and has a fast pressing speed and high efficiency, making it very suitable for flanging processing inside thin-walled cylinders.

[0011] This structure ensures the reliable installation of the floating plate drive cylinder and the floating bracket, as well as the stability of the connection between them; making the overall structure simple and compact, while providing stable and reliable support.

[0012] Preferably, the floating support includes a connecting plate and two connecting columns fixed to the bottom of the connecting plate. The bottoms of the two connecting columns are respectively fixed to both sides of the operating port and located inside the linear bearing.

[0021] This structure ensures that the flanging roller is installed firmly and reliably, and that the roller drive cylinder drives the flanging roller to move back and forth smoothly and reliably; it also ensures that the flanging roller's compression of the cylinder to form an inner flanging is more stable and reliable.

[0022] Preferably, the guide wheel drive cylinder is connected to a guide wheel bracket for mounting a flanged guide wheel.

[0027] This structure further ensures that the roller-driven cylinder drives the flanging roller to move back and forth, and the guide roller-driven cylinder drives the flanging guide roller to move back and forth smoothly and reliably.

[0028] This invention designs the flanging roller with a flanging step structure, so that it does not need to be tilted. It only needs to provide a vertical downward pressure to easily achieve the inner flanging of the cylinder body. On the one hand, it can achieve a compact structure, and on the other hand, it has high flanging accuracy, which can prevent the outer wall of the cylinder from deforming.
