Description

Technical Field

[0001] The utility model relates to the technical field of extruders, and particularly relates to a piston type aluminum extruder. Background Art

[0002] The extruder is the main equipment for the production of tubes, bars, and profiles of light alloys (aluminum alloys, copper alloys, and magnesium alloys). The main cylinders of traditional small extruders all adopt plunger cylinders, and cooperate with a filling valve and two auxiliary cylinders to meet the speed requirements during the extrusion process. The structure is complex, the number of components is large, and the control requirements are high. During extrusion, the extrusion force is composed of the combined force of the main cylinder and two auxiliary cylinders. When the output of one of the oil cylinders is unstable, the extrusion quality will be affected. Therefore, an oil cylinder that can replace the plunger cylinder for work is needed to improve the extrusion quality. In view of the above problems, a solution is proposed below. Content of the Utility Model

[0003] The purpose of the utility model is to provide a piston type aluminum extruder, which solves the problems raised in the above background art.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A piston type aluminum extruder includes a main cylinder and a piston rod slidably arranged in the main cylinder. One end of the piston rod located in the main cylinder is provided with a first piston, one end of the first piston is provided with a second piston, a piston guide sleeve is installed on the outer wall of the second piston, and a piston locking nut is further installed at the end of the second piston away from the first piston. The piston locking nut is threadedly connected to the piston rod. A right-angle flange is installed at the end of the main cylinder away from the piston rod, and an oil inlet / outlet one communicating with the inner wall of the main cylinder is opened on the right-angle flange. A high-diameter flange is further installed at the other end of the main cylinder, and an oil inlet / outlet two communicating with each other is opened between the high-diameter flange and the main cylinder. The oil inlet / outlet two communicates with the inside of the main cylinder. One end of the main cylinder is further provided with a main cylinder head, and a cylinder head gland is further installed on the main cylinder head.

[0006] Preferably, a connecting flange is further installed at the end of the piston rod, a flange gland is installed on the connecting flange, and an extrusion beam is further installed on the piston rod, the connecting flange, and the flange end cover.

[0007] Preferably, two right-angle flanges are installed in total, and oil inlet / outlets one are opened on both right-angle flanges.

[0008] Preferably, a first V-shaped sealing ring is installed at one end of the first piston and the second piston close to the piston guide sleeve.

[0009] Preferably, a second sealing ring is further installed between the main cylinder head and the piston rod.

[0010] Beneficial effects: The piston-type oil cylinder can reciprocate on its own by reversing the hydraulic fluid. Compared with the plunger cylinder, it does not require an auxiliary oil cylinder; without an auxiliary oil cylinder and a filling valve, the structure is simpler and the control is more convenient; during the extrusion process, only the main oil cylinder exerts force, and the machine runs more smoothly; in order to meet the speed requirements during extrusion, two oil inlets and outlets are arranged in the rodless cavity to achieve rapid flow of the hydraulic fluid.

All technical solutions within the idea of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0015] See Figures 1 to 2 As shown, a piston-type aluminum extrusion machine includes a main cylinder 1 and a piston rod 2 slidably disposed in the main cylinder 1. One end of the piston rod 2 located in the main cylinder 1 is provided with a piston one 3, one end of the piston one 3 is provided with a piston two 4, a piston guide sleeve 5 is mounted on the outer wall of the piston two 4, and a piston locking nut 6 is further mounted at the end of the piston two 4 away from the piston one 3. The piston locking nut 6 is threadedly connected to the piston rod 2, and the piston one 3 and the piston two 4 are fixedly pressed through the piston locking nut 6. V-shaped seal rings one 15 are mounted at the ends of the piston one 3 and the piston two 4 close to the piston guide sleeve 5, and the V-shaped seal rings 15 are used to prevent internal leakage of the oil cylinder.

[0016] One end of the master cylinder 1 away from the piston rod 2 is installed with a right-angle flange 7. An oil inlet / outlet 8 communicating with the inner wall of the master cylinder 1 is provided on the right-angle flange 7. There are two right-angle flanges 7 installed in total, and the oil inlet / outlet 8 is provided on both right-angle flanges 7. When starting the piston cylinder, oil is supplied to the two oil inlet / outlets 8 through an external oil pipe, so that the piston rod 2 can perform a piston movement in the chamber of the master cylinder 1. By setting the design of double oil ports, the rapid flow of oil can be realized.

[0017] On the other end of the master cylinder 1, a high-diameter flange 9 is also installed. An oil inlet / outlet 2 10 communicating with each other is provided between the high-diameter flange 9 and the master cylinder 1. The oil inlet / outlet 2 10 communicates with the inside of the master cylinder 1. On one end of the master cylinder 1, a master cylinder head 11 is also installed, and a cylinder head gland is also installed on the master cylinder head 11. By installing the master cylinder 1 head and the cylinder head gland, the sealing of the master cylinder 1 is realized to prevent leakage. A second sealing ring 16 is also installed between the master cylinder 1 head and the piston rod 2. Through the second sealing ring 16, the sealing is further realized. When the piston rod 2 needs to retract, the oil inlet / outlet 2 10 supplies oil to the inside of the master cylinder 1 through an external oil pipe, and the two oil inlet / outlets 8 quickly discharge oil, so as to realize the movement of the piston rod 2.

[0018] A connecting flange 12 is also installed at the end of the piston rod 2. A flange gland 13 is installed on the connecting flange 12. An extrusion beam 14 is also installed on the piston rod 2, the connecting flange 12 and the flange gland 13. By means of the connecting flange 12 and the flange gland 13, the installation of the extrusion beam 14 is realized. The extrusion beam 14 can realize the extrusion of parts.

[0019] As certain terms are used in the specification and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but use the difference in functions of components as the criterion for distinction. As the term "comprising" mentioned throughout the specification and claims is an open-ended term, it should be interpreted as "comprising but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
