Description

Technical Field

[0001] The present invention belongs to the technical field of metal product processing and manufacturing, and more specifically, particularly relates to a forward and reverse extrusion device for processing metal aluminum products. Background Art

[0002] Metal products are often used in today's life. The metal products industry includes structural metal products manufacturing, metal tool manufacturing, container and metal packaging container manufacturing, stainless steel and similar daily metal products manufacturing, etc. Among them, aluminum profiles are one of the metal materials. It is a kind of metal material with relatively low density, but relatively high strength, which has exceeded high-quality steel, and good plasticity. It can be processed into various profiles. When the aluminum profile is molded, it needs to be extruded to change its own structural shape. It is usually implemented through two steps of positive extrusion and reverse extrusion. Positive extrusion means that the flow direction of the metal is the same as the movement direction of the extrusion rod. During the extrusion process, there is relative sliding between the metal ingot and the inner wall of the extrusion barrel, and there is a large external friction force, so the extrusion force is very large; reverse extrusion means that the flow direction of the metal is opposite to the movement direction of the extrusion rod. There is no relative movement between the metal ingot and the extrusion barrel, so there is no external friction. Positive extrusion and reverse extrusion are used to form metal products, but the effects brought by their extrusion methods are completely different.

[0003] Similar to the current metal products, aluminum profiles still have the following shortcomings when they are formed by forward extrusion and reverse extrusion: when the aluminum profile is pressurized, it is necessary to select a forward extrusion device or a reverse extrusion device to implement it. In this way, the scheduling of aluminum blanks in daily processing will be cumbersome and it cannot be quickly pressurized.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a forward and reverse extrusion device for processing metal aluminum products is provided, in order to achieve a more practical purpose. Summary of the invention

The front end inner rod position of the pneumatic cylinder is fixedly connected to the middle position of the rear end of a rectangular forward push plate, and the forward push plate is slidably connected to four limit sliding rods. A circular forward push block is provided in the middle position of the front end of the forward push plate, and the forward push block is located directly behind the discharge port.

[0007] Optionally, the top end surface of the push plate is fixedly connected to the bottom end surface of the extension plate, a diamond groove is opened at the front end position of the extension plate, and an extrusion rod is fixedly connected to the middle position of the diamond groove, and the front end surface of the extension plate is fixedly connected to a circular ring, and the extrusion rod is located in the middle position inside the guard ring.

[0008] Optionally, a transmission motor A is fixedly connected to the lower front end of the anti-extrusion frame, a spiral transmission worm is provided at the rear end of the transmission motor A, and the rear end of the transmission worm is rotatably connected to the lower rear end of the anti-extrusion frame.

At this time, the traction manipulator is released from the restraint on the aluminum billet, and the aluminum billet itself is fixed by the cooperation of the forward push block and the forward extrusion frame. When the pneumatic cylinder continues to move forward, the forward push block pushes the aluminum billet to extrude it, completing the implementation steps of the forward extrusion.

[0016] In addition, the aluminum billet is placed at the front end position of the extrusion rod through the robot traction equipment. Next, the forming die that needs to be formed and adapted is fixed in the middle position between the inner gear plate of the gate plate and the outer gear plate of the limit frame sliding frame.

Through the cooperation of the transmission worm and the semicircular groove spiral pattern of the transmission block, the moving frame drives the limit frame to move to the rear position as a whole, and the aluminum billet is extruded by moving the forming die backward to complete the reverse extrusion step.

[0026] When in use: first assemble the overall components of the device through the connection relationship mentioned in the embodiment. After the overall assembly of the device is completed, move the position of the support base 1 to a relatively flat ground position. When the metal product aluminum profile needs to be extruded, first adjust the telescopic position of the pneumatic cylinder 202 so that the pneumatic cylinder 202 is in a retracted state, thereby making the position of the forward push plate 203 located at the inner rear position of the forward extrusion frame 2. According to the position of the forward push plate 203, the position of the extension plate 3 is located at the upper rear position of the forward extrusion frame 2, thereby maximizing the extrusion space inside the forward extrusion frame 2 and the distance between the extension plate 3 and the reverse extrusion frame 4.
