Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to the technical field of a traction device manipulator for aluminum profile extrusion. Background Art

[0002] Aluminum profiles are objects with certain geometric shapes made from aluminum as raw material and a material with certain strength and toughness through processes such as rolling and extrusion of aluminum bars. Especially in the extrusion process, a traction device is required to pull the extruded aluminum product to the end of the roller frame.

[0003] Traction is one of the most important links in the aluminum extrusion production process. When extruding aluminum profiles, the friction between the aluminum ingot and the extrusion die (extrusion cylinder, die, extrusion pad, etc.) causes the flow velocity of the aluminum ingot to be uneven along the cross-section during the extrusion process. Using a tractor to pull the aluminum profile can eliminate the problem of uneven flow velocity, so that the flow of the product along the cross section is more uniform.

[0004] At present, the traction device usually uses its upper and lower fixing plates to clamp and fix the formed aluminum profiles. However, when clamping and fixing thinner and special-shaped aluminum profiles, when the clamping force of the upper and lower fixing plates is too large, the aluminum profiles are easily deformed. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a traction device manipulator for aluminum profile extrusion. It can realize the individual clamping and fixing of various parts of various aluminum profiles according to their stress conditions, avoiding the deformation of aluminum profiles during clamping and fixing, and the device can adjust the clamping force of each point according to different aluminum profile characteristics, without changing the manipulator, saving costs and greatly improving the product qualification rate.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A traction device manipulator for aluminum profile extrusion includes a bottom plate, a vertical arm, a cylinder, a first push rod, a screw rod, a second push rod and a shaft, wherein the bottom plate is fixedly mounted on the lower end of the vertical arm, a bracket is fixedly mounted on the upper end of the vertical arm, the cylinder is fixedly mounted on the bracket, a telescopic rod of the cylinder passes through the bracket and a lifting platform is fixedly mounted, the lifting platform opens downward, a row of first holes is opened at the rear end of the lifting platform, a main spring is movably placed in the first hole, a first square tube connected to the first hole is arranged on the lifting platform at the lower end of the first hole, the first push rod is movably mounted in the first square tube and the first hole, the upper end of the first push rod is in contact with the main spring, The upper opening of the first hole is provided with an internal thread, and the screw is meshedly installed on the internal thread at the upper opening of the first hole and contacts with the main spring. A second hole in a row is provided at the front end of the lifting platform, and a reset spring is movably placed in the second hole. A second square tube connected with the second hole is arranged on the lifting platform at the lower end of the second hole. The second push rod is movably installed in the second square tube and the second hole, and the upper end of the second push rod is in contact with the reset spring. The shaft is fixedly installed on the two side walls of the lifting platform, and rows of claws are rotatably installed on the shaft, and the front and rear ends of the row of claws correspond to and contact with the lower ends of the second push rod and the first push rod respectively.

[0008] Preferably, the first holes are arranged in staggered rows.

[0009] Preferably, the first push rod is provided with scale marks.

[0010] The beneficial effects that can be achieved by the utility model using the above technical solution are:

[0011] 1. By arranging springs and push rods at the front and rear ends of the lifting platform respectively, an adjustable screw is arranged on the main spring, the springs and push rods at both ends define the position of the claws, and by adjusting the screws on the main springs respectively, different clamping forces of each claw can be achieved.

[0012] 2. By setting scale marks on the first push rod, the force that needs to be adjusted for each claw is obtained through experiments on each aluminum alloy profile, and the scale marks are recorded. When this aluminum alloy profile is produced later, the corresponding main spring force can be obtained by directly adjusting the screw.

[0013] 3. By fixing the lifting platform on the telescopic rod of the cylinder, when the aluminum alloy needs to be clamped and fixed, the telescopic rod of the cylinder will move the adjusted lifting platform from top to bottom close to the bottom plate. When the telescopic rod reaches the lowest position, the claws at the lower end of the lifting platform will clamp and fix various parts of the aluminum alloy respectively, thereby protecting and fixing the aluminum alloy.
