Aluminum bar length measurement hot-shear device having double-shearing function and application thereof

Abstract

The invention discloses an aluminum bar length measurement hot-shear device having a double-shearing function and application thereof. The aluminum bar length measurement hot-shear device comprises a hot-shear machine, a photoelectric switch, a short bar storage table, a first measurement device, a second measurement device arranged on the other side of the hot-shear machine and PLC connected with the hot-shear machine, the photoelectric switch, the first measurement device and the second measurement device respectively. The first measurement device comprises a first motor, a first encoder, a first lead screw, a first moving block and a pushing air cylinder arranged on the first moving block. The photoelectric switch is arranged on the first moving block. The second measurement device comprises a second motor, a second lead screw, a second encoder, a second moving block and a limiting baffle arranged on the second moving block. A magnetic switch is arranged on the second moving block. The aluminum bar length measurement hot-shear device has the advantages of saving materials and labors, achieving automatic machining and improving working efficiency and the rate of finished products.

Description

technical field [0001] The invention relates to the field of hot shears or hot saws for aluminum rods, in particular to a hot shear device for measuring the length of aluminum rods and having double shearing functions and its application. Background technique [0002] At present, when processing aluminum materials on the market, the aluminum rods need to be cut to length and hot-sheared before they can be sent into the extrusion machine to be extruded into aluminum profiles. The traditional method is to use the encoder to measure multiple long aluminum rods to be cut, and then transmit the data signal to the PLC controller, and then the PLC controller will send the command to the hot shear machine for the set cutting length. Finally, the rod cutting work is performed by hot shears. Since the aluminum profile extrusion production process is to put the fixed-length hot aluminum rod into the aluminum extrusion machine for extrusion molding, it is required that the length speci...

Problems solved by technology

Then the specification required for the aluminum profile is 8000mm for each section, so there will be 36000-4*8000=4000mm of aluminum profiles, resulting in 4000mm waste, and the use of 4000mm waste for production will consume labor, production equipment time, and electricity. Wait

[0004] In addition, the traditional long rod length detection process is before the heating process. During the production process, it is often necessary to replace and exchange aluminum rods of different sizes or different alloy types due to different orders. The rod is taken away, which leads to the confusion of the parameters automatically set in advance by the PLC control system; and the traditional aluminum rod fixed-length and thermal shearing equipment has no double shearing function, resulting in waste of rods, poor measurement accuracy, and poor system adaptability.
