Machining device for cutting off mechanical parts of household appliances

Abstract

The invention relates to a machining device for cutting off mechanical parts of household appliances. The machining device comprises a rack, the rack is provided with a positioning base and a cuttingsaw, the cutting saw is located above the positioning base, the rack is fixedly provided with a piston cylinder, the piston cylinder is internally and slidingly connected with a push rod, a first spring is connected between the push rod and the piston cylinder, and a rotating shaft is rotatably connected to the end, away from the piston cylinder, of the push rod; the cutting saw is fixed on the rotating shaft, the side, away from the push rod, of the piston cylinder is communicated with an air inlet pipe, the rack is fixedly provided with an air pump, the air inlet pipe is provided with a valve, and the rack is also provided with a delay mechanism for delaying and enlarging the opening degree of the valve; compared with the prior art, the machining device has the advantages that through the arrangement of the push rod, the delay mechanism, the cutting saw and the like, the damage caused by sputtered scraps to operators is avoided, the offset of a heat dissipation column during cuttingis avoided, and more time and labor are saved in the whole manufacturing process.

Description

technical field [0001] The invention belongs to the field of accessory cutting equipment, in particular to a processing device for cutting off mechanical accessories of household electrical appliances. Background technique [0002] During the production process of the cooling column of the refrigerator, firstly, a long cooling column is cast through the casting device, and secondly, the entire cooling column is cut into several equal parts on average by the cutting device; during the cutting process, There is a cutting device in the prior art, which includes a frame, on which a positioning seat and a cutting saw are arranged, and the cutting saw is hinged on the positioning seat, and the cutting saw is driven by a motor; On the positioning seat, start the motor, the motor drives the cutting saw to rotate, and finally the operator swings the cutting saw to cut the cooling column. [0003] The above device has completed the equal cutting of the heat dissipation column, but th...

AI Technical Summary

Problems solved by technology

[0003] The above device has completed the equal cutting of the heat dissipation column, but there are still the following problems: 1. This device requires the operator to control the cutting saw. When the cutting saw cuts the heat dissipation column, the operator is close to the heat dissipation column. The debris will be easily splashed on the operator and cause injury to the operator; 2. This device also takes a long time to cut the heat dissipation column, which will easily cause the heat dissipation column to deviate and cause the cutting surface of the heat dissipation column to produce a slope , causing the cutting surface to be uneven, and the cutting surface needs to be polished, which increases the production steps and is time-consuming and laborious
