Abstract

A motor support on outdoor unit of air conditioner is prepared as forming the first top unit by punching and opening up middle of slab then folding it towards to front and forming the second top unit by punching and opening up middle of the first unit then folding it towards to back; forming said slab by process of blanking, hole punching, shape-pressing, folding and turning-up.

Description

Air conditioner outdoor motor rack

Technical field:

The invention relates to a structural component of an outdoor machine of an air conditioner, in particular to a material-saving electrical frame for an outdoor machine of an air conditioner, which belongs to the transformation technology of an air conditioner.

Background technique:

Existing air conditioner outdoor unit motor frame usually adopts an integral structure as shown in Figure 1, wherein the middle part 2 is used to install the fan motor, the bottom 8 is installed on the base of the outdoor unit, and the two parts of the first top 3 and the second top 4 The ends are respectively fixed on the outdoor unit casing and the condenser. The motor frame of this integral structure is processed by blanking, punching, pressing, bending, flanging and other stamping processes with large plates. The disadvantages are: (1) because the motor frame is usually An integral hollow structure, in which the intermediate material is not effectively used, resulting in material waste; material loss is large: (2) because the first top 3 is formed by bending the entire material after lengthening, the mold volume is large, increasing mold cost.

Invention content:

The object of the present invention is to overcome the above-mentioned disadvantages and provide an air conditioner outdoor motor frame that saves materials and reduces mold costs.

The technical solution of the present invention is to provide a material-saving outdoor motor frame for air conditioners. The motor frame is an integral structure. The first top and the second top are respectively fixed on the shell of the outdoor machine and the condenser. The motor frame is processed from a plate through blanking, punching, pressing, bending, flanging and other stamping processes. It is to punch and take the material from the middle of the first top and bend it backwards.

As a further improvement of the above technical solution, the third top of the motor frame of the outdoor unit of the air conditioner is flanged.

As a further improvement of the above technical solution, reinforcing ribs are pressed on the top of the frame of the outdoor machine of the air conditioner.

As a further improvement of the above technical solution, a positioning card is made at the bottom of the motor frame of the outdoor unit of the air conditioner to facilitate installation and increase stability.

As a further improvement of the above technical solution, the triangular ribs are evenly pressed at all the bends of the motor frame of the outdoor unit of the air conditioner.

Compared with the prior art, the present invention has the following advantages:

(1) material loss is small: because the materials used at the first top and the second top of the motor frame are all taken from the middle part of the plate, the total length of the blanking has been reduced by about 30%, that is to say, the present invention is better than the existing Materials used in technology are saved by about 30%;

(2) Because the total length of blanking is shortened, the volume of the mold is reduced, which reduces the cost of the mold;

(3) The overall strength is good due to the treatment of beading and bending on the motor frame.

Detailed ways

As shown in Figure 3, the motor frame is an integral structure, which is divided into a middle part 2 for installing the fan motor, and a bottom 1 for installing on the base of the outdoor unit, and its first top 3 and second top 4 are respectively fixed on the on the casing of the outdoor unit and the condenser.

The motor frame of the present invention is processed by blanking, punching, profiling, bending, flanging and other stamping processes with a plate of a certain size. The first top 3 is punched out from the middle of the plate and bent upwards, and the second top 4 is bent back from the middle of the first top 3 to form a board. The top 5 of the outdoor motor frame of the air conditioner is flanged, the first top 3 is pressed with reinforcing ribs 6, all the bends are evenly pressed with triangular ribs, the supporting parts 7 on both sides are pressed into a U shape, and the bottom is made to facilitate installation and increase Stable positioning card. Fig. 4 is a blanking development diagram of the present invention. Compared with the blanking development diagram of the prior art shown in FIG. 2 , the blanking size of the present invention is reduced by 30%, and material consumption is greatly saved.
