Abstract

The invention discloses a machining method for a rear wheel cover of an automobile. The machining method is characterized by comprising the following steps of 1) placing a plate material on a blanking die of a blanking machine, and performing blanking to obtain a blanking size required by the formation of a product; 2) placing a blanked semi-finished product in a stretching die of a stretcher, and performing stretching to obtain a stretched part of which the stretched shape and the dimensional accuracy meet the requirements of the product; and 3) placing the stretched semi-finished product on a trimming and punching die of a four-station punching machine, transferring the semi-finished product on a side trimming and punching die after the semi-finished product is trimmed and punched, transferring the semi-finished product on a hole flanging forming die after the semi-finished product is side trimmed and punched, and transferring the semi-finished product on a punching die for punching after the semi-finished product is hole flanged-formed. The machining method is convenient to operate, and is applied to the machining of automobile fittings, the production efficiency is improved, the production cost is lowered, the utilization rate of equipment is increased, and the labor intensity of an operator is reduced.

Description

The processing method of automobile rear-wheel cover
Technical field
The present invention relates to the manufacture field of auto parts machinery, relate in particular to the processing method of automobile rear-wheel cover.
Background technology
The rear wheel cover of body of a motor car afterbody is left and right symmetrical part, and its original technique is blanking, stretching, trimming and piercing die, side trimming and piercing die, hole flanging shaping, punching 6 road stamping procedures, needs 6 punch presses.Along with the develop rapidly of car industry, particularly the expansion of household small-size automobile market and cost descend in the urgent need to, each large main engine plants requires economical with materials, reduces production costs, and improves the utilization rate of equipment.The mould that the rear wheel cover of old technique is made is many, equipment needed thereby quantity is many mainly with the quantity that reaches the operative employee, but production efficiency is not high, has virtually increased production cost.
Summary of the invention
The processing method that the purpose of this invention is to provide a kind of automobile rear-wheel cover, this mould structure is reasonable, and is easy to operate, can reduce punch press quantity, enhances productivity, and reduces production costs.
The present invention is achieved in that the processing method of automobile rear-wheel cover, it is characterized in that: may further comprise the steps: 1) plate is put on the blanking die of blanker and carried out blanking, obtain the required blanking size of product shaping; 2) semi-finished product of the blanking stretching die of putting into stretching-machine stretches, and obtains the tensioning member that tension shape, dimensional accuracy meet product requirement; 3) semi-finished product after will stretching are put on the trimming and piercing die on the four station punch presses, move into behind the trimming and piercing die on the side trimming and piercing die, move into behind the side trimming and piercing die on the hole flanging sizing die, move on the perforating die after the hole flanging shaping and carry out punching.
Step 2 of the present invention) stretching depth is between the 105%-115% of the final products degree of depth in.
The deburring burr is not more than 0.5mm in the step 3) of the present invention, and punching burr is not more than 0.3mm.
The present invention is rational in infrastructure, and is easy to operate, can reduce punch press quantity, enhances productivity, and reduces production costs.
The specific embodiment
The processing method of automobile rear-wheel cover is characterized in that: may further comprise the steps: 1) plate is put on the blanking die of blanker and carried out blanking, obtain the required blanking size of product shaping; 2) semi-finished product of the blanking stretching die of putting into stretching-machine stretches, and obtains the tensioning member that tension shape, dimensional accuracy meet product requirement; 3) semi-finished product after will stretching are put on the trimming and piercing die on the four station punch presses, move into behind the trimming and piercing die on the side trimming and piercing die, move into behind the side trimming and piercing die on the hole flanging sizing die, move on the perforating die after the hole flanging shaping and carry out punching.Described step 2) stretching depth is between the 105%-115% of the final products degree of depth in.The deburring burr is not more than 0.5mm in the described step 3), and punching burr is not more than 0.3mm.During implementation, the present invention finishes trimming and piercing die, side trimming and piercing die, hole flanging shaping, punching 4 procedures at a punch press, reduced punch press quantity and floor space, considers simultaneously the factors such as utilization rate that improve blank, and mould structure adopts flip-over type.Cut part can be used for processing some findings in the trimming and piercing die operation, not exclusively does waste disposal, has improved the blank utilization rate and has been about 15%.Reduced the development cost of mould.Reduce quantity and the floor space of punch press, reduced the operator, reduced workman's labour intensity.

Claims (3)
