Abstract
The invention discloses a machining method for an inner top longitudinal beam of an automobile. The method comprises the following steps of 1) performing blanking on a punching machine A by using a blanking die to obtain a blanking size required by the formation of a product; 2) placing two blanked semi-finished products on a left part forming die and a right part forming die on a punching machine B for forming respectively to obtain formed parts of which the shape and the dimensional accuracy meet the requirements of the product; 3) correspondingly placing the left and right formed semi-finished products on a left part trimming die and a right part trimming die for trimming respectively; 4) placing the left and right trimmed semi-finished products on a left part flanging forming die and a right part flanging forming die on a punching machine C for flanging forming respectively to obtain a final product shape; and 5) closing and placing the left and right flanged-formed semi-finished products in a middle left and right part punching die for punching. The machining method is convenient to operate, and is applied to the field of machining of automobile fittings, the production efficiency is improved, the production cost is lowered, and the labor intensity of an operator is reduced.
Description
Technical field
The present invention relates to the manufacture field of auto parts machinery, relate in particular to the processing method of automobile top interior beam.
Background technology
The automobile top interior beam is originally by blanking die (about part share), shaping mould, trimming die, curring and sizing die, perforating die and is stamped to form.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 to save cost, reduces cost of goods manufactured.The mould that the top interior beam 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 purpose of this invention is to provide a kind of easy to operately, can enhance productivity the processing method of the automobile top interior beam that reduces production costs.
The present invention is achieved in that the processing method of automobile top interior beam, it is characterized in that: may further comprise the steps: 1) carry out blanking with blanking die on punch press A, obtain the required blanking size of product shaping; 2) semi-finished product that two blankings got off are placed on respectively on upper left shaping mould of punch press B and right shaping mould and carry out moulding, obtain the profiled member that shape, dimensional accuracy meet product requirement; 3) the left and right semi-finished product after the moulding are put into respectively on corresponding left trimming die and right the trimming die, carried out deburring; 4) the left and right semi-finished product after the deburring are placed on respectively on left the curring and sizing die and right curring and sizing die on the punch press C, carry out flanging and restriking, obtain the final products profile; 5) with the left and right semi-finished product behind the flanging and restriking to be combined in the middle of putting into about the part perforating die carry out punching.
During deburring, the deburring burr is not more than 0.5mm in the step 4) of the present invention.
During punching, punching burr is not more than 0.3mm in the step 5) of the present invention.
The present invention is easy to operate, has improved production efficiency, has reduced production cost, has reduced operative employee's labour intensity.

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing:
With reference to accompanying drawing, the processing method of automobile top interior beam is characterized in that: may further comprise the steps: 1) carry out blanking with blanking die on punch press A, obtain the required blanking size of product shaping; 2) semi-finished product that two blankings got off are placed on respectively on upper left shaping mould of punch press B and right shaping mould and carry out moulding, obtain the profiled member that shape, dimensional accuracy meet product requirement; 3) the left and right semi-finished product after the moulding are put into respectively on corresponding left trimming die and right the trimming die, carried out deburring; 4) the left and right semi-finished product after the deburring are placed on respectively on left the curring and sizing die and right curring and sizing die on the punch press C, carry out flanging and restriking, obtain the final products profile; 5) with the left and right semi-finished product behind the flanging and restriking to be combined in the middle of putting into about the part perforating die carry out punching.During deburring, the deburring burr is not more than 0.5mm in the described step 4).During punching, punching burr is not more than 0.3mm in the described step 5).During implementation, the present invention mainly provides two pairs of multi-station molds: moulding trimming die, flanging and restriking perforating die.Moulding in the former operation, deburring are combined into an operation finish at the moulding trimmer, flanging and restriking, punching are combined into an operation finish at the flanging and restriking perforating press.First set mould punching semi-finished product out are by punching out in manual mode feeding to the second mold.The manufacturing process of these two pairs of moulds is as follows: at first the punch die still by old processes, is directly processed at CNC by product data.Adopt same pair of mould bases during the assembling of the die cavity of moulding, deburring, adopt same pair of mould bases during the die cavity assembling of flanging and restriking, punching, and these two pairs of moulds all be about part share mould.Like this requirement of number of devices and operative employee's quantity reduced.
