Abstract

The utility model discloses an edge scraping mould for a turning-avoided half-finished compressor lower casing. The edge scraping mould for the turning-avoided half-finished compressor lower casing is provided with an upper mould base and a lower mould base, wherein a mould shank is installed on the top of the upper mould base, a female mould and an opposite male mould, a guide sleeve and an opposite guide pillar are respectively installed on the upper mould base and the lower mould base, a positioner is installed on the top of the male mould, a stripper plate is sleeved on the male mould, the stripper plate is connected with the lower mould base through a stripper bolt, a part, between the stripper plate and the lower mould base, of the stripper bolt is provided with a stripper spring. The edge scraping mould for the turning-avoided half-finished compressor lower casing is characterized in that the one-sided gap S between the male mould and the female mould is 0.5mm, the top edge of the half-finished compressor lower casing manufactured by the edge scraping mould for the turning-avoided half-finished compressor lower casing tilts towards the outside bottom, the top is flat and the precision meets the requirements when the half-finished compressor lower casing turns into a finished compressor lower casing through stretching, thus turning the top of the compressor lower casing by a turning lathe is needless, time and labor are saved, the production efficiency of the compressor lower casing is improved, and the quality of the manufactured products is ideal.

Description

A kind of half-finished shaving die of turning compressor lower casing of exempting from

Technical field

The utility model relates to the shaving die that the compressor lower casing is cut edge, especially a kind of half-finished shaving die of turning compressor lower casing of exempting from.

Background technology

Generally all through stretching first, cut edge and final this three process of drawing and forming being finished, the compressor lower casing semi-finished product that produce after cutting edge directly affect the quality of final products to the compressor lower casing.Traditional compressor lower casing shaving die includes upper bolster and die shoe, die shank is equipped with at the upper bolster top, die and punch and guide pin bushing and the guide pillar of positioned opposite are housed respectively on upper bolster and the die shoe, a locator is equipped with at the punch top, be set with a stripper on the punch, stripper and die shoe link together by unloading bolt, and the discharging spring is housed between stripper and die shoe on the unloading bolt, and the monolateral gap S between punch and the die is 0.3mm.The compressor lower casing semi-finished product top sides that the compressor lower casing shaving die of this traditional structure is produced is along being vertical structure, the compressor lower casing semi-finished product of this vertical stratification can inwards tilt at its product top through final drawing and forming the time, smooth not, need just can reach through lathe car one cutter the more final requirement of product, so not only waste time and energy, inefficiency, and the compressor lower casing quality of producing is undesirable.Therefore, a kind of half-finished shaving die of turning compressor lower casing of exempting from that can address the above problem well of design extremely is necessary.

Summary of the invention

The purpose of this utility model is exactly problems such as will solving compressor lower casing semi-finished product top sides that traditional compressor lower casing semi-finished product shaving die produces vertical structure causes that its product top can inwards tilt through final drawing and forming the time along being, smooth not, needs pass through final requirement that lathe car one cutter just can reach product again, waste time and energy, inefficiency and the compressor lower casing quality produced are undesirable, and a kind of half-finished shaving die of turning compressor lower casing of exempting from is provided.

Concrete scheme of the present utility model is: improve for traditional half-finished shaving die of compressor lower casing, it has upper bolster and die shoe, die shank is equipped with at the upper bolster top, die and punch and guide pin bushing and the guide pillar of positioned opposite are housed respectively on upper bolster and the die shoe, a locator is equipped with at the punch top, be set with a stripper on the punch, stripper and die shoe link together by unloading bolt, the discharging spring is housed between stripper and die shoe on the unloading bolt, it is characterized in that: the monolateral gap S between described punch and the die is 0.5mm.

The utility model is by increasing to 0.5mm with the gap between the half-finished shaving die convex mould of traditional compressor lower casing and the die by 0.3mm, so that the half-finished top sides of the compressor lower casing of producing is along bottom angled laterally, its top is very smooth when becoming finished product through final stretching, the precision at compressor lower casing top meets the requirements, need not to use lathe again compressor lower casing top to be cut, time saving and energy saving, production efficiency is improved, the product quality that processes is very good, has brought huge economic benefit to enterprise.

Among the figure: 1-die shoe, 2-guide pillar, 3-guide pin bushing, 4-upper bolster, 5-locator, 6-die shank, 7-die, 8-unloading bolt, 9-discharging spring, 10-punch, 11-discharging version, 12-compressor lower casing semi-finished product.

The specific embodiment

Referring to Fig. 1, this is that the structure of cover processing compressor lower casing semi-finished product 12(compressor lower casing semi-finished product 12 is referring to Fig. 3 and Fig. 4) shaving die, the processing of cutting edge of compressor lower casing semi-finished product after being mainly used to stretch first, it has upper bolster 4 and die shoe 1, die shank 6 is equipped with at upper bolster 4 tops, die 7 and punch 10 and guide pin bushing 3 and the guide pillar 2 of positioned opposite are housed respectively on upper bolster 4 and the die shoe 1, a locator 5 is equipped with at punch 10 tops, be set with a stripper 11 on the punch 10, stripper 11 links together by unloading bolt 8 with die shoe 1, between stripper 11 and die shoe 1 discharging spring 9 is housed on the unloading bolt 8, these features are all same as the prior art.Referring to Fig. 2, improvements of the present utility model are that the monolateral gap S between punch 10 and the die 7 is increased to 0.5mm by 0.3mm, cut edge out compressor lower casing semi-finished product 12 top sides like this along bottom angled laterally, its top is very smooth when becoming finished product through final stretching, the precision at compressor lower casing top meets the requirements, and need not to use lathe compressor lower casing top to be cut again, and has reduced by a procedure, time saving and energy saving, production efficiency and crudy all are improved.

The selection of size, specification and the material of die shoe 1 of the present utility model, guide pillar 2, guide pin bushing 3, upper bolster 4, locator 5, die shank 6, die 7, unloading bolt 8, discharging spring 9, punch 10 and discharging version 11; can adjust according to actual needs; these adjustment there is no the change of substantive principle, all belong to protection domain of the present utility model.

Claims

1. exempt from the half-finished shaving die of turning compressor lower casing for one kind, have upper bolster and die shoe, die shank is equipped with at the upper bolster top, die and punch and guide pin bushing and the guide pillar of positioned opposite are housed respectively on upper bolster and the die shoe, a locator is equipped with at the punch top, be set with a stripper on the punch, stripper and die shoe link together by unloading bolt, the discharging spring is housed between stripper and die shoe on the unloading bolt, it is characterized in that: the monolateral gap S between described punch and the die is 0.5mm.
