Abstract

The utility model relates to a continuous-forming die device of an iron slot bone of an umbrella. A whole roll of sheet materials for making the iron slot bone of the umbrella is sent into a continuous punching die through a feed device. A cutting device is fixed in an upper die seat and a lower die seat of the utility model to cut and punch the whole roll of sheet materials. Cut material sheets are bent and formed through a punching device, and then the bent and formed material sheets are pressed at the edges and are formed by a pushing and pressing device. Finally, the finished product of the iron slot bone of the umbrella is finished after the material sheets are withdrawn from the die. The whole manufacturing process is completely and automatically formed by a punching and forming machine, the labor cost is saved, and the iron slot bone of the umbrella can be rapidly mass-produced.

Description

The utility model is meant a kind of mould device, is meant a kind of continuous punch forming especially, just can be made into the continuously shaped die device of Western-style umbrella metal trough bone.

Mould manufactures and designs ability, be the symbol of precision component production capacity, in the high-tech product in modern times, will try to achieve especially strictly for the tolerance value of part, and be to satisfy machine parts'precise degree height and the big demand of output, develops mould industry, cooperate the development of various make-up machines, so the production of many precision components, except a high-accuracy machinery, the good precision die of a more bound cover cooperates just can be finished.

See also Fig. 1, Fig. 2 and shown in Figure 3, and the mode of production of present situation Western-style umbrella metal trough bone is to be divided into for three stages, just with three diels could moulding one Western-style umbrella metal trough bones 10 finished product, the original material that first mould will be put in order volume is cut, form blocks of Western-style umbrella metal trough aggregate sheet 11 as shown in Figure 1, be provided with predetermined perforation 111 simultaneously and in described tablet upper punch, then the more described tablet that cuts 11 is inserted in second mould, second mould is the mould of bending forming, just with described tablet 11 after the second mould punch forming, present U-shaped tablet 12 as shown in Figure 2, described U-shaped tablet 12 dashes and is provided with suitable vertically curved groove 121; At last described U-shaped tablet 12 is inserted in the 3rd mould, the 3rd mould is a pressing mold, and just with the two ends pressing in addition of described U font tablet, the two longitudinal edge ends that make described U font tablet are through pressing, and make as shown in Figure 3 closed shape 13, so just finished Western-style umbrella metal trough bone 10 finished products.Above-mentioned Western-style umbrella metal trough bone 10 production processes in the past have following shortcoming:

The manufacturing of a Western-style umbrella metal trough bone needs three secondary moulds, want three people of smooth and easy need to operate a part respectively as flow process, semi-finished product must be through repeatedly carrying, so whole cost in man-hour is oversize, and three people's wage, in today that the Taiwan wage grows to even greater heights, be to produce dealer's to bear greatly, although the technical level in Taiwan is higher, the value of product can be improved, but for the cheap labourer of general developing country, and the technical capability of growing up fast, the international community that present this incoherent mode of production is easy to be competed eliminates, and Taiwan industry is in the transitional period at present, and the whole people expect and the hierarchy of skill can be improved again, and can promote national production level, also just can become developed countries, should will take the long view, only not satisfy present situation at the moment for of short duration interests so produce the dealer.

Main purpose of the present utility model is the continuously shaped die device that is to provide a kind of Western-style umbrella metal trough bone, described mould is with friction feeding, continuous stamping forming mode, material is sent in the mould, after the impact molding machine moulding, being taken out by impact molding machine is exactly the Western-style umbrella metal trough bone finished product of finishing, and has both saved manpower and has made speeding up of production.
