Abstract
The invention relates to a mold for manufacturing an outer ring body used in gimbal and a method thereof. The mold is mainly composed of a female mold and a male mold which are matched with each other. The female mold is internally provided with a female mold chain used for holding a product. A die cavity which is internally arranged in the female mold chain and used for holding the product is provided with the male mold. The die cavity is also provided with an ejector which presses downwards. The method is as follows: proper bar material is selected to be processed for baiting and cold forging into a cake-shaped roughcast; heat treatment is applied to the roughcast and then the surface treatment; after that, the roughcast is put into the die cavity of the female mold chain and arranged above the male mold and is extruded downwards by the ejector to be molded; after being demoulded, the roughcast is made into a finished product by machine processing. The mold can reduce energy consumption, improve product precision, save manpower, lift the operating factor of raw material, simplify the structure of the mold, cut the expense of the mold, and lower manufacturing cost, while facilitating installation and adjustment of the mold, thus being good for mass diversified production, etc.
Description
Technical field
What the present invention relates to is mfg. moulding die and the cold squeezing production method of a kind of universal joint with outer ring body, belongs to the compression molding technology field.
Background technology
Universal joint is a kind of frame for movement that is widely used in the machine industry, and aircraft in the sky, automobile on the ground all be unable to do without it.In any machine driving, all might use it, its function be should bearing torque transmission, adjust the direction of power again at any time.Because the universal joint product purpose is wide, market is big, must cause both at home and abroad the aggravation of competition mutually, therefore improves the quality of products, and reduces cost, and becomes everybody main target in competition.What the outer ring body that present domestic production universal joint is used adopted is the hot extrusion technique technology, and it is under the condition of heating blank, to the blank extrusion modling.This hot extrusion technique not only will consume a large amount of energy, and the precision of product is subjected to the influence of rising-heat contracting-cold easily, and raw-material utilization rate is low, can exert an influence to environment.In other application, adopted a kind of cold extrusion process for machining and manufacturing for some thin wall shapes, less demanding blank product, the instructions for use of this technology is higher relatively, be applicable to production in enormous quantities, but the key that adopts cold-extrusion technology is the design and the manufacturing of cold extrusion die, and therefore existing cold extruding technique can not be transplanted simply in the manufacturing processing of universal joint of the present invention with outer ring body.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and a kind of in enormous quantities, many variety production that can help are provided, the energy energy savings reduces manufacturing cost, improves mfg. moulding die and the method for the universal joint of utilization rate of raw materials with outer ring body.The objective of the invention is to finish by following technical solution, it mainly is to be made of die and the punch of arranging that complement one another, described die intermediate configurations has the die iron chains spare of inserting for product spare, dispose punch in the die cavity of inserting for product spare that is provided with in the middle of this die iron chains spare, and in this die cavity, also dispose downward roof pressure and get ejector.
Described die is placed on the positioning piece, and the circumferential arrangement of punch has an inloading part device.
The cold extrusion manufacturing processing method of utilizing above-mentioned universal joint with the mfg. moulding die of outer ring body of the present invention, it is to select suitable bar for use, become the patty blank through blanking and cold pier, after blank heat-treated, carry out surface treatment again, put into the die cavity of die iron chains spare then, be placed in the die top, by the downward extrusion modling of ejector, after the demoulding, make finished product through Vehicle Processing again.
Described heat treatment mainly takes to carry out rough annealing in vertical heater, eliminate internal stress, improves internal organizational structure; Affiliated surface treatment comprises pickling descale, clear water rinsing, immersion lubrication fat.
The present invention compares with existing hot extrusion forming technology, has energy savings consumption, improves the product precision, save the manpower consumption, improved characteristics such as raw-material utilization rate, environmental protection, cleaner production promotes product quality, and positive role is played in the realization sustainable development; Compare with existing cold extruding technique, simplified mould structure, dwindled the size of mould up and down, thereby saved die cost, reduced manufacturing cost, and made things convenient for the installation and the adjustment of mould, help characteristics such as in enormous quantities, many variety production.
Description of drawings
Fig. 1 is a mould structure schematic diagram of the present invention.
The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in the accompanying drawing 1, the universal joint of the present invention mfg. moulding die of outer ring body, it mainly is to be made of die 1 and the punch of arranging 2 that complement one another, they can be arranged to upper die and lower die respectively, die 1 shown in the accompanying drawing is a patrix, and punch 2 is a counterdie.Described die 1 intermediate configurations has the die iron chains spare 3 of inserting for product spare, disposes punch 2 in the die cavity 5 that supplies product spare 4 to insert that is provided with in the middle of this die iron chains spare 3, and also dispose the ejector 6 of downward roof pressure in this die cavity 5.Die 1 shown in the figure is placed on the positioning piece 7, and the circumferential arrangement of punch 2 has an inloading part device 8.
Die of the present invention and punch are two major parts of decision product quality, simultaneously also be two major parts that solve die life, so described die adopts iron chains spare structure, wherein iron chains spare and punch have adopted the extraordinary mould steel manufacturing of steel construction carbide alloy.
The cold extrusion manufacturing processing method of utilizing above-mentioned universal joint with the mfg. moulding die of outer ring body of the present invention, it is to select suitable bar for use, become the patty blank through blanking and cold pier, after blank heat-treated, carry out surface treatment again, put into the die cavity of die iron chains spare then, be placed in the die top, by the downward extrusion modling of ejector, after the demoulding, make finished product through Vehicle Processing again.
Described heat treatment mainly takes to carry out rough annealing in vertical heater, eliminate the internal stress of front operation, improves internal organizational structure, strengthens the flowability of metal in the cold extrusion process; Described surface treatment, be for the cold extrusion requirements of one's work, blank also comprises pickling descale, clear water rinsing, immersion lubrication fat after heat treatment, its effect be reduce raw material in extrusion process with the coefficient of friction of die surface, thereby realize raw-materially smooth and easyly flowing and reducing the rate of wear to die surface.
Extrusion blank of the present invention and machine-shaping are the physical dimensions according to product, according to the principle of constancy of volume before and after the cold extrusion, calculate and select suitable bar for use, become the patty blank through blanking with cold pier.
