The equipment mainly comprises an upper mold, a lower mold, a positioning ring and the like, and is characterized in that the upper mold and the lower mold are thread molds fitting each other; and a cylinder is disposed between the upper mold and the lower mold. The production process comprises the following steps: firstly, the metal circular cylinder is expanded to form a step shape with a small opening and a large middle portion according to the material deformation characteristic; then, the opening step is shaped to make a segment of a straight edge; and finally, the shaped segment of the straight edgeis externally and internally extruded by using equipment and a mold of the rolled threads, is processed to the shape of threads, and is cut and finished. The production process and the equipment have the following advantages: a thread rolling process is adopted, so that the centering is easy in connection fitting of two iron shell threads, the connecting firmness is more reliable, and the problem that conventional two cylinders are prone to eccentric dislocation in connection is solved; and meanwhile, a plastic part in middle transitional connection is not needed, so that the assembly is convenient, the manpower is saved, and the cost is saved.
Description
Technical field
The present invention relates to a kind of manufacture method and equipment of cool-bag, particularly a kind of manufacture craft of cool-bag stack shell rolled thread and equipment.
Background technology
Shell and the stack shell of general cool-bag have polytype, and what mainly say here is the shaping technology type of stack shell oral area rolled thread.When along with the raising of people's living standard and the cosmetic requirements of industrial progress to the shell of cool-bag more and more higher, traditional structure is that centre adds plastic part transition connection type, this will easily cause upper and lower two iron-clad parts to produce dislocation, affect the overall aesthetic of outward appearance, increase plastics transition union piece and also make cost correspondingly increase.One. due to the restriction of instrument and supplies, in order to ensure the connection of upper and lower two stack shells, traditional method is the technique that upper and lower two stack shell opening parts use circle round edge, and respective inside has filled the eyebolt of plastics, middle again with being with the plastic part of thread to make to connect both it.This connected mode is relatively difficult when assembling, and because the change in size of the plastic components connected is comparatively large, is difficult to control to good dimensional accuracy, and therefore upper and lower two stack shells screw the dislocation of rear easy appearance bias, and outward appearance is difficult to reach requirement.Two. if upper and lower two stack shells have one to have one with plastics with iron-clad, then outer surface does not totally reach the effect of metal material, have impact on the overall appearance of metal thermal insulation container stack shell yet.
Summary of the invention
The object of the invention is the defect for existing in prior art, in order to change the syndeton of traditional canister metals stack shell, solving the connectivity problem of metal stack shell, the invention provides a kind of manufacture craft of cool-bag stack shell rolled thread.Equipment comprises: upper die and lower die, centring ring, baffle plate, rotating shaft, lower mould holder, fixing fuse, it is characterized in that one end of described rotating shaft is provided with baffle plate, patrix is screw-shaped, patrix is arranged in the rotating shaft outside baffle plate, the top of rotating shaft is provided with fixing fuse, stack shell is sleeved on patrix and fixing fuse, the centring ring compressing stack shell is provided with outside stack shell, counterdie is arranged on lower mould holder, counterdie and stack shell outer wall offset, patrix and stack shell inwall offset, and patrix is the threaded mold coordinated each other with counterdie, and rotating shaft is driven by equipment dynamic.
Technique of the present invention comprises the following steps successively:
(1) bulging, becomes the little step shape broad in the middle of opening by metal cylinder one end bulging of circle;
(2) shaping, carries out shaping to the step of the circular metal stack shell opening through step (1) bulging, makes one section of straight section;
(3) rolled thread: the rolled thread mode adopting face contact, orthopedic stack shell is sleeved on mould by step (A), by fixing fuse, centring ring by stack shell stationary positioned; (B) the upper and lower mould of screw-shaped is in place; (C) rotating shaft of rolled thread device drives and screw-shaped patrix, stack shell is driven to rotate together, the straight section of stack shell body opening is clipped in the rotation of engaging between the upper and lower mould of screw-shaped, and carries out inside and outside extruding to the straight section of stack shell opening, makes the straight section of stack shell opening roll out screw thread;
(4) subsequent forming and surface treatment is entered after being cut by length dimension requirement by the stack shell of good for roll extrusion screw thread.
Above-mentioned steps (3) stack shell material thickness is: t=0.55 ~ 0.65mm, and the depth of thread is 0.8 ~ 1.2mm, and thread segment shape is circular arc, and the pitch of stack shell screw thread is identical with the pitch of mould, M1=M0.
Advantage of the present invention adopts rolled thread technique, this technique can make metal cylinder stature material produce plastic deformation, extrude thread shape, ensure height and the cross sectional shape of screw thread, the rigidity intensity increase of material is made to be not easy distortion, the mistake circularity of product is reduced as much as possible, product size is more stable, this process is easy to operate, ensure that product quality, be easy to realization work continuously, especially be suitable for promoting in production in enormous quantities, use the successful Application of this technique can be used widely for subsequent development new product of the same type, use this technique that product is easily centered when two iron-clads are threaded and coordinate, connect fastness more reliable, easily there is the problem of eccentric dislocation in the connection solving original two stack shells, the plastic part that a middle transition connects can be reduced simultaneously, both saving manpower convenient for assembly again saved cost, improve the quality of product.
