Abstract
The utility model relates to a condenser tube die, in particular to a one-step squeezing die for condenser tubes. The one-step squeezing die comprises an upper die (1), a lower die (2) and die plates (3), the lower part of the upper die (1) is inserted in the lower die (2), the die plates (3) are arranged between spiral rings, and the cavity of the lower die (2) is a spiral ring die cavity (4). The utility model has the advantages of low cost, little investment, feasible technique, reliability, high product quality, one-step squeeze forming and high yield.
Description
Technical field
The utility model relates to the condenser pipe mould, is specially a kind of condenser pipe one-step method extrusion die.
Background technology
Condensed type combustion gas water heater is as the high-tech new product of a kind of environmental protection and energy saving, market prospects are wide, in order to realize the condensation method of operation, must behind the high temperature section heat exchanger of conventional (non-condensing) water heater, increase the condensation segment heat exchanger, and the condensation segment heat exchanger is because the complex structure manufacture difficulty is big, the cost height has restricted condensing type water heater popularizing and development in China.Condenser pipe is the vital part in the family expenses condensed type combustion gas water heater because its planform more complicated, by the flat wound pipe that 4.25 circles are formed, two ends be Cylinder transition is connected with taper, enclosing on the plane of flat tubes 4 respectively has 9 convex closures.Domestic have producer to adopt conventional method to develop the not success as yet of 2 years as many as the presents.
Summary of the invention
The utility model is just at above problem, provides that a kind of low cost, feasible process, mould are reliable, good product quality, investment is little, output is high condenser pipe one-step method extrusion die.
The technical solution of the utility model is as follows:
Condenser pipe one-step method extrusion die is made up of upper die and lower die, matrix, and the bottom of patrix is linked in the counterdie, and matrix is arranged between the spiral coil spare, and following mold cavity is a spiral coil spare die cavity.
To roll up curved garden spiral casing pack of getting well when using the utility model directly through being the shot of 0.3～1.0mm, the difformity of packing between bung flange more also is provided with recessed poor matrix for extruding 36 convex closures.Then with in its whole spiral coil spare die cavity 4 of packing into, when patrix pressed down, tube outer wall compressive deformation, inwall were subjected to shot to extrude 36 convex closures and all moulding to reach and give provisioning request.
Good effect of the present utility model shows:
1, low-cost, investment is little.
2, feasible process, reliable, the good product quality of mould.
3, the utility model one-step method extrusion modling, the output height.
4, the utility model reduces manufacturing cost, has played certain impetus for cultivating condensed type combustion gas water heater demand market.

The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment and Figure of description.
Specific embodiment:
Condenser pipe one-step method extrusion die is made up of patrix 1, counterdie 2, matrix 3, and the bottom of patrix 1 is linked in the counterdie 2, and matrix 3 is arranged between the spiral coil spare, and counterdie 2 inner chambers are spiral coil spare die cavity 4.
To roll up curved garden spiral casing pack of getting well when using the utility model directly through being the shot of 0.3～1.0mm, the difformity of packing between bung flange more also is provided with recessed poor matrix for extruding 36 convex closures.Then with in its whole spiral coil spare die cavity 4 of packing into, when patrix pressed down, tube outer wall compressive deformation, inwall were subjected to shot to extrude 36 convex closures and all moulding to reach and give provisioning request.
