Embodiment 1

[0048] Such as figure 2 As shown, in this embodiment, the functional body is an elastic body, and the elastic body is used to push up the concave ring in the middle of the stainless steel pressing pipe fitting to a pipe body having the same diameter as the connecting pipes on both sides. The invention adopts the elastic body for jack-up processing, which can ensure the molding quality without damaging the inner wall of the pipe fitting, and the middle part of the formed pipe body fully fits the pipe body forming cavity, and there is no need for secondary shaping operations in the later stage.

[0049] The cross-sectional diameter of the spacer positioning cavity is larger than the cross-sectional diameter of the pipe body forming cavity; the axial section of the top-mounted spacer is "T"-shaped, and the top-mounted spacer is inserted into the right end of the stainless steel clamping pipe. The small-diameter end, the right-end annular protrusion of the stainless steel clampin...

Embodiment 2

[0056] This embodiment is the quality inspection steps after processing the stainless steel double clamping adjustable straight head in the first embodiment. The horizontal punching pin is cylindrical, and its outer diameter is the same as the inner diameter of the middle section after the stainless steel clamping pipe is processed into an adjustable straight head; the outer wall of the horizontal punching pin is smooth without scratches.

[0057] The quality inspection process of the stainless steel double-press adjustable straight joint includes the following steps:

[0058] After completing the step (2) in the production process of the stainless steel double clamping adjustable straight head, the elastic body is removed from the horizontal punching pin, and then the horizontal punching pin driving device drives the horizontal punching pin to insert into the stainless steel clamping pipe and then pull it out. Observe whether there are scratches on the outer surface of the ho...

Embodiment 3

[0062] Such as Figure 5 As shown, in this embodiment, on the basis of retaining the structure of the upper molding die and the lower molding die described in Embodiment 1, a vertical punching hole is opened on the upper molding die. vertical punching pins are arranged in the vertical punching holes, and the vertical punching pin driving device is connected above the vertical punching pins.

[0063] A spacer extension block is installed at the small diameter end of the top-mounted spacer block, and a spacer slot is provided at the bottom of the spacer extension block.

[0064] The production process of the stainless steel double clamping adjustable tee joint includes the following steps:

[0065] (1) Separate the molding upper mold and the lower molding mold; install the pad extension block on the small diameter end of the top mounting pad, insert the small diameter end of the top mounting pad block and the pad extension block on the right end of the stainless steel compressi...

Abstract

The utility model discloses a stainless steel double-clamping-pressure adjustable direct joint and tee joint production die, and belongs to the technical field of stainless steel pipe fitting machining. The die is characterized in that an upper forming cavity and a lower forming cavity are formed on the opposite working faces of an upper forming die and a lower forming die respectively; the rightend of the upper forming cavity is connected with an upper cushion block positioning containing cavity, and the right end of the lower forming cavity is connected with a lower cushion block positioning containing cavity; after the upper forming mold and the lower forming mold are buckled, the upper forming cavity and the lower forming cavity are enclosed to form a pipe body forming cavity, and theupper cushion block positioning accommodating cavity and the lower cushion block positioning accommodating cavity are enclosed to form a cylindrical cushion block positioning accommodating cavity; the end, close to the pipe body forming cavity, of a transverse punching needle is connected with a functional body, and the end, far away from the pipe body forming cavity, of the transverse punching needle is connected with a transverse punching needle driving device, and the transverse punching needle, the functional body, the pipe body forming cavity and the cushion block positioning containingcavity are coaxially arranged. The adjustable double-clamping-pressure adjustable straight joint and tee joint production die can achieve two purposes for producing and manufacturing the stainless steel double-clamping-pressure adjustable direct or adjustable three-way joints of various different specifications.

Description

technical field [0001] The invention belongs to the technical field of processing stainless steel pipe fittings, and in particular relates to a production mold for a stainless steel double clamping adjustable straight joint and a three-way joint. Background technique [0002] Utilizing the effective rigidity of the metal material and the elastic compression ratio of the sealing material, and making full use of the length of the socket, the pipeline method that is crimped and connected with clamps on both sides of the U-shaped groove of the pipe socket is called a double clamping type. The double clamping piping system is one of the most reasonable, safest and reliable connection methods among domestic thin-walled metal pipe connection methods. [0003] At present, stainless steel pipes have begun to be widely used in many systems such as direct drinking water, tap water, hot and cold water, heating, gas, fire sprinklers, etc. Among them, double-press stainless steel pipe fit...
