Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to an integrated machine for marking bulges on pipe fittings. Background Technology

[0002] In the field of pipe fitting processing technology, bulging refers to an annular radial protrusion formed on the pipe wall by extrusion; dotting refers to radial dot-like depressions formed on the pipe wall by extrusion. Bulging and dotting of pipe fittings are very common in large-scale mass production.

[0003] Chinese Patent Publication No. CN104690127B discloses a device and method for processing bulges on pipe fittings. It includes a mold base consisting of an upper mold base and a lower mold base pressed together by a pressing device. The mold base has a receiving cavity for accommodating the pipe fitting, and two annular grooves are axially spaced within the receiving cavity. Two sets of extrusion components with identical structures and opposite directions of movement are slidably fitted within the receiving cavity for simultaneously forming two bulges on the pipe fitting. This provides a device and method for processing bulges on pipe fittings that can simultaneously process two bulges and has a simple mold base structure. However, the aforementioned device and method for processing bulges on pipe fittings have several drawbacks: the inability to perform a dotting process; the need for manual loading of the pipe fitting, resulting in low efficiency and potential for inaccurate positioning and unstable installation; and the requirement for manual opening of the mold base after bulge processing, as automatic unloading is not possible. Utility Model Content

[0004] To address this issue, this utility model provides an integrated machine for marking and bulging pipe fittings, which overcomes the problems of low efficiency and error-proneness caused by the separation of the bulging and marking processes in the prior art, requiring manual feeding, process changes, and unloading.

[0005] To achieve the above objectives, this utility model provides an integrated machine for marking bulges in pipe fittings, comprising:

[0006] The feeding mechanism includes a horizontal limiting component for constraining the horizontal position of the original pipe fitting and a displacement component partially disposed above the horizontal limiting component for conveying the original pipe fitting to the target bulge marking position.

[0007] The bulging mechanism, which is partially located below the feeding mechanism, is used to bulge the original tube to output a bulged tube. It includes a bulging generating component for forming the bulge and a bulging power component connected to the bulging generating component for providing extrusion power and unloading power.

[0008] The dotting mechanism is arranged perpendicularly to the bulging mechanism on a horizontal plane. It includes a pair of dotting components symmetrically arranged on both sides of the bulging generating component, which cooperate with each other to symmetrically dot the bulging tube to output the finished tube.

[0009] Furthermore, the horizontal limiting component includes:

[0010] Pipe-passing platform, used to constrain the spatial position of the original pipe fittings before they enter the placement platform;

[0011] A placement platform, located at the output end of the pipe-passing platform, is used to horizontally place the original pipe fitting;

[0012] The placement platform is provided with a U-shaped correction groove that runs through the placement platform to constrain the position and angle of the original pipe relative to the displacement component; wherein, a pair of cuboid-shaped clearance grooves connected to the correction groove are provided on both sides of the correction groove, the horizontal distance between the clearance grooves is less than the diameter of the correction groove, and the depth of the clearance grooves is greater than the depth of the correction groove, so as to avoid the displacement component.

[0025] Furthermore, the front mold includes: a slide connecting plate, a first mold base connecting plate, a second mold base connecting plate, a third mold base connecting plate, a front mold base, a front mold core, a front rod core, and an extrusion sleeve;

The rear mold base fixing plate is connected to the bulging platform to fix the position of the rear mold base. The rear rod core is inserted into the rear mold base and the rear mold core, and its front end has a conical structure with a bottom diameter smaller than the diameter of the rear rod core, forming an end face with the same wall thickness as the original pipe fitting, so that the end face can apply pressure to the end face of the original pipe fitting during the bulging process.

[0032] Furthermore, for a single dotting assembly, it includes: a punch, a punch sleeve, a punch limiting tube, a fixing block, and a dotting power cylinder;

[0033] The punch sleeve is mounted on the side of the drum-shaped platform via the fixing block.

[0035] Furthermore, the front end of the front rod core is a conical structure, and the front end of the conical structure is provided with an end face to avoid the rear rod core; a pair of keyways are provided on both sides of the conical structure corresponding to the position of the punch to avoid the punch.

[0036] Furthermore, the bulging power assembly includes a bulging power cylinder and a unloading power cylinder; the bulging power cylinder is connected to the bulging slide table and is used to drive the bulging generation assembly to perform bulging operation on the original pipe fitting; the unloading power cylinder is connected to the rear core and the rear core receiving sleeve and is used to push the finished pipe fitting away from the rear mold after the front mold and the rear mold are separated.

[0037] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a feeding mechanism including a horizontal limiting component and a displacement component, the horizontal limiting component pre-constrains the position and angle of the input raw pipe, reducing the displacement direction required by the displacement component and improving the feeding efficiency and feeding accuracy of the device; by setting up a bulging mechanism and a dotting mechanism that cooperate with each other, the bulging and dotting processes are combined, thereby improving the working efficiency of the device and the product qualification rate.

[0038] Furthermore, the bulging mechanism of this utility model forms a bulge by extruding the original tube fitted on the front rod core inside the mold at both ends through the extrusion sleeve and the rear mold core. This breaks through the traditional bulging method of extruding soft inner cores, eliminating the need to repeatedly replace the inner core and manually demold, thereby reducing costs and improving the working efficiency of the device.

[0039] Furthermore, the bulge generation component of this utility model, by setting a first mold base connecting plate, a second mold base connecting plate, a third mold base connecting plate, a rear mold base fixing plate, and a rear core receiving sleeve, makes the front core, extrusion sleeve, and rear core easy to replace, so as to process original pipes of different lengths and wall thicknesses, thereby improving the applicability of the device.

[0040] Furthermore, the bulging power assembly of this utility model, by setting a discharge power cylinder, pushes the finished pipe to demold after the mold is separated, thereby realizing automatic discharge and improving the working efficiency of the device.

[0041] Furthermore, the front core of this utility model avoids the punch by setting a conical structure and a pair of keyways on both sides of the conical structure, so that the device can start the dotting process immediately after the bulging operation without moving the bulging tube, thereby improving the working efficiency of the device.
