Extrusion molding equipment for a non-flared conduit connector

Abstract

The invention discloses an extruding molding equipment for a non-flared conduit connector. Including cabinet, hydraulic system, clamping mechanism, stretching mechanism, operation panel, working platform; hydraulic system provides power for clamping mechanism and stretching mechanism; stretching mechanism includes stretching drive mechanism and bulging mechanism, and bulging mechanism includes The center is located on the same axis as the adapter, the anvil, the half female mold and the tie rod assembly; the anvil mold has a four-stage diameter cylindrical cavity structure arranged in sequence; the half female mold is a symmetrical structure formed by combining two semicircular rings and It can be detachably installed in the clamping arm of the clamping mechanism. When the two half rings are combined, a mold clamping gap is formed at the joint. The device of the present invention can effectively reduce the labor intensity of the operator, and can adaptively clamp the individual size differences of different workpieces of the same theoretical specification, and can realize direct closed-loop extrusion force control, thereby improving the quality of the produced products , to solve the problem of troublesome mold replacement and the need for many tools to disassemble.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and manufacture, in particular to the technical field of extrusion molding processing machinery design and manufacture, and in particular to an extrusion molding equipment for a non-flared conduit connector. Background technique [0002] In the prior art, the connection of the catheter connector is usually made by sealing a compressible elastic material with a certain volume, such as polyurethane material, in the processing space, and after extruding it to an incompressible stage, the catheter is deformed by polyurethane Partial extrusion produces plastic deformation, and the plastic deformation is extruded into the inner ring groove of the guide sleeve on the catheter, so that the catheter and the guide sleeve are tightly connected. [0003] The above method is widely used for plastic processing and connection of non-flared conduits, and this processing method is adopted in the Chinese ...

Problems solved by technology

In the specific implementation of this method, there are obvious defects: First, the clamp mechanism needs to manually operate the mechanical mold clamping during operation, and then drive the automatic mold clamping through the cylinder, which brings a great workload to the operators , this structure only realizes automatic mold clamping after mold clamping; secondly, in this mold clamping mode, the upper and lower clamps rely on their upper and lower mating surfaces to uniquely determine the mold clamping position, so the positions of the upper and lower clamps are always the same, In fact, different individual workpieces of the same theoretical specification will have differences in structural dimensions, and their outer diameters may be large or small, which will lead to some processing problems, such as interfering molds affecting mold clamping and causing products to be pinched , or the clamp is not tight, so that there is a gap between the workpiece and the cavity in the half-clamp mold located in the clamp, which cannot play a supporting role, so that during processing, the tube sleeve in the workpiece combination is squeezed under the internal expansion force of polyurethane Third, in the process of extruding polyurethane to realize conduit connection, the control of extrusion force is open. In fact, there will always be differences in structural dimensions between different workpieces. Polyurethane materials are used A certain number of times needs to be replaced, so each replaced individual has a difference in structural size and density, which means that for each specific processing catheter workpiece, the amount of compression and the movement stroke that needs to be squeezed are different. Usually The method is to use the pressure of the hydraulic system as the control quantity to realize the compensation for this difference. It is realized by setting a pressure sensor on the oil circuit of the hydraulic system to feed back to the system. Pressure, whose control is not direct and precise enough
