Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding device for a PEEK sealing ring. Background Technology

[0002] With the development of modern industry, the performance requirements for materials are becoming increasingly stringent. Specialty engineering plastics, due to their excellent mechanical properties, chemical stability, and high-temperature resistance, are widely used in many fields such as aerospace, automotive manufacturing, and medical devices. Welding PEEK sealing rings is a crucial technical step. For large sealing rings, when injection molding and compression molding are not cost-effective, welding becomes a more economical and faster method. However, because PEEK has a high melting point (approximately 340℃) and is temperature-sensitive, traditional welding methods such as ultrasonic welding and laser welding may not meet specific process requirements in certain situations. Furthermore, traditional welding methods are not suitable for welding products of different specifications.

[0003] Therefore, it is necessary to design a welding device for PEEK sealing rings to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a welding device for PEEK sealing rings.

[0005] The technical solution of this utility model is: a welding device for PEEK sealing rings, including a base and clamping mechanisms at both ends of the base; a heating mechanism is movably provided between the clamping mechanisms; the heating mechanism is used to heat the products clamped by the clamping mechanisms at both ends of the base; when the products clamped on the clamping mechanisms at both ends of the base are heated, the heating mechanism moves away, and the clamping mechanisms at both ends of the base move closer to weld the products on them.

[0006] The clamping mechanism includes clamping seats symmetrically arranged on both sides of the base and a first driving component for driving the clamping seats to move; a lower clamping plate is slidably connected to the top of the base along the length direction of the base; the end of the product is clamped on the clamping seat through the cooperation of the upper clamping plate and the lower clamping plate.

[0007] The heating mechanism includes heating blocks symmetrically and movable on both sides of the center of the base, and a second driving component for driving the heating blocks to move.

[0008] Both the clamping seat and the first driving assembly can be adjusted along the length of the base; the base is provided with an adjustment groove along the width direction corresponding to the clamping seat and the first driving assembly; the clamping seat and the first driving assembly are locked in the adjustment groove by bolts.

[0009] The first drive component is a cylinder.

[0010] The second drive component is a cylinder.

[0011] A welding apparatus for a PEEK sealing ring further includes a temperature measuring system; the temperature measuring system includes a PLC controller and an infrared thermometer for detecting the temperature of the heating mechanism; the PLC controller is electrically connected to both the heating mechanism and the infrared thermometer.

[0012] The above technical solution has the following beneficial effects: (1) The present invention achieves an automated welding process of heating-removing-pressing through the coordinated cooperation of the double-end clamping mechanism and the movable heating mechanism, which greatly improves the welding efficiency. The design of quickly removing the heating mechanism and pressing after heating can avoid heat source interference in the welding process and ensure the joint quality.

[0013] (2) This utility model adopts the structure of upper and lower clamping plates and clamping seats. Combined with adjustable clamping seats and drive components, it can adapt to sealing rings of different sizes and has stronger applicability.

[0014] (3) This utility model uses PLC and infrared thermometer to precisely control the temperature, ensuring that the welding temperature is within the qualified range, thereby guaranteeing the welding quality. Attached Figure Description
