Description

Novel clamp

Technical Field

The invention relates to a screw rod disassembling machine assembly, in particular to a novel clamp applied to a screw rod disassembling machine.

Background

The screw extruder is the equipment commonly used in the plastics processing procedure, and the screw rod on the screw extruder of current, most are by the dabber and cup joint the screw thread subassembly on the dabber and constitute, and the screw thread subassembly can be changed according to actual production needs. However, it is time consuming and laborious for the plastics processor to replace the screw assembly on the screw during the production process.

In general, replacing the screw assembly requires disassembling the original screw assembly from the screw rod, and then replacing and assembling the screw assembly. However, since the screw is often subjected to high temperatures and pressures in the barrel, liquid plastic is squeezed between the screw thread component and the mandrel, and carbides are generated therein, resulting in the screw thread component and the screw mandrel being firmly bonded together, sometimes even causing extrusion deformation. Therefore, it is not easy to disassemble the screw assembly. For a long time, people generally adopt a manual beating mode when disassembling the screw rod, the one-hammer one-way beating mode often causes great impact on the thread block, the thread component is often broken, various scrapping phenomena are caused, and the equipment maintenance cost is increased; meanwhile, the manual beating mode requires a worker to perform long-time high-intensity labor, and is low in efficiency and very inconvenient.

Through elaborate research, the applicant invents a machine capable of conveniently and quickly disassembling the screw rod. In order to ensure the smooth detachment of the threaded component, the clamp must be prevented from rotating and slipping when clamping the threaded component, and in order to improve the application range of the screw disassembling machine, the screw disassembling machine preferably has the functions of forwardly disassembling the screw and reversely disassembling the screw.
