CS245284B1 - high-frequency welding of products made of thermoplastic materials - Google Patents

Abstract

The press for high-frequency welding of thermoplastic parts is intended primarily for the leather industry of light industry. The press can be used in the production of footwear, for welding car seat covers, in the printing industry, in the production of toys. The purpose of the solution is to expand technological possibilities, improve product quality, increase the performance and reliability of the fuhkoe press. The press is equipped with adjustment tables mounted on the press stand, on which the lower welding plates and devices for their horizontal displacement into the working space of the press are placed, a cross beam connected to the stand by columns and carrying the upper welding plate and the central column, a device for regulating the gap between the welding plates provided with nuts kinematically connected to the drive, a drive for the vertical working stroke of the lower welding plates, a power line for supplying high-frequency current, a shielding device with a mechanism for its displacement, a device for automatic fine-tuning of the high-frequency generator and a control circuit for controlling the function of the press. The essence of the solution lies in the fact that the press is provided with a unit /39/ for automatic selection of the required height of the gap between the welding plates /6, 7 and 16/, a common grounded contact /18/ fixed in the upper part of the central column /15/ and technological contacts /19, 20/ placed on the beam /1/, the number of which corresponds to the number of the positioning tables /4, 5/ and to which are assigned mechanisms /23, 24/ for their vertical displacement and indicators /25, 26/ of the height of the gap between the welding plates /6, 7 and 16/, while the nuts /29, 30/ of the device for the relation of the gap between the welding plates , 7 and 16/ are placed on the central column /15/, which has a screw peripheral surface, and are spring-loaded relative to each other and relative to the beam /1/, while the upper welding plate /16/ is fixed at the lower end of the central column /15/ and the drive of the device for regulating the gap between the welding plates /6, 7 and 16/ is placed on the beam /1/.
