Problems solved by technology

[0003] The trimming methods of rubber products generally include manual trimming, mechanical trimming and freezing trimming. Since rubber products are mostly produced in batches and have low hardness, the methods of manual trimming and mechanical trimming cannot be effectively applied to Rubber products require large quantities, high efficiency and high quality, so the method of freezing and trimming is widely used
[0004] In the freeze trimming process, in order to improve the trimming quality and trimming efficiency, shot blasting with a mixture of several particle sizes will be used for trimming work, but in the high-speed spraying process of shot peening, due to the mixing Spraying out will easily cause the blockage of the nozzle and the jamming of the injection, which will not only affect the trimming quality of rubber products, but also easily cause damage to the freezing trimming machine

Embodiment 1

[0048] see Figure 1-10 , an efficient freezing trimming process for rubber products, comprising the following steps:

[0049] S1. Preset parameters, according to the precision requirements of rubber products, basic setting of the working parameters of the frozen trimmer 1;

[0050] S2. Feeding, putting the rubber product into the trimming cylinder, and closing the hatch of the refrigerated trimmer 1, so that the refrigerated trimmer 1 freezes the rubber product;

[0051] S3. Shot peening and trimming, after the cooling in the freezer trimming machine 1 is completed, the trimming nozzle 2 is started, and the shot peening will be sprayed toward the trimming cylinder, and the trimming cylinder is in a synchronous rotation state at this time;

[0052] S4. Swing jet, in the process of continuous shot peening, if the pressure in the shearing direction of the swing nozzle 4 increases, the pressure sensing beads 6 transmit the shear pressure of the swing nozzle 4, so that the heat i...

Abstract

The invention discloses an efficient freezing and trimming process for a rubber product, and belongs to the field of rubber product manufacturing, and the efficient freezing and trimming process for the rubber product comprises the steps that parameters are preset; feeding the materials; shot blasting and trimming; swinging spraying: in the continuous shot blasting spraying process, if the pressure in the shearing direction in the swinging spraying pipe is increased, the pressure sensing bead transmits the shearing pressure of the swinging spraying pipe; through cooperation of a pressure swing sleeve, a pressure induction bead, a thermal triggering swing arc block and a swing spray pipe, when blockage or jamming omen occur in the shot blasting process of the trimming spray head, dynamic change of the shot blasting pressure in the swing spray pipe can be effectively achieved, and the shot blasting efficiency is improved while the spraying strength and direction are effectively kept. The probability that the trimming nozzle is blocked and blocked is effectively reduced, then the trimming quality of the rubber product is effectively improved, mechanical damage of the freezing trimming machine is reduced, and development of freezing trimming of the rubber product is promoted.

Description

technical field [0001] The invention relates to the field of rubber product manufacturing, and more particularly, to a high-efficiency freezing trimming process for rubber products. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. The manufacturing process of rubber is based on basic processes such as plasticizing, mixing, calendering or extrusion, molding and vulcanization. Each process has different requirements for the product, and some auxiliary operate. In the process of rubber molding, due to the factors of production process or equipment, there will be overflow of glue - that is, flashing. In order to maintain the appearance of rubber products in a regular, beautiful and high quality, it is necessary to trim plastic products. [0003] The trimming methods of rubber products generally include manual trimming, mechanical trimming and freezing trimming. Since most of the rubber products are mass-produced and h...
