Two-row chain pre-pull and joint dismantling device

Abstract

The invention discloses a two-row chain pre-pull and joint dismantling device, which comprises a pre-pull mechanism and a joint dismantling mechanism. A chain stacking plate is arranged between the pre-pull mechanism and the joint dismantling mechanism, the joint dismantling mechanism comprises a working table, a joint dismantling module is arranged on the working table, a chain engaging-in channel and a chain engaging-out channel are arranged at the two ends of the joint dismantling module correspondingly, a driving sprocket wheel is arranged at the chain engaging-in channel, the driving sprocket wheel is connected with a servo motor through a planetary reducer, and a laser marking machine is arranged on the position, on one side of the chain engaging-in channel, of the working table. Thetwo-row chain pre-pull and joint dismantling device has the advantages of realizing pre-pull and joint dismantling continuous processing of a double-row chain, high operation stability, long servicelife of the device, good quality of processed products and environmental protection.

Description

technical field [0001] The invention relates to the field of production equipment for double-row chains, in particular to a double-row chain pre-drawing and dismantling device. Background technique [0002] At present, there are few equipments on the market designed for the two processes of dynamic pre-stretching and joint dismantling of double-row chains. In terms of joints, it is more difficult to disassemble the double-row chain than the single-row chain. The single-row chain only needs to flush out the pin shaft until the outer chain plate comes out, while the double-row chain needs to completely flush out the pin shaft, and the design pushes Push the upper and lower outer chain plates and the middle chain plate. Due to the difficulty of dismantling the joints of the double-row chain, manual dismantling is generally used at present. The knocking force and position of the manual dismantling are different, and the labor intensity of the workers is high and time-consuming. ...

[0002] At present, there are few equipments on the market designed for the two processes of dynamic pre-stretching and joint dismantling of double-row chains. In terms of joints, it is more difficult to disassemble the double-row chain than the single-row chain. The single-row chain only needs to flush out the pin shaft until the outer chain plate comes out, while the double-row chain needs to completely flush out the pin shaft, and the design pushes Push the upper and lower outer chain plates and the middle chain plate. Due to the difficulty of dismantling the joints of the double-row chain, manual dismantling is generally used at present. The knocking force and position of the manual dismantling are different, and the labor intensity of the workers is high and time-consuming. Laborious, affecting processing efficiency and chain product quality

[0003] In the existing chain pre-drawing and dismantling device, such as the patent application publication number is CN108687300A, a kind of chain pre-drawing and dismantling integrated device is designed for single-row chains. For dismantling, the double-row chain The pin shaft is longer than the single-row chain. If the single-row chain is disassembled, the length of the punching needle and the movement stroke of the punching needle need to be lengthened. However, this method is difficult to ensure the stability of the stroke of the punching needle. In the actual use process, the service life of the punching needle is short and needs to be replaced frequently, which is one of the reasons why it is difficult to use automatic equipment to disassemble the double-row chain; and after the disassembly is completed, there will be two forms of the middle chain plate and the outer chain plate. Chain plates, the thickness of these two types of chain plates is different in most cases. If they are recycled by the conventional recycling method of single-row chains, due to their similar shapes, it will be difficult to sort them later, and the removed parts will be mixed together, which will increase the work of the operator. Difficulty and labor intensity

[0004] For pre-tensioning, hydraulic cylinders are generally used to preload the chain at present. This pre-tensioning method is costly, complicated in structure, and the oil pollution of the hydraulic station is serious, which does not conform to the current concept of green manufacturing; the sprockets of the pre-tensioning part Chain jamming and broken chains often occur at places, and the stability is poor. The chain will wear out the equipment due to vibration, and because the stability of the chain in the transmission process is not high, it will increase its wear and cause the product quality to decline.

[0005] Due to the large thickness of the double-row chain, there are high requirements for the chain engagement between pre-tensioning and disassembly and the chain engagement after disassembly. At present, the single-row chain only needs to adopt the structure of several guide wheels and one driving sprocket. The chain can be driven to complete the engagement and engagement of the chain, but when this method is applied to a double-row chain, the chain will appear unstable during the transmission process, and the entire device will often stop running due to chain running or jamming, resulting in delays duration
