Problems solved by technology
[0002] The existing manual chain pre-stretching process is to manually transfer the produced chains to the pre-stretching machine, one by one manual rocker for pre-stretching, and the generator power of the manual pre-stretching machine is relatively large and is always started. A lot of waste is caused. The existing manual chain pre-tensioning mode is labor-intensive and inefficient, which can no longer meet the needs of the existing market.

The invention relates to the field of mechanical equipment, in particular to an automatic chain pre-tensioning machine. The automatic chain pre-tensioning machine comprises a working table board, anda head chain fixing jig and a tail chain fixing jig which are used for clamping an elevator chain are arranged at the front and rear ends of the working table board, the head chain fixing jig can freely stretch out and draw back, and the tail chain fixing jig is fixed to the working table board; and the automatic chain pre-tensioning machine also includes a hydraulic oil cylinder capable of driving the head chain fixing jig to freely stretch out and draw back, a coupling is connected between the head chain fixing jig and the hydraulic oil cylinder, a motor capable of controlling oil pressure conveying of the hydraulic oil cylinder is arranged beside the hydraulic oil cylinder, and the motor is connected with a control cabinet capable of regulating and controlling the pre-tensioning force and the pre-tensioning time of the pre-tensioning machine. The automatic chain pre-tensioning machine has the beneficial effects that the work efficiency and the product quality of a professional production line of a workshop are improved, the economic benefit is improved, the installation flexibility is large, the machine is more humanized, and the burden of an operator is reduced.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to an automatic chain pre-drawing machine. Background technique [0002] The existing manual chain pre-stretching process is to manually transfer the produced chains to the pre-stretching machine, one by one manual rocker for pre-stretching, and the generator power of the manual pre-stretching machine is relatively large and is always on. A large amount of waste is caused, and the existing manual chain pre-tensioning mode has high labor intensity and low efficiency, and cannot meet the needs of the existing market. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic chain pre-tensioning machine, which can realize automatic chain pre-tensioning, save manpower, improve work efficiency and reduce waste. [0004] In order to solve the above technical problems, the present invention is achieved through the follow...
