Continuous punching and shearing machine

Abstract

The invention discloses an on-line continuous punching and shearing machine suitable for hollow guide rails. The continuous punching and shearing machine comprises a reciprocating running system, a punching system and a control system. The reciprocating running system comprises a slide rail base, a sliding execution member arranged inside the slide rail base and a slide rail which is disposed on the bottom surface of the slide rail base. The punching system comprises a movable die frame, a die group and a hydraulic execution member, wherein the movable die frame can move on the slide rail base along the slide rail, the die group is used for punching and shearing, and the hydraulic execution member is used for driving the die group to act. The control system comprises a master controller used for controlling the sliding execution member and the hydraulic execution member. The continuous punching and shearing machine has the advantages that field environments are improved, punching and shearing processes are combined, the production efficiency is greatly improved, the occupied area of processes is reduced, costs caused by back-and-forth transportation by workers are reduced, the labor intensity is reduced, a rodless cylinder is used for transmission, the structure is compact, the precision is high, and sizes of guide rails can be well guaranteed during shearing.

Description

technical field [0001] The invention relates to processing equipment for hollow rails, in particular to an online continuous punching and shearing machine suitable for hollow rails. Background technique [0002] The guide rail is a relatively important part in the manufacture of elevators. As far as the structure of the guide rail itself is concerned, it is divided into two types: solid guide rail and hollow guide rail. [0003] Before the hollow guide rail is filled with fillers, it is first rolled from the plate; then the continuous material drawn from the rolling line is cut to form a figure 1 section-by-section rails as shown, and then on the figure 1 Both ends of the hollow rail shown are punched with a certain number of mounting holes for mounting. [0004] There is still no equipment that can directly realize the two processes of shearing and punching on the rolling line, so the current production process has the following problems: [0005] 1. The on-site environm...

AI Technical Summary

Problems solved by technology

[0005] 1. The on-site environment is poor: the cutting machine on the rolling line cuts with heavy oil and coolant smell, which affects the health of employees

[0006] 2. Scattered process: In the original processing technology, stacking after rolling and cutting, and then flowing into the next process for punching, the workshop occupies a large area, and the work efficiency is low, the labor intensity of the workers is relatively high, and the labor cost is too high
