Embodiment 1

[0019] Such as figure 1 As shown, this embodiment includes an upper baffle and a lower baffle, the upper baffle and the lower baffle are connected by screws 4 , and the lower baffle is fixed on the external crimping machine 1 . The upper baffle and the lower baffle are connected, and a certain angle is formed between the two, so that it can more comprehensively protect the metal fragments ejected from all directions and endanger the construction personnel operating in the front; the lower baffle is fixed on the external crimping machine 1 , the bottom of the crimping machine 1 frame is fixedly connected with the lower baffle, which provides a safe operating environment for the construction personnel, and overcomes the defects that the construction personnel do not take safety protection measures or only take partial safety measures in the traditional crimping process, It is conducive to the safe and efficient operation of the process.

Embodiment 2

[0021] Such as figure 1 As shown, on the basis of Embodiment 1 in this embodiment, the upper baffle includes an upper frame 2 and an upper baffle glass 5, and the upper baffle glass 5 is fixed in the upper frame 2 by screws 4; the lower baffle It includes the lower frame 3 and the lower baffle glass 6 , the lower baffle glass 6 is fixed in the lower frame 3 by screws 4 , and the angle between the upper baffle and the lower baffle is 120o-150o. The set upper baffle glass 5 is transparent, which is convenient for construction personnel to observe the progress of the process. The connection between the upper baffle and the lower baffle is realized by welding the upper frame 2 and the lower frame 3. The screw 4 between the baffle glass and the baffle is connected Facilitate the installation and removal of the baffle glass.

[0022] The included angle between the upper baffle and the lower baffle is in the range of 120o to 150o, which is conducive to observing the progress of the ...

Abstract

The invention discloses a protection structure for a hush pipe production. The protection structure for the hush pipe production comprises an upper baffle and a lower baffle. The upper baffle and the lower baffle are connected by bolts, and the lower baffle is fixedly arranged on an external curling machine. The upper baffle and the lower baffle are connected and form a certain angle, so that metal chips jumping all around are more comprehensively prevented from endangering constructors operating front; the lower baffle is fixedly arranged on the external curling machine, and the bottom part of the rack of the curling machine is fixedly connected with the lower baffle, so that a safe operating environment is provided for the constructors, and the defect that the constructors do not adopt safety protection measures or only adopt local safety measures in a traditional curling process is overcome, and processes can be favorably performed safely and efficiently.

Description

technical field [0001] The invention relates to the field of engine exhaust mufflers, in particular to a protection structure for producing mufflers. Background technique [0002] The manufacturing process of the automobile muffler is roughly as follows: First, the rolled plate needs to be cut with a shearing machine, cut to a suitable size and rolled into a cylindrical shape with a circular machine; The middle seam is combined with positive and negative bending on both sides, and the lap joint is pressed out with a hydraulic embossing machine. The forming machine can make the cylinder body into various specifications and shapes, such as round, square, oval, triangular, etc.; Both ends of the cylinder body are crimped, and after the crimping is completed, the cylinder body is combined with the covers at both ends; finally, after the cylinder body is manufactured, the exhaust pipe is processed by pipe bending machines, tube expanders, tube shrinkers and other pipe process...
