Embodiment 1

[0057] A simple processing and assembling system for a hydraulic hammer shell in this embodiment includes a bending mechanism 3 , a pressing mechanism 4 and a welding and fixing mechanism 2 . Specifically, combined with Image 6 , the lower side of the pressing bar fixing table 32 in the bending mechanism 3 is equipped with a pressing bar 35, and the pressing bar 35 is a metal plate vertically arranged, and the bottom end of the pressing bar 35 is an upper pressing die 36 with an arc surface, and the upper pressing die 36 is elongated, and its bottom surface is an arc-shaped surface, preferably an arc-shaped surface. The bending platform 34 of the bending mechanism 3 is arranged below the pressure bar fixing table 32, and the bending platform 34 is fixed with two lower dies 37, which are columnar and arranged in parallel, and the two lower dies 37 are about The longitudinal mid-section of the pressing bar 35 is symmetrically distributed, that is, on the horizontal projection ...

Embodiment 2

[0065] A simple hydraulic hammer shell processing and assembling system in this embodiment has the improvement that the distance between the centers of the lower die 37 and the upper die 36 is greater than the sum of the radii of the two, forming a certain gap with a width equal to that of the upper die 0.6 to 0.9 times the radius of 36, preferably 0.7 times, can achieve a larger bending angle, and can avoid the upper die 36 and the lower die 37 extruding the board and causing the local thickness of the board to change. In addition, the radial dimension of the lower die 37 is larger than that of the upper die 36 so that the die 36 has a certain pressing depth, otherwise it will be difficult to achieve a large angle of bending and interference will easily occur.

[0066] It is worth noting that the lower die 37 can be cylindrical, and more preferably, the top of the lower die 37 can adopt a flat top structure, that is, the top of the lower die 37 is a plane, such as Image 6 As...

Embodiment 3

[0069] A kind of simple hydraulic hammer shell processing and assembling system of this embodiment, its improvement point is that: the outside wall of box body 21 adopted is provided with collar 24, and the inner diameter of this collar 24 is equal to the size of through hole 23, and with The through holes 23 are arranged coaxially. The box body 21 can be set as a hollow structure, and the collar 24 can increase the structural strength. After being installed in the positioning shaft, it can play a main supporting role, and the through hole 23 will not be deformed after long-term use. In this embodiment, the distance between the baffle plate 25 and the positioning plate 22 is 1.4 times the thickness of the side plate 13 of the hydraulic hammer.

Abstract

The invention discloses a hydraulic hammer housing assembly method based on a bending and flattening technology, and belongs to the field of hydraulic hammer processing. The hydraulic hammer housing assembly method comprises the following steps of: cutting blank, bending and processing a lining plate and a top cover plate through a bending mechanism, and bending and processing side plates througha pressing and trimming mechanism; welding the side plates, and flattening and correcting the side plates by the pressing and trimming mechanism; welding by a welding and fixing mechanism, specifically, placing processed side plates into a gap between a box body of the welding and fixing mechanism and a baffle plate, welding and positioning by a fixed rod after a positioning shaft rod is utilizedfor fixing, and connecting the two side plates; and welding the lining plate and the top cover plate after fixing, lifting out the lining plate and the top cover plate out of the housing, and weldingthe top cover plate and the lining plate from the inner side after lifting out the outer housing, thereby completing welding assembly and processing. The hydraulic hammer housing assembly method utilizes the simple bending mechanism to bend a workpiece, and the pressing and trimming mechanism corrects the side plates after bending and welding, so that flatness before the side plates are assembledcan be guaranteed. The device is simple and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of hydraulic hammer processing, and more specifically, relates to a hydraulic hammer shell assembly method based on bending and flattening technology. Background technique [0002] The hydraulic hammer has become an important working tool of the hydraulic excavator. The hydraulic hammer is powered by hydrostatic pressure to drive the piston to reciprocate. When the piston strokes, it hits the drill rod at high speed, and the drill rod breaks solids such as ore and concrete. The outer casing of the hydraulic hammer is an important component of the hydraulic hammer. The welding quality of the outer casing of the hydraulic hammer will directly affect the service life and working effect of the hydraulic hammer. Although the existing welding equipment can use robots to weld the wear-resistant plates, clamping plates and main hole ribs on the side plates, the efficiency is low when bending and flattening the top c...
