Problems solved by technology

[0003] However, manual crushing also has its shortcomings. First, when manual crushing is performed, the crushing efficiency is low.
Second, when crushing by hand, the crushing personnel must be in close contact with the abra

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0027] See Figure 1-Figure 6 , a sintered abrasive particle crushing device, including a frame 1, a hammer head 2, a hammer seat 3, a connecting rod 4, a Scotch yoke 8, and a motor 7; both the hammer head 2 and the hammer seat 3 have a ladder structure of more than four levels ( figure 1 is a five-level ladder structure), the step surface is a downwardly inclined slope, the hammer seat 3 is a circular platform structure as a whole, and the top surface is a conical surface; when the hammer head 2 and the hammer seat 3 are buckled together, the bottom two steps The gap is zero, and the buckling gap of other steps increases sequentially from bottom to top; the hammer base 3 is fixed on the bottom plate of the frame 1, the top of the hammer head 2 i...

Abstract

The invention relates to a sintered abrasive grain crushing device and method. The device comprises a rack, a hammer head, a hammer seat, a connecting rod, a scotch yoke and a motor. The hammer head and the hammer seat are each of a step structure with four or more stages, the step faces are inclined faces inclined downwards, and the hammer seat is overall of a circular table structure. When the hammer head and the hammer seat are buckled, the buckling gap of the two stages of steps on the bottommost layer is zero, and the buckling gaps of other steps are sequentially increased from bottom totop. The hammer seat is fixed to the bottom of the rack. The top of the hammer head is fixedly connected with the connecting rod. The top of the connecting rod is fixedly connected with the scotch yoke, an output shaft of the motor is arranged in the scotch yoke, and the scotch yoke is driven by the motor to drive the connecting rod to do vertical reciprocating motion. The device has the advantages that the multi-step hammer head and hammer seat structure is adopted, the crushing efficiency is effectively improved, and splashing of abrasive grain scraps is avoided; and by means of the design of sliding pins and sliding grooves, it is effectively guaranteed that the hammer head only does straight-up and straight-down reciprocating crushing motion, and then the cutting edge quality of an abrasive grain surface grinding phase is guaranteed.

Description

technical field [0001] The invention relates to a crushing device and method for sintered abrasive particles, in particular to a non-slip hammer crushing device and method for preparing abrasive particles. Background technique [0002] In the field of magnetic grinding, magnetic abrasives are widely used. As a tool for magnetic grinding, the grinding performance of magnetic abrasive directly restricts the promotion and application of magnetic grinding technology. In the process of preparing magnetic abrasives, the crushing process of sintered magnetic abrasives is mostly done manually, mainly because the current particle crushing equipment cannot complete the crushing work or the abrasive particles obtained after crushing cannot meet the process requirements. For example, in the traditional jaw crusher, due to the limitation of its crushing principle, the abrasive particles will inevitably slip under the squeezed state during the crushing process, and the extrusion and slid...
