Description

A kind of waveform liner plate

Technical field

The utility model is related to a kind of shoes, and in particular to a kind of ball mill waveform liner plate.

Background technology

Ball grinding machine lining board be make cylinder from abrasive body and material directly impact and friction for protecting cylinder, while The motion state that abrasive body can be adjusted using various forms of liner plates is helped with enhancing pulverization of the abrasive body to material In the mill efficiency for improving grinding machine, increase yield, reduces metal consumption, the setting of ball grinding machine lining board wave crest is primarily to improve Its ability of dribbling.Existing liner plate has the disadvantage that：

1. liner plate is to reduce wave crest rate of depreciation, wave crest is arranged to low-angle, limits its strip ability；

2. liner body is point contact with the contact of abrasive body steel ball, noise is larger；

3. liner body uneven thickness, each section heating is uneven when heat treatment, easy tos produce cooling rapidly deformation, liner plate is made to produce Raw shrinkage hole and crackle, cause mechanical performance to reduce.

Therefore, it is necessary to be improved to ball mill waveform liner plate, while ensureing its mechanical performance, its strip energy is improved Power reduces noise.

Invention content

It is good that in view of the above problems existing in the prior art, the purpose of the utility model is to provide a kind of wear-resisting properties, strip Ability is strong, the waveform liner plate of low noise.

To achieve the above object, the technical solution adopted in the utility model is as follows：

A kind of waveform liner plate, including liner plate matrix, the liner plate matrix downside has and ball mill barrel inner surface matches Arc surface, the left and right end of arc surface is separately connected the left plane and right plane, left plane and the right side that oriented arc surface center line extends The radial dimension of plane is identical, has waveform curved surface on the upside of the liner plate matrix, symmetrical on the waveform curved surface to set Have and runs through stepped hole.

As further technical solution, the left and right end of arc surface near the left plane and right plane is symmetrically arranged with Concave cutouts.

Compared to the prior art, the advantageous effects of the utility model are：

1. the utility model wave crest is arranged to wide-angle, strip ability is strong；

2. liner body is contacted with the contact of abrasive body steel ball for face, make simultaneously because there is the material of grinding to play buffering in groove With 7%-9% noises can be reduced；

3. the utility model left plane is identical with the radial dimension of right plane, to eliminate grinding dead angle；

4. the left and right end of liner body arc surface is symmetrically arranged with concave cutouts, impartial wall thickness, heat treatment can be used as a whole When each section homogeneous heating, cooling rapidly deformation can be avoided, its mechanical performance is effectively ensured.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model；

Figure label is schematically as follows：1- liner plate matrixes, 2- arc surfaces, 3- left planes, the right planes of 4-, 5- waveform curved surfaces, 6- runs through stepped hole, 7- concave cutouts.

Specific implementation mode

The technical solution of the utility model is described in further detail below in conjunction with attached drawing.

As shown in Figure 1, a kind of waveform liner plate, including liner plate matrix 1, the liner plate matrix downside has and ball mill barrel The arc surface 2 that inner surface matches, the left and right end of arc surface is separately connected the left plane 3 that oriented arc surface center line extends and the right side is flat Face 4, left plane 3 is identical with the radial dimension of right plane 4, to eliminate grinding dead angle.

1 there is waveform curved surface 5, liner body to be contacted for face with the contact of abrasive body steel ball on the upside of the liner plate matrix, simultaneously Due to there is the material of grinding to work as a buffer in groove, 7%-9% noises can be reduced；Left and right pair on the waveform curved surface 5 Claim to be equipped with and run through stepped hole 6, it is 86mm to take crest height, and wave crest is arranged to wide-angle, and strip ability is strong.

2 left and right end of arc surface near the left plane 3 and right plane 4 is symmetrically arranged with concave cutouts 7, as a whole It can be used as impartial wall thickness, each section homogeneous heating when heat treatment can avoid cooling rapidly deformation, its machinery is effectively ensured Performance.

It is last it is necessarily pointed out that：The foregoing is merely the preferable specific implementation modes of the utility model, but this The protection domain of utility model is not limited thereto, and any one skilled in the art discloses in the utility model In technical scope, the change or replacement that can be readily occurred in should be covered within the scope of the utility model.

Claims

1. a kind of waveform liner plate, including liner plate matrix, it is characterised in that：Have on the downside of the liner plate matrix and ball mill barrel in The arc surface that surface matches, the left and right end of arc surface is separately connected the left plane and right plane that oriented arc surface center line extends, left Plane is identical with the radial dimension of right plane, has waveform curved surface on the upside of the liner plate matrix, left on the waveform curved surface The right side is arranged with through stepped hole；The left and right end of arc surface near the left plane and right plane is symmetrically arranged with concave cutouts.
