Abstract
The invention discloses an impact crusher hammerhead and a production method for the same. According to the hammerhead and the production method, during production of the hammerhead (1) capable of being installed on a rotary shaft (2) of an impact crusher, the machining impact surface of the hammerhead (1) is produced as an arc curved surface (1.1), and the arc curved surface (1.1) is gradually bent from the front end of the lowest end of the impact surface of the hammerhead (1) along a direction opposite to the rotation direction of the hammerhead (1) during working from top to bottom, so that the hammerhead is formed. The hammerhead disclosed by the invention has the advantages of being relatively little in wear during working, relatively long in service life, simple in structure, capable of improving the machining efficiency of the impact crusher, reducing the operation cost and the maintenance workload, decreasing the energy consumption, etc.
Description
Technical field
The present invention relates to a kind of impact crusher hammer head and preparation method thereof, belong to the tup technical field that impact breaker is used.
Background technology
Impact breaker has advantages of that the ratio of reduction is large, operational efficiency is high, is widely used in the industries such as mine, building materials.At present, in the prior art, the employed hammehead structure of impact breaker generally is the tup of rectangular configuration, it all is the plane that the processing of the tup of this rectangular configuration impacts face, analyze after deliberation and find, when the tup that adopts this planar structure impacts processed material, material is when moving along the tangential direction of tup rotation direction, also can produce a transport motion that hits the plane motion of taking taxi along tup, the just existence of this transport motion makes material produce main frictional dissipation to tup.So this processing impact face be planar structure tup in actual use, exist that tup wearing and tearing are large, tup short problem in service life, and because the impact of the larger frictional force that tup and object to be processed produce all descends the transmission efficiency of whole impact breaker and operating efficiency to some extent; Simultaneously since the tup fittings cost increase increasing of the labour cost changed with tup, its expense that increases can be up to more than 60～80% of disintegrating machine operating cost, and to change the shared time of accessory also be considerable.So, the result of use of the tup of existing impact breaker or not ideal enough.
Summary of the invention
The objective of the invention is: impact crusher hammer head that wearing and tearing were less when a kind of work was provided, service life is long and preparation method thereof, to overcome the deficiencies in the prior art.
The present invention is achieved in that the preparation method of a kind of impact crusher hammer head of the present invention is, during tup on making the rotating shaft to be installed in impact breaker, the processing of tup is impacted face is made into arc-shaped curved surface, and make this arc-shaped curved surface from hitting of tup take taxi the front end bottom, the rightabout of rotation direction is crooked gradually during from top to bottom along this tup work.
When the radius of above-mentioned rotating shaft is R, the processing that is installed in the tup in the rotating shaft is hit the least significant end of taking taxi when being H to the height of the most significant end of tup, if the origin of coordinates 0 of a right-angle plane coordinate system with horizontal X axle and vertical Y axle is just in time on the central axis of rotating shaft, and the plane of this right-angle plane coordinate system is vertical with the central axis of rotating shaft, and the hitting to take taxi and before correct bottom on the Y-axis of this right-angle plane coordinate system of tup, take taxi bottom the front end from hitting of tup making arc-shaped curved surface, when the rightabout of rotation direction is crooked gradually during from top to bottom along the work of this tup, make tup should be satisfied following relationship by the coordinate (x, y) of every bit on the arc-shaped curved surface on the right-angle plane coordinate system phase truncation surface:
X≥(R+y)(tg△θ-△θ) ；
△θ=arccos[R/(R+y)] ；
In following formula, the span of y is: R≤y≤R+H.
The of the present invention a kind of impact crusher hammer head that makes up according to the method described above is: this tup comprises the tup in the rotating shaft that can be installed in impact breaker, and it is arc-shaped curved surface that the processing of tup impacts face.
The rightabout of rotation direction when the bending direction of above-mentioned arc-shaped curved surface is tup work.
Owing to having adopted technique scheme, the present invention impacts face with the processing of tup and is made into the arc-shaped curved surface shape, and this arc-shaped curved surface is taken taxi bottom the front end from hitting of tup, the rightabout of rotation direction is crooked gradually during from top to bottom along this tup work, like this, when using tup of the present invention to carry out processing work, the material that is impacted by tup is when making tangential motion, can not produce transport motion because of the effect of tup, that is to say, material can not produce friction to the face that impacts of tup, namely analyze theoretically, the material that is impacted only can produce elastic collision with tup.So, the present invention compared with prior art, wearing and tearing were less when the present invention not only had advantages of work, service life is long, but also had working (machining) efficiency simple in structure, as to improve impact breaker, reduce operating cost and reduce the advantages such as maintenance workload, reduction energy consumption.
Description of drawings
Fig. 1 is the structural representation of a tup of the present invention when being installed in the rotating shaft of impact breaker; Among Fig. 1 for for the purpose of being described clearly, supposed that the origin of coordinates 0 with right-angle plane coordinate system of horizontal X axle and vertical Y axle just in time is located on the central axis of rotating shaft; Curved arrow among Fig. 1 represents the rotation direction in rotating shaft when work of impact breaker.
Description of reference numerals: the 1-tup, the 1.1-arc-shaped curved surface, the 2-rotating shaft, the radius of R-rotating shaft, the height of least significant end to the tup most significant end of taking taxi hit in the processing of H-tup.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is done further to say in detail.
Embodiments of the invention: when making the tup of impact breaker, preparation method according to a kind of impact crusher hammer head of the present invention is made, the present invention improves on the basis of existing impact crusher hammer head to form, namely during the tup 1 on making the rotating shaft 2 to be installed in impact breaker, making material and the manufacture craft of this tup 1, and all adopt the production method of existing tup to make with the syndeton mode of rotating shaft 2, but when the processing of making tup 1 impacts face, the processing of tup 1 is impacted face be made into arc-shaped curved surface 1.1, and this arc-shaped curved surface 1.1 is taken taxi bottom the front end from hitting of tup 1, the rightabout of rotation direction is crooked gradually during from top to bottom along this tup 1 work; Namely the radius when rotating shaft 2 is R, the processing that is installed in the tup 1 in the rotating shaft 2 is hit the least significant end of taking taxi when being H to the height of the most significant end of tup 1, suppose that the origin of coordinates 0 of a right-angle plane coordinate system with horizontal X axle and vertical Y axle is just in time on the central axis of rotating shaft 2, and the plane of this right-angle plane coordinate system is vertical with the central axis of rotating shaft 2, and the hitting to take taxi and before correct bottom on the Y-axis of this right-angle plane coordinate system (as shown in Figure 1) of tup 1, take taxi bottom the front end from hitting of tup 1 making arc-shaped curved surface 1.1, when the rightabout of rotation direction is crooked gradually during from top to bottom along 1 work of this tup, make tup 1 should be satisfied following relationship by the coordinate figure (x, y) of every bit on the arc-shaped curved surface 1.1 on the right-angle plane coordinate system phase truncation surface:
x≥(R+y)(tg△θ-△θ) ；
