Abstract

The invention relates to a cutterhead used for derusting and peeling a round billet in a steel mill, and the cutterhead is in a single-plate structure. A cutterhead body is provided with 2-9 equant zones for installing tool rests, and each equant zone is respectively provided with at least two groups of key grooves and screw holes for connecting the tool rests. Each group of key grooves and screw holes on the cutterhead body are respectively fixedly connected with one group of cutterheads by virtue of key positioning and screw groups, so that the cutterheads in the same group are tightly clamped by virtue of the key positioning and screw groups to quickly obtain different evenly-distributed tool positions so as to realize that one cutterhead can be used for processing round steel bar stocks of different specifications. When the cutterhead is subjected to toolsetting, the cutterhead does not need to be removed from derusting equipment, and the operation is quick and simple; each equant zone is respectively provided with multiple groups of key grooves and screw holes for connecting the tool rests; and the tool positions of different round billet diameters can be quickly obtained. The cutterhead has the characteristics of simple structure and the like, and is convenient to process, manufacture, install and maintain.

Description

The cutterhead that is used for steel mill's round steel billet rust cleaning peeling

Technical field

The present invention relates to a kind of cutterhead of machine cut processing, especially a kind of cutterhead that is used for iron and steel enterprise's round steel billet rust cleaning peeling machine.

Background technology

Cutterhead is extensive use of in iron and steel enterprise's round steel billet rust cleaning peeling machine (peeling machine).Aborning, cutting tool rotates at a high speed with cutterhead, round steel billet axis straight-line feed, thus the corrosion layer of round steel billet is divested.The technology of the present German original-pack equipment of domestic most employing, cutter head is double disk structure such as Fig. 1, shown in 2.3～4 knife rests 1 of the rust cleaning general uniform configuration of cutterhead.The uniform knife rest 1 of double plate rust cleaning cutterhead is fixed between the forward and backward cutterhead 3,4.Because more than the kind, the diameter of round steel billet was produced in every change surplus the round steel billet diameter specifications of every kind of material had ten approximately, just must adjust the cutting position of cutter.According to the production scene investigation, be unkitted directive wheel 2 in the processing, the peeling precision of round steel billet has satisfied required precision.When adjusting, need to unload cutterhead from production line, be transported to the toolsetting platform, unclamp forward and backward cutterhead 3,4, unload the lower slide parts and carry out toolsetting, and back tool rest uniform radially feather key guiding from cutterhead back positioning and locking of packing into is transported to production line again and is installed on the rust remover.

The characteristics of this class cutter head structure are to obtain different processing specifications by toolsetting within the specific limits, but whole toolsetting process is more loaded down with trivial details, and spent non-cutting time is longer.

Summary of the invention

The present invention will provide a kind of cutterhead that is used for steel mill's round steel billet rust cleaning peeling, and this cutterhead is simplified the toolsetting operation, shortens and produces non-cutting time, the positioning accuracy height, the scope of application is big, low cost of manufacture, and it is easy to use to be easy to processing and manufacturing, dismounting, assembling and production scene.

For achieving the above object, technical scheme of the present invention is: a kind of cutterhead that is used for steel mill's round steel billet rust cleaning peeling, be single-deck formula structure, comprise cutter head, be characterized in: cutter head be provided with two to nine dress knife rests etc. the subregion, each etc. be respectively provided to the keyway and the screw hole of few connection knife rest more than two groups on the subregion.

Each group keyway and screw hole are fixedlyed connected one group of knife rest by the positioning key location respectively on the cutter head with set screws, make same group of knife rest clamp the different uniform tool position of acquisition fast, thereby realize that a cutterhead processes the round steel bar of multiple different size by positioning key location and set screws.

Technique effect of the present invention is:

1) hilted broadsword dish structure, cutterhead need not to unload from rust removalling equipment during toolsetting, and operation is simple fast;

2) each etc. keyway and the screws that many groups connect knife rests are set respectively on the subregion, can obtain to process the tool position of different round steel billet diameters fast;

3) this apparatus structure is simple, processing and manufacturing and convenient for installation and maintenance.

4) the toolsetting mode is than rigidity.

Therefore, the present invention may extend to the production line that steel mill's rust cleaning round steel billet specification limit is big, required precision is higher, the production cycle is short.

The specific embodiment

The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.

Extremely shown in Figure 6 as Fig. 3, the cutterhead that is used for steel mill's round steel billet rust cleaning peeling of the present invention, be single-deck formula structure, cutter head 5 be provided with two to nine installation knife rests etc. the subregion, each etc. be respectively provided to the keyway 6 and the screw hole 7 of few connection knife rest 1 more than two groups on the subregion.

As Fig. 7, shown in 8, uniform knife rest 1 is located on cutter head 5 and is clamped by positioning key 9 and four screws 8.Each etc. the keyway 6 and the screw hole 7 of the connection knife rest more than two groups or two groups are set respectively on the subregion, the position that keyway 6 and screw hole are 7 groups is determined by the round steel billet diameter specifications of required acquisition.On this cutterhead, same group of knife rest 1 can clamp with 8 groups on screw by positioning key 9 location and obtain different uniform tool positions fast, thereby realize that a cutter-head mechanism just can process the round steel bar of multiple different size and (can obtain the specification of four kinds of round steel billets as Fig. 3, can obtain the specification of six kinds of different round steel billets as Fig. 5), whole toolsetting process cutterhead need not to unload from rust removalling equipment.

As Fig. 7, shown in 8, with the eight equal parts cutterhead is example, during installation, by selected one group of positioning key 9 of the round steel billet diameter specifications of required acquisition and screw 8, quadruplet is had positioning key 8 assemble combined type knife rest 1 location and clamping on selected one group of keyway 6 and screw hole 7, so one group of combined type knife rest is located the 9 knife rest groups (can obtain the tool position more than four kinds on the cutterhead of branch series such as difference) that can obtain four kinds of different tool position varying numbers fast at this cutterhead by key; Because cutterhead is a single-deck formula structure, so the convenient disassembly of knife rest and tool rest.

Since the position accuracy demand height of cutterhead upper knife edge, so novel cutterhead possesses following characteristics:

A. novel cutterhead need satisfy accurate positioning requirements.

B. novel cutterhead is big to the scope of application of round steel billet specification.

C. low cost of manufacture is easy to processing and manufacturing.

D. dismantle, assembling and production scene be easy to use.
