Abstract
The utility model discloses a marking knife device for a medium-and-large free forging hydraulic press. The marking knife device for the medium-and-large free forging hydraulic press comprises a marking knife lower anvil block; a groove is formed in the upper portion of the marking knife lower anvil block, and a marking knife body is arranged in the groove; the marking knife body is fixedly connected with the groove of the marking knife lower anvil block through a fixed key; the heat treatment hardness HB of the marking knife body ranges from 302 to 340. The marking knife device for the medium-and-large free forging hydraulic press further comprises a hydraulic press upper anvil, and the hydraulic press upper anvil corresponds to the marking knife lower anvil block in up-and-down position. According to the marking knife device for the medium-and-large free forging hydraulic press, the marking knife on the knife anvil block is quick and safe to operate and accurate in sizing in the using process; through the utilization of the marking knife on the knife anvil block, the phenomenon that workers have to use an upper anvil and a lower anvil of the press to carry out cutting in a staggered mode when cutting of large forged pieces can not be carried out by utilizing manual marking knives is thoroughly avoided, and damage to a press system is prevented.
Description
Technical field
The utility model relates to a kind of marking knife device, is specifically related to a kind of medium-and-large-sized hydraulic press for free forging marking knife device.
Background technology
First operation that medium-and-large-sized hydraulic press for free forging forges is just made part by ingot head opening, the mouth of a river and is earnestly fallen to process; in forging process; after often steel ingot cogging can being pressed into less rectangular, dividing and be cut to several sections; and then be forged into several little forging or directly the forging material of holding base successfully offered to electric liquid hammer or subpress carries out secondary forging, particularly in forging, also need to do impression when large-scale Step Shaft and process.Completed in the past these operations and generally all use artificial marking knife manual operation to cut or impression etc., this not only often makes marking knife be pressed into several joints, press and fly the far forger life security that jeopardizes, and it is just helpless to run into larger cogging, chops efficiency very low simultaneously.
Shortcoming:
1, because artificial marking knife is very heavy, need two or three people could operate, marking knife and pole handle weld, and often can be pressed into several joints, several, and even pressure flies farly, seriously jeopardizes forger life security;
2, chop efficiency very low, little bar or scantlings are chopped all very difficultly exactly, and excision ingot head opening, the mouth of a river all can only be slow as plodding away at a big job bit by bit.
3, impression position is uncontrollable accurately, and efficiency is very low.
4, all consuming time, effort, danger are cut or impressed to incapability.
Utility model content
The utility model has overcome the deficiencies in the prior art, provides that a kind of operating efficiency is high, safety, scale medium-and-large-sized hydraulic press for free forging marking knife device accurately.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of medium-and-large-sized hydraulic press for free forging marking knife device, comprises anvil block under marking knife; Under described marking knife, anvil block top is provided with groove, is provided with marking knife body in described groove; Described marking knife body is fixedly connected with by retainingf key with the groove of anvil block under described marking knife; Described marking knife body heat treatment hardness HB is 302 to 340; Described medium-and-large-sized hydraulic press for free forging also comprises anvil on hydraulic press with marking knife device, and on described hydraulic press, anvil is corresponding with anvil block upper-lower position under described marking knife.
Further technical scheme is that under marking knife, anvil block is inverted T shape structure.
Further technical scheme is that marking knife tip is provided with blade, and described blade width is 25 to 35 millimeters.
Further technical scheme is that edge length is 100 to 150 millimeters.
Compared with prior art, the beneficial effects of the utility model are: swift to operate when the marking knife of the utility model on cutter anvil block uses, safety, scale are accurate.While using marking knife on the utility model cutter anvil block thoroughly to avoid using artificial marking knife can not carry out compared with the cutting of heavy forging, have to carry out blank with the dislocation of anvil up and down of press, solve press system harm problem.
Accompanying drawing explanation
Fig. 1 is embodiment of the utility model structural representation while using.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, structural representation when Fig. 1 shows embodiment of the utility model and uses.The medium-and-large-sized hydraulic press for free forging of the present embodiment marking knife device, comprises anvil block 1 under marking knife; Specific embodiment is that under marking knife, anvil block is inverted T-shaped structure, has like this steadiness.Under marking knife, anvil block top is provided with groove, is provided with marking knife body 2 in groove; Marking knife body is fixedly connected with by retainingf key with the groove of anvil block under marking knife; Marking knife body point is provided with blade, and preferably, blade width is 25 to 35 millimeters, and concrete is that blade width is 30 millimeters.Edge length is 100 to 150 millimeters, and specific embodiment is that edge length is 120 millimeters.Preferably, marking knife body heat treatment hardness HB is 302 to 340; The medium-and-large-sized hydraulic press for free forging of the present embodiment also comprises anvil 5 on hydraulic press with marking knife device, and on hydraulic press, anvil is fixed on hydraulic press, and on hydraulic press, anvil is corresponding with anvil block upper-lower position under marking knife.When use, manipulator 6 clamps the forging 4 that need cut and is positioned on marking knife body, cuts after fixing by anvil on hydraulic press.The present embodiment is very convenient, safety in the time of the impure part of excision ingot head opening, mouth of a river part; When being particularly pressed into square bar and need to being cut into several sections by the forging that arc anvil is pressed into bar by flat anvil, the marking knife of operative installations on cutter anvil block is very quick, safety, scale are accurate.Use the present embodiment device, marking knife on cutter anvil block have to carry out blank with the dislocation of anvil up and down of press while having avoided using in prior art artificial marking knife can not carry out compared with the cutting of heavy forging, it is that hydraulic press produces the serious eccentric evildoing forging that upper and lower anvil dislocation is cut, to press system harm and great.
" embodiment ", " another embodiment ", " embodiment " that spoken of in this manual, etc., refer to specific features, structure or the feature described in conjunction with this embodiment and be included at least one embodiment that the application's generality describes.In description, multiple local appearance statement of the same race is not necessarily to refer to same embodiment.Furthermore, while describing a specific features, structure or feature in conjunction with any embodiment, what advocate is to realize this feature, structure or feature in conjunction with other embodiment also to drop in scope of the present utility model.
Although the utility model is described with reference to the multiple explanatory embodiment of utility model here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and within embodiment will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to the building block of subject combination layout and/or layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
