Abstract
The utility model discloses a hammering block piece does not advance novel pneumatic hammer structure of helical pitch belongs to forging equipment technical field. This pneumatic hammer structure, including hammer stem on the piston of working cylinder, the piston that is located the working cylinder, connection, be located the hammer stem helical pitch of working cylinder lower part, the hammer stem lower extreme be connected with the hammering block piece, hammer stem length be to the minimum: lie in jar when point topmost when the piston, the lower extreme position of hammer stem is under the hammer stem helical pitch under the terminal surface. The overall dimension of the middle and upper hammering block piece of this structure does not completely receive the restriction of hammer stem helical pitch and hammer stem size, and the user can freely change the hammering block piece and go up the mould, has extended the range of application of pneumatic hammer greatly.
Description
Technical field
The utility model relates to a kind of pneumatic hammer structure, and particularly a kind of anvil block does not enter the Novel air pneumatic hammer structure of helical pitch, belongs to technical field of forging and pressing equipment.
Background technology
In recent years along with the develop rapidly of iron skill, chemical industry, operating theater instruments and hand-held tool industry, pneumatic hammer with it at a high speed, efficient and economic dispatch advantage is progressively widely used in forging industry.The upper anvil block (also known as mold) of pneumatic hammer plays vital effect in hammered work, the different requirements that the contour structures of different industries different user to upper anvil block has it special, and traditional old-fashioned pneumatic hammer is by the restriction of its physical dimension, the profile of upper anvil block can not be greater than the little cylindrical sectional dimension of coupled hammer stem, therefore on pneumatic hammer, anvil block contour structures is limited by very large, and cannot realize the requirement that a lot of user needs with self-designed larger special dies (namely going up anvil block).
Summary of the invention
The purpose of this utility model is to overcome the existing pneumatic hammer upper anvil block that is in operation and enters pneumatic hammer that helical pitch causes to the bad adaptability of mould, provides the Novel air pneumatic hammer structure that a kind of anvil block does not enter helical pitch.
For realizing the purpose of this utility model, the technical scheme that the utility model adopts is: anvil block does not enter the Novel air pneumatic hammer structure of helical pitch, comprise working cylinder, be positioned at the piston of working cylinder, be connected to the hammer stem on piston, be positioned at the hammer stem helical pitch of working cylinder bottom, described hammer stem lower end is connected with anvil block, described hammer stem length is minimum is: when piston be positioned at cylinder topmost put time, the lower end part of hammer stem is under hammer stem helical pitch lower surface, further, described hammer stem length is minimum is: when piston be positioned at cylinder topmost put time, the connecting portion of hammer stem and anvil block is under hammer stem helical pitch lower surface.
Positive Advantageous Effects of the present utility model is: the working portion hammer stem that in basis, anvil block does not enter helical pitch structure runs to anvil block on peak and do not enter working cylinder hammer stem helical pitch completely, the appearance and size of upper anvil block is not subject to the restriction of hammer stem helical pitch and hammer stem size completely, user can freely replace with anvil block and mold, greatly expand the range of application of pneumatic hammer, meet the demand of a large amount of users at home and abroad.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the contrast schematic diagram that upper anvil block enters hammer stem helical pitch.
Detailed description of the invention
In order to explain enforcement of the present utility model more fully, provide embodiment of the present utility model.These embodiments are only to elaboration of the present utility model, do not limit scope of the present utility model.
The utility model is described in more detail by reference to the accompanying drawings, is respectively labeled as in accompanying drawing: 1: working cylinder; 2: hammer stem; 3. hammer stem helical pitch; 4: upper anvil block; Two hammer stems that are shown in the drawings are positioned at situation topmost.Anvil block in the utility model refers to anvil block.As shown in drawings, enter on the basis of the pneumatic hammer of hammer stem helical pitch at the upper anvil block shown in Fig. 2, lengthen air hammer lever, ensureing that hammer stem length is minimum is: when piston be positioned at cylinder topmost put time, the lower end part of hammer stem is under hammer stem helical pitch lower surface, the hammer stem length optimized minimumly is: when piston be positioned at cylinder topmost put time, the connecting portion of hammer stem and anvil block is under hammer stem helical pitch lower surface, so more be conducive to dismantling anvil block, under the prerequisite not increasing hammer stem quality, hammer stem size outside diameter is reduced, under achieving the prerequisite ensureing former dropping weight, hammer stem lengthens and does not increase the weight of, and to the fuselage be associated, piston, helical pitch is improved, under the prerequisite ensureing original performance, achieve anvil block and do not enter working cylinder, freely can replace with the demand of mould, blow energy, operation interval height can accurately control, widen the pneumatic hammer scope of application
After detailed description embodiment of the present utility model, the personage being familiar with this technology can be well understood to, do not departing under above-mentioned claim and spirit and can carry out various change and amendment, all above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all belong to the scope of technical solutions of the utility model, and the utility model is not also limited to the embodiment of example in description.
Claims (2)
1. anvil block does not enter the Novel air pneumatic hammer structure of helical pitch, comprise working cylinder, be positioned at the piston of working cylinder, the hammer stem be connected on piston, be positioned at the hammer stem helical pitch of working cylinder bottom, it is characterized in that: described hammer stem lower end is connected with anvil block, described hammer stem length is minimum is: when piston be positioned at cylinder topmost put time, the lower end part of hammer stem is under hammer stem helical pitch lower surface.
2. anvil block according to claim 1 does not enter the Novel air pneumatic hammer structure of helical pitch, it is characterized in that: described hammer stem length is minimum is: when piston be positioned at cylinder topmost put time, the connecting portion of hammer stem and anvil block is under hammer stem helical pitch lower surface.
