Abstract
The invention relates to a prestretching die for stretching a filter outer shell assembling block. The prestretching die for stretching the filter outer shell assembling block is characterized in that the prestretching die comprises a lower die body and an upper die body which are matched with each other; the lower die body comprises a lower base plate, the lower base plate is provided with a supporting column, a supporting column flange is arranged on the lower side of the supporting column, an ejector rod is mounted on the upper side of the supporting column, the ejector rod is sleeved with a downward pressing pipe column, and a set of buffer springs are arranged between the lower side face of the downward pressing pipe column and the upper side face of the supporting column flange; the upper die body comprises an upper ejection plate, an upper push rod is arranged on the lower side of the upper ejection plate, and a stretching hole which is correspondingly matched with the ejector rod is formed in the bottom of the upper push rod. The prestretching die has the advantages that after a stretched filter outer shell is subjected to forward prestretching, the assembling block is fully deformed, and the phenomenon that the filter outer shell is deformed when the assembling block is formed is avoided; in addition, the prestretching die is simple in structure, convenient to operate and low in cost.
Description
Technical field
The present invention relates to the processing unit (plant) of thread cover plate for cleaner, particularly relate to a kind of prestretched mould for the filter casing assembled block that stretches.
Background technology
Air filter is arranged in engine aspirating system, the assembly that it is made up of the filter component of one or several clean air.Its Main Function is that filtering will enter objectionable impurities in the air of cylinder, to reduce the premature wear of cylinder, piston, piston ring, valve and valve seating.Engine has air, machine oil, hydraulic pressure three kinds of cleaners, is generally called " three filters ".They undertake the filtration of engine aspirating system, lubricating system and combustion system medium respectively.
Filter casing is the vitals of cleaner, present stage is when assembling and keep in repair cleaner, need the special vice used can be, filter casing is loaded onto or is unloaded, because the volume of special vice is larger, it is not very convenient to use, also have at present and weld a nut on the top of filter casing, then spanner is used to operate, but there is following shortcoming in this kind of mode: because filter casing is thinner, when welded nut, easily filter casing is punctured, scrappage is higher, difficulty of processing is large, after long-term time, weld seam gets rusty easily, reduce the weld strength of shell and nut.Therefore present stage is badly in need of wanting a kind of frock solved the problems of the technologies described above for use, and studying for a long period of time through the applicant, now develops a set of combination and touch, the prestretched mould during the application's group will protect combination to touch.
Summary of the invention
The object of the invention is to solve the shortcoming existed in prior art, and a kind of prestretched mould for the filter casing assembled block that stretches proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of prestretched mould for the filter casing assembled block that stretches, it is characterized in that: comprise the counterdie and patrix that cooperatively interact, described counterdie comprises lower shoe, described lower shoe installs support column, support column flange is provided with in the downside of described support column, install push rod in the upside of described support column, on described push rod, socket presses down tubing string, presses down between the downside of tubing string and described support column flange upper side and is provided with pool of buffer spring; Described patrix comprises upper plate, is provided with upper push-rod in the downside of described upper plate, is provided with the stretchable holes with described push rod corresponding matching in the bottom of described upper push-rod.
Preferably, described push rod is cylindrical bar, and described stretchable holes is the cylindrical bore with described push rod corresponding matching.
Preferably, be provided with three guide fingers described pressing down between the downside of tubing string and described support column flange upper side, described buffer spring correspondence is socketed on corresponding guide finger,
Preferably, described three guide fingers are arranged on described support column flange center, and to be the center of circle circumferentially same, and the line of three guide finger axis composition equilateral triangle.
The invention has the advantages that: a kind of prestretched mould for the filter casing assembled block that stretches provided by the present invention, stretching filter casing is after the prestretched of prestretched mould forward, assembled block is fully out of shape, avoid assembled block when shaping, filter casing deforms, and this apparatus structure is simple, easy to operate, cost is low.
