Abstract
The invention discloses a forming die for a piston rod of a loading machine, and relates to the technical field of machining. The forming die comprises an upper extrusion die with an inner cavity, and a lower extrusion die with an inner cavity, wherein a perpendicular cylindrical hole which is communicated with the inner cavity of the upper extrusion die and leads to the exterior is formed in the upper portion of the upper extrusion die, a perpendicular cylindrical hole which is communicated with the inner cavity of the lower extrusion die and leads to the exterior is formed in the lower portion of the lower extrusion die, and horizontal semi-cylindrical holes are formed on one side of the upper extrusion die and the same side of the lower extrusion die respectively, and are communicated with the corresponding inner cavities; an upper extrusion head is arranged in the perpendicular cylindrical hole of the upper extrusion die, and connected with an upper die handle, and a lower extrusion head is arranged in the perpendicular cylindrical hole of the lower extrusion die, and connected with a lower die handle. The forming die can solve the problems that in the prior art, product accuracy is poor, the die manufacturing cost is high, and the working environment is poor.
Description
Technical field
The present invention relates to Machining Technology field, especially a kind of loading machine piston rod shaping mould.
Background technology
The operating cylinder of excavator is the vitals in engineering excavation machine, the piston rod of oil cylinder is under the alternating action of tension and compression, larger shock loading can be subject to, again because friction generates heat with filler close contact, piston rod self-temperature is raised, and such condition of work requires that piston rod blank must be forging, and machining accuracy is high, have very strong comprehensive mechanical performance, hardness is taller at the working temperature with filler contact site; Piston rod is elongate articles, and its forging is general in the past adopts traditional die hammer Forging Technology, and basic working procedure is heating furnace heating, pneumatic hammer base, die hammer are shaped and punch press trimming; There are the following problems for this traditional Forging Technology: one, severe operational environment, produces noise large; Two, equipment is large to ground vibration, and Equipment Foundations are complicated; Three, Product Precision is poor, and because die hammer guiding accuracy is poor, cause product die parting line to offset large, the monolateral allowance of product is large; Four, die manufacturing cost is high, and because forming process has very large impact, mould must design very huge, and to increase cushion faces, simultaneously owing to being shaped with impact, die wear is fast, causes die life low.
Summary of the invention
The object of this invention is to provide a kind of loading machine piston rod shaping mould, it can solve the problem of the high and poor working environment of prior art products low precision, die manufacturing cost.
In order to solve the problem, the technical solution used in the present invention is:
A kind of loading machine piston rod shaping mould, comprise the extruding counterdie that an extruding patrix with inner chamber and have inner chamber, the top of described extruding patrix is provided with and communicates with its inner chamber and to lead to outside vertical circular post holes, the bottom of described extruding counterdie is provided with and communicates with its inner chamber and to lead to outside vertical circular post holes, and described extruding patrix is provided with the same side of described extruding counterdie the horizontal semi-circular post holes communicated with respective inner chamber; Be provided with extrusion head in the vertical circular post holes of described extruding patrix, described upper extrusion head connects a patrix handle, is provided with lower extrusion head in the vertical circular post holes of described extruding counterdie, and described lower extrusion head connects a counterdie handle.
In above technical scheme, further: described extruding patrix bottom is cylinder, and described cylindrical bottom is the frustum of a cone; Described extruding counterdie top is cylinder, and described cylindrical upper end is the frustum of a cone.
Further: described patrix is provided with screw thread top, described counterdie is provided with screw thread bottom.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, adopt the shaping loading machine piston rod of Closed Hydraulic machine, thinner bar can be selected, and available electrical induction bar, blank heating is fast, and production efficiency is high, and blank surface oxidation greatly reduces, and forging surface quality is good;
2, Closed Hydraulic machine guiding accuracy is high, and forming process is extrusion molding, and the amount of mould offsetting is up and down very little, and the monolateral allowance of forging is little, and Product Precision is high, also can save material simultaneously;
3, in extrusion process without impact shock, extrusion die damage little, die life is high, and meanwhile, production environment noise is little, and contamination is greatly improved, and operator's labour intensity reduces greatly.
Accompanying drawing explanation
Fig. 1 is that installation shaping mould front view is carried in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is further described: as shown in Figure 1,
A kind of loading machine piston rod shaping mould, comprise the extruding counterdie 5 that an extruding patrix 3 with inner chamber and have inner chamber, the top of extruding patrix 3 is provided with and communicates with its inner chamber and to lead to the vertical circular post holes of outside, the bottom of extruding counterdie 5 is provided with and communicates with its inner chamber and to lead to outside vertical circular post holes, and extruding patrix 3 is provided with the same side extruding counterdie 5 the horizontal semi-circular post holes communicated with respective inner chamber; Extrusion head 2 is provided with in the vertical circular post holes of extruding patrix 3, upper extrusion head 2 is threaded a patrix 1, patrix is provided with the top of 1 on the screw thread be connected with hydraulic press, lower extrusion head 6 is provided with in the vertical circular post holes of extruding counterdie 5, lower extrusion head 6 is threaded a counterdie 7, counterdie is provided with the top of 7 on the screw thread be connected with hydraulic press, and described extruding patrix 2 bottom is cylinder, and cylindrical bottom is the frustum of a cone; Extruding counterdie 5 top is cylinder, and cylindrical upper end is the frustum of a cone.
Time shaping, piston rod blank 4 through base is put into the inner chamber of extruding the patrix 3 and extruding counterdie 5 being in matched moulds state, start Closed Hydraulic machine, now, hydraulic press drives patrix that 1 and upper extrusion head 2 are extruded from top to bottom, counterdie extrudes 7 and lower extrusion head 6 from the bottom up, and through extruding, the ball-type head of piston rod blank 4 is squeezed into the shape and size of technological requirement.
