Abstract
The utility model discloses a pressure head of a press machine, which comprises a support, wherein the support is provided with a hydraulic extrusion mechanism, a plurality of mold bases are uniformly distributed in the hydraulic extrusion mechanism, a return spring is arranged between every two mold bases, the inner surface of the mold base is embedded with a permanent magnet and is provided with a positioning pin, and the bottom surface of a mold is provided with a positioning hole fitted with the positioning pin. When being arranged or replaced, the mold only needs to be inserted in the mold base via the cooperation between the positioning pins and the positioning holes, and the permanent magnet embedded on the mold base can adsorb the mold. The utility model has the advantages of simple structure and convenient assembly or disassembly of the mold.
Description
Technical field
The utility model relates to a kind of parts on the machine of withholding, and specifically is a kind of compressing head of withholding that is convenient for changing mould.
Background technology
The machine of withholding is a kind of machine that is used to withhold the pipe fitting assembly.Its principle is by the head of burking machine mould metal joint to be applied convergent force, with metal joint firm withhold on supporting rubber (perhaps steel) pipe fitting.The existing head of withholding machine commonly used generally adopts 6-8 mould, the inner surface of movable pressure ring adopts ramp structure, a plurality of mould seats are formed a ring body and are sleeved in the movable pressure ring, the outer surface of mould seat adopts monocline face or double inclined plane structure, mould is installed on the inner surface of mould seat, between the mould seat back-moving spring is housed in twos, movable pressure ring is exerted pressure, withhold the pipe fitting assembly thereby finish by oil cylinder piston.Existing mould generally is installed on the mould seat by two kinds of versions: the one, and lock ring formula structure, the outer surface that is mould is provided with the ring-type pin, the mould seat is provided with corresponding circular hole, also be provided with the locking hole that communicates with circular hole on the axial sides of mould seat, thereby block the ring-type pin by retaining ring is housed in the locking hole, and then mould is installed on the mould seat; But the employing oat tail groove structure offers axial dovetail groove on the mould seat, and the outer surface of mould is provided with the dovetail muscle that adapts with dovetail groove, mould is inserted from the axial sides of mould seat install, and locks by locking mechanism again.All there is the more very inconvenient shortcoming of mold exchange in these two kinds of versions, and the complex structure of mould and mould seat, have also increased production cost.
The utility model content
The technical problems to be solved in the utility model provides a kind of compressing head of withholding of for convenience detach and installation mold.
For solving the problems of the technologies described above, what provided withholds compressing head, comprise bearing, the hydraulic extrusion press structure is housed on the bearing, be evenly equipped with a plurality of mould seats in the hydraulic extrusion press structure, between the mould seat back-moving spring be housed in twos, its design feature is to be embedded with permanent magnet on the inner surface of mould seat, also be provided with alignment pin on the inner surface of mould seat, the bottom surface of mould is provided with the locating hole that adapts with alignment pin.
After adopting said structure, owing to be embedded with permanent magnet on the inner surface of mould seat, also be provided with alignment pin on the inner surface of mould seat, the bottom surface of mould is provided with the locating hole that adapts with alignment pin, when needs are installed or more during mold exchange, only the cooperation of mould by alignment pin and locating hole need be inserted on the mould seat, the permanent magnet of setting-in can adsorb mould on the mould seat.The utility model is simple in structure, and the installation or removal mould is very convenient.
Described hydraulic extrusion press structure comprises the steel tube body that is packed on the bearing, the two ends of steel tube body are by left end cap and right end cap sealing, be equipped with on the right end cap and move back mould oil cylinder, the oil connection that communicates with its inner chamber is installed on the sidewall of steel tube body, the steel tube body inner chamber is equipped with the piston that left end cap is passed in the end, the inner chamber of piston is the pickup passage, the movable pressure ring of stretching in the right part of piston is fixed with, described mould seat is distributed on the inner surface of movable pressure ring, between the mould seat back-moving spring is housed in twos, described mould is contained on the inner surface of mould seat.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation after the utility model is vertically analysed and observe.
The specific embodiment
As depicted in figs. 1 and 2 withhold compressing head, comprise bearing 6, the hydraulic extrusion press structure is housed on the bearing 6, the hydraulic extrusion press structure comprises the steel tube body 7 that is packed on the bearing 6, the two ends of steel tube body 7 are by left end cap 8 and right end cap 9 sealings, right end cap 9 is equipped with two up and down and moves back mould oil cylinder 10, the oil connection 11 that communicates with its inner chamber is installed on the sidewall of steel tube body 7, steel tube body 7 inner chambers are equipped with the piston 12 that passes left end cap 8 in the end, the inner chamber of piston 12 is a pickup passage 13, the movable pressure ring of stretching in the right part of piston 12 is fixed with 14, be evenly equipped with a plurality of mould seats 1 (being generally 6-8) on the inner surface of movable pressure ring 14, back-moving spring 15 is housed between the mould seat 1 in twos, mould seat 1 and back-moving spring 15 surround a ring body, and axially to being equipped with two permanent magnets 2, the inner surface middle part of each mould seat 1 also is provided with alignment pin 3 on the inner surface of each mould seat 1, the bottom surface of mould 4 is provided with the locating hole 5 that adapts with alignment pin 3, and mould 4 can be inserted on the mould seat 1.Also can be provided with like this: be provided with locating hole on mould seat 1, mould 4 is provided with alignment pin 3.
The utility model is to use like this: in the time of need withholding the pipe fitting assembly, select the suitable mould 4 of size, mould 4 is inserted on the mould seat 1, the permanent magnet 2 that is provided with on the mould seat 1 can adsorb mould 4, from pickup passage 13, put into the pipe fitting that to withhold, by oil connection 11 injection pressure oil, piston 12 can move right by promotion activity pressure ring 14, owing to adopt ramp structure between movable pressure ring 14 and the mould seat 1, a plurality of mould seats 1 can move in opposite directions, the ring body diameter that mould seat 1 is formed diminishes, under the effect of mould 4 just metal joint firm withhold on supporting rubber (perhaps steel) pipe fitting, by moving back mould oil cylinder 10 piston 12 is pushed up back, under the effect of back-moving spring 15, the ring body diameter change that mould seat 1 is formed sets back greatly.When needs more during mold exchange 4, directly mould 4 is extracted from mould seat 1 and got final product, replace with new mould 4, very convenient.
