Abstract
The utility model discloses a hand and electric operate hydraulic pipe bender, which is mainly used for bending and shaping a pipe in construction and boiler equipment industries etc, the utility model is characterized in that a high pressure changeover switch, a scale displayer and a mold opening pin are added base on the prior art, so the problems of poor sealing performance and oil leakage are solved in the prior art, and the defects of unavailable scale display in piston stretching stroke, different angle in batch pipe bending process, difficult mold opening practice and uneasy maintenance and so forth can be removed.
Description
One, technical field
The utility model relates to the used equipment of a kind of brake forming, goes into B29C53/00.
Two, background technology
The bending machine that the pipe bending moulding is used in the industries such as building, construction, boiler plant has manually and electric pipe bender at present.It is made up of parts such as the pump housing, manual pump, fuel tank, oil discharge screw, handle, bending die and fulcrum posts its basic structure as shown in Figure 1.This bending machine is used often, but the problem that exists is quite a few, and short service life as sealing ring, leakage of oil is more serious, and the flexible stroke of piston does not have scale to show, can't guarantee the uniformity of angle during the batch bend pipe; Demoulding difficulty and inconvenient maintenance etc.
Three, utility model content
The purpose of this utility model is to provide a kind of new type hydraulic bending machine to solve ubiquitous defective on all bending machines.This new type hydraulic bending machine electrohydraulic pipe bender on the other hand can adopt following technical scheme to implement: it is to increase the high pressure reversing switch on the basis of existing bending machine, scale display and stripper pin are formed, and it is designed to the hydraulic pipe bender of hand, electronic dual-purpose.According to above-mentioned thinking, torch hydrodynamic pressure bending machine is made up of parts such as fuel tank, manual pump, high pressure reversing switch, oil cylinder, handle, scale display (can make rule, fluid level indicator or other scale display format), stripper pin, bending die and fulcrum posts.Wherein manual pump, high pressure reversing switch are installed on the fuel tank cap, are connected with fuel tank by pipeline, and the scale display is contained on the support of oil cylinder piston bar leading section, move with the motion of piston rod, to show displacement.Stripper pin is contained in the hole on bending die and piston rod top, in case bending die is deviate from from piston rod during the demoulding, all the other structures and existing bending machine are same or similar, more than are the technical schemes of hand-hydraulic pipe bender.Only need when being used as electrohydraulic pipe bender and using advancing on the electrodynamic pump, back leakage connection are connected, starting switch can electronic work, and need not to use electrodynamic pump manually the time.Because advance, back leakage connection all is normally closed type, so get final product work as long as press the speed pump.This new type hydraulic bending machine just becomes the collection hand, electronicly is the dual-purpose bending machine of one, not only can be manually but also can be electronic.
Compare with existing bending machine according to the torch hydrodynamic pressure bending machine that technique scheme designs and produces, have following advantage: 1, collection hand, electronic for one, can alleviate bend pipe labour intensity, easy to use; 2, thoroughly solve the leakage of oil problem on the one hand behind the employing high pressure reversing switch, solved the demoulding on the other hand extremely easily; 3, the flexible stroke of piston has scale to show, can guarantee the uniformity of angle when the batch bend pipe.
Four, description of drawings
Fig. 1, existing bending machine structural representation.
Fig. 2, torch hydrodynamic pressure bending machine structural representation.
Five, the specific embodiment
Torch hydrodynamic pressure bending machine of the present utility model as shown in Figure 2, it is made up of fuel tank (1), back leakage connection (2), fuel inlet fitting (3), manual pump (4), high pressure reversing switch (5), oil cylinder (6), handle (7), scale display (8), stripper pin (9), bending die (10) and fulcrum post (11).Wherein manual pump (4), high pressure reversing switch (5) are installed on the upper cover plate of fuel tank (1), are connected with fuel tank by pipeline.Scale display (8) is contained on the support of oil cylinder piston bar front end, and stripper pin (9) is contained in the hole on bending die (10) and piston rod top.The installation of all the other parts and operating principle and existing bending machine are same or similar.When dressing up electric pipe bender and use, only need oil-feed, back leakage connection with advancing on the electrodynamic pump, back leakage connection and this machine to connect and get final product.When pressing the torch hydrodynamic pressure bending machine work that said structure forms, when the handle position of high pressure reversing switch when " advancing ", the piston of bending machine stretches out, the beginning bend pipe, when soon handle position was put into " moving back " after bending well, the piston rod of bending machine was return, and finishes the demoulding automatically.
Claims (1)
1, a kind of by fuel tank (1), back leakage connection (2), fuel inlet fitting (3), manual pump (4), oil cylinder (6), handle (7), bending die (10), and the torch hydrodynamic pressure bending machine formed of fulcrum post (11), it is characterized in that on the upper cover plate of fuel tank (1), being equipped with high pressure reversing switch (5), be connected with fuel tank by pipeline, scale display (8) is housed on the support of piston rod front end, in the hole on bending die (10) and piston rod top, stripper pin (9) is housed.
