Description

A kind of small U pipe molding clamping, which moves back, allows bit architecture

Technical field

The utility model relates to the technical fields of machining more particularly to a kind of small U pipe molding clamping to move back resigning knot Structure.

Background technique

In refrigerating field, with extensively, existing small U pipe at the time of molding, needs to complete on one device small U pipe Type, cutting and the movement of necking need to carry out necking movement after the cut, in the past clamping for clamping workpiece of the pattern of necking Interference is had when mobile, so that reducing die is unable to complete successfully workpieces processing, if reducing die is made longer, that will be significantly The difficulty of processing for increasing reducing die, will increase processing cost to the more demanding of reducing die.

Summary of the invention

In order to solve prior art problem, the utility model, which provides a kind of small U pipe molding clamping and moves back, allows bit architecture, passes through The clamping of reset can be slided afterwards outward, when molding, clamping can move backward, molding be completed, after cutting, in last necking work Position, clamping reset forward with workpiece, allow reducing die to be smoothly worked into workpiece, thus substantially reduce to reducing die Technique requirement, meanwhile, cost substantially reduces.

To achieve the above object, technical solution provided by the utility model are as follows: a kind of small U pipe molding clamping moves back resigning Structure, including rack, the rack two sides are equipped with the oil cylinder that two horizontal directions are oppositely arranged, and each oil cylinder end is connected with One fixture block, every piece of fixture block end slidably connect a clamping by a dovetail groove in the horizontal direction, the clamping with it is described A reset spring is equipped between fixture block makes the clamping be in the state stretched out outward, is equipped with a mold core between two clampings, The rack is additionally provided with a binder oil cylinder, and the binder oil cylinder drives a top clip mould and mold core cooperation limitation workpiece only It can small distance movement in the horizontal direction.

Preferably, the binder oil cylinder is arranged below the rack, and the binder oil cylinder is fixed with a crane, described Crane is slidably connected to the rack, and the crane end is equipped with the press mould, and the press mould is arranged in the mould Above core, binder cylinder efficient end and the rack are relatively fixed.

Preferably, the press mould is equipped with positioning thimble, and the mold core is equipped with the positioning cooperated with the positioning thimble Hole.

The utility model has the beneficial effects that

The utility model passes through the clamping that can slide and reset afterwards outward, and when molding, clamping can move backward, complete at Type, after cutting, in last necking station, clamping resets forward with workpiece, and reducing die is allowed smoothly to be worked into workpiece, The technique requirement to reducing die is thus substantially reduced, meanwhile, cost substantially reduces.

Specific embodiment

With reference to the accompanying drawing and specific embodiment, the utility model will be further described:

Referring to figs. 1 to Fig. 3, a kind of small U pipe molding clamping, which moves back, allows bit architecture, including rack 1, and 1 two sides of rack are set The oil cylinder 2 for having two horizontal directions to be oppositely arranged, each 2 end of oil cylinder are connected with a fixture block 3, every piece of 3 end of fixture block A clamping 4 is slidably connected in the horizontal direction by a dovetail groove, and one is equipped between the clamping 4 and the fixture block 3 and resets bullet Spring 31 makes the clamping 4 be in the state stretched out outward, is equipped with a mold core 5 between two clampings 4, the rack 1 is also set up There is a binder oil cylinder 6, the one top clip mould 7 of the driving of binder oil cylinder 6 can only be along level side with the mold core 5 cooperation limitation workpiece Mobile to small distance, i.e., after top clip mould 7 and the mold core 5 cooperation, workpiece is still along the width direction of rack can be with thin tail sheep Mobile, after two fixture blocks 3 clamp workpiece, still it can be moved along the direction of dovetail groove.

Specifically, the binder oil cylinder 6 is arranged below the rack 1, the binder oil cylinder 6 is fixed with a crane 8, The crane 8 is slidably connected to the rack 1, and 8 end of crane is equipped with the press mould 7, and the press mould 7 is arranged Above the mold core 5,6 working end of binder oil cylinder and the rack 1 are relatively fixed, when binder oil cylinder 6 stretches out, press Mould 7 just moves down, and the moving direction for limiting workpiece is cooperated with mold core 5.

Specifically, the press mould 7 is equipped with positioning thimble 9, the mold core 5, which is equipped with, to be cooperated with the positioning thimble 9 When location hole 10, in this way press mould 7 and the mold core 5 cooperate, the position of cooperation is accurate.

When utility model works: workpiece is put into mold core 5, the driving press mould 7 of binder oil cylinder 6 to moving down, press mould 7 with Mold core 5 cooperates the moving direction for limiting workpiece, so that workpiece can only be moved along the width direction small distance of rack 1, two oil cylinders 2 Work, driving two fixture blocks 3 relative movement, two fixture blocks 3 drive two clampings 4 relative movement simultaneously, and step up workpiece, and clamping 4 with Fixture block 3 is to be connected by dovetail groove, therefore clamping 4 can be moved relative to fixture block 3 along the width direction of rack 1, the clamping 4 A reset spring 31 is equipped between fixture block 3 allows clamping 4 to be in the state stretched out, and therefore, in processing, clamping 4 can be according to water Square to power be moved forward and backward, to meet the processing needs that clamping moves back resigning.

The embodiments of the present invention are described in conjunction with attached drawing above, but the utility model be not limited to it is above-mentioned Specific embodiment, the above mentioned embodiment is only schematical, rather than restrictive, the common skill of this field Art personnel are not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model Under, many forms can be also made, these are belonged within the protection scope of the utility model.
