Description

A kind of apparatus for bending of multitube bending machine

Technical field

The utility model is used for industrial automation equipment production field, and the bending more particularly to a kind of multitube bending machine fills It sets.

Background technique

With economic globalization, production is efficient, higher and higher to the capacity requirements of bending machine, thus multitube folding occurs Bender.Apparatus for bending plays the forming quality of bend pipe conclusive as the important component in multitube bending and forming technique Effect, and with the increase of tubing quantity, in place of existing apparatus for bending comes with some shortcomings, most of existing multitube bending For the circle mould of machine by the way of fixed, the circular groove size for limiting tubing is constant, if being set as without the mode clamped in advance, in bending half In the lesser situation of diameter, tubing is unable to fully the limitation by circular groove during bending, and section is easy to appear largely Ovalization, if there is pre- clamping, it will cause the increases of tubing feeding resistance, may damage tube surfaces, thus can not combine Bending quality and surface quality, and part has the existing apparatus for bending of clamping and release function, structure is complex, and part is more And installation is inconvenient, motor requires power also larger, and overall cost is higher.

Utility model content

A kind of structure that in order to overcome the deficiencies of the prior art, the utility model provides is simple, it is easy for installation, can convenient reality The apparatus for bending of the multitube bending machine of existing clamping and release switching.

The bending mechanism includes the attachment base and link block of pedestal, two round moulds, the described two round moulds of connection, the company It is equipped with bearing between joint chair and the round mould, bushing is equipped between the link block and the round mould, is equipped with below the round mould The rack gear of gear, the gear and cylinder driving cooperates, to can realize that the linear motion by the cylinder is converted to the circle The rotary motion of mould.

The round mould is equipped with multiple tube seats, depending on quantity is according to the required quantity for processing tubing, the three of the tube seat / bis- parts are arc groove, and for realizing the clamping to tubing, remaining one third part is elliptic arc slot, the elliptic arc Slot area of knockout is greater than the arc groove, for realizing the release to tubing.

By the combination of above-mentioned part, can realize: when the cylinder drives the rack gear to stretch out, the gear is driven The round mould rotation, the elliptic arc slot are drawn close to tubing, form biggish port, so that tubing is unclamped, it can be to described Tubing is fed without generating too big resistance, and after the completion of feeding, the cylinder drives the rack gear to retract, the gear The round mould reversion is driven, the arc groove is drawn close to tubing, realizes the clamping to the tubing, and can protect during bending Clamping is held, so as to complete bend pipe processing in higher quality.

The utility model has the beneficial effects that the part by negligible amounts is combined, round mould can be realized to tubing It clamping and unclamps, solve when bending radius is smaller, fixed round mould cannot be considered in terms of the problem of bending quality and surface quality, And part needed for clamping and release movement switching is less, structure is simple, while being easily installed maintenance, Material Cost is relatively low.

Specific embodiment

Referring to Fig. 2 to Fig. 5, which show the specific structures of the preferred embodiment of the utility model, will be detailed below The design feature of each part of the utility model, and when if there is being described to direction (upper and lower, left and right, before and after), it is with Fig. 2 Shown in structure be with reference to description, but the actual use direction of the utility model is not limited thereto.

The utility model provides a kind of apparatus for bending of multitube bending machine, and the bending mechanism includes 1, two circle of pedestal The attachment base 3 and link block 4 of mould 2, the described two round moulds 2 of connection, are equipped with bearing 5 between the attachment base 3 and the round mould 2, It is equipped with bushing 6 between the link block 4 and the round mould 2, gear 7 is housed below the round mould 2, the gear 7 drives with cylinder 8 Dynamic rack gear 9 cooperates, so that the rotary motion that the linear motion of the cylinder 8 is converted to the round mould 2 can be realized.

The round mould 2 is equipped with multiple tube seats, depending on quantity is according to the required quantity for processing tubing, the three of the tube seat / bis- parts are arc groove 10, and for realizing the clamping to tubing 12, remaining one third part is elliptic arc slot 11, described 11 area of knockout of elliptic arc slot is greater than the arc groove 10, for realizing the release to tubing 12.

By the combination of above-mentioned part, can realize: when the cylinder 8 drives the rack gear 9 to stretch out, the gear 7 The round mould 2 is driven to rotate, the elliptic arc slot 10 is drawn close to tubing 12, biggish port is formed, thus by 12 pine of tubing It opens, the tubing 12 can be fed without generating too big resistance, after the completion of feeding, the cylinder 8 drives described Rack gear 9 retracts, and the gear 7 drives the round mould 2 to invert, and the arc groove 10 is drawn close to tubing 12, realizes to the tubing 12 clamping, and can keep clamping during bending, so as to complete bend pipe processing in higher quality.

By designing above, the utility model just realizes round mould to tubing clamping and release by the part of negligible amounts Quick and convenient switching, circle mould clamped condition enhances the restraining force of arc groove, ensure that bending tube forming quality, and circle mould unclamps State then reduces frictional force when feeding, ensure that tube surfaces quality, to make multitube bending machine with well processed While performance, cost is relatively low, improves its cost performance.

Certainly, the utility model creation is not limited to above embodiment, and those skilled in the art are not disobeying Equivalent deformation or replacement can be also made under the premise of back the spirit of the present invention, these equivalent deformations or replacement are all contained in this Apply in claim limited range.
