Abstract
The utility model discloses a fork truck overhead guard for pipe bending rectangle save dnockout core, including the plug with set up in the fixed core of plug one end, the one end of fixed core is connected the plug, the other end of fixed core is provided with the mobile core that lives, live mobile core with fixed core hinge connects. A fork truck overhead guard for pipe bending rectangle save dnockout core, during the return bend fixed core is 2 millimeters apart from the circular arc tangential point, owing to adopt the pin junction the mobile core that lives can paste a tight pipe inner wall along with the curved system of tubular product, circular arc in the return bend because live mobile core near not producing the fold with sunken, when guaranteeing that fork truck overhead guard pipe bending size is accurate, the arc surface fold is sunken in can reducing, and the arc surface is more level and more smooth in making.
Description
Technical field
The utility model relates to a kind of fork truck and protects upper frame bend pipe processing rectangle joint core alive, belongs to fork truck manufacturing technology field.
Background technology
In the prior art, fork truck protects upper frame bend pipe and adds and usually adopt hard formula plug man-hour and coordinate pipe bender die to carry out bend pipe operation, its structure is as shown in Figure 1, mainly comprise bend pipe mill 6, along with the clamping block 7 of described bend pipe mill 6 synchronous axial system, and the guide plate 9 relative to the described static setting of bend pipe mill 6; During work, being inserted by hard formula plug 8 and jointly coordinate the angle of maintenance tubing one end constant in tubing and with described guide plate 9, then bend pipe mill 6 drives the other end rotation of tubing to carry out bending operation by described clamping block 7.
In above-mentioned operation process, the on position of hard formula plug in tubing is the important factor affecting bend pipe processing quality, if the position in insertion tubing is too forward, it is possible to meeting squeeze crack pipe; If the position in insertion tubing is too rearward, wrinkling inside bend pipe circular arc and depression can be caused again. Owing to hard formula plug shape of the prior art can not, along with being adjacent to tubing circular arc inwall when tubing bends, can only reach apart from 2 millimeters, circular arc point of contact place; From manufacture craft aspect, bend pipe Inner arc easily produces fold and depression, and Spring-back of Pipe Bending distortion is big, bend pipe size out of true, causes fork truck to protect upper frame part and installs out of true.
Chinese patent literature CN202087654U discloses a kind of bend pipe plug alleviating distortion, and it mainly comprises mandrel stem and the plug bulb for support bend pipe bend, mandrel stem and plug bulb hinged. Described articulated form is be provided with fixing chain nodal plate in mandrel stem, is provided with activity chain nodal plate in plug bulb, and fixing chain nodal plate is connected with activity chain nodal plate, and mandrel stem is fixedly connected with by pin with movable chain link with fixing chain nodal plate, plug bulb. Its exist deficiency be only applicable to small-bend radius bend pipe processing, for be applied to fork truck protect upper frame bend pipe processing, it may also be useful to poor effect.
Summary of the invention
The deficiency that the utility model exists for prior art just, it is provided that a kind of fork truck protects upper frame bend pipe processing rectangle joint core alive, and bend pipe Inner arc not easily produces fold and depression, and Spring-back of Pipe Bending distortion is little, and bend pipe size is accurate, meets actual service requirements.
For solving the problem, technical solution adopted in the utility model is as follows:
A kind of fork truck protects upper frame bend pipe processing rectangle joint core alive, comprise: plug and the fixed core being arranged at described plug one end, one end of described fixed core connects described plug, and the other end of described fixed core is provided with slide core, and described slide core and described fixed core are hinged.
As the improvement of technique scheme, also comprising union lever, the two ends of described union lever are respectively connected with described fixed core with described slide core respectively by a steady brace.
As the improvement of technique scheme, described fixed core is for connecting one end of described union lever for semicircle structure, for connecting, one end of described union lever is also semicircle structure to described slide core, and the free end of described slide core comprises side straight flange and another arc limit, side, and the radian on the arc limit of described slide core is less than the bend pipe radian that needs bend.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
A kind of fork truck described in the utility model protects upper frame bend pipe processing rectangle joint core alive, during bend pipe, described fixed core is apart from 2 millimeters, circular arc point of contact, due to adopt pin connect described slide core can be adjacent to pipe material inner wall along with bending of tubing, bend pipe Inner arc due to described slide core near producing fold and depression; Ensureing that fork truck protects upper frame bend pipe finish size accurately simultaneously, it is possible to reduce inner arc surface fold depression, make inner arc surface more smooth.

Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 2 to Figure 3, for a kind of fork truck described in the utility model protects upper frame bend pipe processing rectangle joint cored structure schematic diagram alive.
A kind of fork truck described in the utility model protects upper frame bend pipe processing rectangle joint core alive, comprising:
Plug 1 and the fixed core 2 being arranged at described plug 1 one end, one end of described fixed core 2 connects described plug 1, and the other end of described fixed core 2 is provided with slide core 3, and described slide core 3 and described fixed core 2 are hinged. Further with improvement, also comprising union lever 4, the two ends of described union lever 4 are respectively connected with described fixed core 2 with described slide core 3 respectively by a steady brace 5. Further optimally, described fixed core 2 is for connecting one end of described union lever 4 for semicircle structure, for connecting, one end of described union lever 4 is also semicircle structure to described slide core 3, and the free end of described slide core 3 comprises side straight flange and another arc limit, side, and the radian on the arc limit of described slide core 3 is less than the bend pipe radian that needs bend.
As shown in Figure 4, during work, one end of tubing is fixed in clamping block 7, a kind of fork truck described in the utility model is protected in the other end that upper frame bend pipe processing rectangle joint core 10 alive stretches into tubing, and jointly coordinate with described guide plate 9 and keep the angle of tubing one end constant, then bend pipe mill 6 drives the other end rotation of tubing to carry out bending operation by described clamping block 7.
Bend protect upper frame thin-wall pipe time a kind of fork truck described in the utility model protect upper frame bend pipe processing rectangle joint live core 10 can be adjacent to pipe material inner wall along with bending of tubing: during bend pipe, described fixed core 2 is apart from 2 millimeters, circular arc point of contact, due to adopt pin connect described slide core 3 can be adjacent to pipe material inner wall along with bending of tubing, bend pipe Inner arc due to described slide core 3 near producing fold and depression.
In addition, it is less than the arc limit of the bending bend pipe radian of needs by arranging radian, bends shaping rear described slide core 3 and also can easily extract tubing out.
Above content is the detailed explanation done by the utility model in conjunction with specific embodiments, can not assert that the utility model specifically implements to be only limitted to these explanations. For the utility model person of ordinary skill in the field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should be considered as belonging to the scope of the utility model protection.
