Description
Technical field
The present invention relates to steel plate bending mould, a kind of opening degree particularly for bending steel plate can self-adjusting counterdie.
Background technology
At present, in the production technology of straight-line joint submerged arc welding tube, the JCOE mode of production is comparatively popular, the principle of its main production equipments-forming machine is 3 bendings, be placed on the fixing counterdie (2 points) of opening degree by steel plate, patrix (a bit) is depressed, by steel plate 3 bendings, then according to processing step, flat board is progressively pressed into " O " type.When producing the steel pipe of different size, need the opening degree of corresponding adjustment counterdie.
As shown in Figure 1, to the conventional apparatus of lower die open degree adjustment lower die open degree realize by the quantity of pad 03 between artificial adjustment counterdie 02 and die holder 01, and not only labour intensity is large, and regulation time is long.General pad combination is: 2 × 50mm, 2 × 30mm, 2 × 20mm, and such as adjustment amount is 400mm, when monolateral adjustment amount is 200mm, monolateral adjustment amount can only be: 20mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, the specification that pad covers is less, and adjusts loaded down with trivial details.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of opening degree self-adjusting steel plate bending counterdie, solve existing lower die open degree and manually adjust loaded down with trivial details, the technical problem that labour intensity is large.
The present invention is achieved by the following technical solutions:
The self-adjusting steel plate bending counterdie of a kind of opening degree, comprise: be arranged on two counterdies on die holder, opening degree is left between two described counterdies, it is characterized in that: the lower surface of two described counterdies is processed into zigzag, the upper surface of described die holder is processed into the zigzag matched with described counterdie; Install between two described counterdies and described die holder by the lift cylinder group promoting contiguous block and oil cylinder group and form, the driving mechanism be made up of motor, tooth bar and driving contiguous block is also installed between two described counterdies and described die holder; Described lifting contiguous block and described counterdie bolted, described oil cylinder group is inserted in described die holder, the T connector of described oil cylinder group and the groove fit of described lifting contiguous block; Two described counterdies respectively driving contiguous block bolt described with two are connected, described motor is connected with described die holder, the gear shaft of described motor engages with two tooth bars be horizontally set on described die holder simultaneously, and the upper Plane Installation of described tooth bar has the projecting block of the fit depressions of the described driving contiguous block with two.
The present invention compared with prior art, because two are installed lift cylinder group and driving mechanism between counterdie and die holder: when two counterdies need adjustment opening degree, counterdie can lift by the pressurization of lift cylinder group, two counterdies are adjusted to required opening degree by driving mechanism action simultaneously, then lift cylinder group is oppositely pressurizeed, counterdie is fallen and is engaged with die holder, completes opening adjustment.
The present invention is used for bending steel plate, and have easy to adjust, quick, reliable, labor strength is little, the advantage that adjustable opening degree specification is many.

Detailed description of the invention
Exemplary embodiments of the present invention, will describe in detail by reference to the accompanying drawings.Be understood that the present invention can have various change in various embodiments, neither depart from protection scope of the present invention, explanation wherein and diagram are the use when explaining, and are not used to limit the present invention.
As shown in Figure 2,3, 4, the self-adjusting steel plate bending counterdie of a kind of opening degree, comprise: be arranged on two counterdies 1 on die holder 2, opening degree H is left between two described counterdies 1, the lower surface of two described counterdies 1 is processed into zigzag, and the upper surface of described die holder 2 is processed into the zigzag matched with described counterdie 1; Install between two described counterdies 1 and described die holder 2 by also installing between lift cylinder group 3, two described counterdies 1 and described die holder 2 of promoting that contiguous block 31 and oil cylinder group 32 form by motor 41, tooth bar 42 and the driving mechanism 4 that drives contiguous block 43 to form; Described lifting contiguous block 31 and described counterdie 1 bolted, described oil cylinder group 32 is inserted in described die holder 2, the T connector of described oil cylinder group 32 and the groove fit of described lifting contiguous block 31; Two described counterdies 1 respectively driving contiguous block 43 described with two are connected with bolt, described motor 41 is connected with described die holder 2, the gear shaft 411 of described motor 41 engages with two tooth bars 42 be horizontally set on described die holder 2 simultaneously, and the upper Plane Installation of described tooth bar 42 has the projecting block 421 of the fit depressions of the described driving contiguous block 43 with two.
Operation principle of the present invention is as follows:
1, the lower surface sawtooth of counterdie 1 is meshed with the upper surface sawtooth of die holder 2;
2, when two counterdies need adjustment opening degree, lift cylinder group 3 is pressurizeed, can by lifting contiguous block 31 jack-up by the T connector before oil cylinder 32, and counterdie 1 is lifted simultaneously;
3, driving mechanism 4 action, motor 41 drives tooth bar 42, and the projecting block 421 of tooth bar 42 drives and drives contiguous block 43 to move together, and two counterdies 1 are adjusted to required opening degree simultaneously;
4, lift cylinder group 3 is oppositely pressurizeed, and counterdie 1 is fallen and engaged with die holder 2, completes opening adjustment course of action.
Note: single opening adjustment amount can be determined by the size of sawtooth, opening adjustment amount can set arbitrarily and can not increase adjustment difficulty.
The present invention specifically can implement in a variety of forms and not depart from essence of the present invention, be to be understood that, above-described embodiment is not limited to aforesaid details, and should explain widely in claim limited range, therefore, fall into change in claim or its equivalent scope and remodeling all to should be claim and contained.
