Description

A kind of lamp stand upper die of bending machine of high strength

Technical field

The utility model relates to lamp stand bender technical field, more particularly, relates to a kind of lamp stand upper die of bending machine of high strength.

Background technology

Bender product is widely used in: electromechanics, panel beating, light industry, aviation, boats and ships, instrument, electrical equipment, stainless steel products, steel building and metallurgy industry etc., for shearing various steel plate, stainless steel, copper coin, aluminium sheet and nonmetallic materials sheet material, it can be converted into taper, arc, circle or square etc. product, can also design as requested and process special shape mould.

As everyone knows, light pole adopts steel to make mostly, and because light pole length is generally at 13 ~ 16m, curling shaping is worthless, can only adopt large-sized bender to process.Because the reason of framework own makes upper bolster produce small elastic deformation when bender loads, cause the angle of bending workpieces cannot ensure unanimously in total length direction.Meanwhile, the bending length of plate is very large on the impact of bending part precision, and the load that the longer requirement of plate bends is larger, also just becomes large, cause and guarantee that precision is more difficult in the distortion of the gradient and upper bolster that add equipment in man-hour.The usual way eliminating distortion arranges gradient compensation device on the table, meets the requirement on machining accuracy to workpiece by gradient compensation device; In addition, also have a kind of way to be that upper bolster is divided into multistage, multistage patrix is joined together to form a complete upper die body, this way can solve stress deformation along its length, but cannot remove the distortion of vertical direction when extruding up and down.Therefore, how designing a kind of lamp stand upper die of bending machine body, can solve the problem of vertical direction stress deformation, is a difficult problem for puzzlement lamp stand bender enterprise.

Through retrieval, Chinese Patent Application No.: 201220675478.0, the day for announcing: on July 17th, 2013, invention and created name is: a kind of bender combined type patrix, this application case discloses a kind of bender combined type patrix, and comprise cope match-plate pattern and little die head, cope match-plate pattern is arranged on slider of bender, little die head is arranged on cope match-plate pattern, and cope match-plate pattern is straight template or gooseneck template.The middle and lower part of straight template arranges a circular hole, circular hole is arranged little die head, and a boss is established in the lower end of straight template, and a little die head groove is established at the top of little die head, and the boss of little die head groove and described straight template is adaptive.The upper end of gooseneck template arranges link slot, and link slot is connected with slider of bender, and gooseneck template middle and lower part arranges little round platform, little round platform arranges little die head, a groove is established in gooseneck template lower end, and little Die top has a little die head boss, and the groove of little die head boss and described gooseneck template is adaptive.The upper die of bending machine structure that this application case provides is simple, and intensity difference, yielding for adding man-hour compared with machining long workpieces, affecting machining accuracy, requiring further improvement.

Detailed description of the invention

For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.

Embodiment 1

Composition graphs 1 and Fig. 2, the lamp stand upper die of bending machine of a kind of high strength of the present embodiment, this lamp stand upper die of bending machine is arranged in order by 8 pieces of upper die unit and forms, this upper die unit comprises lamp stand upper die body 1, upper bolster and reinforcement 4, wherein: upper bolster is made up of second connecting plate 304 on the Connection Block 302 of bottom, first connecting plate 303 at middle part and top.Offer pressing plate draw-in groove 305 in the side of the second connecting plate 304, the groove depth of this pressing plate draw-in groove 305 is 1/6 of the second connecting plate 304 thickness, by this pressing plate draw-in groove 305, upper die unit is connected with the slide block of lamp stand bender.In the present embodiment, the upper surface of lamp stand upper die body 1 offers rectangular channel, Connection Block 302 bottom upper bolster snaps in rectangular channel and the end face of Connection Block 302 is alignd with the end face of rectangular channel, be fixedly connected with lamp stand upper die body 1 to make upper bolster, first connecting plate 303 offers 4 window openings 301, the position that Connection Block 302 is corresponding with window opening 301 offers bolt hole, connecting bolt 2 is threaded with this bolt hole, and lamp stand upper die body 1 is fixed on upper bolster.

In the present embodiment, the thickness of the first connecting plate 303 is less than the thickness of the second connecting plate 304 and Connection Block 302, and this structure makes its force structure distributional class like the distribution of " work " word steel force structure.Moreover, the length of the first set connecting plate 303 is less than the length of the second connecting plate 304, and one end of the first connecting plate 303 flushes with one end of the second connecting plate 304, in the dead slot of first connecting plate 303 other end, be provided with reinforcement 4, and by set bolt 5, reinforcement 4 be fixed on the end face of the first connecting plate 303.When upper bolster is when vertical direction is stressed, its " work " word steel force structure makes pressure concentrate transmission by the first connecting plate 303, and be delivered to lamp stand upper die body 1 by Connection Block 302, because the lower surface of lamp stand upper die body 1 is set to the convex globoidal of rounding off, pressure can be made reasonably to spread out, be conducive to moulded section.In addition, when pressure is in more among a small circle, can first there is pressurized deformation in the first connecting plate 303, but this deformation is the deformation of vertical direction, less on machining accuracy impact, therefore, the length 0.8 ~ 1.6mm less of the height of the first connecting plate 303 of set reinforcement 4, this difference as the pre-made allowance of pressure distortion, the specifically length of reinforcement 4 1.0mm less of the height of the first connecting plate 303 in the present embodiment.When pressure continues to increase, first connecting plate 303 in the vertical direction may by bending, but reinforcement 4 now bears more multiple pressure power, this reinforcement 4 adopt the intensity of material higher than the strength of materials of the first connecting plate 303, make the high strength pressure that its in the vertical direction can offset or reduce suffered by the first connecting plate 303, effectively prevent the deformation of the first connecting plate 303 at vertical direction, be conducive to the raising of Workpiece Machining Accuracy.

The convex globoidal of the lamp stand upper die body 1 in the present embodiment comprises 5 arcwall faces, and the radius of curvature of each arcwall face constantly reduces from middle part to direction, both sides.Within the specific limits, the arcwall face that the convex globoidal of the lower surface of lamp stand upper die body 1 comprises is more, and its pressure distribution is more reasonable, and the lamp stand mould processed is also close to circle or ellipse.The present embodiment by arranging reinforcement 4 in the upper die unit of segmented lamp stand bender, and is optimized the structure of upper die unit, reduces the stress deformation of upper die unit, improves the machining accuracy of lamp stand bender.

Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
