Description
Technical field:
The present invention relates to the vegetable fibre stampings, be specifically related to vegetable fibre compacting pallet and specialized equipment thereof.
Background technology:
At present, in goods storage, stacking, transportation, pallet has become one of main instrument.Vegetable fibre wherein (comprising agricultural crop straw) pallet has low cost simultaneously, hangs down advantages such as polluting, need not to fumigate processing because of it can realize recirculation, utilization, the percent recovery can reach 100% again, enjoys the market favor.But plant fiber tray is because the big particularity of volume change in poor, the mold process of raw material flowing power, adopt mould pressing process such as single way stempressing forming process on the universal, it is irregular that ubiquity compacted density, especially the junction of feet and plate, weak link especially, moulding in the production, demoulding difficulty is big, breakage rate is high, production efficiency low (need add material), and the manufactured product bearing capacity is little, can not satisfy operating needs.In the past few years, the inventor has submitted multinomial patent of invention to, with two-way pressure-formed method and special-purpose press device, successful solution the problems referred to above.But the patent of submitting to before the inventor, also only be to be plate above having solved, be provided with the production of the plant fiber tray of split type feet below, pallet for special shape, be the Contiuum type feet or be provided with between the plate up and down and be provided with reinforced rib in feet or the feet chamber and be used for heavily stressed pallet as plate bottom, use existing technical scheme, still be difficult to produce acceptable product.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of plant fiber heavy-duty tray, will provide this tray bidirectional pressure-formed particular manufacturing craft simultaneously, and pressure-formed pallet has that the shaped article compacting is even, intensity is high, is suitable for the transhipment of heavy goods.
The present invention is achieved through the following technical solutions:
Plant fiber heavy-duty tray comprises plate, is arranged at the feet of plate bottom, and described feet transversal surface is rectangular, or the middle part of transversal surface is rectangular, the two ends semicircular in shape, and feet is provided with reinforced rib in the chamber.The reinforced rib of feet transversal surface is in-line or is criss-cross or is groined type.
The two-way pressure-formed particular manufacturing craft of plant fiber heavy-duty tray, comprise former, upper punch, bottom punch, with the core bar that bottom punch flexibly connects, also comprise engine installation; The feet die cavity transversal surface of described former is rectangular, or the middle part of transversal surface is rectangle, two ends semicircular in shape, the stamping head of bottom punch and the feet die cavity of former coupling; Described stamping head is provided with the hole that passes of two core bars at least, and the set hole of core bar and stamping head is a free-running fit, and core bar moves up and down in the hole.
The bottom of every core bar is provided with a locating plate, or the bottom of at least two core bars is provided with a locating plate, after the two ends of described locating plate pass from the set slotted eye of the stamping head of bottom punch and the connecting panel between the stamping seat, be fixed on the bottom half of former, or be connected in the bottom half of former by stage clip.
It is rectangle, two ends semicircular in shape that the present invention becomes the middle part of rectangle or transversal surface with the cross-sectional design of the feet of pallet, be provided with reinforced rib in the chamber of feet, feet is arranged side by side, extend to the other end of plate from an end of plate, improve the bearing capacity of feet greatly, be applicable to the transhipment of heavy goods such as mechanical equipment.
Description of drawings:
Fig. 1 is the plant fiber heavy-duty tray schematic perspective view.
Fig. 2 is the vertical partial schematic sectional view of particular manufacturing craft (many core bars is arranged on the locating plate).
Fig. 3 is bottom punch among Fig. 2 and stamping head thereof and the core bar schematic perspective view that cooperatively interacts.
Fig. 4 is the vertical partial schematic sectional view of particular manufacturing craft (every core bar is provided with a locating plate).
The specific embodiment:
As shown in Figure 1, plant fiber heavy-duty tray, comprise plate 6, be arranged at the feet 7 of plate 6 bottoms, rectangular, the two ends semicircular in shape in the middle part of described feet 7 transversal surfaces, three feets 7 are arranged side by side, extend to the other end of plate 6 from an end of plate 6, and feet is provided with reinforced rib 8 in 7 chambeies, the bottom of described reinforced rib 8 and feet 7 is on a plane (bearing capacity is big), and the reinforced rib 8 of feet 7 transversal surfaces is in-line.
As shown in Figure 2, the two-way pressure-formed particular manufacturing craft of plant fiber heavy-duty tray, comprise former 1, upper punch 2, bottom punch 3, with the core bar 4 that bottom punch 3 flexibly connects, also comprise engine installation.The middle part of feet die cavity 11 transversal surfaces of former 1 is rectangular, two ends semicircular in shape (diagram is not provided), the stamping head 31 of bottom punch 3 and the feet die cavity of former 11 couplings.Shown in Fig. 2,3, what described stamping head 31 was provided with four core bars 4 passes hole 32, and the described hole 32 that passes is cut off 34 by in-line and separates, and core bar 4 and stamping head 31 set holes 32 are bearing fit, and core bar 4 can move up and down in hole 32.Still shown in Fig. 2,3, four core bars 4 are arranged on the adapter plate 41.After locating plate 41 two ends of core bar 4 pass from the set slotted eye of the stamping head of bottom punch and the connecting panel between the stamping seat 35, (locating plate 41 also can be provided with engine installation to be connected in the bottom half of former 1 by stage clip 42, realize moving up and down by the engine installation push-and-pull, be provided with so in this way, unit then can not move, and can't realize that two units work by turns).
As shown in Figure 4, the bottom of every core bar 4 is provided with a locating plate 41, is connected with core bar after 41 need of locating plate rotate an angle of 90 degrees as shown in Figure 2, and the set slotted eye of the connecting panel between stamping head and the stamping seat also needs to be provided with behind the corresponding rotation an angle of 90 degrees.All the other are implemented as embodiment 1.
When suppressing pallet with the present invention, as routine: former is after charging under the vibrational state finishes, use stamping compacting plate earlier, again with engine installation jack-up bottom punch compacting feet, when the stamping seat 33 of bottom punch arrives to core bar locating plate 41, this moment, the stamping head equated that with the distance of core bar termination identity distance separation disc plate lower surface both make progress synchronously apart from feet bottom surface desired location, until feet being pressed (core bar termination face is parallel with the plate lower surface).Compacting is during feet, and stamping head 31 peripheries of bottom punch and feet periphery coincide and with its compacting, cut off 34 with the feet chamber in reinforced rib identical and with its compacting.During the demoulding such as conventional method.
