The lower bearing frame is a grid-shaped rectangular frame body formed by criss-cross longitudinal rib plates and transverse rib plates, two connecting lugs are respectively overhung out of the planes of the longitudinal rib plates on the two outer sides, and a vertical through hole for penetrating and sleeving the stand column is arranged in each connecting lug. The lower bearing frame, the upright post and the upper bearing frame are together constructed into a frame of the cold press, are used for bearing the assembly platform and are used as a bearing support for cold pressing of the plates.
The upper bearing frame is a grid-shaped rectangular frame body formed by crossing longitudinal rib plates and transverse rib plates, two connecting lugs are respectively overhung out of the planes of the longitudinal rib plates on the two outer sides, and a vertical through hole for penetrating and sleeving the upright column is arranged in each connecting lug. The upper bearing frame is used for fixedly connecting the pressurizing oil cylinder and the quick oil cylinder while forming a frame.
The stand is the cylindrical body of rod that has the external screw thread for the upper and lower relative engaging lug of cross-under bearing frame and lower bearing frame, and fasten the upper and lower of each engaging lug through the nut, will bear frame and lower bearing frame location on four stands.
The movable pressing plate is positioned between the upper bearing frame and the lower bearing frame and comprises a grid-shaped rectangular frame body, a top plate fixedly connected to the top surface of the grid-shaped rectangular frame body and a bottom plate fixedly connected to the bottom surface of the grid-shaped rectangular frame body. The movable pressing plate is used as a pressing part of the cold press and is used for pressing and forming the plate blank placed on the assembly platform.
The cylinder body of the pressurizing oil cylinder is fixedly connected to the upper bearing frame, and the piston rod end of the pressurizing oil cylinder is connected to the movable pressing plate so as to control the pressing operation of the movable pressing plate.
The cylinder body of the quick oil cylinder is fixedly connected to the center of the upper bearing frame, and the piston rod end of the quick oil cylinder is connected to the movable pressing plate, so that the quick closing of the movable pressing plate and the quick lifting of the movable pressing plate after the pressing process of the pressing plate are achieved during cold pressing of the plywood.
Furthermore, a transverse rib plate forming the main beam is arranged in the lower bearing frame, the two left and right opposite connecting lugs are positioned at the extending ends of the transverse rib plate forming the main beam in the lower bearing frame, and the height of the connecting lugs is half of the height of the transverse rib plate forming the main beam.
Furthermore, the cross rib plate forming the main beam in the lower bearing frame is a single-limb steel plate, and the connecting lug is a steel sleeve with a through hole and welded on the single-limb steel plate. The transverse rib plate forming the main beam in the lower support frame can also be a double-limb steel plate, the extending end of the double-limb steel plate is welded with a connecting rib, the connecting rib and the extending end of the double-limb steel plate form a vertical through hole penetrating the upright column, and a connecting lug on the lower support frame is formed.
Furthermore, in the lower bearing frame, the upper edge of the longitudinal rib plate is higher than the upper edge of the transverse rib plate so as to be used as a fulcrum for supporting the assembly platform and a guide rail for the assembly platform to enter and exit the cold press.
Furthermore, a transverse rib plate forming the main beam is arranged in the upper bearing frame, two left and right opposite connecting lugs are positioned at the extending ends of the transverse rib plate forming the main beam in the upper bearing frame, and the height of the connecting lugs is half of the height of the transverse rib plate forming the main beam.
Furthermore, the cross rib plate forming the main beam in the upper bearing frame is a single-limb steel plate, and the connecting lug is a steel sleeve with a through hole and welded on the single-limb steel plate. The transverse rib plate forming the main beam in the upper support frame can also be a double-limb steel plate, the extending end of the double-limb steel plate is welded with a connecting rib, the connecting rib and the extending end of the double-limb steel plate form a vertical through hole penetrating the upright column, and a connecting lug on the upper support frame is formed.
Furthermore, the connecting lugs are positioned at the positions above or below the middle waist line of the cross rib plate forming the main beam, namely the connecting lugs on two sides of the upper bearing frame and the lower bearing frame are limited by the middle waist line of the cross rib plate forming the main beam, either the left side and the right side are both on the upper side, either the left side and the right side are both on the lower side, or one of the left side and the right side is both on the upper side and one of the left side and the right side is the lower side.
Furthermore, the connecting lugs at the butt joint of the adjacent upper bearing frames are in staggered lap joint arrangement, the connecting lugs at the butt joint of the adjacent lower bearing frames are in staggered lap joint arrangement, and the cold press unit with the multi-span connecting rows is formed after the upright columns arranged at the butt joint are in cross joint and fixed.
The connecting lugs on the two sides of the upper bearing frame and the lower bearing frame can be made into a form that two sides are arranged on the upper side, or two sides are arranged on the lower side, or one side is arranged on the upper side and the other side is arranged on the lower side, so that all the connecting lugs can be in an up-down lap joint form of a left connecting lug and a right connecting lug at the adjacent cross joint part when the connecting spans are combined, and the through holes are fixedly connected through the upright posts to form the row cold press unit. The difference is that the connecting lugs at the two sides of the upper bearing frame and the lower bearing frame are made into a mode that one side is up and the other side is down, and the number of standard modules of the upper bearing frame and the lower bearing frame is minimum. When the connecting lugs on the two sides of the upper bearing frame and the lower bearing frame are made to be arranged with two sides on the upper side or two sides on the lower side, the standard modules of the upper bearing frame and the lower bearing frame are two, thus not only increasing the processing workload, but also increasing the installation workload.
The cold press adopts a modular design, can be connected into a row cold press unit in a splicing way, and has the characteristics of material saving, easy processing, convenient transportation, easy installation and debugging, flexible use, field saving and the like. The invention is different from the overall, single span and welding type structures of most traditional hot presses, and can greatly reduce the comprehensive cost of the press in the aspects of material consumption, processing, transportation, installation, debugging and the like. The cold press can be assembled in a single span mode or in a multi-span continuous mode. The upper bearing frame and the lower bearing frame are fixedly connected with the upright posts through connecting lugs extending out of the main beams to form a frame of the cold press. When the two spans are combined, the upper and lower lap joints of the connecting lugs are matched, so that the cold presses can be arranged in a row to form a cold press unit, and therefore, simple, convenient and quick scale expansion can be realized to organize high-efficiency production.
The cold press of the invention has the following characteristics:
1. the traditional welding mode of the whole machine is changed into a plurality of standard modularized processing and assembling modes.
2. The structure of the upper and lower lap joints of the connecting lugs at the two ends of the main beams of the upper and lower bearing frames can conveniently optimize the single span mode of the traditional press into the mode of multi-span row assembly.
3. The upright posts adopt a screw rod structure, and modular machine parts are fixed through nuts, so that convenience is provided for assembly of the rows and the groups.
4. The main beam direction of the upper bearing frame and the lower bearing frame is the plate width direction, the beam span length is reduced by half, and the material consumption can be greatly reduced.
5. The four upright posts are located in the plate span range of 1/2-2/3 in the plate length direction, so that the stress of the lower bearing frame and the movable pressing plate is in a single span beam state with cantilevers at two ends, and the material consumption of equipment is effectively reduced.
The cold press is combined in a row along the width direction of the press, and the stress span is only half of the long span, so that high-tonnage large-pressure pressurization can be realized on the premise of saving materials; because the row combination is carried out along the width direction of the press, compared with the span of the length direction of the press, the walking distance from the assembly to the press can be shortened by times, so that the pressurizing closing time can be shortened. The size of the opening gear can be conveniently adjusted by adopting the fastening connection mode of matching the upright post and the nut, and the large opening gear is obtained without obstacles. This is because the number of presses required can be achieved at minimal cost due to the modular inline press practice.
For the hot pressing process, when assembling, a separation base plate is not needed to be arranged between the adjacent plywood, the plywood is directly aligned and stacked together up and down, and the plywood is pushed into a prepressing machine for prepressing. For a board width of 4 x 8 feet, the pressure is increased to 100-300 tons, the pressure maintaining time is 60-90 minutes, or even longer, so as to ensure complete shaping, and then the board is transferred to a hot press for hot pressing. During hot pressing, the stacked and pre-pressed plates are separated one by one and then placed between each layer of hot pressing package of the hot press, and only one plate is placed on one layer. The pressing time of each furnace is 10-15 minutes by taking a thick plate of 18mm as an example.
The processing process for producing the plywood rough board by adopting the cold pressing process of the cold press is similar to the prepressing procedure in the hot pressing process, and the difference lies in that the pressure of the cold pressing process is larger: for a 4 × 8 feet plate, the pressure needs to be 300-600 tons, and the pressure-maintaining time is 30-60 minutes. The cold pressing process adopted by the invention not only shortens the pressure maintaining time, but also omits the hot pressing procedure. Therefore, compared with a hot pressing process, the cold pressing process can improve the production efficiency, greatly reduce the heat energy consumption and meet the development requirements of energy conservation and environmental protection.
The cold press of the present invention has the following advantages:
1. the adjacent spans share the stress column, and the upright column adopts a cylindrical form, is the optimal section form of the axial tension member, is more efficient than a wide plate form, saves materials, reduces machining amount, and can obviously reduce the manufacturing cost of equipment.
2. The modular assembly design decomposes the whole main frame of the press into four components, namely an upright post, a lower bearing frame, a movable pressing plate and an upper bearing frame, and each component is of a standard structure, so that the quantitative production can be realized, the processing difficulty of equipment can be obviously reduced, the processing amount is reduced, and the processing cost is reduced.
3. The modular assembly design, each component classification packing, the conveying efficiency and the convenience are much better than the complete machine transportation.
4. When the whole machine is assembled, the screw rod and the nut are connected in a fastening mode, so that the assembling time can be greatly shortened.
5. Due to the adoption of the screw rod type connection, the opening size of the cold press can be adjusted according to the requirement, so that the opening requirements of users on different stages of the cold press can be met.
6. Because the four-column type support is adopted, the landing point of the cold press can be only arranged at the upright post, and the cold press has a leveling function, so that the requirements on the site and the flatness when the cold press is installed in place are greatly reduced.
7. Because the left and right ends of the joints of the upper and lower bearing frames and the upright post bolts are in an upper and lower tongue-and-groove relationship, the cross sections are the same and have the same height, the vertical column has the advantages that: first, the left and right joints have equal strength requirements (the equal strength requirements are all general requirements related to mechanical performance components); secondly, after the row is assembled, the elevations of the upper and lower bearing frames of each span are the same, and the leveling is easy to realize; the hydraulic system is favorable for arrangement, and other production links are convenient to link.
8. The row direction of the row-connected press is in the short side direction of the press, and the advantages are that: firstly, the span of a main beam at the position of the hydraulic oil cylinder is reduced, so that the material consumption of the main beam is greatly reduced; secondly, the arrangement of the upright columns in the length direction of the press is within the range of 1/2-2/3 of the span, so that the materials used for the upper and lower bearing frames and the middle press table are the least on the premise of meeting the requirements on rigidity and strength.
In conclusion, the standard modular design concept of the cold press is completely different from the traditional press, and the press has the advantages of material saving, easiness in processing, convenience in transportation, easiness in installation and debugging, flexibility in use, field saving and the like. The innovative effects can generate practical application value in the future industrial upgrading process.
