Abstract
The invention provides a stress relief cold press, which comprises a lower press plate (1), an upper press plate (2), a control box (3), a hydraulic rod (4) and a hydraulic oil cylinder (5), wherein an auxiliary hydraulic oil cylinder (6) is arranged between the hydraulic rod (4) and the upper press plate (2), and a pressure sensor (8) is arranged on a contact surface of the press plate and a plate. The stress relief cold press has the advantage that the sensor on the press plate can timely transfer the stress condition of each part of the plate to a control box, the control box adjusts the hydraulic rod according to the stress condition of the plate, and then the stress on the plate is uniform, so the conditions of warpage and deformation of the plate due to stress are eliminated, and the yield of the pressed plate is improved.
Description
Technical field
The invention belongs to woodworking machinery field, relate in particular to a kind of stress and eliminate cold press.
Background technology
Cold press is a kind of machinery for pressing sheet material conventional in carpenter field.But a problem of existing cold press is, if sheet material is because there is stress in the factors such as structure, during compacting, can not adjust for stressing conditions, the sheet material suppressing there will be warpage, and this warpage cannot be remedied in time after cold press discharges, cause sheet deformation and defective.Therefore be necessary to adjust in sheet material pressing process, eliminate sheet material stress, to reduce the disqualification rate of pressed sheet.
Summary of the invention
The present invention has developed a kind of Novel cold press that can eliminate stress in pressing process, has effectively solved the problems referred to above.The technical solution adopted in the present invention is as follows:
A kind of stress is eliminated cold press, comprise lower platen 1, top board 2, control cabinet 3, hydraulic stem 4 and hydraulic jack 5, it is characterized in that, secondary hydraulic jack 6 is also installed between hydraulic stem 4 and top board 2, and pressure inductor 8 is installed on the contact-making surface of pressing plate and sheet material.During pressed sheet, pressure inductor is transformed into signal by the pressure of institute's sensing and passes to control cabinet, and control cabinet is adjusted each hydraulic stem according to the stressing conditions of sheet material.In the ordinary course of things, the warpage of sheet material appears at four angles, when certain angle stressed abnormal, by the synergy of master hydraulic bar and secondary hydraulic jack, increase or reduce the stressed of this corner, make the stressed even of whole sheet material, thereby realize the elimination of stress, obtain qualified sheet material.
For reducing the rate of breakdown of inductor in the harsh working environment of cold press, described pressure inductor 8 preferably adopts circular cone type mechanical pressure inductor, and is arranged on out in the hole 7 on pressing plate, so that the protection to pressure inductor to be provided.
At stress of the present invention, eliminate in cold press, the pressing plate that pressure inductor 8 is installed can be top board, also can be lower platen, but described pressure inductor 8 is preferably arranged on the contact-making surface of top board 2 and sheet material, it is clean that the hole that inductor is installed on pressing plate is like this easy to keep, the interference that inductor is subject to is less, can keep for a long time sensitive state.
Preferably, pressure inductor 8 has a plurality of, is distributed in four angles and the centre of top board 2, to obtain the comprehensive measurement to sheet material.
Beneficial effect: while adopting stress of the present invention to eliminate cold press, by the analysis to sheet material stressing conditions in sheet material pressing process, adjust in real time pressing plate, can eliminate in time the stress of sheet material, reduce the warpage that pressing plate discharges rear sheet material, improve the qualification rate of pressed sheet.
Accompanying drawing explanation
Fig. 1 is the general structure schematic diagram that stress of the present invention is eliminated cold press.
Fig. 2 is the structural representation that stress of the present invention is eliminated the secondary hydraulic jack of cold press.
Fig. 3 is the structural representation that stress of the present invention is eliminated the pressing plate of cold press.
In the drawings: 1 lower platen; 2 top boards; 3 control cabinets; 4 hydraulic stems; 5 hydraulic jacks; 6 secondary hydraulic jacks; 7 holes; 8 pressure inductors.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention in detail.
Referring to Fig. 1, stress of the present invention is eliminated cold press and is comprised lower platen 1, top board 2, control cabinet 3, hydraulic stem 4 and hydraulic jack 5, and secondary hydraulic jack 6 is also installed between hydraulic stem 4 and top board 2, pressure inductor 8 is installed on the contact-making surface of pressing plate and sheet material.
Fig. 2 shows the structure of secondary hydraulic jack 6 while observing from the side.Secondary hydraulic jack 6 is arranged on the below of master hydraulic bar 4, and the both sides that two hydraulic stems are connected to top board are stretched out in secondary hydraulic jack 6 belows.Hydraulic jack 5 and secondary hydraulic jack 6 all controlled case 3 are controlled, and when therefore hydraulic jack 5 and secondary hydraulic jack 6 act synergistically under the control of control cabinet 3, can realize top board 2 in the inclination of all directions, and fine setting institute pressed sheet is stressed all directions.The warpage of sheet material is generally to occur on one or more angles, increases or alleviate the pressure in respective corners, can eliminate the stress of sheet material corresponding site, improves this warpage situation.
The stressing conditions of sheet material is that the pressure inductor 8 by being arranged on pressing plate obtains.Pressure inductor 8 is mounted on the face that pressing plate contacts with sheet material, and as shown in Figure 3, pressure inductor 8 can be installed a plurality of on pressing plate, to obtain the comprehensive measurement to sheet material.The distribution of pressure inductor 8 preferably as shown in Figure 3, has distribution at four angles, also every a segment distance, distributes one in addition on the major axis of pressing plate, in the situation that pressing plate is larger, also can distribute a plurality of on minor axis.
At stress of the present invention, eliminate in cold press, the pressing plate that pressure inductor 8 is installed can be top board, also can be lower platen, but described pressure inductor 8 is preferably arranged on the contact-making surface of top board 2 and sheet material, it is clean that the hole that inductor is installed on pressing plate is like this easy to keep, the interference that inductor is subject to is less, can keep for a long time sensitive state.
By reference to the accompanying drawings embodiments of the present invention are described in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken possessing at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
