Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
The upper part of the molding tray M shown in fig. 8 and 9 is a bearing surface, and the lower part of the molding tray M is provided with a plurality of supporting legs M1 formed by molding (the bottom end of the molding tray in the figure is provided with 9 supporting legs, and the bearing surface of the molding tray M is used for supporting the transported goods.
The utility model provides a mould pressing tray rolling test machine, which comprises a frame 4 standing on a base plate 1 (the base plate is fixed on the ground) and a controller; the frame is formed by a support framework 2 and a sealing plate 20 coated on the surface of the support framework.
The rack is provided with a test box which can contain the mould pressing tray and can rotate around a horizontal axis and a power mechanism which drives the test box to rotate.
The test box is cylindrical and the inner cavity of the test box is larger than the box body of the mould pressing tray (the diameter of the inner cavity is preferably 1.8 m); the test chamber is rotatably positioned at the upper part of the frame by a horizontally arranged rotating shaft 16, which is driven by a motor 19 (recommended speed reducing motor); and a pair of (two) supporting rollers 21 support the two sides of the lower part of the suspended test box, so that the rotation stability of the test box can be still kept when the test box bears the load, and the abrasion and the deformation of the horizontal rotating shaft (16) caused by the long-term load operation of the test box are prevented. The supporting roller is positioned on a fixed shaft through a bearing, and the fixed shaft is fixed on the rack and is arranged in parallel with the rotating shaft.
The test chamber is a chamber body (preferably made of steel) with an inner cavity, and is formed in a cylindrical chamber body shape by a back plate 15, a wall plate 13 (generally formed by welding) surrounding a circumferential surface and a chamber door 9 arranged on the front end surface of the test chamber. The diameter of the cavity is larger than the length of the diagonal line (diagonal line of the horizontal projection of fig. 8) of the molding tray, and the height of the axis of the cavity of the test chamber (dimension perpendicular to the paper surface in fig. 6) is larger than the height of the molding tray (dimension in the up-down direction of fig. 8). The inner circumferential wall of the test box is provided with a plurality of support pads 10 (uniformly distributed along the circumferential direction) so that the mould pressing tray in the test box can rotate along with the test box when rotating, and the wall plate is impacted after weightlessness occurs, thereby realizing the detection of the angle impact strength item. As can be seen from fig. 5 and 7: six support pads are uniformly distributed on the wall surface of the whole inner circumference; when the test box works (the rotation direction of the test box is shown by an arrow S), the supporting pad can block and support one corner at the lower part of the mould pressing tray (see figure 8), so that the mould pressing tray rotates along with the test box until the upper part of the mould pressing tray inclines to lose the gravity center, and the other adjacent corner M2 at the upper part of the mould pressing tray collides with the wall surface; the impact angle of the tray rotates to the lower part along with the test box, another adjacent angle at the lower part of the tray is then blocked and supported by another supporting cushion on the inner wall, the rotation is repeated, the gravity center and the impact are lost, and the cycle is repeated in sequence. And observing the angle impact condition, and finishing the detection work when the angle is damaged or the specified impact times are reached. In addition, the surface of the supporting pad is further coated with a soft protective layer 10-1 (preferably a rubber layer) to prevent the molded tray from being damaged when impacting the supporting pad, so that the detection result is invalid.
The box door is a split double door so as to be convenient for taking the mould pressing tray out of and putting the mould pressing tray into the test box; the box door is preferably made of transparent materials with certain strength, so that the test condition can be observed in real time conveniently. The door is provided with a lockset 8 (or a buckle or an outsourcing part) for locking the door, so that the condition that the mould pressing tray falls out due to the fact that the door is knocked open in the detection process is prevented, and the detection safety is ensured. As shown in fig. 6, for installation convenience, the shape of each box door needs to be as close to a rectangle as possible, so that an upper sharp corner edge, a lower sharp corner edge and a circular arc edge between the two sharp corner edges are cut off from a semicircle; correspondingly, four arc-shaped baffles 12 with the size corresponding to the arc edge are symmetrically fixed (preferably welded and fixed) on the part of the test box corresponding to the box door; the vertical edges of the left circular arc baffle and the right circular arc baffle are respectively fixed with a box door through hinges (the four circular arc baffles and the split double doors complement each other to form a complete circle, and the diameter of the circle is the same as that of the test box).
In the power mechanism, a rotating shaft 16 can be rotatably and horizontally positioned at the top end of the rack through a bearing; the motor 19 is installed on the top end of the frame, the motor shaft is fixed with one end of the rotating shaft through the coupler, the connecting disc 6 is fixed at the other end of the rotating shaft, and the disc surface of the connecting disc is perpendicular to the axis of the rotating shaft (the disc surface of the connecting disc is directly attached to the back of the test box and is fixedly connected with the back plate at the back of the test box through a fastener).
The motor is communicated with the controller through wired or wireless equipment to realize control over the detection process; the controller is mounted on the operation control board 7.
Furthermore, the utility model discloses a guardrail 3 that still adopts the baffle to enclose around can keep apart the staff when detecting, ensures safety.
The utility model discloses a theory of operation is: before detection, opening a box door, vertically placing a mould pressing tray M into a test box, closing the box door and then locking; then the motor is started, the test box rotates slowly around the horizontal axis, and the mould pressing tray in a natural state in the box body rotates along with the rotation of the box body and can also slide. When the tray is blocked by the supporting cushion and supports the bottom tray corner, the tray completely rotates along with the box body, then the gravity center is lost, and the upper corner of the tray hits the wall part in the inner circumferential direction of the test box; and after the tray corner is observed to be damaged or the specified impact times are reached, stopping the motor from rotating and opening the box door. The tray corner is damaged, and the test is finished; when the specified impact times are reached and the tray angle is not damaged, the front and back sides of the molded tray are reversed by 180 degrees, then the molded tray is vertically placed into the test box, the box door is closed and locked, then the motor is started, and the test is started according to the method. And after the tray corners are observed to be damaged or the specified impact times are reached, stopping the motor from rotating, opening the box door, taking out the die pressing tray, and checking the impact damage degree of the tray corners of the die pressing tray to obtain the detection result of the rolling detection items.
