Description

Technical Field

[0001] The invention relates to the technical field of plate shearing, in particular to a hydraulic swing-type shearing machine. Background Art

[0002] The swing shearing machine is a hydraulically driven shearing machine that relies on the rotation of the tool holder to achieve the shearing process. Compared with ordinary shearing machines, swing shearing machines mostly use oblique blade shearing. They are widely used due to their simple structure, low failure rate, high shearing efficiency and the fact that the sheet material does not bow, warp or twist after shearing. During the shearing process, as the tool holder rotates, the shearing angle and shearing gap of the swing shearing machine will change.

[0003] However, when the hydraulic swing shearing machine is in use, the sheared plates will collide with the discharge port under the action of gravity. The collision not only easily damages the plates, but also causes scratches at the discharge port. The discharge port creates greater resistance to the plates, causing the plates to accumulate at the discharge port, affecting the working efficiency of the shearing machine. Summary of the invention

[0008] Preferably, the movable sheet comprises a groove and a limiting column, the groove is provided at the upper end of the movable sheet, and the limiting column is fixedly mounted at one end of the movable sheet away from the elastic tube.

[0009] Preferably, the movable mechanism comprises an elastic strip, a movable ball and a movable member, the elastic strip is fixedly installed between two adjacent limiting columns, the movable ball is fixedly installed at the center of the elastic strip, and the movable member is arranged on the top of the contact plate.

[0010] Preferably, the movable part includes a rubber sleeve and an elastic membrane, the rubber sleeve is fixedly mounted on the bottom of the contact plate, the rubber sleeve is located inside the through hole at the top of the contact plate, a cavity is provided between the rubber sleeve and the elastic membrane, and the lower end of the rubber sleeve is connected to the outer surface of the movable ball.

[0011] Preferably, the movable sheet is movably installed on the inner side of the movable groove, the movable sheet is an elastic sheet, and the movable sheet is connected to the elastic strip through a limiting column.

[0012] The present invention provides a hydraulic swing shearing machine, which has the following beneficial effects:

[0013] (1) The hydraulic swing shearing machine is provided with a buffer mechanism and a movable mechanism to buffer the plates falling from the discharge port, thereby avoiding collision between the plates and the discharge port and allowing the plates to slide down smoothly from the discharge port, thereby preventing the plates from piling up at the discharge port and affecting the working efficiency of the shearing machine.

[0014] (2) In the hydraulic swing shearing machine, when the plate falls to the top of the contact plate, the plate generates pressure on the contact plate. The contact plate is pressed downward by the pressure and the elastic tube is squeezed downward. When the elastic tube is deformed, it drives the movable sheet to approach the resistance block. The movable sheet passes through the movable groove inside the resistance block and friction is generated between the movable sheet and the inner wall of the movable groove. The friction resistance slows down the deformation speed of the elastic tube, thereby reducing the impact force generated by the plate hitting the contact plate and avoiding damage to the contact plate.

[0015] (3) In the hydraulic swing shearing machine, when the movable plate moves in the movable groove, the groove on the outer side of the movable plate is constantly in contact with the notch of the movable groove, and the notch of the movable groove is opposite to the groove, so that the moving speed of the movable plate is further reduced, thereby enhancing the buffering effect of the buffer mechanism.

[0016] (4) In the hydraulic swing shearing machine, when the movable plate moves, it drives the elastic strip to move, and the elastic strip is deformed and recovers the deformation under the elastic restoring force. During the deformation and recovery process of the elastic strip, the movable ball at the center of the elastic strip moves accordingly. When the movable ball moves downward, it drives the rubber sleeve to move downward. The air between the rubber sleeve and the elastic membrane is brought to the lower end. At this time, the elastic membrane contracts downward, reducing the resistance to the plate, so that the processed plate can slide smoothly from the upper end of the contact plate, avoiding the accumulation of the plate on the contact plate and affecting the working efficiency of the device.

[0017] (5) In the hydraulic swing shearing machine, when the movable plate drives the elastic strip to move, the elastic strip is subjected to force to drive the movable ball to squeeze or stretch the rubber sleeve. The resistance generated by the deformation of the rubber sleeve is transmitted to the movable plate through the elastic strip, thereby slowing down the movement speed of the movable plate.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] See also Figure 1-6The present invention provides a technical solution: a hydraulic swing shearing machine, comprising a machine body 1, a workbench 2 is fixedly installed at the lower end of the front side of the machine body 1, a feed inlet 3 is opened at the center of the front side of the machine body 1, a discharge port 4 is opened at the center of the back side of the machine body 1, the discharge port 4 is inclined from the inner center of the machine body 1 to the lower end of the back side, a buffer mechanism 5 is arranged on the inner side of the discharge port 4, and a movable mechanism 6 is arranged on the upper end of the buffer mechanism 5.

[0028] The buffer mechanism 5 includes a fixed plate 51, a contact plate 52 and a buffer member 53. The fixed plate 51 is fixedly installed at the bottom of the discharge port 4, and the contact plate 52 is fixedly installed at the top of the fixed plate 51. A through hole is opened at the top of the contact plate 52. The processed plate falls on the contact plate 52 and slides down along the inclined contact plate 52. When the plate falls to the top of the contact plate 52, the plate exerts pressure on the contact plate 52. The contact plate 52 is pressed downward by the pressure to squeeze the elastic tube 531. The buffer member 53 is arranged at the bottom of the contact plate 52. The buffer member 53 includes an elastic tube 531, a movable sheet 532, a resistance block 533 and a movable groove 534, the elastic tube 531 is fixedly installed at the bottom of the contact plate 52, the outer surface of the elastic tube 531 is connected to the top of the fixed plate 51, the movable sheet 532 is fixedly installed on the outer surface of the elastic tube 531, the movable sheet 532 is movably installed on the inner side of the movable groove 534, the movable sheet 532 is an elastic sheet, and the movable sheet 532 is connected to the elastic strip 61 through a limiting column 5322, the movable sheet 532 includes a groove 5321 and a limiting column 5322, the groove 5321 is opened on the upper surface of the movable sheet 532 When the elastic tube 531 is deformed, it drives the movable sheet 532 to approach the resistance block 533. The movable sheet 532 passes through the movable groove 534 inside the resistance block 533. The movable sheet 532 and the inner wall of the movable groove 534 generate friction. The friction resistance slows down the deformation speed of the elastic tube 531, thereby weakening the impact force generated by the plate hitting the contact plate 52, thereby avoiding damage to the contact plate 52. The limiting column 5322 is fixedly installed on the end of the movable sheet 532 away from the elastic tube 531. When the movable sheet 532 moves, it drives the elastic strip 61 to move, and the elastic strip 61 is deformed. And it recovers its deformation under the elastic restoring force. During the deformation and recovery process of the elastic strip 61, the movable ball 62 in the center of the elastic strip 61 moves accordingly. The resistance block 533 is fixedly installed on the top of the fixed plate 51, and the movable groove 534 is opened on the front side of the resistance block 533. When the movable sheet 532 moves in the movable groove 534, the groove 5321 on the outside of the movable sheet 532 continuously contacts with the notch of the movable groove 534. The notch of the movable groove 534 is opposite to the groove 5321, so that the movement speed of the movable sheet 532 is further reduced, thereby enhancing the buffering effect of the buffer mechanism 5.

[0029] The movable mechanism 6 includes an elastic strip 61, a movable ball 62 and a movable member 63. The elastic strip 61 is fixedly installed between two adjacent limit columns 5322. When the movable sheet 532 drives the elastic strip 61 to move, the elastic strip 61 is forced to drive the movable ball 62 to squeeze or stretch the rubber sleeve 631. The resistance generated by the deformation of the rubber sleeve 631 is transmitted to the movable sheet 532 through the elastic strip 61, so that the moving speed of the movable sheet 532 is slowed down. The movable ball 62 is fixedly installed at the center of the elastic strip 61. When the movable ball 62 moves downward, it drives the rubber sleeve 631 to move downward. The space between the rubber sleeve 631 and the elastic membrane 632 The air is brought to the lower end, and the elastic membrane 632 contracts downward at this time, reducing the resistance to the plate, so that the processed plate can slide smoothly from the upper end of the contact plate 52, avoiding the accumulation of the plate on the contact plate 52 and affecting the working efficiency of the device. The movable part 63 is arranged on the top of the contact plate 52. The movable part 63 includes a rubber sleeve 631 and an elastic membrane 632. The rubber sleeve 631 is fixedly installed on the bottom of the contact plate 52. The rubber sleeve 631 is located on the inner side of the through hole at the top of the contact plate 52. A cavity is provided between the rubber sleeve 631 and the elastic membrane 632. The lower end of the rubber sleeve 631 is connected to the outer surface of the movable ball 62.

[0030] When in use, turn on the device switch, place the sheet to be sheared on the upper end of the workbench 2, push it into the inner side of the machine body 1 from the feed port 3, the sheet is sheared on the inner side of the machine body 1, and the processed sheet falls on the contact plate 52, and slides down along the inclined contact plate 52. When the sheet falls to the top of the contact plate 52, the sheet exerts pressure on the contact plate 52, and the contact plate 52 is pressed downward by the pressure to squeeze the elastic tube 531. When the elastic tube 531 is deformed, it drives the movable sheet 532 to approach the resistance block 533, and the movable sheet 532 passes through the inner side of the resistance block 533. The movable groove 534 generates friction between the movable sheet 532 and the inner wall of the movable groove 534. The friction resistance slows down the deformation speed of the elastic tube 531, thereby reducing the impact force generated by the plate hitting the contact plate 52, thereby avoiding damage to the contact plate 52. When the movable sheet 532 moves in the movable groove 534, the groove 5321 on the outer side of the movable sheet 532 constantly contacts the notch of the movable groove 534. The notch of the movable groove 534 is opposite to the groove 5321, so that the moving speed of the movable sheet 532 is further reduced, thereby enhancing the buffering effect of the buffer mechanism 5.

[0031] In the initial state, the elastic membrane 632 protrudes from the contact plate 52. When the cut sheet falls on the surface of the contact plate 52, the elastic membrane 632 can cushion the cut sheet to a certain extent. When the cut sheet is completely pressed onto the surface of the contact plate 52, the movable sheet 532 moves, driving the elastic strip 61 to move. The elastic strip 61 is deformed and moves downward. The movable ball 62 at the center of the elastic strip 61 moves accordingly. When the movable ball 62 moves downward with the elastic strip 61, it drives the rubber sleeve 631 to move downward. The air between the rubber sleeve 631 and the elastic membrane 632 is brought to the lower end. At this time, The elastic membrane 632 shrinks downward until the top surface of the elastic membrane 632 is lower than the surface of the contact plate 52, thereby no longer hindering the sheared sheet material, reducing the resistance to the sheet material, and allowing the processed sheet material to slide smoothly from the upper end of the contact plate 52, thereby avoiding the accumulation of sheets on the contact plate 52 and affecting the working efficiency of the device. When the movable sheet 532 drives the elastic strip 61 to move, the elastic strip 61 is forced to drive the movable ball 62 to squeeze or stretch the rubber sleeve 631. The resistance generated by the deformation of the rubber sleeve 631 is transmitted to the movable sheet 532 through the elastic strip 61, which can further slow down the movement speed of the movable sheet 532.
