Description

Technical Field

[0001] The utility model relates to the field of plate shearing machines, in particular to a hydraulic swing type plate shearing machine. Background Art

[0002] As a commonly used metal cutting equipment, shearing machine is widely used in machinery manufacturing, construction, automobile and other industries. For example, the hydraulic swing shearing machine with patent number CN212551956U adopts a flywheel structure to realize the reciprocating motion of the knife body, thereby effectively protecting the knife and effectively solving the problems mentioned in the background technology.

[0003] However, through research and analysis, it was found that when this type of shearing machine shears the plate, the operator is usually required to place the plate to be sheared on the beam, then push the plate to the appropriate position, and then start the motor through an external switch to drive the knife body to shear the plate. This method requires manual adjustment of the plate position each time the plate is sheared, which has low operating efficiency and is not convenient for mass production. In addition, manual adjustment has certain errors, which is not conducive to fixed-length cutting of the plate. Therefore, it is necessary to improve the shortcomings and defects of the existing technology. Utility Model Content

The shearing plate 5 is slidably connected to the vertical guide groove 12, and two parallel triangular supports 6 are fixedly connected to the frame 1 in the direction away from the flat plate 11, and a lateral slat 7 is fixedly connected to the upper side of the triangular support 6. A guide rail 1 71 and a guide rail 2 72 are sequentially arranged on the lateral slat 7 from top to bottom, and a slider 8 is slidably connected to the guide rail 1 71, and a corresponding sensor 10 is fixedly installed on the inner surface of the slider 8, and a receiving plate 9 is inserted between the two guide rails 2 72.

[0026] A control panel 101 is fixedly mounted on the outer surface of the frame 1, and the control panel 101 is electrically connected to the hydraulic telescopic rod 1 2, the hydraulic shearing mechanism 4 and the corresponding sensor 10 respectively.

[0027] A telescopic rod 31 is provided on the pressing mechanism 3, the top of the telescopic rod 31 is fixedly connected to the lower side of the lower pressure plate 21, the lower side of the telescopic rod 31 is fixedly connected to a mounting block 32, a roller 33 is rotatably connected inside the mounting block 32, and a spring 34 is sleeved on the axial outer side of the telescopic rod 31, and the spring 34 is located between the lower pressure plate 21 and the mounting block 32.

[0028] There are two groups of hydraulic shearing mechanisms 4 on both sides of the plate conveying direction. The hydraulic shearing mechanism 4 is provided with a pull rod 41 and a hydraulic telescopic rod 43. The pull rod 41 is slidably connected in the vertical guide groove 12, and the hydraulic telescopic rod 43 is rotatably connected to the lower side of the flat plate 11. The lower part of the pull rod 41 is rotatably connected to the transmission rod 44 through the push-pull rod 42. The connection parts between the transmission rod 44 and the push-pull rod 42 and the hydraulic telescopic rod 43 are all hinged, and a connecting rod 45 is rotatably connected between the two transmission rods 44.

[0029] An upper plate 50 is disposed on the shear plate 5 , and a shearing blade head 52 is inserted into the lower part of the upper plate 50 through a mounting groove 51 . The shearing blade head 52 is fixedly connected to the mounting groove 51 through a plurality of fixing bolts 53 .

[0030] A scale 73 is provided on the upper side of the lateral strip 7 .

[0031] A through hole 81 is reserved at the upper portion of the slider 8 . The through hole 81 corresponds to the position of the through-hole sensor 10 and is used to read the value of the scale 73 .

[0032] Working principle: Before using this utility model, Figure 2 , Figure 5As shown, according to the length of the plate to be cut, the slider 8 on the lateral slat 7 is slid, and the value of the scale 73 is read through the through hole 81, so that the slider 8 drives the beam sensor 10 to slide to the specified value. It should be noted that the value zero point of the scale 73 is the shearing position when the flat plate 11 intersects the shearing plate 5, which is convenient for the operator to intuitively read the length of the plate to be cut on the scale 73, and slide the slider 8 on the other side of the lateral slat 7 to the same value in the same way;

[0033] During the shearing operation, the plate to be sheared is transported to the plate 11 on the frame 1 by means of a transport mechanism. Figure 4 , Figure 5 As shown, the leftmost end of the plate passes through the pressing mechanism 3 and the shearing plate 5 in sequence until the end reaches the position of the through-beam sensor 10. The through-beam sensor 10 uses light to pass through the light transmitter from one side to illuminate the photosensitive element of the receiver to sense whether there is an object passing through. When the end of the plate to be sheared passes through, the infrared light is blocked, and the through-beam sensor 10 transmits the signal to the control panel 101. After further collection and processing, the control panel 101 issues an opening command to the hydraulic telescopic rod 1 2 and the hydraulic telescopic rod 2 43 on the hydraulic shearing mechanism 4 in sequence. The hydraulic telescopic rod 1 2 drives the roller 33 at the bottom of the lower pressing plate 21 to contact the upper surface of the plate to be sheared, wherein the spring 34 has an elastic buffering function. The detachable design of the shearing blade 52 on the shearing plate 5 facilitates the inspection and replacement of the shearing blade 52 under long-term use. After the cutting of the plate is completed, the hydraulic telescopic rod 1 2 and the hydraulic telescopic rod 2 43 are both shortened in the opposite direction to drive the pressing mechanism 3 and the shearing plate 5 to return to their original positions, so as to prepare for the next cutting.
