DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, obvious and easy to understand, the specific embodiments of the utility model will be explained in detail below with reference to the drawings.

[0022] As shown in Figure 1 The embodiment of the application provides a die thickness detection large-stroke die clamp, which comprises a seat body 1, a pressing plate 2 and a displacement detection device 3, the seat body 1 comprises a containing end 11 and a protruding connecting end 12, a cavity 13 and an oil hole 14 are arranged in the containing end 11, the oil hole 14 is communicated with the cavity 13, a piston assembly 15 is arranged in the cavity 13, when hydraulic oil enters the cavity 13 through the oil hole 14, the piston assembly 15 can be driven to move up and down, the pressing plate 2 is hinged to the connecting end 12, one end of the pressing plate 2 is in contact with the top of the piston assembly 15, and the other end of the pressing plate 2 is located outside the connecting end 12 and used for clamping a die.

[0023] The displacement detection device 3 comprises a fixed plate 31 and a photoelectric sensor 32, the fixed plate 31 is installed at the side end of the containing end 11, the photoelectric sensor 32 is installed at the top end of the fixed plate 31 and located at the side end of the pressing plate 2 close to the oil cylinder, and the photoelectric sensor 32 is used for detecting the moving distance of the pressing plate 2.

[0024] Specifically, the protruding connecting end 12 of the seat body 1 is provided with a recess for accommodating the pressing plate 2, the pressing plate 2 is located in the recess and hinged to both ends of the connecting end 12 through connecting shafts. The arc-shaped pressing head 21 of the pressing plate 2 is in contact with the top of the piston rod 152, and the arc-shaped clamping head 22 of the pressing plate 2 clamps the die. The sleeve 151 is fixed in the cavity 13, and the piston rod 152 moves up and down along the sleeve 151.

[0025] When the hydraulic oil is injected into the cavity 13 through the oil hole 14, the piston rod 152 is pushed by the hydraulic oil, the piston rod 152 moves outward, thereby pushing the arc-shaped pressing head 21 of the pressing plate 2 to move, the pressing plate 2 rotates around the connecting end 12, and the arc-shaped clamping head 22 of the pressing plate 2 clamps the die. If the photoelectric sensor 32 does not detect the moving data or exceeds the detection range during the rotating and clamping process of the pressing plate 2, the photoelectric sensor 32 sends an alarm signal, so that the operator can be reminded to check in time, and the situation that the die which does not meet the clamping requirements is clamped, thereby causing the equipment to be unable to normally operate, is avoided.

[0026] In the above structure, the photoelectric sensor 32 is arranged to detect the moving distance of the pressing plate 2, so that the die thickness of the die is detected, an alarm signal is sent in time if the die does not meet the clamping requirements, and the staff is reminded to handle. The die thickness detection large-stroke die clamp can not only effectively prevent the situation that the die clamp clamps the die which does not meet the requirements, but also ensure the normal operation of the equipment.

[0027] As shown in Figure 2As shown in the drawings, in one embodiment, the connecting end 12 of the die thickness detection large-stroke die clamp is provided with an elastic assembly 4 away from the accommodating end 11, one end of the elastic assembly 4 is fixed on the connecting end 12, and the other end of the elastic assembly 4 is in contact with the pressing plate 2.

[0028] Specifically, when the hydraulic oil flows into the cavity 13 through the oil hole 14, the hydraulic oil pushes the piston rod 152 to move outward, the piston rod 152 drives the arc-shaped pressing head 21 of the pressing plate 2 to move, the pressing plate 2 rotates around the connecting end 12, and the arc-shaped clamping head 22 of the pressing plate 2 is pressed to clamp the mold. During the pressing process of the pressing plate 2, the elastic assembly 4 is compressed. When the hydraulic oil flows out of the cavity 13 through the oil hole 14, the piston rod 152 moves towards the inside of the cavity 13, at this time, the arc-shaped pressing head 21 of the pressing plate 2 is not forced, and the arc-shaped clamping head 22 of the pressing plate 2 is loosened under the action of the elastic assembly 4. The setting effectively prevents the pressing plate 2 from being unable to loosen the mold.
