2. inside coolant entered into the medium pipe through the intake pipe to come out from the outlet duct, accomplish the cooling work to the inside product of lower mould, medium pipe annular parcel can carry out even cooling work to the shaping product in the outside of mobile cover.
3. When a workpiece is placed on the lower die, the lower die is driven to move to the position right below the upper die through the electric telescopic rod, so that die assembly is realized; when a workpiece is placed before die assembly and after die assembly processing is finished, the lower die is driven by the electric telescopic rod to be away from the upper die, so that the phenomenon that the upper die accidentally drops to cause a safety accident when the workpiece is taken and placed is avoided, and the safety of the invention is improved; and in the left-right sliding process, the double guidance is realized through the guiding action of the first sliding groove and the first sliding block and the guiding action of the electric telescopic rod closing the L-shaped sliding rail and the first vertical through hole, so that the left-right sliding is reliable.
4. In an initial state, the second hollow cylinder is separated from the first hollow semi-cylinder, the second conical surface of the third fixed block is supported on the first conical surface of the second fixed block, so that the second hollow cylinder is conveniently and reliably supported, and the second spring is in a compressed state;
in the process of closing the dies by moving the upper die downwards, the connecting wire drives the counterweight balls to move downwards, when the counterweight balls contact the upper ends of the vertical guide rods, the upper die continues to move downwards, the vertical guide rods move downwards under the action of gravity of the counterweight balls, the second sliding block slides downwards on the vertical sliding rods due to the fixed length of the two first connecting rods, the two vertical sliding rods approach to each other, the second conical surface is far away from the first conical surface, so that the third fixing block loses support, the second hollow cylinder moves downwards under the action of the elasticity of the second spring and the gravity of the third fixing block, so that the two second hollow cylinders on the two vertical sliding rods approach to each other and approach to the first hollow semi-cylinder downwards, the first hollow semi-cylinder and the second hollow cylinder contact to form a closed structure, one end of each of the first hollow semi-cylinder and one end of each second hollow cylinder are an open end, and the other end, when the upper die and the lower die are closed, the opening end is in contact with or close to the front side wall or the rear side wall of the upper die, so that the contact position of the lower die and the upper die is realized, and the residues of the workpiece at the closed position are prevented from splashing and damaging a human body through the protection of the closed structure; or when the lower die is a high-temperature die, high-temperature scalding caused by misoperation in the die assembly machining process is avoided.

the alarm is arranged on the base (13) device;
the controller is arranged on the base (13) device and is electrically connected with the distance sensor, the speed sensor, the lamp panel material identification device, the first detection device and the alarm, material parameters corresponding to the type of the lamp panel material are preset in the controller, and the material parameters comprise the yield strength of the material, the strain coefficient of the material and a comprehensive stress reference value;
the controller is based on distance sensor, speed sensor, lamp plate material recognition device, first detection device control alarm work, includes following step:
step 1: before the lamp panel is processed, the controller controls the lamp panel material identification device to work, and material parameters corresponding to the current lamp panel material type are obtained based on the detection result of the lamp panel material identification device;
step 2: the controller calculates a comprehensive stress evaluation value of the lamp panel based on the step 1, the first detection device and the formula (1);
Figure FDA0002561984860000051
wherein F is the comprehensive stress evaluation value of the lamp panel, A is the area of the surface to be processed of the lamp panel obtained by the controller based on the first detection device, and sigma is1The yield strength is corresponding to the type of the current lamp panel material, and B is the strain coefficient corresponding to the type of the current lamp panel material; delta H is the maximum vertical deformation amount in each variable profile of the surface to be processed before and after the lamp panel is processed; s is the thickness of the surface of the lamp panel to be processed, and lambda is a preset fillet influence coefficient; r is the average radius of a fillet in the upper die used for processing the processing surface of the lamp panel; n is an upper mold andthe fit coefficient related to the die clearance and the lubricating condition of the lower die, wherein the value of n is 0.8-1.2; m is the current processing frequency of the lamp panel, and when the current processing procedure is a first procedure, M is 1; c is the die precision of the lamp panel processing die;
and step 3: the controller calculates the unqualified lamp panel processing score based on the step 2, the distance sensor, the speed sensor and the formula (2);
Figure FDA0002561984860000061
q is the unqualified grading of the lamp panel, and F0Is a comprehensive stress reference value corresponding to the current lamp panel material type, ln is a logarithm taking a constant e as a base number, exp is an exponential function taking a natural constant e as a base, K1Is a first predetermined coefficient, K2Is a second predetermined coefficient, K3Is a third predetermined coefficient, D1Initial height of upper die from lower die, D, for first distance sensor detection0Is a reference value of the initial height of the upper die from the lower die, V is a detection value of a speed sensor, V0The reference value of the descending speed of the upper die is obtained;
and 4, step 4: and (3) comparing the unqualified lamp panel processing score calculated in the step 3 with a preset unqualified lamp panel processing score reference value by using the controller, and when the unqualified lamp panel processing score calculated in the step 3 is larger than the preset unqualified lamp panel processing score reference value, controlling an alarm to give an alarm by using the controller.
