A sheet metal plate is fastened and installed by screws in the support above the tool cabinet and the control cabinet, and serves as a workbench 4. The frame 1 is provided with a control screen which is electrically connected with the controller.

[0030] The workbench 4 is embedded with the lower heating plate 5. The upper end of the frame 1 is provided with a lifting assembly 6, and the lifting assembly 6 is any one of a pneumatic cylinder, a hydraulic rod and an electric telescopic rod 12. The extending end of the lifting assembly 6 penetrates through the top end of the frame 1 and is connected with the template support 7, and the template support 7 is vertically slidably installed in the frame 1. The lower end of the template support 7 is fastened and installed with a mounting plate 8, and the lower end of the mounting plate 8 is embedded with the upper heating plate 10, and the upper heating plate 10 is opposite to the lower heating plate 5.

[0031] In the present embodiment, the upper heating plate 10 and the lower heating plate 5 are both electric heating plates, and the heating temperature is adjustable.

[0032] According to the above technical solution:

[0033] In use, the workpiece to be processed is placed on the lower heating plate 5, and the lifting assembly 6 is started. The lifting assembly 6 drives the template support 7 to descend, and the template support 7 drives the upper heating plate 10 to descend and press on the surface of the workpiece. Through synchronous heating treatment of the upper heating plate 10 and the lower heating plate 5, the workpiece is subjected to the same temperature from top to bottom, so that the workpiece is heated more uniformly, and problems such as cracking caused by uneven heating are avoided.

[0034] For different workpieces, the upper heating plate 10 does not need to descend and press on the surface of the workpiece. The specific use method depends on the implementation condition.

[0035] In a further embodiment of the present application, in order to avoid the sudden descent of the template support 7 caused by power failure or circuit damage of the lifting assembly 6, which affects the stability and safety of operation. In this embodiment, the upper end face of the template support 7 is tightly installed with an anti-falling rod 11, a plurality of clamping grooves 14 are axially spaced on the side wall of the anti-falling rod 11, and an electric telescopic rod 12 is tightly installed on the top wall of the frame 1, and the extending end of the electric telescopic rod 12 is provided with a clamping piece 13 matched with the clamping groove 14.

[0038] According to the above technical solution:

[0039] After the lifting assembly 6 drives the template support 7 to ascend to the required position, the electric telescopic rod 12 is extended to drive the clamping piece 13 to move, so as to be clamped in the clamping groove 14, thereby braking the anti-falling rod 11. When the template support 7 needs to be lifted again, the electric telescopic rod 12 is retracted, and the clamping piece 13 is separated from the clamping groove 14. When the template support 7 is at rest, the clamping piece 13 and the clamping groove 14 are matched to brake the template, thereby preventing the template support 7 from suddenly descending when the lifting assembly 6 fails and causing safety hazards.

[0040] In a further embodiment of the present application, in order to facilitate the movement of the equipment, the common way is to set a driving wheel 23 such as a universal wheel at the bottom end of the frame 1.

[0042] The principle details of the embodiment are as follows:

[0043] The rotating seat 17 is tightly and fixedly installed around the bottom end of the frame 1. The sleeve 18 is rotatably installed at the lower end of the rotating seat 17, the sleeve 18 is hollow, and the periphery is provided with a notch into which a finger can be inserted. The side wall of the sleeve 18 is provided with a truss, and the driving wheel 23 is rotatably installed on the truss. The lower end of the sleeve 18 is open, the rotating shaft 19 is rotatably installed on the inner top wall of the sleeve 18, the rotating shaft 19 extends to the knob 20 which is fixedly sleeved and provided with teeth, and the knob 20 is located at the notch of the sleeve 18. The rotating shaft 19 below the knob 20 is a threaded segment, and the driving block 21 is threadedly screwed on the threaded segment. The driving block 21 is sleeved with the cushion block 22, the upper end of the cushion block 22 is open, and the driving block 21 is clamped in the opening of the cushion block 22. The inner wall of the cushion block 22 and the inner wall of the sleeve 18 are both provided with a block, and the outer wall of the cushion block 22 and the outer wall of the driving block 21 are both provided with a vertical key groove matched with the block, so that the driving block 21 and the cushion block 22 are vertically slidably matched, and the cushion block 22 and the sleeve 18 are vertically slidably matched.

The safety grating 2 is an optoelectronic protection device, including a transmitting end and a receiving end. The safety grating 2 is connected to a safety relay, and if an object is detected, the power source that may cause harm will be automatically removed. The safety grating 2 cooperates with an alarm, such as a voice broadcast or a buzzer, to issue a warning when the receiving end is blocked by a human body or other objects and cannot receive signals. The safety relay can also temporarily suspend the function of the safety grating 2 to allow the object to pass through the safety grating 2 without generating a protection signal, which is suitable for some semi-automatic procedures. This increases the safety of the equipment.
