The bottom of the sliding rod 51 is fixedly connected to an extrusion block 52, and the top of the extrusion block 52 is movably connected to a hydraulic press 4.

[0023] As a technical optimization solution of the utility model, by setting up the extrusion mechanism 5, it can cooperate with the hydraulic press 4, and drive the extrusion block 52 downward to move and extrude through the output end of the hydraulic press 4. The extrusion block 52 moves downward through the sliding rod 51, thereby improving the stability of the extrusion block 52 when extruding downward, and improving the use effect of the extrusion block 52.

[0024] refer to Figure 3 The adjustment and replacement mechanism 6 includes an adjustment plate 601, which is movably connected to the top of the bottom plate 1. The top of the adjustment plate 601 is movably connected to an arc plate 602. The front and rear sides of the bottom of the arc plate 602 are fixed with locking blocks 603. The front and rear sides of the top of the adjustment plate 601 are provided with grooves 604. The outer side of the adjustment plate 601 is fixedly connected to an L-shaped plate 605. The number of the L-shaped plates 605 is four.

[0033] As a technical optimization solution of the present invention, by providing a reinforcement frame 10 , the hydraulic press 4 can be reinforced and fixed on the top of the top plate 3 , thereby improving the fixing effect of the hydraulic press 4 .

[0034] The working principle and use process of the utility model are as follows: when in use, the hydraulic press 4 is started, and the output end of the hydraulic press 4 drives the extrusion block 52 to extrude downward, and the extrusion block 52 drives the sliding rod 51 to move downward, and the extrusion block 52 extrude and bends the evaporator through the arc plate 602 and the adjustment plate 601. After long-term use, the arc plate 602 frictionally wears and reduces the accuracy. When replacing the arc plate 602, by pressing the prying plate 611, the prying plate 611 is pressed and tilted on the surface of the L-shaped plate 605 through the pin shaft. The prying plate 611 drives the insertion rod 608 to tilt outward, thereby driving the insertion rod 608 to withdraw from the inside of the locking block 603. The reverse operation can be performed during installation, which increases the convenience of replacement for operators and reduces the use cost of the equipment.

[0035] To sum up: the bending device for evaporator production, through the coordinated use of the bottom plate 1, the support frame 2, the top plate 3, the hydraulic press 4, the extrusion mechanism 5 and the adjustment and replacement mechanism 6, solves the problem that when the evaporator is bent, the upper mold continues to bend the evaporator by squeezing the lower mold. After long-term use, the arc-shaped part where the upper mold and the lower mold contact will be worn due to long-term extrusion, which will cause errors in the subsequent bending of the evaporator, making the evaporator substandard. Manual replacement of the entire lower mold is required, which reduces the bending efficiency of the evaporator and increases the cost of equipment use.
