DETAILED DESCRIPTION

[0022] The utility model will be further explained in detail below in combination with the drawings and embodiments, but the utility model is not limited to the following embodiments.

[0023] In Figures 1 to 4 the embodiment, a circular tunnel arc-shaped copper water stop pressing machine includes a steel main frame 1, a hydraulic cylinder 3, a dynamic pressure pressing plate 5, and a static pressure pressing plate 6. The steel main frame 1 is made of channel steel and includes a base 1-1, a left side support 1-2, a right side support 1-3, and a top frame 1-4. The base 1-1 is a rectangular steel frame with a middle horizontal reinforcing beam welded in the middle. The middle horizontal reinforcing beam is connected with the static pressure pressing plate 6 through evenly distributed support rods 1-5. The left side support 1-2 and the right side support 1-3 are welded to the left and right sides of the base 1-1, respectively. The left side support 1-2 and the right side support 1-3 have equal widths that are smaller than the width of the base 1-1, improving stability. The top frame 1-4 is welded to the top of the left side support 1-2 and the right side support 1-3. Reinforcing plates 1-6 are welded to the junctions of the left side support 1-2, the right side support 1-3, and the top frame 1-4. Guardrails 4 are installed on the front and rear sides of the top frame 1-4 to ensure the safety of operators.

[0024] U-shaped guide groove 2 is welded on the left and right sides of the lower surface of the top frame 1-4 of the steel main frame 1, and 2-5 hydraulic cylinders 3 are vertically installed in the middle, and in this embodiment, there are 3 hydraulic cylinders 3. The power end of the hydraulic cylinder 3 is connected with a dynamic pressure pressing plate 5. The dynamic pressure pressing plate 5 is an arc-shaped template 5-3, and a cross beam 5-1 is welded between the two ends of the arc-shaped template 5-3. The cross beam 5-1 and the arc-shaped template 5-3 are welded with evenly distributed stiffeners 5-2, which ensure the rigidity and stability of the dynamic pressure pressing plate 5 during pressing. The cross beam 5-1 passes through the U-shaped guide groove 2, which ensures the guidance and stability of the dynamic pressure pressing plate 5 during the up and down movement. The back of the arc-shaped template 5-3 is welded with front and rear baffles along the width direction, and a convex rib is processed in the middle. A concave groove matching the convex rib is processed in the middle of the upper surface of the arc-shaped static pressure pressing plate 6. The width of the arc-shaped static pressure pressing plate 6 is equal to the distance between the front and rear baffles.

[0025] The main operation platform 8 is installed on the left and right sides of the main frame, and the height of the main frame is greater than the height of the operation platform, which is greater than 1 / 2 of the height of the main frame. The main operation platform 8 is connected with the ground and the top of the main frame through the step ladder 7, which is convenient for the operator to go up and down and operate the equipment.

[0026] When in use, the copper sheet raw material is placed on the static pressure pressing plate 6, and the hydraulic cylinder 3 is started. The power end of the hydraulic cylinder 3 pushes the dynamic pressure pressing plate 5 to move downward. The dynamic pressure pressing plate 5 gradually moves downward under the push of the hydraulic cylinder 3, and cooperates with the arc-shaped static pressure pressing plate 6 to press the copper water stop sheet placed on the static pressure pressing plate 6. The convex rib of the dynamic pressure pressing plate 5 matches the concave groove of the static pressure pressing plate 6, which ensures the accurate shape of the copper water stop sheet during pressing. When the dynamic pressure pressing plate 5 is in complete contact with the static pressure pressing plate 6 and reaches the predetermined pressing pressure, the hydraulic cylinder 3 stops working, and the pressing process is completed, such as Figure 5 The hydraulic cylinder 3 returns, the dynamic pressure pressing plate 5 moves upward, and the static pressure pressing plate 6 is separated. The operator stands on the main operation platform 8 through the step ladder 7, approaches the working surface, and takes out the pressed copper water stop sheet from the static pressure pressing plate 6.
