A ribbing device

Abstract

This utility model discloses a rib-pressing device, including a workbench with an operating opening. A left support block, a left pressure block, a right pressure block, and a right support block are sequentially arranged within the operating opening. Rib grooves are formed on the inner sides of the left and right support blocks, and raised strips are formed on the outer sides of the left and right pressure blocks. Mounting blocks a and b are mounted on the lower surface of the workbench. A receiving cavity a is located between mounting block a and the left support block, and a receiving cavity b is located between mounting block b and the right support block. An inward pushing mechanism is installed within receiving cavities a and b. A receiving cavity c is located between the left and right pressure blocks, and an outward expanding mechanism is installed within receiving cavity c. The outer shell is positioned between the left support block, left pressure block, right pressure block, and right support block, respectively. Simultaneous activation of the inward pushing mechanism and the outward expanding mechanism closes the left support block, left pressure block, right pressure block, and right support block, thereby forming reinforcing ribs on both sides of the outer shell with the cooperation of the rib grooves and raised strips. This increases the strength of the outer shell and makes it less prone to deformation during production and transportation.

Mounting block a and mounting block b are installed on the lower surface of the workbench, and there is a receiving cavity a between mounting block a and the left support block, and a receiving cavity b between mounting block b and the right support block. An inward pushing mechanism is arranged in the receiving cavities a and b, and a receiving cavity c is arranged between the left pressing block and the right pressing block.

[0021] In this embodiment, as Figure 1 As shown, a rib-pressing device includes a workbench 1 with an operating opening. A fixing block 3 is provided on the outer side of the operating opening, and a left support block 6, a left pressing block 5, a right pressing block 4, and a right support block 11 are arranged sequentially inside the operating opening. Rib grooves 7 are provided on the inner sides of the left support block 6 and the right support block 11, and protrusions 10 corresponding to the rib grooves 7 are provided on the outer sides of the left pressing block 5 and the right pressing block 4. An mounting block a15 and a mounting block b19 are installed on the lower surface of the workbench 1. A receiving cavity a8 is provided between the mounting block a15 and the left support block 6, and a receiving cavity b2 is provided between the mounting block b19 and the right support block 11. An inward pushing mechanism 21 is provided in the receiving cavities a8 and b2. A receiving cavity c9 is provided between the left pressing block 5 and the right pressing block 4, and an outward expanding mechanism 23 is provided in the receiving cavity c9. By placing both ends of the outer shell of the oxygen copper heat exchanger on the fixed block 3, the two sides of the outer shell are respectively located between the left support block 6, the left pressure block 5 and the right pressure block 4 and the right support block 11. Then, the inner push mechanism 21 and the outer expansion mechanism 23 are activated simultaneously to close the left support block 6, the left pressure block 5 and the right pressure block 4 and the right support block 11. Thus, with the cooperation of the rib groove 7 and the convex strip 10, reinforcing ribs (grooves) are formed on both sides of the outer shell, thereby increasing the strength of the outer shell and making it less prone to deformation during production and transportation.

[0022] Furthermore, such as Figure 3 As shown, a return spring a14 is provided on the outer surface of mounting block a15 and left support block 6, a return spring b17 is provided on the outer surface of left pressure block 5 and right pressure block 4, and a return spring c18 is provided on the outer surface of right support block 11 and mounting block b19. Furthermore, two mounting rods 16 are provided between mounting block a15 and mounting block b19. Corresponding through holes are provided on left support block 6, left pressure block 5, right pressure block 4, and right support block 11. The mounting rods 16 pass through these through holes, and the diameter of the through holes is larger than the diameter of the mounting rods 16. In this embodiment, as... Figure 2 As shown, the inner push mechanism 21 includes an inner push block 20, the lower end of which is mounted on the piston rod a of the cylinder a22. The inner push block 20 is located between the two mounting rods 16, and the upper end length of the inner push block 20 is less than the lower end length. The outer expansion mechanism 23 includes an outer expansion block 13, the lower end of which is mounted on the piston rod b of the cylinder b24. The outer expansion block 13 is located between the two mounting rods 16, and the upper end length of the outer expansion block 13 is less than the lower end length. Specifically, after the outer shell is fixed, the staff simultaneously activates the inner push mechanism 21 and the outer expansion mechanism 23. First, let's describe the operation of the inner push mechanism 21: the piston rod a on cylinder a22 extends, causing the inner push block 20 to move upwards. Since the upper length of the inner push block 20 is less than the lower length, during its upward movement, the inner push block 20 compresses the left support block 6 to move towards the left pressure block 5 and the right support block 11 to move towards the right pressure block 4. At this time, the return springs a14 and c18 are stretched. Next, let's describe the operation of the outer expansion mechanism 23: the piston rod b on cylinder b24 extends, causing the outer expansion block 13 to move upwards. Since the upper length of the outer expansion block 13 is less than the lower length, during its upward movement, the outer expansion block 13 compresses the left pressure block 5 to move towards the left support block 6 and the right pressure block 4 to move towards the right support block 11. At this time, the return spring b17 is stretched. Therefore, under the combined action of the outward expansion block 13 and the inward push block 20, the left support block 6, the left pressure block 5, the right pressure block 4, and the right support block 11 are closed, thereby forming reinforcing ribs (grooves) on both sides of the outer shell with the cooperation of the rib groove 7 and the protrusion 10, which increases the strength of the outer shell and makes it less prone to deformation during production and transportation. After the ribs are pressed, the cylinders a22 and b24 synchronously drive the inward push block 20 and the outward expansion block 13 to move downward. Since the return springs a14, c18, and b17 are all in the extended state, under the action of the elastic force, the return springs a14, c18, and b17 will correspondingly drive the left support block 6, the left pressure block 5, the right pressure block 4, and the right support block 11 to reset, thus making it easier for the workers to remove the outer shell from the fixing block 3.

[0023] In this embodiment, a positioning step 12 is provided on the inner side of the fixing block 3. Specifically, the two ends of the outer shell are placed on the positioning step 12. The main function of the positioning step 12 is to provide a positioning reference for the placement of the outer shell, so that the reinforcing ribs formed on both sides of the outer shell are located in the middle of the outer shell.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
