Description

Technical Field

[0001] This utility model relates to the field of end cap processing technology, specifically to an anti-scratch device for a hydraulic press used in end cap processing. Background Technology

[0002] A head press is a device used to press heads (i.e., end caps of various pressure vessels). Heads are an important component of pressure vessels, and their shape and size directly affect the vessel's performance and safety. Therefore, the head manufacturing process requires precise control, and the head press is one of the key pieces of equipment used to accomplish this task.

[0003] When removing end caps from existing hydraulic presses, tools are needed to assist in demolding and transferring the end caps because the end caps are located inside the lower mold base. As a result, the end caps are easily scratched when using tools, resulting in scratches on the surface of the end caps, and the presses do not have the function of preventing scratches on the end caps. Utility Model Content

[0004] The purpose of this utility model is to provide a scratch-resistant device for a hydraulic press used for end cap processing, so as to solve the problem mentioned in the background art that the currently used hydraulic presses for end caps do not have a scratch-resistant function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scratch-resistant device for a hydraulic press for end cap processing, comprising: a base, wherein a lower mold base and a hydraulic press body are respectively installed on the top of the base;

[0006] Both sides of the lower mold base are provided with arc-shaped blocks. A connecting block is installed on one side of the arc-shaped block, and a connecting rod is connected to one side of the connecting block. The bottom of the connecting rod is connected to a movable plate via a slider. A bidirectional lead screw is connected through the middle of the two sets of movable plates. A drive motor is connected through the base on one side of the bidirectional lead screw. A first telescopic rod is connected between the two sets of connecting rods. A second telescopic rod is connected to one side of the connecting rod. A screw rod is connected through one end of the second telescopic rod. The input end of the screw rod is connected to a drive motor via a coupling. A rubber pad is installed on the inner side of the arc-shaped block.

[0007] Preferably, one end of the screw is mounted on the top of the base via a bearing seat, and the screw and the second telescopic rod are connected by a thread.

[0008] Preferably, the connecting block has a rotating block connected inside by a rotating shaft, and one end of the rotating block is connected to a ball bearing by a sliding groove.

[0009] Preferably, a pull rod that passes through the connecting block is connected to one side of the ball, and a movable spring is connected between the pull rod and the groove of the connecting block.

[0010] Preferably, both ends of the connecting rod are provided with slots, and the connecting rod is inserted into one side of the connecting block through the slots.

[0011] Preferably, the ball bearings form a sliding structure with the connecting block via a groove.

[0012] Preferably, two sets of rotating blocks are symmetrically installed about the center line of the connecting blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using the anti-scratch device of the hydraulic press for end cap processing, the end cap can be ejected from the lower mold base by the ejector cylinder in the lower mold base. Then, through the cooperation of the drive motor and the double-acting screw, the movable plate drives the connecting rod and the arc-shaped block to move, thereby clamping the end cap on the lower mold base. At the same time, through the cooperation of the transmission motor and the screw, the second telescopic rod drives the connecting rod and the arc-shaped block to move, thereby moving the end cap out of the lower mold base. The rubber pad on the inner wall of the arc-shaped block can prevent scratching the end cap and facilitate the quick removal of the middle end cap from the hydraulic press. This is the characteristic of the anti-scratch device of the hydraulic press for end cap processing.

[0014] 1. The anti-scratch device of the hydraulic press for processing end caps can be used by starting the drive motor. With the cooperation of the double-acting screw and the movable plate, the connecting rod drives the two sets of arc blocks to move closer to each other, and then the end cap can be clamped. At the same time, the screw and the second telescopic rod are used to transfer the end cap between the two sets of arc blocks from the lower mold base. The rubber pad on the inner wall of the arc block can prevent scratching the end cap.

[0015] 2. The anti-scratch device of the hydraulic press for end cap processing allows the pull rod to be pulled outward of the connecting block according to the usage requirements. The pull rod will drive the rotating block to rotate through the ball bearings, causing the rotating block to move out of the slot of the connecting rod. At this time, the rotating block no longer limits the connecting rod, thus separating the connecting rod from the arc block. This makes it convenient to replace the arc block and rubber gasket according to the size of the end cap and the wear of the rubber gasket. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 This utility model provides a technical solution: a scratch prevention device for a hydraulic press for end cap processing, comprising: a base 1, with a lower mold base 2 and a hydraulic press body 3 respectively installed on the top of the base 1;

[0023] Both sides of the lower mold base 2 are provided with arc-shaped blocks 4. A connecting block 5 is installed on one side of the arc-shaped block 4. A connecting rod 6 is connected to one side of the connecting block 5. The bottom of the connecting rod 6 is connected to a movable plate 7 via a slider. A bidirectional lead screw 8 is connected through the middle of the two sets of movable plates 7. A drive motor 9 is connected through the base 1 on one side of the bidirectional lead screw 8. A first telescopic rod 10 is connected between the two sets of connecting rods 6. A second telescopic rod 11 is connected to one side of the connecting rod 6. A screw 12 is connected through one end of the second telescopic rod 11. The input end of the screw 12 is connected to a drive motor 13 via a coupling. A rubber pad 19 is installed on the inner side of the arc-shaped block 4. One end of the screw 12 is installed on the top of the base 1 via a bearing seat. The screw 12 and the second telescopic rod 11 are connected by a thread. The movable plate 7 and the bidirectional lead screw 8 are connected by a thread.

[0024] In specific implementation, the anti-scratch device of the hydraulic press for processing the end caps is used to eject the end caps from the lower mold base 2 through the ejection cylinder inside the lower mold base 2 when it is necessary to remove the end caps that have been hydraulically pressed. Then, the drive motor 9 is started, and the drive motor 9 will drive the double-acting screw 8 to rotate through the coupling. Movable plates 7 are sleeved at both ends of the double-acting screw 8, and the movable plates 7 are slidably connected in the groove of the base 1. Therefore, when the double-acting screw 8 rotates, it will drive the two sets of movable plates 7 to move in opposite directions. When the two sets of movable plates 7 move closer to each other, they will drive the two sets of connecting rods 6 to move closer to each other through the top slider. The movement of the connecting rods 6 will drive the two sets of arc blocks 4 to move through the connecting block 5, so that the two sets of arc blocks 4 can clamp the end caps on the top of the lower mold base 2. Since the inner wall of the arc block 4 is equipped with a rubber pad 19, which is made of soft material, the rubber pad can avoid scratching the end caps when clamping them.

[0025] Then start the drive motor 13, which will drive the screw 12 to rotate. A second telescopic rod 11 is sleeved on the outside of the screw 12. The second telescopic rod 11 is connected to the connecting rod 6, and the connecting rod 6 is slidably connected to the top of the movable plate 7. Therefore, when the screw 12 rotates, it will drive the connecting rod 6 to move through the second telescopic rod 11. At the same time, the first telescopic rod 10 between the two sets of connecting rods 6 will drive the other set of connecting rods 6 to move synchronously. The movement of the connecting rod 6 will transfer the middle end cap from the lower mold base 2 through the arc block 4, which is convenient for quick removal of the end cap without scratching it.

[0026] See Figure 1 and Figure 2 It can be seen that during use, the moving plate 7 can be driven by the drive motor 9 and the bidirectional lead screw 8. The movement of the moving plate 7 will drive the arc block 4 to move through the connecting rod 6 and the connecting block 5, so that the arc block 4 clamps the end cap through the rubber pad on the inner wall. At the same time, the rubber pad can prevent the end cap from being scratched when it is removed.

[0027] Inside the connecting block 5, a rotating block 14 is connected via a rotating shaft. One end of the rotating block 14 is connected to a ball bearing 15 via a sliding groove. A pull rod 16 that passes through the connecting block 5 is connected to one side of the ball bearing 15. A movable spring 17 is connected between the pull rod 16 and the groove of the connecting block 5. Both ends of the connecting rod 6 are provided with slots 18. The connecting rod 6 is inserted into one side of the connecting block 5 through the groove. The ball bearing 15 forms a sliding structure with the connecting block 5 through the sliding groove. Two sets of rotating blocks 14 are symmetrically installed about the center line of the connecting block 5. The rotating blocks 14 are rotatably connected to the groove of the connecting block 5 via a rotating shaft.

[0028] In practical implementation, the anti-scratch device of the hydraulic press for end cap processing can be used to replace the arc block 4 and the inner wall rubber gasket by simply pulling the pull rods 16 at both ends of the connecting block 5 to the sides. The movement of the pull rods 16 will drive the ball bearings 15 to move. Since the pull rods 16 can only move up and down along the groove of the connecting block 5, the pull rods 16 will drive the ball bearings 15 to slide along the slide groove at one end of the rotating block 14. At the same time, the ball bearings 15 will pull the rotating block 14 to rotate through the slide groove, so that the rotating block 14 moves out of the slots 18 at both ends of the connecting rod 6. The connecting rod 6 is not limited by the rotating blocks 14 at both ends, so the connecting rod 6 can be quickly separated from the connecting block 5. Since the connecting block 5 is installed on one side of the arc block 4, the connecting rod 6 can be quickly separated from the arc block 4, which is convenient for replacing the arc block 4 and the rubber gasket. This allows for the clamping of end caps of different sizes without scratching the end caps.

[0029] Conversely, simply insert the connecting rod 6 into the groove of the connecting block 5. During the insertion process, the connecting rod 6 will compress the rotating block 14, causing the rotating block 14 to rotate. This rotation, along with the sliding groove and the ball bearing 15, will push the pull rod 16 to move. At this time, the movable spring 17 on the outside of the pull rod 16 will be in a compressed state. When the slots 18 at both ends of the connecting rod 6 are aligned with the rotating block 14, the pull rod 16 will be reset by the movable spring 17 and will drive the rotating block 14 to rotate in the opposite direction through the ball bearing 15. Then, the rotating block 14 will be locked in the groove of the connecting rod 6. The connecting rod 6 can be quickly fixed to one side of the connecting block 5 by the rotating block 14.

[0030] See Figure 1 , Figure 3 and Figure 4 It can be seen that during use, the connecting rod 6 can be separated from the connecting block 5 on one side of the arc block 4 according to the wear condition of the rubber pad and the curvature of the arc block 4, so that the arc block 4 can be quickly replaced, which is convenient for clamping different sizes of end caps without scratching the end caps.

[0031] In summary, the anti-scratch device of this hydraulic press for head processing allows for the placement of the head material in the lower die holder 2 according to usage requirements. Then, the hydraulic press body 3 is activated, causing the upper die holder of the hydraulic press body 3 to move downwards. With the cooperation of the upper and lower die holders 2, the material can be hydraulically pressed into the shape of a head. The head is then ejected from the lower die holder 2 by an ejector cylinder inside the lower die holder 2. Furthermore, the arc-shaped block 4 and rubber pad can transfer the head off the lower die holder 2. This is the characteristic of the anti-scratch device of the hydraulic press for head processing. Content not described in detail in this specification is prior art known to those skilled in the art.

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.
