Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to a roll changing device for a sheet metal roll press. Background Technology

[0002] Knurled metal sheets are a common type of sheet material. During processing, a bare sheet is typically placed in a roller press for knurling to form the finished product. However, due to the inconsistent specifications of the knurling on the sheet surface, the rotating rollers used for knurling need frequent replacement. Current replacement methods involve direct disassembly at the knurling machine location. This results in limited space for roller changes, inconvenient operation, long replacement times, and low efficiency. Furthermore, for ease of replacement, the knurling rollers are often positioned above the sheet material. During replacement, this may require the assistance of overhead cranes, which bear the weight of the entire knurling roller. There is a risk of the roller falling off during replacement, thus posing a certain degree of danger. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a roller changing device for a sheet metal roller press.

[0004] This utility model is achieved using the following technical solution: a roller changing device for a sheet metal roller press, comprising a mounting component and a pushing component on one side of the roller press. The mounting component is used to mount the lower pressure roller. A track is provided on one side of the roller press, extending outward. The mounting component is mounted on the track and slides along the track toward or away from the roller press. The pushing component is connected to the mounting component and pushes the mounting component away from or into the roller press.

[0005] The rolling mill includes a conveying section and a rolling section. An installation area is provided between the conveying section and the rolling section for the installation component to be inserted. The track extends into the installation area. The pushing component pushes the installation component into the installation area and places it below the rolling section. A gap is formed between the installation component and the rolling section for the plate to pass through.

[0006] The rolling section includes a mounting base, on which an upper pressure roller is rotatably connected. When the mounting assembly is moved to the mounting area, the upper pressure roller is opposite to the lower pressure roller, and the sheet material passes through the gap between the upper pressure roller and the lower pressure roller.

[0007] The mounting assembly includes a mounting frame with track wheels at the bottom. The mounting frame has a groove for placing the lower pressure roller, and the groove has a latch for closing the groove. The end of the lower pressure roller is placed in the groove and locked in the groove by the latch.

[0008] The latch includes a locking plate, one end of which is hinged to the edge of the groove, and the other end of which is provided with an outwardly extending ear plate. A first fixing hole is provided on the ear plate, and a second fixing hole is provided on the mounting bracket at the position corresponding to the first fixing hole.

[0009] The lower pressure roller includes a pressure roller body and a bearing. The end of the pressure roller body is provided with a rotating shaft. The rotating shaft is coaxial with the pressure roller body. The bearing is sleeved on the rotating shaft and is interference-fitted with the rotating shaft. When the lower pressure roller is placed in the groove, the outer ring of the bearing abuts against the inner wall of the groove. The locking buckle is pressed onto the outer ring of the bearing.

[0010] The pushing assembly includes a pushing cylinder, the drive shaft of which is fixed to the mounting assembly for pushing the mounting assembly to move back and forth along the track.

[0011] Compared to existing technologies, this invention offers several advantages, especially when changing rollers. The installation assembly can be moved using a push-moving cylinder and pulled out of the roller press for easy replacement. The larger space available during replacement makes operation more convenient. After removing the locking clips, the roller can be lifted using a crane. Throughout the disassembly process, the weight of the roller is supported by the mounting frame, reducing the possibility of slippage and enhancing safety. The replaced roller is also lifted by a crane. Due to the larger surrounding space, it can be directly hoisted onto the mounting frame, making replacement even more convenient. After replacement, the push-moving cylinder can be activated to move the mounting frame back under the upper pressure roller, further simplifying the roller replacement process.

The mounting assembly 1 is used to mount the lower pressure roller 423. A track 3 is provided on one side of the roller press, extending outward. The mounting assembly 1 is mounted on the track 3 and slides along the track 3 towards or away from the roller press 4. The pushing assembly 2 is connected to the mounting assembly 1 and pushes the mounting assembly 1 away from or into the roller press 4. When a roller change is needed, the pushing assembly 2 can move the mounting assembly 1 to be pulled out of the roller press 4, thus facilitating the replacement. The device offers ample space for replacement and makes operation more convenient.

[0017] In this embodiment, the rolling mill includes a conveying section 41 and a rolling section. An installation area for inserting the mounting assembly 1 is provided between the conveying section 41 and the rolling section. A track 3 extends into the installation area. A pushing assembly 2 pushes the mounting assembly 1 into the installation area and places it below the rolling section. A gap is formed between the mounting assembly 1 and the rolling section for the sheet material 5 to pass through. The rolling section 42 consists of at least an upper pressure roller 422 and a lower pressure roller 423. The rolling section includes a mounting base 421, on which the upper pressure roller 422 is rotatably connected. When the mounting assembly 1 is pushed into the installation area, the upper pressure roller 422 faces the lower pressure roller 423, and the sheet material 5 passes through the gap between the upper pressure roller 422 and the lower pressure roller 423.
