Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically an aluminum rod cutting device. Background Technology

[0002] The aluminum rod cutting device is a highly efficient and precise specialized equipment, mainly used for cutting aluminum rods to a fixed length. It achieves rapid cutting through automated operation, significantly improving production efficiency while ensuring a flat cut surface and accurate dimensions. This device is suitable for aluminum rods of various specifications and can meet the needs of fields such as construction, automobile manufacturing, and aerospace. Its features include simple operation, high stability, and significant reduction in manual intervention and material waste, making it an indispensable tool in modern industrial production.

[0003] While aluminum rod cutting devices can improve production accuracy and flexibility, they still have certain problems: 1) During aluminum rod cutting operations, when waiting for loading after cutting the current workpiece, the cutting machine remains in a high-speed idling state, resulting in a large amount of unnecessary energy consumption. According to actual measurement data analysis, the energy consumption during the actual cutting stage accounts for only 32%-38% of the total energy consumption, while the ineffective energy consumption during idling is as high as 60%, resulting in an overall energy utilization rate of less than 40%, indicating significant energy waste; 2) During aluminum rod cutting, due to the inherent geometric characteristics of cylindrical workpieces, the contact area between traditional planar clamps and the outer circumference of the aluminum rod accounts for only 15%-20% of the surface area, resulting in a significant reduction in effective clamping force. This point-to-line contact clamping method not only fails to meet the stability requirements of high-precision cutting, but also easily causes workpiece displacement and vibration under the action of cutting force, directly affecting processing quality and equipment safety. Therefore, in view of the above situation, it is urgent to develop an aluminum rod cutting device to overcome the shortcomings in current practical applications and meet current needs.

[0029] Preferably, the conveying mechanism 200 includes a lifting frame 210, a conveying roller 220, a drive assembly 230, a bracket 240, and a cylinder a250.

Specifically, the lifting frame 210 is used to load the conveying roller 220, which can adapt to the height of the aluminum rod 500.

[0030] Preferably, the lifting frame 210 further includes a sliding sleeve 211, a sliding shaft 212, a double synchronous pulley set 213, and a synchronous belt a214. The two sliding sleeves 211 are fixed on both sides of the lifting frame 210, the sliding shaft 212 is fixed on the lower surface of the platform 110, the sliding sleeves 211 and the sliding shaft 212 are slidably connected, the double synchronous pulley set 213 passes through one side of the lifting frame 210, and a driven wheel 221 is installed at one end of the conveying roller 220. The driven wheel 221 and the double synchronous pulley set 213 are connected by transmission through the synchronous belt a214. Specifically, the double synchronous pulley set 213, in conjunction with the synchronous belt a214 and the driven wheel 221, drives the conveying roller 220 to rotate. The conveying roller 220 is made of flexible rubber material.

[0031] Preferably, the drive assembly 230 includes a motor 231, a drive pulley 232, a synchronous belt b233, and a tension pulley 234. The motor 231 is fixed to the bottom of the worktable 100, the drive pulley 232 is sleeved on the output shaft of the motor 231, and the tension pulley 234 is installed on the bottom of the table surface 110. The double synchronous pulley set 213, the tension pulley 234, and the drive pulley 232 are connected by the synchronous belt b233. Specifically, the drive assembly 230 can drive the conveyor roller 220 to rotate, thereby moving the aluminum rod 500.

[0032] Preferably, the cutting blade of the reciprocating cutting machine 400 penetrates and extends to the upper surface of the table 110. Specifically, the reciprocating cutting machine 400 can drive the cutting blade to reciprocate horizontally along the cutting groove direction.

[0033] Preferably, there are four positioning mechanisms 300, which are arranged in pairs and side by side. Each positioning mechanism 300 corresponds to a single aluminum rod 500 and is aligned with the aluminum rod 500 along the axial direction. Specifically, the positioning mechanisms 300 are used to clamp and fix the aluminum rod 500.

[0034] Working principle: A set of conveying mechanisms 200 transports aluminum rods 500 towards the reciprocating cutting machine 400. After being transported to the designated position, the high-speed rotating reciprocating cutting machine 400 cuts the rod. During the cutting process, another set of conveying mechanisms 200 transports another aluminum rod 500 in the same direction. When one aluminum rod 500 is cut, the other aluminum rod 500 is also transported to the designated position. Immediately afterwards, the reciprocating cutting machine 400 moves horizontally and performs the cutting operation on the other aluminum rod 500. The interval between the two is small, so the idling time of the reciprocating cutting machine 400 is short, effectively improving work efficiency and reducing energy consumption. It should be noted that when the conveying mechanism 200 transports the aluminum rod 500, the cylinder a250 drives the lifting frame 210 to rise to a certain height, and the conveying roller 220 contacts and supports the aluminum rod 500. Subsequently... The drive assembly 230 drives the double synchronous pulley set 213, which, together with the synchronous belt a214, drives the driven pulley 221, thereby driving the conveyor roller 220 to rotate and convey the aluminum rod 500 in the cutting direction. After the aluminum rod 500 is conveyed to the position, it is fixed by the positioning mechanism 300. When the aluminum rod 500 passes between the two sets of clamping chains 330 and is located on the Y-shaped support 320, the cylinder b350 drives the clamping chains 330 to rise a certain distance, so that the clamping chain 330 part is in close contact with the outer wall of the aluminum rod 500. Then, the cylinder c360 drives the locking frame 340 to descend, thereby forcing the parts of the two sets of clamping chains 330 above the aluminum rod 500 to move closer to each other and close to the outer wall of the aluminum rod 500, and applying downward pressure to the aluminum rod 500, thereby achieving a stable clamping effect on the aluminum rod 500.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
