Description

Technical Field

[0001] The utility model relates to the technical field of profile processing, in particular to a profile cutting machine capable of reducing tailings. Background Art

[0002] Profile cutting machines are commonly used equipment in profile processing, which can cut profiles into specified lengths. Some existing profile cutting equipment includes a fixed chuck, a movable chuck and a cutting device, which are arranged in sequence. The movable chuck and the fixed chuck clamp the profile, and the cutting device cuts off the profile of the corresponding length extending out of the fixed chuck on the side of the fixed chuck away from the movable chuck.

[0003] Both the movable chuck and the fixed chuck are put on the profile and occupy a certain length of the profile. When the profile is cut to the tail material, the movable chuck will be as close to the fixed chuck as possible to increase the length of the tail material extending out of the fixed chuck to achieve the cutting length. However, for some cutting lengths, the length of the profile extending out of the fixed chuck is still not enough to achieve the required cutting length, which will cause the tail material to be too long and cause more material waste.

The chip guard plate 16 can block the chips generated during cutting on the right side of the fixed chuck 4 from flying onto the cutting movable assembly 6, thereby improving the movement accuracy of the cutting movable assembly 6 without affecting the movement of the cutting movable chuck 2.

[0066] In some specific embodiments, referring to Figure 5 The profile cutting machine also includes a feed clamping device, which is arranged on the left side of the fixed chuck 4, and the movable chuck 2 is arranged on the left side of the feed clamping device; the feed clamping device includes a feed clamping drive unit 71 and two feed clamping arms 72, the feed clamping drive unit 71 is connected to the frame 1, and the two feed clamping arms 72 are respectively arranged on both sides of the radial direction of the clamping hole of the fixed chuck 4, and the two feed clamping arms 72 are transmission-connected to the feed clamping drive unit 71, and the feed clamping drive unit 71 can drive the two feed clamping arms 72 to approach each other to clamp the profile 8 or move away from each other to loosen the profile 8.

[0067] When the profile 8 is pushed to the right, the mobile chuck 2 will clamp the profile 8 and move to the right, and the two feed clamping arms 72 will not clamp the profile 8. At this time, if the set length of the profile 8 is greater than the moving distance of the mobile chuck 2, the two feed clamping arms 72 will clamp the profile 8 to prevent the profile 8 from moving. The mobile chuck 2 will release the profile 8 and move to the left to the required distance first, and then the two feed clamping arms 72 will release the profile 8, and the mobile chuck 2 will clamp the profile 8 and move to the right. The feed clamping drive unit 71 can adopt a gear rack structure or a cylinder, and the two feed clamping arms 72 can be arranged front and back.
