Description

Cutting equipment with double clamping combinations on discharging side

Technical Field

The invention relates to the field of cutting machinery, in particular to cutting equipment with double clamping combinations on a discharging side.

Background

The section bar has been widely used in our lives, for example, in the wardrobe field as a support beam, or in the ceiling field as a decorative section bar, etc., and the section bar applied to a specific field has a specific specification length. Whereas the length of the original profile produced by the processing machine is often as long as several tens of meters, or more. In order to be able to be used in specific applications, the long profile must be cut to length according to the requirements of the application, for which a cutting machine is required. The vertical laser pipe cutting machine comprises a machine body, a left full-stroke rear chuck, a right full-stroke front chuck, a laser cutting head, an automatic feeding frame, a lifting material supporting frame and an unloading part, wherein the left full-stroke rear chuck, the right full-stroke rear chuck and the right full-stroke front chuck are sequentially arranged on the machine body in a sliding mode. The specific process is as follows: the workpiece is placed on an automatic feeding frame, the automatic feeding frame sends the workpiece to the center of a machine tool, the lifting material supporting frame is lifted to support the workpiece to the centers of the left full-stroke rear chuck, the right full-stroke rear chuck and the right full-stroke front chuck, the right full-stroke rear chuck moves to clamp the workpiece and drives the workpiece to be conveyed to the front chuck, the machine tool starts to cut the workpiece, an unloading bracket of an unloading part is lifted to follow when cutting is finished, the unloading bracket drives the workpiece to fall down after the cutting is finished, then the workpiece is turned over and unloaded, and the machine tool works in a circulating mode. However, the discharging structure and operation are not described in detail in this patent, and it is not known how the profile clamped on the left full stroke rear chuck is discharged, and particularly, in the case of a long profile to be cut, the profile is very easily clamped on the left full stroke rear chuck even if the left full stroke rear chuck is opened. In order to solve the technical problem, patent 201911407055.3 proposes a solution that when a long pipe needs to be cut (for example, the length of the cut pipe is 2 to 4 m), the front chuck unit moves to a position close to one end of the blanking clamping unit, the middle chuck unit moves to a position where the laser cutting head cuts to play a role of clamping and supporting, and the front chuck unit moves to the middle of the pipe to be cut to clamp the pipe; when blanking, the front chuck unit clamps the pipes to move forwards until the end parts of the pipes stretch into the blanking clamping unit, then the end parts of the pipes are clamped through the blanking clamping unit, the front chuck unit moves backwards to separate from the pipes, then the blanking supporting plate unit rises to support the pipes, the blanking clamping unit loosens the pipes, and the cut pipes turn over along with the falling of the blanking supporting plate unit to realize blanking.

The technical scheme in the patent 201911407055.3 is analyzed, and the front chuck unit comprises at least three displacements in the blanking process, and firstly, the clamped section is conveyed forwards to the blanking clamping unit; second, moving back out of the tubing; and thirdly, resetting to prepare for the cutting work of the next period. Therefore, the blanking operation is complicated, the cutting work cannot be carried out before the front chuck unit is reset, and the cutting efficiency is low.

Aiming at the defects of the prior art, the invention provides cutting equipment with a double-clamping combination on a discharging side, which comprises a bottom frame, wherein a cutting head for mounting a cutting knife is arranged on the bottom frame; the cutting machine is characterized in that a sliding table is arranged on the base frame, the sliding table is positioned at the downstream of the cutting head, a downstream cutting clamp and an ejection clamp are arranged on the sliding table, the downstream cutting clamp is positioned at the downstream of the cutting head, the ejection clamp is positioned at the downstream of the downstream cutting clamp, the sliding table is used for carrying the downstream cutting clamp and the ejection clamp to move relative to the cutting head, the downstream cutting clamp does not move relative to the sliding table, and the ejection clamp can move relative to the sliding table; the downstream cutting clamp and the discharging clamp have the same clamping central axis, the downstream cutting clamp is used for clamping the section bar at the downstream of the cutting head when the section bar is cut, and the discharging clamp is used for matching, not only matching and clamping the section bar released by the downstream cutting clamp, but also matching and dragging the released section bar away from the downstream cutting clamp; the discharging clamp comprises a pair of clamping arms capable of moving relatively, and when the pair of clamping arms are opened, an opening is formed between the pair of clamping arms, so that a clamped section can pass through the opening and fall downwards.

Thus, the L-shaped bearing frame can better provide stable support for the cutting head 2, the downstream cutting clamp 3, the discharging clamp 4 and the material supporting device 5. In addition, the profile falling from the discharging clamp 4 can be received by the inclined discharging table 13. Secondly, most of the scraps formed during cutting fall onto the inclined blanking table 13, so that the scraps are convenient to clean. The embodiment of the material holder 5 is various, for example, it may be a V-shaped material holder or a holder capable of holding a profile, in this embodiment, the material holder 5 is a chuck type holder.

The cutting head 2 is positioned between the material supporting device 5 and the downstream cutting clamp 3 and is used for cutting a section bar b. Thirdly, at this time, since the profile b is already located in the clamping range of the discharging clamp 4, it is not necessary to move the downstream cutting clamp 3 to the discharging clamp 4 to convey the profile b in order to make the discharging clamp 4 have access to the cut profile b, at this time, the pair of clamping arms 41 of the discharging clamp 4 clamps the profile b, the downstream cutting clamp 3 releases the profile b, then the discharging clamp 4 clamps the profile b to move in the downstream direction, and after the discharging clamp 4 pulls the profile b away from the downstream cutting clamp 3, an opening is opened between the pair of clamping arms (41, 41 a) so that the profile b can fall down through the opening 42. And in the fourth part, the rodless cylinder drives the discharging clamp 4 to move and reset, and in the process, the downstream cutting clamp 3 is not hindered from clamping the section bar to start the next period of cutting work. Therefore, the blanking operation of the cutting equipment is simple, and the cutting efficiency is high.
