Technical Field

[0001] The utility model relates to the technical field of pipe fitting punching and cutting, in particular to a crash beam crash box cutting machine. Background Technique

[0002] A crash beam crash box is a performance box welded to both ends of the rear side of the crash beam. They can absorb the energy during low-speed impacts through the effectiveness of crushing. Before welding the crash box, a structure that forms a certain angle with the length direction of the crash box and is stepped needs to be cut at one end of the crash box, so as to increase the contact area with the crash beam during welding and the tightness during connection.

[0003] Since the angles between the stepped structures at the ends of different crash beam crash boxes and the length direction of the crash box are inconsistent, and the cutting angles of the existing cutting machines currently cannot be freely adjusted, and only by moving the product and changing the angle between the product and the cutting machine, this may cause deviation in the position of the product and affect the cutting accuracy. At the same time, during cutting, generally, the crash box is held by hand, and the cutting machine is operated to cut the crash box. The crash box will inevitably shake, which will also affect the cutting accuracy and ultimately affect the welding quality between the crash beam and the crash box. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above problems and design a crash beam crash box cutting machine, which solves the problem that the cutting angle of the crash box is uncontrollable and affects the cutting accuracy.

Detailed Description of the Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0027] Such as Figure 1 、 Figure 2As shown in the figure, a preferred embodiment of the present utility model proposes a cutting machine for a crash beam crush box. The cutting machine mainly includes a workbench 1, a linear module 8, a lifting and rotating module 11, a positioning fixture 13, a cutting mechanism 12, a housing 2 and other components arranged on the workbench 1. Among them, the linear module 8, the lifting and rotating module 11, and the positioning fixture 13 are all arranged inside the housing 2, and the housing 2 plays a role in dust prevention, isolating the internal and external spaces.

[0028] Two slide rails are arranged on the workbench 1. At the same time, there is a feeding port on one side of the housing 2. One end of the slide rail extends through the feeding port to the outside of the housing 2. A slide plate 9 is slidably connected to the slide rail, and the positioning fixture 13 is fixedly installed on the slide plate 9. The linear module 8 is horizontally fixed on the workbench 1 and is drivingly connected to the slide plate 9. By linearly driving the slide plate 9 to slide along the slide rail, the positioning fixture 13 is driven to move to both the inside and outside of the housing 2. The positioning fixture 13 moves to the outside of the housing 2 for loading, and then moves to the lower part of the cutting mechanism 12 inside the housing 2 to wait for cutting.

[0029] In this embodiment, the linear module 8 adopts a driving method combined with a motor and a lead screw. The motor drives the lead screw to rotate, and the lead screw drives the slide plate 9 to slide. In other technical solutions, a cylinder can also be used to drive the slide plate 9 to move or other linear motion methods.

[0030] As Figure 3 shown, two fixing blocks are arranged on the slide plate 9. The two fixing blocks are respectively located on both sides of the positioning fixture 13. A pressing mechanism 14 is arranged on each fixing block, which is used to press the crash beam crush box placed on the positioning fixture 13 downward to prevent it from moving during cutting.

[0031] There is a positioning groove on the positioning fixture 13, which penetrates through the front and back. At the same time, a blocking block 15 is arranged at the front end of the positioning groove. When the crash beam crush box is placed in the positioning groove, the front end of the crash beam crush box abuts against the blocking block 15 to position the crash beam crush box, and then the two pressing mechanisms 14 press the crash beam crush box tightly.

[0032] The pressing mechanism 14 is connected by a fixing seat, a pressing block and an adjusting bolt. The pressing block is connected to the upper end of the adjusting bolt, and the lower end of the adjusting bolt is threadedly connected to the fixing seat. By rotating the adjusting bolt, the pressing block moves up and down, thereby pressing the crash beam crush box downward.

[0033] As Figure 2 、 Figure 4As shown in the figure, a column 7 is provided on the workbench 1. The lifting module 10 is vertically fixed on the column 7. A slide rail is also provided on the column 7, and the slide rail is vertically distributed. A feed seat 16 is slidably connected to the slide rail and is used to install the rotation module 11. In this embodiment, the lifting module 10 also adopts a combination of an electrode and a lead screw to control the up and down movement of the feed seat 16.

[0034] A machine base 19 is provided at the top of the feed seat 16. The rotation module 11 is composed of a rotation motor 111, a reduction gear 112, and a rotating shaft 113. The reduction gear 112 is vertically fixed on the machine base 19. The output end of the motor is connected to the input end of the reduction gear 112, and the output end of the reduction gear 112 is connected to the rotating shaft 113. The lower end of the rotating shaft 113 is rotatably connected to the machine base 19 through a bearing and passes through the machine base 19.

[0035] A crank 17 and a mounting seat 18 are provided on the machine base 19. The mounting seat 18 is fixed to the bottom of the crank 17 and together with the crank 17 forms a structure similar to a "C" shape. Both the crank 17 and the mounting seat 18 are fixedly connected to the rotating shaft 113 and rotate together with the rotating shaft 113.

[0036] The cutting mechanism 12 is fixed to the bottom of the mounting seat 18. The cutting mechanism 12 is composed of a cutting motor and a blade 121. The cutting motor is horizontally fixed, and the blade 121 is fixed to the output end of the cutting motor. The blade 121 is vertically arranged. The rotation axis 113 of the blade 121 in the vertical plane is coaxial with the rotating shaft 113. Therefore, when the rotating shaft 113 drives the cutting mechanism 12 to rotate, the blade 121 always rotates along the vertical axis passing through the center of the circle as the rotation axis 113.

[0037] When the crash beam energy absorber needs to be cut, the rotation module 11 drives the cutting mechanism 12 to rotate and adjusts the angle between the blade 121 and the crash beam energy absorber. The cutting mechanism 12 moves down, and the blade 121 cuts a cutting opening at one end of the crash beam energy absorber. Then, the crash beam energy absorber is retracted a certain distance, and the blade 121 cuts another cutting opening on the crash beam energy absorber again. The heights of the two cutting openings are inconsistent and are distributed in a stepped shape. After cutting is completed, the material is discharged, and a new crash beam energy absorber is replaced.

[0038] The previously cut crash beam energy absorber is only a preliminary cut. Then, a conventional cutting machine is used to cut the remaining waste along the trajectories of the two cutting openings on the crash beam energy absorber, and finally a stepped structure is formed at the end of the crash beam energy absorber.

[0039] Such as Figure 1As shown in the figure, a dust baffle 3 is also provided at the position of the feed inlet on one side of the housing 2. A lifting cylinder 4 is provided outside the housing 2. The output end of the lifting cylinder 4 is connected to the dust baffle 3 to control the up and down movement of the dust baffle 3 to close the feed inlet and prevent dust leakage. The lower end of the dust baffle 3 has a notch for avoiding the slide rail.

[0040] There are three through holes on the front of the housing 2. Removable sealing plates 5 are provided at two of the through holes for plugging the through holes. A waste chip collection pipe 6 is provided at the other through hole. The waste chip collection pipe 6 is used to connect to the exhaust duct to extract air outward through the exhaust duct to suck out the scattered waste chips in the housing 2, playing a role in dust reduction.

[0041] When it is necessary to adjust the position of the air extraction port, only need to remove the sealing plate 5 and the waste chip collection pipe 6, reinstall the waste chip collection pipe 6 at a different through hole position, and then reseal the other two sealing plates 5.

[0042] Between the two slide rails on the workbench 1, a material leakage hole is provided at the bottom of the workbench 1. The material leakage hole is located below the slide plate 9. Large particle waste generated during the cutting process will leak out through the material leakage hole, and a container for receiving materials is placed below the material leakage hole.

[0043] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present utility model. Some changes that those skilled in the art may make to some parts thereof all reflect the principles of the present utility model and are within the protection scope of the present utility model.
