Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and more specifically, it relates to an adjustable bending angle automotive interior trim bending device. Background Technology

[0002] When processing automotive interior trim strips, bending machines are often used to bend the trim strips. When bending the trim strips, the trim strips need to be placed outside the limiting parts, and then the hydraulic cylinder of the bending machine is opened. The hydraulic cylinder drives the bending head to bend the trim strips into shape.

[0003] The existing application number is CN201711481633.9. This invention belongs to the field of automotive parts processing and specifically discloses a bending device for automotive interior panels. It includes a frame, a positioning section, a bending section, and a conveying section. The positioning section includes a slide rod, a pressure plate, and a base. The bending section includes a piston cylinder, a rotating shaft, and a pressing unit. A first rack is connected to the piston rod. The outer wall of the piston rod has a through hole. The piston cylinder is connected to a vortex tube. The end face of the piston cylinder away from the piston rod has an air outlet, and a second one-way valve is installed in the air outlet. A first gear meshes with the first rack on the rotating shaft. The pressing unit includes a second rack slidably connected to the frame, which meshes with the first gear. A support rod is connected to the top of the second rack, and a bending punch is connected to the support rod. The conveying section includes a belt for driving the first and second roller shafts.

[0004] Based on the above, when bending interior trim strips, many of the materials used in the process are highly elastic, causing the trim strips to easily come into contact with the bending head and fly off. Furthermore, since the bending area remains open, the flying trim strips can easily injure workers, posing a certain safety hazard. Utility Model Content

This solves the problem that, when bending interior trim, many materials are highly elastic, causing the trim to easily break off upon contact with the bending head. Furthermore, because the bending area remains open, the flying trim can easily injure workers, posing a safety hazard.

[0006] The purpose and effect of this utility model, an adjustable bending angle automotive interior trim bending device, are achieved by the following specific technical means:

[0007] An adjustable bending angle automotive interior trim strip bending device includes a bending machine body, a bending hydraulic cylinder, a bending fixing component, an adjusting drive handwheel, a bending protective component, a bending protection mechanism, and a bending adjustment mechanism. The bending hydraulic cylinder is fixedly connected to the top of the bending machine body, and a bending head structure is fixedly connected to the front end of the piston rod of the bending hydraulic cylinder. The bending fixing component is fixedly connected to the upper front end of the bending machine body, and a sliding groove structure is provided on the inner side of the bending fixing component.

[0008] Furthermore, the bending protection mechanism includes: protective guide components; two sets of protective guide components are provided, and the two sets of protective guide components are respectively fixedly connected to the upper left and right sides of the bending machine body.

[0009] Furthermore, the bending protection mechanism also includes: a protective transmission rod, a protective connecting member, and a protective drive rod; the protective transmission rod is slidably connected to the outside of the protective guide member, and long rod structures are provided at both the left and right ends of the front of the protective transmission rod; the protective connecting member is fixedly connected to the upper middle position of the protective transmission rod, and the upper end of the protective connecting member is fixedly connected to the piston rod of the bending hydraulic cylinder; two sets of protective drive rods are provided, and the two sets of protective drive rods are respectively hinged to the left and right ends of the front of the protective transmission rod, and the upper ends of the two sets of protective drive rods are hinged to the bending protection member.

[0010] Furthermore, the bending adjustment mechanism includes: a bending adjustment component; two sets of bending adjustment components are provided, and the two sets of bending adjustment components are slidably connected to the upper side of the inner side of the sliding groove of the bending fixing component.

[0011] Furthermore, the bending adjustment mechanism also includes: an adjusting guide wheel, an adjusting transmission rope, and an adjusting connecting spring; the adjusting guide wheel is rotatably connected to the lower left side of the bending machine body; the adjusting transmission rope is wrapped around the outer circumference of the adjusting guide wheel, the left end of the adjusting transmission rope is fixedly connected to a set of bending adjustment components on the left side, and the right end of the adjusting transmission rope is fixedly connected to a set of bending adjustment components on the right side; two sets of adjusting connecting springs are provided, the left ends of both sets of adjusting connecting springs are fixedly connected to a set of bending adjustment components on the right side, and the right ends of both sets of adjusting connecting springs are fixedly connected to bending fixing components.

[0012] Furthermore, the bending adjustment mechanism also includes: an adjustment transmission block and a bending adjustment screw; the adjustment transmission block is fixedly connected to the lower end of a set of bending adjustment components on the left side, and the adjustment transmission block is provided with a threaded hole structure; the bending adjustment screw is rotatably connected to the lower left side of the bending machine body, and the bending adjustment screw is coaxially fixedly connected to the right end of the adjustment drive handwheel, and the bending adjustment screw is threadedly connected to the adjustment transmission block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention, through the setting of a bending protection mechanism, places the interior trim strip above the bending fixing component. Opening the bending hydraulic cylinder causes the piston rod of the bending hydraulic cylinder to move forward, driving the protective connecting component forward. The forward movement of the protective connecting component then drives the protective transmission rod forward, which in turn drives the protective drive rod forward. This forward movement of the protective drive rod causes the bending protection component to rotate. The rotation of the bending protection component effectively protects the bending area, preventing the interior trim strip from flying off, thus protecting workers from injury and improving the overall safety of the bending machine.

[0015] This invention utilizes a bending adjustment mechanism. Rotating the adjustment drive handwheel causes the bending adjustment screw to rotate, which in turn moves the adjustment transmission block to the right. This movement of the adjustment transmission block to the right moves a set of bending adjustment components on the left side to the right as well. The rightward movement of the adjustment transmission block also pulls the adjustment transmission rope, which, under the action of the adjustment guide wheel, moves a set of bending adjustment components on the right side to the left. At this point, the two sets of bending adjustment components move in opposite directions, thus adjusting the distance between them. The interior trim strip is then placed between the two sets of bending adjustment components, facilitating bending of the trim strip at different angles and improving the overall applicability of the bending machine.

[0028] The specific usage and function of this embodiment are as follows: When bending the interior trim strip, the trim strip is placed above the bending fixing member 3.
