Description

Technical Field

[0001] The utility model relates to the technical field of headrest support rod grooving devices, in particular to a headrest support rod grooving device. Background Art

[0002] The headrest strut notching device is a key piece of equipment used in the manufacture of headrest struts. This device is primarily used in the production line of automotive headrests. Its purpose is to create specific grooves or openings in the struts. These grooves or openings allow the headrest to be adjusted up and down within a certain range to accommodate passengers of varying heights and sitting postures. They also serve to secure the headrest, ensuring it does not easily move during impact, thereby improving safety. They also facilitate the connection of the headrest struts to other components, such as the seat back, ensuring a secure fit. Existing headrest strut notching devices secure the struts with grooves, but due to dimensional deviations in the machined struts, the grooves do not fit snugly. When the cutter assembly cuts the struts, it applies a thrust force, causing the struts to shift within the grooves. This prevents the cutter assembly from accurately cutting the struts, resulting in the notches not meeting processing requirements. Utility Model Content

DETAILED DESCRIPTION

[0041] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0042] like Figures 1 to 5 As shown, the utility model is a headrest support rod grooving device, comprising:

[0043] Lower mold assembly 1; abutment 2, which is slidably set on the lower mold assembly 1, and the abutment 2 is movably abutted against the headrest support rod; upper mold assembly 3, which is movably abutted against the lower mold assembly 1; knife row assembly 4, which is movably inserted on the upper mold assembly 3, and is used for cutting the headrest support rod; pushing member 5, which is slidably set on the upper mold assembly 3, and the pushing member 5 is movably abutted against the abutment 2.

[0044] like Figure 1 As shown, the cutter row assembly is provided with a punch for cutting the headrest support rod. The lower die assembly of the notching device is fixed. When the upper die assembly moves down and abuts against the lower die assembly, the upper die assembly 3 and the lower die assembly 1 are closed. The upper die assembly 3 drives the pusher 5 to move down, so that the pusher 5 pushes the abutting member 2 to move, thereby making the abutting member 2 and the headrest support rod abut against each other and applying a thrust to the headrest support rod. At the same time, the cutter row assembly 4 cuts the headrest support rod and applies a thrust in the opposite direction to the headrest support rod. The two thrusts act on the headrest support rod to prevent the headrest support rod from deviating in the groove 7, ensuring that the cutter row assembly 4 can accurately cut the headrest support rod, so that the punching after processing meets the processing requirements.

[0045] The abutment member 2 of this solution also includes:

[0046] The first slider 210 is slidingly arranged on the lower mold assembly 1; the first abutting portion 220 is arranged on the first slider 210; the first elastic block 230 is arranged on the first abutting portion 220, and the first elastic block 230 is used to press against the side wall of the headrest support rod; the second slider 240 is slidingly arranged on the lower mold assembly 1; the second abutting portion 250, the second abutting portion 250 is arranged on the second slider 240; the second elastic block 260, the second elastic block 260 is arranged on the second abutting portion 250, and the second elastic block 260 is used to press against the side wall of the headrest support rod; the connecting rod 270, one end of the connecting rod 270 is inserted on the first slider 210, and the end of the connecting rod 270 away from the first slider 210 is inserted on the second slider 240.

[0047] When the upper mold assembly 3 and the lower mold assembly 1 are closed, the upper mold assembly 3 drives the pusher 5 downward, causing the pusher 5 to abut against the first abutting portion 220 and exerting a thrust on the first abutting portion 220. Under the action of this thrust, the first slider 210 drives the first abutting portion 220 and the first elastic block 230 to move on the lower mold assembly 1, causing the first elastic block 230 to abut against one end of the headrest support rod and exerting a thrust on the headrest support rod. Simultaneously, the first slider 210 drives the connecting rod 270 to move, causing the connecting rod 270 to move the second slider 240, which in turn drives the second elastic block 260 to move, causing the second elastic block 260 to abut against the other end of the headrest support rod and exert a thrust thereon.

[0048] When the upper mold assembly 3 and the lower mold assembly 1 are opened, the upper mold assembly 3 drives the pusher 5 upward, separating the pusher 5 from the first abutting portion 220. The first elastic block 230 elastically deforms, driving the first abutting portion 220 and the first slider 210 to reset, so that the first slider 210 drives the connecting rod 270 to reset. Simultaneously, the second elastic block 260 elastically deforms, driving the second abutting portion 250 and the second slider 240 to reset. Because the first elastic block 230 and the second elastic block 260 are made of elastic material, they will not damage the headrest support rod when they are pressed against it.

[0049] This program also includes:

[0050] Adjusting seat 6, the adjusting seat 6 is arranged on the upper mold assembly 3, and the adjusting seat 6 is used to adjust the position of the pushing member 5; the fixed block 610, the fixed block 610 is fixedly arranged on the upper mold assembly 3, and the fixed block 610 is provided with a channel; the scale bar 620, one end of the scale bar 620 is fixedly arranged on the pushing member 5, and the end of the scale bar 620 away from the pushing member 5 can move in the channel, and the scale bar 620 is provided with scale markings; the positioning hole 630, the positioning hole 630 is arranged on the fixed block 610; the arc groove 640, the arc groove 640 is arranged on the side end of the scale bar 620.

[0051] The user can replace the abutment member 2 corresponding to the spacing of the processed headrest support rods according to the spacing of the headrest support rods. There are multiple scale marks on the scale bar 620, and each scale mark corresponds to the spacing of a headrest support rod. The user pushes the pusher 5 to move, and the pusher 5 drives the scale bar 620 to move. When the scale marks on the scale bar 620 are flush with the side end surface of the fixed block 610, the axis of the positioning hole 630 and the arc groove 640 are located on the same straight line. At this time, inserting the pin into the positioning hole 630 can fix the scale bar 620 to the fixed block 610. By changing the scale marks flush with the side end surface of the fixed block 610, the position of the pusher 5 can be adjusted so that the pusher 5 can push the abutment members 2 with different spacings, so that the abutment members 2 can be tightly pressed against the headrest support rods with different spacings.

[0052] The lower end of the pushing member 5 of this solution is provided with a first inclined surface 510 , and the first abutting portion 220 is provided with a second inclined surface 221 . The first inclined surface 510 and the second inclined surface 221 are movably abutted against each other.

[0053] When the upper mold assembly 3 and the lower mold assembly 1 are closed, the upper mold assembly 3 drives the pusher 5 downward, causing the first inclined surface 510 and the second inclined surface 221 to abut against each other. The pusher 5 exerts a downward thrust on the abutting member 2, which can be decomposed into a normal force component perpendicular to the second inclined surface 221 and a downward force. Simultaneously, the abutting member 2 receives support from the lower mold assembly 1. Under the influence of the normal force component and the support force, the abutting member 2 moves horizontally and abuts against the headrest support rod.

[0054] In this embodiment, when the upper mold assembly 3 and the lower mold assembly 1 abut, a groove 7 is formed, into which the headrest support rod is placed. The user first places the headrest support rod on the lower mold assembly 1, then closes the upper mold assembly 3 and the lower mold assembly 1, forming groove 7. Simultaneously, the pusher 5 pushes the abutting member 2, forcing the abutting member 2 and the headrest support rod into contact. The combined action of the groove 7 and the abutting member 2 secures the headrest support rod, allowing the cutter assembly 4 to cut the headrest support rod more stably.

[0055] This program also includes:

[0056] The first slide groove 8 is provided on the upper mold assembly 3 , and the push member 5 is slidably provided in the first slide groove 8 ; the second slide groove 9 is provided on the lower mold assembly 1 , and the abutting member 2 is slidably provided in the second slide groove 9 .

[0057] The user pushes the pusher 5 to move along the first chute 8, thereby adjusting the position of the pusher 5 so that the pusher 5 can push the abutting members 2 at different intervals. When the upper mold assembly 3 and the lower mold assembly 1 are closed, the upper mold assembly 3 drives the pusher 5 downward, causing the pusher 5 to push the abutting member 2 to slide along the second chute 9, thereby making the abutting member 2 and the headrest support rod press against each other.

[0058] This program also includes:

[0059] The first limit block 10 is set on the lower mold assembly 1. The first limit block 10 can be pressed against the abutment member 2 and the headrest support rod and can be movably abutted against the abutment member 2; the second limit block 11 is set on the lower mold assembly 1. The second limit block 11 can be reset due to the abutment member 2 and can be movably abutted against the abutment member 2.

[0060] When the upper mold assembly 3 and the lower mold assembly 1 are closed, the upper mold assembly 3 drives the pushing member 5 to move downward, so that the pushing member 5 pushes the abutting member 2 to move, so that the abutting member 2 and the headrest support rod are pressed against each other. At the same time, the first limit block 10 abuts against the abutting member 2 to limit the position of the abutting member 2. When the upper mold assembly 3 and the lower mold assembly 1 are opened, the upper mold assembly 3 drives the pushing member 5 to move upward, so that the pushing member 5 is separated from the first abutting portion 220. The first elastic block 230 and the second elastic block 260 undergo elastic deformation, driving the abutting member 2 to reset. When the abutting member 2 completes its reset, the second limit block 11 abuts against the abutting member 2 to limit the position of the abutting member 2.

[0061] By setting the upper mold assembly 3 and the lower mold assembly 1 to close the mold, the pushing member 5 moves downward and pushes the abutting member 2 to move, the abutting member 2 is pressed against the headrest support rod, and applies a thrust to the headrest support rod in the opposite direction to the thrust applied to the headrest support rod by the knife row assembly 4, preventing the headrest support rod from shifting in the groove 7, ensuring that the knife row assembly 4 can accurately cut the headrest support rod, so that the punching groove after processing meets the processing requirements.
