Technical Field

[0001] The invention relates to the technical field of automobile parts preparation, and in particular to arc-shaped notch type forming equipment and a processing technology. Background Art

[0002] The car headrest rod is an essential component of the car as a middle headrest. It can be adjusted in multiple gears. Users can adjust it according to their actual needs. The above adjustment is through the arc groove of the car headrest rod and the gear. Generally speaking, the car headrest rod is equipped with multiple arc grooves for users to adjust;

[0003] In the preparation of the automobile headrest rod, multiple arc grooves that need to be adjusted are not opened at the same time, so arc groove grooving equipment is needed to groove the automobile headrest rod; usually the grooving equipment only has the function of opening an arc groove, and cannot remove the burrs generated during the grooving operation. In this way, after the automobile headrest rod is processed, a deburring equipment is needed to remove the burrs, resulting in low production efficiency and poor automation. It is necessary to develop an arc groove grooving automation equipment with combined grooving and deburring functions. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the present invention is aimed at the current status of the existing technology. An arc-shaped slot forming device is provided, which adopts a double linkage component to cooperate with a rolling component to perform product rolling operations in the axial direction and the X-axis direction. During the rolling operation, burrs can also be removed, and the processing efficiency is greatly improved.

[0006] (II) Technical solution

[0007] The present invention is achieved through the following technical scheme: The present invention proposes an arc-shaped slot forming device, which includes a frame, a support frame arranged in the frame, a double-linkage component and a product pressing component arranged in the support frame; the double-linkage component is connected to a rolling component for slotting operation; the double-linkage component reciprocates in the Z-axis direction and the X-axis direction through a Z-axis electric cylinder and an X-axis electric cylinder, so that the rolling component slots the car headrest rod in the product pressing component under the above-mentioned reciprocating motion.

[0008] The present invention is implemented by the following technical solution: a car headrest rod processing technology used in an arc-shaped notch forming device, comprising:

[0009] Step 1: one or more car headrest rods are placed in the lower mold;

[0010] Step 2: The push cylinder pushes the car headrest rod in the lower die to the rear position.

[0011] Step 3: The pressing electric cylinder descends, driving the upper die downward to the lower die and pressing the automobile headrest rod;

[0012] Step 4: The rolling assembly is connected to the transfer mechanism and reciprocates in the vertical and horizontal directions through the X-axis electric cylinder and the Z-axis electric cylinder. Specifically, the rolling assembly grooves the automobile headrest rod under the above reciprocating motion;

[0013] Step 5: After the rolling in step 4 is completed, the upper die and the lower die are separated by pressing the electric cylinder to lift, and the automobile headrest rod is taken out manually or by a robot;

[0014] Under the control of the electronic control component, the rolling component first starts rolling the first end of the automobile headrest rod, rolling to more than 3 / 4 of the arc groove to be opened, and then the X-axis electric cylinder and the Z-axis electric cylinder retreat and cooperate to control the rolling component to the second end of the automobile headrest rod, and then the automobile headrest rod is rolled from the second end to the starting first end through the rolling component.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] First, the product pressing assembly is used to press and fix the car headrest rod, which can press a maximum of two car headrest rods, so the two car headrest rods can be rolled into arc grooves, which is more efficient;

[0018] Second, the above-mentioned product pressing assembly can be automatically put into the processing workstation 1 by placing a set of pulleys in a set of conveying troughs, thereby improving the degree of automation and having a high degree of integration;

[0019] Third, the rolling component can be made into two rollers according to actual needs, and the two car headrest rods in the product clamping component can be rolled into an arc groove or multiple arc grooves, which can greatly improve the efficiency. In the rolling operation, a two-stage rolling method is adopted, which can not only open the arc groove operation, but also remove the burrs formed by the rolling operation.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Reference Figures 1 to 5 The present invention provides a car headrest rod processing technology used in an arc-shaped notch forming device, which includes:

[0029] Step 1: one or more automobile headrest rods are placed in the lower mold 41;

[0030] Step 2: The push cylinder pushes the automobile headrest rod in the lower mold 41 to the rear position;

[0031] Step 3: The pressing electric cylinder 9 descends, driving the upper die 42 downward to the lower die 41 and then pressing the automobile headrest rod;

[0032] Step 4: The rolling assembly 5 is connected to the transfer mechanism 30 and reciprocates in the vertical and horizontal directions through the X-axis electric cylinder 7 and the Z-axis electric cylinder 6. Specifically, the rolling assembly 5 grooves the automobile headrest rod under the above reciprocating motion;

[0033] Step 5: After the rolling in step 4 is completed, the pressing electric cylinder 9 is lifted and the upper die 42 is separated from the lower die 41, and the automobile headrest rod is taken out manually or by a robot; the rolling assembly 5, under the control of the electronic control assembly, first starts the rolling operation on the first end of the automobile headrest rod, rolling to more than 3 / 4 of the arc groove to be opened, and then the X-axis electric cylinder 7 and the Z-axis electric cylinder 6 retreat and cooperate to control the rolling assembly 5 to the second end of the automobile headrest rod, and then the automobile headrest rod is rolled from the second end to the starting first end through the rolling assembly 5; The logic of the above rolling is that after rolling 3 / 4 from one end, the subsequent 1 / 4 will not be rolled. This is to prevent the automobile headrest rod from being directly crushed and scrapped. Therefore, the 1 / 4 section is not rolled, and after the second section, a reverse rolling cycle is performed. The last rolling can first roll the entire arc groove into shape, and at the same time, the burrs in the rolling can be removed. The two major functions of rolling and deburring are combined, and the integration is high, making the operation of the finished automobile headrest rod more efficient;

[0034] Since two automobile headrest rods need to be rolled into arc grooves, the pressure of one Z-axis electric cylinder 6 is not enough for the rolling operation, so a Z-axis auxiliary electric cylinder 8 is configured; the above-mentioned rolling component 5 is connected to the transfer mechanism 30 and can provide a greater rolling force under the cooperation of the Z-axis electric cylinder 6 and the Z-axis auxiliary electric cylinder 8, so that multiple arc grooves of multiple automobile headrest rods can be rolled; specifically, the output end of the above-mentioned Z-axis auxiliary electric cylinder 8 passes through the table and cooperates with the transfer mechanism 30 and can control the transfer mechanism 30 to reciprocate in the Z-axis direction.

[0035] The above-mentioned transfer mechanism 30 reciprocates on the arc-shaped tooth track plates 33 on both sides through the feed rod 34, so that the rolling assembly 5 that reciprocates synchronously with the transfer mechanism 30 rolls out an arc-shaped groove consistent with the arc-shaped tooth track plate 33. The shape of the above-mentioned arc-shaped tooth track plate 33 is also consistent with the arc-shaped groove rolled by the automobile headrest rod.

[0036] In this embodiment, the above-mentioned product clamping component 4 can contain at most two automobile headrest rods, and arc grooves can be opened on the two automobile headrest rods at the same time. Furthermore, the above-mentioned rolling component 5 can also use a roller 52 or multiple rollers 52 to simultaneously open multiple arc grooves on the automobile headrest rod. Therefore, the present equipment can customize the product clamping component 4 and the rolling component 5 according to needs to open two automobile headrest rods and multiple arc grooves. The principle is the same as that of opening an arc groove on an automobile headrest rod. In order to improve work efficiency, at most two automobile headrest rods and multiple arc grooves can be opened. Moreover, the above-mentioned arc tooth track plate 33 can be replaced at any time, which is convenient for processing automobile headrest rods with different arc grooves for grooving operations, has better flexibility, and improves work efficiency.

Specifically, the clamping manner of the trapezoidal protrusion and the trapezoidal groove 54 is adopted to cooperate, which can improve the efficiency of installation and maintenance and facilitate daily maintenance.

[0039] The above-mentioned double-linkage component 3 reciprocates in the Z-axis direction under the control of the Z-axis electric cylinder 6, and reciprocates in the X-axis direction under the control of the X-axis electric cylinder 7. Specifically, the above-mentioned double-linkage component 3 can reciprocate in the Z-axis direction and the X-axis direction at the same time. When it needs to be explained, the above-mentioned X-axis electric cylinder 7 controls the rolling component 5 cooperating with the double-linkage component 3 to provide feeding operation in the X-axis direction, and can perform deep rolling on the arc groove of the automobile headrest rod. However, the above-mentioned Z-axis electric cylinder 6 controls the rolling component 5 cooperating with the double-linkage component 3 to provide the operation of the arc groove from the first end to the second end / the second end to the first end in the Z-axis direction. Under the control of the above-mentioned Z-axis electric cylinder 6 and the X-axis electric cylinder 7, the above-mentioned double-linkage component 3 controls the above-mentioned rolling component 5 to perform grooving operation on the automobile headrest rod.
