Description

Technical Field

[0001] This utility model relates to the field of wire harness sheath production technology, and in particular to a slitting device for automotive wire harness sheath production line. Background Technology

[0002] In automotive wiring harness sheathing production lines, the slitting device is one of the key pieces of equipment in the automated production process. Its main function is to precisely cut sheathing materials or wiring harness assemblies to meet process requirements and production efficiency. The specific functions are as follows: 1) The slitting device cuts continuous automotive wiring harness sheaths to a preset length, ensuring that the dimensions of the sheath and the wiring harness match. For example, in the wire cutting process, the dimensions of the conductors and sheaths must strictly conform to the drawing requirements; the accuracy of the slitting device directly affects the quality of subsequent crimping and assembly. For wiring harnesses requiring segmented protection, the slitting device can customize the sheath length to adapt to the protection needs of different wiring harness branches. 2) In automated production lines, the slitting device is integrated with processes such as wire cutting and stripping to achieve automatic cutting of automotive wiring harness sheaths, reducing manual intervention and significantly improving production efficiency. The slitting device in the automotive wiring harness sheathing production line combines functionality, efficiency, and quality assurance. Through automated cutting, it achieves precise matching between the sheath and the wiring harness, thereby supporting the protection, sealing, and electrical performance requirements of the wiring harness.

[0003] Existing slitting devices used in automotive wiring harness sheath production lines have several shortcomings. First, they cannot provide external support for the wiring harness sheaths during the slitting process, making them prone to deformation and hindering smooth slitting. Second, they cannot perform heat sealing on the cut surfaces of the wiring harness sheaths after slitting, failing to form a sealing layer by fusing the cut edges. Therefore, it is necessary to optimize and improve the existing slitting devices used in automotive wiring harness sheath production lines. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a slitting device for automotive wiring harness sheath production lines.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A slitting device for an automotive wiring harness sheath production line includes a slitting heat-sealing assembly and adsorption-type external clamping assemblies disposed on both sides thereof.

[0007] The slitting heat sealing assembly includes a first frame, a first vertical push rod, a cutting plate, a heating ring, and a pressure block. The first vertical push rod is installed on the lower side of the upper frame plate of the first frame. The cutting plate is installed on the movable end of the first vertical push rod. The bottom end of the cutting plate is provided with a cutting edge. The heating ring is embedded in the cutting plate. The pressure block is installed on the upper side of the lower frame plate of the first frame. The pressure block has a groove that cooperates with the cutting edge.

[0008] The adsorption-type external clamping assembly includes a second frame, a suction pump, a second vertical push rod, a vertical tube, an arc-shaped adsorption cover, and a suction hose. The suction pump is installed on the outside of the second frame and has two suction ends. The second vertical push rod is symmetrically fixed on the upper and lower frame plates of the second frame. The movable end of the second vertical push rod is connected to one end of the vertical tube via a coupling. The other end of the vertical tube is installed and connected to the arc-shaped adsorption cover. The outside of the vertical tube is connected to the adjacent suction end of the suction pump via a suction hose.

[0009] Furthermore, in the slitting device for the automotive wiring harness sheath production line described above, the width of the cutting blade is greater than the outer diameter of the automotive wiring harness sheath.

[0010] Furthermore, in the slitting device for the automotive wiring harness sheath production line described above, the outer diameter of the heating ring is greater than the outer diameter of the automotive wiring harness sheath, and the inner diameter of the heating ring is smaller than the inner diameter of the automotive wiring harness sheath.

[0011] Furthermore, in the above-mentioned slitting device for automotive wiring harness sheath production line, the interior of the arc-shaped adsorption cover is provided with an arc-shaped adsorption cavity communicating with the vertical tube, and the inner side of the arc-shaped adsorption cover is evenly distributed with a plurality of adsorption holes communicating with it.

[0012] Furthermore, in the above-mentioned slitting device for automotive wiring harness sheath production line, the two ends of the arc-shaped adsorption cover are provided with outwardly extending end plates, and the two arc-shaped adsorption covers can form an adsorption area that matches the outer diameter of the automotive wiring harness sheath after docking.

[0013] Furthermore, in the slitting device for the automotive wiring harness sheath production line described above, the automotive wiring harness sheath is a cylindrical tube formed by extrusion molding of plastic material.

[0014] The beneficial effects of this utility model are:

[0015] This utility model's slitting device mainly consists of a slitting and heat-sealing assembly and adsorption-type external clamping assemblies located on both sides. On one hand, the slitting and heat-sealing assembly is rationally designed. By integrating a heating ring on the cutting plate, it can heat-seal the cut surface of the automotive wiring harness sheath after slitting, forming a sealing layer by fusing the cut edges. On the other hand, the adsorption-type external clamping assembly is rationally designed. It uses two second vertical push rods to drive the arc-shaped adsorption cover closer together and abut against the outside of the automotive wiring harness sheath. A negative pressure system composed of a suction pump, suction hose, and vertical pipe provides negative pressure to the arc-shaped adsorption cover. In this way, it can provide adsorption external support for the automotive wiring harness sheath during the slitting process, preventing deformation and ensuring the smooth progress of slitting and heat-sealing operations.
