Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a cutting pressure self-adaptive loop wire cutting machine. Background Art

[0002] The working principle of the circular wire cutting machine is to use the continuously rotating cutting wire to cut the material. The cutting wire is driven by the transmission wheel. When cutting is required, the transmission wheel and the cutting wire move downward together to gradually cut the material.

[0003] At present, most conventional structures on the market only use a set of up and down movement transmission structure to achieve the up and down movement of the cutting line. However, when the cutting line contacts the material, it is easily deformed by the resistance of the material, which causes uneven cutting force on the material. Different materials have different effects on the tension of the cutting line, making it difficult to control the cutting effect. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a cutting pressure adaptive circular wire cutting machine with a reasonable structure, which can sense the tension on the cutting wire and automatically relax or tighten the cutting wire, thereby ensuring the accuracy of the cutting surface.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A cutting pressure adaptive loop wire cutting machine, comprising a waterproof workbench arranged on a frame, a cutting assembly correspondingly arranged above the waterproof workbench, and the cutting assembly comprising:

[0007] The transmission wheel set is connected to the frame with longitudinal sliding.

[0008] Cutting line, tensioned on the transmission wheel set,

[0009] The tension adjusting motor drives a transmission wheel in the transmission wheel group to reciprocate; the tension adjusting motor receives the tension signal on the cutting line at the same time.

[0010] As a further improvement of the above technical solution:

[0011] Cutting slide rails and gear rack pairs are arranged on both sides of the frame. The driving wheel set is slidably connected to the cutting slide rails and is driven to reciprocate by the gear rack pairs.

[0012] The transmission wheel group comprises a base plate, a driving wheel and a driven wheel located on the base plate; the base plate falls on the cutting slide rail; the tension adjustment motor is fixedly installed on the base plate, pushing the driven wheel to move relative to the driving wheel.

[0013] The transmission wheel set and the tension adjustment motor are respectively located on both sides of the base plate.

[0014] A through slot is provided on the base plate, and the axle of the driven wheel passes through the through slot to the side where the tension adjustment motor is located; a tension adjustment slide rail and a tension adjustment slide plate are also provided on the base plate, and the axle of the driven wheel is fixedly connected to the tension adjustment slide plate.

[0015] A cutting space for accommodating materials to be cut is reserved in the middle of the base plate, and a tension adjustment motor is fixedly installed in the middle of the base plate and above the cutting space.

[0016] The power source of the rack and pinion pair, the power source of the driving wheel, and the tension adjustment motor are independent of each other.

[0017] The waterproof workbench adopts a multi-level waterproof structure, including a sealing ring between the frame; the waterproof workbench includes a cover shell as a bearing surface and an accordion cover arranged in the cover shell.

[0018] A three-jaw chuck is arranged on the waterproof workbench, and a clamping surface of the three-jaw chuck is arranged in a horizontal plane or a vertical plane.

[0019] A rotating bearing platform is arranged on the table top of the waterproof workbench, and the material to be cut is placed on the rotating bearing platform and can rotate relative to the waterproof workbench.

[0020] The beneficial effects of the utility model are as follows:

[0021] The utility model has a compact and reasonable structure and is easy to operate. A servo cylinder is added behind the substrate as a tension adjustment motor to timely sense the pressure on the cutting line. When the pressure on the cutting line is too large, the tension adjustment motor pulls the driven wheel toward the driving wheel to reduce the tension of the cutting line. When the pressure on the cutting line is small, the tension adjustment motor pushes the driven wheel away from the driving wheel to increase the tension on the cutting line, thereby ensuring that the tension on the cutting line is always kept stable during the cutting process.

[0022] In the utility model, the tension adjustment motor for pushing and pulling the driven wheel is located above the center of the base plate, so that the forces on both sides of the driven wheel and the driving wheel on the entire base plate are more uniform.

[0023] The utility model also discloses a waterproof tooling platform, which utilizes a three-layer waterproof structure to protect the internal transmission mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The power source of the rack and pinion pair 5 , the power source of the driving wheel 302 , and the tension adjustment motor 304 are independent of each other.

[0050] The waterproof workbench 2 adopts a multi-level waterproof structure, including a sealing ring 201 between the frame 1; the waterproof workbench 2 includes a cover shell 202 as a bearing surface and an accordion cover 203 arranged in the cover shell 202.

[0051] The specific structure and working principle of the utility model are as follows:

[0052] like Figure 1 As shown in FIG. 1 , it is a schematic diagram of the whole machine of the circular wire cutting machine of the utility model, with a shell. Figure 2 and Figure 3 The figure shows the internal structure behind the hidden shell. Figure 2 Showing one side of the transmission wheel set, Figure 3 One side of the tension adjustment motor 304 is shown.

[0053] like Figure 2 As shown, a waterproof workbench 2 that can slide is provided on the frame 1, and the structure of the waterproof workbench 2 is combined with reference Figure 5-Figure 7 A sealing ring 201 is provided on the bottom surface of the waterproof workbench 2. An accordion cover 203 is used inside the waterproof workbench 2 to waterproof the transmission structure. A cover shell 202 is provided on the outermost layer, which plays the role of waterproofing and bearing material at the same time.

[0054] The working part of the frame 1 is an n-shaped structure, including steel sections on both sides. Cutting slide rails 101 are installed on the steel sections on both sides, and the base plate 4 is slidably connected to the cutting slide rails 101. A motor drives a gear rack pair 5 to realize the up and down movement of the base plate 4. The rack is installed on the side steel section, and the gear is installed on the base plate 4.

[0055] The two sides of the base plate 4 are respectively equipped with a transmission wheel group and a tension adjustment component for pushing the driven wheel 303. The driving wheel 302 and the driven wheel 303 of the transmission wheel group are located on the same horizontal line, and the cutting line 301 is tensioned. The driving wheel 302 is equipped with an active motor.
