Description

Technical Field

[0001] The utility model belongs to the field of cutting, and in particular relates to a wire cutting device. Background Art

[0002] With the continuous development of China's railways, the requirements for turnout pads are becoming increasingly stringent, especially on heavy-load and high-speed lines. Ordinary rubber pads, after short-term use, can suffer from a series of problems, including pressure damage, aging and deterioration, loss of elasticity, and decreased fastener pressure. These problems exacerbate the impact of trains, worsen the working environment of rails, sleepers, and the trackbed, and directly impact the service life of rails and sleepers. Currently, polyurethane elastic pads are widely used to replace ordinary rubber pads. Currently, polyurethane pads are mainly cut using blade cutting and solid knife punching. These methods have the following shortcomings: 1) Blade cutting and solid knife punching require frequent tool changes when cutting different specifications of polyurethane pads, resulting in low cutting efficiency; 2) Blade cutting and solid knife punching methods have low cutting accuracy and poor stability; 3) Blade cutting and solid knife punching methods have high tool cost, long processing cycles, and short service life. Therefore, a device with high cutting efficiency, high stability, and low cost for cutting polyurethane pads is currently needed. Utility Model Content

[0036] The wire rack mechanism 4 includes a bracket 41, at least two wire wheels 42 arranged on the bracket 41, a cutting wire 43 wound around the at least two wire wheels 42, and a rotary drive mechanism 44 for driving at least one of the wire wheels 42 to rotate. The rotary drive mechanism 44 drives the wire wheels 42 to rotate, so that the cutting wire 43 runs at a high speed. Preferably, the rotary drive mechanism 44 adopts a rotary motor.

[0037] The cutting line 43 and the workpiece support 3 can move relative to each other, that is, the cutting line 43 can be fixed, and the workpiece support 3 can move the workpiece 5 toward the cutting line 43 for cutting, or the workpiece support 3 and the workpiece 5 can be fixed, and the wire rack mechanism 4 can drive the cutting line 43 to move toward the workpiece 5 for cutting, so that the high-speed cutting line 43 contacts the workpiece 5 for cutting;

[0038] A gap is provided on the workpiece support position 3, and the cutting line 43 can enter and exit the gap, and then when the cutting line 43 and the workpiece support position 3 move relative to each other, the cutting line 43 can cut the workpiece 5 through the gap. At this time, it can be ensured that the two sides of the workpiece 5 being cut are not in a suspended state during the cutting process, thereby ensuring the stability of the cutting. At the same time, the cutting line 43 can also cut the workpiece protruding from the side of the workpiece support position 3, thereby ensuring the flexibility of cutting. When there are multiple gaps, and the cutting line 43 and the workpiece support position 3 can move relative to each other laterally, the workpiece 5 can be cut in multiple sections, thereby improving the cutting flexibility of the wire cutting device.

[0039] The wire cutting equipment provided by the present invention cuts the workpiece 5 by the high-speed operation of the cutting wire 43, with high cutting efficiency, high stability and low cost. By arranging a gap on the workpiece support position 3, the workpiece 5 can be stably cut off, thereby improving the flexibility of cutting.

[0040] In one embodiment, there are four wire wheels 42, which are arranged in a rectangular shape. At this time, the spacing between the left and right sides of the cutting line 43 can be increased, thereby increasing the cutting stroke of the cutting line 43. When the workpiece 5 is set in the middle of the left and right cutting lines 43, both the left and right sides of the cutting line 43 can be used for cutting, thereby improving the cutting efficiency.

[0041] In one embodiment, the bracket 41 includes a vertical rod 411 and two horizontal rods 412 spaced apart on the vertical rod 411, wherein the vertical rod 411 is used to connect the bracket 41 and the base 1, and the horizontal rod 412 is used to install the wire wheel 42; preferably, one side of the horizontal rod 412 is fixed to the vertical rod 411, so that the other side of the horizontal rod 412 is protruded and suspended, so that the horizontal rod 412 and the wire wheel 42 and the cutting line 43 on this side are in a protruding suspended structure, which facilitates the cutting line 43 to enter and exit the interval and reduces the obstruction of the two sides of the interval to the suspended structure;

[0042] The wire pulleys 42 are provided at both ends of the horizontal rod 412, i.e., two wire pulleys 42 are provided on one horizontal rod 412.

Preferably, the position of the horizontal rod 412 on the vertical rod 411 is adjustable, and the position of the wire pulleys 42 on the horizontal rod 412 is also adjustable, thereby facilitating adjustment of the height and spacing of the cutting lines 43.

[0043] In one embodiment, the wire rack mechanism 4 is symmetrically provided with two groups along the X direction. The brackets 41 of the two groups of the wire rack mechanisms 4 can be moved along the X direction on the base 1. The two groups of wire rack mechanisms 4 can be provided so that both sides of the workpiece 5 can be cut simultaneously. On the one hand, the cutting efficiency can be improved, and on the other hand, the force on both sides of the workpiece 5 can be ensured to be uniform during simultaneous cutting. The two groups of wire rack mechanisms 4 can be moved along the X direction on the base 1. On the one hand, the position of the wire rack mechanism 4 relative to the workpiece 5 can be adjusted, and the cutting position can be adjusted, thereby performing multiple cuts on the workpiece 5. On the other hand, the two groups of wire rack mechanisms 4 can be controlled to move closer to or farther away from each other, thereby adjusting the cut distance between the two sides of the workpiece 5.

[0044] The workpiece support 3 can move along the Y direction on the base 1. In this case, the workpiece support 3 can move the workpiece 5 toward the wire rack mechanism 4, thereby achieving relative displacement of the workpiece 5 and the cutting line 43. Preferably, the workpiece support 3 is located between the two wire rack mechanisms 4. Preferably, the X direction and the Y direction are perpendicular to each other.

[0045] In one embodiment, an X-direction slide rail assembly 11 is provided on the base 1, and the bracket 41 is provided on the X-direction slide rail assembly 11, thereby improving the smoothness of the movement of the wire rack mechanism 4 in the X direction and simplifying the adjustment difficulty of the wire rack mechanism 4 in the X direction. Preferably, the lower end of the vertical rod 411 on the bracket 41 is connected to the X-direction slide rail assembly 11;

[0046] The base 1 is further provided with a Y-direction slide rail assembly 12 , and the workpiece support 3 is provided on the Y-direction slide rail assembly 12 , thereby improving the smoothness of the workpiece support 3 moving in the Y direction and simplifying the adjustment difficulty of the workpiece support 3 in the X direction.

[0047] In one embodiment, the base 1 is provided with an X-direction linear drive mechanism 13, and the output end of the X-direction linear drive mechanism 13 is connected to the bracket 41 to facilitate active control of the position of the wire rack mechanism 4.

In this embodiment, the mounting table 31 is connected to the Y-direction slide rail assembly 12, and the upper end of the support frame 32 is used to set up the workpiece. Preferably, the support frame 32 is an I-shaped structure, the lower end of the support frame 32 is detachably connected to the mounting table 31 by bolt fasteners, and the platform at the upper end is used to support the workpiece 5. The workpiece 5 is set up on the upper surface of the support frame 32. In this embodiment, by detachably providing multiple support frames 32, it can be used to facilitate adaptation to the type and model of the supported workpiece 5. The installation stability of the workpiece 5 is improved.

[0050] In one embodiment, the support frame 32 is provided with a workpiece clamping device 2. Preferably, the workpiece clamping device 2 includes a clamping mounting frame and a Z-direction linear drive mechanism provided on the clamping mounting frame. The Z-direction linear drive mechanism can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, thereby clamping the workpiece 5 mounted on the support frame 32 to prevent the workpiece 5 from moving during the cutting process, resulting in cutting deviation. In actual use, the workpiece clamping device 2 can be provided on the support frames 32 on both sides, or a workpiece clamping device 2 can be provided on each support frame 32.

[0051] In one embodiment, a gap is formed between two adjacent support frames 32. In this embodiment, the size, number, and position of the gap can be easily adjusted, thereby facilitating adjustment of the cutting position of the workpiece 5, enabling close-spaced cutting of the workpiece 5 while ensuring stable support for the workpiece 5. Preferably, the gap between two adjacent support frames 32 is greater than the thickness of the suspended structure of the two horizontal rods 412 and the wire wheel 23, so that the horizontal rods 412 and the wire wheel 23 can enter and exit the gap between the two adjacent support frames 32 without obstruction, thereby achieving multi-section cutting of the workpiece 5.

[0052] In one embodiment, the cutting line 43 is a diamond wire to ensure the structural stability of the cutting line 43 .
