Description

Technical Field

[0001] This utility model relates to the field of cast steel parts technology, specifically a gate cutting device for processing cast steel parts. Background Technology

[0002] After the production of cast steel parts is completed, it is often necessary to separate the sprue cup from the casting using a specific cutting device. Most existing sprue cutting devices for cast steel parts involve a worker placing the workpiece to be cut on the end face of a worktable and fixing it, then starting the cutting equipment, which consists of a cutting blade and a drive source, to cut the casting. Existing sprue cutting devices for cast steel parts (Announcement No.: CN222985696U) exhibit at least the following defects in use:

[0003] The above-mentioned solution, by setting up components such as a placement plate, pressure plate, spring, rack, rotating rod, and push plate, allows workers to cut casting gates by simply placing the workpiece to be cut in the fixed groove inside the placement plate and starting the cutting equipment and motor. However, in actual use, the cutting process generates high temperatures on the surface of the cast steel part. These high temperatures cause a significant temperature gradient and thermal stress in the connection area between the gate and the casting. If the material has a high tendency to air quench or poor thermal conductivity, the rapid cooling and heating of the material in a localized area can easily induce micro or even macro cracks, affecting the quality of the product. Therefore, a gate cutting device for processing cast steel parts is needed. Utility Model Content

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] A gate cutting device for processing cast steel parts includes a cutting seat 301. A material passage frame 101 is fixedly connected to the top side of one end of the cutting seat 301, and a receiving slope 302 is formed on the top side of the other end of the cutting seat 301. One side of the receiving slope 302 extends to the outside of the cutting seat 301, and a discharge channel 304 is fixedly connected to the side of the cutting seat 301 facing the extension direction of the receiving slope 302. The top surface of the discharge channel 304 and the surface of the receiving slope 302 are smoothly connected. Multiple support feet 307 are fixedly connected to the bottom side of the cutting seat 301. The finished cast steel parts after being cut fall into the receiving slope 302 and slide down into a collection device through the discharge channel 304, facilitating subsequent processing by the operator to obtain the finished product.

[0024] A heating coil 105 is fixedly wound around the inner wall of the material passage frame 101. The operation of the heating coil 105 heats the cast steel part passing through the material passage frame 101, facilitating the gate cutting process. A receiving platform 106 is fixedly connected to the bottom inner wall of the material passage frame 101. Multiple feeding rollers 109 are rotatably connected to the top side of the receiving platform 106. The rotation direction of all feeding rollers 109 is consistent with the extension direction of the material passage frame 101. The rotation of the feeding rollers 109 allows the material to be transported along the material passage frame 101. In this embodiment, the power source for material transport is not limited, as long as it can drive the cast steel part to move along the material passage frame 101.

[0025] A sliding side frame 107 is fixedly connected to each side of the receiving platform 106. A rotating ring 108 is rotatably connected between the inner walls of each sliding side frame 107. The bottom inner wall of the rotating ring 108 is flush with the top surface of the feeding wheel 109. A cutting table 104 is fixedly connected to the top of the side of the material feeding frame 101 facing a receiving slope 302. A cutting device 103 is fixedly connected between the inner walls of the cutting table 104. In this embodiment, the cutting device 103 is a thermal cutting method such as gas cutting or plasma cutting. Since cast steel parts are generally not solid parts and have internal cavities, they can often only be cut off from the outer wall. By setting the rotating ring 108, the rotation of the cast steel part is supported. When the cutting device 103 is running at a lower power, the rotation of the cast steel part cuts the cast steel part.

[0026] A top platform 102 is fixedly connected to the top side of the feeding frame 101. A clamping frame 201 is fixedly connected to the top of one side of the top platform 102. A clamping and fixing machine 202 is fixedly connected to the top side of the clamping frame 201. A lifting rod 203 is fixedly connected to the output end of the clamping and fixing machine 202. The bottom end of the lifting rod 203 passes through the top platform 102 and extends into the interior of the feeding frame 101. A clamping top frame 205 is fixedly connected to the bottom end of the lifting rod 203. The clamping top frame 205 is directly opposite the receiving platform 106. A clamping rotating wheel 206 is rotatably connected to the bottom center of the clamping top frame 205. A set of clamping feeding wheels 204 are rotatably connected between the inner walls of the two ends of the clamping top frame 205. The rotation direction of the clamping rotating wheel 206 is perpendicular to the extension direction of the feeding frame 101, and the rotation direction of all clamping feeding wheels 204 is consistent with the extension direction of the feeding frame 101. In this embodiment, the cast steel part is fixed by lowering the clamping top frame 205. In this embodiment, the cast steel part being processed is cylindrical. The cast steel part is supported by the clamping feeding wheel 204 to move along the material passing frame 101, and the rotation of the cast steel part is supported by the clamping rotating wheel 206.

[0027] A transmission frame 306 is fixedly connected to the side of the cutting seat 301 facing away from the receiving slope 302. A transmission wheel 303 is rotatably connected between the inner walls of the transmission frame 306. The top outer edge of the transmission wheel 303 is flush with the bottom inner edge of the rotating ring 108. In this embodiment, the surface of the transmission wheel 303 is provided with fine friction ridges to enhance the friction generated when the bottom surface of the cast steel part of the transmission wheel 303 contacts the surface. Thus, the rotation of the transmission wheel 303 drives the rotation of the cast steel part. A rotary motor 305 is fixedly connected to the outer side of the transmission frame 306, and the output end of the rotary motor 305 is fixedly connected to the transmission wheel 303.

[0028] It should be noted that this utility model, as a gate cutting device for processing cast steel parts, uses a material feeding frame 101 and a receiving platform 106 provided in the material feeding frame 101 to send the cast steel part to be processed to the bottom of the cutting device 103 for processing. At the same time, heating coils 105 are provided between the inner walls of the material feeding frame 101 to heat the cast steel part passing through the material feeding frame 101. This results in a smaller temperature change in the cast steel part during cutting, avoiding large temperature gradients and thermal stress, thus protecting the cast steel part, preventing cracks from forming during hot cutting, and improving the quality of the cut cast steel part.
