Description

Technical Field

[0001] This utility model relates to the field of band sawing technology, specifically a CNC variable speed band sawing machine for zero-tailing of sheet metal. Background Technology

[0002] Currently, in the sheet metal processing industry, band saws are widely used as an important processing equipment in the cutting of various sheet metals. However, traditional band saws often have some problems when cutting sheet metals. These problems not only affect cutting efficiency and accuracy, but also increase production costs and material waste.

[0003] In traditional band saws, the stability of the saw band is poor during the cutting process. Due to the lack of effective limiting and support structures, the saw band is prone to vibration and deviation during cutting, resulting in uneven cut surfaces and even cutting failures. This not only affects cutting efficiency but also increases scrap rate and production costs.

[0004] Therefore, we propose a CNC variable speed band saw for zero-tailing of sheet metal. By designing unique clamping components, positioning frames, and limit support components, we achieve stable cutting of the saw band. Summary of the Invention

[0005] The purpose of this utility model is to provide a CNC variable speed band saw for cutting sheet metal with zero tail material, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC variable speed band saw for zero-tailing of sheet metal, comprising a workbench, with slides fixedly installed on both sides of the bottom of the workbench by bolts, a fixed seat slidably installed inside the slides, and a positioning frame fixedly installed on the side wall of the fixed seat by bolts, the positioning frame being a concave positioning frame, the top and bottom of the positioning frame being installed on both sides of the sawing band respectively, the top of the positioning frame being movable horizontally by a limiting support component, and a clamping component installed on the top of the workbench, the clamping component corresponding to the sawing band.

[0007] Optionally, the limiting support assembly includes a support fixedly installed on one side of the top of the workbench by bolts, limiting sleeves fixedly installed on both sides of the top of the support, and limiting rods slidably installed in the two sets of limiting sleeves, with one side of the two sets of limiting rods fixedly installed to the side wall of the positioning frame.

[0008] By adopting the above technical solution, the workpiece can be cut.

[0009] Optionally, a cutting groove is provided in the middle of the workbench. The cutting groove is horizontal and corresponds to the sawing band.

[0010] By adopting the above technical solution, it corresponds to the sawing strip.

[0011] Optionally, a hydraulic push rod is fixedly installed on one side of the slide, and the other end of the hydraulic push rod is fixedly installed to the side wall of the fixed seat.

[0012] By adopting the above technical solution, the fixed seat can be moved horizontally.

[0013] Optionally, the clamping assembly includes an electric push rod fixedly installed at one end of the top of the workbench by bolts, a push plate fixedly installed at the other end of the electric push rod, and a stop fixedly installed on one side of the middle of the support, wherein the stop and the push plate correspond to each other.

[0014] By adopting the above technical solution, the workpiece can be clamped.

[0015] Optionally, a waste liquid box is snapped onto one side of the slide, the top of the waste liquid box is open, and the waste liquid box corresponds to the cutting groove.

[0016] By adopting the above technical solution, coolant can be collected.

[0017] Optionally, a conveyor seat is fixedly installed on one side of the workbench by bolts, and brackets are fixedly installed on both sides of the bottom of the conveyor seat. A conveyor roller is rotatably installed inside the conveyor seat.

[0018] By adopting the above technical solution, the workpiece can be transported.

[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0020] The technical solution of this application uses an electric push rod inside the clamping assembly to firmly clamp one end of the workpiece, and then drives a hydraulic push rod on one side of the slide to push the fixed seat inside the slide to move horizontally. Since the side wall of the fixed seat is fixedly installed with the positioning frame, it can synchronously drive the sawing band on the positioning frame to move horizontally, and cut one end of the workpiece to a fixed length. In addition, the top of the positioning frame is slidably connected to the upper limit sleeve of the support through a limit rod, which can limit and support the top of the positioning frame, ensuring that the sawing band installed inside the positioning frame can smoothly cut one end of the workpiece.

[0021] A push plate is fixedly installed at the other end of the electric push rod, and a stop is fixedly installed on one side of the middle of the support. Before the operator pushes the workpiece to one side of the workbench, the electric push rod is first driven to push the push plate away from the stop, ensuring that there is enough space between the stop and the push plate. After the workpiece is pushed between the stop and the push plate, the electric push rod is driven again to push the push plate, so that the push plate and the stop firmly clamp one side of the workpiece, ensuring the stability and firmness of the workpiece when it is cut.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a CNC variable speed sawing machine for zero-tail material cutting of sheet metal, comprising a workbench 1, with slides 11 fixedly installed on both sides of the bottom of the workbench 1 by bolts, a fixed seat 12 slidably installed inside the slides 11, and a positioning frame 13 fixedly installed on the side wall of the fixed seat 12 by bolts. The positioning frame 13 is concave, and its top and bottom are respectively installed on both sides of the sawing band 14. The top of the positioning frame 13 moves horizontally through a limiting support component. A [missing information - likely a component or component] is installed on the top of the workbench 1. The clamping assembly corresponds to the sawing band 14. The limiting support assembly includes a support 2 fixedly installed on one side of the top of the workbench 1 by bolts, limiting sleeves 21 fixedly installed on both sides of the top of the support 2, and limiting rods 22 slidably installed in the two sets of limiting sleeves 21. One side of the two sets of limiting rods 22 is fixedly installed to the side wall of the positioning frame 13, which can cut the workpiece. A cutting groove is opened in the middle of the workbench 1. The cutting groove is transverse and corresponds to the sawing band 14.

[0028] By driving the electric push rod 3 inside the clamping assembly to firmly clamp one end of the workpiece, and then driving the hydraulic push rod 23 on one side of the slide 11 to push the fixed seat 12 inside the slide 11 to move horizontally. Since the side wall of the fixed seat 12 is fixedly installed with the positioning frame 13, it can synchronously drive the sawing band 14 on the positioning frame 13 to move horizontally and cut one end of the workpiece to a fixed length. In addition, the top of the positioning frame 13 is slidably connected to the upper limit sleeve 21 of the support 2 through the limit rod 22, which can limit and support the top of the positioning frame 13, ensuring that the sawing band 14 installed inside the positioning frame 13 can smoothly cut one end of the workpiece.

[0029] In this technical solution, the clamping assembly includes an electric push rod 3 fixedly installed at one end of the top of the workbench 1 by bolts, a push plate 31 fixedly installed at the other end of the electric push rod 3, and a stop 32 fixedly installed on one side of the middle of the support 2. The stop 32 and the push plate 31 correspond to each other and can clamp the workpiece.

[0030] Before the operator pushes the workpiece to one side of the workbench 1, the electric push rod 3 is driven to push the push plate 31 away from the abutment 32, ensuring that there is enough space between the abutment 32 and the push plate 31. After the workpiece is pushed between the abutment 32 and the push plate 31, the electric push rod 3 is driven again to push the push plate 31, so that the push plate 31 and the abutment 32 firmly clamp one side of the workpiece, ensuring the stability and firmness of the workpiece when it is cut.

[0031] In this technical solution, a waste liquid box is snapped onto one side of the slide 11. The top of the waste liquid box is open, and the waste liquid box corresponds to the cutting groove, which can collect the coolant.

[0032] As the sawing band 14 on the positioning frame 13 continuously cuts the workpiece, the coolant continuously cools the workpiece and the sawing band 14. A large amount of coolant falls down along the cutting groove. With the waste liquid box installed at the bottom of the workbench 1, a large amount of coolant can be collected to prevent it from spilling on the ground.

[0033] In this technical solution, a conveyor seat 33 is fixedly installed on one side of the workbench 1 by bolts. Supports 34 are fixedly installed on both sides of the bottom of the conveyor seat 33. A conveyor roller 35 is rotatably installed inside the conveyor seat 33, which can convey the workpiece.

[0034] By placing the workpiece on the conveyor seat 33 and using the multiple sets of conveyor rollers 35 on the conveyor seat 33, one end of the workpiece can be pushed to one side of the workbench 1 with minimal effort.

[0035] In this technical solution, a hydraulic push rod 23 is fixedly installed on one side of the slide 11, and the other end of the hydraulic push rod 23 is fixedly installed on the side wall of the fixed seat 12, which can push the fixed seat 12 to move horizontally.

[0036] By driving the hydraulic push rod 23 on one side of the slide 11, the fixed seat 12 inside the slide 11 is moved horizontally.

[0037] In use, the workpiece is first placed on the conveyor seat 33. With the help of multiple sets of conveyor rollers 35 on the conveyor seat 33, one end of the workpiece can be pushed to one side of the workbench 1. The electric push rod 3 inside the drive clamping assembly firmly clamps one end of the workpiece. Simultaneously, the hydraulic push rod 23 on one side of the slide 11 is driven, pushing the fixed seat 12 inside the slide 11 to move horizontally. Since the side wall of the fixed seat 12 is fixedly installed with the positioning frame 13, the sawing band 14 on the positioning frame 13 can be moved horizontally synchronously to cut one end of the workpiece to a fixed length. Furthermore, the top of the positioning frame 13 is slidably connected to the upper limit sleeve 21 of the support 2 via the limit rod 22, allowing for precise positioning. The top of the positioning frame 13 is limited and supported to ensure that the sawing band 14 installed inside the positioning frame 13 can smoothly cut one end of the workpiece. At the same time, a push plate 31 is fixedly installed at the other end of the electric push rod 3, and a stop seat 32 is fixedly installed on one side of the middle of the support 2. Before the operator pushes the workpiece to one side of the workbench 1, the electric push rod 3 is driven to push the push plate 31 away from the stop seat 32 to ensure that there is enough space between the stop seat 32 and the push plate 31. After the workpiece is pushed between the stop seat 32 and the push plate 31, the electric push rod 3 is driven again to push the push plate 31, so that the push plate 31 and the stop seat 32 firmly clamp one side of the workpiece to ensure the stability and firmness of the workpiece when it is cut.
