Description

Technical Field

[0001] This utility model relates to the field of cross-cutting machine technology, and in particular to a semi-automatic cross-cutting machine for metal base plates. Background Technology

[0002] Semi-automatic cross-cutting machines are mechanical devices commonly used for cutting various materials. They combine the advantages of manual and automatic operation, have a relatively compact structure, and are suitable for the production and processing of small and medium-sized enterprises. They can cross-cut various materials such as paper, plastic sheets, leather, and thin metal sheets. The cutting speed can be adjusted as needed. While ensuring cutting quality, they also have certain cost advantages, making them popular in related industries and a powerful tool for improving production efficiency.

[0003] Existing technologies include, for example, the utility model with publication number CN213829310U. This utility model relates to the field of die-cutting machines, specifically a semi-automatic die-cutting machine. It includes a die-cutting machine body, a paper-cutting table on the top of the body, and vertical plates with their bottom ends mounted on the top of the die-cutting machine body on both sides of the paper-cutting table. A pressure plate is slidably installed between the two vertical plates. A reciprocating mechanism for driving the pressure plate to move up and down is installed at the rear end of the die-cutting machine body. Two horizontal cutting blades and two vertical cutting blades are arranged in a rectangular shape at the bottom of the pressure plate. A horizontal adjustment mechanism is also included. The adjustment mechanism is located at the bottom of the pressure plate, and both cross-cutting blades are installed at the bottom of the adjustment mechanism. The adjustment mechanism adjusts the distance between the two cross-cutting blades by rotating. The adjustment mechanism adjusts the distance between the two cross-cutting blades by rotating the screw, and the adjustment mechanism adjusts the distance between the two vertical cutting blades by sliding the sleeve. Ultimately, the adjustment of the cross-cutting blades and vertical cutting blades is more precise and convenient, and the operation is simple. However, during cutting, the operator usually manually pushes the metal base plate into the blade holder for cutting. During the cutting process, the metal base plate is prone to displacement, resulting in a skewed cut and affecting the workpiece processing quality.

[0004] To address the problem of metal base plates easily shifting, causing skewed cuts and affecting workpiece processing quality, existing technologies rely on manual handling by operators. However, this increases the difficulty of operating the equipment and leads to unstable metal base plate cuts. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where metal base plates are prone to shifting, leading to skewed cuts and affecting workpiece processing quality. Therefore, this invention proposes a semi-automatic cross-cutting machine for metal base plates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a semi-automatic cross-cutting machine for metal base plates, comprising a machine body and a propulsion device. A blade holder is mounted on the surface of the machine body. The propulsion device is disposed on the surface of the machine body and includes a guide rail. The guide rail is fixedly connected to the machine body. A slide is slidably connected to the surface of the guide rail. A threaded hole is formed on the surface of the slide. A lead screw is threadedly connected to the surface of the slide. A workpiece slot is formed on the side of the slide near the lead screw. A rack is fixedly connected to the side of the machine body near the guide rail. A workpiece slot is also formed on one side of the slide. A mounting sleeve is fixedly connected to the cutting tool. The surface of the mounting sleeve has a hole, and a servo motor is fixedly connected to the inner wall of the hole. By setting up a propulsion device, the position of the metal base plate is ensured to be stable during the cutting process, effectively reducing problems such as cutting size deviation and uneven cut caused by workpiece displacement, thus ensuring cutting accuracy and quality. At the same time, it can achieve stable and slow uniform speed propulsion, allowing the workpiece to enter the tool holder smoothly. This helps the tool holder to apply force evenly for cutting, reducing vibration and impact during cutting, extending tool life, and also improving the overall cutting effect and production efficiency.

[0007] Preferably, the drive end of the servo motor is fixedly connected to a gear, which meshes with a rack. By setting the servo motor, the servo motor has high-precision control characteristics. It can accurately drive the gear to rotate according to preset parameters, thereby accurately controlling the speed and displacement of the slide carriage sliding towards the tool holder. This ensures that the metal base plate enters the tool holder for cutting at a suitable rhythm, which helps to improve cutting accuracy and ensure that the cutting size meets the requirements.

[0008] Preferably, the rack and guide rail are symmetrically arranged, and the lead screw is located on the upper surface of the slide. By setting the guide rail, the guide rail can provide precise guidance for the sliding of the slide, ensuring that the slide moves strictly along the predetermined straight trajectory when sliding towards the tool holder, so that the workpiece can enter the tool holder for cutting accurately, which greatly improves the accuracy of the cutting position and ensures the cutting precision.

[0009] Preferably, the lead screw passes through the workpiece slot on one side of the slide, and the position of the slide corresponds to the tool holder. By setting the lead screw, the tightness can be precisely adjusted according to actual needs, and the metal base plate can be firmly fixed to ensure that the workpiece will not be displaced during the cutting process, thereby ensuring cutting accuracy and making the dimensions of the cut metal base plate meet the requirements.

[0010] Preferably, a feeding device is provided on one side of the machine body. The feeding device includes a slide ramp, which is fixedly connected to one side of the machine body. An assembly frame is fixedly connected to the side of the machine body near the slide ramp. A treadmill is rotatably connected to the surface of the assembly frame. A DC motor is fixedly connected to one side of the assembly frame. By setting up the feeding device, there is no need for manual handling of the cut metal base plate, which saves labor costs, improves overall production efficiency, and makes the feeding process more stable and orderly. This reduces the possibility of workpiece collisions and damage caused by manual feeding, and ensures the quality of the finished metal base plate.

[0011] Preferably, the drive end of the DC motor passes through the assembly frame and is fixedly connected to the clapper. The clapper is located on the upper surface of the landslide. By setting the DC motor, the DC motor has good speed regulation performance and can accurately control the rotation speed of the clapper, so that the workpiece can be clasped at a suitable rhythm, ensuring that the workpiece is pushed out of the machine body smoothly and orderly along the landslide to complete the unloading.

[0012] Preferably, there are two assembly racks, which are arranged in a mirror-symmetrical manner.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting up a propulsion device and a feeding device, during use, the metal base plate is placed into the workpiece slot, and then the lead screw is rotated. After the lead screw abuts against the metal base plate, the metal base plate is fixed. At this time, the servo motor is started, and the servo motor drives the gear to rotate. While the gear rotates, it works with the rack to drive the slide to slowly slide towards the tool holder. At the same time, the workpiece follows the slide into the tool holder, and the tool holder then cuts the workpiece. The cut metal base plate is then poured into the ramp. At this time, the DC motor drives the plate to rotate, and the plate taps the workpiece, pushing the workpiece out of the machine body along the ramp to complete the feeding. By setting up this invention, the position of the metal base plate is ensured to be stable during the cutting process, effectively reducing problems such as cutting size deviation and uneven cut caused by workpiece displacement, ensuring cutting accuracy and quality. At the same time, it can achieve stable and slow uniform speed propulsion, so that the workpiece can smoothly enter the tool holder, which helps the tool holder to apply force evenly for cutting, reducing vibration and impact during cutting, extending the tool life, and also improving the overall cutting effect and production efficiency.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a semi-automatic cross-cutting machine for metal base plates, including a machine body 1 and a propulsion device 3. A blade holder 2 is installed on the surface of the machine body 1, and the propulsion device 3 is disposed on the surface of the machine body 1.

[0022] The specific setup and function of its propulsion device 3 and unloading device 4 will be explained below.

[0023] In this implementation scheme: the propulsion device 3 includes a guide rail 31, which is fixedly connected to the machine body 1. A slide 33 is slidably connected to the surface of the guide rail 31. A threaded hole is opened on the surface of the slide 33, and a lead screw 34 is threadedly connected to the surface of the slide 33. A workpiece slot is opened on the side of the slide 33 near the lead screw 34. A rack 32 is fixedly connected to the side of the machine body 1 near the guide rail 31. An mounting sleeve 37 is fixedly connected to the side of the slide 33. A hole is opened on the surface of the mounting sleeve 37, and a servo motor 35 is fixedly connected to the inner wall of the hole on the surface of the mounting sleeve 37. By setting the propulsion device 3, the position of the metal base plate is kept stable during the cutting process, effectively reducing the problems of cutting size deviation and uneven cut caused by workpiece displacement, ensuring cutting accuracy and quality. At the same time, it can achieve stable and slow uniform speed propulsion, so that the workpiece can smoothly enter the tool holder 2, which helps the tool holder 2 to apply force evenly for cutting, reducing vibration and impact during cutting, extending the tool life, and also improving the overall cutting effect and production efficiency.

[0024] Specifically, a gear 36 is fixedly connected to the drive end of the servo motor 35. The gear 36 meshes with the rack 32. By setting the servo motor 35, the servo motor 35 has high-precision control characteristics. It can accurately drive the gear 36 to rotate according to preset parameters, thereby accurately controlling the speed and displacement of the slide 33 sliding towards the tool holder 2. This ensures that the metal base plate enters the tool holder 2 for cutting at a suitable rhythm, which helps to improve cutting accuracy and ensure that the cutting size meets the requirements.

[0025] Specifically, the rack 32 and the guide rail 31 are symmetrically arranged, and the lead screw 34 is located on the upper surface of the slide 33. By setting the guide rail 31, the guide rail 31 can provide precise guidance for the sliding of the slide 33, ensuring that the slide 33 moves strictly according to the predetermined straight trajectory when sliding towards the tool holder 2, so that the workpiece can enter the tool holder 2 for cutting accurately, which greatly improves the accuracy of the cutting position and ensures the cutting precision.

[0026] Specifically, the lead screw 34 passes through the workpiece slot on one side of the slide 33. The position of the slide 33 corresponds to the tool holder 2. By setting the lead screw 34, the tightness can be precisely adjusted according to actual needs, and the metal base plate can be firmly fixed to ensure that the workpiece will not be displaced during the cutting process, thereby ensuring the cutting accuracy and making the dimensions of the cut metal base plate meet the requirements.

[0027] Specifically, a feeding device 4 is provided on one side of the machine body 1. The feeding device 4 includes a slide 41, which is fixedly connected to one side of the machine body 1. An assembly frame 42 is fixedly connected to the side of the machine body 1 near the slide 41. A treadmill 43 is rotatably connected to the surface of the assembly frame 42. A DC motor 44 is fixedly connected to one side of the assembly frame 42.

[0028] In this embodiment, by setting up the unloading device 4, there is no need for manual handling of the cut metal base plate, which saves labor costs, improves overall production efficiency, and the unloading process is relatively stable and orderly, reducing the possibility of workpiece collisions and damages caused by manual unloading, and ensuring the quality of the finished metal base plate.

[0029] Specifically, the drive end of the DC motor 44 passes through the mounting frame 42 and is fixedly connected to the clapper plate 43, which is located on the upper surface of the landslide 41.

[0030] In this embodiment: by setting a DC motor 44, which has good speed regulation performance, the speed of the clapper 43 rotation can be precisely controlled, so that the workpiece can be clappered at a suitable rhythm, ensuring that the workpiece is pushed out of the machine body 1 smoothly and orderly along the slide 41 to complete the unloading.

[0031] Specifically, there are two assembly racks 42, which are arranged in a mirror-symmetric manner.

[0032] Working principle: By setting up the propulsion device 3 and the unloading device 4, during use, the metal base plate is placed into the workpiece slot, and then the lead screw 34 is rotated. After the lead screw 34 abuts against the metal base plate, the metal base plate is fixed. At this time, the servo motor 35 is started, and the servo motor 35 drives the gear 36 to rotate. While the gear 36 is rotating, it works with the rack 32 to drive the slide 33 to slowly slide towards the tool holder 2. At the same time, the workpiece follows the slide 33 into the tool holder 2, and the tool holder 2 then cuts the workpiece. The cut metal base plate is poured into the slide 41, and at this time the DC motor 44 drives the platen. Rotating at 43, the platen 43 taps the workpiece, pushing it out of the machine body 1 along the slide 41 to complete the unloading. By setting this utility model, the position of the metal base plate is ensured to be stable during the cutting process, effectively reducing problems such as cutting size deviation and uneven cut caused by workpiece displacement, thus ensuring cutting accuracy and quality. At the same time, it can achieve stable and slow uniform speed advancement, allowing the workpiece to enter the tool holder 2 smoothly, which helps the tool holder 2 to apply force evenly for cutting, reducing vibration and impact during cutting, extending the tool life, and also improving the overall cutting effect and production efficiency.
