Description

Technical Field

[0001] This utility model relates to the technical field of cold press equipment, and in particular to a cold press equipment for prototyping with sheet metal edge trimming function. Background Technology

[0002] The cold press is a specialized piece of equipment used to press and bond boards at room temperature. It is widely used in furniture manufacturing, building materials production and other fields. The cold press applies continuous and uniform static pressure to the boards placed between the pressing plates. Under the pressure, the adhesive between the boards is fully cured or multiple layers of boards are tightly bonded together, thereby achieving the purposes of gluing, leveling and shaping.

[0003] In existing technologies, the current cold pressing machines for prototyping can only complete the cold pressing process of the sheet material and cannot simultaneously trim the edges of the sheet material. As a result, the sheet material needs to be transferred to a specialized trimming device for secondary processing after cold pressing, which reduces the overall processing efficiency. Moreover, since the sheet material may undergo slight displacement or deformation during the transfer to the trimming device after cold pressing, and the positioning benchmarks of the two processing are difficult to be completely consistent, it is easy to cause problems such as dimensional deviation or insufficient perpendicularity between the trimmed edge of the sheet material and the cold-pressed surface, which affects the final quality of the sheet material and the subsequent assembly accuracy. Therefore, it is necessary to improve the cold pressing machine for prototyping with sheet material edge trimming function to solve the above problems. Utility Model Content

[0004] In order to overcome the problem that the existing cold pressing machine for prototyping can only complete the cold pressing of the board and cannot simultaneously trim the edges, the cold-pressed board needs to be transferred to special equipment for secondary trimming. This not only increases the process flow time, but also may cause the edge to deviate from the board surface size or be insufficiently perpendicular due to slight displacement or deformation of the board during the transfer, which affects the final quality and subsequent assembly accuracy.

[0005] The technical solution of this utility model is as follows: a cold pressing machine device for sample making with edge trimming function of sheet metal, including a base, a support frame fixedly connected to the base, a top seat fixedly connected to the top of the support frame, a cold pressing component set on the base, a first motor fixedly connected to one side of the base, a lead screw rotatably connected inside the base, a first sprocket fixedly connected to the lead screw, a second sprocket fixedly connected to the lead screw, a transmission chain drivingly between the second sprocket and the first sprocket, a sliding frame slidably connected inside the base, a moving frame slidably connected inside the sliding frame, an adjusting inner rod slidably connected inside the moving frame, a fixing plate fixedly connected to the top of the adjusting inner rod, a second motor fixedly connected to one side of the fixing plate, and a trimming blade rotatably connected inside the fixing plate. The lead screw is fixedly connected to the output end of the first motor, the sliding frame is threadedly connected to the outside of the lead screw, and the trimming blade is fixedly connected to the output end of the second motor. The rotating lead screw drives the sliding frame to move, and the second motor drives the trimming blade to rotate.

[0006] Preferably, there are two sets of lead screws, which are symmetrically distributed on the base, and the first sprocket and the second sprocket are distributed on the two lead screws in sequence.

[0007] Preferably, the base has a matching groove at the corresponding position of the sliding frame, and the sliding frame slides inside the groove of the base.

[0008] Preferably, the sliding frame has a matching groove at the corresponding position of the movable frame, and the movable frame slides inside the groove of the sliding frame.

[0009] Preferably, the sliding frame is internally rotatably connected to a threaded rod, the movable frame is threadedly connected to the outside of the threaded rod, the movable frame is internally provided with a mounting bolt, the mounting bolt is located inside the adjusting inner rod, the external thread of the mounting bolt is connected with a mounting nut, and the fixed plate is fixedly connected to a protective frame on the side near the trimming blade, the trimming blade is located inside the protective frame.

[0010] Preferably, the movable frame has a matching groove at the corresponding position of the adjusting inner rod, the adjusting inner rod slides inside the groove of the movable frame, and both the adjusting inner rod and the movable frame have matching through holes at the corresponding positions of the mounting bolts. The mounting bolts are set inside the through holes of the adjusting inner rod and the movable frame. The movable frame has four sets of through holes, which are distributed on the movable frame from top to bottom.

[0011] Preferably, the cold pressing assembly includes a hydraulic telescopic rod fixedly connected inside the top seat, a pressure seat fixedly connected to the bottom of the hydraulic telescopic rod, a semi-circular block fixedly connected to the top of the pressure seat, a long rod rotatably connected inside the semi-circular block, a circular gear fixedly connected to the long rod, and a toothed plate fixedly connected to the support frame near the side of the circular gear. The pressure seat is slidably connected inside the support frame, and the circular gear meshes with the outside of the toothed plate. The pressure seat is moved by the hydraulic telescopic rod.

[0012] Preferably, the support frame has a matching groove at the corresponding position of the pressure seat, and the pressure seat slides inside the groove of the support frame.

[0013] The beneficial effects of this utility model are: 1. By adjusting the inner rod, mounting bolts, and mounting nuts, the height of the trimming blade can be flexibly adjusted according to the height of the cold-pressed sheet material, ensuring that the trimming blade and the edge of the sheet material are in a suitable processing position. Then, by rotating the threaded rod on the sliding frame, the distance between the trimming blades on both sides and the base can be adjusted to adapt to the edge trimming needs of sheets of different widths, improving the versatility of the device. Finally, by starting the second motor to drive the trimming blade to rotate, in conjunction with the first motor to drive the lead screw to rotate, the two lead screws are driven synchronously through the transmission chain, the first sprocket, and the second sprocket, causing the trimming blades on both sides to move. This achieves simultaneous edge trimming during the cold pressing process of the sheet material, eliminating the secondary processing step of transferring to a dedicated trimming equipment after cold pressing, reducing process flow time and the need for multiple sheet material handling, thereby improving overall processing efficiency and ensuring trimming accuracy, thus improving the final quality of the sheet material and the accuracy of subsequent assembly.

[0014] 2. The hydraulic telescopic rod provides power to move the pressure seat, which can output stable and adjustable pressure to ensure uniform cold pressing effect on the sheet material. The semi-circular block, long rod, and circular gear on the top of the pressure seat mesh with the toothed plate on the support frame. When the pressure seat moves up and down, the circular gear rolls along the toothed plate, providing precise guidance and limiting for the pressure seat. This effectively prevents the pressure seat from tilting or deviating during movement, ensuring the parallelism between the pressure seat and the lower pressure plate. This ensures uniform force on all parts of the sheet material and improves the quality of cold pressing. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 - Figure 5This utility model provides an embodiment of a cold pressing machine device for sample making with sheet metal edge trimming function, including a base 1, a support frame 4 fixedly connected to the base 1, a top seat 5 fixedly connected to the top of the support frame 4, a cold pressing assembly disposed on the base 1, a first motor 21 fixedly connected to one side of the base 1, a lead screw 22 rotatably connected inside the base 1, a first sprocket 23 fixedly connected to the lead screw 22, a second sprocket 24 fixedly connected to the lead screw 22, a transmission chain 25 drivingly connected between the second sprocket 24 and the first sprocket 23, a sliding frame 26 slidably connected inside the base 1, and a moving part slidably connected inside the sliding frame 26. The moving frame 28, the adjusting inner rod 29 slidably connected inside the moving frame 28, the fixed plate 212 fixedly connected to the top of the adjusting inner rod 29, the second motor 213 fixedly connected to one side of the fixed plate 212, and the trimming blade 214 rotatably connected inside the fixed plate 212, the lead screw 22 fixedly connected to the output end of the first motor 21, the sliding frame 26 threadedly connected to the outside of the lead screw 22, and the trimming blade 214 fixedly connected to the output end of the second motor 213, are all connected by the rotating lead screw 22 to move the sliding frame 26 and by the second motor 213 to rotate the trimming blade 214. The movement is achieved through the adjusting inner rod 29, the mounting bolt 210, and the mounting nut 213. The system, in conjunction with component 11, allows for flexible adjustment of the height of the trimming blade 214 based on the height of the cold-pressed sheet material, ensuring that the trimming blade 214 is in a suitable processing position with the edge of the sheet material. Furthermore, by rotating the threaded rod 27 on the sliding frame 26, the distance between the trimming blades 214 on both sides and the base 1 can be adjusted to accommodate the edge trimming needs of sheets of different widths, improving the versatility of the device. Finally, by starting the second motor 213 to drive the trimming blade 214 to rotate, in conjunction with the first motor 21 driving the lead screw 22 to rotate, the two lead screws 22 are simultaneously driven by the transmission chain 25, the first sprocket 23, and the second sprocket 24, causing the trimming blades 214 on both sides to move, thus achieving… By simultaneously trimming the edges during the cold pressing process of the sheet metal, the secondary processing step of transferring the sheet metal to a dedicated trimming device after cold pressing is eliminated. This reduces process flow time and the need for multiple sheet metal handling, thereby improving overall processing efficiency and ensuring trimming accuracy. Consequently, the final quality of the sheet metal and the accuracy of subsequent assembly are improved. The cold pressing component provides power through the hydraulic telescopic rod 31 to move the pressure seat 32, which can output stable and adjustable pressure to ensure uniform cold pressing effect on the sheet metal. This effectively prevents the pressure seat 32 from tilting or shifting during movement, ensuring the parallelism between the pressure seat 32 and the lower pressure plate. This ensures uniform force on all parts of the sheet metal and improves the quality of cold pressing.

[0019] Please see Figure 1 - Figure 4In this embodiment, two sets of lead screws 22 are provided, symmetrically distributed on the base 1. The first sprocket 23 and the second sprocket 24 are sequentially distributed on the two lead screws 22. By providing two symmetrically distributed sets of lead screws 22, and cooperating with the first sprocket 23, the second sprocket 24, and the transmission chain 25, the two lead screws 22 can rotate synchronously. This drives the sliding frames 26 on both sides and the trimming components to maintain a consistent rhythm and displacement, ensuring that the trimming force, speed, and position on both sides of the board are completely symmetrical. This effectively avoids problems such as uneven trimming of the board edges and board offset caused by inconsistent force or movement on one side, improving trimming accuracy and the overall flatness of the board. The base 1 has corresponding openings at the corresponding positions of the sliding frames 26. The sliding frame 26 slides within the sliding groove of the base 1. The matching sliding groove design on the base 1 provides a precise guide trajectory for the movement of the sliding frame 26, limiting its horizontal offset or wobbling. This ensures the sliding frame 26 can move stably and smoothly along a preset path, guaranteeing the accurate positioning of components such as the moving frame 28 and trimming blade 214 connected to the sliding frame 26 during trimming. This reduces edge trimming dimensional errors caused by displacement deviation of the sliding frame 26, improving the stability and reliability of the device. The sliding frame 26 has a matching sliding groove at a corresponding position on the moving frame 28, and the moving frame 28 slides within the sliding groove of the sliding frame 26. The matching slide groove design provides stable guidance for the sliding of the movable frame 28, enabling the movable frame 28 to precisely adjust the distance between itself and the plate along the slide groove. This ensures the straightness and stability of components such as the adjusting inner rod 29 and the trimming blade 214 on the movable frame 28 during position adjustment. A threaded rod 27 is rotatably connected inside the sliding frame 26, and the movable frame 28 is threadedly connected to the outside of the threaded rod 27. A mounting bolt 210 is installed inside the movable frame 28, located inside the adjusting inner rod 29. A mounting nut 211 is threaded onto the outside of the mounting bolt 210. A protective frame 215 is fixedly connected to the side of the fixed plate 212 near the trimming blade 214. The trimming blade 214 is located inside the protective frame 215. The sliding frame 26... The threaded rod 27 inside is threadedly connected to the movable frame 28. Rotating the threaded rod 27 allows for precise adjustment of the position of the movable frame 28, thereby flexibly adjusting the distance between the trimming blade 214 and the edge of the board to adapt to the trimming needs of boards of different widths. By passing the mounting bolt 210 through the through hole of the adjusting inner rod 29 and the movable frame 28 and tightening it with the mounting nut 211, the adjusting inner rod 29 can be firmly fixed at the set height, ensuring that the trimming blade 214 will not loosen after the height is adjusted, thus guaranteeing the stability of the trimming position. By setting a protective frame 215 on the fixed plate 212 and placing the trimming blade 214 inside it, the flying debris generated during the trimming process can be effectively blocked, protecting the safety of the operator. The movable frame 28 has a matching groove at the corresponding position of the adjusting inner rod 29.The adjusting inner rod 29 slides inside the groove of the movable frame 28. Both the adjusting inner rod 29 and the movable frame 28 have corresponding through holes at the positions of the mounting bolts 210. The mounting bolts 210 are located inside the through holes of the adjusting inner rod 29 and the movable frame 28. The movable frame 28 has four sets of through holes, distributed sequentially from top to bottom. Through the groove on the movable frame 28 that matches the adjusting inner rod 29, the adjusting inner rod 29 can slide smoothly to adjust its height. Combined with the matching through holes on both and the fixing of the mounting bolts 210 and mounting nuts 211, the adjustment inner rod 29 can be adjusted smoothly to adjust its height. The adjustable height of the trimming blade 214 is achieved through four sets of through holes distributed from top to bottom on the movable frame 28, providing multiple height settings for the adjusting rod 29. This allows for precise adaptation to different thicknesses of sheet metal, ensuring that the trimming blade 214 is always in the optimal cutting position with the edge of the sheet metal. Furthermore, after adjusting the height of the trimming blade 214, it is possible to replace it with a trimming blade of the corresponding diameter to cut sheet metal of different thicknesses. This improves the device's adaptability to different sheet metal specifications and its trimming accuracy. The multi-position design also makes height adjustment more convenient and flexible.

[0020] Please see Figure 5 In this embodiment, the cold pressing assembly includes a hydraulic telescopic rod 31 fixedly connected inside the top seat 5, a pressure seat 32 fixedly connected to the bottom of the hydraulic telescopic rod 31, a semi-circular block 33 fixedly connected to the top of the pressure seat 32, a long rod 34 rotatably connected inside the semi-circular block 33, a circular gear 35 fixedly connected to the long rod 34, and a toothed plate 36 fixedly connected to the side of the support frame 4 near the circular gear 35. The pressure seat 32 is slidably connected inside the support frame 4, and the circular gear 35 meshes with the outside of the toothed plate 36. The hydraulic telescopic rod 31 drives the pressure seat 32 to move. The hydraulic telescopic rod 31 provides power to drive the pressure seat 32 to move, which can output stable and adjustable pressure to ensure uniform cold pressing effect on the sheet material. The semi-circular block 33, long rod 34, and circular gear 35 at the top of the pressure seat 32 mesh with the toothed plate 36 on the support frame 4, and the pressure seat 32... 2. When moving up and down, the circular gear 35 rolls along the toothed plate 36, providing precise guidance and limiting for the pressure seat 32. This effectively prevents the pressure seat 32 from tilting or shifting during movement, ensuring the parallelism between the pressure seat 32 and the lower pressure plate. This ensures uniform force distribution on all parts of the sheet metal, improving the quality of cold pressing. The support frame 4 has a matching groove at the corresponding position of the pressure seat 32. The pressure seat 32 slides inside the groove of the support frame 4. The matching groove design on the support frame 4 provides rigid guidance for the up and down movement of the pressure seat 32, further limiting the lateral displacement of the pressure seat 32. This ensures that the pressure seat 32 can move smoothly and accurately along the vertical direction, avoiding swaying or tilting of the pressure seat 32 due to uneven force distribution during cold pressing. This ensures uniform pressure distribution on the sheet metal by the pressure seat 32, improving the accuracy and reliability of cold pressing.

[0021] During operation, firstly, based on the thickness of the material to be processed, slide the inner rod 29 on the movable frame 28 through the groove that matches the inner rod 29. Align the inner rod 29 with the through hole on the movable frame 28, insert the mounting bolt 210 and tighten the mounting nut 211. Use the four sets of through holes on the movable frame 28 to select the appropriate height setting to adjust the height of the trimming blade 214. If the thickness of the material varies greatly, the trimming blade 214 with the corresponding diameter can be replaced. At the same time, rotate the threaded rod 27 inside the sliding frame 26. Through the threaded connection between the movable frame 28 and the threaded rod 27, the movable frame 28 slides in the groove of the sliding frame 26 to adjust the distance between the trimming blade 214 and the edge of the material, ensuring accurate trimming position. At this time, the protective frame 215 on one side of the fixed plate 212 has surrounded the trimming blade 214, providing safety protection. Then, activate the hydraulic telescopic rod 31 to extend, causing the pressure seat 32 to move downward along the groove of the support frame 4. The semi-circular block 33 and the long rod 34 at the top of the pressure seat 32... The circular gear 35 moves with the pressure seat 32, and the circular gear 35 meshes with the toothed plate 36 on the support frame 4 to provide guidance and limit for the pressure seat 32, ensuring that the pressure seat 32 descends smoothly and makes precise contact with the plate on the base 1, outputting stable pressure to cold press and shape the plate. During the cold pressing process, the second motor 213 is started simultaneously, driving the trimming blade 214 to rotate at high speed. At the same time, the first motor 21 is started, and its output end drives a set of lead screws 22 to rotate. Through the transmission of the first sprocket 23, the second sprocket 24 and the transmission chain 25, the two sets of symmetrically distributed lead screws 22 rotate synchronously, driving the sliding frame 26 to move smoothly along the slide groove of the base 1. During the movement of the sliding frame 26, the moving frame 28, the adjusting inner rod 29 and the fixed plate 212 on it move accordingly, thereby causing the high-speed rotating trimming blade 214 to move along the edge of the plate, and synchronously trimming the two sides of the plate during cold pressing. The synchronous rotation of the two sets of lead screws 22 ensures that the trimming blades 214 on both sides move in unison, ensuring symmetrical and uniform trimming.

[0022] Through the above steps, the height of the trimming blade 214 is adjusted by cooperating with the inner rod 29, mounting bolt 210, and mounting nut 211. The distance between the threaded rod 27 on the sliding frame 26 and the base 1 is adjusted by rotating it to adapt to plates of different heights and widths, thus improving the versatility of the device. Then, the second motor 213 is started to drive the trimming blade 214 to rotate. The first motor 21 drives the lead screw 22, which in turn drives the two lead screws 22 to rotate synchronously through the transmission chain 25, the first sprocket 23, and the second sprocket 24, causing the rotating trimming blade 214 to move. This achieves synchronous trimming during cold pressing, eliminating secondary processing, reducing process time and handling, and improving efficiency, trimming accuracy, plate quality, and assembly accuracy. This solves the problem that existing cold pressing machines can only complete cold pressing of plates and cannot simultaneously trim the edges, resulting in the need to transfer the cold-pressed plates to specialized equipment for secondary trimming. This increases process flow time and may also cause deviations in the dimensions or insufficient perpendicularity of the trimmed edges due to slight displacement or deformation of the plates during transfer, affecting the final quality and subsequent assembly accuracy.
