Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, specifically to a punching production line that facilitates mold replacement. Background Technology

[0002] In the automotive machinery manufacturing industry, automated punching production lines are an important component of modern manufacturing, primarily used to improve production efficiency and reduce labor costs. Punching processes are extensively used in the production of various sheet metal and automotive parts. For example, bumpers, energy-absorbing boxes, and base plates typically require multiple punching operations. Products with high production volumes and multiple punching operations are often planned for automated punching lines. To accommodate different products, the single-sequence dies on the automated punching line can be switched. However, the existing punching line gantry transfer device is located directly above the die working area, interfering with the die hoisting space. Furthermore, several robotic arms on the punching transfer gantry cannot be moved to make way, resulting in very cumbersome die changes. Current die-changing methods typically involve lifting the die with a die lifter, transferring it from the automated punching production line (line body) to a die-shifting device, and finally using an overhead crane or forklift to hoist and move the die. External docking die-shifting devices are mainly used to ensure that the die does not interfere with the gantry during transfer and hoisting.

[0003] Therefore, the drawbacks of the existing mold-changing method are as follows: First, this method requires the design and installation of a mold lifter in the mold area of ​​the production line to lift and slide the mold. The design and installation of the lifter itself not only increases costs but also leads to a more complex and robust die holder structure, further increasing the cost of the die holder. Second, the external mold-moving device also incurs significant costs and occupies space in the production workshop. Increased workshop area contributes to higher production costs and lower product profits. Third, this mold-changing method involves numerous steps: lifting the mold, transferring it to the mold-moving device, hoisting it, and then reversing the process to transfer the new mold to the mold working area. The transfer of a large number of molds on the production line requires manual intervention, wasting considerable time and manpower. In view of these problems, it is necessary to design and manufacture a punching production line that facilitates mold changing. This can be achieved by changing the structural layout of the production line and the mold-changing method to solve the problems of high mold-changing costs, large footprint, and cumbersome procedures in the existing automated production lines. Utility Model Content

[0004] This invention aims to overcome the deficiencies of existing technologies and provide a punching production line that facilitates mold replacement, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A punching production line for easy die replacement includes a support frame, a transfer gantry, and a punching die frame. The support frame is disposed on one side of the punching die frame and has a first moving component. The first moving component includes a first guide rail and a first slide block. The head of the first guide rail extends above the punching die frame, and the first slide block matches the first guide rail and can slide on the first guide rail. There are 2-3 supports, and the first guide rails on all supports are arranged in parallel. The transfer gantry is movably fixed to the first slide block and has a second guide rail and a second slide block that can move along the second guide rail. The second slide block has a material gripping component. The punching die frame has a punching die area for mounting punching dies.

[0006] The aforementioned punching production line, which facilitates mold replacement, has a horizontal adjustment component and a height adjustment component mounted on the first slide. The horizontal adjustment component includes a horizontal base plate, an adjustment sleeve, and an adjustment screw. The horizontal base plate is horizontally mounted on the slide and has a first screw hole. The adjustment sleeve has an external thread that matches the first screw hole, and a second screw hole that matches the adjustment screw. The upper end of the adjustment screw is supported at the bottom of the transfer gantry. By rotating the adjustment sleeve, the adjustment screw can be moved up and down to adjust the height of the support point of the transfer gantry. The adjustment sleeve has an adjustment sleeve locking nut that matches its external thread, and the adjustment screw has an adjustment screw locking nut that matches its external thread. The height adjustment component adopts the same structure as the horizontal adjustment component, that is, the same structure as the horizontal adjustment component rotated 90 degrees.

[0007] The aforementioned punching production line, which facilitates mold replacement, has a laser rangefinder sensor installed on the slide and a laser reflector installed at one end of the bracket.

[0008] The aforementioned punching production line, which facilitates mold replacement, also has a first rack on the support and a first gear on the slide that matches the first rack. The first gear is driven by a first motor. The aforementioned punching production line, which facilitates mold replacement, includes a material gripping assembly comprising a guide seat and a guide rod that can slide up and down along the guide seat. The guide seat is provided with a guide hole, and the guide rod matches the guide hole, forming a sliding pair. A drive cylinder is connected between the guide seat and the guide rod, and a material gripping robot is provided below the guide rod.

[0009] The aforementioned punching production line, which facilitates mold replacement, has a positioning component on the first slide. The positioning component includes a pin-through cylinder, which is vertically arranged with a positioning pin below it. A positioning hole is provided on the bracket. The pin-through cylinder pushes the positioning pin downward to pass through the positioning hole, thereby positioning the first slide.

[0010] The aforementioned punching production line, which facilitates mold replacement, has a limit plate 1 and a limit plate 2 respectively installed at both ends of the first guide rail to prevent the first slide from falling off the first guide rail. Beneficial effects

[0011] Compared with the prior art, this utility model has the following advantages: This method employs a system where a first slide is mounted on multiple supports, and a transfer gantry is installed on each first slide. The supports are positioned on one side of the punching die frame. During punching operations, the transfer gantry moves with the first slide to above the punching die area. When changing the punching die, the transfer gantry moves with the first slide away from the punching die area, freeing up space for die hoisting operations and enabling in-situ die replacement. Compared to traditional die replacement methods, this method eliminates the need for die lifters and die moving devices, reducing equipment purchase and installation costs, significantly simplifying the replacement process, requiring less workshop space, and offering high safety and reliability.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1-5 As shown, this utility model includes a support frame 1, a material transfer truss 2, and a punching die frame 3; The bracket 1 is set on one side of the punching die frame 3. The bracket 1 is equipped with a first moving component, which includes a first guide rail 1-1 and a first slide block 1-2. The head of the first guide rail 1-1 extends above the punching die frame 3. The first slide block 1-2 matches the first guide rail 1-1 and can slide on the first guide rail 1-1. The number of brackets 1 is 2-3 or more. The specific number is determined by the truss length and weight. The material transfer truss 2 ranges from several meters to more than ten meters. The brackets can be set at intervals of 2-3 meters. The bracket 1 can be in the shape of a gate. The first guide rails 1-1 on all brackets 1 are set in parallel.

[0016] The transfer gantry 2 is movably fixed on the first slide block 1-2. The first slide block 1-2 slides along the first guide rail, which can drive the transfer gantry 2 to move. The transfer gantry 2 is provided with a second guide rail 2-1 and a second slide block 2-2 that can move along the second guide rail 2-1. The second slide block 2-2 is provided with a material gripping assembly. The punching die frame 3 is provided with a punching die area 3-1 for mounting punching dies.

[0017] The bracket 1 is set on one side of the punching die frame 3. When it is necessary to replace the punching die, the truss 2 slides along the first guide rail 1-1 away from the punching die area 3-1, which facilitates the hoisting operation when replacing the punching die.

[0018] Because the material transfer truss 2 is quite long, and multiple first slides 1-2 support it, the following design can be adopted to ensure the straightness of the truss 2: The first slides 1-2 are equipped with horizontal adjustment components and height adjustment components, such as... Figure 5 As shown. The horizontal adjustment assembly includes a horizontal base plate 4, an adjustment sleeve 4-1, and an adjustment screw 4-2; the horizontal base plate 4 is horizontally disposed on the slide block 1-2, and has a first screw hole thereon; the adjustment sleeve 4-1 has an external thread that matches the first screw hole, and the adjustment sleeve 4-1 also has a second screw hole that matches the adjustment screw 4-2; the upper end of the adjustment screw 4-2 is supported on the bottom of the material transfer truss 2.

[0019] By turning the adjusting sleeve 4-1, the adjusting screw 4-2 can be moved up and down, thereby adjusting the height of the support point of the material transfer truss 2. The adjusting sleeve 4-1 is equipped with an adjusting sleeve locking nut 4-1-1 that matches its external thread, and the adjusting screw 4-2 is equipped with an adjusting screw locking nut 4-2-1 that matches its external thread. The height adjustment component can adopt the same structure as the horizontal adjustment component, that is, the same structure as the horizontal adjustment component rotated 90 degrees.

[0020] The head of the adjusting screw 4-2, that is, the end that contacts the material transfer truss 2, can be provided with a threadless area. The outer diameter of the threadless area is smaller than the outer diameter of the threaded area of ​​the adjusting screw 4-2, so as to ensure that the threadless area can pass smoothly through the second screw hole on the adjusting sleeve 4-1. The length of the threadless area can be 3-5mm. The purpose of setting the threadless area is to prevent the adjusting screw 4-2 from being difficult to unscrew from the adjusting sleeve 4-1 after the head thread is damaged.

[0021] To ensure synchronization when the truss exits the punching die area during die replacement, the following design can be adopted: a laser rangefinder 5 is installed on slide 1-2, and a laser reflector 5-1 is installed at one end of the bracket 1. The laser rangefinder or laser range meter can be a Steinbang SGF-10NM-485, with a range of up to 10 meters; other brands or models can also be used for different operating distances. Since the length of the truss 2 varies from several meters to over ten meters, to prevent deformation due to different operating speeds of the first slides 1-2 during movement, the operating status of the first slides 1-2 can be monitored by comparing the distances measured by the laser rangefinders 5 on multiple first slides 1-2. The data measured by the laser rangefinder can be observed manually, and then the movement or stop of a certain first slide 1-2 can be controlled to ensure the straightness of the truss during the movement. Of course, the data of multiple laser rangefinders 5 can also be output to the control circuit, and the PLC controller or CPU can control the start and stop of the drive motor of the first slide 1-2 according to the length data of each laser rangefinder 5, thereby controlling the movement or stop of the first slide 1-2.

[0022] The first slide block 1-2 can be driven by the following design: a first rack 1-3 is also provided on the bracket 1, and a first gear matching the first rack 1-3 is provided on the slide block 1-2. The first gear is driven by the first motor 1-4.

[0023] The material gripping assembly can be designed as follows: The assembly includes a guide seat 2-2-1 and a guide rod 2-2-2 that can slide up and down along the guide seat 2-2-1. The guide seat 2-2-1 has a guide hole, and the guide rod 2-2-2 matches the guide hole, forming a sliding pair. A material gripping robot 2-2-3 is located below the guide rod 2-2-2. The movement of the guide rod 2-2-2 along the guide seat 2-2-1 can be driven by a cylinder, with a cylinder connecting the guide seat 2-2-1 and the guide rod 2-2-2. The number of second sliding seats 2-2 is three or more, depending on the requirements of the material gripping and punching process.

[0024] During the punching operation, the positioning of the first slide block 1-2 on the first guide rail 1-1 can be designed as follows: a positioning component is provided on the first slide block 1-2, the positioning component including a pin-piercing cylinder 6, the pin-piercing cylinder 6 is vertically arranged, a positioning pin is provided below it, and a positioning hole is provided on the bracket 1. The pin-piercing cylinder 6 pushes the positioning pin downward to pass through the positioning hole, thereby positioning the first slide block 1-2. Two positioning holes can be provided on the bracket 1, one located at the position where the first slide block 1-2 is when the transfer gantry 2 is working normally; and one located at the position where the punching die needs to be changed, and the transfer gantry 2 slides back with the first slide block 1-2 to the other end of the bracket 1.

[0025] To prevent the first slide block 1-2 from detaching from the first guide rail 1-1, limit plates 7-1 and 7-2 are respectively provided at both ends of the first guide rail 1-1 to prevent the first slide block 1-2 from falling off the first guide rail 1-1.
