Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing molds, specifically to a quick adjustment device for roll width positioning of blanking molds. Background Technology

[0002] Currently, in stamping and blanking dies, the commonly used roll width positioning method involves an integral guide block mounted on the lower die base or lower die support plate. After the sheet metal enters, the fitter manually adjusts the position of the guide block according to the sheet metal. This method is simple in design, but in actual use, the adjustment amount relies entirely on the fitter's feel, which is not precise enough. Furthermore, each adjustment requires removing or loosening the guide block fixing screws to move it back and forth, which is inconvenient and increases the die's debugging time on the press, leading to higher debugging costs. This utility model provides a quick roll width positioning adjustment device to overcome the bottleneck of existing technology. It eliminates the steps of removing or loosening screws, effectively improving the efficiency of roll width adjustment and positioning, reducing the number of steps for on-site fitter operations, and significantly improving positioning accuracy.

[0003] Chinese utility model application CN201520059934.2 provides a positioning device and a blanking die. In this utility model, after the sheet metal enters the machine, a fitter manually adjusts the adjusting limit screws according to the sheet metal to change the movement range of the positioning component. This method is simple in design but not precise enough, and each adjustment requires re-tuning, which is time-consuming and does not solve the aforementioned technical defects.

[0004] Chinese utility model application CN202020741422.5 discloses an adjustable positioning structure for a blanking die. This utility model adds multiple positioning pins to the traditional strip positioning mechanism for precise positioning, solving problems such as loosening of the blanking die after long-term processing and unstable feeding. However, the adjustment process still requires manual positioning and calibration multiple times and bolt disassembly, which is time-consuming and labor-intensive, and does not solve the aforementioned technical defects.

[0005] Chinese utility model application CN202122198728.8 discloses an adjustable positioning mechanism for a blanking die. Compared with the prior art, this utility model has a simple adjustment method, is suitable for mass production, and does not require disassembling the nut. However, the adjustment and positioning accuracy is low, the structure is complex, and the compatibility with different models of equipment is low. In summary, it does not solve the defects of the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a quick adjustment device for roll width positioning of blanking dies. This device addresses the problem that in traditional stamping and blanking dies, the roll width positioning requires frequent manual adjustment of the guide block position due to different sheet metal specifications. This adjustment requires repeated disassembly of bolts, which is labor-intensive and time-consuming, affecting normal production progress. Furthermore, the adjustment accuracy requires high technical skills, necessitating technicians to achieve the appropriate precision. Production failures also lead to a high dependence on technicians, which can easily delay the project schedule and disrupt normal production.

[0007] To address this, a quick adjustment device for roll width positioning of a blanking die is proposed, comprising a bottom limiting pad, a pair of flat-head screws on both sides of the bottom limiting pad surface, a guide plate above the bottom limiting pad, the guide plate being located between the flat-head screws on both sides, a first through hole in the middle of the guide plate, and an adjustment knob inside the first through hole; a fixing seat above the guide plate, a second through hole in the middle of the fixing seat, the second through hole and the first through hole being positioned correspondingly; a threaded hole is also provided on the surface of the fixing seat at a position corresponding to the flat-head screw below, a positioning hole is provided on the side of the fixing seat, the positioning hole extending into the second through hole, the positioning hole being used to fix and install a positioning spring pin, the lower part of the adjustment knob passing through the first through hole and the second through hole and fixed inside the guide plate, while the fixing seat, through the threaded hole and the flat-head screws, restricts the guide plate to the surface of the bottom limiting pad, and finally the two parts cooperate to form a whole.

[0008] The advantages are as follows: This utility model assembles the bottom limiting washer, guide plate, adjusting knob, and fixing base together using flat-head screws. A removable positioning spring pin is provided on the side of the fixing base. During operation, turning the adjusting knob controls the movement of the guide plate on the bottom limiting washer, allowing for quick adjustment of the roll width positioning. After adjustment, the positioning spring pin is inserted for fixation. The entire process eliminates the need for frequent bolt disassembly, making adjustment more convenient. The first through hole on the guide plate and the second through hole on the fixing base are for placing the adjusting knob, facilitating its rotation. The fixing base has threaded holes that mate with the flat-head screws, allowing the fixing base to securely mount the guide plate onto the bottom limiting washer.

[0009] A further improvement is that the structure of the adjustment knob is two eccentric cylinders combined together, including a hand-held part, a first eccentric cylinder is provided below the hand-held part, and a second eccentric cylinder is provided below the first eccentric cylinder, wherein the diameter of the second eccentric cylinder is smaller than the diameter of the first eccentric cylinder, and the two are not concentric axes.

[0010] The effect is that two eccentric cylinders of different sizes and not concentric axes, when the adjustment knob is turned, will not spin in place. The second eccentric cylinder at the bottom will form a large arc trajectory when it rotates. In this way, the movement of the guide plate can be indirectly controlled, thereby adjusting the roll width positioning.

[0011] A further improvement is that a number of evenly spaced circular grooves are provided on the side surface of the first eccentric cylinder.

[0012] The effect is that when the positioning adjustment is completed, the positioning spring pin passes through the positioning hole and abuts against the circular groove, which fixes the adjusted guide plate below. At the same time, the setting of multiple evenly distributed circular grooves makes it easier for users to control the accuracy of the roll width positioning adjustment.

[0013] A further improvement is that when the fixing seat restricts the guide plate to the surface of the bottom limiting pad, a receiving space is formed under the fixing seat to accommodate and restrict the guide plate. In order to observe the movement of the guide plate in the receiving space, the structure of the receiving space is an open shape with one side not closed.

[0014] The effect is that the guide plate needs to move on the bottom limiting pad to adjust the roll width positioning. The fixed seat is set with a space to accommodate and limit the guide plate, which not only does not forcibly fix the guide plate, but also protects and limits it.

[0015] A further improvement is that the second through hole on the surface of the fixing seat is engraved with scale markings corresponding to the number of circular grooves.

[0016] The effect is that the scale markings, combined with the aforementioned circular grooves, make it easier and more intuitive for users to adjust the appropriate roll width accuracy during adjustment.

[0017] A further improvement is that the second through hole on the surface of the fixing seat is circular and adapted to the first eccentric cylinder.

[0018] The effect is that the compatible settings facilitate smooth rotation of the adjustment knob within the mounting base.

[0019] A further improvement is that when the positioning pin passes through the positioning hole on the side of the fixed seat, the positioning pin will abut against the circular groove on the side of the first eccentric cylinder, which is used to fix the guide plate after adjustment and positioning.

[0020] The effect is that this setting secures the adjusted guide plate.

[0021] A further improvement is that the first through hole structure on the surface of the guide plate is rectangular and adapted to the second eccentric cylinder.

[0022] The effect is that this setting makes it easier to adjust the knob to control the movement of the guide plate on the bottom limit pad.

[0023] A further improvement is that a pair of fixing screws are provided on both sides of the bottom limiting pad.

[0024] The advantage is that the fixing screws allow this invention to be installed on the lower die base or lower die support plate of the stamping and blanking die, and the fixing screws are easier to remove.

[0025] A further improvement is that: above the fixing screw and at a position corresponding to the fixing seat, the fixing seat at this position has a notch on each side to facilitate the installation of the fixing screw.

[0026] The effect is that the notch design makes it easier to install the fixing screws on the lower die base or lower die support plate of the stamping and blanking dies, and the notch design further improves the ease of disassembly of the fixing screws. Beneficial effects

[0027] This invention provides a quick adjustment device for roll width positioning in blanking dies. The roll width positioning can be quickly adjusted by controlling the movement of the guide plate using an adjustment knob. After adjustment, a positioning spring pin is inserted for fixation. The entire process eliminates the need for frequent bolt disassembly, making adjustment more convenient. Furthermore, the scale markings on the surface of the fixing base provide users with adjustment parameters. Users can achieve high-precision and faster roll width positioning adjustment by using the appropriate parameters recorded from multiple adjustments. This invention features a simple structure, eliminates the need for repeated screw disassembly during operation, and offers advantages such as fast positioning adjustment speed and high adjustment accuracy.
