Description

Technical Field

[0001] This utility model relates to the field of profile processing technology, and in particular to a profile notch mold. Background Technology

[0002] In the field of architectural decoration, C-profiles and L-profiles, with their high strength and ease of processing, are widely used in constructing supporting structures or splicing components. During actual assembly, it is often necessary to splice two adjacent profiles in an intersecting manner. In this case, the ends or sides of the two profiles are prone to structural overlap, creating positional interference and preventing a tight fit. Therefore, it is necessary to notch the interfering area of ​​either profile, removing material from a specific area to allow the two profiles to form a complementary fit when spliced, thus meeting assembly requirements.

[0003] Currently, the common cutting process uses a tabletop circular saw. First, the rectangular dimensions of the notch (such as length and width) are determined based on the splicing requirements, and the notch outline is marked on the profile surface. Then, the operator places the profile on the tabletop circular saw, using the marked lines as a reference, and starts the machine to complete the notch cutting. The entire process requires manual completion of each step, including marking, positioning, and cutting, making batch continuous processing impossible and resulting in low work efficiency. Furthermore, after cutting with the tabletop circular saw, the edges of the notch are prone to burrs and chipping, requiring additional manpower for polishing, further extending the overall processing cycle.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0017] This utility model provides a profile notch mold. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0019] Please see Figures 1 to 7 As shown, this utility model provides a profile notch die, adapted for use on a stamping press, specifically a C-type stamping press (also known as a C-type pressure press). The notch die is installed inside the stamping press, and during operation, the stamping press drives the notch die to complete the opening and closing actions, thereby stamping a notch on the profile to be processed to form a notch that meets the splicing requirements. The C-profile a before and after processing are shown below. Figure 9 As shown, the end of the C-profile a after notching treatment has a notch a1.

[0020] The notch-opening die includes: an upper die base 1, a lower die base 3, and several guide pillars 5; the upper die base 1 is used to fix itself on the punch of the stamping machine, and the bottom of the upper die base 1 is provided with an L-shaped cutter 2; the lower die base 3 includes a base 31, a raised platform 32, and a support base 33; the base 31 is used to fix itself on the worktable of the stamping machine, the raised platform 32 is provided on the base 31, and the support base 33 is provided on the raised platform 32; the support base 33 is provided with a right-angled portion 331, and the right-angled portion 331 is connected to the cutter. 2. A rectangular notch is cut into the profile; the support base 33 is provided with a first groove 332 extending along the X-axis and a second groove 333 extending along the Y-axis. The first groove 332 and the second groove 333 are respectively provided with adjustable positioning blocks 4. The two positioning blocks 4 are used to abut against the adjacent two sides of the profile to position the profile; the upper ends of several guide columns 5 are fixed on the upper mold base 1, and their lower ends are slidably connected to the support base 33 and extend downward into the raised platform 32.

[0021] During the notch-making process, first, according to the required notch size of the profile to be processed, adjust the positions of the two positioning blocks 4 along the first and second slide grooves 332 and 333 of the support base 33 respectively, so that the distance between the two positioning blocks 4 and the edge of the right angle portion 331 exactly matches the notch size; then place the profile on the support base 33, so that the adjacent two sides of the profile abut against the two positioning blocks 4 respectively, completing the positioning of the profile. Next, start the stamping machine. The punch of the stamping machine drives the upper die base 1 to move downward. At this time, the guide post 5 slides downward along the support base 33, which plays a guiding and limiting role; as the upper die base 1 continues to descend, when the L-shaped cutter 2 at its bottom engages with the right angle portion 331, the notch-making action can be quickly completed on the profile. After the stamping is completed, the stamping machine drives the punch to move the upper die base 1 to reset upward. The guide post 5 rises synchronously with the upper die base 1. The operator only needs to remove the processed profile from the support base 33 to enter the processing flow of the next profile.

[0022] By adjusting the position of the positioning block 4 along the first slide groove 332 and the second slide groove 333, rectangular notches of different sizes can be processed on the profile, adapting to the processing needs of various specifications of C-shaped and L-shaped profiles, with wide applicability; at the same time, under the limiting of the positioning block 4 and the stable guidance of the guide post 5, it can be ensured that the size of the notch is consistent each time it is processed, effectively avoiding size deviation; and continuous batch processing can be achieved, greatly improving work efficiency; in addition, the edges of the stamped notch are flat and smooth, requiring no additional grinding, further simplifying the processing process and reducing labor and time costs.

[0023] It should be noted that, as Figure 8 As shown, the stamping machine b is existing technology. The punch b1 and worktable b2 of this stamping machine b are each provided with several spaced T-slots. The upper die holder 1 is fixed to the bottom of the slide block by T-nuts and screws, and the base 31 of the lower die holder 3 is also fixed to the worktable by T-nuts and screws. The above-mentioned method of fixing the die to the stamping machine b is a commonly used technique in this field, and its specific structure and working principle will not be elaborated here.

[0024] In a preferred embodiment, see [reference] Figure 3 , 45. It also includes two adjusting components 6, which are respectively disposed on the first slide groove 332 and the second slide groove 333. The first slide groove 332 and the second slide groove 333 each include a vertical groove 334 and a horizontal groove 335, which are spliced ​​together to form an inverted T-shaped structure. The positioning block 4 is slidably connected to the vertical groove 334. The adjusting component 6 includes a rectangular locking block 61 and a locking screw 62. The rectangular locking block 61 is slidably connected to the horizontal groove 335, and the locking screw 62 is used to fix the positioning block 4 and the rectangular locking block 61. During adjustment, first loosen the locking screw 62, then push the positioning block 4 to move along the length direction of the vertical groove 334, while the rectangular locking block 61 moves with the positioning block 4 until the positioning block 4 moves to a preset position that matches the size of the notch; finally, tighten the locking screw 62 to lock the positioning block 4 and the rectangular locking block 61 on the first slide groove 332 or the second slide groove 333. The above settings facilitate the adjustment of the positions of the two positioning blocks 4, and the positioning blocks 4 are installed stably, which can ensure the consistency of the notch size when processing different batches of profiles.

[0025] In a preferred embodiment, see [reference] Figure 5 The positioning block 4 includes a fixed block 41 and a movable block 42. The fixed block 41 is mounted on the adjusting assembly 6. Specifically, the bottom of the fixed block 41 is provided with a T-shaped slider 412 that slides in connection with the vertical groove 334. The locking screw 62 passes through the rectangular locking block 61 and the T-shaped slider 412 in sequence and is threaded into the fixed block 41. By screwing in the locking screw 62, the T-shaped slider 412 and the rectangular locking block 61 are pressed against the first groove 332 or the second groove 333 to lock the position of the fixed block 41 and ensure that the fixed block 41 will not shift during the stamping process. The movable block 42 is detachably connected to the fixed block 41 and can be flexibly replaced according to the actual size of the notch to be processed. Figure 7 As shown, when the required notch size (width and length) is large, a larger movable block 42 can be used. By increasing the contact area between the side of the movable block 42 and the side of the profile, the profile can be placed stably. Figure 6 As shown, when the size of the notch to be processed is small, the movable block 42 with a narrower width can be replaced. By reducing the width of the movable block 42, the positional interference problem caused by the spatial overlap of the two movable blocks 42 near the right angle 331 of the support 33 can be avoided, ensuring that the movable block 42 can properly abut against the adjacent two sides of the profile and achieve precise positioning.

[0026] In this embodiment, the length of the movable block 42 is 30-50mm. When notching the C-profile, the right-angle portion 331 of the support 33 needs to be adapted to the structural characteristics of the C-profile and placed within the internal space of the C-profile. For C-profiles with smaller internal spaces, the thickness of the support 33 needs to be designed to be relatively small to ensure that the right-angle portion 331 can be smoothly embedded into the C-profile. Therefore, the ends of the first groove 332 and the second groove 333 on the support 33 cannot extend to the edge of the right-angle portion 331. If the groove is too close to the right-angle portion 331, it will further weaken the structural strength of the support 33, which may lead to deformation or damage of the right-angle portion 331 during the stamping process. Preferably, the length of the movable block 42 is set to 50mm. Under the premise that the strength of the support 33 is not affected by the groove design, the extended movable block 42 can compensate for the distance that the groove does not extend to the right-angle portion 331, so that the movable block 42 can still stably abut against the side of the C-profile, thereby realizing the processing of smaller notches.

[0027] Further, see Figure 5 The fixed block 41 has a hook 411 with a figure-7 structure at its end, and the movable block 42 has a hook groove 421 that matches the hook 411 at its end. The hook 411 and the hook groove 421 are slidably connected in the horizontal direction. The horizontal direction is perpendicular to the direction of the first slide groove 332 or the second slide groove 333 to which it is connected. The operator pushes or pulls the movable block 42 in the horizontal direction so that the hook 411 can slide smoothly in or out along the hook groove 421, thereby realizing the quick assembly and disassembly of the movable block 42. In addition, when adjusting the overall position of the positioning block 4, with the cooperation of the hook 411 and the hook groove 421, the movable block 42 can move along the slide groove with the fixed block 41, and the two will not be relatively offset or separated during the movement.

[0028] In a preferred embodiment, see [reference] Figure 1 On the vertical projection plane, both the first slide groove 332 and the second slide groove 333 are located outside the raised platform 32; the height of the raised platform 32 is 50-100mm. By setting the raised platform 32, the vertical distance between the bottom of the support base 33 and the base 31 is increased, forming sufficient accommodating space, suitable for processing wider profiles, and avoiding interference between the other side of the profile placed on the support base 33 and the surface of the base 31. The raised height of 50-100mm can accommodate the bottom space requirements of most wide profiles, ensuring that the profile does not collide with the base 31 when placed.

[0029] Preferably, the horizontal groove 335 of the first slide groove 332 and the second slide groove 333 extends to the bottom of the support base 33, and the rectangular locking block 61 is installed in the horizontal groove 335 from bottom to top to facilitate the installation and removal of the adjustment component 6; the shank of the locking screw 62 passes through the preset through hole on the rectangular locking block 61 from bottom to top and is screwed to the positioning block 4; wherein, the locking screw 62 is a hand-tightening screw, its head is provided with anti-slip texture, and the diameter of the head is larger than the diameter of the through hole on the rectangular locking block 61, so that the operator can directly hold the screw head with his hand to tighten it.

[0030] In a preferred embodiment, see [reference] Figure 2 The upper end of the guide post 5 is provided with a limiting block 51, the height of which is greater than the distance between the upper surface of the support base 33 and the top of the positioning block 4. When the press drives the upper die base 1 to move the guide post 5 vertically downward (i.e., the die is closed for notch processing), the limiting block 51 descends synchronously with the guide post 5. If the press punch over-strokes during processing (e.g., the punch's descent stroke exceeds the preset cutting stroke), the bottom surface of the limiting block 51 will preferentially contact the top surface of the support base 33 and form a rigid abutment. Through the above settings, the upper die base 1 is restricted from continuing to move downward, thereby effectively preventing the upper die base 1 and the lower die base 3 from colliding due to excessive proximity and avoiding damage to the die structure.

[0031] In a preferred embodiment, see [reference] Figure 3 Each of the first slide groove 332 and the second slide groove 333 is provided with a scale 7 on its side. The length direction of the scale 7 is consistent with the extension direction of the corresponding slide groove. The scale 7 is marked with graduations accurate to the millimeter level. The starting point of the graduation is aligned with the edge of the right angle portion 331 on the support base 33, forming a visual positioning reference, which can greatly reduce the time cost of positioning adjustment.

[0032] In a preferred embodiment, see [reference] Figure 2 , 3 Two cutters 2 are symmetrically arranged at the bottom of the upper die base 1. Two right-angled portions 331 correspond to the positions of the two cutters 2, and each right-angled portion 331 has a first groove 332 and a second groove 333 on its side. Each groove is equipped with an adjustable positioning block 4 and an adjustment component 6, forming two independent and structurally identical notch processing stations. In actual operation, for a single profile that needs to be processed with double notches, after the profile is positioned by the independent positioning block 4 at each station, the stamping machine can be started to complete the processing of the two notches in sequence, efficiently meeting the double notch processing requirements of a single profile.

[0033] Preferably, the first grooves 332 on the two right-angle portions 331 can be shared. The shared first groove 332 extends along the symmetrical center line of the two right-angle portions 331, and its length covers the adjustment requirements of the two processing stations. It is not necessary to open an independent first groove 332 for each right-angle portion 331, so as to avoid the problem of weakening the local strength of the support seat 33 due to the opening of multiple grooves, thereby ensuring the structural stability of the support seat 33 during the stamping process.
