Description

Technical Field

[0001] The utility model belongs to the field of sealing strip processing, and particularly relates to a punching device for automobile door strips. Background Art

[0002] As Figure 1 、 Figure 2 shown, the automobile door strip includes a bubble tube part 2. After the bubble tube part 2 is punched, a plurality of evenly distributed punching parts are formed. The punching parts are steps 3 with a height of only about 0.5 mm - 1 mm. Conventional punching dies usually include a fixed lower die base and a sliding upper die base. The punching tool is driven by the upper die base to slide for punching. A punching cavity for the punching tool to insert is correspondingly arranged on the lower die base to prevent the punching tool from directly colliding with the lower die base. However, due to the very thin thickness of the step 3 of the punching part, after the punching cavity is set, the support of the lower die base at the step 3 is very weak. When the punching tool punches here, it is easy to drive the bubble tube part 2 to move and deform, ultimately affecting the punching effect. Therefore, such punching is mostly manual cutting, with low efficiency. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a punching device for automobile door strips to solve the problem that the thickness of the step of the punching part is very thin, resulting in very weak support of the lower die base at the step, and when the punching tool punches here, it is easy to drive the bubble tube part to move and deform, ultimately affecting the punching effect.

[0004] According to the embodiments of the utility model, the following technical solutions are adopted:

[0005] The punching device for automobile door strips includes a frame, a support seat arranged on the frame and used for supporting the door strip, a first pressing seat slidably connected to the frame in the vertical direction, and a punching mechanism for punching the door strip. The first pressing seat is located above the support seat and used for pressing the door strip, and a plurality of support seats are arranged in parallel; the punching mechanism includes a plurality of punching parts respectively arranged between adjacent support seats. Each punching part includes two relatively arranged cutting knives, and the cutting knives are slidably arranged in the transverse direction and the sliding directions of the two cutting knives are opposite.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] In this solution, the door strip is placed on the support seat, pressed by the first pressing seat, and then punched. By arranging a plurality of support seats and punching parts between adjacent support seats, the purpose of synchronously punching multiple places on the door strip is achieved, improving the punching efficiency.

[0008] In addition, the punching part includes two groups of relatively moving cutting knives, so that the two groups of cutting knives punch against each other. Then, the two groups of cutting knives complete punching in the middle of the bubble tube part on the door strip, reducing the movement distance of a single cutting knife and the probability of deformation of the two sides of the bubble tube part due to punching influence. Moreover, the two groups of cutting knives support each other, eliminating the need for an additional punching cavity. By simply designing the relative height positions of the cutting knives and the support seats, punching requirements for different step thicknesses can be met, expanding the versatility of the equipment.

[0009] Furthermore, a second pressing seat is slidably connected to the rack vertically. The second pressing seat is located above the first pressing seat, and a telescopic member is connected between the first pressing seat and the second pressing seat, and the telescopic member expands and contracts vertically.

[0010] Furthermore, pressing plates are detachably connected to both sides of the second pressing seat. The punching part further includes a wedge seat fixed on the cutting knife, and the pressing plates and the wedge seat are in wedge surface fit.

[0011] Furthermore, a workbench is fixed on the rack, the support seat is installed on the workbench, and a telescopic column is connected between the second pressing seat and the workbench.

[0012] Furthermore, a slide plate for installing the support seat is slidably connected to the workbench, and the sliding direction of the slide plate is perpendicular to the sliding direction of the first pressing seat.

[0013] Furthermore, the support seat is detachably connected to the slide plate.

[0014] Furthermore, a mounting plate is slidably connected to the slide plate vertically, and the cutting knife is slidably connected to the mounting plate horizontally.

[0015] Furthermore, the cutting knife includes a cutting knife seat and a groove formed in the cutting knife seat. The groove is frustum-shaped and its large-mouth end is the free end. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] The following further elaborates on the present utility model in detail in conjunction with the accompanying drawings of the specification, and specific implementation manners are given.

[0026] As Figure 3 shown, an automobile door strip punching device for punching a door strip 1 as Figure 1 , Figure 2 shown, includes a frame, a support seat 7 arranged on the frame and used for supporting the door strip 1, a first pressing seat 4 slidably connected to the frame in the vertical direction, and a punching mechanism for punching the door strip 1. The first pressing seat 4 is located above the support seat 7 and used for pressing the door strip 1. In this embodiment, the support seat 7 is fixed on the frame, and a cylinder for driving the first pressing seat 4 to slide is installed on the frame. Place the door strip 1 on the support seat 7, and by sliding the first pressing seat 4 to press the door strip 1, punching can be performed.

[0027] A plurality of support seats 7 are arranged in parallel, and an installation groove 6 for placing the bubble tube part 2 of the door strip 1 is opened in the middle of the support seat 7. When the door strip 1 is placed on the support seat 7, the bubble tube part 2 of the door strip 1 is snapped into the installation groove 6. The punching mechanism includes multiple groups of punching parts respectively arranged between adjacent support seats 7 to achieve the purpose of synchronously punching multiple places on the door strip 1 and improve the punching efficiency.

[0028] The punching part includes two cutting knives 5 arranged oppositely, and the cutting knives 5 are slidably arranged in the horizontal direction and the sliding directions of the two cutting knives 5 are opposite. In this embodiment, the cutting knives 5 are slidably connected to the frame in the horizontal direction, and a cylinder for driving the cutting knives 5 to slide is installed on the frame. Combining Figure 6 , Figure 7 shown, the cutting knife 5 includes a cutting knife seat 13 and a groove 14 opened on the cutting knife seat 13. The groove 14 is frustum-shaped and the large-mouth end of the groove 14 is its free end. The free end of the cutting knife 5 is the cutting edge. Designed in this way, there is a certain supporting effect on the cutting edge, and the service life of the cutting knife 5 is improved.

[0029] During specific use, the door strip 1 is placed on the support base 7, the bubble tube portion 2 of the door strip 1 is snapped into the installation groove 6 on the support base 7, the first pressure seat 4 is slid to press the door strip 1, and at the same time, the cutting knives 5 of multiple punching members are driven to move synchronously. The two cutting knives 5 of the punching member are opposed to each other, and the two cutting knives 5 complete punching in the middle of the bubble tube portion 2 of the door strip 1, and multiple punching members synchronously complete multiple punches on the door strip 1.

[0030] In another embodiment of the present invention, the sliding of the cutting knife 5 is not driven by a cylinder. Specifically, in combination with Figure 4 、 Figure 5 As shown, in this embodiment, a second pressure seat 8 is slidably connected to the frame in the vertical direction. The second pressure seat 8 is located above the first pressure seat 4. An expansion member 12 is connected between the first pressure seat 4 and the second pressure seat 8. The expansion member 12 expands and contracts in the vertical direction. Specifically, the expansion member 12 can be a conventional telescopic rod or a telescopic spring in the prior art. A cylinder for driving the second pressure seat 8 to slide in the vertical direction is installed on the frame.

[0031] Pressure plates 9 are detachably connected to both sides of the second pressure seat 8. Specifically, the pressure plates 9 are bolted to the second pressure seat 8, which is convenient for replacing the pressure plates 9 according to requirements. The punching member further includes a wedge seat 10 fixed on the cutting knife 5. The pressure plate 9 and the wedge seat 10 are in wedge surface fit. Then, during the process of the pressure plate 9 sliding down with the second pressure seat 8, the wedge surface of the pressure plate 9 pushes the wedge surface of the wedge seat 10, and further pushes the wedge seat 10 to slide horizontally, so as to drive the cutting knife 5.

[0032] In this embodiment, the driving of the cutting knife 5 is synchronously realized by the downward sliding of the second pressure seat 8. The first pressure seat 4 is arranged below the second pressure seat 8. After the first pressure seat 4 presses the door strip 1, the second pressure seat 8 continues to slide down, and the expansion member 12 contracts. At this time, the pressure plate 9 pushes the wedge seat 10 to slide. Then, by setting the distance between the first pressure seat 4 and the second pressure seat 8 and setting the wedge surface angle of the pressure plate 9 and the wedge seat 10, it can be ensured that the wedge seat 10 slides after the first pressure seat 4 presses the door strip 1 tightly, so as to realize punching, and there is no need to additionally monitor whether the door strip 1 has been pressed tightly before punching.

[0033] In another embodiment of the present invention, in combination with Figure 8As shown in the figure, in order to make the downward sliding of the second pressure seat 8 more stable, a workbench 16 is fixed on the frame. The support seat 7 is installed on the workbench 16. A telescopic column 15 is connected between the second pressure seat 8 and the workbench 16. Specifically, the telescopic column 15 can be an electric telescopic rod in the prior art, or other telescopic rods with telescopic functions. In the actual design process, multiple telescopic columns 15 can be arranged circumferentially along the second pressure seat 8. During the downward sliding of the second pressure seat 8, it is always restricted by the telescopic column 15, making the downward sliding more stable. In addition, by setting the telescopic range of the telescopic column 15, for example, restricting the minimum retractable limit of the electric telescopic rod, the maximum distance that the second pressure seat 8 can slide downward can be restricted, so as to avoid over-pressing the door strip 1 beyond the limit and damaging the door strip 1 due to the excessive downward sliding distance of the second pressure seat 8, or avoiding excessive pushing force on the wedge seat 10 due to the excessive downward sliding distance of the second pressure seat 8, which may further cause damage to the two relatively arranged cutting knives 5.

[0034] In another embodiment of the present invention, in combination with Figure 4 , Figure 5 , Figure 8 As shown in the figure, in order to facilitate placing the door strip 1 on the support seat 7, a slide plate 11 for installing the support seat 7 is slidably connected to the workbench 16. The sliding direction of the slide plate 11 is perpendicular to the sliding direction of the first pressure seat 4. A cylinder for driving the slide plate 11 to slide is installed on the workbench 16. By sliding the slide plate 11, the support seat 7 can be driven away from the lower part of the first pressure seat 4, avoiding the interference of the first pressure seat 4 on placing the door strip 1.

[0035] In another embodiment of the present invention, in order to facilitate replacing the support seat 7 according to the shape and size of the door strip 1 or adjusting the distance between adjacent support seats 7, in this embodiment, the support seat 7 is detachably connected to the slide plate 11. Specifically, the support seat 7 is bolted to the slide plate 11, facilitating the installation and disassembly of the support seat 7.

[0036] In another embodiment of the present invention, in order to facilitate adjusting the relative height between the cutting knife 5 and the support seat 7, and thus controlling the thickness of the step 3 on the door strip 1 after punching, an installation plate is slidably connected vertically on the slide plate 11. A cylinder for driving the installation plate to slide vertically is installed on the slide plate 11. The cutting knife 5 is slidably connected horizontally on the installation plate. A cylinder for driving the cutting knife 5 to slide horizontally is installed on the installation plate. By adjusting the position of the installation plate, the height of the top of the cutting knife 5 can be controlled, and thus the height difference between the top of the cutting knife 5 and the upper end of the support seat 7 can be controlled.
