[0035] The following is for reference. Figures 1 to 6 The punching device of this application is described in detail.
[0036] refer to Figure 1 , Figure 2 and Figure 5 The punching device according to an embodiment of the present invention includes an upper punching die 10, a lower punching die 20, and a driving assembly (not shown in the figure).
[0037] The upper punching die 10 includes an upper die base 100 and a punching structure 200. The punching structure 200 is disposed on the upper die base 100 and is used to punch holes in a predetermined area of the tube wall of the tubular component. The lower punching die 20 includes a lower die base 300 and a support assembly 400. The lower die base 300 is provided with a bearing groove 310 extending along a predetermined horizontal direction. The bearing groove 310 is used to support the tubular component. The support assembly 400 is disposed on the lower die base 300 and includes a driving structure 410 and a clamping structure 420. The clamping structure 420 is disposed on one side of the bearing groove 310 in the predetermined horizontal direction and is used to clamp a predetermined area of the tubular component on the bearing groove 310. The driving structure 410 is connected to the clamping structure 420 and is used to drive the clamping structure 420 to move along the predetermined horizontal direction. The driving assembly is connected to at least one of the upper punching die 10 and the lower punching die 20 and is used to drive the upper punching die 10 and the lower punching die 20 to move closer to or further away from each other.
[0038] For example, such as Figure 1 , Figure 2 and Figure 5As shown, the upper punching die 10 includes an upper die base 100 and a punching structure 200; the lower punching die 20 includes a lower die base 300 and a support assembly 400. The lower die base 300 is provided with a front-to-back extending bearing groove 310. The support assembly 400 includes a driving structure 410 and a clamping structure 420. The clamping structure 420 is located on the rear side of the bearing groove 310. The driving structure 410 is connected to the clamping structure 420 and is used to drive the clamping structure 420 to move in the front-to-back direction. The driving assembly is connected to the upper punching die 10 and is used to drive the upper punching die 10 to perform lifting and lowering movements.
[0039] When the punching device of this application is in operation, the tubular part is placed in the bearing groove 310 extending in the front-back direction. Under the drive of the drive structure 410, the clamping structure 420 moves forward to approach and clamp the preset area of the tubular part wall. The preset area of the tubular part wall is the area where the subsequent punching structure 200 needs to punch holes in the tubular part wall. Then, under the drive of the drive assembly, the upper punching die 10 can move downward to approach the lower punching die 20 and bring the punching structure 200 close to the tubular part in the bearing groove 310. Then, the punching structure 200 can punch holes in the preset area of the tubular part wall.
[0040] It is understood that in the punching device of this application, before the punching structure 200 punches the preset area of the tubular component wall, the clamping structure 420 can clamp and support the preset area of the tubular component wall, thereby reducing the degree of deformation of the tubular component wall during the operation of the punching structure 200.
[0041] In some embodiments of this utility model, reference is made to Figure 6 The punching structure 200 includes a punch 210 and a cylinder 220. The cylinder 220 is connected to the punch 210 and is used to drive the punch 210 to punch the tubular part.
[0042] In some embodiments of this utility model, the clamping structure 420 is slidably disposed on the lower mold base 300 along a preset horizontal direction; the driving structure 410 includes a first driving block 411, which is connected to the clamping structure 420. The first driving block 411 is provided with an abutting inclined surface 411a. The upper mold base 100 is provided with a second driving block 110, which is located directly above the abutting inclined surface 411a. Under the drive of the driving component, the second driving block 110 can follow the upper mold base 100 downward and approach and abut against the abutting inclined surface 411a, so that the second driving block 110 can push the first driving block 411 along the preset horizontal direction to approach the bearing groove 310 through the abutting inclined surface 411a.
[0043] For example, such as Figure 2 , Figure 3 and Figure 5As shown, the clamping structure 420 is slidably disposed on the lower mold base 300 in the front-back direction. The driving structure 410 includes a first driving block 411, which has an abutting inclined surface 411a extending forward and upward. The first driving block 411 is disposed on the rear side of the clamping structure 420 and connected to the rear end of the clamping structure 420. The upper mold base 100 is provided with a second driving block 110, which is located directly above the abutting inclined surface 411a.
[0044] Furthermore, under the drive of the drive assembly, the upper punching die 10 can move downwards towards the lower punching die 20. During the process of the upper punching die 10 moving towards the lower punching die 20, the second drive block 110 can approach and abut against the abutting inclined surface 411a on the first drive block 411. Under the push of the second drive block 110, the first drive block 411 can drive the clamping structure 420 to move forward, so that the clamping structure 420 can approach and clamp the tubular part in the bearing groove 310.
[0045] It is understood that the setting of the abutting inclined surface 411a on the first driving block 411 enables the driving component to drive the upper punching die 10 to approach the lower punching die 20, and the upper punching die 10 to simultaneously drive the clamping structure 420 to approach the tubular part in the bearing groove 310. This reduces the number of driving sources installed in the punching device of this application, reduces the manufacturing cost of the punching device of this application, and simplifies the overall structure of the punching device of this application.
[0046] In a further embodiment of this utility model, reference is made to... Figure 5 The second drive block 110 is provided with a drive ramp 111 adapted to abut the ramp 411a.
[0047] Furthermore, during the process of the driving component driving the upper punching die 10 to approach the lower punching die 20, the driving inclined surface 111 on the second driving block 110 can approach and abut against the abutting inclined surface 411a on the first driving block 411, and under the action of the driving inclined surface 111 and the abutting inclined surface 411a, the second driving block 110 can drive the first driving block 411 to move forward.
[0048] It is understandable that the setting of the driving inclined surface 111 can increase the force-bearing area between the first driving block 411 and the second driving block 110, thereby reducing the damage to the first driving block 411 and the second driving block 110 during the mutual contact process.
[0049] It should be noted that by setting an abutting inclined surface 411a on the first driving block 411, although the second driving block 110 can push the first driving block 411 forward through the abutting inclined surface 411a, the first driving block 411 cannot automatically reset after moving forward.
[0050] Based on the above problems, in some embodiments of this utility model, reference is made to... Figure 2 and Figure 3 The support assembly 400 also includes an elastic reset member 430, which is connected to the clamping structure 420 and the lower mold base 300 respectively, and is used to provide an elastic force that moves the clamping structure 420 away from the bearing groove 310 in a preset horizontal direction.
[0051] Understandably, after the punching structure 200 completes the punching of the tubular part in the bearing groove 310, the driving component can drive the upper punching die 10 upward away from the lower punching die 20. During this process, the second driving block 110 moves upward away from the first driving block 411. Without the abutting action of the second driving block 110, the clamping structure 420 can drive the first driving block 411 to move backward under the elastic force of the elastic reset member 430, so that the clamping structure 420 moves away from the tubular part in the bearing groove 310 and realizes the reset of the first driving block 411 and the clamping structure 420.
[0052] In one specific embodiment of this utility model, the elastic reset member 430 is a nitrogen spring.
[0053] Understandably, nitrogen springs are small in size, have high elasticity, operate smoothly, and have a long service life.
[0054] In order to facilitate the sliding of the clamping structure 420 relative to the lower mold base 300 in the front-back direction, in some embodiments of the present invention, the lower mold base 300 is provided with a sliding groove extending in the front-back direction, and the clamping structure 420 is slidably disposed in the sliding groove.
[0055] It is understandable that the design of the slide groove serves two purposes. First, the groove wall can limit the clamping structure 420 to the left and right, allowing the clamping structure 420 to slide accurately in the front-back direction under the drive of the first drive block 411. Second, placing the clamping structure 420 in the slide groove can reduce the overall height of the clamping structure 420, thereby allowing the overall volume of the punching die of this application to be smaller.
[0056] In some embodiments of this utility model, reference is made to Figure 3 The clamping structure 420 includes a mounting base 421, a first clamping member 422, a second clamping member 423, and a driver. The first clamping member 422 and the driver are both disposed on the mounting base 421. A clamping area for accommodating a predetermined area of the tubular member is formed between the second clamping member 423 and the first clamping member 422. The second clamping member 423 can extend into the pipe of the tubular member. The driver is connected to the second clamping member 423 and is used to drive the second clamping member 423 to move closer to the first clamping member 422.
[0057] Furthermore, driven by the drive structure 410, the clamping structure 420 can move forward so that the second clamping member 423 extends into the pipe of the tubular member, and the first clamping member 422 is located outside the pipe of the tubular member. At this time, the preset area of the tubular member wall can be located between the first clamping member 422 and the second clamping member 423. Driven by the driver, the second clamping member 423 can approach the first clamping member 422 so that the first clamping member 422 can cooperate with the second clamping member 423 to clamp the preset area of the tubular member wall.
[0058] It should be noted that the tubular component is provided with a through hole that allows the punch 210 of the punching structure 200 to extend into the tubular component pipe, and the through hole is directly opposite the preset area of the tubular component. Since the preset area of the tubular component wall is sandwiched between the first clamping member 422 and the second clamping member 423, it is difficult for the punch 210 of the punching structure 200 to punch the preset area of the tubular component wall.
[0059] Based on the above problems, in a further embodiment of this utility model, referring to Figure 4 The second clamping member 423 is provided with a clearance hole 423a that allows the punch 210 of the punching structure 200 to pass through.
[0060] Understandably, when the punching structure 200 punches the preset area of the tubular component, the punch 210 can move through the through hole and the clearance hole 423a to punch the preset area of the tubular component under the drive of the cylinder 220.
[0061] It should be noted that after punching the preset area of the tubular part in the punching structure 200, waste material will be generated. If this waste material cannot be removed in time, it will remain inside the tubular part and affect the subsequent processing of the tubular part.
[0062] Based on the above problems, in some embodiments of this utility model, reference is made to... Figure 4 The first clamping member 422 is provided with a waste discharge hole 422a facing the clearance hole 423a, and the lower mold base 300 is provided with a waste discharge channel, which is connected to the waste discharge hole 422a.
[0063] Furthermore, driven by the cylinder 220, after the punch 210 punches the preset area of the tubular component wall, the generated waste material can enter the waste discharge hole 422a of the first clamping member 422 under the drive of the punch 210, and enter the waste discharge channel of the lower die base 300 along the waste discharge hole 422a, thereby realizing the discharge of waste material.
[0064] In some embodiments of this invention, the actuator is a nitrogen spring.
[0065] Understandably, nitrogen springs are small in size, have high elasticity, operate smoothly, and have a long service life.
[0066] In some embodiments of this utility model, reference is made to Figure 5 The upper mold base 100 is provided with a limiting groove 120 adapted to the tubular component.
[0067] It is understandable that by providing a limiting groove 120 on the upper die holder 100, after the driving component drives the upper punching die 10 to approach the lower punching die 20, the limiting groove 120 and the bearing groove 310 can cooperate to position the tubular part in the vertical and left-right directions, so as to reduce the probability of the tubular part shifting during the punching process.
[0068] The tubular component production line provided according to the second aspect of the present invention includes the punching device provided in the first aspect of the present invention.
[0069] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
