Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and particularly to a rotary stamping device. Background Art

[0002] In the stamping manufacturing process of sheet metal parts, metal blanks are usually obtained by cutting with various dies. Among them, blanking dies are mainly used to manufacture metal sheet blanks from the original material sheets and form the final required-shaped stamping parts in subsequent stamping operations. The stamping parts are usually stacked for storage after the stamping operation.

[0003] In daily production, when stamping parts are stacked for storage, multiple identical stamping parts will fit very tightly together after being stacked, making it difficult to separate them, which brings considerable difficulty to subsequent part picking. To solve such problems, special treatments are usually made in the design of stamping parts. For example, without affecting the final use of the stamping parts, different shaped surfaces are formed in several local areas of the stamping parts produced successively. Usually, several depressions are pressed at different positions on the stamping parts, and the positions of the depressions between adjacent two stamping parts are different, so that the gap between the stamping parts can be increased for material picking during storage. In order to achieve different positions of the depressions between the stamping parts, the existing stamping dies usually use a driving device to drive a ratchet wheel to rotate to achieve the displacement of the depressions. Although this structure can achieve the displacement of the depressions, due to the need for an additional driving mechanism for driving, the overall cost of the stamping die is relatively high.

[0004] Therefore, there is an urgent need for a rotary stamping device to solve the problems in the prior art. Summary of the Invention

[0007] A rotary stamping device, comprising:

[0008] A sleeve mechanism, including a mounting seat and a sleeve, the sleeve is connected to the mounting seat;

[0009] A steering mechanism, including a first elastic driving member and a rotating shaft assembly, one end of the rotating shaft assembly extends into the sleeve and can slide along the axial direction of the sleeve, the first elastic driving member is arranged in the sleeve and connected to the mounting seat, and the driving end of the first elastic driving member abuts against the rotating shaft assembly, and the first elastic driving member is configured to drive the rotating shaft assembly away from the mounting seat;

[0010] A stamping mechanism, connected to one end of the rotating shaft assembly away from the mounting seat;

[0011] A reset driving mechanism, connected to the sleeve. A guide rail is provided at one end of the rotating shaft assembly extending into the sleeve. The driving end of the reset driving mechanism extends into the sleeve and is slidably connected to the guide rail. The reset driving mechanism is configured to drive the stamping mechanism to rotate through a preset angle during the reset process of the rotating shaft assembly after stamping.

[0012] Optionally, the rotating shaft assembly includes a rotating shaft and a rotating rod. The guide rail is provided on the rotating shaft. The guide rail includes a plurality of guide grooves and a plurality of turning grooves. The plurality of guide grooves are circumferentially spaced apart on the rotating shaft.

[0013] Optionally, the depth of the guide groove at the end away from the mounting seat is greater than the depth of the guide groove at the end close to the mounting seat.

[0014] Optionally, a groove is provided at one end of the rotating rod close to the rotating shaft. The driving end of the first elastic driving member passes through the rotating shaft and abuts against the bottom of the groove.

[0015] Optionally, the reset driving mechanism includes a mounting bracket and a second elastic driving member. The mounting bracket is connected to the sleeve. The second elastic driving member is connected to the mounting bracket. The driving end of the second elastic driving member extends into the sleeve and is slidably connected to the guide rail.

[0016] Optionally, both the first elastic driving member and the second elastic driving member are nitrogen springs.

[0017] Optionally, a mounting plane is provided on the outer wall of the sleeve. The mounting bracket is fastened to the mounting plane by bolts.

[0018] Optionally, through holes are provided on the mounting plane. The driving end of the second elastic driving member passes through the through holes and extends into the sleeve.

[0019] Optionally, the mounting bracket includes a mounting cylinder and a baffle. One end of the mounting cylinder is connected to the sleeve, and the other end is provided with a baffle. The second elastic driving member is arranged in the mounting cylinder and is connected to the baffle.

[0020] Optionally, the stamping mechanism includes an end plate and a stamping head. The end plate is connected to the rotating shaft assembly, and a limiting space is formed between the end plate and the rotating shaft assembly. The stamping head is disposed in the limiting space.

[0021] Advantageous effects:

[0022] For the rotary stamping device provided by the present invention, when the stamping mechanism stamps a part, the stamping mechanism drives the rotating shaft assembly to move upward relative to the sleeve, and the rotating shaft assembly compresses the driving end of the first elastic driving member.

At the same time, the reset driving mechanism of the rotary stamping device can drive the stamping mechanism to rotate during the reset process of the rotating shaft assembly, realizing the transmission of the machine, which can further reduce the cost and improve the stamping efficiency.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of convenience of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0032] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above the top of", and "on the top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below the bottom of", and "under the bottom of" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0034] In the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "left", and "right" are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0035] In order to solve the problem that when multiple identical stamping parts are stacked together, they will fit very tightly and are not easy to separate, which brings considerable difficulty to the subsequent picking of parts. This embodiment provides a rotary stamping device for stamping parts so as to form dimples on the parts, increase the distance between two adjacent plates, and facilitate the picking and placing of parts. As Figure 1 and Figure 2As shown in the figure, the rotary stamping device includes a sleeve mechanism 100, a steering mechanism 200, a stamping mechanism 400 and a reset mechanism. The sleeve mechanism 100 includes a mounting seat 120 and a sleeve 110. The sleeve 110 is connected to the mounting seat 120 by bolts, and the mounting seat 120 is used to be mounted on the output end of the stamping equipment. The steering mechanism 200 includes a first elastic driving member 210 and a rotating shaft assembly 220. The upper end of the rotating shaft assembly 220 extends into the sleeve 110 and can slide axially along the sleeve 110. The first elastic driving member 210 is disposed inside the sleeve 110. The upper end of the first elastic driving member 210 is fixed to the mounting seat 120 by a reed 130 and bolts. The driving end of the first elastic driving member 210 abuts against the rotating shaft assembly 220. The stamping mechanism 400 is connected to the lower end of the rotating shaft assembly 220. During stamping, the rotating shaft assembly 220 moves upward relative to the sleeve 110. After stamping is completed, the elastic force of the first elastic driving member 210 can drive the rotating shaft assembly 220 away from the mounting seat 120 to realize the reset of the rotating shaft assembly 220. A guide rail is provided at one end of the rotating shaft assembly 220 that extends into the sleeve 110. The reset driving mechanism 300 is connected to the sleeve 110. The driving end of the reset driving mechanism 300 extends into the sleeve 110 and is slidably connected to the guide rail. The reset driving mechanism 300 is used to drive the stamping mechanism 400 to rotate by a preset angle during the reset process of the rotating shaft assembly 220 after stamping. When stamping another part, since the rotating shaft assembly 220 drives the stamping mechanism 400 to rotate, the stamping position of the other part is different from the previous stamping position. When multiple parts are stacked, the distance between adjacent two parts is increased, which is more convenient for taking materials. At the same time, the reset driving mechanism 300 of the rotary stamping device can drive the stamping mechanism 400 to rotate during the reset process of the rotating shaft assembly 220, realizing the mechanical transmission, which can further reduce the cost and improve the stamping efficiency.

[0036] Preferably, as Figure 1 and Figure 3As shown in the figure, the rotating shaft assembly 220 includes a rotating shaft 221 and a rotating rod 222. The guide rail is arranged on the rotating shaft 221. The guide rail includes a plurality of guide grooves 2211 and a plurality of steering grooves 2212. The plurality of guide grooves 2211 are arranged on the rotating shaft 221 at intervals along the circumferential direction of the rotating shaft 221. Each guide groove 2211 is parallel to the axis of the rotating shaft 221. A steering groove 2212 is arranged between two adjacent guide grooves 2211. One end of the steering groove 2212 is connected to the lower end of one of the two adjacent guide grooves 2211, and the other end of the steering groove 2212 is connected to the upper end of the other of the two adjacent guide grooves 2211. And the plurality of steering grooves 2212 are parallel to each other, which can ensure that during the stamping process, each time the rotating shaft assembly 220 is reset, the driving end of the reset driving mechanism 300 can drive the rotating shaft 221 to rotate through a preset angle, so as to realize the mechanical continuous rotation of the rotating shaft assembly 220 and improve the stamping efficiency.

[0037] Preferably, the depth of the lower end of the guide groove 2211 is greater than the depth of the upper end of the guide groove 2211, so that the driving end of the reset driving mechanism 300 can smoothly slide from the lower end of the guide groove 2211 into the steering groove 2212 during the reset process of the rotating shaft 221 and drive the rotating shaft 221 to rotate.

[0038] Preferably, as Figure 3 shown, the rotating shaft 221 is a hollow structure. The rotating rod 222 is connected to the rotating shaft 221 by bolts. A groove 2221 is arranged at the upper end of the rotating rod 222. The driving end of the first elastic driving member 210 passes through the rotating shaft 221 and abuts against the bottom of the groove 2221. The groove 2221 can limit the driving end of the first elastic driving member 210 and prevent the driving end of the first elastic driving assembly from shifting.

[0039] Preferably, as Figure 3 shown, the reset driving mechanism 300 includes a mounting bracket 310 and a second elastic driving member 320. The mounting bracket 310 is connected to the sleeve 110. The second elastic driving member 320 is connected to the mounting bracket 310. The driving end of the second elastic driving member 320 extends into the sleeve 110 and is slidably connected to the guide rail, so as to realize the mechanical rotation of the stamping mechanism 400 during the stamping process and ensure that there is enough clearance between two adjacent parts after stamping, which is convenient for subsequent part taking.

[0040] Preferably, both the first elastic driving member 210 and the second elastic driving member 320 are nitrogen gas springs. A nitrogen gas spring is a new type of elastic component with high-pressure nitrogen as the working medium. It is small in size, large in elastic force, long in stroke, stable in operation, precise in manufacturing, long in service life, has a gentle elastic force curve, and does not require pre-tightening, etc. It can perform tasks that are difficult for conventional elastic components such as metal springs, rubber, and air cushions, simplifies the design and manufacturing of the rotary stamping device, facilitates the installation and adjustment of the rotary shaft assembly 220, extends the service life of the rotary stamping device, and ensures that the working process of the rotary stamping device is more stable. It should be noted that the nitrogen gas spring is a mature technical means in the field, and the specific structure and working principle of the nitrogen gas spring are not elaborated in this embodiment.

[0041] Preferably, as Figure 1 shown, an installation plane 111 is provided on the outer wall of the sleeve 110, and the installation bracket 310 is fastened to the installation plane 111 by bolts, which can prevent relative rotation between the installation bracket 310 and the sleeve 110, enabling the second elastic driving member 320 to operate smoothly and reliably.

[0042] Further, through holes 1111 are formed in the installation plane 111, and the driving end of the second elastic driving member 320 passes through the through holes 1111 and extends into the sleeve 110 to be slidably connected to the guide rail.

[0043] Preferably, as Figure 1 shown, the installation bracket 310 includes an installation cylinder 311 and a baffle 312. One end of the installation cylinder 311 is connected to the sleeve 110, and the other end is provided with a baffle 312. The second elastic driving member 320 is disposed in the installation cylinder 311 and connected to the baffle 312 by bolts. By covering the second elastic driving member 320 with the installation cylinder 311, it can protect the second elastic driving member 320, and at the same time prevent staff from touching the second elastic driving member 320, preventing the occurrence of safety accidents.

[0044] Preferably, the stamping mechanism 400 includes an end plate 410 and a stamping head 420. The end plate 410 is connected to the rotating rod 222 of the rotary shaft assembly 220 by screws 430. The end plate 410 and the end face of the rotating rod 222 enclose a limiting space, and the stamping head 420 is accommodated in the limiting space, thereby realizing the fixation of the stamping head 420. Specifically, the stamping head 420 can be circular, triangular, rectangular, etc. The shape of the stamping head 420 is not specifically limited in this embodiment.

[0045] The working principle of the rotary stamping device provided in this embodiment is as follows:

[0046] Step 1: Fix the mounting base 120 to the output end of the stamping equipment.

[0047] Step 2: Start the stamping equipment. The stamping equipment drives the rotary stamping device to move downward. The stamping head 420 approaches the part and abuts against the surface of the part. At this time, the stamping equipment continues to apply pressure, and the driving end of the first elastic driving member 210 will be pressed to contract, and the rotary shaft assembly 220 moves upward relative to the sleeve 110. The driving end of the second elastic driving member 320 slides along the guiding groove 2211 to the lower end of the guiding groove 2211. After the stamping head 420 stamps a dimple on the surface of the part, the stamping ends.

[0048] Step 3: The stamping equipment moves upward, and the rotary shaft assembly 220 will move downward for reset under the action of the elastic force of the first elastic driving member 210. At this time, the driving end of the second elastic driving member 320 slides from the bottom of the guiding groove 2211 into the steering groove 2212 to drive the rotary shaft 221 to turn. When the rotary shaft assembly 220 is completely reset, the driving end of the second elastic driving assembly is located at the upper end of the guiding groove 2211.

[0049] Step 4: Repeat Step 2 and Step 3 to stamp dimples at different positions of multiple parts to ensure convenient picking and placing between adjacent two parts.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
