[0032] In order to make the content of the present utility model easier to be clearly understood, the present utility model will be further described in detail below according to specific embodiments in conjunction with the drawings.

[0033] As Figures 1-6 shown, in this embodiment, a fin stamping and material receiving tooling is provided, including a base 1. A material receiving table 2 is slidably arranged on the base 1. A plurality of material receiving plates 3 are fixedly arranged on the material receiving table 2. A front limiting plate 4 and a rear limiting plate 5 are respectively slidably arranged on the front and rear sides of the material receiving plate 3. The front limiting plate 4 and the rear limiting plate 5 are arranged alternately. Two material receiving needles 6 are movably arranged on the material receiving plate 3.

[0034] As Figures 1-6 shown, in this embodiment, the base 1 is placed below the discharge port of the fin stamping equipment, so that the fins stamped by the stamping equipment fall from the discharge port onto the material receiving plate 3 on the lower base 1, and the fins can be sleeved on the two material receiving needles 6 on the material receiving plate 3.

[0035] As Figures 1-6 shown, in this embodiment, two supporting feet 11 for supporting the base 1 are formed by downward extension of both sides of the bottom of the base 1. A slide rail 12 is fixedly arranged on the upper side surface of the base 1. A chute 21 corresponding to the slide rail 12 is opened at the bottom of the material receiving table 2, so that the material receiving table 2 can slide on the base 1. A driving cylinder 7 is fixedly installed at the bottom of the base 1. A connecting block 22 is fixedly arranged on one side of the material receiving table 2. The output end of the driving cylinder 7 is fixedly connected with the connecting block 22, so that the driving cylinder 7 can drive the material receiving table 2 to slide on the base 1. By setting the driving cylinder 7, automatic control of the sliding of the material receiving table 2 is realized, and the position accuracy during the movement of the material receiving table 2 is improved.

[0036] As Figures 1-6 shown, in this embodiment, in order to improve the stability of the material receiving table 2 when sliding, the number of the slide rails 12 is two. In other embodiments not shown, the number of the slide rails 12 is not limited.

[0037] As Figures 1-6As shown in the figure, in this embodiment, a cavity 23 is formed in the material receiving table 2, and a plurality of sliding grooves 24 communicating with the cavity 23 are formed in the material receiving table 2. The number of the sliding grooves 24 corresponds to the number of the front limiting plate 4 and the rear limiting plate 5. A front limiting column 41 is fixedly connected to the bottom of the front limiting plate 4, and a rear limiting column 51 is fixedly connected to the bottom of the rear limiting plate 5. The front limiting column 41 and the rear limiting column 51 both pass through the sliding groove 24 and extend into the cavity 23, and the front limiting column 41 and the rear limiting column 51 can slide in the sliding groove 24, thereby driving the front limiting plate 4 and the rear limiting plate 5 to move relative to the material receiving plate 3.

[0038] As Figures 1-6 shown in the figure, in this embodiment, the front limiting plate 4 and the rear limiting plate 5 play a role in guiding and limiting the falling fins. The inclined surfaces are formed on the sides where the upper ends of the front limiting plate 4 and the rear limiting plate 5 are close to each other, which is convenient for the fins to fall.

[0039] As Figures 1-6 shown in the figure, in this embodiment, a driving assembly 8 for driving the front limiting column 41 and the rear limiting column 51 to move is arranged in the cavity 23. The driving assembly 8 includes a driving motor 81, a driving gear 82, a first rack 83 and a second rack 84. The driving motor 81 is fixedly installed on the side wall of the cavity 23, the driving gear 82 is fixedly sleeved on the output shaft of the driving motor 81, the first rack 83 and the second rack 84 are slidably installed on the side wall of the cavity 23, the first rack 83 and the second rack 84 are oppositely arranged on both sides of the driving gear 82, and the first rack 83 and the second rack 84 are both meshed with the driving gear 82, so that when the driving gear 82 rotates, it can drive the first rack 83 and the second rack 84 to move in the opposite direction. The first rack 83 is fixedly connected to the front limiting column 41, and the second rack 84 is fixedly connected to the rear limiting column 51. Therefore, when the driving motor 81 works, it can drive the front limiting plate 4 and the rear limiting plate 5 to move relative to the material receiving plate 3. At the same time, by using the forward and reverse rotation of the driving motor 81, the front limiting plate 4 and the rear limiting plate 5 can be simultaneously close to or away from the corresponding material receiving plate 3 to adjust the distance between the front limiting plate 4 and the rear limiting plate 5 according to the width of the processed fins. In other embodiments not shown, the driving assembly 8 can also be a screw drive or a hydraulic cylinder, or other driving methods well known to those skilled in the art, which will not be elaborated in this embodiment.

[0040] As Figures 1-6As shown in the figure, in this embodiment, a sliding channel 31 is formed in the material receiving plate 3. Two connecting seats 9 are slidably arranged in the sliding channel 31. The material receiving needle 6 is movably arranged in the connecting seat 9. Specifically, an installation part 61 is provided at the bottom of the material receiving needle 6. An installation groove 91 corresponding to the installation part 61 is formed in the connecting seat 9. An arc surface recessed inward is formed on the side peripheral surface of the installation part 61. Limiting grooves 92 communicating with the installation groove 91 are formed on two opposite side walls of the installation groove 91. Limiting balls 93 corresponding to the arc surface on the installation part 61 are slidably arranged in the limiting grooves 92. A spring 94 is fixedly connected to the side of the two limiting balls 93 facing away from each other. The other end of the spring 94 is fixedly connected to the side wall of the limiting groove 92. When the spring 94 is in a normal state, half of the limiting ball 93 is located in the installation groove 91. When the material receiving needle 6 is inserted into the installation groove 91 from top to bottom, the bottom of the installation part 61 touches the limiting ball 93, pushing the limiting ball 93 to retract into the limiting groove 92. At this time, the spring 94 is compressed by force. As the arc surface of the installation part 61 gradually reaches the limiting groove 92, the force on the spring 94 gradually decreases, and the spring 94 gradually resets. The limiting ball 93 abuts against the arc surface of the installation part 61 until the bottom of the installation part 61 abuts against the bottom wall of the installation groove 91, and then the material receiving needle 6 can be installed on the connecting seat 9. When it is necessary to replace the material receiving needle 6, only need to pull out the material receiving needle 6 upward and replace it with a new one.

[0041] As Figures 1-6 shown in the figure, in this embodiment, the material receiving needle 6 is installed on the connecting seat 9. The connecting seat 9 can slide in the sliding channel 31, so that the distance between the two material receiving needles 6 can be adjusted, and the positions of the two material receiving needles 6 can be adjusted according to the through holes on the punched fins.

[0042] The working process and principle of the utility model are as follows: the base 1 is placed under the discharge port of the fin stamping equipment, so that the frontmost material receiving plate 3 is located directly under the discharge port; the corresponding material receiving needle 6 is selected according to the size of the through hole on the stamped fin, and the material receiving needle 6 is installed in the mounting groove 91 from top to bottom, and the bottom of the mounting portion 61 touches the limiting ball 93, pushing the limiting ball 93 to retract into the limiting groove 92, at this time, the spring 94 is compressed, and as the arc surface of the mounting portion 61 gradually reaches the limiting groove 92, the force on the spring 94 gradually decreases, and the spring 94 gradually resets, and the limiting ball 93 abuts on the arc surface of the mounting portion 61 until the bottom of the mounting portion 61 abuts on the bottom wall of the mounting groove 91, and the material receiving needle 6 can be installed on the connecting seat 9; the two connecting seats 9 are moved so that the two connecting seats 9 slide in the sliding channel 31, and then according to the position of the through hole on the stamped fin, the two connecting seats 9 are moved. The position of the two material receiving needles 6 is adjusted; the driving motor 81 works to drive the driving gear 82 to rotate. Since the first rack 83 and the second rack 84 are relatively arranged on both sides of the driving gear 82, and the first rack 83 and the second rack 84 are meshed with the driving gear 82, the driving gear 82 can drive the first rack 83 and the second rack 84 to move in the opposite direction when rotating, so that the front limit plate 4 and the rear limit plate 5 are simultaneously close to or away from the corresponding material receiving plate 3, so as to adjust the distance between the front limit plate 4 and the rear limit plate 5 according to the width of the processed fins; start the stamping equipment, and the stamped fins fall on the lower material receiving plate 3 in turn, and the fins are sleeved on the material receiving needles 6. When the number of fins on the frontmost material receiving plate 3 reaches a certain number, the driving cylinder 7 drives the material receiving table 2 to move forward, so that the rear material receiving plate 3 moves to the bottom of the discharge port to continue the material receiving work.

[0043] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention.
