[0016] Beneficial Effects

[0017] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0018] (1) The present invention provides an integrated continuous die for cutting and deburring, wherein a conveying mechanism is provided in the continuous die so that the processes of waste material cutting and deburring of the cut surface of the product can be completed and carried out simultaneously in one set of continuous dies, which not only saves the investment in a set of deburring dies, but also does not require time and labor to deburr the products cut from the continuous die, and the deburring efficiency of the continuous die is high.

[0019] (2) The present invention provides an integrated continuous die for cutting and deburring, wherein a clamping block cooperating with a spring is provided in the clamping groove, so that when the clamping jaws clamp the product, as the clamping cylinder is continuously clamped, the pressure head of the clamping block gradually compresses the spring, thereby causing the tails of the two clamping blocks on one jaw of the clamping jaw to gradually approach the corresponding proximity sensor. When the pressure head moves to be flush with the bottom of the clamping groove, the proximity sensor detects the pressure block and transmits the signal to the controller. When the controller receives the signals of the two proximity sensors at the same time, it controls the clamping cylinder to stop clamping the product. Here, through the coordinated action of the pressure block, the spring and the proximity sensor, when clamping the product, not only a pair of clamping grooves are used to clamp the product, but also the pressure block in the clamping groove is also pressed against the product under the action of the spring, thereby improving the clamping effect of the product. More importantly, during the product clamping process, when the pressure head moves to be flush with the bottom of the clamping groove, the proximity sensor can be used to feed back this to the controller, so that the controller controls the clamping cylinder to stop clamping, thereby clamping the product without deforming the product clamp.

[0040] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.

[0041] Example 1

[0042] like Figure 1 , Figure 2 , Figure 3 , Fig.11 and Fig.12 As shown, a cutting and deburring integrated continuous die of the present embodiment comprises a controller, a lower die and an upper die fixed on a press, a cutting station 01 and a deburring station 02 are provided on the upper die and the lower die in sequence correspondingly, and a product blanking port 05 is also provided on the rear side of the deburring station 02. In the present embodiment, the cutting station 01 on the lower die comprises a positioning seat located on the lower die base, a product supporting surface, a waste material blanking port 011 and a product supporting surface are provided on the positioning seat in sequence along the direction of incoming materials, and the waste material blanking port 011 passes through the lower die base; the cutting station 01 on the upper die comprises a punch which cooperates with the above-mentioned waste material blanking port 011 to cut off the waste material. The deburring station 02 on the lower die includes a support block 021 which is located on the same straight line as the above-mentioned positioning seat and is lower than the positioning seat. The upper end surface of the support block 021 is provided with a positioning groove which runs through the width direction of the support block 021 and is used for deburring the product. The bottom of the positioning groove is provided with a plurality of push rods 023 which pass through the support block 021 and the lower die base in sequence. Specifically, in this embodiment, the bottom of the positioning groove is provided with four push rods 023, and the four push rods 023 are distributed in a cross shape. A return spring is sleeved on the push rod 023, which can lift the product and make the product equal in height with the product on the above-mentioned product support surface; two guide pillars 022 lower than the positioning seat are provided on each side wall of the two side walls of the positioning groove, and a guide inclined surface 0221 and a vertical fixed surface 0222 are provided on the end surface of the guide pillar 022 close to the positioning groove from top to bottom, and the guide inclined surface 0221 is an inclined surface inclined downward from the direction close to the positioning groove; the deburring station 02 on the upper mold includes a pressing block cooperating with the positioning groove and a guide matching hole cooperating with the guide pillar 022.

[0043] The integrated continuous mold of this embodiment also includes a conveying mechanism 04, which includes a clamping cylinder 044 whose clamping jaws 045 can clamp the product, and the clamping jaws 045 are provided with two pairs of clamping grooves 4521 corresponding to the products on the cutting station 01 and the products on the deburring station 02 respectively. The cylinder body of the clamping cylinder 044 is fixed on the connecting plate 043, and the connecting plate 043 is fixed on the piston rod of the conveying cylinder 042 which can be extended and retracted in the direction of the incoming material, and the cylinder body of the conveying cylinder 042 is fixed on the lower mold base through the L-shaped fixing plate 041; wherein, a feeding position sensor 03 is also provided on the lower mold base and on one side of the cutting station 01, and the feeding position sensor 03, the press, the clamping cylinder 044, and the conveying cylinder 042 are all electrically connected to the controller.

[0044] During use, when the feeding position sensor 03 detects that there is a material strip on the product support surface of the positioning seat near the deburring station 02, the signal is transmitted to the controller, and the controller controls the press to move the lower die downward to simultaneously remove the waste and deburr the cut surface of the product. When the press completes the waste removal and deburring the cut surface of the product, the controller controls the transport cylinder 042 to extend, and when the front and rear pairs of clamping grooves 4521 on the clamping jaws of the clamping cylinder 044 are respectively aligned with the products on the cutting station 01 and the deburring station 02, the controller then controls the clamping cylinder 044 to clamp the cutting station 01 and the deburring station 02. For the product on the burring station 02, after the clamping cylinder 044 clamps the product, the controller controls the transport cylinder 042 to retract and when the products on the front and rear pairs of clamping grooves 4521 on the clamping jaws of the clamping cylinder 044 are aligned with the deburring station 02 and the product blanking port 05 respectively, the controller controls the clamping cylinder 044 to release. At this time, the products on the front and rear pairs of clamping grooves 4521 fall into the deburring station 02 and the product blanking port 05 respectively. At the same time, the material strip is sent to the product support surface of the positioning seat close to the deburring station 02, and then the above steps are repeated to complete the cutting of the entire material strip and the product deburring process.

[0045] It should be noted that: in this embodiment, a conveying mechanism is provided in the continuous die, so that the processes of waste removal of the product and deburring the cut surface of the product can be completed and carried out simultaneously in a set of continuous dies, which not only saves the investment in a set of deburring dies, but also the products cut from this continuous die do not need to invest time and manpower in deburring, and the deburring efficiency of this continuous die is high.

[0046] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, each jaw of the clamping jaw 045 of the present embodiment includes a support arm 0451, a pressing block 0453 and a clamping head 0452 provided with two clamping grooves 4521. The support arm 0451 is provided with two groups of coordination grooves corresponding to the above two clamping grooves one by one. The coordination grooves include a first arc guide groove 4511 and a U-shaped guide groove 4512 which are sequentially arranged on the support arm 0451 from the inside to the outside. The outside of the two U-shaped guide grooves 4512 of one of the jaws of the clamping jaw 045 is provided with a proximity sensor 04 54, the proximity sensor 0454 is fixed on the support arm 0451 through a connecting rod, and the proximity sensor 0454 is electrically connected to the controller; the bottom of each clamping groove 4521 and through it from the inside to the outside are sequentially provided with a pressure head guide hole 4522 and a circular avoidance hole 4523, and the upper clamping arm of each clamping groove 4521 has an extension extending outward, and the two extensions are fixedly connected by a connecting plate, and the lower end surface of the extension is provided with a second arc guide groove 4524 that passes through the length direction of the extension;

[0047] When the support arm 0451 is connected to the chuck 0452, the second circular arc guide groove 4524 and the first circular arc guide groove 4511 form a circular hole, and the circular hole and the circular avoidance hole 4523 together form an avoidance hole for the spring 0455 to retract and allow the pressure head 4531 on the clamping block 0453 to pass through, and a step surface is formed between the end of the avoidance hole away from the circular avoidance hole 4523 and the U-shaped guide groove 4512, and one end of the pressure head 4531 of the above-mentioned clamping block 0453 cooperates with the pressure head guide hole 4522, and its connecting section 5432 passes through the spring 0455 in the avoidance hole and cooperates with the U-shaped guide groove 4512, and the limiting portion 5433 at its end abuts against the side of the support arm 0451, wherein one end of the spring abuts against the pressure head 4531 and when the spring 0455 is in a natural state, the pressure head 4531 extends out of the pressure head guide hole 4522, and the other end of the spring 0455 abuts against the above-mentioned step surface.

[0048] It needs to be explained that: in this embodiment, a clamping block 0453 cooperating with the spring 0455 is set in the clamping groove 4521, so that when the clamping jaw 045 clamps the product, as the clamping cylinder 044 continues to clamp, the pressure head 4531 of the clamping block 0453 gradually compresses the spring 0455, so that the tails of the two clamping blocks 0453 on one jaw of the clamping jaw 045 gradually approach the corresponding proximity sensor 0454, and when the pressure head 4531 moves to be flush with the bottom of the clamping groove 4521, the proximity sensor 0454 detects the clamping block 0453 and transmits this signal to the controller, and when the controller receives the signals of these two proximity sensors 0454 at the same time, it controls the clamping cylinder 044 to stop clamping the product. Here, through the cooperation of the clamping block 0453, the spring 0455 and the proximity sensor 0454, when clamping the product, not only is the pair of clamping grooves 4521 used to clamp the product, but the clamping block 0453 in the clamping groove 4521 is also pressed tightly against the product under the action of the spring 0455, thereby improving the clamping effect of the product. More importantly, during the product clamping process, when the pressure head 4531 moves to be flush with the bottom of the clamping groove 4521, the proximity sensor 0454 can be used to feed back this to the controller, so that the controller controls the clamping cylinder 044 to stop clamping, thereby clamping the product without deforming the product clamp.

[0049] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
