Description

Technical Field

[0001] The invention relates to the technical field of continuous dies, in particular to a stamping type deburring continuous die. Background Art

[0002] Under the punching and shearing action of the continuous die, the sheet metal undergoes elastic deformation, plastic deformation, and then fracture separation. Due to the existence of the gap between the convex and concave dies, when the sheet metal is cut, the burrs that exceed the thickness of the sheet metal in the separation direction are usually called burrs (or burrs). The burrs that fly out of the end face of the material affect the product precision and aesthetics, and are likely to cause safety hazards and scratch workers.

[0003] There are many different ways to remove burrs from stamping parts: 1. Grinding to remove burrs. 2. Magnetic polishing to remove burrs. 3. Filing burrs, etc. These methods are time-consuming and labor-intensive. Usually, it is mainly necessary to reduce burrs by improving the quality of the materials used for punching convex and concave dies, improving the hardness of heat treatment, designing a reasonable gap between the convex and concave dies, and improving the processing accuracy and surface finish of the convex and concave dies. However, improving the quality of the convex and concave dies and improving the hardness of heat treatment will increase the cost. After a period of production and use, the convex and concave dies will still become blunt and burrs will appear on the products. The blunted convex and concave dies should be restored in time by flat grinding. After each flat grinding, the height dimensions of the convex and concave dies will decrease accordingly, and contoured gaskets need to be made to fill them. Summary of the invention

[0018] Two limit sealing plates are fixed on the top of the discharge lifting module, and the area between the two limit sealing plates is a product circulation area.

[0019] Advantages of the present invention:

[0020] (1) The present invention is provided with a burr pressing station, and the burrs protruding upward at the rear end of the product and the burrs protruding downward at the front end of the product are respectively pressed synchronously by an upper burr pressing punch and a lower burr pressing punch at the burr pressing station, and the upper burr pressing punch and the lower burr pressing punch both press the burrs of the product through the R angle, so that the burrs at the front end and the rear end of the product are flattened into a small R angle structure, thereby achieving the purpose of deburring, thereby producing a completely burr-free product;

[0021] (2) The present invention provides a lifting movable module at the deburring station. When deburring, the lifting movable module descends to separate the product at the cutting station from the product at the deburring station, thereby ensuring that the product is deburred while being stamped and cut. After the deburring is completed, the lifting movable module drives the product to move upward and reset, thereby achieving the purpose of continuing to transport and discharge the material, thereby ensuring the continuous stamping work of the continuous die and the production efficiency of the continuous die.

[0022] (3) The rear end of the floating support block of the present invention is an inclined surface, so that when the lifting movable module drives the product at the deburring station to move downward, the front end of the product can move backward along the inclined surface of the floating support block under the action of gravity and be positioned at the deburring station. On the one hand, a gap is generated between the product at the deburring station and the product at the front cutting station to prevent the upper burr pressing punch from pressing the product at the cutting station. On the other hand, the upper burr pressing punch and the lower burr pressing punch can accurately position the product to achieve the deburring operation.

[0023] (4) A positioning pin is provided on the lower punch of the deburring die of the present invention. On the one hand, the positioning pin blocks the rear end of the product moving backward along the inclined surface of the floating support block, so that the product is accurately positioned at the deburring station, thereby achieving accurate deburring operation. On the other hand, when the product moves to the discharge station, the front end of the product is supported on the positioning pin, and the rear end is supported on the discharge lifting module. When the discharge lifting module moves downward, the rear end of the product moves downward accordingly, and the rear end of the product tilts downward, so that the product slides into the discharge chute through the discharge gap below the blocking block, thereby achieving the purpose of rapid discharge.

[0024] (5) The present invention is provided with two inverted L-shaped limit blocks on the floating support block, two inverted L-shaped guide blocks are provided at the deburring station, and two limit sealing plates are fixed on the top of the discharge lifting module, all of which ensure the accuracy of product guiding transportation and avoid product stacking.

The horizontal height of the top of the inclined surface is consistent with the horizontal height of the horizontal support surface. There is an angle of 36 degrees between the inclined surface and the vertical surface. The horizontal support surface of the floating support block 5 is divided into a cutting area 51 and a guide area 52 from front to back. The upper cutting punch 4 is vertically facing the cutting area 51 of the horizontal support surface of the floating support block 5. Two inverted L-shaped limit blocks 14 are fixed on the guide area 52 of the horizontal support surface of the floating support block 5. The two inverted L-shaped limit blocks 14 are horizontally The height difference between the bottom horizontal plane of the flat part and the horizontal supporting plane of the floating support block 5 is greater than the thickness of one product and less than the thickness of two products. The vertical parts of the two inverted L-shaped limit blocks 14 are the product circulation area. The floating support block 5 is elastically connected to the lower die 2 through a spring. When the floating support block 5 is not subjected to force, the horizontal height of the top of the floating support block is higher than the horizontal height of the top of the lower die 2 and is equal to the guide conveying height of the continuous die. When the floating support block 5 is squeezed by the upper die 1, the floating support block 5 is squeezed and moved downward until it is lower than the horizontal height of the top of the lower die 2.

[0037] See Figure 6The bottom surface of the upper punch 6 for pressing the burrs is a stepped surface, the horizontal height of the front end portion 61 of the bottom of the upper punch 6 for pressing the burrs is lower than the horizontal height of the rear end portion 62 of the bottom, and the stepped surfaces of the upper punch 6 for pressing the burrs are transitioned through R angles 63; Figure 7 , the top surface of the lower punch 9 for pressing burrs is a stepped surface, the horizontal height of the front end portion 91 of the top of the lower punch 9 for pressing burrs is lower than the horizontal height of the rear end portion 92 of the top of the lower punch 9 for pressing burrs, the stepped surfaces of the lower punch 9 for pressing burrs are transitioned through an R angle 93, the horizontal height of the front end portion 91 of the top of the lower punch 9 for pressing burrs is equal to the horizontal height of the top of the lower die 2, two upwardly protruding positioning pins 94 are arranged on the rear end portion 92 of the top surface of the lower punch 9 for pressing burrs, and the positioning pins 94 are adjacent to the R angle of the stepped surface of the lower punch 9 for pressing burrs, the two positioning pins 94 are adjacent to the two ends of the lower punch 9 for pressing burrs, respectively, and the horizontal heights of the top ends of the two positioning pins 94 are equal and are not greater than the guide conveying height of the continuous die;

[0038] See Figure 8 When the lifting movable module 8 is lifted to the highest position, the horizontal height of the top of the lifting movable module 8 is equal to the guide conveying height of the continuous mold. When the lifting movable module 8 is at the lowest position, the horizontal height of the top of the lifting movable module 8 is lower than the horizontal height of the top of the lower mold 2. The discharge lifting module 10 and the lifting movable module 8 are synchronously lifted and driven by the same lifting cylinder 13. The support horizontal height of the top of the discharge lifting module 10 is always consistent with the support horizontal height of the top of the lifting movable module 8.

[0039] The blocking block 11 is located directly above the top of the discharge chute 12 and a discharge gap is set between the two. The guide conveying height of the continuous mold plus the thickness of the product is greater than the horizontal height value of the bottom end of the blocking block 11, that is, when the product is horizontally positioned at the guide conveying height, it is blocked by the blocking block 11.

[0040] Among them, two inverted L-shaped guide blocks 15 (see Figure 3 ), the product circulation area is between the two inverted L-shaped guide blocks 15, when the lifting active module 8 is at the highest position, the two inverted L-shaped guide blocks 15 are respectively located at the two ends of the lifting active module 8, and the height difference between the bottom horizontal plane of the horizontal part of the two inverted L-shaped guide blocks 15 and the top support horizontal plane of the lifting active module 8 is greater than the thickness of one product and less than the thickness of two products; two limit sealing plates 16 (see Figure 8 ), the area between the two limiting sealing plates 16 is the product circulation area.

[0041] Working principle of the present invention:

[0042] (1) When the continuous mold is in the maximum open state, the lifting cylinder 13 drives the lifting movable module 8 and the discharge lifting module 10 to move downward synchronously until the support level of the lifting movable module 8 and the top of the discharge lifting module 10 is lower than the top of the lower mold 2. At this time, the front end of the product at the discharge station is supported on the positioning pin 94, and the rear end is supported on the discharge lifting module 10. When the discharge lifting module 10 moves downward, the rear end of the product moves downward accordingly, and the rear end of the product tilts downward, so that the product slides into the discharge chute 12 through the discharge gap under the blocking block 11, thereby achieving the purpose of rapid discharge; at the same time, the product at the deburring station moves downward with the lifting movable module 8, and the front end of the product at the deburring station can move backward along the inclined surface 53 of the floating support block 5 and be positioned on the top of the lower mold 2, and the rear end of the product is blocked and positioned by the two positioning pins 94;

[0043] (2) When the upper die 1 moves downward and closes with the lower die 2, the punching punch on the upper die 1 punches the material strip 17 at the punching station, and at the same time, the upper cutting punch 4 presses down the floating support block 5, and the floating support block 5 is squeezed and moved downward until the horizontal support surface of the floating support block 5 is lower than the top surface of the upper cutting punch 3. The upper cutting punch 4 and the upper cutting punch 3 cooperate to cut the material strip 17 and the product at the cutting station. At the same time, the upper burr pressing punch and the lower burr pressing punch simultaneously press the burrs protruding upward at the rear end and the burrs protruding downward at the front end of the product at the deburring station, so as to achieve the purpose of removing the burrs;

[0044] (3) When the upper mold 1 moves up and has not yet reached the maximum opening state, the lifting cylinder 13 first drives the lifting movable module 8 and the discharge lifting module 10 to move up synchronously, thereby lifting the products at the deburring station and the discharge station to the guide conveying height. Then, when the upper mold 1 continues to move up for a distance and has not yet reached the maximum opening state, the feeder feeds the material, and the material belt 17 pushes forward the step distance of one product, so that the product at the deburring station moves to the discharge station. Due to the action of the blocking block 11, the front end of the product moved into the discharge station is supported on the two positioning pins 94, and the rear end is supported on the discharge lifting module 10. Finally, when the upper mold 1 moves up to the maximum opening state, the step (1) operation is repeated, thereby realizing the continuous stamping, cutting, deburring and discharge operations of the continuous mold.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
