Description

Technical Field

[0001] This utility model relates to the field of deburring technology, and in particular to a deburring mechanism for alternating punching. Background Technology

[0002] The partition is an essential component of a diaphragm pump. During the production and processing of the partition, drilling and deburring are required. Currently, in the industry, the punching and deburring of through holes is generally done manually, which wastes manpower. With technological advancements, mechanical stamping with upper and lower dies has also emerged. For example, Chinese patent CN201621246053.2 discloses a mechanical deburring device for a fixed pressing block used in escalators. This device includes a base plate with a product placement fixture on it. A punching plate is positioned above the product placement fixture, and a fixing plate is connected above the punching plate. Five punching columns, corresponding to the positions of the through holes in the product to be processed, are positioned below the punching plate. A driving device is positioned above the fixing plate to drive its up and down movement. The product placement platform has punch holes corresponding to the punching columns, allowing the stamping columns to extend into them. This device deburrs the five through holes through the punching of the stamping columns. However, the stamping column set in the upper die will cause the removed burrs to remain on the tooling, requiring additional cleaning, which is time-consuming and labor-intensive. Utility Model Content

[0003] In view of this, the present invention provides a deburring mechanism with alternating punching to solve the above problems.

[0004] A deburring mechanism for partitions is disclosed, used for deburring several through holes on a partition. The mechanism includes a lower die assembly and an upper die assembly disposed on one side of the lower die assembly. The lower die assembly includes a lower die holder, at least four guide posts disposed at the corners of the lower die holder, a lower die movably inserted through the guide posts, at least four springs respectively sleeved on the guide posts, and several punches fixedly disposed on the lower die holder. The upper die assembly includes an upper die holder, an air passage plate disposed on the side of the upper die holder facing the lower die assembly, and an upper die disposed on the side of the air passage plate facing the lower die assembly. A groove matching the convex surface of the partition is formed on the side of the lower die away from the lower die holder. The punches are the same size as the through holes, and a cylindrical portion with a diameter smaller than the diameter of the through hole is provided at the end of the punch away from the lower die holder. Two of the punches, corresponding to the first and second positioning through holes, are each provided with a positioning part at their ends away from the lower die holder. The diameter of the positioning part is the same as the diameter of the through hole. Both the cylindrical part and the positioning part protrude from the lower die. The air passage plate has at least two interconnected air passages on its side away from the lower die holder.

[0005] Furthermore, two limiting plates are respectively provided at the ends of the four guide pillars away from the lower mold frame, and the two ends of one limiting plate are fixedly connected to the ends of the two guide pillars respectively.

[0006] Furthermore, one end of the spring abuts against the lower mold frame, and the other end abuts against the lower mold.

[0007] Furthermore, the upper mold frame is connected to the output end of an external drive cylinder.

[0008] Furthermore, the air circuit board has at least two air inlets on the side facing the upper mold frame, and the two air inlets are connected to two air pipe connectors.

[0009] Furthermore, the air passage is connected to the two air inlets.

[0010] Furthermore, the shape of the upper mold matches the concave surface of the partition row, and a plurality of punches are formed on it corresponding to a plurality of through holes on the partition row, and the punches are connected to the air passage.

[0011] Compared with existing technologies, the partition punching and deburring mechanism provided by this utility model positions the partitions using the grooves and two positioning parts, avoiding the need to completely fit each punch into each through hole, thus facilitating manual placement. During the downward pressing of the upper die assembly, the punches completely pass through the through holes on the partitions, thereby completing the deburring operation. The punching process requires no manual intervention, saving manpower. Furthermore, during the lifting process of the upper die assembly, the exhaust valve of the drive cylinder exhausts gas and introduces the gas into the punch holes, thereby blowing away the burrs and waste materials remaining in the punch holes, preventing material blockage and mold damage, thus achieving the function of waste gas utilization and saving energy.

[0016] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0017] like Figure 1 The diagram shown is a structural schematic of the partitioned punching and deburring mechanism provided by this utility model. The partitioned punching and deburring mechanism includes a lower die assembly 10 and an upper die assembly 20 disposed on one side of the lower die assembly 10. It is conceivable that the partitioned punching and deburring mechanism also includes other functional modules, such as a power supply module, a cylinder module for driving the upper die assembly 20 downwards, a screw module, a die frame module for aligning the upper and lower dies, etc. These are technologies known to those skilled in the art and will not be described in detail here.

[0018] Please refer to the following: Figures 2 to 4It should be noted that the deburring mechanism is used to perform deburring operations on several through holes 31 on a partition 30. Due to the functional configuration of the partition 30, the several through holes 31 on it are located in different positions. One through hole 31 is located at the center of the partition 30, at least eight through holes 31 are located on an arc with the center of the partition 30 as the center, at least four through holes 31 are located on an arc with the center of the partition 30 as the center, at least two through holes 31 are located on an arc with the center of the partition 30 as the center, and at least two through holes 31 are located on an arc of two circles with the center of the partition 30 as the center, forming a first positioning through hole 32 and a second positioning through hole 33. The spacer 30 is placed on the lower die assembly 10 and performs the deburring operation under the downward pressure of the upper die assembly 20. Then, during the lifting process of the upper die assembly 20, the air passage inside the upper die assembly 20 blows air through the through hole 31 to blow the deburred burrs out of the through hole 31. The specific operation process of the upper die assembly 20 will be described below.

[0019] The lower mold assembly 10 includes a lower mold frame 11, at least four guide posts 12 disposed at the corners of the lower mold frame 11, a lower mold 13 movably passing through the guide posts 12, at least four springs 14 respectively sleeved on the guide posts 12, and a plurality of punches 15 fixedly disposed on the lower mold frame 11.

[0020] The lower mold frame 11 is used to support the guide pillars 12 and the punches 15. Two limiting plates 16 are respectively provided at the ends of the four guide pillars 12 away from the lower mold frame 11, with each limiting plate 16 having two ends fixedly connected to the ends of the two guide pillars 12. One end of the spring 14 abuts against the lower mold frame 11, and the other end abuts against the lower mold 13. Thus, when the upper mold assembly 20 is pressed down by a driving cylinder (not shown), the lower mold 13 is moved closer to the lower mold frame 11, and the spring 14 is compressed to store power for the resetting operation of the lower mold 13. The limiting plates 16 can limit the lower mold 13 to prevent it from falling off the guide pillars 12.

[0021] The lower mold 13 has a groove 17 on the side away from the lower mold frame 11 that matches the outer convex surface of the partition 30, for placing the partition 30.

[0022] The size and position of the plurality of punches 15 are set according to the plurality of through holes 31 on the partition 30, and each punch 15 can be moved through the lower die 13, so that each punch 15 and its corresponding through hole 31 are matched, and then the punching and deburring operation is completed under the stamping of the upper die assembly 20.

[0023] The punch 15 is the same size as the through hole 31, enabling the punch 15 to deburr the through hole 31. A cylindrical portion 18 is provided at the end of the punch 15 away from the lower die holder 11, the diameter of which is smaller than the diameter of the through hole 31. Two punches 15, corresponding to the first positioning through hole 32 and the second positioning through hole 33, each have a positioning portion 19 at their ends away from the lower die holder 11, the diameter of which is the same as the diameter of the through hole 31. In the initial state of the spring 14, both the cylindrical portion 18 and the positioning portion 19 protrude from the lower die 13. Thus, when the spacer 30 is placed on the lower die 13, simply fitting the two positioning portions 19 into the first positioning through hole 32 and the second positioning through hole 33 respectively achieves precise positioning of the spacer 30, ensuring that each punch 15 corresponds to the through hole 31 on the spacer 30.

[0024] The upper mold assembly 20 includes an upper mold frame 21, an air passage plate 22 disposed on the side of the upper mold frame 21 facing the lower mold assembly 10, and an upper mold 23 disposed on the side of the air passage plate 22 facing the lower mold assembly 10.

[0025] The upper die frame 21 is connected to the output end of an external drive cylinder (not shown) to provide power for the punching operation.

[0026] The air passage plate 22 has at least two air inlets 24 on the side facing the upper die frame 21. The two air inlets 24 are respectively connected to two air pipe connectors 25 to provide air for blowing burrs. The two air pipe connectors 25 are connected to a three-way connector 26 through two air pipes. The air inlet end of the three-way connector 26 is connected to the exhaust valve of the aforementioned drive cylinder (not shown) through an air pipe. Thus, when the upper die assembly 20 completes the burr-cutting operation, during the retraction phase, the exhaust valve of the drive cylinder (not shown) exhausts air and discharges the gas into the air passage plate 22 to achieve the function of waste gas utilization and save energy.

[0027] The air passage plate 22 has at least two interconnected air passages 27 on the side away from the lower mold frame 21, and the air passages 27 are connected to the two air inlets 24.

[0028] The shape of the upper mold 23 matches the concave surface of the partition 30, and a plurality of punches 28 are provided on it, which correspond to a plurality of through holes 31 on the partition 30. The punches 28 are connected to the air passage 27.

[0029] The specific operation process of the deburring and punching mechanism is described in detail below: First, the partition 30 is placed in the groove 17 on the lower die 13, and the partition 30 is positioned by the two positioning parts 19. Then, the upper die assembly 20 performs a downward punching operation under the drive of the drive cylinder (not shown). The upper die 23 abuts against the concave surface of the partition 30 and continues to press down, so that each punch 15 completely passes through the through hole 31 on the partition 30, thereby completing the deburring operation, while the spring 14 is compressed.

[0030] A drive cylinder (not shown) drives and lifts the upper mold assembly 20, and the exhaust valve on it exhausts gas, which then passes through the three-way connector 26, the air pipe connector 25, the air inlet 24, the air passage 27, and is blown out from the punch 28. This blows away the burrs and waste material remaining in the punch 28, preventing material blockage and mold damage.

[0031] After the upper die assembly 20 is raised, the spring 14 releases its elastic potential energy, thereby lifting the lower die 13 to its initial position in preparation for the next punching operation.

[0032] Compared with the prior art, the partition punching and deburring mechanism provided by this utility model positions the partition 30 through the groove 17 and the two positioning parts 19, avoiding the need to completely fit each punch 15 into each through hole 31, which facilitates manual placement. During the pressing down of the upper die assembly, the punch 15 completely passes through the through hole 31 on the partition 30, thereby completing the deburring operation. The punching process does not require manual intervention, saving manpower. Furthermore, during the lifting process of the upper die assembly 20, the exhaust valve of the drive cylinder exhausts gas and introduces the gas into the punch hole 28, thereby blowing away the burr waste remaining in the punch hole 28, preventing material blockage and mold damage, thus achieving the function of waste gas utilization and saving energy.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
