Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture equipment processing devices, and in particular relates to a cutting device for cutting off a special-shaped material opening in a feeding cover in aquaculture equipment. Background Art

[0002] In egg-laying poultry breeding equipment, when breeding in large quantities, a standard feeding device is required to feed the silo or storage device. In such storage devices, a special-shaped feed port is usually provided, and such special-shaped feed port is usually designed to be circular, square or polygonal in structure. For such special-shaped feed ports, the current manufacturing process is to realize the overall molding of the feed cover by means of injection molding. During molding, multiple flow channels are set in the special-shaped feed port area, and the material is evenly guided to the special-shaped feed port area through multiple flow channels. On the one hand, the perfect molding of the special-shaped feed port is realized, and on the other hand, the number of flow channels in the rest of the feed cover area is reduced, and the number of receiving positions on the feed cover is reduced, so as to avoid subsequent grinding and finishing on a large scale, reduce the product manufacturing process, and reduce the manufacturing cost.

[0003] However, the technical problem encountered in the above production process is that in the subsequent trimming of the special-shaped material gate, cutting equipment must be used to remove the gate protrusions formed after the solidification of multiple runners. However, there is currently no unified equipment available, and only manual cutting can be used. This method is inefficient and cannot guarantee a flush incision, resulting in uneven product quality.

[0004] In view of the shortcomings of the existing technology, the technical problem that technical personnel in this field need to solve is: to design a special-shaped material gate cutting device, which is required to be able to uniformly cut off the gate protrusions in the special-shaped material gate area, effectively ensure the uniformity of the incision while improving the efficiency of gate protrusion trimming, and improve product quality.

[0025] As shown in the accompanying drawings, a device for cutting off a special-shaped material opening includes a support frame 1, a lower fixing platform 11 is arranged in the middle of the support frame 1, a bottom fixing plate 13 is arranged on the lower fixing platform 11, and the lower mold 2 is fixed by the bottom fixing plate 13.

[0026] In this embodiment, Figure 1 , 3 As shown, the lower die 2 is provided with a support platform 21, and the shape of the support platform 21 matches the special-shaped material port area on the feeding cover 7, and the two can be seamlessly overlapped when the feeding cover is placed on the support platform 21. The utility model is provided with a plurality of vertical punching holes 23 at the center of the support platform 21, and each vertical punching hole 23 is provided with a bottom protrusion 22 on both sides, and the upper end surface of the vertical punching hole 23 is used to support the gate protrusion 8. The vertical punching holes 23 described here match the shape of the punching knife upper die, and during punching, the upper die 4 and the lower die 2 form a vertical plug-in matching structure.

[0027] The utility model is provided with a top fixing plate 12 on the top of the support frame 1, on which a guide rod 5 is slidably provided through a guide sleeve 51, the bottom of the guide rod 5 is fixed on the upper template 3, and the bottom of the upper template 3 is fixed with an upper mold 4.

[0028] A buffer connecting rod assembly 6 is arranged between the upper template 3 and the top fixed plate 12. The buffer connecting rod assembly 6 is symmetrically arranged on the left and right, and is also symmetrically arranged front and back with the top driving plate 61 as the center. The specific structure of the utility model is as follows: a detailed description is given by taking the structure of one side of the left and right sides as an example. As shown in the figure, it includes a top driving plate 61, an upper connecting rod 63, a middle connecting rod 62 and a lower connecting rod 64. The upper end of the upper connecting rod 63 is hinged to the upper hinged block 16 below the top fixed plate 12, the lower end of the lower connecting rod 63 is hinged to the lower hinged block 31 above the upper template, the upper end of the middle connecting rod 62 is hinged to the top driving plate 61, and the lower end of the upper connecting rod 63, the lower end of the middle connecting rod 62 and the upper end of the lower connecting rod 64 are hinged through a middle hinge shaft 65.

[0029] On the basis of the above structural arrangement, the buffer link assembly 6 is also arranged symmetrically in the front and rear directions, the upper link 63, the middle link 62 and the lower link 63 are arranged symmetrically in the front and rear directions, and the top driving plate 61 is located between the two groups of middle links 62 arranged in the front and rear directions. The middle hinge shaft 65 is a through shaft, which is used to realize the coaxial linkage of the buffer link assembly 6 that is symmetrical in the front and rear directions.

[0030] After the above structure is set, the utility model fixes the drive cylinder 9 on the upper part of the top fixing plate 12, and the force-applying end of the drive cylinder 9 is fixed on the top driving plate 61, combined with Figure 3 and Figure 4 As shown, the bottom surface of the top fixing plate 12 is provided with an upper recessed groove 14 , and when the buffer link assembly 6 is folded and contracted, the upper recessed groove 14 is used to store the top driving plate 61 .

[0031] In the non-stamping state, such as Figure 3 As shown, the drive cylinder 9 contracts, the top fixing plate 12 is stored in the upper sink 14, and the top drive plate 61 pulls the middle connecting rod 62 to lift and contract toward the middle, and the middle connecting rod 62 drives the upper connecting rod 63 and the lower connecting rod 63 to tilt and contract. This tilting and contraction folds the entire buffer connecting rod assembly 6 into a compact block structure, and the upper mold 3 and the upper mold 4 are driven by the lower connecting rod 63 to rise synchronously and separate from the lower mold 2. Figure 3 The structural state shown is the non-stamped state.

[0032] In the stamping state, Figure 4 As shown, the drive cylinder 9 is stretched by force, the top fixed plate 12 is stressed and separated from the upper sink 14, and the top drive plate 61 pushes the middle connecting rod 62 to move downward. The middle connecting rod 62 drives the upper connecting rod 63 and the lower connecting rod 63 to stretch. This stretching supports the entire buffer connecting rod assembly 6 to form an H-shaped supporting structure. The upper mold plate 3 and the upper mold 4 are driven to descend synchronously through the lower connecting rod 63 to close the mold with the lower mold 2, and the gate protrusion 8 on the loading cover 7 placed on the support platform 21 of the lower mold 2 is punched and cut off.

[0033] The purpose of setting the above buffer link assembly 6 is to achieve synchronous stamping of multiple stamping points, and this stamping is a progressive method, which can achieve the transformation of the stamping force from small to large while ensuring the stamping strength, which can effectively improve the stamping effect and ensure the smoothness of the punching cut.

[0034] On the basis of the above driving principle, in order to further improve the stamping accuracy, the utility model makes a series of structural changes to the lower die 2 and the upper die 4. The purpose of the improvement is to achieve the blanking after the gate protrusion 8 is fixed, to ensure that the stamped part does not shake during blanking, to ensure the neat blanking of the edge, and to make the edge of the special-shaped material port on the upper cover 7 neat. The specific changes are as follows:

[0035] A plurality of radial branches 41 are arranged on the bottom surface of the upper mold 4, and a groove 42 is commonly arranged in the plurality of radial branches 41 and the middle area. A punch 43 is arranged at the end of the radial branch 41 toward the bottom, and the punch here is integrated with the radial branch 41. A technician in this field may also design this as a split type, and no structural limitation is made here.

[0036] like Figure 1 As shown, the lower die 2 is provided with a support platform 21, and a plurality of vertical punching holes 23 are provided at the center of the support platform 21. Bottom protrusions 22 are provided on the left and right sides of each vertical punching hole 23, and the upper end surface of the vertical punching hole 23 is used to support the gate protrusion 8. The radial branch 41 provided at the bottom of the upper die 4 is plugged and matched with the vertical punching hole 23.

[0037] When the gate protrusion 8 is punched, the plurality of radial branches 41 and the groove 42 provided in the middle area can cover and press the gate protrusion 8 downward to prevent it from being displaced and vibrated instantaneously during punching.

[0038] Further, such as Figure 2 As shown, a plurality of feeding cover support rods 31 are also provided on the bottom surface of the upper mold 4, and the height of the feeding cover support rods 31 is lower than that of the upper mold 4. The feeding cover support rods 31 are made of rubber or plastic. When the stamping action is realized, when the upper mold 4 is pressed on the feeding cover 7, the feeding cover support rods 31 with a flexible structure are used to achieve final compression, and under the condition of ensuring compression, the feeding cover support rods 31 are prevented from causing impact damage to the feeding cover 7.

[0039] In summary, the utility model, through the above structural setting, can drive the upper template 3 to move up and down on the top fixed plate 12 through the driving cylinder 9 when punching the gate protrusion. During the downward movement, the buffer connecting rod assembly 6 is used to achieve punching buffering. The upper mold 4 squeezes the feed cover 7 in a buffering state and punches the special-shaped material port. Synchronous shaping can also be achieved during punching. The utility model has stable operation, can effectively achieve synchronous punching of various points of the gate protrusion 8, effectively protects the feed cover 7 from being damaged by strong punching force during the punching process, and can ensure the punching quality and improve the product quality.
