Description

Technical Field

[0001] This utility model relates to the field of hardware processing equipment technology, and more specifically to a continuous feeding structure for a four-stage quick-punching die for punching mesh holes on the lower front frame of a television. Background Technology

[0002] The existing lower front frame assembly of TVs requires the processing of mesh holes. However, due to the different lengths and sizes of various frame mesh covers, traditional CNC milling or laser cutting is costly.

[0003] Therefore, punching is performed between the upper and lower dies. However, this structure is generally suitable for coil processing, but coils have poor strength and poor results. To improve their strength, profile processing is required. Since profile raw materials are straight materials, they cannot be made into coils. This means that manual feeding and gradual pushing of the material are necessary for punching. The manual pushing efficiency is low, and the moving distance needs to be manually controlled, which is difficult and can easily lead to inaccurate punching positions. Utility Model Content

[0025] A waist-shaped moving channel 31 is formed in the middle between the front and rear corresponding conveying channels of each conveying plate 30. A middle waist-shaped channel 32 is formed on the top surface of the conveying plate between the two corresponding waist-shaped moving channels 31 on the left and right. The lifting block 40 is inserted into the middle waist-shaped channel 32. The top of the lifting block 40 is fixed with a left and right extending pressing block 41. The bottom end of the pressing block 41 is above the corresponding waist-shaped moving channel 31. A bottom fixing plate 42 is provided below the waist-shaped moving channel 31. A clamping cylinder 43 is fixed on the top surface of the bottom fixing plate 42. The lifting block 40 is fixed on the top of the push rod of the clamping cylinder 43. Two guide blocks are fixed in the middle of the top surface of the clamping cylinder 43. The front and rear side walls of the lifting block 40 are close to the opposite walls of the two corresponding guide blocks. The guide blocks are inserted into the middle waist-shaped channel 32. The left and right side walls of the guide blocks are close to the inner side walls of the middle waist-shaped channel 32.

[0026] The two bottom fixing plates 42 fix the same front-to-back extending guide rail 45;

[0027] A linear module 50 extending forward and backward is fixed in the middle of the bottom surface of the rear conveyor plate 30. A horizontal connecting plate is fixed in the bottom surface of the moving block of the linear module 50. The front part of the horizontal connecting plate is fixed on the bottom fixing plate 42 at the rear.

[0028] Furthermore, a bottom clamping block 46 is inserted into the waist-shaped movable through groove 31 directly below the left and right parts of the clamping block 41. The bottom surface of the bottom clamping block 46 is fixed to the top surface of the corresponding clamping cylinder 43. The top surface of the bottom clamping block 46 is formed with a toothed surface, and the bottom surfaces of the left and right parts of the clamping block 41 are formed with toothed surfaces, which correspond to each other.

[0029] Two limit proximity switches 1 are fixed on the bottom surface of the conveyor plate 30 on the left side of the linear module 50. A sensing plate 2 is fixed on the top surface of the side of the corresponding moving block. The sensing plate 2 corresponds to the sensing end on the inner side of the two limit proximity switches 1.

[0030] The bottom mold fixing plate 12 has blanking through holes 121 formed on the left and right sides of its middle section, which communicate with the downwardly extending receiving cavity formed on the top surface of the waste receiving shell 20 below. The bottom mold fixing plate 13 has upper mounting through grooves formed on the left and right sides of its middle section. Two guide sleeves 3 are fixed on the top surface of the bottom mold fixing plate 12. A lower module 14 is fixed on the top surface of the guide sleeves 3. The blanking through holes of the lower module 14 communicate with the guide sleeves 3. 3 is connected to the corresponding blanking through hole 121. Side guide blocks 4 are fixed on the top surface of the bottom mold fixing plate 12 on both sides of the guide sleeve 3. The guide sleeve 3 and the lower module 14 are inserted into the corresponding upper mounting through groove. The top surface of the lower module 14 is flush with the top surface of the lower mold fixing plate 13. The side wall of the lower module 14 is close to the inner side wall of the upper mounting through groove. The tops of the two side guide blocks 4 extend out of the top surface of the lower mold fixing plate 13 and are located on the left and right sides of the corresponding lower module 14.

[0031] The guide rail 45 is inserted into the through hole in the middle of the two support blocks 11 and the through hole formed on the front and rear side plates of the waste receiving housing 20. The guide rail 45 is close to the inner wall of the through hole. The bottom surface of the two conveying plates 30 is fixed with an end guide slider 5 at one end that is close to each other. The guide rail 45 is inserted into the groove of the guide slider 5 and cooperates with it.

[0032] The waste receiving housing 20 has an air intake connector 21 connected to its left or right side plate. The air intake connector 21 is connected to the air inlet of the waste collection box 60 via a connecting pipe. The top of the waste collection box 60 is connected to an exhaust connector 61, and the other end of the exhaust connector 61 is connected to the air inlet of the blower 62.

[0033] The lower module 14 has multiple punched through holes formed in the middle. An upper die assembly 80 is provided above the lower die fixing plate 13. The bottom ends of multiple punches of the upper die assembly 80 face the corresponding punched through holes. The upper die assembly 80 is installed in the upper stamping equipment, which is consistent with the existing equipment structure and will not be described in detail.

[0034] In this embodiment, all cylinders are connected to the control valve of the pneumatic system via connecting pipes. The pneumatic system is a conventional structure and will not be described in detail here. At the same time, all electrical components in this embodiment are electrically connected to the control host via electrical connection lines and are controlled by the control host. This is a conventional structure and will not be described in detail here.

[0035] In this embodiment, two lower front frame assemblies 100 to be processed are placed in corresponding conveying channels. Then, the push rods of the two clamping cylinders 43 retract, so that the corresponding position of the rear of the lower front frame assembly 100 is clamped between the toothed surface of the bottom clamping block 46 and the toothed surface of the left or right part of the pressing block 41 (at this time, the front part of the lower front frame assembly 100 has not yet passed through the lower module 14). Then, the linear module 50 runs, causing the moving block to move forward. The sensing plate 2 of the moving block is first sensed by the sensing end on the inner side of the limit proximity switch 1 behind it. After it moves forward, The sensor plate 2 is moved into position when it is sensed by the sensing end inside the limit proximity switch 1. At this time, the front end of the lower front frame assembly 100 moves forward and is above the top surface of the lower module 14. Then, the upper mold assembly 80 descends, causing the punch to punch a hole in the lower front frame assembly 100. Its lower end enters the corresponding punched through hole in the lower module 14, and the waste material enters the waste receiving housing 20. Since the waste material is light and small, it can be sucked into the waste collection box 60 by the operation of the blower 62 for collection, which is very convenient.

[0036] After processing, the upper mold assembly 80 is lifted, the push rod of the rear clamping cylinder 43 pushes, and then the linear module 50 runs, causing the moving block to move backward until the rear limit proximity switch 1 senses the sensing plate 2, indicating that it has moved into place. Then, the push rod of the clamping cylinder 43 retracts to clamp and fix the lower front frame assembly 100. Then, the linear module 50 runs to move the lower front frame assembly 100 forward. The process is the same as before, and drilling can be performed step by step.

[0037] The front end of the lower front frame assembly 100 is located at the front clamping block 41. The push rods of the two clamping cylinders 43 can be retracted to clamp and fix the lower front frame assembly 100 and move it forward, so that it can be processed one by one. The processing effect is good and the efficiency is high.

[0038] In this embodiment, two lower front frame assemblies 100 can be processed at one time. At the same time, the lower front frame assembly 100 needs to be cut in half at the end to make a lower front frame for television. Therefore, it is equivalent to processing four lower front frames at one time, which is very efficient.

[0039] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
