Description

Technical Field

[0001] The utility model belongs to the technical field of butterfly valve processing, and more specifically, particularly relates to a punching device for butterfly valve processing. Background Art

[0002] A butterfly valve is a valve that uses a circular butterfly plate as an opening and closing member and rotates with the valve stem to open, close and adjust the flow of a fluid channel. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It is the best device for regulating flow and cutting off fluid in food, medicine, fire protection, petrochemical, industrial environment, high-rise buildings and pipelines. The installation between the valve and the pipeline is mostly connected by flange connection. The flange is an important component for connecting various pipelines and valves, usually connected to the pipe end. When the flange is produced, a through hole needs to be opened on the flange using a punching device. Therefore, a punching device for flange butterfly valve processing is required.

The utility model sets a limit adjustment screw on the punching placement table, and a fixed pressure wheel is set on the limit adjustment screw. After the flange body is placed on the punching placement table, the fixed pressure wheel can be rotated to squeeze the fixed pressure wheel on the flange body, so that the flange body can be quickly limited and fixed, and the flange body can be prevented from vibrating during punching.

[0004] The punching device in the above patent still has the following shortcomings:

[0005] Although the punching device in the above patent can fix the workpiece well during use, it needs to be rotated and moved when punching, so that the punching position needs to be repositioned each time a hole is punched, which increases the construction process and is not conducive to improving processing efficiency.

[0024] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0025] Embodiment 1:

[0026] like Figures 1 to 6 As shown:

[0027] The present embodiment provides a punching device for butterfly valve processing, comprising: a platform 1; the platform 1 adopts a rectangular plate structure, and a through circular through groove structure is opened on the top of the platform 1, and a through screw hole structure is opened on the front top of the platform 1; a fixing plate 2 with a rectangular plate structure is fixedly provided at the bottom of the platform 1; two groups of cylindrical fixing rods 102 are fixedly provided on the front side of the platform 1, and springs are sleeved on the outer sides of the fixing rods 102; sliding plates 104 with a rectangular plate structure are slidably provided on the outer sides of the two groups of fixing rods 102; a pedal 105 is fixedly provided on the right bottom of the sliding plate 104; a rack 106 is fixedly provided on the left bottom of the sliding plate 104.

[0028] The front side of the platform 1 is rotatably connected with a gear 107 , and the gear 107 is meshingly connected with the rack 106 ; the rear side of the gear 107 is fixedly connected with an external ratchet 108 .

[0029] Among them, a processing table 201 with a circular plate-shaped structure is rotatably arranged on the top of the fixed plate 2, and the outer wall of the processing table 201 is fitted with the inner wall of the rectangular through groove at the top of the platform 1, and through-type screw hole structures are opened on both sides of the top of the processing table 201; a group of first screw rods 202 are rotatably arranged in the screw holes on both sides of the top of the processing table 201 through threaded cooperation; a clamping plate 203 with a circular plate-shaped structure is fixedly arranged on the inner end of the first screw rod 202.

[0030] Among them, a worm wheel 204 is fixedly arranged on the outer side of the bottom of the rotating shaft of the processing table 201; a worm 205 is rotatably arranged on the bottom of the fixed plate 2, and the worm 205 is meshingly connected with the worm wheel 204; an inner ratchet 206 is fixedly arranged on the outer side of the front end of the worm 205, and the inner ratchet 206 is arranged on the inner side of the outer ratchet 108.

[0031] The specific usage and function of this embodiment are as follows:

[0032] During processing, the workpiece to be processed is placed on the top of the processing table 201, and the processing area of ​​the workpiece is adjusted to the bottom of the punching device 101. Then, the two sets of first screws 202 are rotated and the workpiece is fixedly clamped on the processing table 201 through the two sets of clamping plates 203. Then, the punching device 101 can be started to punch holes in the fixed workpiece. After the current hole position is punched, the staff can step on the pedal 105 to drive the sliding plate 104 to slide downward along the two sets of fixed rods 102, so that the sliding plate 104 slides downward to the position in contact with the top of the limit screw 103 and then stops, and at the same time drives the rack 106 to move downward, and drives the gear 107 to rotate through the rack 106, and the gear 107 synchronously drives the outer ratchet 108 to rotate, and the inner ratchet 206 and the worm 205 are synchronously driven to rotate through the engagement of the outer ratchet 108 and the inner ratchet 206. The worm 205 drives the worm wheel 204 and the processing table 201 to rotate synchronously above the fixed plate 2, so that the workpiece above the processing table 201 rotates a certain distance, so that the processing area of ​​the next hole position of the workpiece rotates to the bottom of the punching device 101, and then the next hole position can be processed. Then the sliding plate 104, the rack 106 and the pedal 105 slide upward and reset under the action of the springs on the outside of the two sets of fixed rods 102. In the process of driving the gear 107 to rotate in the opposite direction, since the outer ratchet 108 and the inner ratchet 206 cannot engage when rotating in the opposite direction, the worm 205 and the processing table 201 will not be driven to rotate. During the entire processing process, the processing personnel only need to step on the pedal 105 to complete the replacement of the processing hole position of the workpiece without re-positioning, which greatly reduces the work participation of the staff, is conducive to improving work efficiency and reducing labor costs.

[0033] Embodiment 2:

[0035] A punching device 101 is fixedly provided on the top rear side of the platform 1 , and the punching device 101 is a lifting structure; a limiting screw 103 is rotatably provided in the screw hole on the front side of the platform 1 .

[0036] The specific usage and function of this embodiment are as follows:

[0037] In the utility model, when it is necessary to adjust the degree of rotation of the processing table 201, the limit screw 103 can be rotated to make the limit screw 103 rise or fall on the front side of the platform 1, so that the sliding distance of the sliding plate 104 can be adjusted, and then the sliding distance of the rack 106 can be adjusted, so as to achieve the purpose of adjusting the rotation angle of the processing table 201 and the workpiece thereon. It can be adjusted according to different production needs, which greatly improves the practicality of the device and is more worthy of popularization and use.
