Description

Technical Field

[0001] The utility model relates to the technical field of valve processing, in particular to a double-head flattening machine. Background Art

[0002] Pipeline accessories, the valve stem is an important part of the valve, used for transmission, connected to the actuator or handle above, and directly drives the valve core to move or rotate below to achieve the valve switch or regulation function. After cutting, the valve stem needs to use a flattening machine to grind its end flat.

[0003] Authorization announcement number CN206084014U discloses a flattening machine, which solves the problem that the current flattening machine can only process one surface, has low processing efficiency, and has a high rate of dimensional non-conformity. The key points of its technical solution are that a first flattening device and a second flattening device are arranged opposite to each other on both sides of the base, and the first flattening device and the second flattening device are provided with a cutter head that can perform rotational motion, and a fixed frame is provided in the center of the two flattening devices, and a lower die base and an upper die base are provided on the fixed frame to cooperate to form a clamping hole corresponding to the position of the cutter head, and a driving member is also provided on the fixed frame to drive the upper die base to move closer to or away from the lower die base. The motor is driven to rotate the blade, which not only realizes the simultaneous processing of the two end faces, greatly increases the processing efficiency, and the rotary processing method and the fixed method avoid dimensional deviation, and the processing accuracy is high.

[0004] The existing flattening machine has the following shortcomings: the fixed frame is fixed to the rotating plate and can rotate but cannot move, and the valve stem is fixed between the upper and lower die bases, which can only fix a single valve stem. As a result, the flattening machine can only flatten one valve stem at a time, which is inefficient. To address this problem, we propose a double-head flattening machine. Summary of the Invention

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a double-head flattening machine includes a base 1, a frame 2 and a main board 3. A reserved groove 4 is opened inside the base 1, and a reduction motor 6 is installed at one end of the reserved groove 4 through a mounting bracket. The output shaft on one side of the reduction motor 6 is connected to the reciprocating screw 7 through a connecting sleeve, and the outer side of the reciprocating screw 7 is sleeved with an internal thread slider 5. The top of the internal thread slider 5 is fixed with a frame 2 by bolts, and a cylinder 9 is installed on the top of the frame 2 through a mounting bracket. The output shaft at the bottom of the cylinder 9 is fixed with a pressure plate 10 by bolts. The main board 3 is welded at both ends of the top of the base 1, and the two ends of the top of the main board 3 are fixed with slide rails 14 by bolts. A layer plate 15 is provided on the top of the slide rail 14, and a drive motor 17 is installed on the top of the layer plate 15 through a mounting bracket. The output shaft on one side of the drive motor 17 is fixed with a grinding block 18 by bolts.

[0021] Among them, Figure 2 As shown, the end of the reciprocating screw 7 away from the reduction motor 6 is fixed to the inside of the reserved groove 4 through a bearing, and a first auxiliary rod 8 is fixed to the bottom of the reserved groove 4 by bolts. The first auxiliary rod 8 passes through the internal thread slider 5. The first auxiliary rod 8 can improve its structural stability without affecting the movement of the internal thread slider 5.

[0022] Among them, Figure 3 As shown, the pressure plate 10 is located inside the frame 2, and the top two ends of the pressure plate 10 are connected to the second auxiliary rod 13 through a threaded groove. The second auxiliary rod 13 passes through the frame 2. The setting of the second auxiliary rod 13 can improve its structural stability without affecting the up and down movement of the pressure plate 10.

[0023] Among them, Figure 3As shown, lower card slots 11 are equidistantly provided at the bottom of the frame 2, and upper card slots 12 are equidistantly provided at the bottom of the pressure plate 10. The arrangement of the lower card slots 11 and the upper card slots 12 facilitates the engagement and fixation of multiple valve stems.

[0024] Among them, such as Figure 4 As shown, the two ends of the bottom of the layer 15 are fixed with sliders 16 by bolts, and the sliders 16 are slidably connected to the inside of the slide rail 14. The two ends of the top of the layer 15 are penetrated by threaded grooves and provided with fixing bolts 19. The setting of the slide rail 14 and the slider 16 facilitates the movement of the layer 15.

[0025] It should be noted that the present invention is a double-head flattening machine. When working, personnel use a power cord to connect the device to an external power supply, use an air pipe to connect an external air supply device to the cylinder 9, place multiple valve stems in the lower card slot 11 at the bottom of the frame 2, open the cylinder 9 to push the pressure plate 10 downward, and clamp and fix the valve stem through multiple upper card slots 12. Personnel turn on the drive motor 17 to drive the grinding block 18 to rotate at high speed, turn on the reduction motor 6 to drive the reciprocating screw rod 7 to rotate, and the reciprocating screw rod 7 rotates to push the internal thread slide The block 5 moves back and forth, and the internal threaded slider 5 moves to drive the frame 2 and the multiple valve stems fixed inside it to move back and forth. When the valve stem moves between the main boards 3, the high-speed rotating grinding block 18 grinds its end until the end is polished flat. The layer 15 is fixed to the top of the main board 3 through the slider 16 and the slide rail 14, and can slide to facilitate adjusting the distance between the fixing bolts 19 according to the length of the valve stem. Tightening the fixing bolts 19 can make its bottom end press against the main board 3, so that the moved layer 15 can be fixed.
