Technical Field

[0001] The present application relates to the technical field of tap heat treatment cleaning devices, and in particular to a tap heat treatment cleaning device. Background Art

[0002] Heat treatment is to heat the metal material to a certain temperature, keep it at that temperature for a certain period of time, and then cool it down to room temperature or lower at a certain rate, so as to improve the material structure and obtain excellent performance.

[0003] In the technical field of tap heat treatment, for example, a utility model patent with authorization announcement number CN214032623U discloses a heat treatment device for tap drill bits of surgical instruments with a large aspect ratio, which allows the tap drill bits to be placed vertically through a support frame, thereby avoiding extrusion and collision that are prone to occur in the original stacking method; at least one row of hanging rods is provided on the support frame, and a clip is provided on the hanging rod, and one end of the tap drill bit is clamped with the clip, so that the tap drill bit is vertically suspended inside the furnace chamber, which can keep the tap drill bits from contacting each other and avoid extrusion and collision.

[0004] During the heat treatment process, when the liquid comes into contact with the high-temperature tap, quenching slag will adhere to the outer surface of the workpiece, so the workpiece needs to be cleaned multiple times afterwards. The slag may adhere to the outer surface of the workpiece after cooling, which is not convenient for subsequent cleaning. Summary of the invention

[0005] In order to clean a portion of the debris earlier after the heat treatment, the present application provides a cleaning device for the heat treatment of a tap.

[0006] The present application provides a cleaning device for heat treatment of taps, which adopts the following technical solution: a cleaning device for heat treatment of taps, comprising a treatment box, a plurality of fixing frames are arranged on the inner edge of the treatment box, the fixing frames are used to fix workpieces, a movable rod is movably arranged on the upper side of the treatment box, a fixed tube is rotatably arranged on the fixing frame, a striking piece for striking the fixed tube is arranged on the movable rod, so that the fixed tube rotates circumferentially, and the fixed tube has a rebound rotation stroke in the circumferential direction.

[0007] By adopting the above technical solution, the workpiece is fixed on the fixed tube. After the heat treatment is completed, the movable rod is allowed to slide. During the sliding process, the striking piece will move accordingly. The striking piece will hit the fixed tubes on the same column in turn, so that the fixed tubes rotate, which will form circumferential shaking. Without affecting each other, preliminary cleaning of a single workpiece can be formed, thereby improving the cleaning efficiency.

[0008] Preferably, a matching frame located on one side of the movable rod is provided on the upper side of the processing box, and the matching frame has an obstruction block for resisting and causing the striking piece to bend and deform, and the fixed tube has an impact block for colliding with the striking piece, and when the striking piece is separated from the obstruction block, the striking piece hits the impact block to cause the fixed tube to rotate.

[0009] By adopting the above technical solution, the striking piece will be deformed when it moves to the obstruction block, and in the process after the deformation, its free end will form a striking effect, thereby prompting the fixed tube to rotate.

[0010] Preferably, the obstruction block has avoidance grooves on both sides, and the extension length of the avoidance grooves is sufficient for the striking piece to return to its original state in the avoidance grooves, and the free end of the striking piece moves circumferentially and strikes the collision block.

[0011] Preferably, there is a space between the matching frame and the movable rod for the striking piece to deform.

[0012] Preferably, there are push rods on the matching frame and located at both ends of the blocking block, the push rods are used to block the middle of the striking piece and prevent the striking piece from touching the collision block again, and the diameter of the push rods is not greater than one third of the length of the striking piece.

[0013] By adopting the above technical solution, during the rotation of the striking piece, only the end portion will have a striking effect on the collision block, and after the collision, the striking piece will fit on the support rod, and there will be no other shaking that affects the fixed tube.

[0016] By adopting the above technical solution, in the process of being blocked by the resistance rod, due to the thickness, the second section is easily deformed, so that the third section hits the collision block, and at the same angular velocity, the movement radius becomes smaller, which can enable the collision block to obtain a larger initial velocity and form a shock effect.

[0017] By adopting the above technical solution, the first section has a metal sheet connected to the movable rod inside, and the length of the metal sheet is greater than the distance between the movable rod and the matching frame.

[0018] Preferably, the movable rod reciprocates back and forth along the direction of the fixed frame; and the initial position of the collision block is located in the middle position of the obstruction block.

[0019] By adopting the above technical solution, during the back-and-forth movement, the fixed tube will perform opposite movements in the circumferential direction and can form a back-and-forth rocking effect.

[0020] Preferably, the end of the impact block away from the striking piece has a counterweight block, the part of the impact block inserted in the fixed tube is a sliding rod, a counterweight spring is sleeved on the exposed part of the sliding rod, and the two ends of the counterweight spring are respectively connected to the counterweight block and the fixed tube; when the counterweight spring is in an initial state, the distance between the counterweight block and the central axis of the fixed tube is greater than the distance between the impact block and the central axis of the fixed tube.

The movable rod slides, and during the sliding process, the striking piece will move accordingly. The striking piece will hit the fixed tubes on the same row in turn, so that the fixed tubes rotate, which will form a circumferential shake. Under the condition of not affecting each other, it can form a preliminary cleaning of a single workpiece and improve the cleaning efficiency; 2. When the striking piece moves to the obstruction block, it will be deformed. After the deformation, its free end will have a striking effect, thereby causing the fixed tube to rotate and form a back-and-forth shaking effect; 3. During the rotation of the striking piece, only the end portion will have a striking effect on the collision block, and after the collision, the striking piece will fit on the support rod, and there will be no other shaking to affect the fixed tube.

DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] Example 1: This application example discloses a cleaning device for heat treatment of taps, referring to Figure 1 , Figure 2 , including a processing box 100 , a plurality of fixing racks 110 are arranged on the inner edge of the processing box 100 , the fixing racks 110 are used to fix the workpieces, and the fixing racks 110 are arranged in an array on the upper side of the processing box 100 .

[0026] A fixed tube 111 is rotatably provided on the fixed frame 110, and the lower end of the fixed tube 111 is used to fix the taps, so that each tap can remain independent and will not be squeezed or collided with each other during the processing. A movable rod 120 is slidably provided on the upper side of the processing box 100, and the same movable rod 120 corresponds to a row of fixed tubes 111. The movable rod 120 is provided with a striking piece 112 for striking the fixed tube 111, so that the fixed tube 111 rotates circumferentially, and the fixed tube 111 has a rebound rotation stroke in the circumferential direction.

[0027] Specifically, refer to Figure 2 , Figure 3 The striking piece 112 includes a first section 113, a second section 114, and a third section 115. The striking piece 112 is made of silicone material as a whole and is deformable. The first section 113 is fixedly connected to the movable rod 120. The first section 113 has a metal sheet body 116 connected to the movable rod 120. The outside of the first section 113 is wrapped around the metal sheet body 116. The thickness of the second section 114 is less than that of the first section 113 and the third section 115.

[0028] Reference Figure 2 , Figure 4The fixed tube 111 has a collision block 130 for colliding with the striking sheet 112, and a return spring 131 is connected between the fixed tube 111 and the fixed frame 110. A matching frame 140 is provided on the upper side of the processing box 100 and is located on one side of the movable rod 120. The matching frame 140 has an obstruction block 141 for resisting and bending the striking sheet 112. There is a space between the matching frame 140 and the movable rod 120 for the striking sheet 112 to bend and deform. There are avoidance grooves 142 on both sides of the obstruction block 141. The extension length of the avoidance groove 142 allows the striking sheet 112 to return to its original state in the avoidance groove 142, and the free end of the striking sheet 112 moves circumferentially and hits the collision block 130.

[0029] Specifically, the initial position of the impact block 130 is located in the middle of the blocking block 141, and return springs 131 are provided on both sides of the impact block 130. Under the action of the two return springs 131, the position of the fixed tube 111 will keep the impact block 130 in the middle of the blocking block 141 in the final state.

[0030] During the movement of the movable rod 120, the striking piece 112 will first be squeezed by the obstruction block 141, thereby forming a bent state. As the movable rod 120 continues to move, the striking piece 112 will move to the avoidance groove 142. When the striking piece 112 breaks away from the obstruction block 141, the metal sheet body 116 in the striking piece 112 will return to its original state, causing the striking piece 112 to swing as a whole, hitting the collision block 130 to cause the fixed tube 111 to rotate.

[0031] Reference Figure 5 , Figure 6 In order to prevent the striking piece 112 from affecting the fixed pipe 111 that has already started to rotate after the collision, in this embodiment, both ends of the obstruction block 141 have abutment rods 143. In this embodiment, both ends of the avoidance groove 142 are provided with abutment rods 143. During the reciprocating movement of the movable rod 120, it will be respectively attached to the abutment rods 143 on both sides. The abutment rods 143 are used to block the middle part of the striking piece 112 and prevent the striking piece 112 from hitting the collision block 130 again. The diameter of the abutment rod 143 is not greater than one-third of the length of the striking piece 112. Specifically, the second section 114 is used to abut against the abutment rod 143, so that the third section 115 rotates again and hits the collision block 130.

[0032] In addition, the three-stage striking piece 112 can increase the initial rotation amount, and the original rotation speed of the metal sheet 116 will be accelerated, so that the striking block 130 can increase the initial rotation speed and rotation angle of the fixed tube 111, and the circumferential rotation can form a better vibration effect to make the debris fall. It is worth noting that the length of the metal sheet 116 in this embodiment is greater than the distance between the movable rod 120 and the matching frame 140, so that when bent, the metal sheet 116 always has a good tendency to return to its original state.

[0033] The movable rod 120 can be driven by a motor, a gear or a cylinder, as long as it forms a reciprocating motion. Under the bidirectional motion, the fixed tube 111 will produce a bidirectional rotation and swing and rotate through two return springs 131.

[0034] Embodiment 2: The difference from Embodiment 1 is that, referring to Figure 7 , Figure 8 The impact block 130 is passed through and slidably connected in the fixed tube 111. The end of the impact block 130 away from the striking plate 112 is provided with a counterweight block 151. The part of the impact block 130 passing through the fixed tube 111 is a sliding rod 150. A counterweight spring 152 is sleeved on the exposed part of the sliding rod 150. One end of the counterweight spring 152 is fixed on the counterweight block 151, and the other end is fixed to the outer wall of the fixed tube 111.

[0035] It is worth noting that when the counterweight spring 152 is in the initial state, the distance between the counterweight block 151 and the central axis of the fixed tube 111 is greater than the distance between the collision block 130 and the central axis of the fixed tube 111. When the striking piece 112 collides with the collision block 130, the fixed tube 111 begins to rotate in a circumferential direction. Due to the existence of the counterweight block 151 and the setting of the distance, the counterweight block 151 will drive the sliding rod 150 to slide, so that the collision block 130 retreats toward the central axis of the fixed tube 111. At the same time, the counterweight spring 152 will deform, which can prevent the striking piece 112 from interfering with the collision block 130. At the same time, after the movement is completed, the counterweight spring 152 will reset, so that the collision block 130 is reset to its original position.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
