Description

Technical Field

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

[0002] Heat treatment is to heat metal materials to a certain temperature, hold for a certain time, and then cool to normal 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, the utility model patent with the authorization announcement number CN214032623U discloses a heat treatment device for a tap drill bit with a large length-diameter ratio for surgical instruments. It vertically places the tap drill bit through a support frame, which can avoid the extrusion and collision that easily occur in the original stacking method; at least one row of hanging rods is arranged on the support frame, and clips are arranged on the hanging rods. One end of the tap drill bit is clamped by the clips, so that the tap drill bit is vertically suspended inside the furnace cavity, 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 contacts the high-temperature tap, quenching slag will be generated and adhered to the outer surface of the workpiece. Therefore, the workpiece needs to be cleaned multiple times later. There is a possibility that the slag adheres to the outer surface of the workpiece after cooling in the later stage, which is not convenient for subsequent cleaning. Summary of the Invention

[0005] In order to clean a part of the slag earlier after heat treatment, this application provides a cleaning device for tap heat treatment.

[0006] A cleaning device for tap heat treatment provided by this application adopts the following technical solution: A cleaning device for tap heat treatment includes a treatment box. A number of fixing frames are arranged along the inside of the treatment box, and the fixing frames are used to fix the workpiece. An activity 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 activity rod, so that the fixed tube rotates circumferentially, and the fixed tube has a resilient 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 activity rod is made to slide. During the sliding process, the striking piece will move accordingly. The striking piece will sequentially strike the fixed tubes in the same column, so that the fixed tubes rotate, and a circumferential jitter will be formed. Without affecting each other, a preliminary cleaning of a single workpiece can be formed, 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.

[0014] Preferably, a return spring is connected between the fixing tube and the fixing frame.

[0015] Preferably, the striking piece includes a first section, a second section, and a third section, the first section is used to be connected to the matching frame, the second section is thinner than the first section and the third section, and the second section is used to abut against the lower side of the support rod so that the third section strikes the impact block.

[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 shaking effect.

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

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The movable rod slides. During the sliding process, the striking piece will move accordingly. The striking piece will sequentially strike the fixed tubes in the same column, so that the fixed tubes rotate, forming circumferential jitter. Without mutual influence, it can form a preliminary cleaning of a single workpiece and improve the cleaning efficiency;

[0023] 2. When the striking piece moves to the blocking block, it will deform. During the process after deformation, its free end forms a striking effect, thus promoting the rotation of the fixed tube and being able to form a back-and-forth shaking effect;

[0024] 3. During the rotation of the striking piece, only the end part will strike the striker, and after the impact, the striking piece will fit on the abutting rod, and there will be no other shaking affecting the fixed tube. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] Embodiment 1: An embodiment of the present application discloses a cleaning device for tap heat treatment. Referring to Figure 1 、 Figure 2 , it includes a processing box 100. A plurality of fixing frames 110 are arranged along the inside of the processing box 100. The fixing frames 110 are used to fix workpieces, and the fixing frames 110 are arranged in an array on the upper side of the processing box 100.

[0036] A fixing tube 111 is rotatably arranged on the fixing frame 110. The lower end of the fixing tube 111 is used to fix the tap, so that each tap can be kept independent and will not be affected by mutual extrusion and collision during the processing. A movable rod 120 is slidably arranged on the upper side of the processing box 100. The same movable rod 120 corresponds to a column of fixing tubes 111. A striking piece 112 for striking the fixing tube 111 is arranged on the movable rod 120, so that the fixing tube 111 rotates circumferentially, and the fixing tube 111 has a resilient rotation stroke in the circumferential direction.

[0037] Specifically, referring to Figure 2 、 Figure 3 , the striking piece 112 includes a first section 113, a second section 114, and a third section 115. The whole striking piece 112 is made of silica gel material and is deformable. The first section 113 is fixedly connected to the movable rod 120. A metal sheet body 116 connected to the movable rod 120 is arranged inside the first section 113, and the outside of the first section 113 is wrapped on 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.

[0038] Referring to 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] In addition, through the three-stage striking piece 112, the initial rotational amount can be increased, and the original rotational speed of the metal sheet body 116 will be accelerated, thereby striking the striking block 130, which can increase the initial rotational speed and rotational angle of the fixed tube 111, and the circumferential rotation can form a better oscillation effect to make the debris fall. It should be noted that in this embodiment, the length of the metal sheet body 116 is greater than the distance between the movable rod 120 and the mating frame 140, so that when bent, the metal sheet body 116 always has a good tendency to return to its original state.

[0043] The driving mode of the movable rod 120 can be motor driving, gear driving or cylinder driving, as long as a reciprocating motion is formed. Under the two-way motion, the fixed tube 111 will generate two-way rotation and swing rotation through two return springs 131.

[0044] Embodiment 2: The difference from Embodiment 1 is that with reference to Figure 7 、 Figure 8 , the striking block 130 is inserted and slidably connected in the fixed tube 111. One end of the striking block 130 away from the striking piece 112 has a counterweight block 151. The part of the striking block 130 inserted in 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 on the outer wall of the fixed tube 111.

[0045] It should be noted that when the counterweight spring 152 is in the initial state, the distance from the counterweight block 151 to the central axis of the fixed tube 111 is greater than the distance from the striking block 130 to the central axis of the fixed tube 111. When the striking piece 112 collides with the striking block 130, the fixed tube 111 starts to rotate circumferentially. Due to the existence of the counterweight block 151 and the set distance, the counterweight block 151 will drive the sliding rod 150 to slide, so that the striking block 130 retreats towards 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 striking block 130. At the same time, after the movement ends, the counterweight spring 152 will reset, so that the striking block 130 resets to its original position.

[0046] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
