Description

Technical Field

[0001] This utility model relates to the field of broaching technology, specifically to a continuous forming broaching machine for chamfering the inner hole of an iron cover. Background Technology

[0002] Iron lids are a type of metal component with a wide range of applications. They usually refer to "lid" products made of steel. Their core functions are sealing, protection, decoration, or load-bearing. After the iron lid is produced, some inner holes are usually made on its surface so that it can be fitted onto shafts, bolts, or pipes. The inner holes of some chemical drum iron lids can also be used to inject liquids or discharge gases.

[0003] After the inner hole of the iron cover is drilled, there are usually some burrs or impurities on the side wall of the inner hole. Therefore, it is necessary to use a broaching machine to chamfer the inner hole of the iron cover, and process the sharp edges at both ends of the inner hole into a gentle slope or arc surface. A broaching machine is a machine tool that uses a broach to perform high-precision and high-efficiency cutting of the workpiece. The broaching machine drives the broach to move continuously, and then penetrates the inner hole of the iron cover, thereby chamfering the inner hole to form a regular slope or arc surface.

[0004] During machining, when the broach passes through the iron cover, coolant needs to be sprayed next to it. This is because the broaching process involves high-speed, continuous cutting. The broach has a large contact area with the workpiece and a high cutting speed, which generates a lot of cutting heat and intense friction. Spraying coolant can cool it down.

[0005] When spraying coolant, there is a groove on the lower side of the broaching bed, so the sprayed coolant can fall directly into the groove. However, since the groove is integrated with the broaching bed, it is inconvenient to clean the coolant inside after the groove is full. It requires manual cleaning with tools, such as using a container to scoop it out, so the recycling efficiency is low. Utility Model Content

[0006] To overcome the above-mentioned defects, the present invention provides a continuous forming broaching machine for chamfering the inner hole of an iron cover, which solves the technical problem in the prior art that requires workers to use tools to clean the coolant during collection, which is quite troublesome.

[0007] According to one aspect, at least one embodiment of the present invention provides a continuous forming broaching machine for chamfering the inner hole of an iron cover, including a broaching machine body, a liquid collection tank, a rotating tilting assembly, a liquid baffle, and a support assembly. The liquid collection tank is disposed on the side of the broaching machine body via a push-pull assembly, and a liquid discharge groove is formed on the side of the liquid collection tank. The rotating tilting assembly is disposed on the push-pull assembly. The liquid baffle is slidably mounted through the liquid collection groove of the liquid collection tank. The support assembly is disposed on the side of the liquid collection tank for supporting the liquid baffle after it is pulled up.

[0008] Furthermore, the push-pull assembly includes a slide rail, a sliding block, a push-pull handle, and a fixing component. There are two slide rails, both of which are fixedly installed on the side of the broaching machine body. Two sliding blocks are slidably installed on each of the two slide rails. The push-pull handle is fixedly installed on the side of the two sliding blocks. The fixing component is disposed on the broaching machine body.

[0009] Furthermore, the fixing assembly includes a rotating shaft, a pull frame, and a rotating wheel. The rotating shaft is rotatably mounted on the side of the broaching machine body. The pull frame is U-shaped, and two pull frames are fixedly mounted on the rotating shaft. The rotating wheel is coaxially connected to the rotating shaft.

[0010] Furthermore, the rotating tilting assembly includes support blocks and a rotating shaft. The support blocks are slidably mounted on both slide rails, the rotating shaft is rotatably mounted between the two support blocks, and the bottom end of the liquid collection tank is fixedly connected to the rotating shaft.

[0011] Furthermore, the support assembly includes a fixing frame, a connecting rod, and a limiting assembly. The fixing frame is fixedly installed on the top of the liquid baffle, the connecting rod is L-shaped, and the connecting rod is fixedly installed on both sides of the fixing frame. The limiting assembly is located on the side of the liquid collection tank.

[0012] Furthermore, the limiting component includes a limiting block and a limiting rod. The limiting blocks are rotatably installed on both sides of the liquid receiving tank, and the top of the limiting block is provided with a limiting groove that matches the bottom of the connecting rod. The side of the limiting block is provided with a fixing hole, and the limiting rod is detachably installed in the fixing hole.

[0013] Furthermore, the top of the sliding block is provided with an L-shaped groove, and the L-shaped groove is in contact with the bottom of the liquid collection tank.

[0014] Furthermore, two fixing grooves are provided on both sides of the liquid receiving tank, and the limiting rod is adapted to the fixing groove.

[0015] The beneficial effects of this utility model are as follows: 1. In this utility model, when chamfering the inner hole of the iron cover, the worker pushes the liquid collection tank to the bottom of the iron cover and then fixes the liquid collection tank by the push-pull assembly. When chamfering, the sprayed coolant can fall directly into the liquid collection tank below. At this time, the baffle plate blocks the liquid draining groove on the side of the liquid collection tank, preventing the coolant from flowing out of the liquid draining groove. 2. In this utility model, after the chamfering is completed, the worker pulls the liquid collection box away from the side of the broaching machine body again by using the push-pull assembly, then opens the baffle plate and supports the baffle plate by the support assembly, and then rotates and tilts the liquid collection box by the rotating tilting assembly to pour out the coolant in the liquid collection box. During the tilting, a container can be placed on the side and below the liquid collection box to catch the poured coolant. In summary, this device, through the cooperation of the liquid collection tank, the rotating tilting assembly, the baffle plate, and the support assembly, can collect the sprayed coolant. After the chamfering is completed, the liquid collection tank can be rotated directly to pour out the coolant inside, which is quite convenient. Attached Figure Description

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-5As shown, it illustrates a continuous forming broaching machine for chamfering the inner hole of an iron cover according to an embodiment of the present invention. It includes a broaching machine body 1, a liquid collection tank 2, a rotating tilting assembly, a liquid baffle 3, and a support assembly. The liquid collection tank 2 is disposed on the side of the broaching machine body 1 via a push-pull assembly, and a liquid discharge groove is provided on the side of the liquid collection tank 2. The rotating tilting assembly is disposed on the push-pull assembly. The liquid baffle 3 is slidably installed through the liquid collection groove of the liquid collection tank 2. The support assembly is disposed on the side of the liquid collection tank 2 for supporting the liquid baffle 3 after it is pulled up.

[0026] When chamfering the inner hole of the iron cover, the operator first installs the iron cover in the through hole on the side of the broaching machine body 1 using a three-jaw chuck, ensuring that the inner hole of the iron cover is coaxial with the through hole of the broaching machine body 1. After aligning the inner hole of the iron cover with the through hole of the broaching machine body 1, the broach is placed into the through hole and secured on the moving frame inside the broaching machine body 1. The moving frame is connected to the output end of the hydraulic cylinder. Then, the operator starts the hydraulic cylinder of the broaching machine body 1, which drives the moving frame and the broach to pull into the broaching machine body 1, causing the broach to penetrate the inner hole of the iron cover and chamfer it. During chamfering, a spray pipe is installed on the side of the broaching machine body 1, with the outlet of the spray pipe aligned with the through hole. Coolant is sprayed onto the broach as it moves to cool it down. The broaching machine body 1 is replaceable, and the broach can be replaced to adapt to the processing requirements of different inner holes of iron covers, and the broach can also be repaired.

[0027] like Figure 2 and Figure 5 As shown, prior to this, the operator pushes the liquid collection tank 2 to the bottom of the spray pipe using the push-pull assembly. The push-pull assembly includes a slide rail 4, a sliding block 5, a push-pull handle 6, and a fixing assembly. There are two slide rails 4, both of which are fixedly installed on the side of the broaching machine body 1. Two sliding blocks 5 are slidably installed on each of the two slide rails 4. The push-pull handle 6 is fixedly installed on the side of the two sliding blocks 5. The fixing assembly is set on the broaching machine body 1 and includes a rotating shaft 7, a pull frame 8, and a rotating wheel 9. The rotating shaft 7 is rotatably installed on the side of the broaching machine body 1. The pull frame 8 is U-shaped, and two pull frames 8 are fixedly installed on the rotating shaft 7. The rotating wheel 9 is coaxially connected to the rotating shaft 7.

[0028] Specifically, the worker pushes the liquid collection tank 2 towards the broaching body 1. At this time, the sliding block 5 and the support block 10 slide on the slide rail 4. After the liquid collection tank 2 is moved below the spray pipe, the worker rotates the rotating wheel 9. The rotating wheel 9 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the pull frame 8 to rotate. Because the pull frame 8 is set in a U-shape, the pull frame 8 hooks the push-pull plate after rotating, thereby limiting the liquid collection tank 2. At this time, the chamfering work is performed, and the sprayed coolant falls into the liquid collection tank 2 below.

[0029] like Figure 3As shown, after the chamfering is completed, the coolant in the receiving tank 2 needs to be poured out in time. The operator continues to rotate the wheel 9 to separate the pull frame 8 from the push-pull handle 6, releasing the restriction on the receiving tank 2. Then the operator pushes the push-pull handle 6, thereby moving the receiving tank 2 away from the broaching machine body 1. After moving away a certain distance, the baffle plate 3 is lifted up by the support assembly, thereby leaking out the liquid discharge tank. The support assembly includes a fixed frame 12, a connecting rod 13 and a limiting assembly. The fixed frame 12 is fixedly installed on the top of the baffle plate 3. The connecting rod 13 is set in an L-shape, and the connecting rod 13 is fixedly installed on both sides of the fixed frame 12. The limiting assembly is set on the side of the receiving tank 2. The limiting assembly includes a limiting block 14 and a limiting rod 15. The limiting block 14 is rotatably installed on both sides of the receiving tank 2, and the top of the limiting block 14 is provided with a limiting groove that matches the bottom of the connecting rod 13. The side of the limiting block 14 is provided with a fixing hole, and the limiting rod 15 is detachably installed in the fixing hole.

[0030] Specifically, the worker pulls the fixing frame 12, causing the baffle plate 3 to rise. When the connecting rod 13 is above the limiting block 14, the worker's other hand rotates the limiting block 14 to below the connecting rod 13. Since there are two fixing slots on both sides of the liquid receiving tank 2, and the limiting rod 15 is compatible with the fixing slots, the limiting rod 15 is inserted into the fixing hole of the limiting block 14 and simultaneously into one of the fixing slots of the liquid receiving tank 2 to fix it. Then, the fixing frame 12 is lowered, and the connecting rod 13 is inserted into the limiting slot of the limiting block 14, thereby supporting the connecting rod 13 and the baffle plate 3. During liquid collection, the limiting block 14 can be rotated to the other end, and the limiting rod 15 can be inserted into the fixing hole of the limiting block 14 and the other fixing slot of the liquid receiving tank 2. Therefore, when the baffle plate 3 is pulled up, it will not block the connecting rod 13. It should also be noted that a sealing strip is installed between the baffle plate 3 and the liquid receiving tank 2.

[0031] like Figure 4 As shown, after the baffle plate 3 is pulled up, the internal coolant is poured out by rotating the tilting assembly. The tilting assembly includes a support block 10 and a rotating shaft 11. Support blocks 10 are slidably installed on both slide rails 4. The rotating shaft 11 is rotatably installed between the two support blocks 10, and the bottom end of the liquid receiving tank 2 is fixedly connected to the rotating shaft 11. Specifically, because the top of the sliding block 5 has an L-shaped groove, and the L-shaped groove is in contact with the bottom end of the liquid receiving tank 2, one end of the liquid receiving tank 2 (the end in contact with the sliding block 5) can be lifted, and the other end of the liquid receiving tank 2 can be rotated by the rotating shaft 11. At this time, the internal coolant leaks out through the liquid draining groove of the liquid receiving tank 2, thus being poured out.

[0032] Working principle: When chamfering the iron cover, the operator pushes the liquid collection tank 2 towards the broaching machine body 1. At this time, the sliding block 5 and the support block 10 slide on the slide rail 4. After the liquid collection tank 2 is moved below the spray pipe, the operator rotates the rotating wheel 9. The rotating wheel 9 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the pull frame 8 to rotate. After the pull frame 8 rotates, it hooks the push-pull plate, thereby limiting the liquid collection tank 2. At this time, the chamfering work is carried out, and the sprayed coolant falls into the liquid collection tank 2 below.

[0033] After collection is complete, the staff continues to rotate the wheel 9 to separate the pull frame 8 from the push-pull handle 6, and then pulls the fixing frame 12 to raise the baffle plate 3. When the connecting rod 13 is above the limiting block 14, the staff then rotates the limiting block 14 to below the connecting rod 13 with their other hand, inserts the limiting rod 15 into the fixing hole of the limiting block 14, and simultaneously inserts it into one of the fixing slots of the liquid collection tank 2 to fix it. Then, the fixing frame 12 is lowered, and the connecting rod 13 is inserted into the limiting slot of the limiting block 14 to support the connecting rod 13 and the baffle plate 3. Subsequently, the staff lifts one end of the liquid collection tank 2, and the other end of the liquid collection tank 2 can rotate through the rotating shaft 11. At this time, the coolant inside leaks out through the drain trough of the liquid collection tank 2 and is poured out.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
