Description

Technical Field

[0001] The present invention relates to the technical field of vise processing, and more specifically, it relates to a cutting mechanism for vise processing. Background Art

[0002] In the fields of industrial production and machining, the vise is an important workpiece clamping tool, and the pretreatment of raw materials in its production and manufacturing process is particularly crucial. Currently, the production process of vises usually requires cutting long bar materials into section materials of specific sizes first, and then performing subsequent finishing processes. However, the existing bar cutting equipment generally adopts a single-piece cutting method. This traditional cutting method not only has low processing efficiency, but also requires frequent replacement and clamping of workpieces, prolonging the production cycle and affecting the overall production efficiency.

[0003] More prominent is that during continuous cutting operations, the existing equipment mainly relies on manual feeding operations. This manual feeding method not only increases the labor intensity of workers, but also easily leads to inconsistent cutting sizes due to human operation errors, affecting product quality. At the same time, manual feeding also has certain safety hazards. Especially during high-speed cutting, operators are prone to fatigue, increasing the risk of work-related injuries. Summary of the Invention

[0009] Preferably, two vertical grooves are formed on the vertical disk. Vertical strips corresponding to the vertical grooves are installed on the inner wall of the adjusting sleeve.

A pressurizing spring is fixedly installed on the sealing disk. The other end of the pressurizing spring is connected inside the energy storage tank. This energy storage system realizes the storage and release of pressure through the combination of the energy storage tank and the pressurizing spring, providing a continuous and stable working pressure and having a protective effect at the same time.

[0012] Preferably, a pre-tightening oil cylinder and a fixing oil cylinder are installed on the reciprocating plate. The pre-tightening pipe is connected to the pre-tightening oil cylinder through a hose. The fixing pipe is connected to the fixing oil cylinder through a hose.

Through the control of the hydraulic oil and the cooperation of the energy storage device, the continuous and stable clamping of the bar stock is realized. This design not only ensures the uniformity of the clamping force but also avoids the loosening and offset of the workpiece during the cutting process. Through the combined design of the energy storage tank and the pressure spring, the multi-stage adjustment and buffering of the pressure are realized. This design not only ensures the stability of the clamping force but also avoids damage to the workpiece and improves the processing accuracy. The combined design of the two-way sleeve and the piston disk realizes the synchronous control of the pre-tightening seat and the fixing seat.

[0033] Please refer to Figures 1 to 8, A cutting mechanism for vise processing, including a fixedly arranged fixing frame 11 and two transverse rods 12 installed on the fixing frame 11; it also includes a feeding mechanism. The feeding mechanism includes a bottom block 21 and a top block 22 slidably connected to the transverse rods 12.

A two-way rod 25 is slidably connected inside the two-way sleeve 24. A piston disc 26 is coaxially installed on the two-way rod 25. The piston disc 26 is slidably connected inside the two-way sleeve 24. A pre-tightening pipe 27 and a fixing pipe 28 are respectively installed on both sides of the two-way sleeve 24. An adjusting sleeve 29 is fixedly installed on the pre-tightening pipe 27. A one-way disc 210 is fitted and installed inside the adjusting sleeve 29. A plurality of control grooves 211 are opened on the one-way disc 210. A vertical disc 212 is slidably installed inside the adjusting sleeve 29. Control rods 213 corresponding to the plurality of control grooves 211 are installed on the vertical disc 212. The feeding mechanism also includes an intermediate sleeve 214 installed on the vertical disc 212. A limiting rod 215 is slidably installed inside the intermediate sleeve 214. The lower end of the limiting rod 215 is connected to the one-way disc 210. An internal spring 216 is sleeved on the limiting rod 215. One end of the internal spring 216 is connected to the limiting rod 215, and the other end of the internal spring 216 abuts inside the intermediate sleeve 214. Two vertical grooves 217 are opened on the vertical disc 212. Vertical bars 218 corresponding to the vertical grooves 217 are installed on the inner wall of the adjusting sleeve 29. The vertical grooves 217 are slidably connected to the vertical bars 218. A threaded sleeve 219 is threadedly installed on the adjusting sleeve 29. An embedded disc 220 is coaxially installed on the intermediate sleeve 214. The embedded disc 220 is rotatably connected inside the threaded sleeve 219. An energy storage tank 221 is connected and installed on the side wall of the adjusting sleeve 29. A sealing disc 222 is slidably connected inside the energy storage tank 221. A pressurizing spring 223 is fixedly installed on the sealing disc 222. The other end of the pressurizing spring 223 is connected inside the energy storage tank 221. A pre-tightening oil cylinder 224 and a fixing oil cylinder 225 are installed on the reciprocating plate 23. The pre-tightening pipe 27 is connected to the pre-tightening oil cylinder 224 through a hose. The fixing pipe 28 is connected to the fixing oil cylinder 225 through a hose. Two receiving seats 226 are respectively fixedly installed at both ends of the reciprocating plate 23. A pre-tightening seat 227 and a fixing seat 228 are respectively installed corresponding to the two receiving seats 226. The extending end of the pre-tightening oil cylinder 224 is connected to the pre-tightening seat 227. The extending end of the fixing oil cylinder 225 is connected to the fixing seat 228. A transverse cylinder 229 is installed at the lower end of the fixing frame 11. A synchronous block 230 is connected to the bottom block 21. The extending end of the transverse cylinder 229 is connected to the synchronous block 230.

[0034] When cutting the bar stock, first place multiple bar stocks on the two receiving seats 226. When the reciprocating plate 23 is pulled backward by the action of the transverse cylinder 229 until the top block 22 abuts against the bidirectional rod 25, then the fixing seat 228 moves upward without fixing the bar stock. At this time, the pre-tightening seat 227 presses downward on the bar stock, and then the pre-tightening seat 227 applies a continuous clamping pressure. Then, the transverse cylinder 229 drives the fixed bar stock towards the baffle 15 until multiple bar stocks abut against the baffle 15. Then, the bottom block 21 abuts against the bidirectional rod 25, causing the fixing seat 228 to press on the bar stock. At this time, the bar stock is fixed, and the pre-tightening seat 227 releases the fixation with the bar stock. Then, the cutting disc 34 reciprocally cuts multiple bar stocks. The cut bar stocks fall and are collected. At this time, the reciprocating plate 23 reciprocates to send the remaining bar stocks to the position of the baffle 15 for the next-side cutting.

[0035] When the reciprocating plate 23 moves backward away from the baffle 15 until the top block 22 abuts against the two-way rod 25, the piston disc 26 on the two-way rod 25 will be pushed accordingly. Then, the hydraulic oil in the space between the piston disc 26 and the pre-tightening tube 27 will be squeezed and flow into the adjusting sleeve 29 through the pre-tightening tube 27. Then, it will flow into the adjusting sleeve 29 relatively slowly through the control groove 211. Due to the one-way setting of the one-way disc 210, the one-way disc 210 will not release the connection. Then, the pressurized hydraulic oil will flow into the pre-tightening oil cylinder 224, then squeeze the pre-tightening seat 227 downward, and the pre-tightening seat 227 abuts against multiple bar materials and also flows into the energy storage tank 221, and then stores energy through the energy storage tank 221. The hydraulic oil squeezes the sealing disc 222, and then the pressure spring 223 is compressed. At this time, the pre-tightening process is completed. As the piston disc 26 moves towards the pre-tightening tube 27, the hydraulic oil in the fixed tube 28 and the fixed oil cylinder 225 is sucked out, and then the fixed seat 228 moves upward so that it does not fit against the bar materials. At this time, the pre-tightening of the bar materials is completed. Then, under the action of the transverse cylinder 229, the bar materials are driven to move. At this time, under the action of the transverse cylinder 229, the reciprocating plate 23 is driven to move, and then the top block 22 is disengaged from the contact with the two-way rod 25. Then, under the action of the energy storage tank 221, continuous pressure is applied to the pre-tightening seat 227, and the piston disc 26 slowly returns. Then, until the bar materials abut against the top plate, the positioning process is completed. At the same time, the bottom block 21 abuts against the two-way rod 25, and then the piston disc 26 moves towards the fixed tube 28. At this time, the hydraulic oil will be pressed into the fixed oil cylinder 225, and then the fixed oil cylinder 225 applies a thrust to the fixed seat 228, and the fixed seat 228 is fixedly pressed on the bar materials, thus completing the fixing process. As the piston disc 26 moves towards the fixed tube 28, the hydraulic oil between the piston disc 26 and the pre-tightening tube 27 will be sucked in. At this time, the one-way disc 210 will release the connection, and the hydraulic oil in the pre-tightening oil cylinder 224 and the energy storage tank 221 will be sucked into the two-way sleeve 24, thus completing the fixing process. Then, the cutting process can be carried out to complete the whole process.

[0036] When it is necessary to change the flow rate of the liquid flowing into the multiple control grooves 211, by rotating the threaded sleeve 219, the embedded disc 220 and the intermediate sleeve 214 can be driven to move up and down, and the vertical groove 217 is slidably connected in the vertical bar 218. At this time, the control rod 213 will be driven to move up and down. Since the lengths of the multiple control rods 213 are different, when different numbers of control rods 213 are inserted into the control grooves 211, different numbers of control grooves 211 can be connected, thus completing the control process.

[0037] The reciprocating mechanism also includes a plurality of guide rods 31 fixedly mounted on the fixed frame 11, a reciprocating block 32 is slidably connected to the plurality of guide rods 31, a cutting motor 33 is mounted on the reciprocating block 32, a cutting disc 34 is mounted on the cutting motor 33, a reciprocating motor 13 is fixedly mounted on the fixed frame 11, a lead screw 14 is mounted on the protruding end of the reciprocating motor 13, the lead screw 14 is threadedly connected to the reciprocating block 32, and a baffle 15 is mounted on the fixed frame 11.

[0038] When cutting, the reciprocating motor 13 is first used to drive the lead screw 14 to rotate, and then the lead screw 14 is threadedly connected to the reciprocating block 32, thereby driving the reciprocating block 32 to slide along the guide rod 31, and then the cutting motor 33 is used to make the cutting disc 34 cut the bar material. After cutting, the bar material will fall and be collected, and then the next operation will be performed on the bar material. After cutting, the cutting disc 34 will be reset, and the bar material will be sent to the position of the baffle 15 for the next cutting, thereby completing the whole process.

[0039] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
