Description

Technical Field

[0001] This utility model relates to the field of bar stock processing technology, and in particular to a bar stock processing machine tool. Background Technology

[0002] Bar stock has a wide range of applications in modern society. After the bar stock is discharged from the die casting furnace, it needs to be cut to facilitate the discharge of subsequent bar stock and the storage of the discharged bar stock. The existing cutting method is to clamp the freshly discharged bar stock with two clamps on the left and right and then cut it with a sawing module. When the two clamps clamp the bar stock from the left and right, the bar stock is prone to slight bending. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, this utility model provides a bar processing machine tool that can ensure that the cut bars are straight and avoid slight bending of the bars.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a bar stock processing machine tool, including a machine tool body. The top of the machine tool body is provided with a sawing module and a clamping module. The clamping module includes clamping mechanisms arranged symmetrically at the front and rear. The sawing blade of the sawing module is located between the two clamping mechanisms. The clamping mechanism includes a first driver, a fixed clamping table, and a movable clamping block. The movable clamping block is located directly above the fixed clamping table. The first driver is used to drive the movable clamping block to move closer to / away from the fixed clamping table.

[0006] In this solution, the bar stock is discharged from the die-casting furnace and then moved to the machine tool body. When the bar stock needs to be sawed, the position where the bar stock needs to be sawed is moved to the underside of the sawing blade between the two fixed fixture tables. The first driver drives the moving clamping block to approach the corresponding fixed fixture table so that the bar stock is clamped from top to bottom to prevent the bar stock from shifting. Since the bar stock is clamped from top to bottom, the bar stock will not be slightly bent. Then the sawing blade of the sawing module cuts the bar stock. The cut bar stock falls onto the machine tool body and is discharged to the outside.

[0007] Preferably, the top of the machine tool body is also provided with a connection module, which includes a moving plate and a guide rail. The guide rail is arranged in a front-to-back direction and has a slider that can slide along the guide rail. The top of the slider is fixedly connected to the bottom of the moving plate. The sawing module and the clamping module are arranged on the top of the moving plate. The machine tool body is also provided with a second driver for driving the moving plate to move back and forth.

[0008] The second driver moves the moving plate forward so that its movement speed matches the bar's discharge speed, preventing the bar located at the rear from squeezing against the clamped section. After a section of the bar is sawn, the second driver moves the moving plate backward to reset, preparing for the next sawing operation.

[0009] Preferably, the machine tool body is also provided with a limiting block, which is located on the rear side of the moving plate and is used to limit the rear of the moving plate.

[0010] To prevent the movable plate from moving excessively backward, a limit block is provided on the rear side of the movable plate. When the movable plate moves to its maximum position, the limit block will block the movable plate and prevent it from moving further.

[0011] Preferably, the front side of the machine tool body is also provided with a material support assembly, which includes a material support frame, and multiple material support rollers are arranged side by side from front to back on the top of the material support frame.

[0012] Preferably, the material-bearing roller is arranged in a left-right direction.

[0013] Preferably, the machine tool body is also provided with a detector, which includes a bracket, a connecting block, and a detection component. The bracket is vertically arranged at the rear left end of the top of the machine tool body. The bracket has a through hole that runs horizontally. The connecting block passes through the through hole and can slide along the through hole. The bracket is provided with a locking element for locking / unlocking the connecting block. The detection component is located at the right end of the connecting block. The detection component includes an encoder and a roller. The roller is horizontally arranged above the encoder and is coaxially connected to the encoder shaft.

[0014] Preferably, the detection component is connected to the connecting block via a lifting connection mechanism. The lifting connection mechanism includes a first connecting plate, a second connecting plate, and two bolts. The first connecting plate is vertically arranged and has symmetrical strip-shaped connecting holes at the front and back. The strip-shaped connecting holes are vertically arranged, and the bolts correspond one-to-one with the strip-shaped connecting holes. The strip-shaped connecting holes penetrate the first connecting plate from left to right. The right end of the connecting block has a threaded hole corresponding to the position of the strip-shaped connecting hole. The threaded part of the bolt passes through the corresponding strip-shaped connecting hole and is threadedly connected to the corresponding threaded hole. The second connecting plate is horizontally arranged on the top right side of the first connecting plate. The encoder is fixedly connected to the bottom of the second connecting plate, and the shaft of the encoder passes vertically through the second connecting plate and is coaxially connected to the roller.

[0015] To ensure that the rollers remain in contact with the bar stock, the user can move the connecting block left and right, causing the connecting block to move the detection component left and right. When the detection component moves to the appropriate position, the connecting block is locked to the frame by the locking device. Then, the bolts are loosened and the vertical position of the first connecting plate is adjusted to change the vertical position of the detection component. When the vertical position of the detection component is adjusted to the appropriate position, the bolts are tightened to lock the first connecting plate and the connecting block.

[0016] The beneficial effects of this utility model are: the clamping module can clamp the bar material from top to bottom to prevent slight bending of the bar material; the connecting module can prevent squeezing of the bar material during sawing; and the detector can detect the length of the bar material.

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Example: A bar stock processing machine tool according to this example, such as Figures 1 to 4 As shown, the machine tool includes a machine tool body 1. The top of the machine tool body 1 is provided with a sawing module 2 and a clamping module. The clamping module includes clamping mechanisms 3 arranged symmetrically at the front and back. The sawing blade 21 of the sawing module 2 is located between the two clamping mechanisms 3. The clamping mechanism 3 includes a first driver 31, a fixed clamping table 32 and a movable clamping block 33. The movable clamping block 33 is located directly above the fixed clamping table 32. The first driver 31 is used to drive the movable clamping block 33 to move closer to / away from the fixed clamping table 32.

[0024] The top of the machine tool body 1 is also provided with a connection module, which includes a movable plate 4 and a guide rail 41. The guide rail 41 is arranged in a front-to-back direction. A slider 42 that can slide along the guide rail 41 is provided on the guide rail 41. The top of the slider 42 is fixedly connected to the bottom of the movable plate 4. The sawing module 2 and the clamping module are arranged on the top of the movable plate 4. The machine tool body 1 is also provided with a second driver for driving the movable plate 4 to move back and forth.

[0025] The machine tool body 1 is also provided with a limit block 43, which is located on the rear side of the moving plate 4 and is used to limit the rear of the moving plate 4.

[0026] The front side of the machine tool body 1 is also provided with a material support assembly 5, which includes a material support frame 51. Multiple material support rollers 52 are arranged side by side from front to back on the top of the material support frame 51. The material support rollers 52 are arranged in a left-right direction.

[0027] The machine tool body 1 is also equipped with a detector 6. The detector 6 includes a bracket 61, a connecting block 62 and a detection component. The bracket 61 is vertically installed on the left rear side of the top of the machine tool body 1. The bracket 61 has a through hole, which is arranged in a left-right direction. The connecting block 62 passes through the through hole and can slide along the through hole. The bracket 61 is equipped with a locking element for locking / unlocking the connecting block 62. The detection component is located on the right side of the connecting block 62. The detection component includes an encoder 63 and a roller 64. The roller 64 is horizontally installed above the encoder 63 and is coaxially connected to the shaft of the encoder 63.

[0028] The detection component is connected to the connecting block 62 via a lifting connection mechanism. The lifting connection mechanism includes a first connecting plate 65, a second connecting plate 66, and two bolts. The first connecting plate 65 is vertically arranged, and symmetrical strip-shaped connecting holes 651 are provided on the front and back of the first connecting plate 65. The strip-shaped connecting holes 651 are vertically arranged, and the bolts correspond one-to-one with the strip-shaped connecting holes 651. The strip-shaped connecting holes 651 pass through the first connecting plate 65 from left to right. The right end of the connecting block 62 is provided with a threaded hole corresponding to the position of the strip-shaped connecting hole 651. The threaded part of the bolt passes through the corresponding strip-shaped connecting hole 651 and is threadedly connected to the corresponding threaded hole. The second connecting plate 66 is horizontally arranged on the top right side of the first connecting plate 65. The encoder 63 is fixedly connected to the bottom of the second connecting plate 66. The shaft of the encoder 63 passes vertically through the second connecting plate 66 and is coaxially connected to the roller 64.

[0029] In this scheme, after the bar stock is discharged from the forging furnace, it moves onto the machine tool body. At this time, the left side of the bar stock contacts the roller, and the bar stock is fed from back to front directly below the sawing blade of the sawing module. Since the front end of the freshly discharged bar stock is uneven, it needs to be sawn to flatten the uneven front end. At this time, the second driver drives the moving plate to move forward at the same speed as the bar stock discharge speed. The first driver drives the moving clamping block to approach the corresponding fixed fixture table to clamp the bar stock. The sawing blade of the sawing module descends to cut off the front end of the bar stock. The encoder value is cleared to zero, and then the first driver drives the moving plate to move forward. As the moving clamp moves away from the corresponding fixed fixture, the bar stock is released. The second driver then drives the moving plate to move backward and reset. At this point, the front end of the bar stock is cut flat, and the bar stock is continuously discharged from the forging furnace. As the bar stock moves forward, the rollers drive the encoder to start counting. When the encoder value reaches the preset value, the second driver again drives the moving plate forward at the same speed as the bar stock discharge. The first driver then drives the moving clamp to approach the corresponding fixed fixture, clamping the bar stock again. The sawing blade of the sawing module descends and cuts the bar stock, and the encoder value is reset to zero. This process repeats. The cut bar stock moves to the receiving frame and is carried out by the receiving roller.

[0030] After the bar stock is sawn to a certain length, the second driver drives the moving plate to move backward and reset, preparing for the next sawing. To prevent the moving plate from moving too far backward, a limit block is provided on the rear side of the moving plate. When the moving plate moves to the maximum position, the limit block will block the moving plate and prevent it from continuing to move.

[0031] To measure the length of the sawn bar stock, and to ensure that the roller remains in contact with the bar stock, the user can move the connecting block left and right, causing the connecting block to move the detection component left and right. When the detection component moves to the appropriate position, the connecting block is locked to the frame by the locking device. Then, the bolts are loosened, and the vertical position of the first connecting plate is adjusted to change the vertical position of the detection component. When the vertical position of the detection component is adjusted to the appropriate position, the bolts are tightened to lock the first connecting plate and the connecting block.
