Description

Technical Field

[0001] The utility model relates to the technical field of belt grinding machines, and specifically, to a belt grinding machine for processing stainless steel forgings. Background Art

[0002] A belt grinding machine is a grinding machine that uses a rapidly moving abrasive belt as a grinding tool for grinding and polishing. With the rapid development of grinding machine technology, belt grinding machines have evolved into high-efficiency and low-power finishing equipment. During the process of stainless steel forging, a belt grinding machine is required to perform grinding and polishing on it.

[0003] In the prior art, for the utility model with the authorization announcement number: CN213034318U and the name: A belt grinding machine with a rotatable grinding head, this patent rotates the grinding head by a rotating mechanism by a predetermined angle to perform multi-angle grinding on the grinding head. On the one hand, by grinding the workpiece at a rotating angle, the workpiece can form a smoother and flatter surface. On the other hand, it can also perform left and right rotatable grinding on the grinding head by angle rotation to grind a product with cross textures. Further, a product with an angle can be ground by rotating the grinding head by a predetermined angle;

[0004] In the prior art, for the utility model with the authorization announcement number: CN220145544U and the name: A rotary belt grinding machine, this patent conveys the workpiece to the lower part of the abrasive belt through a conveyor belt. Fixed components are arranged on the workbenches on both sides of the conveyor belt. The fixed components include a fixed motor, a fixed base plate, a fixed cylinder, a fixed pressing plate, and an anti-scratch pad. The fixed components are arranged under the abrasive belt. When the workpiece reaches the fixed components, by controlling the fixed motor to drive the fixed cylinder to push the fixed pressing plate forward to contact the workpiece for pressing, the anti-scratch pad can prevent the fixed pressing plate from directly touching the workpiece and causing damage to the workpiece when contacting the workpiece. Fixed components are arranged on both sides of the conveyor belt, and both sides of the fixed components are controlled by the fixed motor for pressing. When pressing, the conveyor belt is in a stopped state, so as to solve the problem that the workpiece cannot be fixed;

[0005] In the above-mentioned two patents, the grinding and polishing of the workpiece are both achieved by an abrasive belt in a rotating state. Since the abrasive belt will be worn after long-term use, which affects the grinding and polishing of subsequent workpieces, it is necessary to replace it. However, the existing belt grinding machines are rather cumbersome in the operation of disassembling the abrasive belt; for this reason, we propose a belt grinding machine for processing stainless steel forgings. Summary of the Utility Model

[0006] The present utility model provides a belt grinding machine for processing stainless steel forgings, which solves the problem in the related art that the abrasive belt will be worn after long-term use, affecting the grinding and polishing of subsequent workpieces. Therefore, it needs to be replaced. However, the existing belt grinding machines are rather cumbersome in disassembling the abrasive belt.

[0007] The technical solution of the present utility model is as follows: A belt grinding machine for processing stainless steel forgings includes a processing table. Above the processing table, there is an adjustment mechanism. The adjustment mechanism includes a support frame and an abrasive belt. The support frame is fixedly connected to the processing table. Two rotating rods are rotatably connected to the inner wall of the support frame. The outer surfaces of both rotating rods are fixedly connected with runner wheels. A fixed block is fixedly connected to the front of the support frame. Electric push rods are installed on one side and the other side of the fixed block. The output ends of both electric push rods are fixedly connected with connecting blocks. Telescopic rods are fixedly connected to the inner walls of both connecting blocks. Return springs are sleeved on the outer surfaces of both telescopic rods. Support blocks are fixedly connected to the outer surfaces of both telescopic rods. Tension wheels are rotatably connected to the outer surfaces of both support blocks. The runner wheels and the tension wheels are both in transmission connection with the abrasive belt.

[0008] Preferably, both the connecting block and the support block are fixedly connected with the return spring. A material guiding groove is fixedly connected to one side of the processing table. A cleaning opening is formed on the processing table. The position of the material guiding groove corresponds to that of the cleaning opening, and the material guiding groove is set in an inclined state, which can facilitate the cleaning of the debris generated during the processing of stainless steel workpieces.

[0009] Preferably, a second servo motor is installed on the back of the support frame. The output shaft end of the second servo motor is fixedly connected with the rotating rod. The second servo motor is installed on the back of the support frame. Connecting the second servo motor to the municipal power supply and starting it can drive the rotating rod to rotate in the inner wall of the support frame.

[0010] Preferably, a fixed frame is fixedly connected to the upper surface of the support frame. A servo cylinder is installed on the inner bottom wall of the fixed frame. The output end of the servo cylinder penetrates through the fixed frame and extends above the fixed frame. The output end of the servo cylinder is fixedly connected with a connecting frame. The fixed frame is fixed on the upper surface of the processing table, and the servo cylinder is installed on the inner bottom wall of the fixed frame. Controlling the fixed frame to start and its output end to expand and contract can drive the connecting frame to move up and down.

[0011] Preferably, two symmetrically arranged guide rods are slidably connected to the inner wall of the fixed frame. Both guide rods are fixedly connected with the connecting frame. Through the connection with the fixed frame and the connecting frame respectively, the guide rods can guide the movement of the connecting frame, making the connecting frame more stable during the up and down movement.

[0012] Preferably, a first servo motor is installed on one side surface of the connection frame. The output shaft end of the first servo motor is fixedly connected to a threaded rod rotatably connected to the connection frame. A slider slidably connected to the connection frame is threadedly connected to the outer surface of the threaded rod. The first servo motor is installed on the right side surface of the connection frame. Connecting the first servo motor to the municipal power supply and starting it can drive the threaded rod to rotate forward and backward inside the connection frame, and then drive the slider to slide reciprocally inside the connection frame.

[0013] Preferably, the upper surface of the slider is fixedly connected to a support plate slidably connected to the connection frame. An electric control magnetic table is installed on the upper surface of the support plate. After the slider moves, it can drive the support plate to slide reciprocally along the upper surface of the connection frame. The support plate drives the electric control magnetic table to move reciprocally. The stainless steel workpiece can be limited and fixed through the electric control magnetic table for subsequent grinding and polishing using a belt grinding machine.

[0014] Preferably, two bearings are embedded in the inner wall of the connection frame. The inner rings of both bearings are fixedly connected to the outer surface of the threaded rod. The bearings can make the threaded rod rotate more stably, reduce the resistance when the threaded rod rotates, and avoid jamming and swinging of the threaded rod during use.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] 1. Through the cooperative setting between the processing table and the adjusting mechanism in the present utility model, when forging and processing stainless steel using a belt grinding machine, the telescopic electric push rod can be used to drive the connection block to move. The connection block drives the support block to move through the telescopic rod and the return spring together, and then drives the tensioning wheel to support the abrasive belt. At the same time, since the connection block compresses the return spring after moving, causing it to produce elastic deformation, under the reset action of the return spring, the abrasive belt is always in a tensioned state. When the abrasive belt needs to be replaced due to wear, the output end of the electric push rod can be controlled to retract, driving the tensioning wheel to displace, so as to release the support for the abrasive belt and facilitate the disassembly and replacement of the abrasive belt, thereby avoiding affecting the subsequent grinding and polishing of stainless steel workpieces.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] As Figures 1 to 4 shown, this embodiment proposes a belt grinding machine for processing stainless steel forgings, including a processing table 1. A material guiding groove 3 is fixedly connected to one side surface of the processing table 1. A cleaning port is opened on the processing table 1. The position of the material guiding groove 3 corresponds to that of the cleaning port, and the material guiding groove 3 is set to be in an inclined state, which can facilitate the cleaning of debris generated during the processing of stainless steel workpieces.

[0027] An adjusting mechanism 2 is arranged above the processing table 1. The adjusting mechanism 2 includes a support frame 201 and an abrasive belt 204. The support frame 201 is fixedly connected to the processing table 1. Two rotating rods 202 are rotatably connected to the inner wall of the support frame 201. Rotating wheels 203 are fixedly connected to the outer surfaces of the two rotating rods 202. The processing table 1 fixedly supports the support frame 201, the rotating rods 202 fixedly support the rotating wheels 203, and the rotating rods 202 can rotate in the inner wall of the support frame 201.

[0028] A second servo motor 14 is installed on the back surface of the support frame 201. The output shaft end of the second servo motor 14 is fixedly connected to the rotating rod 202. The second servo motor 14 is installed on the back surface of the support frame 201. When the second servo motor 14 is connected to the municipal power supply and started, it can drive the rotating rod 202 to rotate within the inner wall of the support frame 201.

[0029] A fixed block 205 is fixedly connected to the front surface of the support frame 201. Electric push rods 206 are installed on both a side surface and another side surface of the fixed block 205. The output ends of the two electric push rods 206 are both fixedly connected to a connecting block 207. The fixed block 205 is fixed to the front surface of the support frame 201, and the two electric push rods 206 are respectively installed on the two side surfaces of the fixed block 205. By controlling the electric push rods 206 to start and their output ends to extend and retract, the connecting block 207 can be driven to move.

[0030] Expansion rods 208 are fixedly connected to the inner walls of the two connecting blocks 207. A return spring 2010 is sleeved on the outer surfaces of the two expansion rods 208. Support blocks 209 are fixedly connected to the outer surfaces of the two expansion rods 208. Both the connecting block 207 and the support block 209 are fixedly connected to the return spring 2010. Tension wheels 2011 are rotatably connected to the outer surfaces of the two support blocks 209. The runner 203 and the tension wheels 2011 are both in transmission connection with the abrasive belt 204.

[0031] The support block 209 is composed of a square block and two circular rods. The tension wheel 2011 can rotate on the circular rods. After the connecting block 207 moves, the support block 209 can be driven to move jointly through the expansion rod 208 and the return spring 2010. The support block 209 props up the abrasive belt 204 through the tension wheel 2011. At the same time, since the connecting block 207 will compress the return spring 2010 after moving, causing it to produce elastic deformation, under the reset action of the return spring 2010, the abrasive belt 204 is always in a tensioned state to ensure the processing of stainless steel workpieces.

[0032] A fixed frame 4 is fixedly connected to the upper surface of the support frame 201. A servo cylinder 5 is installed on the inner bottom wall of the fixed frame 4. The output end of the servo cylinder 5 penetrates through the fixed frame 4 and extends above the fixed frame 4. The output end of the servo cylinder 5 is fixedly connected to a connecting frame 6. The fixed frame 4 is fixed to the upper surface of the processing table 1, and the servo cylinder 5 is installed on the inner bottom wall of the fixed frame 4. By controlling the fixed frame 4 to start and its output end to extend and retract, the connecting frame 6 can be driven to move up and down.

[0033] Two symmetrically arranged guide rods 7 are slidably connected to the inner wall of the fixed frame 4. Both of the two guide rods 7 are fixedly connected to the connecting frame 6. Through the connection of the guide rods 7 with the fixed frame 4 and the connecting frame 6 respectively, the movement of the connecting frame 6 can be guided, so that the connecting frame 6 is more stable during the up and down movement process.

[0034] Example 2

[0035] As Figures 1 to 5 shown, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that a first servo motor 8 is installed on one side surface of the connection frame 6. A threaded rod 9 that is rotationally connected to the connection frame 6 is fixedly connected to the output shaft end of the first servo motor 8. A slider 10 that is slidably connected to the connection frame 6 is threadedly connected to the outer surface of the threaded rod 9. The first servo motor 8 is installed on the right side surface of the connection frame 6. Connecting the first servo motor 8 to the municipal power supply and starting it can drive the threaded rod 9 to rotate forward and backward in the inner wall of the connection frame 6, and then drive the slider 10 to reciprocally slide in the inner wall of the connection frame 6.

[0036] The upper surface of the slider 10 is fixedly connected to a support plate 11 that is slidably connected to the connection frame 6. An electric control magnetic table 12 is installed on the upper surface of the support plate 11. After the slider 10 moves, it can drive the support plate 11 to reciprocally slide along the upper surface of the connection frame 6. The support plate 11 drives the electric control magnetic table 12 to reciprocally move. The stainless steel workpiece can be limited and fixed through the electric control magnetic table 12 for subsequent grinding and polishing using a belt grinder.

[0037] Through the cooperation between the above structures, it is possible to realize the horizontal and vertical position adjustment of the positioned stainless steel workpiece, so that the belt grinder can perform grinding and polishing on different positions of the stainless steel workpiece, making the belt grinding more uniform and improving the flatness and smoothness of the stainless steel workpiece.

[0038] Two bearings 13 are embedded in the inner wall of the connection frame 6. The inner rings of the two bearings 13 are fixedly connected to the outer surface of the threaded rod 9. Through the bearings 13, the threaded rod 9 can rotate more stably, reduce the resistance when the threaded rod 9 rotates, and avoid the jamming and swinging of the threaded rod 9 during use.

[0039] The components in the drawings of the present utility model are only for style reference and do not serve as specific dimension standards. The specific dimensions are determined according to the actual requirements of production.

[0040] Working principle: When using a belt grinder to forge a stainless steel workpiece, connect two electric push rods 206 to the municipal power supply and control the two electric push rods 206 to start synchronously. The output end of the electric push rod 206 expands and contracts, which can drive the connecting block 207 to move. The connecting block 207 drives the support block 209 to move together through the telescopic rod 208 and the return spring 2010. The support block 209 drives the tensioning wheel 2011 to move, so as to realize the propping of the abrasive belt 204. At the same time, since the connecting block 207 compresses the return spring 2010 after moving, causing it to generate elastic deformation, under the reset action of the return spring 2010, the abrasive belt 204 is always in a tensioned state. Then, the rotating rod 202 can be controlled to rotate, and then the abrasive belt 204 is driven to rotate through the rotating wheel 203, so as to realize the grinding and polishing of the stainless steel workpiece. After that, when the abrasive belt 204 is worn and needs to be replaced, the output ends of the two electric push rods 206 can be controlled to retract synchronously, driving the tensioning wheel 2011 to displace, so as to release the propping of the abrasive belt 204, so as to disassemble and replace the abrasive belt 204, avoiding affecting the grinding and polishing of subsequent stainless steel workpieces, and thus improving the efficiency of forging and processing of stainless steel workpieces.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
