Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a workbench used for sheet metal processing. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its notable feature is that the thickness of the same part is consistent. The product processed by sheet metal technology is called sheet metal parts, and the processing of sheet metal parts is usually carried out on a workbench.

[0003] When using the current workbench for sheet metal processing, workers often find that the sheet metal parts are limited on the workbench during processing to prevent them from shifting during processing. Currently, two clamps are usually used to clamp the two ends of the sheet metal parts. Since sheet metal parts are usually thin metal plates, simply clamping them with clamps without support at the bottom of the thin plates can easily cause them to bend. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a workbench for sheet metal processing.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a workbench for sheet metal processing, including a table body, a gantry fixedly connected to the table body, a hydraulic cylinder fixedly connected to the gantry, a processing tool is arranged on the piston rod of the hydraulic cylinder, a clamping structure is arranged on the table body, the clamping structure is mainly composed of two support plates, the two support plates are both arranged on the table body, a fixed block is fixedly connected to the table body, the fixed block is slidably connected to the two support plates, cylinders are respectively fixedly connected on both sides of the gantry, and clamping plates are fixedly connected to the piston rod of the cylinder.

[0006] The effects achieved by the above components are: the sheet metal is limited on the table, the hydraulic cylinder is started, the hydraulic cylinder drives the processing tool to descend to process the sheet metal, the sheet metal is placed on two support plates, and the positions of the two support plates can be adjusted according to the size of the sheet metal, the support plates can support the sheet metal, and then the two cylinders are started to drive the two clamping plates to clamp the sheet metal. If the sheet metal is U-shaped, the two side plates of the sheet metal are placed between the support plate and the clamping plate, so that the support plate and the clamping plate jointly clamp the side plate, making the position of the sheet metal more stable, thereby avoiding the current situation where the two ends of the sheet metal are usually clamped by two clamping plates. Since the sheet metal is usually a thin metal plate, it is easy to cause it to bend if it is simply clamped by a clamping plate without support at the bottom of the thin plate.

[0007] Preferably, a bidirectional threaded rod is rotatably connected to the gantry, the two sections of threads on the bidirectional threaded rod are in opposite directions, and the bidirectional threaded rod is threadedly connected to the two support plates.

[0008] The effect achieved by the above components is that since the two support plates slide at the upper limit position of the fixed block, rotating the bidirectional threaded rod can drive the two support plates to slide synchronously in opposite directions, making the position of the support plates more stable.

[0009] Preferably, a motor is fixedly connected to the gantry, and an output shaft of the motor is fixedly connected to the bidirectional threaded rod.

[0010] The effects achieved by the above components are: starting the motor, and the output shaft of the motor drives the bidirectional threaded rod to rotate, making the operation more convenient.

[0011] Preferably, a round rod is fixedly connected to the gantry, and the round rod is slidably connected to the two support plates.

[0012] The effect achieved by the above components is that the two support plates slide on the upper limit of the round rod, making the sliding process of the support plates more stable.

[0013] Preferably, a first rubber pad is fixedly connected to the support plate, and a second rubber pad is fixedly connected to the clamping plate.

[0014] The effects achieved by the above components are as follows: the first rubber pad and the second rubber pad can prevent the sheet metal from being damaged by the rigid contact between the support plate and the clamping plate, and can increase the friction force, thereby improving the limiting effect.

[0015] Preferably, a limiting structure is provided on the hydraulic cylinder, and the limiting structure is mainly composed of two limiting rods, both of which are fixedly connected to the piston rod of the hydraulic cylinder, and sliding grooves are respectively opened on the inner walls on both sides of the gantry, and the limiting rods are slidably connected to the sliding grooves.

[0016] The effects achieved by the above components are as follows: the two limiting rods slide in the sliding grooves in a limited manner, so that the lowering process of the processing tool is more stable and the processing accuracy can be improved.

[0017] Preferably, a sliding groove is provided on the limiting rod, a sliding block is slidably connected in the sliding groove, a sliding rod is slidably inserted on the sliding block, and a pressure plate is fixedly connected to one end of the sliding rod.

[0018] The effect achieved by the above components is: when the processing tool is lowered to the specified position, the two slide bars are slid so that the two pressure plates are pressed on the sheet metal part, making the displacement of the sheet metal part more stable during the processing.

[0019] Preferably, a spring is sleeved on the slide rod, one end of the spring is fixedly connected to the pressure plate, and the other end of the spring is fixedly connected to the slide block.

[0020] The effect achieved by the above components is: the spring is in a natural state Figure 4 In the middle state, when the limit rod descends, it drives the two pressure plates to descend, and the height of the pressure plates is lower than the height of the processing tool, so the two pressure plates will first contact the sheet metal. As the limit rod continues to descend, it will push the sliding rod to slide upward. At this time, the spring will gradually shrink, so the rebound force of the spring acts on the pressure plate, which can further enhance the limiting effect on the sheet metal.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are that, in the utility model, a clamping structure is provided to limit the sheet metal on the table body, and the hydraulic cylinder is started, and the hydraulic cylinder drives the processing tool to descend to process the sheet metal, and the sheet metal is placed on two support plates, and the positions of the two support plates can be adjusted according to the size of the sheet metal, and the support plates can support the sheet metal, and then the two cylinders are started to drive the two clamping plates to clamp the sheet metal. If the sheet metal is U-shaped, the two side plates of the sheet metal are placed between the support plate and the clamping plate, so that the support plate and the clamping plate jointly clamp the side plate, making the position of the sheet metal more stable. Since the two support plates are at the upper limit of the fixed block The two support plates can slide in the same position, so rotating the two-way threaded rod can drive the two support plates to slide in opposite directions synchronously, making the position of the support plates more stable. Starting the motor, the output shaft of the motor drives the two-way threaded rod to rotate, making the operation more convenient. The two support plates slide on the upper limit of the round rod, making the sliding process of the support plates more stable. The first rubber pad and the second rubber pad can prevent the sheet metal from being damaged by the rigid contact with the support plate and the clamping plate, and can increase the friction force, thereby improving the limiting effect, thereby avoiding the current situation where the two ends of the sheet metal are usually clamped by two clamps. Since the sheet metal is usually a thin metal plate, it is easy to cause it to bend if it is simply clamped by a clamp without support at the bottom of the thin plate.

[0027] Embodiment 1, as Figure 1 As shown, a workbench for sheet metal processing includes a table body 1, a gantry 2 is fixedly connected to the table body 1, a hydraulic cylinder 3 is fixedly connected to the gantry 2, and a processing tool is arranged on the piston rod of the hydraulic cylinder 3.

[0028] Reference Figure 2A clamping structure 4 is provided on the platform 1. The clamping structure 4 is mainly composed of two support plates 41. The two support plates 41 are both provided on the platform 1. A fixed block 42 is fixedly connected to the platform 1. The fixed block 42 is slidably connected to the two support plates 41. Cylinders 46 are fixedly connected to the two sides of the gantry 2. A clamping plate 47 is fixedly connected to the piston rod of the cylinder 46. The sheet metal is limited on the platform 1. The hydraulic cylinder 3 is started. The hydraulic cylinder 3 drives the processing tool to descend to process the sheet metal. The sheet metal is placed on the two support plates 41, and can be adjusted according to the size of the sheet metal. The positions of the two support plates 41 are adjusted, and the support plates 41 can support the sheet metal parts. Then, the two cylinders 46 are started to drive the two clamping plates 47 to clamp the sheet metal parts. If the sheet metal parts are U-shaped, the two side plates of the sheet metal parts are placed between the support plates 41 and the clamping plates 47, so that the support plates 41 and the clamping plates 47 clamp the side plates together, making the position of the sheet metal parts more stable, thereby avoiding the problem that the two ends of the sheet metal parts are usually clamped by two clamping plates. Since the sheet metal parts are usually thin metal plates, the bottom of the thin plate is clamped by simply using clamping plates. Without support, it is easy to cause bending. A bidirectional threaded rod 43 is rotatably connected to the gantry 2. The two sections of thread on the bidirectional threaded rod 43 are in opposite directions. The bidirectional threaded rod 43 is threadedly connected to the two support plates 41. Since the two support plates 41 slide on the upper limit of the fixed block 42, rotating the bidirectional threaded rod 43 can drive the two support plates 41 to slide in opposite directions synchronously, making the position of the support plates 41 more stable. A motor 44 is fixedly connected to the gantry 2. The output shaft of the motor 44 is fixedly connected to the bidirectional threaded rod 43. The motor 44 is started and the output shaft of the motor 44 is The shaft drives the bidirectional threaded rod 43 to rotate, making the operation more convenient. A round rod 45 is fixedly connected to the gantry 2, and the round rod 45 is slidably connected to the two support plates 41. The two support plates 41 slide on the round rod 45 to limit the position, making the sliding process of the support plate 41 more stable. A first rubber pad 48 is fixedly connected to the support plate 41, and a second rubber pad 49 is fixedly connected to the clamping plate 47. The first rubber pad 48 and the second rubber pad 49 can prevent the sheet metal from being damaged by the rigid contact with the support plate 41 and the clamping plate 47, and can increase the friction force, thereby improving the limiting effect.

[0029] Reference Figure 3 and Figure 4A limiting structure 5 is provided on the hydraulic cylinder 3. The limiting structure 5 is mainly composed of two limiting rods 51. The two limiting rods 51 are fixedly connected to the piston rod of the hydraulic cylinder 3. Sliding grooves 52 are respectively provided on the inner walls of the two sides of the gantry 2. The limiting rods 51 are slidably connected to the sliding grooves 52. The two limiting rods 51 limit and slide in the sliding grooves 52, so that the lowering process of the processing tool is more stable and the processing accuracy can be improved. A sliding groove 53 is provided on the limiting rod 51. A slider 54 is slidably connected in the sliding groove 53. A sliding rod 55 is slidably inserted on the slider 54. A pressing plate 56 is fixedly connected to one end of the sliding rod 55. When the processing tool is lowered to a specified position, the two sliding rods 55 are slid so that the two pressing plates 56 are pressed on the sheet metal parts, so that the displacement of the sheet metal parts during the processing is more stable. A spring 57 is sleeved on the sliding rod 55. One end of the spring 57 is fixedly connected to the pressing plate 56, and the other end of the spring 57 is fixedly connected to the slider 54. The spring 57 is in a natural state. Figure 4 In the middle state, when the limit rod 51 descends, the two pressure plates 56 are driven to descend, and the height of the pressure plates 56 is lower than the height of the processing tool, so the two pressure plates 56 will first contact the sheet metal. As the limit rod 51 continues to descend, the slide bar 55 will be pushed to slide upward. At this time, the spring 57 will gradually shrink, so the rebound force of the spring 57 acts on the pressure plate 56, which can further enhance the limiting effect on the sheet metal.

[0030] Working principle: limit the sheet metal on the platform 1, start the hydraulic cylinder 3, the hydraulic cylinder 3 drives the processing tool to descend to process the sheet metal, place the sheet metal on the two support plates 41, and the positions of the two support plates 41 can be adjusted according to the size of the sheet metal, the support plate 41 can support the sheet metal, and then start the two cylinders 46 to drive the two clamping plates 47 to clamp the sheet metal. If the sheet metal is U-shaped, place the two side plates of the sheet metal between the support plate 41 and the clamping plate 47, so that the support plate 41 and the clamping plate 47 can clamp the side plate together, making the position of the sheet metal more stable, thereby avoiding the current situation where the two ends of the sheet metal are usually clamped by two clamping plates. Since the sheet metal is usually a thin metal plate, it is easy to cause it to bend if it is simply clamped by a clamping plate without support at the bottom of the thin plate. Since the two support plates 41 are on the fixed block 4 2 limit sliding, so rotating the bidirectional threaded rod 43 can drive the two support plates 41 to slide synchronously in the opposite direction, making the position of the support plate 41 more stable, starting the motor 44, and the output shaft of the motor 44 drives the bidirectional threaded rod 43 to rotate, making the operation more convenient, and the two support plates 41 slide on the round rod 45 to limit the sliding, so that the sliding process of the support plate 41 is more stable, the first rubber pad 48 and the second rubber pad 49 can prevent the sheet metal from being damaged by the rigid contact with the support plate 41 and the clamping plate 47, and can increase the friction force, thereby improving the limiting effect, the two limit rods 51 limit sliding in the sliding groove 52, so that the lowering process of the processing tool is more stable, and the processing accuracy can be improved. When the processing tool is lowered to the specified position, the two sliding rods 55 are slid so that the two pressure plates 56 are pressed on the sheet metal, so that the displacement of the sheet metal during the processing is more stable, and the spring 57 is in a natural state. Figure 4 In the middle state, when the limit rod 51 descends, the two pressure plates 56 are driven to descend, and the height of the pressure plates 56 is lower than the height of the processing tool, so the two pressure plates 56 will first contact the sheet metal. As the limit rod 51 continues to descend, the slide bar 55 will be pushed to slide upward. At this time, the spring 57 will gradually shrink, so the rebound force of the spring 57 acts on the pressure plate 56, which can further enhance the limiting effect on the sheet metal.
