[0002] A bending machine is a metal processing device mainly used for bending metal plates into required shapes. When bending large plates, one end of the plate will tilt upward along the bending position, resulting in a risk of the plate falling during blanking. Now, a device convenient for blanking is proposed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a placement rack for precision-machined parts of a bending machine, which solves the above problems.

[0004] To achieve the above object, the utility model is realized through the following technical solutions: A placement rack for precision-machined parts of a bending machine includes a housing, and further includes: a support plate assembly for blanking the workpiece machine; the support plate assembly includes a support plate, a top rod and a sliding cylinder. The support plate is hinged to the housing, one end of the top rod is hinged to the support plate, the other end of the top rod is hinged to the sliding cylinder, the sliding cylinder is slidably connected to the housing through a chute in the housing, the sliding cylinder is threadedly connected to a lead screw, the lead screw is rotatably connected in the housing, and one end of the lead screw is fixedly connected to a dial.

[0005] Beneficial Effects

[0006] The utility model provides a placement rack for precision-machined parts of a bending machine, which has the following beneficial effects compared with the prior art:

[0007] After the workpiece is bent, the relevant technical personnel manually rotate the dial, causing the dial to drive the screw rod fixedly connected thereto to start rotating. As a result, the sliding cylinder threadedly connected to the screw rod starts to perform linear motion along its connection with the housing, causing the sliding cylinder to drive the ejector rod hinged thereto to move synchronously. The ejector rod starts to push the support plate hinged thereto, causing the support plate to start to fold upward with its connection with the housing as the fulcrum, so that the support plate fits against the upturned end of the workpiece. At this time, the relevant technical personnel start the motor, causing the motor to drive the gear meshed with its output gear to start rotating. As a result, the second screw rod fixedly connected to the center of the gear rotates synchronously, causing the slider threadedly connected to the second screw rod to start to perform linear motion along its connection with the support plate, causing the slider to push the link A hinged thereto. The link A starts to push the clamping plate hinged thereto, causing the slider B slidably connected to the other side of the clamping plate to start sliding, causing the link B hinged to the slider B to move synchronously. As a result, the clamping plate starts to slide smoothly under the cooperation of the link B and the link A, and the two clamping plates cooperate with each other to clamp the workpiece. The relevant technical personnel can then control the bending block of the bending machine to rise. At this time, the relevant technical personnel can pull the housing to remove the workpiece from the bending machine. At the same time, when the second screw rod rotates, the worm fixedly connected thereto starts to rotate, causing the worm to drive the worm wheel meshed with it to rotate synchronously. As a result, the screw rod A fixedly connected to the center of the worm wheel rotates synchronously, causing the scraper threadedly connected to the screw rod A to start to perform linear sliding along its connection, so as to scrape the bottom surface of the workpiece and remove rust and other impurities thereon.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0016] Please refer to Figures 1 to 5 , which is provided for an embodiment of the present utility model, a placement rack for precision-machined parts of a bending machine, including a housing 101, and further including:

[0017] A support plate assembly 2 for blanking the workpiece machine;

[0018] The support plate assembly 2 includes a support plate 201, a top rod 202 and a sliding cylinder 203. The support plate 201 is hinged to the housing 101. One end of the top rod 202 is hinged to the support plate 201, and the other end of the top rod 202 is hinged to the sliding cylinder 203. The sliding cylinder 203 is slidably connected to the housing 101 through a chute in the housing 101.

[0019] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific top rod 202 recorded in the above embodiment. For example, the top rod 202 should be made of high-hardness material. The purpose of this setting is to facilitate strengthening the load-bearing capacity of the top rod 202, so that when a heavier workpiece is placed on the support plate 201, the top rod 202 will not break under stress.

[0020] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific lead screw 204 recorded in the above embodiment. For example, the lead screw 204 should be a screw with a self-locking effect. The purpose of this setting is to facilitate preventing the sliding cylinder 203 from moving reversely under stress in this way.

[0021] Specifically, the sliding cylinder 203 is threadedly connected to the lead screw 204. The lead screw 204 is rotatably connected to the housing 101. One end of the lead screw 204 is fixedly connected to a dial 205.

[0022] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific housing 101 recorded in the above embodiment. For example, a counterweight is provided at the bottom of the housing 101. The purpose of this setting is to facilitate increasing the stability of the housing 101 in this way, and universal wheels are provided at the bottom of the housing 101 to facilitate pushing the device to transport the workpiece.

[0023] Specifically, clamping plates 206 are slidably connected to both sides of the support plate 201, and anti-slip rubber sheets are provided inside the clamping plates 206.

[0024] For the above example, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific clamping plates 206 described in the above embodiments. For example, the clamping plates 206 can be selected as L-shaped angle steels. The purpose of this setting is to facilitate the limitation of the workpiece through the short bottom side thereof, and further prevent it from slipping.

[0025] Specifically, one end of the link A 207 is hinged to the clamping plate 206, the other end of the link A 207 is hinged to the slider 208, and the slider 208 is slidably connected to the support plate 201.

[0026] For the above example, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific slider 208 described in the above embodiments. For example, a damping rubber strip is provided at the connection between the slider 208 and the housing 101. The purpose of this setting is to facilitate preventing abnormal noises during its sliding through this method.

[0027] Specifically, the slider 208 is threadedly connected to the second lead screw 209, and the second lead screw 209 is rotatably connected to the housing 101.

[0028] For the above example, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific second lead screw 209 described in the above embodiments. For example, the second lead screw 209 and the lead screw 204 can be selected as reciprocating lead screws. The purpose of this setting is that when the slider threaded thereon moves to one end, the movement direction of the slider can be quickly changed by continuously controlling the lead screw to rotate in the same direction.

[0029] Specifically, a shaft 302 is rotatably connected to the link A 207, the other end of the shaft 302 is rotatably connected to the link B 301, one end of the link B 301 is hinged to the support plate 201, and the other end of the link B 301 is hinged to a slider B 303, and the slider B 303 is slidably connected to the clamping plate 206.

[0030] For the above example, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific shaft 302 described in the above embodiments. For example, the shaft 302 can be selected as a bearing ring. The purpose of this setting is to facilitate reducing the friction at its connection through the bearing ring, thereby reducing wear and causing loosening of the connection between the link A 207 and the link B 301.

[0031] Specifically, a worm 306 is fixedly connected to the second lead screw 209. The worm 306 is meshed and connected with a worm wheel 307. A lead screw A 308 is fixedly connected to the center of the worm wheel 307.

[0032] Specifically, the lead screw A 308 is rotationally connected to the support plate 201. A scraper 309 is threadedly connected to the lead screw A 308. The lead screw A 308 is slidably connected to the support plate 201.

[0033] Specifically, a gear 304 is fixedly connected to the second lead screw 209. The gear 304 is meshed and connected with a gear fixedly assembled on the output shaft of a motor 305. The motor 305 is fixedly connected to the housing 101.

[0034] In the embodiment of the present utility model, after the workpiece is bent, the relevant technician manually rotates the dial 205, so that the dial 205 drives the lead screw 204 fixedly connected thereto to start rotating. Thus, the sliding cylinder 203 threadedly connected to the lead screw 204 starts to perform a linear motion along its connection with the housing 101. Thus, the sliding cylinder 203 starts to drive the ejector rod 202 hinged thereto to move synchronously, so that the ejector rod 202 starts to push the support plate 201 hinged thereto, so that the support plate 201 starts to turn up with the connection with the housing 101 as the fulcrum, so that the support plate 201 fits against the upturned end of the workpiece. At this time, the relevant technician starts the motor 305, so that the motor 305 drives the gear 304 meshed with its output gear to start rotating. Thus, the second lead screw 209 fixedly connected to the center of the gear 304 rotates synchronously. Thus, the slider 208 threadedly connected to the second lead screw 209 starts to perform a linear motion along its connection with the support plate 201. Thus, the slider 208 pushes the link A 207 hinged thereto, so that the link A 207 starts to push the clamping plate 206 hinged thereto. Thus, the slider B 303 slidably connected to the other side of the clamping plate 206 starts to slide, so that the link B 301 hinged to the slider B 303 starts to move synchronously. Thus, the clamping plate 206 starts to slide smoothly under the cooperation of the link B 301 and the link A 207, so that the two clamping plates 206 cooperate with each other to clamp the workpiece. The relevant technician can then control the bending block of the bending machine to rise. At this time, the relevant technician can pull the housing 101 to remove the workpiece from the bending machine. At the same time, when the second lead screw 209 rotates, the worm 306 fixedly connected thereto starts to rotate. Thus, the worm 306 drives the worm wheel 307 meshed with it to rotate synchronously. Thus, the lead screw A 308 fixedly connected to the center of the worm wheel 307 rotates synchronously. Thus, the scraper 309 threadedly connected to the lead screw A 308 starts to perform a linear slide along its connection with 201, so as to scrape the bottom surface of the workpiece and remove rust and other impurities thereon.

[0035] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0036] The fixed connection referred to in this application means a connection where there is no relative movement after the parts or components are fixed. It is divided into two types: detachable connection and non-detachable connection.

[0037] (1) Detachable connection: The components are fixed together using screws, splines, wedge pins, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedge pins), and they must be tightened appropriately.

[0038] (2) Non-detachable connection: mainly refers to welding, riveting, and mortise fitting, etc. Since it requires forging, sawing, or oxy-fuel cutting to disassemble during maintenance or replacement, the spare parts generally cannot be used a second time. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0039] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinged connection referred to in this application means that the component can rotate along an axial constraint.

[0040] In some cases, the sliding connection and the hinged connection referred to in this application can also be damped, such that the component has the ability to maintain at the desired position.

[0041] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
