Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a sheet metal processing device capable of automatically ejecting sheet metal parts. Background Technique

[0002] At present, sheet metal is a processing technology. There is no relatively complete definition of sheet metal yet. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold processing technology for metal sheets (usually below 6 mm), including shearing, punching / cutting / combining, folding, riveting, splicing, forming (such as automobile body), etc. Its remarkable feature is that the thickness of the same part is consistent.

[0003] Among them, sheet metal processing is the key technology that sheet metal technicians need to master and is also an important process for the forming of sheet metal products. Sheet metal processing includes traditional cutting and blanking, punching, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, the working principles and operating methods of various equipment, and also includes new stamping technologies and new processes. The processing of metal sheets of parts is called sheet metal processing.

[0004] After sheet metal is stamped, it is necessary for the operator to take out the stamped sheet metal from the mold. The process is relatively dangerous. If the operation is improper, the operator is extremely likely to have an accident. For this reason, we propose a sheet metal processing device capable of automatically ejecting sheet metal parts to solve the above problems, which can enable the operator to collect the stamped sheet metal automatically without approaching the hydraulic equipment. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art, and to propose a sheet metal processing device capable of automatically ejecting sheet metal parts.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A sheet metal processing device capable of automatically ejecting sheet metal parts, including: a workbench, a mold is fixedly installed in the middle of the workbench, a bracket is fixedly installed on the top of the workbench, hydraulic push rods are fixedly installed on both sides of the top of the bracket, an extrusion table is fixedly installed at the bottom of the two hydraulic push rods, and a material guiding mechanism is installed at the bottom of the extrusion table;

[0008] The material guiding mechanism includes a stamping groove opened in the middle of the bottom of the extrusion table, negative pressure grooves communicated and opened at both ends of the stamping groove, an extrusion plate movably installed in the stamping groove, a mounting frame fixedly installed on the side wall of the workbench, a buffer seat obliquely installed at the other end of the mounting frame, and a diversion plate movably installed in the inner cavity of the buffer seat, and the diversion plate corresponds to the stamping groove.

[0009] Preferably, a first electric push rod is fixedly installed on one side of the bottom of the buffer seat, and the other end of the first electric push rod is fixedly installed with the bottom of the diversion plate, which can push the diversion plate.

[0010] Preferably, a conveyor belt is fixedly installed at the bottom of the buffer seat, and the conveyor belt corresponds to the bottom of the diversion plate to convey the sheet metal after stamping.

[0011] Preferably, piston holes are formed at the four corners of the extrusion table, piston rods are movably installed in the four groups of piston holes, and clamping plates are fixedly installed at the bottoms of adjacent two groups of piston rods, which can limit the clamping plates.

[0012] Preferably, a spring is sleeved on the outer wall of each piston rod, and both sides of each spring are fixedly installed with the outer walls of the extrusion table and the clamping plate respectively, which can support the clamping plate.

[0013] Preferably, a negative pressure pump is fixedly installed on the top of the extrusion table, the negative pressure end of the negative pressure pump is communicated with two negative pressure grooves, a second electric push rod is fixedly installed on the top of the extrusion table, and the other end of the second electric push rod is fixedly installed with the middle of the extrusion plate, which can convey negative pressure to the negative pressure groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] In the present utility model, by synchronously driving the first electric push rod and the second electric push rod, while pushing the extrusion plate to push the sheet metal part down, the first electric push rod will push the diversion plate in the buffer seat to displace to the bottom of the stamping groove, and the extruded sheet metal part can be caught, and it is matched with the diversion plate at a certain inclination angle, and the sheet metal part can be automatically diverted to the conveyor belt to complete automatic material collection, avoiding the operator from taking out the sheet metal part from the workbench at risk;

[0016] By movably installing piston rods in the four groups of piston holes, and fixedly installing clamping plates at the bottoms of adjacent two groups of piston rods, when driving the hydraulic push rod to push the extrusion table downward, it will continuously approach the sheet metal on the mold. Since the clamping plates on both sides of the extrusion table move up and down along the piston rods and are matched with the supporting force of the springs on the piston rods, it can be ensured that when the stamping groove is continuously pressed inside the mold, the two clamping plates will firmly clamp both sides of the sheet metal to ensure the stability of the sheet metal during stamping.

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in 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.

[0022] Refer to Figures 1-3 , a sheet metal processing device capable of automatically ejecting sheet metal parts, including: a workbench 1, a mold 14 is fixedly installed in the middle of the workbench 1, a bracket 11 is fixedly installed on the top of the workbench 1, hydraulic push rods 12 are fixedly installed on both sides of the top of the bracket 11, an extrusion table 13 is fixedly installed at the bottom of the two groups of hydraulic push rods 12, and a material guiding mechanism is installed at the bottom of the extrusion table 13;

[0023] The material guiding mechanism includes a stamping groove 2 opened in the middle of the bottom of the extrusion table 13, negative pressure grooves 21 communicated and opened at both ends of the stamping groove 2, an extrusion plate 22 movably installed in the stamping groove 2, a mounting frame 23 fixedly installed on the side wall of the workbench 1, a buffer seat 24 obliquely installed at the other end of the mounting frame 23, and a flow guide plate 25 movably installed in the inner cavity of the buffer seat 24. The flow guide plate 25 corresponds to the stamping groove 2. By synchronously driving the first electric push rod 26 and the second electric push rod 35, while the extrusion plate 22 is pushed to drive the sheet metal part to descend, the first electric push rod 26 will push the flow guide plate 25 in the buffer seat 24 to displace to the bottom of the stamping groove 2, which can catch the extruded sheet metal part, and cooperate with the flow guide plate 25 at a certain inclination angle to automatically guide the sheet metal part onto the conveyor belt 27 to complete automatic material collection, avoiding the operator taking risks to take out the sheet metal part from the workbench 1.

[0024] Furthermore, piston holes 3 are provided at the four corners of the extrusion table 13. Piston rods 31 are movably installed in the four groups of piston holes 3. Clamping plates 32 are fixedly installed at the bottoms of adjacent two groups of piston rods 31, which can limit the clamping plates 32. A spring 33 is sleeved on the outer wall of each piston rod 31. Both sides of each spring 33 are fixedly installed on the outer walls of the extrusion table 13 and the clamping plate 32 respectively, which can support the clamping plate 32. When the driving hydraulic push rod 12 pushes the extrusion table 13 to move downward, it will continuously approach the sheet metal on the mold 14. Since the clamping plates 32 on both sides of the extrusion table 13 move up and down along the piston rods 31 and cooperate with the supporting force of the springs 33 on the piston rods 31, it can ensure that when the stamping groove 2 is continuously pressed inside the mold 14, the two clamping plates 32 will firmly clamp both sides of the sheet metal, ensuring the stability of the sheet metal during stamping.

[0025] Furthermore, a negative pressure pump 34 is fixedly installed on the top of the extrusion table 13. The negative pressure end of the negative pressure pump 34 is connected and installed with two negative pressure grooves 21. A second electric push rod 35 is fixedly installed on the top of the extrusion table 13. The other end of the second electric push rod 35 is fixedly installed with the middle part of the extrusion plate 22, which can convey negative pressure to the negative pressure grooves 21. When the driving negative pressure pump 34 conveys negative pressure to the negative pressure grooves 21, the sheet metal part closely attached to the stamping groove 2 will firmly adhere to the bottom of the extrusion table 13. At the same time, when the driving first electric push rod 26 pushes the flow guide plate 25 in the buffer seat 24 to displace to the bottom of the stamping groove 2, the negative pressure in the two negative pressure grooves 21 can be blocked, and the sheet metal can fall automatically.

[0026] Furthermore, a first electric push rod 26 is fixedly installed on one side of the bottom of the buffer seat 24. The other end of the first electric push rod 26 is fixedly installed with the bottom of the flow guide plate 25, which can push the flow guide plate 25. A conveyor belt 27 is fixedly installed at the bottom of the buffer seat 24. The conveyor belt 27 corresponds to the bottom of the flow guide plate 25 to convey the stamped sheet metal. By the first electric push rod 26 pushing the flow guide plate 25 in the buffer seat 24 to displace to the bottom of the stamping groove 2, the extruded sheet metal part can be caught and guided onto the conveyor belt 27 to collect the sheet metal.

[0027] During use, first place the sheet metal to be stamped on the top of the mold 14, drive the hydraulic push rod 12 on the driving bracket 11, and push the extrusion table 13 to stamp the sheet metal on the mold 14. After the sheet metal is stamped, the negative pressure pump 34 can be driven to convey negative pressure to the negative pressure groove 21. The sheet metal tightly attached to the stamping groove 2 is firmly attached to the bottom of the extrusion table 13. When driving the first electric push rod 26 and the second electric push rod 35, while the extrusion plate 22 is pushed to lower the sheet metal, the first electric push rod 26 will push the diversion plate 25 in the buffer seat 24 to displace to the bottom of the stamping groove 2, which can catch the extruded sheet metal and cooperate with the diversion plate 25 at a certain inclination angle to automatically divert the sheet metal onto the conveyor belt 27, completing automatic material collection and avoiding the operator from taking risks to take out the sheet metal from the workbench 1. At the same time, piston rods 31 are movably installed in all four piston holes 3, and clamping plates 32 are fixedly installed at the bottoms of adjacent pairs of piston rods 31. When the hydraulic push rod 12 is driven to push the extrusion table 13 downward, it will continuously approach the sheet metal on the mold 14. Since the clamping plates 32 on both sides of the extrusion table 13 move up and down along the piston rods 31 and cooperate with the supporting force of the springs 33 on the piston rods 31, it can ensure that when the stamping groove 2 is continuously extruded inside the mold 14, the two clamping plates 32 will firmly clamp both sides of the sheet metal to ensure the stability of the sheet metal during stamping.
