[0004] In the related art, a lot of waste chips are generated during the processing of steel pipes on the press. Since the generated waste chips are difficult to be quickly cleaned and collected, it may affect the processing quality of the steel pipes. Content of the Utility Model

[0005] In order to enable the waste chips generated during the steel pipe processing to be quickly cleaned and collected, and to ensure the processing quality of the steel pipes, the present application provides a press for steel pipe processing.

[0006] The press for steel pipe processing provided by the present application adopts the following technical solutions:

[0007] A press for steel pipe processing, including a base and a workbench installed on the base. A gantry is fixed on the workbench. An upper arc-shaped plate is slidably installed on the gantry. The upper arc-shaped plate is located above the workbench. A lower arc-shaped plate opposite to the upper arc-shaped plate is also fixed in the middle section of the workbench. A support seat is fixed on the lower side of the lower arc-shaped plate, and the support seat is fixedly connected to the workbench. A discharge slot is opened in the middle section of the workbench. The support seat is located in the discharge slot, and there is a gap between the width direction of the support seat and the discharge slot. The surface of the workbench has an inclined surface that gradually slopes from the side far away from the discharge slot to the side close to the discharge slot. A collection groove communicated with the discharge slot is opened on the base. A cleaning mechanism for cleaning waste chips is also provided on the workbench.

[0008] By adopting the above technical solution, the steel pipe is clamped and fixed on the workbench by the upper arc plate and the lower arc plate approaching each other. During the processing, the waste chips generated will automatically move along the inclined surface of the workbench surface towards the discharge chute and fall into the collection chute. The cleaning mechanism further improves the cleaning effect, realizes the rapid collection and cleaning of waste chips, and ensures the processing quality of the steel pipe.

[0009] Optionally, the cleaning mechanism includes a cleaning plate slidably installed in the collection chute. The shape of the cleaning plate is the same as the cross-section of the collection chute. One side of the cleaning plate is fixed with a pull rod. The length direction of the pull rod is parallel to the length direction of the collection chute. A collection box for receiving waste chips is placed on one side of the base.

[0010] By adopting the above technical solution, by pulling the pull rod, the cleaning plate slides along the length direction of the collection chute, so that the waste chips falling into the collection chute are scraped and fall into the collection box.

[0011] Optionally, a handle is fixed to the end of the pull rod away from the cleaning plate.

[0012] By adopting the above technical solution, by pulling the pull rod with the handle, it is further convenient to pull the cleaning plate.

[0013] Optionally, a raised strip is fixed in the collection chute. The raised strip is parallel to the length direction of the collection chute. A guiding groove is formed on the cleaning plate. The raised strip is embedded in the guiding groove.

[0014] By adopting the above technical solution, during the process of the pull rod pulling the cleaning plate to slide horizontally in the collection chute, the guiding groove slides along the length direction of the raised strip, playing a guiding role and reducing the situation that the cleaning plate tilts during the sliding process, ensuring the cleaning effect on the waste chips.

[0015] Optionally, the raised strip has a cavity inside. A magnet strip is inserted into the cavity, and the material of the raised strip is plastic.

[0016] By adopting the above technical solution, the magnet strip is embedded in the cavity, so that the surface of the raised strip has magnetism and can automatically attract metal waste chips, reducing the situation that the waste chips entering the collection chute return to the workbench surface again.

[0017] Optionally, a connecting rod is fixed to the side of the cleaning plate close to the discharge chute. The connecting rod extends towards the side close to the lower arc plate.

[0018] By adopting the above technical solution, when the processing of the steel pipe is completed, during the process of pulling the cleaning plate to clean the collection chute, the connecting rod slides in the discharge chute to clean the discharge chute, reducing the situation that large particle waste chips are stuck in the discharge chute and causing poor discharge.

[0019] Optionally, a scraping plate is fixed to the side of the connecting rod away from the cleaning plate, and the scraping plate abuts against the surface of the workbench.

[0020] By adopting the above technical solution, when the steel pipe processing is completed and the waste chips need to be quickly cleaned, the pull rod is pulled to slide the cleaning plate, the connecting rod and the scraping plate at the same time. The scraping plate scrapes the waste chips on the surface of the workbench and slides them into the discharge chute along the inclined plane, and finally enters the collection box under the scraping of the cleaning plate and is quickly cleaned and collected.

[0021] Optionally, the support base includes a fixed sleeve and a plug-in block. The two ends of the fixed sleeve are fixedly connected to the inner wall of the discharge chute. The plug-in block is inserted into the fixed sleeve, and a plurality of shock-absorbing springs are fixed between the plug-in block and the fixed sleeve at intervals.

[0022] By adopting the above technical solution, when the upper arc plate moves downward to clamp the steel pipe, the shock-absorbing spring plays a buffering role to reduce the deformation of the steel pipe when it is clamped.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The steel pipe is clamped and fixed on the workbench by the mutual approach of the upper arc plate and the lower arc plate. The waste chips generated during the processing process will automatically move along the inclined plane of the workbench surface into the discharge chute and fall into the collection chute. The cleaning mechanism further improves the cleaning effect, realizes the rapid collection and cleaning of the waste chips, and ensures the processing quality of the steel pipe;

[0025] 2. During the process of the pull rod pulling the cleaning plate to slide horizontally in the collection chute, the guide groove slides along the length direction of the raised strip, playing a guiding role and reducing the inclination of the cleaning plate during the sliding process, ensuring the cleaning effect on the waste chips;

[0026] 3. When the steel pipe processing is completed and the waste chips need to be quickly cleaned, the pull rod is pulled to slide the cleaning plate, the connecting rod and the scraping plate at the same time. The scraping plate scrapes the waste chips on the surface of the workbench and slides them into the discharge chute along the inclined plane, and finally enters the collection box under the scraping of the cleaning plate and is quickly cleaned and collected.

[0031] The following will further describe the present application in detail with reference to the Figures 1 - 3 accompanying drawings.

[0032] An embodiment of the present application discloses a press for steel pipe processing.

[0033] Referring to Figure 1 , a press for steel pipe processing includes a horizontally arranged base 1. Four support feet 11 are fixed to the lower side of the base 1, and the four support feet 11 are located at the four end corners of the base 1 respectively, so that the base 1 is stably placed on the ground. A workbench 2 is fixedly installed on the base 1. A gantry 21 is fixed to the upper side of the workbench 2. Two vertically arranged cylinders 211 are fixed to the horizontal section of the gantry 21. The output ends of the two cylinders 211 are fixed with an upper arc plate 212, so that the upper arc plate 212 can slide up and down in the vertical direction, and the upper arc plate 212 is always located directly above the workbench 2. A transfer port 213 is formed through the vertical end of the gantry 21, and the steel pipe can move to the workbench 2 through the transfer port 213. A discharge chute 22 is formed in the middle of the workbench 2, and the length direction of the discharge chute 22 is parallel to the length direction of the steel pipe. A support base 23 is fixed in the discharge chute 22. A lower arc plate 24 is fixed to the upper side of the support base 23. The lower arc plate 24 is arranged opposite to the upper arc plate 212. When the upper arc plate 212 and the lower arc plate 24 approach each other, the steel pipe is clamped between the upper arc plate 212 and the lower arc plate 24. A cleaning mechanism 3 is also provided on the workbench 2, and the cleaning mechanism 3 cleans and collects the waste chips generated during the steel pipe processing, improving the processing quality.

[0034] Referring to Figure 2 and Figure 3, the support base 23 is fixed in the discharge chute 22, and there is a gap between the width direction of the support base 23 and the discharge chute 22 to facilitate the waste chips to enter the discharge chute 22. The support base 23 includes a plug-in block 231 and a fixed sleeve 232. The plug-in block 231 is fixedly installed on the lower side of the lower arc plate 24, and the plug-in block 231 is arranged along the length direction of the lower arc plate 24. The fixed sleeve 232 is located on the lower side of the plug-in block 231, and the plug-in block 231 and the fixed sleeve 232 are inserted into each other. The two ends of the fixed sleeve 232 are fixed in the discharge chute 22. A plurality of shock-absorbing springs 233 are also fixedly installed at intervals in the fixed sleeve 232. The plurality of shock-absorbing springs 233 are arranged at intervals along the length direction of the fixed sleeve 232. The upper end of the shock-absorbing spring 233 is fixed to the plug-in block 231, and the lower end of the shock-absorbing spring 233 is fixed to the fixed sleeve 232. After the steel pipe is placed on the lower arc plate 24, the upper arc plate 212 moves downward under the action of the cylinder 211 to press the steel pipe tightly against the lower arc plate 24, and the shock-absorbing spring 233 further plays a buffering role to reduce the deformation of the steel pipe when it is clamped.

[0035] The upper surface of the workbench 2 has an inclined surface that gradually inclines from the side away from the discharge chute 22 to the side close to the discharge chute 22, so that the generated waste chips can automatically slide along the inclined surface into the discharge chute 22. A collection groove 12 is opened on the base 1. The collection groove 12 communicates with the discharge chute 22, and the length direction of the collection groove 12 is parallel to the length direction of the discharge chute 22. The waste chips entering the discharge chute 22 will fall into the collection groove 12.

[0036] Referring to Figure 1 and Figure 2 , the cleaning mechanism 3 includes a cleaning plate 31 and a pull rod 32 fixed on the cleaning plate 31. The cleaning plate 31 is vertically arranged in the collection groove 12, and the size of the cleaning plate 31 is the same as the cross-section of the collection groove 12. The pull rod 32 is perpendicularly fixed on the cleaning plate 31, and the length direction of the pull rod 32 is parallel to the length direction of the collection groove 12. One end of the pull rod 32 away from the cleaning plate 31 is fixed with a handle 321. A collection box 4 is placed on one side of the base 1. The upper part of the collection box 4 is open to receive the waste chips falling from the collection groove 12; by pulling the pull rod 32 through the handle 321, the cleaning plate 31 slides horizontally along the length direction of the collection groove 12, and the waste chips falling into the collection groove 12 can be discharged and fall into the collection box 4.

[0037] Referring to Figure 2 and Figure 3, two raised strips 121 are also fixed inside the collection groove 12. The two raised strips 121 are parallel to each other and arranged along the length direction of the collection groove 12. On one side of the cleaning plate 31 close to the raised strip 121, two guiding grooves 311 are opened. The guiding grooves 311 are arranged in one-to-one correspondence with the raised strip 121, and the raised strip 121 is embedded in the guiding groove 311. When pulling the pull rod 32 to make the cleaning plate 31 slide, the guiding groove 311 and the raised strip 121 play a guiding role, reducing the situation where the cleaning plate 31 tilts.

[0038] The raised strip 121 is made of plastic material, and a cavity 1211 is opened in each raised strip 121. The cavity 1211 is opened along the length direction of the raised strip 121. A magnet bar 13 is placed in the cavity 1211. The magnet bar 13 can attract the waste chips falling into the collection groove 12, reducing the situation where the waste chips entering the collection groove 12 return to the surface of the workbench 2 again. When the collection groove 12 needs to be cleaned, first pull out the magnet bar 13, and then pull the cleaning plate 31 to move, which can clean the waste chips better.

[0039] Refer to Figure 3 , two parallel connecting rods 33 are also fixed on the upper side of the cleaning plate 31. The connecting rods 33 extend into the discharge groove 22, and scraping plates 34 are fixed at the upper ends of the connecting rods 33. The scraping plates 34 are respectively in contact with the inclined surfaces of the surface of the workbench 2. During the process of the cleaning plate 31 cleaning the collection groove 12, the connecting rods 33 and the scraping plates 34 simultaneously clean the waste chips remaining on the surface of the workbench 2 and in the discharge groove 22, improving the cleaning effect of the waste chips and facilitating the collection box 4 to collect the waste chips.

[0040] The implementation principle of a press for steel pipe processing in an embodiment of the present application is as follows:

[0041] When the steel pipe needs to be processed, the steel pipe is located on the lower arc-shaped plate 24. The upper arc-shaped plate 212 moves downward under the telescopic action of the cylinder 211, so that the steel pipe is clamped and fixed. The cleaning mechanism 3 cleans the waste chips generated during the processing. By pulling the pull rod 32, the cleaning plate 31 slides horizontally in the collection groove 12, the connecting rod 33 moves along the length direction of the discharge groove 22, and the scraping plate 34 scrapes the surface of the workbench 2, realizing the simultaneous cleaning of the workbench 2, the discharge groove 22 and the collection groove 12. The cleaned waste chips will finally fall into the collection box 4, having the effect of quickly cleaning the waste chips.

[0042] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore: All equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
