Description

Technical Field

[0001] The utility model relates to the technical field of circular-square pipe transformation, in particular to a die for transforming a circular pipe into a square pipe. Background Art

[0002] The die for transforming a hardware circular pipe into a square pipe is usually called a square pipe forming die, which is used to process circular metal pipes into pipes with a square cross-section. The existing die for transforming a hardware circular pipe into a square pipe includes an upper die and a lower die. The upper die includes a die cover, an upper die base, an upper die cushion block, a punch, a limit block and a guide pillar. The lower die includes a die cavity, a guide sleeve, a punch, a first lower die cushion block, a second lower die cushion block, a punch connecting rod, a lower die base, a ejector rod seat guide pillar, an ejector rod seat and an ejector rod.

[0003] When the existing die for transforming a hardware circular pipe into a square pipe is processing a circular pipe die, most of them use a limit block to limit the circular pipe die, and then use rollers to extrude and form the circular pipe die, without the effect of polishing the surface of the hardware circular pipe die. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a die for transforming a circular pipe into a square pipe, which can polish the surface of the die while transforming the circular pipe die into a square pipe die, making its surface smoother and flatter.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] The die for transforming a circular pipe into a square pipe includes a pipe shrinking mechanism and a processing mechanism. The processing mechanism is located on one side of the pipe shrinking mechanism. The pipe shrinking mechanism includes a machine body, on which a rolling device and a machine box are provided. The processing device includes a die. Both ends of the die are connected to a bottom material wall. A first groove is provided at the top of the bottom material wall. One side of the bottom material wall is connected to an outer wall. One end of the outer wall is provided with a motor, which is connected to a rotating shaft. A gear is provided on the rotating shaft. The gear is connected to a chain. One end of the chain is provided with a connecting platform. A gripper is provided above the connecting platform. The bottom end of the gripper is connected to a handle. Hydraulic rods are provided at both ends of the handle. One end of the hydraulic rod is articulated at the tail end of the handle, and the other end is articulated on the connecting platform.

[0007] Preferably, both sides of the die are connected to the bottom material wall, and the bottom end of the bottom material wall is connected to a bottom material table.

[0008] Preferably, plug blocks are provided at the top and tail ends of the hydraulic rod, and the plug blocks are articulated with movable bolts.

[0009] Preferably, the die is replaceable.

[0010] Preferably, a second groove is provided above the outer wall, and rollers are provided in the second groove. The rollers are installed on both sides of the connecting platform.

[0011] Preferably, a plurality of wheels are provided at the bottom of the fuselage.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] (1) By starting the motor in the utility model, the gripper pulls the round tube through the die. When the round tube passes through the die, it changes from a circular shape to a square shape due to the stretching effect, and the impurities on the surface of the round tube are also removed because of the friction between the surface of the round tube and the die, resulting in a polishing and grinding effect on the surface of the round tube die. Compared with the existing hardware round tube to square tube die, while the round tube die is changed into a square tube die, a polishing and grinding effect on the surface of the die is achieved.

[0014] (2) By collecting the impurities that fall on the bottom material table at one end of the die in the utility model, compared with the existing hardware round tube to square tube die, it is convenient for subsequent treatment of the impurities.

[0015] (3) By rotating the hydraulic rod in the utility model, the top end of the hydraulic rod is hinged to the handle, and the rotation of the hydraulic rod drives the handle to rotate, so that the size of the gripper becomes larger or smaller. Compared with the existing hardware round tube to square tube die, the fixing of round tube dies with different diameters is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. The implementation manners of the present utility model include but are not limited to the following embodiments.

[0022] First embodiment:

[0023] As Figures 1-4As shown in the figure, a metal round tube to square tube mold provided by the present utility model includes a tube shrinking mechanism 100 and a processing mechanism 200. The processing mechanism 200 is located on one side of the tube shrinking mechanism 100. The tube shrinking mechanism 100 includes a machine body 103, on which a rolling device 101 and a chassis 102 are provided. Before starting the processing of the round tube mold, the rolling device 101 is started through the chassis 102. The rolling device 101 has the same structure as the current tube shrinking machines on the market. One end of the round tube is inserted into the rolling device 101, and the rolling device 101 starts to extrude the inner round tube so that one end size can pass through the mold 203. The processing device 200 includes a mold 203. Both ends of the mold 203 are connected to a bottom material wall 202. A first groove 204 is provided at the top of the bottom material wall 202. One side of the bottom material wall 202 is connected to an outer wall 205. A motor 206 is provided at one end of the outer wall 205. The motor 206 is connected to a rotating shaft 207. A gear 208 is provided on the rotating shaft 207. The gear 208 is connected to a chain 209. A connecting platform 212 is provided at one end of the chain 209. A gripper 213 is provided above the connecting platform 212. The bottom end of the gripper 213 is connected to a handle 214. Hydraulic rods 215 are provided at both ends of the handle 214. One end of the hydraulic rod 215 is hinged to the tail end of the handle 214, and the other end is hinged to the connecting platform 212. The mold 203 is inserted into the first grooves 204 on both sides of the bottom material wall 202. One end of the round tube is inserted through the mold 203 and into the gripper 213. The hydraulic rod 215 is pushed to fix the gripper 213 and the round tube. The motor 206 is turned on. The motor 206 drives the rotating shaft 207 to rotate. The rotation of the rotating shaft 207 drives the gear 208 to rotate. The rotation of the gear 208 drives the chain 209 to move. The movement of the chain 209 drives the gripper 213 on the connecting platform 212 to move horizontally. The gripper 213 pulls the round tube through the mold 203. When the round tube passes through the mold 203, it changes from circular to square due to the stretching effect, and the impurities on the surface of the round tube are also removed due to the friction between the surface of the round tube and the mold 203, resulting in a polishing and grinding effect on the surface of the round tube mold.

[0024] By turning on the motor 206 in the present utility model, the gripper 213 pulls the round tube through the mold 203. When the round tube passes through the mold 203, it changes from circular to square due to the stretching effect, and the impurities on the surface of the round tube are also removed due to the friction between the surface of the round tube and the mold 203, resulting in a polishing and grinding effect on the surface of the round tube mold. Compared with the existing metal round tube to square tube molds, it realizes the polishing and grinding effect on the surface of the mold while changing the round tube mold into a square tube mold.

[0025] Second Embodiment:

[0026] On both sides of the mold 203, there are connecting bottom material walls 202. The bottom ends of the bottom material walls 202 are connected to the bottom material table 201. When the round pipe passes through the mold 203, friction is generated between the surface of the round pipe and the mold 203, causing the impurities on the surface of the round pipe to be rubbed off and fall on the bottom material table 201 at one end of the mold 203. After the round pipe mold processing is completed, the impurities on the bottom material table 201 can be collected, facilitating the subsequent treatment of the impurities.

[0027] By collecting the impurities that fall on the bottom material table 201 at one end of the mold 203, the present utility model is convenient for subsequent treatment of the impurities compared with the existing hardware round pipe to square pipe mold.

[0028] Third Embodiment:

[0029] At the top and the tail end of the hydraulic rod 215, there are insertion blocks 216. The insertion blocks 216 are hinged to the movable bolts 217. When fixing round pipe molds with different diameters, the bottom end of the hydraulic rod 215 is hinged to the connecting table 212. Rotate the hydraulic rod 215. The top end of the hydraulic rod 215 is hinged to the handle 214. The rotation of the hydraulic rod 215 drives the handle 214 to rotate, making the size of the gripper 213 larger or smaller, so as to realize the fixing function for round pipe molds with different diameters.

[0030] By rotating the hydraulic rod 215, with the top end of the hydraulic rod 215 hinged to the handle 214, the rotation of the hydraulic rod 215 drives the handle 214 to rotate, making the size of the gripper 213 larger or smaller. Compared with the existing hardware round pipe to square pipe mold, the present utility model realizes the fixing function for round pipe molds with different diameters.

[0031] Fourth Embodiment:

[0032] The mold 203 is replaceable. When grinding the round pipe into different shapes, only need to replace different molds.

[0033] Fifth Embodiment:

[0034] Above the outer wall 205, there is a second groove 210. Inside the second groove 210, there are rollers 211. The rollers 211 are installed on both sides of the connecting table 212. When the gripper 213 holds the round pipe and moves, the rollers 211 at the bottom of the connecting table 212 also move along the second groove 210 accordingly.

[0035] In use, start the rolling device 101 through the chassis 102. The rolling device 101 has the same structure as the pipe shrinking machines currently on the market. Insert one end of the round pipe into the rolling device 101. The rolling device 101 starts to extrude the internal round pipe so that the size of one end can pass through the mold 203. Insert the mold 203 into the first groove 204 on both sides of the base wall 202. Insert one end of the round pipe through the mold 203 into the gripper 213. Push the hydraulic rod 215 to fix the gripper 213 to the round pipe. Turn on the motor 206. The motor 206 drives the rotation of the rotating shaft 207. The rotation of the rotating shaft 207 drives the rotation of the gear 208. The rotation of the gear 208 drives the movement of the chain 209. The movement of the chain 209 drives the gripper 213 on the connecting table 212 to move horizontally. The gripper 213 pulls the round pipe through the mold 203. When the round pipe passes through the mold 203, it changes from circular to square due to the stretching effect, and the impurities on the surface of the round pipe are also removed due to the friction between the surface of the round pipe and the mold 203, resulting in a polishing effect on the surface of the round pipe mold.

[0036] The above embodiments are only one of the preferred embodiments of the present invention and should not be used to limit the protection scope of the present invention. Any meaningless changes or polishing made on the main design concept and spirit of the present invention, as long as the technical problems solved are still the same as those of the present invention, should be included in the protection scope of the present invention.
