Description

Technical Field

[0001] The utility model relates to the technical field of tricycle processing, in particular to a tricycle front face stamping and forming device. Background Art

[0002] A tricycle is a three-wheeled vehicle, modified from a bicycle, that can carry both people and goods. It became extremely popular after the 1930s, gradually replacing the rickshaw. The front face of a tricycle is a key component, and its production requires a stamping machine to form it.

[0003] However, the front face stamping forming device of a tricycle in the related art still has some shortcomings when used. Because the front face of a tricycle is generally arc-shaped, after stamping, the front face of the tricycle is easily pressed and fitted into the cavity of the lower mold, making demoulding more difficult and troublesome. At the same time, it is inconvenient to perform effective buffering protection during stamping. Under the large impact force of stamping, it is easy to cause damage to the upper and lower molds, thereby reducing the service life. Therefore, we propose a front face stamping forming device for a tricycle to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a three-wheeled vehicle front face stamping and forming device, which has four ejector rods that move upward synchronously, and can eject the front face of the three-wheeled vehicle out of the lower die cavity after stamping, making demoulding more convenient and efficient. At the same time, during stamping, it can provide effective buffering protection to avoid damage to the upper and lower dies caused by excessive impact force, thereby increasing the service life of the upper and lower dies.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: a three-wheeled vehicle front face stamping forming device, comprising a base, a lower die and an upper die for stamping the front face of the tricycle, the lower die is fixedly connected to the top of the base, the top of the base is fixedly connected to a gantry, the top of the gantry is fixedly connected to a hydraulic cylinder, the output shaft of the hydraulic cylinder is fixedly connected to a stamping plate, the upper die is fixedly connected to the bottom of the stamping plate, a guide buffer mechanism is provided between the stamping plate and the base, the bottom of the base is fixedly connected to a cover body, and an ejection demolding mechanism for demolding the stamped front face of the tricycle is provided between the cover body and the lower die.

[0006] The utility model is further configured as follows: the top of the stamping plate is threadedly connected with four upper screws, the upper die is fixedly connected to the bottom of the stamping plate by the four upper screws, both sides of the lower die are fixedly connected to two connecting plates, the top of the connecting plate is threadedly connected with lower screws, and the connecting plate is fixedly connected to the top of the base by the lower screws.

[0007] By adopting the above technical solution, according to the different specifications of the front face of the tricycle, the lower mold of the corresponding specification can be passed through the four push rods, and then the push rods are inserted into the corresponding upper through holes, thereby achieving the purpose of positioning and installing the lower mold, and then tightening the lower screws to install and fix the connecting plate and the lower mold, and through the upper screws, the upper mold of the corresponding specification is fixed to the bottom of the stamping plate, which is convenient for disassembly, assembly and replacement of the upper and lower molds, so that the front faces of tricycles of different specifications can be stamped and used, thereby improving the versatility of the device.

[0008] The utility model is further configured as follows: the guide buffer mechanism includes four guide columns fixedly connected to the top of the base and four buffer springs fixedly connected to the top of the base, the stamping plate is slidably sleeved on the outside of the four guide columns, the top end of the buffer spring is fixedly connected with a resistance ring, the resistance ring is slidably sleeved on the outside of the guide column, the resistance ring cooperates with the stamping plate, and the height of the resistance ring is greater than the height of the lower mold.

[0009] By adopting the above technical solution, the hydraulic cylinder is started, and the hydraulic cylinder drives the stamping plate and the upper die to move downward. Since the height of the contact ring is greater than the height of the lower die, when the stamping is downward, the stamping plate first contacts the contact ring and squeezes the buffer spring, thereby effectively buffering the instantaneous impact force when the stamping plate and the upper die move downward, avoiding damage to the upper and lower dies due to excessive impact force, and improving the service life of the upper and lower dies. Then, the upper die continues to move downward, and the upper die can perform stamping operations on the blank. After the stamping is completed, the hydraulic cylinder is started in the reverse direction to reset the upper die.

[0010] The utility model is further configured as follows: four sliding holes are opened on the top of the stamping plate, four guide posts are respectively slidably sleeved in the corresponding sliding holes, and four buffer springs are respectively sleeved on the outer sides of the corresponding guide posts.

[0011] By adopting the above technical solution, it is beneficial to guide the stamping plate and the buffer spring, making their movement more stable, thereby ensuring the stability and quality during stamping.

[0013] By adopting the above technical solution, the servo motor is started, which drives the rotation of the drive shaft and the driving gear. The driving gear drives the synchronous rotation of the two driven gears and the lifting screw. The two lifting screws drive the upward movement of the movable plate and the four ejector rods, thereby ejecting the front face of the tricycle after stamping out of the lower die, making the demolding of the front face of the tricycle more convenient and efficient, thereby improving production efficiency.

[0014] The utility model is further configured as follows: the movable plate is slidingly sleeved in the cover body.

[0015] By adopting the above technical solution, it is beneficial to guide the movable plate and make its movement more stable.

[0016] The utility model is further configured as follows: four upper through holes are opened at the bottom of the lower mold, four lower through holes are opened at the top of the base, and four ejector rods are respectively slidably sleeved in the corresponding upper through holes and lower through holes.

[0017] By adopting the above technical solution, the upper and lower through holes are used to guide the ejector rod, making its movement more stable. At the same time, when installing the lower mold, the upper through hole and the ejector rod are set to achieve the purpose of positioning the lower mold.

[0018] The beneficial effects of the utility model are:

[0019] 1. The utility model drives the downward movement of the stamping plate and the upper die through the hydraulic cylinder. Since the height of the contact ring is greater than that of the lower die, the stamping plate first contacts the contact ring and squeezes the buffer spring when the stamping plate and the upper die move downward, thereby effectively buffering the instantaneous impact force when the stamping plate and the upper die move downward, avoiding damage to the upper and lower dies due to excessive impact force, and improving the service life of the upper and lower dies.

The two lifting screws drive the upward movement of the movable plate and the four ejector rods, thereby ejecting the front face of the tricycle after stamping and forming upward out of the lower die, thereby making the demoulding of the front face of the tricycle more convenient and efficient, thereby improving production efficiency.

[0021] 3.
