Description

Technical Field

[0001] The invention belongs to the technical field of deburring, and in particular relates to a device for deburring side punch notches of a transfer multi-station die and an implementation method thereof. Background Art

[0002] In the production plants of various motor casings, casing products usually need to go through processes such as stretching, trimming, and notching. In multi-station production, notches are mainly formed by side punching, which will cause a problem of removing the side punching burrs. The burrs or metal wires after side punching are on the inside of the notch. To remove the burrs or metal wires, there is no way to solve this problem by pressing the burrs with a punch press.

[0003] Therefore, there is an urgent need for a multi-station die side punch notch deburring device to remove the side punch burrs. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for deburring the side punch notches of a transfer multi-station mold to solve the problems raised in the above background technology. The device for deburring the side punch notches of a transfer multi-station mold provided by the present invention has the characteristics of being able to remove the burrs on the side punches.

[0005] Another object of the present invention is to provide a method for implementing a device for transferring side punching notches of a multi-station mold to deburr the side punching notches.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for deburring the side punch notches of a multi-station mold, comprising a base and a lower pressure head, a grinding belt wheel group is installed on the upper end of the base, a motor is installed on one side of the base, a positioning seat is provided above the base, and a positioning groove corresponding to the grinding belt wheel group is provided on the positioning seat, the lower pressure head is arranged above the positioning seat, and a pressure seat is provided below the lower pressure head.

[0007] In order to grind and remove burrs, the grinding wheel assembly further includes a driven wheel and a driving wheel rotatably connected to the base, the driven wheel and the driving wheel are connected through a grinding belt, and the output end of the motor is connected to the driving wheel.

[0008] In order to achieve loading and unloading of the casing product without repeatedly starting and stopping the motor, thereby improving work efficiency and reducing labor intensity, a limit seat is further installed above the base, and the positioning seat and the limit seat are slidably connected via a plurality of lower guide shafts. A return spring is sleeved on the lower guide shaft and is located between the limit seat and the positioning seat.

[0009] In order to prevent the downward pressure of the lower pressure head from directly acting on the housing product and causing damage to the housing product, the pressure seat is further slidably connected to the lower pressure head through a plurality of upper guide shafts. A buffer spring is sleeved on the upper guide shaft and is located between the pressure seat and the lower pressure head.

[0010] Furthermore, in the present invention, a method for implementing a side punch notch deburring device for a multi-station die is provided, comprising the following steps:

[0011] (1) Place the housing product in the positioning groove of the positioning seat;

[0012] (2) The downward pressure head drives the pressure seat downward, pressing the casing product down until the positioning seat contacts the limit seat. At this time, the notch of the casing product contacts the abrasive belt;

[0013] (3) Remove the burrs at the notch by rotating the abrasive belt;

[0014] (4) After the action is completed, the lower pressure head drives the pressure seat to reset upward, and the positioning seat resets upward under the action of the reset spring, so that the casing product is separated from the sanding belt.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention places the casing product in the positioning groove of the positioning seat, drives the pressure seat to press the casing product to a limit position through the lower pressure head, drives the sanding wheel group to move through the motor, and removes the burrs of the casing product through the sanding wheel group, thereby realizing the removal of burrs generated by the side punching groove by the forward punching method.

[0017] 2. The present invention sets a reset spring so that in the initial position, after the casing product is placed on the positioning seat, the casing product does not contact the sanding belt. After the deburring action is completed, the restoring force of the reset spring is used to reset the positioning seat upward, so that the casing product is separated from the sanding belt, thereby eliminating the need to repeatedly start and stop the motor, improving work efficiency and reducing labor intensity.

[0018] 3. The present invention utilizes a buffer spring to buffer excessive downward pressure of the downward pressure head, thereby preventing the downward pressure of the downward pressure head from directly acting on the casing product, causing the casing product to be crushed.

[0034] Example 4

[0035] A method for implementing a side punch notch deburring device for a multi-station die includes the following steps:

[0036] (1) Place the housing product 9 in the positioning groove of the positioning seat 11;

[0037] (2) The pressing head 6 drives the pressing seat 5 downward, pressing the housing product 9 until the positioning seat 11 contacts the limiting seat 12. At this time, the notch of the housing product 9 contacts the abrasive belt 42.

[0040] In summary, the present invention places the casing product 9 in the positioning groove of the positioning seat 11, drives the pressure seat 5 to press the casing product 9 to a limit position through the pressure head 6, drives the sanding wheel group 4 to move through the motor 10, and removes the burrs of the casing product 9 through the sanding wheel group 4, thereby achieving the removal of burrs generated by the side punching groove by a positive punching method. The present invention sets the reset spring 3 so that in the initial position, after the casing product 9 is placed on the positioning seat 11, the casing product 9 does not contact the sanding belt 42. After the deburring action is completed, the restoring force of the reset spring 3 is used to reset the positioning seat 11 upward, so that the casing product 9 is separated from the sanding belt 42, thereby eliminating the need to repeatedly start and stop the motor 10, improving work efficiency, and reducing labor intensity. The present invention uses a buffer spring 8 to buffer the downward pressure of the pressure head 6 excessively, thereby preventing the downward pressure of the pressure head 6 from directly acting on the casing product 9, causing the casing product 9 to be crushed.
