Description

Technical Field

[0001] The utility model belongs to the technical field of rubber processing, in particular to a rubber drilling device. Background Art

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber products are widely used in various aspects of industry and life. Rubber drilling devices are generally used for drilling.

[0003] Drilling device refers to the general term for equipment used to process holes in solid materials. Common drilling devices include electric drills, drilling machines, etc. When working, the electric drill rotates at high speed and rubs against the rubber surface to make holes in the rubber, thereby achieving the drilling effect.

[0004] The existing rubber drilling device may cause uneven surface of the drilling points and cannot drill multiple points at the same time by using a pressure drilling method. Therefore, a rubber drilling device is proposed to solve the above problems. Utility Model Content

[0007] Preferably, a bottom mold is provided inside the drill hole, a push column is provided at the bottom end of the bottom mold, a push rod is welded to the bottom of the push column, a sliding track is welded to the bottom end of the push rod, a slide groove is provided inside the sliding track, a push-pull lifting structure is provided in the slide groove, a push-pull rod is provided on one side of the push-pull lifting structure, and a pull ring is provided at the other end of the push-pull rod, thereby pushing the rubber scraps out of the hole.

[0008] Preferably, the push-pull lifting structure includes a slide plate, a triangular ring hole is dug on one side of the slide plate, a pin is provided inside the triangular ring hole, a connecting rod is provided outside the pin, and the connecting rod is welded to the ejector rod, thereby realizing the ejection operation.

[0009] Preferably, the three driven gears are connected to the top rod but in a non-fixed relationship, the bottom end of the spring is connected to a gasket, and the bottom end of the gasket is provided with a guide rail.

[0010] Preferably, three through-holes are formed on the top plate, and the through-holes are directly opposite to the drill bit. The rubber is pressed by the top plate, and the drill bit drills through the through-holes. This structural design plays a role in fixing the rubber.

[0011] The utility model is beneficial in that:

[0012] By changing the drill bit to a hollow design and increasing the number of drill bits, the friction area between the rubber and the drill bit is reduced, the drilling speed is accelerated, and the occurrence of uneven drilling points is avoided; by setting a push-pull lifting structure, the difficulty of removing scraps is reduced.

Since the drill bit 15 and the three driven gears are welded, the drill bit 15 rotates while the driven gears rotate. At this time, the hydraulic rod descends to drive the hydraulic plate 8. When the hydraulic plate 8 contacts the rubber, it continues to move downward. At this time, The guide column 11 will continue to move the top plate 9 downward along the guide rail 13, and when the drill bit 15 passes through the perforation 12, it starts to drill the rubber; when the drilling operation is completed, the hydraulic plate 8 rises, and the operator pulls the pull ring 37 at this time.
