Description

Technical Field

[0001] The utility model belongs to the technical field of plate shears, and particularly relates to an electric plate shear. Background Art

[0002] A plate shear is a machine that uses one blade to move reciprocally in a straight line relative to another blade to shear plates. It relies on the moving upper blade and the fixed lower blade, with a reasonable blade gap, to apply a shearing force to metal plates of various thicknesses, causing the plates to break and separate according to the required dimensions. The electric plate shear adopts a resistance key type clutch structure and an open-type gear drive, and uses relatively advanced electrical operations, with low noise and convenient operation and maintenance. During the production process of doors, the size and shape of the doors need to be cut. In the existing technology operation, the plate is placed on the operating table, and the end not placed on the operating table is held by the operator and then slowly pushed towards the bottom of the shear plate. This process not only requires the operator to keep an eye on the operation all the time, but also places a relatively large burden on the operator's arm if the operation time is long. Content of the Utility Model

[0003] The purpose of the utility model is to provide an electric plate shear with a simple structure and reasonable design to solve the above problems.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0008] As a further optimization solution of the present utility model, a backing plate is connected between the baffle plate and the moving rod, and the horizontal height of the backing plate is the same as that of the operating table.

[0009] As a further optimization solution of the present utility model, a sliding groove is provided at the lower end of the operating table, a support rod is connected to the moving rod, and the support rod and the sliding groove are correspondingly matched with each other.

[0010] As a further optimization solution of the present utility model, scales are provided on the operating table.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the work of the motor drives the gear on the rotating shaft to rotate, and the cooperation between the gear and the rack is used to drive the moving rod to move back and forth under the operating table. When the shearing work is carried out, the motor drives the moving rod to move towards the shearing mechanism, and the baffle plate pushes the plate inward, continuously shearing the plate, eliminating the need for manual long-term support, saving manpower and being fast and efficient.

[0013] 2. In the present utility model, the elongation movement of the hydraulic rod drives the upper cutter to move downward, and the pressing plate connected to the cutter also moves downward accordingly. The pressing head under the pressing plate presses on the plate. As the cutter moves downward, the spring in the groove contracts, and the tension of the spring itself is used to make the pressing head tightly press on the plate. Moreover, the lower end of the pressing head is made of rubber material, increasing the friction between the plates, facilitating the shearing of the plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Embodiment

[0022] As Figures 1-5 shown, an electric plate shearing machine includes a base 1. An operating table 2 is provided on the base 1. A support frame 3 is connected to the operating table 2. A shearing mechanism 4 is provided between the support frames 3. The shearing mechanism 4 includes a hydraulic rod 41. The hydraulic rod 41 is connected to the support frame 3. The output end of the hydraulic rod 41 is connected to an upper cutting knife 42. A lower cutting knife 8 is connected to the operating table 2 at a position corresponding to the upper cutting knife 42. When the hydraulic rod 41 performs an extension operation, it drives the upper cutting knife 42 to move downward to approach the lower cutting knife 8, and the cooperation between the upper cutting knife 42 and the lower cutting knife 8 is used to shear the plate. A push plate mechanism 5 is provided on the operating table 2. The push plate mechanism 5 includes a slide rail 51. The slide rail 51 is connected to the lower end of the operating table 2. A moving rod 52 is slidably fitted in the slide rail 51. One end of the moving rod 52 is connected to a baffle 53. A driving mechanism is provided on the other side of the moving rod 52. A blanking chute 6 is provided at the rear end of the operating table 2.

[0023] The driving mechanism includes a motor 55, which is installed on the base 1. The output end of the motor 55 is connected to a rotating shaft 56, which rotates in the base 1. A gear 57 is connected to the rotating shaft 56. A rack 54 is connected to the corresponding position of the gear 57 on the moving rod 52. The gear 57 meshes with the rack 54. The motor 55 drives the gear 57 on the rotating shaft 56 to rotate. The moving rod 52 is driven to move back and forth under the operating table 2 by the cooperation between the gear 57 and the rack 54. When the shearing work is in progress, the motor 55 drives the moving rod 52 to move in the direction of the shearing mechanism 4, and the baffle 53 pushes the plate inward to continuously shear the plate without long-term manual support. A pressing plate 43 is connected to one side of the upper cutting knife 42. A groove 44 is provided at the lower end of the pressing plate 43. A spring 45 is connected in the groove 44. A pressure head 46 is connected to the lower end of the spring 45 to control the hydraulic rod 41 when shearing the plate. The upper cutting knife 42 is extended to move downward, and the pressure plate 43 connected to the upper cutting knife 42 also moves downward. The pressure head 46 under the pressure plate 43 is pressed on the plate. As the spring 45 in the groove 44 of the upper cutting knife 42 moves downward, the tension of the spring 45 is used to press the pressure head 46 on the plate. The lower end of the pressure head 46 is made of rubber material to increase the friction between the plates, which is convenient for shearing the plates. A pad 58 is connected between the baffle 53 and the moving rod 52. The pad 58 is at the same level as the operating table 2. A slide groove 7 is provided at the lower end of the operating table 2. A support rod 59 is connected to the moving rod 52. The support rod 59 corresponds to the position of the slide groove 7 and cooperates with each other. When the plate is loaded, the longer the distance the moving rod 52 extends, the easier it is for the plate to be placed on the moving rod 52 to cause the other end to tilt. The support rod 59 stabilizes the position of the moving rod 52. A scale 9 is provided on the operating table 2 to facilitate controlling the shearing size of the plate.

[0024] When in use, first place the plate required for door assembly production on the operating table 2, and the other end of the plate is placed on the pad 58. The motor 55 is controlled to work, driving the rotating shaft 56 connected to its output end to rotate, so that the gear 57 connected to the rotating shaft 56 rotates, and the meshing transmission between the gear 57 and the rack 54 drives the moving rod 52 to move backward. When the plate is pushed to the marked size, the hydraulic rod 41 is extended to drive the upper cutter 42 to move downward, and the pressing plate 43 connected to the upper cutter 42 also moves downward. The pressure head 46 under the pressing plate 43 is pressed on the plate. As the spring 45 in the groove 44 moves downward at the position of the upper cutter 42, the tension of the spring 45 itself is used to press the pressure head 46 tightly on the plate, and the cooperation between the upper cutter 42 and the lower cutter 8 is used to shear the plate. The cut plate slides out of the device from the feed chute 6, and the baffle 53 continues to push the plate inward to continue shearing the plate without long-term manual support.

[0025] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
